Perceived work-related stress and pain prevalence: results from the Italian CUPID study
本研究基于意大利护士调查数据，发现工作相关压力和躯体化倾向是肌肉骨骼疼痛的重要风险因素，即使在没有重体力劳动的人群中也成立。
<h3>Objectives</h3> To assess the importance of work-related stress among recognised risk factors in causing musculoskeletal disorders (MSDs). <h3>Methods</h3> The CUPID standardised questionnaire was administered to 518 nurses employed in a large University Hospital in Varese (Italy) to collect MSK disorders in last month and related work-absence. We also collected self-perceived work-related stress through the two most internationally validate tools: the Job-Content and the Effort-Reward Imbalance questionnaires (ERI-Q and JC-Q respectively). Somatising tendency and Overcomittment were also investigated. Multivariate logistic regression, stratified by physical workload, was used to assess the association between outcomes and risk factors adjusted for age and sex. <h3>Results</h3> Of the 410 collected questionnaire (participation rate=79%), low-back pain was reported by 50%, neck pain by 47% and shoulder pain by 33%. The two stress questionnaires showed high inter-correlation, with ERI resulting with a higher internal consistency. Considering pain prevalence, after controlling for age and sex, ERI-Q resulted associated to low-back and neck in the group who declared no exposure to heavy lifting (OR=1.48 IC 95%:1.11–1.99 and OR=1.22 IC 95%:1.04–1.44 respectively). JC-Q was associated only to a higher prevalence of shoulder pain in both groups (OR=1.91 IC 95%=1.02–3.59 among not exposed and OR=3.16 IC 95%=1.24–8.06 among exposed). Somatising tendency was associated to pain prevalence in all investigated districts, with higher ORs seen among patients not exposed to physical workload. <h3>Conclusions</h3> Psychosocial factors such as perceived stress and somatising tendency resulted to be an important risk factor for MSD, besides to the already established ones. Results of 1-year follow-up will be also presented.
