Job stress dimensions and their relationship to musculoskeletal disorders in Iranian nurses

Abstract

Background: There is little data available on job stress dimensions and their relationship to musculoskeletal disorders (MSDs) among Iranian nurses.

Objectives: The objectives of this study were to investigate job stress dimensions and examine their relationship to MSDs among nurses of Shiraz University of Medical Sciences (SUMS) hospitals.

Methods: In this cross-sectional study, 385~randomly selected nurses of SUMS participated. The Persian version of Job Content Questionnaire (P-JCQ) and Nordic MSDs questionnaire were used for data collection. Descriptive statistics and Mann-Whitney U test were applied for data analysis.

Results: Decision latitude and social support dimensions had low levels, but psychological and physical job demands as well as job insecurity dimensions had high levels among the nurses. 89.9% of the subjects experienced some form of MSDs during the last 12 months. Lower back symptoms were the most prevalent problem reported (61.8%). Physical isometric loads was the only sub-scale that had significant relationship with MSDs.

Conclusions: In the majority of cases, subjects were exposed to high levels of job stress. MSDs prevalence was high. Based on the results, any interventional program for MSDs prevention should focus on reducing physical and psychological job demands as well as increasing decision latitudes.
