Respondents are categorized as follows:
  • No/None: did not report behavior at Time 1 or Time 2
  • Starter: reported behavior at Time 2 but not at Time 2
  • Stopper: reported behavior at Time 1 but not at Time 2
  • Persistent user: reported behavior at Time 1 and Time 2

Adjusted for ethnicity/race, SES, age cohort, and Time 1 BMI

p-values are for comparisons with no dieting or unhealthy WCB for adjusted 10-year increases in BMI
