- Brief summaryThe objective of this study is to compare a newly developed ambulatory programme with a maximal clinical intervention programme. Patients were randomly assigned to either clinical treatment, involving hospitalization for 26 weeks, or an intensive ambulatory programme. Both treatment programmes consist of an intensive family-based intervention including exercise, nutrition and behaviour modification for the children and their caregiver(s). In a pilot study we found that our clinical treatment programme could achieve a sustainable decrease in BMI for 1 year after fisnishing a six month treatment programme. Therefore a randomized controlled trial was set up to evaluate whether the efficacy of an inpatient treatment programme for morbidly obese children (8-18y) is superior to the best possible care in an ambulatory setting. To compare changes in BMI and BMI=z-scores, body composition, body circumferences, insulin sensitivity, bloodpressure, liverfunctiontest, lipid profiles and exercisetest.
