A particular finding in our study was the close association between the changes in the overall death rate and the increase in the age-specific death rate
for the oldest age groups.
"where C indicates the crude mortality in the study population, Dj indicates the total number of deaths in our study population with the j-th mode of transmission, Ri indicates the age-specific death rate
in the i-th age group of the standard population, and Pij indicate the number of persons in the i-th age group for the j-th mode of transmission in our study population (5,6)."
They, however, model age-adjusted death rates instead of age-specific death rates
. Thus, their model fails to represent age-specific changes of mortality rates.
([dagger]) Underlying cause of death is defined as "the disease or injury which initiated the chain of morbid events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." ([section]) Age-specific death rates
per 1 million persons.
The age-specific death rates
from all causes were derived from the survival curve of the Vital Statistics Report (18).
* Expected deaths are the lowest three-state average age-specific death rate
times the age-specific state population rounded to the nearest whole number.
([section][section]) Age-adjusted death rates were calculated by applying age-specific death rates
to the 2000 U.S.
Researchers also found that age-specific death rates
between 2015 and 2016 increased for younger ages and decreased for older age groups.
No significant changes were noted in age-specific death rates
due to NCDs and other communicable, maternal, perinatal and nutritional conditions.
Using deaths from smoking-related cancers as a proxy for smoking, the authors estimate that age-specific death rates
for male smokers will decline between 2010 and 2040, largely because the heaviest smoking male cohorts were more than 80 years old in 2010.
Figure 3 (Panels A and B) highlights age-specific death rates
due to HIV/AIDS in Canada by five-year age group, sex and year.
(3) in 2005 compared the trend in age-specific death rates
for nine AIDS-related conditions (including tuberculosis and respiratory diseases) with age-specific death rates
for HIV as predicted by the Actuarial Society of South Africa model (ASSA 2000), and observed a high level of correlation, concluding that these diseases account for the 'missing' HIV cause of death statistics, and showing that only about 40% of deaths due to HIV are recorded as such.
