Implicit associations in eating disorders: An experimental study using implicit associations test

IntroductionGreenwald et al. (1998) developed The implicit Association Test (IAT) to measure automatic concept-attribute associations. The assumption of the test is that strongly associated (compatible) attribute-concept pairs should be easier to classify together than are weakly associated or opposed (incompatible) attribute concepts. Ease of classifying is measured by the response times and errors in performing such categorizations.ObjectivesThe aim of this study was the evaluation, at an implicit level, of the attitude concerning fat people in a sample of Eating Disorders (ED).MethodsA IAT modeled to assess self-esteem the attitude concerning fat and slim persons has been administered to 17 Anorexia Nervosa (AN), 14 Bulimia Nervosa (BN), 17 Binge Eating (BED) patients and 32 healthy controls (HC). In IAT, the target categories were represented by the words «FAT-SLIM» and «good / bad». Stimuli were images of faces of overweight and normal weight people and positive/negative word. A positive IAT effect underline an implicit tendency to associate the category «FAT» with positive attributes, instead a negative IAT effect suggest an implicit tendency to associate the same category with negative attributes.ResultsResults showed a significant difference between HC and clinical groups in implicit attitude concerning overweight persons. HC showed positive IAT effect, instead AN, BN and BED showed a negative IAT effect. No correlations between implicit attitude and clinical variables were found.ConclusionThese results suggest a common implicit tendency in ED’s groups, compared with controls, to negatively judge overweight persons.

IntroductionGreenwald and co-workers developed The implicit Association Test (IAT) to measure implicit automatic concept-attribute associations. Evidences have suggested that Anorexia Nervosa (AN) and Bulimia Nervosa (BN) were characterized by “Ideal Thin” construct.ObjectivesThe aim of this study was the evaluation, at an implicit level, of Ideal Thin construct in a sample of Eating Disorders (ED) patients.MethodsAn “Ideal thin” Implicit Association Tests (Ideal thin IAT) has been modeled, to evaluate the implicit ideal thin in ED patients compared with an healthy control group. IAT test has been administered to a sample composed by 17 AN patients, 14 BN patients, 17 Binge Eating patients (BED) and 32 healthy controls (HC). The target categories, were “OVERWEIGHT / UNDERWEIGHT” and “POSITIVE / NEGATIVE”. Stimuli included pictures of overweight and normal weight models and positive/negative words. A positive IAT effect underlines an implicit tendency to associate the category “UNDERWEIGHT” with negative attributes, instead a negative IAT effect suggest an implicit tendency to associate the same category with positive attributes.ResultsResults showed no significant difference between HC and clinical groups in implicit “Ideal Thin construct”. All groups showed positive IAT effect. No correlations between implicit attitude and clinical variables were found.ConclusionResults show a common implicit tendency generalized in the sample to positively judge underweight. This implicit tendency was stronger in patients with Anorexia Nervosa (0,30), than patents with Bulimia Nervosa (0,41), than Healthy Control (0,42), followed by patients with BED (0,56).

IntroductionGreenwald et al. (1998) developed The implicit Association Test (IAT) to measure automatic concept-attribute associations. Several evidences showed that Eating Disorders (EDs) were charactterized by a low explicit self-esteem.ObjectivesThe first aim was the evaluation of implicit self-esteem in a sample of patients with EDs. Second aim was to verify the correlation between implicit and explicit self-esteem, hypothesizing that they could represent two independent constructs.MethodsA IAT modeled to assess self-esteem (Self-esteem IAT) has been administered to 17 Anorexia Nervosa (AN), 14 Bulimia Nervosa (BN), 17 Binge Eating (BED) patients and 32 healthy controls (HC). In IAT, the target categories were represented by the words «SELF / OTHER» and «agreeable / disagreeable». A positive IAT effect suggest a negative implicit self esteem, instead a negative IAT effect suggest a positive implicit self-esteem. Traditional self reports were used to evaluate explicit self-esteem to all participants.ResultsResults showed a significant difference between HC and clinical groups in implicit self-esteem. HC and BED showed positive IAT effect, instead AN and BN shows a negative IAT effect. No correlations between implicit and explicit self-esteem were found.ConclusionResults showed that HC has a much more positively implicit self-esteem compared to clinical samples. An interesting result concerns the absence of any significant correlation between the implicit and explicit self-esteem, that could suggests that the implicit self-esteem is an independent construct respect to the explicit one.

Research focusing on relationship between perfectionism and self-esteem is rather new and offers various and sometimes contradictory findings. Furthermore, a relationship between perfectionism and implicit self-esteem is still an under- investigated topic. The aim of this study was to explore differences in levels of implicit and explicit self-esteem and self-presentation between positive and negative perfectionists. One hundred and forty undergraduate psychology participants in two time points filled in the Self-Liking and Self- Competence Scale, the Perfectionistic Self-Presentation Scale, the Perfectionism Questionnaire, and the Implicit Associations Test. Results showed a significant difference in self-liking, nondisplay of imperfection, and nondisclosure of imperfection between positive and negative perfectionists. Positive perfectionists scored significantly higher on self-liking, and lower on nondisplay and nondisclosure of imperfection than negative perfectionists did. Positive perfectionists also had significantly higher levels of implicit self-esteem. There was no significant difference in self-competence and perfectionistic self-promotion between positive and negative perfectionists.

The prevalence of obesity has been increased in Qatar, with the transition from healthy to unhealthy dietary habits. Behavioral factors that are associated with obesity are, long-term imbalanced energy intake, high screen time, skipping breakfast and physical inactivity. Changes in body composition and percent body fat (PBF) increase the risk of non-communicable disease. This study is the first study conducted in Qatar to investigate the relationship between dietary patterns and body composition among young females at Qatar University. This cross-sectional study consisted of 766 healthy female students Qatari and non-Qatari aged from 18-26 years randomly selected from different colleges at Qatar University. A validate questionnaire was used in order to collect data about healthy and unhealthy dietary patterns. Anthropometric measurements involved body weight, height, waist-to-height ratio (WHtR), waist circumference (WC), body mass index (BMI) and body composition using “Seca285”, “Seca203” and “InbodyBiospace 720”. Dietary patterns were identified by using factor loading. Linear regression was used to estimate confidence intervals and regression coefficient. More than half of the participants had a normal weight (65.1%), whereas 22.8 % and 12.0% were overweight and obese, respectively. Fat mass, BMI and PBF were slightly increased with age, but there was no significant difference. Factor analysis identified two dietary patterns: unhealthy patterns and healthy patterns. The frequent intake of vegetables and fruits was significant among high PBF female students (p=0.045 and p=0.001, respectively). The frequent intake of fast food was higher for overweight female students but there was no significant difference (p=0.289), whereas, the frequent intake of sweetened beverages was associated with higher significant rate of normal weight among female students (p = 0.009). No significant relation was found between dietary patterns, BMI and PBF. In conclusion, body composition is not significantly associated with healthy and unhealthy eating patterns among young females.

We examined whether Japanese people, 47 junior high school students, 49 undergraduates, and 52 older adults, possessed negative attitudes against blacks and the picture book Little Black Sambo. We assessed the implicit attitude toward the target word pairs, “black/white” and “Sambo/Heidi,” by utilizing a paper-based Implicit Association Test and found that both black and Sambo were associated more negatively than white and Heidi. However, the implicit attitudes assessed with a single-target IAT showed that 67 Japanese students showed positive implicit scores for blacks but with smaller valences. A post hoc analysis revealed that the reading experience of Little Black Sambo did not show a significant difference between the implicit attitudes of those who had and had not read the book.

Introduction: The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. Methods: We included the patients >18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight <25 kg/m2 (Group A), overweight from 25 to <30 kg/m2 (Group B), Class I obesity 30 to <35 kg/m2 (Group C), and ≥35 kg/m2 (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. Results: There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [p = 0.017], Group D vs. Group A [p = 0.001], and Group D vs. Group C [p = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [p = 0.025], Group D vs. Group A [p < 0.001], Group D vs. Group B [p = 0.006], and Group D vs. Group C [p = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [p < 0.001], Group C vs. Group A [p < 0.001], Group D vs. Group A [p < 0.001], Group D vs. Group B [p < 0.001], and Group D vs. Group C [p = 0.010]). Conclusion: COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.

Das28 Remission

Background:Rheumatoid arthritis (RA) is associated with increased body mass index (BMI)- 60% of patients are either overweight or obese. Obesity in RA has been shown to predict reduced response to biologic therapy including tumour-necrosis-factor inhibitors (TNFi) [1]. However, it is not clear whether increased BMI influences response to all TNFi drugs in RA.Objectives:1.To explore whether BMI is associated with response to TNFi in patients with established rheumatoid arthritis (estRA), including those newly-starting on these drugs.Methods:Participants with estRA (>1year since diagnosis) taking biologic medications, registered on METEOR (international database of RA patients), 2008-2013, were included. EULAR response, DAS28 remission (including components), and treatment regimens were recorded at baseline, 6, and 12 months. WHO definitions of overweight (BMI≥ 25) and obese (BMI≥30) were explored as predictors of TNFi response (good EULAR response and DAS28 remission) using normal BMI as comparator. Logistic and linear regression models (controlling for age, gender, smoking, and baseline outcomes) and sensitivity analyses were performed. Subgroup analyses were performed for grouped TNFi and individual TNFi (infliximab, IFX; adalimumab, ADA; etanercept, ETN).Results:247 patients with estRA were taking a biologic at 6 months, and 231 patients were taking a biologic at 12 months. Obese patients taking any biologic were significantly less likely to achieve DAS28 remission (OR 0.33 [95%CI 0.12-0.80]) or good EULAR response (OR 0.37 [95%CI 0.16-0.81]) after 6 months, compared to those of normal BMI; this was also demonstrated in those co-prescribed methotrexate (DAS28 remission: OR 0.23 [95%CI 0.07-0.62]; good EULAR response: OR 0.39 [95%CI 0.15-0.92]). These associations did not remain statistically significant at the 12 months assessment.Regarding specific anti-TNF therapies, RA patients treated with monoclonal antibody (-mab) TNFis (IFX/ADA/ GOL) were significantly less likely to achieve good EULAR response at 6 months if they were obese RA (n=38), compared to those of normal weight (n=44) (OR 0.17 [95%CI 0.03-0.59]). A similar non-significant difference was demonstrated for DAS28 remission, and 12-month remission. Specifically, obese individuals were significantly less likely to achieve good EULAR response at 6 months with IFX (OR 0.09 [95%CI 0.00-0.61]; n=20), and significantly less likely to achieve DAS28 remission at 6 months when newly-starting ADA (OR 0.14 [95%CI 0.01-0.96]; n=17), compared to those of normal weight. There were no significant differences in remission outcomes between individuals of different BMI taking ETN. A small number of individuals stopped taking their respective biologic after 6months; reason for cessation was not recorded.Similar outcomes were seen in patients already established on anti-TNF therapy, with overweight and obese individuals less likely overall to be in DAS28 remission at all time points.Conclusion:In established RA, obesity is associated with reduced treatment response to -mab TNFi. No association between increased BMI and response to ETA was observed. Using BMI to direct biologic drug choice could prove to be a simple and cost-effective personalised-medicine approach to prescribing.References:[1]Schäfer M, Meißner Y, Kekow J, Berger S, Remstedt S, Manger B, et al.

Disparities between the races have been well documented in health and disease in the USA. Recent studies show that telomere length, a marker of aging, is associated with obesity and obesity-related diseases, such as heart disease and diabetes. The current study aimed to evaluate the connection between telomere length ratio, blood pressure, and childhood obesity. The telomere length ratio was measured in 127 children from both European American (EA) and African American (AA) children, aged 6–10 years old. AA children had a significantly high relative telomere to the single copy gene (T/S) ratio compared to EA children. There was no significant difference in the T/S ratio between normal weight (NW) and overweight/obese (OW/OB) groups of either race. Blood pressure was significantly elevated in AA children with respect to EA children. Hierarchical regression analysis adjusted for race, gender, and age expressed a significant relationship between the T/S ratio and diastolic pressure. Low T/S ratio participants showed a significant increase in systolic pressure, while a high T/S ratio group showed an increase in diastolic pressure and heart rate of AA children. In conclusion, our findings show that AA children have high T/S ratio compared to EA children. The high T/S ratio is negatively associated with diastolic pressure.

Abstract Background Personality has been suggested to be an important factor in understanding onset, maintenance, and recovery from eating disorders (ED). The objective of the current study was to evaluate personality style in different ED diagnostic groups as classified in the Diagnostic and Statistical Manual of Mental Disorders, Fifth edition (DSM-5). Methods The overcontrolled, undercontrolled, and resilient personality styles were compared in four groups of patients with EDs: anorexia nervosa restricting (ANr) (n = 34), anorexia nervosa binge eating/purging (ANbp) (n = 31), atypical anorexia nervosa (AAN) (n = 29), and bulimia nervosa (BN) (n = 76). These groups were compared with a group of patients with borderline personality disorder (BPD) (n = 108), and a non-clinical group (NC) (n = 444). Patient data were collected at two outpatient clinics in Uppsala, Sweden. NC control data were collected through convenience sampling. Participants filled out questionnaires assessing personality style. Results The main findings were more pronounced overcontrol reported by the ANr and AAN groups compared with the BN, BPD, and NC groups, and no significant difference in resilience between the ED and the NC groups. Considerable variability of over- and undercontrol was also found within each group. Conclusions The results replicate previous findings when EDs are classified according to current diagnostic criteria (DSM-5). Taking personality styles into account may improve our understanding of certain characteristics in EDs, such as social deficits and rigidity that are attributed to poor treatment outcome.

Background and aimObesity paradox has aroused increasing concern in recent years. However, impact of obesity on outcomes in intracerebral haemorrhage (ICH) remains unclear. This study aimed to evaluate association of body mass index (BMI) with in-hospital mortality, complications and discharge disposition in ICH.MethodsData were from 85 705 ICH enrolled in the China Stroke Center Alliance study. Patients were divided into four groups: underweight, normal weight, overweight and obese according to Asian-Pacific criteria. The primary outcome was in-hospital mortality. The secondary outcomes included non-routine discharge disposition and in-hospital complications. Discharge to graded II or III hospital, community hospital or rehabilitation facilities was considered non-routine disposition. Multivariable logistic regression analysed association of BMI with outcomes.Results82 789 patients with ICH were included in the final analysis. Underweight (OR=2.057, 95% CI 1.193 to 3.550) patients had higher odds of in-hospital mortality than those with normal weight after adjusting for covariates, but no significant difference was observed for patients who were overweight or obese. No significant association was found between BMI and non-disposition. Underweight was associated with increased odds of several complications, including pneumonia (OR 1.343, 95% CI 1.138 to 1.584), poor swallow function (OR 1.351, 95% CI 1.122 to 1.628) and urinary tract infection (OR 1.532, 95% CI 1.064 to 2.204). Moreover, obese patients had higher odds of haematoma expansion (OR 1.326, 95% CI 1.168 to 1.504), deep vein thrombosis (OR 1.506, 95% CI 1.165 to 1.947) and gastrointestinal bleeding (OR 1.257, 95% CI 1.027 to 1.539).ConclusionsIn patients with ICH, being underweight was associated with increased in-hospital mortality. Being underweight and obese can both increased risk of in-hospital complications compared with having normal weight.
