Effects of Anxiety, Depression, and Stress on Sleep Disorder and Night Eating Syndrome in Adolescents: Results of an Internet Survey

Abstract PurposeThe current study examined how sleep quality is related to night eating syndrome (NES) via the indirect effects of anxiety, depression, and stress to determine the mechanism of its development. MethodsThis cross-sectional web-based study included 171 adolescents aged 12-18 years (55.0% girls). Participants completed the self-report Night Eating Questionnaire (NEQ), Scales for Outcomes in Parkinson’s disease (SCOPA) Sleep Scale, and Depression, Anxiety and Stress Scale–21 items (DASS-21). ResultsThe results showed that anxiety, depression, and stress directly influenced the NEQ. AMOS path analysis was used to examine whether these also had an indirect influence on the NEQ. Moreover, for the anxiety, depression, and stress subscales, only the anxiety subscale influenced nighttime eating problems due to increased sleep problems, which in turn increased the difficulty of morning sleepiness and falling asleep at night. ConclusionConsequently, depression and stress directly increased nighttime eating problems. Anxiety exacerbates eating problems, both directly and indirectly, through sleep. Behavioral and psychological interventions to reduce anxiety, depression, and stress may be helpful strategies for the treatment of night eating syndrome.Level of evidence: Level IV
