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 Goiás 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 history of sexual violence (APR: 1.04; 95% CI: 1.04–1.32) were predictors of STIs. Elevated rates of STI history and risk behaviors were observed in NIDUs, supporting the vulnerability of this group for these infections. Public policies and health outreach should be intensified in this population, principally regular STI testing of individuals in treatment for drug dependence and their sexual partners.
