天津市区县农村居民2002年与2008年膳食结构比较

Comparative Study of Dietary Pattern of Tianjin Rural Residents in 2008 and 2002

通过比较2008年与2002年天津市区县农村居民的膳食结构,了解天津市区县农村居民的膳食结构变迁,为提出合理膳食建议提供资料。采用整群随机抽样法抽取天津周边5个区县,391户,1 037人进行调查问卷,用3 d 24 h回顾法进行膳食调查。与2002年比较,2008年水果、豆类及制品的摄入量增加,已经达到膳食宝塔要求;蔬菜、乳类仍低于膳食宝塔推荐量;油脂摄入减少,但仍过量;蛋白质摄入增加,占RNIs的104%;VA、核黄素、抗坏血酸摄入增加,但仍低于膳食宝塔推荐量下限;钙、锌摄入增加,仍处于不足状态;铁、锌的来源动物类比例较低。天津市区县农村居民的膳食结构较2002年有了较大的改善,但膳食结构不合理,需加强对天津市区县农村居民的膳食引导。
