Associations between neighborhood characteristics and sexual risk behaviors among HIV-infected and HIV-uninfected women in the southern United States.

ABSTRACT: PURPOSE:Neighborhood characteristics shape sexual risk in HIV-uninfected adults in the United States (US). We assess relationships between census tract characteristics and sexual risk behaviors in a predominantly HIV-infected cohort of women living in the Southern US. METHODS:This cross-sectional multilevel analysis included data from 737 HIV-infected and HIV-uninfected women enrolled in the Women's Interagency HIV Study. Administrative data captured characteristics of census tracts where women lived; participant-level data were gathered via survey. We used principal components analysis to condense tract-level variables into components: social disorder (e.g., violent crime rate), and social disadvantage (e.g., alcohol outlet density). We used hierarchical generalized linear models to assess relationships between tract-level characteristics and condomless vaginal intercourse, anal intercourse, and condomless anal intercourse. RESULTS:Greater social disorder was associated with less anal intercourse (OR = 0.63, 95% CI = 0.43-0.94) and condomless anal intercourse (OR = 0.49, 95% CI = 0.30-0.80), regardless of HIV status. There were no statistically significant additive or multiplicative interactions between tract characteristics and HIV status. CONCLUSIONS:Neighborhood characteristics are associated with sexual risk behaviors among women living in the Southern US, these relationships do not vary by HIV status. Future studies should establish temporality and explore the causal pathways through which neighborhoods influence sexual risk.

Project description:BackgroundHIV infection and its management confer a substantial health burden to affected individuals and have been associated with increased risk of oral and dental diseases. In this study, we sought to quantify HIV-associated differences in the prevalence and severity of dental caries in the primary and permanent dentition of 4-11-year-old Nigerian Children.MethodsWe used clinical, laboratory, demographic, and behavioral data obtained from an ongoing cohort study of age-matched HIV-infected (HI, n = 181), HIV-exposed-but-uninfected (HEU, n = 177), and HIV-unexposed-and-uninfected (HUU, n = 186) children. Measures of dental caries experience (i.e., prevalence and severity) were based on dmft/DMFT indices recorded by trained and calibrated clinical examiners. Differences in primary and permanent dentition caries experience between HI, HEU, and HUU were estimated using multivariable logistic and negative binomial regression modeling.ResultsHI children had significantly higher caries experience (33%) compared to HEU (15%) and HUU (22%) children. This difference persisted in fully adjusted analyses [odds ratio (OR) = 1.6; 95% confidence interval (CI) = 1.0-2.6], was most pronounced in the permanent dentition (OR = 3.4; 95% CI = 1.2-9.5), and mirrored differences in caries severity. While molars were predominantly affected in both primary and permanent dentitions, caries lesion patterns differed between dentitions. Caries severity was significantly associated with hypoplastic primary teeth, gingival inflammation, and lower CD4 counts.ConclusionsWe found that the higher prevalence and severity of dental caries among HI children was driven by increased burden of permanent dentition caries compared to their uninfected counterparts. The dentition-specific associations identified in this study highlight the need to design and implement age-specific caries prevention strategies. These may include intensified oral hygiene regimens aimed at mitigating the cariogenic impact of hyposalivation among HI children. Similarly, the long-lasting impacts of developmental defects of the enamel in the primary and permanent dentitions must not be ignored.

Project description:BACKGROUND:Cardiovascular disease is emerging as a major cause of morbidity and mortality among patients with HIV. We compared use of national guideline-recommended cardiovascular care during office visits among HIV-infected versus HIV-uninfected adults. METHODS AND RESULTS:We analyzed data from a nationally representative sample of HIV-infected and HIV-uninfected patients aged 40 to 79 years in the National Ambulatory Medical Care Survey/National Hospital Ambulatory Medical Care Survey, 2006 to 2013. The outcome was provision of guideline-recommended cardiovascular care. Logistic regressions with propensity score weighting adjusted for clinical and demographic factors. We identified 1631 visits by HIV-infected patients and 226 862 visits by HIV-uninfected patients with cardiovascular risk factors, representing ?2.2 million and 602 million visits per year in the United States, respectively. The proportion of visits by HIV-infected versus HIV-uninfected adults with aspirin/antiplatelet therapy when patients met guideline-recommended criteria for primary prevention or had cardiovascular disease was 5.1% versus 13.8% (P=0.03); the proportion of visits with statin therapy when patients had diabetes mellitus, cardiovascular disease, or dyslipidemia was 23.6% versus 35.8% (P<0.01). There were no differences in antihypertensive medication therapy (53.4% versus 58.6%), diet/exercise counseling (14.9% versus 16.9%), or smoking cessation advice/pharmacotherapy (18.8% versus 22.4%) between HIV-infected versus HIV-uninfected patients, respectively. CONCLUSIONS:Physicians generally underused guideline-recommended cardiovascular care and were less likely to prescribe aspirin and statins to HIV-infected patients at increased risk-findings that may partially explain higher rates of adverse cardiovascular events among patients with HIV. US policymakers and professional societies should focus on improving the quality of cardiovascular care that HIV-infected patients receive.
