Women with body weight dissatisfaction (BWD) have long-term negative assessments of their body weight, which are often associated with poor eating behavior. In this study, we investigated the effect of body-related information on the food cue processing and attention of women with BWD. Sixty-eight women were recruited and assigned to either a BWD (NPSS-F > 2) (n = 32) or a no body weight dissatisfaction (NBWD) group (NPSS-F < 1) (n = 36). We measured attentional bias to food cues (high- and low-calorie) with a food probe task after exposure to body-related information and recorded eye tracking data. Body-related images were presented prior to a pair of stimulus images (food-neutral or neutral-neutral). Body-related information and food type were repeated measure factors in our study. Our results showed that the first fixation duration bias for high-calorie foods was significantly longer than for low-calorie foods after exposure to overweight cues in the BWD group. Compared with the NBWD group, the BWD group showed longer first fixation duration bias for high-calorie foods after exposure to overweight cues. The direction for high-calorie foods was significantly more often than that for low-calorie foods in the BWD group after exposure to body-related information. Our findings suggest that compared to women with NBWD, women with BWD may be more susceptible to body-related information, resulting in increased attention to high-calorie foods.
体重不满的女性(BWD)对自己的体重长期持负面评价,这往往与不良的饮食行为有关。在这项研究中,我们调查了与身体相关的信息对 BWD 女性的食物线索处理和注意力的影响。我们招募了 68 名女性,并将她们分为 BWD(NPSS-F>2)(n=32)或无体重不满(NBWD)组(NPSS-F<1)(n=36)。在暴露于与身体相关的信息后,我们使用食物探针任务测量了对食物线索(高卡路里和低卡路里)的注意力偏差,并记录了眼动跟踪数据。在我们的研究中,与身体相关的信息和食物类型是重复测量因素。我们的结果表明,在 BWD 组暴露于超重线索后,对高卡路里食物的首次注视持续时间偏差明显长于对低卡路里食物的首次注视持续时间偏差。与 NBWD 组相比,BWD 组在暴露于超重线索后对高卡路里食物的首次注视持续时间偏差更长。在暴露于与身体相关的信息后,BWD 组中高卡路里食物的注视方向明显多于低卡路里食物。我们的研究结果表明,与无体重不满的女性相比,BWD 女性可能更容易受到与身体相关的信息的影响,从而增加对高卡路里食物的注意力。
