National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave VI, 2022-2025

The overall goal of Wave VI was to better understand life course trajectories, determinants, and consequences of critical dimensions of aging, health, and health disparities among U.S. early midlife adults. Participants were between the ages of 39 and 51, with an average age of 44. Wave VI data collection took place between 2022 and 2025. Beyond longitudinal survey measures, newly added questions included those on cumulative stress, discrimination, despair, work-life balance, memory, physical limitations, and caregiving. Wave VI of Add Health also included a home exam for consenting survey participants, which included anthropometric, cardiovascular, medications, and blood-based data collection.
