Hedonic hunger (i.e., extreme responsiveness to food) has been associated with obesity and poor diet, but findings in the existing literature have primarily been cross-sectional. The current study examined hedonic hunger as a prospective predictor of the longitudinal trajectory of unhealthy food and drink intake across adolescence. Ninth grade students from Los Angeles area high schools (analyzed sample = 3268) completed paper-and-pencil surveys across four annual waves; hedonic hunger was assessed at Wave 1, and unhealthy food and drink intake was assessed at Waves 1-4. Multilevel models showed a significant main effect of hedonic hunger and interactions between hedonic hunger and the linear and quadratic components of time. The association between hedonic hunger and unhealthy food and drink intake was strongest at Wave 1 and weakened over time, yet those with higher hedonic hunger reported greater unhealthy food and drink intake across the four years. Efforts to prevent and intervene upon hedonic hunger and its association with unhealthy food and drink intake during childhood and adolescence are warranted.
享乐性饥饿（即对食物的极端反应）与肥胖和不良饮食有关，但现有文献中的研究结果主要是横断面的。本研究考察了享乐性饥饿作为青少年时期不健康食物和饮料摄入纵向轨迹的前瞻性预测因子。洛杉矶地区高中的 9 年级学生（分析样本 = 3268）在四个年度波次中完成了纸笔调查；在第 1 波次评估了享乐性饥饿，在第 1-4 波次评估了不健康的食物和饮料摄入。多层次模型显示，享乐性饥饿和时间的线性和二次成分之间的相互作用具有显著的主要影响。在第 1 波次，享乐性饥饿与不健康的食物和饮料摄入之间的关联最强，随着时间的推移而减弱，但那些享乐性饥饿程度较高的人在四年内报告了更多的不健康食物和饮料摄入。有必要在儿童和青少年时期预防和干预享乐性饥饿及其与不健康食物和饮料摄入的关联。
