^aAll models adjusted for age, race/ethnicity, biological sex, household income, parental education, body mass index, and baseline sleep disturbances.

^bRestrictive eating behaviors include fasting or skipping meals

^cCompensatory behaviors include vomiting, laxatives, diuretics, or weight loss pills for weight loss
