The variations of body fat and body composition for obese and normal adults are also investigated. This study is divided as two phases. In phase 1, 25 men and 93 women are studied. The results show that all four methods are correlated. However, no significant statistic differences presented in measurement of body fat percentile using both FFA and HHA and lower measurement (P < 0.05) observed for NIRI. Body fat percentileile is correlated with body waist circumference (WC), hip circumference (HC), waist to hip ratio (WHR), and body mass index (BMI). The significant correlated values are presented for men with WC (r=0.72, P < 0.0001) and women with BMI (r=0.79, P < 0.0001). In phase 2, the obese adults, 6 men and 21 women with BMI over 27 kg/m2 are investigated. The results demonstrate that no statistic differences presented in measurement of body fat percentile using both FFA and HHA, however, the lower measurement (P < 0.05) presented for NIRI. It also shows that the standard values are achieved using HHA for obese men (r=0.93, P < 0.05) and using FFA for obese women (r=0.80, P < 0.0001). Body fat percentile is only correlated with HC for obese men (r=0.85, P < 0.05), while it is correlated with WC, HC and BMI for obese women, the significant correlated values with BMI (r=0.78, P < 0.001). It also shows that body fat percentile is not correlated with WHR for both obese men and obese women. However, it can not show the index of weight control result.
