Some research suggests that eating disorders are related to poor sleep health. To increase knowledge on the relation between sleep and eating disorders, we used a multi-method approach to examine associations between sleep, chronotype, and eating disorder psychopathology.
We investigated associations between ED psychopathology, both diagnostic categories (ascertained through self-report data) and dimensional measures, and self-report and ambulatory measures of sleep. Adults currently enrolled in a commercial weight loss program completed self-report measures as well as 1 week of ambulatory sleep monitoring and sleep diaries.
Participants with full- or sub-threshold bulimia nervosa and binge eating disorder reported significantly lower subjective sleep health and greater eveningness. Additionally, greater severity of eating disorder psychopathology was associated with lower subjective sleep health and greater eveningness. Eating disorder psychopathology was generally not related to objective sleep measures. Regarding diary measures, global eating disorder psychopathology was negatively correlated with subjective reports of feeling rested.
Eating disorder psychopathology is associated with participants' subjective sense of sleep quality, but appears to have little relation to objective sleep characteristics. Level of evidence Level V, descriptive study.
一些研究表明，饮食失调与睡眠健康不佳有关。为了增加对睡眠与饮食失调之间关系的了解，我们采用了多种方法来研究睡眠、昼夜节律类型与饮食失调精神病理学之间的关联。
我们调查了饮食失调精神病理学（包括诊断类别（通过自我报告数据确定）和维度测量）与睡眠的自我报告及动态测量之间的关联。目前参加商业减肥计划的成年人完成了自我报告测量以及为期1周的动态睡眠监测和睡眠日记。
患有完全或亚阈值神经性贪食症和暴饮暴食症的参与者报告主观睡眠健康状况明显较差，且更倾向于晚睡型。此外，饮食失调精神病理学的严重程度越高，主观睡眠健康状况越差，且越倾向于晚睡型。饮食失调精神病理学通常与客观睡眠指标无关。关于日记测量，总体饮食失调精神病理学与感觉休息良好的主观报告呈负相关。
饮食失调精神病理学与参与者的主观睡眠质量感相关，但似乎与客观睡眠特征关系不大。证据级别：V级，描述性研究。
