Health and Retirement Study Yrs 23-28: Venous Blood 2016
Funding: National Institute on Aging, 2015-2017 (3 U01 AG 009740 26 S4)
The primary aim of the Health and Retirement Study (HRS) cooperative agreement is to collect and distribute multi-disciplinary data to support research on aging. Because of their value in assessing health status and elucidating pathways connecting social experience to health, biomarkers have become a key element of the HRS approach to measurement. This project aims to build on this foundation and augment the biomarker component of the current HRS renewal cycle by collecting samples of venous blood from participants in the longitudinal study. A selective set of assays will be performed on samples and data released to the research community. These assays will enhance harmonization with other large population studies of aging and independently advance research on mechanisms of social disparities in health and aging. Blood assays are able to provide information on the aging of the immune system and related molecular and cellular age-related changes, illuminating some of the mechanisms underlying differences in aging for social and demographic subgroups.
