IMPAACT 2046 / UPLIFT Study

IMPAACT 2046/UPLIFT (Understanding Practices of Lactation and Infant Feeding decisions Together with women with HIV) is a multi-site, mixed-methods, observational cohort study. The purpose of the study is to explore infant feeding preferences, practices, and outcomes among mothers with HIV and their families in the United States. It will employ both qualitative and quantitative research methods to address existing knowledge gaps and to understand the clinical, behavioral, and social factors influencing infant feeding decisions. As part of the study’s mixed method approach, a longitudinal cohort study of mothers and their infants will be established. The study also aims to pilot a national registry of breastfeeding women living with HIV in the United States. Site selection was completed in February 2025 and was opened to IMPAACT sites located in the United States, in accordance with its CDC grant funding specifications.
