Question: How do body mass index (BMI) and metabolic markers change over time in severely obese Korean children and adolescents receiving only lifestyle modifications?
Finding: Among 124 participants, BMI z scores decreased modestly over 2.6 years, primarily in younger prepubertal boys. However, most remained severely obese, with minimal improvement in body composition or metabolic markers.
Meaning: Lifestyle interventions alone have limited efficacy for severe pediatric obesity. Early and more intensive treatments are required. |
