This study aimed to clarify the association between the frequency of dining out and the risk of obesity, diabetes mellitus, and dyslipidemia among Korean adults. This cross-sectional study surveyed 640 participants aged 20–69 years in Korea. Daily intake of energy, fat, protein, and cholesterol significantly increased as the frequency of dining out increased (P < .001). Energy derived from carbohydrates significantly decreased with the frequency of dining out, while that derived from fat and protein increased (P < .001). Among participants who rarely dined out, the fully adjusted odds ratios (ORs) for hyperglycemia were significantly lower at 0.35 (95% CI, 0.16–0.76). Decreased risk of being hyperglycemia among participants who rarely dined out suggests that the frequency of dining out can be related to diabetes risk.

这项研究旨在弄清韩国成年人外出就餐的频率与肥胖，糖尿病和血脂异常风险之间的关系。这项横断面研究调查了640位年龄在20-69岁的韩国参与者。随着外出就餐的频率增加，每日摄入的能量，脂肪，蛋白质和胆固醇显着增加（P <.001）。碳水化合物的能量随进餐的频率显着下降，而脂肪和蛋白质的能量则增加（P<.001）。在很少用餐的参与者中，高血糖的完全调整比值比（OR）明显较低，为0.35（95％CI，0.16-0.76）。很少进餐的参与者中高血糖症的风险降低表明，外出就餐的频率可能与糖尿病风险有关。
