Marital status and sexually transmitted infection risk among non-injection and injection drug users
BACKGROUND: In US general-population samples, being married is protective against sexual risk-taking and sexually transmitted infection (STI). Research on the potential for marriage to protect against STI risk in vulnerable populations is limited. METHODS: Using data collected during the baseline visit of the Neuro-HIV Prevention Study (N=275), we estimated adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for associations between marital status and biologically-confirmed infection with trichomoniasis among street-recruited drug users in Baltimore City, MD. We also evaluated differences in sexual risk behaviors by marital status that may account for infection differences. RESULTS: A high prevalence of trichomoniasis was observed among those who were married (32.1%), single (17.0%), and divorced (17.8%). In analyses controlling for age, gender, race, education, and past six month cigarette smoking, crack smoking, and binge drinking, those who were currently married had nearly three times the odds of trichomoniasis than single/never married individuals, the referent (AOR: 2.90, 95% CI: 1.04, 8.12). Being divorced was not associated with trichomoniasis (AOR: 1.13, 95% CI: 0.49, 2.61). Married individuals had a higher lifetime number of casual partners (mean: 17 partners) than single individuals (mean: 13 partners) and higher levels of partnership concurrency defined as a history of sex with several casual partners during a three month period (married: 10.0%, single: 1.8%; p<0.001). Condom use and partner's non-monogamy was not associated with marital status. CONCLUSIONS: STI treatment and prevention efforts should reach both married and unmarried individuals in populations at elevated risk of infection such as drug users.
