Mindfulness-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.
N = 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/m]) 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.
Compared 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.
MBI 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.
基于正念的干预（MBI）可能为预防青少年体重过度增加提供一种新方法，理论上通过改变执行功能（EF）和食物奖励敏感性来减少应激性进食。
N=54 名 12-17 岁超重风险的女孩和男孩（即 BMI≥第 70 百分位数或有两位报告肥胖的亲生父母[BMI≥30kg/m]）参加了一项为期 1.5 年的试点随机对照试验的随访，该试验比较了 6 周/6 节 MBI（n=29）和健康教育（HE）对照（n=25）。在 1.5 年时，使用经过验证的测量方法重新评估了实验室应激性进食、食物奖励敏感性、EF、感知压力和 BMI/肥胖。使用协方差分析（ANCOVA）从基线到 1.5 年随访期间探索变化，考虑到各自的基线结果、年龄和性别。
与 MBI（M=-21，SE=59）相比，HE 从基线到 1.5 年的应激性进食增加更大（M=194，SE=63，Cohen's d=0.59，p=0.01）。两组之间没有其他差异。
MBI 可能预防超重风险的青少年应激性进食恶化。MBI 作为应激性进食和最终体重稳定的干预措施具有潜力，值得在一项充分有效的试验中进行测试。
