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...
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....
<h2>Summary</h2><h3>Background</h3> The health impacts of climate warming are usually quantified based on daily average temperatures. However, extra risks might result from hot nights. We project the future mortality burden due to <h3>Methods</h3> selected night excess (HNE) represent intensity night-time heat, which was calculated as sum high temperature during time. collected historical data in 28 cities three east Asian countries, 1981 2010. associations between HNE and each city were...
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...
Evidence on the potential interactive effects of heat and ambient air pollution cause-specific mortality is inconclusive limited to selected locations.We investigated cardiovascular respiratory its modification by during summer months (six consecutive hottest months) in 482 locations across 24 countries.Location-specific daily death counts exposure data (e.g., particulate matter with diameters ≤ 2.5 µm [PM2.5]) were obtained from 2000 2018. We used location-specific confounder-adjusted...
Older adults are generally amongst the most vulnerable to heat and cold. While temperature-related health impacts projected increase with global warming, influence of population aging on these trends remains unclear. Here we show that at 1.5 °C, 2 3 °C heat-related mortality in 800 locations across 50 countries/areas will by 0.5%, 1.0%, 2.5%, respectively; among which 1 5 4 deaths can be attributed aging. Despite a decrease cold-related due progressive warming alone, mostly counteract this...
Abstract Heatwaves are commonly simplified as binary variables in epidemiological studies, limiting the understanding of heatwave-mortality associations. Here we conduct a multi-country study across 28 East Asian cities that employed Cumulative Excess Heatwave Index (CEHWI), which represents excess heat accumulation during heatwaves, to explore potentially nonlinear associations daytime-only, nighttime-only, and day-night compound heatwaves with mortality from 1981 2010. Populations...
Various retrospective studies have reported on the increase of mortality risk due to higher diurnal temperature range (DTR). This study projects effect DTR future across 445 communities in 20 countries and regions.DTR-related was estimated basis historical daily time-series weather factors from Jan 1, 1985, Dec 31, 2015, with data for regions, Multi-Country Multi-City Collaborative Research Network. We obtained projected series associated four climate change scenarios, using representative...
Abstract There is conflicting evidence on the influence of weather COVID-19 transmission. Our aim to estimate weather-dependent signatures in early phase pandemic, while controlling for socio-economic factors and non-pharmaceutical interventions. We identify a modest non-linear association between mean temperature effective reproduction number (R e ) 409 cities 26 countries, with decrease 0.087 (95% CI: 0.025; 0.148) 10 °C increase. Early interventions have greater effect R 0.285 CI 0.223;...
Epidemiological evidence on short-term association between ambient carbon monoxide (CO) and mortality is inconclusive limited to single cities, regions, or countries. Generalisation of results from previous studies hindered by potential publication bias different modelling approaches. We therefore assessed the exposure CO daily in a multicity, multicountry setting.We collected data air pollution, meteorology, total 337 cities 18 countries covering various periods 1979 2016. All included had...
Minimum mortality temperature (MMT) is an important indicator to assess the temperature-mortality association, indicating long-term adaptation local climate. Limited evidence about geographical variability of MMT available at a global scale.We collected data from 658 communities in 43 countries under different climates. We estimated associations derive for each community using Poisson regression with distributed lag nonlinear models. investigated variation by climatic zone mixed-effects...
BackgroundIncreased mortality risk is associated with short-term temperature variability. However, to our knowledge, there has been no comprehensive assessment of the variability-related burden worldwide. In this study, using data from MCC Collaborative Research Network, we first explored association between variability and across 43 countries or regions. Then, provide a more picture global variability, gridded resolution 0·5° × were used assess at global, regional, national levels....
Suicide is a serious worldwide public health concern, and South Korea has shown the highest suicide rate among Organisation for Economic Co-operation Development (OECD) countries since 2003. Nevertheless, most previous Korean studies on had limitations in investigating various social environment factors using long-term nationwide data. Thus, this study examined how characteristics are related to at district-level, longitudinal data over 11 years.We used district-level age-standardized total...
Identifying how greenspace impacts the temperature-mortality relationship in urban environments is crucial, especially given climate change and rapid urbanization. However, effect modification of on heat-related mortality has been typically focused a localized area or single country. This study examined heat-mortality among different levels global setting.
Background: Recent studies have reported the association between air pollution exposure and reduced kidney function. However, it is unclear whether associated with an increased risk of acute injury (AKI). Objectives: To address this gap in knowledge, we investigated effect estimates long-term exposures to fine particulate matter [PM ≤2.5μm aerodynamic diameter (PM2.5)], nitrogen dioxide (NO2), ozone (O3) on first hospital admission for AKI using nationwide Medicare data. Methods: This...
BackgroundClimate change can directly impact temperature-related excess deaths and might subsequently the seasonal variation in mortality. In this study, we aimed to provide a systematic comprehensive assessment of potential future changes variation, or seasonality, mortality across different climate zones.MethodsIn modelling collected daily time series mean temperature (all causes non-external only) via Multi-Country Multi-City Collaborative (MCC) Research Network. These data were during...
