A Study on the Identification of "Critical Turning Points" in the Progression of Adolescent Obesity to Metabolic Syndrome and Strategies for Early Intervention

To identify the "critical turning points" in the progression of adolescent obesity to metabolic syndrome (MetS), clarify its core characteristics and influencing factors, and propose scientifically sound and feasible early intervention strategies, thereby providing theoretical and practical support for halting disease progression and protecting the physical and mental health of adolescents,this study integrates relevant domestic and international research findings to elucidate the underlying mechanisms linking the two conditions. It analyzes key physiological, metabolic, and behavioral milestones during the progression process, summarizes influencing factors, and integrates intervention experiences to construct a comprehensive intervention system.The study found that the "critical turning points" in this progression are divided into two stages: the critical state of body fat accumulation in early adolescence (ages 10–13) and the onset of metabolic disorder in mid-adolescence (ages 14–16). Excessive body fat percentage (≥25% for males, ≥30% for females), the emergence of insulin resistance, and a waist-to-height ratio (WHR)height ratio ≥0.5 are its core characteristics, while genetic susceptibility, poor diet, lack of exercise, insufficient sleep, and psychological factors are the primary influencing factors. The study indicates that early identification of critical changes in body fat and metabolic indicators, coupled with the implementation of a multidimensional comprehensive intervention involving "diet + exercise + psychology + family," can effectively halt the progression of adolescent obesity to metabolic syndrome and reduce the risk of chronic diseases in adulthood.
