The Global Burden of Disease (GBD) study seeks to develop a comprehensive suite of estimates of death and disability for 301 diseases and injuries. For each health outcome we estimate deaths, prevalence, years of life lost (YLL), years lived with disability (YLD) and disability adjusted life years (DALY). Estimates are produced for each of 188 countries, for the years 1990 through 2013, by age and sex. In this seminar we’ll take a high-level look at our approach to burden estimation for GBD. We’ll review burden metrics (YLLs, YLDs and DALYs) and their calculation, and discuss the methods used to estimate disease prevalence and mortality. Finally, we’ll review some of the key results from the GBD study and look at the visualization tools available to explore those results.
About the Speaker
Jeff Stanaway, PhD, MPH, is Acting Assistant Professor at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. He is part of the Global Burden of Disease research team and models morbidity and mortality from enteric and neglected tropical diseases. His research focuses on macro-epidemiology with a special interest in understanding connections between the physical environment (e.g., climate and land cover) and the spatiotemporal distribution of disease and how these connections may inform surveillance and research. Dr. Stanaway received his PhD in Epidemiology from the University of Washington and his Master of Public Health from the University of Arizona.

Public bicycle share programs (PBSPs) are growing in popularity in around the world. We evaluated the effect of North American PBSPs, which typically do not offer helmets with rentals, on the occurrence of bicycle-related head injuries. An ecological study design was employed, comparing trauma center admissions for bicycle-related injuries from 5 cities with PBSPs and 5 comparison cities over time. Results showed that in PBSP cities, the proportion of head injuries among bicycle-related admissions significantly increased, whereas the proportion in comparison cities remained similar did not. Odds ratios for bicycle-related head injury were 1.30 (95% CI = 1.13, 1.67) in PBSP cities and 0.94 (95% CI = 0.79, 1.11) in control cities (adjusted for age and city) when we compared the period after implementation to the period before. Implementation of a PBSP was associated with significantly greater risk of head injury among bicycle-related trauma center admissions.
