摘要： 目的 通过横断面研究,了解上海市3~6岁儿童隔代养育情况及其饮食运动习惯差异。方法 在上海市18个市辖区各抽取2所幼儿园,通过问卷调查形式收集儿童家庭情况、体格发育、营养膳食和体育活动信息。结果 样本共纳入儿童1 637名,其中隔代养育的比例为30.5%。不同养育方式下儿童的超重及营养不良的发生率差异无统计学意义(χ²=0.001,P=0.982)。不同养育方式下的幼儿都存在就餐时间过长、日饮水量不足及园外活动时间缺乏的问题。其中隔代家长在饮食及运动的选择上更加多样化。结论 上海市3~6岁儿童中亲代养育的比重更大,不同养育方式下儿童的饮食运动习惯存在差异。就餐时间过长、日饮水量不足及园外活动时间缺乏是两类养育方式下幼儿的共同问题。在运动方式和运动场地的选择上体现出上海市儿童生活环境变化特点。
