ABSTRACT Objectives: To determine the prevalence of metabolic syndrome (MetS) and its associated factors in a group of HIV-infected middle-aged women. Methods: Cross-sectional study including 273 HIV-infected climacteric women of 40-60 years of age under care in two HIV outpatient reference centers in Brazil. Metabolic syndrome diagnosis was based on 2006 International Diabetes Federation criteria. Sociodemographic, clinical and behavioral factors were evaluated as well as HIV infection-related parameters. Results: Mean age was 47.7 years; 59.1% of women were premenopausal, 91% were on antiretroviral therapy. Current CD4 count was >500 cells/mm3 in 61.7%, current viral load undetectable in 76.9% of women, and a quarter had previous diagnosis of aids. The prevalence of metabolic syndrome in the subgroup of menopausal women was 46.9%. Univariate analysis showed an association between metabolic syndrome and age ≥50 years (p = 0.002), schooling <8 years (p = 0.003), post-menopause (p < 0.001), body mass index (BMI) >25 kg/m2 (p < 0.001), and FSH ≥40 mIU/mL (p = 0.002). In the multivariate analysis only increased BMI (PR = 1.09; 95% CI: 1.05-1.13; p < 0.001) and FSH levels ≥40 mIU/mL (PR = 1.66; 95% CI: 1.14-2.40; p = 0.008) maintained statistical significance. There was no association between PI use or any other factor related to HIV-infection and MetS in any of the analyses performed. Conclusion: High BMI and FSH levels compatible with menopause were the only factors associated with MetS in these middle aged HIV-infected women. In the context of well-controlled, early treated HIV infection, traditional rather than HIV-related factors were associated with MetS.

FUNDAMENTO: A menopausa pode levar a alterações na saúde feminina, com mudanças no estado oxidativo de mulheres pós-menopausadas, para as quais são limitadas as informações relativas à influência da hormonioterapia (HT) sobre as atividades das enzimas antioxidantes. OBJETIVO: Avaliar a influência da HT sobre a atividade da catalase, concentrações de lipídeos e lipoproteínas, proteína de transferência de colesteril éster, substâncias reativas ao ácido tiobarbitúrico, nitratos, proteína C-reativa ultrassensível e espessura da carótida em mulheres pós-menopausadas. MÉTODOS: Foram alocadas 94 mulheres para um de quatro grupos com ou sem HT. O último grupo foi subdividido em mulheres sendo tratadas com estrógeno e outras com estrógeno mais progestágeno. Foram realizadas medidas de parâmetros bioquímicos plasmáticos e da espessura da íntima-média da carótida. RESULTADOS: A HT antagonizou a redução na atividade da catalase após a menopausa, mas não teve efeito sobre os níveis da proteína de transferência de colesteril éster, substâncias reativas ao ácido tiobarbitúrico, peróxido lipídico, nitrato e proteína C reativa ultrassensível, nem sobre a espessura da íntima-média da carótida. A análise multivariada mostrou que a HT baseada em estrógeno atenuou a relação entre os fatores de risco cardiovasculares e a espessura da íntima-média da carótida comum. CONCLUSÃO: Este estudo mostra que a HT em mulheres pós-menopausadas produz efeitos antioxidantes e antiateroscleróticos benéficos por melhorar as concentrações séricas de lipídios e lipoproteínas, aumentar a atividade da catalase sérica e atenuar a associação entre os fatores de risco cardiovasculares e a aterosclerose precoce.

BACKGROUND: Menopause can lead to alterations in women's health, with changes in the oxidative status of postmenopausal women in whom information regarding the influence of hormone therapy (HT) on antioxidant enzyme activities is limited. OBJECTIVE: To evaluate the influence of HT on catalase activity; concentrations of lipids and lipoprotein, cholesteryl ester transfer protein, thiobarbituric acid-reactive substances, nitrates, high-sensitivity C-reactive protein and carotid thickness in postmenopausal women. METHODS: Ninety-four consecutive women were allocated to one of four groups, without HT and with HT. The latter group was subdivided into women using estrogen and those using estrogen plus progestogen therapy. Plasma biochemical parameters and common carotid intima-media thickness measurements were performed. RESULTS: HT antagonized the decrease in catalase activity after menopause, but had no effect on the levels of cholesteryl ester transfer protein, thiobarbituric acid-reactive substances, lipid peroxide, nitrate, high-sensitivity C-reactive protein, or on the common carotid intima-media thickness. Multivariate analysis showed that estrogen-based HT attenuated the relationship between cardiovascular risk factors and the intima-media thickness of the common carotid. CONCLUSION: This study indicates that HT in postmenopausal women produces beneficial antioxidant and anti-atherosclerotic effects by ameliorating the plasma lipid and lipoprotein profiles, increasing plasma catalase activity and attenuating the association between cardiovascular risk factors and early atherosclerosis.

OBJECTIVE: To evaluate the prevalence of sexual dysfunction and its associated factors in middle-aged women with 11 years or more of formal education. METHODS: A cross-sectional, population-based study was carried out using an anonymous, self-response questionnaire. A total of 315 Brazilian-born women, 40-65 years of age with 11 years or more of schooling, participated in the study. The instrument used in the evaluation was based on the Short Personal Experiences Questionnaire. Sexual dysfunction was calculated from the mean score of sexual responsiveness (pleasure in sexual activities, excitation and orgasm), frequency of sexual activities and libido. Sociodemographic and clinical factors were evaluated. Poisson multiple regression analysis was carried out and the prevalence ratios with respective 95% confidence intervals (95%CI) were calculated. RESULTS: The prevalence of sexual dysfunction was 35.9% among our study population. Multiple regression analysis showed that sexual dysfunction was positively associated with older age (prevalence ratios=1.04; 95%CI:1.01-1.07) and with the presence of hot flashes (prevalence ratios=1.37; 95%CI:1.04-1.80). Having a sexual partner (PR=0.47; 95%CI:0.34-0.65) and feeling well or excellent (prevalence ratios= 0.68; 95%CI: 0.52-0.88) were factors associated with lower sexual dysfunction scores. CONCLUSIONS: Sexual dysfunction was present in more than one-third of women that were 40-65 years of age with 11 years or more of formal education. Within that age group, older age and hot flashes were associated with higher sexual dysfunction scores, whereas feeling well and having a sexual partner were associated with better sexuality.

Comparar o conhecimento sobre DST/AIDS e avaliar fatores associados ao conhecimento adequado e ao uso consistente do preservativo masculino, em adolescentes de escolas públicas e privadas do Município de São Paulo. Participaram 1.594 adolescentes entre 12 e 19 anos, de 13 escolas públicas e 5 privadas, que responderam um questionário sobre DST/AIDS e uso de preservativo. Calcularam-se as razões de prevalência com intervalo de confiança de 95%. O escore de conhecimento sobre DST teve o ponto de corte equivalendo a 50% de acerto. Os testes estatísticos foram qui-quadrado e Wilcoxon-Gehan. Realizou-se regressão múltipla de Poisson. O uso consistente de preservativo foi 60% nas escolas privadas e 57,1% nas públicas (p > 0,05) e esteve associado ao sexo masculino e menor nível sócio-econômico. O sexo feminino, maior escolaridade, escola privada, cor branca e estado marital solteiro associaram-se ao maior conhecimento sobre DST. Os adolescentes de escola pública e privada apresentam conhecimento adequado sobre prevenção de DST, entretanto esse conhecimento não determina adoção de atitudes efetivas de prevenção. Programas de conscientização sobre DST/AIDS devem ser ampliados visando minimizar as vulnerabilidades.

This study aimed to compare knowledge about STD/AIDS and identify the factors associated with adequate knowledge and consistent use of male condoms in teenagers from public and private schools in the city of São Paulo, Brazil. We selected 1,594 adolescents ranging 12 to 19 years of age in 13 public schools and 5 private schools to complete a questionnaire on knowledge of STD/AIDS and use of male condoms. Prevalence ratios were computed with a 95% confidence interval. The score on STD knowledge used a cutoff point corresponding to 50% of correct answers. Statistical tests were chi-square and Poisson multiple regression. Consistent use of male condoms was 60% in private and 57.1% in public schools (p > 0.05) and was associated with male gender and lower socioeconomic status. Female gender, higher schooling, enrolment in private school, Caucasian race, and being single were associated with higher knowledge of STDs. Teenagers from public and private schools have adequate knowledge of STD prevention, however this does not include the adoption of effective prevention. Educational programs and STD/AIDS awareness-raising should be expanded in order to minimize vulnerability.

OBJETIVO: Comparar a qualidade de vida de mulheres após a menopausa usuárias e não usuárias de terapia de reposição hormonal (TRH). MÉTODOS: Realizou-se um estudo de corte transversal com mulheres na pós-menopausa, com idade entre 40 e 65 anos, menopausadas há no máximo 15 anos. Consideraram-se como usuárias de TRH aquelas que faziam uso dessa terapia há pelo menos seis meses, e não usuárias aquelas que não fizeram uso dessa terapia nos últimos seis meses. Foram incluídas no estudo 207 mulheres: 106 usuárias e 101 não usuárias de TRH. Avaliaram-se as características sociodemográficas, clínicas e comportamentais. Aplicou-se o Índice de Kupperman para avaliar a intensidade dos sintomas climatéricos, e o questionário Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) para avaliação da qualidade de vida. Na análise dos dados utilizaram-se os testes t de student, Qui-quadrado, exato de Fisher e Mann-Whitney. RESULTADOS: As usuárias de TRH apresentaram média etária de 52,6±4,9 anos e as não usuárias de 54,3±4,7 anos (p=0,01). Houve diferença estatisticamente significativa em relação ao estado marital (p=0,04). As usuárias relataram menor freqüência de sintomas climatéricos de intensidade moderada e acentuada (p=0,001). Dos oito domínios de qualidade de vida avaliados, apenas a vitalidade apresentou escore abaixo de 50 (45) para os dois grupos. Não houve diferenças entre os grupos em relação aos componentes do SF-36. CONCLUSÕES: As mulheres na pós-menopausa usuárias e não usuárias de TRH apresentaram boa qualidade de vida. Não houve diferenças entre usuárias e não usuárias de terapia hormonal.

OBJECTIVE: To compare the quality of life in postmenopausal women who were users and non-users of hormone replacement therapy (HRT). METHODS: A cross-sectional study was conducted on postmenopausal women aged between 40 and 65 years, who had been menopausal for up to 15 years. Women considered HRT users were those who had undergone this type of treatment for at least six months. Non-users of HRT were those who had not received this type of treatment during the last six months. Two hundred and seven women were included in the study: 106 users and 101 non-users of HRT. Sociodemographic, clinical and behavioral characteristics were assessed. The Kupperman Menopausal Index was applied to rate the intensity of climacteric symptoms and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) was applied to assess women's quality of life. For data analysis, a Student's t test, a chi-square analysis, a Fisher's exact test and a Mann-Whitney test were used. RESULTS: The mean age of HRT users was 52.6 ± 4.9 years and the mean age of non-users of HRT was 54.3 ± 4.7 years (p=0.01). There was a statistically significant difference regarding marital status (p=0.04). HRT users reported a lower frequency of moderate and severe climacteric symptoms (p=0.001). Of the eight quality of life domains evaluated, only vitality scored below 50 (45) in both groups. There were no differences between groups regarding the SF-36 components. CONCLUSIONS: Postmenopausal women who were users and non-users of HRT presented a good quality of life. There were no differences between users and non-users of hormone therapy.
