Risk behaviors for sexually transmitted infections in noninjecting drug users: A cross-sectional study:

The objective of this study was to investigate risk behaviors for sexually transmitted infections (STIs) in noninjecting drug users (NIDUs), using STI diagnosis history as an indicator. A cross-sectional study was conducted in 323 NIDUs of two facilities for alcohol and/or drug dependence treatment in the Goias State, Central Brazil. All participants were interviewed about risk behaviors and STI history. Multivariable analysis was performed in order to identify predictors of STIs. Adjusted prevalence ratio (APR) with confidence intervals of 95% was obtained using a Poisson regression model. Prevalence of self-reported STIs in the previous 12 months was 25.4% (95% confidence interval [95% CI]: 21.0–30.4%). A multivariable model verified that age (APR: 1.01; 95% CI: 1.00–1.01), sexual contact with partners diagnosed with STIs (APR: 1.27; 95% CI: 1.12–1.45) and injecting drug users (IDUs) (APR: 1.14; 95% CI: 1.14; 95% CI: 1.01–1.31), exchange sex for money and/or drugs (APR: 1.12; 95% CI: 1.02–1.21), and a h...
