Comparison of morbidity of obesity by bioelectric impedance analysis,BMI,waist circumference in young healthy people

Objective: To compare morbidity of obesity by different measurements in young healthy people.Methods: The height,weight,waist circumference（WC）,hip circumference（HC）,mid-upper arm circumference（MAC）,triceps skinfold thickness（TSF）,subscapular skinfold thickness（SSF） in 369 young people with average of（27.1±9.4）years were measured.In addition,BCA-2A Body Analysis Instrument was applied to measure body compositions.Five indices to estimate and compare fat rate for men and women were used,including the percent of body fat（F%）,body mass index（BMI）,WC,ideal body weight and TSF+SSF.Results: There was significant difference in the overall parameters of men and women（P＜0.05）.There were also significant differences between rates of fat by five indices for men and women.The highest rate of screening of obesity was the percent of body fat（F%）,the lowest was ideal body weight.Conclusion: Bioelectric impedance analysis（BIA） is a more sensitive way for screening of obesity.
