Seasonality of mortality under climate change: a multicountry projection study
Madaniyazi, L; Armstrong, B; Tobias, A; Mistry, MN; Bell, ML; Urban, A; Kyselý, J; Ryti, N; Cvijanovic, I; Ng, CFS; Roye, D; Vicedo-Cabrera, AM; Tong, SBackground: Climate change can directly impact temperature-related excess deaths and might subsequently change the seasonal variation in mortality. In this study, we aimed to provide a systematic and comprehensive assessment of potential future changes in the seasonal variation, or seasonality, of mortality across different climate zones. Methods: In this modelling study, we collected daily time series of mean ...
Ozone-related acute excess mortality projected to increase in the absence of cl...
Domingo, NGG; Fiore, AM; Lamarque, J-F; Kinney, PL; Jiang, L; Gasparrini, A; Breitner, S; Lavigne, E; Madureira, J; Masselot, P; Silva, SDNPDShort-term exposure to ground-level ozone in cities is associated with increased mortality and is expected to worsen with climate and emission changes. However, no study has yet comprehensively assessed future ozone-related acute mortality across diverse geographic areas, various climate scenarios, and using CMIP6 multi-model ensembles, limiting our knowledge on future changes in global ozone-related acute mort...
Global and Regional Cardiovascular Mortality Attributable to Nonoptimal Tempera...
Hundessa, S; Huang, W; Zhao, Q; Wu, Y; Wen, B; Alahmad, B; Armstrong, B; Gasparrini, A; Sera, F; Tong, S; Madureira, J; Kyselý, J; Schwartz, JBackground: The association between nonoptimal temperatures and cardiovascular mortality risk is recognized. However, a comprehensive global assessment of this burden is lacking. Objectives: The goal of this study was to assess global cardiovascular mortality burden attributable to nonoptimal temperatures and investigate spatiotemporal trends. Methods: Using daily cardiovascular deaths and temperature data from...
Regional variation in the role of humidity on city-level heat-related mortality
Guo, Q; Mistry, MN; Zhou, X; Zhao, G; Kino, K; Wen, B; Cvijanovic, I; Yoshimura, K; Satoh, Y; Kim, Y; Ng, CFS; Vicedo-Cabrera, AM; Armstrong, BThe rising humid heat is regarded as a severe threat to human survivability, but the proper integration of humid heat into heat-health alerts is still being explored. Using state-of-the-art epidemiological and climatological datasets, we examined the association between multiple heat stress indicators (HSIs) and daily human mortality in 739 cities worldwide. Notable differences were observed in the long-term tr...
Differential Mortality Risks Associated With PM2.5 Components A Multi-Country, ...
Masselot, P; Sera, F; Schneider, R; Kan, H; Lavigne, É; Stafoggia, M; Tobias, A; Chen, H; Burnett, RT; Schwartz, J; Zanobetti, A; Bell, ML; Chen, B-YBackground: The association between fine particulate matter (PM2.5) and mortality widely differs between as well as within countries. Differences in PM2.5 composition can play a role in modifying the effect estimates, but there is little evidence about which components have higher impacts on mortality. Methods: We applied a 2-stage analysis on data collected from 210 locations in 16 countries. In the first stag...
Comparison of weather station and climate reanalysis data for modelling tempera...
Mistry, MN; Schneider, R; Masselot, P; Royé, D; Armstrong, B; Kyselý, J; Orru, H; Sera, F; Tong, S; Lavigne, É; Urban, A; Madureira, J; García-León, DEpidemiological analyses of health risks associated with non-optimal temperature are traditionally based on ground observations from weather stations that offer limited spatial and temporal coverage. Climate reanalysis represents an alternative option that provide complete spatio-temporal exposure coverage, and yet are to be systematically explored for their suitability in assessing temperature-related health r...
Fluctuating temperature modifies heat-mortality association around the globe
Wu, Y; Wen, B; Li, S; Gasparrini, A; Tong, S; Overcenco, A; Urban, A; Schneider, A; Entezari, A; Vicedo-Cabrera, AM; Zanobetti, A; Analitis, A; Zeka, AStudies have investigated the effects of heat and temperature variability (TV) on mortality. However, few assessed whether TV modifies the heat-mortality association. Data on daily temperature and mortality in the warm season were collected from 717 locations across 36 countries. TV was calculated as the standard deviation of the average of the same and previous days’ minimum and maximum temperatures. We used l...
Global, regional, and national burden of mortality associated with short-term t...
Wu, Y; Li, S; Zhao, Q; Wen, B; Gasparrini, A; Tong, S; Overcenco, A; Urban, A; Schneider, A; Entezari, A; Vicedo-Cabrera, AM; Zanobetti, A; Analitis, ABackground: Increased mortality risk is associated with short-term temperature variability. However, to our knowledge, there has been no comprehensive assessment of the temperature variability-related mortality burden worldwide. In this study, using data from the MCC Collaborative Research Network, we first explored the association between temperature variability and mortality across 43 countries or regions. Th...
Mortality risk attributable to wildfire-related PM(2·5) pollution: a global tim...
Chen, G; Guo, Y; Yue, X; Tong, S; Gasparrini, A; Bell, ML; Armstrong, B; Schwartz, J; Jaakkola, JJK; Zanobetti, A; Lavigne, E; Nascimento Saldiva, PHBackground Many regions of the world are now facing more frequent and unprecedentedly large wildfires. However, the association between wildfire-related PM2·5 and mortality has not been well characterised. We aimed to comprehensively assess the association between short-term exposure to wildfire-related PM2·5 and mortality across various regions of the world. Methods For this time series study, data on daily co...

Zhao, Q; Guo, Y; Ye, T; Gasparrini, A; Tong, S; Overcenco, A; Urban, A; Schneider, A; Entezari, A; Vicedo-Cabrera, AM; Zanobetti, A; Analitis, ABackground: Exposure to cold or hot temperatures is associated with premature deaths. We aimed to evaluate the global, regional, and national mortality burden associated with non-optimal ambient temperatures. Methods: In this modelling study, we collected time-series data on mortality and ambient temperatures from 750 locations in 43 countries and five meta-predictors at a grid size of 0·5° × 0·5° across the gl...
