Study Description
Brief Summary:
The South Asian Community, people with origins in India, Pakistan, Bangladesh, Maldives, Nepal, Sri Lanka, or Bhutan, are more likely to get diabetes, get diabetes at younger ages, and do worse health-wise once they have diabetes than the general population. This study will test the feasibility and community acceptability of a culturally appropriate lifestyle intervention for the prevention of diabetes in the South Asian community. The outcomes of this project could be used to plan larger interventions to prevent diabetes in South Asians, a rapidly growing segment of the US population.

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 16 participants
Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Culturally Tailored Lifestyle Intervention to Prevent Diabetes in South Asians
Study Start Date : April 2010
Primary Completion Date : July 2012
Study Completion Date : July 2012
Arms and Interventions

Arm Intervention/treatment
Experimental: Intervention Arm (Diet and Exercise)
The lifestyle intervention will include a 16-week intervention period, followed by an 8 week, less intensive maintenance period.
Behavioral: Lifestyle Intervention Classes
The intervention will be based on the Diabetes Prevention Program but tailored to the needs of the community based on feedback gathered in focus groups. Classes will be group-based and will use a variety of teaching techniques and group-based work to teach participants about behavior change, diet, and physical activity. Participant will be required to attend one group exercise class per week based on traditional Indian dances and other culturally appropriate activities. In order to reach their weekly exercise goal of 150 minutes or more per week, participants will also be able to attend an additional group exercise class, an organized group walk, do a culturally-tailored work out video created by the study staff, and/or exercise on their own.
