Obesity-related asthma in children: A role for vitamin D

Area of Science:

• Pediatric Allergy and Immunology
• Nutritional Biochemistry
• Pediatric Endocrinology

Background:

• Excess adipose tissue is linked to increased inflammation and can worsen asthma severity in children.
• Low serum vitamin D levels are prevalent in children with both asthma and obesity.
• Vitamin D possesses anti-inflammatory properties, suggesting a potential role in managing inflammatory conditions.

Purpose of the Study:

• To review the complex interplay between asthma, obesity, and vitamin D deficiency (hypovitaminosis D) in pediatric populations.
• To explore the potential of vitamin D supplementation as an adjunctive therapy for childhood asthma, particularly in cases associated with obesity.
• To highlight the current gaps in research regarding vitamin D pharmacokinetics and therapeutic efficacy in children with obesity-related asthma.

Main Methods:

• Literature review synthesizing current research on asthma, obesity, hypovitaminosis D, and vitamin D supplementation in children.
• Analysis of existing studies examining the relationship between body mass index, asthma control, and vitamin D status.
• Identification of research needs concerning vitamin D pharmacokinetics and clinical outcomes in pediatric obesity and asthma.

Main Results:

• Children with asthma and obesity frequently exhibit low vitamin D levels.
• Vitamin D supplementation is a proposed safe and inexpensive adjunctive therapy for various conditions.
• There is a significant lack of research on the pharmacokinetics and therapeutic benefits of vitamin D in children with obesity-related asthma.

Conclusions:

• The intersection of childhood asthma, obesity, and hypovitaminosis D warrants further investigation.
• Vitamin D supplementation may offer a safe therapeutic avenue for pediatric obesity-related asthma.
• More research is crucial to understand vitamin D's role and optimize its use in this specific pediatric population.
