  1. Abbreviations: BMI, body mass index; MDCS, Malmö Diet and Cancer Study; WHR, waist-to-hip ratio.
  2. Data are number of participants (%) or mean (s.d.). BMI for age 20 was calculated by using self-reported weight at 20 years and height at baseline.
  3. aNormal weight=BMI<25 kg m−2.
  4. bOverweight=25⩽BMI<30 kg m−2.
  5. cObese=BMI⩾30 kg m−2.
