Objectives:
Food neophobia in children is often associated with limited exposure and familiarity to some foods. Cooking-based nutrition education (CBNE), which promotes acceptance through direct experience, may support the development of healthy eating habits. This study aimed to develop and implement a standardized CBNE program for school-aged children in Seoul, South Korea, and to evaluate its effectiveness by assessing changes in raw vegetable intake. Raw vegetable intake is an early indicator of the effectiveness of nutrition education on diverse topics in promoting healthy eating habits.
Methods:
A single-group pre–post study was conducted with 37 children aged 6–11 years who participated in a 2-day CBNE program in October 2023. The participants completed pre- and post-education questionnaires and raw vegetable intake assessments. Four low-preference vegetables (bell pepper, carrot, cucumber, and tomato) were selected and served raw (25 g each) before and after the program. Intake changes were analyzed using paired t-tests, and Pearson’s correlation and hierarchical regression analyses were performed to identify predictors.
Results:
Total raw vegetable intake significantly increased post-education (P = 0.008), particularly for carrots (P = 0.023). By subgroup, raw vegetable intake significantly increased in girls, upper-grade students, and those who consumed four or more vegetable side dishes per meal. Hierarchical regression analysis revealed that while vegetable preference was initially significant, vegetable-related experiences (β = 0.395, P = 0.026) and diversity of vegetable side dishes per meal (β = 0.403, P = 0.032) were stronger predictors in the final model (adj R2 = 0.333).
Conclusion
The CBNE program may enhance vegetable intake in children. Although preference remained the strongest individual factor, vegetable experience and the diversity of vegetable side dishes per meal had a greater combined effect. These findings underscore the importance of repeated and diverse exposure, not only by supporting previous studies that link such exposure to increased intake but also by suggesting that environmental support may be essential for sustaining healthy eating habits.

Korean Journal of Community Nutrition 2025;30(4):286-295
Objectives:
In this study, we identified the current status of meal and nutritional management in elderly care facilities and analyzed the educational needs of employees, with the goal of proposing effective support strategies for nutritional management and to suggest directions for developing customized educational content.
Methods:
Between May and June 2024, we conducted nine focus group interviews with 22 participants recruited from 10 cities across four major regions of Korea, including 13 employees of children and social welfare meal management support centers and nine employees of elderly care facilities.
Results:
Our findings revealed that supporting algorithm-based dietary planning, improving communication with caregivers, and providing flexible, practical education tailored to facility conditions, are key elements for enhancing nutritional management in elderly care facilities. To facilitate the translation of these insights into practice, it will be necessary to strengthen collaboration between centers and facilities, combined with efforts to improve the operational environment for applying the algorithm and providing continuous educational support.
Conclusion
The findings of this study emphasize the importance of on-site education and sustainable support strategies based on the diet and nutritional management status and education needs of elderly care facilities. Strengthening practical education, communication systems, and center–facility collaboration is required, and future research needs to verify the efficacy of these measures and define a sustainable support system based on quantitative analysis.

Objectives:
The dietary habits of school-aged children play a critical role in their growth and development, and are strongly influenced by the home environment. Household income is closely associated with caregivers’ food literacy, social support, and food environment. This directly affects the nutritional status of children. This study aimed to provide evidence to inform policies and educational programs for improving dietary habits in children, and to establish a foundation for tailored support strategies for low-income families.
Methods:
This cross-sectional study included 846 primary caregivers of school-aged children from 17 regions across Korea, recruited through an online survey. Household income, caregivers’ food literacy, social support, and food environment were assessed. Nutritional status in children was measured using the Nutrition Quotient for Children (NQ-C). Statistical analyses included descriptive statistics, chi-square tests, one-way analysis of variance (ANOVA), analysis of covariance (ANCOVA), correlation analyses, and multiple linear regression.
Results:
Caregivers from higher income households demonstrated significantly greater food literacy and social support (P < 0.001). Children from these households showed high balance scores and a large proportion of these children were in the “high” NQ-C grade. The NQ-C score in children was positively correlated with food literacy (r = 0.425), social support (r = 0.471), and the food environment (r = 0.235) (P < 0.001). Multiple regression analysis showed that food literacy (β = 0.256) and social support (β = 0.348) were significant predictors of nutritional status in children.
Conclusion
This study confirmed that the nutritional status in children is not only determined solely by household income but is also mediated by caregivers’ food literacy, social support, and food environment. These findings highlighted the limitations of providing only economic support. The findings underscore the need for multifaceted interventions such as strengthening parental nutrition education, expanding social support networks, and improving access to healthy foods.

Purpose:
This study examined the evaluation indicators and frameworks for assessing the effectiveness of the Center for Children’s and Social Welfare Foodservice Management.
Methods:
A qualitative research design was used, including focus group discussions and indepth interviews cond1ucted with 26 stakeholders, such as center staff, community nutrition experts, and performance evaluation specialists. The interviews were recorded with the participants’ consent, and the transcribed data were analyzed using framework analysis to identify key patterns.
Results:
The findings highlight several critical issues in the current evaluation framework, including over-reliance on satisfaction surveys, insufficient utilization of checklist data, and a lack of long-term outcome measures. The participants recommended improving satisfaction surveys by diversifying the respondents and refining methodologies. Systematic data management was also highlighted as essential, particularly for data collected by center nutritionists during site visits. These data are crucial for evaluating the effectiveness of overseeing and educating cooks and staff in children’s and social welfare facilities. For the long-term outcome indicators, the participants suggested integrating national health datasets to monitor the food consumption patterns, such as fruit and vegetable intake or sugar-sweetened beverage consumption among children, and tracking medical expenses or hospitalization rates for elderly daycare center users. Well-designed intervention studies were recommended to develop more robust evaluation indicators, particularly for assessing the impact of the centers on the health and quality of life of the elderly.
Conclusion
Therefore, comprehensive and standardized evaluation systems should be implemented to enhance operational efficiency and service quality. The proposed evaluation scheme can better evaluate and support the health and well-being of vulnerable populations, including children, the elderly, and individuals with disabilities, by aligning these systems with the centers’ mission of ensuring safe and nutritious food services.

Korean Journal of Community Nutrition 2022;27(3):177-191
Objectives:
Recent epidemiological data reported that young adults in their 20 ~ 30s are a vulnerable population with unhealthy dietary practices and a few signs of deteriorated health indicators. However, there are no dietary guidelines that are specifically developed for the young adult population. This study introduces some data collection tools that are mostly used in the service design field, and demonstrates how these tools can be used in nutrition research for developing dietary guidelines for specific target groups.
Methods:
To understand the context of food choices among young people, 39 people were enrolled to complete a probes booklet. Thematic analysis and word cloud were performed to capture the main themes from the probes and a persona was developed based on the findings.
Results:
Data from the probes enabled us to grasp the various contextual meanings of eating practices among young people. Most participants understand what a healthy diet is and often have a willingness to practice it. However, there were very few participants who were following the practices. We created four types of persona for developing dietary guidelines: healthy eating, emotional eating, convenient eating, and trendy eating.
Conclusions
Probes and persona were used in order to understand the lives of young adults and develop targeted messages. We hope that this introduction will be helpful to researchers who are looking for new ways of understanding their target population in the field of community nutrition.

Serosurveillance studies reveal the actual disease burden and herd immunity level in the population. In Seoul, Korea, a cross-sectional investigation showed 0.07% anti-severe acute respiratory syndrome coronavirus-2 antibody seropositivity among 1,500 outpatients of the university hospitals. Low seroprevalence reflects well-implemented social distancing.Serosurveillance should be repeated as the pandemic progresses.

BACKGROUND: Few reports have documented the clinical characteristics and treatment outcomes of adult patients with Elizabethkingia meningoseptica infection. METHODS: Medical records of patients over 18 years of age and suspected of having an E. meningoseptica infection from March 1, 2006 to February 28, 2013 were reviewed retrospectively. Their clinical characteristics, antimicrobial susceptibility results, and treatment outcomes were analyzed. RESULTS: E. meningoseptica was isolated from 30 patients. Median age was 68.5 years, and infections were more frequent in males (17, 56.7%). The most common isolation source was sputum (23, 76.7%), and pneumonia was the most common condition (21, 70%) after excluding two cases of colonization. This bacterium was most susceptible to minocycline (27, 90%) and fluoroquinolones, including levofloxacin (20, 66.7%) and ciprofloxacin (18, 60%). The mortality rate due directly to E. meningoseptica infection was 20% (6/30), and uncontrolled pneumonia was the only cause of death. After isolating E. meningoseptica, the numbers of patients with pneumonia (9/9, 100% vs. 12/21, 57.1%), history of hemodialysis (5/9, 55.6% vs. 3/21, 14.3%), tracheostomy (8/9, 88.9 vs. 10/21, 47.6%), and median Charlson comorbidity index score (6 [range, 3-9] vs. 4 [range, 0-9]) were significantly higher in non-survivors than those in survivors (p < 0.05, for each). However, only 12 (40%) patients received appropriate antibiotics. CONCLUSIONS: E. meningoseptica infection most commonly presented as pneumonia in adults with severe underlying diseases. Despite the high mortality rate, the rate of appropriate antibiotic use was notably low.
