  1. Samuel H. Preston University of Pennsylvania Retirement Research Consortium Conference Washington, D.C. August 2, 2012 Projecting the Effect of Changes in Smoking and Obesity on Future Life Expectancy in the United States In Collaboration with Andrew Stokes and Bochen Cao, University of Pennsylvania and Neil Mehta, Emory University

  2. Figure 1. Trends in Smoking and Obesity in the United States Sources: Cigarette consumption data per adult per year are extracted from Tobacco Situation and Outlook Report Yearbook. U.S. Department of Agriculture, October 2007. Obesity data based on measured body mass index in NHANES from 1960 to 2010.

  3. Contrasting the Dynamics of Smoking and Obesity in the United States

  4. Table 1A. Transition Probabilities across Categories of Body Mass Index, US Adults Ages 25-84, 1998-2008

  5. Table 1B. Differences in Transition Probabilities (Standard Errors) between 1980-1990 and 1990-2000, US Adults Ages 25-84

  9. Data and Methods for the Analysis of the Mortality Risks of Obesity Data: Baseline data are obtained by pooling NHANES 3 (1988-1994) and NHANES continuous waves 1999-2004. Mortality data are obtained from the National Death Index. Sample size: 21,554 respondents and 2,976 deaths Method: Discrete hazards model, controlling for sex, race/ethnicity, educational attainment and smoking

  10. Baseline Model Parameters for Regression Equation Predicting Mortality as a Function of Current Obesity and Obesity at Age 25

  17. Equation for Projecting the Mortality Effects of Smoking • Where, • is the death rate at age a in cohort c • is the mean cumulative number of years smoked prior to age 40 for cohort c at age a • is an indicator of age category a • is the coefficient of age category a • is the coefficient of
