Mediating Pathways in Faith-Based Sexual Risk-Reduction for African American Adolescents
Assessing Mediation and Moderation of an Efficacious Physical Activity Intervention for African American Men Living with HIV
Do syndemic conditions predict HIV medication adherence among urban African American men
Much progress has been made in advancing antiretroviral (ART) adherence, yet disparities remain. To explore relationships of syndemic conditions - co-occurring health conditions caused by combinations of biological, social, and structural factors - to ART adherence among African American men, we used data from longitudinal assessments of 302 African American men enrolled in a study designed to increase physical activity and healthy eating. Syndem…
Acceptability, facilitators, and barriers to a hypothetical HIV vaccine in the pre-exposure prophylaxis era
Little is known about the pre-implementation context for a preventive HIV vaccine. We conducted interviews of individuals in Philadelphia recruited at Penn clinics and community-based organizations serving LGBTQ-identifying persons of color who 1) were cisgender men who had sex with men, or were transgender-identified, 2) had a sexually transmitted infection in the last 12 months, or sex with multiple partners within the last two weeks. We assess…

Physical Activity Intervention Effects on Waist-to-Hip Ratio in African American Men Living With HIV
People living with HIV on antiretroviral therapy have an increased risk of developing metabolic disturbances and central adiposity. Adequate engagement in physical activity (PA) could reduce the risk of chronic diseases associated with central adiposity. We conducted a secondary analysis of data from a randomized controlled trial of a PA intervention with 302 African American men aged 40 or older (53.9±7.2 years) living with HIV to assess whether…
Reasoned Action Approach Correlates of Fruit and Vegetable Diet Among African American Men Living With HIV
Epidemiological evidence of the protective role of fruits and vegetables for a host of chronic health conditions is well-documented. However, there is a dearth of studies examining predictors of fruit and vegetable intake among African American men living with HIV. We report secondary analyses—multiple regression and logistic regression models fitted to examine the strength of the relationships between the reasoned action approach constructs; nam…

The Effects of Three Types of Sexual Orientation Victimization on HIV Sexual Risk Behavior Among Black South African Men Who Have Sex With Men (MSM)
The goal of this study is to examine the relations between histories of three types of sexual orientation victimization (childhood, personal, and institutional) and HIV sexual risk behavior among Black South African men who have sex with men (MSM). Secondarily, this study examines whether marijuana use and problem drinking mediate the relations. Participants were 125 Black MSM recruited from neighborhoods in Eastern Cape Province, South Africa. Q…
Assessing the Acceptability of a Peer Mentor Mother Intervention to Improve Retention in Care of Postpartum Women Living with HIV
Background: Many women living with HIV (WLWH) experience poor postpartum retention in HIV care. There are limited evidence-based interventions in the United States aimed at increasing retention of WLWH postpartum; however, evidence from low-resource settings suggest that women who receive peer mentoring experience higher retention and viral suppression postpartum. Methods: We conducted 15 semistructured interviews with pregnant or postpartum wome…
HIV care continuum outcomes of pregnant women living with HIV with and without depression
Women living with HIV (WLWH) suffer from poor viral suppression and retention postpartum. The effect of perinatal depression on care continuum outcomes during pregnancy and postpartum is unknown. We performed a retrospective cohort analysis using HIV surveillance data of pregnant WLWH enrolled in perinatal case management in Philadelphia and evaluated the association between possible or definite depression with four outcomes: viral suppression at…
Development of a barbershop based violence intervention for young Black emerging adult men
A crucial gap in the education literature are the health interventions situated for the unique experiences of Black emerging adult men (BEAM), one of the most vulnerable populations in the United States The article describes the systematic development of a theory‐based, culturally tailored, barbershop‐based violence intervention for BEAM, aged 18–24 years. The process included developing a community advisory board, selecting a theoretical framewo…

Sub-Saharan African University Students' Beliefs about Abstinence, Condom Use, and Limiting the Number of Sexual Partners
Given the high risk of HIV infection among university students in sub-Saharan Africa, there is a need for culturally appropriate risk-reduction interventions specifically targeting this population. Efforts to reduce the risk require an understanding of the modifiable antecedents of sexual-risk behaviors. We report the results of a semi-structured elicitation survey based on the reasoned action approach to identify behavioral, normative, and contr…

Protective Factors and HIV Risk Behavior Among South African Men
Reductions in HIV risk-associated sexual behaviors among black male adolescents
BACKGROUND. The number of reported cases of acquired immune deficiency syndrome (AIDS) is increasing disproportionately among Blacks in the United States. The relatively high incidence of sexually transmitted diseases among Black adolescents suggest the need for AIDS prevention programs to reduce their risk of sexually transmitted human immunodeficiency virus (HIV) infection. METHODS. Black male adolescents (n = 157) were randomly assigned to rec…
Psychosocial factors, immunologic mediation, and human susceptibility to infectious diseases
Judging health status
In this article, we show that people's evaluations of the seriousness of a health disorder are influenced by the perceived prevalence and personal relevance of that disorder. As part of a study ostensibly concerned with college students' health characteristics, 60 undergraduates were "tested" for the presence of a fictitious enzyme deficiency. The subjects discovered either that they had the deficiency (deficiency-present subjects) or that they d…
Reducing HIV risk‐associated sexual behavior among african american adolescents
This randomized controlled trial tested the effects of a theory‐based culture‐sensitive HIV risk‐reduction intervention among 496 inner‐city African American adolescents (mean age = 13 years) and examined the generality of its effects as a function of the facilitator's race and gender and the gender composition of the intervention group. Adolescents who received the HIV risk‐reduction intervention expressed more favorable behavioral beliefs about…
From rarity to evaluative extremity
Experiments showed a scarcity principle in evaluative judgments such that the identical characteristic is evaluated more extremely the lower its perceived prevalence. In Study 1, Ss evaluated a fictitious medical condition that was described as either beneficial or detrimental to health and as occurring in either 30% or in one half of 1% of a test population. The condition was evaluated more extremely--as as a more positive health asset or a more…
Effects on Sexual Risk Behavior and STD Rate of Brief HIV/STD Prevention Interventions for African American Women in Primary Care Settings
Objectives. We tested the efficacy of brief HIV/sexually transmitted disease (STD) risk-reduction interventions for African American women in primary care settings. Methods. In a randomized controlled trial, 564 African American women recruited at a Newark, NJ, inner-city women’s health clinic were assigned to a 20-minute one-on-one HIV/STD behavioral skill-building intervention, 200-minute group HIV/STD behavioral skill-building intervention, 20…
Effectiveness of an HIV/STD Risk-Reduction Intervention for Adolescents When Implemented by Community-Based Organizations
Objectives. We evaluated the effectiveness of an HIV/STD risk-reduction intervention when implemented by community-based organizations (CBOs). Methods. In a cluster-randomized controlled trial, 86 CBOs that served African American adolescents aged 13 to 18 years were randomized to implement either an HIV/STD risk-reduction intervention whose efficacy has been demonstrated or a health-promotion control intervention. CBOs agreed to implement 6 inte…
Family Structure, Parental Strictness, and Sexual Behavior among Inner-City Black Male Adolescents
Family structure, parental strictness, and sexual behavior were examined among 200 Black male adolescents who completed an anonymous questionnaire. Adolescents who lived with both of their parents reported using condoms more consistently in the past year and were less likely to report fathering a pregnancy as compared with adolescents who did not live with both of their parents. Parental strictness was related to sexual behavior, but the relation…

The Reasoned Action Approach in HIV Risk-Reduction Strategies for Adolescents
Adolescents worldwide are at high risk for adverse consequences of sexual activity, including HIV, other sexually transmitted diseases, and unintended pregnancy. Effective intervention strategies are needed to address this risk. This article discusses the advantages of the reasoned action approach for developing such strategies, including the ability to integrate population-specific qualitative information with the approach to develop an interven…
Sexual Knowledge, Attitudes, and Risky Sexual Behavior among Inner-City Black Male Adolescents
Sexual knowledge, attitudes toward sex and contraception, contraception use, and sexual behavior were examined among 200 Black male inner-city junior and senior high school students who completed an anonymous questionnaire. Virtually all of the students (97%) reported having had coitus at least once. Most (78%o) reported not using any contraceptive during initial coitus, and a majority (54%) reported not using one during their most recent coitus.…
Academic stress, social support, and secretory immunoglobulin A
We examined the relation of academic stress and social support to salivary concentrations of secretory immunoglobulin A (S-IgA), an antibody class that plays an important role in mucosal defense against acute upper respiratory tract infections. We assayed whole, unstimulated saliva samples collected from 15 healthy undergraduates 5 days before their final exam period, during their exam period, and 14 days after their last final exam for S-IgA con…

Disclosure of HIV diagnosis to HIV-infected children in South Africa
Worldwide about 2.5 million children younger than 15 years of age are living with HIV, and more than 2.3 million of them live in sub-Saharan Africa. Antiretroviral therapy has reduced mortality among HIV-infected children, and as they survive into adolescence, disclosing to them their diagnosis has emerged as a difficult issue, with many adolescents unaware of their diagnosis. There is a need to build an empirical foundation for strategies to app…
Cattle for Wives and Extramarital Trysts for Husbands? Lobola, Men, and HIV/STD Risk Behavior in Southern Africa
Lobola is in many Southern African countries a tradition, which is expected to be adhered by anyone who is part or want to be part of the community. It is about paying respect to the elders, the family and the community. It is a significant element of marriage among many tribes and there are strict rules to adhere. In order to determine how much the actual fact of payment of lobola would influence the behavior of husbands and wives, we conducted …
