Weight suppression (WS), traditionally defined as the difference between highest past and current weights at adult height, is a correlate and predictor of eating disorder (ED) psychopathology. However, for growing adolescents, it may be more appropriate to use a developmentally-adjusted calculation of WS. This study compared how developmental WS, calculated using zBMIs, compared with traditional WS, calculated using weights, as correlate of ED psychopathology in treatment-seeking adolescents with transdiagnostic EDs.
Adolescents with EDs (N = 93) completed the Eating Disorder Examination Questionnaire (EDE-Q) at presentation to outpatient care. Weight histories were extracted from medical records. Regressions examined the association between each measure of WS and EDE-Q scores, adjusting for ED diagnosis. Dominance analyses with bootstrapping assessed whether developmental WS outperformed traditional WS.
Developmental WS negatively associated with EDE-Q Shape (sr = 0.05, p =.020) and Weight Concern (sr = 0.05, p =.021). In contrast, traditional WS did not associate with any EDE-Q scores. Although dominance weights were larger for developmental WS compared to traditional WS, bootstrap sampling revealed no significant differences in magnitudes.
Results preliminarily support developmental WS as a correlate of body image concerns in youth with EDs, though replication is needed.
体重抑制（WS），传统上定义为成年身高时过去最高体重与当前体重之间的差值，是饮食失调（ED）精神病理学的一个相关因素和预测指标。然而，对于正在成长的青少年，使用经过发育调整的WS计算方法可能更为合适。本研究比较了使用zBMI计算的发育性WS与使用体重计算的传统WS作为寻求治疗的跨诊断ED青少年中ED精神病理学相关因素的情况。
患有ED的青少年（N = 93）在门诊就诊时完成了饮食失调检查问卷（EDE-Q）。从病历中提取体重史。回归分析检验了每种WS测量方法与EDE-Q分数之间的关联，并对ED诊断进行了调整。采用自抽样的优势分析评估发育性WS是否优于传统WS。
发育性WS与EDE-Q体型（sr = 0.05，p = 0.020）和体重关注（sr = 0.05，p = 0.021）呈负相关。相比之下，传统WS与任何EDE-Q分数均无关联。尽管发育性WS的优势权重比传统WS大，但自抽样显示两者在大小上无显著差异。
结果初步支持发育性WS作为患有ED的青少年身体形象关注的一个相关因素，不过仍需重复验证。
