儿童反复呼吸道感染与血清维生素D水平的关系

Children Recurrent Respiratory Tract Infections and the Levels of Serum Vitamin D

目的:探讨儿童反复呼吸道感染(RRI)与儿童期血清维生素D水平的关系。方法:随机选择2012年1-12月在我院儿科门诊或住院部诊治的儿童,按其血清维生素D水平分为三组:维生素D缺乏组、维生素D不足组和维生素D正常组,三组各150例,比较各组发生RRI的情况。结果:维生素D缺乏组发生RRI为49例,维生素D不足组为33例,维生素D正常组为21例,其中维生素D缺乏组与正常组比较,发生RRI的差异有统计学意义,维生素D不足组与正常组比较,发生RRI的差异无统计学意义。结论:儿童的维生素D水平与儿童期发生反复呼吸道感染密切相关,及时对维生素D缺乏或不足进行治疗,对儿童期发生RRI的减少有积极作用。

Objective：In order to explore the relationship between children’s recurrent respiratory infections（RRI） and the levels of serum vitamin D in childhood.Methods：Randomly selected pediatric outpatient or inpatient in our hospital from January to December,2012.According to the levels of serum vitamin D,they are divided into three groups： vitamin D deficiency group,vitamin D inadequate group and vitamin D normal group,each group obtains 150cases,compare the incidence rate of RRI between groups.Results：The RRI cases in vitamin D deficiency group are 49,33cases for vitamin D inadequate group,21cases for vitamin D normal group.Compared vitamin D deficiency group with normal group,RRI difference was statistically significant,compared vitamin D inadequate group with normal group,RRI difference was not statistical significance.Conclusion：Children’s vitamin D levels in childhood are closely related with RRI,taking timely manners to treat vitamin D deficiency or inadequate will produce positive effects on reducing RRI in childhood.
