OBJECTIVE
Weight suppression (WS), maintaining a body weight below one's maximum adult weight, is associated with bingeing, purging, and weight gain in clinical samples.
METHOD
We investigated associations between eating disorder-related variables and WS and additive genetic (A), common (C), and unique (E) environmental contributions to WS in a population-based sample of 1,503 female adult twins.
RESULTS
Modeling results were similar for participants reporting no binge eating (NBE) and those reporting binge eating plus loss of control (BE + LOC): 20-25% of the variance in WS was due to A and 70-75% due to E. Among NBE participants, restraint, drive for thinness, body dissatisfaction, and dieting during child/adulthood were related to WS. Restraint, disinhibition, and dieting during childhood were significantly associated with WS in the BE + LOC subsample.
DISCUSSION
Although maintaining lower body weight could be advantageous, interventionists should take care when addressing weight suppression in individuals vulnerable to eating disorder symptomatology.
目的
体重抑制（WS）是指将体重维持在成年后最大体重以下，与临床样本中的暴食、清除和体重增加有关。
方法
我们在一个基于人群的 1503 名女性成年双胞胎样本中，调查了与饮食失调相关的变量与 WS 之间的关联，以及 WS 的加性遗传（A）、共同（C）和独特（E）环境因素的贡献。
结果
对于报告无暴食（NBE）和报告暴食加失控（BE + LOC）的参与者，模型结果相似：WS 变异的 20-25%归因于 A，70-75%归因于 E。在 NBE 参与者中，节制、对苗条的渴望、身体不满和儿童/成年期节食与 WS 有关。在 BE + LOC 亚组中，儿童期的抑制、饮食失调和节食与 WS 显著相关。
讨论
虽然保持较低的体重可能是有利的，但干预者在处理易患饮食失调症状个体的体重抑制时应谨慎。
