We examined whether children's changes in salivary habituation to food vary based on weight status and/or allocating attention to a task. Children (31 non-overweight and 26 obese, ages 9-12 year) were presented with nine trials of a food stimulus and either listened to an audiobook (attention-demanding) or white noise (no-attention control). The salivary pattern differed significantly by weight status but not by condition or a condition by weight status interaction. This is the first study of salivary habituation in obese children; findings dovetail with an emerging set of evidence that obese individuals display distinctive biological responses to food.
我们研究了儿童唾液对食物的习惯化变化是否因体重状况以及/或注意力分配到任务上而有所不同。研究对象为 31 名非超重儿童和 26 名肥胖儿童(年龄 9-12 岁),他们观看了九次食物刺激物的试验,期间他们或听有声读物(注意力要求高)或白噪音(无注意力控制)。唾液模式因体重状况而异,但不受条件或条件与体重状况相互作用的影响。这是肥胖儿童唾液习惯化的第一项研究;研究结果与一组新的证据相吻合,即肥胖个体对食物表现出独特的生物学反应。
