Abstract

Purpose: To assess knowledge of Canadian dietitians on the topics of food allergy and food allergy prevention guidelines, including introduction of allergenic solids to infants at risk of food allergy.
Methods: An online survey was distributed via email listservs targeting Canadian dietitians.
Results: In total, 144 of 261 dietitians completed the survey (60.5%). Respondents recommend introduction of peanut (89.5%) and allergenic solids (91.2%) within the recommended age of 4–6 months for infants at high risk of food allergy, but only 26.2% recommend offering peanut three times per week once it has been introduced. In identifying what constitutes an infant at high risk of developing peanut allergy, dietitians expressed lower comfort levels and lower number of correct responses.
Conclusions: Dietitians demonstrated they are up to date regarding the timing of introduction of allergenic solids, but not the frequency of consumption once introduced, for infants at high risk of food allergy. They also expressed low comfort level identifying risk factors for peanut allergy. There are opportunities for further education of dietitians, as well as potential to further utilize dietitian services for the benefit of patients with food allergy or who are at risk for food allergy.

Résumé

Objectif. Évaluer les connaissances des diététistes au Canada sur les allergies alimentaires et les directives de prévention des allergies alimentaires, y compris l’introduction de solides allergènes chez les nourrissons à risque de développer des allergies alimentaires.
Méthodes. Un sondage en ligne a été distribué par l’entremise de gestionnaires de liste de diffusion par courriel ciblant des diététistes au Canada.
Résultats. Au total, 144 diététistes sur 261 ont répondu au sondage (60,5 %). Les répondants recommandent l’introduction des arachides (89,5 %) et des solides allergènes (91,2 %) dans la plage d’âge recommandée de 4 à 6 mois chez les nourrissons présentant un risque élevé d’allergie alimentaire. Par contre, seulement 26,2 % recommandent d’offrir des arachides 3 fois par semaine une fois qu’elles ont été introduites. Lorsqu’il s’agit de définir un nourrisson à haut risque de développer une allergie aux arachides, les diététistes se sont montrés moins à l’aise et ont donné moins de bonnes réponses.
Conclusions. Les diététistes ont démontré avoir des connaissances à jour quant au moment d’introduire des solides allergènes, mais pas en ce qui a trait à la fréquence de consommation une fois introduits chez les nourrissons à haut risque d’allergie alimentaire. Ils se sont également montrés peu à l’aise d’identifier les facteurs de risque d’allergie aux arachides. Il existe des occasions d’approfondir la formation des diététistes, ainsi qu’un potentiel d’utiliser davantage les services de diététistes au profit des patients atteints ou à risque d’allergies alimentaires.
