Association of Eating out Frequency with the Risks of Obesity, Diabetes, and Dyslipidemia Among Korean Adults (P18-058-19)

Abstract

ObjectivesAs the economy grows, eating at home decreases and eating out increases worldwide including Korea. The objective of this study was to clarify the association of eating out frequency with the risks of obesity, diabetes, and dyslipidemia among Korean adults. MethodsThis study was based on a cross-sectional survey of 640 individuals aged 20–69 years in Korea. Anthropometric measurement, dietary intake survey using dietary record and 24h-recalls, blood samples were collected and serum levels of glucose, insulin, and lipids were analyzed. ResultsDaily intakes of energy, fat, protein, cholesterol significantly increased with increase in frequency of eating out (P < 0.001). Energy from carbohydrate significantly decreased with frequency of eating out, while fat and protein increased (P < 0.001). Among the subjects with rare eating out (< once/week), the unadjusted ORs for having overweight or obesity by waist-to-hip ratio, and high LDL-cholesterolemia were significantly higher at 1.82 (95% CI, 1.17–2.83) and 1.63 (95% CI, 1.03–2.57) as compared to the subjects with intermediate eating out (1–2/week). However, after adjusting the confounding factors, significance of these high ORs disappeared. Among subjects with rare eating out, the fully adjusted ORs for high fasting glucose was significantly low at 0.35 (95% CI, 0.16–0.76). ConclusionsBased on the results that the subjects who rarely eat out had a lower fasting blood glucose than the subjects with frequently eating out, it was established that eating out frequency is related to the risks of diabetes.
