Key result
Childhood obesity prevalence increases steadily, reaching ~14% in late adolescence with high long-term persistence.

Persistent adolescent obesity may warrant monitoring; leaves open whether interventions alter long-term trajectories.
Cohort (n=1,023)
Childhood obesity at age 7 strongly predicts obesity at age 17, highlighting the need for early intervention and prevention strategies before and during puberty.
Cho et al. (2003) conducted a cohort in Childhood obesity (n=1,023). Childhood obesity vs. Normal weight children was evaluated on Prevalence and persistence of obesity. The prevalence of obesity increased significantly with age, reaching 14.1% at age 16, with 71.4% of obese boys and 60.0% of obese girls at age 13 remaining obese at age 16.
