- Objectives
This study aims to examine regional differences in dietary behavior and satisfaction between urban and rural residents in Korea, identifying key factors associated with dietary satisfaction in each group to deepen understanding of these variations.
Methods
The data were obtained from the Consumer Behavior Survey for Food 2022 by the Korea Rural Economic Institute. The analysis involved 6,365 adult participants, using the complex survey χ2-test and complex survey t-tests to compare dietary behavior across regions and complex survey regression analysis to explore factors related to dietary satisfaction. Data were analyzed with R 4.3.1 (for macOS; Posit PBC).
Results
Urban and rural areas differed in consumer characteristics such as gender, age, income, and household type, as well as in food consumption behaviors and in dietary competencies associated with purchasing and intake. Specifically, dining out and processed food consumption were more prevalent in urban areas, whereas home-cooked meals were more frequent in rural areas. Overall, dietary competencies were higher among urban residents. However, there was no significant difference in dietary satisfaction between the two regions. This finding suggests that satisfaction is based on subjective evaluations, with consumers in each region forming satisfaction in ways that align with their environment and lifestyle. Accordingly, the factors contributing to dietary satisfaction differed by region. In urban areas, information utilization competency and maintaining a balanced diet played a significant role in dietary satisfaction, whereas in rural areas, regular mealtimes were more influential. Urban consumers reported higher dietary satisfaction when meals provided a sense of appropriate convenience, whereas rural consumers showed greater satisfaction when meals were shared with family at home.
Conclusion
The findings indicate regional differences in food consumption behaviors and dietary competencies, as well as variations in how consumers achieve dietary satisfaction. These insights provide a foundation for developing dietary policies and programs aimed at improving dietary satisfaction.

- 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 (P < 0.005). Single-person households aged 39 years and younger exhibited lower purchase frequencies for vegetables (P < 0.005) and fish (P < 0.001) and substantially higher frequencies of convenient food purchases (P < 0.001). Additionally, this study identified three distinct single-person household groups based on food purchase pattern: the “nutrition-conscious” group, which exhibited high purchase frequency for fresh foods; the “convenience-seeking” group, which showed high purchase frequency for all types of convenient foods; and the “passive food consumer” group, which displayed relatively low purchase frequency for both fresh foods and convenient foods. The socio-demographic characteristics of single-person households differed significantly across these three groups, with the “passive food consumer” group and “convenience-seeking” group exhibiting lower healthy eating competency (MN(nutrition-conscious group) = 3.68, MP(passive-food-consumer group) = 3.40, MC(convenience-seeking group) = 3.52, P < 0.001), safe eating competency (MN = 3.87, MP = 3.57, MC = 3.77, P < 0.001), and satisfaction (MN = 3.36, MP = 3.23, MC = 3.25, P = 0.04) than the “nutrition-conscious” group.
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.
