Sleep patterns have an important role in the physical and psychological health of adolescents. In this study, we investigated the effects of sleep duration on depression, school adjustment, and life satisfaction of adolescents. A retrospective cohort study was conducted using secondary data on first and second grade students in middle schools from the Korean Children and Youth Panel Survey. Those who responded to all items about sleep were selected, and those who were within 30 min of sleep duration difference across 1 year were selected. Participants who had no change in variables of personal factors, parental factors, and family environment across 1 year were selected (n = 421). Longer total sleep duration and shorter weekend oversleeping had effects on lower depression, higher school adjustment, and greater life satisfaction after adjusting for personal factors, parental factors, and family environment. Therefore, we propose that school nurses assess adolescents’ sleep patterns and counsel and educate adolescents and their parents about the influence of sleep patterns on adolescents.
