Abstract

Pathways is a school based study designed to determine if a culturally appropriate intervention involving physical activity, food service, classroom curriculum and family involvement will result in a lower percent body fat (PBF) in American Indian children in intervention schools at the end of a three year period. Forty elementary schools from six tribes will be randomly assigned to receive the intervention or serve as controls. With 80% power, the study will be able to detect a difference in mean PBF of approximately 3%. Randomization will be stratified by field center and baseline BMI. Data analysis will use the mixed linear model with school as a random effect and intervention and baseline PBF as fixed effects. Imputation of missing values will allow for an intention to treat analysis. Issues considered in denning the intervention design included: school size, anticipated compliance, contamination, and assumptions regarding missing data.
