Abstract: Background: Work-related musculoskeletal problems (WMSP) are amongst the most frequent and costly health problems experienced by the working population. Adverse physical and psychosocial work factors contribute to the development of WMSP. Workplace interventions targeting these factors may help reduce their prevalence and thus reduce WMSP. The Québec Healthy Enterprise Standard (QHES) targets four intervention areas, two of which aim to reduce adverse physical and psychosocial work factors. Few interventions targeting both these factors on WMSP outcomes have yet been evaluated and none in the context of a standard. Objectives: 1) Measure pre-post changes in the prevalence of adverse physical and psychosocial work factors and WMSP; 2) Examine if the prevalence of these adverse work factors and that of WMSP is lower amongst participants exposed to the QHES areas of interest; 3) Measure cross-sectional associations postulated by the theoretical framework guiding this project. Methods: This was a mixed-methods study with before-after and cross-sectional designs. Employees of 10 Québec organizations completed a questionnaire before (T1; n=2849) and 24-38 months following (T2; n=2560) QHES implementation. Participating organizations voluntarily adopted the standard and were responsible for implementing interventions. Physical work factors were measured with five items. Psychosocial work factors were assessed using items from validated models. WMSP were measured with four items adapted from the Nordic Questionnaire. Results: The prevalence of one adverse physical and three adverse psychosocial work factors was lower amongst participants who reported being exposed to interventions in each QHES area of interest. No difference in the prevalence of WMSP was observed amongst participants who reported being exposed to these two areas simultaneously. The intensity of implemented interventions could partly explain these results. Strong cross-sectional associations supported the theoretical framework used. Further research is warranted to determine the effectiveness of interventions targeting both adverse physical and psychosocial work factors in preventing WMSP.
