School Worksite Weight Gain Prevention Intervention Study - Full Text View

Purpose

The proposed site-level randomized trial will test the effectiveness of a work site intervention based on an ecological framework at preventing weight gain among high school employees in Massachusetts. The investigators hypothesis is that the intervention will positively impact healthy dietary patterns and physical activity, perceived organizational commitment, coworker influences, social support, self-efficacy, and self-control, which in turn will positively mediate or moderate the positive associations between the intervention and the primary outcomes (change in weight, BMI, and waist circumference). If effective, the intervention is designed to be generalizable to high school settings across the country and has the potential to reduce the morbidity, mortality and economic costs of overweight and obesity in this important population.

Arms	Assigned Interventions
Experimental: Step Ahead Promotion of weight gain prevention among teachers and staff in public high schools through Step Ahead, a comprehensive intervention targeting three levels suggested by the ecological framework health behavior change: organizational school level, interpersonal level, and individual level.	Behavioral: Step Ahead Promotion of weight gain prevention among teachers and staff in public high schools through Step Ahead, a comprehensive intervention targeting three levels suggested by the ecological framework health behavior change: organizational school level, interpersonal level, and individual level.
Active Comparator: Basic Intervention Promotion of weight gain prevention among teachers and staff in public high schools through receipt of the workbook print materials and access to website similar to the enhanced intervention.	Behavioral: Basic Intervention Promotion of weight gain prevention among teachers and staff in public high schools through receipt of the workbook print materials and access to website similar to the enhanced intervention.
