34 This was to allow the rate of admission to be compared over time despite changing age structure of the population.
The incidence of all infections increased with age (particularly pneumonia) and increased over the study period; our age-standardization analyses suggest that this increasing trend was driven by the changing age structure of the population.
When computing the future excess mortality attributable to heat waves, we take into account the changing age structure of the population by applying age category specific relative risks estimated from the age-stratified time-series models.
15 However, Mikuls et al showed that the overall incidence of consultations for gout remained relatively stable throughout the 1990s, 10 suggesting that any increase in prevalence might be largely attributable to the changing age structure of the population.
Results in 2004 vs. 1989 can therefore be directly compared (i.e. differences do not reflect the changing age structure of the populations between 1989 and 2004).
To adjust for the changing age structure of type 2 diabetics between 1994 2001 we used the 2001 population of DIN to age standardise prevalence rates using the direct method.
A limitation of the study is the lack of additional information about the cases, in particular their age, not allowing the use of a direct standardization method to account for the changing age-structure of the population, giving rise to potential bias due to the higher vulnerability of ageing populations to heat stress [ 2].
30 The changing age structure in Poland as well as other countries is necessitating the creation of opportunities for this population segment to age positively.
However, calculations controlling for the changing age structure in England and Wales during the surveillance period generates a consistent increase in risk among those >60 years of age.
The proportion of individuals with disabilities is rising, possibly due to a changing age structure and to an increase in chronic health conditions [ 1].
The refinements of demographic predictions, including the consequences of changing age structures in developed and developing countries, offer an important update on the kinds of futures that human populations might expect.
