Body concerns (e.g., body dissatisfaction and weight preoccupation) are well-supported prospective risk factors for the development of eating disorders in women. Body concerns are psychological variables but they are partly based on actual body mass. This study tested whether (a) body concerns predict increases in eating disorder characteristics measured both continuously (via subscale scores on the Minnesota Eating Behavior Survey (MEBS) and categorically (via transition to a probable or definite eating disorder), (b) body concerns predict changes in BMI, and (c) BMI predicts changes in eating disorder symptoms or development of an eating disorder. Beginning with 762 girls at age 11, the MEBS' Body Dissatisfaction (BD) and Weight Preoccupation (WP) scales were used to predict change in the MEBS' Bulimic Behavior scale (the sum of the Binge Eating and Compensatory Behaviors scales), in BD and WP themselves and in BMI over 18 years of follow up. Baseline BMI was also used to predict BMI and MEBS change. Contrary to expectations, BD and WP predicted significantly reduced growth in all MEBS scales and also predicted significantly reduced growth in BMI. BD, WP and BMI did not predict development of an ED. This pattern was strengthened when predictors were measured at age 17 instead of 11. We consider the possibility that the divergence between the current findings and past findings on eating disorder risk factors may stem from the unusually long developmental period studied, ranging from age 11 (or 17) through age 29. Additional longitudinal research that spans a similar developmental period could shed light on the plausibility of this explanation. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
身体担忧（例如，身体不满和体重困扰）是女性发展饮食失调的有力前瞻性风险因素。身体担忧是心理变量，但它们部分基于实际体重。本研究检验了（a）身体担忧是否预测饮食障碍特征的增加，这些特征既可以通过明尼苏达饮食行为量表（MEBS）的子量表分数连续测量（b）身体担忧是否预测 BMI 的变化，以及（c）BMI 是否预测饮食障碍症状的变化或饮食障碍的发展。从 11 岁的 762 名女孩开始，使用 MEBS 的身体不满（BD）和体重困扰（WP）量表来预测 MEBS 的暴食行为量表（暴食和补偿行为量表的总和）、BD 和 WP 本身以及 BMI 在 18 年随访中的变化。基线 BMI 也用于预测 BMI 和 MEBS 的变化。与预期相反，BD 和 WP 显著预测了所有 MEBS 量表的增长减少，也显著预测了 BMI 的增长减少。BD、WP 和 BMI 并没有预测 ED 的发展。当预测因子在 17 岁而不是 11 岁时进行测量时，这种模式得到了加强。我们考虑了这样一种可能性，即当前饮食障碍风险因素研究结果与以往研究结果的差异可能源于所研究的不寻常的长期发展阶段，从 11 岁（或 17 岁）到 29 岁。跨度相似的发展阶段的额外纵向研究可能有助于解释这种可能性。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
