Abstract
Extreme weather events are closely related to human health. The objective of this study is to
investigate the effects of cold waves and heat waves on the mortality among the older adults (
>=65 years old) in the southeastern US from 2000 to 2018. We applied quasi-Poisson time-series
regression methods to examine the association between cold waves, heat waves and mortality
among the older adults. We obtained the impact of cold waves and heat waves on mortality in the
southeastern US and each state by calculating the risk ratio (RR). This study includes a total of
6,378,054 deaths of older adults in the southeastern US from 2000 to 2018. The study showed a
significant association between increased mortality and cold waves (RR=1.24, 95% CI: 1.22,
1.26) in the southeastern US, while the heat waves were not significantly associated with
increased elderly people’s mortality in the southeastern US (RR=0.71, 95% CI: 0.70, 0.72).
