Clinical characteristics and outcomes of children, adolescents and young adults with overweight or obesity and mental health disorders.

BACKGROUND: Mental disorders are important comorbidities in youth with obesity. Aim was to describe the clinical characteristics and outcome of youth with overweight or obesity having comorbid mental disorders. METHODS: Data from children, adolescents, and young adults (age 6-30 years) with overweight or obesity and mental disorders (depression, anxiety disorder, eating disorder, attention deficit disorder (ADHD)) from 226 centers in Germany and Austria participating in the Adiposity Patient Registry (APV) were analyzed and compared with those without reported mental disorders using regression modeling. RESULTS: Mental health comorbidity was reported in a total of 3969 out of 114,248 individuals with overweight or obesity: 42.5% had ADHD, 31.3% anxiety disorders, 24.3% depression, and 12.9% eating disorders. Being male (OR 1.39 (95%CI 1.27;1.52)), of older age (1.42 (1.25;1.62)), or with extreme obesity (1.45 (1.30;1.63)) were most strongly associated with mental health comorbidity. Regression analysis showed that mean BMI-SDS was significantly higher in the group of individuals with depression and eating disorders (BMI-SDS 2.13 (lower; upper mean:2.09;2.16) and 2.22 (2.17;2.26)) compared to those without reported mental health comorbidity (BMI-SDS 2.008 (2.005;2.011); p < 0.001). In youth with ADHD, BMI-SDS was lower compared to those without reported mental disorders (BMI-SDS 1.91 (1.89;1.93) vs 2.008 (2.005;2.011); p < 0.001). Proportion of severe obesity was higher in individuals with depression (23.7%), anxiety disorders (17.8%), and eating disorders (33.3%), but lower in ADHD (10.3%), compared to those without reported mental disorders (13.5%, p < 0.002). Proportions of dyslipidaemia and abnormal carbohydrate metabolism were not different in youth with and without reported mental health comorbidity. BMI-SDS change after one year of lifestyle intervention program ranged between -0.22 and -0.16 and was similar in youth without and with different mental disorders. CONCLUSION: Health care professionals caring for youth with overweight or obesity should be aware of comorbid mental disorders and regular mental health screening should be considered.

Poorly controlled pediatric type 1 diabetes mellitus is a risk factor for metabolic dysfunction associated steatotic liver disease (MASLD): An observational study.

OBJECTIVES: Recent studies have suggested a link between type 1 diabetes mellitus (T1D) and metabolic dysfunction associated steatotic liver disease (MASLD) in children and adolescent, but longitudinal evidence is lacking. This study aimed to investigate the potential association between poorly controlled T1D and elevated alanine aminotransferase (ALT), serving as a proxy for MASLD in children and adolescents over time. METHODS: The study included 32,325 children aged 2-17 years with T1D from Germany, Austria, and Switzerland who had undergone at least one assessment of liver enzyme levels recorded in the Diabetes-Patienten- Verlaufsdokumentation registry. Multivariable logistic and Cox regression models were calculated to show possible associations between T1D and elevated ALT values (>26 U/L in males, >22 U/L in females) as a proxy for MASLD. RESULTS: Children with poorly controlled T1D (HbA1c > 11%) exhibited increased odds of elevated ALT values, after adjustment for age, sex, diabetes duration and overweight (odds ratio [OR] 2.54; 95% confidence interval [CI], 2.10-3.10; p < 0.01). This finding is substantiated by a longitudinal analysis, which reveals that inadequately controlled T1D was associated with a higher hazard ratio (HR) of elevated ALT values compared to children with controlled T1D over an observation period extending up to 5.5 (HR: 1.54; 95% CI, 1.19-2.01; p < 0.01). CONCLUSION: In conclusion, the current study strongly links poorly controlled T1D in children and adolescents to MASLD irrespective of overweight. This association is not only present cross-sectionally but also increases over time. The study underscores the critical role of effective diabetes management in reducing the risk of MASLD in this population.

Pharmacological interventions for the management of children and adolescents living with obesity-An update of a Cochrane systematic review with meta-analyses.

IMPORTANCE: The effectiveness of anti-obesity medications for children and adolescents is unclear. OBJECTIVE: To update the evidence on the benefits and harms of anti-obesity medication. DATA SOURCES: Cochrane CENTRAL, MEDLINE, ClinicalTrials.gov and WHO ICTRP (1/1/16-17/3/23). STUDY SELECTION: Randomized controlled trials ≥6 months in people <19 years living with obesity. DATA EXTRACTION AND SYNTHESIS: Screening, data extraction and quality assessment conducted in duplicate, independently. MAIN OUTCOMES AND MEASURES: Body mass index (BMI): 95th percentile BMI, adverse events and quality of life. RESULTS: Thirty-five trials (N = 4331), follow-up: 6-24 months; age: 8.8-16.3 years; BMI: 26.2-41.7 kg/m2. Moderate certainty evidence demonstrated a -1.71 (95% confidence interval [CI]: -2.27 to -1.14)-unit BMI reduction, ranging from -0.8 to -5.9 units between individual drugs with semaglutide producing the largest reduction of -5.88 kg/m2 (95% CI: -6.99 to -4.77, N = 201). Drug type explained ~44% of heterogeneity. Low certainty evidence demonstrated reduction in 95th percentile BMI: -11.88 percentage points (95% CI: -18.43 to -5.30, N = 668). Serious adverse events and study discontinuation due to adverse events did not differ between medications and comparators, but medication dose adjustments were higher compared to comparator (10.6% vs 1.7%; RR = 3.74 [95% CI: 1.51 to 9.26], I2 = 15%), regardless of approval status. There was a trend towards improved quality of life. Evidence gaps exist for children, psychosocial outcomes, comorbidities and weight loss maintenance. CONCLUSIONS AND RELEVANCE: Anti-obesity medications in addition to behaviour change improve BMI but may require dose adjustment, with 1 in 100 adolescents experiencing a serious adverse event.

Rise in fasting and dynamic glucagon levels in children and adolescents with obesity is moderate in subjects with impaired fasting glucose but accentuated in subjects with impaired glucose tolerance or type 2 diabetes.

Background: Fasting levels of glucagon are known to be elevated in youth and adults with type 2 diabetes mellitus (T2D). Children and adolescents with obesity were previously reported to show increasing fasting and post-glucose-challenge hyperglucagonemia across the spectrum of glucose tolerance, while no data are available in those with impaired fasting glucose (IFG). Materials and methods: Individuals from the Beta-JUDO study population (Uppsala and Salzburg 2010-2016) (n=101, age 13.3 ± 2.8, m/f =50/51) were included (90 with overweight or obesity, 11 with normal weight). Standardized OGTT were performed and plasma glucose, glucagon and insulin concentrations assessed at baseline, 5, 10, 15, 30, 60, 90 and 120 minutes. Patients were grouped according to their glycemic state in six groups with normal glucose metabolism (NGM) and normal weight (NG-NW), NGM with obesity or overweight (NG-O), impaired glucose tolerance (IGT), impaired fasting glucose (IFG), IGT+IFG and T2D, and in two groups with NGM and impaired glucose metabolism (IGM), for statistical analysis. Results and conclusion: Glucagon concentrations were elevated in young normoglycemic individuals with overweight or obesity (NG-O) compared to normoglycemic individuals with normal weight. Glucagon levels, fasting and dynamic, increased with progressing glycemic deterioration, except in IFG, where levels were comparable to those in NG-O. All glycemic groups showed an overall suppression of glucagon during OGTT. An initial increase of glucagon could be observed in T2D. In T2D, glucagon showed a strong direct linear correlation with plasma glucose levels during OGTT. Glucagon in adolescents, as in adults, may play a role in the disease progression of T2D.
