Quality of life (QoL) indicates individual's perception of the physical, psychological and social aspects of health. The association between QoL and all stressful life events' dimensions has not been investigated among industrial employees.
The present study aimed to investigate the association between stressful life events and QoL in a large sample of Iranian industrial employees.
In a cross-sectional study, 3063 manufacturing employees in Isfahan, Iran, were recruited. QoL was measured with the Euro-QoL five dimension questionnaire (EQ-5D). Stressful life events were assessed by an Iranian validated stressful life event questionnaire (SLE). Multilevel latent class regression was employed for classifying participants based on QoL and for determining its association with stressful life events.
Two classes of employees, ie, low (comprised 20% of participants) and high QoL (80%), were identified. From 11 dimensions of stressful life events two major domains, socioeconomic and personal stressor profiles, were identified. Multilevel latent class regression results showed that the higher scores of social (OR: 1.14, 95%CI: 1.12-1.16) and personal (OR: 2.36, 95%CI: 1.87- 2.98) stressor domains were significantly associated with increased risk of being in the poor QoL class. Among personal and socioeconomic stressors, health concerns and daily life dimensions had higher significant association with poor QoL.
Results of our study indicated that life stressors have negative impacts on QoL of employees. Personal stressors showed higher negative impact than socioeconomic on QoL. Managing the stressors can play an effective role in improving the QoL of employees, their physical and mental health, and indirectly enhances the organizational performance and job productivity.
生活质量（QoL）反映了个体对健康的身体、心理和社会方面的认知。尚未在产业员工中研究生活质量与所有应激性生活事件维度之间的关联。
本研究旨在调查大量伊朗产业员工中应激性生活事件与生活质量之间的关联。
在一项横断面研究中，招募了伊朗伊斯法罕的3063名制造业员工。采用欧洲生活质量五维度问卷（EQ-5D）测量生活质量。通过一份经伊朗验证的应激性生活事件问卷（SLE）评估应激性生活事件。采用多水平潜在类别回归根据生活质量对参与者进行分类，并确定其与应激性生活事件的关联。
识别出两类员工，即低生活质量组（占参与者的20%）和高生活质量组（80%）。从应激性生活事件的11个维度中识别出两个主要领域，即社会经济和个人应激源概况。多水平潜在类别回归结果显示，社会应激源领域得分较高（比值比：1.14，95%置信区间：1.12 - 1.16）和个人应激源领域得分较高（比值比：2.36，95%置信区间：1.87 - 2.98）与处于低生活质量组的风险增加显著相关。在个人和社会经济应激源中，健康问题和日常生活维度与低生活质量的关联更为显著。
我们的研究结果表明，生活应激源对员工的生活质量有负面影响。个人应激源对生活质量的负面影响高于社会经济应激源。管理应激源可以在改善员工的生活质量、身心健康方面发挥有效作用，并间接提高组织绩效和工作效率。
