Subtyping Disordered Eating in a Community Sample of Girls

About the Course:

Objective: 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. Method: 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. Results: 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. Compared to 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. Conclusion: Dietary restraint and depressive symptoms combined predict binge-eating longitudinally in a diverse community sample of girls.
