  1. Values are mean ± SD. Baseline values refer to the 300 adolescents with metabolic syndrome (MetS) enrolled in the intervention; post-intervention values are stratified by adherence category.
  2. P values are from one-way ANOVA comparing the three adherence categories (low, moderate, high) at 12 months.
  3. BMI, body mass index; BP, blood pressure; HbA1c, glycated hemoglobin; HDL-C, high-density lipoprotein cholesterol; CAP, controlled attenuation parameter; PA, physical activity.
