Childhood obesity and cardiac risk in youth: Emerging challenges toward 2050.

Pediatric obesity is increasing at an alarming rate, affecting over 381 million children worldwide and emerging as a critical public health issue. According to World Health Organization (WHO) 2016, 40% of adults are overweight and 13% are obese, highlighting obesity's persistence throughout life. Childhood obesity significantly heightens the risk of adult obesity and cardiovascular diseases (CVD) such as atherosclerosis and coronary artery disease, potentially leading to a global health crisis by 2050. Genetic predispositions identified through genome-wide association studies (GWAS) contribute to elevated body mass index (BMI), yet lifestyle factors reduced physical activity, prolonged screen time, and consumption of high-calorie, low-nutrient foods remain key drivers. This study aim is to explore the Real-world data (RWD) on childhood obesity from major countries, prevalence, risk factors, and cardiovascular consequences of pediatric obesity, evaluating public health initiatives, lifestyle interventions, and therapeutic strategies to address this growing concern. Data collected from PubMed, Scopus, and Springer databases reveal that childhood obesity is closely linked to hypertension, dysglycemia, dyslipidemia, and other cardiovascular disorders (heart attack, arrhythmias and stroke). The WHO Global Action Plan on Physical Activity 2018-2030 (GAPPA) emphasizes urgent preventive measures. Current management strategies include lifestyle modification, pharmacotherapy, and bariatric surgery. Glucagon-like peptide-1 (GLP-1) receptor agonists such as semaglutide and liraglutide are effective for weight management but commonly cause gastrointestinal adverse effects. The SURMOUNT-5 trial demonstrated superior weight-loss outcomes with tirzepatide, with a similar gastrointestinal safety profile. Emerging therapies including cagrilintide plus semaglutide, oral agents such as orforglipron and danuglipron, and the triagonist retatrutide may improve adherence and accessibility; however, these agents remain investigational and are currently under clinical evaluation. Despite promising advancements, gene therapy for pediatric obesity remains in the experimental phase. Overall, addressing childhood obesity requires multifaceted interventions combining public health initiatives, behavioral changes, and novel therapeutic strategies to mitigate cardiovascular risks and promote sustainable health outcomes.
