目的了解北京市丰台区居民食物消费的总体情况。方法采用多阶段分层整群随机抽样的方法,2010年8-10月在丰台区抽取6个居委会180户居民共计595人进行膳食调查,计算每标准人日食物消费量。膳食调查采用24h膳食回顾法与调味品称重法相结合的方法。结果丰台区居民每标准人日谷类、薯类、豆及豆制品、蔬菜、水果、坚果、畜禽肉类、奶及奶制品、蛋及蛋制品、水产类、食用油、糖及淀粉、糕点小吃类、盐、酱油的摄入量分别为337.1、27.2、11.0、258.6、119.8、3.9、77.0、71.4、41.8、20.2、36.7、7.1、13.1、9.3和13.5g。城镇居民蔬菜、水果、禽畜肉、蛋及蛋制品、水产品的摄入量与人均收入水平成正相关,相关系数分别为0.151、0.234、0.123、0.142和0.142;薯类、盐的摄入量与人均收入水平成负相关,相关系数分别为-0.134和-0.108。结论与2002年北京市居民膳食结构相比,丰台区居民膳食结构有所优化,但仍存在不利于健康的因素。
