To identify psychological characteristics and eating behaviors associated with weight cycling and binge eating behaviors in overweight women (body mass index > 27.3).
Questionnaires measuring self-esteem, self-efficacy, coping strategies, psychological symptoms, depression, binge eating, restrained eating, disinhibition, and hunger were administered to female weight cyclers who were overweight. Psychological characteristics were compared between subjects grouped by binge eating disorder classification and by binge eating severity.
A convenience sample of 62 female weight cyclers who were overweight was recruited from the Chicago, Ill, area. Questionnaires were administered individually or in small groups in subjects' homes or other private settings.
Student's t tests or Mann-Whitney U tests were used to assess differences in psychological characteristics.
Thirty-six weight cyclers (58%) met the criteria for binge eating disorder and 26 (42%) did not. Weight cyclers with binge eating disorder reported greater severity of binge eating (P < .0005) and disinhibition (P < .0005) and poorer eating self-efficacy (P < .0005) than weight cyclers without binge eating disorder. Weight cyclers with severe binge eating behaviors reported greater psychological distress (P < .0005) and depression (P < .005) and lower self-esteem (P = .0001) and used less healthful coping strategies (P = .0027) than weight cyclers with no binge eating to moderate binge eating problems. Weight cyclers with severe binge eating behavior also reported more hunger (P < .0005) and used less cognitive restraint (P = .0024) than those with no binge eating to moderate binge eating problems.
Operational definitions of weight cycling and binge eating are needed to facilitate research on effective weight-loss treatments. Persons seeking to lose weight (especially weight cyclers) should be assessed for binge eating severity, problematic eating behaviors, and psychological symptoms.
确定超重女性（体重指数>27.3）中与体重循环及暴饮暴食行为相关的心理特征和饮食行为。
对超重的女性体重循环者进行问卷调查，以测量自尊、自我效能感、应对策略、心理症状、抑郁、暴饮暴食、节制饮食、去抑制和饥饿感。按暴饮暴食障碍分类和暴饮暴食严重程度对受试者进行分组，比较其心理特征。
从伊利诺伊州芝加哥地区招募了62名超重的女性体重循环者作为便利样本。问卷调查在受试者家中或其他私密场所单独或分组进行。
采用学生t检验或曼-惠特尼U检验评估心理特征的差异。
36名体重循环者（58%）符合暴饮暴食障碍标准，26名（42%）不符合。有暴饮暴食障碍的体重循环者报告的暴饮暴食严重程度（P<.0005）、去抑制（P<.0005）更高，饮食自我效能感更差（P<.0005），而无暴饮暴食障碍的体重循环者则不然。有严重暴饮暴食行为的体重循环者报告的心理困扰（P<.0005）和抑郁（P<.005）更严重，自尊更低（P=.0001），且与无暴饮暴食至中度暴饮暴食问题的体重循环者相比，使用的健康应对策略更少（P=.0027）。有严重暴饮暴食行为的体重循环者还报告饥饿感更强（P<.0005），与无暴饮暴食至中度暴饮暴食问题的体重循环者相比，认知抑制更少（P=.0024）。
需要体重循环和暴饮暴食的操作定义，以促进有效减肥治疗的研究。应评估寻求减肥者（尤其是体重循环者）的暴饮暴食严重程度、问题饮食行为和心理症状。
