Feeding and Eating Disorders of Childhood

This observational, prospective, single-center study aims to evaluate changes in the fecal microbiota of pediatric patients receiving exclusive enteral nutrition following the introduction of Compleat® Paediatric Nature Mix, an enteral formula made from food-derived ingredients. Secondary objectives include the assessment of digestive tolerance, bowel habits, sleep quality, enteral feeding rate, and related medication use over a six-month follow-up period.

Functional poor appetite is common in young children and may be linked to suboptimal micronutrient intake and feeding behavior. This study evaluates whether a zinc-containing oral supplement (Biolizin syrup) can improve eating behavior in children aged 6 to 36 months who have poor appetite without an identifiable medical cause. Participants are followed for 42 days with clinic visits at Day 0, Day 7, Day 21, and Day 42. Caregivers complete validated questionnaires about feeding difficulties and eating behavior; the child's weight and length/height are measured at each visit. Safety is assessed through review of adverse events and routine laboratory tests; serum zinc may be measured according to the protocol. The primary outcome is the change from baseline to Day 42 in the total score of a validated feeding-difficulty scale. Secondary outcomes include changes in Children's Eating Behaviour Questionnaire (CEBQ) subscales, WHO growth indices, serum zinc (if measured), and overall safety
