Body fat percentage in females, inhabitants were significantly greater than for males, BMI increased with are in males and females, and BMI in males was significantly more than in females from 20 and 50 years of age. A definite correlation was obtained between body fat percentage and BMI in males and females. A ratio of obesity based on body fat percentage, and BMI in males was significantly more than for females, and that of obesity in middle age or the elderly were more than for younger persons.
