Association between cold waves, heat waves and mortality among the older adults in the southeastern US (2000 to 2018) Open Access

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).
