Studies of health-related quality of life among workers have generated varying results. The purpose of this study was to conduct a systematic review to synthesize the scores of health-related quality of life measured by the World Health Organization Quality of Life questionnaire among Chinese workers and compare the results across gender, age, occupation and region.
Six databases including China National Knowledge Infrastructure, WanFang Data, China Science and Technology Journal Database, PubMed, Web of science and Scopus were searched for relevant publications in both English and Chinese from their inception to February 2021. Inclusion and exclusion criteria were established, and study and participant characters as well as health-related quality of life scores were extracted from included publications. Study quality was assessed by using the Crombie tool. The meta-analysis including individual publications used random-effects models. Subgroups analyses by gender, age, occupation and region were also conducted to explore the source of heterogeneity.
One hundred thirty-nine out of 1437 potential publications were included. The pooled mean scores of health-related quality of life were 14.1 for the physical domain (95%CI: 13.9-14.3), 13.7 for the psychological domain (95%CI: 13.5-13.8), 14.0 for the social relationship domain (95%CI: 13.8-14.2), 12.3 for the environment domain (95%CI: 12.1-12.5). No significant statistical difference was found between the different subgroups. Publication bias was present in the independence domain and the pooled scores were corrected to 15.0 (95%CI: 14.6-15.5) using the trim and fill method. Sensitivity analysis suggested that the results of the meta-analysis were stable. Region might be a source of heterogeneity. Workers in northeast China reported higher scores in the social relationship domain, and those in the central region reported lower scores in the environmental domain.
Chinese workers reported lower scores in four health-related quality of life domains than the general population. Region might be a potential influencing factor for workers' scores different, which needs further study. The pooled scores can served as benchmarks for workplace health promotion programes in Chinese workers and global occupational health studies.
针对工人健康相关生活质量的研究结果各异。本研究旨在进行系统综述，综合中国工人的生活质量问卷（世界卫生组织）测量的健康相关生活质量得分，并比较不同性别、年龄、职业和地区的结果。
检索中国知网、万方数据、中国科技期刊数据库、PubMed、Web of Science 和 Scopus 等 6 个数据库，检索英文和中文从建库到 2021 年 2 月的相关文献。建立纳入和排除标准，从纳入文献中提取研究和参与者特征以及健康相关生活质量评分。使用 Crombie 工具评估研究质量。使用个体出版物的荟萃分析采用随机效应模型。还进行了按性别、年龄、职业和地区的亚组分析，以探讨异质性的来源。
从 1437 篇潜在文献中筛选出 139 篇。健康相关生活质量的综合平均得分分别为：生理领域 14.1（95%CI：13.9-14.3），心理领域 13.7（95%CI：13.5-13.8），社会关系领域 14.0（95%CI：13.8-14.2），环境领域 12.3（95%CI：12.1-12.5）。不同亚组之间无统计学差异。独立性领域存在发表偏倚，使用修剪和填充法校正后的综合评分为 15.0（95%CI：14.6-15.5）。敏感性分析表明荟萃分析的结果是稳定的。地区可能是异质性的一个来源。东北地区工人的社会关系领域得分较高，而中部地区工人的环境领域得分较低。
中国工人在四个健康相关生活质量领域的得分均低于一般人群。地区可能是工人得分不同的潜在影响因素，需要进一步研究。综合评分可作为中国工人和全球职业健康研究中工作场所健康促进计划的基准。
