This study was performed to obtain an estimate of body fat and its distribution assessed by anthropometric measurements in normal (235 cases) and diabetic subjects(151cases).We assessed relative weight,body mass index (BMI),skinfold thickness,body circumference and skinfold and body circumference ratio. Also, assessment of body composition was measured by bioelectrical impedance (Valhalla 1990B). The results were as follows. 1. In normal control group,hip circumference was larger in male than female.All skinfold thickness was larger in female than male,but sexual differences were smaller than those in diabetics. 2. In diabetic subjects,hip circumference and skinfold thickness were larger in women than men. 3. In spite of the distinct changes of fat distribution observed in normal and diabetic subjects,there was no significant changes in the total body fat content. However,more body muscle mass(%) was observed in normal control than diabetic subjects. 4. In male group with normal ideal body weight,the circumferences of the arm,hip and thigh were significantly larger in control group than diabetics.But in female group,waist circumferences were larger in diabetics than control subjects. 5. The thigh and calf skinfold thickness were thicker in control subjects,but the subscapular skinfold thickness were thicker in diabetics particularly in female. 6.In female groups,waist-to-hip circumference ratio (WHR),waist-to-th igh circumference ratio(WTR) and waist-to-calf circumference ratio(WCR) were significantly larger in diabetics than control group. 7. In diabetic female patients,there were more central body fat,represented by subscapular-to-triceps skinfold ratio(STR) and central peripheral skinfold thickness ratio(CPR),than control group(female). 8. In female,there was a significant correlation between triglyceride and waist-to-hip circumference ratio(WHR),subscapular-to-triceps skinfold ratio(STR) and,in male,the abdominal skinfold thickness. 9. There was more positive correlation between the anthropometric parameters and percentage of body fat in diabetics. This study suggests that combination of various anthropometric measurements could be used as an indicator in determining the amount and effect of exercise and other remedies in diabetic patients.
