摘要
Background: 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. %26lt;br%26gt;Methods: We obtained DXA whole body scans for 101 mothers aged 30 years or older and 112 daughters aged 10 to 16 years. The participants were classified as Asian, part-Asian, mixed/other, or white. As a measure of central adiposity, we calculated the trunk/peripheral fat ratio (TPFR). General linear models were used to evaluate differences in adiposity measures by ethnic category. %26lt;br%26gt;Results: In mothers, TPFR was significantly higher (P-trend %26lt; 0.01) in Asians and part-Asians (1.38 +/- 0.42 and 1.32 +/- 0.51) than in mixed/others and whites (1.18 +/- 0.27 and 1.09 +/- 0.21). The trend was similar among daughters (P-trend %26lt; 0.001), with respective values of 1.09 +/- 0.18, 0.97 +/- 0.17, 0.99 +/- 0.16, and 0.87 +/- 0.11. 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. %26lt;br%26gt;Conclusions: These results confirm previous reports of greater central adiposity in women of Asian ancestry and indicate that ethnic differences in adiposity are already present in adolescence.
