Diabetes Mellitus in Drivers: A Cross-Sectional Study in Yazd, Iran, 2006 - 2009

Abstract

Background: Diabetes complications such as retinopathy and diabetic foot are more important in drivers compared to general population. Objectives: This study was designed to determine the prevalence of diagnosed and undiagnosed patients with diabetes mellitus and glucose intolerant, as well as the effects of follow up in the commercial drivers in Yazd province, Iran. Materials and Methods: During three consecutive years, levels of blood sugars were checked in 1137 registered drivers working on heavy motor vehicles such as trucks and buses. After 3 years, data was collected and analyzed by SPSS version 16. One sample K-S, Mauchly’s test, and if appropriate, variance analysis test were performed to compare FBS levels differences between the three occasions. Results: The mean age of participants was 47.7 ± 28.7 (19 - 56) years old, and they were working on heavy vehicles for 15.3 ± 9.3 (26 - 47) years. The prevalence of diagnosed diabetes was 3.3% (n = 38), but the prevalence of FBS > 127 was 6.3%, and that of impaired glucose test was 4.9%. There was a significant reduction in the blood glucose levels from the first to the third occasions in drivers with type 2 diabetes. Conclusions: The prevalence of diabetes is considerable in drivers and is poorly controlled. Educations during the annual check-ups are helpful in reducing glucose levels and further complications.
