维生素A水平与婴幼儿呼吸道感染相关性研究

Correlation between Vitamin A Level and Infantile Respiratory Tract Infection

目的探讨维生素A水平与婴幼儿呼吸道感染的相关性。方法方便选取2017年5—12月期间于该院住院的呼吸道感染患儿314例婴幼儿为研究对象,全部小儿均抽取静脉血液样本测定血红蛋白及血维生素A水平,观察不同年龄小儿血维生素水平差异性以及血维生素水平同呼吸道感染和血红蛋白间的关系。结果 0~1岁小儿血维生素A可疑缺乏55.20%,亚临床缺乏10.42,%,与1~2岁和2~3岁小儿比较差异有统计学意义(χ~2=4.52,3.91,4.08,4.25,P<0.05)。反复感染组小儿血维生素A可疑缺乏52.78%,亚临床缺乏52.78%,与感染组比较差异有统计学意义(χ~2=3.58,10.92,P<0.05)。结论婴幼儿维生素A缺乏与呼吸道感染疾病发生密切相关,通常维生素A缺乏越严重,小儿呼吸道感染概率越高,感染次数越多,应引起临床重视。

Objective This paper tries to investigate the correlation between vitamin A level and respiratory tract infection in infants. Methods A total of 314 infants and children with respiratory tract infections who were hospitalized in this hospital between May and December 2017 were conveniently selected as the study subjects. All children were sampled for venous blood samples to determine hemoglobin and blood vitamin A levels. Differences in vitamin levels and blood vitamin levels with the relationship between respiratory infections and hemoglobin. Results The susceptibility of vitamin A in children aged 0-1 years was 55.20%, subclinical deficiency was 10.42%, and there were statistical differences between children aged 1-2 and 2-3（χ2=4.52,3.91,4.08,4.25,P〈0.05）. Repeated infection group of children with vitamin A suspected lack of 52.78%, subclinical lack of 52.78%, compared with the infection group was statistically significant（χ2=3.58,10.92, P〈0.05）. Conclusion Vitamin A deficiency in infants is closely related to respiratory tract infections. The more severe vitamin A deficiency is, the higher the probability of respiratory infection and the more infection times, the more attention should be paid to.
