Values are expressed as frequency for categorical variables and x̄ ± SD for continuous variables.
2
Chi-square tests for categorical variables and t tests for continuous variables were used to compare children with and without reported binge eating-episodes. Socioeconomic status was determined based on parents’ education and employment history.
3
BMI z score is a SD score for children’s BMI accounting for age and sex, calculated according to a formula from the Centers for Disease Control and Prevention (1).
