目的评价营养素钙片制剂干预对海南省黎族少年学生体格发育的效果。方法选择生长发育突增期的黎族学生分为两组,一组107名为干预组进行营养素钙片制剂干预,另一组111名为对照组,通过人体测量判断干预组生长发育指标的变化,采用t检验比较干预组和对照组少年学生生长发育差异同时与2005年全国汉族少年学生生长发育水平进行比较,评价干预效果。结果干预组与对照组均值身高比较,男女均有显著性差异(P<0.01);两组学生的体重比较,女性学生有显著性差异(P<0.01),男性差异不大(P>0.05);干预组与全国汉族同年龄学生身高相比,干预组男生均值高于全国汉族学生水平,差异有统计学意义(P<0.01),干预组女生均值与全国汉族女生水平差异无显著性(P>0.05)。结论通过给生长发育突增期的黎族地区少年学生补充营养素碳酸钙D3制剂,可以显著提高黎族地区少年学生生长发育水平。
Objective To evaluate the effect of nutrient calcium preparations on the physical development of Li minority adolescents in Hainan Province. Methods A total of 107 Li nationality students with sudden onset of growth and development were divided into two groups. 107 patients in the intervention group were treated with nutrient calcium tablets and 111 in the control group. The changes of growth and development indexes in the intervention group were judged by human body measurements. The t-test was used to compare the growth and development differences between the intervention group and the control group and the growth and development level of the Han nationality teenagers in 2005, so as to evaluate the intervention effect. Results There was a significant difference between the mean height of the intervention group and the control group (P <0.01). There was a significant difference between the two groups in female students (P <0.01) and in male (P> 0.05) (P <0.01). There was no significant difference between the intervention group and the national female students in the Han nationality (P <0.01), while the average level of male students in the intervention group was significantly higher than that of the Han nationality (P <0.01) > 0.05). Conclusion Supplementing nutrient D3 supplementation to juvenile students in the Li ethnic minority areas during the sudden growth period can significantly improve the growth and development of juvenile students in the Li ethnic region.
