Climate change is one of the biggest health threats of the 21st century.Although China is the biggest developing country,with a large population and different climate types,its projections of large-scale heat-related excess mortality remain understudied.In particular,the effects of climate change on aging populations have not been well studied,and may result in significantly underestimation of heat effects.In this study,we took four climate change scenarios of Tier-1 in CMIP6,which were combinations of Shared Socioeconomic Pathways(SSPs)and Representative Concentration Pathways(RCPs).We used the exposure-response functions derived from previous studies combined with baseline age-specific non-accidental mortality rates to project heat-related excess mortality.Then,we employed the Logarithmic Mean Divisia Index(LMDI)method to decompose the impacts of climate change,population growth,and aging on heat-related excess mortality.Finally,we multiplied the heat-related Years of Life Lost(YLL)with the Value of a Statistical Life Year(VSLY)to quantify the economic burden of premature mortality.We found that the heat-related excess mortality would be concentrated in central China and in the densely populated south-eastern coastal regions.When aging is considered,heat-related excess mortality will become 2.8–6.7 times than that without considering aging in 2081–2100 under different scenarios.The contribution analysis showed that the effect of aging on heat-related deaths would be much higher than that of climate change.Our findings highlighted that aging would lead to a severe increase of heat-related deaths and suggesting that regional-specific policies should be formulated in response to heat-related risks. 展开更多

Communities play a crucial role in protecting the health of vulnerable populations such as the elderly,low-income groups,and high-risk individuals during cold spells.However,current strategies for responding to cold spells primarily consist of programmatic policies that lack practicality,specificity,and detailed implementation guidelines for community workers.Therefore,this study aims to identify and analyze the challenges faced by communities in responding to cold spells,review international experiences,and develop a set of practical checklists for community-level health protection.These checklists will assist community workers and volunteers in effectively preparing for,responding to,and recovering from cold spells. 展开更多
