Abstract

This study assessed the impact of various temperature indices, including mean temperature (MT), diurnal temperature range (DTR), and temperature changes between neighboring days (TCN) on hospitalization rates for cardiovascular system diseases among residents of Zhangye City, a typical western city in China. The Quasi-Poisson generalized additive regression model (GAM) in conjunction with a distributed lag nonlinear model (DLNM) was applied to estimate the association of temperature indices with CVD hospitalization rates in Zhangye City during the periods of 2015-2021. The exposure-response relationship and relative risk were discussed and stratified analyses by age and gender were conducted. We found that the hospitalization rates of cardiovascular disease (CVD) patients in Zhangye City was significantly related to different temperature indicators (MT, DTR, TCN). Both low and high MT, DTR, and TCN increased the risk of cardiovascular disease (CVD) among residents. Besides, different demographic populations exhibited distinct sensitivities to temperature conditions. Relevant authorities should devise corresponding preventive and control measures to protect vulnerable populations.

各种温度指标对中国张掖市心血管疾病患者住院治疗的影响。

本研究评估了各种气温指数（包括平均气温（MT）、昼夜温差（DTR）和相邻日气温变化（TCN））对中国典型西部城市张掖市居民心血管系统疾病住院率的影响。应用准泊松广义加性回归模型（GAM）结合分布滞后非线性模型（DLNM）估算了2015-2021年间张掖市气温指数与心血管病住院率的关系。讨论了暴露-反应关系和相对风险，并按年龄和性别进行了分层分析。我们发现，张掖市心血管疾病（CVD）患者的住院率与不同温度指标（MT、DTR、TCN）显著相关。低和高的MT、DTR和TCN都会增加居民罹患心血管疾病（CVD）的风险。此外，不同人群对温度条件的敏感性也不同。相关部门应制定相应的防控措施，保护易感人群。

期刊介绍： The Journal publishes original research papers, review articles and short communications on studies examining the interactions between living organisms and factors of the natural and artificial atmospheric environment. Living organisms extend from single cell organisms, to plants and animals, including humans. The atmospheric environment includes climate and weather, electromagnetic radiation, and chemical and biological pollutants. The journal embraces basic and applied research and practical aspects such as living conditions, agriculture, forestry, and health. The journal is published for the International Society of Biometeorology, and most membership categories include a subscription to the Journal.
