Background
The Pacific Islands is an area with one of the world's highest prevalence of obesity and diabetes. The Republic of the Marshall Islands (RMI) is an independent country of the Micronesian that extends along latitude 4 to 18 degrees north. In the past, several studies reported regarding the prevalence of diabetes among the people of the Pacific Islands. However, there is no report yet with respect to diabetes in Majuro, the capital of RMI. In RMI, diabetes and obesity are also recognized to be a serious problem, but the present state of affairs prevents an understanding of the situation.
Objectives
The purpose of the present study was to investigate the present situation and the prevalence of diabetes and obesity in Majuro.
Methods
The participants were Marshallese visited our thyroid cancer-screening program. Among those participants who undertook thyroid cancer screening, the Body Mass Index (BMI) and hemoglobinA1c (HbA1c) levels were taken of 850 participants. Participants with an HbA1c level of 6.5% or more were put into the diabetes group and participants with a BMI of 30 and over were the obese group. Prevalence was adjusted using the Majuro population based on 1999 national census and using world standard population of Segi.
Results
The age-adjusted prevalence of diabetes in aged 20 years and over in Majuro was 22.1%. After standardization, the prevalence was 31.0%.
Conclusion
The results suggest there is a high rate of diabetes in RMI similar to other pacific islands. It could be concluded, based on this research, that there is a crisis situation with regards to diabetes in the RMI. There is also a need for epidemiological research to be on a random sample of the population.
