Calcium intake in children with persistent cow's milk allergy and those who had achieved full-dose intake after school age

Abstract

Introduction: The current status of calcium intake in children with cow's milk allergy that persists after school age and the calcium intake after desensitization of full dose of cow's milk need to be clarified based on the actual dietary content.

Method: Nutritional intake was evaluated based on the results of a dietary survey conducted using the dietary record and photographic methods in children with persistent cow's milk allergy after school age who visited the Aichi Children's Health and Medical Center from March 2018 to August 2019. Children in the Elimination group who completely eliminated or consumed < 5 mL of milk were compared with children in the Desensitization group who consumed ≥ 200 mL.

Results: Calcium intake in the Elimination and Desensitization groups were 47.3% and 61.3%, respectively (P=0.104). Most affected children in both groups (91% and 85%) did not reach the estimated average requirement.

Conclusion: Although cow's milk intake achieved full dose after school age, daily intake of dairy products was low and calcium intake remained inadequate. Regular nutritional intake surveys and nutritional dietary guidance are necessary even for those children who have achieved full-dose intake.
