About

Filipino Americans (FA) are the second largest (3.4 million) Asian group in the US. and have one of the highest prevalences of obesity and type 2 diabetes mellitus compared to non-Hispanic whites, African Americans and Hispanics. However, FA have been underrepresented in health related research, particularly in diabetes prevention. This proposed pilot study is the first clinical trial to assess preliminary estimates of the short-term effect of the novel social networking diabetes prevention program lifestyle intervention for this high-risk population.

Full description

Filipino Americans (FA) are the second largest (3.4 million) Asian group in the US, and the largest (1.5 million) in California, and have the highest prevalence of obesity and type 2 diabetes mellitus (T2DM) compared to non-Hispanic whites, African Americans and Hispanics. However, there has been little health related research among FA. Improving physical activity (PA) and diet can prevent or delay T2DM, as evidenced by the Diabetes Prevention Program (DPP) lifestyle intervention, resulting in reducing T2DM risks. However, implementing the DPP has been expensive and labor intensive. A more cost-effective approach may be the use of mobile technologies coupled with social networking. Filipinos (95%) are avid mobile phone users and the leading Facebook users. Thus, we propose to test a culturally competent mobile phone-based Diabetes Prevention Program lifestyle and social networking (in-person and virtual) intervention in a pilot 3-month randomized controlled trial (RCT) with a wait list active control design for 50 overweight FA at risk for developing type 2 diabetes.

67 participants in 2 patient groups

Fit and Trim group

Experimental group

Description:

This groups will start with the Filipinos Fit and Trim Weight Loss Program mobile phone based (smartphone) intervention with social networking for 3 months, a pedometer/accelerometer, access to a study private Facebook virtual social networking group, and and 4 in-person intervention session with individually tailored goals for physical activity, diet, and weight. At 3months, the Fit and Trim group will transition to a maintenance phase for 3 months, receive one in-person session for maintenance support (at 4.5 months) and complete the study at month 6.

Treatment:

Behavioral: Filipinos Fit and Trim Weight Loss Program

Pedometer only group

Active Comparator group

Description:

This group will start with the pedometer/accelerometer only to monitor/ track their physical activity step-counts for the initial 3 months. In addition, subjects will receive an educational materials on Hepatitis B and Tuberculosis. At 3 months the pedometer only group will transition to receive the Filipinos Fit and Trim Weight Loss Program intervention (as previously described) for the next 3 months and complete the study at month 6.
