目的:分析广西城乡居民食物消费状况,了解居民膳食结构变化趋势。方法:利用1989、1991、1993、1997、2000、2004、2006、2009年“中国健康与营养调查”项目8次追踪调查资料,选取18—60岁居民作为调查对象,采取连续3d 24h膳食回顾法,获得居民每人每天食物消费量。结果:1989—2009年广西18—60岁居民谷类、豆类摄入量呈逐年下降趋势,尤其是谷类食物由1989年的483.5±116.3g/d,下降到2009年的389.0±133.0g/d,下降幅度为19.5%;蔬菜类食物的摄入量变化不大,基本维持在335.8—348.6g/d;水果、奶类、鱼虾类、蛋类食物摄入量和消费率虽然逐年均有所增加,但摄入量和消费率严重偏低;而禽畜肉摄入量却呈逐年上升趋势,由1989年的89.2±78.7g/d,上升至2009年的159.6±87.9g/d,上升幅度为78.9%;食用油、盐摄入量也偏高,至2009年分别达到38.8g/d和7.7g/d,超过推荐量标准。结论:21年间广西居民的膳食结构模式已从植物性膳食向动物性膳食转变,应引起高度关注。
