The incidence and risk factors of immediate type food allergy during the first year of life in Korean infants: a birth cohort study

A total of 1177 infants and their parents completed this study. The prevalence of FA was 5.3% in infants. The three leading food allergens were hen's eggs (33/62), cow's milk (20/62) and peanut/nuts (8/62). Children with a history of maternal AD showed a significantly higher prevalence of FA (P = 0.012) [aRR = 3.17]. In addition, children who were born during autumn had a higher prevalence than those born during spring (p = 0.005) [aRR = 3.48]. In conclusion, we identified several characteristics that may influence the development of FA in the next generation, including maternal AD and autumn birth.
