Heat exposure and self-rated health in older Chinese adults: the mediating roles of chronic disease and intergenerational support, 2008-2018 CLHLS.

ABSTRACT:

Background

Under the dual pressures of global warming and accelerated population aging, rising temperatures pose a particularly serious threat to the older population. However, systematic evidence on the heat exposure-response pathway is still scarce. This study aims to explore the effects of heat exposure on self-rated health and its pathways in older adults in China. We predicted that heat exposure would reduce the self-rated health of older adults, and that chronic diseases and intergenerational support would mediate this effect.

Methods

We linked health data from 9,670 participants in the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2008-2018 waves) with meteorological records from the National Climatic Data Center (NCDC). Individual fixed-effects models were em
