Background: Behavioral surveillance surveys have been carried out among military conscripts, in Brazil, since 1996. This paper presents the results of the 2007 survey and compares current findings with those obtained in previous studies carried out in the period 1999-2002.
Methods: The conscripts were selected with a two stage sampling process stratified by geographical region. The study included a self-reported questionnaire and blood collection for HIV and syphilis testing.
Results: Data from 35432 conscripts aged 17-20 years old were analyzed. The findings show a reduction in regular condom use, with regular and casual partners, mainly among those with low educational level. The proportion of conscripts that had had sex with men (MSM) was maintained (3.2%), but the sexual behavioral risk index was higher in this group, indicating an increase in risk behaviors. Also, the HIV prevalence rate increased from 9 per 10000 in 2002 to 11.3 in 2007. The increase was not statistically significant.
Conclusions: In conclusion, the evidence found in this paper indicates the need to improve prevention policy among young adults. In general, the Brazilian response to the HIV/AIDS epidemic has achieved positive results. However, the response may not be homogenous, since we observe a slight increase in HIV prevalence when considering the point estimates, in males aged 17-20. Furthermore, in the last five years, a raise in risk behavior, including decrease in condom use, has been seen in this population. In conclusion, the evidence found in this paper indicates the need to improve prevention policy among young adults.
