Prevalence of Diabetes in Nepali-Speaking Bhutanese Americans Living in the Greater Harrisburg Area

Abstract

Members of the Nepali-speaking Bhutanese refugee community had resettled in the United States beginning in 2008 after previously being settled in United Nations (UN) refugee camps in Nepal. Due to the recency of their resettlement, there has been little research regarding diabetes in the Nepali-speaking Bhutanese American community. This study sought to identify the prevalence of diabetes in Nepali-speaking Bhutanese Americans living in the Greater Harrisburg Area and whether this community was at a higher risk of developing diabetes due to changes in diet and physical activity lifestyle behaviors. This study was conducted using an anonymous online survey. Anyone over the age of 18 and a self-identified member of the Nepali-speaking Bhutanese American community living in the Greater Harrisburg Area was included, regardless of their diabetes status. This study excluded individuals under the age of 18, those found outside the limits of the targeted region, and those who do not self-identify as members of the Nepali-speaking Bhutanese American community. Through this survey, data regarding demographics (age and gender), length of stay in the US, diabetes status (present or absent), consumption of rice (increased or decreased post-resettlement), and physical activity status (increased or decreased post-resettlement) were collected. The current prevalence of diabetes in this population was compared against the one reported by the CDC before migration and against the prevalence of diabetes in the general population of the United States of America (USA). The association between rice consumption, physical activity, and diabetes was analyzed using the odds ratio. The survey yielded responses from 81 participants. Results showed a 2.29 times higher prevalence of diabetes in the Bhutanese-speaking Nepali population of the Greater Harrisburg Area, Pennsylvania, compared to the general population of the USA. Results indicated a 37 times higher prevalence of diabetes after resettlement in the USA compared to the population's self-reported prevalence before the resettlement. The data showed that increased rice consumption or decreased physical activity alone did not significantly increase the risk of developing diabetes. However, the combination of decreased physical activity and increased rice consumption significantly increased the risk of diabetes, with an odds ratio of 5.94 (CI: 1.27 to 27.56, p-value: 0.01). The higher prevalence of diabetes in this community justifies diabetes education around causes, symptoms, treatments, and preventative healthcare methods. Greater awareness of the issue among the members of this community, as well as their healthcare providers, paves the way for future studies to identify all possible risk factors for diabetes in this community. Once risk factors are identified, early interventions and screening tools can be implemented to mitigate the onset of disease in this population in the future.
