目的：确定不同年龄和性别的儿童哮喘患者的相邻日间温度变化（TVN）和医院就诊率之间的关系。研究设计：采用生态学设计探讨TVN对儿童哮喘患者医院就诊率的影响。一个Poisson广义线性回归模型与一个分布滞后非线性模型相结合，用线性模型分析TVN与儿童哮喘住院次数的关系。纳入了2010年6月至2013年7月的所有儿童哮喘医院访视（n = 17，022）。结果：在不同年龄和性别的儿童中，TVN与儿童哮喘的医院就诊次数有显著相关性。对于不同性别组，TVN对儿童哮喘的影响在男性和女性的3天和5天延迟时最大。对于不同年龄组，TVN对儿童哮喘的作用分别在0-4岁和5-14岁儿童中的1天和5天滞后时最大。TVN升高1 ℃与儿童哮喘住院率增加4.2%（95%置信区间0.9-7.6%）相关。结论：TVN与儿童哮喘住院率相关。一旦气温迅速变化，将促使监护人更加关注孩子的健康，这可能会降低儿童哮喘的发病率。(C)2016年皇家公共卫生学会。由爱思唯尔有限公司出版。保留所有权利。
Objectives: To identify the relationship between temperature variation between neighbouring days (TVN) and hospital visits for childhood asthma in age- and sex-specific groups.Study design: An ecological design was used to explore the effect of TVN on hospital visits for childhood asthma.Methods: A Poisson generalised linear regression model combined with a distributed lag non-linear model was used to analyse the association between TVN and hospital visits for childhood asthma. All hospital visits for childhood asthma from June 2010 to July 2013 were included (n = 17,022). Daily climate data were obtained from Hefei Meteorological Bureau.Results: A significant correlation was found between TVN and hospital visits for childhood asthma in age- and sex-specific groups. For different gender groups, the effect of TVN on childhood asthma was the greatest at 3 and 5 days lag for males and females. For different age groups, the effect of TVN on childhood asthma was the greatest at 1 and 5 days lag for 0-4 years and 5-14 years children, respectively. A 1 degrees C increase in TVN was associated with a 4.2% (95% confidence interval 0.9-7.6%) increase in hospital visits for childhood asthma.Conclusions: TVN is associated with hospital visits for childhood asthma. Once the temperature change rapidly, guardians will be urged to pay more attention to their children's health, which may reduce the morbidity of childhood asthma.
