The composition of the seasonality of total death was ascertained. Vascular disease seasonality constitutes more than half. The remaining seasonality is influenced by respiratory disease. Surprisingly and of possible importance cancer mortality was not seasonal. Deaths from 'all other disease' and from 'injuries' is seasonal. Seasonality increases with age. In coronary and cerebrovascular disease death has a large seasonal fluctuation. On the other hand hospital admissions and survivors have a minor seasonal fluctuation--only cerebrovascular admissions reaching the chosen level of significance with a small seasonal amplitude. For vascular disease the ranking of seasonal fluctuation from greatest to least is--death outside hospital, total death, death inside hospital, admissions, survivors. It is death outside hospital presumably 'sudden' that imposes seasonality on coronary disease in general. For respiratory diseases not only death but hospital admissions and survivors have high amplitude seasonality with a much greater fluctuation than for death in vascular disease.
确定了总死亡人数季节性的构成。血管疾病季节性占比超过一半。其余季节性受呼吸道疾病影响。令人惊讶且可能具有重要意义的是，癌症死亡率并无季节性。“所有其他疾病”和“伤害”导致的死亡具有季节性。季节性随年龄增长而增加。在冠心病和脑血管疾病中，死亡存在较大的季节性波动。另一方面，住院人数和幸存者的季节性波动较小——只有脑血管疾病住院人数达到选定的显著水平，且季节性幅度较小。对于血管疾病，季节性波动从大到小的排序为——院外死亡、总死亡、院内死亡、住院人数、幸存者。大概是院外“突然”死亡将季节性因素强加于总体冠心病之上。对于呼吸道疾病，不仅死亡，而且住院人数和幸存者都有高幅度的季节性波动，其波动程度远大于血管疾病的死亡波动。
