Abstract

Background: Estimating the actual impact of eating out on calorie intake poses challenges due to the potential endogeneity of eating out. Controlling for endogeneity is essential to obtain more precise estimates. Aim: This study estimates the effect of eating out on calorie intake, specifically focusing on dinner among the three daily meals. Methods: The endogenous treatment effect model is employed, utilizing restricted-access data from the 2017 to 2020 Korea National Health and Nutrition Examination Survey. To aid model identification, daily precipitation is used as an instrumental variable influencing the decision to eat dinner out. Results: Eating dinner out results in an additional intake of 388.39 Kcal compared to eating at home, whereas the model that does not control for the endogeneity estimates a 261 Kcal increase. The increase in calorie intake from eating dinner out varies significantly depending on individual characteristics. Conclusion: Eating out leads to a substantial amount of calorie intake. Managing the frequency of eating out at a reasonable level could play a crucial role in preventing obesity.

测量外出就餐对卡路里摄入量的确切影响：韩国案例。

背景：由于外出就餐的潜在内生性，估算外出就餐对卡路里摄入量的实际影响是一项挑战。要获得更精确的估计值，控制内生性至关重要。目的：本研究估算了外出就餐对卡路里摄入量的影响，特别关注一日三餐中的晚餐。研究方法利用 2017 年至 2020 年韩国国民健康与营养调查的限制访问数据，采用内生处理效应模型。为帮助模型识别，将每日降水量作为影响外出就餐决定的工具变量。结果显示与在家用餐相比，在外用餐会导致额外摄入 388.39 千卡热量，而不控制内生性的模型估计会增加 261 千卡热量。外出就餐所增加的卡路里摄入量因个人特征不同而有很大差异。结论外出就餐会导致摄入大量卡路里。将外出就餐的频率控制在一个合理的水平，对预防肥胖有重要作用。
