Objectives: The association between obesity and gastroesophageal reflux disease (GERD) is well-established in adults; however, data in pediatric population is scarce. Our study aimed to assess the association between GERD and health-related quality of life (HRQoL) in overweight children., Methods: From April to August of 2020, we included children aged 7-18 years who attended the Endocrinological Outpatient Clinic at the Paediatric Institute, University of Debrecen, Hungary. The participants completed two questionnaires: the Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire (PGSQ) and the HRQoL questionnaire (PedsQL). Based on the criteria of the World Health Organization (WHO), the patients were categorized into two groups: an overweight or obese group and a group with normal weight., Results: A total of 107 children (51 % female, mean age 13.2 years, 46 % overweight or obese) completed the questionnaires. The median PGSQ score was similar in both groups (4.0 (IQR: 1.0-7.8) vs. 3.0 (IQR: 1.0-7.0), p=0.6). However, the total PedsQL score was significantly lower in the children with overweight or obesity compared to those with normal weight (80.1 (71.1-91.0) vs. 88.0 (76.1-94.6), p=0.031). The PedsQL score was lower among overweight patients with GERD symptoms than that of normal-weight patients without GERD symptoms., Conclusions: Our findings highlight the importance of raising awareness about GERD to enhance the HRQoL and prevent long-term complications in obese children., (© 2023 the author(s), published by De Gruyter, Berlin/Boston.)

Background Diabetes has previously been linked to mental health problems in children and adolescents, but more recent studies have yielded mixed findings. The aim of the current study was to compare symptoms of mental health problems in children and adolescents with and without type 1 diabetes (T1DM). Methods Life quality, subjective well-being, self-rated health, depression and somatic symptoms in children and adolescents with diabetes (n=130) were measured and compared to the results of a socio-demographically joined control group (n=177) which consists of healthy children and adolescents. Results A significant difference could be observed between the groups in well-being and depressive symptoms as according to the results, the research sample namely the children with T1DM could be described with significantly higher subjective well-being and mood, but with less physical symptoms and lower level of depression as those in the control group. Conclusions These findings suggest that T1DM is not associated with an increased risk of psychosocial problems, and confirm that even a severe disease of a child can lead to personal growth.

Aim: To study the prevalence of alterations of glucose and lipoprotein metabolism and the impact of acanthosis nigricans (AN) in childhood obesity., Patients and Methods: 113 obese children, 57 with simple obesity (SO) and 58 with obesity and AN (OAN). Oral glucose tolerance test was performed, serum glucose, insulin and lipoprotein parameters were determined, and insulin resistance/sensitivity indices were calculated., Results: Insulin resistance, basal and reactive hyperinsulinemia, impaired glucose tolerance (IGT) and dyslipidemia were found to be frequent conditions in children with OS as well as OAN. Reactive insulinemia was more pronounced in OAN than in SO, and insulin resistance was more frequent when AN was more prominent. Triglycerides were higher and HDL-C was lower, and atherogenic dyslipidemia was more frequent in OAN compared to SO., Conclusion: Children with obesity form a risk population. AN is a factor which can be used in metabolic risk factor clustering estimation in childhood obesity.

Aim: To study the prevalence of alterations of glucoregulation in childhood obesity., Participants: 250 obese children. Oral glucose tolerance test was performed, serum glucose and insulin were determined, and HOMA-IR was calculated., Results: Impaired fasting glucose (IFG) was found in 1.2% according to World Health Organisation criteria and 4.4% according to the criteria of the International Diabetes Federation. Impaired glucose tolerance (IGT) was found in 13.6%, type 2 diabetes mellitus (DM2) in 2.4%. Frequency of fasting glucose (FG) above 7.0 mmol/l was 1.2%. Basal hyperinsulinemia was increased in 70%, reactive hyperinsulinemia in 88%, frequency of elevated HOMA-IR was 78%. 120' insulin was increased in all cases with abnormal FG, IGT and DM2, HOMA-IR was elevated in 79% of patients with IGT and all patients with abnormal FG and DM2. Significant positive correlations were demonstrated between body mass index and insulin levels., Conclusion: Our data show that hyperinsulinemia can successfully compensate for insulin resistance in the majority of the obese children. Since IFG is less frequent than IGT there is a need for performing OGTT to demonstrate abnormality of glucoregulation in obese children.
