摘要

背景。我们研究了克罗地亚人的预期寿命。材料与方法。据当地日报报道，一个月内有447名男性和366人死亡。采用中位数导数幂函数模型对数据进行分析。结果。男性和女性的平均死亡年龄分别为76岁和81岁。男性和女性的累积死亡率分别在60岁和65岁之后以恒定的速率增加(r2 = 0.99和0.98)。结论。在累积死亡率的确定性框架内，个体寿命是一个随机的生物事件。

The Stochastic Determinism of Aging and Death

Background. We have studied human life expectancy in Croatia. Materials and Methods. Local daily papers reported obituitairies for 447 men and 366 who died in a month period. The data were analyzed with the median derivative power function model. Results. The median age of death was 76 and 81 years for men and women, respectively. Cummulative mortality increases at a constant rate after the age 60 y and 65 y for men and women, respectively (r2 = 0.99 and 0.98). Conclusions. Individual life span is a stochastic (random) biological event within the deterministic frame of cumulative mortality.
