“…In comparison with prior studies conducted in Yunnan Province, our research revealed that cardiovascular disease is also affected by daily temperature changes [32]. This discovery contributes to a more nuanced understanding of the interplay between meteorological factors and cardiovascular as well as cerebrovascular disease, offering valuable insights for preventing and managing these health issues.…”

“…Thus, the province is an ideal place to study the spatial heterogeneity of its different cities. Our previous studies examined the association between temperature exposure and YLL in several cities of Yunnan Province but did not investigate spatial heterogeneity because of lack of data from eastern, northern, and central cities [ 32 33 ].…”

Background:The relationship between climate change and human health has become one of the major worldwide public health issues.Objective: This study evaluated the effect of ambient temperature on the mortality burden of non-accidental deaths in Yunnan Province and further explored its spatial heterogeneity among different regions. Methods:We collected mortality and meteorological data from all 129 counties in Yunnan Province from 2014 to 2020, and 16 prefecture-level cities were analyzed as units. A distributed lagged nonlinear model was utilized to estimate the effect of temperature exposure on years of life lost (YLL) for non-accidental deaths in each prefecture-level city. The effect of ambient temperature on the total attributable fraction (AF) for death was calculated. A multivariate meta-analysis was applied to obtain an overall aggregated estimate of effects and spatial heterogeneity among 16 prefecture-level cities was evaluated by adjusting the city-specific geographical characteristics, demographic characteristics, economic factors, and health resources factors. Results:The temperature-YLL association was nonlinear and followed slide-shaped curves in all regions. The cumulative extreme cold and mild cold effects along lag 0-21 days on YLL due to non-accidental deaths were 166.96 (95% empirical confidence interval [eCI] 45.76-288.17) and 47.57 (95% eCI 3.58-91.55), respectively. The AF for non-accidental deaths due to daily mean temperature was 5.99% (95% eCI 3.15-8.37). Cold temperature was responsible for most of the mortality burden (4.29% [95% eCI 2.78-5.67]), while the burden due to heat was low and non-significant. The vulnerable subpopulations include males, age <75, farmers, ethnic minorities, and patients with cardiovascular or respiratory diseases. Moreover, 48.2% heterogeneity in the effect of mean temperature on YLL was found after considering the inherent characteristics of the 16 prefecture-level cities.Conclusions: This study suggests that the cold effect dominated the total effect of temperature on mortality burden, and its effect was heterogeneous among different regions, which provides a basis for spatial planning and health policy formulation for disease prevention.

“…Besides extreme temperatures, exposure to moderately high or low temperatures has been found to negatively affect public health e.g., [11][12][13][14][15]. In addition, recent studies demonstrated the adverse health effects of variable temperature, using indicators such as the diurnal temperature range [16][17][18][19] and the temperature variability (i.e., the standard deviation of minimum and maximum temperatures during a given time period) [20,21].…”

It is well-established that exposure to non-optimum temperatures adversely affects public health, with the negative impact varying with latitude, as well as various climatic and population characteristics. This work aims to assess the relationship between ambient temperature and mortality from cardiorespiratory diseases in Eastern Macedonia and Thrace, in Northern Greece. For this, a standard time-series over-dispersed Poisson regression was fit, along with a distributed lag nonlinear model (DLNM), using a maximum lag of 21 days, to capture the non-linear and delayed temperature-related effects. A U-shaped relationship was found between temperature and cardiorespiratory mortality for the overall population and various subgroups and the minimum mortality temperature was observed around the 65th percentile of the temperature distribution. Exposure to extremely high temperatures was found to put the highest risk of cardiorespiratory mortality in all cases, except for females which were found to be more sensitive to extreme cold. It is remarkable that the highest burden of temperature-related mortality was attributed to moderate temperatures and primarily to moderate cold. The elderly were found to be particularly susceptible to both cold and hot thermal stress. These results provide new evidence on the health response of the population to low and high temperatures and could be useful to local authorities and policy-makers for developing interventions and prevention strategies for reducing the adverse impact of ambient temperature.
