目的探讨呼吸道感染（RTI）急诊就诊与昼夜温差（DTR）的关系，一个与城市化和全球气候变化密切相关的天气参数。方法我们进行了半参数时间序列分析，以估计调整日常天气条件后，与DTR变化相关的RTI急诊室就诊的百分比增加结果DTR与RTI的每日急诊就诊次数显著相关。当日DTR（L0）和2日DTR移动平均值（L01）每增加1 C，RTI急诊就诊率分别增加0.94%（95%CI，0.34%~ 1.55%）和2.08%（95%CI，1.24%~ 2.93%）。需要更多的研究来了解DTR对呼吸系统健康的影响。
Objective This study aimed to assess the association between emergency-room visits for respiratory tract infection (RTI) with diurnal temperature range (DTR), a weather parameter closely associated with urbanization and global climate change.Methods We conducted a semiparametric time-series analysis to estimate the percentage increase in emergency-room visits for RTI associated with changes in DTR after adjustment for daily weather conditions (temperature and relative humidity) and outdoor air pollution.Results DTR was significantly associated with daily emergency-room visits for RTI. An increase of 1 C in the current-day (L0) and in the 2-day moving average (L01) DTR corresponded to a 0.94% [95% confidence interval (CI), 0.34%-1.55%] and 2.08% (95% CI, 1.24%-2.93%) increase in emergency-room visits for RTI, respectively.Conclusion DTR was associated with increased risk of RTI. More studies are needed to understand the impact of DTR on respiratory health.
