Food Allergy in Children in China

Area of Science:

• Allergy and Immunology
• Public Health
• Epidemiology

Background:

• Food allergy prevalence is increasing in China.
• Limited studies describe national patterns of food allergies.
• Geographic and environmental factors influence food allergy distribution.

Purpose of the Study:

• To review regional variations in food allergy prevalence across China.
• To identify common food allergens by age group and geographic region.
• To highlight challenges in food allergy management in China.

Main Methods:

• Literature review of studies on food allergies in China.
• Analysis of regional prevalence data.
• Identification of common allergens and management challenges.

Main Results:

• Higher prevalence in eastern and southern coastal regions compared to inland areas.
• Common childhood allergies include egg and milk; shellfish, wheat, and fruit allergies show regional differences.
• Emerging peanut and tree nut allergies noted in megacities, but prevalence is low compared to Western countries.
• Significant management gaps exist, including lack of standardized diagnostics, limited access to oral food challenges, and a shortage of trained allergists.
• Limited availability and affordability of epinephrine autoinjectors pose a critical challenge for anaphylaxis management.

Conclusions:

• Food allergy landscape in China is complex, influenced by geography and environment.
• Addressing systemic deficiencies in diagnostics, workforce, and emergency care is crucial for improving outcomes.
• Concerted efforts from policymakers, healthcare systems, and pharmaceutical companies are needed to enhance food allergy management.
