Sexually transmitted infections in male prison inmates. Prevalence, level of knowledge and risky behaviours.

Data on the prevalence of sexually transmitted infections (STIs) and risk factors among incarcerated people are few and data about STIs awareness among inmates are even lacking. This study aimed to assess prevalence of STIs, risky behaviours and STIs level of knowledge in male inmates of the Casa Circondariale-Genova Marassi, the main penitentiary in Genoa, Italy. Between January and June 2019, 662 inmate medical records were retrospectively examined to obtain clinical and laboratory data about STIs. To investigate the inmate level of knowledge of STIs and their risky behaviours, 111consenting participants answered, anonymously, a written questionnaire. One hundred and twenty-two patients had at least one infectious disease when entered the prison: HIV (1.8%), HBV (2.7%), HCV (12.5%) and syphilis (1.3%). When asked to select from a list of diseases which ones they thought to be sexually transmitted, only 12% of the inmates answered correctly; most of them ignored which body fluids are at risk for HIV transmission, which STIs can induce tumors and if any vaccination exists to prevent STIs. Substance abuse was common among inmates that frequently exchanged needles for injecting drugs. To reduce the STIs incidence, it is necessary to target high-risk populations: everyone entering a prison should be offered a systematic screening of all STIs, including those currently neglected. Since STIs knowledge among inmates is poor and risky behaviours are diffuse, informative interventions in prison may provide an opportunity to educate such a high-risk population.
