Abstract:
Objective To investigate the control status of bronchial asthma(referred to as"asthma")in school-age children with normal pulmonary ventilation function and the occurrence of acute attacks within 1 year of follow-up.Methods A retrospective analysis was conducted on clinical data of 327 children aged 6-14 years with bronchial asthma and normal pulmonary ventilation function from April to September 2021.Based on the measured value of one second rate(FEV1/FVC),the children were divided into the ≥80％group(267 cases)and the＜80％group(60 cases).The pulmonary ventilation function,asthma control level,and occurrence of acute attacks within 1 year were compared between the two groups.Results The baseline pulmonary ventilation function in the＜80％group was lower than that in the ≥80％group,and the proportion of small airway dysfunction was higher than that in the ≥80％group(P＜0.05).After standardized treatment for 1 year,the small airway function indices in the＜80％group improved but remained lower than those in the ≥80％group(P＜0.05).The rate of incomplete asthma control at baseline was 34.6％(113/327),and the asthma control level in the＜80％group was lower than that in the ≥80％group(P＜0.05).After standardized treatment for 1 year,the asthma control level in the＜80％group remained lower than that in the ≥80％group,and the proportion of acute asthma attacks was higher than that in the ≥80％group(P＜0.05).Conclusions Approximately one-third of school-age children with asthma still have incomplete asthma control when their pulmonary ventilation function is normal.Among them,children with measured FEV1/FVC＜80％have an increased risk of acute asthma attacks and require close follow-up and strengthened asthma management.
