The demand-control-support "job strain" model is frequently used in occupational health research. We sought to explore the relationship between job strain and back pain.
One thousand two hundred and ninety-eight collaborators of a Swiss teaching hospital responded to a cross-sectional questionnaire survey that measured job strain, the occurrence of back pain as well as the characteristics and consequences of this pain.
Job strain computed with both psychological and physical demands was strongly and significantly associated with various measures of back pain. These associations displayed a dose-response pattern, and remained strong even after adjustment for job characteristics and professional categories. In contrast, separate dimensions of job strain (except physical demands) and job strain computed with only psychological demands did not remain significantly associated with back pain after adjustment for other variables.
Our results support the findings linking back pain to job strain. Moreover, the relationship between back pain and job strain is much stronger if job strain includes both psychological and physical demands. Results of this study suggest that workplace interventions that aim to reduce job strain may help prevent back pain and may alleviate the personal, social, and economic burden attributable to back pain.
需求-控制-支持的“工作压力”模型在职业健康研究中经常使用。我们试图探讨工作压力与背痛之间的关系。
瑞士一所教学医院的 1298 名合作者对一项横断面问卷调查做出了回应，该问卷测量了工作压力、背痛的发生情况以及这种疼痛的特征和后果。
用心理和体力需求计算出的工作压力与各种背痛测量指标密切相关且具有统计学意义。这些关联呈剂量反应模式，即使在调整了工作特征和职业类别后，这些关联仍然很强。相比之下，工作压力的单独维度（体力需求除外）和仅用心理需求计算出的工作压力在调整其他变量后与背痛不再有显著关联。
我们的结果支持将背痛与工作压力联系起来的研究结果。此外，如果工作压力包括心理和体力需求，背痛与工作压力之间的关系更强。本研究的结果表明，旨在降低工作压力的工作场所干预措施可能有助于预防背痛，并减轻与背痛相关的个人、社会和经济负担。
