Pure-Air: A Global Assessment of Household and Outdoor Air Pollution and Cardiopulmonary Disease

摘要

We are adding an air pollution study (PURE-AIR) to the ongoing prospective urban and rural epidemiological (PURE) cohort, which includes ～225,000 adults aged 35-70 years living in 850 communities in 27 countries. Here, we will describe the comprehensive methods used to estimate outdoor, household and personal air pollution exposures. Outdoor estimates include PM2.5, from an existing 1x1km satellite surface, and NO2, from a newly created global LUR model. In addition, we are measuring PM2.5 for 48-hr periods using the UPAS monitor in ～4,500 households and concurrently for ～1,200 individuals. Individuals also wear a silicon wristband to capture organic exposures. To-datewe have collected data for 1,400 households and 300 individuals. Data collection will continue for the next 18 months. Preliminary outdoor, household and individual exposure assessment results will be presented and future plans for epidemiological analyses.
