Both low and high temperature may increase the risk of stroke mortality

Neurology: 8/14/13

Objective: To examine temperature in relation to stroke mortality in a multicity time series study in China.

Methods: We obtained data on daily temperature and mortality from 8 large cities in China. We used quasi-Poisson generalized additive models and distributed lag nonlinear models to estimate the accumulative effects of temperature on stroke mortality across multiple days, adjusting for long-term and seasonal trends, day of the week, air pollution, and relative humidity. We applied the Bayesian hierarchical model to pool city-specific effect estimates. Read more
