Abbreviations: BMI, body mass index; NA, not applicable.
a
Analyses adjusted for baseline perceived weight status, sex, race/ethnicity, grade, school district, school-level percentage of students eligible for free and reduced-price meal, and calendar year. For all outcomes except weight satisfaction, higher scores reflect poorer outcomes (increased teasing, talk, or concerning weight control behaviors).
b
P value for between-group difference.
c
Between-group difference: BMI reporting group and BMI screening group combined minus control group.
d
Between-group difference: BMI reporting group minus BMI screening group and control group combined.
