Attentional Bias to High-Calorie Food in Binge Eaters With High Shape/Weight Concern

Individuals with high shape/weight concern (SWC) place disproportionate emphasis on shape and weight in evaluating their self-worth, making them more vulnerable to body-related cues. Binge eaters (BE), who are obsessed with devouring high-calorie foods, would show severe symptomatology, especially when they have clinically high SWC. The present study attempted to elucidate how SWC influences binging based on attentional patterns toward high-calorie food cues. A total of 120 participants were selected and divided into four groups: (1) BE with high SWC, (2) BE with low SWC, (3) healthy controls (HC) with high SWC, and (4) HC with low SWC. BE and SWC status were respectively determined using the Eating Disorder Diagnostic Scale (DSM-5) and the Eating Disorder Examination Questionnaire. All participants completed the same free-viewing task, measuring initial fixation latency and total fixation duration. BE with high SWC showed attentional bias toward high-calorie food cues in terms of significantly faster initial fixation latency and longer total fixation duration, whereas BE with low SWC and the HC groups did not show any differences. The results revealed that SWC level makes unique contributions to BE's initial orienting bias toward and difficulty disengaging from high-calorie food cues. This may indicate that BE with high SWC merely worry about eating high-calorie food in a cognitive way, but not controlling actual binging behavior. The current study of attentional bias elucidated the role of SWC as a potential maintenance factor of being concerned and binging in BE.

Mindfulness in Eating Is Inversely Related to Binge Eating and Mood Disturbances in University Students in Health-Related Disciplines

The purpose of the study was to investigate the relationship between mindful eating, disordered eating and mood in university students in health-related disciplines. A total of 221 university students participated in the study; 102 students studied sport and exercise science (SS), 54 students pharmacy sciences (PS), and 65 students health sciences (HS). Participants completed the Binge Eating Scale (BES), the Mindful Eating Questionnaire (MEQ), and the Profile of Mood State questionnaire (POMS). 41% of the students were classified as binge eaters and 57% were above the POMS threshold of depression. Binge eaters were found to have significantly lower MEQ score and significantly higher total mood disturbance scores (TMD) compared to non-binge eaters (p < 0.01). Students with a high depression score exhibited no differences in the MEQ score but a significantly higher BES score compared to non-depressed students (p < 0.01). Gender differences were found in the MEQ with females exhibiting significantly higher scores in the MEQ score and in all MEQ subscales compared to males, with the exception of the emotional subscale that females were noted to have a lower score compared to males (p < 0.01). The MEQ score was inversely related to the BES score (r = −0.30, p < 0.01) and TMD (r = −0.21, p < 0.05). The MEQ score was a significant negative predictor of the variance of the binge eating behavior of the students (B = −3.17, p < 0.001). In conclusion, mindfulness in eating is inversely related to the binge eating behavior and mood state of university students studying health-related subjects and is a significant negative predictor of disordered eating behavior in this high risk population.

Binge eating symptoms prevalence and relationship with psychosocial factors among female undergraduate students at Palestine Polytechnic University: a cross-sectional study

Background Eating disorders pose a serious challenge to health services due to psychosocial and medical problems. Binge eating disorder (BED) is characterized as a pattern of overeating episodes followed by shame, distress and guilty feelings. Among eating disorders, BED has the highest prevalence, especially among females. The literature reported that BED is associated with nutritional status, socio-demographic factors, and psychological factors in different countries. This study aims to examine the prevalence of binge eating symptoms and its relationship with selected variables (i.e. socio-demographics, nutritional status and dietary habits). Methods One hundred fifty-four female undergraduate students, from three different faculties at Palestine Polytechnic University, participated in the study. All the students who consented to join the study were assessed in terms of weight status using body mass index, dietary habits and medical profile. The screening for presence of binge eating symptoms was done using BEDS-7. The psychosocial factors were assessed by validated Arabic version of DASS-21. Results Half of the participants (50%) had binge eating symptoms. No association between binge eating symptoms and socio-demographic variables was found. Similarly, binge eating symptoms was not related to body weight status, however, it was associated with eating between meals and number of snacks. A significantly higher score on depression, stress and anxiety was found among binge eaters than non-binge eaters. Conclusion It was concluded that binge eating symptoms have considerable prevalence among the study participants, and it was significantly correlated with psychosocial factors. Future studies are needed to examine other risk factors and correlations. Educational programs are also recommended to increase the awareness of eating disorders as well as to promote healthy eating patterns.

Sheep residual feed intake and feeding behaviour: are ‘nibblers’ or ‘binge eaters’ more efficient?

Efficient liveweight gain is an important component of profitable livestock systems. In cattle, studies of residual feed intake (RFI) suggest that there are behavioural differences between efficient and inefficient animals; more efficient animals have less frequent, larger feed events. There is limited understanding of the association between feeding behaviour and feed conversion efficiency (measured as RFI) in sheep. We hypothesised that more efficient sheep would have lower daily number of meals but larger meal size than would less efficient sheep and that feeding behaviour would be repeatable between measurements conducted using the same sheep at different ages. Feeding behaviour was monitored at post-weaning (average 311 days) and hogget (average 533 days) age in a single cohort of maternal composite 2014-born ewes undergoing feed-efficiency testing. Feed intake (kg/day) and daily feeding behaviour (meal number, meal size and eating rate) were recorded by using automated feeders. Feed intake was recorded daily for a minimum of 40 days (mean 41 days), following a 14-day adaptation period. Animals were fed a pelleted hay-based diet, with liveweight measured three times per week. At both ages of measurement, a positive (P < 0.01) linear relationship was established between average daily number of meals and RFI. In these cohorts, as daily number of meals increased, RFI became more positive (less efficient). Meal size (kg DM) was also related to RFI (P < 0.05) when measured at the hogget age, with meal size decreasing with an increasing RFI (less efficient animals had smaller meals). These analyses suggest that sheep feeding behaviour, and in particular daily meal number, is associated with feed efficiency.

The role of enteroceptive awareness in eating disorders: A study on a group of binge eaters

IntroductionEnteroceptive awareness is defined as the ability to perceive the body states. Such ability is provided by the enteroceptors, organs and structures specifically designated to receive both internal and external stimuli. This capability, especially the perception of satiation, seems to be lacking in individuals suffering from Eating Disorders and there is no procedure to increase this ability.ObjectivesThe primary purpose is to improve patient's enteroceptive awareness. We tested whether patients diagnosed with binge eating disorder (BED), while deprived of eyesight, would better focus on their internal signals, such as the satiation feeling, and therefore eat less and slower.MethodsFor the first time, 29 patients with BED were deprived of vision during a meal. In a standardized procedure, participants ate two different meals, the first one while deprived of eyesight, the second one, a week later, in normal conditions. Both the amount of eaten food and the total time to complete the meal were taken into account during each of the meals. The patients filled in a Visual Analogue Scale (VAS) questionnaire at the end of each meal, in order to evaluate the experience and their internal feelings.ResultsThe results show that patients suffering from BED, when deprived of eyesight, eat less food, take more time to finish the meal and experience the same level of satiation with respect to the normal condition.ConclusionThis procedure could be of great interest for the implementation of specific intervention protocols that are aimed at the recovery of enteroceptive awareness in patients with eating disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.
