  • Self-reported and Point-of-Care Biomarkers of Substance Use Measures Among Older Adults with HIV from Low- and Middle-Income Countries

    Open AccessKathryn E Lancaster, Melissa A Stockton et al.ARTICLEAIDS and Behavior2026

    Measuring alcohol and other drug (AOD) use remains challenging in HIV care in low- and middle-income countries, where self-report and point-of-care (POC) urine biomarkers capture different time windows. Among 2,059 people with HIV aged 40 years or older across eight IeDEA clinics (2020 to 2022), we examined what self-reported AOD use (AUDIT, ASSIST) and POC urine tests (uEtG for alcohol; 5-panel drug screen) each capture. Self-report identified m…

  • Effects of Alcohol Use on Patient Retention in HIV Care in East Africa

    Open AccessAlexa Monroy, Suzanne Goodrich et al.ARTICLEAIDS and Behavior2024

    We sought to investigate the association between hazardous alcohol use and gaps in care for people living with HIV over a long-term follow-up period. Adults who had participated in our previously published Phase I study of hazardous alcohol use at HIV programs in Kenya and Uganda were eligible at their 42 to 48 month follow-up visit. Those who re-enrolled were followed for an additional ~ 12 months. Hazardous alcohol use behavior was measured usi…

  • Effects of the Covid-19 pandemic on late postpartum women living with HIV in Kenya

    Open AccessJohn Humphrey, Marsha Alera et al.ARTICLEPLOS Global Public Health2023

    Although an estimated 1.4 million women living with HIV (WHIV) are pregnant each year globally, data describing the effects of the COVID-19 pandemic on postpartum women in low- and middle-income countries (LMICs) are limited. To address this gap, we conducted phone surveys among 170 WHIV ≥18 years and 18–24 months postpartum enrolled in HIV care at the Academic Model Providing Access to Healthcare in western Kenya, and assessed the effects of the…

  • Retention in care and viral suppression in the PMTCT continuum at a large referral facility in western Kenya

    Open AccessJohn Humphrey, Julia Songok et al.ARTICLEAIDS and Behavior2022

    Medical records of pregnant and postpartum women living with HIV and their infants attending a large referral facility in Kenya from 2015 to 2019 were analyzed to identify characteristics associated with retention in care and viral suppression. Women were stratified based on the timing of HIV care enrollment: known HIV-positive (KHP; enrolled pre-pregnancy) and newly HIV-positive (NHP; enrolled during pregnancy). Associations with retention at 18…

  • A qualitative study of the barriers and enhancers to retention in care for pregnant and postpartum women living with HIV

    Open AccessJohn Humphrey, Danièle Maubon et al.ARTICLEPLOS Global Public Health2021

    Retention in care is a major challenge for pregnant and postpartum women living with HIV (PPHIV) in the prevention of mother-to-child HIV transmission (PMTCT) continuum. However, the factors influencing retention from the perspectives of women who have become lost to follow-up (LTFU) are not well described. We explored these factors within an enhanced sub-cohort of the East Africa International Epidemiology Databases to Evaluate AIDS Consortium. …

  • Association of Health Status and Nicotine Consumption with Sars-CoV-2 positivity rates

    Open AccessThomas J Duszynski, William F Fadel et al.ARTICLEBMC Public Health2021

    In a statewide, community-based population drawn for SARS-CoV-2 testing, we find that overall health status was associated with infection rates. Unlike in studies of COVID-19 patients, smoking status was inversely associated with SARS-CoV-2 positivity. More research is needed to further understand the nature of this relationship
