Childhood obesity is one of the most important pediatric public health problems because it is strongly associated with metabolic, cardiovascular, hepatic, respiratory, orthopedic and psychosocial complications. School age represents a critical period for identifying children at increased risk because many obesity related abnormalities, including insulin resistance, dyslipidemia, hypertension, metabolic dysfunction associated steatotic liver disease and impaired glucose metabolism, may already be present before adolescence. This review summarizes current evidence on clinical and metabolic predictors of obesity related complications in school age children. Particular attention is given to body mass index z score, waist circumference, waist to height ratio, duration and severity of obesity, pubertal status, blood pressure, acanthosis nigricans, family history, birth history, physical inactivity, sleep disturbance and dietary patterns. The review also discusses laboratory markers including fasting glucose, fasting insulin, HOMA IR, glycated hemoglobin, triglycerides, HDL cholesterol, alanine aminotransferase, uric acid, inflammatory markers and emerging adipokines. Evidence indicates that central adiposity, insulin resistance, atherogenic dyslipidemia, elevated blood pressure and hepatic enzyme abnormalities are among the strongest predictors of early cardiometabolic risk. However, no single marker is sufficient for comprehensive risk stratification. A combined clinical and biochemical approach is necessary, especially in children with severe obesity, early onset obesity, family history of type 2 diabetes or cardiovascular disease, and signs of metabolic syndrome. Early identification of high risk children can support targeted lifestyle intervention, rational screening and prevention of long term complications.
