Causes of death which contribute to the mortality crossover effect.

摘要: Abstract Death rates vary over the life cycle in a standard fashion, with mortality probabilities being highest at infant and older ages. Nevertheless, when age curves of are compared for different populations, they sometimes can be seen to intersect so that one population has higher death younger middle ages lower Past research shown this phenomenon is not due erroneous data probably result some type selection survival patterns. A sample pairs curves, 31 which cross do not, combinations countries dates analyzed discover causes associated crossover Cardiovascular “other unknown” diseases appear contribute strongly effect. Further should deal other comparisons explore underlying social environmental factors.
