The death rate from Parkinson's disease (PD) were analyzed using Japanese vital statistics for 1950-1992. The age-adjusted PD death rate increased statistically significantly with the years between 1950 and 1992 for both sexes. However, decline in the PD death rate were observed among the population under 65 years old, while striking increases were seen among those over 70 years old. The changing patterns in the PD death rate might be explicable by a constantly improving ascertainment of PD, a true rise in the incidence of PD, particularly among the elderly, and a constantly increasing number of elderly people. There were remarkable differences in the PD death rates among the four marital categories in each sex. The mean age at death in PD increased from about 60 years in 1950 to 77 years in 1992 for both sexes.
利用1950 - 1992年日本生命统计数据对帕金森病（PD）的死亡率进行了分析。1950年至1992年间，经年龄调整的PD死亡率在两性中均随年份呈统计学显著上升。然而，65岁以下人群的PD死亡率有所下降，而70岁以上人群的PD死亡率则显著上升。PD死亡率的变化模式或许可以通过对PD确诊率的不断提高、PD发病率的真正上升（尤其是在老年人中）以及老年人口数量的持续增加来解释。两性中，PD死亡率在四种婚姻状况类别之间存在显著差异。两性PD患者的平均死亡年龄从1950年的约60岁增加到了1992年的77岁。
