This study tests the validity of the "dietary-depressive" subtype (typified by greater negative affect) and a "dietary" subtype (typified by dietary restraint only) using a diverse longitudinal community sample.
Girls at ages 10, 12, and 14 completed the Child Eating Attitudes Test, the Child Symptom Inventory-4, and Body Image Measure. Body Mass Index was assessed at each age.
Unlike previous studies, cluster analysis revealed an at-risk "dietary-depressive" (R+) subtype (18.7%,100/534) and a not at-risk (R-) subtype, distinguished by few depressive symptoms and little dietary restraint (81.3%,434/534), but no "dietary" subtype. When compared with the R- subtype, the R+ subtype had significantly greater eating disordered behavior and attitudes. The R+ subtype at age 10 was a risk factor for binge-eating but not obesity at ages 12 and 14.
Dietary restraint and depressive symptoms combined predict binge-eating longitudinally in a diverse community sample of girls.
本研究使用一个多样化的纵向社区样本，检验“饮食-抑郁”亚型（以更强的消极情绪为特征）和“饮食”亚型（仅以饮食限制为特征）的有效性。
10岁、12岁和14岁的女孩完成了儿童饮食态度测试、儿童症状量表-4和身体意象测量。在每个年龄段评估体重指数。
与之前的研究不同，聚类分析揭示了一个有风险的“饮食-抑郁”（R+）亚型（18.7%，100/534）和一个无风险（R-）亚型，其特征是抑郁症状少且饮食限制少（81.3%，434/534），但没有“饮食”亚型。与R-亚型相比，R+亚型有明显更多的饮食失调行为和态度。10岁时的R+亚型是12岁和14岁时暴饮暴食的风险因素，但不是肥胖的风险因素。
在一个多样化的社区女孩样本中，饮食限制和抑郁症状相结合可纵向预测暴饮暴食。
