摘要
[目的]了解体质指数（body mass index,BMI）在婴幼儿期的变化特点,为婴幼儿肥胖的评价提供依据,探讨用BMI筛选0-3岁肥胖儿童的可行性及实用价值。 [方法]以0-3岁儿童的身高标准体重为标准筛选肥胖者,再计算各年龄组的BMI值,进行方差分析及两两比较。 [结果]BMI值随年龄变化而变化,在6-8月达高峰,,男童为18.1 kg/cm^2,女童为17.55 kg/cm^2,9月以后逐渐下降,3岁时降至最低点15.7 kg/cm^2。男女BMI随年龄变化规律基本一致,但男女童BMI值差异有显著性。 [结论]BMI随年龄变化幅度较大,0-3月以18为界值点与身高标准体重评价肥胖符合率较高,4-36月以19为界值点符合率较好。
[Objective] To study the changes in body mass index（BMI） and provide the standard measure of obesity during children aged 0～3 years. [Method] obese children were screened according to WHO reference population and the standard,the BMI of all children were calculated. [Results] BMI changed with the age,and the highest was in 6～8 months.BMI of boys was 18.1 kg/cm2 for boys,and 17.5 kg/cm2 for girls.It was lowest on 36 months of 15.7 kg/cm2.The chang of BMI by age had a same trend,but the boy＇s BMI was larger than girl＇s. [Conclusions] BMI changs greatly by ages.The cut-off point 18 is suitalble for assessment of obesity in 0～3month children,and 19 is suitalble for 4～36 months.
