This study aimed to identify the ecological factors influencing obesity among middle school students, including intrapersonal, interpersonal, school, and community…

Background: Embedded within children's weight trajectories are complex environmental contexts that influence obesity risk. As such, the normative environment of body mass index (BMI) within schools may influence children's weight trajectories as they age from kindergarten to fifth grade. Methods: I use 5 waves of the ECLS-K--Kindergarten Class…

Background: The school environment has the potential to influence student body mass index (BMI) through programs and policies.
