Objectives
This study evaluated the nutrition quotient for preschoolers (NQ-P) and analyzed the impact of key factors, such as caregivers’ food literacy, social support, and food environment, on the eating habits of preschool children in Korea. This study also sought to provide foundational data for developing tailored nutrition education programs by identifying the nutrition education needs of caregivers.
Methods
This study was conducted among caregivers of preschool children (aged 0–6 years) using an online self-administered survey conducted from August 22 to August 28, 2023. A total of 1,116 survey responses were analyzed. This study assessed children’s NQ-P score, caregivers’ food literacy, social support, food environment, and nutritional education needs. Data were analyzed using SPSS 29.0 (IBM Co.).
Results
The average NQ-P score for preschool children was 52, showing a tendency for the balance score to decrease and the moderation score to increase with age. Children from rural and low-income areas exhibited significantly lower NQ-P scores. Caregivers’ food literacy was higher in urban and higher-income groups. Multiple regression analysis revealed that social support, food literacy, income, and food environment significantly affected children's NQ-P scores. The effectiveness of nutrition education varied based on the income level, with nutrition education on healthy eating being the most preferred topic for preschool children.
Conclusion
This study confirmed that caregivers’ food literacy and social support significantly affected preschool children’s nutritional status. This suggests a need for tailored nutritional education and dietary support policies, particularly for low-income and rural populations.

Program Evaluation using the RE-AIM Framework: A Systematic Review and Application to a Pilot Health Promotion Program for Children
Ji-Eun Lee, Jae Eun Shim, Kirang Kim, Jae-Heon Kang, Ji-Yun Hwang
Korean J Community Nutr 2022;27(4):296-308.   Published online August 31, 2022
DOI: https://doi.org/10.5720/kjcn.2022.27.4.296
AbstractAbstract PDF
Objectives
This study aimed to develop evaluation criteria for the elementary-school-based health promotion program using the RE-AIM framework and to examine their feasibility.
Methods
Previous evaluation studies on health interventions for elementary-school students using the RE-AIM framework were reviewed systematically to identify appropriate evaluation criteria. A diet and physical activity intervention based on the transtheoretical model was implemented in a pilot study using the “Happy Me” application. The feasibility of using the RE-AIM framework to evaluate it was examined.
Results
The review yielded the following evaluation criteria: “reach,” the ratio of participants out of the total target population; “efficacy/effectiveness,” the difference in outcomes between the intervention and control groups, or between a pre- and post-test; “adoption,” the rate of use of the program and participation in the next stage of the program; “implementation,” the progress on the program components; “maintenance,” the participants’ and teachers’ intention to continue using the program. The pilot study reached 76.6% of the targeted population. The intake of sugar-sweetened beverages decreased (P < 0.0001), and the duration of walking increased (P < 0.0001). Other indicators could not be evaluated; therefore, potential indicators were suggested.
Conclusions
This study produced feasible evaluation criteria for elementary-school-based health promotion using the RE-AIM framework. Nevertheless, the feasibility needs to be validated with a broader range of studies and long-term interventions.

Basic Concepts and Detailed Dimensions of Food Security and Related Indicators for Policy Development and Evaluation
Sohyun Park, Ji-Yun Hwang, Jae Eun Shim, Kirang Kim
Korean J Community Nutr 2021;26(6):429-440.   Published online December 31, 2021
DOI: https://doi.org/10.5720/kjcn.2021.26.6.429
AbstractAbstract PDF
Objectives
Standardized guidelines and reference points for a food security policy are necessary to guarantee that basic social safety nets work properly. Therefore, this study aimed to explore the basic concepts and detailed dimensions of food security, including the potential relevant indicators, and sought to establish standardized well-being baselines.
Methods
A literature review and 14 expert roundtable discussions were carried out to analyze and extract the key concepts of food security. After determining these concepts and detailed dimensions of food security, a conceptual framework was modeled. Then, indicators for each local government that could be monitored and evaluated for each sub-area were suggested.
Results
The concept of food security was defined as follows: Individuals should be provided with sufficient, safe, and quality food, which should be accessible to the community and available for use to achieve health and well-being. In addition, food security should be ensured sustainably in a changing environment. Four dimensions were suggested while conceptualizing food security. First, sufficient food, which means sufficient food supply in quantity, quality, and safety. Second, equitable food which includes creating environments in which high-quality and safe food can be purchased at an appropriate price and can be provided regardless of the socioeconomic gap. Third, healthy food which should be provided to promote people’s health and happiness through the eco-friendly consumption of food. Fourth, sustainable food, which can be supplied in a sustainable manner and as part of an eco-friendly food system that considers the conservation of natural environments.
Conclusions
The basic concepts and detailed areas of food security including the potential indicators proposed in this study, may be useful for developing and implementing various policies and programs to support food and nutrition security in the future.
