Disordered Eating Attitudes

The current study used receiver operating characteristic (ROC) curve analysis to examine the accuracy of somatotype components in correctly classifying disordered eating attitudes (DEA) in female dance students. Participants were a sample of 81 female dancers distributed in two groups: beginner training (BT; age (mean ± SD) = 10.09 ± 1.2 years, n = 32) and advanced training (AT; age = 15.37 ± 2.1 years, n = 49). For evaluation of DEA, the Eating Attitudes Test- 26 (EAT-26) questionnaire was used. We defined an EAT-26 score ≥20 as positive for DEA. Somatotype components were calculated using the Heath-Carter anthropometric method. The risk of presenting DEA was 28.1% (n = 9) in the BT group and 6.1% (n = 3) in the AT group. In the BT group, mesomorphy demonstrated moderate–high accuracy in predicting DEA (area under the curve (AUC) = 0.82, 95% confidence interval (CI): 0.64–0.93). The optimal cut-off of 6.34 yielded a sensitivity of 0.77 and a specificity of 0.95. Ectomorphy showed moderate accuracy in predicting DEA (AUC = 0.768, 95% CI: 0.58–0.89). The optimal cut-off of 2.41 yielded a sensitivity of 0.78 and a specificity of 0.78. In the AT group, none of the components demonstrated accuracy in predicting DEA. Somatotype components were good predictors of disordered eating attitudes in the younger dance student group (beginner training). Further research is needed to identify the determinants of these differences between the two groups.

Disordered Eating Attitudes

The present study used receiver operating characteristic (ROC) curve analysis to investigate the accuracy of body composition and raw bioelectrical impedance analysis (BIA) in correctly classifying disordered eating attitudes (DEA) in dance students. Participants were 81 female dancers assigned in two groups: beginner training (BT; age (mean ± SD) = 10.09 ± 1.2 years, n = 32) and advanced training (AT; age = 15.37 ± 2.1 years, n = 49). Fat mass (FM) was estimated by Slaughter’s equation and skeletal muscle with Poortman’s equation. Impedance (Z), resistance (R), reactance (Xc) and phase angle (PhA) were obtained through multifrequency BIA at a frequency of 50 kHz. Fat-free mass (FFM) was assessed using Sun’s equation. For evaluation of DEA, the Eating Attitudes Test-26 (EAT-26) questionnaire was performed. We defined an EAT-26 score ≥ 20 as positive for DEA. Comparisons between groups were performed by a one-way ANOVA test or Kruskall-Wallis test. Spearman’s rank correlation coefficients were performed to assess associations between variables. ROC curve analysis was utilized to test the accuracy of body composition and BIA variables in predicting DEA. In the BT group, Xc and PhA demonstrated high accuracy in predicting DEA with an area under the curve (AUC) of 0.976 (95% confidence interval (CI): 0.85–1.00) and 0.957 (95% CI: 0.82–0.99), respectively, (both p < 0.0001). FFM Sun had an AUC of 0.836 (95% CI: 0.66–0.94) (p < 0.0001) in the BT group and FFM Slaughter was 0.797 (95% CI: 0.66–0.90) (p < 0.001) in the AT group. Reactance and Phase angle were excellent and useful predictors of DEA in the BT group.

Disordered Eating Attitudes

Background Previous research demonstrated a relationship between ON and disordered eating symptoms (eating concern, restraint, cognitive preoccupations about body shape and weight) and disordered eating attitudes (DEA). Since screening for orthorexia nervosa is now part of clinical practice, the measurement instruments to be used must be clinically significant, reliable, valid and sensitive to our target population. The main objective of the present study was to confirm the factor structure of the Arabic version of the ORTO-R using a first sample of Lebanese adults and confirm those results on another sample. The secondary objective was to assess sex differences in terms of ON and DEA, as well as to examine whether symptoms of ON were related to DEA in Lebanese adults. Methods A total of 783 Lebanese adults was selected to participate in this cross-sectional study (January-May 2018) using a proportionate random sample from all Lebanese governorates. Results The mean age of the total sample was 27.78 ± 11.60 years (Min. 18 –Max. 84) (33.5% females) and their mean BMI was 24.36 ± 5.31 kg/m2. All items of the ORTO-R were extracted during the factor analysis and yielded a two-factor solution with Eigenvalues > 1 (variance explained  =  50.07%; KMO = 0.570; Bartlett’s sphericity test p<0.001; αCronbach = 0.755). This factor structure was confirmed by a confirmatory factor analysis; the Maximum Likelihood Chi-Square  =  26.894 and Degrees of Freedom  =  8, which gave a χ2/df  =  3.36. The Tucker Lewis Index (TLI) value was 0.914, whereas the standardized root mean square residual (SRMR) value was 0.032. The root mean square error of approximation (RMSEA) value was 0.077 [95% CI 0.046–0.111] (pclose = 0.07) and comparative fit index (CFI) value was 0.967 respectively, indicating a good fit of the model. There was also no measurement invariance between genders. Female gender was significantly associated with lower ORTO-R scores (more orthorexia nervosa) compared to males (B = -0.65; p = 0.026, 95% CI -1.22- -0.08; ɳ2 = 0.006). However, no significant difference was found between genders in terms of EAT-26 scores (B = 0.23; p = 0.813, 95% CI -1.66–2.12; ɳ2 = 0.0001). Higher ORTO-R scores (lower/ less pathological ON tendencies and behaviors) were significantly related to higher EAT-26 total scores (higher levels of DEA) as well as higher dieting, bulimia and oral control scores in both females (from a weak to a moderate positive correlation) and males (a weak positive correlation). Conclusion This cross-sectional population-based study confirmed the factor structure of the Arabic version of the ORTO-R, demonstrated an association between ON and DEA and revealed more ON among females compared to males.

Disordered Eating Attitudes

Disordered eating attitudes are rapidly increasing, especially among young women in their twenties. These disordered behaviours result from the interaction of several factors, including beauty ideals. A significant factor is social media, by which the unrealistic beauty ideals are popularized and may lead to these behaviours. The objectives of this study were, first, to determine the relationship between disordered eating behaviours among female university students and sociocultural factors, such as the use of social network sites, beauty ideals, body satisfaction, body image and the body image desired to achieve and, second, to determine whether there is a sensitive relationship between disordered eating attitudes, addiction to social networks, and testosterone levels as a biological factor. The data (N = 168) was obtained using validated surveys (EAT-26, BSQ, CIPE-a, SNSA) and indirect measures of prenatal testosterone. The data was analysed using chi-square, Student’s t-test, correlation tests and logistic regression tests. The results showed that disordered eating attitudes were linked to self-esteem (p < 0.001), body image (p < 0.001), body desired to achieve (p < 0.001), the use of social media (p < 0.001) and prenatal testosterone (p < 0.01). The findings presented in this study suggest a relationship between body image, body concerns, body dissatisfaction, and disordered eating attitudes among college women.

Abstract Background In this study, we investigated the possible role of 2 novel biomarkers of synaptic damage, namely, neurogranin and α-synuclein, in Alzheimer disease (AD). Methods The study was performed in a cohort consisting of patients with AD and those without AD, including individuals with other neurological diseases. Cerebrospinal fluid (CSF) neurogranin and α-synuclein levels were measured by sensitive enzyme-linked immunosorbent assays (ELISAs). Results We found significantly increased levels of CSF neurogranin and α-synuclein in patients with AD than those without AD. Neurogranin was correlated with total tau (tTau) and phosphorylated tau (pTau), as well as with cognitive decline, in patients with AD. Receiver operating characteristic (ROC) curve analysis showed good diagnostic accuracy of neurogranin for AD at a cutoff point of 306 pg per mL with an area under the curve (AUC) of 0.872 and sensitivity and specificity of 84.2% and 78%, respectively. Conclusions Our findings support the use of CSF neurogranin as a biomarker of synapsis damage in patients with AD.

Abstract Background The prevalence of disordered eating attitudes and body dissatisfaction based on muscularity and body fat was investigated among male college students in Kuwait with a range of body mass index values including underweight, normal weight, overweight, and obese participants. Methods Data were collected, using the Eating Attitudes Test (EAT-26) and the Bodybuilder Image Grid (BIG), from 400 male undergraduate students (84.8% Kuwaiti nationals) recruited from both public and private universities in Kuwait. An anonymous, self-administered questionnaire was used to determine the prevalence of symptomatology indicative of anorexia nervosa and bulimia nervosa and to examine the associations between body dissatisfaction and muscularity and body fat. Results Most participants were dissatisfied with their current muscle mass and body fat (67.3 and 69%, respectively). Logistic regression analyses produced odds ratios (ORs) demonstrating that students dissatisfied with their muscularity and body fat and those who indicated a desire to decrease both muscularity and body fat had significantly higher odds of being at risk of disordered eating attitudes (OR = 2.241, 95% CI [1.17, 3.6], p = .032, and OR = 1.898, 95% CI [1.214, 2.967], p = .005, respectively). Obese participants also had higher odds of exhibiting disordered eating attitudes (OR = 2.06, 95% CI [1.17, 3.60], p = .011). Conclusion The high proportion of disordered eating attitudes among Kuwaiti college men was associated with high levels of body image dissatisfaction in relation to both body fat and muscularity. High levels of eating disorder symptoms were also linked to obesity.

ABSTRACTLow posaconazole plasma concentrations (PPCs) have been associated with breakthrough invasive fungal infections. We assessed the correlation between pre-steady-state PPCs (obtained between days 3 and 5) and PPCs obtained during steady state in 48 patients with underlying hematological malignancies receiving posaconazole oral-solution prophylaxis. Pre-steady-state PPCs correlated significantly with PPCs obtained at steady state (Spearmanr= 0.754;P< 0.001). Receiver operating characteristic (ROC) curve analysis of pre-steady-state PPCs revealed an area under the curve (AUC) of 0.884 (95% confidence interval [CI], 0.790 to 0.977) for predicting satisfactory PPCs at steady state.

Abstract Purpose The aim of the current study was to investigate the relationship between disordered eating behaviours, level of mindful eating and obesity amongst young female adults. Methods Two hundred and twenty-seven female young adults aged 19-35 living in Famagusta in North Cyprus participated in this current study. Mindful Eating Questionnaire (MEQ) and Eating Attitudes Test (EAT)-26 were used for data collecting through face-to-face interviews. Weight and body composition were obtained by body composition analyser and height were obtained by stadiometer. The measurements of neck circumference (NC), waist circumference (WC), hip circumference (HC) were measured by using a non-stretching tape according to standard techniques. Body mass index (BMI), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were calculated. Results The majority of participants (66.5%) had less than 20 points on the EAT-26. Overall, the participants with BMI below 18.5 kg/m2 had the highest MEQ scores, while the participants with BMI above 30.0 kg/m2 had the lowest MEQ scores (p < 0.05). Similarly, statistical significance was found between the MEQ scores of obese and normal weighted participants (p < 0.05). A significant negative correlation was found between MEQ scores and BMI, fat mass, WHR, WHtR, NC and WC (r=-0.216, p < 0.01; r=-0.234, p < 0.01; r=-172, p < 0.01 and r=-0.244, p < 0.01, r=-0.145, p < 0.05; r=-0.238, p < 0.05, respectively). Conclusion Our findings suggest that there is a negative relationship between the level of mindful eating and BMI. The evidence from this study also suggests a positive relationship between the risk of eating disorders and BMI. Level of Evidence Level V, cross-sectional descriptive study

Objective This study compared the diagnostic performance of alpha-fetoprotein (AFP) and des-gamma-carboxyprothrombin (DCP) in early-stage hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) under different backgrounds. Methods Patients were enrolled and divided in four groups: chronic HBV infection (CHB), liver cirrhosis (LC), early-stage CHB-HCC, and early-stage LC-HCC. Serum AFP and DCP levels were measured. Receiver-operating characteristic (ROC) curve and area under the curve (AUC) analyses were applied to compare the diagnostic performance of DCP and AFP for HCC. Results In total, 200 patients were enrolled, including 48, 64, 33, and 55 patients with CHB, LC, CHB-HCC, and LC-HCC, respectively. ROC curve analysis revealed that the AUCs of AFP, DCP, and their combination in differentiating early-stage LC-HCC from LC were 0.776, 0.758, and 0.786, respectively. The values of these markers in discriminating early-stage CHB-HCC from CHB were 0.828, 0.731, and 0.862, respectively. Conclusions DCP was inferior to AFP in differentiating early-stage CHB-HCC from CHB. However, AFP and DCP displayed similar performance in distinguishing early-stage LC-HCC and LC.

Disordered Eating Attitudes

To explore the prevalence of disordered eating attitudes among the students of the Princess Nourah Bint Abdulrahman University (PNU), in Riyadh, Saudi Arabia. Methods: In this cross-sectional study, 396 (18-24 years) undergraduate students from the PNU were requested to participate, after acquiring their verbal consent. The two-part questionnaire included the demographic and anthropometric data like age, weight and height in the first part, while the assessment of the disordered eating attitudes according to the tools listed in the Eating Attitude Test 26 (EAT-26) were included in the second part. A total score of 20 or more on questions 1-26 was classified as being at risk of eating disorders. The study showed 145 students (36.8%) in all, fell under the class of high level of concern for an eating disorder, registering a score of 20 or higher on the EAT-26. With respect to the EAT score among the BMI categories marked differences were evident on the EAT items, feeling extremely guilty after eating, occupied with a desire to be thinner, burning up calories during exercise, preoccupied with the thought of having fat on my body, eating diet food, feeling uncomfortable after eating sweets and engaging in dieting behavior, having gone on eating binges where I feel I may not be able to stop and feeling that others would prefer if I ate more food and other people think I am too thin. Besides, in comparison to students with normal weight, students who were underweight, overweight, and obese exhibited considerable disparities on the total EAT score. More than one third (36.6%) of females at PNU university, Saudi Arabia had disordered eating attitudes. The present study revealed that female students require awareness regarding proper nutrition.

Objective. The objective of this study was to assess the prevalence of disordered eating and the dietary patterns of young adult female students. Method. 226 young female first and second year students were randomly recruited. The EAT-26 questionnaire was used to measure disordered eating, and the State Trait Anxiety Inventory tool (STAI) to assess anxiety levels. Results. The prevalence of disordered eating (DE group) was quite high and matched previous reported percentages for this age population (18%). DE students showed significantly lower energy intake compared to control group (CON) (1471 ± 357 vs. 1690 ± 563, kcals). Conclusion. Young adult female students show increased tendency towards disordered or restricted eating behaviours. Preventive intervention concerning the negative behaviours may be beneficial for all college students more so to those suffering from anxiety.
