Nearly 40% of US children and adolescents have a body mass index that markedly increases their risk for serious metabolic and cardiopulmonary sequelae. Current childhood obesity rates, for the first time in US history, predict a decline in life US expectancy. Importantly, childhood obesity is a key driver of health disparities in the US, with obesity disproportionately affecting African-American, Hispanic-Latino, and Native American children. A key contributor to the sequelae of obesity is sedentariness. Thus, best practice in obesity management includes both reducing sedentariness and establishing durable increases in daily physical activity, however, attrition from planned exercise programs remains high. A key challenge to initiating and sustaining physical activity in children with obesity is the extreme dyspnea (breathlessness) they experience. This is due to the altered thoracic mechanics of obesity which lead to enhanced inspiratory muscle fatigue and dyspnea, with even modest physical activity. Our group has confirmed that among adolescents, higher body mass index (BMI) associates with lower inspiratory muscle endurance (r= -0.680, p=0.049, n=14), and that this lower endurance correlates with more frequent dyspnea (r= - 0.672, p=0.023, n=12). Treating obesity-related inspiratory muscle impairment and dyspnea is a promising approach to support physical activity in children with obesity but is yet unproven.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '17 Years', 'minimumAge': '8 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Documented informed consent from legal guardian and assent from participant as appropriate.\n* Children 8 to 17 years of age with obesity (BMI ≥ 95th percentile for age and sex) being seen at Duke Healthy Lifestyles clinic.\n* Participants (or parent/guardian) must have access to the internet and an approved smart device/computer.\n* Child must have a designated caregiver who expresses a commitment to encourage the participant to complete the study procedures.\n* Participant and legal guardian must speak and read English.\n\nExclusion Criteria:\n\n* Prior enrollment in an IMR program.\n* Contraindications for IMR including a history of recent lung surgery, recent pulmonary embolism, or history of recurrent spontaneous pneumothorax\n* Progressive neurological or neuromuscular disorders or need for chronic O2 therapy.\n* Inability to complete baseline measurements in a satisfactory manner according to the judgment of the research coordinator or PI.\n* Current self-reported pregnancy or planning to become pregnant.\n* Body weight greater than 300 pounds.\n* Any condition in the opinion of the PI that would not allow safe conduct of study procedures (including IMR, MIP testing or step-test), such as a physical disability, recent musculoskeletal injury or illness, current and ongoing evaluation for undiagnosed cardiopulmonary or neurologic symptoms, undiagnosed chest pain, pneumothorax in the past 12 months, inner ear surgery in the past 12 months, or undiagnosed syncopal episodes.'}, 'identificationModule': {'nctId': 'NCT05412134', 'acronym': 'BREATHE Fit', 'briefTitle': 'Inspiratory Muscle Rehabilitation in Children With Obesity', 'organization': {'class': 'OTHER', 'fullName': 'Duke University'}, 'officialTitle': 'Inspiratory Muscle Rehabilitation in Children With Obesity to Promote Physical Activity', 'orgStudyIdInfo': {'id': 'Pro00110494'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Active inspiratory muscle rehabilitation (IMR) group', 'description': 'Each participant will be provided a PrO2™ device and trained on its use and its accompanying PrO2 Fit™ app. The PrO2™ is a flow-resistive device that provides inspiratory resistance via a fixed 2mm orifice and has Bluetooth connectivity to most IOS/Android devices or Mac/Windows computers.
