The coronary heart disease (CHD) mortality rates for men aged 35-44 years decreased by 25% from 1966-70 to 1976-80. In older age groups only a modest decline was observed. The decrease in CHD mortality is probably due to a decrease in incidence. The reason for the decline is not known, but some changes in health-related behaviour have occurred in Norway, probably already starting in the 1960s. There was an increase in meat, sugar and total fat consumption and a decrease in the intake of cereals both before and after the Second World War. These trends seem to have slowed down and in a recent survey 44% of the population reported changes towards a low fat diet. The percentage of non-smokers is increasing, particularly since 1975-76. Physical activity in leisure time has increased since the mid-70s but there are social gradients with the most active subjects being recruited from the higher social strata. The improved medical care of CHD patients is not thought to have had a major impact upon the decline in the mortality rates. The most probable explanation for the changes is an increase of non-smokers and a turn towards a less coronary prone diet.
35至44岁男性的冠心病死亡率在1966 - 1970年至1976 - 1980年间下降了25%。在年龄较大的群体中，仅观察到适度下降。冠心病死亡率的下降可能是由于发病率的降低。下降的原因尚不清楚，但挪威在健康相关行为方面已经发生了一些变化，可能在20世纪60年代就已开始。第二次世界大战前后，肉类、糖和总脂肪的消费量增加，谷物摄入量减少。这些趋势似乎已经放缓，在最近的一项调查中，44%的人口报告有转向低脂饮食的变化。不吸烟者的比例在增加，特别是自1975 - 1976年以来。自70年代中期以来，休闲时间的体育活动有所增加，但存在社会梯度，最活跃的人群来自较高社会阶层。冠心病患者医疗护理的改善被认为对死亡率的下降没有重大影响。这些变化最可能的解释是不吸烟者的增加以及转向不易引发冠心病的饮食。
