Objectives. We examined the link between incarceration and sexually transmitted
infection (STI), including HIV, from a social network perspective.
Methods. We used data collected during a social network study conducted in
Brooklyn, NY (n=343), to measure associations between incarceration and
infection with herpes simplex virus-2, chlamydia, gonorrhea, and syphilis or
HIV and sex with an infected partner, adjusting for characteristics of respondents
and their sex partners.
Results. Infection with an STI or HIV was associated with incarceration of less
than 1 year (adjusted prevalence ratio [PR]=1.33; 95% confidence interval
[CI]=1.01, 1.76) and 1 year or longer (adjusted PR=1.37; 95% CI=1.08, 1.74).
Sex in the past 3 months with an infected partner was associated with sex in
the past 3 months with 1 partner (adjusted PR=1.42; 95% CI=1.12, 1.79) and with
2 or more partners (adjusted PR=1.85; 95% CI=1.43, 2.38) who had ever been
Conclusions. The results highlight the need for STI and HIV treatment and
prevention for current and former prisoners and provide preliminary evidence to
suggest that incarceration may influence STI and HIV, possibly because incarceration
increases the risk of sex with infected partners.
