Objectives: To obtain scientific basic data to be used for future countermeasures against diabetes by clarifying the current state of diabetes and related physical conditions in Tochigi Prefecture.Methods: Based on the results from health and nutrition survey on residents of Tochigi prefecture in 2009, those surveyed were categorized into the following three groups: those strongly suspected of having diabetes (group A), those with the undeniable possibility of having diabetes (group B), and those having no diabetes. And, the following analyses were performed on those groups: 1) Analyzing factors associated with diabetes, 2) Estimating prevalence rate of diabetes, 3) Considering regional characteristics and trend over the years, 4) Estimating future prevalence rate and number of diabetes.Results: 1) Obesity and related factors (e.g., abdominal circumference and BMI) were significantly related to the risk of diabetes. 2) Prevalence rate of diabetes was higher in group A and lower in group A + B than their corresponding national averages. 3) BMI, weight, and total energy intake in male were higher than those of national averages. BMI was significantly increased in male and decreased in female as compared to the survey results in 2003. 4) Due to the increase in BMI levels, future prevalence rate and number of diabetes were projected to increase larger than those expected from aging alone. Also, the prevalence was expected to be improved by achieving the target of body weight.Conclusions: Obesity was the key risk factor for diabetes in Tochigi prefecture. Also, a strong increasing trend of obesity in Tochigi prefecture was confirmed. The future prevalence of diabetes was expected to be improved by reducing the BMI increase.
