Background: To discover the association between eating alone and diet quality among Korean adults who eat alone measured by the mean adequacy ratio (MAR), METHODS: The cross-sectional study in diet quality which was measured by nutrient intakes, indicated as MAR and nutrient adequacy ratio (NAR) with the Korean National Health and Nutrition Examination Survey (KNHANES) VI 2013-2015 data. Study population was 8523 Korean adults. Multiple linear regression was performed to identify the association between eating behaviour and MAR and further study analysed how socioeconomic factors influence the diet quality of those who eat alone.

Results: We found that the diet quality of people who eat alone was lower than that of people who eat together in both male (β: - 0.110, p = 0.002) and female participants (β: - 0.069, p = 0.005). Among who eats alone, the socioeconomic factors that negatively influenced MAR with the living arrangement, education level, income levels, and various occupation classifications.

Conclusions: People who eat alone have nutrition intake below the recommended amount. This could lead to serious health problems not only to those who are socially disadvantaged but also those who are in a higher social stratum. Policy-makers should develop strategies to enhance diet quality to prevent potential risk factors.

Keywords: Diet quality; Eating alone; MAR; NAR; Socioeconomic status.
