Abstract

Aims: To determine the prevalence of type 2 diabetes mellitus in a sample of the adult population of Alexandria, Egypt, and to delineate the epidemiologic profile of the disease in this community.

Methods: This cross-sectional study was conducted on a representative sample of the population. Participants provided demographic data, their medical history, and blood samples for measurement of plasma glucose (fasting and after oral glucose load) and underwent a detailed physical examination.

Results: Of 10,640 eligible subjects, 9657 (90.8%) aged 18-90 years agreed to participate (3795 men, 5862 women). We found an age-adjusted prevalence of diabetes of 16.8% (men, 12.7%; women 19.1%); of prediabetes, 14.6% (men, 13.5%; women, 15.2%), and of newly diagnosed diabetes, 5.5% (men, 3.3%; women, 6.6%). Diabetes was most common in people older than 50 years; prediabetes was most common in 30-39-year-old men and in women younger than 20. In logistic regression analysis, factors independently associated with prediabetes were a history of dyslipidaemia, urban residence, and widowhood. Independent associated factors for diabetes were a high waist-to-hip ratio, family history of diabetes, being divorced, history of dyslipidaemia, peripheral arterial disease or hypertension, low education level, and being not working.

Conclusions: We found a high prevalence of diabetes and prediabetes in Alexandria, particularly in the middle-aged population. Given globally increasing life expectancies, the number of individuals with diabetes could become particularly challenging to the Egyptian healthcare system. Comprehensive national preventive measures are urgently needed.
