We examined how purging behaviors relate to subjective sleep quality and sleep patterns and how symptoms of disordered eating behaviors relate to global sleep quality in female patients with anorexia nervosa (AN).
Participants were new consecutive female inpatients with a primary diagnosis of AN admitted to the Department of Psychosomatic Medicine at Kohnodai Hospital between June 26 and December 25, 2015. We recorded patients' habitual eating behaviors, laxative overuse, or uretic misuse, and administered the Japanese versions of the Pittsburgh Sleep Quality Index (PSQI-J) and Center for Epidemiologic Studies Depression Scale. Raw PSQI-J data were used to determine sleep patterns (sleep-onset time, wake-up time, and sleep duration). To examine how purging behaviors related to sleep quality, we compared variables between AN restricting type (ANr) and AN binge-eating/purging type (ANbp). Spearman's rank correlation analysis was used to examine which potential factors influence global PSQI-J score.
Participants were 20 patients, of whom 12 had ANbp. Two ANr patients (25%) had global PSQI-J scores greater than 5, compared to 9 ANbp patients (75%; < 0.05). Circadian rhythm disruption and abnormal sleep duration were significantly greater in ANbp patients than in ANr patients ( < 0.05). Global PSQI-J was significantly correlated with a diagnosis of ANbp ( = 0.525; < 0.05), vomiting ( = 0.561; < 0.05), and duration of illness ( = 0.536; < 0.05).
ANbp patients had worse global sleep quality and greater disrupted sleep than did ANr patients. This suggests that treatments focusing on sleep would be useful, especially for ANbp patients. Furthermore, vomiting and duration of illness should be considered essential factors related to impaired global sleep quality.

我们研究了清除行为与主观睡眠质量和睡眠模式之间的关系，以及饮食失调行为症状与神经性厌食症（AN）女性患者整体睡眠质量之间的关系。
参与者为2015年6月26日至12月25日期间连续入住小田医院身心医学科、初步诊断为AN的新入院女性患者。我们记录了患者的习惯性饮食行为、泻药过度使用或利尿剂滥用情况，并使用了匹兹堡睡眠质量指数日语版（PSQI-J）和流行病学研究中心抑郁量表。原始PSQI-J数据用于确定睡眠模式（入睡时间、起床时间和睡眠时间）。为了研究清除行为与睡眠质量之间的关系，我们比较了AN限制型（ANr）和AN暴饮暴食/清除型（ANbp）之间的变量。采用Spearman等级相关分析来研究哪些潜在因素会影响整体PSQI-J评分。
参与者为20名患者，其中12名患有ANbp。两名ANr患者（25%）的整体PSQI-J评分大于5，而9名ANbp患者（75%；P<0.05）。ANbp患者的昼夜节律紊乱和异常睡眠时间明显高于ANr患者（P<0.05）。整体PSQI-J与ANbp诊断（r=0.525；P<0.05）、呕吐（r=0.561；P<0.05）和病程（r=0.536；P<0.05）显著相关。
ANbp患者的整体睡眠质量比ANr患者更差，睡眠干扰更大。这表明专注于睡眠的治疗将是有用的，尤其是对于ANbp患者。此外，呕吐和病程应被视为与整体睡眠质量受损相关的重要因素。
