Abstract

Although food insecurity might be associated with poor dietary intake, this relationship has not been researched in Korea. This study examined the association of food security with dietary intake from the third Korea National Health and Nutrition Examination Survey. Food security was measured by a self-reported hunger measure on the dietary situation of subjects' households in the previous year and approximately 2/3 of the subjects lived in food-insecure households. Dietary intake was based on a 24-hour dietary recall. Food insecurity was significantly associated with low nutrients intake and nutrients intake compared to dietary reference intakes (DRI) was also lower among subjects in food-insecure households. Overall diet quality based on dietary diversity score (DDS) was worse in food-insecure subjects. Food security should be considered an important issue to public health because dietary change due to food insecurity may affect health status.
