Project description:This study aims to examine the associations between BMI, disordered eating attitude, body dissatisfaction in female adolescents, and descriptive attributes assigned to silhouettes of varying sizes in male and female adolescents, aged 11 to 15, in rural South Africa. Height and weight were measured to determine BMI. Age and sex-specific cut-offs for underweight and overweight/obesity were determined using the International Obesity Task Force cut-offs. Body image satisfaction using Feel-Ideal Discrepancy (FID) scores, Eating Attitudes Test-26 (EAT-26), and perceptual female silhouettes were collected through self-administered questionnaires in 385 adolescents from the Agincourt Health and Socio-Demographic Surveillance System (HSDSS). Participants self-reported their Tanner pubertal stage and were classified as early pubertal (< = Tanner stage 2), and mid to post pubertal (Tanner stage > 2). Mid to post pubertal boys and girls were significantly heavier, taller, and had higher BMI values than their early pubertal counterparts (all p<0.001). The prevalence of overweight and obesity was higher in the girls than the boys in both pubertal stages. The majority (83.5%) of the girls demonstrated body dissatisfaction (a desire to be thinner or fatter). The girls who wanted to be fatter had a significantly higher BMI than the girls who wanted to be thinner (p<0.001). There were no differences in EAT-26 scores between pubertal groups, within the same sex, and between boys and girls within the two pubertal groups. The majority of the boys and the girls in both pubertal groups perceived the underweight silhouettes to be "unhappy" and "weak" and the majority of girls in both pubertal groups perceived the normal silhouettes to be the "best". These findings suggest a need for policy intervention that will address a healthy body size among South African adolescents.

Project description:Intuitive eating (IE) is a pattern of adaptive eating that has been associated with positive psychosocial and physical factors (e.g., positive body image, lower body mass index; BMI). However, BMI has also been negatively associated with body image. Our goal was to evaluate whether IE is uniquely associated with body image, independent of objective weight status (measured BMI). Further, as a secondary aim, this study analyzed potential moderators (BMI, sex, race-ethnicity) in the IE-body image relationship. Data from 136 adults (34 ± 15 years old, 74% female, 56% Caucasian) were analyzed. BMI was objectively measured in-lab. IE was measured with the Intuitive Eating Scale-2. Body image was measured as a Body Concern composite created using the Eating Disorder Examination-Questionnaire (EDE-Q 6.0) Weight and Shape Concern subscales. Demographic factors and covariates were measured via self-report. Regressions revealed that, after controlling for BMI and covariates, Total IE was uniquely associated with Body Concern (β = -0.463, p < .001), as were two of the IE subscales: Unconditional Permission to Eat (Unconditional Permission; β = -0.320, p < .001) and Eating for Physical Rather than Emotional Reasons (Physical Reasons; β = -0.408, p < .001). BMI was also found to be a significant moderator between IE and Body Concern for Total IE (b = 0.071, p = .017), Unconditional Permission (b = 0.067, p = .001), and Physical Reasons (b = 0.038, p = .021), with the negative association between IE and Body Concern being strongest for healthy weight individuals. Greater IE was associated with lower body image concern across the weight spectrum, though this relationship was strongest for healthy weight individuals and attenuated as BMI increased.

Project description:BackgroundRecent studies suggest psychotic and eating disorders can be comorbid and could have shared genetic liability. However, this comorbidity has been overlooked in the epidemiological literature.AimsTo test whether polygenic risk scores (PRS) for schizophrenia are associated with disordered eating behaviours and body mass index (BMI) in the general population.MethodUsing data from the Avon Longitudinal Study of Parents and Children and random-effects logistic and linear regression models, we investigated the association between PRS for schizophrenia and self-reported disordered eating behaviours (binge eating, purging, fasting and excessive exercise) and BMI at 14, 16 and 18 years.ResultsOf the 6920 children with available genetic data, 4473 (64.6%) and 5069 (73.3%) had at least one disordered eating and one BMI outcome measurement, respectively. An s.d. increase in PRS was associated with greater odds of having binge eating behaviours (odds ratio, 1.36; 95% CI 1.16-1.60) and lower BMI (coefficient, -0.03; 95% CI, -0.06 to -0.01).ConclusionsOur findings suggest the presence of shared genetic risk between schizophrenia and binge eating behaviours. Intermediate phenotypes such as impaired social cognition and irritability, previously shown to be positively correlated in this sample with schizophrenia PRS, could represent risk factors for both phenotypes. Shared genetic liability between binge eating and schizophrenia could also explain higher rates of metabolic syndrome in individuals with schizophrenia, as binge eating could be a mediator of this association in drug-naïve individuals. The finding of an association between greater PRS and lower BMI, although consistent with existing epidemiological and genetic literature, requires further investigation.Declaration of interestNone.

Project description:ObjectiveThe distinctiveness and relative clinical significance of overvaluation, dissatisfaction, and preoccupation with body weight/shape remains inconclusive. This study sought to add to the evidence by testing associations between these three body image constructs and indicators of clinical significance.MethodMale and female secondary students (N = 1,666) aged 12-18 years completed a survey that included measures of dissatisfaction with, overvaluation of, and preoccupation with weight/shape, psychological distress, eating disorder behaviors, and basic demographic information. Conditional process analysis was employed to test the independent and mediating effects of overvaluation, dissatisfaction, and preoccupation on distress, dietary restraint, and objective binge eating.ResultsOvervaluation, dissatisfaction, and preoccupation were highly correlated (r = 0.47-0.84). In girls, preoccupation demonstrated the strongest independent and mediating effects on distress, dietary restraint, and binge eating; whereas neither the direct or indirect effects of dissatisfaction on distress and overvaluation on binge eating were significant. Among boys however, the direct and indirect effects of overvaluation, dissatisfaction, and preoccupation on distress and eating disorder behaviors were relatively equal.DiscussionPreoccupation with weight/shape may be particularly clinically significant in girls, whereas all constructs of body image disturbance may be equally clinically significant in boys. The findings are consistent with the view that these constructs, while closely related, are distinct. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:118-126).

Project description:ObjectiveTo analyze the associations between height and BMI categories in a Portuguese representative sample.MethodsThis is a cross-sectional study with a representative sample of 32,644 Portuguese adults (52.4% females). Sociodemographic and lifestyle characteristics were obtained along with self-reported height and weight. We performed generalized linear models to assess the differences in attained height across BMI categories; analyses were adjusted for age, gender, education, family income per month, proxy reporting information, dietary patterns, and smoking.ResultsBMI categories included underweight and normal weight (46.4%), overweight (37.6%), obese class I and II (15.2%), and obese class III (0.8%). Adults with normal weight had a significantly higher height (females +7 cm and males +5 cm) when compared to obese class III. As BMI categories increased, height decreased. In females and males, after adjusting for confounders, estimates of attained height decreased when compared to the unadjusted model (? = -0.049, 95% CI = -0.050; -0.049 and ? = -0.030, 95% CI = -0.031; -0.029, respectively), although they remained still significant.ConclusionOur results suggest a significant difference in attained height between BMI categories. Future intervention programs aiming at preventing overweight and obesity should monitor sociodemographic, health and environmental conditions that affect attained height potential.

Project description:The aim of this study was to assess the impact of inherent aspects of body image, eating behavior and perceived health competence on quality of life of university students. Participants completed the instruments Body Shape Questionnaire (reduced version, BSQ-8B), Male Body Dissatisfaction Scale (reduced version, MBDS-R), Three-Factor Eating Questionnaire (reduced version, TFEQ-18), Perceived Health Competence Scale (bifactorial version, PHCS-B), World Health Organization Quality of Life Questionnaire-Short Form (WHOQoL-bref) and a questionnaire for characterization of sample. Psychometric properties of instruments were previously evaluated by confirmatory factor analysis. A hypothetical model for each sex was developed and tested. In both model surveys the aspects of the body image (BSQ-8B: body shape concern; MBDS-R: musculature and general body appearance), of eating behavior (TFEQ-18: cognitive restriction, emotional eating, and uncontrolled eating) and of the perceived health competence (PHCS-B: expectations of achieving the desired health results and competence in health behaviors) were used as direct predictors on quality of life (WHOQoL-bref). The variables age, medication use for body change, food supplement use for body change, and body mass index (BMI) were inserted in the aspects of the body image. The variables course shift, initial expectation regarding the course, self-reported performance in the course, concomitant work activities to studies, and economic class were inserted into the quality of life. The model surveys were evaluated using structural equation modeling. A level of significance of 5% was used. A total of 2,198 university students (female = 63.5%), including 1,151 Brazilians and 1,047 Portuguese, participated of study (locally representative samples). The average age of women was 20.8 ± 2.4 years and of men was 21.3 ± 3.3 years. The psychometric properties of the instruments were adequate, except for the PHCS, which was adjusted for each sex. The models presented variance explained of 54% and 49% for women and men, respectively. In both sexes, the students' perceived health competence and academic variables contributed significantly to their quality of life, and age, BMI, and medication and supplement use were significant factors relating to how a student views his or her body image. Women's quality of life was associated with body shape concern and emotional eating aspects. Men's quality of life was associated with general body appearance and cognitive restriction aspects. These results can be used to create and implement educational programs to improve quality of life of university students.

Project description:The prevalence of comorbid psychiatric disorders among patients with eating disorders (ED) is higher than the general population. Individuals diagnosed with eating disorders have changes in their body mass index which could promote severe metabolic disruptions. This study aimed (1) to report the prevalence of comorbid psychiatric disorders among a Mexican adolescent sample diagnosed with eating disorders, (2) to compare our results with the prevalence of psychiatric disorders reported from a national survey of mental health of adolescents, (3) to compare the presence of psychiatric comorbidities between ED diagnoses, and (4) to explore the relationship of these comorbidities with the body mass index. In the study, we included 187 Mexican adolescents diagnosed with eating disorders. The psychiatric comorbidities were evaluated using the Mini International Neuropsychiatric Interview for children/adolescents, and a revised questionnaire on eating and weight patterns. We found that 89% of the Mexican adolescents diagnosed with ED had another psychiatric comorbidity. Major depressive disorder (52.40%) and suicide risk (40%) were the most prevalent comorbidities. Attention and deficit hyperactivity disorder (ADHD) prevalence was different between ED diagnosis, and adolescents with binge-eating disorder and ADHD had the higher body mass index. Our results showed that in this sample of Mexican adolescents, the presence of comorbidities could impact body mass index. This emphasizes the importance that clinicians take into consideration the presence of psychiatric comorbidities to achieve an integrative treatment for adolescents diagnosed with ED.

Project description:Body image disturbance has been highlighted as a common characteristic within the development and maintenance of clinical eating disorders (EDs), represented by alterations in an individual's bodily experience. However, whilst the perceptual stability of the sense of body ownership has been investigated in ED patients, the stability of the sense of body agency in those with ED is yet to be examined. Therefore, body ownership and body agency were investigated using the moving rubber hand illusion, alongside measures of explicit and implicit body satisfaction. Furthermore, with evidence demonstrating a direct link between perceptual and cognitive-affective components of body image in the healthy population, the relationship between measures of body perception and body satisfaction was investigated. Results showed that both ED and healthy individuals displayed a similar subjective experience of illusory ownership and agency towards the fake hand, following voluntary movement. However, whilst both groups initially overestimated their own hand width prior to the illusion, the ED group displayed a significant reduction in hand size estimation following the illusion, which was not matched to the same degree in healthy individuals. In addition, ED individuals displayed a significantly lower body satisfaction compared with healthy females, on both an explicit and implicit level. Such implicit outcomes were shown to be driven specifically by a weaker association between the self and attractiveness. Finally, a significant relationship was observed between specific perceptual measures and implicit body satisfaction, which highlights the important link between perceptual and cognitive-affective components of one's body image. Together, such findings provide a useful foundation for further research to study the conditions in which these two components relate with regard to body image and its disturbance, particularly in relation to the prognosis and treatment of EDs.

Project description:BackgroundUnpleasant attention to unfavorable fat may have harmful psychological effects in terms of body dissatisfaction. As a consequence, this may cause abnormal eating regulation. It has been noted that women interested in liposuction self-report more eating problems. As far as we know, there are no prospective studies with standardized instruments providing sufficient data regarding the effects of aesthetic liposuction on various aspects of quality of life. Nevertheless, publications on the effects of eating habits are lacking.MethodsSixty-one consecutive women underwent aesthetic liposuction. Three outcome measures were applied at baseline and at follow-up: the eating disorder inventory, Raitasalo's modification of the Beck depression inventory, and the 15-dimensional general quality of life questionnaire.ResultsThe mean age at baseline was 44 years, and the mean body mass index was 26.0. Thirty-six (59%) women completed all outcome measures with a mean follow-up time of 7 months. A significant improvement from baseline to follow-up was noted in women's body satisfaction, and their overall risk for developing an eating disorder decreased significantly.ConclusionAesthetic liposuction results in a significantly reduced overall risk for an eating disorder in combination with improved body satisfaction.

Project description:Aim: We aimed to explore how a group of classical ballet dancers perceived their eating attitudes and their bodies, with special attention to the potential presence of eating disorders (EDs) symptoms and body image (dis)satisfaction. Methods: A cross-sectional, mixed-method study was conducted on fourteen trained classical ballet dancers (18-30 years old). Their experiences, perceptions, and feelings regarding eating attitudes and body image concerning classical ballet were acquired through qualitative focus groups. The presence of EDs symptoms and perception and (dis)satisfaction with body image was analyzed quantitatively through self-report questionnaires. Results: Participants reported concerning eating attitudes during the focus groups, such as the regular practice of several restrictive popular diets, constant restriction of foods considered "heavy" or "fatty," meal skipping and ignoring signs of hunger, presence of overeating episodes due to stress and anxiety, feeling guilty about breaking their usual diet, classifying foods as "good" and "bad" or "lean" and "fat," and excluding some of those foods from their usual diets. These reports were partially reflected in the questionnaires, with 50% of the ballerinas showing bulimic symptoms indicative of an unusual eating pattern (only two of them with a significant risk index), 7.1% showing symptoms of moderate binge eating, and 14.3% symptoms of EDs in general. Additionally, when considering their bodies in the context of everyday life, participants were satisfied; however, in the "classical ballet" context, they reported feeling dissatisfied with their shape. These findings were in line with results from the Stunkard's Scale, which revealed that 50% of the sample was dissatisfied with their current body shape and 57.1% indicated that their desired body shape was a leaner figure than one they considered healthy. Conclusions: The constant practice of restrictive diets and other weight-loss strategies to achieve a leaner body were associated with symptoms of EDs and body dissatisfaction in this sample. Importantly, the questionnaires used seemed to underestimate the presence of a disordered eating pattern reported by the participants during focus groups. These data could help to inform psychological and nutritional strategies aimed at improving performance, physical and psychological well-being, and quality of life of ballet dancers.
