A multicomponent intervention program modifies the cluster of insulin biomarkers, body composition, physical fitness, and behaviors in adolescents with overweight and obesity: a network perspective

Abstract

BackgroundOverweight and obesity in adolescence is a clear example of a complex system challenging, as it is a human development stage that obesity is associated with metabolic, neurodevelopmental, psychological, social, and behavioral changes, which makes treatment for this comorbidity di cult. Objective: analyze the relationships between sociodemographic, behavioral, breastfeeding, body composition, physical tness, and biomarkers of insulin metabolism before and after a multicomponent intervention with overweight and obese adolescents through network analysis.Methods: quasi-experimental, 37 overweight/obese adolescents, Intervention Group-IG = 17; Control Group-CG = 20. The program lasted six months, three weekly sessions of physical exercises, nutritional and psychological guidance. The assessment was performed in the moments before and after the intervention on body composition, physical tness and insulin biomarkers and lifestyle indicators. Network Analysis was used with three centrality indicators: proximity; strength and expected in uence.Results: Two networks were generated, for the moment before and after the intervention. For centrality measures before the intervention, closeness:
