Rol van fysieke belasting, psychosociale en psychologische factoren bij kort- en landurende lage rugpijn en ziekteverzuim in een werknemerspopulatie.

Abstract

This cross-sectional study examines a number of work related physical, psychosocial and psychological correlates of temporary and long-lasting lower back pain and sick leave among 712 employees of a Belgian metallurgical plant. Associations have been studied through multiple logistic regressions, while controlling for relevant confounders. The main conclusion is that physical strain is related to contemporary lower back pain, and that physical strain and psychosocial factors such as job demands, power of decision and social support ar associated with long-lasting lower back pain. A remarkable finding is that a lack of power of decision and a high level of fear of movement are significantly related to sick leave. Finally, the results show that the variables psychological job demands and power of decision clearly interact in their effect on sick leave.
