Objectives: To study the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) and their risk factors in Jordan.
Design: A cross-sectional study in four Jordanian communities was conducted: Sarih in the north, Sikhra in the middle of the country, Mazar in the south and Subha-Subheih in the east. Within each community, a systematic sample of households was selected. All subjects > or =25 years of age within the selected households were invited to participate in the study. A total of 2836 subjects were actually included in the study with an overall response rate of 70.5%(45% in males and 86% in females). World Health Organization criteria were adopted for the diagnosis of DM (fasting plasma glucose > or =7.8 mmol L(-1) or plasma glucose of > or =11.1 mmol L(-1), 2 h after an oral anhydrous glucose load of 75 g) and IGT (fasting plasma glucose <7.8 mmol L(-1)and plasma glucose between 7.8 mmol L(-1) and 11.1 mmol L(-1), 2 h after an oral glucose load of 75 g).
Results: The overall prevalence of DM was 13.4%: 14.9% in males and 12.5% in females. IGT was found in 9.8% of the study population: 9.0% in males and 10.3%, in females. Factors independently related to DM using stepwise logistic regression analysis were sex, age, family history of DM, hypertension, hypercholesterolaemia (HC), and hypertriglyceridaemia (HTG).
Conclusion: Diabetes mellitus and IGT are common among adult Jordanians. Considering the high prevalence of this sickness makes it imperative to formulate a national plan to face this disease and its complications.
