Evaluation of dietary intake in Korean adults according to energy intake from eating-out: Based on 2013~2014 Korea National Health and Nutrition Examination Survey / 한국영양학회지

ABSTRACT

PURPOSE: The objective of the present study was to evaluate nutrient and food group intakes in Korean adults according to energy intake from eating-out. METHODS: This study was a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey, and study subjects were 5,186 males (2,151) and females (3,035) aged 19~64 years. Energy intake from eating-out was analyzed using the 24-hour dietary recall method, and groups were classified by quartile according to energy intake from eating-out. RESULTS: Subjects who had more energy intake from eating-out tended to be younger, highly educated, have a higher income, and have higher alcohol consumption. Total energy intake and fat intake density of the highest quartile group of energy intake from eating-out were higher than those of the other groups. However, fiber, vitamin B1, calcium, phosphorus, potassium, and iron intake density levels were significantly lower in the highest quartile group of energy intake from eating-out. The highest quartile group of energy intake from eating-out consumed significantly more meat and beverages compared to the other groups. In addition, regarding diet quality (Index of nutritional quality), significantly lower vitamin B1, calcium, phosphorus, and iron levels were observed in the highest quartile group of energy intake from eating-out compared to those in the other groups. CONCLUSION: In conclusion, in Korean adults, consumption of eating-out decreased dietary quality, including vitamin B1, calcium, phosphorus, and iron levels. Further studies are needed to confirm these findings.
