HIV-related risky practices among Brazilian young men, 2007
Cadernos de saúde pública, 2011
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...
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...

PURPOSE: To present selected results of military conscript surveys related to HIV/AIDS, conducted in Brazil, 1997-2002. METHODS: Questionnaires including information on socio-demographic data, sexual behavior practices, sexually transmitted infections-related problems, and use of injecting drugs were completed by 30970 individuals, obtained through a 2-stage sampling. An index of sexual risk behavior was developed to take into account multiplicity of partners and irregularity of condom use. The HIV infection prevalence rate was estimated for 2002. Logistic regression was used to identify the most important determinants of HIV infection. RESULTS: The percentage of regular condom use increased from 38% (1997) to 49% (2002), and the index of sexual risk behavior decreased from 0.98 in 1997 to 0.87, in 2002. The HIV infection prevalence rate was 0.09%, in 2002, which remained unchanged since1998 Riskier sexual practices among young men with incomplete education and among "men who h...

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. 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. 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.

AIDS and Behavior, 2002
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.
Syphilis prevalence and risk factors among young men presenting to the Brazilian Army in 2016
Medicine, 2018
The Conscripts Survey has been conducted periodically by the Brazilian Department of Sexually Transmitted Infections (STIs), AIDS, and Viral Hepatitis (DIAHV) in collaboration with the Brazilian Ministry of Defense for over 2 decades. It aims to assess the syphilis prevalence and obtain data on knowledge regarding STIs and their risk factors among conscripts enlisted for the Brazilian Army. This cross-sectional study was conducted among conscripts across Brazil aged 17 to 22 years from August to December 2016. It included a self-reported questionnaire and blood testing for syphilis, HIV, and hepatitis B and C. In total 38,247 conscripts were enrolled; after exclusion due to a lack of information, 37,282 (93.2%) conscripts were included. The estimated syphilis prevalence rates were: 1.63%, 1.09%, and 0.62% for screened, confirmed, and active syphilis, respectively. Among those with active syphilis, 81.1% reported not having syphilis infection in their lifetime. Higher confirmed syphilis prevalence rates were observed in the South region, followed by North and Southeast regions. Independent factors associated with confirmed syphilis infection were: self-reported STIs in one's lifetime (odds ratio [OR] = 7.24; P < .001), same-sex sexual relationships (OR = 3.43; P = .001), and having the 1st sexual intercourse encounter before 15 years of age (OR = 2.62; P = .04). The proportion of conscripts who reported having sex with other men (MSM) was 4.3%, and the estimated syphilis prevalence in this group was 5.23%, 4.61%, and 3.60% for screened, confirmed, and active syphilis, respectively. The sexual behaviors most frequently associated with confirmed syphilis were: sexual relationship with casual partners in the last year (P < .001), same-sex sexual relationships (P < .001), more than 10 partners (P = .006), and having sexual intercourse before 15 years of age (P = .003). Although not significant, only 25.4% of the conscripts who had a confirmed syphilis reported the use of condoms with steady partners, 32.4% with casual partner, and 24.3% with any partner. We found that syphilis is on the rise among the young Brazilian male population. The increase in its prevalence, particularly among MSM, highlights the need for urgent public health interventions, action plans, and implementation of risk reduction strategies aimed at this population.

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.
HIV infection and related risk behaviours in a disadvantaged youth institution of Sao Paulo, Brazil
International Journal of Std & Aids, 1999
In order to study the prevalence of HIV and related risky behaviours among disadvantaged youth, we interviewed and bled, between December 1994 and April 1995, 1122 young males and 93 young females who were serving time in FEBEM, a state institution that cares for homeless and offender youth of Sa Ä o Paulo, Brazil. Our questionnaire covered the following areas: sexual practices and use of illicit drugs; knowledge of HIV and STDs and their prevention; and myths and beliefs about AIDS. Seroprevalence of HIV was assessed and related with risktaking behaviours by means of uni-, bi-and multivariate analysis. We found 2.6% of the males and 10.3% of the females to be positive to HIV. The prevalence of hepatitis C virus (HCV) antibodies resulted in 5.9% for males and 4.6% for females, respectively. The risk for parenterally transmitted HIV among the males was higher than that for sexually related transmission. The inverse relationship was found among the females.
