Retrospective cohort study on Korean adolescents’ sleep, depression, school adjustment, and life satisfaction

Abstract

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.

Prevalence and correlates of lifestyle behavior, anxiety and depression in Chinese college freshman: A cross-sectional survey

“…Night eaters have lower plasma melatonin and leptin levels and higher levels of plasma cortisol relative to non-night eaters [ 54 ], which may lead to impaired sleep. Studies have proved that sleep duration and sleep quality were negatively correlated with depression [ 46 , 55 , 56 ]. However, the relationship between frequency of eating in-between meal snacks and depression was not significant, which was consistent with Fulkerson et al.’s study [ 41 ].…”

Associations of sleep patterns with metabolic syndrome indices, body composition, and energy intake in children and adolescents

“…To examine the effects of short sleep on MetS indices, body composition, and EI, analyses of covariances were conducted with short sleep (<7 hours of sleep) and adequate sleep (≥7 hours of sleep) as the independent variables. Given the links for depressive symptoms with sleep, MetS indices, and EI in children [36–38], CDI total score was considered as a covariate in all models. As bedtimes differed between youth who wore an actigraph during the school year versus the summer break ( p <.001), time of assessment was also considered as a covariate in all models.…”

Associations of Weekday and Weekend Sleep with Children’s Reported Eating in the Absence of Hunger

“…Because sleep timing is known to have associations with excess weight [55], eating related cognitive control [25], and reward sensitivity [29], in exploratory analyses, all tests were re-analyzed using weekday versus weekend in–bed time and wake times rather than sleep duration. For all models, given the links of depressive symptoms with sleep in children [56,57], the depressive symptoms score was entered as a covariate. Additionally, all models were adjusted for age, sex (0 = male, 1 = female), race (1 = Non-Hispanic white, 0 = other), height (cm).…”
