Seasonal characteristics of pediatric asthma in Hohhot analyzed with concentration and circular distribution methods

目的:探讨儿童哮喘的易发年龄以及不同年龄段儿童哮喘的发病高峰期,为预防和减少儿童哮喘发病提供理论依据。方法:基于Excel建立儿童哮喘就诊人数数据库,采用集中度与应用圆形分布法对呼和浩特市2010-2019年儿童哮喘就诊人数进行统计分析。结果:学龄前期为儿童哮喘的易发年龄,尤以4岁最多;儿童哮喘多发于8、9月;呼和浩特市2010-2019年儿童哮喘发病高峰日为8月7日,发病高峰期为4月25日-11月19日。其中,婴幼儿期、学龄前期、学龄期的发病高峰日分别是7月6日、7月31日、8月25日,学龄期儿童季节性更强。结论:儿童哮喘具有季节性规律,在预防工作中应充分考虑其发病的季节特点,开展针对性的防控措施。
