The aim of the study was to determine the association between occupational ambient cold exposure and neck-shoulder pain (NSP), low back pain (LBP), and radiating LBP.
The study cohort comprised of 3,843 working subjects in northern Sweden who answered a baseline (spring 2015) and a follow-up questionnaire (spring 2021). NSP, LBP, and radiating LBP were assessed in both surveys. Occupational cold exposure was assessed at baseline, on a whole number numerical rating scale (NRS) and categorized in quartiles. Binary logistic regression determined the association between cold exposure at baseline and incident NSP, LBP, and radiating LBP, adjusted for age, gender, body mass index, smoking, mental stress, and physical workload.
There were statistically significant associations between high occupational ambient cold exposure (NRS 5-7 and NRS 8-10) and NSP (1.59; 95% CI 1.08-2.33 and OR 1.50; 95% CI 1.03-2.19); NRS 8-10 and LBP (OR 1.61; 95% CI 1.13-2.29); and NRS 5-7 and radiating LBP (OR 1.87; 95% CI 1.12-3.16). Gender-stratified analyses showed statistically significant associations between high occupational ambient cold exposure (NRS 5-7 and NRS 8-10) and NSP (OR 1.97; 95% CI 1.07-3.61 and OR 1.97; 95% CI 1.06-3.67) for men and between NRS 8-10 and LBP (OR 1.82; 95% CI 1.14-2.91) and NRS 5-7 and radiating LBP (OR 2.20; 95% CI 1.15-4.24) for women.
Occupational ambient cold exposure was associated with NSP, LBP, and radiating LBP, and should be recognised as a possible occupational risk factor.
本研究旨在确定职业环境寒冷暴露与颈肩部疼痛（NSP）、下腰痛（LBP）和放射状 LBP 之间的关联。
研究队列包括来自瑞典北部的 3843 名工作者，他们在基线（2015 年春季）和随访问卷（2021 年春季）中回答了问题。在两项调查中均评估了 NSP、LBP 和放射状 LBP。职业寒冷暴露在基线时使用全数字评分量表（NRS）进行评估，并分为四分位数。二元逻辑回归确定了基线时的寒冷暴露与新发 NSP、LBP 和放射状 LBP 之间的关联，调整了年龄、性别、体重指数、吸烟、精神压力和体力工作负荷。
高职业环境寒冷暴露（NRS 5-7 和 NRS 8-10）与 NSP（1.59；95%CI 1.08-2.33 和 OR 1.50；95%CI 1.03-2.19）、NRS 8-10 与 LBP（OR 1.61；95%CI 1.13-2.29）和 NRS 5-7 与放射状 LBP（OR 1.87；95%CI 1.12-3.16）之间存在统计学显著关联。性别分层分析显示，高职业环境寒冷暴露（NRS 5-7 和 NRS 8-10）与 NSP（OR 1.97；95%CI 1.07-3.61 和 OR 1.97；95%CI 1.06-3.67）之间存在统计学显著关联，NRS 8-10 与 LBP（OR 1.82；95%CI 1.14-2.91）和 NRS 5-7 与放射状 LBP（OR 2.20；95%CI 1.15-4.24）之间存在统计学显著关联。
职业环境寒冷暴露与 NSP、LBP 和放射状 LBP 相关，应被视为一种可能的职业危险因素。
