Abstract

BACKGROUND & AIMS:

To evaluate the knowledge and practice of pediatricians, pediatric gastroenterologists, allergists and nutritionists regarding the primary prevention of food allergy.

METHODS:

A descriptive, cross-sectional study that enrolled pediatricians (n = 80), pediatric gastroenterologists (n = 120), allergists (n = 100) and nutritionists (n = 220). A self-administered questionnaire concerning the current recommendations was used.

RESULTS:

Despite the lack of current recommendations, 17.1% (n = 89) of all professionals, mainly nutritionists, recommended a maternal exclusion diet during pregnancy. More professionals in the sample group, 40.8% (n = 212), recommended a maternal exclusion diet during breastfeeding, and the rates of recommendation were higher in nutritionists and pediatricians compared to allergists and pediatric gastroenterologists (p < 0.001). Regarding the recommended timing of the introduction of complementary feeding, 41.9% (n = 218) of the professionals recommended modifying the age of introduction to prevent the development of food allergy. The majority of the professionals believed that prebiotics (61.2%; n = 318) and probiotics (44.4%; 231) prevent the development of food allergy. The recommended age of introduction for the main allergenic foods was 12 months.

CONCLUSIONS:

This study revealed that there are gaps in the knowledge of professionals about the primary prevention of food allergy.
