Improving Nutrient Intake and Growth in Children With Multiple Food Allergies

* Hypothesis 1: Food allergies are associated with poor growth which can be corrected with nutrition intervention. * More than 10% of children with multiple food allergies will have a weight-for-age z-score less than - 2 at diagnosis. The z-score is a measure of the distance from the mean value, or 50th percentile on the growth chart. A z-score of less than - 2 indicates that the child is underweight. * Growth parameters of children with multiple food allergies will improve after intervention by a team that includes a dietitian and an allergist. * Hypothesis 2: Food allergies are associated with low micronutrient intake which can be corrected with nutrition intervention. o More than 30% of children with multiple food allergies will consume less than 67% of the Dietary Reference Intake for at least one macronutrient or micronutrient at diagnosis. * Macronutrient and micronutrient intake will increase after intervention by a team that includes a dietitian and an allergist. o • Hypothesis 3: Food allergies are related to behavioral feeding problems which can be corrected with nutrition intervention. * At least 25% of children with multiple food allergies will have behavioral feeding problems at diagnosis. * Prevalence of behavioral feeding problems will decrease after nutrition intervention.
