背景:轮班工作涉及在周一至周五上午9点至下午5点的标准工作时间之外工作,可能包括晚上工作,晚上,周末,或旋转移位模式。由于轮班工人睡眠不足,昼夜节律被打乱,据报道,他们的体重高于临时工。
目的:这项荟萃分析旨在确定轮班工人(SW)是否比日间工人(DW)更容易患更高的体重指数(BMI)。它还解决了轮班工作暴露的持续时间,性别,或职业类型影响BMI值。
方法:PubMed的四个数据库,EBSCO主机,Scopus,和WebofScience进行了搜索,以查找截至2023年10月发布的报告。
结果:涉及693449名参与者的63项研究符合我们的纳入标准。荟萃分析显示,与非轮班相比,轮班工作对BMI值具有显着影响(标准平均差;SMD:0.10kg/m2[95%置信区间;95%CI:0.07;0.13;p<.001])。亚组分析显示,对于轮班工人工作≥13年的研究(SMD:0.10kg/m2[95%CI:0.04;0.17;p=.0018]),轮班工作显着增加了BMI(按轮班工作经验的中位数计算;SMD:0.14kg/m2[95%CI:0.10;0.18;p<.001])以及工业(SMD:0.0012)占主导地位的研究(0.05/
结论:我们发现,一般来说,与白天的工人相比,按轮班时间表工作会增加BMI,特别是在这个工作计划中雇用男性的情况下,对于长期工作(≥13年)的轮班工人,以及受雇于工业和其他类型职业的轮班工人(例如,航空公司的工作人员,消防员,警察,蓝领,安全人员,公共汽车司机,垃圾收集器,铁路工人,邮政,石油和天然气工人)。
Shift work involves working outside the standard working hours of 9 am to 5 pm Monday to Friday and may include working evening, night, weekend, or rotating shift patterns. Since shift workers sleep less and their circadian rhythms are disrupted, they are reported to have higher body weight than day workers.
This meta-analysis aims to determine whether shift workers (SW) are more prone to higher body mass index (BMI) than their day workers (DW) counterparts. It also addresses the question of whether the duration of shift work exposure, sex, or occupational type affect BMI value.
Four databases that is PubMed, EBSCO Host, Scopus, and Web of Science were searched for reports published up to October 2023.
Sixty-three studies involving a total of 693 449 participants met our inclusion criteria. Meta-analyses showed a significant effect of shift work on BMI value (standard mean difference; SMD: 0.10 kg/m2 [95% confidence interval; 95% CI: 0.07; 0.13; p < .001]) as compared with non-shift counterparts. Subgroup analysis revealed that shift work significantly increased BMI for studies where male working on this job schedule (SMD: 0.10 kg/m2 [95% CI: 0.04; 0.17; p = .0018]) for studies where shift workers worked ≥13 years (calculated as the median of shift work experience; SMD: 0.14 kg/m2 [95% CI: 0.10; 0.18; p < .001]) as well as for studies where industrial (SMD: 0.12 kg/m2 [95% CI: 0.05; 0.19; p = .0012]) and other type of occupations were dominated (0.12 kg/m2 [95% CI: 0.07; 0.16; p < .001]).
We found that in general working on a shift schedule increases BMI as compared with day workers, especially in case of male employed in this job schedule, for shift workers working for long periods of time (≥13 years), and for shift workers employed in industry and other type of occupations(e.g., airline workers, firefighters, police officers, blue collar, security personnel, bus drivers, garbage collectors, railway workers, postal, oil and gas workers).
