The rising prevalence of childhood & adolescent obesity is a pressing global health concern linked to genetic, behavioral, and environmental influences. Poor dietary habits, excessive screen time, and limited physical activity contribute to excessive weight gain during formative years. Hormonal changes during puberty can further impact metabolism, increasing obesity risk. Early-life exposure to ultra-processed foods and sugary beverages exacerbates the issue, leading to insulin resistance and metabolic disorders. Psychological factors, including stress and social stigmatization, also play a critical role in obesity development. Long-term consequences include an increased likelihood of obesity persisting into adulthood, raising the risk of cardiovascular diseases and diabetes. Addressing these concerns requires a comprehensive approach involving family-based interventions, school programs promoting physical activity, and public health policies aimed at improving nutrition. Preventive measures at an early stage are crucial for mitigating future health complications.
