Description: Transcript of the Q&A period from Session 6B: Health Status and its Impact on Mortality

Description: This paper introduces the predictive modeling tools to mortality research. The predictive modeling is applied to study how multiple risk drivers such as demographic characteristics and social and economic status impact the mortality improvement of the advanced age population. The paper provides both the theoretical frameworks and the application aspects of the predictive modeling process. As the result, a mortality risk score was derived in differentiating the mortality risk for the advanced age population.

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: This paper develops the binomial version of the Lee-Carter model and provides a comparative study of simulation strategies for assessing risk in mortality rate predictions and associated estimates of life expectancy and annuity values in both period and cohort frameworks.

Description: Recent trends in mortality suggest that future gains in life expectancy will occur after age 80. This fact stresses the need and the importance to obtain precise measures of mortality at the highest ages, which are always subject to uncertainty due to misreporting of age at death.

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.

Description: We propose an age-shift model to modify the LC model and deal with the problem of parameters. The proposed method attains smaller estimation errors with respect to mean absolute percentage error or mean square error. We also apply the proposed age-shift model to the mortality rates of these four countries to evaluate the longevity risk in annuity products by measuring life expectancy.

Description: The percentage of the population who are obese has grown dramatically worldwide over the last several decades, although stabilizing recently in the United States. Studies have found the effects on mortality to be inconsistent and controversial because of methodological differences and the complexity of the relationship between obesity and mortality. This paper discusses this relationship and sheds light on the likely effects of this epidemic. Issues associated with the so-called obesity-mortality paradox, where mortality experience is lower for those individuals who are overweight and in some who are obese compared with the mortality of those in the normal weight category, are examined. Although certain recently reported studies of the relationship between mortality and obesity indicate that obesity is related to a reduced percent of additional mortality, this may in part be due to the shorter average time that those currently obese have been exposed to their condition. Nevertheless, the amount of health care costs and rates of disability associated with being obese are significant, contributing to the increase in overall health care costs as they become more numerous and age. Although obesity is being addressed with a great deal of activity and publicity, they will continue to prove challenging for individuals and society to manage and overcome.
