The main findings from these studies are a modest long-term reduction of both total and abdominal adiposity accompanied by improved physical fitness, while unchanged adiposity in the untreated controls led to decreased physical fitness and deteriorating insulin sensitivity. In addition, we found significantly impaired health related quality of life in the obese children compared to their normal weight peers. We showed that our multidisciplinary lifestyle treatment improved health related quality of life of the obese children after 1 year. We observed a significantly increased postprandial ghrelin response after the multidisciplinary treatment, but no effect on inflammatory markers, nor on gut hormones PYY and GLP-1. Finally, we propose an alternative for the definition of the metabolic syndrome in children, since the usefulness of its current dichotomous form is questionable. We show that a multivariate prediction model based on the individual components of the metabolic syndrome expressed as standard deviation scores (SDS) has a good predictive value regarding increased HOMA-IR SDS.
