Glucose intolerance and associated factors in the multi-ethnic population of the United Arab Emirates: results of a national survey
Introduction
At the global level, the modern epidemic of type 2 diabetes and its association with the rising prevalence of obesity are well established. Data from the World Health Organization predict doubling in the number of persons with diabetes in the world, from 150 million to 300 million, between the years 2000 and 2025 [1]. However, such estimates rely on a number of extrapolations and there are still many countries in which the prevalence of diabetes remains unknown.
The prevalence of diabetes and its contribution to disease burden in the United Arab Emirates (UAE) has not been established previously. However, clinical observation suggests diabetes and associated non-communicable diseases (NCDs) now have a major impact on the public health of both the indigenous and expatriate communities.
In this article, the results of the Emirates National Diabetes and Coronary Artery Disease Risk Factor Study (ENDCAD) are reported, with respect to diabetes and impaired fasting glycaemia (IFG) and obesity and hypertension. Associations with ethnicity and co-morbidities are also examined.

Background
The UAE is a federation of seven Emirates, situated on the shores of the Arabian Gulf and the Gulf of Oman and sharing land borders with Oman and Saudi Arabia. UAE has a total area of approximately 83,000 km2. With the exception of a few fertile oases, the dominant feature of the landscape is the flat coastal plain, which merges with rolling sand dunes and vast desert hinterland of Arabia.
According to the 1995 census [2], the total population of the UAE was 2.7 million, of whom 20% were UAE
Results
A total of 6564 subjects were invited to attend, of whom 5844 completed the examination. Overall response rate was 89%, which was slightly better among non-citizens than UAE nationals. The study involved 2499 men (43%) and 3345 women (57%). UAE citizens comprised 40% of the total study population. Women outnumbered men by a factor of 2 among UAE citizens. However, both genders were equally represented among expatriates. The large majority of both men and women were aged 25–54 years (Table 1).
Discussion
With a crude prevalence of 20%, diabetes can be considered a serious public health problem in the adult population of the UAE. Prevalence was highest in UAE citizens, one-quarter of all those examined being diagnosed diabetic. Comparable studies in the Gulf region include a prevalence of 12% and 14% in urban men and women, and 7% and 8% in rural men and women, in Saudi Arabia in 1995 [7]. Age-specific prevalence in Bahrain, ranged from 23% in men aged 40–49 years to 37% in women aged 60–69
