Heat Wave and Mortality: A Multicountry, Multicommunity Study.

ABSTRACT:

Background

Few studies have examined variation in the associations between heat waves and mortality in an international context.

Objectives

We aimed to systematically examine the impacts of heat waves on mortality with lag effects internationally.

Methods

We collected daily data of temperature and mortality from 400 communities in 18 countries/regions and defined 12 types of heat waves by combining community-specific daily mean temperature ≥90th, 92.5th, 95th, and 97.5th percentiles of temperature with duration ≥2, 3, and 4 d. We used time-series analyses to estimate the community-specific heat wave-mortality relation over lags of 0-10 d. Then, we applied meta-analysis to pool heat wave effects at the country level for cumulative and lag effects for each type of heat
