This study examined the relationship between frequency of working from home and low back pain (LBP), considering the quality of work environment.
The study was based on a cross-sectional internet-based survey. Of 33 302 respondents, data from 12 774 desk workers were retained for analysis. We used a 0-10 numerical rating scale to assess LBP. Work environment was assessed using five subjective questions. Mixed-effects logistic regression nested by city level was used to analyze the relationship between frequency of working from home and LBP, stratified by work environment condition.
The prevalence of LBP was 21.0%. Among those reporting a poor work environment, as opposed to almost never working from home, the multivariate odds ratio (OR) of LBP were as follows: working from home less than 1 day per week: OR = 1.25, 95% CI: 0.89-1.76, p = .190; 2-3 days per week: OR = 1.58, 95% CI: 1.16-2.16, p = .004; and 4 or more days per week: OR = 1.82, 95% CI: 1.38-2.40, p < .001. By contrast, among those reporting a good work environment, the OR of LBP did not increase as the frequency of working from home increased.
The relationship between LBP and frequency of working from home was found to vary with the quality of the work environment; more specifically, LBP was associated with frequency of teleworking in a poor work environment. This study suggests that employers should give more support to their employees in promoting a good work environment to prevent LBP. (Words: 240/250).
本研究旨在考虑工作环境质量的情况下，探讨在家工作频率与下背痛（LBP）之间的关系。
本研究基于一项横断面互联网调查。在 33302 名受访者中，保留了 12774 名办公人员的数据进行分析。我们使用 0-10 数字评分量表评估 LBP。使用五个主观问题评估工作环境。采用按城市水平嵌套的混合效应逻辑回归分析在家工作频率与 LBP 的关系，并按工作环境条件进行分层。
LBP 的患病率为 21.0%。在报告工作环境较差的人群中，与几乎从不在家工作相比，LBP 的多变量优势比（OR）如下：每周在家工作少于 1 天：OR=1.25，95%CI：0.89-1.76，p=0.190；2-3 天/周：OR=1.58，95%CI：1.16-2.16，p=0.004；每周 4 天或更多天：OR=1.82，95%CI：1.38-2.40，p<0.001。相比之下，在报告工作环境较好的人群中，随着在家工作频率的增加，LBP 的 OR 并未增加。
在家工作频率与 LBP 之间的关系随工作环境质量的不同而有所不同；更具体地说，在工作环境较差的情况下，LBP 与远程工作频率相关。本研究表明，雇主应给予员工更多支持，以促进良好的工作环境，预防 LBP。（词汇量：240/250）
