  1. CI confidence interval, PAF Population Attributable Fraction
  2. Overweight: Body Mass Index (BMI) 23.00- < =24.99 kg/m2 and Obesity: BMI >25.00 kg/m2
  3. aPrevalence
  4. bOverweight and Obesity combined
  5. cOdds ratios (ORs) associating baseline body mass index and eight-year incidence of type 2 diabetes between 2005 and 2013. All ORs are adjusted for age, education, income, area of childhood residence, physical activity, smoking, alcohol intake, fruit and vegetable intake, and sugar sweetened beverage intake
  6. d PAF% calculated using the formula \( PAF\%=\frac{\sum \left( px\times \left( OR-1\right)x\right)}{1+\sum \left( px\times \left( OR-1\right)x\right)}\times 100 \)
