Description: Transcript of the Q&A period from Session 6A: Projection and Statistical Modeling of Mortality at Late Age

Description: The effect on mortality of the reduction in smoking and the increase obesity in the U.S. is estimated based on historical and projected patterns.

Description: Discussion on Living to 100 Session 4B. Papers presented: Typology and Review of Measures of Human Aging, Longevity and Superlongevity with Applications to US Data and Some Implications for US Public Programs and, Mortality Measurements at Advanced Ages: A Study of the Social Security Master Death File

Description: Transcript of Session 3A from the 2008 Living to 100 Symposium discusses the use of mortality in social insurance systems in the US and Canada.

Description: Transcript of the Q&A period from Session 5A. The paper presented proposes a new method to price the longevity risk premia in order to tackle the pricing obstacle.

Description: Centenarians persons living to age 100 and over represent a population that could be useful in identifying factors leading to long life and avoidance of fatal diseases. This study explores whether people living to 100 and beyond were any different from their peers at their middle age 30 years in terms of their physical characteristics height and body build, occupation and marital status.

Description: Estimation of hazard rates at extremely old ages poses serious challenges to researchers: 1 The observed mortality deceleration may be at least partially an artifact of mixing different birth cohorts with different mortality heterogeneity effect 2 Standard assumptions of hazard rate estimates may be invalid when risk of death is extremely high at old ages 3 Ages of very old people may be exaggerated. In this paper we propose an alternative approach, which gives an opportunity to resolve the first two problems by compiling data for more homogeneous single-year birth cohorts with hazard rates measured at narrow monthly age intervals. Possible ways of resolving the third problem of hazard rate estimation were elaborated.

Description: Discussion of Session 5B: Papers presented: Data Validation and Measurement of Cohort Mortality among Centenarians in Quebec and Physical and Socioeconomic Characteristics at a Young Age as Predictors of Survival

Description: This paper presents recent trends in obesity prevalence in significant population segments, including overall effects by age, gender and certain racial and ethnic groups, and discusses the ways in which obesity can influence mortality in each of these segments. It provides a synthesis of reported mortality experience relating to these behaviors by risk factors and diseases that will affect any mortality projection.
