Description: The National Longitudinal Study of Adolescent Health (also known as Add Health, the Add Health Study, and the Add Health Survey) is a nationally representative study originally designed to examine how social contexts (such as families, friends, peers, schools, neighborhoods, and communities) influence teens' health and risk behaviors. The study is now examining how health changes over the course of early adulthood.

Population: Nationally representative sample of ~90,000 students in grades seven through 12 during the 1994-1995 school year initially selected. In-home interviews then conducted at four waves of data collection: baseline, one-year later, when the participants were age 18-26, and most recently in 2008 when the participants were age 24-32.

Periodicity: Data is no longer available, but it can potentially be accessed by contacting the data owners.
