About this trial
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
Eligibility criteria
Qualifiers
Age 6 to 36 months at screening.
Clearly reduced intake versus usual (lower amount of food and/or fewer meals per day);
Prolonged meal duration (>30 minutes per meal);
Refusal or avoidance of familiar foods previously accepted;
Disqualifiers
Acute infections (e.g., tonsillitis, pneumonia, otitis media, viral febrile illness, acute diarrhea);
Chronic conditions affecting digestion or metabolism (e.g., celiac disease, malabsorption syndromes, chronic liver disease, chronic kidney disease, diabetes).
Neurodevelopmental or neurological conditions that impair feeding (e.g., cerebral palsy, autism spectrum disorder, global developmental delay).
Current or recent use of medications known to alter appetite or digestion/absorption (e.g., systemic corticosteroids, antiepileptics, prolonged antibiotics).
