A more natural and wholly equivalent way, of expressing the log-linear relationship is to say that the age-specific mortality rate tends to decline by a fixed percentage with the passing of each calendar year.
The revised model has the form: (5a) [Mathematical Expression Omitted] with the restrictions: (5b) [Mathematical Expression Omitted] Here [Mu] (a) denotes an age-specific mortality rate, the rate of mortality of an organization at age a; [n.
The importance of using an appropriate denominator when assessing risk was portrayed in this study in that when the actual number of drivers at risk was used as a denominator in calculating the age-specific mortality rate estimates, the higher risk in younger age groups became apparent.
This procedure provides a simple, nonparametric estimate of the age-specific mortality rate for individuals with the characteristics of group g.
Submaximal repair at a given age has two effects: (1) It increases the reproductive output at that age; and (2) It increases the age-specific mortality rate for the following age, and all subsequent ages.
In summary, Shanks and Brundage have addressed 3 major mysteries of the 1918 influenza pandemic: high mortality rates/unexplained pathogenesis, unexplained age-specific mortality rate patterns, and evidence for wave-to-wave protection, with a unifying hypothesis.
Implicitly, senescence entails a progressive increase in the age-specific mortality rate (Kirkwood 1987).
The increase in mortality rate was limited to persons >64 years of age; during 1998-2004, the age-specific mortality rate of CDAD for persons >64 years of age doubled, from 76 per million population to 146 per million (Figure 3).
where ASMR (i) = Age-specific Mortality Rate of ith age group
Age-specific mortality rates (ASMRs) per 100 000 population were calculated and then age-standardised using the world standard population, [16] and compared across subdistricts.
As many of those born in 1950 are still alive, and these survivors are currently 65 and 66 years old, estimates of life expectancy depend in part on projections of future age-specific mortality rates.
