Are children on jejunal feeds at risk of iron deficiency?

Table 1 Patient characteristics: age, weight Z-scores, and primary diagnoses

Patient	Age at jejunal feeds commencement (yr)	Weight Z-scores	Primary diagnoses
1	6.9	1.48	Severe gastroesophageal reflux disease with oral aversion
2	0.5	-1.47	Global developmental delay with severe gastroesophageal reflux disease
3	14.1	-0.10	Gastroparesis and chronic nausea
4	2.3	-1.80	Craniosynostosis, and developmental delay
5	3.3	-1.10	Mitochondrial disease with, global developmental delay and severe gastroesophageal reflux disease
6	16.3	-4.00	Severe gastroesophageal reflux disease and gastroparesis
