目的分析中国老年居民畜禽类食物摄入状况。方法膳食调查数据来自2010—2012年中国居民营养与健康状况监测中半定量食物频率法问卷调查。采用多阶段分层与人口成比例的整群随机抽样方法进行抽样,研究对象为中国内地31个省份150个监测点65岁及以上居民,共8205名。结果我国65岁及以上老年居民每日畜禽类食物的平均摄入总量为42.0 g/d(大城市60.0 g/d,中小城市42.9 g/d,普通农村34.9 g/d,贫困农村26.4 g/d),每日畜类食物平均摄入量为33.0 g/d(大城市50.0 g/d,中小城市35.4 g/d,普通农村28.6 g/d,贫困农村19.7 g/d),每日禽类食物平均摄入量为3.3 g/d(大城市6.00 g/d,中小城市3.3 g/d,普通农村2.7 g/d,贫困农村1.8 g/d)。大城市、中小城市、普通农村、贫困农村畜禽类食物摄入总量超过我国膳食指南推荐摄入量最高50 g的人群比例分别为58.3%、44.8%、39.7%、30.1%。结论中国65岁及以上居民畜禽类食物摄入量城乡差别明显,城市摄入过量人数较多,农村摄入不足人数较多。
Objective To analyze the food intake of livestock in China’s elderly population. Methods Dietary survey data from 2010-2012 Chinese residents nutrition and health monitoring of semi-quantitative food frequency questionnaire. A multistage stratified population-based cluster random sampling method was used for sampling of 8205 residents aged 65 and over in 150 monitoring stations in 31 provinces of mainland China. Results The average daily intake of livestock and poultry in aged 65 and above residents in our country was 42.0 g / d (60.0 g / d in big cities, 42.9 g / d in middle and small cities, 34.9 g / d in rural areas and 26.4 in poor rural areas The average daily intake of livestock food was 33.0 g / d (50.0 g / d in big cities, 35.4 g / d in small and medium-sized cities, 28.6 g / d in rural areas and 19.7 g / d in poor rural areas) The average intake of poultry was 3.3 g / d (6.00 g / d in big cities, 3.3 g / d in small and medium-sized cities, 2.7 g / d in rural areas and 1.8 g / d in poor rural areas). The proportion of people who consume more livestock and poultry in large cities, small cities, ordinary rural areas and impoverished rural areas than the recommended dietary guidelines of China’s dietary guidelines is 58.3%, 44.8%, 39.7% and 30.1% respectively. Conclusions The population intake of livestock and poultry in China aged 65 and above is obviously different between urban and rural areas. There is more urban over-intake in urban areas and more in rural areas.
