Implication

Longitudinal observational study finds behavioral treatment substantially reduces severe obesity in young children but not adolescents, indicating an urgent need for earlier intervention.

Key Points

To determine whether the degree of baseline obesity predicts the efficacy of 3-year behavioral treatment and to investigate interactions with participant age.
Conducted a 3-year longitudinal observational study of 643 children and adolescents aged 6 to 16 years (49% female) treated at the National Childhood Obesity Center in Stockholm, Sweden, between 1998 and 2006.
Categorized participants into three age tiers (6–9, 10–13, and 14–16 years) and two severity tiers: moderately obese (BMI-SD score 1.6 to <3.5) and severely obese (BMI-SD score ≥3.5).
Evaluated changes in BMI-SD scores after 3 years of behavioral intervention, defining a reduction of ≥0.5 units as clinically significant.
Clinically significant BMI-SD score reductions occurred in 58% of severely obese young children (mean reduction: -0.7 [95% CI, -0.80 to -0.54]) and 44% of moderately obese young children (mean reduction: -0.4 [95% CI, -0.55 to -0.32]).
Treatment efficacy declined with older age groups; only 20% of 10–13-year-olds and 8% of 14–16-year-olds with moderate obesity achieved significant reductions, while severely obese adolescents showed no change in mean BMI-SD score, with only 2% attaining clinically significant reduction.
Age was a significant negative predictor of achieving BMI-SD reduction during the 3-year intervention (odds ratio: 0.68 units per year [95% CI, 0.60 to 0.77]).
