Behavioral surveillance surveys have been carried among military conscripts, in Brazil, since 1996. This paper presents the results of the 2007 survey and compares actual findings with those obtained in previous studies carried out in the period 1999-2002. The conscripts were selected with a two stage sampling stratified by geographical region. The study included a self-reported questionnaire and blood collection for HIV and syphilis testing. Data from 35,432 conscripts aged 17-20 years old were analyzed. The findings show a reduction in regular condom use, with fixed and casual partners, mainly among those with poor educational level. The proportion of conscripts that have sex with other men was maintained (3.2%), but the index of risky sexual behavioral showed worsening results in this group. Also, the HIV prevalence rate increased from 9 to 11.3 per 10,000 in 2007, though the increase was not statistically significant. In conclusion, the evidences found in this paper indicate the need of reformulate policy among young adults.

HIV prevalence and sexual behavior among young male conscripts in the Brazilian army, 2016
Medicine, 2018
Since 1996, the Brazilian Department of Sexually Transmitted Infections (STI), AIDS and Viral Hepatitis (Departamento de Vigilância, Prevenção e Controle das IST, do HIV, AIDS e Hepatites Virais, Secretaria de Vigilância em Saúde, Ministério da Saúde) in collaboration with the Brazilian Ministry of Defense has conducted periodic and anonymous probability sample surveys to determine the human immunodeficiency virus (HIV) prevalence, the sexual and risk behaviors among conscripts of the Brazilian army. This study aimed to estimate the HIV seroprevalence of conscripts in Brazil by geographic region and to describe behavior in relation to the risk of HIV transmission by analyzing data from the Brazilian Conscripts Survey 8th edition performed in 2016.Conscripts were selected with a 2-stage sampling method stratified by geographical region. The study included a self-reported questionnaire and blood collection for HIV, hepatitis, and syphilis testing. Data from 37,282 conscripts between 1...

Objectives: To describe and identify sociodemographic and behavioural characteristics and other factors related to high-risk behaviour for HIV infection of men who have sex with men (MSM) living in Fortaleza, Brazil. Methods: A survey was carried out among 400 MSM aged 14-65 years and recruited through the snowball technique or in gay-identified venues. A semistructured questionnaire was conducted among them. Logistic regression analysis was used to model the dichotomous outcome (high risk or low risk). Results: Forty-four per cent of the participants reported engaging in high-risk sexual behaviour in the previous year. MSM less informed about AIDS, reporting more sexual partners, reporting at least one female partner in the previous year, having anal sex as the favourite way to have sex, and having great enjoyment of unprotected anal sex were more likely to be engaged in risky behaviour. Twentythree per cent of participants reported at least one sexual contact with women during the previous year. Two-thirds of men who had unprotected sex with their female partners also had unprotected anal sex with their male partners. Conclusions: A large proportion of MSM in Fortaleza still remain at elevated risk for contracting HIV infection. The factors predictive of high-risk sexual behaviour are significant in spreading HIV infection among the MSM population and also among their female partners. The lifestyles of these men are different to those of men from other parts of Brazil or outside the country. Preventive interventions need to be culturally and socially specific in order to be effective.
Condom use in Brazil: An overview of the academic production on HIV/AIDS prevention (2007-2011)
Temas em Psicologia, 2013
Since the beginning of the AIDS epidemic, condoms have been the main preventive strategy of the Brazilian policies. This study presents a refl ective essay on the academic production on condom use as a method for HIV/AIDS prevention in Brazil, based on papers published in scientifi c journals between 2007 and 2011 and indexed in the Virtual Health Librar y. It outlines an overview of these studies and their results and conclusions. Despite the diversity of the production analyzed, it was found that the studies concentrated on young people, with great attention given to gender issues. From combined analysis on the goals and the theoretical and methodological frameworks of the articles, six areas of production of knowledge on the subject were identifi ed: epidemiological studies; studies on knowledge and behavior; studies on specifi c contexts; studies on senses and meanings; studies on activities; and review studies. The literature analyzed is presented in a diffuse manner so as it interlocks approaches and directions, which requires an epistemological and methodological maturity of the frameworks used.

This cross-sectional study examined prevalence and correlates of HIV risk behaviors among a random sample of 431 adolescents (aged 12-21 years) attending schools in the Brasilia Federal District. The results showed that 43% of the students were sexually experienced. Condoms were consistently used by 43% of the sexually active students during vaginal intercourse and by 27% during anal intercourse. About 32% and 16% of the participants reported current consumption of alcohol and illegal substances, respectively, with 17% and 4% reporting having sex under their influence. Having "stable" partners was the main reason for not using condoms. Other high-risk correlates included male gender, older age, having repeated a school year, alcohol consumption, sex under the influence of alcohol, heavier alcohol consumption, and illegal substance use. Access to condoms was not reported to be a problem. These data are useful for designing health education interventions in schools and for behavioral surveillance of adolescents.

Background: Many countries are facing concentrated HIV epidemics among vulnerable populations, including men who have sex with men (MSM). Unprotected anal intercourse (UAI) is the main HIV transmission route among them and its understanding in the different cultures and how it relates to HIV transmission, re-infection and development of HIV antiretroviral resistance has important public health implications. Data on UAI among Brazilian MSM are scarce. This study aims to evaluate the prevalence and associated factors of UAI among HIV-infected MSM who had sex with seronegative or male partners with an unknown serostatus. Method: A cross-sectional study nested in a cohort was conducted in Rio de Janeiro, Brazil. The one hundred and fifty five MSM included in the study answered an ACASI interview and provided biological samples. Generalized linear models were used to identify variables associated with UAI.

Aim: To assess the knowledge of HIV/AIDS prevention and factors associated with condom use among adolescent. Methods: A cross-sectional study was conducted among 410 outpatient adolescents. Association between knowledge on the transmission of HIV/AIDS and variables were analyzed using the chi-square test. Logistic regression model was used to estimate the factors associated to condom use. Results: The knowledge about HIV/AIDS transmission was high and lower percentages of knowledge were observed regarding the non-transmission of HIV/AIDS. Younger adolescents revealed less knowledge than older adolescents. After multiple logistic regression the following factors were associated with condom use: male gender (p ¼ 0.029), same age between partners (p ¼ 0.002) and having until 1 year elapsed since sexual initiation (p ¼ 0.001). Conclusion: The knowledge regarding HIV/AIDS prevention was satisfactory. However, this does not imply that adolescents put such knowledge to use.
