2010--2012年中国成年居民食盐摄人状况

Salt intake among Chinese adults in 2010-2012

目的分析2010----2012年中国成年居民食盐摄入量状况。方法数据来自2010-2012年中国居民营养与健康状况监测，采用分层多阶段与人口成比例的整群随机抽样方法，调查对象为中国31个省份的150个县／区的18岁以上居民，共55531名。采用家庭连续3d24h食用油和调味品称重法调查家庭盐摄入量，依据家庭成员的膳食能量比计算个体食盐摄入量。采用2009年国家统计局公布的人口数据，进行复杂抽样加权处理，计算中国不同人口学特征18岁以上居民的食盐摄入量（x±sx）。结果中国成年居民平均盐摄入量为（9．6±0．3）gd，其中男性为（10．4±0．4）g／d，女性为（8．8±0．3）gd，男性高于女性；40～49、50～59、60～69岁组居民的盐摄入量分别为（9．9±0．5）、（10．3±0．4）、（9．9±0．3）gd。城市成年居民的盐摄入量为（9．0±0．50）gd，农村为（10．2±0．3）g，d，农村高于城市；大城市、中小城市、普通农村和贫困农村居民的盐消费量依次递增，分别为（7．9±0．3）、（9．2±0．6）、（9．9±0．4）和（10．8±0．7）g／d。结论中国18岁以上成年居民的盐摄入量依然处于较高水平，亟待采取措施降低食盐摄入量。

Objective To analyze the mean population intake of salt in Chinese adults in 2010- 2012. Methods Data were from the Chinese Nutrition and Health Surveillance in 2010-2012. The samples were selected through the method of probability proportion to size （PPS）. The study objects were 55 531 adults aged 18 and over from 150 sites in 31 provinces, autonomous regions or municipalities in China. The information of oil, salt and other condiments for household was from the 3 d food weighed record. The average of salt intake for individuals was calculated based on the energy percentage in one family. The results presented the level of salt intake （ x＋ sx ） by analyzing the different demography characteristics. The results were calculated using complex weighting by the population data from National Bureau of Statistics in 2009. Results The intake of salt was （9.6±0.3） g/d and it was higher in men （（10.4±0.4） g/d） than that in women （（8.8±0.3） g/d）. The intake in the age group of 40-49, 50-59 and 60-69 was （9.9±0.5） g/d, （10.3±0.4） g/d and （9.9±0.3） g/d, respectively. The adults in rural （（10.2±0.3） g/d） had a higher salt intake than that of urban （（9.0±0.5） g/d）. An average of salt intake was increased gradually in big city （（7.9±0.3） g/d）, medium /small city （（9.2±0.6） g/d）, general rural （（9.9±0.4） g/d） and poor rural （（10.8±0.7）g/d）. Conclusion The mean salt intake among Chinese adults was still in a very high level. Something should be done to reduce the salt intake for the government and policy-makers.
