The problem of overweight and obesity is a growing phenomenon in the entire population. Obesity is associated with many different metabolic disorders and is directly associated with an increased risk of death. The aim of the study was to assess the changes in body composition and physical fitness in children participating in an integrated weight-loss programme and to analyse the possible relationship between changes in body composition and improvements in fitness. Participants of the study were recruited from the “6–10–14 for Health”-multidisciplinary intervention programme for children aged 6 to 15 years old. A total of 170 patients qualified for the study, and 152 patients were enrolled. Statistically significant changes in body composition were found after the end of the intervention program, as measured by both BIA (bioimpedance) and DXA (Dual Energy X-ray Absorptiometry). The differences in KPRT (Kasch Pulse Recovery Test) results at baseline and after intervention are positively correlated with the difference in fat mass between baseline and the after-intervention measure. Improving physical fitness is positively correlated with a decrease in FM (fat mass) and an increase in FFM (fat-free mass) measured in both absolute values and %. Both BIA and DXA methods proved to be equally useful for measuring body composition.

Introduction: Abnormal body weight, including overweight and obesity, is a common health problem affecting children and adolescents. The present study aimed to analyse weight changes in children from preschool age to adolescence and to identify early predictors of excessive weight in adolescence, such as blood pressure and physical fitness observed in preschool children. Methodology: Data from 3075 children (1524 girls and 1594 boys), collected as part of the Gdańsk Centre for Health Promotion’s “Your Child’s Healthy Life” programme, were analysed, with each child assessed at ages 6, 10, and 14. Results: The results indicated that boys were more likely to be overweight, with a tendency for obesity to increase with age. Children who were overweight or obese at age 6 had a higher risk of remaining so for a longer period of time. In addition, low physical fitness (as measured by the KPRT test) and elevated blood pressure were significantly associated with excess body weight. Conclusions: The study underscores the importance of early intervention and consistent monitoring of childhood overweight and obesity to reduce their long-term impact on health.

Background/Objectives: Health-related quality of life has come to the forefront of the process of treatment. As a non-quantitative value, it requires the use of specialized tools to be measured. Despite the availability of general HRQoL assessment tools in Polish, a specific instrument for children with gastrointestinal (GI) disorders has not been developed. This study aims to describe the linguistic validity and reliability of the Polish version of the PedsQL™ Gastrointestinal Symptoms Module, which measured health-related quality of life (HRQoL) in children with gastrointestinal (GI) disorders. Methods: The PedsQL™ module, originally in English, was translated according to a structured process. Professional medical translators conducted the translations, and cognitive debriefing was performed with 35 respondents. Field testing involved 371 completed questionnaires (203 adults and 168 children). Results: Internal consistency was assessed using Cronbach’s alpha, with values generally exceeding 0.8 indicating high reliability. Conclusions: The final Polish version of the PedsQL™ GI Symptoms Module exhibits strong linguistic and content validity, making it suitable for both clinical trials and routine practice. Its use enables a comprehensive, culturally sensitive assessment of HRQoL in pediatric patients with GI disorders, thereby supporting individualized patient care and enhancing the physician–patient communication that is essential for effective treatment.

Background: Constipation in children often presents with non-specific symptoms, which can complicate its recognition in the pediatric emergency department (PED). Aim: This study aimed to characterize the clinical presentations, diagnostic context and testing patterns of children discharged with constipation from a tertiary pediatric emergency center. Methods: A retrospective analysis of medical records of patients under 18 years of age was conducted for patients who presented to the PED of a tertiary hospital in northern Poland from 2021–2024 and were ultimately discharged as K59.0 ICD-10 code (constipation). Demographic data, symptoms reported upon admission, and laboratory and imaging tests performed were collected and reviewed. Results: PED visits discharged with ICD-10 code K59.0 accounted for 2.97% of all 34,278 PED visits during study period. Among 1017 patients discharged with ICD-10 code K59.0, only 26.5% reported constipation as their main complaint. The most common complaints were abdominal pain (61.6%), vomiting (14.4%), and urinary symptoms (4.9%). Commonly suspected initial diagnoses were urinary tract infections or acute appendicitis. More complete documentation of constipation-related symptoms showed an exploratory association with less intensive diagnostic testing. Conclusions: Constipation should be routinely considered in children presenting to the PED with abdominal pain, vomiting, urinary symptoms, or rectal bleeding, even when bowel problems are not the main complaint. Structured history taking supported by simple diagnostic tools could help standardize assessment and support patient selection for further testing, although prospective studies are needed to determine clinical outcomes.
