Many studies have explored the relationship between short-term weather and its health effects (including pneumonia) based on mortality, although both morbidity and mortality pose a substantial burden. In this study, the authors aimed to describe the influence of meteorological factors on the number of emergency room (ER) visits due to pneumonia in Seoul, Korea.
Daily records of ER visits for pneumonia over a 6-year period (2009-2014) were collected from the National Emergency Department Information System. Corresponding meteorological data were obtained from the National Climate Data Service System. A generalized additive model was used to analyze the effects. The percent change in the relative risk of certain meteorological variables, including pneumonia temperature (defined as the change in average temperature from one day to the next), were estimated for specific age groups.
A total of 217 776 ER visits for pneumonia were identified. The additional risk associated with a 1°C increase in pneumonia temperature above the threshold of 6°C was 1.89 (95% confidence interval [CI], 1.37 to 2.61). Average temperature and diurnal temperature range, representing within-day temperature variance, showed protective effects of 0.07 (95% CI, 0.92 to 0.93) and 0.04 (95% CI, 0.94 to 0.98), respectively. However, in the elderly (65+ years), the effect of pneumonia temperature was inconclusive, and the directionality of the effects of average temperature and diurnal temperature range differed.
The term 'pneumonia temperature' is valid. Pneumonia temperature was associated with an increased risk of ER visits for pneumonia, while warm average temperatures and large diurnal temperature ranges showed protective effects.
许多研究基于死亡率探讨了短期天气与其健康影响（包括肺炎）之间的关系，尽管发病率和死亡率都带来了沉重负担。在本研究中，作者旨在描述气象因素对韩国首尔因肺炎而急诊就诊人数的影响。
从国家急诊科信息系统收集了6年期间（2009 - 2014年）因肺炎急诊就诊的每日记录。相应的气象数据来自国家气候数据服务系统。使用广义相加模型分析影响。针对特定年龄组估计了某些气象变量相对风险的百分比变化，包括肺炎温度（定义为相邻两天平均温度的变化）。
共确定了217776例因肺炎的急诊就诊病例。肺炎温度每升高1°C，高于6°C阈值时的额外风险为1.89（95%置信区间[CI]，1.37至2.61）。代表日内温度变化的平均温度和日较差分别显示出0.07（95%CI，0.92至0.93）和0.04（95%CI，0.94至0.98）的保护作用。然而，在老年人（65岁及以上）中，肺炎温度的影响尚无定论，平均温度和日较差的影响方向不同。
“肺炎温度”这一术语是有效的。肺炎温度与因肺炎急诊就诊风险增加相关，而温暖的平均温度和较大的日较差显示出保护作用。
