We investigate the effects of within-class age differences on adolescents' dietary behaviors. We use a multi-country dataset and find that the youngest students in a class have worse dietary behaviors: they are more likely overweight, they eat fewer vegetables and fruits, they eat more sweets and drink more soft drinks, they tend to skip breakfast, go to bed hungry, and be on a diet. These findings are likely to reflect peer effects: two students with the same absolute age, who were born in the same season, and started school at the same time, have different dietary behaviors because of how their age compares to that of their classmates.
