National obesity risk *5/10This is a composite ‘obesity risk’ score (out of 10, the highest risk) based on obesity prevalence, rate of increase, likelihood of meeting the 2025 target, treatment indicator and childhood stunting levels.Childhood obesity risk *3/11This is a ‘risk score’ for each country’s likelihood of having or acquiring a major childhood obesity problem during the 2020s, taking account of current prevalence levels and risk for future obesity (based on stunting among infants, maternal obesity, maternal smoking, and breastfeeding rates).

| Definitions: | The Japanese Society for the Study of Obesity cutoffs define BMI ≥ 25 as obesity. However, as this study reports BMI using standard cutoffs (Overweight: BMI =>25-29.9 & Obesity: => 30) this is shown here to allow for comparison with non-Asian WHO cutoffs. Data using the Japanese Society for the Study of Obesity cutoffs are shown below. |

| Notes: | *Since the surveys in 2012 and 2016 were conducted with a larger number of subjects than the regular surveys, weighting was applied to correct the difference in the number of households in each prefecture between the regular survey year and the 2012 and 2016 surveys in order to compare the results with the regular survey year, and the results were calculated as nationally adjusted values. |
