Healthy Body Healthy Souls in the Marshallese Population

Background and Rationale Disparities in type 2 diabetes, pre-diabetes, and obesity among the Marshallese and Pacific Islanders. This study focuses on the Marshallese living in Arkansas. The Marshallese are a Pacific Islander population experiencing significant health disparities, with some of the highest documented rates of type 2 diabetes of any population group in the world. Our review of local, national, and international data sources found estimates of diabetes in the Marshallese population (in the US and the Republic of the Marshall Islands) ranging from 20% to 50%, compared to 8% for the US population and 4% worldwide. While national prevalence data are limited, 23.7% of Pacific Islanders surveyed by the Centers for Disease Control and Prevention (CDC) in 2010 reported a diagnosis of type 2 diabetes - more than all other racial/ethnic groups. Our preliminary research, which included health screenings with the Marshallese community in Northwest Arkansas (n = 401), documented extremely high incidence of diabetes (38.2%) and pre-diabetes (32.4%). Our pilot data also revealed similar disparities in obesity, one of the strongest risk factors for diabetes; 90% of Marshallese participants were classified as overweight or obese. Further compounding these significant disparities, Pacific Islanders living in the US are less likely than other racial/ethnic groups to receive preventive or diagnostic treatment or diabetes education. This study addresses an urgent need for interventions to reduce obesity and diabetes disparities in the Marshallese community and will employ a culturally appropriate, multilevel approach. The scientific premise of our study includes four main points. First, the Marshallese in Arkansas suffer from a significant and disproportionate burden of type 2 diabetes and lack access to effective prevention and treatment due to a dearth of research with Pacific Islanders.Second, the association between weight gain and risk for type 2 diabetes is strong. Overweight/obesity is considered the strongest modifiable risk factor for type 2 diabetes, and even a modest reduction in weight (5-10%) is clinically meaningful. Third, research demonstrates the effectiveness of multi-level lifestyle interventions in reducing weight and the onset and impact of diabetes. Fourth, to be effective among Pacific Islanders, interventions must be developed to address influences at multiple levels and should be culturally adapted to incorporate Pacific Islanders' worldviews and cultural values. Prior research indicates the importance of using a Community Based Participatory Research (CBPR) approach to understand and integrate cultural nuances during the cultural adaptation process and implementation of multilevel interventions. A CBPR approach is also essential to conducting ethical, valid health research in populations whose health beliefs and behaviors have been shaped by historical trauma. Finally, churches are primary social institutions of Pacific Islander health. Faith-based interventions are effective at improving behavioral and anthropometric outcomes within collectivistic communities and therefore hold great promise for Marshallese and other Pacific Islanders.
