Development of Food Security Measures for Korean National Health and Nutrition Examination Survey

Abstract

Given that household food security issues have become the concern of the Korean society, this study aimed to develop food security measures for the Korean population. Based on the literature reviews on previously developed food security measures, the 18-item US household food security survey module (US HFSSM) was adapted. The developed food security measures was assessed by qualitative validity method. It was evaluated and modified by face validity by expert focus groups belong to university, public health center, and government agencies and by cognitive interview by 40 subjects with low household income who live in an urban community and are participants in welfare programs of local districts. Then, it was reviewed and revised by the National Institute of the Korean Language and the advisory committee for nutrition survey of Korean National Health and Nutrition Examination Survey (KNHANES). The results showed that the developed questionnaire items were well adapted by expert focus groups and general subjects, showing the feasibility of measuring food security with the developed measures although there were discrepancies in some expressions of questionnaire items between experts focus groups and general subjects. The study to assess reliability and quantitative validity of the developed food security measures should be further needed to examine its application for KNHANES.
