OBJECTIVES
Evidence suggests that while objective binge eating (OBE) and subjective binge eating (SBE) differ in the amount of food consumed, both are associated with impairment in people with eating disorders. However, only OBE is accounted for in the diagnostic criteria of eating disorders. This study compared the sociodemographic profile and burden of OBE versus SBE at a population level.
DESIGN
Population-based survey.
PARTICIPANTS
A representative sample of 3028 men and women. Participants were categorised into four groups based on their reporting of binge eating in the past 3 months: non-binge eating group (no OBE or SBE), OBE group, SBE group and OSBE group (both OBE and SBE).
OUTCOME MEASURES
Demographics (age, genderand body mass index, BMI), binge eating, distress, weight/shape overvaluation and health-related quality of life. Groups were compared on sociodemographic information, overvaluation and health-related quality of life. The OBE and SBE groups were also compared on the distress related to binge eating.
RESULTS
No differences were found between the SBE group and OBE group in age, gender, BMI, mental health-related quality of life and overvaluation (all p>0.05). However, differences were found in the OSBE participants, namely that they were younger, had a higher mean BMI, lower mental health-related quality of life and higher overvaluation of weight/shape than the non-binge-eating participants (all p<0.001). Proportions of participants who reported distress related to binge eating in the OBE and SBE groups also did not differ (p=0.678).
CONCLUSION
There is little difference in the demographic profile or burden of people who engage in OBE versus SBE, supporting the proposed inclusion of SBE in the diagnostic criteria for eating disorders in International Classification of Diseases-11. People who experience both OBE and SBE may experience a relatively higher eating disorder severity and impairment.
目的
有证据表明，尽管客观暴食（OBE）和主观暴食（SBE）在摄入的食物量上有所不同，但两者都与饮食障碍患者的功能障碍有关。然而，只有 OBE 被纳入饮食障碍的诊断标准。本研究在人群水平上比较了 OBE 与 SBE 的社会人口统计学特征和负担。
设计
基于人群的调查。
参与者
3028 名男性和女性的代表性样本。根据他们在过去 3 个月报告的暴食情况，将参与者分为四组：非暴食组（无 OBE 或 SBE）、OBE 组、SBE 组和 OSBE 组（同时有 OBE 和 SBE）。
结果
在年龄、性别和体重指数（BMI）、暴食、苦恼、体重/体型过度重视和健康相关生活质量方面，SBE 组和 OBE 组之间没有差异（均 P>0.05）。然而，在 OSBE 参与者中发现了差异，即他们更年轻，BMI 均值更高，心理健康相关生活质量更低，对体重/体型的过度重视程度更高，而非非暴食参与者（均 P<0.001）。报告与暴食相关苦恼的 OBE 和 SBE 组参与者的比例也没有差异（P=0.678）。
结论
从事 OBE 与 SBE 的人的人口统计学特征或负担几乎没有差异，支持将 SBE 纳入国际疾病分类第 11 版中的饮食障碍诊断标准的建议。经历 OBE 和 SBE 的人可能会经历相对更高的饮食障碍严重程度和功能障碍。
