To characterize patterns of weight-related self-monitoring (WRSM) among US undergraduate and graduate students and examine associations between identified patterns of WRSM and eating disorder symptomology.
Undergraduate and graduate students from 12 US colleges and universities (N = 10,010) reported the frequency with which they use WRSM, including self-weighing and dietary self-monitoring. Eating disorder symptomology was assessed using the Eating Disorder Examination Questionnaire. Gender-specific patterns of WRSM were identified using latent class analysis, and logistic regressions were used to identify differences in the odds of eating disorder symptomology across patterns of WRSM.
Among this sample, 32.7% weighed themselves regularly; 44.1% reported knowing the nutrition facts of the foods they ate; 33.6% reported knowing the caloric content of the foods they ate; and 12.8% counted the calories they ate. Among women, four patterns of WRSM were identified: "no WRSM," "all forms of WRSM," "knowing nutrition/calorie facts," and "self-weigh only." Compared with the "no WRSM" pattern, women in all other patterns experienced increased eating disorder symptomology. Among men, three patterns were identified: "no WRSM," "all forms of WRSM," and "knowing nutrition/calorie facts." Only men in the "all forms WRSM" pattern had increased eating disorder symptomatology compared with those in the "no WRSM" pattern.
In a large sample of undergraduate and graduate students, engaging in any WRSM was associated with increased eating disorder symptomology among women, particularly for those who engaged in all forms. Among men, engaging in all forms of WRSM was the only pattern associated with higher eating disorder symptomology.
描述美国大学生和研究生体重相关自我监测（WRSM）的模式，并探讨识别出的 WRSM 模式与饮食障碍症状之间的关联。
来自美国 12 所高校的本科生和研究生（N=10010）报告了他们使用 WRSM 的频率，包括自我称重和饮食自我监测。使用饮食障碍检查问卷评估饮食障碍症状。使用潜在类别分析确定 WRSM 的性别特异性模式，并使用逻辑回归确定 WRSM 模式之间饮食障碍症状的可能性差异。
在该样本中，32.7%的人定期称重；44.1%的人报告知道他们所吃食物的营养成分；33.6%的人报告知道他们所吃食物的卡路里含量；12.8%的人计算他们所吃的卡路里。在女性中，确定了四种 WRSM 模式：“不进行 WRSM”、“所有形式的 WRSM”、“了解营养/卡路里事实”和“仅自我称重”。与“不进行 WRSM”模式相比，所有其他模式的女性都经历了更多的饮食障碍症状。在男性中，确定了三种 WRSM 模式：“不进行 WRSM”、“所有形式的 WRSM”和“了解营养/卡路里事实”。与“不进行 WRSM”模式相比，只有“所有形式 WRSM”模式的男性饮食障碍症状更多。
在一个大型的大学生和研究生样本中，进行任何形式的 WRSM 都与女性饮食障碍症状的增加有关，尤其是那些进行所有形式的 WRSM 的女性。在男性中，进行所有形式的 WRSM 是唯一与更高饮食障碍症状相关的模式。
