Abstract
This study investigated the psychosocial and physiological environments and their possible relationships to musculoskeletal symptoms (MSS) and headaches at a high-tech telecommunications company. Two departments (1 16 subjects) responded to a questionnaire focusing on psychosocial and physical environment socio-economic status, health and well-being. Blood samples were analysed for testosterone, cortisol, and prolactin. A significant correlation was found between MSS and low skills utilization as well as poor balance between job autonomy and workload. The results also revealed correlations between some other occupational psychosocial factors and MSS and headaches, respectively. A significant correlation was also found between intensity of MSS and decreased testosterone levels. It is concluded that at least part of musculoskeletal symptoms and headaches found in high-tech environments might be mediated via neuroendocrine mechanisms. These results are based on a cross-sectional study they should therefore be repeated-preferably using a longitudinal and interventional approach.
