目的了解宁波市区0岁~12岁儿童25羟维生素D[25(OH)D]、维生素A(VitA)、维生素E(VitE)营养状况及其影响因素。方法对2020年10月—2022年10月在本院及本院医共体卫生院儿童保健科就诊的3024例0岁~12岁儿童的25(OH)D、VitA、VitE数值进行统计分析,分析季节、年龄、性别等影响因素。结果0岁~10岁男童、女童25(OH)D水平均逐年下降。8岁~12岁男童、女童25(OH)D水平差异无统计学意义。男童25(OH)D水平均高于同年龄段女童,但男女比较差异无统计学意义。0岁~10岁儿童25(OH)D充足率逐年下降。儿童在7岁后夏秋季节25(OH)D水平高于冬春季节,7岁前没有明显季节规律。儿童VitA不足率为0.5%,VitA水平在1岁以内最高。儿童VitE不足率为0.2%,VitE水平2岁之前最高,VitE水平秋季高于其他季节。结论宁波市区0岁~10岁儿童25(OH)D水平及充足率逐年下降,同年龄有关。8岁~12岁儿童25-(OH)D水平无明显差异。男童25(OH)D水平均高于同年龄段女童。儿童7岁之前25(OH)D水平无季节规律,7岁后有季节规律。0岁~12岁儿童VitA、VitE基本不缺乏。
