Screening strategy for type 2 diabetes in the United Arab Emirates

The prevalence of type 2 diabetes mellitus (DM) among Emirati nationals is one of the highest in the world. The recently released United Arab Emirates National DM guidelines call for screening all adults aged 30 years and more. The authors explored the need for such a modification of current American Diabetes Association (ADA) guidelines. They also considered the prevalence rates for undiagnosed DM based on oral glucose tolerance test (OGTT) versus glycohemoglobin (HbA1c) ? 6.5% in a population-based sample of 296 adult Emirati participants. In the low-risk ADA category, defined by age <45 years and BMI <25, only 1 of 68 (1.5%) participants was diagnosed with DM. The overall rate of DM based on HbA1c was lower than that based on OGTT (10.1% versus 14.2%P < .05). The authors conclude that the ADA guidelines are adequate for screening in this high-risk population. They also find high discordance between HbA1c and OGTT
