Abstract

Childhood obesity has emerged as one of the most serious public health challenges of the 21st century, affecting children in countries at all income levels. The prevalence of childhood obesity has risen dramatically due to rapid urbanization, global food market expansion, sedentary lifestyles, and persistent socioeconomic inequalities. This narrative essay synthesizes current evidence on global epidemiology, determinants, health consequences, and interventions for childhood obesity, emphasizing the need for context-specific and equity-focused strategies. As of 2022, over 390 million children and adolescents aged 5–19 were overweight, including approximately 160 million classified as obese. Childhood obesity contributes to immediate and long-term metabolic, cardiovascular, respiratory, musculoskeletal, and psychosocial morbidity. Effective interventions require multilevel strategies, including family-based behavioral programs, school and community initiatives, fiscal policies, and regulatory measures. Sustained progress depends on integrating prevention into policy, strengthening surveillance, and ensuring equitable access to healthy environments and resources for all children.
