P0674 - Early Introduction of Peanut, Egg, and Milk Among Black and White Food-Allergic Children in the FORWARD Study

Background:
Early dietary introduction of certain allergenic foods before 6 months of age may decrease food allergy (FA) incidence.

Objectives:
Considering racial differences in US FA prevalence, this study characterizes timing of peanut, egg, and milk introduction among food-allergic Black and White children.

Methods:
Black and White children (0-12 years old) with a diagnosed FA were enrolled into a prospective, multi-site, cohort study. In the intake survey, parents of children with peanut (n=182; 68 Black/114 White), egg (n=136; 99 White/37 Black), and milk (n=82; 27 Black/55 White) allergies reported timing of dietary introduction of each allergenic food. Age of introduction was categorized into ≤6 months, 7-10 months, and ≥11 months. Pearson X2 tests were used to compare timing of food introduction by race.

Results:
Only 2.9% of Black children with peanut allergy were introduced to peanut at ≤6 months, 8.8% between 7-10 months, and 88.2% at ≥11 months, compared to White children (21.9%, 25.4%, and 52.6% respectively) (X2=4.66; p<0.001). For milk, 25.9% of Black children were introduced at ≤6 months, 18.5% between 7-10 months, and 55.6% at ≥11 months, compared to White children (49.1%, 23.6%, and 27.3%) (X2=6.52;p=.04). Finally, 10.8% of Black children were introduced egg at ≤6 months, 27.0% between 7-10 months, and 62.2% at ≥11 months, compared to White children (25.3%, 32.3%, and 42.4%) (X2=5.07;p=.08).

Conclusions:
Peanut, milk, and egg are introduced earlier to White children compared to Black children, possibly contributing to racial differences in FA prevalence. Education on early introduction, especially the 2017 Prevention of Peanut Allergy Guidelines, may be needed.
