RESUMO
AIMS: To determine the prevalence of diabetes and impaired fasting glycaemia (IFG) and associated conditions such as obesity and hypertension, in the multi-ethnic, adult population of the United Arab Emirates in 1999-2000. METHODS: A stratified, multistage, random sample was selected. Diagnosis was based on the latest recommendations of a WHO Expert Group. RESULTS: The overall response rate was 89%. Crude prevalence of diabetes was 20%. It was higher in UAE citizens (25%) than in expatriates (13-19% depending on country of origin). Prevalence of diabetes rose with age to a maximum of 40% after the age of 55 years. Prevalence of impaired fasting glycaemia was 5% in men and 7% in women. Forty-one percent of subjects with diabetes were undiagnosed prior to the survey. Of the previously diagnosed subjects with diabetes, 59% were taking oral hypoglycaemic agents, 8% used insulin and 17% relied on diet alone. Obesity was common in all ethnic groups. Approximately three-quarters of all subjects were either obese (BMI> or =30) or overweight (BMI 25-29). Presence of diabetes was associated with increasing waist-hip ratio (WHR), age and with systolic blood pressure and ethnicity. Co-morbidity with glucose intolerance occurred with obesity in 8% and with hypertension in 5%. Three-quarters of all subjects had one or more of these conditions. CONCLUSIONS: Diabetes, obesity and hypertension are extremely prevalent in the adult population of the UAE. Prompt action is required to avert a major public health crisis due to the long-term complications of diabetes in the near future.
