This paper reports human immuno-deficiency virus (HIV) prevalence in the 2nd National Biological and Behavioral Surveillance Survey
(BBSS) among men who have sex with men (MSM) in 12 cities in Brazil using respondent-driven sampling (RDS).
Following formative research, RDS was applied in 12 cities in the 5 macroregions of Brazil between June and December 2016 to
recruit MSM for BBSS. The target sample size was 350 per city. Five to 6 seeds were initially selected to initiate recruitment and
coupons and interviews were managed online. On-site rapid testing was used for HIV screening, and confirmed by a 2nd test.
Participants were weighted using Gile estimator. Data from all 12 cities were merged and analyzed with Stata 14.0 complex survey
data analysis tools in which each city was treated as its own strata. Missing data for those who did not test were imputed HIV+ if they
reported testing positive before and were taking antiretroviral therapy.
A total of 4176 men were recruited in the 12 cities. The average time to completion was 10.2 weeks. The longest chain length
varied from 8 to 21 waves. The sample size was achieved in all but 2 cities.
A total of 3958 of the 4176 respondents agreed to test for HIV (90.2%). For results without imputation, 17.5% (95%CI: 14.7?20.7)
of our sample was HIV positive. With imputation, 18.4% (95%CI: 15.4?21.7) were seropositive.
HIV prevalence increased beyond expectations from the results of the 2009 survey (12.1%; 95%CI: 10.0?14.5) to 18.4%; CI95%:
15.4 to 21.7 in 2016. This increase accompanies Brazil?s focus on the treatment to prevention strategy, and a decrease in support for
community-based organizations and community prevention programs. |
