Can Eating Food Offered by Schools Have a Positive Influence on Nutritional Status of Children? An Example from Brazil

Abstract

Objective: Considering that the school environment can impact food consumption and children’s weight, our aim was to evaluate the relationship between the origin of foods consumed at school and children’s nutritional status. Methods: We used data from the nationally representative Brazilian Household Budget Survey of children under 10 years old. The relationship between consumption of foods at school and its origin (offered by the school; taken from home; bought at the canteens) and nutritional status were evaluated using linear (BMI-for-age) and logistic (excess weight and obesity) regression models stratified by type of school (private or public). Results: A total of 95.5% of children referred consumption of food at school, independent of its origin, and 28.0% had excess weight and 10.2% had obesity. In private schools, 70.7% of children ate food taken from home, whereas in public schools, 90.6% of children ate food offered by the school through a school food service program. According to adjusted analyses related to public schools, consuming food offered by the school decreased BMI-for-age and the odds of having obesity. No differences were verified among children from private schools. Conclusion: Eating food offered by public schools seems to be better for Brazilian children’s nutritional status.
