COVID-19大流行和减少其传播的公共卫生措施增加了压力。压力与饮食行为的改变有关，这在一定程度上可能是由与食物有关的动机的影响所驱动的。为了研究与covid相关的压力对食物动机的影响，我们招募了成年人（N = 429; 272 F, 157 M），于2020年5月通过亚马逊MTurk完成了一项在线调查。评估了当前与covid相关的压力、回顾性的covid前压力以及与五类（甜食、水果、咸味零食、蔬菜和快餐）个性化首选食物相关的动机。食物动机测量包括等待的意愿、花费较少精力的意愿（敲击手指）、花费较多精力的意愿（开合跳）以及为假设的食物交付付费的意愿。每种食物类型的食物动机使用一种新的工具进行评估，该工具设计用于对多种食物类型的食物动机的多个方面进行简要评估。参与者愿意为快餐支付最多的钱，其次是甜食，并且相对于其他类型的食物，甜食愿意等待更长的时间。虽然快餐和糖果也产生了最多的花费精力和较少精力的意愿，但花费较少精力购买水果的意愿与快餐和糖果相似，而花费较多精力购买水果的意愿与快餐相当。参与者最不愿意为蔬菜付费或花费较少的精力。与新冠病毒相关的压力水平越高，人们就越愿意付出更多的努力，花更多的钱购买食物。在大流行期间收集的这些数据表明，在多种激励措施中，深加工食品和甜食具有很高的激励价值，与冠状病毒相关的压力增加了所有食品类别的食物动机。缓解压力和针对压力与暴饮暴食之间联系的干预措施可能有助于限制COVID-19大流行对肥胖的影响。
The COVID-19 pandemic and public health measures to reduce its transmission have increased stress. Stress is associated with alterations in eating behavior which may be partly driven by effects on food-related motivation. To investigate effects of COVID-related stress on food motivation, we recruited adults (N = 429; 272 F, 157 M) to complete an online survey via Amazon MTurk in May 2020. Current COVID-related stress, retrospective pre-COVID stress, and motivation in relation to individualized preferred foods from five categories (sweet snacks, fruit, savory snacks, vegetables, and fast food) were assessed. Food motivation measures included willingness to wait, willingness to expend low effort [finger taps], willingness to expend high effort [jumping jacks], and willingness to pay for hypothetical delivery of the food item. Food motivation for each food type was assessed using a novel instrument designed for brief assessment of multiple aspects of food motivation across multiple food types. Participants were willing to pay the most for fast food followed by sweet snacks, and willing to wait longer for sweet snacks relative to other food types. While fast food and sweets also generated the most willingness to expend high and low effort, willingness to expend low effort for fruit was similar to that for fast food and sweets, and willingness to expend high effort for fruit was comparable to that for fast food. Participants were least willing to pay or expend low effort for vegetables. Higher COVID-related stress levels were associated with willingness to expend more effort and pay more for food items. These data collected during the pandemic demonstrate that highly processed and sweet foods have high motivating value across multiple measures of motivation, and COVID-related stress increases food motivation across food categories. Interventions to mitigate stress and target the link between stress and overeating may help to limit the effects of the COVID-19 pandemic on obesity.
