Several studies have shown a race difference in the association between BMI and percentage of body fat. For a given BMI, Chinese, Malay, Indian, Taiwanese, and Indonesian men and women have a higher percentage of body fat compared with Caucasians.10-14 Differences in trunk-to-leg-length ratio, slenderness, and muscularity may contribute to these racial differences in the percentage of body fat-BMI relationship.80,81 No clear differences in the relation between percentage of body fat and BMI have been observed for African-Americans vs Caucasians.67 Based on these findings and the observed differences in the relation between BMI and disease risk, lower BMI cut-points have been suggested to define overweight and obesity for specific ethnic groups.10-12,82-84 However, the expert committee of the WHO has not redefined the cut-points for specific Asian populations, because available data do not necessarily indicate a clear BMI cut-off point for all Asian ethnic groups.85
Ethnic differences in the relation between waist circumference and visceral fat have frequently been reported. Asian ethnic groups generally have a smaller waist circumference compared with Caucasians, although this is not necessarily true for Asian emigrants who are generally affluent and have more generalized and abdominal obesity.38,86 Despite the smaller waist circumference, the visceral fat mass is higher for Asians compared with Caucasians and African-Americans.87,88 Moreover, for specific Asian groups disease risks may already be increased at a lower level of waist circumference, suggesting that a lowering of the waist circumference cut-points should be considered for these ethnic groups.38,82,83 For a similar waist circumference (or WHR) and BMI, African-Americans have a lower visceral fat mass compared with Caucasians.89-91 Although a larger amount of visceral fat is associated with a higher disease risk in both African-Americans and Caucasians, similar amounts of visceral fat are associated with different levels of metabolic risk factors in these groups.92 The cause of the more diabetogenic profile in African-Americans as compared with Caucasians is currently unknown.93
another studie shows Dutch caucasian people have the highest fat free bodymnass. after the caucasian dutch the norwegians and swedes and the peoples of the Dinaric Alps.
