The aim of this study was to investigate if working in a cold environment and feeling cold at work are associated with chronic pain (ie, lasting ≥3 months).
We used data from the sixth survey (2007-2008) of the Tromsø Study. Analyses included 6533 men and women aged 30-67 years who were not retired, not receiving full-time disability benefits and had no missing values. Associations between working in a cold environment, feeling cold at work and self-reported chronic pain were examined with logistic regression adjusted for age, sex, education, body mass index, insomnia, physical activity at work, leisure time physical activity and smoking.
779 participants reported working in a cold environment ≥25% of the time. This exposure was positively associated with pain at ≥3 sites (OR 1.57; 95% CI 1.23 to 2.01) and with neck, shoulder and leg pain, but not with pain at 1-2 sites. Feeling cold sometimes or often at work was associated with pain at ≥3 sites (OR 1.58; 95% CI 1.22 to 2.07 and OR 3.90; 95% CI 2.04 to 7.45, respectively). Feeling cold often at work was significantly and positively associated with pain at all sites except the hand, foot, stomach and head.
Working in a cold environment was significantly associated with chronic pain. The observed association was strongest for pain at musculoskeletal sites and for those who often felt cold at work.
本研究旨在调查在寒冷环境中工作以及工作时感觉寒冷是否与慢性疼痛（即持续时间≥3个月）有关。
我们使用了特罗姆瑟研究第六次调查（2007 - 2008年）的数据。分析纳入了6533名年龄在30 - 67岁之间、未退休、未领取全职残疾福利且无缺失值的男性和女性。通过对年龄、性别、教育程度、体重指数、失眠、工作时的身体活动、休闲时间的身体活动和吸烟进行调整的逻辑回归分析，研究在寒冷环境中工作、工作时感觉寒冷与自我报告的慢性疼痛之间的关联。
779名参与者报告在≥25%的工作时间处于寒冷环境中。这种暴露与≥3个部位的疼痛呈正相关（比值比1.57；95%置信区间1.23至2.01），与颈部、肩部和腿部疼痛有关，但与1 - 2个部位的疼痛无关。工作时有时或经常感觉寒冷与≥3个部位的疼痛有关（比值比分别为1.58；95%置信区间1.22至2.07和3.90；95%置信区间2.04至7.45）。工作时经常感觉寒冷与除手、脚、胃部和头部外的所有部位的疼痛均呈显著正相关。
在寒冷环境中工作与慢性疼痛显著相关。观察到的关联在肌肉骨骼部位的疼痛以及那些工作时经常感觉寒冷的人群中最为强烈。
