Understanding the charactersitics and types of single-person households based on food purchase frequencies in Korea: a cross-sectional study using the 2023 Consumer Behavior Survey for Foods.

Objectives: This study investigated the differences in food purchase frequency among single-person households by gender and age group and explored the characteristics of single-person household groups according to their food purchase patterns. Methods: Utilizing data from the 2023 Consumer Behavior Survey for Foods conducted by the Korea Rural Economic Institute, this study examined food purchase frequencies among 966 single-person households. Data were analyzed using Rao-Scott chi-square tests, ANCOVA, ANOVA, and K-modes hierarchical cluster analysis. Results: Significant differences were observed in the food purchase frequencies of single-person households for fresh and convenient food. Women displayed higher purchase frequencies for fish, vegetables, and fruits, whereas men showed higher purchase frequencies for convenient foods ( Conclusion: This study underscores the need for targeted nutrition programs to address the unique needs of single-person households depending on their characteristics. Specifically, this study highlights the importance of targeted interventions for "convenience-seeking" and "passive food consumer" to promote dietary competency and encourage healthy dietary behavior.
