Outline of Final Research Achievements

In order to clarify the relationship between body weight and medical expenses in Japan, this study focused on data on specific health checkups and specific health guidance (NDB) and data on national medical expenses, and examined per capita medical expenses and BMI25. We compared and analyzed the proportion of people with weight above 20 years old and the proportion of people who gained 10 kg or more from their 20-year-old weight in each prefecture.
As a result, there was no correlation between medical expenses per person and the proportion of people with a BMI of 25 or higher (R = -0.013, p = 0.930). There was also no correlation between per capita medical expenditure and the proportion of people who gained 10 kg or more from their 20-year-old weight (R = 0.086, p = 0.564).

Academic Significance and Societal Importance of the Research Achievements

本研究の結果では、各都道府県の国民一人当たりの医療費とBMI25以上の人の割合や、20歳の時の体重から10kg以上増加している人の割合には、相関がみられなかった。国民一人当たりの医療費とBMI25以上の人の割合や、20歳の時の体重から10kg以上増加している人の割合の間に地域ごとの相関が無かったという結果は、医療政策分野の学術的意義や社会的・医療経済的意義がある。さらに、今後これらの研究結果から発展して研究を行うための有用な基礎資料となりうる。
