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...
Differential Mortality Risks Associated With PM2.5 Components: A Multi-Country,...
Masselot, Pierre; Sera, Francesco; Schneider, Rochelle; Kan, Haidong; Lavigne, Éric; Stafoggia, Massimo; Tobias, Aurelio; Chen, HongBackground: 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...
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...
Ambient carbon monoxide and daily mortality: a global time-series study in 337 ...
Chen, Kai; Breitner, Susanne; Wolf, Kathrin; Stafoggia, Massimo; Sera, Francesco; Vicedo-Cabrera, Ana M.; Guo, Yuming; Tong, Shilu; Lavigne, EricBackground: Epidemiological evidence on short-term association between ambient carbon monoxide (CO) and mortality is inconclusive and limited to single cities, regions, or countries. Generalisation of results from previous studies is hindered by potential publication bias and different modelling approaches. We therefore assessed the association between short-term exposure to ambient CO and daily mortality in a ...
Projections of excess mortality related to diurnal temperature range under clim...
Lee, Whanhee; Kim, Yoonhee; Sera, Francesco; Gasparrini, Antonio; Park, Rokjin; Michelle Choi, Hayon; Prifti, Kristi; Bell, Michelle L.Background: Various retrospective studies have reported on the increase of mortality risk due to higher diurnal temperature range (DTR). This study projects the effect of DTR on future mortality across 445 communities in 20 countries and regions. Methods: DTR-related mortality risk was estimated on the basis of the historical daily time-series of mortality and weather factors from Jan 1, 1985, to Dec 31, 2015, ...
Short term association between ozone and mortality: global two stage time serie...
Vicedo-Cabrera, Ana M.; Sera, Francesco; Liu, Cong; Armstrong, Ben; Milojevic, A.i.; Guo, Yuming; Tong, Shilu; Lavigne, Eric; Kyselý, Jan; Urban, AlešObjective: To assess short term mortality risks and excess mortality associated with exposure to ozone in several cities worldwide. Design: Two stage time series analysis. Setting: 406 cities in 20 countries, with overlapping periods between 1985 and 2015, collected from the database of Multi-City Multi-Country Collaborative Research Network. Population: Deaths for all causes or for external causes only registe...
Ambient particulate air pollution and daily mortality in 652 cities
Liu, Cong; Chen, Renjie; Sera, Francesco; Vicedo-Cabrera, Ana M.; Guo, Yuming; Tong, Shilu; Coelho, Micheline S.Z.S.; Saldiva, Paulo H.N.; Lavigne, EricThe systematic evaluation of the results of time-series studies of air pollution is challenged by differences in model specification and publication bias. We evaluated the associations of inhalable particulate matter (PM) with an aerodynamic diameter of 10 μm or less (PM10) and fine PM with an aerodynamic diameter of 2.5 μm or less (PM2.5) with daily all-cause, cardiovascular, and respiratory mortality across m...
Predicted temperature-increase-induced global health burden and its regional va...
Lee, Jae Young; Kim, Ho; Gasparrini, Antonio; Armstrong, Ben; Bell, Michelle L.; Sera, Francesco; Lavigne, Eric; Abrutzky, Rosana; Tong, ShiluAn increase in the global health burden of temperature was projected for 459 locations in 28 countries worldwide under four representative concentration pathway scenarios until 2099. We determined that the amount of temperature increase for each 100 ppm increase in global CO2 concentrations is nearly constant, regardless of climate scenarios. The overall average temperature increase during 2010-2099 is largest ...
