Design outcomes

Primary

MeasureTime frame
Main Objective: An explorative pilot for determining the effectiveness of vitamine D on improving symptoms of fatigue in children between 12 and 18 years old. The amount of vitamin D will be determined by calcidiol levels at the start of inclusion. ;Secondary Objective: To determine the amount and characteristics of the children who manage to go from a calcidiol serum level of 75 nmol/L after 3 months of vitamin D suppletion.;Primary end point(s): Primary endpoint of this study will be the difference in symptoms of fatigue as measured by the CIS-k, PedsQL and PedsQL fatigue questionnaire before and after vitamine D suppletion for three months. This will be matched to the calcidiol serum level at the start of inclusion. ;Timepoint(s) of evaluation of this end point: At 3 months after vitamin D suppletion
