Incidence rate ratios (IRR) and odds ratios (OR) and 95% confidence intervals (CI) for the relationship between criminal justice involvement (time 2) and subsequent sexual risk behaviors (time 3) with covariance adjustment (time 1) among men in methadone maintenance treatment programs, New York City (N = 356)
| Dependent variable: sexual HIV/STI risk behaviors: time 3 | ||||||
|---|---|---|---|---|---|---|
| Independent variable: criminal justice involvement: time 2 | Number of unprotected vaginal sex acts, past 30 days | Proportion unprotected vaginal sex acts, past 30 days | Proportion unprotected anal sex acts, past 30 days | More than one sexual partner, past 6 months | Sex with someone HIV+ or IDU, past 6 months | Participant engaged in sex trading, past 6 months |

Adjusted models include the following time 1 covariates: age, race/ethnicity, education, income, recent unemployment, recent homelessness, history of physical or sexual abuse, number of children, number of drugs used past 6 months, HIV status, recent diagnosis of an STI, BSI Global Severity Index, BSI Positive Symptom Total, BSI Psychoticism Subscale, and composite of sexual risk behaviors past 6 months
*p ≤ 0.05, **p ≤ 0.01
aPost hoc adjusted models also include covariance adjustment for time 1 number of unprotected vaginal sex acts
