海南黎族少年学生营养素钙制剂干预效果评价

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。
