Relationship among BMI,waist circumference and anthropometric measurements

Objective: To investigate the relationship between body mass index（BMI）,waist circumference（WC） and body fat distribution.Methods: Anthropometric measurements,percentage of body fat were measured by bioelectrical impedance analysis（BIA） in 449 men（mean age 38.74±16.5 years） and 569 women（mean age 40.23±15.6 years）of healthy adults aged 18-74 years.Subjects were divided by BMI 18.5-23.9 for normal weight,BMI 24-27.9 for overweight,BMI ＞28 for obesity,and by WC ≤85cm in men and ≤80cm in women for health,WC ＞85cm in men and ＞80cm in women for abdominal adiposity.Results: The anthropometric results were progressively and significantly higher with increasing of BMI in both men and women.The mean age was 44 and 45 years in overweight and obesity respectively in men,significantly younger than in women.waist-to-height ratio was more correlated than BMI,WHR,and CI.Conclusion: Subjects at age of 45 have a highter risk to develop obesity in men.Waist circumference in the normal weight individuals should not be more than half of their heights.
