Conducted by the University of North Carolina at Chapel Hill and funded by the National Institutes of Health and the National Institute of Child Health and Human Development, this study has been ongoing since 1994, with data collection waves in 1994, 1996, 2001, and 2008. The study's findings have been published in numerous academic journals, including the Journal of Adolescent Health, American Journal of Public Health, and Social Science & Medicine.

Introduction

The National Longitudinal Study of Adolescent Health was designed to investigate the complex relationships between social environment, family structure, and health outcomes among adolescents and young adults. The study's principal investigator, Kathleen Mullan Harris, is a renowned sociologist and demographer who has published extensively on topics related to adolescent health, family dynamics, and social inequality. The study's advisory board includes prominent researchers from Harvard University, Stanford University, and the University of California, Los Angeles. The study has also collaborated with other major research projects, such as the National Longitudinal Survey of Youth and the Panel Study of Income Dynamics.

Methodology

The National Longitudinal Study of Adolescent Health employed a stratified sampling design to select a representative sample of middle schools and high schools in the United States. The study's sample consisted of over 20,000 students from 132 schools, including public schools, private schools, and charter schools. The study's data collection methods included in-person interviews, self-administered questionnaires, and anthropometric measurements. The study also used geographic information systems to analyze the relationships between neighborhood characteristics and health outcomes. The study's methodology has been influenced by other notable studies, such as the Framingham Heart Study and the Nurses' Health Study.

Data Collection

The National Longitudinal Study of Adolescent Health collected data on a wide range of topics, including socioeconomic status, family structure, peer relationships, mental health, and physical health. The study also collected biological samples, such as blood samples and saliva samples, to examine the relationships between biological markers and health outcomes. The study's data collection waves were conducted in 1994, 1996, 2001, and 2008, with a response rate of over 80% for each wave. The study's data management and data analysis were conducted using statistical software packages, such as SAS and Stata. The study has also collaborated with other research projects, such as the National Health and Nutrition Examination Survey and the Youth Risk Behavior Surveillance System.

Key Findings
