We examined if croup presentations to the emergency department (ED) were associated with weather changes in a warm temperate climate. We collected data on all 729 cases with an ED discharge or admission diagnosis of croup over a 798 day time period. We obtained detailed climatic records from the New South Wales Meteorological Office for the same time period. Only one daily variable, ground temperature at 9:00, was significantly associated with the number of croup attendances (linear regression -0.2062; 95% CI -0.272 to -0.138). There was a stronger correlation (-0.426; 95% CI -0.684 to -0.072) between the calculated mean monthly temperature and the monthly number of croup admissions. Even in this milder climate, croup is associated with cooler weather. We are unable to conclude that hospital attendances for croup are caused by changes in temperature alone, as other factors such as the prevalence of viral illness also follow a seasonal, and therefore, temperature-related pattern.
我们研究了在温暖的温带气候中，急诊科（ED）就诊的喘鸣是否与天气变化有关。我们收集了在 798 天的时间内，所有 729 例 ED 出院或入院诊断为喘鸣的病例的数据。我们从新南威尔士州气象局获得了同一时期的详细气候记录。只有一个日变量，即 9:00 的地面温度，与喘鸣就诊人数显著相关（线性回归-0.2062；95%置信区间-0.272 至-0.138）。计算得出的月平均温度与每月喘鸣入院人数之间的相关性更强（-0.426；95%置信区间-0.684 至-0.072）。即使在这种气候较温和的情况下，喘鸣也与较冷的天气有关。我们无法得出结论，喘鸣的住院就诊仅仅是由于温度变化引起的，因为其他因素，如病毒感染的流行，也遵循季节性和因此与温度相关的模式。
