Abstract

BACKGROUND/OBJECTIVES
In Korea, childcare facilities providing food service for 100 or more children are required to employ dietitians, while those serving fewer than 100 children must register with the Center for Children's Foodservice Management to receive dietary guidance from its dietitians. This study compared the dietary intake of children who had daycare meals and those who did not to evaluate the impact of dietitian-managed nutritional services.
SUBJECTS/METHODS
This study analyzed the 24-h recalls from 706 children aged 3–5 yrs using the data from the 2016–2019 Korea National Health and Nutrition Examination Survey. Among them, 578 children had daycare meals, while 128 did not. The differences in energy contributions from meals and snacks, nutrient intake, and the amount and number of servings of various food groups consumed by these two groups were investigated.
RESULTS
The daycare meal group (DMG) showed a significantly higher intake of protein, thiamin, niacin, sodium, potassium, and iron during lunch and higher protein and sodium consumption during snack times after adjusting for the energy intake compared to the non-daycare meal group (NDMG). On the other hand, the DMG consumed less sugar and fat during lunch and snack times and less vitamin C during snack times. The DMG also showed higher consumption of legumes and vegetables but lower consumption of sweets during lunch and in the total daily consumption. The overall dietary quality assessed by the mean adequacy ratio was significantly higher among the DMG than in the NDMG CONCLUSION: Children were provided with higher-quality meals in daycare settings than in other environments. These results underscore the importance of nutrition management by dietitians. These findings also highlight the need for nutrition education for caregivers, particularly increasing vegetable intake and reducing sugar-sweetened beverage consumption.
