Abbreviations: AOR, adjusted odds ratio; CI, confidence interval.

^a Numbers may not add to total because of missing values. All analyses controlled for age, grade level, and school location.

^b Odds ratios adjusted for age, grade level, father's physical activity level, mother's physical activity level, close friends' physical activity level, smoking status, school location, clustering by school, and all other variables in the table.

^c Students who were less than the 5th percentile for BMI by sex were classified as underweight, students who were in the 85th percentile or higher for BMI by sex were classified as at risk of overweight/overweight, and students who were in the 5th to less than the 85th percentile for BMI by sex were classified as normal weight.

^d P < .05.

^e P < .01.

^f P < .001.
