the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2016

The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). This nationally representative cross-sectional survey includes approximately 10 000 individuals each year as a survey sample and collects information on socioeconomic status, health-related behaviours, quality of life, healthcare utilization, anthropometric measures, biochemical and clinical profiles for non-communicable diseases and dietary intakes with three component surveys: health interview, health examination and nutrition survey. The health interview and health examination are conducted by trained staff members, including physicians, medical technicians and health interviewers, at a mobile examination centre, and dieticians’ visits to the homes of the study participants are followed up. KNHANES provides statistics for health-related policies in Korea, which also serve as the research infrastructure for studies on risk factors and diseases by supporting over 500 publications. KCDC has also supported researchers in Korea by providing annual workshops for data users. KCDC has published the Korea Health Statistics each year, and microdata are publicly available through the KNHANES website (http://knhanes.cdc.go.kr).

韩国国家健康与营养检查调查（Korea National Health and Nutrition Examination Survey, KNHANES）是自1998年起持续评估韩国国民健康与营养状况的全国性监测体系。依据《国民健康促进法》，该调查由韩国疾病控制与预防中心（Korea Centers for Disease Control and Prevention, KCDC）牵头实施。这项具有全国代表性的横断面调查每年抽取约10000名个体作为调研样本，通过健康访谈、健康检查与营养调查三大组成模块，收集社会经济地位、健康相关行为、生活质量、医疗服务利用情况、人体测量指标、非传染性疾病的生化与临床特征以及膳食摄入等多维度信息。健康访谈与健康检查均在流动检查中心由经过专业培训的人员开展，涵盖医师、医技人员与健康访谈员；同时营养师会上门跟进调研参与者的相关情况。KNHANES可为韩国健康相关政策制定提供数据支撑，同时凭借每年支持发表超500篇学术论文，成为危险因素与疾病相关研究的核心研究基础设施。此外，韩国疾病控制与预防中心还通过为数据使用者举办年度研讨会，为韩国国内研究者提供支持。该中心每年发布《韩国健康统计年鉴》，微观数据可通过KNHANES官方网站（http://knhanes.cdc.go.kr）公开获取。
