Several studies worldwide have demonstrated significant relationships between meteorological parameters and stroke events. However, authors often reported discordant effects of both barometric pressure and air temperature on stroke occurrence. The present study investigated whether there was an association between weather parameters (barometric pressure and temperature) and ischemic stroke hospitalization. The aim of the study was to find out whether daily barometric pressure may be used as a prognostic variable to evaluate the workload change of a neurological intensive care unit. We conducted a retrospective review study in which we collected the independent (barometric pressure and temperature) and dependent variables (stroke hospitalization) every 24 h for the periods 10/1/2016-4/30/2017 at Augusta University Medical Center of Augusta, GA. We analyzed the data with zero-inflated Poisson model to assess the relationship between the barometric pressure, temperature, and daily stroke hospitalization. The results showed that there was a significantly correlation between daily barometric pressure variation and daily stroke hospitalization, especially on elder male patients (≥ 65). Stroke events were more likely to occur in the patients with risk factors than in those without risk factors when exposed to barometric pressure and temperature changes. Decreased barometric pressure and increased temperature were associated with increased daily stroke hospitalization. Furthermore, there was a potential delayed effect of increased stroke events after cold temperature exposure. Barometric pressure and temperature changes over the preceding 24 h are associated with daily stroke hospitalization. These findings may enhance our understanding of relationship between stroke and weather and maybe used in the development of public health strategies to minimize the weather-related stroke risk.
全球多项研究表明气象参数与中风事件之间存在显著关联。然而，作者们经常报告气压和气温对中风发生的影响不一致。本研究调查了天气参数（气压和温度）与缺血性中风住院之间是否存在关联。该研究的目的是确定每日气压是否可作为一个预后变量来评估神经重症监护病房的工作量变化。我们进行了一项回顾性研究，在佐治亚州奥古斯塔市奥古斯塔大学医学中心收集了2016年10月1日至2017年4月30日期间每24小时的自变量（气压和温度）和因变量（中风住院情况）。我们使用零膨胀泊松模型分析数据，以评估气压、温度与每日中风住院之间的关系。结果表明，每日气压变化与每日中风住院之间存在显著相关性，尤其是在老年男性患者（≥65岁）中。暴露于气压和温度变化时，有危险因素患者比无危险因素患者更易发生中风事件。气压降低和温度升高与每日中风住院增加相关。此外，低温暴露后中风事件增加存在潜在的延迟效应。前24小时的气压和温度变化与每日中风住院相关。这些发现可能会增进我们对中风与天气之间关系的理解，并可能用于制定公共卫生策略，以尽量降低与天气相关的中风风险。
