Population Health, Burden of Disease, and Comparative Risk Assessment
Consistent and comparable information on health outcomes, risk factors, and interventions at the population level is needed to inform planning, resource allocation, program implementation, monitoring and evaluation.
We develop, parameterize, and apply epidemiology-based models to quantify the effects of environmental, behavioural, nutritional, and metabolic risk factors and their interventions on population health, globally and in specific countries. These analyses, known as Comparative Risk Assessment (CRA), are widely used to inform priority setting by national and international agencies.
Recent work has focused on analytics and data for multiple risk factors and time varying risk factors. The original CRA Study formed the scientific basis of the World Health Report 2002: Reducing Risks, Promoting Healthy Life . The CRA analysis is currently being updated in the Global Burden of Diseases, Injuries, and Risk Factors 2010 Study and will provide estimates of the global and regional exposure to and burden of selected risk factors in 1990 and 2005.
