Introduction: The ubiquitous problem of obesity must be addressed at a young age. The Child Health Initiative for Lifelong Eating and Exercise (CHILE) study tested a multi-level intervention for increasing physical activity and decreasing sedentary time in children enrolled in rural Head Starts in New Mexico. Methods: Sixteen Head Start centers located in predominantly Hispanic or American Indian communities were group randomized to CHILE intervention or control status. Intervention sites received a curriculum, quarterly professional development sessions, weekly materials for parents, and bi-annual Head Start family events, all with an emphasis on increasing physical activity and decreasing television viewing time. Structured interviews regarding physical activity and television viewing behaviors in the home environment were conducted at four time-points with a subgroup of caregivers of 648 children. Multi-level modeling was used to calculate intervention effects on physical activity and television viewing time. Results: Compared with the control group, the relative change in physical activity in the intervention group was 1.49 (95% CI: 0.97 2.29). Dancing increased significantly (2.9; 95% CI: 1.2 7.1; p = 0.02) in the intervention group. Over the study period, mean hours per week of television viewing remained unchanged among the intervention group (0.3 hours + 1.1; p = 0.7) but increased significantly among the control group by 2.8 hours + 1.1 (p = 0.01). Conclusion: The CHILE intervention increased reported physical activity at home among preschool children. Utilizing a socio-ecological model to promote physical activity may prevent the decline of physical activity as children age.
