Reprodução na juventude: perfis sociodemográficos, comportamentais e reprodutivos na PNDS 2006

OBJETIVO: Analizar características sociodemográficas y de conductas sexual y reproductiva de mujeres jóvenes. MÉTODOS: Estudio poblacional transversal con representatividad nacional sobre el comportamiento sexual, anticonceptivo y reproductivo de 2.991 mujeres de 15 a 20 años en la Investigación Nacional de Demografía y Salud del Niño y de la Mujer (PNDS) 2006. Las jóvenes se clasificaron en tres grupos: iniciaron la vida sexual y se embarazaron antes de los 20 años (grupo A); iniciaron la vida sexual y no se embarazaron antes de los 20 (grupo B) y no iniciaron la vida sexual (grupo C). Mujeres de hasta 25 años se consideraron para el estudio de las tasas de embarazo y de sus consecuencias en la vida. Los análisis estadísticos consideraron los pesos y la planificación del muestreo complejo. La asociación entre dos variables categóricas fue evaluada por la prueba Chi-cuadrado. Para las conductuales, se utilizó el modelo linear global. RESULTADOS: Mujeres del grupo A eran principalmente negras, más pobres y con menor escolaridad. Tuvieron la primera relación sexual más precozmente, comportamiento anticonceptivo más desprotegido y menor conocimiento de la fisiología de la reproducción con relación al grupo B; las jóvenes del grupo C se caracterizaron por frecuentar más la escuela, y la preservación de la virginidad para el matrimonio fue relatada por 1/3 del grupo. En las mujeres con hasta 25 años, el embarazo antes de los 20 fue percibido con más consecuencias positivas que negativas en la vida amorosa, conyugal, social y autoestima. CONCLUSIONES: Hay asociación significativa entre embarazo antes de los 20 años con mayor pobreza y menor escolaridad. En ausencia de mejores condiciones de vida y de oportunidades, el embarazo, aunque no sea previsto, se establece como "proyecto de vida" en comparación con su inexistencia.OBJECTIVE: Analyze the sociodemographic characteristics and the sexual and reproductive behavior of young women. METHODS: A cross-sectional nationally representative study was performed about sexual, contraceptive and reproductive behavior with 2,991 women age 15 to 20 years in the National Survey on Demography and Health of Women and Children, 2006. The women were classified into three groups: sexual initiation and pregnancy before the age of 20 (group A); sexual initiation but no pregnancy before the age of 20 (group B) and no sexual initiation (group C). Women until age 25 years were included in the study about reasons for becoming pregnant and the implications for their lives. Statistical analysis considered survey weights and the complex sample design. The association between two categorical variables was assessed by chi-square test. The behavior variables were assessed using a global linear model. RESULTS: Women in group A were mainly black, poorer and with lower education level. These women had an early sexual initiation, less safe contraceptive behavior and less knowledge of reproduction physiology in comparison with group B; young women in group C were characterized by greater attendance at school and 1/3 of this group claimed to maintain their virginity until marriage. For women up to the age of 25, pregnancy before 20 years was perceived as having more positive than negative impacts upon their love life, spousal relationships, social lives and self-esteem. CONCLUSIONS: There is a significant association between pregnancy before the age of 20 and higher poverty and lower educational level. In the absence of better living conditions and opportunities, pregnancy, although unplanned, becomes "a plan for life", and is not seen as a lack of life planning.OBJETIVO: Analisar características sociodemográficas e do comportamento sexual e reprodutivo de mulheres jovens. MÉTODOS: Estudo populacional transversal com representatividade nacional sobre o comportamento sexual, contraceptivo e reprodutivo de 2.991 mulheres de 15 a 20 anos na Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher 2006. As jovens foram classificadas em três grupos: iniciaram a vida sexual e engravidaram antes dos 20 anos (grupo A); iniciaram a vida sexual e não engravidaram antes dos 20 (grupo B) e não iniciaram a vida sexual (grupo C). Mulheres de até 25 anos foram consideradas para o estudo das razões da gravidez e de suas implicações na vida. As análises estatísticas consideraram os pesos e o planejamento amostral complexo. A associação entre duas variáveis categóricas foi avaliada pelo teste tipo qui-quadrado. Quanto às comportamentais, utilizou-se modelo linear global. RESULTADOS: Mulheres do grupo A eram principalmente negras, mais pobres e com menor escolaridade. Tiveram a primeira relação sexual mais precocemente, comportamento contraceptivo mais desprotegido e menor conhecimento da fisiologia da reprodução em relação ao grupo B; as jovens do grupo C caracterizaram-se por maior frequência à escola e a preservação da virgindade para o casamento foi alegada por um 1/3 desse grupo. Para as mulheres com até 25 anos, a gravidez antes dos 20 foi percebida como tendo implicações mais positivas que negativas na vida amorosa, conjugal, social e autoestima. CONCLUSÕES: Há associação significativa entre gravidez antes dos 20 anos com maior pobreza e menor escolaridade. Na ausência de melhores condições de vida e de oportunidades, a gravidez, embora não prevista, configura-se como "projeto de vida" e não sua mera ausência

Social representations of AIDS and their quotidian interfaces for people living with HIV

This qualitative descriptive study, guided by the Social Representations Theory, aimed to describe the content of the social representations regarding the Acquired Immunodeficiency Syndrome (AIDS) for seropositive individuals in outpatient monitoring of the public health network and to analyze the interface of the social representations of AIDS with the quotidian of the individuals living with human immunodeficiency virus (HIV), especially in the adherence to treatment process Interviews were conducted with 30 seropositive individuals and the manual content analysis technique was used. From the analysis, six categories emerged that re-translated the quotidian of seropositive people permeated by the stigma, prejudice, struggle for life and the need for the continuous use of antiretrovirals. AIDS was assimilated to chronic diseases such as diabetes, showing a trend of transformation of the social representation of AIDS, substituting the idea of death, with life. It is concluded that people living with HIV are more optimistic due to effective treatments for the control of the disease.Se trata de un estudio cualitativo descriptivo orientado por la Teoría de las Representaciones Sociales, que objetivó describir el contenido de las representaciones sociales acerca de la Síndrome de Inmunodeficiencia Adquirida (SIDA) para los usuarios seropositivos en acompañamiento de ambulatorio en la red pública de salud y analizar la interconexión de las representaciones sociales del Sida con lo cotidiano de los individuos que viven con el virus de la inmunodeficiencia humana (HIV), especialmente al proceso de adhesión al tratamiento. Se realizaron entrevistas con 30 individuos seropositivos. Se utilizó la técnica de análisis de contenido manual. Del análisis, emergieron seis categorías que tradujeron lo cotidiano de seropositivos impregnados por el estigma, prejuicio, lucha por la vida y la necesidad del uso continuo de antirretrovirales. El Sida fue comparado a enfermedades crónicas como la diabetes, evidenciando una tendencia de transformación de la representación social del Sida, substituyendo la idea de muerte, por la de vida. Se concluye que las personas que conviven con HIV están más optimistas debido a los tratamientos eficaces en el control de la enfermedad.Trata-se de estudo qualitativo descritivo, norteado pela teoria das representações sociais.

Conclui-se que as pessoas que convivem com HIV estão mais otimistas devido aos tratamentos eficazes no controle da doença

HIV prevalence among female sex workers, drug users and men who have sex with men in Brazil: A Systematic Review and Meta-analysis

<p>Abstract</p> <p>Background</p> <p>The Brazilian response towards AIDS epidemic is well known, but the absence of a systematic review of vulnerable populations ─ men who have sex with men (MSM), female sex workers (FSW), and drug users (DU) remains a main gap in the available literature. Our goal was to conduct a systematic review and meta-analysis of studies assessing HIV prevalence among MSM, FSW and DU, calculating a combined pooled prevalence and summarizing factors associated the pooled prevalence for each group.</p> <p>Methods</p> <p>Nine electronic databases (MEDLINE via PubMed, EMBASE, Cochrane CENTRAL, AIDSLINE, AMED, CINAHL, TOXNET, SciELO, and ISI-Web of Science) were searched for peer-reviewed papers published in English, French, Spanish or Portuguese, from 1999 to 2009. To be included in the review, studies had to measure HIV prevalence and/or incidence as the primary outcome among at least one specific population under analysis.</p> <p>Results</p> <p>The studies targeting the three populations analyzed mostly young participants aged 30 years or less. Among FSW, eight studies were selected (3,625 participants), consistently identifying higher condom use with sexual clients than with occasional and stable partners. The combined HIV prevalence for FSW was 6.2 (95% CI: 4.4-8.3). Ten studies targeting MSM were identified (6,475 participants). Unprotected anal intercourse was commonly reported on those studies, but with great variability according to the nature of the relationship - stable vs. occasional sex partners - and sexual practice - receptive vs. insertive anal sex. Pooled HIV prevalence for MSM was 13.6 (95% CI: 8.2-20.2). Twenty nine studies targeting DU were identified (13,063 participants). Those studies consistently identified injection drug use and syringe/needle sharing as key predictors of HIV-infection, as well as engagement in sex work and male-to-male sex. The combined HIV prevalence across studies targeting DU was 23.1 (95% CI: 16.7-30.2).</p> <p>Conclusions</p> <p>FSW, MSM and DU from Brazil have a much risk of acquiring HIV infection compared to the general population, among which HIV prevalence has been relatively low (~0.6%). Those vulnerable populations should be targeted by focused prevention strategies that provide accurate information, counseling and testing, as well as concrete means to foster behavior change (e.g. access to condoms, drug abuse treatment, and clean syringes in the case of active injecting drug users), tailored to gender and culture-specific needs. Programs that provide these services need to be implemented on public health services throughout the country, in order to decrease the vulnerability of those populations to HIV infection.</p
