Health Behavior in School-Age Children: NEXT Longitudinal Study 2009-2013

NEXT is a four-year longitudinal assessment of a representative sample of U.S. school children starting at grade 10 The goals of the U.S. NEXT longitudinal study include: to identify the trajectory of adolescent health status and health behaviors from mid-adolescent through the post high school year ;to examine individual predictors o f the on set of key adolescent risk behaviors and risk indicators during this period; to identify family, school, and social / environment factors that promote or sustain positive health behaviors and to identify transition points in health risk and risk behaviors and changes in family, school ,and social / environment precursors to the set transitions.

This study will collect reliable and valid data on health behaviors and their social and environmental contexts from students in a four-year longitudinal, nationally-representative

Probability sample of l0th-grade children in the U.S. Measures will be collected annually for four years beginning in the 2009-2010 school year. Hispanic and African - American youth will be over sampled to provide better population estimates of these groups and to provide an adequate sample to examine racial/ ethnic differences in longitudinal predictors o f health, health behaviors and health behavior change. Self-reports of health status health behaviors and health attitudes will be collected by in-school and online surveys. Anthropometic data, genetic information, and neighborhood characteristics will be gathered on all participants as well. The study will also incorporate an Administrator Survey and other data files to obtain related information on school-level health programs and community-level on textual data to support NICHD and the Maternal and Child Health Branch of the Health Resources and Services Administration ( HRSA/NICHB) in program requirements that address supportive health environments for adolescents. In. addition, a representative sub sample of overweight and normal weight adolescents will be identified: additional data on behavioral risk factors and biological markers and risk factors will be gathered on these adolescents.

African - American youth will be over sampled to provide better population estimates of these groups and to provide an adequate sample to examine racial/ ethnic differences in longitudinal predictors o f health, health behaviors and health behavior change. Hispanic yout will 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 will be collected by in-school and online surveys. Anthropometic data, genetic information, and neighborhood characteristics will be gathered on all participants as well.
