目的评价广西居民膳食模式,为制订膳食模式改善策略提供科学依据。方法用多阶整群随机抽样法抽取4城区、4农村县,4268户、17104人。用称重法获调味品量,3d24h回顾法获个人食物量,用中国居民平衡膳食宝塔评价广西居民膳食模式。结果广西居民谷类、蔬菜、水果、鱼虾、蛋类、奶类、豆类摄入不足,盐、畜禽肉、油脂摄入过量。畜禽肉、鱼虾、奶类、蔬菜、水果、蛋类、油脂摄入量是省会城市>一般城市>二类农村>四类农村,表现出与经济发展水平呈正比关系。畜禽肉、鱼虾、奶类、蛋类、水果摄入量是高收入组>中收入组>低收入组,表现出与经济收入呈正比关系。蛋、奶、豆类、水果摄入逐年递增和食盐摄入逐年下降,向合理膳食模式靠近。畜禽肉、油脂摄入逐年递增和谷类、蔬菜、鱼虾摄入逐年下降,背离合理膳食模式要求。城市摄入动物性食品总量有放缓趋势,而农村有加速趋势,与经济水平发展进程有关。广西居民营养有明显的由低脂膳食向高脂膳食转变趋势。结论广西已进入居民膳食模式的迅速变迁期,已到了膳食模式干预的关键阶段。
