PILI at Work a 5-Year Controlled Intervention Trial: Testing DVD Versus Group Delivery of a Weight-Loss Maintenance Intervention in Native Hawaiian- Serving Worksites

Summary

The PILI @ Work project is a 5 year randomized control trial to adapt a weight loss program for the employees of Native Hawaiian-serving organizations in Hawai'i. The study has two specific aims:

Specific Aim 1: To adapt and implement a weight loss and weight loss maintenance program in Native Hawaiian-serving organizations, working with employee representatives to determine how the intervention can be best implemented with employees at the worksites. Specific Aim 2: Among employees participating in the program, to test whether weight loss maintenance program in DVD format is as effective as the weight loss maintenance program in a group face to face format in maintaining weight loss for employees who complete weight loss program.

The investigators hypothesize that the PILI @ Work interventions can be effectively adapted and implemented in a worksite settings with active participation by employees and employers. The investigators also hypothesize that overweight (BMI ≥ 25) and obese (BMI ≥ 30) employees who complete weight loss portion of the intervention, and are randomized to received the weight loss maintenance intervention via DVD will have similar success at maintaining weight loss compared to those randomized to PILI Maintenance in group meetings or settings. The investigators hypothesize that will will also be true for physical functioning,blood pressure, daily self-weighing, low to moderate fat and low calorie diets, and daily physical activity.
