BMI Screening and Reporting in Schools: The Fit Study

The Fit Study is a three-year, cluster-randomized controlled trial that will evaluate the impact of school-based body mass index (BMI) screening and reporting on child health. Seventy-nine California schools will be randomized to one of three groups: 1) BMI screening and reporting, 2) BMI screening, and 3) no BMI screening or reporting (control). Investigators will assess the impact of BMI reporting on students' BMI trajectories over three years. Investigators will also assess the impact of BMI screening on weight-based teasing, feelings of stigmatization, and weight-control behaviors among students.
