Behavioral interventions to promote condom use among women living with HIV: a systematic review update

Intervenções comportamentais para promover o uso de preservativo entre mulheres vivendo com HIV: atualização de uma revisão sistemática

Intervenciones conductuales para promover el uso del condón entre las mujeres que viven con el VIH: actualización de una revisión sistemática

Abstract:

Behavioral interventions have been essential components of HIV prevention approaches, especially those aimed to promote safe sexual practices. We conducted a comprehensive literature search without language restrictions between 1980 and July 2014 to identify randomized controlled trials or controlled studies investigating behavioral interventions which: included women living with HIV; focused on condom use promotion; presented/analyzed outcomes by gender; used a 3-month follow-up or more; and considered at least one HIV-related behavioral or biological outcome. Eight studies comprising a total of 1,355 women living with HIV were included in the meta-analyses, and 13 studies were qualitatively described. When compared to standard care or minimal support intervention, behavioral interventions did not demonstrate an effect on increasing consistent condom use at the 3-month follow-up (RR = 0.92; 95%CI: 0.73, 1.16; p = 0.48), 6-month follow-up (RR = 1.13; 95%CI: 0.96, 1.34; p = 0.15), and 12-month follow-up (RR = 0.91; 95%CI: 0.77, 1.08; p = 0.30). Behavioral interventions also failed to reach positive effect in reduction of unprotected sexual intercourse at 6-months (MD = -1.80; 95%CI: -4.21, 0.62; p = 0.14) and 12-months follow-up (MD = -1.39; 95%CI: -2.29, 0.21; p = 0.09). These findings should be interpreted with caution since they are based on a few small trials. New researches are needed to assess the potential gains from a combination of interventions that promote safe sexual behavior with a harm reduction and gender approach, particularly in developing countries where HIV infection rates remain high.

Resumo:

As intervenções comportamentais têm sido componentes essenciais das abordagens de prevenção do HIV, especialmente daquelas que visam promover práticas sexuais seguras. Realizamos uma pesquisa bibliográfica abrangente sem restrições de linguagem entre 1980 e julho de 2014, visando identificar ensaios randomizados e não randomizados que investigassem intervenções comportamentais que: incluíssem mulheres vivendo com HIV; focassem na promoção do uso de preservativo; apresentassem ou analizassem resultados por gênero; realizasse acompanhamento por três meses ou mais; e considerasse pelo menos um resultado comportamental ou biológico relacionado ao HIV. Oito estudos com um total de 1.355 mulheres vivendo com HIV foram incluídos nas meta-análises e 13 estudos foram qualitativamente descritos. Quando comparadas com o tratamento padrão ou intervenção mínima de apoio, as intervenções comportamentais não demonstraram efeito no aumento do uso do preservativo no seguimento de 3 meses (RR = 0,92; IC95%: 0,73, 1,16; p = 0,48), no seguimento de 6 meses (RR = 1,13; IC95%: 0,96, 1,34; p = 0,15), e no seguimento de 12 meses (RR = 0,91; IC95%: 0,77, 1,08; p = 0,30). Intervenções comportamentais também não demonstraram efeito positivo na redução de relações sexuais desprotegidas aos 6 meses (MD = -1,80; IC95%: -4,21, 0,62; p = 0,14) e aos 12 meses de seguimento (MD = -1,39; IC95%: -2,29, 0,21; p = 0,09). Estes resultados devem ser interpretados com cautela, uma vez que se baseiam em poucos estudos. São necessárias novas pesquisas para avaliar os potenciais ganhos de uma combinação de intervenções que promovam comportamentos sexuais seguros, com uma abordagem de gênero e de redução de danos, particularmente em países em desenvolvimento onde as taxas de infecção pelo HIV permanecem altas.

Resumen:

Las intervenciones comportamentales han sido componentes esenciales de los enfoques de prevención del VIH, especialmente de aquellos que tienen por objetivo promover prácticas sexuales seguras. Realizamos una investigación bibliográfica amplia, sin restricciones de lengua, entre 1980 y julio de 2014, teniendo por objetivo identificar ensayos randomizados controlados o estudios controlados que investigaran intervenciones comportamentales que: incluyeran a mujeres viviendo con VIH; se enfocaran en la promoción del uso de preservativo; presentaran o analizaran resultados por género; realizara un seguimiento durante tres meses o más; y considerara -por lo menos- un resultado comportamental o biológico relacionado con el VIH. Ocho estudios con un total de 1.355 mujeres viviendo con VIH se incluyeron en los metaanálisis y 13 estudios fueron cualitativamente descritos. Cuando se comparan con el tratamiento patrón o intervención mínima de apoyo, las intervenciones comportamentales no demostraron un efecto en el aumento del uso del preservativo en el seguimiento de 3 meses (RR = 0,92; IC95%: 0,73, 1,16; p = 0,48), en el seguimiento de 6 meses (RR = 1,13; IC95%: 0,96, 1,34; p = 0,15), y en el seguimiento de 12 meses (RR = 0,91; IC95%: 0,77, 1,08; p = 0,30). Las intervenciones comportamentales tampoco demostraron un efecto positivo en la reducción de relaciones sexuales desprotegidas a los 6 meses (MD = -1,80; IC95%: -4,21, 0,62; p = 0,14) y a los 12 meses de seguimiento (MD = -1,39; IC95%: -2,29, 0,21; p = 0,09). Estos resultados deben ser interpretados con cautela, ya que se basan en pocos ensayos. Es necesaria una nueva investigación para evaluar las potenciales ganancias de una combinación de intervenciones que promuevan comportamientos sexuales seguros, con un enfoque de género y de reducción de daños, particularmente en países en desarrollo, donde las tasas de infección por el VIH permanecen altas.

Background

HIV infection rates among women increased greatly in the 1990s and have remained stable since then. In 2014, women accounted for half of the 36.9 million cases of HIV infection in the world, mainly as a result of heterosexual transmission 11. World Health Organization. Global summary of the HIV/AIDS epidemic 2014. http://www.who.int/hiv/data/epi_core_july2015.png?ua=1.
http://www.who.int/hiv/data/epi_core_jul...
. Southern Africa is the epicenter of an epidemic marked by profound gender inequality, with HIV infection rates in women up to eight times higher than in men 22.

Curr HIV/AIDS Rep 2015; 12:207-15.. In Brazil, 35% of all AIDS cases reported in 2013 were in women (13,934 out of 39,501), or a female-to-male ratio of 1:1.8 for persons living with AIDS 33. Ministério da Saúde. Boletim epidemiológico AIDS/DST 2014. Brasília: Ministério da Saúde; 2014..

The large number of HIV cases in women has dramatic public health consequences. Women face challenges to interrupt the HIV transmission chain, prevent mother-to-child transmission, and maintain their own health. These challenges directly affect their sexual practices. Women living with HIV are at increased risk for sexually transmitted infections (STI) 44. Landes M, Thorne C, Barlow P, Fiore S, Malyuta R, Martinelli P, et al.

Healthy sexual behaviors are important buffers against the challenges faced by women living with HIV. Protected sexual intercourse through consistent condom use has been described as the most effective way to prevent both STI and HIV transmission 99. World Health Organization; Joint United Nations Programme on HIV/AIDS; United Nations Population Fund. Position statement on condoms and HIV prevention, 2014. Geneva: World Health Organization; 2014.. Despite positive advances (expansion of treatment and HIV testing) showed in the "15 by 15" report 1010. Joint United Nations Programme on HIV/AIDS. "15 by 15" - a global target achieved. Geneva: Joint United Nations Programme on HIV/AIDS; 2015. of the Global AIDS Response, sex protected by condom use remains a challenge. The focus on treatment as prevention has achieved recognized success; however, detectable HIV viral loads and imperfect adherence to antiretroviral therapy (ART) were not uncommon. Barrier methods such as condoms remain necessary to achieve broad reduction in HIV and other STI 1111. Weeks MR, Zhan W, Li J, Hilario H, Abbott M, Medina Z. Female condom use and adoption among men and women in a general low-income urban U.S. population. AIDS Behav 2015; 19:1642-54.), (1212. Shuper PA, Kiene SM, Mahlase G, MacDonald S, Christie S, Cornman DH, et al. HIV transmission risk behavior among HIV-positive patients receiving antiretroviral therapy in KwaZulu-Natal, South Africa. AIDS Behav 2014; 18:1532-40., considering that sexual transmission is responsible for most of new HIV cases 99. World Health Organization; Joint United Nations Programme on HIV/AIDS; United Nations Population Fund. Position statement on condoms and HIV prevention, 2014. Geneva: World Health Organization; 2014..

Among women, although the prevalence of sexual risk behavior generally declines after HIV diagnosis, a substantial group (30-40%) continues to engage in unprotected sexual intercourse 1313. Cicconi P, Monforte A, Castagna A, Quirino T, Alessandrini A, Gargiulo M, et al. Inconsistent condom use among HIV-positive women in the "Treatment as Prevention Era": data from the Italian DIDI study. J Int AIDS Soc 2013; 16:18591.), (1414. Weinhardt LS, Kelly JA, Brondino MJ, Rotheram-Borus MJ, Kirshenbaum SB, Chesney MA, et al. HIV transmission risk behavior among men and women living with HIV in 4 cities in the United States. J Acquir Immune Defic Syndr 2004; 36:1057-66.. Women are also less likely to use a condom when they have an HIV-infected partner than when the partners are HIV-negative or with unknown HIV status. Findings from a cross-sectional study including 978 women showed that 51% of unprotected sexual intercourse among HIV-infected women in the previous three months involved an HIV-infected partner (30% of unprotected sexual intercourse occurred with an HIV-uninfected partner, and 26% with a partner of unknown status) 1414. Weinhardt LS, Kelly JA, Brondino MJ, Rotheram-Borus MJ, Kirshenbaum SB, Chesney MA, et al. HIV transmission risk behavior among men and women living with HIV in 4 cities in the United States. J Acquir Immune Defic Syndr 2004; 36:1057-66.. Studies also reported higher levels of unprotected sex among women after ART initiation when compared to women before treatment initiation, independently of therapeutic response 1515. Wilson TE, Gore ME, Greenblatt R, Cohen M, Minkoff H, Silver S, et al. Changes in sexual behavior among HIV-infected women after initiation of HAART. Am J Public Health 2004; 94:1141-6., suggesting that beliefs regarding lower levels of infectivity under ART are also associated with less frequent condom use.

In addition to these findings, it is crucial to highlight the social determinants surrounding unprotected sexual behavior in women. Gender inequities have been cited as the main reason for unprotected sexual practices among women living with HIV 1010. Joint United Nations Programme on HIV/AIDS. "15 by 15" - a global target achieved. Geneva: Joint United Nations Programme on HIV/AIDS; 2015.), (1212. Shuper PA, Kiene SM, Mahlase G, MacDonald S, Christie S, Cornman DH, et al. HIV transmission risk behavior among HIV-positive patients receiving antiretroviral therapy in KwaZulu-Natal, South Africa. AIDS Behav 2014; 18:1532-40.), (1616. Santos NJ, Barbosa RM, Pinho AA, Villela WV, Aidar T, Filipe EMV. Contextos de vulnerabilidade para o HIV entre mulheres brasileiras. Cad Saúde Pública 2009; 25 Suppl 2:S321-33., including precarious socioeconomic conditions, low educational level, gendered power imbalances, intimate partner violence, and partner alcohol abuse. Reproductive intentions have also been emphasized as a reason for not using condoms 1717. Finocchario-Kessler S, Sweat MD, Dariotis JK, Trent ME, Kerrigan DL, Keller JM, et al. Understanding high fertility desires and intentions among a sample of urban women living with HIV in the United States. AIDS Behav 2010; 14:1106-14..

In order to avoid sexual risk behavior, programs for social and behavioral change have been encouraged and are seen as an essential component of HIV prevention approaches 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. The effectiveness of such prevention programs in increasing condom use and preventing HIV infection was demonstrated in a previous meta-analysis with HIV-seronegative participants 1919.

J Acquir Immune Defic Syndr 2006; 41:642-50.. Interventions guided by longer and more intensive behavioral theories were found to be more effective at promoting protected sexual intercourse.

Women living with HIV should be the target population for behavioral interventions, especially in countries with high HIV prevalence. These interventions must be based on a clear understanding of the social and cultural contexts shaping sexual behavior 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. Findings thus suggest that interventions addressing gender-specific issues, power imbalances, and culturally relevant information are more successful in reducing HIV transmission risk behavior among women living with HIV 1212. Shuper PA, Kiene SM, Mahlase G, MacDonald S, Christie S, Cornman DH, et al. HIV transmission risk behavior among HIV-positive patients receiving antiretroviral therapy in KwaZulu-Natal, South Africa. AIDS Behav 2014; 18:1532-40.), (2828. Wyatt GE, Longshore D, Chin D, Carmona JV, Loeb TB, Myers HF, et al. The efficacy of an integrated risk reduction intervention for HIV-positive women with child sexual abuse histories. AIDS Behav 2004; 8:453-62.), (2929. Wingood GM, DiClemente RJ, Mikhail I, Lang DL, McCree DH, Davies SL, et al. A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: the WiLLOW Program. J Acquir Immune Defic Syndr 2004; 37:S58-67.. Although an emerging body of evidence indicates that behavioral interventions can be effective, few studies have focused on women living with HIV. The absence of solid evidence in this area presents a gap in the field of prevention for this population. A previous meta-analysis investigated the effectiveness of behavioral interventions on promoting condom use among women living with HIV 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844.. The pooled analysis of five randomized controlled trials found little effect on behavioral interventions at promoting consistent condom use among HIV-positive women. Since these findings were based on a few small trials, the present study aimed to update and broaden this previous systematic review and meta-analysis 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844. in order to better understand the intervention effects on protected sexual behavior in women living with HIV.

Just three years after the original systematic review was performed, several relevant studies were published. Considering the low quality of the evidence found on behavioral interventions to promote condom use among women living with HIV, an update was expected to provide a more accurate picture of these interventions and their implications for public health research and decision-making. Some methodological shortcomings in the initial review could also be addressed (e.g., being based only on a dichotomous outcome, with few studies to conduct subgroup analyses), thereby expanding the findings. Finally, this update review aimed to critically describe and discuss all relevant behavioral interventions to promote condom use among women living with HIV, regardless of whether the study provided data for inclusion in the meta-analysis.

Methods

Since the current study aimed to update a previous review, we replicated the same methodological procedures described in Carvalho et al. 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844. and summarized as follows. We searched the following electronic databases regardless of language or publication status using the optimal sensitive search strategy developed by the Cochrane Collaboration 3131. Higgins JPT, Green SP. Cochrane handbook for systematic reviews of interventions. Version 5.0.0. Chichester: John Wiley; 2008.: (1) Cochrane Central Register of Controlled Trials (CENTRAL); (2) MEDLINE (PubMed); (3) EMBASE; (4) Latin American and Caribbean Health Sciences Literature (LILACS); (5) PsycInfo; (6) Social Science Citation Index (SocINDEX); and (7) Cumulative Index to Nursing and Allied Health Literature (CINAHL) through EBSCO. The previous search covered the period between January 1980 and May 2010, and this review used specific search terms to identify relevant studies from May 2010 to July 2014. We also examined reference lists from all pertinent reviews and published studies; we searched for unpublished studies in the WHO International Clinical Trials Registry Platform and the Clinicaltrials.gov database and in the International AIDS Conferences, National HIV Prevention Conference (through the Meeting Abstracts Database - NLM Gateway), the International Society for Sexually Transmitted Disease Research, and the Conference on HIV Pathogenesis and Treatment (through the conference websites). Finally, we contacted experts in the field for recommendations on additional intervention research reports and unpublished sources.

A systematic review and meta-analysis were conducted following the Cochrane Collaboration methods 3131. Higgins JPT, Green SP. Cochrane handbook for systematic reviews of interventions. Version 5.0.0. Chichester: John Wiley; 2008.. Studies included were randomized trials (RCT) or controlled studies (CCT) investigating HIV or STI behavioral interventions designed for people living with HIV which: (1) included HIV-positive women; (2) focused on condom use promotion; (3) presented outcomes by gender or reported having performed analyses by gender; (4) provided sufficient data to calculate effect sizes (in the meta-analysis portion); and (5) used a 3-month follow-up or more. Interventions could focus on providing information, counseling, health education, emotional well-being, skills training, coping strategies, or peer education related to HIV risk behaviors. There were no restrictions to the intervention's theoretical approach, setting, frequency, or duration. Protected sexual intercourse (or consistent condom use) was described as use of condoms in all vaginal, anal, or oral sexual relations with casual and/or steady partners. All other situations were considered inconsistent condom use (e.g., condom use "almost always" or "sometimes"). This update included a new outcome (reduction in unprotected sexual intercourse - continuous outcome).

The search was completed by one of the authors (T.R.G.). Citations retrieved from electronic searches were inspected by two authors (F.T.C. and E.R.F.) who independently screened studies for inclusion. Uncertainties were resolved by consensus. Following an initial screening, all potentially eligible studies were independently read by at least two authors (E.R.F., F.T.C., or T.R.G.) who assessed in detail the study design, types of participants, types of interventions, and outcome measures. Kappa coefficient indicated good agreement between reviewers both in the first review version (k = 0.76) and in the updated version (k = 0.69).

Using a standardized data extraction form, E.R.F., F.T.C., and T.R.G. extracted the following characteristics from each study that met the inclusion criteria: (1) description of study participants (e.g., sample size, demographic characteristics, country where the study was performed); (2) eligibility criteria for enrolment (e.g., HIV+ diagnosis); (3) details of the intervention (e.g., length of intervention and follow-up, individual or group modality, behavioral techniques); (4) assessment of risk of bias (e.g., study design, generation of allocation sequence, allocation concealment, blinding, loss to follow-up, inclusion of all randomized participants, and incomplete outcome data addressed); (5) outcome measures (e.g., acquisition of STIs or hepatitis B, self-reported protected anal, vaginal, or oral sexual intercourse); and (6) data analysis strategy.

Methodological quality was assessed through RevMan 5 (Cochrane Tech; http://tech.cochrane.org/revman/download) in accordance with the recommendations of the Cochrane Handbook of Systematic Reviews of Interventions3131. Higgins JPT, Green SP. Cochrane handbook for systematic reviews of interventions. Version 5.0.0. Chichester: John Wiley; 2008.. Risk of bias was categorized as "low risk", "high risk", or "unclear" and was listed in risk of bias tables separated by trial. We contacted the studies' authors to obtain additional information on missing data. Finally, the GRADE system was used to evaluate the overall quality of evidence for the outcome 3232. GRADE Working Group. Grading quality of evidence and strength of recommendations. BMJ 2004; 328:1490.), (3333. Guyatt G, Oxman AD, Akl EA, Kunz R, Vist G, Brozek J, et al. GRADE guidelines: 1. Introduction - GRADE evidence profiles and summary of findings tables. J Clin Epidemiol 2011; 64:383-94..

Statistical analysis was conducted according to Cochrane guidelines for systematic reviews of distinct treatments 3131. Higgins JPT, Green SP. Cochrane handbook for systematic reviews of interventions. Version 5.0.0. Chichester: John Wiley; 2008.. For dichotomous outcomes (consistent versus inconsistent condom use), the absolute numbers of participants reporting consistent condom use in each group (intervention and control) were extracted. The results for each intervention's effect were expressed as risk ratios (RR) with 95% confidence intervals (95%CI) and were combined for meta-analysis. For the continuous outcome (reduction in unprotected sexual acts), mean and standard deviations of condom use during sexual intercourse (relative frequency) for intervention and control groups were obtained. The difference in means (MD) and respective 95%CI were used to measure the absolute difference between the means in interventions and comparison groups. Since one included study was a cluster randomized trial, we used values of the intra-class correlation coefficient reported in a previous publication related to this intervention 3434. Rotheram-Borus MJ, le Roux IM, Tomlinson M, Mbewu N, Comulada WS, le Roux K, et al. Philani Plus (+): a Mentor Mother community health worker home visiting program to improve maternal and infants' outcomes. Prev Sci 2011; 12:372-88. to adjust trial analysis for clustering and enter its adjusted values in the meta-analysis. Consistent condom use (dichotomous outcome) was estimated using intention-to-treat analysis and included all subjects who were randomized, regardless of baseline condom use behavior. Reduction of unprotected sexual acts (continuous outcome) was estimated through an available case analysis, and the potential impact of missing data on the results was discussed.

The meta-analysis for both dichotomous and continuous outcomes used random-effects model in the RevMan 5.3 software. This strategy accounts for potential heterogeneity following unique intervention approaches developed in diverse study settings. Statistical heterogeneity between results of different studies was examined with the χ2 test. A p-value for a χ2 test of less than 0.10 indicated heterogeneity. An alternative approach to quantify the effect of heterogeneity is assessing the inconsistency (I2) among the results of studies with 95% uncertainty intervals. A value of 0% indicates no observed heterogeneity, and a value greater than 50% indicates substantial heterogeneity. Reporting bias was assessed by examining a funnel plot graph, which can detect small trial effects, even those resulting from publication bias.

The protocol for the first systematic review was planned to conduct subgroup analyses in order to explore possible sources of heterogeneity, but which were not performed because few studies were included. In the update, subgroup analyses were feasible for the dichotomous outcome (e.g., consistent condom use). We performed such analyses taking into account interventions that exclusively targeted (versus did not exclusively target) women living with HIV, and another considering the countries where the studies were done (North America versus Africa).

Results

In the first comprehensive search for this review 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844., out of 3,046 citations, 35 potentially relevant studies and their full-text versions were extracted. The search in the update was performed in July 2014 and retrieved 1,721 citations. Thirty-four intervention studies were selected for full-text review in the update, including 24 articles, 6 conference proceedings, and 4 registered trials. For the sake of comprehensiveness, we reported the results of the selection process just to the period from 2010 to 2014, when 3 new studies were included in the meta-analysis. The flowchart in Figure 1 summarizes the study selection process. The quantitative syntheses jointly describe the results from studies included in the first version (5 studies) and in the update (3 studies). Likewise, the qualitative syntheses comprised 13 studies (5 from the first version plus 8 added in the update).

Quality of the evidence

We performed a GRADE evaluation of the quality of evidence for all interventions included in this meta-analysis 3232. GRADE Working Group. Grading quality of evidence and strength of recommendations. BMJ 2004; 328:1490.), (3333. Guyatt G, Oxman AD, Akl EA, Kunz R, Vist G, Brozek J, et al. GRADE guidelines: 1. Introduction - GRADE evidence profiles and summary of findings tables. J Clin Epidemiol 2011; 64:383-94.. The GRADE system provided a structured approach to assess the quality of evidence across studies for each outcome included in the review according to risk of bias, publication bias, inconsistency, indirectness, and imprecision 3232. GRADE Working Group. Grading quality of evidence and strength of recommendations. BMJ 2004; 328:1490.), (3333. Guyatt G, Oxman AD, Akl EA, Kunz R, Vist G, Brozek J, et al. GRADE guidelines: 1. Introduction - GRADE evidence profiles and summary of findings tables. J Clin Epidemiol 2011; 64:383-94.. This classification indicated low quality of evidence for consistent condom use and very low quality of evidence for reduction in unprotected sexual acts. We downgraded the quality of evidence twice for both outcomes, based on the wide confidence intervals, indicating imprecision, and because results from different intervention protocols, with differences in duration, providers, and delivery cannot be generalized to diverse populations of women living with HIV (indirectness). We also downgraded the quality of evidence for the reduction in unprotected sexual relations, considering the inconsistency criteria, since it was not possible to conduct subgroup analyses to explore the sources of the moderate heterogeneity. The summary of findings can be accessed in Table 1 of the Supplementary Material: https://www.dropbox.com/s/tjhjhozyn8h235o/Supplementary%20Material%20reviewed.pdf?dl=0.

We specifically considered that the imprecision could also relate to the lack of sample size calculation in 3 3636. Sikkema KJ, Wilson PA, Hansen NB, Kochman A, Neufeld S, Ghebremichael MS, et al. Effects of a coping intervention on transmission risk behavior among people living with HIV/AIDS and a history of childhood sexual abuse. J Acquir Immune Defic Syndr 2008; 47:506-13.), (3939. Cornman DH, Kiene SM, Christie S, Fisher WA, Shuper PA, Pillay S, et al. Clinic-based intervention reduces unprotected sexual behavior among HIV-infected patients in KwaZulu-Natal, South Africa: results of a pilot study. J Acquir Immune Defic Syndr 2008; 48:553-60.), (4141. Saleh-Onoya D, Reddy PS, Ruiter RA, Sifunda S, Wingood G, van den Borne B.

Gilbert P, Ciccarone D, Gansky SA, Bangsberg DR, Clanon K, McPhee SJ, et al. Interactive "Video Doctor" counseling reduces drug and sexual risk behaviors among HIV-positive patients in diverse outpatient settings. PLoS One 2008; 3:e1988.), (3838. Holstad MM, DiIorio C, Kelley ME, Resnicow K, Sharma S. Group motivational interviewing to promote adherence to antiretroviral medications and risk reduction behaviors in HIV infected women. AIDS Behav 2011; 15:885-96.), (4040. Le Roux IM, Tomlinson M, Harwood JM, O'Connor MJ, Worthman CM, Mbewu N, et al. Outcomes of home visits for pregnant mothers and their infants: a cluster randomized controlled trial. AIDS 2013; 27:1461-71. and to the fact that the overall sample size across studies for both outcomes (in each follow-up assessment) appears too small to estimate a relevant public health impact from behavioral interventions on condom use. Based on the results of the meta-analysis, the optimal information size for the dichotomous outcome - consistent condom use - would require 4,356 participants in each intervention arm (e.g., P1 expected proportion in the control group 555/1,103= 0.50; P2 expected proportion in the intervention group 612/1,162 = 0.53; lowest p = 0.75; difference between P1 and P2 = 0.03; alpha and beta of 0.05 and 0.20, respectively 5151. Hulley SB, Cummings SR, Browner WS, Grady D, Hearst N, Newman TB. Designing clinical research. 2nd Ed. Philadelphia: Lippincott Williams & Wilkins; 2001.). Moreover, three of the studies included in the meta-analysis targeted both women and men, having lower percentages of female participants.

Assessment of publication bias

A meta-analysis can be vulnerable to publication bias if studies with less favorable results are not found. A useful test for publication bias is based on the funnel plot, which compares intervention effects estimated from individual studies against a measure of study size. In the absence of bias, the plot resembles a symmetrical inverted funnel 5252. Sterne JA, Egger M, Smith GD. Systematic reviews in health care: Investigating and dealing with publication and other biases in meta-analysis. BMJ 2001; 323:101-5.. However, the test is underpowered to distinguish chance from real asymmetry when less than 10 studies are included in the meta-analysis 3131. Higgins JPT, Green SP. Cochrane handbook for systematic reviews of interventions. Version 5.0.0. Chichester: John Wiley; 2008., which was the case in this review. Even so, in order to explore evidence of publication bias, we performed funnel plots for both outcomes. For the dichotomous outcome, the funnel plot was quite symmetrical, while in the continuous outcome, which includes fewer studies, plot asymmetry could be observed (see Figures 1 and 2 in the Supplementary Material: https://www.dropbox.com/s/tjhjhozyn8h235o/Supplementary%20Material%20reviewed.pdf?dl=0). Considering the small number of studies included in both meta-analyses, we can hypothesize that asymmetry may be also related to true heterogeneity among studies with different sizes rather than indicating publication bias, since there were differences in the intensity of the interventions as well as among HIV+ women who lived in highly diverse contexts in terms of social and individual vulnerability.

Effects of interventions

In this updated review, we conducted meta-analyses for two different outcomes: consistent condom use and reduction in unprotected sexual intercourse, respectively. A meta-analysis of the 8 studies did not demonstrate an effect of behavioral interventions on consistent condom use among women living with HIV when compared to standard care or minimal HIV support interventions. No intervention effects on consistent condom use were noted at the 3-month follow-up (RR = 0.92; 95%CI: 0.73, 1.16; p = 0.48), 6-month follow-up (RR = 1.13; 95%CI: 0.96, 1.34; p = 0.15), and 12-month follow-up (RR = 0.91; 95%CI: 0.77, 1.08; p = 0.30) or the overall effect (RR = 1.02; 95%CI: 0.92, 1.12; p = 0.74).

The overall result for consistent condom use showed evidence of moderate heterogeneity, indicating some inconsistency across study results (τ2 = 0.08; χ2 = 19.92, df = 12, p = 0.07, I2 = 40%). As shown in Figure 3, the higher heterogeneity for consistent condom use was found at the 6 month follow-up, probably related to positive results found by one study 3737. DeMarco RF, Chan K. The Sistah Powah structured writing intervention: a feasibility study for aging, low-income, HIV-positive black women. Am J Health Promot 2013; 28:108-18.. Subgroup analyses could not distinguish statistically significant differences in the intervention effect considering interventions that exclusively targeted (versus did not exclusively target) women living with HIV, or between the countries where they were conducted, i.e., in North America compared to Africa (see Figures 3, 4 and 5 in the Supplementary Material: https://www.dropbox.com/s/tjhjhozyn8h235o/Supplementary%20Material%20reviewed.pdf?dl=0).

A combination of particular characteristics of DeMarco & Chan's study 3737. DeMarco RF, Chan K. The Sistah Powah structured writing intervention: a feasibility study for aging, low-income, HIV-positive black women. Am J Health Promot 2013; 28:108-18. deserves to be mentioned, since it could be related to the positive results found in the meta-analysis. The Sistah Powah Structured Writing Intervention targeted aging, low-income, black women living with HIV, a group of women highly neglected by secondary prevention efforts because pregnancy is less likely and who face strong social vulnerability and stigma 5353. Lopes F, Buchalla CM, Ayres JRCM. Mulheres negras e não-negras e vulnerabilidade ao HIV/AIDS no estado de São Paulo, Brasil. Rev Saúde Pública 2007; 41:39-46.. The intervention was conducted in small groups and was the only one that was exclusively peer-led, involved culturally relevant narrative techniques, and helped to build a social support network in a community setting. Considering the population and the intervention's characteristics jointly, its success in promoting consistent condom use could be linked to a more effective approach to empower women living with HIV, stimulating their autonomy and the adoption of adapted strategies to deal with HIV according to gender and in socially challenging settings.

Figure 3:
Effectiveness of behavioral intervention versus standard care or minimal HIV support treatment in consistent condom use.

As shown in Figure 4, the meta-analysis for reducing unprotected sexual intercourse (e.g., increased condom use - continuous outcome) showed no significant effects of the behavioral interventions when compared to standard care or minimal HIV support interventions at 6-month (MD = -1.80; 95%CI: -4.21, 0.62; p = 0.14) and 12-month follow-up (MD = -1.39; 95%CI: -2.29, 0.21; p = 0.09). However, significant heterogeneity was detected (τ2 = 1.19, χ2 = 9.37, df = 4, p = 0.05, I2 = 57%), probably reflecting the diversity of studies included in the 6-month follow-up as well as the high imprecision observed in 1 study 3636.

Effects of a coping intervention on transmission risk behavior among people living with HIV/AIDS and a history of childhood sexual abuse. J Acquir Immune Defic Syndr 2008; 47:506-13.. We were unable to further explore heterogeneity with subgroup analyses due to the small number of studies included for this outcome.

Considering the statistical analyses conducted individually by the authors of the studies included in the meta-analyses, all but 1 found positive results for increased condom use 4141.

The current review also aimed to assess the effect of behavioral interventions on STI incidence, but only 2 studies 2929. Wingood GM, DiClemente RJ, Mikhail I, Lang DL, McCree DH, Davies SL, et al.

J Acquir Immune Defic Syndr 2004; 37:S58-67.), (4141. Saleh-Onoya D, Reddy PS, Ruiter RA, Sifunda S, Wingood G, van den Borne B. Condom use promotion among isiXhosa speaking women living with HIV in the Western Cape Province, South Africa: a pilot study. AIDS Care 2009; 21:817-25. assessed this outcome. The studies had different timing of follow-up assessments and 1 one 2929. Wingood GM, DiClemente RJ, Mikhail I, Lang DL, McCree DH, Davies SL, et al. A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: the WiLLOW Program. J Acquir Immune Defic Syndr 2004; 37:S58-67. presented adequate data to be grouped by results related to STI. One study found significantly higher incidence of Chlamydia trachomatis (OR = 0.21; 95%CI: 0.07, 0.59; p < 0.05), Neisseria gonorrhoeae (OR = 0.10; 95%CI: 0.02, 0.49; p < 0.05), and Trichomona vaginalis (OR = 0.06; 95%CI: 0.01, 0.46; p < 0.05) in the control group than in the intervention at 3 months follow-up 4141. Saleh-Onoya D, Reddy PS, Ruiter RA, Sifunda S, Wingood G, van den Borne B. Condom use promotion among isiXhosa speaking women living with HIV in the Western Cape Province, South Africa: a pilot study. AIDS Care 2009; 21:817-25.. No significant difference was found for incidence of bacterial vaginosis. Wingood et al. 2929. Wingood GM, DiClemente RJ, Mikhail I, Lang DL, McCree DH, Davies SL, et al. A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: the WiLLOW Program. J Acquir Immune Defic Syndr 2004; 37:S58-67. reported that participants in the intervention group were not significantly less likely to have a Trichomonas infection any follow-up assessment but were significantly less likely to have an bacterial STI (Chlamydia or gonorrhea) at the 12-month follow-up (OR = 0.10; 95%CI: 0.01, 0.70; p = 0.023) and over the entire 12 months (OR = 0.20; 95%CI: 0.01, 0.06; p = 0.006). These findings indicate that behavioral interventions could be a promising strategy to reduce STI incidence even if it cannot be confirmed through meta-analysis.

Another 5 studies were included in this systematic review but did not provide sufficient data to combine their results, and we present them in a narrative review as follows. One non-randomized trial of an intervention delivered jointly for women and men living with HIV included 45% of female participants in the intervention group and 39% in the comparison 4646. Fisher JD, Fisher WA, Cornman DH, Amico RK, Bryan A, Friedland GH. Clinician-delivered intervention during routine clinical care reduces unprotected sexual behavior among HIV-infected patients. J Acquir Immune Defic Syndr 2006; 41:44-52.. People living with HIV in the intervention group showed a significant reduction (b = 20.51; SE = 0.23, p < 0.05) in unprotected vaginal and anal intercourse and insertive oral sex over a follow-up of 18 months, while these behaviors increased among participants in the comparison arm (b = 0.51; SE = 0.19; p = 0.01). Interventions' effects remained significant when these analyses were performed separately by gender, and the effect was higher in men (p = 0.002) than in women (p = 0.04). In a more conservative measure (unprotected vaginal and anal sex only), authors found a trend toward a reduction in unprotected sex in the intervention group over time (b = 20.42; SE = 0.25; p = 0.09), and a significant increase among standard-of-care control participants (b = 0.61; SE = 0.21; p < 0.01). Similar results were found for both outcomes (broader and conservative) when considering only sexual acts with HIV-negative partners or those with unknown HIV status.

Another RCT 4545. Kalichman SC, Rompa D, Cage M, DiFonzo K, Simpson D, Austin J, et al. Effectiveness of an intervention to reduce HIV transmission risks in HIV-positive people. Am J Prev Med 2001; 21:84-92. included 60 women living with HIV (32%) in the intervention arm and 38 (26%) in the comparison arm. Since the intervention content was tailored to gender, the latter was controlled throughout the analysis, although the results were not presented separately for women and men. The results did not suggest differences between intervention and control groups for number of sexual partners reported at 3 or 6 months follow-up or for rates of unprotected intercourse at the 3-month follow-up. However, there were significant differences between conditions for rates of unprotected sexual acts (OR = 2.2; 95%CI: 0.23, 4.17) and condom use rate at the 6-month follow-up (OR = -17.1; 95%CI: -27.94, -6.26) regardless of the partner's HIV status (OR and 95%CI calculated based on the reported means and standard deviations). Considering sexual practices only with HIV-negative partners, participants in the intervention group showed significantly lower mean rates of unprotected intercourse at 3 months (OR = 0.2; 95%CI: -0.22, 0.62) and 6 months (OR = 0.8; 95%CI: -0.34, 1.94), but no differences were found in the condom use rate (OR and 95%CI calculated based on the reported means and standard deviations). Potential moderators of the intervention effects were examined and no main interactions were found, including participant's gender.

Three other interventions were developed exclusively for women living with HIV and tested in the United States 4242. Echenique M, Illa L, Saint-Jean G, Avellaneda VB, Sanchez-Martinez M, Eisdorfer C. Impact of a secondary prevention intervention among HIV-positive older women. AIDS Care 2013; 25:443-6.), (4343. Jones DL, Weiss SM, Malow R, Ishii M, Devieux J, Stanley H, et al. A brief sexual barrier intervention for women living with AIDS: acceptability, use, and ethnicity. J Urban Health 2001; 78:593-604.), (4444.

In a quasi-experimental study, Jones et al. 4343. Jones DL, Weiss SM, Malow R, Ishii M, Devieux J, Stanley H, et al. A brief sexual barrier intervention for women living with AIDS: acceptability, use, and ethnicity. J Urban Health 2001; 78:593-604. reported that at the 3-month assessment, both groups increased male condom use reaching 40% of protected sexual events in the intervention group (p < 0.001) and 34% in the comparison arm (p < 0.01). Nine months post-intervention, no changes in male condom use were observed, but at both the 3- and 9-month assessments it was not clear if a inter-group analysis had been performed. Using a RCT design and applying only bivariate analysis, Echenique et al. 4242. Echenique M, Illa L, Saint-Jean G, Avellaneda VB, Sanchez-Martinez M, Eisdorfer C. Impact of a secondary prevention intervention among HIV-positive older women. AIDS Care 2013; 25:443-6. found women living with HIV in the intervention group significantly (p < 0.05) reduced inconsistent condom use with all partners from baseline (20%) to 6-month follow-up (9.2%), while women in the control group did not. Finally, another RCT 4444. Teti M, Bowleg L, Cole R, Lloyd L, Rubinstein S, Spencer S, et al. A mixed methods evaluation of the effect of the Protect and Respect intervention on the condom use and disclosure practices of women living with HIV/AIDS. AIDS Behav 2010; 14:567-79. reported that intervention participants were more likely to report condom use at 6 months (AOR = 17.13; 95%CI: 2.96, 99.10; p < 0.01) and 18 months (AOR = 270.04; 95%CI: 24.53, 2,971.94; p < 0.01).

Discussion

A previous systematic review and meta-analysis on behavioral interventions to promote condom use among women living with HIV was not able to demonstrate positive effects 3030.

Considering the need for a more accurate picture of these interventions and their implications for research and decision-making in public health, this study aimed to update and broaden the previous review, including newly published studies and adding a continuous outcome to the pooled analysis.

Concerning consistent condom use (dichotomous outcome), this updated version was unable to identify effects of behavioral interventions even after including other studies, maintaining the result of the original meta-analysis 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844.. As suggested previously 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844., we included a less rigorous outcome in the quantitative syntheses which was intended to identify a reduction in unprotected sexual acts and an increase in the frequency of condom use. Contrary to expectations, the inclusion of a continuous outcome in the updated review did not show positive intervention effects, thus corroborating a growing body of evidence showing low efficacy of behavioral interventios to prevent STI 5454. Macaya Pascual A, Ferreres Riera JR, Campoy Sánchez A. Behavioral interventions for preventing sexually transmitted infections and unintended pregnancies: an overview of systematic reviews. Actas Dermo-Sifiliográficas (English Edition) 2016; 107:301-17.. Even adding some studies in this updated version, we found that data are still limited on the effects of behavioral inteventions on condom use among women living with HIV, and are based on small studies. Thus, our results might change when findings from larger studies are included.

Recent debates have questioned whether biomedical trial methods are the most fitting for assessing behavioral inteventions 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. Behavioral change is a complex and highly context-dependent phenomenon, in contrast to biomedical outcomes which are more objective and easier to measure and respond to - for example, morbidity assessed through blood tests or self-reported symptoms. According to Joint United Nations Programme on HIV/AIDS (UNAIDS) 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014., behavioral change interventions appear to be difficult to evaluate through RCTs and can be erroneously interpreted as ineffective. Still, behavioral change has been responsible for important early declines in HIV incidence in several countries with generalized epidemics 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. Promoting consistent condom use is still a central public health strategy to stop ongoing transmission and avoid negative effects of multiple sexually transmitted infections and/or superinfection in people living with HIV, especially in resource-limited settings where antiretroviral therapy is not widely accessible. The potentially false idea that behavioral interventions do not work could be overcome by carefully examining contextual aspects and designing studies with better methodological quality.

Contrary to findings in the meta-analysis, a different picture emerged when we examined the qualitative syntheses. Different statistical approaches conducted individually by each study showed positive results in all but one intervention 4141. Saleh-Onoya D, Reddy PS, Ruiter RA, Sifunda S, Wingood G, van den Borne B. Condom use promotion among isiXhosa speaking women living with HIV in the Western Cape Province, South Africa: a pilot study. AIDS Care 2009; 21:817-25., either considering consistent condom use and/or reducing the proportion of unprotected sexual acts. These discordant findings are probably related to the intention-to-treat approach assumed in the pooled analyses instead of the per-protocol analysis adopted by most of the studies.

Regarding reduction of STI incidence in women living with HIV, two studies individually mentioned favorable effects of behavioral interventions, but the results could not be pooled in a meta-analysis. STI diagnosis is a critical public health outcome in behavioral intervention trials, since solid evidence backs the biological pathways by which STI facilitate HIV transmission and the negative effects of multiple sexually transmitted infections, especially in women living with HIV 44. Landes M, Thorne C, Barlow P, Fiore S, Malyuta R, Martinelli P, et al. Prevalence of sexually transmitted infections in HIV-1 infected pregnant women in Europe. Eur J Epidemiol 2007; 22:925-36.), (55. McClelland RS, Lavreys L, Katingima C, Overbaugh J, Chohan V, Mandaliya K, et al. Contribution of HIV-1 infection to acquisition of sexually transmitted disease: a 10-year prospective study. J Infect Dis 2005; 191:333-8.), (5353. Lopes F, Buchalla CM, Ayres JRCM. Mulheres negras e não-negras e vulnerabilidade ao HIV/AIDS no estado de São Paulo, Brasil. Rev Saúde Pública 2007; 41:39-46.. We therefore emphasize that even small reductions in STI incidence could favor critical reductions in HIV morbidity and its associated treatment cost. Future behavioral interventions should include STI reduction among their main outcomes in order to better examine their effects.

Another key issue is that few RCTs were found with available data to evaluate the effects of interventions on condom use according to gender. Furthermore, behavioral interventions especially tailored for condom use promotion among women living with HIV are still scarce, which could explain why subgroup analyses could not find differences in intervention effects, based on whether they were exclusively tailored for women. Despite repeated research findings indicating the challenges faced by women living with HIV, more studies are needed to understand how gender-linked factors (e.g., skill-building to negotiate condom use, gender violence, and gender power imbalances regarding economic resources and employment) influence the effectiveness of behavioral interventions to promote condom use 1616. Santos NJ, Barbosa RM, Pinho AA, Villela WV, Aidar T, Filipe EMV. Contextos de vulnerabilidade para o HIV entre mulheres brasileiras. Cad Saúde Pública 2009; 25 Suppl 2:S321-33.), (5454. Macaya Pascual A, Ferreres Riera JR, Campoy Sánchez A. Behavioral interventions for preventing sexually transmitted infections and unintended pregnancies: an overview of systematic reviews. Actas Dermo-Sifiliográficas (English Edition) 2016; 107:301-17.), (5555. Chakrapani V, Newman PA, Shunmugam M, Dubrow R. Prevalence and contexts of inconsistent condom use among heterosexual men and women living with HIV in India: implications for prevention. AIDS Patient Care STDS 2010; 24:49-58.. A recent systematic review of behavioral interventions to improve contraceptive use for family planning among women living with HIV also found limited evidence to compare the interventions' results 5656. Lopez LM, Hilgenberg D, Chen M, Denison J, Stuart G. Behavioral interventions for improving contraceptive use among women living with HIV. Cochrane Database Syst Rev 2013; (1):CD010243.. Among seven included studies, all in Africa, new use of condoms was more likely in women attending services delivering multi-level and integrated care compared to those in routine care in one study. The authors highlighted the lack of effectiveness of delivering standardized information compared to interventions focused on the specific needs and concerns of women living with HIV regarding family planning.

In addition, none of the included studies explicitly mentioned promotion of female condom use, implying that male condoms were the intervention target. This could be seen as an important limitation to such interventions, since male condoms are not a female-initiated contraceptive method. Therefore, interventions involving female condoms should be promoted. We also endorse and advocate interventions to promote pleasant and empowered settings for female and/or male condom use, especially among women living with HIV. Future studies should also try to better elucidate the diversity across women living with HIV, dealing with heterogeneous intervention effects, for example, among women planning to become pregnant, women with casual versus steady partners, women with seroconcordant or serodiscordant partners, and women with multiple partners. Such research would be useful for understanding how specific groups of women could take advantage of interventions to promote condom use as well as for identifying new strategies for designing interventions.

We recommend that behavioral interventions focusing on condom use promotion among women living with HIV could have greater public health impact if they were part of broad positive prevention programs delivered with a gender perspective (including women-initiated prevention options) and developing actions that involve male partners, family planning counseling, community empowerment, mental health and drug abuse treatment, and safe serostatus disclosure settings 1111. Weeks MR, Zhan W, Li J, Hilario H, Abbott M, Medina Z. Female condom use and adoption among men and women in a general low-income urban U.S. population. AIDS Behav 2015; 19:1642-54.), (5555. Chakrapani V, Newman PA, Shunmugam M, Dubrow R. Prevalence and contexts of inconsistent condom use among heterosexual men and women living with HIV in India: implications for prevention. AIDS Patient Care STDS 2010; 24:49-58.. As seen in the qualitative syntheses, few studies included issues beyond sexual risk behavior and none approached family planning or included women's partners. We agree that without addressing social and cultural norms that shape sexual behaviors, opportunities for individual-level behavioral change are limited 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. A new approach to assessment of interventions' effect on condom use in women living with HIV should thus include mediator and moderator factors that assess broad social norms and diversified cultural contexts where sexual practices take place as well as access to specialized and primary healthcare services.

The review process was minimally biased since searches were not restricted by language and included a comprehensive search of databases, conference proceedings, and trials registers as well as contact with experts. The same search strategy and inclusion criteria were applied in both versions. Still, the present systematic review has some limitations that need to be examined. The review's first version had a specific protocol 3030. Carvalho FT, Goncalves TR, Faria ER, Shoveller JA, Piccinini CA, Ramos MC, et al. Behavioral interventions to promote condom use among women living with HIV. Cochrane Database Syst Rev 2011; (9):CD007844. while the present version did not, which could introduce bias. Even so, some of the analyses in the present version were included in the original protocol (e.g., subgroup analysis) as well as in the discussion of results in the first review (e.g., inclusion of a continuous outcome). In addition, some eligible studies 4242. Echenique M, Illa L, Saint-Jean G, Avellaneda VB, Sanchez-Martinez M, Eisdorfer C. Impact of a secondary prevention intervention among HIV-positive older women. AIDS Care 2013; 25:443-6.), (4343. Jones DL, Weiss SM, Malow R, Ishii M, Devieux J, Stanley H, et al. A brief sexual barrier intervention for women living with AIDS: acceptability, use, and ethnicity. J Urban Health 2001; 78:593-604.), (4444. Teti M, Bowleg L, Cole R, Lloyd L, Rubinstein S, Spencer S, et al. A mixed methods evaluation of the effect of the Protect and Respect intervention on the condom use and disclosure practices of women living with HIV/AIDS. AIDS Behav 2010; 14:567-79.), (4545. Kalichman SC, Rompa D, Cage M, DiFonzo K, Simpson D, Austin J, et al. Effectiveness of an intervention to reduce HIV transmission risks in HIV-positive people. Am J Prev Med 2001; 21:84-92. lacked data for inclusion in the meta-analyses, which may have affected the effect size estimates.

Most of the studies were based in clinics where participants were receiving regular HIV care and do not accurately reflect women living with HIV as a whole. No study included in the review had an adequate number of female participants, emphasizing the importance of further research with larger female sample sizes. Meta-analysis also assumes that interventions are sufficiently similar to be combined, while behavioral interventions entail some dissimilarity, which makes it more difficult to propose strict recommendations. Finally, condom use is a multi-causal outcome demanding multimodal and multilevel interventions 1818. Joint United Nations Programme on HIV/AIDS. Social and behaviour change programming. Geneva: Joint United Nations Programme on HIV/AIDS; 2014.. Evaluating behavior change interventions requires understanding how individuals perceive HIV risk and the ability to protect themselves, including knowledge of the available choices.

After assessing data on interventions in female participants following participation in behavioral interventions, we were unable to identify either increases in consistent condom use or reduction in unprotected sex among women living with HIV. In order to capture intervention effects on condom use among women, we strongly recommend multi-method evaluations involving HIV incidence modeling, meta-analyses, and surveys on behavioral and service utilization trends, as well as ethnographical and qualitative clinical trials.
