Background: Few studies are reported on interventions that have been carried out in children and adolescents using diaphragmatic breathing (DB) together with methods like counseling, muscle relaxation, therapeutic exercise, and music therapy. Objective: The goal of the review is to evaluate the effectiveness of DB as complementary therapy in the stress of the pediatric population (6–18 years old). Methods: Detailed research was carried out in the current literature to find relevant studies published from 2010 to October 2024 in PubMed and Cochrane Library. Thirteen studies that fulfilled the inclusion criteria were included in the study. Nine studies involved obese and overweight pediatric populations and the other four involved pediatric patients. Results: The interventions comprised two 8-week studies in an obese pediatric population, seven studies in healthy children and adolescents with normal weight. The studies were based on DB, muscle relaxation, nutrition, counseling, music therapy, and slow breathing exercises. The participants in the intervention group improved in comparison to those in the control group in terms of stress and depression in most included studies, in terms of school performance in two studies, in terms of better family relationships in one study, and showed improvement in anthropometric indicators in two studies. In four studies that involved pediatric patients, stress and fear of medical procedures were reduced. Conclusions: DB can effectively contribute on its own or in combination with other therapeutic methods to improving physiological and psychological indicators in the pediatric population. It is useful to integrate stress management programs that include DB training as clinical practice in primary healthcare and in school schedules for elementary and high-school students.

Background/Objectives: Childhood obesity appears to be an alarmingly growing global threat. Current evidence has shown that obesity can be successfully managed with interventions targeting movement skills, motor coordination and physical activity. However, data concerning physiotherapy practice are limited. We aimed to assess the impact of therapeutic exercise on the 6-minute walk test (6-MWT) in obese children and adolescents. Methods: A total of 31 obese children and adolescents (BMI > 30 kg/m²), 18 males and 13 females, aged from 8 to 18 years, were enrolled. Two study groups were formed: the control group (Group A), comprising ten children; and the intervention group (Group B), comprising 21 children. Daily exercise habits were obtained via interview; anthropometric data (weight, height and BMI) were recorded; and 6-MWT parameters, blood pressure and oxygen saturation (SaO₂) were assessed before and after a 4-month intervention program consisting of breathing and aerobic exercises. Results: There was a statistically significant increase in 6-minute walk distance (+43.34, p < 0.001) and an improvement in body weight (p < 0.01), blood pressure (p < 0.01) and oxygen saturation (p < 0.03) in Group B after the 4-month training program. Conclusions: All results highlight the potential of physical exercise in clinical practice to improve functional status and achieve weight loss. Future randomized controlled trials, including individualized therapeutic exercise programs in larger samples of obese children, are much anticipated.

Background: Chronic stress in childhood and adolescence leads to excessive cortisol secretion, adipokines production and obesity with all the negative mental and physical effects on the health of individuals and adulthood. Objectives: The aim of the present non-randomized controlled trial was to investigate the effect of a stress management protocol with diaphragmatic breathing (DB) and physiotherapy exercise on stress, body composition, cardiorespiratory and metabolic markers of children and adolescents with morbid obesity. Methods: The study included 31 children and adolescents (5–18 years old) with morbid obesity (22 in the intervention arm and 9 controls). All participants completed anxiety questionnaires and a self-perception scale. Forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), blood pressure (BP) and SpO₂ were measured. Fasting glucose, uric acid, triglycerides, HbA1c, (AST/SGOT), (ALT/SGPT), HDL, LDL, insulin, ACTH, cortisol, HOMA-IR, 17-OH, S-DHEA, SHBG were assessed, and anthropometric measurements were also performed. Results: In the intervention group, 4 months after the treatment, an improvement was noted in the BMI, BMI z-score, waist-to-height ratio, FEV1, SpO₂, pulse and systolic BP. HDL increased, ALT/SGPT and insulin resistance improved. Positive changes were observed in temporary and permanent stress and self-esteem of children in the intervention group, including anxiety, self-perception, physical appearance, etc. Conclusions: A combined exercise and DB protocol has a positive effect on stress, by improving body composition, reducing insulin resistance, and ameliorating physical and mental health and quality of life of pediatric patients with morbid obesity.
