Abstract
BACKGROUND: Bus and truck drivers are apparently more involved in metabolic syndrome and its complications due to their working conditions. The related impacts are not only harmful for driver's health, but also may endanger others. The present research was carried out to determine the prevalence of metabolic syndrome among bus and truck drivers in Kashan, a city in Iran. MATERIALS: In 2007, 429 bus and truck male drivers were enrolled to this cross sectional study to examine the metabolic syndrome using ATPIII criteria. Statistical tests including Chi-Square test, T-student test and Pearson's correlation coefficient were used to analyze the data. RESULTS: Prevalence of metabolic syndrome in subjects was 35.9%. Hypertension and diabetes were seen in 42.9% and 7% of the drivers respectively. Body mass index (BMI) in 41% of the drivers within the range of 25-30 was considered overweight and 23% of them were found to be obese. High triglyceride (53.4%) and low HDL-C levels (48.7%) were more common than other components of metabolic syndrome. A significant positive correlation was seen between BMI, diabetes, high blood pressure and metabolic syndrome (p < 0.001); but there was no positive correlation between metabolic syndrome and smoking (p < 0.06). CONCLUSION: High prevalence of metabolic syndrome and other relevant risk factors for coronary heart diseases (CHD) were detected among the drivers. Based on these findings, it is recommended to consider training programs, establish pertinent health regulations, and focus on the metabolic syndrome complications in high risk group to improve and maintain their quality of life and to promote their public health.
