ABSTRACT: Abstract There is a high prevalence of type 2 diabetes mellitus (T2DM) among the Marshallese in the Republic of the Marshall Islands (RMI). However, no prior literature has examined self-reported health indicators, self-management activities, barriers to care, diabetes knowledge, and family support for diabetes management. This study examined health indicators among participants with T2DM (n=41). Clinical measures included glycated hemoglobin (HbA1c) and fasting glucose level, blood pressure, pulse pressure, and cholesterol levels. Survey items included participants’ self-reported health indicators, self-management activities, barriers to care, diabetes knowledge, and family support for diabetes management. Clinical health indicators demonstrate the poor health status of the participants, including uncontrolled fasting glucose levels and HbA1c levels (61.9% had an HbA1c ≥9.0%), high blood pressure, elevated pulse pressure (65.9% had pulse pressure >40 mmHg), and high total cholesterol. Participants report limited knowledge and participation in diabetes self-management behaviors, limited family support, and faced numerous barriers to medical care, medications, and supplies. This study provides insight into the T2DM disparities experienced by Marshallese in the RMI. This study is the first to document the self-reported health indicators, self-management activities, barriers to care, diabetes knowledge, and family support for diabetes management. The results highlight the need for T2DM management interventions and will be used to refine a culturally adapted intervention for delivery in the RMI.
