National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave V, 2016-2018

Wave V was conducted during 2016-2018 to collect social, environmental, behavioral, and biological data with which to track the emergence of chronic disease as the cohort advanced through their fourth decade of life. The Wave V design included a mixed-mode survey. An in-home interview was administered to a sub-sample of respondents to analyze mode effects. Repeat anthropometric, cardiovascular, metabolic, and inflammatory measures indicative of the change in and/or onset of chronic disease, including obesity, hypertension, diabetes, and dyslipidemia were collected, along with new biomarkers of chronic kidney disease. The survey was expanded to obtain retrospective reports of birth and childhood circumstances to supplement existing early life data.
