Looking for Sponsors of Scientific Meeting on Aging & Longevity

Greetings,

We wonder whether you may know a person or organization willing to sponsor the GSA Interest Group workshop "Societal Implications of Delaying Aging" at the upcoming 2015 Annual meeting of the Gerontological Society of America (GSA) in Orlando, Florida, on November 19-21. 

This sponsorship can bring a positive publicity to potential donor, and may allow to promote more research support for aging and longevity studies.   Please advise.

More details are available upon your request.

Thank you, and looking forward to hear from you.

Kind regards,

-- Leonid and Natalia

P.S.: Abstract

Increasing  numbers  of people surviving  to  advanced  ages  pose serious challenge to government pension systems and to most developed societies.  Therefore, accurate estimates of mortality at advanced ages are essential to improving forecasts of mortality and the population size of the oldest old age group.  


In this paper we present some new approaches to mortality and population projections at older ages.  We apply modified method of mortality shifting to the data of Sweden and make mortality projections up to year 2050.  Specifically, we identify the best historic time interval for identifying the rate of mortality decline to use in mortality extrapolation.  In the case of Sweden, the best historic interval is 1980 through 2008 years for both men and women.  For men, the rate of mortality decline is almost twice as high as this rate for women. 

Using assumptions about log-linear decline of mortality over time and the exponential increase of mortality with age we conducted mortality projections for Swedish population over the next 50 years.  According to these projections, life expectancy at age 25 will increase from 54.07 years in 2005 to 62.71 years in 2050 for men and from 58.20 years to 63.50 years for women.  


These advances in life expectancy will not result in the growth of native population and it is expected that the native population of Sweden starts to decline after 2036 (assuming the birth rate remains unchanged)
