Abstract
Background: Heavy vehicle drivers are at risk of musculoskeletal disorders due to risk factors that are present in their job. The aim of this study was to investigate the prevalence and risk factors of musculoskeletal disorders in bus and truck drivers. Methods: This cross-sectional study was carried out on 275 bus and 272 truck drivers using random sampling method. Nordic Musculoskeletal Questionnaire (NMQ) was used to assess the prevalence of musculoskeletal disorders. All analysis was performed by R software. Results: The mean age of bus and truck drivers was 42.74 and 39.76 years, respectively. In total, 26.9% of bus drivers and 31.6% of truck drivers reported pain in one of their nine body parts at least once during the previous year. The waist and knee with a prevalence of over 17% had the highest frequency. The results showed high frequency of exposure to vibration and smoking in the both groups. About 61% of drivers in both groups reported lack of job satisfaction. Conclusion: The prevalence of musculoskeletal disorders, especially low back pain in drivers was high. It seems that the development of an appropriate program for improving occupational health in drivers especially ergonomic interventions is necessary.

Abstract
Background: Undoubtedly, lack of good quality sleep is a major problem for students, affecting their educational success causing them academic failure. Therefore, this study is carried out aiming to determine sleep quality and its relation with educational status of Iran University of Medical Sciences students. Methods: This study is a sectional-analytic one performed on dormitory and non-dormitory students of Iran University of Medical Sciences. The criteria of entering the study include being student for at least one year, non-affliction to special diseases and not using drugs and tobacco. People were selected in proportional stratified sampling method after determining the sample volume (400), and Petersburg sleep quality questionnaires were distributed among them. After completion of the questionnaires, their data were extracted and introduced into SPSS version 21. The data obtained via T statistical tests for which Pearson correlation was analyzed were independent. Results: The sleep quality mark was higher than 5 for majority of the students including the dormitory and non-dormitory ones; expressing weak sleep quality. Sleep quality was 7.36 for dormitory students and 7.97 for non-dormitory ones; expressing significant statistical difference (p=0.018). The results suggest that educational status of non-dormitory students (0.22) is better than the dormitory ones (-1.23), and the difference is statistically significant (p=0.000). moreover, the results suggest that there is no relation between good sleep quality and educational status of the students (p=0.232). Conclusion: The study results suggest that sleep quality is not related to educational status. Considering that educational status is a complex matter and is affected by multiple factors including: intelligence, motivation and hard work, sleep quality plays less significant role regarding educational status.
