Incidence and Early‐Life Risk Factors for Food Allergy in a Spanish Birth Cohort

Key Points

• To investigate the incidence of food allergy in children and identify early-life risk factors associated with it.
• Examined a Spanish birth cohort of children for food allergy incidence by age 4.
• Evaluated risk factors including atopic dermatitis and early-life exposures.
• Categorized food allergies into IgE-mediated and non-IgE-mediated forms.
• Food allergy affected 7.2% of children by age 4.
• Atopic dermatitis was identified as the main risk factor for IgE-mediated food allergy.
• Potentially modifiable early-life exposures were linked to non-IgE-mediated food allergy forms.
