Add Health-National Longitudinal Study

Project: Add Health-National Longitudinal Study of Adolescent to Adult Health (Add Health): Wave VI Cognition and Early Risk Factors for Dementia Project

Grant Number: National Institute on Aging U01-AG071450

ADD Health is a nationally representative, longitudinal study of individuals primarily born from 1976 through 1982 who were first interviewed as adolescents in grades 7-12 (ages 12-19) in 1994-1995. To date, four waves of data have been collected at ages 13-20 (1996, Wave II), 18-26 (2001-2002, Wave III), 24-32 (2008, Wave IV), and 32 to 42 (2016-2018, Wave V). Add Health respondents are presently entering middle age, a time that may be critical for the emergence and progression of many health conditions and disparities as individuals grow older. Wave VI will collect and disseminate innovative data to thousands of researchers that will facilitate the rigorous study of cognition and risk factors for later life ADRD among a diverse nationally representative sample of early midlife Americans.
