Background: Both blood sera and risky behavior studies contribute to understand HIV infection dynamics and risk factors in specific populations. HIV prevalence estimate for Colombia is 0.7%. The city of Popayan has a population of 260.000, 64.23% in the low SES with possible increased vulnerability to infection. This study pursued to determine HIV presence, socio-demographic characteristics, history of STDs and risk behaviors in healthy people of low SES.
Methods: Cross-sectional study; 358 participants of Popayan signed informed consent and received pre/post HIV test counseling. There were assessed socio-demographic characteristics; and history of STDs, risk behaviors and previous HIV testing. Descriptive statistics, correlations and multivariate logistic regression were calculated using Stata® Version 9.
Results: Mean age 33,5 ± 10,2; range age 18-64; 66% women; 40% had no stable partner; 21% had a positive history of STDs; 13% drank more than 5 heavy drinks or bottles of beer in two hours; 27% had more than two sexual partners during last year; 6% consistently used condom; and 13% had history of anal sex. HIV+ prevalence was 3.83% (IC95:1.87-5.85); greater in men (7.38%; p=0,013). People age 29-37 had greater frequency of HIV+ results versus age < 29 (p=0.025); those without a stable partner had 2.82 greater probability of an HIV+ test (p=0.029); those with history of more than five drinks in 2 hours had 6.55 greater frequency of being HIV+ in comparison to those who did not drink alcohol.
Conclusions: The global HIV prevalence in this population is greater than national estimate for general population, age 15-49, in Colombia (0.7%), with even greater frequency in men. It suggests that vulnerability associated low SES, in economically active population, without a stable partner and with risky alcohol use, can potentially increase risk of HIV infection.
