  2. a Model adjusted for baseline age and race-ethnicity using Cox proportional hazards models.
  3. b Model adjusted for baseline age, race-ethnicity, smoking status, respondent-assessed health status, and preexisting health conditions (history of heart disease, stroke hypertension, diabetes, cancer, chronic bronchitis, or emphysema) using Cox proportional hazards models.
  4. cP<0.05.
  5. Weight loss is self-reported maximum weight minus measured weight at baseline as a percentage of maximum weight. Healthy weight is BMI of 18.5–24.9. Overweight is maximum BMI of 25.0–29.9. Obese is maximum BMI of 30.0 or higher.
