  1. Date were weighted or corrected for self-report bias.
  2. Overweight is defined as a BMI ≥ 25 and <30 kg/m2. Obesity is defined as a BMI ≥ 30 kg/m2. Results are expressed as percentage, obtained using original sample data weighted to reflect the Swiss population (uncorrected, weighted), BMI corrected for reporting bias (corrected, unweighted) and BMI corrected for reporting bias and weighted to reflect the Swiss population (corrected, weighted). a gender-specific correction; b, gender and age-specific correction.
