上海某互联网企业程序员睡眠质量在职业紧张和健康生产力损失间的中介效应

Mediating effect of sleep quality on occupational stress and health-related productivity loss in programmers of an Internet enterprise in Shanghai

【目的】探索互联网企业程序员职业紧张对睡眠质量和健康生产力损失的影响,以及睡眠质量在职业紧张和健康生产力损失之间的中介效应,为减少企业健康生产力损失提供干预策略。【方法】2021年4月,对上海某互联网企业程序员开展职业紧张、睡眠质量和健康生产力水平问卷调查,包括工作内容问卷、匹兹堡睡眠质量指数问卷、工作生产力和活动受损问卷,有效回收问卷251份(89.6%)。应用多元回归分析探讨互联网企业程序员职业紧张和睡眠质量对健康生产力损失的影响,用中介效应分析检验睡眠质量在职业紧张和健康生产力损失之间的中介作用。【结果】职业紧张和睡眠质量问题是健康生产力损失的重要影响因子,呈显著正相关(P<0.01);职业紧张与睡眠质量问题呈显著正相关(P<0.01);睡眠质量问题在职业紧张与健康生产力损失中起正向的中介作用,其中介效应在职业紧张与工作效率影响、无效工作时间、因病缺勤时间、总健康生产力损失的效应中分别占11.97%、10.14%、34.60%和12.52%。【结论】互联网企业程序员职业紧张、睡眠质量和健康生产力三者之间密切相关,睡眠质量在职业紧张和健康生产力之间起到部分中介作用。提示可设计系列睡眠提升计划来减少职业紧张对健康生产力损失的影响,提高互联网企业的健康生产力水平。

[Objective]To explore the effect of occupational stress on sleep quality and health-related productivity loss,and the mediating effect of sleep quality on occupational stress and health-related productivity loss in programmers of an Internet enterprise,in order to suggest intervention strategies for reducing health-related productivity loss.[Methods]In April 2021,a cross-sectional survey on occupational stress,sleep quality and health-related productivity was carried out among programmers in an Internet enterprise in Shanghai,with a work content questionnaire,a Pittsburgh sleep quality index questionnaire,and a work productivity and impaired activity questionnaire.Complete questionnaires were obtained from 251 individuals(response rate:89.6%).Multiple regression analysis was used to explore the effects of occupational stress and sleep quality on health-related productivity loss of programmers in the Internet enterprise,and the mediating effect of sleep quality on occupational stress and health-related productivity loss was tested by mediating effect analysis.[Results]Occupational stress and sleep quality were important influencing factors of health-related productivity loss,a significant positive correlation was observed(P<0.01),and occupational stress was positively correlated with sleep quality problems(P<0.01).Sleep quality had a positive mediating effect on occupational stress and health-related productivity loss.The mediating effect on the occupational stress and reduced work efficiency,invalid working hours,sickness absenteeism,and total health-related productivity loss was 11.97%,10.14%,34.60%and 12.52%,respectively.[Conclusion]There is a close correlation between occupational stress,sleep quality and health-related productivity of programmers in the Internet enterprise,and sleep quality plays a partial mediating role between occupational stress and health-related productivity.A series of sleep quality improvement plans should be designed to reduce the impact of occupational stress on the loss of health-related productivity,and to improve health-related productivity in Internet enterprises.
