Prevalence of sexually transmitted infections and associated risk behaviors in prisoners: A systematic review

Background and aims: Sexually transmitted infections (STIs) are one of the major health concerns globally. Generally, prisoners are at higher risks for STIs due to risk factors including; drug-use, high-risk sexual behaviors, densely populated prisons, and poor living conditions. Therefore, we aimed to conduct a systematic review to evaluate the existing data on STI prevalence, and its associated risk factors among prisoners.

Methods: We conducted a systematic search of the literature using the keywords in Scopus, PubMed, Web of Science, and Google Scholar online databases. We selected all the relevant original studies in English through title/abstract and full-text screening process.‎.

Results: Based on the inclusion and exclusion criteria, we selected and reviewed 32 studies out of 96 identified papers. The most important STI-associated risk factors among prisoners were drug use, low educational levels, and unsafe sex. The prevalence of STIs was heterogenous in selected studies and was reported as follows; Human Immunodeficiency Virus (HIV) (0%–14.5%), hepatitis B viruses (HBV) (0.04%–27.23%), hepatitis C viruses (HCV) (0.17%–49.7%), Syphilis (0.2%–22.1%), Chlamydia Trachomatis (CT) (1.02%–6.7%), Gonorrhea (0.6%–7.8%), and herpes simplex virus-2 (HSV-2) 22.4%.

Conclusion: This systematic review indicates that the prevalence of STIs (HIV, HBV, HCV, Syphilis, Chlamydia Trachomatis, Gonorrhea, and HSV-2) among prisoners appears to be higher than the general population, with drug abuse, low educational levels, and unsafe sex as major risk factors.
