FEATURED CNP RESEARCH SUMMARY

Associations between meal companions and obesity in South Korean adults

Jeong & Jang (2020) inspected the data from the 2013-2017 Korean National Health and Nutrition Examination Survey (KNHANES) involving 23,494 adult participants and their relationship between meal companions and obesity. Participants were first divided into three categories: dinner with family, dinner with others, and alone. A multinomial logistic regression analysis revealed that people who ate dinner with others or alone had a higher obesity risk than those who had family dinners. This was the case regardless of their breakfast companion. Moreover, those adults who had daily meals outside of their homes had a greater risk of becoming obese than those who ate dinners with others or with family. It was also discovered that regular drinking increases obesity risk, as seen in those who engaged in weekly heavy drinking than those who did not drink. This investigation highlights the benefit of family dinners over having dinner alone or with others, which could motivate dieters to have more frequent family dinners.
