To better understand the eating patterns of persons with eating disorders.
This study investigated typical eating behavior (meal frequency and snacking) and atypical eating behavior among 311 community women with on-line questionnaires. Participants were classified with bulimia nervosa (BN; n =39), binge eating disorder (BED; n = 69), or controls (CON; n = 203).
In terms of typical eating behaviors, the BN group ate significantly fewer meals, particularly lunches, than the other two groups. Atypical eating, such as nibbling, eating double meals and nocturnal eating, was significantly more common in the eating disorder groups. More frequent breakfast consumption was associated with lower BMI in the BED and CON groups, and more frequent meal consumption was associated with less binge eating in the BED group only.
Our study revealed differences in typical and atypical eating patterns, and associations with weight and eating disorder behaviors among eating disorder and control groups.
更好地了解饮食障碍患者的饮食模式。
本研究通过在线问卷对 311 名社区女性进行了典型饮食行为(进餐频率和吃零食)和非典型饮食行为的调查。参与者分为神经性贪食症(BN;n =39)、暴食障碍(BED;n = 69)或对照组(CON;n = 203)。
在典型饮食行为方面,BN 组的进餐次数,特别是午餐,明显少于其他两组。非典型饮食行为,如小口吃、吃双份餐和夜间进食,在饮食障碍组中更为常见。BED 和 CON 组中早餐食用越频繁,BMI 越低,BED 组中进食越频繁,暴食行为越少。
本研究揭示了饮食障碍组和对照组在典型和非典型饮食模式方面的差异,以及与体重和饮食障碍行为的关联。
