Temperature frequency and mortality: Assessing adaptation to local temperature
Wu, Yao; Wen, Bo; Gasparrini, Antonio; Armstrong, Ben; Sera, Francesco; Lavigne, Eric; Li, Shanshan; Guo, Yuming; Overcenco, Ala; Urban, AlešAssessing the association between temperature frequency and mortality can provide insights into human adaptation to local ambient temperatures. We collected daily time-series data on mortality and temperature from 757 locations in 47 countries/regions during 1979–2020. We used a two-stage time series design to assess the association between temperature frequency and all-cause mortality. The results were pooled ...
Extreme Temperatures and Stroke Mortality: Evidence From a Multi-Country Analysis
Alahmad, Barrak; Khraishah, Haitham; Kamineni, Meghana; Royé, Dominic; Papatheodorou, Stefania I.; Vicedo-Cabrera, Ana Maria; Guo, Yuming; Lavigne, EricBackground: Extreme temperatures contribute significantly to global mortality. While previous studies on temperature and stroke-specific outcomes presented conflicting results, these studies were predominantly limited to single-city or single-country analyses. Their findings are difficult to synthesize due to variations in methodologies and exposure definitions. Methods: Within the Multi-Country Multi-City Netw...
All-cause, cardiovascular, and respiratory mortality and wildfire-related ozone...
Chen, Gongbo; Guo, Yuming; Yue, Xu; Xu, Rongbin; Yu,Wenhua; Ye, Tingting; Tong, Shilu; Gasparrini, Antonio; Bell,Michelle L.; Armstrong, BenBackground: Wildfire activity is an important source of tropospheric ozone (O3) pollution. However, no study to date has systematically examined the associations of wildfire-related O3 exposure with mortality globally. Methods: We did a multicountry two-stage time series analysis. From the Multi-City Multi-Country (MCC) Collaborative Research Network, data on daily all-cause, cardiovascular, and respiratory dea...
Ozone-related acute excess mortality projected to increase in the absence of cl...
Domingo, Nina G.G.; Fiore, Arlene M.; Lamarque, Jean-Francois; Kinney, Patrick L.; Jiang, Leiwen; Gasparrini, Antonio; Breitner, Susanne; Lavigne, EricShort-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...
Impact of population aging on future temperature-related mortality at different...
Chen, Kai; de Schrijver, Evan; Sivaraj, Sidharth; Sera, Francesco; Scovronick, Noah; Jiang, Leiwen; Roye, Dominic; Lavigne, Eric; Kyselý, JanOlder adults are generally amongst the most vulnerable to heat and cold. While temperature-related health impacts are projected to increase with global warming, the influence of population aging on these trends remains unclear. Here we show that at 1.5 °C, 2 °C, and 3 °C of global warming, heat-related mortality in 800 locations across 50 countries/areas will increase by 0.5%, 1.0%, and 2.5%, respectively; amon...
Global, regional, and national burden of mortality associated with cold spells ...
Gao, Yuan; Huang, Wenzhong; Zhao, Qi; Ryti, Niilo; Armstrong, Ben; Gasparrini, Antonio; Tong, Shilu; Pascal, Mathilde; Urban, Aleš; Zeka, ArianaBackground: Exposure to cold spells is associated with mortality. However, little is known about the global mortality burden of cold spells. Methods: A three-stage meta-analytical method was used to estimate the global mortality burden associated with cold spells by means of a time series dataset of 1960 locations across 59 countries (or regions). First, we fitted the location-specific, cold spell-related morta...
Associations Between Extreme Temperatures and Cardiovascular Cause-Specific Mor...
Alahmad, Barrak; Khraishah, Haitham; Royé, Dominic; Vicedo-Cabrera, Ana Maria; Guo, Yuming; Papatheodorou, Stefania I.; Achilleos, SouzanaBackground: Cardiovascular disease is the leading cause of death worldwide. Existing studies on the association between temperatures and cardiovascular deaths have been limited in geographic zones and have generally considered associations with total cardiovascular deaths rather than cause-specific cardiovascular deaths. Methods: We used unified data collection protocols within the Multi-Country Multi-City Collab...
Fluctuating temperature modifies heat-mortality association around the globe
Wu, Yao; Wen, Bo; Li, Shanshan; Gasparrini, Antonio; Tong, Shilu; Overcenco, Ala; Urban, Aleš; Schneider, Alexandra; Entezari, AlirezaStudies 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...
Comparison of weather station and climate reanalysis data for modelling tempera...
Mistry, Malcolm N.; Schneider, Rochelle; Masselot, Pierre; Royé, Dominic; Armstrong, Ben; Kyselý, Jan; Orru, Hans; Sera, Francesco; Tong, ShiluEpidemiological 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...
Geographical Variations of the Minimum Mortality Temperature at a Global Scale
Tobías, Aurelio; Hashizume, Masahiro; Honda, Yasushi; Sera, Francesco; Ng, Chris Fook Sheng; Kim, Yoonhee; Roye, Dominic; Chung, YeonseungBackground: Minimum mortality temperature (MMT) is an important indicator to assess the temperature-mortality association, indicating long-term adaptation to local climate. Limited evidence about the geographical variability of the MMT is available at a global scale. Methods: We collected data from 658 communities in 43 countries under different climates. We estimated temperature-mortality associations to deriv...
