Asthma and Obesity in Children

Area of Science:

• Pediatric Pulmonology
• Pediatric Endocrinology
• Clinical Immunology

Background:

• Obesity is a growing concern in children and adolescents, linked to increased asthma risk.
• Existing research on the impact of childhood obesity on lung function shows inconsistent results.
• Understanding the complex interplay between obesity and asthma in pediatric populations is crucial.

Purpose of the Study:

• To review pathological mechanisms connecting childhood obesity and asthma development.
• To evaluate factors influencing the obesity-asthma relationship in children.
• To propose distinct clinical subtypes of obese-asthmatic children.

Main Methods:

• Literature review of epidemiological and physiological-molecular data.
• Analysis of common disease-modifying factors (age, sex, ethnicity, atopy, metabolic alterations).
• Identification and characterization of potential clinical subtypes.

Main Results:

• Three main clinical subtypes of obese-asthmatic children are proposed: those with atopy, insulin resistance, or dyslipidemia.
• These subtypes are differentiated by epidemiological data and underlying physiological-molecular pathways.
• Disease-modifying factors significantly influence asthma onset and phenotype in obese children.

Conclusions:

• The proposed subtypes may represent a unique obese-asthmatic phenotype, impacting clinical management and research.
• A multidisciplinary approach, integrating endocrinological and pneumological evaluations, is recommended for obese-asthmatic children.
• Personalized and tailored treatments may be possible with further validation through longitudinal studies.
