An increase in prevalence of diabetes mellitus in Jordan over 10 years

Abstract Objective This study aimed to determine the prevalence of type 2 diabetes mellitus (DM) and impaired fasting glycemia (IFG), identify their associated factors, determine how the prevalence of type 2 DM has changed over 10 years, and assess the awareness and state of control of diabetes in Jordan. Methods Data were analyzed from a cross-sectional study that included a random sample of 1121 Jordanians aged 25 years and above. A subject was deemed affected by DM if this diagnosis was known to the patient or if his or her condition complies with the American Diabetes Association definition. IFG was defined as a fasting serum glucose level of ≥6.1 mmol/l (110 mg/dl) but 7.5% was defined as “unsatisfactory” metabolic control. Results The age-standardized prevalence of diabetes and IFG was 17.1% and 7.8%, respectively, with no significant differences between women and men. Of the 195 diabetic subjects, 146 (74.9%) had been previously diagnosed. More than half (54%) of those previously diagnosed were found to be with unsatisfactory glycemic control. Compared to the 1994 survey, there was a significant increase in the prevalence of diabetes by 31.5%. Increase in age, increase in body mass index, and having a family history of diabetes were associated with increased odds of diabetes and IFG. While the level of education had no effect on IFG, higher level of education was associated with a decrease in the odds of having diabetes. Conlusion The prevalence of type 2 diabetes and IFG is high in Jordan and is increasing. More than half of the patients with diabetes have unsatisfactory control. Therefore, they are likely to benefit from programs aimed at encouraging behaviors toward achieving optimum weight as well as physical activity behaviors. Physicians caring for patients with diabetes may need to adopt a more vigorous approach for diabetes control.
