湖北省部分居民1982-2002年食物消费变化趋势

目的描述湖北省城乡居民食物消费现状及变化趋势。方法在全省选取960户2942,＆进行膳食调查。膳食调查采用连续3d称重法和24h回顾询问法调查居民所有摄入食物。结果居民平均每标准人日粮谷类食物摄入量为354．2g,蔬菜为361．9g。水果为14．4g,畜禽肉类为67．6g,水产品类为53．2g,蛋类28．3g,奶类及其制品为n．3g,豆类及其制品为20．2g,食用油摄入量为51．8g,食盐为10．6g,酱油为9．4g。结论湖北省城乡居民膳食质量有所提高,其中动物性、奶类食物、水果、豆类及油脂类的摄入量均有所增加。但膳食中水果、奶类、豆类摄入量仍然很低。城乡居民膳食中谷类食物、蔬菜的消费量出现了下降趋势,但动物性食物和油脂摄入量明显上升,出现了失衡的现象。膳食结构趋向“高能量密度”,部分人群的膳食已经偏离了平衡膳食的要求。当前营养改善工作应从营养状况的双重负担的特点出发,同时解决营养不良和营养失衡的问题。
