摘要
目的：了解绵阳市0～14岁人群维生素D（VitD）营养状况。方法调查对象为2564例在绵阳市中心医院门诊就诊的0～14岁人群，用电化学发光法测定其血清25-羟维生素D [25（O H ）D ]，对结果进行统计学分析。结果 2564例0～14岁人群25（OH）D为（30．63±12．78）ng/mL ，最低值为3．00 ng/mL ，最高值为70．00 ng/mL。VitD缺乏574例，占22．4％；VitD不足744例，占29．0％；VitD充足1246例，占48．6％。男性和女性的VitD水平差异无统计学意义（P＞0．05）。2岁以后，随着年龄的增加，VitD水平逐渐降低，VitD缺乏率逐渐升高。1～2岁为VitD水平峰值阶段。结论绵阳市0～14岁人群VitD水平较低，6岁以后VitD缺乏情况更加严重。因此，应该定期进行VitD营养状况的调查，增加孩子户外活动时间，及时补充VitD。
