Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Change in weight from baseline to 3-month and 12-month follow up

    Change in weight from baseline to 3-month and 12-month follow up.

    baseline, 3-months, 12-months

  • Change in physical functioning from baseline to 3-month and 12-month follow up

    Change in number of feet walked in 6 minutes from baseline to 3-month and 12-month follow up.

    baseline, 3-months, 12-months

Secondary Outcomes (3)

  • Blood pressure

    baseline, 3-months, 12-months

  • Physical Activity Frequency

    baseline, 3-months, 12-month

  • Fat in Diet

    baseline, 3-months, 12-months

Study Arms (2)

Weight loss maintenance intervention delivered via DVD

EXPERIMENTAL

Weight loss maintenance intervention delivered via DVD (without a peer facilitator) to employee participants within the respective worksites randomized to this arm. Using DVD technology, a total of 11 additional sessions (designed for weight loss maintenance) over a 9-month period will be delivered to the participants of this arm using DVD-produced lessons of PILI Maintenance

Behavioral: Weight loss maintenance intervention delivered via DVD

Weight loss maintenance intervention Face-to-Face

EXPERIMENTAL

The PILI Maintenance delivered face-to-face in a group setting by trained peer facilitators to employee participants within the respective worksites randomized to this arm. The trained peer facilitator will deliver a total of 11 additional sessions (designed for weight loss maintenance) over a 9-month period, meeting bi-weekly for the first 2 months and then monthly for the remaining 7 months with a group of 8 to 15 participants.

Behavioral: Weight loss maintenance intervention face-to-face
