  • A study by Samuel Preston and Irma Elo uses nationally representative data to estimate the mortality hazards associated with diabetes, combining those hazards with the prevalence of diabetes to estimate the fraction of deaths attributable to diabetes and its effect on life expectancy. Evaluating the impact of diabetes on age-specific mortality may be salient in identifying the effect of rising obesity levels on US mortality and its contribution to racial/ethnic mortality disparities.

  • Research led by professor Samuel Preston and Penn alum Andrew Stokes of the School of Arts and Sciences measured the impact of rising obesity on mortality rates in the United States, based on the maximum body mass index of individuals between 1988 and 2011. They found that the obesity epidemic is to blame for preventing the U.S. from fully benefitting from factors that could lower mortality rates, such as medical advancements and reductions in smoking.

  • Sam Preston and Andrew Stokes have just published in the American Journal of Preventative Medicine. The full text of their new article "Prevalence and Trends in Lifetime Obesity in the U.S., 1988-2014" is now available online. Boston University, where Stokes teaches global health, has published a press release about their findings. Obesity affects the health of more than half of adults in the US and the PSC is proud to support the researchers investigating this epidemic.
