Abstract
This study aimed to analyze the association between sociodemographic, programmatic and contextual factors and the receipt of money in exchange for sex among men who have sex with men (MSM). This is a multicenter, cross-sectional study conducted in ten Brazilian cities between 2008 and 2009. Adult MSM recruited through the Respondent Driven Sampling (RDS) were interviewed. Weighted Odds Ratio (ORw) was obtained through logistic regression, retaining the variables associated with the event (p < 0.05) in the final model. Of the total sample, 33.3% reported receiving money in exchange for sex in the last 12 months before the interview. The variables that were independently associated with the event were age less than or equal to 25 years, lower education, lower social classes, previous history of syphilis, using sites or services to find sexual partners in the previous month, very high risk behavior, using illicit drugs in the previous six months, self-identifying as heterosexual or bisexual, having suffered physical violence due to sexual orientation and having suicidal thoughts always or most of the time. It was observed that MSM who received money in exchange for sex had greater socioeconomic, programmatic and contextual vulnerability, potentially increasing the risk of HIV infection than the other MSM in the sample.

Abstract
INTRODUCTION Respondent-Driven Sampling (RDS) has been used in surveys with key populations at risk of HIV infection, such as female sex workers (FSW). This article describes the application of the RDS method among FSW in 12 Brazilian cities, during a survey carried out in 2016. METHODOLOGY A biological and behavioral surveillance study carried out in 12 Brazilian cities, with a minimum sample of 350 FSW in each city. Tests were performed for HIV, syphilis, and hepatitis B and C infections. A social-behavioral questionnaire was also applied. RESULTS The sample was comprised of 4,328 FSW. For data analysis, the sample was weighted according to each participant's network size (due consideration to the implications of RDS complex design and to the effects of homophilia are recommended). DISCUSSION Although RDS methods for obtaining a statistical sample are based on strong statistical assumptions, allowing for an estimation of statistical parameters, with each new application the method has been rethought. In the analysis of whole-sample data, estimators were robust and compatible with those found in 2009. However, there were significant variations according to each city. CONCLUSION The achieved sample size was of great relevance for assessing progress and identifying problems regarding the prevention and treatment of Sexually Transmitted Infections. New RDS studies with more time and operational resources should be envisaged. This could further network development.

Abstract
The aim of this study was to describe metabolic changes in HIV/AIDS patients according to the treatment regimen. It was a retrospective cohort conducted from 2002 to 2014. Researchers surveyed clinical variables and treatment regimen of 538 individuals. They used measures of central tendency and marginal logistic regression to determine the influence of the treatment regimen on clinical variables over time; survival was estimated using Kaplan-Meier curves. 56.2% of patients were male, 82.2% white, 33.8% had 4 to 7 years of study, 49.2% were married, 98.5% had sexual transmission, and 89.0% were heterosexuals. During the study period, 24.4% had hypertension, 18.2% changed cholesterol, 39.7% low HDL, 51.3% high triglycerides and 33.3% hyperglycemia. Treatment regimens with nucleotide reverse transcriptase inhibitors associated with protease inhibitors, and the association of different classes of antiretrovirals have been associated with greater lipid changes. Higher metabolic changes were observed in patients with longer treatment time. It is concluded that preventive measures, as well as early treatment, can contribute to minimize the risks of developing cardiovascular diseases.

Abstract
Brazil has the largest population of individuals living with HIV/AIDS in Latin America with a disproportional prevalence of infection among men who have sex with men (MSM). This study evaluated PrEP awareness by age (18-24, 25-35, ≥36 years), its associated factors and the willingness to use HIV prevention technologies among MSM using a GSN app in Brazil. Inclusion criteria were ≥18 years-old, cisgender men and HIV-negative serostatus. Of 7242 individuals, 4136 (57%) completed the questionnaire. PrEP awareness was reported by 51% (though lower among MSM aged 18-24 and ≥36 years) and its associated factors were higher family income, most friends with the same sexual orientation, high number of male sexual partners and marijuana use. HIV testing (never vs. at least once) lead to an almost 3-fold increase in the odds of PrEP awareness. High HIV risk perception led to increased PrEP awareness only among MSM aged 18-24 years. A total of 2335 (56%) was willing to use daily oral PrEP. PrEP awareness remains low in Brazil and mobile tools are key strategies to reach MSM and increase awareness of prevention technologies. Community-based interventions could add to online campaigns to reach the most vulnerable, which include young, non-white and lower-income MSM.

Abstract
INTRODUCTION Over 30 years after the acquired immunodeficiency syndrome epidemic, several strategies have been implemented to verify the trend of the infection, the profile of the affected individuals, and the impact of prevention and control measures, with notification of asymptomatic carriers being the most recent measure. This study aimed to verify the geographic distribution of human immunodeficiency virus/acquired immunodeficiency syndrome and analyze the association between case definition criteria, sociodemographic data, and clinical aspects of the disease in the State of Minas Gerais between 2007 and 2016. METHODS In this ecological and analytical study, 35,349 cases of human immunodeficiency virus/acquired immunodeficiency syndrome reported in the State of Minas Gerais between 2007 and 2016 were analyzed. The data were analyzed using multiple correspondence factor analysis, time series analysis, descriptive statistics, and spatial distribution of the cases by macro-region. RESULTS The majority of the patients were brown-skinned individuals, alive, diagnosed with human immunodeficiency virus/acquired immunodeficiency syndrome on the basis of the criteria adapted from the Centers for Disease Control and Prevention, and living in municipalities with more than 50,000 (80.5%) inhabitants. Between 2007 and 2016, there was an increase in the number of criteria used for diagnosing human immunodeficiency virus. By contrast, a consequent decrease was observed in the number of criteria used for defining cases, which were adapted from the Centers for Disease Control and Prevention, Rio de Janeiro/Caracas, and for identifying AIDS-related deaths. Young people aged between 13 and 29 years, individuals whose education level is compatible with the observed age, and homosexual men were associated with the HIV+ criterion. CONCLUSIONS Out study showed that after the mandatory notification of human immunodeficiency virus-positive cases in 2014, there was a decrease in other criteria for defining human immunodeficiency virus/acquired immunodeficiency syndrome cases and changes in the profile of people living with human immunodeficiency virus/acquired immunodeficiency syndrome.

Abstract
BACKGROUND Female sex workers (FSW) bear a high burden of sexually transmitted infections (STI). In this paper, we estimate the prevalence of human immunodeficiency virus (HIV), HBV = hepatitis B virus (HBV), HCV = hepatitis C virus (HCV), syphilis and co-infections in the second Biological and Behavioral Surveillance Survey among FSW in Brazil. METHOD The survey was conducted in 12 Brazilian cities from July to November 2016. We used respondent-driven sampling (RDS) to recruit 350 FSW in each city. Rapid tests were used for screening HIV, syphilis, HCV, and HBV. Confirmatory tests were performed on all samples with reactive rapid test result. All testing algorithms and interpretations were done according to the recommendations of the Department of STI/AIDS and viral hepatitis, Ministry of Health. The STI diagnoses were given by: confirmed HIV infection by a positive result on Western blot; active syphilis infection, defined by a RPR titer equal or greater than 1/8; viremia period of HBV and HCV infections, characterized by a detectable (or quantifiable) viral load. Prevalence estimates and standard errors were calculated using statistical procedures suitable for data collected by RDS. RESULTS Excluding the seeds, 4245 FSW were enrolled. Prevalence estimates were: HIV 5.3% (95% CI: 4.4%-6.2%); active syphilis 8.5% (95% CI: 7.3%-9.7%); HBV 0.4% (95% CI: 0.2%-0.7%); and, HCV 0.9% (95% CI: 0.6%-1.3%). Among the 4154 FSW tested for the 4 infections, 13.3%; (95% CI 12.0%-14.8%) were diagnosed with at least one of the infections, of which 87.6% (95% CI: 83.3%-90.9%) had single infections. The prevalence of HIV/syphilis co-infection was 1.09% (95% CI: 0.7%- 1.6%) and of HIV/HCV or HBV infections was 0.4% (95% CI: 0.2%-0.7%). CONCLUSIONS Our results reveal the need to conduct more studies to estimate the prevalence of STI and co-infections among FSW in Brazil. Longitudinal trends in the prevalence estimates of HIV and other STI provide information to monitor changes in this high-risk population. Additionally, the study highlights the importance of measuring the hepatitis burden among FSW living with HIV, and the need of including FSW in all aspects of STI prevention, care, and treatment programs.

Awareness of Prevention Strategies and Willingness to Use Preexposure Prophylaxis in Brazilian Men Who Have Sex With Men Using Apps for Sexual Encounters: Online Cross-Sectional Study. JMIR Public Health Surveill 2018; 4:e11. [PMID: 29358160 PMCID: PMC5799718 DOI: 10.2196/publichealth.8997] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2017] [Revised: 11/06/2017] [Accepted: 11/26/2017] [Indexed: 12/12/2022] Open
Abstract
Background Geosocial networking (GSN) smartphone apps are becoming the main venue for sexual encounters among Brazilian men who have sex with men (MSM). To address the increased HIV incidence in this population, preexposure prophylaxis (PrEP) was recently implemented in the Brazilian public health system in the context of combined HIV prevention. Objective This study aimed to describe the characteristics of MSM using GSN apps for sexual encounters, their awareness of prevention strategies, and willingness to use PrEP. Methods This study was an online cross-sectional study conducted in 10 Brazilian state capitals from July 1 to July 31, 2016. The questionnaire was programmed on SurveyGizmo and advertised in two GSN apps used by MSM to find sexual partners (Hornet and Grindr). Inclusion criteria were >18 years of age, cisgender men, with an HIV-negative status. Eligible individuals answered questions on: demographics; behavior; and knowledge, preferences, and willingness to use PrEP, nonoccupational postexposure prophylaxis (nPEP), HIV self-testing (HIVST), and condoms. Logistic regression modeling was performed to assess the factors associated with daily oral PrEP willingness. Results During the study period, 8885 individuals provided consent and started the questionnaire. Of these, 23.05% (2048/8885) were ineligible, 6837 (6837/8885, 76.94%) initiated, and 5065 (5065/8885, 57.00%) completed the entire questionnaire and were included in the present analysis. Median age was 30 years (interquartile range: 25-36), most self-declared as MSM (4991/5065, 98.54%), white (3194/5065, 63.06%), middle income (2148/5065, 42.41%), and had 12 or more years of schooling (3106/5062, 61.36%). The majority of MSM (3363/5064, 66.41%) scored >10 points (high risk) on The HIV Incidence Risk for MSM Scale, but only 21.39% (1083/5064) had a low perceived likelihood of getting HIV in the next year. Daily use of apps for sex was reported by 35.58% (1798/5054). Most MSM (4327/5065, 85.43%) reported testing for HIV at least once in their lifetime and 9.16% (464/5065) used nPEP in the previous year. PrEP, nPEP, and HIVST awareness was reported by 57.89% (2932/5065), 57.39% (2907/5065), and 26.57% (1346/5065) of participants, respectively. Half of all respondents (2653/5065, 52.38%) were willing to use daily oral PrEP, and this finding was associated with higher numbers of male sexual partners (adjusted odds ratio [AOR] 1.26, 95% CI 1.09-1.47), condomless receptive anal intercourse (AOR 1.27, 95% CI 1.12-1.44), sex with HIV-positive partner versus no HIV-positive partner (one HIV-positive partner: AOR 1.36, 95% CI 1.11-1.67), daily use of apps for sexual encounters (AOR 1.48, 95% CI 1.17-1.87), high and unknown perceived likelihood of getting HIV in the next year (AOR 1.72, 95% CI 1.47-2.02 and AOR 1.39, 95% CI 1.13-1.70), sexually transmitted infection diagnosis (AOR 1.25, 95% CI 1.03-1.51), stimulant use (AOR 1.24, 95% CI 1.07-1.43), PrEP awareness (AOR 1.48, 95% CI 1.30-1.70), and unwillingness to use condoms (AOR 1.16, 95% CI 1.00-1.33). Conclusions Our results evidenced high-risk scores in the studied population, suggesting the importance of PrEP use. Those individuals presenting risky sexual behaviors were more willing to use PrEP. Nonetheless, only 58% (2932/5065) of individuals had heard about this prevention strategy. Efforts to increase awareness of new prevention strategies are needed, and mobile health tools are a promising strategy to reach MSM.

Abstract
Objectives: To estimate the human immunodeficiency virus (HIV) viral load in the Brazilian population and to assess the potential impact of highly active antiretroviral therapy (HAART) in reducing new infections to build evidences and to gather information to support health policies. Methods: Spatial analysis and modeling tools were used to describe the existing patterns of the viral load density, using the Kernel method. Data on viral load and treatment were retrieved from the databases Laboratory Tests Control System (SISCEL), which contains information on the individual's history of viral load, and Medication Logistics Control System (SICLOM), which controls the dispensing of drugs used for antiretroviral therapy. Results: It was observed that the community viral load (CVL) decreased progressively from 2007 to 2011, accompanied by a decrease of more than 32% in the mean CVL (CVLM) - 22,900 copies/mL in 2007 versus 15,418 copies/mL in 2011. During this period, there was a reduction of CVLM in all regions of Brazil, although North and Northeast showed, respectively, CVLM 1.7 and 1.5 times higher than that in the Southeast region. A comparison between the individuals who underwent and who did not undergo HAART showed an increase of up to 3.9 times in 2011 in the viral load among those who did not undergo the therapy. Conclusion: The approach presented in this study indicates the existence of clusters with high concentrations. The use of Kernel in the identification of clusters proved to be a good tool for exploratory analysis, enabling the risk identification in certain geographic areas without the usual political and administrative divisions.

Abstract
This study aimed to identify incentives and barriers to HIV testing in men who have sex with men (MSM). This was a cross-sectional study of MSM who had lived at least three months in greater metropolitan Fortaleza, Ceará State, Brazil, 2010. The study recruited 391 men ≥ 18 years of age who reported sexual relations with men in the previous six months, using Respondent Driven Sampling. Personal network and socio-demographic data were collected and HIV testing was offered, analyzed with RDSAT 6.0 and Stata 11.0. The majority were young (40.3%), had 5 to 11 years of schooling (57.3%), were single (85.1%), had low income (37.6%), and 58.1% had tested for HIV some time in life. Incentive to test: certainty of not being infected (34.1%) and the exposure to national campaign Fique Sabendo [Know your Status] (34%). Barriers: trust in partner(s) (21%) and fear of discrimination if tested positive (20.3%). Policies should be developed to ensure test confidentiality and communication campaigns focusing on information gaps and encouragement for testing.

Factors Associated with Low Levels of HIV Testing among Men Who Have Sex with Men (MSM) in Brazil. PLoS One 2015; 10:e0130445. [PMID: 26098559 PMCID: PMC4476690 DOI: 10.1371/journal.pone.0130445] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Accepted: 05/20/2015] [Indexed: 11/29/2022] Open
Abstract
The aim of this study was to assess risk factors associated with low levels of HIV testing among MSM recruited through respondent driven sampling (RDS) in Brazil. Of 3,617 participants, 48.4% had never tested previously for HIV. A logistic model indicated that younger age, lower socioeconomic class, education, poor HIV/AIDS knowledge, no history of cruising, and having been tested during the study were characteristics independently associated with low levels of previous HIV testing. The HIV testing rate among MSM in Brazil is still low in spite of the availability of a large number services providing universal and free access to HIV/AIDS diagnosis and treatment. To respond to low utilization, the authors propose a higher priority for testing for key populations such as MSM, expanded education, expanding testing sites and a welcoming and nonjudgmental environment in health services.

Abstract
Combined antiretroviral therapy is now acknowledged for preventing new HIV infections, besides decreasing mortality and morbidity. However, in many Latin America countries the epidemic is still driven by unprotected sexual intercourse. This study aims to describe sexual practices related to HIV/STD and to evaluate factors associated to unprotected sex among men who have sex with women (MSW) and men who have sex with men (MSM) under care at a reference center for HIV in Rio de Janeiro, Brazil. A cross-sectional study, nested in a Brazilian clinical cohort, evaluated the sexual practices of 404 sexually active HIV-positive MSW and men who have MSM. Approximately 30 % of them reported unprotected sexual practices during the 6 months prior to the interview. Most frequent risky practices reported were unprotected vaginal sex among MSW and unprotected receptive anal sex among MSM. Factors increasing the chance of unprotected sexual practices among MSW were the partner's desire of becoming pregnant (OR 2.81; CI 95 %: 1.36-5.95). To have received comments about excessive consumption of alcohol (OR 2.43; CI 95 %: 1.01-5.83), illicit drug use (OR 4.41; CI 95 %: 1.75-11.60) and lived in marital situation (OR 2.10; CI 95 %: 1.09-4.08) were significantly associated with unsafe sexual practices among MSM. The results highlight that health care of men living with HIV, as well as the prevention strategies, must consider the particularities of sexual behavior practiced by people who differ in sexual orientation.

Abstract
Reconhecendo a relevância do incremento na oferta de testagem anti-HIV, problematiza-se a concepção de oferta à luz dos conceitos de acesso e demanda. O mero foco na oferta da testagem mostra-se insuficiente frente à complexidade e dinamicidade do processo, desde a identificação da sua necessidade até a realização do teste e seus possíveis desdobramentos, incluindo o tratamento. Ademais, o modelo de campanha para incentivo à testagem não se coaduna com proposições que valorizem o protagonismo social dos cidadãos nem atendam às especificidades da disseminação da epidemia de AIDS. Postula-se a importância de desenvolver estudos que focalizem mais detidamente a demanda por testagem anti-HIV.

Abstract
OBJECTIVE To describe trends in the incidence of Aids cases according to age and gender from 1986 to 2008. METHODS Analyses of Aids trends according to age group and to gender was carried out Londrina, Southern Brazil. The timeframe was divided into two periods (1986-1995 and 1996-2008). Of the polynomial models, it was the first-degree polynomial model which best explained the Aids epidemic within the two periods. The incidence rate of Aids among men who have sex with other men (MSM), injecting drug users (IDU), heterosexual men and women was calculated. RESULTS During the first period, from 1986 to 1995, there was an increase in the incidence of Aids in almost all age groups and the epidemic spread across both sexes (p < 0.001), although this was more marked in men aged 14-39. The second period (1996-2008) did not show a positive or negative statistical increase, indicating that the epidemic had stabilized. A significant fall in the rate for the male 14 to 29 age group was found, with increases of 0.88 and 0.87 for the first and second period respectively. Cases in women aged 50 and over showed a marked increase (p = 0.019). The IDU and MSM groups predominated as the categories with the most exposure, with MSM taking over from IDU in the last three years of the study. From 2000 onwards, incidences in females aged 15 to 49 overtook that of heterosexual men. CONCLUSIONS The study showed a decrease in incidence in the younger age groups and stabilization in the other age groups. There is a need for different approaches in order to reach groups with several characteristics due to the increase in the proportion of women and MSM within the exposure categories.

Abstract
OBJETIVOS: Analisar a cobertura da Política de Incentivo do Ministério da Saúde para Programas de Aids e as características das ações de prevenção, assistência, gestão e apoio às organizações da sociedade civil induzidas nos Estados e municípios. METODOLOGIA: Os Planos de Ações e Metas de 2006, das 27 Unidades Federadas e de 427 municípios incluídos na Política de Incentivo, foram analisados segundo indicadores estabelecidos para aferir a complexidade e a sustentabilidade das ações induzidas, a inclusão de populações prioritárias e a capacidade de intervenção na epidemia. Informações sobre população e casos de aids registrados foram utilizadas para mensurar a cobertura. RESULTADOS: Os municípios incluídos representaram uma cobertura de 85,2% dos casos de aids do País. Houve uma baixa proporção de secretarias estaduais (48,2%) e municipais (32,6%) de saúde que contemplaram, concomitantemente, ações de prevenção para a população geral e as de maior prevalência da doença, assim como ações para o diagnóstico do HIV, o tratamento de pessoas infectadas e a prevenção da transmissão vertical. Em relação às populações prioritárias, 51,9% dos Estados e 31,1% dos municípios propuseram ações específicas na prevenção e na assistência. Estados (44,4%) e municípios (27,9%) com Planos abrangentes estão mais concentrados no Sudeste e em cidades de grande porte, representando a maioria dos casos de aids do País. CONCLUSÃO: A Política de Incentivo do Ministério da Saúde compreende as regiões de maior ocorrência da aids no Brasil, porém, o perfil da resposta induzida encontra-se parcialmente dissociado das características epidemiológicas da doença no País.

Abstract
This descriptive study focused on the mortality profile associated with hepatitis B virus (HBV) in Brazil as a whole and by region, based on data from the Mortality Information System (MIS). The study sample consisted of deaths from HBV recorded in the MIS from January 1, 2000, to December 31, 2009. The crude mortality rate remained constant in the country; the proportion of hepatocellular carcinoma with HBV as the associated cause was no greater than 7%. The standardized mortality rate was highest in the North of Brazil, and the proportional mortality rate was higher in males. In 2009, the potential years of life lost (PYLL) were highest in males in the 50-59-year age bracket and in females in the 40-49-year bracket. The largest increase in PYLL occurred in males 60 to 69 years of age. The study emphasizes the importance of scaling up preventive measures against HBV, in addition to expanding access to early diagnosis in order to reduce HBV mortality in the coming decades.

Abstract
INTRODUCTION The purpose of this study was to analyze the dynamics of the AIDS epidemic affecting adolescents in Rio de Janeiro to establish healthy prevention strategies. The incidence of AIDS in Brazil is declining among men who have sex with men (MSM) except in individuals between 13 and 19 years of age, and the feminization phenomenon is more pronounced among adolescents. METHODS We evaluated data from Sistema de Informações de Agravos de Notificação (SINAN) regarding cases of AIDS in patients aged between 13 and 19 years through November 2009. RESULTS This study includes 656 cases. The incidence of AIDS increased until 1998, and, since 1996, more cases have been diagnosed in girls than in boys. The homo/bisexual exposure category predominantly consisted of boys (50.8%), and the heterosexual category predominantly consisted of girls (88.9%). The geographic distribution of the cases by year of diagnosis revealed that the increase was proportionally larger in the poorest area and that there was a large decrease in the wealthiest area. A decreasing linear tendency was observed in the relationship between the year of diagnosis and the human development index (HDI). CONCLUSIONS This study demonstrates the need for greater investment in sexual health and reproductive services in the poorest areas of the city and in the promotion of healthy sexual practices directed to MSM and female adolescents.

Abstract
BACKGROUND Understanding how food insecurity among women gives rise to differential patterning in HIV risks is critical for policy and programming in resource-limited settings. This is particularly the case in Brazil, which has undergone successive changes in the gender and socio-geographic composition of its complex epidemic over the past three decades. We used data from a national survey of Brazilian women to estimate the relationship between food insecurity and HIV risk. METHODS AND FINDINGS We used data on 12,684 sexually active women from a national survey conducted in Brazil in 2006-2007. Self-reported outcomes were (a) consistent condom use, defined as using a condom at each occasion of sexual intercourse in the previous 12 mo; (b) recent condom use, less stringently defined as using a condom with the most recent sexual partner; and (c) itchy vaginal discharge in the previous 30 d, possibly indicating presence of a sexually transmitted infection. The primary explanatory variable of interest was food insecurity, measured using the culturally adapted and validated Escala Brasiliera de Segurança Alimentar. In multivariable logistic regression models, severe food insecurity with hunger was associated with a reduced odds of consistent condom use in the past 12 mo (adjusted odds ratio [AOR] = 0.67; 95% CI, 0.48-0.92) and condom use at last sexual intercourse (AOR = 0.75; 95% CI, 0.57-0.98). Self-reported itchy vaginal discharge was associated with all categories of food insecurity (with AORs ranging from 1.46 to 1.94). In absolute terms, the effect sizes were large in magnitude across all outcomes. Underweight and/or lack of control in sexual relations did not appear to mediate the observed associations. CONCLUSIONS Severe food insecurity with hunger was associated with reduced odds of condom use and increased odds of itchy vaginal discharge, which is potentially indicative of sexually transmitted infection, among sexually active women in Brazil. Interventions targeting food insecurity may have beneficial implications for HIV prevention in resource-limited settings.

Abstract
Given the implications of stigma for HIV/AIDS prevention and control of the epidemic, as emphasized by UNAIDS, this study analyzes the Brazilian academic production on health, AIDS, stigma, and discrimination, available in the SciELO database from 2005 to 2010. Brazilian research on the theme is modest as compared to the international literature, but the studies follow the same trend of focusing on individual experiences of discrimination as opposed to analysis of stigma and discrimination as social processes associated with power relations and domination (macro-social structures) and the characteristics of individuals and social groups that shape social interactions. The current study seeks to analyze the reasons for the scarcity of studies on the social perspective towards stigma and discrimination in the field of public health and the implications for the development of proposals to deal with HIV/AIDS-related discrimination.

Abstract
The objective of this study is to characterize survival in children with AIDS diagnosed in Brazil between 1999-2002, compared with the first national study (1983-1998). This national retrospective cohort study examined a representative sample of Brazilian children exposed to HIV from mother-to-child transmission and followed through 2007. The survival probability after 60 months was analyzed by sex, year of birth and death, clinical classification, use of antiretroviral therapy (ART) and prophylaxis for opportunistic diseases. 920 children were included. The survival probability increased: comparing cases diagnosed before 1988 with those diagnosed from 2001-2002 it increased by 3.5-fold (from 25% to 86.3%). Use of ART, initial clinical classification, and final classification were significant (p < 0.001) predictors of survival. Issues regarding quality of records and care were identified. The results point to the success of the Brazilian policy of providing ART. The improvement of clinical status contributes to quality of life, while indicating challenges, particularly practices to improve long-term care.

Abstract
BACKGROUND HIV prevalence is 15 times higher among female sex workers (FSWs) than in the overall Brazilian female population. In this article, we investigated factors associated to HIV infection among FSW, recruited by Respondent-driven sampling (RDS), in 10 Brazilian cities in 2008-2009. METHOD The total sampling was 2523 FSWs. The variables considered in the study included sociodemographic characteristics and those related to profession, knowledge, and source of information on sexually transmitted infection/AIDS, access to condoms, sexual behavior, health care and sexually transmitted infection signs, discrimination and violence, and the use of alcohol and drugs. Sampling weights were proportional to the inverse of network size and for the generation of global results for the 10 cities, data were calibrated by the population size. Multivariate logistic regression models were used, taking into account the dependency structure of observations. RESULTS The longest period of prostitution (odds ratio [OR], 1.040; 95% confidence interval [CI], 1.013-1.067), the lowest price charged for sex (OR, 0.713; 95% CI, 0.522-0.970), the association with other sexually transmitted infections such as syphilis (OR, 2.186; 95% CI, 1.064-4.488), and the fact of would waive the use of condom on client's request (OR, 3.735; 95% CI, 1.449-9.661) were the most important associated risk factors to HIV infection among FSWs. Purchase of condoms (OR, 0.503; 95% CI, 0.304-0.833) was a relevant preventive factor. CONCLUSIONS The use of RDS proved to be appropriate for the recruitment of FSWs as long as the statistical analysis takes into account the dependency structure of observations. The HIV infection predictors here depicted can support public health policies focused on this population group in Brazil.

Abstract
The aim of this study was to identify different profiles in the AIDS epidemic in Brazil by relating them to the health sector's organization, situations involving increased risk of infection, and the degree of implementation of the response by health services. The Brazilian municipalities (counties) were grouped according to the magnitude of the epidemic and its trends from 2002 and 2006, and were then studied using indicators obtained from secondary databases. Municipalities with large epidemics (39%) displayed more situations associated with risk of infection, and those with an upward trend in incidence (11.5%) showed a lower degree of response. Cities with large epidemics but with downward or stable trends had 68.6% of all the anonymous testing centers and 75.8% of the outpatient clinics, and performed 81.4% of all the HIV antibody tests in the health system. Preventive measures in schools and primary health services showed low coverage rates. Differences were observed between geographic regions. Inequalities in the degree of implementation of the response to HIV may contribute to different profiles in the epidemic around the country.

Abstract
The objective of this paper was to describe the process of transferring two methods for sampling most-at-risk populations: respondent-driven sampling (RDS) and time-space sampling (TSS). The article describes steps in the process, the methods used in the 10 pilot studies, and lessons learned. The process was conducted in six steps, from a state-of-the-art seminar to a workshop on writing articles with the results of the pilot studies. The principal investigators reported difficulties in the fieldwork and data analysis, independently of the pilot sampling method. One of the most important results of the transfer process is that Brazil now has more than 100 researchers able to sample MARPs using RDS or TSS. The process also enabled the construction of baselines for MARPS, thus providing a broader understanding of the dynamics of HIV infection in the country and the use of evidence to plan the national response to the epidemic in these groups.

Abstract
The aim of this study was to evaluate strategies by the Brazilian Ministry of Health to expand the municipal response to AIDS. Cities "included" and "not included" in Federal strategies for "municipalization" of the response were compared according to the response profile and trends in the epidemic. Multinomial logistic regression was used, among other statistical procedures. Municipalities included from 1994 to 1998 showed higher chances of providing HIV diagnostic testing [OR = 15.0; 95%CI: 5.6-40.1], of having AIDS services [OR = 18.4; 95%CI: 8.4-40.5], and reducing cases involving heterosexual [OR = 3.1; 95%CI: 1.4-7.3], homosexual/bisexual [OR = 3.0; 95%CI: 1.4-6.2], and IDU transmission [OR = 6.6; 95%CI: 2.9-14.9] as compared to those "included in 2003" and "not included". There were no associations between the included Municipalities, greater coverage in prevention, the reduction in cases due to vertical transmission or blood transfusion, or mortality rates. Municipalities with a more structured response were associated with better results. The findings suggest that the municipalization policy contributed to improvement in the local response to AIDS.

HIV prevalence among female sex workers, drug users and men who have sex with men in Brazil: a systematic review and meta-analysis. BMC Public Health 2010; 10:317. [PMID: 20529289 PMCID: PMC2898825 DOI: 10.1186/1471-2458-10-317] [Citation(s) in RCA: 75] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2010] [Accepted: 06/07/2010] [Indexed: 11/06/2022] Open
Abstract
Background 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. Methods 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. Results 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). Conclusions 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.

Grangeiro A, Escuder MML, Castilho EA. Magnitude and trend of the AIDS epidemic in Brazilian cities, from 2002 to 2006. Rev Saude Publica 2010; 44:430-40. [PMID: 20464259 DOI: 10.1590/s0034-89102010005000013] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2009] [Accepted: 02/09/2010] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE To analyze different patterns of occurrence of AIDS in Brazilian cities between 2002 and 2006, associating trend and magnitude with socio-demographic indicators and local characteristics of the epidemic. METHODS This was an ecological study that categorized cities according to magnitude and trend of the epidemic and subsequently analyzed, considering social indicators, types of HIV transmission and year of first case reported. Data came from the Brazilian Epidemiological Surveillance System, the Brazilian Institute of Geography and Statistics and the United Nations Development Program for Brazil. Linear regression was used to estimate trend and chi-square statistics and ANOVA to analyze indicators. RESULTS A total of 4,190 cities (75.3%) reported AIDS cases between 2002 and 2006. Of these, 3,403 (81.2%) had an occurrence of "small magnitude" (mean=4.7 cases), 367 (8.8%) of "average magnitude" (mean=30.3 cases) and 420 (10.0%) of "great magnitude" (mean=378.7 cases). Cases of "small magnitude" were associated with lower incidence; beginning of the epidemic after 1991; presence of one or two types of transmission; especially heterosexual contact; with occurrences of cases in one or two years of the period; and lower human development index (HDI). Those of a "great magnitude" were associated with larger cities and higher HDI; presence of all types of transmission; beginning of the epidemic between 1980/1991; and trend towards reduction/stabilization, especially due to a decrease in transmission among injecting drug users. Growth of the epidemic was concentrated in "small magnitude" cities, although without significance to the point of changing proportional participation (8.7%) of these cities in the group of cases in Brazil. CONCLUSIONS The AIDS epidemic remains concentrated in urban centers and the spread of cases to the countryside is characterized by irregular occurrence and small magnitude. Cities with low HDI and exclusive transmission through heterosexual contact showed low capacity of increase and the reduction of the epidemic is especially associated with the decrease in transmission among injecting drug users.
