宁波市象山县婴儿肥胖检出率及喂养状况调查

目的调查宁波市象山县婴儿肥胖检出率及喂养状况。方法对本地区478名12月龄婴儿进行体格检查和问卷调查,分析肥胖情况和喂养方式。结果肥胖率为9.83%。出生后至12月龄单纯母乳喂养构成比逐渐下降,混合喂养和单纯人工喂养的构成比逐渐上升,9个月后混合喂养构成比下降,人工喂养构成比最高。母乳喂养时间越长婴儿肥胖率越低,而在4～6个月添加辅食的婴儿肥胖率较低。单纯母乳喂养组超重及肥胖检出率均最低。不同母乳喂养持续时间、添加辅食时间的婴儿肥胖率差异有统计学意义(P<0.05),母乳喂养及母乳喂养时间长对婴儿肥胖有保护作用。结论早期添加配方奶粉及辅食喂养导致婴儿早期肥胖可能性增加,母乳喂养及母乳喂养时间长可降低婴儿的肥胖率。
