Depressive symptoms in youth may be a risk factor for obesity, with altered eating behaviors as one possible mechanism. We tested whether depressive symptoms were associated with observed eating patterns expected to promote excessive weight gain in two separate samples. In Study 1, 228 non-treatment-seeking youth, ages 12-17y (15.3±1.4y; 54.7% female), self-reported depressive symptoms using the Beck Depression Inventory. Energy intake was measured as consumption from a 10,934-kcal buffet meal served at 11:00am after an overnight fast. In Study 2, 204 non-treatment-seeking youth, ages 8-17y (13.0±2.8y; 49.5% female), self-reported depressive symptoms using the Children's Depression Inventory. Energy intake was measured as consumption from a 9835-kcal buffet meal served at 2:30pm after a standard breakfast. In Study 1, controlling for body composition and other relevant covariates, depressive symptoms were positively related to total energy intake in girls and boys. In Study 2, adjusting for the same covariates, depressive symptoms among girls only were positively associated with total energy intake. Youth high in depressive symptoms and dietary restraint consumed the most energy from sweets. In both studies, the effects of depressive symptoms on intake were small. Nevertheless, depressive symptoms were associated with significantly greater consumption of total energy and energy from sweet snack foods, which, over time, could be anticipated to promote excess weight gain.
青少年时期的抑郁症状可能是肥胖的一个风险因素，而改变的饮食习惯可能是其中的一个潜在机制。我们在两个独立的样本中测试了抑郁症状是否与预期会促进体重过度增加的观察性进食模式有关。在研究 1 中，228 名非治疗寻求的青少年，年龄 12-17 岁（15.3±1.4 岁；54.7%为女性），使用贝克抑郁量表自我报告抑郁症状。能量摄入是通过在 11:00am 空腹后食用 10934 卡路里的自助餐来测量的。在研究 2 中，204 名非治疗寻求的青少年，年龄 8-17 岁（13.0±2.8 岁；49.5%为女性），使用儿童抑郁量表自我报告抑郁症状。能量摄入是通过在下午 2:30 标准早餐后食用 9835 卡路里的自助餐来测量的。在研究 1 中，控制身体成分和其他相关协变量后，抑郁症状与男孩和女孩的总能量摄入呈正相关。在研究 2 中，在调整相同协变量后，只有女孩的抑郁症状与总能量摄入呈正相关。抑郁症状较高的青少年和饮食限制者从甜食中摄入最多的能量。在这两项研究中，抑郁症状对摄入的影响都很小。然而，抑郁症状与总能量和甜食摄入显著增加有关，随着时间的推移，这可能会导致体重过度增加。
