影响男女性人口寿命变化的病因探讨

Research on Pathogenic factors Affecting the Population′s life Tendency in Both Sexes

本文用改良式净死亡概率模型研究影响阆中男女性寿命的因素。揭示新生儿病、急性传染病、消化系病、意外死亡、结核病、肺炎等死亡率的下降对寿命增长的贡献较大;恶性肿瘤、脑血管病死亡率的上升对寿命增长呈负贡献,以男性突出。其结果与阆中近十多年死亡模式的变化趋势基本一致。

This paper studied the factors affecting the population life tendency in Langzhong city with modified pure death probability model. It sho- wed the main contribution to the increased life tendency of the city was the decreased mortality of infant disease, acute infectious disease, digestive system disease, accidental death, tu- berculosis and hepatitis, while the negative con tribution to it was malignent tumor and cerebro- vascular disease espicially in male. This result was similar to the' death model' variable tend- ency in recent ten years in Langzhong city.
