Work-Related Disorders in Public Transportation Drivers and the Length of Exposure.

Background/Objectives: Public transportation drivers are exposed to a variety of occupational hazards. The scope of this study is to describe the most significant changes in symptoms and work-related disorders in the last decade in a sample of professional drivers from a large Romanian city, and, in particular, the cardio-metabolic and musculoskeletal impact. Methods: A retrospective study on 186 professional tram, trolley, and bus drivers from a total number of 344 employed by the company was conducted. The initial values (pre-employment) of the BMI, blood pressure, cholesterol, fasting glycemia, and musculoskeletal complaints were compared to the values of the last employment check-up. Results: After an average follow-up period of 11 years, BMI increased from 27.69 (SD = 4.68) to 30.06 (SD = 5.2) (p < 0.0001), cholesterol from 201.7 (SD = 39.87) to 212.62 (SD = 42.51), (p = 0.04). The number of cases of high blood pressure (25 to 56, p < 0.0001) and musculoskeletal complaints increased from 3 initial cases to 26 cases of neck pain (p = 0.07), from 2 to 49 cases of dorsal pain (p = 0.02), and from 18 to 59 cases of lumbar pain (p < 0.0001). High blood pressure and low back pain were significantly correlated with tenure, independent of other factors. Conclusions: As tenure is important in the development of cardiovascular and musculoskeletal diseases, specific interventions should be developed in the early stages of the drivers' career.
