我国职业人群加班与颈部肌肉骨骼疾患关系的Meta分析

A meta-analysis of the relationship between overtime work and neck musculoskeletal disorders in Chinese occupational population

目的系统评价加班对我国职业人群颈部肌肉骨骼疾患的影响。方法于2023年8月,在中国知网(CNKI)、万方数据库(WanFang Database)、维普中文科技期刊全文数据库(VIP)、中国生物医学文献服务系统(SinoMed)和PubMed,检索关于加班与颈部肌肉骨骼疾患关系的文献。检索范围为2023年6月30日前发表的中文和英文文献。使用美国卫生保健研究和质量机构(AHRQ)横断面调查质量评价标准评估文献质量。使用Stata 15.0软件计算合并OR值,采用亚组分析和meta回归探索异质性来源。结果最终共纳入32篇文献,均为中文文献,总样本量为36 003人,文献质量评分在5~7分。异质性检验显示文献不存在异质性(I^(2)=20.3%,P=0.156),选择固定效应模型计算合并OR值。加班对职业人群颈部肌肉骨骼疾患影响的合并OR值为1.51(95%CI:1.42~1.60,P<0.001)。亚组分析显示,<35岁组职业人群的合并OR值高于≥35岁组(P<0.05),而按平均工龄、男性占比、OR值类型、样本量大小和行业分类的亚组间合并OR值差异无统计学意义(P>0.05)。结论加班是我国职业人群颈部肌肉骨骼疾患的危险因素,应合理安排劳动者工作时长,以降低颈部肌肉骨骼疾患的患病率。

ObjectiveTo systematically evaluate the effect of overtime work on neck musculoskeletal disorders of occupational population in China.MethodsIn August 2023,the literatures on the relationship between overtime work and neck musculoskeletal disorders were searched in China National Knowledge Infrasture(CNKI),WanFang Database,Chinese Science&Technology Journal Database(VIP),China Biomedical Literature Service System(SinoMed)and PubMed.The search scope was Chinese and English literatures published before June 30,2023.The Quality of literature studies was evaluated using the Agency for Healthcare Research and Quality(AHRQ)cross-sectional study quality evaluation criteria.The Stata 15.0 software was used to calculate combined OR values,and subgroup analysis and meta regression were used to explore the sources of heterogeneity.ResultsA total of 32 literatures were included,all of which were in Chinese,with a total sample size of 36003 people,and the literature quality scores were 5-7 points.Heterogeneity test showed that there was no heterogeneity between the literatures(I^(2)=20.3%,P=0.156),so fixed effect model was selected to calculate the combined OR value.The combined OR value of overtime work on neck musculoskeletal disorders was 1.51(95%CI:1.42-1.60,P<0.001).Subgroup analysis showed that the combined OR of occupational population<35 years old group was higher than that in the≥35 years old group(P<0.05).But there were no significant differences in the combined OR values in the subgroups classified by average years of service,male proportion,type of OR values,sample size and industry classification(P>0.05).ConclusionOvertime work is a risk factor for neck musculoskeletal disorders in Chinese occupational population.Working hours should be rationally arranged to reduce the prevalence of neck musculoskeletal disorders.
