PilAm Go4Health Weight Loss Program to Prevent Heart Disease

University of California, San Francisco45 enrolled

Overview

This is a pilot randomized controlled trial intervention to improve lifestyle behaviors (physical activity and health diet) for Filipino Americans with type 2 diabetes on metformin. If the PilAm Go4Health intervention demonstrates potential efficacy, it may identify effective intervention strategies to significantly reduce risks for heart disease risks (i.e., metabolic syndrome) in Filipino Americans.

Filipino Americans are the second largest Asian population and fastest growing racial group in the United States. They have one of the highest rates of insulin resistance (type 2 diabetes = T2DM) and central obesity (fat distributions primarily in the abdominal region). T2DM and central obesity are two of five major risk factors for metabolic syndrome that lead to cardiovascular disease and stroke. Key factors contributing to obesity and T2DM in Filipinos are their physical inactivity, and a diet high in fat and soda intake. However, there are very few research studies on improving health behaviors to reduce risks for metabolic syndrome in Filipino Americans. To help reduce the risk of developing metabolic syndrome in overweight/obese Filipino Americans with T2DM, the proposed project will test a culturally appropriate health behavior intervention program to reduce weight and waist circumference, through increasing physical activity, and lowering fat and sugar sweetened beverage intake. This intervention uses a mobile phone health app and social networking to encourage adherence to target health behaviors. The goals are to: 1. To assess feasibility and acceptability of the culturally appropriate PilAm Go4Health Weight Loss Program 2. To obtain preliminary estimates of the effect of the intervention on weight 3. To conduct post-program process evaluations too improve the intervention relevancy for the target population.

Interventions

PilAm Go4Health Weight-loss ProgramBEHAVIORAL

This is a 3-month lifestyle intervention program promoting weight loss through physical activity and health diet using a mobile health application (app), pedometer to track daily step-counts, and social networking (in-person and virtual social networking through Facebook) to reduce risks for metabolic syndrome in Filipino Americans with type 2 diabetes on metformin. Subjects will be asked: 1) to use a mobile app diary every day to input their weight, and calories (food and drink intake) and 2) wear a pedometer everyday to monitor their physical activity (step-counts).

Active ControlBEHAVIORAL

This is a 3-month active control using a pedometer only without any education related to wt loss, physical activity, health eating, or tracking healthy behaviors

Outcomes

Primary Outcomes

Feasibility for Participant Enrollment and Retention

Able to enroll at least 20 eligible participants per arm (measured by count), and retain at least 80% of enrolled participants in each arm

Time frame: Baseline to 6-months

Secondary Outcomes

Weight Change in Kilograms

weight change in kilograms over a 3 month period. Intervention group will have a significantly greater reduction in weight change compared to the active control from baseline to 3-months

Time frame: Baseline to 3 months

Percent Change in Weight (kg) From Baseline and 3 Months

100 x change in weight (kg) at 3 months divided by weight (kg) at baseline. Intervention group will have a significantly greater reduction in % weight change compared to the active control from baseline to 3-months.

Time frame: Baseline to 3 months

Change in Waist Circumference

Change in waist circumference over time within groups

Time frame: baseline to 3 months
