While BMI was included as a covariate, data are shown here as BMI percentiles to aid in interpretation.

2

Body fat percentage was measured using Dual-energy X-Ray absorptiometry (DXA).

3

Measured using the restraint subscale from the DEBQ; range 1(low) to 5(high)

4

Measured using the disinhibition subscale from the DEBQ; range 1(low) to 5(high)

5

Measured using the Weight Concerns Scale; range 0(low) to 5(high)

6

Measured using the Dieting subscale on the EAT; range 0(low) to 27(high)

7

Measured using the Rosenberg Self-Esteem Scale; range 10(low) to 40 (high)

8

Measured using the CES-D; range 0 (low) to 60 (high)

9

Measured using the Binge Eating Scale; range 0(low) to 46 (high)

10

Dieting frequency is self-reported, measured as the frequency of dieting from never (1) to everyday (5) during the past year.
