Non-dieters as reference class. Reference latent class has odds of ratio 1.0. Predictors entered in separate logit models. *P < 0.10, **P < 0.05, ***P < 0.01,
P < .0001
Body fat percentage was measured using Dual-energy X-Ray absorptiometry (DXA).
Measured using the restraint subscale from the DEBQ
Measured using the disinhibition subscale from the DEBQ)
Measured using the Weight Concerns Scale
Measured using the Dieting subscale on the EAT
Measured using the Rosenberg Self-Esteem Scale
Measured using the CES-D
Measured using the Binge Eating Scale
Dieting frequency is self-reported, measured as the frequency of dieting during the past year.
