Prevalence of diabetes and its correlates among Iranian adults: Results of the first phase of Shahedieh cohort study.

Background and Aims: The diabetes is one of the most common noncommunicable diseases, the prevalence of which is increasing worldwide. This study aimed to determine the prevalence, and correlates the factors of diabetes in the setting of Shahedieh cohort study in Yazd, Iran. Method: The present study is a cross-sectional study conducted on the data of the initial stage of Shahdieh Yazd cohort. This study examined the data of 9747 participants aged from 30 to 73 years. The data included demographic, clinical, and blood test variables. Multivariable logistic regression was used to calculate the adjusted odds ratio (OR), and the risk factors of diabetes were studied. Meanwhile, population attributable risks for diabetes were estimated, and reported. Results: The prevalence of diabetes was 17.9% (CI95%: 17.1-18.9); 20.5% in women, and 15.4% in men. Based on the results of multivariable logistic regression showed female sex (OR = 1.4, CI95%: 1.24-1.58), waist-hip ratio (OR = 1.4, CI95%: 1.24-1.58), high blood pressure (OR = 2.1, CI95%: 1.84-2.4), cardiovascular diseases (CVD) (OR = 1.52, CI95%: 1.28-1.82), stroke (OR = 1.91, CI95%: 1.24-2.94), age (OR = 1.81, CI95%: 1.67-1.96), hypercholesterolemia (OR = 1.79, CI95% triglyceride: 1.59-2.02), and low-density lipoprotein (LDL) (OR = 1.45, CI95%: 1.4-1.51), as risk factors for diabetes. Among the modifiable risk factors, high blood pressure(52.38%), waist-to-hip ratio (48.19%), the history of stroke (47.64%), hypercholesterolemia (44.13%), history of CVD (34.21%), and LDL ≥ 130 (31.03%) had the greatest population-attributable, respectively. Conclusion: The results showed that some of the main determinants of diabetes are the modifiable risk factors. Therefore, implementing early detection, and screening programs for people at risk and preventive measures, such as lifestyle modification programs, and control of risk factors can prevent this disease.
