摘要
以上海市35岁以上城市居民15827例为研究对象,对中老年人群体质指数(BMI)的分布及理想值进行了探讨。结果显示,不同性别、年龄的死亡率曲线均可拟合Y=a─bX+cX2的二次曲线分布。将曲线最低点所对应的BMI值作为相应队列人群的理想值,并根据公式─b/2c进行计算。结果表明:不同年龄及性别组的BMI理想值均高于其相应的BMI均值,而且该理想值随年龄的增长呈上升趋势。
The distribution and the 'desirable value' of body mass index(BMI) in 15 827 middle and old-aged (over 35 years) Shanghai urban residents were studied. The results showed that the mortality curve conforms with quadratic medel(Y=a-bX+cX2) in different sex and different age groups. The desirable value of BMI corresponding to the minimal mortality in the quadratic model was calculated from the formula:b/2c. The results suggest that the desirable value of BMI is higher than the median value in different ages and sex groups and presents an upward trend with increasing age.
