National Health & Aging Trends Study (NHATS)

Established in 2011, the National Health and Aging Trends Study (NHATS) is a longitudinal study that conducts annual in-person interviews with a nationally representative sample of Medicare beneficiaries ages 65 or older. Designed as a platform for scientific study of late life disability trends and trajectories, NHATS fosters research to guide efforts to reduce disability, maximize health and independent functioning, and enhance quality of life at older ages. The sample is refreshed periodically so that researchers may study national-level disability trends as well as individual trajectories. A Last Month of Life interview is conducted for deceased participants. Support for NHATS is provided by the National Institute on Aging. (https://www.nhats.org/researcher/nhats)
