Sexual behavior, serological profile and use of psychoactive substances among sex workers

To analyze the prevalence of sexually transmitted infections (STIs) and the use of psychoactive substances among sex workers and their relationship with sexual behavior.

Cross-sectional study conducted in the interior of the state of Goiás, Brazil, with sex workers. Sexual behaviors were assessed and information on substance use was obtained through the Alcohol, Smoking and Substance Involvement Screening. Laboratory tests detected human immunodeficiency virus (HIV), syphilis, hepatitis B, and hepatitis C. Descriptive analyses, chi-square, and logistic regression were performed.

A total of 104 sex workers (88.4% women) participated in the study. The prevalence of STIs was HIV (1.9%), syphilis (14.4%), hepatitis B serological scar (3.8%), and hepatitis C (1.9%). Inconsistent condom use was reported by 64.4% of sex workers. The most prevalent patterns of substance abuse/dependence were tobacco (53.8%), alcohol (43.3%), cannabis (29.8%) and cocaine (26.9%). No significant associations were identified between condom use and substance use.

A high prevalence of syphilis, inconsistent condom use, and patterns of substance abuse/dependence were observed among sex workers. The findings reinforce the need for effective combined STI prevention strategies, harm reduction actions, and specific care interventions for this vulnerable population.
