The aim of this study was to assess whether exposure to urban pollution in outdoor workers, may alter plasma cortisol concentrations also in relation to the effect of smoking and drinking habits. The research was carried out on 498 outdoor police workers, divided into three groups; Group A: traffic policemen (TP), Group B: drivers (D), Group C: Other duties (OD). To evaluate separately the effect of using alcohol and smoking, each group was divided into three subgroups: (1) non-smokers and non-drinkers, (2) smokers and non-drinkers, (3) non-smokers and drinkers. Our results show cortisol mean values were significantly higher in the TP group compared to the D and OD groups without significant differences between the last two groups. The results suggest that exposure to pollutants associated with urban psychosocial stress may play a more important role on plasma cortisol levels than smoking and alcohol.
本研究旨在评估户外工作者暴露于城市污染中是否会改变血浆皮质醇浓度，以及这种改变是否与吸烟和饮酒习惯有关。研究对象为 498 名户外警察工作人员，分为三组：A 组：交通警察（TP），B 组：驾驶员（D），C 组：其他职务（OD）。为了分别评估饮酒和吸烟的影响，每组又分为三个亚组：（1）不吸烟者且不饮酒者，（2）吸烟者且不饮酒者，（3）不吸烟者且饮酒者。我们的结果显示，TP 组的皮质醇平均值明显高于 D 组和 OD 组，后两组之间无显著差异。结果表明，与城市心理社会压力相关的污染物暴露可能比吸烟和饮酒对血浆皮质醇水平有更重要的影响。
