National Health and Aging Trends Study

Description: 

The National Health and Aging Trends Study (NHATS) is a new resource for the scientific study of functioning in later life. The NHATS is being conducted by the Johns Hopkins University Bloomberg School of Public Health, with data collection by Westat, and support from the National Institute on Aging. In design and content, NHATS is intended to foster research that will guide efforts to reduce disability, maximize health and independent functioning, and enhance quality of life at older ages. The NHATS will gather information on a nationally representative sample of Medicare beneficiaries ages 65 and older. In-person interviews will be used to collect detailed information on activities of daily life, living arrangements, economic status and well-being, aspects of early life, and quality of life

Methodology: 
The National Health and Aging Trends Study (NHATS) follows a sample of over 8,000 Medicare beneficiaries ages 65 and older through annual in-person data collection. Round 1 of the study was fielded in 2011. The NHATS sample design is age-stratified so that persons are selected from 5 year age groups between the ages of 65 and 90, and from among persons age 90 and older. The design oversamples persons at older age groups and persons whose race is listed as Black on the CMS enrollment file. Replenishment of the sample to maintain the ability to represent the older Medicare population is planned at regular intervals.
