[Cause and control of non-sampling error in China National Human Biomonitoring Program].

The size of the non-sampling error is directly related to the accuracy and reliability of the sampling survey result. This paper studied the non-sampling errors generated during the sampling process of the China National Human Biomonitoring Program(CNBP), mainly including the sampling frame error, non-response error and measurement error. The program reduced the influence of the non-sampling error on the quality of the survey effectively by scientifically designing the sampling scheme and questionnaire, strengthening investigator trainings and standardizing the data review, which could be used to provide reference for the control of non-sampling errors in public health monitoring projects in China.非抽样误差的大小直接关系到抽样调查结果的精度和可靠性。本文研究了国家人体生物监测项目抽样过程中产生的非抽样误差，主要有抽样框误差、无应答误差及计量误差。项目针对出现的非抽样误差及时深入分析原因并调整方案，通过科学设计抽样方案、合理设计调查问卷、加强调查员培训及规范数据审核等措施进行预防和控制，有效降低非抽样误差对调查质量的影响，为我国其他大型公共卫生监测项目中非抽样误差的控制提供参考。.
