Sexual risk behaviors in African American and Puerto Rican women: Impulsivity and self-control.

ABSTRACT: Millions of people are living with the human immunodeficiency virus (HIV). African American and Hispanic/Latino communities suffer the most severe burden of HIV in the US. The ultimate goal of this study was to better understand risk factors for this infection: Do impulsivity and self control operate independently or synergistically with respect to HIV sexual risk behaviors in women? An enhanced understanding of these risk factors may better inform future interventions. Among the total of 343 female participants, half were African American and the other half were Latina. Data in this study were collected in the area of New York City during 2014-2016, when the mean age of the participants was 39 years. Linear regression analyses were used to examine the associations of impulsivity and self control with HIV sexual risk behaviors. Impulsivity and self control were independently associated with most of the HIV sexual risk behaviors examined. In addition, the interaction terms between impulsivity and low self control were all significantly associated with each of the sexual risk behaviors. Prevention programs should consider incorporating the roles of impulsivity and self control simultaneously as related to HIV risk behaviors.

Project description:The ApoE ?4 allele is the most significant genetic risk factor for late-onset Alzheimer disease. The risk conferred by ?4, however, differs across populations, with populations of African ancestry showing lower ?4 risk compared to those of European or Asian ancestry. The cause of this heterogeneity in risk effect is currently unknown; it may be due to environmental or cultural factors correlated with ancestry, or it may be due to genetic variation local to the ApoE region that differs among populations. Exploring these hypotheses may lead to novel, population-specific therapeutics and risk predictions. To test these hypotheses, we analyzed ApoE genotypes and genome-wide array data in individuals from African American and Puerto Rican populations. A total of 1,766 African American and 220 Puerto Rican individuals with late-onset Alzheimer disease, and 3,730 African American and 169 Puerto Rican cognitively healthy individuals (> 65 years) participated in the study. We first assessed average ancestry across the genome ("global" ancestry) and then tested it for interaction with ApoE genotypes. Next, we assessed the ancestral background of ApoE alleles ("local" ancestry) and tested if ancestry local to ApoE influenced Alzheimer disease risk while controlling for global ancestry. Measures of global ancestry showed no interaction with ApoE risk (Puerto Rican: p-value = 0.49; African American: p-value = 0.65). Conversely, ancestry local to the ApoE region showed an interaction with the ApoE ?4 allele in both populations (Puerto Rican: p-value = 0.019; African American: p-value = 0.005). ApoE ?4 alleles on an African background conferred a lower risk than those with a European ancestral background, regardless of population (Puerto Rican: OR = 1.26 on African background, OR = 4.49 on European; African American: OR = 2.34 on African background, OR = 3.05 on European background). Factors contributing to the lower risk effect in the ApoE gene ?4 allele are likely due to ancestry-specific genetic factors near ApoE rather than non-genetic ethnic, cultural, and environmental factors.
