【摘要】 建立中国食物与营养监测系统是一项具有战略意义的工作.以目前卫生部在全国设立的145个疾病监测点为基础,结合国家统计局城市社会经济调查总队,农村社会经济调查总队分布在全国的600个体本县(区),依照经济发展水平分为城市、一般农村和较贫困农村3个分层,随机抽取40个个县(区)作为全国食物与营养监测点的监测方案是切实可行的,所抽取的40个监测点既是国家食物与营养监测点,作为国家疾病监测网和国家统计局的城乡住户样本的共同二级样本,可以作到三网合一资源共享,很有特点。"国家食物与营养监测系统"的40个监测点分布在26个省、自治区、直辖市,定期收集各点住户中儿童营养状况、家庭健康情况等有关方面的资料,同时通过收集相应点的上一年的抽样住户全年食物消费资料以及相应的基础卫生资料,通过综合的数据分析,得到食物营养与卫生关系的信息。本文介绍了调查的具体方案、方法和准则。为了保证1998年全国儿童营养监测现场调查数据的质量,项目技术组抽取了5个食物与营养监测点进行现场质量控制(城市2个农村3介。每个点抽取40份调查表检查质量,并对20名已测量过的3～5岁儿童再测量身高、体重,检查数据的准确性和可靠性。检查结果是表格填写完整率为96%,填写逻辑错误率为0。检查人员与调查员之间测量结果是一致的无差异。调查员两次重复测量误差无差异。数据的可靠性R均在0.95以上。说明这次调查数据是准确和可靠的。更多还原

【Abstract】 Establishment of Chinese Food and Nutrition Surveillance System is of great importance in providing information on food consumption behavior and nutrition status of the people which is essential for health,economic planning and agriculture development. Sampling of CFNSS is based on the 145 sites Disease Surveillance Point (DSP) System built by Ministry of Health,and in conjunction with the 600 sites Household Social Economic Survey System founded by State Statistics Bureau.According to indicator system developed by the Ministry of Health for stratification,strata of urban, general rural and less-developed rural were defined and 40 sites were randomly sampled as national sample.The CFNSS sample was the common sub-sample of DSP system and the SSB Household Survey System that makes sharing of information resources possible.The 40 sites are distributed in 26 Provinces/Municipalities/ Autonomous Regions.All the sites information was collected on body weight and height of children under 6 years of age,and questionnaire covering the basic family information,feeding practice and disease,health conditions of the households were surveyed by interviews. Whole year food consumption data collected at the sampled households by SSB Urban Household Survey Team and Rural Household Survey Team in the previous year was provided. Comprehensive data analysis was done to formulate the information on the relationship of food,nutrition and health.Theprotocol,methodologies and principles for the survey are described.5 sites of CFNSS were selected for quality evaluation on the anthropometric measurement and questionnaire interview.The body weight and length of 20 children of 3—5 years of age in each of 5 sites was measured again.The result showed that the completeness of questionnaires interview was 96%,the rate of logic error was zero.There was no significant difference between the results measured by supervisor and investigator and no significant error on repeated measurements.The reliability of data R =0.95.The results showed that the data was accurate and reliable.更多还原
