Abstract: The authors investigated children's self-reported high-calorie food intake in Grade 5 and its relationship to trends in obesity status and academic achievement over the first 6 years of school. They used 3-level hierarchical linear models in the large-scale database (the Early Childhood Longitudinal Study–Kindergarten Cohort). Findings indicated that frequency of eating fast food in Grade 5 was negatively related to mathematics and reading scores at Grade 5 and to the grow rate in both subjects. Frequency of obtaining salty snacks at school was moderately and negatively related to mathematics performance at Grade 5. School vending machines were not significantly associated with academic achievement patterns or obesity status. These results are informative of trends worth further investigation through prospective models.
