Despite high rates of obesity in adolescents, little is known about their individual motives for eating caloric foods for reasons unrelated to hunger. The goal of this study was to provide a preliminary validation of the "Kids Palatable Eating Motives Scale" (K-PEMS), a self-report survey designed to identify individual motives for eating tasty foods in adolescents. The study also sought to determine if any specific motive(s) can account for variance in BMI and binge-eating disorder (BED) traits which can exacerbate obesity.
BMIz and responses to the K-PEMS and the Children's Binge Eating Disorder Scale (C-BEDS) were obtained from inner-city low-income African American adolescents. Linear and logistic regressions were used to identify K-PEMS motives that were associated with greater BMIz and binge-eating traits.
The K-PEMS identified eating tasty foods for Social, Conformity, Reward Enhancement, and Coping motives. Higher frequency of eating tasty foods for Social and Conformity motives and lower frequency of eating these foods for Reward Enhancement accounted for 39% of the variance in BMIz among the overweight and obese adolescents. In contrast, eating for Coping motives was related to a 3-fold increase in the amended provisional criteria for BED in children which occurred in 7% of this young minority sample.
The K-PEMS can be used to identify adolescents' primary motives for eating tasty foods. These motives may provide early identification of obesity and binge-eating risk but more importantly, can be tailor-targeted to affect specific behavioral and/or cognitive changes to prevent these conditions in adulthood.
尽管青少年肥胖率很高，但对于他们出于与饥饿无关的原因食用高热量食物的个人动机却知之甚少。本研究的目的是对“儿童美味饮食动机量表”（K-PEMS）进行初步验证，该量表是一项自我报告调查，旨在确定青少年食用美味食物的个人动机。该研究还试图确定是否有任何特定动机可以解释体重指数（BMI）和暴饮暴食症（BED）特征的差异，而这些特征会加剧肥胖。
从市中心低收入非裔美国青少年中获取BMIz以及他们对K-PEMS和儿童暴饮暴食症量表（C-BEDS）的回答。使用线性回归和逻辑回归来确定与较高BMIz和暴饮暴食特征相关的K-PEMS动机。
K-PEMS确定了出于社交、从众、奖励增强和应对动机而食用美味食物的情况。超重和肥胖青少年中，出于社交和从众动机食用美味食物的频率较高，而出于奖励增强动机食用这些食物的频率较低，这解释了BMIz差异的39%。相比之下，出于应对动机进食与儿童BED修订后临时标准的三倍增加有关，在这个年轻的少数族裔样本中有7%出现这种情况。
K-PEMS可用于识别青少年食用美味食物的主要动机。这些动机可能有助于早期识别肥胖和暴饮暴食风险，但更重要的是，可以针对性地影响特定的行为和/或认知变化，以预防成年期出现这些情况。
