The effect of diabetes and the diabetogenic TBC1D4 p.Arg684ter variant on kidney function in Inuit in Greenland

Prevalence of cardiovascular and other selected diseases among Greenlanders with and without type 2 diabetes

This study aims to estimate the prevalence of cardiovascular disease, kidney disease, and other selected diseases including hypertension, atrial fibrillation, asthma, chronic obstructive lung disease, osteoarthritis, osteoporosis, psoriasis and depression among Greenlanders living in Nuuk with and without type 2 diabetes (T2D). The study was designed as a cross-sectional case-control study based on data from the electronic medical record (EMR) in Greenland. Persons with a registered T2D diagnosis in EMR and residence in Nuuk (N = 435) were included. The prevalence of cardiovascular disease was 17.9% among persons with T2D and significantly higher compared to the control group (10.1%). In addition, our results showed a significantly higher prevalence of ischaemic heart disease, hypertension, heart failure, atrial fibrillation, osteoarthritis and psoriasis among persons with T2D compared to the control group.Our study found a higher prevalence in five out of 10 selected diseases in regularly followed persons with T2D in Nuuk compared to unselected controls. This enlightens the importance of a broad multifaceted approach in combination of changing primary health care to focus on early detection of controllable risk factors and chronic conditions care in Artic Greenland.

Burden of selected chronic non-communicable diseases in a primary healthcare setting in Nuuk, Greenland, compared to a Danish suburb

INTRODUCTION

Noncommunicable diseases (NCDs) constitute a massive global burden and are the leading cause of death and disability worldwide. In Greenland, the prevalence of NCDs has historically been low. However, during the past approximately 70 years, life circumstances have changed dramatically resulting in increased life expectancy. Today, the proportion of inhabitants in Greenland ≥65 years has nearly tripled since the 1980s, and the prevalence of obesity and diabetes has increased rapidly within the past decades. The aim of this study was to describe the burden of selected NCDs in a primary care setting in Nuuk and compare it to a modern westernized suburban general practice in Denmark.

METHODS

The study was performed as a cross sectional register-based study using data extracted from the electronic medical records (EMR) based on diagnosis codes from inhabitants living in Nuuk, Greenland, and a suburb in Denmark. Estimates of prevalence were age-standardized to the WHO world standard population.

RESULTS

In both Nuuk and the Danish suburb, the highest prevalence was observed for hypertension (13.2% for both populations), followed by asthma (4.4 and 9.5%, respectively) and diabetes (4.3 and 2.9%, respectively). The age-standardized prevalences of diabetes, COPD, atrial fibrillation, and heart failure, were significantly higher in Nuuk, while seven NCDs including asthma, ischemic heart disease, arthritis urica, psoriasis, hyperthyreosis, hypothyreosis and osteoporosis were significantly higher in the Danish suburb.

CONCLUSION

In contrast to the disease pattern observed in Greenland in the last century, the prevalence of diagnosed NCDs in Nuuk is no longer rare. Thus, the overall prevalence of NCDs in the population of Nuuk is now comparable to or even higher than in the suburb in Denmark. This calls for increased focus on all NCDs in the primary healthcare system in Greenland and adaption of the primary healthcare services to a changed disease spectrum.
