Mortality in 5 and 10 years for all causes in over 172,000 men classified for habitual physical activity at work was not substancially different between subjects classifed as sedentary, moderate and heavy workers. Mortality for coronary heart disease (CHD), for the same length of observation was statistically higher in sedentary and moderate than in heavy workers (ratio 1.7/1). Bivariate analysis considering both physical activity and responsibility at work, limited to 99,000 men aged 40-59 at entry for a period of 5 years having as end-point CHD, indicated that mortality is higher for higher levels of responsability. Partial correlation coefficients between physical activity and working responsibility on one side, and mortality for CHD on the other showed significant levels (-0.72 and 0.71 respectively) when considering eight combination of different activity and responsibility levels.
对超过17.2万名根据工作中的习惯性体力活动进行分类的男性进行的5年和10年全因死亡率研究发现，被归类为久坐不动、适度活动和重度活动的工作者之间的死亡率没有实质性差异。在相同的观察期内，久坐不动和适度活动的工作者患冠心病（CHD）的死亡率在统计学上高于重度活动的工作者（比率为1.7/1）。对9.9万名年龄在40 - 59岁、入职5年、以冠心病为终点的男性进行的双变量分析，同时考虑了体力活动和工作责任，结果表明，责任水平越高，死亡率越高。当考虑不同活动和责任水平的八种组合时，体力活动与工作责任之间以及冠心病死亡率之间的偏相关系数显示出显著水平（分别为-0.72和0.71）。
