Previous studies have indicated an increased incidence of myocardial infarction among railway engine drivers.
To analyse whether somatic risk factors for myocardial infarction among male drivers in different geographical areas in Sweden differed from that in general population samples drawn from the same geographical areas.
A cross-sectional study comparing drivers and men from the general population.
Engine railway drivers aged 25-59 years (n = 2318) were compared with randomly selected men (n = 3016) with respect to their serum cholesterol, systolic and diastolic blood pressures and smoking habits.
The levels of the risk factors did not differ between engine drivers and the reference groups except for the Stockholm area which showed a higher percentage of tobacco smokers as well as higher means for systolic and diastolic blood pressures. The risk ratio compared with the reference samples was significantly elevated in Stockholm but not in any of the other areas.
These somatic risk factors for myocardial infarction do not explain the approximately 40% reported increase in myocardial infarction incidence among railway engine drivers. In the following study, psychosocial factors will also be examined.
先前的研究表明铁路机车司机中心肌梗死的发病率有所增加。
分析瑞典不同地理区域男性司机中心肌梗死的躯体危险因素是否与来自相同地理区域的一般人群样本中的危险因素不同。
一项比较司机与一般人群男性的横断面研究。
将年龄在25至59岁之间的铁路机车司机（n = 2318）与随机选取的男性（n = 3016）在血清胆固醇、收缩压和舒张压以及吸烟习惯方面进行比较。
除斯德哥尔摩地区外，机车司机与对照组之间的危险因素水平没有差异。斯德哥尔摩地区吸烟者的比例更高，收缩压和舒张压的均值也更高。与对照样本相比，斯德哥尔摩地区的风险比显著升高，但其他地区均未出现这种情况。
这些心肌梗死的躯体危险因素无法解释铁路机车司机中心肌梗死发病率报告中约40%的增长。在接下来的研究中，还将对社会心理因素进行考察。
