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., (© 2024.

Background and Objectives: GM2 gangliosidoses, a group of autosomal-recessive neurodegenerative lysosomal storage disorders, result from β-hexosaminidase (HEX) deficiency with GM2 ganglioside as its main substrate. Historically, GM2 gangliosidoses have been classified into infantile, juvenile, and late-onset forms. With disease-modifying treatment trials now on the horizon, a more fine-grained understanding of the disease course is needed., Methods: We aimed to map and stratify the clinical course of GM2 gangliosidoses in a multicenter cohort of pediatric and adult patients. Patients were stratified according to age at onset and age at diagnosis. The 2 resulting GM2 disease clusters were characterized in-depth for respective disease features (detailed standardized clinical, laboratory, and MRI assessments) and disease evolution., Results: In 21 patients with GM2 gangliosidosis (17 Tay-Sachs, 2 GM2 activator deficiency, 2 Sandhoff disease), 2 disease clusters were discriminated: an early-onset and early diagnosis cluster (type I; n = 8, including activator deficiency and Sandhoff disease) and a cluster with very variable onset and long interval until diagnosis (type II; n = 13 patients). In type I, rapid onset of developmental stagnation and regression, spasticity, and seizures dominated the clinical picture. Cherry red spot, startle reactions, and elevated AST were only seen in this cluster. In type II, problems with balance or gait, muscle weakness, dysarthria, and psychiatric symptoms were specific and frequent symptoms. Ocular signs were common, including supranuclear vertical gaze palsy in 30%. MRI involvement of basal ganglia and peritrigonal hyperintensity was seen only in type I, whereas predominant infratentorial atrophy (or normal MRI) was characteristic in type II. These types were, at least in part, associated with certain genetic variants., Discussion: Age at onset alone seems not sufficient to adequately predict different disease courses in GM2 gangliosidosis, as required for upcoming trial planning. We propose an alternative classification based on age at disease onset and dynamics, predicted by clinical features and biomarkers, into type I-an early-onset, rapid progression cluster-and type II-a variable onset, slow progression cluster. Specific diagnostic workup, including GM2 gangliosidosis, should be performed in patients with combined ataxia plus lower motor neuron weakness to identify type II patients.

Importance: Obesity reportedly increases the risk of pediatric multiple sclerosis (MS), but little is known about its association with disease course., Objective: To investigate the association of obesity with pediatric MS risk and with first-line therapy response among children with MS., Design, Setting, and Participants: This single-center retrospective study used the medical records and database at the Center for MS in Childhood and Adolescence, Göttingen, Germany. The study included 453 patients with relapsing-remitting pediatric MS and body mass index (BMI) measurement taken within 6 months of diagnosis. Onset of the disease occurred between April 28, 1990, and June 26, 2016, and the mean disease duration was 38.4 months. Data were collected from July 14, 2016, to December 18, 2017., Main Outcomes and Measures: Data on BMIs were stratified by sex and age using German BMI references and compared with the BMI data of 14 747 controls from a nationwide child health survey for odds ratio (OR) estimates. Baseline magnetic resonance imaging findings, intervals between first and second MS attacks, annualized relapse rates before and during treatment with interferon beta-1a or -1b and glatiramer acetate, frequency of second-line treatment, and Expanded Disability Status Scale (EDSS) scores were compared between nonoverweight (BMI≤90th percentile), overweight (BMI>90th-97th percentile), and obese (BMI>97th percentile) patients., Results: In total, 453 patients with pediatric MS were included, of whom 306 (67.5%) were female, and the mean (SD) age at diagnosis was 13.7 (2.7) years. At diagnosis, 126 patients (27.8%) were overweight or obese, with obesity associated with statistically significant twofold odds of MS in both sexes (girls OR, 2.19; 95% CI, 1.5-3.1; P < .001 vs boys OR, 2.14; 95% CI, 1.3-3.5; P = .003). Obese patients, compared with nonoverweight patients, had statistically significantly more relapses on first-line treatment with interferon beta and glatiramer acetate (ARR, 1.29 vs 0.72; P < .001) and a higher rate of second-line treatment (21 [56.8%] of 37 vs 48 [38.7%] of 124; P = .06). Baseline neuroimaging, interval between first and second MS attacks, pretreatment relapses, and EDSS progression scores were not correlated with BMI., Conclusions and Relevance: In this study, increased pediatric MS risk appeared to be associated with obesity, and obese patients did not respond well to first-line medications; altered pharmacokinetics appeared to be most likely factors in treatment response, suggesting that achieving healthy weight or adjusting the dose according to BMI could improve therapy response.

Clinical Significance: A large consumption of fermentable carbohydrates, for instance the high intake of sweetened beverages, is an important risk factor for overweight and obesity. As lemonades and fruit juices present high sugar content and quite low pH-values, overweight and obese children might also have an increased risk for dental caries and erosive tooth wear., Objectives: The aim was to analyze the prevalence and severity of erosive tooth wear and caries experience in children and adolescents with overweight, obesity and extreme obesity compared to children with normal weight and to determine a possible association between erosive tooth wear and caries experience., Methods: 223 children (4-17 years, n = 1476 primary and n = 4110 permanent teeth) were examined using standardized dental indices (BEWE, ICDAS, DMFT). Demographic and socio-economic data, eating habits, oral hygiene, fluoride supply and details of medical history were obtained from a questionnaire. Weight classification was based on age- and gender-specific relative body mass indices (BMI). Statistical analyses were done by Chi 2 -tests, Kruskal-Wallis tests, logistic and linear regressions. To determine a possible association between erosive tooth wear and caries experience Chi 2 -tests (prevalence to prevalence) and Spearman correlations (severity to severity) were performed (p < 0.05)., Results: Erosive tooth wear and caries experience in primary and permanent teeth were significantly increased in children with obesity and extreme obesity compared to normal weight children (p < 0.05). Higher BMI, age, gender, and the consumption of erosive snacks/beverages were identified as statistically significant risk factors for erosive tooth wear. Higher BMI, age, socio-economic factors, poor toothbrushing habits, and consumption of cariogenic beverages were identified as significant caries risk factors. Erosive tooth wear and caries showed a weak correlation in children with (extreme) obesity (Φ = 0.110 to 0.248)., Conclusions: Higher BMI of children and adolescents is significantly associated with a higher risk for erosive tooth wear and caries., (Copyright © 2019 Elsevier Ltd.

Purpose: To investigate associations between maternal and paternal sport participation, and children's leisure-time physical activity, and to explore differences by child gender., Method: The sample comprised 737 year five students (mean age: 11.0 ± 0.6 years, 52% male) recruited through the Fit for Pisa Project which was conducted in 2008 at 6 secondary schools in Goettingen, Germany. Maternal and paternal sport participation were assessed through child reports of mothers' and fathers' weekly participation in sport. Children's leisure-time physical activity was measured as minutes/week that children engaged in organized and nonorganized sport. Multiple linear regression was used to assess associations between maternal and paternal sport participation, and children's leisure-time physical activity., Results: Both maternal and paternal sport participation were positively associated with children's leisure-time physical activity (maternal: b = 34.20, p < .001; paternal: b = 25.32, p < .05). When stratifying analyses by child gender, maternal sport participation remained significantly associated with leisure-time physical activity in girls (b = 60.64, p < .001). In contrast, paternal sport participation remained significantly associated with leisure-time physical activity in boys (b = 43.88, p < .01)., Conclusion: Both maternal and paternal modeling positively influence children's leisure-time physical activity.

The "fit for pisa" intervention implemented daily physical education at five primary schools in Göttingen. The results of the evaluation show an increase in physical activity among the students participating in the programme. At the same time sedentary behaviour, like watching television, decreased remarkably. In the long run the promotion of an active lifestyle had improved the body mass index. The study emphasises the need for government funding to implement the programme across the country., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: The objective was to determine to what extent daily physical education can be implemented in primary schools, what barriers exist and how to overcome the mentioned barriers. Moreover, it was analysed to what extent daily physical education is accepted by teachers, external trainers, parents and students., Methods: Semi-structured interviews with parents (n=7), teachers (n=5) and external trainers (n=6) of the intervention schools. The intervention students (n=44) were surveyed within focus groups., Results: All surveyed groups appraised the implementation of daily school sports as successful. The cooperation between the schools and the sports club should be maintained during a comprehensive implementation of daily physical education. Besides an improved lessons quality teachers and external trainers reported an improved social behaviour of the children. Parents perceived positive effects on the child development. All groups believe that daily physical education increases the enjoyment of children in sports. As a certain barrier a lack of resources (e. g., facilities, equipment, financial resources) in the schools were mentioned., Conclusions: The cooperation between the schools and the sports club proved to be an applicable model to implement daily physical education. The combination of teachers and external trainers can contribute to a higher lesson quality. Considering the perceived potentials of daily physical education by all surveyed groups, a comprehensive implementation of systematic daily physical activity promotion in the primary school setting should be tapped more strongly in future., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: Pediatric lifestyle interventions have positive short-term effects on obese patients. Studies on long-term effects are still scarce in Europe. We investigated long-term weight patterns and sociodemographic predictors of a weight change in a large Central European (Germany, Austria and Switzerland) overweight pediatric cohort., Methods: The APV (Adiposity Patients Verlaufsbeobachtung) database was retrospectively analyzed; 157 specialized childhood obesity centers contributed standardized data of 29,181 patients [body mass index (BMI) ≥ 90th percentile; 5-25 years old] presenting between 2000 and 2012. BMI standard deviation scores (BMI-SDS) were analyzed in a 2-year follow-up and grouped according to BMI-SDS changes. Multiple logistic regression analyses were conducted to assess associations between sociodemographic factors and weight patterns., Results: 2-year follow-up data were available in 3,135 patients (54.6% female). Five distinct weight trajectories 'rapid weight loss' (n = 735, 23.4%), 'delayed success' (n = 697, 22.2%), 'cycling weight' (n = 43, 1.4%), 'initial weight loss' and 'weight rebound' (n = 383, 12.2%) and 'no weight loss throughout' (n = 1,277, 40.7%) best characterized long-term BMI-SDS changes. Younger and male patients were more likely to reduce weight and maintain weight loss., Conclusions: Our results suggest that an intervention before the onset of puberty seems promising for long-term weight maintenance in overweight children. Thus, new concepts are needed to improve long-term treatment success in patients with lower success rates., (© 2014 S. Karger AG, Basel.)

The increasing prevalence of risk factors associated with physical inactivity lead to an economic burden on society. The article uses the example of the prevention measure "fit for pisa" to investigate to what extent a full economic evaluation can provide a basis for decision-makers. The intervention integrated the daily physical education at 5 primary schools in Göttingen for the entire school term. The study is intended to provide information on short- and long-term potential savings. A process analysis identified the prevention performance from a societal perspective. Resource consumption was recorded in (partly) standardisedform and evaluated and also revealed the need for investment in sports halls with capacity to expand the programme to all primary schools in Göttingen. In the routine the implementation costs of half-day schools are 619 € per student year; for all-day schools 236 € per student year. The consideration of the short-term outcomes shows that TV viewing has decreased and physical activity has been strongly encouraged. The active life style promotion has shown an improvement on BMI in the medium-term. On the basis of a decision analytical model, a cost-benefit analysis of the program over the life course will be undertaken., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment., Methods: 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8%) attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators., Results: Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19) compared to those presenting moderate (Δ BMI-SDS -0.14) and high social risk (Δ BMI-SDS -0.11)., Conclusion: Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents., (Copyright © 2013 S. Karger GmbH, Freiburg)

Background: Obesity in children and adolescents is moving into the focus of public interest. Genetic as well as environmental factors are important in the etiology of obesity. The aim of this multicentre study was to correlate the weight of overweight or obese children and adolescents with that of their parents and siblings., Patients and Methods: Anthropometric and other data - comorbidities, various influencing factors and treatment - were collected from the adiposity data acquisition system for prospective surveillance (APS). Currently 125 medical centers and pediatric care clinics in Germany, Austria and Switzerland use the APS documentation. Until February 2008 data on a total of 37,062 children and adolescents had been collected., Results: Data to calculate the Body Mass Index (BMI) were obtained from both parents of 11,074 (29,9%) children and adolescents. The mean BMI Standard Deviation Score (SDS) of these children and adolescents was 2.46. Their mean age was 11.9 years; 46% were males. The mean BMI-SDS of these children and adolescents correlated significantly with the BMI-SDS of both the mother (r=0.29 [Spearman's rank correlation coefficient]) and the father (r=018, both p<0.0001). The correlation with the father's BMI was closer in adolescents (15-20 years, r=0.20) than in young children (<10 years: r=0.12). The correlation with the mother's BMI was independent of age. A multivariate model including the BMI of the parents as well as age and sex of the children and adolescents explained 10.0% of the variance. Significant influencing factors were BMI of the mother, sex and the relationship between BMI of mother, age and sex. Data for the BMI of siblings were available of 3,933 (10.6 %) children and adolescents. The correlation of the BMI of the children and adolescents with that of their siblings was +0.17 (p<0.0001). This correlation was highest in adolescence (<10 years.: r=0.17, 15-20 years.: r=0.24, both p<0.0001)., Conclusion: The patient's weight correlated more strongly with the mother's than the father's weight or that of the siblings.

In the last two decades in Germany and other countries physical activity of children and adolescents declined while sedentary lifestyle increased. Physical inactivity in childhood and youth is related with coronary heart disease risk factors and higher prevalence of obesity. International recommendations suggest daily 60 minutes or more moderate to vigorous physical activity and less than 2 hours sedentary activity in leisure.

The article reports on measurements of D dimer, a terminal plasmic lysis product of crosslinked fibrin, with an enzyme immunoassay (ELISA) employing recently developed specific monoclonal antibodies. Due to its sensitivity the test can be used on plasma samples. The D dimer concentrations in patients with deep vein thrombosis diagnosed by laboratory apparatus were significantly increased compared to a control group; in one patient with additional pulmonary embolism, the level was even higher. Moderately elevated concentrations of D dimer were observed in the hypercoagulable state of pregnancy, puerperium and during the postoperative course. This reduces the specificity of the test with regard to the recognition of thromboembolic episodes under these conditions. Obstetric patients with disseminated intravascular coagulation (DIC) showed excessively increased levels of D dimer. Hence, a marker function with regard to the recognition of thromboembolic disease can be attributed to the D dimer; the diagnosis of DIC can be confirmed if very high concentrations are detected.
