Sunday (Nov 18) event at GSA Meeting in San Diego
Greetings,
We are pleased to share with you some more details about our upcoming Sunday event at the annual meeting of the Gerontological Society of America (GSA) in San Diego:
Symposium "Biodemography of Aging and Longevity"
Sunday, November 18, 2012, 8:00 AM-9:30 AM, Room 1A (San Diego Convention Center)
N.S. Gavrilova, L.A. Gavrilov "Biodemography of Old-Age Mortality in Humans and Rodents"
Abstract:
The growing number of persons living beyond age 80 underscores the need for accurate measurement of mortality at advanced ages. Earlier studies suggested that the exponential growth of mortality with age (Gompertz law) is followed by a period of deceleration, with slower rates of mortality increase.
This study challenges earlier conclusions with new data from the U.S. Social Security Administration’s Death Master File and survival records for laboratory mice and rats. Analyses of human extinct birth cohorts (1890-1898) demonstrated that mortality deceleration is far less pronounced when it is measured over monthly (rather than yearly) age intervals, and in higher-quality data. Mortality deceleration is also challenged by recent rodent data.
Simulations show that some estimates of mortality may produce spurious mortality deceleration, while the Sacher estimate turns out to be the most accurate estimate of hazard rate.
Feel free to disseminate this invitation among your colleagues, who may be interested.
Hope to see you there!
Kind regards,
-- Leonid and Natalia

Thanking You

Nice article, thanks for the information.
Biodemography of Aging and Longevity is an interesting topic. I used it as my thesis topic when i went for open university in dubai as this was my dream career to pursue.
