BackgroundAlthough studies have provided estimates of premature deaths attributable to either heat or cold in selected countries, none has so far offered a systematic assessment across the whole temperature range populations exposed different climates. We aimed quantify total mortality burden non-optimum ambient temperature, and relative contributions from moderate extreme temperatures.MethodsWe collected data for 384 locations Australia, Brazil, Canada, China, Italy, Japan, South Korea,...
The systematic evaluation of the results time-series studies air pollution is challenged by differences in model specification and publication bias.We evaluated associations inhalable particulate matter (PM) with an aerodynamic diameter 10 μm or less (PM10) fine PM 2.5 (PM2.5) daily all-cause, cardiovascular, respiratory mortality across multiple countries regions. Daily data on were collected from 652 cities 24 We used overdispersed generalized additive models random-effects meta-analysis...
Climate change can directly affect human health by varying exposure to non-optimal outdoor temperature. However, evidence on this direct impact at a global scale is limited, mainly due issues in modelling and projecting complex highly heterogeneous epidemiological relationships across different populations climates.We collected observed daily time series of mean temperature mortality counts for all causes or non-external only, periods ranging from Jan 1, 1984, Dec 31, 2015, various locations...
BackgroundExposure to cold or hot temperatures is associated with premature deaths. We aimed evaluate the global, regional, and national mortality burden non-optimal ambient temperatures.MethodsIn this modelling study, we collected time-series data on from 750 locations in 43 countries five meta-predictors at a grid size of 0·5° × across globe. A three-stage analysis strategy was used. First, temperature–mortality association fitted for each location by use regression. Second, multivariate...
Background: Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available variation associations between and multiple countries, analyzed simultaneously. Methods: We obtained daily data 306 communities from 12 countries/regions (Australia, Brazil, Thailand, China, Taiwan, Korea, Japan, Italy, Spain, United Kingdom, States, Canada). Two-stage analyses were used to assess nonlinear delayed relation mortality. In first...

Background Heatwaves are a critical public health problem. There will be an increase in the frequency and severity of heatwaves under changing climate. However, evidence about impacts climate change on heatwave-related mortality at global scale is limited. Methods findings We collected historical daily time series mean temperature for all causes or nonexternal causes, periods ranging from January 1, 1984, to December 31, 2015, 412 communities within 20 countries/regions. estimated...
The evidence and method are limited for the associations between mortality temperature variability (TV) within or days.We developed a novel to calculate TV investigated TV-mortality using large multicountry data set.We collected daily from 372 locations in 12 countries/regions (Australia, Brazil, Canada, China, Japan, Moldova, South Korea, Spain, Taiwan, Thailand, United Kingdom, States). We calculated standard deviation of minimum maximum temperatures during exposure days. Two-stage...
The health burden associated with temperature is expected to increase due a warming climate. Populations living in cities are likely be particularly at risk, but the role of urban characteristics modifying direct effects on still unclear. In this contribution, we used multi-country dataset study effect modification temperature-mortality relationships by range city-specific indicators.We collected ambient and mortality daily time-series data for 340 22 countries, periods between 1985 2014....

Cardiovascular disease is the leading cause of death worldwide. Existing studies on association between temperatures and cardiovascular deaths have been limited in geographic zones generally considered associations with total rather than cause-specific deaths.We used unified data collection protocols within Multi-Country Multi-City Collaborative Network to assemble a database daily counts specific causes from 567 cities 27 countries across 5 continents overlapping periods ranging 1979 2019....
Previous literature suggests that higher ambient temperature may play a role in increasing the risk of suicide. However, no multi-country study has explored shape association and moderate extreme heat across different locations.
Background: There is strong experimental evidence that physiologic stress from high temperatures greater if humidity higher. However, heat indices developed to allow for this have not consistently predicted mortality better than dry-bulb temperature. Objectives: We aimed clarify the potential contribution of an addition temperature in predicting daily summer by using a large multicountry dataset. Methods: In 445 cities 24 countries, we fit time-series regression model with distributed lag...
Abstract Epidemiological 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 provide complete spatio-temporal exposure coverage, yet to be systematically explored for their suitability in assessing temperature-related at a global scale. Here we the first comprehensive analysis over multiple regions assess most...
Heat-related mortality has been identified as one of the key climate extremes posing a risk to human health. Current research focuses largely on how heat increases with mean global temperature rise, but it is unclear much change will increase frequency and severity extreme summer seasons high impact In this probabilistic analysis, we combined empirical heat-mortality relationships for 748 locations from 47 countries model large ensemble data identify probable past future highly impactful...
