A Profile of Sexually Active Male Adolescent High School Students in Lima, Peru

To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%). Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.


Introduction
Sexuality-related problems, such as sexually transmitted diseases (STDs), including Acquired Immunodeficiency Syndrome (AIDS), and unintended pregnancies (UIPs) are issues of worldwide concern (CDC, 1992) and particularly in developing countries such as those of South America and the Caribbean.A number of population-based surveys document that adolescents initiate sexual relations at an early age without adequate use of contraception (Morris, 1988;ENJOVEN, 1992;ENDES, 1997).In Latin America, adolescents' level of knowledge about AIDS is high (80%-90%); however, many adolescents continue to feel that they are not personally vulnerable when they have sexual relations (CDC, 1992;Morris, 1994).The spontaneous nature of their initial sexual experience is reflected in the finding that one of the most important reasons for not using contraceptives is because they did not expect to engage in sex (ENJOVEN, 1992).Similar findings are documented in American adolescents with a co-occurrence of other health risk behaviors, such as drug and alcohol use (Weisman, 1989;Resnick et al., 1997;Brener & Collins, 1998).
In Peru, adolescents are also at risk of experiencing the negative consequences of their unprotected sexual relations (Loli et al., 1987;Wulf & Singh, 1991;ENDES, 1992).An important knowledge gap exists in Latin America as a result of the lack of systematic information about the participation and roles of adolescent males in sexual and contraceptive decisionmaking.This information is necessary in order to achieve a reduction in the high incidence of STDs and UIPs in both Latin America and the United States (Dryfoos, 1988;Edwards, 1994;Moore & Driscoll, 1997).Thus, while there are no data available about UIPs fathered by male adolescents and STDs, among female adolescents ages 15-19 (representing 21% of all reproductive-age women in Peru), the fertility rate is 55/1,000 women in urban areas and 139/1,000 in rural areas.Although birth rates are high, 97% of reproductive-age women know or have heard about at least one contraceptive method.However, there exists a substantial gap between knowledge and contraceptive use.For example, only 31% of sexually active adolescents have used a modern contraceptive method.The majority of adolescent women (53%) also expressed that they wanted to have a child in the next two years or beyond this period (ENDES, 1997), thus perhaps decreasing the likelihood of seeking contraceptive protection.In addition, social stigma related to adolescent sexual activity is often associated with contraceptives, resulting in additional barriers in seeking sexual and reproductive health care, since many adolescents hope to deny their sexual activity precisely by avoiding the contraceptive method which symbolizes their behavior (Aral, 1992;Brunham & Embree, 1992;Lande, 1993).
The purpose of this study was to document the level of knowledge and attitudes regarding sexuality and sexual practices among male adolescent students attending the third and fourth secondary school grades (equivalent to ninth and tenth grades in United States) in four high schools in Lima, Peru.

Research design and methods
An anonymous, self-administered survey was completed by students ages 12-19.The survey took approximately one hour to complete and required the signed consent of their parents and school administrators.From a pool of 12 eligible schools in an urban school district, four of these were randomly selected because they met overall criteria for participation, including similar mixture of low-income students, school size, and similar numbers of students who had been referred for health services by school administrators.
The adolescent male questionnaire was comprised of a 50-item instrument concerning six areas: 1) sociodemographic information; 2) family characteristics; 3) personal activities; 4) knowledge and attitudes regarding sexuality; 5) sexual experience; and 6) contraceptive use.The data were gathered as a part of a larger project to develop an intervention model entitled "Prevention of Sexual Risk Behaviors: A School-Based Sex Education Intervention" which was implemented by the Instituto de Estudios de Población de la Universidad Peruana Cayetano Heredia from April 1995 to December 1996, funded by the Ford Foundation.The study variables were: • Sociodemographic information: age, grade, repeated grade, religion.
• Family characteristics: number of persons living at home, type of persons living at home, parents' marital status, parents' schooling, parents' occupations.
• Personal activities and frequency: sports, seeing friends, going to parties, seeing relatives, viewing pornographic videos or magazines, and alcohol, tobacco, and drug use.• Sexuality a) Information: with whom they talk about sexuality.
b) Knowledge: self-rating of level of knowledge.
c) Attitudes: preventing AIDS by use of protection when having sex; a child would be an obstacle to continuing studies; would be impossible to say no to having sex; can control sexual desire; it is difficult to become accustomed to using a condom.d) Hypothetical situations: it is possible to: acquire an STD; become infected by HIV; get someone pregnant.
e) Couple relationships and sexual experience: having had a girlfriend; number of girlfriends; sexual attraction for and contact with males, females, or both; reasons for having sex; age at first ejaculation; age at first sexual intercourse; how long since last sexual intercourse.
f ) Use of contraceptives and pregnancy experience: willingness to: use condoms; attend family planning center; have anal sex; reasons for not using a condom; perception of peers who have had sex; perception of peers who have used contraception.Used contraception in first sexual intercourse; type of contraceptive used.Last sexual intercourse: type of contraceptive.Ever gotten someone pregnant; fathered a child.
Age categories were defined statistically in order to weigh the cells, with early adolescence defined as 12 to 14, middle as 15, and late adolescence as 16 to 19 years old.These breakdowns reflect the age groups participating in this study and the pool of participants.Sexually active was defined by whether the teen had ever had sex.A logistic regression analysis was performed with sexually active as the dependent variable in order to create a profile of sexually active male adolescents.The independent variables were those with a significant OR equal to or larger than 1.5 in the bivariate analysis.These variables were fitted in a logistic regression model in order to identify the variables most predictive of sexually active males.

Results
A total of 1,020 surveys were administered in the selected schools, with 991 (97%) of the sample available for analysis.The remainder were eliminated because surveys were incomplete.

Family characteristics
The mean number of persons who lived in the household was 8 ± 5.4, with a median of seven (n = 885, range 1-28).The majority of students, 74.7% (n = 731/979), lived with both parents, with or without siblings, and with or without other relatives; 80.8% (n = 788/975) of their parents were married or lived together.As for educational level of parents, 58.3% (n = 561/962) of mothers and 69.4% (n = 648/934) of fathers had completed high school.The majority of mothers, 71% (n = 572/804), worked in the home.Almost half of fathers (49%) were either employed, merchants, or professionals; 47% (n = 332/706) were either farmers, factory workers, or had other occupations, such as carpenters or bricklayers; only 4% (n = 28) were unemployed or retired.
When asked to rate their level of knowledge regarding sexuality and contraceptives, 79% stated that they had either an average or high degree of knowledge (63.4%, n = 621/980, and 15.6%, n = 153, respectively); 21% stated that they knew "little" or "nothing" in their self-ratings of knowledge (19.9%, n = 195 and 1.1%, n = 11 respectively).However, their perceptions regarding their level of knowledge were inconsistent with the factual findings as measured by their correct answers to 20 basic questions.Results showed that 66.9% of the sample provided ten or more correct answers, with a mean score of 10.6 ± 3.3 (n = 985, range 0-18 and median of 11).
A majority of respondents, 77.3% (n = 731/ 946), expressed an interest in "learning how to prevent AIDS", while 88.7% (n = 840/947) indicated that they "would protect themselves when they have sexual relationships".In part, the latter response reflects the fact that 64.1% (n = 609/950) indicated that "a child at this moment would be an obstacle to completing their studies".Of the group, 58.4% (n = 550/942) answered that if faced with the opportunity to have sex, "they could decline having sexual relationships", while 70.6% (n = 676/958) expressed that "they can control their sexual desires".Almost a third of students (29.2%, n = 276/945) expressed that if they were to have sex "it would be difficult to use a condom", while another third (30.5%, n = 288) indicated that they did not know what they would do.
In a series of hypothetical situations providing students with an opportunity to indicate their risk perceptions regarding "whether it is possible" to acquire a STD, to be infected with HIV, and to get someone pregnant, the majority of students indicated that they did not know if they were vulnerable or indicated that they were not at risk of STDs (34%, n = 323/946), HIV (61.8%, n = 584/945), or pregnancy (55.5%, n = 530/954).However, sexually active adolescent boys were more likely to indicate their self-perceived risk of acquiring an STD and getting a girl pregnant.

Sexual experience
The majority of respondents had had a girlfriend (73.5%, n = 706/961) and the mean number of relationships was 3.8 ± 3.6 (n = 580, range 1-21 and median of 3).Most respondents indicated that they were attracted to the opposite sex (88.6%, n = 851/960), while 5.7% disclosed that they were attracted to males or to both males and females.The majority of students reported that they had had a heterosexu-al contact (57.8%, n = 544/941) and 6.5% reported that they had had a sexual contact with a male or with both males and females.
First coitus had been with a female friend, girlfriend, or relative in 82.2% (n = 327/398) of the cases, while 17.8% had been with a casual acquaintance or prostitute.Although many of the adolescent males had initiated sexual relations, 39.5% (n = 162/410) had had their last act of sexual intercourse during the previous year, and the pattern of partner choice appeared to be consistent across time, i.e., girlfriend, female friend, or relative in 82.4% of cases (n = 324/393) and the remainder (17.6%, n = 69) with a casual acquaintance or prostitute.
Students were able indicate their reasons for being involved in a sexual relationship; 68.4% (n = 611/894) indicated that their "fear of losing their partner, to get closer to their partner, if their partner had asked to have sex, for love, if both of them decided to have sex, or both of them are prepared" as the principal reasons for being in a sexual relationship.The remaining 31.6% of students mentioned "for pleasure, because it is fun, because of peer pressure, in order to know how it feels, because men do it, or to satisfy bodily needs" as their motivation to be in a sexual relationship.

Contraceptive use
Facing the possibility of having sexual relationships, 87.7% (n = 822/937) indicated that they would use a condom and 80% (n = 722/902) would seek information from a family planning center.Perhaps reflecting a concern regarding pregnancy, a large proportion of students indicated that they would have "anal sex" (32.5%, n = 279/859) or that they did not know what they would do (27.2%,n = 234).Although students expressed that they would likely use a condom, a clear majority of them (73.6%, n = 644/875) provided a number of reasons why they would not use protection: expense, reduction in pleasure, condoms were seen as being used only by adults, as ineffective, or dangerous to their health.The remainder (26.4%) indicated that they would use a condom.
Perceptions regarding peers' experience with sex was also documented: nearly half of the sample (42.5%, n = 412/970) perceived that Cad.Saúde Pública, Rio de Janeiro, 16(3):733-746, jul-set, 2000 many of their male peers had already had sex.Only a low proportion of the sample (19%, n = 185/974) perceived that many of their peers use condoms.
Contraceptives had been used in the first coitus by 32.1% (n = 126/392) of the sexually active males, increasing to 37.5% (n = 156/416) during their most recent sexual intercourse.Condoms were the most common birth control method used: 78% (n = 85/109) of students stated that they had used a condom in their first sexual experience and 84.1% (n = 106/126) in the most recent sexual intercourse.
A small number of students reported that they had ever gotten a girl pregnant (7.7%, n = 31/401); of this number, 27.8% (n = 5/18) had fathered a child, 13 girls had miscarried, and there was no information available on the remaining 13 sexual partners.

Bivariate and multivariate analysis
All variables were crossed with age groups in order to observe if there were any differences by age.The results show differences as age increases (Table 2).A larger number of girlfriends at earlier ages, younger age at first ejaculation, and younger age at first coitus were found to be associated with age.
"Sexually active" was analyzed as a dependent variable, and statistically significant differences were noted among those who were sexually active and those who were not.As shown in Tables 3 and 4, those who had repeated a grade, lived with one parent only, smoked tobacco, drank alcohol, or used drugs frequently, and/or had more girlfriends were more likely to be sexually active.Logistic regression results identified the following variables as the best predictors of sexually active males: repeated a grade, spoke with their girlfriends regarding sex, had first ejaculation at an early age, and currently had a girlfriend (Table 5).

Discussion
Results from this study document a number of biological, social, and contextual factors which appear to be associated with sexual activity among Latino males living in Peru.Study results clearly show a relationship between a male's age, social and sexual maturation, and level of sexual and contraceptive knowledge.Sexual activity was also found to be significantly associated with a variety of activities including use of tobacco, alcohol, and drugs, having had a girlfriend and overall number of girlfriends, age at first ejaculation, and peers who were sexually active.The association between sexual activity and high incidence of failure in school, as reflected in the number of boys who had repeated a school grade, is consistent with other studies of adolescent risk-taking behaviors (Upchurch & McCarthy, 1990;Resnick et al., 1997).Family structure was also seen to bear a relationship to sexual activity.One-fourth of the sample lived in either a single-parent or mixed family; this group was more likely to be sexually active as compared to students living with two parents.Similar patterns have been noted in other research, which predicts earlier sexual debut with non-traditional family structures (McCarthy & Menken, 1989;Kieman & Hobcraft, 1997).Many of the participants were also being raised in low socioeconomic family environments, which were further strained by the pres-sure to support extended family members.These factors may have contributed to the limited contact between parents and their children and fewer opportunities to discuss sex information.It may also reflect parents' ambivalence towards parental messages provided to males in cultures where social norms may support a man's early sexual experience.These findings are somewhat consistent with studies demonstrating that an adequate family context, defined as the presence of both parents and a sense of connectedness within the fami- ly, can prevent poor health and social outcomes, including unintended pregnancies and STD/AIDS, although the research does not demonstrate a relationship between family connectedness and delays in sexual debut (Huerta-Franco et al., 1996;ENJOVEN, 1997;Resnick et al., 1997;Emmons et al., 1998).
Participating in sports (selected as one of the most favorite activities among students) was shown to be a protective factor against early sexual debut.Helping at home was also shown to be a protective factor, perhaps indicative of a connected relationship to the adolescent's family.However, other co-occurring activities, such as going to parties, seeing friends, watching pornographic videos and reading pornographic magazines, and use of tobacco, alcohol, and drugs were found to be associated with being sexually active (McLean & Flanigan, 1993;Capaldi et al., 1996;ENJOVEN, 1997;Califano, 1998;Emmons et al., 1998).These risk behaviors, which have often been noted to co-occur, are cumulative and increase with age (Brener & Collins, 1998).
Regarding information on sexuality, nearly one-half of students reported that they talked with their male friends, 20% with their fathers, and 5.9% with their teachers.These findings point to the value of peers and fathers in the transmission of information when there is a good level of interpersonal communication (Gonzalez et al., 1994;Huerta-Franco et al., 1996).In addition, talking about sexuality with peers of both sexes, as well as their girlfriends, was associated with sexual activity.This relationship may reflect increased peer pressure, lack of personal risk perception, and/or because the adolescent had already decided to engage in a sexual relationship (Moran & Corley, 1991;Millan et al., 1995;Capaldi et al., 1996;Alexander & Hickner, 1997).In contrast, speaking with their mothers or relying on themselves for information were found to be protective factors in delaying the onset of sexual activity.This may reflect a closer relationship with a parent who likely would discourage sexual activity and a personal quality of shyness that could also discourage sexual activity.However, the limited reliance on teachers does not bode well for the current state of trust with this potential source of support and information about such crucial topics.In order to assure the implementation of successful programs, it will be imperative to attract teachers who can establish a non-judgment and trusting relationship with their students.
Although the majority indicated that they had an "average" to "high" degree of knowledge regarding sexuality, clearly the level of accurate knowledge is relatively limited (11 correct answers out of 20 questions).While students who felt they had an average or high degree of knowledge tended to have sexual relations, the actual level of knowledge was not found to be associated with sexual activity.High self-ratings of knowledge, rather than their actual levels, were associated with sexual activity, and these findings are somewhat consistent with other studies who found a limited relationship between knowledge and sexual activity (ENJOVEN, 1997;Goldfarb, 1997;Ruusuvaara, 1997).The majority of participants had positive attitudes towards sexual activity and the use of a contraceptive if faced with an opportunity to engage in sexual relations.However, they also expressed ambivalent feelings regarding both sexual and contraceptive behavior.While stating that "it would be difficult to get accustomed to using a condom" and "it would be impossible to say no to having sexual relations", they also often expressed the opposite view: "I would protect myself when I have sexual relations" and "I could control my sexual desire".Thus, there are many conflicting or ambivalent attitudes and beliefs that influence sexual risk-taking behaviors that need to be considered in developing effective interventions (Hodges et al., 1992;Leland & Barth, 1992;Huerta-Franco et al., 1996;ENJOVEN, 1997).
Although the majority of respondents indicated that they would be willing to use a condom if they wanted to prevent a pregnancy and others indicated that they would be willing to seek information in a family planning center before they became sexually active, bridging intentionally into action is still evasive.In part, this reflects a belief, held by 40% of the participants, that it is the female partner who must protect herself against pregnancy and STDs.Fully one-third of participants reported that they would have anal sex rather than use a condom (McGuire et al., 1992;Langille et al., 1994;Witwer, 1997).
Two-thirds of students reported that they had had their first ejaculation at 13 years of age.Biological development has been associated with earlier exposure to sexual activity and having gotten someone pregnant (Halpern et al., 1993).There is also an increased probability of acquiring an STD.Furthermore, many adolescents did not see themselves as vulnerable to negative consequences, based on the high percentages of adolescents who did not know or did not believe that it was possible for them to get an STD, become infected by HIV, or get someone pregnant.Similar findings have been observed among adolescents from other South American countries (Morris, 1988;Milan et al., 1995), as well as in the United States (Weisman, 1989;Resnick et al., 1997).These findings may in part relate to lack of risk perception among their peers, adolescent developmental issues pertaining to not understanding the consequences of their actions, and the fact that their risk behaviors have been reinforced by their positive short-term effects (e.g., pleasure or group approval of sexual activity), rather than more immediate negative consequences (e.g., a pregnancy scare) (Hunter & Schaechner, 1992).
Almost half of male students had had sex, with early age at sexual debut.These findings are consistent with data from several population-based surveys conducted in South America and the Caribbean, in which 21% to 63% of respondents had had premarital sexual experience, with a mean age of 15 years for males (Morris, 1988;CDC, 1992;Walrond et al., 1993;ENJOVEN, 1997).
These findings further reinforce the need for specifically targeting males when they are young and creating tailored, gender-specific prevention strategies aimed at modifying attitudes and risk behaviors.Such interventions have been found to be successful in modifying male behavior in other settings, resulting in an incremental use of condoms over time (Strunin & Hingson, 1987;Hingson et al., 1990;Witwer, 1997).Such efforts may be especially challenging with these adolescents, because only onefourth of students expressed their willingness to use a condoms.Many participants gave multiple reasons for not using condoms, demonstrating the strong feelings that must be overcome to increase successful condom use among this population group.For example, the majority expressed the opinion that condoms decrease sexual pleasure (Hingson et al., 1990).Nevertheless, significant changes in condom use have been shown as they have become more widely accepted both for protection against STDs and HIV/AIDS and for preventing unintended pregnancy (Kegeles et al., 1988;Pleck et al., 1993;Millan et al., 1995;Witwer, 1997).
Half of students believed that "many of their male friends have already had sex" and the majority believed that "few or none had used a condom".These perceptions are important to consider insofar as they place additional pressure on the male.They also have implications for developing interventions aimed at adolescents and helping to substantiate that the numbers of sexually active students may be far less and the Impossible to say no to having sex 0.8 0.55-1.17CI = confidence interval.
use of contraceptives, particularly condoms, may be significantly higher than imagined by the youth (Lauritsen & Swicegood, 1997).Some of the perceptions regarding contraceptive use may in fact be accurate, as reflected in the low reported use of contraceptives in both the first and most recent acts of sexual intercourse.Despite the ambivalence regarding condom use, the majority of those who used contraceptives relied on this method for protection.This clearly points to the need to address efforts to expand and improve programs which lead adolescents to increase their sexual and contraceptive knowledge and establish the correct and consistent use of condoms among sexually active male adolescents.
This study has some design limitations, so that the findings can only be generalized to those male adolescent students with similar characteristics.In addition, we should consider the reliability of responses and potential under-reporting of sexual activity, given that data were collected in school settings.Finally, cau-tion is necessary in interpreting the "do not know" responses, which may reflect either not knowing what they would do under different circumstances or not knowing anything at all about the subject.
As documented by this profile of sexually active male adolescent students, interventions should be tailored to fit this import age/gender group.We must also pursue strategies that reach males before they become sexually active.Strategies are needed to improve established education programs on sexuality and to make condoms and other contraceptive methods more readily available, as well as to reinforce active involvement by males in contraceptive decision-making.Perhaps most importantly, programs should focus on changing underlying, often contradictory and ambivalent, sexual attitudes and risk-taking behaviors, as well as preventing the co-occurrence of risk behaviors, such as reducing alcohol and drug use along with sexual behavior in order to promote the norm of responsible sexual activity.
