STUDY DESIGN: Back and @entity4048 was studied cross-sectionally in 1,449 urban transit drivers by linking medical data, self-reported ergonomic factors, and company records on job history. OBJECTIVES: The goal was to examine the relation between physical workload, ergonomic factors, and the @entity615 . SUMMARY OF BACKGROUND DATA: Researchers, to date, have not found an independent effect of ergonomic factors on back and @entity4048 while accounting for the effects of past and current physical workload. METHODS: Self-reported ergonomic factors, vehicle type, physical workload (measured as duration of driving), height, weight, age, and gender were analyzed in @entity615 , using multivariable logistic regression models. RESULTS: Physical workload showed a positive dose-response relation with back and @entity4048 after controlling for vehicle type, height, weight, age, and gender. The odds ratio for 10 years of driving was 3.43. Additional adjustment for ergonomic factors decreased this odds ratio to 2.55. Six out of seven ergonomic factors were significantly related to the @entity615 after adjustment for age, gender, height, weight, and physical workload. Problems with adjusting the seat had the largest effect (odds ratio = 3.52). @entity1 had back and @entity4048 twice as frequently as @entity1 . CONCLUSION: The results support the hypothesis of a causal role of physical workload for the @entity615 . Ergonomic factors partially mediated the risk of back and @entity4048 associated with driving, suggesting a potential for prevention of back and @entity4048 by ergonomic redesign of transit vehicles. @entity615 for female drivers were not explained by anthropometric and ergonomic factors.
