The present study will study the predictors, quality, and impact of Connecticut’s School Wellness Programs (SWP). The aims are to: 1) create, validate, and apply an assessment tool to measure the content and quality of all 2006-07 Connecticut SWPs; 2) view each district’s Index as an outcome variable, and test four categories of predictors; a) 2005-06 sociodemographic variables, b) 2005-06 school nutrition environment ratings, c) 2005-06 composition of the School Health Team creating the SWP, d) 2005-06 district-level student achievement and health; and 3) assess the impact of SWPs by testing each district’s SWP Index as a predictor of several school/district outcome variables. This study involves K-12 schools.
