The article describes mortality from ischaemic heart disease, including sudden, unexpected death, among males aged 30-69 years in all 19 Norwegian counties for the period 1966-87. During this period, the age-adjusted mortality rate in Norway for the 30-69 year age group was highest in 1966-70, and declined by 15% until 1983-87. The decline in mortality was greatest in the 40-49 year age group, but was also clearly evident in the 50-59 and 60-69 year groups. In twelve of the counties there was a statistically significant (p less than 0.05) decrease in mortality from 1966-70 to 1983-87. In one county, Oppland, located in central south-eastern Norway, mortality increased by 19% (p less than 0.01). The increased mortality in this county was most prominent in the 50-59 year group (34%, p less than 0.01). The most favourable change in mortality took place in Rogaland, in south-western Norway, where mortality decreased by 29% (p less than 0.001) from 1966-70 to 1983-87. Positive changes in mortality were also seen in Finnmark, a county with traditionally very high mortality rates. This study was not designed to explain the regional differences in mortality, but the authors point to principal explanatory factors. The regional differences in mortality time trends might be an argument for geographical differentiation of preventive measures.
本文描述了1966年至1987年期间挪威所有19个郡30至69岁男性缺血性心脏病死亡率，包括猝死和意外死亡情况。在此期间，挪威30至69岁年龄组的年龄调整死亡率在1966 - 1970年最高，到1983 - 1987年下降了15%。死亡率下降在40至49岁年龄组最为显著，但在50至59岁和60至69岁年龄组也很明显。在12个郡，1966 - 1970年至1983 - 1987年期间死亡率有统计学显著下降（p小于0.05）。在挪威中东南部的奥普兰郡，死亡率上升了19%（p小于0.01）。该郡死亡率上升在50至59岁年龄组最为突出（34%，p小于0.01）。死亡率变化最有利的是挪威西南部的罗加兰郡，从1966 - 1970年到1983 - 1987年死亡率下降了29%（p小于0.001）。在传统死亡率非常高的芬马克郡，死亡率也出现了积极变化。本研究并非旨在解释死亡率的区域差异，但作者指出了主要的解释因素。死亡率时间趋势的区域差异可能是预防措施进行地理差异化的一个依据。
