Morbidities calculation: Guidelines and walkthrough

Local air pollution can have a variety of adverse health impacts. Some are fatal and others are not. Non-fatal health impacts are referred to as morbidities and range from increased asthma symptoms to hospitalization. This study outlines the data and calculations necessary to assess the impact of fine particulate matter on morbidity rates. The walkthrough section and accompanying spreadsheet provide step-by-step guidance for non-specialists with an interest in considering the morbidity reduction gained from policies to reduce pollution exposure. The appendices explore the sensitivity of a morbidity assessment to the time resolution of exposure data and the use of internationally transferred incidence rates and exposure-response functions in lieu of local data.
