Food craving refers to an intense desire to consume a specific food and is regularly experienced by the majority of individuals. Yet, there are interindividual differences in the frequency and intensity of food craving experiences, which is often referred to as trait food craving. The characteristics and consequences of trait and state food craving have mainly been investigated in questionnaire-based and laboratory studies, which may not reflect individuals' behavior in daily life. In the present study, sixty-one participants completed the Food Cravings Questionnaire-Trait-reduced (FCQ-T-r) as measure of trait food craving, followed by seven days of Ecological Momentary Assessment (EMA), during which they reported snack-related thoughts, craving intensity, and snack consumption at five times per day. Results showed that 86 percent of reported snacks were high-caloric, with chocolate-containing foods being the most often reported snacks. Individuals with high FCQ-T-r scores (high trait food cravers, HCs) thought more often about high-calorie than low-calorie snacks whereas no differences were found in individuals with low FCQ-T-r scores (low trait food cravers, LCs). Further, the relationship between craving intensity and snack-related thoughts was stronger in HCs than in LCs. Higher craving intensity was associated with more consumption of snacks and again this relationship was stronger in HCs than in LCs. Finally, more snack-related thoughts were related to more frequent consumption of snacks, independent of trait food craving. Thus, HCs are more prone to think about high-calorie snacks in their daily lives and to consume more snack foods when they experience intense cravings, which might be indicative of a heightened responding towards high-calorie foods. Thus, trait-level differences as well as snack-related thoughts should be targeted in dietary interventions.
食物渴望是指对特定食物的强烈渴望,大多数人都会经常体验到。然而,个体在食物渴望体验的频率和强度上存在差异,这通常被称为特质性食物渴望。特质性和状态性食物渴望的特征及后果主要在基于问卷的研究和实验室研究中进行了调查,而这些研究可能无法反映个体在日常生活中的行为。在本研究中,61名参与者完成了简版特质性食物渴望问卷(FCQ-T-r)以测量特质性食物渴望,随后进行了为期七天的生态瞬时评估(EMA),在此期间他们每天五次报告与零食相关的想法、渴望强度和零食摄入量。结果显示,报告的零食中有86%是高热量的,含巧克力的食物是最常被报告的零食。FCQ-T-r得分高的个体(高特质性食物渴望者,HCs)比低热量零食更频繁地想到高热量零食,而FCQ-T-r得分低的个体(低特质性食物渴望者,LCs)则没有发现差异。此外,HCs中渴望强度与与零食相关的想法之间的关系比LCs中更强。更高的渴望强度与更多的零食摄入量相关,而且这种关系在HCs中比在LCs中更强。最后,更多与零食相关的想法与更频繁的零食消费相关,与特质性食物渴望无关。因此,HCs在日常生活中更容易想到高热量零食,并且在经历强烈渴望时会摄入更多的零食,这可能表明对高热量食物的反应增强。因此,在饮食干预中应针对特质水平差异以及与零食相关的想法。
