To evaluate whether safety climate items would be predictive of future physical and mental work ability among blue-collar workers.
Blue-collar workers (n=3822) from the Danish Work Environment and Health study replied to questions on safety climate, physical and mental work ability, and health in 2012 and 2014. Using multivariate logistic regression, we estimated the association of number of safety climate items (0-5) in 2012 with physical and mental work ability in 2014. Potential confounders included sex, age, socioeconomic class, occupational group, lifestyle (smoking habits and body mass index) and previous accidents.
In the fully adjusted model, workers reporting two and three or more safety climate problems (reference: 0) had higher risk for reduced physical work ability at follow-up (OR 1.29 [95% CI 1.03 to 1.61] and OR 1.52 [95% CI 1.27 to 1.84], respectively). Similar outcomes were observed for mental work ability. Using number of safety climate items as a continuous variable, a doseresponse association existed both for physical and mental work ability (trend-test <0.0001).
A dose-response association between the number of safety climate items at baseline and lower physical and mental work ability was detected after 2 years. Safety climate items should be highly prioritised in blue-collar companies.
评估安全氛围指标是否可预测蓝领工人未来的身体和精神工作能力。
丹麦工作环境与健康研究中的蓝领工人（n=3822）于 2012 年和 2014 年回答了关于安全氛围、身体和精神工作能力以及健康的问题。使用多变量逻辑回归，我们估计了 2012 年安全氛围指标（0-5）的数量与 2014 年身体和精神工作能力的相关性。潜在的混杂因素包括性别、年龄、社会经济阶层、职业群体、生活方式（吸烟习惯和体重指数）和既往事故。
在完全调整的模型中，报告存在两个或更多安全氛围问题的工人（参考：0）在随访时身体工作能力下降的风险更高（OR 1.29 [95% CI 1.03 至 1.61] 和 OR 1.52 [95% CI 1.27 至 1.84]）。对于精神工作能力也观察到类似的结果。使用安全氛围指标的数量作为连续变量，在身体和精神工作能力方面均存在剂量-反应关联（趋势检验<0.0001）。
在 2 年后，基线时安全氛围指标的数量与较低的身体和精神工作能力之间存在剂量-反应关联。安全氛围指标应在蓝领公司中得到高度重视。
