中国乡村汉族脂肪质量指数与瘦体质量指数的地理性分布

Geographical distributions of fat and lean mass indices in rural Chinese Han

2009-2013年测量了中国36个汉族乡村族群的体质数据值,计算了脂肪质量指数和瘦体质量指数,进行了乡村汉族人的脂肪质量指数、瘦体质量指数与纬度的相关分析。研究结果表明:男性瘦体质量指数与纬度呈正相关(P<0.01),而脂肪质量指数与纬度无相关(P>0.05)。女性的脂肪质量指数、瘦体质量指数与纬度均呈正相关(P<0.01)。从南方到北方,男性瘦体质量指数呈线性增长是导致男性体质量指数与纬度相关的原因。女性瘦体质量指数、脂肪质量指数均呈线性增长,共同导致女性体质量指数与纬度的相关。

Physical characteristic values of rural Chinese Han living in 36 areas around China were measured from 2009 to 2013. Fat mass index （Ifm） and lean mass index （Ilm） were calculated and the correlation between these indices and latitude determined. The results showed that male Ilm was positively correlation with latitude, but there were no correlation between Ifm and latitude （P〉0.05）. In females, there were positive correlations between Ifm, Ilm and latitude, respectively （P〈0.0l）. Male Ilm values were linear increasing from south to north, which explains why Im correlated with latitude. Both female Ilm and Ifm increased linearly thus showing a correlation between Im and latitude.
