Summary
The National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. Add Health combines longitudinal survey data on respondents' social, economic, psychological, and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioral, and biological linkages in health trajectories as the Add Health cohort ages through adulthood. The files contained in this component of the Add Health restricted data are the Wave I through Wave IV disposition files, and a file containing cause of death information for Add Health respondents reported deceased at Wave III (n=96) and Wave IV (n=126). The cause of death information was obtained from the National Death Index (NDI), 2007, which is produced by the National Center for Health Statistics (NCHS). The NDI uses the World Health Organization's (WHO) International Classification of Disease (ICD) codes to identify causes of death. The NDI dataset contains 3 variables and has 227 observations. The dataset identifies cause of death, as well as the number of days between the respondent's Wave I interview and the 2007 NDI reported date of death. Cf: http://doi.org/10.3886/ICPSR27034.v5
