目的探讨小儿反复呼吸道感染(RRI)与维生素D缺乏亚临床状态的关系。方法 210例体检婴幼儿作为研究对象,以70例维生素D正常婴幼儿作为正常组,以70例维生素D不足婴幼儿作为不足组,以70例维生素D缺乏婴幼儿作为缺乏组,对比三组应婴幼儿的RRI发生率。结果不足组与缺乏组患儿的RRI发生率(24.29%、34.29%)明显高于正常组(12.86%),差异具有统计学意义(P<0.05)。缺乏组RRI的发生率(24.29%)明显高于不足组(34.29%),差异具有统计学意义(P<0.05)。结论维生素D缺乏与小儿反复呼吸道感染之间具有密切关系,进行针对性治疗可有效改善患儿的临床症状,降低该病的发病率,值得推广。
Objective To investigate the relationship between children with recurrent respiratory tract infection (RRI) and subclinical vitamin D deficiency. Methods A total of 210 infants with physical examinations of vitamin D were selected as normal subjects and 70 infants with inadequate vitamin D as infants, and 70 infants with vitamin D deficiency as control subjects. RRI incidence in infants and young children. Results The incidence of RRI (24.29%, 34.29%) was significantly higher in the under-and under-treatment group than in the normal group (12.86%). The difference was statistically significant (P <0.05). The incidence of RRI in the lacking group (24.29%) was significantly higher than that in the deficient group (34.29%), the difference was statistically significant (P <0.05). Conclusion There is a close relationship between vitamin D deficiency and recurrent respiratory tract infections in children. Targeted treatment can effectively improve the clinical symptoms of children and reduce the incidence of the disease, which is worth promoting.
