Association between Cold Spells and Mortality Risk and Burden: A Nationwide Study in China.

ABSTRACT:

Background

Few multicity studies have evaluated the association between cold spells and mortality risk and burden.

Objectives

We aimed to estimate the association between cold spells and cause-specific mortality and to evaluate the mortality burden in China.

Methods

We conducted a time-series analysis with a nationally representative Disease Surveillance Points System database during the cool seasons spanning from 2013 to 2015 in 272 Chinese cities. We used 12 cold-spell definitions and overdispersed generalized additive models with distributed lag models to estimate the city-specific cumulative association of cold spells over lags of 0-28 d. We controlled for the nonlinear and lagged effects of cold temperature over 0-28 d to evaluate the added effect estimates of co
