Asthma and obesity in children: what do we know?

Abstract

The results of a large number of studies indicate the relationship of obesity and bronchial asthma in children. The review highlights the mechanisms of development of the so-called obese asthma: morphological changes in the respiratory tract, systemic inflammation, adipokine production, impaired glucose and insulin metabolism, genetic and epigenetic factors, changes in the microbiome of the respiratory tract and(or) intestines. The relationship of asthma and obesity can have both a genetic basis and can occur under the influence of a complex of pathogenic factors, and they can be especially important at the “early programming” stage. Obesity increases the risk of asthma development, and in patients with existing asthma due to a number of mechanisms it increases the severity or makes it difficult to achieve control of asthma. Studies showed that patients with obese asthma are distinguished by a more severe course of the disease, poor quality of life and a decreased response to therapy for asthma. Weight loss in children with asthma can lead to an improved well-being of patients, but data on the effectiveness of therapeutic interventions in these children is limited. Comorbidity of asthma and obesity is a complex multifactorial phenotype in children, which requires further study. Being overweight or obese needs to be taken into account as part of asthma treatment in this category of patients.
