Abstract:
Objective:To establish Chinese diet balance index for preschool children（DBI_C), and evaluate the dietary quality of Chinese preschool children.Methods:DBI_C was established according to the methods establishing DBI_16 and the recommended intake of different kinds of food for preschool children. Three scoring methods [low bound score （LBS), high bound score （HBS), diet quality distance （DQD)] were used to evaluate the dietary quality of preschool children selected from the 2010-2012 China National Nutrition and Health Surveillance. Scores [ P50（ P25, P75)] were compared to reflect the diet quality of preschool children in different regions. Results:DBI_C scores for cereals of preschool children from big city, middle and small city, normal rural area, and poor rural area were 0.0 （-2.0, 6.0), 0.0 （0.0, 6.0), 4.0 （0.0, 10.0), and 10.0 （2.0, 12.0), respectively （ P<0.001), indicating that the intakes of cereals of preschool children were adequate. Scores for animal food of preschool children from four types of location were 0.0 （-2.0, 2.0), 0.0 （-6.0, 2.0), -4.0 （-6.0, 0.0), and -6.0 （-8.0,-2.0), respectively （ P<0.001), indicating that the intakes of animal food of rural preschool children were inadequate. Scores for vegetable and fruit, milk and soybean were both less than 0 （ P<0.001), indicating that the intakes of these food were insufficient in both urban and rural area. Scores of LBS, HBS and DQD were 24.0 （18.0, 30.0), 8.0 （3.0, 13.0) and 33.0（26.0, 39.0). Children without diet insufficient problem in four type of location accounted for 30.8%, 7.8%, 4.3% and 1.1%, respectively （ P<0.001). Children without diet excessive problem accounted for 54.0%, 57.3%, 52.9% and 32.6%, respectively （ P<0.001). Children without diet imbalance problem were 10.6%, 1.1%, 1.3% and 0.3%, respectively （ P<0.001). Conclusion:Diet quality of urban preschool children is better than that of rural preschool children. Dietary imbalance is the main problem among Chinese preschool children.
