Ethnic differences in body fat distribution contribute to ethnic differences in cardiovascular morbidities and diabetes. However few data are available on differences in fat distribution in Asian children from various backgrounds. Therefore, the current study aimed to explore ethnic differences in body fat distribution among Asian children from four countries. A total of children aged y from China, Lebanon, Malaysia and Thailand were recruited using a non-random purposive sampling approach to enrol children encompassing a wide BMI range. Height, weight, waist circumference WC , fat mass FM, derived from total body water [TBW] estimation using the deuterium dilution technique and skinfold thickness SFT at biceps, triceps, subscapular, supraspinale and medial calf were collected. After controlling for height and weight, Chinese and Thai children had a significantly higher WC than their Lebanese and Malay counterparts. Asian pre-pubertal children from different origins vary in body fat distribution.

We investigated the abdominal, visceral and hepatic fat distribution in these Asian and Caucasian Americans. JA women were found to have a significantly smaller hip circumference Our findings build on limited past evidence, suggesting that Asian women carry greater abdominal and visceral fat when compared with Caucasian women with similar overall adiposity. This may contribute to their elevated metabolic risk for obesity-related diseases.
The rates of coronary disease have accelerated dramatically amongst South Asians, driven to an important extent by the atherogenic dyslipidemia and type 2 diabetes that have become so common amongst them. These precursors of vascular disease appear at lower absolute amounts of adipose tissue in South Asians than in whites. In this paper, we set out a new hypothesis—the adipose tissue overflow hypothesis—to account for these findings. The adipose tissue mass within our bodies can be divided into three different compartments: superficial subcutaneous adipose tissue, deep subcutaneous adipose tissue and visceral adipose tissue.
Ethnic differences in body fat mass and distribution may develop in childhood and contribute to increased obesity-related disease risk among Asians. We used dual-energy X-ray absorptiometry DXA to evaluate adiposity measures among adult women and their adolescent daughters, who were of predominantly Japanese and white ethnicity. We obtained DXA whole body scans for mothers aged 30 years or older and daughters aged 10 to 16 years. General linear models were used to evaluate differences in adiposity measures by ethnic category. Among mothers, gynoid fat mass and peripheral fat mass were significantly lower in Asians than in whites, whereas none of the regional DXA adiposity measures differed by ethnicity in daughters.
