Childhood obesity continues to rise worldwide. A large meta-analysis including approximately 45.8 million children and adolescents from 2033 studies across 195 countries reported a global obesity prevalence of 8.5%. Excess body weight substantially increases the risk of hypertension in young people, with prevalence rates of 16.35% in children with obesity and 6.79% in those overweight, compared with 2.57% in children of normal weight.

Initial measurement, monitoring, and treatment principles emphasize accurate blood pressure (BP) assessment. Ambulatory blood pressure monitoring (ABPM) is the preferred method, with reassessment every 1–2 years, supported by standardized office BP measurements at each clinical visit. When ABPM is unavailable, repeated standardized office BP readings or structured home BP monitoring over three days are recommended. Treatment goals focus on achieving BP below the 95th percentile for age, sex, and height, or lower where age-based thresholds apply. Lifestyle modification remains first-line therapy, including salt reduction, weight management, and regular physical activity, with pharmacological treatment reserved for those with persistent or advanced hypertension.

Management pathways highlight early assessment for hypertension-mediated organ damage (HMOD). In children with primary hypertension and obesity, treatment may be initiated irrespective of disease stage if HMOD is present. For those without HMOD, therapy escalation depends on symptom burden, hypertension severity, and response to lifestyle measures. In children with obesity and BP between the 90th and 95th percentiles, targeted screening for cardiovascular and metabolic risk markers guides further intervention.

Compounding risk factors for obesity-related hypertension accumulate across the life course, from prenatal influences and early growth patterns to adolescent lifestyle behaviors and environmental exposures. Critical windows for intervention exist at individual and population levels, spanning family-based support, school-based education, young adult weight management, and broader policy measures targeting diet, physical activity, and the food environment.

Conclusion: An integrated approach combining precision medicine with population-level health strategies, supported by digital health tools and longitudinal data from early life, is essential to inform effective and sustainable interventions.
