: Numerous epidemiological studies have reported relevance of morbidity and mortality from cardiovascular diseases with short-term exposure to environmental temperature. In this study, we examined the hypothesis between temperature indices and hospital admission because of cardiovascular diseases. : The daily number of CVDs was obtained from all hospitals of the Sabzevar city. A semi-parametric generalized additive model (GAM) following a quasi-Poisson distribution with distributed lag non-linear model (dlnm) was selected as a modeling framework for time-series analysis. : The overall CVD risk comparing the 1st percentile and the 99th percentile relative to the mean temperature (at lag 0) was 1.33 (95% CI, 1.11: 1.61), and 1.34 (95% CI, 1.10: 1.64), respectively. For all indicators, the extremely cold effects persisted for the initial 7 days. : Our results suggest that extremely cold and extremely hot temperatures increase the relative risk of cardiovascular diseases.
大量流行病学研究报告称，短期暴露于环境温度与心血管疾病的发病率和死亡率有关。在这项研究中，我们检验了温度指数与心血管疾病住院之间的假设。
我们从萨布泽瓦尔市的所有医院获得了每日心血管疾病（CVD）的数量。采用带有分布滞后非线性模型（dlnm）的拟泊松分布的半参数广义加性模型（GAM）作为时间序列分析的建模框架。
与平均温度（滞后 0）相比，第 1 百分位和第 99 百分位的整体 CVD 风险分别为 1.33（95%CI，1.11:1.61）和 1.34（95%CI，1.10:1.64）。对于所有指标，极寒效应持续最初的 7 天。
我们的结果表明，极寒和极热天气会增加心血管疾病的相对风险。
