Asthma is a common inflammatory disease in childhood. The interaction of genes, environment and host factors contributes to the development and progression of asthma, and the heterogeneity of asthma leads to the complexity of asthma phenotype classification. In this article, we reviewed recent analyses of asthma phenotypes in children using different criteria, including the age of onset, breathing pattern, clinical characteristics, airway inflammatory cells, risk factors, immunity and genetics, and assessed the prognosis of previous asthma phenotypes based on the above criteria, hoping to provide evidence for the treatment and prognosis of children with asthma.
