To improve the usefulness of the Korea National Health and Nutrition Examination Survey (KNHANES) and address emerging health issues, we propose a framework for a rotating survey for the KNHANES, aiming to satisfy the diversification of survey domains or items and minimize the response burden on survey participants simultaneously. To establish a rotating survey system for the health survey of the KNHANES, the research was conducted in the following 5 steps: 1) review and analysis of health survey for the 5th to 9 th KNHANES, 2) first consultation with experts in each domain of health topics, 3) drafting a framework for the rotating system of the KNHANES, 4) second expert consultation, and 5) proposal of the final draft. Core items in all domains are surveyed annually. In the health behaviors domain, after classifying all topics into 5 groups in consideration of the interrelationships between topics, the 6-year survey cycle ( rotating items) was established by assigning the survey cycle differently to 2 years (2 groups) or 3 years (3 groups). The annual average numbers of survey items for 6 years is 197 items (fixed items 179, rotating items 18). Health literacy, digital health, and infectious disease have been proposed as emerging new health issues to be included in the KNHANES. By implementing a rotating survey system, it is expected to reduce the response burden of the survey participants, to increase the efficiency of the survey, and to produce timely health statistics.
