Abstract
The relationship between body mass index (BMI) and percentage standard weight (PSW) was investigated in 50 male and 50 female Japanese patients with NIDDM in the Sanin. district. BMI was found to correlate highly with PSW. From the equation relating PSW and BMI, it could be calculated that BMI, at 120% PSW, was 25.39 in males and 25.49 in females. It appears that patients whose BMI is equal to or greater than 25 should be regarded as obese in Japanese NIDDM.
