Introduction. Neighborhood characteristics shape sexual risk and sexually transmitted infections (STIs) in HIV-uninfected adults in the United States (US). This dissertation utilizes multilevel analyses to test relationships between census tract characteristics and sexual risk behaviors, sex partner risk, and testing positive for an STI in a predominantly HIV-infected cohort of women living in the southern US. Methods. This cross-sectional multilevel study analyzed data from 737 HIV-infected and HIV-uninfected women enrolled at the Womenâ€™s Interagency HIV Studyâ€™s southern sites. Administrative data (e.g., US Census) captured characteristics of the census tracts where women lived; individual-level data were gathered via survey. We used principal components analysis to condense tract-level variables into two components: social disorder (e.g., violent crime rate) and social disadvantage (e.g., alcohol outlet density). We used hierarchical generalized linear models to test relationships between tract characteristics and (1) sexual risk behaviors (unprotected vaginal intercourse [UVI], anal intercourse [AI], unprotected anal intercourse [UAI]); (2) sex partner characteristics (risk-level [e.g., lifetime history of injection drug use], non-monogamy); and (3) testing positive for a current STI (Chlamydia, gonorrhea, trichomoniasis, syphilis) and to assess whether these relationships varied by HIV status. Results. Greater tract-level social disorder was associated with less AI (OR=0.65, 95% CI=0.43, 0.96) and UAI (OR=0.50, 95% CI=0.31, 0.82), regardless of HIV status; less partner non-monogamy (OR=0.72, 95% CI=0.54, 0.96) among HIV-uninfected women; and greater partner non-monogamy (OR=1.20, 95% CI=0.96, 1.50) and partner risk (OR=1.41, 95% CI= 1.16, 1.72) among HIV-infected women. Greater tract-level social disorder was associated with more STIs (OR=1.34, 95% CI=0.99, 1.87), regardless of HIV status. Greater social disadvantage was associated with less partner non-monogamy (OR=0.73 95% CI=0.60, 0.96) and lower partner risk (OR=0.84, 95% CI=0.72, 0.97), but more STIs (OR=1.34, 95% CI=0.96, 1.86), regardless of HIV status. Perceived neighborhood cohesion was associated with lower partner risk (OR=0.84, 95% CI=0.70, 1.02), regardless of HIV status. Conclusion. Findings suggest that neighborhood characteristics may be associated with sexual behaviors, partner characteristics, and STIs among HIV infected and HIV uninfected Southern women. Future research should establish the temporality of relationships and explore pathways through which neighborhoods create vulnerability to STIs.
