Analysis of the Difference in Nutrients Intake, Dietary Behaviors and Food Intake Frequency of Single- and Non Single-Person Households: The Korea National Health and Nutrition Examination Survey (KNHANES), 2014–2016

Objectives: This study was performed to compare the dietary life of single-and non single-person households in the Korea National Health and Nutrition Examination Survey (KNHANES).Methods: A nationally representative sample of 20,421 19-64-year-olds who had 24hour recall data was taken from the 2014-2016 Korea National Health and Nutrition Examination Survey (KNHANES).Single-and non single-persons were compared for nutrient intake, dietary behaviors, food consumption patterns, nutrition education and confirm nutrition label.Results: The dietary intakes of dietary fiber and iron were lower in single-person households than in non single-person households.The lower the level of education and income, the lower the nutrient intake of single-person households.In the case of those aged 19 to 29, the breakfast skipping rate was higher in single-person households than in non single-person households.The higher the education level, the higher the breakfast skipping rate and the eating out frequency in the single-person households.In the food intake survey, the frequency of healthy food intake in single-person households was much lower than that of non single-person households.The confirmation rate of nutrition labeling was lower in single-person households than in non single-person households.Conclusions: This study shows that single-person households have poorer healthnutritional behaviors than multi-person households.Therefore, a nutrition education program based on the data of this study needs to be developed for health promotion of single-person households.
