  1. Smoking status defined as follows: never smokers have smoked <100cigarettes/lifetime, former smokers have smoked >100cigarettes/lifetime, but do not currently smoke; current non-daily smokers report currently smoking on some, but not all days; current daily smokers report currently smoking every day
  2. aWeighted percentage indicates population percentages after application of NHANES survey weights
  3. bWeight status is defined using standard CDC-cutpoints for BMI with underweight < 18.5 kg/m2 normal weight 18.5–24.9 kg/m2 overweight 25.0–29.9 kg/m2, obese > 30 kg/m2
  4. c Income is expressed as Poverty:Income ratio, adjusted for family size
  5. d Mean BMI is calculated adjusting for age, sex, and race. Physical activity (MET-Min) is presented as standardized metabolic equivalents, assessed for 1 week
  6. Statistical significance indicated by the following designations: for *** p < 0.001, ** p < 0.01, * p < 0.05
