Nonsmokers indicate those who reported never smoking or smoking only a few times; current smokers, those who reported smoking at least monthly but less often than once per day; daily smokers, those who reported smoking daily during the past year.
Prevalences of performing physical activity and engaging in eating behaviors according to a specified criterion are adjusted for sex, grade level (middle versus high school), race and ethnicity, and socioeconomic status. School was included in models as a random effect.
The sample size for different behaviors may vary from the total sample size because of missing responses for the variable and covariates.
Represents testing for differences in adjusted prevalences over the three categories of smoking status (2 df).
