What are the beliefs of pediatricians and dietitians regarding complementary food introduction to prevent allergy?

Identify the recommendations that general pediatricians and registered dietitians provide to parents and delineate any differences in counselling.A 9-item survey was distributed to pediatricians and dietitians online and by mail. Information on practitioner type, gender, length of practice and specific recommendations regarding complementary food introduction and exposure was collected.181 surveys were returned with a 54% response rate from pediatricians. It was not possible to calculate a meaningful dietitian response rate due to overlapping email databases. 52.5% of all respondents were pediatricians and 45.9% were dietitians. The majority of pediatricians and dietitians advise mothers that peanut abstinence during pregnancy and lactation is unnecessary. Dietitians were more likely to counsel mothers to breastfeed their infants to prevent development of atopic dermatitis than pediatricians. Hydrolyzed formulas for infants at risk of developing allergy were the top choice of formula amongst both practitioners. For food allergy prevention, pediatricians were more likely to recommend delayed introduction of peanut and egg, while most dietitians recommended no delay in allergenic food introduction.In the prophylaxis of food allergy, pediatricians are less aware than dietitians of the current recommendation that there is no benefit in delaying allergenic food introduction beyond 4 to 6 months. More dietitians than pediatricians believe that breastfeeding decreases the risk of atopic dermatitis. Practitioners may benefit from increased awareness of current guidelines.Food allergy is a hypersensitivity reaction to food allergens initiated by the immune system [1,2]. IgE-mediated food allergy (type I), forms the bulk of food-induced allergic responses and results in elevated allergen-specific serum IgE antibodies. It is not clear how the gut mucosal immune system is oriented toward sensitization versus immune tolerance when exposed to dietary antigens [3]. Food allergy is
