饮食限制与暴饮暴食症（B-ED）个体暴饮暴食风险增加的关系已经得到很好的建立。然而，以前的研究尚未确定这些人是否表现出饮食限制的异质性，以及这些特征是否与饮食病理学的差异有关。B-ED患者（N =290）完成了进食障碍检查。对饮食限制频率数据进行潜在特征分析，包括限制食物消耗总量、避免进食、空腹欲望、避免进食和饮食规则。采用三步程序，比较暴饮暴食频率、代偿行为频率和艾德病理学的已识别潜在特征。一个四类模型的饮食限制最适合的数据。各班级在补偿行为的频率上有显著差异（F（3，286）=31.01，p<.001），EDE进食问题（F（3，286）=14.36，p<.001），EDE形状相关（F（3，286）=7.06，p<.001），EDE体重关注（F（3，286）=6.83，p<.001）和艾德病理学（F（3，286）=12.86，p<0.001），但在客观（F（3，286）=2.45，p= 0.06）或主观狂欢发作（F（3，286）=1.87，p= 0.14）的频率上没有差异。B-ED患者表现出不同的饮食限制特征，这与代偿行为的频率和艾德病理的严重程度有关。
The relationship of dietary restraint in increasing risk for binge eating among individuals with binge-spectrum eating disorders (B-EDs) is well established. However, previous research has not yet identified whether these individuals exhibit heterogeneous profiles of dietary restraint and whether these profiles are associated with differences in eating pathology. Individuals with B-EDs (N =290) completed the Eating Disorder Examination. Latent profile analysis was conducted on dietary restraint frequency data, including restriction of overall amount of food consumed, avoidance of eating, desire for an empty stomach, food avoidance, and dietary rules. Identified latent profiles were compared on binge eating frequency, compensatory behaviors frequency, and ED pathology using the three-step procedure. A four-class model of dietary restraint best fit the data. Classes significantly differed in frequency of compensatory behaviors (F(3, 286)=31.01, p<.001), EDE eating concern (F(3, 286)=14.36, p<.001), EDE shape concern (F(3, 286)=7.06, p<.001), EDE weight concern (F(3, 286)=6.83, p<.001) and ED pathology (F(3, 286)=12.86, p<.001), but did not differ in frequency of objective (F(3, 286)=2.45, p=.06) or subjective binge episodes (F(3, 286)=1.87, p=.14). Individuals with B-EDs exhibit distinct profiles of dietary restraint, which are associated with frequency of compensatory behaviors and severity of ED pathology.
