The study involved 4,494 adolescents between 12 and 18 years of age at the beginning of the study, and 3,582 young adults between the ages of 18 and 25 years in a six-to-seven year follow up. One-hundred and forty-five U.S. middle, junior and high schools were selected to participate based on size, school type, census region, level of urbanization, percentage of Caucasian and African-American students, grade span and curriculum. Health-related variables such as height, weight, pubertal development, mental health status, and chronic and disabling conditions were obtained through in-home interviews and self-report.
Adolescents who reported having trouble falling asleep every day or almost every day were categorized as having insomnia symptoms. Binge drinking was defined as drinking five or more alcoholic beverages in a row, and suicide ideation was based on whether or not a participant had endorsed having thoughts of suicide in the last year.
