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

Uso de medicamentos em crianças de zero a seis anos matriculadas em creches de Tubarão, Santa Catarina Drug utilization among children aged zero to six enrolled in day care centers of Tubarão, Santa Catarina, Brazil

OBJETIVO: Identificar o padrão de utilização de medicamentos, nos últimos seis meses, em crianças entre zero e seis anos, em quatro creches de Tubarão, Santa Catarina, no ano de 2007. MÉTODOS: Estudo transversal realizado por meio de questionário semi-estruturado, aplicado aos pais ou responsáveis pelas 413 crianças incluídas na pesquisa, após consentimento informado. Foram coletados dados sobre utilização de medicamentos e informações de saúde. A análise estatística foi feita com auxílio do programa Statistical Package for the Social Sciences 15.0. RESULTADOS: A média de idade das crianças foi 3,7±1,3 anos, sendo 195 (47%) meninas e 218 (53%) meninos. Dentre os adultos que responderam ao questionário, 75% eram mães e 43% tinham oito anos de estudo. Diante de situação de doença, 47% forneciam os medicamentos que tinham em casa. Das crianças pesquisadas, 82 (20%) apresentavam doença crônica e 75 (18%) portavam doença aguda no momento da pesquisa. Houve histórico de reações adversas aos medicamentos em 82 (20%) crianças, sendo a mais freqüente a alergia. A classe de medicamentos mais utilizada foi a dos analgésicos e antitérmicos (45%) e o motivo de uso principal foi febre (32%). Nos últimos seis meses, haviam sido utilizados 763 medicamentos, com média de 1,8 medicamentos por criança, sendo 41% com prescrição médica e 59% por automedicação. CONCLUSÕES: A prática freqüente de automedicação em crianças é um fenômeno potencialmente nocivo à saúde. Esse estudo mostrou que a maioria dos pais ou responsáveis segue essa prática, podendo mascarar doenças graves, gerar quadros de reações adversas e desenvolver resistência bacteriana, além de outras complicações.<br>OBJECTIVE: Identify the pattern of drug utilization in a six-month period among children aged zero to six years old, in Tubarão, Santa Catarina, Brazil, during 2007. METHODS: This cross-sectional study was carried out using a semi-structured questionnaire administered to parents or caretakers of 413 children included in the survey. After signing consent, parents were asked about the use of prescribed and over-the-counter medicines and other health information. Statistical Package for the Social Sciences 15.0 was used for statistical analysis. RESULTS: Out of 413 children, 195 (47%) were girls and 218 (53%) boys. Their mean age was 3.7±1.3 years. Most parents who answered the questionnaire were mothers (75%) and 43% had eight years of schooling. When asked about medication use in the event of diseases, 47% reported that they use medicines available at home. Among the children, 82 (20%) had chronic diseases and 75 (18%) presented an acute illness at the time of the study. Adverse drug reactions were reported by 82 (20%) of the caretakers, being allergy the most frequent. Antipyretics and analgesics were the medicines most frequently used (45%) in order to treat fever (32%). During the last six months, the use of 763 drugs was reported, corresponding to 1.8 drugs/child. Of these, 41% were prescribed by a physician and 59% as self medication. CONCLUSIONS: Parental frequent practice of self medication in treating children is potentially harmful to health. This study showed that most caretakers follow this practice which can mask serious diseases, provoke adverse reactions and develop bacterial resistance, among other complications
