Health Behavior in School-Age Children: NEXT Longitudinal Study 2009-2016

April 24, 2024 updated by: Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)

NEXT is a seven-year longitudinal assessment of a representative sample of U.S. adolescent and young adults starting at grade 10. The goals of the NEXT longitudinal study include: to identify the trajectory of adolescent health status and health behaviors from mid-adolescence through the post high school years; to examine individual predictors of the onset of key adolescent risk behaviors and risk indicators during this period; to identify genetic, personal, family, school, and social/environmental factors that promote or sustain positive health behaviors; to identify transition points in health risk and risk behaviors and changes in family, school, and social/environmental precursors to these transitions, and to examine the role of potential gene-environment interactions in the development of health status and health behaviors. .

This study collects reliable and valid data on health behaviors and health indicators and their social, environmental, and biological contexts beginning with a nationally representative probability cohort of 10th-grade children in the U.S in 2009 and following them through 2016. Measures are collected annually for seven years beginning in the 2009-2010 school year and ending in the 2016-2017 school year. African-American youth are oversampled to provide better population estimates of this group and to provide an adequate sample to examine racial/ethnic differences in longitudinal predictors of health, health behaviors, and health behavior change. Hispanic youth do not require oversampling because they currently represent a sufficient proportion of the population of adolescents to provide an adequate sample to examine racial/ethnic differences. Self-reports of health status, health behaviors, and health attitudes are collected by in-school and online surveys. Anthropometric data, genetic information, and neighborhood characteristics are gathered on all participants as well. The study also incorporates an Administrator Survey and other data sources to obtain related information on school-level health programs and community-level contextual data. The NEXT Generation Health Study data support NICHD, National Heart, Lung and Blood Institute (NHLBI), National Institute on Drug Abuse (NIDA), National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the Maternal and Child Health Branch of the Health Resources and Services Administration (HRSA/MCHB) in fulfillment of program requirements that address supportive health environments for adolescents and young adults. In addition, a representative subsample of overweight and normal weight adolescents has been identified: additional data on behavioral risk factors and biological markers and risk factors are gathered on these adolescents. Driving performance will also be evaluated in 150 young adults.

Study Population

This study will include two phases. Phase 1 will include a secondary data analysis with emerging adults and peer driving data acquired from the NEXT Longitudinal Study collected by the National Institute of Child Health and Human Development (NICHD) at the NIH. Phase 2 will include conducting qualitative data collection through 4-5 focus groups on University of Maryland College Park (UMCP) campus with undergraduate students (age 18-22) to understand the influential factors associated with social norms on distracted driving
