Depressive symptoms mediate the association between loneliness and cognitive performance in women living with HIV
Loneliness is a risk factor for cognitive impairment, yet, its role in domain-specific cognitive performance and underlying mechanisms remain understudied in women living with HIV (WLWH). To assess whether depressive symptoms mediate associations between loneliness and global and domain-specific cognition, data were analyzed from 1621 WLWH participating in the Women's Interagency HIV Study, a multicenter, observational cohort conducted in the Uni…
Validation of an Extended Sexual Orientation and Gender Identity Measure in a Racially and Ethnically Diverse Cohort of People Living with or at Risk for HIV Infection
Despite becoming a routine part of clinical care, collection of sexual orientation and gender identity (SOGI) is not standardized, and common measures might not reflect the full range of LGBTQ+ experiences. In this study, we tested a novel expanded SOGI measure that addresses these concerns in a racially and ethnically diverse HIV cohort study. Participants ( N = 885) were randomized to complete either a common SOGI measure with fewer SOGI choice…
Predictors of worsening food security among women living with and without HIV and seronegative women during Covid-19
This study aimed to assess the prevalence, severity, predictors, and lived experiences of food insecurity among women enrolled in the Women’s Interagency HIV Study in the USA in 2020, at the height of the COVID-19 pandemic. We hypothesized that pre-existing socioeconomic and health-related disparities would heighten the risk of worsening food insecurity during the pandemic. The 10-item US Household Food Security Survey was administered to partici…
Neighborhood Violence and Safety
Neighborhood violence and safety concerns are associated with poor health outcomes including HIV acquisition/transmission, and possible lack of viral suppression. Using a cross-sectional analytic design, we determined the prevalence of neighbourhood violence and safety concerns among participants in the MACS WIHS Combined Cohort Study, a large US cohort of men and women with and without HIV. We used multivariable logistic regression to assess fac…
Financial, housing, food, and healthcare insecurities and their independent and joint associations with depressive symptoms and stress in a U.S. cohort of adults with and without HIV
Trends in Alcohol Use Before and During the Covid-19 Pandemic Among Women Living With and Without HIV in the United States (2017–2022)
Data on alcohol use trends in women living with HIV (WLWH) are lacking. We examine data collected before and across the COVID-19 pandemic (2014-2022) in WLWH and socio-demographically similar women living without HIV (WLWOH)(n = 1564; 67% WLWH) who self-reported alcohol use to establish and compare trends. Women were categorized into baseline groups based on use pattern from 10/2014 to 09/2017: abstinence (no alcohol at any visit), non-heavy drin…

Food Insecurity, Internalized Stigma, and Depressive Symptoms Among Women Living with HIV in the United States
Mixed‐Methods Study of Uptake of the Extension for Community Health Outcomes (Echo) Telemedicine Model for Rural Veterans With HIV
PURPOSE: Extension for Community Health Outcomes (ECHO) is a provider-level telemedicine model successfully applied to hepatitis C care, but little is known about its application to Human Immunodeficiency Virus (HIV) care. We performed a mixed-methods evaluation of 3 HIV ECHO programs in the Veterans Health Administration, focusing on uptake by primary care clinics and veterans. METHODS: Administrative data were used to assess program uptake, inc…
Food Insecurity is Associated with Poor HIV Outcomes Among Women in the United States
Association between Perceived Discrimination in Healthcare Settings and HIV Medication Adherence
Mechanisms for the Negative Effects of Internalized HIV-Related Stigma on Antiretroviral Therapy Adherence in Women
BACKGROUND: Internalization of HIV-related stigma may inhibit a person's ability to manage HIV disease through adherence to treatment regimens. Studies, mainly with white men, have suggested an association between internalized stigma and suboptimal adherence to antiretroviral therapy (ART). However, there is a scarcity of research with women of different racial/ethnic backgrounds and on mediating mechanisms in the association between internalized…
The association of self-perception of body fat changes and quality of life in the Women's Interagency HIV Study
Body fat changes are of concern to HIV-seropositive adults on highly active antiretroviral therapy (HAART). Studies examining the association of body fat changes and quality of life (QOL) in the setting of HIV infection have been conducted predominately in men. We examined the relationship of self-perceived body fat change with QOL among 1671 HAART-using HIV-seropositive women (mean age 40±8 years; 54% African-American, 24% reporting <95% HAART a…

Regional fat deposition and cardiovascular risk in HIV infection
HIV-infected individuals are at increased risk for cardiovascular disease (CVD) and lipodystrophy, but the relationship between regional adipose tissue (AT) depots and CVD risk is not well described. We determined regional AT volumes and CVD risk in an analysis of 586 HIV-infected and 280 control FRAM study subjects using whole-body magnetic resonance imaging (MRI) and the Framingham Risk Score (FRS). Median FRS and FRS >10% were higher in HIV th…
Self-Perception of Body Fat Changes and Haart Adherence in the Women’s Interagency HIV Study
Medically Eligible Women Who Do Not Use Haart
Objectives. We investigated the prevalence and characteristics of HIV-positive women who do not report highly active antiretroviral therapy (HAART) use. Methods. We analyzed HAART use among 1165 HIV-positive participants in the Women’s Interagency HIV Study. Results. Between October 1, 2000, and March 31, 2001, 254 women with clinical indications for HAART reported not using it, 635 reported HAART use, and 276 had no clinical indications. In mult…
