Insights
Obese children in specialized centers showed improved glucose metabolism, with many cases of impaired glucose tolerance reverting to normal. This positive trend occurred despite modest weight loss, highlighting the effectiveness of treatment interventions.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Obesity Research
Background:
- Obesity in children is linked to rising impaired glucose metabolism.
- Limited data exists on the progression of glucose metabolism issues in pediatric obesity.
- Large-scale, multi-center data on this topic is needed.
Purpose of the Study:
- To determine the prevalence of impaired glucose metabolism in obese children.
- To analyze the longitudinal course of glucose metabolism in this group.
- To assess outcomes using oral glucose tolerance tests (oGTT) within a pediatric obesity registry.
Main Methods:
- Observational, multi-center study using the Adiposity Patients Verlaufsbeobachtung (APV) registry.
- Cross-sectional analysis of 11,156 obese children and longitudinal analysis of 1,008.
- Classification of glucose metabolism based on American Diabetes Association criteria: impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and Type 2 diabetes (T2D).
Main Results:
- 12.6% of obese children exhibited abnormal glucose metabolism (5.99% IFG, 5.51% IGT, 1.07% T2D).
- In longitudinal follow-up, abnormal glucose metabolism decreased from 18.7% to 14.2%.
- 70.6% of children with initial IGT normalized their glucose tolerance; improvement was linked to BMI changes but not solely dependent on them.
Conclusions:
- Specialized treatment centers facilitate significant improvements in oGTT parameters for obese children.
- Positive metabolic changes were observed even with modest reductions in Body Mass Index (BMI) standard deviation score.
- These findings underscore the benefit of structured interventions for pediatric obesity and associated metabolic dysregulation.
Objective:
Although there is evidence of increasing prevalence of impaired glucose metabolism in obese children from smaller single cohorts, data are lacking on the progression of glucose metabolism in this patient group.We aimed to assess the prevalence and the longitudinal course of impaired glucose metabolism assessed by oral glucose tolerance test (oGTT) in a large multi-center pediatric obesity registry.
Subjects:
We performed an observational multicenter (n=84) cross-sectional (n=11 156) and longitudinal analysis (n=1008) on the course of glucose metabolism evaluated by oGTT in obese children documented in the Adiposity Patients Verlaufsbeobachtung (APV) registry. Patients were stratified with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and Type 2 diabetes (T2D), according to American Diabetes Association criteria.
Results:
A total of 12.6% of the children presented with abnormal glucose metabolism (5.99% IFG, 5.51% IGT, 1.07% T2D). Body mass index (BMI) correlated modestly with 2-h blood glucose (r=0.04, P<0.001).In the 1008 patients with follow-up oGTT, metabolic parameters improved and the percentage of abnormal glucose metabolism decreased from 18.7 to 14.2%. Of the children with initial IGT, 70.6% converted to normal glucose tolerance. The improvement in oGTT results was associated with, but not dependent on, a reduction of BMI s.d. score.
Conclusion:
In summary, we provide evidence for significant improvement of oGTT parameters in obese children treated in specialized treatment centers, even though reduction in BMI was modest.
