Acute exposure to particulate matter with aerodynamic diameter <2.5 μm (PM2.5) is associated acute cardiovascular and cerebrovascular mortality. The aim of this study was evaluate these associations specific causes mortality in Mexico City.We obtained daily records for City from 2004 2013 people ≥25 ≥65 years old. Exposure PM2.5 assessed estimates a new hybrid spatiotemporal model using satellite measurements aerosol optical depth compared ground level missing data estimated generalized additive models PM2.5. We fitted Poisson regression distributed lags all outcomes.An increase 10 µg/m3 increased (1.22%; 95% confidence interval, 0.17-2.28) (3.43%; 0.10-6.28) lag days 0 1 (lag 0-1). Stronger effects were identified hemorrhagic stroke years. Associations slightly smaller PM2.5.These results support the evidence that risk causes.
