Resumo O presente estudo objetivou verificar a associação entre aspectos psicossociais (capital social) e padrões alimentares em mulheres adultas. Realizou-se um estudo transversal, de base populacional, com uma amostra representativa de 1.128 mulheres, de 20 a 69 anos de idade, residentes na área urbana do município de São Leopoldo, Rio Grande do Sul, em 2015. Os padrões alimentares foram identificados com base na frequência de consumo alimentar e classificados em: saudável (frutas, vegetais e alimentos integrais), de risco (alimentos ultraprocessados) e brasileiro (arroz e feijão), enquanto o capital social foi avaliado por meio de uma escala de eficácia coletiva. Observou-se que 18,9% da amostra foi classificada com alta eficácia coletiva. Após ajuste para potenciais fatores de confusão, observou-se uma probabilidade 44% maior para adesão ao padrão saudável (RP [razão de prevalência] = 1,44; IC95% [intervalo de confiança de 95%]: 1,01-2,03; p = 0,040) e 71% maior para o padrão brasileiro (RP = 1,71; IC95%: 1,18-2,47; p = 0,004) entre as mulheres com um maior nível de eficácia coletiva, quando comparadas às com baixo nível de eficácia coletiva. Assim, este estudo verificou uma relação significativa entre aspectos psicossociais e consumo alimentar em mulheres.

Abstract The present study aimed to verify the association between psychosocial aspects (social capital) and food patterns in adult women. A cross-sectional, population-based study was conducted with a representative sample of 1,128 women, aged 20 to 69 years, living in the urban area of the municipality of São Leopoldo, Rio Grande do Sul, Brazil, in 2015. The food patterns were identified based on the frequency of food intake and classified as: healthy (fruits, vegetables, and whole foods), at-risk (ultraprocessed foods), and Brazilian (rice and beans), while social capital was evaluated using a collective efficacy scale. It was observed that 18.9% of the sample was classified with high collective efficacy. After adjusting for potential confounding factors, a 44% higher probability was observed for adherence to the healthy pattern (PR [prevalence ratio] = 1.44; 95%CI [95% confidence interval]: 1.01-2.03; p = 0.040) and 71% higher for the Brazilian pattern (PR = 1.71; 95%CI: 1.18-2.47; p= 0.004) among women with a higher level of collective efficacy, when compared to those with a low level of collective efficacy. Thus, this study verified a significant relationship between psychosocial aspects and food intake in women.

ABSTRACT Objective: To identify multimorbidity patterns in women in southern Brazil, and its relationship with sociodemographic, lifestyle characteristics, and nutritional status, as well as to explore the main independent risk factor for the identified patterns. Subjects and methods: This is a cross-sectional, population-based study with 1,128 women (20-69 years), southern Brazil. Chronic conditions were identified using the therapeutic and chemical anatomical classification of continuous use of medications. Multimorbidity was assessed as ≥2 or ≥3 chronic conditions to identify dyads and triads. Poisson regression was used to explore risk factors in the different adjustment models. As independent variables evaluated, in addition to sociodemographic characteristics, lifestyle variables were included: consumption of fruits and vegetables, physical activity, alcohol consumption, smoking and nutritional status. Results: Eleven dyads (frequencies between 2.0% and 6.4%) and three triads (frequencies between 1.9% and 2.1%) of morbidities were identified in the study. Aging was related to a higher prevalence of all patterns, and obesity was a risk factor for multimorbidity patterns that contained conditions related to the cardiovascular and metabolic system and mental health. After adjustment, obesity increased the probability of “hypertension + common mental disorders (CMD)” (PR 3.63; 95% CI 1.94-6.78) and “dyslipidemia + CMD” (PR 3.69; 95% CI 1.08-12.65) by more than three times. Conclusion: This study identified common and important diseases in the patterns, associated with a common risk factor, obesity, that must be addressed by public health policies to prevent multimorbidity.

Resumo Introdução As escolhas alimentares podem ser influenciadas por apoio social e capital social. Objetivo Investigar as relações do apoio social e capital social com o consumo alimentar. Método Trata-se de um estudo transversal, de base populacional, com uma amostra aleatória de 1.098 adultos (≥ 18 anos de idade) de uma cidade no Sul do Brasil. O apoio social foi mensurado por meio da escala Medical Outcomes Study (MOS), e o capital social contemplou a avaliação dos indicadores de coesão social, apoio dos vizinhos, controle social informal, eficácia política e ação social. Para o consumo alimentar, utilizou-se de uma escala com base nas orientações do guia alimentar para a população brasileira. Resultados A média de idade da amostra foi de 44 anos (DP[Desvio-padrão] = 15,8), e identificou-se um consumo alimentar adequado em 38,6% (IC95%: 35,7 a 41,5). Após ajuste, observou-se uma probabilidade 40% maior para adoção de consumo alimentar adequado (saudável) entre os indivíduos com maior nível de apoio social (OR = 1,47; IC95%: 1,07 a 2,03), coesão social (OR = 1,40; IC95%: 1,02 a 1,92) e apoio dos vizinhos (OR = 1,45; IC95%: 1,04 a 2,02). Conclusão Os aspectos psicossociais, tanto individual quanto contextual, podem desempenhar um papel importante no consumo alimentar saudável em adultos.

Abstract Background Food choices can be influenced by psychosocial factors. Objective To investigate the relationships between social support and social capital with food consumption. Method This is a population-based cross-sectional study with a random sample of 1098 adults (≥18 years old) from a medium-sized city in southern Brazil. Social support was measured by Medical Outocomes Study (MOS) scale and social capital was assessed by social cohesion, neighbor support, informal social control, political effectiveness, and social action. For the assessment of food consumption was applied a scale based on the food guide for the Brazilian population. Results The mean age of the sample was 44 years (SD [Standard Deviation] = 15.8) and adequate food consumption was identified in 38.6% (95% CI: 35.7 to 41.5). After adjustment, there was a 40% higher probability of adopting adequate (healthy) food consumption among individuals with higher level of social support (OR = 1.47; 95% CI: 1.07 to 2.03), cohesion. social (OR = 1.40; 95% CI: 1.02 to 1.92) and support from neighbors (OR = 1.45; 95% CI: 1.04 to 2.02). Conclusion Both individual and contextual psychosocial aspects can play an important role in healthy food consumption in adults.

Resumo Introdução No Sul do Brasil, a principal causa de mortalidade por neoplasias entre as mulheres está ocupada pelo câncer de mama. O exame clínico anual das mamas está recomendado como medida de rastreamento. Objetivo Investigar a prevalência de não realização do exame clínico de mamas nos últimos 12 meses e fatores associados em mulheres de 20 a 69 anos residentes no município de São Leopoldo/RS em 2015. Método Estudo transversal de base populacional, no qual foram incluídas na análise variáveis demográficas e socioeconômicas. Foram calculadas as razões de prevalência (RP) por regressão de Poisson. Resultados Entre 1.128 mulheres, a prevalência de não realização de exame clínico das mamas foi de 52,6% (IC95%: 51,1-57,2); na análise ajustada, a não realização do exame mostrou-se associada à classe econômica D/E (RP = 1,58; IC95%: 1,16-2,15) e escolaridade de 0 a 4 anos de estudo (RP = 2,16; IC95%: 1,33-3,53). Conclusão As mulheres em situação de vulnerabilidade social apresentaram maior probabilidade de não realização do exame, demonstrando a iniquidade do sistema.

Abstract Background In southern Brazil, the main cause of mortality from cancer among women is breast cancer. Annual clinical breast examination is recommended as a screening measure. Objective To investigate the prevalence of patients that did not perform breast exams in the last 12 months and its associated factors in women aged 20 to 69 years living in São Leopoldo/RS in 2015. Method The present research is a population-based, cross-sectional study; demographic and socio-economic variables were included in the analysis; prevalence ratios (PR) were calculated by Poisson regression. Results Among the 1128 women sampled, the prevalence of not performing clinical breast exams was of 52.6% (95%CI: 51.1-57.2); in the adjusted analysis, not performing clinical breast exams was associated with having a D/E socio-economic status (PR = 1.58; 95%CI: 1.16-2.15), as well as with having an educational level of 0 to 4 years of study (PR = 2.16; 95%CI: 1.33-3.53). Conclusion Women in social vulnerability were more likely to not perform the exams, demonstrating the inequity of the system.

ABSTRACT: Objective: This study aimed to identify the prevalence of multimorbidity and its associated factors in women in southern Brazil. Methods: We conducted a cross-sectional, population-based study with a sample of 1,128 women (age 20–69 years), living in São Leopoldo, southern Brazil. Multimorbidity was defined as two or more chronic conditions measured using the therapeutic and chemical anatomical classification of continuous use medications prescribed by a physician. Poisson regression model with robust variance was used to assess the association between sociodemographic and lifestyle variables and multimorbidity. Results: The prevalence of multimorbidity was 21.7% (95%CI 19.3–24.2), and 26 chronic conditions were identified. A direct linear association was observed with age and income and an inverse association with education. Being unemployed was a risk factor for multimorbidity (PR 1.95; 95%CI 1.51–2.52). Alcohol consumption (moderate or excessive) had a protective effect. Overweight and obese women were 53% (PR 1.53; 95%CI 1.09–2.15) and 76% (PR 1.76; 95%CI 1.27–2.45) more likely to have multimorbidity than eutrophic women. Conclusion: Over 20% of the adult women had multimorbidity, and its occurrence was strongly associated with socioeconomic characteristics, such as fewer years of schooling, higher income, and not having an occupation. The results regarding alcohol consumption are still insufficient to propose a public policy for the prevention of multimorbidity. Excess weight was an independent risk factor and should be addressed in public health policies for the prevention and management of multimorbidity.

ABSTRACT Objective: To investigate the association of dietary patterns, number of daily meals and anthropometric measures among women in age of menopause. Subjects and methods: This was a transversal study with 320 women over 50 years old from Caxias do Sul, Brazil. The outcomes were body mass index (BMI) and waist circumference (WC). Multiple linear regression was performed. Results: Three dietary patterns: regional, fruits and vegetables, and common Brazilian was identified by Principal Component Analysis. After adjustment, higher adoption of the regional dietary pattern was associated with increased BMI (β = 0.56 [CI95% = 0.03-1.08], p = 0.037) and WC (β = 1.28 [CI95% = 0.17-2,55], p = 0.047). The highest number of meals per day (>=5/day) was associated with reduced BMI (β = -1.18 [CI95% = -2.30 to -0.05], p = 0.041) and WC (β = -2.77 [CI95% = -5.41 to -0.13], p = 0.039), and a mid-afternoon snack BMI (β = -2.16 [CI95% = -3.66 to -0.65], p = 0.005) and WC (β = -5.76 [CI95% = -9.29 to -2.23], p = 0,001). The regional dietary pattern was inversely associated with have five or more meals per day (β = -0.51 [CI95% = -0.84 to -0.18], p = 0.002) and have a mid-afternoon snack (β = -0.63 [CI95% = -1.07 to -0.18], p = 0.006). The fruit and vegetables dietary pattern was positively associated with have five or more meals per day (β = 0.35 [CI95% = 0.02-0.69], p = 0.034). Conclusion: The regional dietary pattern has resulted in higher BMI and WC measures and contributes to decreased meals per day, behavior associated with higher anthropometric measures.

Resumo Fundamento A hipertensão é um importante e persistente problema de saúde pública, sendo uma das principais causas de doenças cardiovasculares e mortalidade geral. Objetivos Este estudo buscou verificar a prevalência e os fatores associados à hipertensão arterial sistêmica em trabalhadores da indústria do estado do Rio Grande do Sul, Brasil. Métodos Trata-se de um estudo transversal com dados secundários de 20.792 industriários de 18 a 59 anos de idade. A presença de hipertensão arterial foi determinada a partir da pressão arterial sistólica ≥140mmHg e/ou pressão arterial diastólica ≥90mmHg, ou estar fazendo uso de medicação anti-hipertensiva. Os fatores investigados incluíram características demográficas, socioeconômicas, comportamentais, de estado nutricional e de história familiar. Regressão de Poisson foi utilizada na análise multivariável, adotando-se um p<0,05 como nível de significância. Todas as análises foram estratificadas por sexo. Resultados A amostra incluiu 12.349 homens e 8.443 mulheres com média de idade geral de 32,8 anos (Desvio-padrão=9,8 anos). A prevalência de hipertensão foi de 10,3% (IC95%:9,8-10,7), sendo esta significativamente maior entre os homens do que entre as mulheres (10,9% vs 9,4%;p=0,001). A hipertensão mostrou-se associada à elevação da faixa etária, baixa escolaridade, viver com companheiro, ter sobrepeso ou obesidade, e ter pelo menos um parente com história de hipertensão para ambos os sexos. As mulheres com melhores condições socioeconômicas apresentaram menores prevalências de hipertensão. Conclusões Os principais fatores associados à hipertensão arterial compreenderam características sociodemográficas, nutricionais e de história familiar. Ademais, as condições socioeconômicas demonstraram uma associação com a ocorrência de hipertensão, principalmente entre as mulheres.

Abstract Background Hypertension is a serious and persistent public health problem and is one of the main causes of cardiovascular diseases and general mortality. Objectives This study aimed to verify the prevalence and factors associated with systemic arterial hypertension in workers from the state of Rio Grande do Sul, Brazil. Methods This is a cross-sectional study using the secondary data from 20,792 industry workers from 18 to 59 years of age. The presence of arterial hypertension was determined from systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥ 90mmHg or taking antihypertensive medication. Factors investigated included demographic, socioeconomic, behavioral, nutritional status, and family history characteristics. Poisson regression was used in multivariate analysis, adopting a significance level of p<0.05. All analyses were stratified by sex. Results The sample included 12,349 men and 8,443 women with a mean age of 32.8 years (Standard Deviation = 9.8). The prevalence of arterial hypertension was 10.3% (95% CI: 9.8-10.7), which was significantly higher in men than in women (10.9% vs 9.4%; p = 0.001). Arterial hypertension was associated with increased age, a low level of education, living with a partner, being overweight or obese, and having at least one relative with a history of hypertension for both sexes. Women with better socioeconomic conditions presented a lower prevalence of hypertension. Conclusions The main factors associated with hypertension included sociodemographic, nutritional, and family history characteristics. In addition, socioeconomic conditions showed an association with the occurrence of hypertension, especially among women.

Resumo O objetivo deste estudo é descrever o ambiente alimentar de um município de médio porte do Sul do Brasil e relacionar a disponibilidade de diferentes tipos de comércios de alimentos com características socioeconômicas e demográficas do entorno. Trata-se de estudo ecológico em 45 buffers, de 400m, em São Leopoldo, Rio Grande do Sul. O buffer foi calculado a partir do centróide das residências das mulheres participantes de um projeto de pesquisa maior. Todas as ruas foram percorridas para a identificação dos estabelecimentos de alimentos, que tiveram suas coordenadas geográficas registradas, bem como foram avaliados, através do questionário NEMS (Nutrition Environment Measures Survey in Stores), sobre disponibilidade, preço e qualidade de 108 itens. Os comércios foram classificados em supermercados, mercearias, fruteiras e lojas de conveniência. Os supermercados e as mercearias estavam em maior número nos buffers de menor renda e mercearias mais presentes naqueles de maior tercil populacional. Observa-se relação direta entre escores do NEMS e tercil de renda para supermercados, mercearias e fruteiras e indireta para os mesmos comércios e tercil populacional. A disponibilidade de alimentos saudáveis se mostrou mais elevada em áreas de maior renda e menor número de habitantes, o que sinaliza a necessidade de melhor distribuição dos comércios e variedades de alimentos.

Abstract The scope of this study is to describe the food environment of a medium-sized municipality in southern Brazil and compare the availability of different types of food outlets in neighborhood socioeconomic and demographic environments. An ecological study was carried out in 45 buffers of 400m in São Leopoldo county, RS. The buffer was calculated from the center point of the residences of women participating in a larger research project. All streets were surveyed to identify food stores and record their geographical coordinates, as well as apply the NEMS questionnaire on the availability, price and quality of 108 items. The commercial outlets were classified as supermarkets, grocery stores, fruit stores and convenience stores. Supermarkets and grocery stores were present in higher quantity in lower income buffers and grocery stores were more prevalent in those with higher population tertiles. Another result was a direct relationship between NEMS and tertile income scores for supermarkets, grocery stores and fruit stores, and an indirect relationship for the same stores and population tertile. The availability of healthy food was higher in areas with higher income and lower numbers of inhabitants, indicating the need for better distribution of food stores and availability of varieties of food in the municipality.

RESUMO O objetivo deste estudo foi identificar a prevalência de dor lombar crônica e seus fatores associados em uma população de mulheres. Para isso, realizou-se um estudo transversal, de base populacional, com 1.128 mulheres com idade entre 20 e 69 anos e residentes na zona urbana de São Leopoldo, Rio Grande do Sul. A dor lombar crônica foi avaliada a partir da presença de dor com duração mínima de três meses, e os fatores investigados incluíram aspectos sociodemográficos, comportamentais e antropométricos. Os resultados indicaram uma prevalência de dor lombar crônica de 46,5% (IC95%: 43,6-49,4). Após ajuste, os fatores associados à dor lombar crônica foram: idade, atividade física e estado nutricional. Observou-se uma associação com tendência linear positiva entre idade e dor lombar, assim como uma probabilidade 31% (RP=1,31; IC95%: 1,05-1,64; p=0,02) e 25% (RP=1,25; IC95%: 1,09-1,42; p<0,001) maior de mulheres fisicamente inativas e obesas terem dor lombar, quando comparadas às mulheres fisicamente ativas e com peso corporal normal, respectivamente. Assim, este estudo evidenciou uma elevada prevalência de dor lombar crônica em mulheres, identificando como principais fatores associados a sua ocorrência a idade avançada, a inatividade física e a obesidade.

ABSTRACT This study sought to identify the prevalence of chronic low back pain and its associated factors in a population of women. A cross-sectional population-based study was conducted with 1,128 women aged 20 to 69 and living in the urban area of São Leopoldo, Rio Grande do Sul (Brazil). Chronic low back pain was assessed by the presence of prevailing pain lasting for at least three months, and the investigated factors consisted of sociodemographic, behavioral and anthropometric aspects. The prevalence of chronic low back pain was 46.5% (95%CI: 43.6-49.4). After the adjustment, factors associated with the presence of chronic low back pain were: age, physical activity and nutritional status. We observed an association with a positive linear trend between age and low back pain. Furthermore, physically inactive and obese women presented, respectively, a 31% (PR=1.31; 95%CI: 1.05-1.64; p=0.02) and 25% (PR=1.25; 95%CI: 1.09-1.42; p<0.001) higher probability of presenting low back pain than those with normal body weight. In conclusion, we identified a high prevalence of chronic low back pain in women, and the main associated factors included: advanced age, physical inactivity and obesity.

RESUMEN El objetivo de este estudio fue identificar la prevalencia de lumbalgia crónica y sus factores asociados en mujeres. Se realizó un estudio transversal, poblacional, con 1.128 mujeres de entre 20 y 69 años de edad, residentes en la zona urbana de São Leopoldo, en el estado de Rio Grande do Sul (Brasil). Para caracterizar lumbalgia crónica se evaluó la presencia de dolor durante al menos tres meses, y los factores investigados incluyeron aspectos sociodemográficos, conductuales y antropométricos. Los resultados apuntan una prevalencia de lumbalgia crónica del 46,5% (IC95%: 43,6-49,4). Tras el ajuste, los factores asociados a la lumbalgia crónica fueron: edad, actividad física y estado nutricional. Hubo una asociación de tendencia lineal positiva entre la edad y la lumbalgia, así como una probabilidad del 31% (RP=1,31; IC95%: 1,05-1,64; p=0,02) y del 25% (RP= 1,25; IC95%: 1,09-1,42; p<0,001) mayor de dolor lumbar en mujeres físicamente inactivas y obesas en comparación con mujeres físicamente activas y con peso corporal normal. Este estudio evidenció una alta prevalencia de lumbalgia crónica en mujeres y los principales factores asociados fueron la edad avanzada, la inactividad física y la obesidad.

RESUMO OBJETIVO Identificar fatores associados aos transtornos mentais comuns (TMC) em uma amostra de mulheres adultas no Sul do Brasil. MÉTODOS Em estudo de base populacional composto por 1.128 mulheres, foram investigadas variáveis explicativas demográficas, socioeconômicas, comportamentais e de saúde/doença. Cinco grupos-resposta foram explorados: um grupo com transtornos mentais comuns – ponto de corte 6/7 no Self-Reporting Questionnaire 20 (SRQ-20) – e outros quatro correspondentes aos diferentes clusters encontrados através da técnica de clusterização por classe latente, também a partir do SRQ-20. Esses quatro clusters (baixo, médio-depressivo, médio-digestivo e alto) foram denominados com base nas pontuações médias do SRQ-20 em cada grupo e nos padrões de resposta das variáveis e características fatoriais. O cluster “baixo” compreendeu mulheres com menores escores no SRQ-20 e, portanto, com menor probabilidade de apresentarem TMC. Já o cluster “alto”, com valores médios elevados no SRQ-20, esteve relacionado a maior morbidade psiquiátrica. Utilizou-se a técnica de regressão de Poisson, com comparação entre os achados dos diferentes grupos. RESULTADOS Foram identificadas 10 variáveis como fatores associados aos TMC. Idade, escolaridade, tabagismo, atividade física, percepção de saúde e número de consultas foram as variáveis comuns para as análises com ponto de corte assim como nas baseadas em clusters. Etilismo pesado esteve associado somente quando avaliada a amostra como ponto de corte. Já classe econômica, situação laboral e presença de doenças crônicas estiveram associadas somente quando analisada a amostra por clusters. No cluster “alto”, houve associação significativa com classes econômicas mais baixas (D ou E), tabagismo, inatividade física, presença de doenças crônicas e percepção de saúde negativa. CONCLUSÕES Diferentes fatores associados foram identificados segundo os grupos-resposta considerados. Novos enfoques que possibilitem identificar subgrupos de indivíduos com características e fatores associados específicos poderiam contribuir para um entendimento mais apurado dos TMC, servindo de base para intervenções em saúde.

ABSTRACT OBJECTIVE to identify factors associated with common mental disorders (CMD) in a sample of adult women in Southern Brazil. METHODS This population-based study, composed of 1,128 women, investigated socioeconomic, behavioral and health/disease explanatory demographic variables. Five response groups were explored: one group with common mental disorders – cut-off point 6/7 in the Self-Reporting Questionnaire 20 (SRQ-20) – and four others corresponding to the different clusters found using the latent class clustering technique, also from the SRQ-20. These four clusters (low, medium-depressive, medium-digestive and high) were named (denominated) based on the mean scores in the SRQ-20 in each group and on the response patterns of the variables and factorial characteristics. The “low” cluster comprised women with lower SRQ-20 scores and, therefore less likely to present CMD. The “high” cluster, with high mean values in the SRQ-20, was related to higher psychiatric morbidity. We used the Poisson regression technique to compare the findings of the different groups. RESULTS We identified ten variables as factors associated with CMD. Age, education, smoking, physical activity, perception of health and number of medical appointments were the common variables for the cut-off point and cluster-based analyses. Heavy alcohol use was associated only when the sample was evaluated as a cut-off point. Social class, work situation and existence of chronic diseases were associated only when the sample was analyzed by clusters. There was a significant association in the “high” cluster with lower classes (D or E), smoking, physical inactivity, existence of chronic diseases and negative perception of health. CONCLUSION We identified different associated factors according to the response groups considered. New approaches allowing identification of subgroups of individuals with specific characteristics and associated factors may contribute for a more accurate understanding of CMD and provide the basis for health interventions.

RESUMO OBJETIVO Identificar fatores associados aos transtornos mentais comuns (TMC) em uma amostra de mulheres adultas no Sul do Brasil. MÉTODOS Em estudo de base populacional composto por 1.128 mulheres, foram investigadas variáveis explicativas demográficas, socioeconômicas, comportamentais e de saúde/doença. Cinco grupos-resposta foram explorados: um grupo com transtornos mentais comuns – ponto de corte 6/7 no Self-Reporting Questionnaire 20 (SRQ-20) – e outros quatro correspondentes aos diferentes clusters encontrados através da técnica de clusterização por classe latente, também a partir do SRQ-20. Esses quatro clusters (baixo, médio-depressivo, médio-digestivo e alto) foram denominados com base nas pontuações médias do SRQ-20 em cada grupo e nos padrões de resposta das variáveis e características fatoriais. O cluster “baixo” compreendeu mulheres com menores escores no SRQ-20 e, portanto, com menor probabilidade de apresentarem TMC. Já o cluster “alto”, com valores médios elevados no SRQ-20, esteve relacionado a maior morbidade psiquiátrica. Utilizou-se a técnica de regressão de Poisson, com comparação entre os achados dos diferentes grupos. RESULTADOS Foram identificadas 10 variáveis como fatores associados aos TMC. Idade, escolaridade, tabagismo, atividade física, percepção de saúde e número de consultas foram as variáveis comuns para as análises com ponto de corte assim como nas baseadas em clusters. Etilismo pesado esteve associado somente quando avaliada a amostra como ponto de corte. Já classe econômica, situação laboral e presença de doenças crônicas estiveram associadas somente quando analisada a amostra por clusters. No cluster “alto”, houve associação significativa com classes econômicas mais baixas (D ou E), tabagismo, inatividade física, presença de doenças crônicas e percepção de saúde negativa. CONCLUSÕES Diferentes fatores associados foram identificados segundo os grupos-resposta considerados. Novos enfoques que possibilitem identificar subgrupos de indivíduos com características e fatores associados específicos poderiam contribuir para um entendimento mais apurado dos TMC, servindo de base para intervenções em saúde.

ABSTRACT OBJECTIVE to identify factors associated with common mental disorders (CMD) in a sample of adult women in Southern Brazil. METHODS This population-based study, composed of 1,128 women, investigated socioeconomic, behavioral and health/disease explanatory demographic variables. Five response groups were explored: one group with common mental disorders – cut-off point 6/7 in the Self-Reporting Questionnaire 20 (SRQ-20) – and four others corresponding to the different clusters found using the latent class clustering technique, also from the SRQ-20. These four clusters (low, medium-depressive, medium-digestive and high) were named (denominated) based on the mean scores in the SRQ-20 in each group and on the response patterns of the variables and factorial characteristics. The “low” cluster comprised women with lower SRQ-20 scores and, therefore less likely to present CMD. The “high” cluster, with high mean values in the SRQ-20, was related to higher psychiatric morbidity. We used the Poisson regression technique to compare the findings of the different groups. RESULTS We identified ten variables as factors associated with CMD. Age, education, smoking, physical activity, perception of health and number of medical appointments were the common variables for the cut-off point and cluster-based analyses. Heavy alcohol use was associated only when the sample was evaluated as a cut-off point. Social class, work situation and existence of chronic diseases were associated only when the sample was analyzed by clusters. There was a significant association in the “high” cluster with lower classes (D or E), smoking, physical inactivity, existence of chronic diseases and negative perception of health. CONCLUSION We identified different associated factors according to the response groups considered. New approaches allowing identification of subgroups of individuals with specific characteristics and associated factors may contribute for a more accurate understanding of CMD and provide the basis for health interventions.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor lombar é uma condição comum em mulheres. Além disso, essa população apresenta maior risco de dor crônica. No entanto, os fatores associados à dor lombar crônica ainda são controversos. Assim, este estudo teve como objetivo avaliar os fatores de predisposição associados ao maior risco de dor lombar crônica. MÉTODOS: Foi realizado um estudo transversal de base populacional em uma amostra de 636 mulheres adultas brasileiras com idades entre 20 e 69 anos que relataram sintomas de dor lombar nas últimas duas semanas. O nível de risco de dor lombar crônica foi medido pela versão brasileira validada do escore Subgroups for Targeted Treatment (STarT). RESULTADOS: O risco de dor lombar crônica foi classificado como baixo, médio e alto em 330 (51,9%), 202 (31,8%) e 104 (16,4%) mulheres, respectivamente. Após os ajustes, os principais fatores associados ao maior risco de dor lombar crônica foram: idade de 50 anos ou mais (RC=2,67; IC95%: 1,43-4,96), baixa renda familiar (RC=2,23; IC95%: 1,34-3,72), 4 anos de estudo ou menos (RC=2,17; IC95%: 1,35-3,48), estilo de vida sedentário (RC=2,97; IC95%: 1,59-5,55), tabagismo (RC=1,61; IC95%: 1,07-2,44) e multiparidade (RC=2,84; IC95%: 1,45-5,57). A cor da pele, o estado civil e a obesidade não foram associados a um maior risco de dor lombar crônica. CONCLUSÃO: Este estudo indicou que os fatores de predisposição associados a um maior risco de lombalgia crônica em mulheres incluíram idade avançada, desvantagem socioeconômica, comportamentos de saúde inadequados e multiparidade.

ABSTRACT BACKGROUND AND OBJECTIVES: Low back pain is a common condition in women. In addition to that, women have a higher risk of chronic pain. However, the factors associated with chronic low back pain are still controversial. Thus, this study’s objective was to evaluate the predictive factors associated with a higher risk of chronic low back pain. METHODS: A cross-sectional population-based study was conducted on a sample of 636 Brazilian adult women aged 20-69 years who reported symptoms of low back pain in the last two weeks. The level of risk of chronic low back pain was measured by the validated Brazilian version of Subgroups for Targeted Treatment (STarT) score. RESULTS: The risk of chronic low back pain was classified as low, medium, and high in 330 (51.9%), 202 (31.8%), and 104 (16.4%) women, respectively. After adjustments, the main factors associated with a higher risk of chronic low back pain were: aged 50 years or older (OR=2.67; 95%CI: 1.43-4.96), low household income (OR=2.23; 95%CI: 1.34-3.72), 4 years of education or less (OR=2.17; 95%CI: 1.35-3.48), sedentary lifestyle (OR=2.97; 95%CI: 1.59-5.55), smoking (OR=1.61; 95%CI: 1.07-2.44), and multiparity (OR=2.84; 95%CI: 1.45-5.57). Skin color, marital status, and obesity were not associated with a higher risk of chronic low back pain. CONCLUSION: This study indicates that the predictive factors associated with a higher risk of chronic low back pain in women included advanced aged, socioeconomic disadvantage, poor health behaviors and multiparity.
