Abstract

BackgroundMindfulness-based intervention (MBI) may offer a novel means of preventing excess weight gain in adolescents, theoretically by decreasing stress-eating through altering executive functioning (EF) and food-reward sensitivity. MethodsN = 54 12–17y girls and boys at-risk for excess weight gain (i.e., BMI ≥70th percentile or two biological parents with reported obesity [BMI ≥30 kg/m2]) participated in a 1.5-year follow-up of a pilot randomized controlled trial comparing 6-week/6-session MBI (n = 29) and a health education (HE) control (n = 25). Laboratory stress-eating, food-reward sensitivity, EF, perceived stress, and BMI/adiposity were re-assessed at 1.5-years with validated measures. Changes from baseline to 1.5-year follow-up were explored with ANCOVA, accounting for the respective baseline outcome, age, and sex. ResultsCompared to MBI (M = −21, SE = 59), HE had greater increases in stress-eating from baseline to 1.5-years (M = 194, SE = 63, Cohen's d = 0.59, p = .01). There were no other between-condition differences. DiscussionMBI may prevent worsening stress-eating for adolescents at-risk for excess weight gain. The potential for MBI as an intervention for stress-eating and ultimately, weight stabilization warrants testing in an adequately-powered trial.
