摘要
目的：探讨我国9地区3~12岁儿童钙及VD补充其可能的影响因素及其与膳食中钙摄入关系的分析。方法：采用多阶段整群抽样法随机选取9个地区共1 806名儿童,通过问卷调查6个月内补充剂使用情况、人口学等相关信息及半定量FFQ膳食调查;采用SPSS 13.0分析,描述不同分组下补充剂使用情况,利用因子分析提取膳食钙摄入信息,并运用卡方、多因素Logistic回归进行相关分析。结果：3~12岁儿童钙补充率为27.5%,VD补充率为16.6%,钙及VD同时补充率为13.9%。年龄越小、所在地区经济越发达、经常在家吃早餐、每天运动超过1h、父母越认为孩子瘦且饮食营养不均衡、家庭受教育程度越高等钙补充率就越高。结论：调查的3~12岁儿童的年龄、地区、在家吃早餐情况、运动情况、父母对孩子体重及饮食营养认知、家庭受教育程度是儿童钙、VD补充的显著影响因素。
