Abstract

Objectives: To examine self-reported exposure to a physical activity (PA) promoting intervention and changes to school environmental PA factors.

Methods: Randomly selected 8(th) grade girls in year 2 (N = 3469) and year 3 (N = 3462) completed surveys on exposure to the health education, PE components, PA programming, and PA supporting messages. Girls' perceptions of their school-environment and an assessment of school environmental factors by principals in support of PA also were measured. Analysis included generalized linear mixed models with random effects for site and school comparing intervention and control schools.

Results: Year 2 intervention girls reported greater exposure to all 4 components of the intervention compared to control school girls. In year 3, differences by treatment disappeared in all but 2 components.

Conclusions: Intervention girls were exposed to TAAG in year 2 with effects diminishing in year 3.
