Cariogenicity and Calories of Meals Served at a Pre-Kindergarten School-Based Meal Program.

Abstract

Purpose: To analyze the cariogenicity of meals served in a pre-kindergarten program and its potential influence on early childhood caries (ECC) risk in socioeconomically disadvantaged children. Methods: This study examined 123 school-provided meals over 43 days at the United Nation Childhood Development Center, part of the Oakland Unified School District pre-kindergarten program. Using cariogenicity indices developed by Evans et al., all items served were assessed for the cariogenic potential of both food and beverages. Results: The mean daily cariogenicity scores were 6.57±1.3 (standard deviation) for food and 2.89±0.78 for beverages. Breakfast foods were significantly more cariogenic than those served for lunch or supper (P<0.05). The mean daily calorie intake was 1,459±336, with lunch containing statistically higher calorie items compared to supper (P<0.05). While liquids may not significantly contribute to caries risk, breakfast foods emerged as a potential concern. Conclusions: This study's findings suggest that the food provided in school meals, particularly breakfast items, may impact early childhood caries risk among socioeconomically disadvantaged children. Given the prevalence of ECC and its societal burden, integrating assessments of food and beverage cariogenicity into school meal planning could be instrumental in mitigating ECC incidence. Collaboration between the United States Department of Agriculture and school districts in considering the cariogenic potential of foods may contribute to improved oral health outcomes in early childhood.
