Why is it important?
Average BMI of residents is essential information to plan, implement, and evaluate national and local public health programs to improve their lifestyles and prevent obesity.
Perspectives
Although mean BMI is generally lower in Japan than in other countries, there is a substantial difference in BMI levels across prefectures. Particularly mean BMI in southwest prefectures has been rising more rapidly than in other prefectures. Motorization as well as westernization of diets might be a contributor to the trends and distributions of prefectural BMI.
