Effects of Oral Nutrition Supplements in Children With Disease Associated Underweight

The purpose of this study is to test whether the provision of ONS to malnourished children across Europe, in addition to standard counselling, will improve weight gain and other outcomes. The hypothesis to be tested is: • Supplementation with ONS in malnourished paediatric patients will lead to increased WFH gain, as well as less malnutrition related complications (e.g. infections). Primary outcome • The change in BMI z-score over the intervention period of 3 months Secondary outcomes • The change in WFH-weight for height (z-scores) over the intervention period of 3 months
