The purpose of this investigation was to study the sleep-wake rhythm characteristics of young persons with food addiction (FA) and symptoms of depression. A total of 2,360 young persons living in northern European Russia were included in the study. The average age of the respondents (± standard deviation [SD]) was 17.9 [4.6] years (66.6% female). Each participant provided personal data and filled in three questionnaires: the Munich Chronotype Questionnaire, the Zung Self-Rating Depression Scale, and the Yale Food Addiction Scale. FA was detected in 8.9% of respondents, and moderate-to-severe symptoms of depression were detected in 16.7% of respondents. FA and depressive symptoms were more often detected in females. Age and body mass index were shown to be significantly associated with FA. There were positive associations between the time of sunrise and FA and depressive symptoms. Persons who had symptoms of depression also tended to have a later chronotype, lower sleep efficiency, later sleep onset, higher sleep inertia, and greater sleep latency on school days. A positive relationship between FA and the time of sleep onset on school days was also revealed. Thus, the results indicate that prolonged wakefulness in the evening after sunset was associated with FA.
本研究旨在探讨有进食障碍（FA）和抑郁症状的年轻人的睡眠-觉醒节律特征。共有 2360 名居住在北欧俄罗斯的年轻人参与了这项研究。受访者的平均年龄（±标准差[SD]）为 17.9[4.6]岁（66.6%为女性）。每位参与者提供个人数据并填写了三份问卷：慕尼黑昼夜类型问卷、zung 自评抑郁量表和耶鲁食物成瘾量表。在受访者中，8.9%被检测出有 FA，16.7%被检测出有中重度抑郁症状。女性中更常检测到 FA 和抑郁症状。年龄和体重指数与 FA 显著相关。日出时间与 FA 和抑郁症状呈正相关。有抑郁症状的人也往往有较晚的昼夜类型、较低的睡眠效率、较晚的入睡时间、较高的睡眠惯性和更长的睡眠潜伏期在上学日。还揭示了 FA 与上学日入睡时间之间的正相关关系。因此，研究结果表明，日落后天亮后晚上的清醒时间延长与 FA 有关。
