ObjectivesAllergic rhinitis (AR) and asthma often occur concomitantly and are the two most common inflammatory conditions of the airways in children. Large-scale studies investigating the comorbidity of asthma and AR in children are rare. So, we performed a meta-analysis to describe the comorbidity rate of asthma and AR in Chinese children.MethodsWe retrieved related studies from Pubmed, Science, Springer, Elsevier, Embase, BMJ, and four Chinese biomedical databases, including Wanfang Data, VIP, CBM, and CNKI. From these individual studies, the comorbidity rate of asthma and AR in Chinese children was extracted and pooled to generate summary effect estimates in R version 3.2.3.ResultsThe meta-analysis included 25 cross-sectional studies. The results indicated that in China, the incidence of asthma in children with AR is 35.01% (95% CI: 32.32%–37.70%) and the incidence of AR in children with asthma is 54.93% (95% CI: 53.05%–56.80%).ConclusionsThe comorbidity of AR and asthma is high in Chinese children. Statistically, the prevalence of AR was higher in children with asthma, as opposed to the prevalence of asthma in children with AR. The comorbidity rate of AR and asthma signifies the importance of improving the recognition and treatment under both conditions by respiratory physicians and otolaryngologists.
