At baseline and 1-year, mindfulness, depression, insulin resistance (IR), and body composition were assessed with validated instruments.ResultsOne-year retention was 71% (n = 12) in MBI; 81% (n = 13) in CBT. At 1-year, depression decreased (Cohen’s d = 0.68) and IR decreased (d = 0.73) in adolescents randomized to MBI compared to those in CBT. There were no significant between-condition differences in mindfulness, adiposity, or BMI.DiscussionOne-year outcomes from this randomized, controlled pilot trial suggest that brief MBI may reduce depression and IR in at-risk adolescents. Replication and exploration of mechanisms within the context of a larger clinical trial are necessary.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier NCT02218138.
