Evaluation of young children’s dietary behaviors by parental growth concern levels in Gyeonggi area: a descriptive study: Youn-Rok Kang, Hyung-Sook Kim; Korean J Community Nutr 2026;31(1):75-86. Published online February 28, 2026; DOI: https://doi.org/10.5720/kjcn.2025.00269

Abstract PDF: Objectives
This study investigated differences in dietary habits, lifestyle patterns, and feeding- related developmental issues among Korean preschool children based on their parents’ levels of growth concern, and examined the associations between parental growth concern and children’s eating behaviors.
Methods
A cross-sectional study was conducted with parents of children aged 1–5 years residing in Gyeonggi Province, Korea. Participants were classified into high, moderate, and low growth concern groups using the children’s dietary screening test. Data were collected on the children’s anthropometric status, lifestyle routines, dietary intake patterns, eating behaviors, and mealtime media exposure.
Results
Children in the high growth concern group showed a higher prevalence of underweight; irregular sleep and mealtime routines; and more frequent eating difficulties, including picky eating, slow eating, and oral processing problems. Mealtime media exposure was associated with lower fruit and vegetable intake and higher consumption of processed and sugar-rich foods. Higher parental growth concern did not correlate with healthier dietary or lifestyle outcomes.
Conclusion
Preschool children’s dietary behaviors and routines differed according to the parents’ levels of growth concern. Higher levels of parental concern were associated with increased feeding difficulties and greater mealtime media exposure. These findings suggest that excessive concern may contribute to maladaptive eating patterns in children. Evidence- based parental guidance and structured nutrition education are essential to promote healthy growth and eating behaviors during early childhood.

Nutrition quotient for preschoolers and key impacting factors in Korea: a cross-sectional study on food literacy, social support, and the food environment of primary caregivers: Danbi Gwon, Ji-Yun Hwang, Jieun Oh; Korean J Community Nutr 2025;30(1):16-26. Published online February 28, 2025; DOI: https://doi.org/10.5720/kjcn.2024.00311

Abstract PDF

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.
