This study aims to explore if objectively and subjectively measured sleep parameters are associated with physical and mental health-related quality of life in a multiethnic working population in Singapore. We performed a cross-sectional analysis with data from 329 full-time employees enrolled in a workplace cohort study in Singapore. The Short-Form 36v2 (SF-36v2) survey was used to assess health-related quality of life, in terms of physical and mental health. Subjective and objective sleep parameters were measured using the Pittsburgh Sleep Quality Index and wrist actigraphy, respectively. Generalized linear modeling was performed to examine the association between sleep parameters and health-related quality of life. After adjusting for confounders, subjectively measured sleep disturbances were associated with a lower physical health-related quality of life, whereas higher, objectively measured sleep efficiency was associated with greater physical health-related quality of life. Subjectively measured daytime dysfunction was associated with impaired mental health-related quality of life. Using both objective and subjective measurements of sleep, the current study suggests that there is an association between sleep and health-related quality of life. Workplace health-promotion planners in Singapore should consider programmes that educate workers on better sleep hygiene practices in an effort to improve sleep and health-related quality of life.
本研究旨在探讨在新加坡的多民族工作人群中，客观和主观测量的睡眠参数与身心健康相关的生活质量是否存在关联。我们对新加坡一个工作场所队列研究中的 329 名全职员工进行了横断面分析。使用健康相关生活质量的短式 36 项健康调查（SF-36v2）问卷评估身心健康。分别使用匹兹堡睡眠质量指数和腕动仪测量主观和客观的睡眠参数。采用广义线性模型检验睡眠参数与健康相关生活质量之间的关联。在调整混杂因素后，主观测量的睡眠障碍与较低的身心健康相关生活质量相关，而客观测量的较高睡眠效率与较好的身心健康相关生活质量相关。主观测量的日间功能障碍与心理健康相关生活质量受损相关。本研究使用客观和主观的睡眠测量，表明睡眠与健康相关的生活质量之间存在关联。新加坡的工作场所健康促进规划者应考虑开展教育工人改善睡眠卫生习惯的计划，以改善睡眠和健康相关的生活质量。
