Thirty-two asymptomatic college females were assessed on multiple aspects of body image. Subjects' estimation of the size of three body sites (waist, hips, thighs) was affected by instructional protocol. Emotional ratings, based on how they "felt" about their body, elicited ratings that were larger than actual and ideal size measures. Size ratings based on rational instructions were no different from actual sizes, but were larger than ideal ratings. There were no differences between actual and ideal sizes. The results are discussed with regard to methodological issues involved in body image research. In addition, a working hypothesis that differentiates affective/emotional from cognitive/rational aspects of body size estimation is offered to complement current theories of body image. Implications of the findings for the understanding of body image and its relationship to eating disorders are discussed.

The study of body image-related problems in non-Western countries is still very limited. Thus, this study aims to identify the main influential sources and show how they affect the body image perceptions of Bangkok adolescents. The researcher recruited 400 Thai male and female adolescents in Bangkok, attending high school to freshmen level, ranging from 16-19 years, to participate in this study. Survey questionnaires were distributed to every student and follow-up interviews conducted with 40 students. The findings showed that there are eight main influential sources respectively ranked from the most influential to the least influential: magazines, television, peer group, familial, fashion trend, the opposite gender, self-realization and health knowledge. Similar to those studies conducted in Western countries, more than half of the total percentage was the influence of mass media and peer groups. Bangkok adolescents also internalized Western ideal beauty through these mass media channels. Alike studies conducted in the West, there was similarities in the process of how these influential sources affect Bangkok adolescent body image perception, with the exception of familial source. In conclusion, taking the approach of identifying the main influential sources and understanding how they affect adolescent body image perceptions can help prevent adolescents from having unhealthy views and taking risky measures toward their bodies. More studies conducted in non-Western countries are needed in order to build a cultural sensitive program, catered to the body image problems occurring in adolescents within that particular society.

Predictors of attrition and predictors and moderators of outcome were explored in a transdiagnostic sample of patients who received ten-session cognitive behavioral therapy (CBT-T) for nonunderweight eating disorders. Body image flexibility, a protective positive body image construct, was hypothesized to be a significant moderator. Data from two case series were combined to form a sample of 78 participants who received CBT-T. Baseline measures of body image, negative affect, personality, and motivation (readiness to change and self-efficacy) were included as potential predictors. Global eating disorder psychopathology at each assessment point (baseline, mid- and post-treatment, 1- and 3-month follow-up) was the outcome variable. Predictors of attrition were assessed using logistic regression, and multilevel modeling was applied for predictors and moderators of outcome. Body image flexibility emerged as the strongest predictor and moderator of global eating disorder psychopathology, followed by body image avoidance. Body checking, negative affect, personality beliefs, and self-efficacy were significant predictors of global eating disorder psychopathology. Higher body image flexibility predicted lower global eating disorder psychopathology at every assessment point. Further research is required to replicate findings and explore the benefit of focusing on positive body image in treatment. © 2018 Wiley Periodicals, Inc.

Background In most developing countries, as in Egypt; postmenopausal breast cancer cases are offered a radical form of surgery relying on their unawareness of the subsequent body image disturbance. This study aimed at evaluating the effect of breast cancer surgical choice; Breast Conservative Therapy (BCT) versus Modified Radical Mastectomy (MRM); on body image perception among Egyptian postmenopausal cases. Methods One hundred postmenopausal women with breast cancer were divided into 2 groups, one group underwent BCT and the other underwent MRM. Pre- and post-operative assessments of body image distress were done using four scales; Breast Impact of Treatment Scale (BITS), Impact of Event Scale (IES), Situational Discomfort Scale (SDS), and Body Satisfaction Scale (BSS). Results Preoperative assessment showed no statistical significant difference regarding cognitive, affective, behavioral and evaluative components of body image between both studied groups. While in postoperative assessment, women in MRM group showed higher levels of body image distress among cognitive, affective and behavioral aspects. Conclusion Body image is an important factor for postmenopausal women with breast cancer in developing countries where that concept is widely ignored. We should not deprive those cases from their right of less mutilating option of treatment as BCT. PMID:19678927

Objective To evaluate body image in adolescents with and without craniofacial conditions; and to examine relationships between body image and quality of life. Design Case-control design. Setting A pediatric hospital’s craniofacial center and primary care practices. Participants 70 adolescents with visible craniofacial conditions and a demographically-matched sample of 42 adolescents without craniofacial conditions. Main Outcome Measure Adolescents completed measures of quality of life and body image including satisfaction with weight, facial and overall appearance; investment in appearance (importance of appearance to self-worth); and body image disturbance (appearance-related distress and impairment in functioning). Results Adolescents with craniofacial conditions reported lower appearance investment (p < 0.001) and were more likely to report concerns about facial features (p < 0.02) compared to non-affected youth. Females in both groups reported greater investment in appearance, greater body image disturbance, and lower weight satisfaction compared to males (p < 0.01). Within both groups, greater body image disturbance was associated with lower quality of life (p <0.01). The two groups did not differ significantly on measures of quality of life, body image disturbance, or satisfaction with appearance. Conclusions Body image and quality of life in adolescents with craniofacial conditions are similar to non-affected youth. Relationships between body image and quality of life emphasize that appearance perceptions are important to adolescents’ well-being regardless of whether they have a facial disfigurement. Investment in one’s appearance may explain variations in body image satisfaction and serve as an intervention target particularly for females. PMID:26751907

The effects of exposure to muscular male models among men: exploring the moderating role of gym use and exercise motivation.

Halliwell, Emma; Dittmar, Helga; Orsborn, Amber

2007-09-01

This study examines the effects of exposure to the muscular male body ideal on body-focused negative affect among male gym users and non-exercisers. As hypothesized, the impact of media exposure depended on men's exercise status. Non-exercisers (n = 58) reported greater body-focused negative affect after exposure to images of muscular male models than after neutral images (no model controls), whereas gym users (n = 58) showed a tendency for less body-focused negative affect after the model images than after the control images. Furthermore, the extent to which gym users were motivated to increase strength and muscularity moderated these exposure effects; men who reported stronger strength and muscularity exercise motivation reported a greater degree of self-enhancement after exposure to the muscular ideal. The findings are interpreted with respect to likely differences in motives for social comparisons.

The Role of the Nurse in the Rehabilitation of Patients with Radical Changes in Body Image Due to Burn Injuries

2005-01-01

Summary Burn injuries are among the most serious causes of radical changes in body image. The subject of body image and self-image is essential in rehabilitation, and the nurse must be aware of the issues related to these concepts and take them seriously into account in drafting out the nursing programme. This paper defines certain key words related to body image and discusses the social context of body image. Burn injuries are considered in relation to the way each of these affects the patient's body image. The aim of nursing is defined and the nurse's role in cases of severe changes in body image due to burn injuries is discussed. PMID:21990985

The importance of the function of exercise in the relationship between obligatory exercise and eating and body image concerns.

PubMed

De Young, Kyle P; Anderson, Drew A

2010-01-01

This study tested whether exercising in response to negative affect moderates the association between obligatory exercise and eating and body image psychopathology. Participants (n=226) completed the Eating Disorders Examination-Questionnaire (EDE-Q), Obligatory Exercise Questionnaire (OEQ), and a question assessing whether they ever exercise in response to negative affect. In total, 132 (58.4%) participants endorsed exercising in response to negative affect. Multiple regression analyses revealed significant main effects of negative affect motivated exercise, OEQ total scores, and gender on all four EDE-Q subscales and significant interactions of negative affect motivated exercise and OEQ scores on the Eating Concern, Shape Concern, and Weight Concern scales but not the Restraint scale of the EDE-Q. Obligatory exercisers may not demonstrate elevated eating and body image concerns in the absence of negative affect motivated exercise, providing further support of the importance of the function of exercise.

Whereas the manifestation of body image disturbance in binge eating disorder (BED) has been intensively investigated concerning the cognitive-affective component, with regard to the behavioral and the perceptual components of body image disturbance in BED, research is limited and results are inconsistent. Therefore, the present study assessed body image disturbance in BED with respect to the different components of body image in a sample of obese females (n = 31) with BED compared to obese females without an eating disorder (n = 28). The Eating Disorder Inventory-2, the Eating Disorder Examination-Questionnaire, the Body Image Avoidance Questionnaire and the Body Checking Questionnaire as well as a Digital Photo Distortion Technique based on a picture of each participant taken under standardized conditions were employed. Using two-sample t tests, we found that the participants with BED displayed significantly greater impairments concerning the cognitive-affective component of body image than the control group. Concerning the behavioral component, participants with BED reported more body checking and avoidance behavior than the controls, but group differences failed to reach significance after the Bonferroni corrections. Regarding the perceptual component, a significant group difference was found for the perceived "ideal" figure, with the individuals suffering from BED displaying a greater wish for a slimmer ideal figure than the control group. These results support the assumption that body image disturbance is a relevant factor in BED, similar to other eating disorders.

Impact of a healthy body image program among adolescent boys on body image, negative affect, and body change strategies.

McCabe, Marita P; Ricciardelli, Lina A; Karantzas, Gery

2010-03-01

This study evaluated the effectiveness of a healthy body image program. In total, 421 adolescent boys completed a five-session intervention program or a wait list control group. There were no differences between the intervention and the control group at post-intervention or any of the follow-up times. Boys in the intervention group who were one standard deviation above the mean on body dissatisfaction at baseline, demonstrated a reduction in negative affect in the intervention group at post-test and 6 months follow-up. Prevention programs need to target boys who are at risk of adopting health risk behaviors, rather than being universally applied. Copyright 2009 Elsevier Ltd. All rights reserved.

Body image disturbance represents a central characteristic of anorexia nervosa (AN). Depression and anxiety are the most common mental comorbidities in patients with AN. This study aims to investigate the relationship of body image with symptoms of depression and anxiety during outpatient psychotherapy in AN. Analyses were conducted using the data set of the Anorexia Nervosa Treatment Outpatient Study (ANTOP) randomized controlled trial. The ANTOP study included N = 242 females with AN between 18 and 56 years of age. The trial was designed to compare enhanced cognitive behavioral therapy (CBT-E) and focal psychodynamic therapy (FPT) with optimized treatment as usual (TAU-O) for patients with AN. The analyses on body image dimensions were conducted using measures of correlations and multiple linear regression analyses to assess the relationship and longitudinal prediction of symptoms of depression and anxiety by body image dimensions. Results showed that body image perceptions were significantly associated with symptoms of depression and anxiety in patients with AN at all treatment stages. In addition, body image dimensions at early treatment stages predict depression and anxiety in follow-up measurements. The correlation of symptoms of depression and anxiety by body image perceptions increased along treatment course. The persistence of body image disturbance, while body mass index increases under treatment (persistency effect), may constitute a relevant factor contributing to the course of the most common affective comorbidities of depression and anxiety in patients with AN. Body image disturbances in patients with AN should therefore be explicitly targeted within the specialized psychotherapy of affected patients.

The purposes of this study were to identify correlations between body mass index, body image, and self-esteem in patients with schizophrenia and to analyse the specific factors affecting self-esteem. This study had a descriptive design, utilising a cross-sectional survey. Participants were patients with schizophrenia who were admitted to a mental health facility in South Korea. A total of 180 questionnaires were distributed, and an appropriate total sample size of 167 valid questionnaires was analysed. Self-esteem was significantly correlated with body image, the subscale of appearance orientation, and body areas satisfaction. However, body mass index exhibited no significant correlation with any variable. The variables found to have a significant explanatory power of 21.4% were appearance orientation and body areas satisfaction. The explanatory power of all factors was 33.6%. The self-esteem of patients with schizophrenia was influenced by body mass index and body image. The positive symptoms of schizophrenia can be controlled by medication, whereas negative symptoms can be improved through education and nursing care with medication. Thus, psychiatric nurses should develop education and care programs that contribute to the positive body image and self-esteem of patients with schizophrenia. Copyright © 2017 Elsevier Inc.

Body image in the person with a stoma.

PubMed

Cohen, A

1991-01-01

Body image is the mental picture one has of one's physical being that develops from birth and continues throughout life and is related to different factors affecting its formation and dynamics. A crisis such as the creation of a stoma leads to an alteration in body image and an awareness of the meaning of the change in appearance and function of an individual. The individual's behavior is examined in several domains: physical, mental, emotional, social, sexual, and economical. When one domain is disturbed the others will be influenced. A person's rehabilitation after ostomy surgery is a continuous process of adaptation and is directed toward returning to a normal way of life. Many factors affect this adaptation to an alteration in body image and are relevant to the patient and family. These factors include, but are not limited to, the disease process, treatment(s), and medical and nursing care in the hospital and community. Knowledge about actual and potential problems associated with an alteration in body image enables the nurse to assess the meaning of the alteration in body image for the individual patient and family, provide counseling before and after the surgery, and intervene so that the individual will be able to adapt to an alteration in body image and return to one's previous activities of daily living and lifestyle.

Body temperature is a very useful parameter for diagnosing diseases. There is a definite correlation between body temperature and diseases. We have used Infrared Thermography to study noninvasive diagnosis of peripheral vascular diseases. Temperature gradients are observed in the affected regions of patients with vascular disorders, which indicate abnormal blood flow in the affected region. Thermal imaging results are well correlated with the clinical findings. Certain areas on the affected limbs show increased temperature profiles, probably due to inflammation and underlying venous flow changes. In general the temperature contrast in the affected regions is about 0.7 to 1° C above the normal regions, due to sluggish blood circulation. The results suggest that the thermal imaging technique is an effective technique for detecting small temperature changes in the human body due to vascular disorders. PMID:20126565

Does body image influence the relationship between body weight and breastfeeding maintenance in new mothers?

PubMed

Swanson, Vivien; Keely, Alice; Denison, Fiona C

Obese women have lower breastfeeding initiation and maintenance rates than healthy weight women. Research generally focuses on biomedical explanations for this. Psychosocial factors including body image and well-being after childbirth are less well understood as predictors of breastfeeding. In obese and healthy weight women, we investigated changes in body image between 72 hrs post-delivery and 6-8 weeks post-natal, studying how women's body image related to breastfeeding initiation and maintenance. We also investigated how psychological distress was related to body image. Longitudinal semi-structured questionnaire survey. Body image and psychological distress were assessed within 72 hrs of birth and by postal questionnaire at 6-8 weeks, for 70 obese and 70 healthy weight women initiating exclusive (breastmilk only) breastfeeding or mixed feeding (with formula milk) in hospital. Breastfeeding was re-assessed at 6-8 weeks. Obese women were less likely to exclusively breastfeed in hospital and maintain breastfeeding to 6-8 weeks. Better body image was related to maintaining breastfeeding and to lower post-natal psychological distress for all women, but education level was the most significant predictor of maintenance in multivariate regression including body image and weight status. Body image mediated, but did not moderate the relationship between weight and breastfeeding maintenance. Body image was lower overall in obese women, but all women had low body image satisfaction around childbirth, reducing further at 6-8 weeks. Health professionals should consider women's body image when discussing breastfeeding. A focus on breast function over form may support breastfeeding for all women. Statement of contribution What is already known on this subject? Obesity can negatively affect breastfeeding initiation and maintenance, but there is little information about how psychosocial factors affect this relationship. Body image may be an important factor, but has not been studied in relation to breastfeeding maintenance. What does this study add This article examines the influence of body image on obese and healthy-weight women's breastfeeding maintenance at 6-8 weeks. Different aspects of body image mediated but did not moderate the relationship between weight status and breastfeeding maintenance, but in multivariate regression, maternal education level was the most significant predictor. Obese women had poorer body image and were less likely to maintain breastfeeding; however, for all women, body image became more negative in this postpartum period. Interventions should normalize positive aspects of women's postnatal bodies, including function rather than form. Addressing body concerns could encourage new mothers to maintain breastfeeding, irrespective of weight status. © 2017 The British Psychological Society.

Body image disturbances are a prominent feature of eating disorders (EDs). Our aim was to test and evaluate a computerized assessment of body image (CABI), to compare the body image disturbances in different ED types, and to assess the factors affecting body image. The body image of 22 individuals undergoing inpatient treatment with restricting anorexia nervosa (AN-R), 22 with binge/purge AN (AN-B/P), 20 with bulimia nervosa (BN), and 41 healthy controls was assessed using the Contour Drawing Rating Scale (CDRS), the CABI, which simulated the participants' self-image in different levels of weight changes, and the Eating Disorder Inventory-2-Body Dissatisfaction (EDI-2-BD) scale. Severity of depression and anxiety was also assessed. Significant differences were found among the three scales assessing body image, although most of their dimensions differentiated between patients with EDs and controls. Our findings support the use of the CABI in the comparison of body image disturbances in patients with EDs vs. Moreover, the use of different assessment tools allows for a better understanding of the differences in body image disturbances in different ED types.

Media-portrayed idealized images, body shame, and appearance anxiety.

2005-07-01

This study was designed to determine the effects of media-portrayed idealized images on young women's body shame and appearance anxiety, and to establish whether the effects depend on advertisement type and on participant self-objectification. Participants were 39 female university students. Twenty-four magazine advertisements comprised 12 body-related and 12 non-body-related products, one half of each with, and the other one half without, idealized images. Preexposure and post exposure body shame and appearance anxiety measures were recorded. Appearance anxiety increased after viewing advertisements featuring idealized images. There was also a significant interaction between self-objectification level and idealized body (presence vs. absence). No differences emerged for body-related compared with non-body-related product advertisements. The only result for body shame was a main effect for time. Participants' body shame increased after exposure to idealized images, irrespective of advertisement type. Although our findings reveal that media-portrayed idealized images detrimentally affect the body image of young women, they highlight the individual differences in vulnerability and the different effects for different components of body image. These results are discussed in terms of their implications for the prevention and early intervention of body image and dieting-related disorders. ( Copyright 2005 by Wiley Periodicals, Inc

Seeing, mirroring, desiring: the impact of the analyst's pregnant body on the patient's body image.

PubMed

Yakeley, Jessica

2013-08-01

The paper explores the impact of the analyst's pregnant body on the course of two analyses, a young man, and a young woman, specifically focusing on how each patient's visual perception and affective experience of being with the analyst's pregnant body affected their own body image and subjective experience of their body. The pre-verbal or 'subsymbolic' material evoked in the analyses contributed to a greater understanding of the patients' developmental experiences in infancy and adolescence, which had resulted in both carrying a profoundly distorted body image into adulthood. The analyst's pregnancy offered a therapeutic window in which a shift in the patient's body image could be initiated. Clinical material is presented in detail with reference to the psychoanalytic literature on the pregnant analyst, and that of the development of the body image, particularly focusing on the role of visual communication and the face. The author proposes a theory of psychic change, drawing on Bucci's multiple code theory, in which the patients' unconscious or 'subsymbolic' awareness of her pregnancy, which were manifest in their bodily responses, feeling states and dreams, as well as in the analyst s countertransference, could gradually be verbalized and understood within the transference. Thus visual perception, or 'external seeing', could gradually become 'internal seeing', or insight into unconscious phantasies, leading to a shift in the patients internal object world towards a less persecutory state and more realistic appraisal of their body image.

Weight status and body image perceptions in adolescents: current perspectives.

PubMed

Voelker, Dana K; Reel, Justine J; Greenleaf, Christy

2015-01-01

Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

Factors associated with psychological distress in women with breast cancer-related lymphoedema.

Alcorso, Jessica; Sherman, Kerry A

2016-07-01

Previous research has shown that lymphoedema impacts negatively on an individual, including psychological distress and body image disturbance, particularly for younger women. This study identified psychological factors associated with distress in women with breast cancer-related lymphoedema and determined whether age moderated the specific relationship between body image disturbance and distress. Australian women (n = 166) diagnosed with breast cancer-related lymphoedema were recruited through a community-based breast cancer organisation and lymphoedema treatment clinics. Participants completed an online survey assessing lymphoedema-related cognitions (personal control, perceived treatment effectiveness, and consequences of lymphoedema), perceived ability to self-regulate lymphoedema-related negative affect, body image disturbance, psychological distress (depression, anxiety and stress), and demographic/medical information. Beliefs about the consequences, perceived effectiveness of treatment and controllability of lymphoedema, perceived ability to self-regulate negative affect, body image disturbance, and number of lymphoedema symptoms were correlated with depression, anxiety, and stress scores. Multivariate regression analyses indicated that body image disturbance was significantly associated with depression, anxiety, and stress, and perceived treatment effectiveness was associated with stress. Age was a significant moderator of the relationship between body image disturbance and depression and anxiety, with older women with greater body image disturbance more distressed. Health professionals need to be aware that women diagnosed with lymphoedema are at risk of experiencing psychological distress, particularly arising from body image disturbance and beliefs that treatment cannot control lymphoedema. Furthermore, older women may be at an increased risk of anxiety and depression arising from body image disturbance. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Bell, Beth T; Lawton, Rebecca; Dittmar, Helga

2007-06-01

Music videos are a particularly influential, new form of mass media for adolescents, which include the depiction of scantily clad female models whose bodies epitomise the ultra-thin sociocultural ideal for young women. The present study is the first exposure experiment that examines the impact of thin models in music videos on the body dissatisfaction of 16-19-year-old adolescent girls (n=87). First, participants completed measures of positive and negative affect, body image, and self-esteem. Under the guise of a memory experiment, they then either watched three music videos, listened to three songs (from the videos), or learned a list of words. Affect and body image were assessed afterwards. In contrast to the music listening and word-learning conditions, girls who watched the music videos reported significantly elevated scores on an adaptation of the Body Image States Scale after exposure, indicating increased body dissatisfaction. Self-esteem was not found to be a significant moderator of this relationship. Implications and future research are discussed.

Objectification in Virtual Romantic Contexts: Perceived Discrepancies between Self and Partner Ideals Differentially affect Body Consciousness in Women and Men

PubMed Central

Overstreet, Nicole M.; Quinn, Diane M.; Marsh, Kerry L.

2015-01-01

The current study examined whether exposure to sexually objectifying images in a potential romantic partner's virtual apartment affects discrepancies between people's perception of their own appearance (i.e., self-perceptions) and their perception of the body ideal that is considered desirable to a romantic partner (i.e., partner-ideals). Participants were 114 heterosexual undergraduate students (57 women and 57 men) from a northeastern U.S. university. The study used a 2 (Participant Gender) x 2 (Virtual Environment: Sexualized vs. Non-Sexualized) between-subjects design. We predicted that women exposed to sexually objectifying images in a virtual environment would report greater discrepancies between their self-perceptions and partner-ideals than men, which in turn would contribute to women's body consciousness. Findings support this hypothesis and show that perceived discrepancies account for the relationship between exposure to sexually objectifying images and body consciousness for women but not men. We also found gender asymmetries in objectification responses when each component of perceived discrepancies, i.e., self-perceptions versus perceptions of a romantic partner's body ideal, were examined separately. For men, exposure to muscular sexualized images was significantly associated with their self-perceptions but not their perceptions of the body size that is considered desirable to a romantic partner. For women, exposure to thin sexualized images was significantly associated with their perceptions that a romantic partner preferred a woman with a smaller body size. However, exposure to these images did not affect women's self-perceptions. Implications for gender asymmetries in objectification responses and perceived discrepancies that include a romantic partner's perceptions are discussed. PMID:26594085

The aim of this study was to find out the effects of chemotherapy-related alopecia on body image and quality of life of Turkish women who have cancer with or without headscarves and factors affecting them. This descriptive study was conducted with 204 women who received chemotherapy at the Istanbul University Institute of Oncology, Turkey. The Patient Description Form, Body Image Scale and Nightingale Symptom Assessment Scale were used in data collection. Statistical analyses were performed using descriptive statistics and non-parametric tests. Logistic regression analysis was done to predict the factors affecting body image and quality of life of the patients. No difference was found between women wearing headscarves and those who did not in respect of their body image. However, women who wore headscarves who had no alopecia felt less dissatisfied with their scars, and women not wearing headscarves who had no alopecia have been feeling less self-conscious, less dissatisfied with their appearance. There was difference in terms of quality of life: women wearing headscarves had worse physical, psychological and general well-being than others. Although there were many important factors, multivariate analysis showed that for body image, having alopecia and wearing headscarves; and for quality of life, having alopecia were the variables that had considerable effects.

The Association Between Body Image and Smoking Cessation Among Individuals Living with HIV/AIDS

2007-01-01

Lower smoking cessation rates are associated with body image concerns in the general population. This relationship is particularly important to study in individuals living with HIV/AIDS due to alarmingly high smoking rates and considerable bodily changes experienced with HIV disease progression and treatment. The association between body image and smoking cessation rates was examined among individuals living with HIV/AIDS participating in a smoking cessation intervention. Body image concerns were significantly associated with depression, anxiety, stress, and social support, all variables known to affect cessation rates. However, reduced quit rates were found among individuals reporting elevated and low levels of body image concerns at the end of treatment. These findings suggest a unique relationship between smoking and body image among individuals living with HIV/AIDS. Further research is needed to examine these effects and whether moderate levels of body image concerns in this population reflect realistic body perceptions associated with positive mental health.

An individual's social and marital function, interpersonal relationships, and quality of life may, sometimes be affected by negative body image. This study is aimed at determining the relationship between body image and sexual function in middle-aged women. In this cross-sectional study, 437 middle-aged women, who were referred to various public healthcare centers in Ahvaz, Iran during 2014-2015, were selected. The Female Sexual Function Index (FSFI) and Body Shape Questionnaire (BSQ) were used for data collection. Chi-square, one-way analysis of variance, Spearman's correlation test, and logistic regression analysis were performed for statistical analysis. Approximately 58% of the participants expressed satisfaction with their body image, 35% were mildly dissatisfied, and 7% were moderately dissatisfied with their body image. Body image had a significant negative relationship with sexual satisfaction and sexual function (p=0.005). Furthermore, there was a significant relationship between body image and sexual desire (p=0.022), pain (p=0.001), sexual arousal (p<0.0005), sexual orgasm (p=0.001), and sexual satisfaction (p<0.0005). As the results indicated, body image is an important aspect of sexual health. In this study, women with a positive body image had higher sexual function valuation, compared to women with a negative body image. Also, body shape satisfaction was a predictor of sexual function.

Predictors of changes in body image concerns of Chinese adolescents.

This nine-month prospective study tested the extent to which risk factors implicated in recent accounts of body dissatisfaction predicted changes in body image concerns of adolescent boys and girls in China. A sample of 593 Chinese adolescents (217 boys, 376 girls) completed measures of weight esteem, appearance esteem and physical stature concern in addition to demographics, internalization of attractiveness ideals, negative affect, and appearance pressure, teasing, and comparison at baseline and nine-month follow-up. For girls, initial levels of social comparison, and internalized attractiveness ideals predicted decreases in body esteem over time. Time 1 negative affect contributed to changes in both appearance esteem and weight esteem for boys. Baseline level of stature concerns and reported height were the only predictors of later stature concerns within each sex. In sum, this study suggests specific factors previously implicated in Western accounts also have utility for understanding body image concerns of adolescents in China.

Weight status and body image perceptions in adolescents: current perspectives

Voelker, Dana K; Reel, Justine J; Greenleaf, Christy

Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one’s body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one’s body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed. PMID:26347007

Repeated exposures to thin-idealized body shapes may alter women's perceptions of what normal (e.g., accepted) and ideal (e.g., desired) bodies in a cultural environment look like. The aim of the present study was to investigate whether exposure to thin and round body shapes may change the subsequent esthetic appreciation of others' bodies and the perceptual and cognitive-affective dimensions of self-body image in patients suffering from anorexia nervosa (AN). Thirteen AN patients and 13 matched healthy controls were exposed to pictures of either thin or round unfamiliar body models and, before and after exposure, they were required to either express liking judgments about round and slim figures of unfamiliar bodies (esthetic task) or to adjust distorted pictures of their own body to their perceptual (How do you see yourself?), affective (How do you feel yourself?), metacognitive (How do others see you?) and ideal (How would you like to look like?) body image (self-body adjustment task). Brief exposures to round models increased liking judgments of round figures in both groups. However, only in AN patients, exposure to round models induced an increase in thin figures liking, which positively correlated with their preoccupation with dieting. Furthermore, exposure to round bodies in AN patients, but not in controls, increased the distortion for the perceptual body image and decreased the size of the ideal one. No differences between the two groups were obtained after adaptation to thin models. Our results suggest that AN patients' perception of their own and others' body is more easily malleable by exposure to round figures as compared to controls. Crucially, this mechanism may strongly contribute to the development and maintenance of self-body image disturbances.

Body Image in Adult Women: Moving Beyond the Younger Years

2015-01-01

In spite of copious literature investigating body dissatisfaction and its correlates in adolescents and young adult women, exploration of body image disturbances in adult women remains an underrepresented domain in the literature. Yet, there are many reasons to suspect that body image in adult women both may differ from and possibly be more complex than that of younger women. Adult women face myriad factors influencing body image beyond those delineated in the body image literature on adolescents and young adult women. For instance, aging-related physiological changes shift the female body further away from the thin-young-ideal, which is the societal standard of female beauty. Further, life priorities and psychological factors evolve with age as well. As such, adult women encounter changes that may differentially affect body image across the lifespan. This paper aims to provide an up-to-date review of the current literature on the relationship between body image and associated mental and physical health problems and behaviors in adult women. In addition, we explore factors that may influence body image in adult women. Lastly, we use this review to identify significant gaps in the existing literature with the aim of identifying critical targets for future research. PMID:26052476

Body image concerns during pregnancy are associated with a shorter breast feeding duration.

breast feeding is affected by numerous psycho-social factors. Antenatal concerns such as embarrassment regarding public feeding and the impact of breast feeding upon breast shape are known to lead to artificial milk use. However, although work has explored the relationship between maternal weight and infant feeding, wider body image concerns have not been examined. The aim of the current study was to explore the association between maternal body image concerns during pregnancy upon intended and actual breast feeding duration. a two stage self report questionnaire completed during pregnancy and at six months post partum. mothers were recruited from local mother and infant groups, nurseries and online mother and infant forums. 128 pregnant women completed both stages. phase one: completion of a questionnaire exploring body image during pregnancy (concerns about stretch marks, weight gain and appearance) and planned breast feeding duration during the second/third trimester of pregnancy (body image, weight, intended duration) followed by a second questionnaire measuring actual breast feeding duration and breast feeding experiences. factor analysis revealed three primary body image concerns: pregnancy body image, prospective postnatal body image and dieting during pregnancy. Higher concerns on all three factors were associated with both intended and actual shorter breast feeding duration. Amongst mothers who stopped breast feeding before six months, those with higher body image concerns were more likely to report stopping due to embarrassment or the perceived impact upon their breast shape. The relationship was not explained by maternal weight, although a higher residual weight gain at six months was associated with a shorter breast feeding duration. mothers who are affected negatively by changes to their body during pregnancy may be less likely to plan to or initiate breast feeding potentially due to underlying issues such as embarrassment or perceived impact of feeding upon their appearance. The findings are important to those working with women during pregnancy and the postpartum period in understanding the impact of body image upon intention and ability to initiate and continue breast feeding.

Poor body image is a public health issue. Mothers are a key influence on adolescent girls' body image. This study evaluated an accessible, scalable, low-intensity internet-based intervention delivered to mothers (Dove Self Esteem Project Website for Parents) on mothers' and their adolescent daughters' body image and psychosocial well-being. British mother-daughter dyads (N = 235) participated in a cluster randomized controlled trial (assessment-only control; mothers viewed the website without structured guidance [website-unstructured]; mothers viewed the website via a tailored pathway [website-tailored]). Dyads completed standardized self-report measures of body image, related risk factors, and psychosocial outcomes at baseline, 2 weeks post-exposure, 6-week, and 12-month follow-up. Dyadic models showed that relative to the control, mothers who viewed the website reported significantly higher self-esteem at post-exposure (website-tailored), higher weight esteem at 6-week follow-up (website-tailored), lower negative affect at 12-month follow-up (website-tailored), engaged in more self-reported conversations with their daughters about body image at post-exposure and 6-week follow-up, and were 3-4.66 times more likely to report seeking additional support for body image issues at post-exposure (website-tailored), 6-week, and 12-month (website-tailored) follow-up. Daughters whose mothers viewed the website had higher self-esteem and reduced negative affect at 6-week follow-up. There were no differences on daughters' body image, and risk factors among mothers or daughters, at post-exposure or follow-up. Tailoring website content appeared beneficial. This intervention offers a promising 'first-step' toward improving psychosocial well-being among mothers and daughters. In order to further optimize the intervention, future research to improve body image-related outcomes and to understand mechanisms for change would be beneficial.

Appearance-related attention biases are thought to contribute to body image disturbances. We investigated how preoccupation with body image is associated with attention biases to body size, focusing on the role of social comparison processes and automaticity. Thirty-six women varying on self-reported preoccupation compared their actual body size to size-modified images of either themselves or a figure-matched peer. Amplification of earlier (N170, P2) and later (P3, LPP) ERP components recorded under low vs. high concurrent working memory load were analyzed. Women with high preoccupation exhibited an earlier bias to larger bodies of both self and peer. During later processing stages, they exhibited a stronger bias to enlarged as well as reduced self-images and a lack of sensitivity to size-modifications of the peer-image. Working memory load did not affect these biases systematically. Current findings suggest that preoccupation with body image involves an earlier attention bias to weight increase cues and later over-engagement with own figure. Copyright © 2018 Elsevier B.V.

2010-06-01

The current study investigated the effects of brief exposure to appearance-related media on young girls' body image. One hundred and twenty-one girls aged 3-6 years old participated. Results indicated that exposure did not affect body dissatisfaction or engagement in appearance-related play behaviours. This is the first empirical study to provide support for previous findings that suggest media exposure does not affect body image in young girls. In contrast to older populations, it is possible that young children may adopt the persona of attractive characters with whom they identify rather than comparing themselves to the characters. Although nearly all girls liked the way they looked, self-report data indicated that nearly one-third of the participants would change something about their physical appearance and nearly half of the girls worried about being fat. Exposure to appearance-related media did not exacerbate concerns.

Background Body image is a critical psychosocial issue for cancer patients as they often undergo significant changes to appearance and functioning. In this review article, our primary purpose was to identify empirically-supported approaches to treat body image difficulties of adult cancer patients that can be incorporated into high-quality comprehensive cancer care. Methods We provided an overview of theoretical models of body image relevant to cancer patients, and presented findings from published literature on body image and cancer from 2003–2013. We integrated these data with information from the patient-doctor communication literature to delineate a practical approach for assessing and treating body image concerns of adult cancer patients. Results Body image difficulties were found across patients with diverse cancer sites, and were most prevalent in the immediate postoperative and treatment period. Age, body mass index, and specific cancer treatments have been identified as potential risk factors for body image disturbance in cancer patients. Current evidence supports the use of time-limited cognitive-behavioral therapy interventions for addressing these difficulties. Other intervention strategies also show promise but require further study. We identified potential indicators of body image difficulties to alert healthcare professionals when to refer patients for psychosocial care, and proposed a framework for approaching conversations about body image that can be used by the oncologic treatment team. Conclusions Body image issues affect a wide array of cancer patients. Providers can use available evidence combined with information from the healthcare communication literature to develop practical strategies for treating body image concerns of cancer patients.

GI Joe or Average Joe? The impact of average-size and muscular male fashion models on men's and women's body image and advertisement effectiveness.

Diedrichs, Phillippa C; Lee, Christina

2010-06-01

Increasing body size and shape diversity in media imagery may promote positive body image. While research has largely focused on female models and women's body image, men may also be affected by unrealistic images. We examined the impact of average-size and muscular male fashion models on men's and women's body image and perceived advertisement effectiveness. A sample of 330 men and 289 women viewed one of four advertisement conditions: no models, muscular, average-slim or average-large models. Men and women rated average-size models as equally effective in advertisements as muscular models. For men, exposure to average-size models was associated with more positive body image in comparison to viewing no models, but no difference was found in comparison to muscular models. Similar results were found for women. Internalisation of beauty ideals did not moderate these effects. These findings suggest that average-size male models can promote positive body image and appeal to consumers. 2010 Elsevier Ltd. All rights reserved.

The media's representation of the ideal male body: a cause for muscle dysmorphia?

Leit, Richard A; Gray, James J; Pope, Harrison G

2002-04-01

This study sought to examine the effects of media images on men's attitudes toward their body appearance. A group of college men viewed advertisements showing muscular men, whereas a control group viewed neutral advertisements. Immediately thereafter, participants performed a computerized test of body image perception while unaware of the hypotheses being tested in the study. The students exposed to the muscular images showed a significantly greater discrepancy between their own perceived muscularity and the level of muscularity that they ideally wanted to have. These findings suggest that media images, even in a brief presentation, can affect men's views of their bodies. Copyright 2002 by Wiley Periodicals, Inc.

Short term exposure to attractive and muscular singers in music video clips negatively affects men's body image and mood.

2012-09-01

Viewing idealized images has been shown to reduce men's body satisfaction; however no research has examined the impact of music video clips. This was the first study to examine the effects of exposure to muscular images in music clips on men's body image, mood and cognitions. Ninety men viewed 5 min of clips containing scenery, muscular or average-looking singers, and completed pre- and posttest measures of mood and body image. Appearance schema activation was also measured. Men exposed to the muscular clips showed poorer posttest levels of anger, body and muscle tone satisfaction compared to men exposed to the scenery or average clips. No evidence of schema activation was found, although potential problems with the measure are noted. These preliminary findings suggest that even short term exposure to music clips can produce negative effects on men's body image and mood. Copyright © 2012 Elsevier Ltd. All rights reserved.

Surgery accounts for an important part of the therapeutic arsenal of colorectal cancer treatment. In digestive cancers, ostomy devices induce the loss of anal function and control. This medical appliance generates changes affecting all aspects of patients' lives. This study explores, on the one hand, the psychological impact of colostomy on colorectal cancer patients' quality of life and on the other hand, it analyzes the correlational links between body image, self-esteem and anxiety during the stoma. Thirty-five patients with colorectal cancer participated in the study, divided into 2 subgroups: 23 were carriers of a definitive stoma and the 12 others with a temporary stoma. All completed the Functional Assessment Cancer Therapy (FACT-C), the Body Image Scale (BIS), the State Trait Anxiety Inventory (STAI-Y) and the Self Esteem Scale (ETES). Analysis revealed the quality of life of temporary ostomates is more affected than that of the definitive ones. All three of them, body image, self-esteem and anxiety negatively affect the quality of life regardless of the type of stoma. This study highlights the prevalence of physical self-esteem for temporary ostomy; the role of a good body image and substantial emotional self-esteem for the permanent ostomy. Future studies are required to explore the underlying causes of the acceptance of this equipment and the mediating role of care devices. Copyright © 2018 Société Française du Cancer.

Predictors of vulnerability to reduced body image satisfaction and psychological wellbeing in response to exposure to idealized female media images in adolescent girls.

PubMed

Durkin, Sarah J; Paxton, Susan J

2002-11-01

Predictors of change in body satisfaction, depressed mood, anxiety and anger, were examined following exposure to idealized female advertising images in Grades 7 and 10 girls. Stable body dissatisfaction, physical appearance comparison tendency, internalization of thin ideal, self-esteem, depression, identity confusion and body mass index (BMI) were assessed. One week later, participants viewed magazine images, before and after which they completed assessments of state body satisfaction, state depression, state anxiety and state anger. Participants were randomly allocated to view either images of idealized females (experimental condition) or fashion accessories (control condition). For both grades, there was a significant decrease in state body satisfaction and a significant increase in state depression attributable to viewing the female images. In Grade 7 girls in the experimental condition, decrease in state body satisfaction was predicted by stable body dissatisfaction and BMI, while significant predictors of decreases in the measures of negative affect included internalization of the thin-ideal and appearance comparison. In Grade 10 girls, reduction in state body satisfaction and increase in state depression was predicted by internalization of the thin-ideal, appearance comparison and stable body dissatisfaction. These findings indicate the importance of individual differences in short-term reaction to viewing idealized media images. Copyright 2002 Elsevier Science Inc.

The impact of early shame memories in Binge Eating Disorder: The mediator effect of current body image shame and cognitive fusion.

PubMed

Duarte, Cristiana; Pinto-Gouveia, José

2017-12-01

This study examined the phenomenology of shame experiences from childhood and adolescence in a sample of women with Binge Eating Disorder. Moreover, a path analysis was investigated testing whether the association between shame-related memories which are traumatic and central to identity, and binge eating symptoms' severity, is mediated by current external shame, body image shame and body image cognitive fusion. Participants in this study were 114 patients, who were assessed through the Eating Disorder Examination and the Shame Experiences Interview, and through self-report measures of external shame, body image shame, body image cognitive fusion and binge eating symptoms. Shame experiences where physical appearance was negatively commented or criticized by others were the most frequently recalled. A path analysis showed a good fit between the hypothesised mediational model and the data. The traumatic and centrality qualities of shame-related memories predicted current external shame, especially body image shame. Current shame feelings were associated with body image cognitive fusion, which, in turn, predicted levels of binge eating symptomatology. Findings support the relevance of addressing early shame-related memories and negative affective and self-evaluative experiences, namely related to body image, in the understanding and management of binge eating.

Positive fantasies or negative contrasts: the effect of media body ideals on restrained eaters' mood, weight satisfaction, and food intake.

PubMed

Boyce, Jessica A; Kuijer, Roeline G; Gleaves, David H

2013-09-01

Although viewing media body ideals promotes body dissatisfaction and problematic eating among women (e.g., extreme restraint/overeating), some argue that women only report such negative effects because they think that they are meant to (i.e., demand characteristics). Because restrained eaters are trying to lose weight, they might be vulnerable to such media exposure. However, because of demand characteristics, evidence is mixed. Therefore, we minimized demand characteristics and explored whether media body ideals would trigger restrained eaters to report negative (negative mood, weight dissatisfaction) or positive (positive mood, weight satisfaction) effects. We also hypothesized that this change (negative or positive) would encourage food intake. Restrained and unrestrained eaters (n=107) memorized media or control images. Restrained eaters exposed to media images reported decreased weight satisfaction and increased negative mood, but their food intake was not significantly affected. Perhaps paying advertent attention to the images caused goal-related negative affect, which triggered restraint. Copyright © 2013 Elsevier Ltd. All rights reserved.

The Body Project is a cognitive dissonance-based body image improvement program with ample research support among female samples. More recently, researchers have highlighted the extent of male body dissatisfaction and disordered eating behaviors; however, boys/men have not been included in the majority of body image improvement programs. This study aims to explore the efficacy of a mixed-gender Body Project compared with the historically female-only body image intervention program. Participants included male and female college students (N = 185) across two sites. We randomly assigned women to a mixed-gender modification of the two-session, peer-led Body Project (MG), the two-session, peer-led, female-only (FO) Body Project, or a waitlist control (WL), and men to either MG or WL. Participants completed self-report measures assessing negative affect, appearance-ideal internalization, body satisfaction, and eating disorder pathology at baseline, post-test, and at 2- and 6-month follow-up. Linear mixed effects modeling to estimate the change from baseline over time for each dependent variable across conditions were used. For women, results were mixed regarding post-intervention improvement compared with WL, and were largely non-significant compared with WL at 6-month follow-up. Alternatively, results indicated that men in MG consistently improved compared with WL through 6-month follow-up on all measures except negative affect and appearance-ideal internalization. Results differed markedly between female and male samples, and were more promising for men than for women. Various explanations are provided, and further research is warranted prior to drawing firm conclusions regarding mixed-gender programming of the Body Project. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:591-602). © 2016 Wiley Periodicals, Inc.

The aims of this study were to adapt the Body Image Quality of Life Inventory (BIQLI) into Brazilian Portuguese (BP) and to assess the psychometric properties of the adapted version. Construct validity was assessed by correlating the BIQLI-BP scores with the Rosenberg's Self-Esteem Scale, with Burns Specific Health Scale-Revised (BSHS-R), and with gender, total body surface area burned, and visibility of the scars. Participants were 77 adult burn patients. Cronbach's alpha for the adapted version was .90 and moderate linear correlations were found between body image and self-esteem and between BIQLI-BP scores and two domains of the BSHS-R: affect and body image and interpersonal relationships. The BIQLI-BP showed acceptable levels of reliability and validity for Brazilian burn patients. Copyright © 2013 Wiley Periodicals, Inc.

My 'Fat Girl Complex': a preliminary investigation of sexual health and body image in women of size.

Satinsky, Sonya; Dennis, Barbara; Reece, Michael; Sanders, Stephanie; Bardzell, Shaowen

2013-01-01

Women of size who inhabit non-normative bodies may have different experiences with body image and sexual health than women of average body size. In this exploratory study, we interviewed four women of size recruited from a larger mixed-methodological study of body image and sexuality. Each woman was interviewed twice on topics of body image, sexuality and sexual health. Reconstructive Horizon Analysis was used to analyse the content of the interviews. Women who expressed that their bodies had inherent personal and social value regardless of size did not articulate connections between body size and their sexual health. However, those women who looked externally for validation of their attractiveness struggled with acceptance of their sexuality and bodies and spoke of ways in which their body size and appearance hindered them from having the sexually healthy lives that they wanted. Findings highlight two important components of women's sexual health as participants related them to body image: the right to pleasure and the right to engage only in wanted sexual activity. Participants described how negative body attitudes affected both of these aspects of their sexual health. Interventions targeting weight-based stigma may offer a means of indirectly promoting sexual health and autonomy in women.

The aim of this research was to test the hypothesis that patients' attitudes toward their body affect their capacity to accurately select their existing natural tooth color. Standard validated psychologic assessments were used to determine a person's perception of body image and experience. Oral images were compared with the patients' perceptions of their natural tooth color, which were then compared with the actual tooth color judged by a dental professional. For the vital body dynamic and disliking body experience subscales, women exhibited a significantly more negative attitude toward their bodies than men (P = .000). Patients with a negative attitude toward their body tended to choose a lighter tooth color. The correlation between patients' and the testing physician's choices of color was r = 0.540 for women and r = 0.746 for men. Unhappiness with body image and experience results in poor perception of a patient's own oral image, which in turn results in a patient perceiving that his or her natural tooth color is lighter than that judged by a dental professional. This has clinical implications when trying to achieve patient satisfaction with dental prostheses.

poor body image during pregnancy is a growing issue. Similarly, emerging evidence is suggesting that social media use may increase the risk of poor well-being e.g. depression, anxiety and body image concerns amongst users. Research has not examined how social media use may influence women during pregnancy. The aim of this study was to therefore to explore the relationship between body image during pregnancy and Facebook use. a cross sectional self-report questionnaire. two hundred and sixty nine pregnant women. community groups and online forums. a self-report questionnaire exploring maternal body image, use of Facebook and how mothers perceived Facebook affected their body image. Descriptive statistics were used to explore body image perceptions. Partial correlations (controlling for maternal age, education, parity and gestation) were used to explore the association between Facebook use and body image during pregnancy. negative body image was common in the sample, increased with gestation and was unrelated to pre pregnancy weight. Mothers with a Facebook account had higher body image concerns than those without a Facebook account. Of those with an account, increased Facebook use was associated with increased body image dissatisfaction, particularly in terms of postnatal concerns for how their body would look with 56.5% reporting that they frequently compared their pregnant body to other pregnant women on the site. Facebook access was frequent with 85% of participants checking it at least once per day and the average participant spending over an hour per day on the site. although causality cannot be fully explained, Facebook use may increase mother's risk of poor body image dissatisfaction during pregnancy. Mothers with already poor body image may also be drawn to the site in order to make comparisons of their appearance. the potential impact of Facebook on increasing the risk of, or promoting existing poor body image is an important message for those working to support mothers during pregnancy and the postnatal period. Care should be taken when directing mothers to use the site. Copyright © 2016. Published by Elsevier Ltd.

Body Image and Eating Disorders Among Lesbian, Gay, Bisexual, and Transgender Youth.

PubMed

McClain, Zachary; Peebles, Rebecka

2016-12-01

Adolescence is a crucial period for emerging sexual orientation and gender identity and also body image disturbance and disordered eating. Body image distortion and disordered eating are important pediatric problems affecting individuals along the sexual orientation and gender identity spectrum. Lesbian, gay, bisexual, transgender (LGBT) youth are at risk for eating disorders and body dissatisfaction. Disordered eating in LGBT and gender variant youth may be associated with poorer quality of life and mental health outcomes. Pediatricians should know that these problems occur more frequently in LGBT youth. There is evidence that newer treatment paradigms involving family support are more effective than individual models of care. Copyright © 2016 Elsevier Inc. All rights reserved.

2016-01-01

Purpose Treatment for rectal and anal cancer (RACa) can result in persistent bowel and gastrointestinal (GI) dysfunction. Body image problems may develop over time and exacerbate symptom-related distress. RACa survivors are an understudied group, however, and factors contributing to post-treatment well-being are not well understood. This study examined whether poorer body image explained the relation between symptom severity and psychological distress. Methods Participants (N=70) completed the baseline assessment of a sexual health intervention study. Bootstrap methods tested body image as a mediator between bowel and GI symptom severity and two indicators of psychological distress (depressive and anxiety symptoms), controlling for relevant covariates. Measures included the EORTC-QLQ-CR38 Diarrhea, GI Symptoms, and Body Image subscales and Brief Symptom Index Depression and Anxiety subscales. Results Women averaged 55 years old (SD=11.6), White (79%), and 4-years post-treatment. Greater Depression related to poorer body image (r=−.61) and worse diarrhea (r=.35) and GI symptoms (r=.48). Greater Anxiety related to poorer body image (r=−.42) and worse GI symptoms (r=.45), but not diarrhea (r=.20). Body image mediated the effects of bowel and GI symptoms on Depression, but not on Anxiety. Conclusions Long-term bowel and GI dysfunction are distressing and affect how women perceive and relate to their bodies, exacerbating survivorship difficulties. Interventions to improve adjustment post-treatment should address treatment side effects, but also target body image problems to alleviate depressive symptoms. Reducing anxiety may require other strategies. Body image may be a key modifiable factor to improve well-being in this understudied population. Longitudinal research is needed to confirm findings.

With aging, women's bodies undergo changes that can affect body image perception, yet little is known about body image in midlife. The purpose of this study was to examine associations between body image and depressive symptoms in Caucasian and African-American midlife women from the Study of Women's Health Across the Nation (SWAN) Chicago site. Body image was measured using the Stunkard Adult Female Figure Rating Scale, and a clinically significant level of depressive symptoms was defined as Center for Epidemiologic Studies Depression Scale (CES-D) score of ≥16 (N=405; N=63 (15.6%) with clinically significant levels of depressive symptoms). Differences between perceived actual, perceived ideal, and actual body size and responses to questions concerning weight satisfaction and attractiveness were examined using logistic regression for associations with a CES-D score of ≥16. Women with body image dissatisfaction (odds ratio (OR)=1.91; p=0.04) or who perceived themselves as "unattractive" (OR=7.74; p<0.01) had higher odds of CES-D of ≥16. We found no significant difference by race. Our results were not confounded by BMI. These results suggest that midlife women with poor body image may be more likely to have clinically significant levels of depressive symptoms. Larger prospective studies are needed to better understand this association.

To describe perceptions of prolapse-specific body image in women with symptomatic prolapse. Women with symptomatic pelvic organ prolapse quantification stage ≥ II prolapse participated in semistructured focus groups or self-report questionnaire. Transcripts were independently reviewed and body image themes were identified and confirmed by consensus. Twenty-five women participated in focus groups and 27 in online questionnaires. Transcript analysis revealed 3 central themes and 25 body-image related subthemes. Women living with prolapse were more likely to feel self-conscious, isolated, "different," less feminine, and less attractive. Women often changed sexual intimacy practices because of embarrassment or discomfort, and many avoided intimacy all together. Prolapse greatly affected women's personal and professional activities causing some women to adjust routines or stop activities. Women reported loss of interest in activities, distraction while performing daily/work-related tasks, and embarrassment when asking for help with activities. Themes identified in this qualitative study demonstrate the profound effect of prolapse on a woman's body image. Copyright © 2011 Mosby, Inc. All rights reserved.

“Body image” is more than the visual perception of size and it is probably multidimensional. It is known to influence eating behaviors and self-esteem of adolescents. Although widely studied in developed countries, it has been studied little in Sri Lanka. This study was designed to translate and culturally adapt a tool to assess dimensions of body image in Sri Lankan adolescents. The study was carried out in the Anuradhapura District on school going children in grades nine to eleven. A multidimensional body image questionnaire was translated to Sinhalese language using the nominal group consensus method. The translated version was administered to 278 (114 boys) students after content validation and pre-testing. To assess test-retest reliability, the same questionnaire was administered to the same sample after two weeks. Psychometric properties were assessed using exploratory factor analysis. Three-factor model emerged when dimensions in body image were analysed. Both boys and girls had almost identical factor structure. The three dimensions identified were “affective body image”, “body perception” and “orientation on body size”. All factors had good internal consistency with Cronbach’s alpha > 0.76 and explained more than 56% of the total variance in both sexes. The translated body image questionnaire was a valid and reliable tool which can be used in Sri Lankan adolescents. Both genders had a similar, multidimensional body image construct.

No Effect of Featural Attention on Body Size Aftereffects

2016-01-01

Prolonged exposure to images of narrow bodies has been shown to induce a perceptual aftereffect, such that observers’ point of subjective normality (PSN) for bodies shifts toward narrower bodies. The converse effect is shown for adaptation to wide bodies. In low-level stimuli, object attention (attention directed to the object) and spatial attention (attention directed to the location of the object) have been shown to increase the magnitude of visual aftereffects, while object-based attention enhances the adaptation effect in faces. It is not known whether featural attention (attention directed to a specific aspect of the object) affects the magnitude of adaptation effects in body stimuli. Here, we manipulate the attention of Caucasian observers to different featural information in body images, by asking them to rate the fatness or sex typicality of male and female bodies manipulated to appear fatter or thinner than average. PSNs for body fatness were taken at baseline and after adaptation, and a change in PSN (ΔPSN) was calculated. A body size adaptation effect was found, with observers who viewed fat bodies showing an increased PSN, and those exposed to thin bodies showing a reduced PSN. However, manipulations of featural attention to body fatness or sex typicality produced equivalent results, suggesting that featural attention may not affect the strength of the body size aftereffect.

This research examined whether comparison target moderates the effects of naturally occurring appearance-focused social comparisons on women's affect, appearance esteem, and dieting thoughts. During daily activities, body-satisfied (BS) women and body-dissatisfied (BD) women recorded their comparison targets and reactions to comparison information. For BS women, upward comparisons with peers were associated with more positive affect (PA) and appearance esteem and less guilt than upward comparisons with media images and downward comparisons with peers were associated with less PA than downward comparisons with media images. For BD women, upward comparisons with peers were associated with more appearance esteem and diet thoughts than upward comparisons with media images and downward comparisons with peers were associated with less PA, appearance esteem, and diet thoughts and more guilt than downward comparisons with media images.

"When I feel the worst pain, I look like shit" - body image concerns in persistent pain.

PubMed

Sündermann, Oliver; Rydberg, Karin; Linder, Ludwig; Linton, Steven James

2018-04-17

Persistent pain is a pervasive condition that is often associated with a distorted body image. Most research into pain and body image investigated neural or physiological correlates (e.g. phantom limb pain), and much less is known about the psychological experience of body image changes in response to pain such as appearance concerns. The aim was to examine body image concerns in people with persistent pain, in particular appearance concerns and related coping behaviours and appearance-related emotions such as anger and shame. Design was cross-sectional and data was collected through in-depth semi-structured interviews with people suffering from persistent musculoskeletal pain (n=7; six females; age=19-56), and analysed with inductive thematic analysis (TA). Two main themes were identified: "Relationship to the painful body" and "Dissatisfaction with the body", each containing three subthemes, along with the side-theme "Appearance concerns affected by pain and mood". All participants reported appearance concerns, predominantly about their weight and related coping behaviours such as avoidance of mirrors, exercising or dieting and pain-induced mood changes that were associated with a negative body image. People with persistent pain report appearance concerns, often related to pain-induced negative mood changes, and reduced functioning. It remains unclear to what extent attitudes towards the body change over time in accordance with pain. A wider concept of body image is required, including the perception of reduced functioning, related appraisals (e.g. "I look weak and old") and appearance investment.

Posturographic destabilization in eating disorders in female patients exposed to body image related phobic stimuli.

Human postural control is dependent on the central integration of vestibular, visual and proprioceptive inputs. Psychological states can affect balance control: anxiety, in particular, has been shown to influence balance mediated by visual stimuli. We hypothesized that patients with eating disorders would show postural destabilization when exposed to their image in a mirror and to the image of a fashion model representing their body ideal in comparison to body neutral stimuli. Seventeen females patients attending a day centre for the treatment of eating disorders were administered psychometric measures of body dissatisfaction, anxiety, depression and underwent posturographic measures with their eyes closed, open, watching a neutral stimulus, while exposed to a full length mirror and to an image of a fashion model corresponding to their body image. Results were compared to those obtained by eighteen healthy subjects. Eating disordered patients showed higher levels of body dissatisfaction and higher postural destabilization than controls, but this was limited to the conditions in which they were exposed to their mirror image or a fashion model image. Postural destabilization under these conditions correlated with measures of body dissatisfaction. In eating disordered patients, body related stimuli seem to act as phobic stimuli in the posturographic paradigm used. If confirmed, this has the potential to be developed for diagnostic and therapeutic purposes. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Most men diagnosed with prostate cancer in the USA will survive. Of the many aspects of survivorship affected by prostate cancer, body image receives limited attention despite some indication that it may be important to men with the disease. The present study investigated how body image changes over time and the relations between changes in body image and quality of life (QOL) in men with prostate cancer. In a longitudinal design, patients (N = 74) completed questionnaires before treatment (T1) and at 1 month (T2) and 2 years (T3) following treatment completion. Growth curve modeling indicated that there was no significant change over time in group-level body image scores. However, hormone treatment was associated with a negative trajectory of change over 2 years. Also, analysis of individual difference scores indicated that ≥50% of patients demonstrated change of at least 0.5 standard deviation between time points. Hierarchical regression indicated that change in body image between T1 and T2 was significantly associated with change in QOL between T1 and T3, while controlling for demographic variables, treatment, treatment-related functioning, and general and treatment-specific positive expectations. In predicting change in body image between T1 and T2, treatment-specific positive expectation was the only significant predictor. The present study demonstrates that body image is an important component of the prostate cancer experience. Findings suggest that body image has a meaningful association with QOL among prostate cancer survivors. Copyright © 2012 John Wiley & Sons, Ltd.

Media effects of experimental presentation of the ideal physique on eating disorder symptoms: a meta-analysis of laboratory studies.

Older meta-analyses of the effects of the media's portrayal of the ideal physique have found small effects revealing that exposure to the ideal physique increases body image concerns. These meta-analyses also included correlational, quasi-experimental, and experimental studies, with limited examination of moderators and other relevant outcomes besides body image. We conducted a systematic literature search and identified 33 experimental (i.e., pre and post data for both experimental and control groups) laboratory studies examining the effects of acute exposure to the media's portrayal of the ideal physique on eating disorder symptoms (i.e., body image, positive affect, negative affect, self-esteem, anger, anxiety and depression) and the mechanisms that moderate this effect. Fourteen separate meta-analyses revealed a range of small to moderate effect sizes for change in outcomes from pre to post for both experimental and control groups. Exposure to images of the ideal physique resulted in small effect sizes for increased depression and anger and decreased self-esteem and positive affect. Moderator analyses revealed moderate effect sizes for increased depression and body dissatisfaction among high-risk participants. This meta-analysis makes it clear that media exposure of the ideal physique results in small changes in eating disorder symptoms, particularly with participants at high risk for developing an eating disorder. Further research is needed to examine the longitudinal effects of media exposure of eating disorder symptoms. Copyright © 2012 Elsevier Ltd. All rights reserved.

Although not part of the diagnostic criteria of the DSM-5, body image disturbance seems to be a relevant feature of Binge Eating Disorder (BED) as well as of other eating disorders such as Anorexia Nervosa (AN) or Bulimia Nervosa (BN). Hence, the aim of the present pilot study was to assess the changeability of body image disturbance in a sample of overweight females with BED by a cognitive-behavioral treatment, directly addressing body image disturbance. Overweight females ( N  = 34) with BED were randomized to a manualized body image therapy or a waiting-list control group. The final sample consisted of n  = 15 participants in the intervention group and n  = 19 in the control group due to two drop-outs in the control condition. Before and after the intervention or the waiting period, respectively, participants filled out a questionnaire battery assessing several body image and eating disorder related features. To quantify the perceptual component of body image disturbance, a digital photo distortion technique based on a picture of each participant taken in a standardized suit was applied. In a two-way ANOVA, significant Time × Group interactions were found for eating and shape concerns, drive for thinness, body dissatisfaction, depressiveness and low self-esteem. Follow-up t -tests indicated a significant symptom reduction of a generally high magnitude in the intervention group. No significant changes concerning body checking and the estimations of one's own "real", "felt" and "ideal" body dimensions were found. The strong symptom reduction in the cognitive-affective component of body image disturbance indicates that an exposure-based cognitive-behavioral body image intervention is a promising treatment module for overweight females with BED, but future research with a larger sample size is needed to quantify possible changes in all components of body image.

Body image mediates negative family climate and deteriorating glycemic control for single adolescents with type 1 diabetes.

Glycemic control declines during adolescence, as youth with diabetes struggle with pubertal changes and a changing social world. The present study tests whether body image mediates longitudinal links between family climate and changes in adolescent glycemic control. Mediation was hypothesized for nondating adolescents but not for dating adolescents, because the former are thought to remain more family oriented than the latter. Participants were German adolescents with Type 1 diabetes (51 girls, 58 boys; M = 15.84 years, SD = 1.44). Participants reported body image and family climate. Physicians assayed blood HbA1c levels (M = 8.22%, SD = 1.80%) to measure glycemic control. For nondating adolescents, body image mediated associations between family climate and longitudinal changes in glycemic control. Poorer family climate was associated with poorer body image, which predicted deteriorating glycemic control. For dating adolescents, family climate was unassociated with changes in glycemic control. Nondating adolescents may look to parents for feedback on body image, which affects how they manage the challenges of diabetes. Parents and practitioners alike should be alert to the fact that family climate continues to be an important determinant of adolescent adjustment, particularly for those who have not moved into romantic relationships. We know that body image matters to adolescents, but for some youth, body image may be the difference between health and serious physical problems.

Findings conflict as to whether thin-ideal media affect women's body satisfaction. Meta-analyses of experimental studies reveal small or null effects, but many women endorse appearance-related media pressure in surveys. Using a novel approach, two samples of women (Ns=656, 770) were exposed to bikini models, fashion models, or control conditions and reported the effects of the images their body image. Many women reported the fashion/bikini models made them feel worse about their stomachs (57%, 64%), weight (50%, 56%), waist (50%, 56%), overall appearance (50%, 56%), muscle tone (46%, 52%), legs (45%, 48%), thighs (40%, 49%), buttocks (40%, 43%), and hips (40%, 46%). In contrast, few women (1-6%) reported negative effects of control images. In open-ended responses, approximately one-third of women explicitly described negative media effects on their body image. Findings revealed that many women perceive negative effects of thin-ideal media in the immediate aftermath of exposures in experimental settings. Copyright © 2017 Elsevier Ltd. All rights reserved.

Introduction Body image is an essential aspect of young girls’ self-definition and individual identity which is influenced by various biological, psychological and social factors. Excessive concern about body image, body image misconception are leading to dissatisfaction, disturbed eating patterns, affecting the nutritional status and also leading to depression and anxiety disorders. This concept of body image has been less explored in Indian context, especially among young girls. Aims The objectives of the study were to assess the body image perception among young college going girls, using a visual analog scale and to compare body image perception and satisfaction with their BMI levels and weight changing methods adopted. Materials and Methods An exploratory cross-sectional study was conducted among 63 female students studying BBM course at a private commerce institution in Vijayapur city. Data was collected using a self administered questionnaire containing details of basic socio-demographic information and a validated visual analogue scale. Height was measured by Seca Stadiometer, weight was measured using Digital weighing machine and Body Mass Index levels were calculated. Percentages were calculated for descriptive variables. Chi-square test was applied for analysing categorical variables. Spearman Rank correlation test was applied for analysing ordinal data. Results A 39.7% of participants were underweight and 15.9% were overweight/obese. Majority of underweight and overweight girls (72% and 89%, respectively) perceived themselves as normal weight. Body image satisfaction of participants was found to be significantly associated with their body image perception, mothers’ educational status and also with relatives’ and peer group’s opinions about their body weight. Unhealthy weight changing patterns like skipping meals (13%), increasing quantity and frequency of meals (17%) were reported among study participants Conclusion This exploratory study highlights the gap between young girls’ body image perception and their BMI levels, indicating body image misconception. Lower literacy level of mothers and opinions of relatives and friends significantly influenced body image satisfaction among study participants. Higher percentage of underweight (39.7%) coupled with unhealthy weight changing patterns reportedly adopted by participants (30%) indicates need for further research on this issue, to help inform public health nutrition programmes.

Despite investigations into the rapid increase in eating disorders across diverse ethnic groups, conclusions concerning ethnicity and eating disorders are contradictory. The objective of the present study was to investigate eating attitudes in ethnic Japanese and Caucasian adolescents in Brazil. The influence of body mass index (BMI), menarche and social-affective relationships on the development of eating disorders was also assessed. Questionnaires evaluating the incidence of eating disorders and the influence of social-affective relationships were applied to 544 Japanese-Brazilian and Caucasian adolescent girls: 10 to 11-year-old Japanese-Brazilian (n = 122) and Caucasian (n = 176) pre-menarcheal adolescents, and 16 to 17-year-old Japanese-Brazilian (n = 71) and Caucasian (n = 175) post-menarcheal adolescents. Caucasian girls obtained higher scores on the Eating Attitudes Test (EAT-26), showed greater body image dissatisfaction, dieted more often and had more diet models introduced by their mothers and peers than the Japanese-Brazilian girls. CONCLUSION The Caucasian adolescents overall appeared to be more sensitive to aesthetic and social pressures regarding body image than the Japanese adolescents. The high incidence of EAT-26 scores above 20 in the Caucasian pre-menarcheal group indicates that individual body image concerns are developing at an earlier age. Multiple logistic regression revealed several associations between mother-teen interactions and the development of abnormal eating attitudes.

This experiment investigated how the esthetic judgment of human body and face modulates cognitive and affective processes. We hypothesized that judgments on ugliness and beauty would elicit separable event-related brain potentials (ERP) patterns, depending on the esthetic value of body and faces in both genders. In a pretest session, participants evaluated images in a range from very ugly to very beautiful, what generated three sets of beautiful, ugly and neutral faces and bodies. In the recording session, they performed a task consisting in a beautiful-neutral-ugly judgment. Cognitive and affective effects were observed on a differential pattern of ERP components (P200, P300 and LPC). Main findings revealed a P200 amplitude increase to ugly images, probably the result of a negativity bias in attentional processes. A P300 increase was found mostly to beautiful images, particularly to female bodies, consistent with the salience of these stimuli, particularly for stimulus categorization. LPC appeared significantly larger to both ugly and beautiful images, probably reflecting later, decision processes linked to keeping information in working memory. This finding was especially remarkable for ugly male faces. Our findings are discussed on the ground of evolutionary and adaptive value of esthetics in person evaluation.

Rubber Hand Illusion Affects Joint Angle Perception

PubMed Central

Butz, Martin V.; Kutter, Esther F.; Lorenz, Corinna

2014-01-01

The Rubber Hand Illusion (RHI) is a well-established experimental paradigm. It has been shown that the RHI can affect hand location estimates, arm and hand motion towards goals, the subjective visual appearance of the own hand, and the feeling of body ownership. Several studies also indicate that the peri-hand space is partially remapped around the rubber hand. Nonetheless, the question remains if and to what extent the RHI can affect the perception of other body parts. In this study we ask if the RHI can alter the perception of the elbow joint. Participants had to adjust an angular representation on a screen according to their proprioceptive perception of their own elbow joint angle. The results show that the RHI does indeed alter the elbow joint estimation, increasing the agreement with the position and orientation of the artificial hand. Thus, the results show that the brain does not only adjust the perception of the hand in body-relative space, but it also modifies the perception of other body parts. In conclusion, we propose that the brain continuously strives to maintain a consistent internal body image and that this image can be influenced by the available sensory information sources, which are mediated and mapped onto each other by means of a postural, kinematic body model.

Nobody's perfect: a qualitative examination of African American maternal caregivers' and their adolescent girls' perceptions of body image.

PubMed

Pope, Michell; Corona, Rosalie; Belgrave, Faye Z

2014-06-01

Using semi-structured interviews, we explored African American maternal caregivers' and their adolescent girls' (N=25 dyads) perceptions about the adolescent's body using Grounded Theory. Caregivers and adolescent girls (Mage=13.42) were asked what the adolescent girls liked most/least about their bodies and how peers and media may affect adolescent girls' perceptions. While some adolescent girls reported overall body satisfaction, others described features they would like to change. Belief in God, body acceptance, and appreciation for average/moderate features helped the adolescent girls maintain their positive body image. The body-related messages that adolescent girls received from caregivers and peers included compliments, pressure to lose weight, teasing, and advice. Adolescent girls also reported being either influenced by or skeptical of the images presented in the media. Programs that promote caregiver-adolescent communication about body perceptions and that build on the adolescent girls' media skepticism may prove useful for their health-related attitudes and behaviors.

Focusing on media body ideal images triggers food intake among restrained eaters: a test of restraint theory and the elaboration likelihood model.

PubMed

Boyce, Jessica A; Kuijer, Roeline G

2014-04-01

Although research consistently shows that images of thin women in the media (media body ideals) affect women negatively (e.g., increased weight dissatisfaction and food intake), this effect is less clear among restrained eaters. The majority of experiments demonstrate that restrained eaters - identified with the Restraint Scale - consume more food than do other participants after viewing media body ideal images; whereas a minority of experiments suggest that such images trigger restrained eaters' dietary restraint. Weight satisfaction and mood results are just as variable. One reason for these inconsistent results might be that different methods of image exposure (e.g., slideshow vs. film) afford varying levels of attention. Therefore, we manipulated attention levels and measured participants' weight satisfaction and food intake. We based our hypotheses on the elaboration likelihood model and on restraint theory. We hypothesised that advertent (i.e., processing the images via central routes of persuasion) and inadvertent (i.e., processing the images via peripheral routes of persuasion) exposure would trigger differing degrees of weight dissatisfaction and dietary disinhibition among restrained eaters (cf. restraint theory). Participants (N = 174) were assigned to one of four conditions: advertent or inadvertent exposure to media or control images. The dependent variables were measured in a supposedly unrelated study. Although restrained eaters' weight satisfaction was not significantly affected by either media exposure condition, advertent (but not inadvertent) media exposure triggered restrained eaters' eating. These results suggest that teaching restrained eaters how to pay less attention to media body ideal images might be an effective strategy in media-literary interventions.

A longitudinal study to explain strategies to change weight and muscles among normal weight and overweight children.

PubMed

McCabe, M P; Ricciardelli, L A; Holt, K

2005-12-01

Previous research has indicated that both boys and girls strive for a slim body, with boys having an additional focus on a muscular body build. The current study was designed to evaluate the utility of a biopsychosocial model to explain body image and body change strategies among children. The study evaluated changes over time in body image and strategies to lose weight and increase muscles among 132 normal weight and 67 overweight boys (mean age = 9.23 years) and 158 normal weight and 55 overweight girls (mean age = 9.33 years). The predictive role of BMI, positive and negative affect, self-esteem and perceived sociocultural pressures to lose weight or increase muscle on body image and body change strategies over a 16 month period was evaluated. All participants completed the questionnaire on both occasions. The results demonstrated that both overweight boys and girls were more likely to be dissatisfied with their weight, place more importance on their weight, engage in more strategies to lose weight as well as perceive more pressure to lose weight. Overweight boys and girls were also more likely to report lower levels of self-esteem and positive affect, and higher levels of negative affect, and reported a reduction in their self-esteem over time. Regression analyses demonstrated that among overweight boys, low self-esteem and high levels of perceived pressure to lose weight predicted weight dissatisfaction; for overweight girls, weight dissatisfaction was also predicted by low levels of self-esteem. The implication of these findings in terms of factors contributing to the adoption of health risk behaviors among children is discussed.

"We're stuck with what we've got": The impact of lipodystrophy on body image.

To evaluate the impact of lipodystrophy on body image and how this affects patients' daily lives. Lipodystrophy refers to a group of rare conditions characterised by generalised or partial lack of body fat and is associated with severe metabolic problems, for example, severe insulin resistance, diabetes and pancreatitis. In addition to its metabolic effect, lack of adipose tissue may have a major impact on appearance and cause distressing physical changes. While global research has focused on diagnosis and management, there is no published work investigating the psychological effects of lipodystrophy on body image. Following ethical approval, participants with lipodystrophy were purposively sampled from the National Severe Insulin Resistance Service in Cambridge, UK, and invited to take part in a semi-structured interview. Eleven (10 female, one male) interviews were conducted and digitally recorded. Data were analysed using an inductive thematic approach. Four main themes were identified in the data set; "Always feeling appearance was different," "a better understanding of lipodystrophy is needed," "feeling accepted" and "there's more to lipodystrophy than managing symptoms." Participants spoke of distressing cosmetic effects related to lack of fat tissue and other changes related to lipodystrophy, contributing to negative body image. For some, negative body image led to feelings of worthlessness impacting daily life and adherence to treatment. Psychological support was lacking but desired by participants. Lipodystrophy contributes to negative body image affecting patients' daily lives. Patients wanted psychological support alongside medical management. Further research is needed to determine how best to deliver psychological support and to evaluate its impact on well-being and metabolic management. The effects of rare diseases such as lipodystrophy on appearance can be distressing for patients. Support beyond medical management is needed to improve patients' daily lives and help them to live well with appearance-altering conditions. © 2018 John Wiley & Sons Ltd.

Triple-phase bone image abnormalities in Lyme arthritis

Arthritis is a frequent manifestation of Lyme disease. Limited triple-phase Tc-99m MDP bone imaging of the wrists and hands with delayed whole-body images was performed in a patient with Lyme arthritis. This demonstrated abnormal joint uptake in the wrists and hands in all three phases, with increased activity seen in other affected joints on delayed whole-body images. These findings are nonspecific and have been previously described in a variety of rheumatologic conditions, but not in Lyme disease. Lyme disease should be considered in the differential diagnosis of articular and periarticular bone scan abnormalities.

Recently, several kinds of post-processing image filters which reduce the noise of computed tomography (CT) images have been proposed. However, these image filters are mostly for adults. Because these are not very effective in small (< 20 cm) display fields of view (FOV), we cannot use them for pediatric body images (e.g., premature babies and infant children). We have developed a new noise reduction filter algorithm for pediatric body CT images. This algorithm is based on a 3D post-processing in which the output pixel values are calculated by nonlinear interpolation in z-directions on original volumetric-data-sets. This algorithm does not need the in-plane (axial plane) processing, so the spatial resolution does not change. From the phantom studies, our algorithm could reduce SD up to 40% without affecting the spatial resolution of x-y plane and z-axis, and improved the CNR up to 30%. This newly developed filter algorithm will be useful for the diagnosis and radiation dose reduction of the pediatric body CT images.

Objective Burn injury deformities and obesity have been associated with social integration difficulty and body image dissatisfaction. However, the combined effects of obesity and burn injury in social integration difficulty and body image dissatisfaction are unknown. Methods Adolescent and young adults burn injury survivors were categorized as normal weight (n=47) or overweight and obese (n=21). Burn-related and anthropometric information was obtained from patients' medical records, while validated questionnaires were used to assess the main outcomes and possible confounders. Analysis of covariance and multiple linear regressions were performed to evaluate the objectives of this study. Results Obese and overweight burn injury survivors did not experience increased body image dissatisfaction (12 ± 4.3 vs 13.1 ± 4.4, p = 0.57) or social integration difficulty (17.5 ± 6.9 vs 15.5 ± 5.7, p=0.16) compared to normal weight burn injury survivors. Weight status was not a significant predictor of social integration difficulty or body image dissatisfaction (p=0.19 and p=0.24, respectively). However, mobility limitations predicted greater social integration difficulty (p=0.005) and body image dissatisfaction (p<0.001), while higher weight status at burn was a borderline significant predictor of body image dissatisfaction (p=0.05). Conclusions Obese and overweight adolescents and young adults, who sustained a major burn injury as children, do not experience greater social integration difficulty and body image dissatisfaction compared to normal weight burn injury survivors. Mobility limitations and higher weight status at burn are likely more important factors affecting the long-term social integration difficulty and body image dissatisfaction of these young people.

Obstetric anal sphincter injury is common but the effect on body image is unreported. The aim of this study was to explore patient perceived changes in body image and other psychological aspects in women attending a perineal follow-up clinic. This retrospective study analysed women's responses to a self-reported questionnaire. Consecutive women with anal sphincter injury who attended a United Kingdom Maternity Hospital perineal follow-up clinic between January 1999 and January 2012 were identified and the records obtained and reviewed. Multivariate regression analyses were performed to examine variables influencing self-reported change in body image. Questionnaires and operation notes were analysed from 422 women who attended at a median of four months after delivery. 222 (53%) reported a change in body image with 80 (19%) reporting lower self-esteem and 75 (18%) a change in their personality due to the change in body image. 248 (59%) perceived an anatomical change due to the delivery. Factors associated with increased likelihood of reporting a change in body image were reporting a perceived change in anatomy due to the delivery, adjusted OR 6.11 (3.56-10.49), anal incontinence, OR 1.97 (1.16-3.36), and delivery by forceps, OR 2.59 (1.23-5.43). This is the first study to quantify body image changes in women after anal sphincter injury sustained in childbirth. These were found to be very common, affecting up to 50% of women. The study has several limitations but it does highlight the significant psychosocial problems of negative self-esteem and personality changes associated with a perceived change in body image that has not previously been reported. It also outlines the further research questions that need to be addressed. Copyright © 2017 Elsevier B.V. All rights reserved.

Investigation of body image as a mediator of the effects of bowel and GI symptoms on psychological distress in female survivors of rectal and anal cancer.

Treatment for rectal and anal cancer (RACa) can result in persistent bowel and gastrointestinal (GI) dysfunction. Body image problems may develop over time and exacerbate symptom-related distress. RACa survivors are an understudied group, however, and factors contributing to post-treatment well-being are not well understood. This study examined whether poorer body image explained the relation between symptom severity and psychological distress. Participants (N = 70) completed the baseline assessment of a sexual health intervention study. Bootstrap methods tested body image as a mediator between bowel and GI symptom severity and two indicators of psychological distress (depressive and anxiety symptoms), controlling for relevant covariates. Measures included the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-CR38) Diarrhea, GI Symptoms, and Body Image subscales and Brief Symptom Index Depression and Anxiety subscales. Women averaged 55 years old (SD = 11.6), White (79 %), and were 4 years post-treatment. Greater Depression was related to poorer Body Image (r = -.61) and worse Diarrhea (r = .35) and GI Symptoms (r = .48). Greater Anxiety was related to poorer Body Image (r = -.42) and worse GI Symptoms (r = .45), but not Diarrhea (r = .20). Body Image mediated the effects of bowel and GI symptoms on Depression, but not on Anxiety. Long-term bowel and GI dysfunction are distressing and affect how women perceive and relate to their bodies, exacerbating survivorship difficulties. Interventions to improve adjustment post-treatment should address treatment side effects, but also target body image problems to alleviate depressive symptoms. Reducing anxiety may require other strategies. Body image may be a key modifiable factor to improve well-being in this understudied population. Longitudinal research is needed to confirm findings.

Effects of induced rumination on body dissatisfaction: Is there any difference between men and women?

Rumination is a factor in the development and maintenance of body dissatisfaction. However, no study has yet investigated the impact of the type of rumination on body image. The first aim of this study was to examine whether the induction of analytic-abstract vs. concrete-experiential rumination affects body dissatisfaction following an induction of negative body image. The second objective was to examine gender differences in these effects. Following induction of negative body image, 102 university undergraduates were randomly assigned to one of three experimental conditions-distraction, concrete rumination or abstract rumination. As expected, there were significant main effects of gender and condition, and a significant interaction between gender and condition on change in body dissatisfaction. In women abstract rumination predicted the highest increase in body dissatisfaction, whereas concrete rumination predicted the highest increase in body dissatisfaction in men. Given that our sample consisted of undergraduate students, our findings cannot be generalized to clinical sample suffering from eating disorder. The different types of rumination seem to impact differentially body dissatisfaction in men and women. Copyright © 2018 Elsevier Ltd. All rights reserved.

In vivo social comparison to a thin-ideal peer promotes body dissatisfaction: a randomized experiment.

2005-09-01

Although social comparison with media-portrayed thin-ideal images has been found to increase body dissatisfaction and negative affect, research has not yet tested whether social comparison with attractive peers in the real world produces similar effects. We randomly assigned 119 young women to interact either with a confederate who conformed to the thin ideal or one who conformed to the average body dimensions of women, within the context of an ostensive dating study. Exposure to the thin-ideal confederate resulted in an increase in body dissatisfaction but not negative affect or heart rate. Initial thin-ideal internalization, perceived sociocultural pressure, self-esteem, and observer-rated attractiveness did not moderate these effects. Results suggest that social comparative pressure to be thin fosters body dissatisfaction but may not promote negative affect. 2005 by Wiley Periodicals, Inc.

A Versatile Mounting Method for Long Term Imaging of Zebrafish Development.

PubMed

Hirsinger, Estelle; Steventon, Ben

2017-01-26

Zebrafish embryos offer an ideal experimental system to study complex morphogenetic processes due to their ease of accessibility and optical transparency. In particular, posterior body elongation is an essential process in embryonic development by which multiple tissue deformations act together to direct the formation of a large part of the body axis. In order to observe this process by long-term time-lapse imaging it is necessary to utilize a mounting technique that allows sufficient support to maintain samples in the correct orientation during transfer to the microscope and acquisition. In addition, the mounting must also provide sufficient freedom of movement for the outgrowth of the posterior body region without affecting its normal development. Finally, there must be a certain degree in versatility of the mounting method to allow imaging on diverse imaging set-ups. Here, we present a mounting technique for imaging the development of posterior body elongation in the zebrafish D. rerio. This technique involves mounting embryos such that the head and yolk sac regions are almost entirely included in agarose, while leaving out the posterior body region to elongate and develop normally. We will show how this can be adapted for upright, inverted and vertical light-sheet microscopy set-ups. While this protocol focuses on mounting embryos for imaging for the posterior body, it could easily be adapted for the live imaging of multiple aspects of zebrafish development.

In breast cancer survivors, own body image may change due to physical and psychological reasons, worsening women's living. The aim of the study was to investigate whether body image may affect the functional and quality of life outcomes after a multidisciplinary and educational rehabilitative intervention in sixty women with primary nonmetastatic breast cancer who have undergone conservative surgery. To assess the quality of life was administered The European Organization for Research and Treatment of Cancer Study Group on Quality of Life core questionnaire, while to investigate the psychological features and self-image were administered the following scales: the Body Image Scale, the Hamilton Rating Scale for Depression, and the State-Trait Anxiety Inventory. To assess the recovery of the function of the shoulder were administered: the Disabilities of the Arm, Shoulder, and Hand Questionnaire and the Constant-Murley Score. Data were collected at the baseline, at the end of the intervention, and at 3-month follow-up. We found a general improvement in the outcomes related to quality of life, and physical and psychological features after treatment (P < 0.001). During follow-up period, a higher further improvement in women without alterations in body image in respect of those with an altered self-perception of their own body was found (P = 0.01). In conclusion, the body image may influence the efficacy of a rehabilitative intervention, especially in the short term of follow-up.

In the past, phenomenological research on subjective body experience was characterised by vaguely defined terminology and methodological shortcomings. The term "body image" has been applied heterogeneously in literature in order to describe a variety of bodily phenomena. In this paper, the German terminology applied to the phenomenology of body experiences is described systematically. In developing a systematic terminology the authors refer to scientific evidence as well as recent reviews, and closely adhere to definitions commonly used in English literature. Different perspectives are utilised, particularly anthropological concepts and theories from developmental and self-psychology. Distinct aspects of body experience are described within the context of a network of external determinants and along a continuum between somatic and mental anchor points. Applying the term "body experience" as umbrella term, different aspects are defined: perceptive (body schema/-perceive), affective (body-cathexis), cognitive-evaluative (body-image, body-ego) and body-consciousness. It is emphasized, that the distinct description of functional levels has to be taken as an approximation of the reality of integrated body experience.

Gender differences in the content of cognitive distraction during sex.

Meana, Marta; Nunnink, Sarah E

2006-02-01

This study compared 220 college men and 237 college women on two types of self-reported cognitive distraction during sex, performance- and appearance-based. Affect, psychological distress, sexual knowledge, attitudes, fantasies, experiences, body image, satisfaction, and sexual function were assessed with the Derogatis Sexual Functioning Inventory and the Sexual History Form to determine associations with distraction. Between-gender analyses revealed that women reported higher levels of overall and appearance-based distraction than did men, but similar levels of performance-based distraction. Within-gender analyses revealed that women reported as much of one type of distraction as the other, while men reported more performance- than appearance-based distraction. In women, appearance-based distraction was predicted by negative body image, psychological distress, and not being in a relationship, while performance-based distraction was predicted by negative body image, psychological distress, and sexual dissatisfaction. In men, appearance-based distraction was predicted by negative body image, sexual dissatisfaction and not being in a relationship, while performance-based distraction was predicted by negative body image and sexual dissatisfaction. Investigating the content of cognitive distraction may be useful in understanding gender differences in sexual experience and in refining cognitive components of sex therapy.

Cancer may be localized in a variety of areas in the human body. This localization is associated with significant issues concerning not only therapy and prognosis but also psychological and psychiatric problems that the patient may be confronted with. The psychic impact on the patient is determined to a significant degree by the symbolism the affected organ carries. The symbolic significance of a sick body area triggers emotions and sets in motion self-defence mechanisms. In this way, patients deal with the new psychic reality that cancer creates. Therapeutic choices may include interventions, involving mutilation, which cause disfigurement and major consequences in the body image which result in narcissistic injuries. The phenomenology of anxiety and depressive disorders is connected to the affected body area. The appearance of cancer not only in sexual organs but also in other body areas, may disturb sexual function and therefore lead to sexual disorders. Especially, head and neck are connected with vital functions. This area of the body has had a major impact on psychic reality since early life. Complicated psychic functions have developed in relation to organs of the head and neck. Therefore, localization of cancer in this area leads to individual psychological and psychiatric problems, since eating and breathing are harmed, verbal communication becomes difficult and body image alters. Also, increased incidence of alcohol and nicotine abuse in these patients reflects special aspects of psychic structure and personality. Because of severe somatic symptoms and poor prognosis, lung cancer patients feel hopelessness and helplessness. Patients with gynaecological cancer are confronted with a disease that affects organs like breast and internal female sexual organs associated with femininity, attractiveness and fertility. Dietary habits are often a source of guilt for patients who suffer from cancer of the gastrointestinal tract. Additionally, stomas, as colostomy, affect body image and cause feelings of embarrassment with severe consequences on the patient's sense of wellbeing, his or her daily activities, interpersonal relationships or sexuality. Depressive symptoms often occur in prodromal stages of pancreatic cancer. Depression is a common diagnosis in patients with prostate cancer. Prostatectomy negatively affects patient's self-esteem, because it might be experienced as a threat to his sexual life. Disfigurement is related to skin cancer because of both cancer and surgical procedures. Therefore, it is a challenge for modern psycho-oncology to identify those patients who are vulnerable in developing psychiatric symptoms, to early diagnose anxiety and depression and to use psychotherapeutic interventions targeting individual psychological and psychiatric problems in relation to the localization of disease in the human body.

This study was designed to probe the psychological factors adolescent orthodontic patients, the role of body image and self-esteem in the whole process of orthodontic treatment and the impact on the efficacy and satisfaction of orthodontic. Five hundred and twenty-eight patients were selected in this study. The Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC) , Rosenberg Self-Esteem Scale (SES), Negative Physical Self-General (NPS-G) and other body analysis scale study after orthodontic lasted 18-24 months were used to investigate the role of body image in adolescent orthodontic treatment. Esthetic evaluation of patients teeth after correction had been significantly improved, patient self-evaluation difference IOTN-AC doctor evaluation, Psychosocial Impact of Dental Aesthetics Questionnaire-tooth confidence, aesthetic concerns, psychological impact and social function were significantly improved. The improvement of the dental aesthetics component (T2 when doctors evaluate IOTN-AC) was positively correlated with the evaluation of the efficacy, and was significantly negatively correlated with the negative emotions of patients at baseline. Negative body image-dental dissatisfied-cognitive component and the affective component, the overall negative body image and negative emotions can predict patient satisfaction with treatment efficacy. Orthodontic treatment not only improves the self-aesthetic evaluation of adolescent patients, but also has a positive effect on the mental health of adolescent patients.

Ethical issues surrounding the use of images from donated cadavers in the anatomical sciences.

PubMed

Cornwall, Jon; Callahan, David; Wee, Richman

2016-01-01

Body donor programs rely on the generosity and trust of the public to facilitate the provision of cadaver resources for anatomical education and research. The uptake and adoption of emerging technologies, including those allowing the acquisition and distribution of images, are becoming more widespread, including within anatomical science education. Images of cadavers are useful for research and education, and their supply and distribution have commercial potential for textbooks and online education. It is unclear whether the utilization of images of donated cadavers are congruent with donor expectations, societal norms and boundaries of established public understanding. Presently, no global "best practices" or standards exist, nor is there a common model requiring specific image-related consent from body donors. As ongoing success of body donation programs relies upon the ethical and institutional governance of body utilization to maintain trust and a positive relationship with potential donors and the community, discussions considering the potential impact of image misuse are important. This paper discusses the subject of images of donated cadavers, commenting on images in non-specific use, education, research, and commercial applications. It explores the role and significance of such images in the context of anatomical science and society, and discusses how misuse - including unconsented use - of images has the potential to affect donor program success, suggesting that informed consent is currently necessary for all images arising from donated cadavers. Its purpose is to encourage discussion to guide responsible utilization of cadaver images, while protecting the interests of body donors and the public. © 2015 Wiley Periodicals, Inc.

Fenwick, Andrea Siân; Sullivan, Karen Anne

2011-09-30

This study aimed to explore the manifestation of body dysmorphic disorder symptoms in a sample of people with eating disorders and to investigate possible associations between body dysmorphia and alexithymia. Forty patients currently seeking treatment for an eating disorder completed a battery of six measures assessing alexithymia, mood, eating behaviours, weight-related body image, body dysmorphia and non-weight related body image. Significant moderate positive correlations (Pearson's r) between selected variables were found, suggesting that participants with high levels of dysmorphic concern (imagined ugliness) have more difficulty with the affective elements of alexithymia, that is, identifying and describing feelings. When depression, eating attitudes, and weight-related body image concerns were controlled for, significant moderate positive correlations between this alexithymia factor and dysmorphic concerns remained present. An independent-samples t-test between eating-disordered participants with and without symptoms of body dysmorphic disorder (BDD) revealed significant group differences in difficulties identifying feelings. This pattern of results was replicated when the groups were identified on the basis of dysmorphic concerns, as opposed to BDD symptoms. This study highlights the associations between alexithymia and body dysmorphia that have not previously been demonstrated. Copyright © 2011 Elsevier Ltd. All rights reserved.

Body image issues in women with breast cancer.

Diagnosis and treatment of breast cancer affects women physically as well as psychologically. There are many obvious and real factors that are related to psychological distress in women coping with breast cancer, such as facing a life-threatening illness, painful and impairing treatments, and significant role changes. Although these factors are clearly important, issues related to body image in women faced with breast cancer can also add to psychological distress. Women, in general, are concerned with their appearance, their weight, and their body, with recent studies suggesting 89% of women reported concerns with weight. Such premorbid concerns are often deeply ingrained and can contribute to psychological distress in women treated for breast cancer. The present article is a summary of the literature that has examined body image issues and related psychological adjustment in women with breast cancer. Implications for clinical practice and recommendations for future investigations are discussed.

The effects of "thin ideal" media on women's body image concerns and eating-related intentions: the beneficial role of an autonomous regulation of eating behaviors.

PubMed

Mask, Lisa; Blanchard, Céline M

2011-09-01

The present study examines the protective role of an autonomous regulation of eating behaviors (AREB) on the relationship between trait body dissatisfaction and women's body image concerns and eating-related intentions in response to "thin ideal" media. Undergraduate women (n=138) were randomly assigned to view a "thin ideal" video or a neutral video. As hypothesized, trait body dissatisfaction predicted more negative affect and size dissatisfaction following exposure to the "thin ideal" video among women who displayed less AREB. Conversely, trait body dissatisfaction predicted greater intentions to monitor food intake and limit unhealthy foods following exposure to the "thin ideal" video among women who displayed more AREB.

The effects of advertisements that sexually objectify women on state body dissatisfaction and judgments of women: The moderating roles of gender and internalization.

PubMed

Krawczyk, Ross; Thompson, J Kevin

2015-09-01

Experimental studies have demonstrated that exposure to idealized images of women increases state body image disturbance. However, little work has experimentally examined the effects of exposure to images that sexually objectify women, especially as it relates to women and men's state body dissatisfaction and judgments of women. In the current study, 437 women and men were randomly assigned to view advertisements that sexually objectify women and portray appearance ideals, or to view non-appearance-related advertisements. Results indicated that state body dissatisfaction increased for women and men exposed to advertisements that sexually objectified women, although this effect was larger for women. Trait internalization of appearance ideals moderated this effect, indicating that women and men with higher internalization exhibited greater state body dissatisfaction after viewing women sexually objectified in advertisements. Exposure to women sexually objectified in advertisements did not affect women's or men's attractiveness or competence ratings of women in university advertisements. Copyright © 2015 Elsevier Ltd.

2016-01-01

Gender information has many useful applications in computer vision systems, such as surveillance systems, counting the number of males and females in a shopping mall, accessing control systems in restricted areas, or any human-computer interaction system. In most previous studies, researchers attempted to recognize gender by using visible light images of the human face or body. However, shadow, illumination, and time of day greatly affect the performance of these methods. To overcome this problem, we propose a new gender recognition method based on the combination of visible light and thermal camera images of the human body. Experimental results, through various kinds of feature extraction and fusion methods, show that our approach is efficient for gender recognition through a comparison of recognition rates with conventional systems.

Functional brain imaging has identified specialized neural systems supporting human body perception. Responses to nude vs. clothed bodies within this system are amplified. However, it remains unresolved whether nude and clothed bodies are processed by same cerebral networks or whether processing of nude bodies recruits additional affective and arousal processing areas. We recorded simultaneous MEG and EEG while participants viewed photographs of clothed and nude bodies. Global field power revealed a peak ∼145ms after stimulus onset to both clothed and nude bodies, and ∼205ms exclusively to nude bodies. Nude-body-sensitive responses were centered first (100-200ms) in the extrastriate and fusiform body areas, and subsequently (200-300ms) in affective-motivational areas including insula and anterior cingulate cortex. We conclude that visibility of sexual features facilitates early cortical processing of human bodies, the purpose of which is presumably to trigger sexual behavior and ultimately ensure reproduction.

Colautti, Lauren A; Fuller-Tyszkiewicz, Matthew; Skouteris, Helen; McCabe, Marita; Blackburn, Stephen; Wyett, Elise

2011-09-01

The present study evaluated whether the strength of relationship between contextual cues (presence of company and mood) and state body dissatisfaction varied as a function of individual differences in key trait measures (body shame, body surveillance tendencies, internalization of appearance standards, and trait affect) which have been linked to trait body dissatisfaction. Fifty-five undergraduate women completed a questionnaire containing the trait-based measures and then carried a Personal Digital Assistant (PDA) for a 7-day period. The PDA prompted participants six times daily to self-report their current mood and state body dissatisfaction. Multi-level modeling revealed that individual differences in body shame predicted inter-individual variability in the strength of the relationships between presence of company and state body dissatisfaction, and positive mood and state body dissatisfaction. Trait positive affect also explained variance in the positive mood state-body dissatisfaction relationship. The implications of the findings for prevention of body image disturbances are discussed.

Beauty and the beast: Psychobiologic and evolutionary perspectives on body dysmorphic disorder.

PubMed

Stein, Dan J; Carey, Paul D; Warwick, James

2006-06-01

Body dysmorphic disorder (BDD) is characterized by preoccupation with a defect in appearance. Concepts of beauty play a particularly crucial role in humans' mental and social life, and may have specific psychobiologic and evolutionary underpinnings. In particular, there is a growing literature on the neurocircuitry underpinning the body schema, body image and facial expression processing, and aesthetic and symmetry judgments. Speculatively, disruptions in cognitive-affective processes relevant to judgements about physical beauty lead to BDD.

Body image and gestational weight gain: a prospective study.

2013-01-01

Approximately 50% of Australian adult women of childbearing age are overweight or obese, and, when pregnant, the majority gain excessive weight; this is also the case in the United States and other developed nations. High gestational weight gain (GWG) is the strongest predictor of maternal overweight/obesity postbirth and is also associated with an increased risk of childhood obesity. Understanding factors that contribute to excessive GWG is vital in combating obesity. The aim of the current study was to examine whether body image attitudes (eg, feeling fat, attractive, or strong and fit, and salience of weight and shape) predict GWG. Pregnant women, recruited through advertisements on pregnancy online forums and parenting magazines, completed questionnaires assessing body image, demographic variables, and GWG. The Body Attitudes Questionnaire assessed body image in early-to-middle, middle, and late pregnancy (mean of 16.8, 24.7, and 33.0 weeks' gestation, respectively). Total GWG was calculated by subtracting self-reported pre pregnancy weight from self-reported weight at 36.8 weeks' gestation. A total of 150 pregnant women responded to the study's advertisements, and 72% (n = 108) took part. After controlling for pre pregnancy body mass index (BMI), lower attractiveness in early-to-middle pregnancy was associated with higher GWG. In late pregnancy, women who had the lowest feelings of fatness had greater GWG. Body image attitudes earlier in pregnancy did not predict whether GWG recommendations were exceeded. Women of higher BMI were more likely to gain excessive weight. The findings suggest that the type and timing of pregnancy, body attitudes, and the time of pregnancy when they are noted, predict GWG. However, more research in the area is needed, including assessment of the relationship between body image concerns, GWG, and other psychosocial factors. We recommend that midwives monitor body image concerns in pregnancy to help address factors affecting GWG in at-risk women. © 2013 by the American College of Nurse-Midwives.

Body self. Development, psychopathologies, and psychoanalytic significance.

PubMed

Krueger, D W

2001-01-01

Ego development or, more broadly, the sense of self has at its core a cohesive, distinct, and accurate body self. Compromise of body self development as a result of early overstimulation, empathic unavailability or nonresponse of the caretaker, and inconsistency or selectivity of response can lead to specific developmental arrests, including body-image distortions, nonintegration of body self and psychological self, and difficulties in the regulation of tension states and affect. The individual may then attempt to repair those disrupted developmental needs by such symptomatic expressions as eating disorders, compulsive exercise, substance abuse, and the creation of physical danger, as a step toward integration of mind and body as well as a defensive antidote to painful affect. In the psychoanalytic treatment of these patients, the need for the analyst's attunement to the patient's development of body self as well as psychological self development is illustrated by clinical vignettes of the enactments and attempted restitution of specific developmental trauma.

Can We Distinguish Emotions from Faces? Investigation of Implicit and Explicit Processes of Peak Facial Expressions.

2016-01-01

Most previous studies on facial expression recognition have focused on the moderate emotions; to date, few studies have been conducted to investigate the explicit and implicit processes of peak emotions. In the current study, we used transiently peak intense expression images of athletes at the winning or losing point in competition as materials, and investigated the diagnosability of peak facial expressions at both implicit and explicit levels. In Experiment 1, participants were instructed to evaluate isolated faces, isolated bodies, and the face-body compounds, and eye-tracking movement was recorded. The results revealed that the isolated body and face-body congruent images were better recognized than isolated face and face-body incongruent images, indicating that the emotional information conveyed by facial cues was ambiguous, and the body cues influenced facial emotion recognition. Furthermore, eye movement records showed that the participants displayed distinct gaze patterns for the congruent and incongruent compounds. In Experiment 2A, the subliminal affective priming task was used, with faces as primes and bodies as targets, to investigate the unconscious emotion perception of peak facial expressions. The results showed that winning face prime facilitated reaction to winning body target, whereas losing face prime inhibited reaction to winning body target, suggesting that peak facial expressions could be perceived at the implicit level. In general, the results indicate that peak facial expressions cannot be consciously recognized but can be perceived at the unconscious level. In Experiment 2B, revised subliminal affective priming task and a strict awareness test were used to examine the validity of unconscious perception of peak facial expressions found in Experiment 2A. Results of Experiment 2B showed that reaction time to both winning body targets and losing body targets was influenced by the invisibly peak facial expression primes, which indicated the unconscious perception of peak facial expressions.

It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. Monocentric, prospective, longitudinal cohort study. Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery. Influence of gender, age, and type of procedure, either laparoscopic sleeve gastrectomy (SG) or laparoscopic Roux-en-Y gastric bypass, were analyzed. Thirty patients completed the questionnaires before and within 6 and 24 months after surgery. SF-36 physical summary score improved significantly from 34.3±11.0 before surgery to 46.0±10.4 within 6 months (P<.001) and to 49.8±8.2 within 24 months (P<.001) after surgery. SF-36 mental summary score improved significantly from 42.1±14.7 before surgery to 52.3±8.4 within 6 months (P<.001) and to 48.4±12.2 within 24 months (P<.001) after surgery. There were no significant differences between gender, age, and type of operation. Body image and GSE improved significantly after bariatric surgery (P<.001), and both correlated to the SF-36 mental summary score. QOL, body image, and GSE improved significantly within 6 months and remained stable within 24 months after bariatric surgery. Improvements were independent of gender, age, and type of operation. Mental QOL was influenced by body image and GSE. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

Investigating the Relation between Women's Body Image and Unconsummated Marriage.

Unconsummated marriage is considered to be one of the complicated sexual issues that lead to multiple complications and problems for couples as well as the society. It is thought that this disorder is more common in traditional cultures and some religions such as Islam, Hinduism, and Judaism. The aim of this study was to determine the relation between women's body image and unconsummated marriage. This was a case-control study which was conducted among 50 women who had an unconsummated marriage (case group) and 100 women who had a consummated marriage (control group) in Isfahan, Iran during 2015-2016. Data were collected using the Multidimensional Body-Self Relations Questionnaire (MBSRQ). The data were analyzed using descriptive and inferential statistical tests. The total score of body image and all its components had no significant difference between both the groups of the case and the control ( P > 0.05). Considering that no relation was found between body image and unconsummated marriage and the religious culture of the Iranian society with conservative sexual norms, investigating unconsummated marriage with emphasis on cultural factors is recommended. Hence, such sexual disorders would be avoided and the number of affected people and challenges can be decreased.

Self-esteem mediates the relationship between connectedness to nature and body appreciation in women, but not men.

2016-03-01

Connectedness to nature (i.e., an affective and experiential connection to nature) is known to have a positive effect on psychological well-being, but its specific associations with body image have not been fully examined. To attend to this oversight, we conducted a preliminary investigation of associations between connectedness to nature and body appreciation. A total of 380 British adults completed measures of connectedness to nature, body appreciation, and self-esteem. Bivariate correlations revealed significant positive associations between all variables in women. In men, body appreciation was significantly correlated with self-esteem, but not connectedness to nature. Mediation analysis showed that, in women, self-esteem fully mediated the relationship between connectedness to nature and body appreciation. In men, body appreciation was significantly associated with self-esteem, but not connectedness to nature. These results point to a potential route for improving body image among women through connectedness to nature and self-esteem, but further research is necessary. Copyright © 2015 Elsevier Ltd.

Gambling, Tina S; Long, Andrew F

2013-03-01

To explore the experiences of young women with developmental dysplasia of the hip explicating the impact of peri-acetabular osteotomy surgery and recovery in the short and longer term. Postings of five, selected women on an online active message board aimed at women with developmental dysplasia of the hip were analysed. Interest lay on their postings after they had had peri-acetabular osteotomy surgery. Data analysis was performed through the approach of interpretive phenomenological analysis. The time length of the postings for the cases ranged from 1 year to 6 years, and the number of postings varied substantially, from 48 to 591. Two major concepts were prominent across participants' accounts. The first concept, 'body image', centred on affects on the women's self-esteem and body image. The second, 'the long road to recovery', highlighted 'the emotional and physical battle of learning to walk' and concerns with 'saving my joints'. Developmental dysplasia of the hip potentially provides a critical case for exploration of the process of how a disability can affect confidence, self-esteem and body image. Recovery from this condition requires enormous effort, resilience and commitment from the women.

Previous research has indicated that exposure to pro-eating disorder websites might increase eating pathology; however, the magnitude of this effect is unknown. This study aimed to conduct a systematic review and meta-analysis to examine the effect of exposure to pro-eating disorder websites on body image and eating pathology. Studies examining the relationship between exposure to pro-eating disorder websites and eating pathology-related outcomes were included. The systematic review identified nine studies. Findings revealed significant effect sizes of exposure to pro-eating disorder websites on body image dissatisfaction (five studies), d = .41, p = .003; dieting (six studies), d = .68, p < .001, and negative affect (three studies), d = 1.00, p < .001. No effect emerged for bulimic symptoms (four studies), d = .22, p = .73. Findings confirmed the effect of pro-eating disorder websites on body image and eating pathology, highlighting the need for enforceable regulation of these websites.

Mehta, Ushma J; Siega-Riz, Anna Maria; Herring, Amy H

2011-04-01

The majority of women gain more weight during pregnancy than what is recommended. Since gestational weight gain is related to short and long-term maternal health outcomes, it is important to identify women at greater risk of not adhering to guidelines. The objective of this study was to examine the relationship between body image and gestational weight gain. The Body Image Assessment for Obesity tool was used to measure ideal and current body sizes in 1,192 women participating in the Pregnancy, Infection and Nutrition Study. Descriptive and multivariable techniques were used to assess the effects of ideal body size and discrepancy score (current-ideal body sizes), which reflected the level of body dissatisfaction, on gestational weight gain. Women who preferred to be thinner had increased risk of excessive gain if they started the pregnancy at a BMI ≤26 kg/m(2) but a decreased risk if they were overweight or obese. Comparing those who preferred thin body silhouettes to those who preferred average size silhouettes, low income women had increased risk of inadequate weight gain [RR = 1.76 (1.08, 2.88)] while those with lower education were at risk of excessive gain [RR = 1.11 (1.00, 1.22)]. Our results revealed that body image was associated with gestational weight gain but the relationship is complex. Identifying factors that affect whether certain women are at greater risk of gaining outside of guidelines may improve our ability to decrease pregnancy-related health problems.

2014-01-01

This cross-sectional study of urban high schools in Johannesburg, South Africa, sought to examine eating attitudes, body image and self-esteem among male adolescents (n = 391). Anthropometric measurements, Eating Attitudes Test-26 (EAT-26), Rosenberg self-esteem, body image satisfaction and perception of females were collected at age 13, 15 and 17 years. Descriptive analysis was done to describe the sample, and non-parametric Wilcoxon Mann-Whitney test was used to test for significant differences between data that were not normally distributed (EAT-26). Spearman's rank correlation coefficient analyses were conducted to test for associations between self-esteem scores and eating attitudes, body mass indices and body image satisfaction scores. To assess the differences between groups that were normally distributed chi-square tests were carried out. Ethnic differences significantly affected adolescent boys' body mass index (BMI), eating attitudes and self-esteem; White boys had higher self-esteem, BMI and normal eating attitudes than the Black boys did. BMI was positively associated with self-esteem (p = 0.01, r = 0.134) and negatively with dieting behaviour in White boys (p = 0.004, r = -0.257), and with lower EAT-26 bulimic and oral control scores in Black boys. In conclusion, the findings highlight ethnic differences and a need to better understand cultural differences that influence adolescent attitudes and behaviour.

2014-01-01

Background: Massive weight loss (MWL) following bariatric surgery frequently results in an excess of overstretched skin causing physical discomfort and negatively affecting quality of life, self-esteem, body image, and physical functioning. Methods: In this cross-sectional study 3 groups were compared: (1) patients prior to bariatric surgery (n = 79), (2) patients after bariatric surgery who had not undergone body contouring surgery (BCS) (n = 252), and (3) patients after bariatric surgery who underwent subsequent BCS (n = 62). All participants completed self-report questionnaires assessing body image (Multidimensional Body-Self Relations Questionnaire, MBSRQ), quality of life (IWQOL-Lite), symptoms of depression (PHQ-9), and anxiety (GAD-7). Results: Overall, 62 patients (19.2%) reported having undergone a total of 90 BCS procedures. The most common were abdominoplasties (88.7%), thigh lifts (24.2%), and breast lifts (16.1%). Post-bariatric surgery patients differed significantly in most variables from pre-bariatric surgery patients. Although there were fewer differences between patients with and without BCS, patients after BCS reported better appearance evaluation (AE), body area satisfaction (BAS), and physical functioning, even after controlling for excess weight loss and time since surgery. No differences were found for symptoms of depression and anxiety, and most other quality of life and body image domains. Discussion: Our results support the results of longitudinal studies demonstrating significant improvements in different aspects of body image, quality of life, and general psychopathology after bariatric surgery. Also, we found better AE and physical functioning in patients after BCS following bariatric surgery compared to patients with MWL after bariatric surgery who did not undergo BCS. Overall, there appears to be an effect of BCS on certain aspects of body image and quality of life but not on psychological aspects on the whole. PMID:25477839

Weight-Bearing MR Imaging as an Option in the Study of Gravitational Effects on the Vocal Tract of Untrained Subjects in Singing Phonation

2014-01-01

Magnetic Resonance Imaging (MRI) of subjects in a supine position can be used to evaluate the configuration of the vocal tract during phonation. However, studies of speech phonation have shown that gravity can affect vocal tract shape and bias measurements. This is one of the reasons that MRI studies of singing phonation have used professionally trained singers as subjects, because they are generally considered to be less affected by the supine body position and environmental distractions. A study of untrained singers might not only contribute to the understanding of intuitive singing function and aid the evaluation of potential hazards for vocal health, but also provide insights into the effect of the supine position on singers in general. In the present study, an open configuration 0.25 T MRI system with a rotatable examination bed was used to study the effect of body position in 20 vocally untrained subjects. The subjects were asked to sing sustained tones in both supine and upright body positions on different pitches and in different register conditions. Morphometric measurements were taken from the acquired images of a sagittal slice depicting the vocal tract. The analysis concerning the vocal tract configuration in the two body positions revealed differences in 5 out of 10 measured articulatory parameters. In the upright position the jaw was less protruded, the uvula was elongated, the larynx more tilted and the tongue was positioned more to the front of the mouth than in the supine position. The findings presented are in agreement with several studies on gravitational effects in speech phonation, but contrast with the results of a previous study on professional singers of our group where only minor differences between upright and supine body posture were observed. The present study demonstrates that imaging of the vocal tract using weight-bearing MR imaging is a feasible tool for the study of sustained phonation in singing for vocally untrained subjects.

The paradoxical moderating effect of body image investment on the impact of weight-based derogatory media.

PubMed

Boersma, Katelyn E; Jarry, Josée L

2013-03-01

Weight-based derogatory media consist of derogation of celebrities for failing to meet the thin ideal. This study examined the impact of weight-based derogatory media on women's body satisfaction, appearance self-esteem, fear of negative appearance evaluation, and negative affect. Female undergraduates (N=240) were exposed to either tabloid-style pictures and articles derogating average size celebrities for gaining weight, or to the same images accompanied by neutral information. Women in the derogation condition reported greater fear of negative appearance evaluation than did women in the neutral media condition. Contrary to predictions, women low in maladaptive body image investment reported lower body satisfaction and appearance self-esteem in the derogatory media condition than they did in the neutral condition, while women high in maladaptive investment did not differ across conditions. Highly invested women's unexpected reaction may be understood as a defence against a threat to a valued domain of the self. Copyright © 2012 Elsevier Ltd. All rights reserved.

Young adult men (n=35) and women (n=57) completed open-ended questions identifying messages they had received from partners and the impact of these messages on their body image and sexual well-being. Content coding revealed three verbal (expressions of approval and pride, challenging negative beliefs, expressions of sexual attraction/arousal/desire) and two nonverbal (physical affection, physical expressions of sexual attraction/arousal/desire) positive messages as well as one verbal (disapproval/disgust) and two nonverbal (rejection, humiliation) negative messages. Some participants reported gender-related messages (muscularity/strength, genital appearance, breast appearance, weight, and comparison to others). Positive messages were seen to increase confidence, self-acceptance, and sexual empowerment/fulfillment, whereas negative messages decreased these feelings. Our findings suggest that even everyday, seemingly neutral messages are perceived to have an important impact on young adults. Copyright © 2016 Elsevier Ltd. All rights reserved.

We conducted an empirical study to clarify how psychosocial factors (e.g. body image and sexuality) influence therapeutic decision-making and to identify the factors that affect post-operative mood states in Japanese women who underwent various types of surgery. One hundred and two patients who had undergone surgical treatment for breast cancer participated in this study. Twenty-five patients had undergone mastectomy, 67 breast conserving treatment and 11 skin-sparing mastectomy and immediate breast reconstruction. The participants were evaluated based on a battery of questionnaires including value estimates of decision-making factors, a shortened version of the Profile of Mood States and self-efficacy. The patients regarded the possibility of cure and recurrence of cancer as well as the physician's support as important, regardless of the treatments they had chosen. The patients that had immediate breast reconstruction placed significantly more importance on their body image and sexuality (i.e. physical appearance, attractiveness to partner and self-evaluation of femininity and sexuality) than the mastectomy patients. After surgery, the former group tended to have a more negative mood on the shortened version of the Profile of Mood States than the latter group. Degree of self-efficacy had a marked influence on the patients' mood after surgery. This study suggests the importance of discussing body image and sexuality that has tended to be disregarded in therapeutic decision-making situations in breast cancer patients in Japan. Self-efficacy is a crucial variable for improving mood after treatment.

PET is widely considered the most sensitive technique available for noninvasively studying physiology, metabolism, and molecular pathways in the living human being. However, the utility of PET, being a photon-deficient modality, remains constrained by factors including low signal-to-noise ratio, long imaging times, and concerns about radiation dose. Two developments offer the potential to dramatically increase the effective sensitivity of PET. First by increasing the geometric coverage to encompass the entire body, sensitivity can be increased by a factor of about 40 for total-body imaging or a factor of about 4-5 for imaging a single organ such as the brain or heart. The world's first total-body PET/CT scanner is currently under construction to demonstrate how this step change in sensitivity affects the way PET is used both in clinical research and in patient care. Second, there is the future prospect of significant improvements in timing resolution that could lead to further effective sensitivity gains. When combined with total-body PET, this could produce overall sensitivity gains of more than 2 orders of magnitude compared with existing state-of-the-art systems. In this article, we discuss the benefits of increasing body coverage, describe our efforts to develop a first-generation total-body PET/CT scanner, discuss selected application areas for total-body PET, and project the impact of further improvements in time-of-flight PET. © 2018 by the Society of Nuclear Medicine and Molecular Imaging.

Theory review and interaction design space of body image and body schema (BIBS) for embodied cognition in virtual reality

NASA Astrophysics Data System (ADS)

2015-03-01

Body image/body schema (BIBS) is within the larger realm of embodied cognition. Its interdisciplinary literature can inspire Virtual Reality (VR) researchers and designers to develop novel ideas and provide them with approaches to human perception and experience. In this paper, we introduced six fundamental ideas in designing interactions in VR, derived from BIBS literature that demonstrates how the mind is embodied. We discuss our own research, ranging from two mature works to a prototype, to support explorations VR interaction design from a BIBS approach. Based on our experiences, we argue that incorporating ideas of embodiment into design practices requires a shift in the perspective or understanding of the human body, perception and experiences, all of which affect interaction design in unique ways. The dynamic, interactive and distributed understanding of cognition guides our approach to interaction design, where the interrelatedness and plasticity of BIBS play a crucial role.

Closed circuit television (CCTV) systems are being widely used in crime surveillance. The images produced are of poor quality often face details are not visible, however expert witnesses in the field of biological anthropology use morphological descriptions of body shapes in an attempt to identify persons of interest. These methods can be applied to individual images when other cues such as gait, are not present. Criminals commonly disguise their faces, but body shape characteristics can be used to distinguish a person of interest from others. Garments may distort the body shape appearance, thus this study was undertaken to investigate the effects of garments on the description of body shape from CCTV images. Twelve adult males representing a wide body shape range of Sheldonian somatotypes were photographed in identical garments comprising of tight fitting black shirt, horizontally striped shirt, padded leather jacket and in naked torso. These photographs were assessed by 51 males and females aged 18-50 years, with varying levels of education, and different experience in use of CCTV images for identification of people, to identify the 12 participants. The effect of assessors was not significant. They correctly distinguished 88.6% of individuals wearing the same wear, but could not match the same individuals wearing different wear above the random expectations. However, they matched somatotypes above random expectation. Type of clothing produced little bias in somatotype matching; ectomorphic component of individuals wearing black shirts and padded jackets was overestimated and underestimated, respectively. In conclusion, type of the wear had little effect in the description of individuals from CCTV images using the body shapes.

The purpose of this study was to examine the effects of including female athletes' weights in athletic event programs on female spectators' body image, eating disorder symptoms, self-esteem, and affective state and to investigate whether the magnitude of the athletes' reported weights had differential effects on female spectators (i.e., do female spectators who view heavier athletes respond differently than those who view less heavy athletes?). We used an experimental design to examine hypotheses derived from competing theories to determine whether exposure to female athletes of varying weight would adversely or beneficially impact female undergraduates (N = 152) who served as athletic event spectators. Analyses indicated that in this simulated study, female spectators' body image, eating disorder symptoms, self-esteem, and affective states were not impacted by the presence or by the magnitude of female athletes' weights in athletic event programs. The results imply that including athletes' weights in game-day programs at women's athletic events does not affect female spectators on an individual level.

Effects of affective picture viewing on postural control.

PubMed

Stins, John F; Beek, Peter J

2007-10-04

Emotion theory holds that unpleasant events prime withdrawal actions, whereas pleasant events prime approach actions. Recent studies have suggested that passive viewing of emotion eliciting images results in postural adjustments, which become manifest as changes in body center of pressure (COP) trajectories. From those studies it appears that posture is modulated most when viewing pictures with negative valence. The present experiment was conducted to test the hypothesis that pictures with negative valence have a greater impact on postural control than neutral or positive ones. Thirty-four healthy subjects passively viewed a series of emotion eliciting images, while standing either in a bipedal or unipedal stance on a force plate. The images were adopted from the International Affective Picture System (IAPS). We analysed mean and variability of the COP and the length of the associated sway path as a function of emotion. The mean position of the COP was unaffected by emotion, but unipedal stance resulted in overall greater body sway than bipedal stance. We found a modest effect of emotion on COP: viewing pictures of mutilation resulted in a smaller sway path, but only in unipedal stance. We obtained valence and arousal ratings of the images with an independent sample of viewers. These subjects rated the unpleasant images as significantly less pleasant than neutral images, and the pleasant images as significantly more pleasant than neutral images. However, the subjects rated the images as overall less pleasant and less arousing than viewers in a closely comparable American study, pointing to unknown differences in viewer characteristics. Overall, viewing emotion eliciting images had little effect on body sway. Our finding of a reduction in sway path length when viewing pictures of mutilation was indicative of a freezing strategy, i.e. fear bradycardia. The results are consistent with current knowledge about the neuroanatomical organization of the emotion system and the neural control of behavior.

2017-03-01

Body exposure is a common and effective treatment for body image disturbance in bulimia nervosa (BN). However, little is known about treatment mechanisms. Based on models of emotional processing and neurovisceral integration, we expected to observe a) initial activation and b) habituation of cognitive-affective and autonomic responding within one and between two standardized body exposure sessions. A group of 13 women with BN and 13 healthy controls (HC) were repeatedly exposed to their bodies. Prior to and after treatment with three individualized mirror exposure sessions participants received a session of standardized exposure to videographic recordings of their body. Subjective ratings of body-related emotions and thoughts were assessed repeatedly throughout the standardized exposure sessions and autonomic responses were recorded continuously. Subjective and sympathetic responses were activated initially in both groups. Cognitive-affective responses habituated within the standardized sessions in both groups, whereas between the standardized sessions habituation was only found in women with BN. Increasing sympathetic responses were found within the sessions in both groups. The results support cognitive-affective habituation during body exposure in BN and to a lesser extent in HC. Autonomic responses however did not show a corresponding pattern and did not distinguish between groups. Implications for body exposure research and practice are discussed.

Spinal infections represent a group of rare conditions affecting vertebral bodies, intervertebral discs, paraspinal soft tissues, epidural space, meninges, and spinal cord. The causal factors, clinical presentations, and imaging features are a challenge because the difficulty to differentiate them from other conditions, such as degenerative and inflammatory disorders and spinal neoplasm. They require early recognition because delay diagnosis, imaging, and intervention may have devastating consequences especially in children and the elderly. This article reviews the most common spinal infections, their pathophysiologic, clinical manifestation, and their imaging findings.

What factors mediate the relationship between global self-worth and weight and shape concerns?

Murphy, Edel; Dooley, Barbara; Menton, Aoife; Dolphin, Louise

2016-04-01

The primary aim of this study was to investigate whether the relationship between global self-worth and weight concerns and global self-worth and shape concerns was mediated by pertinent body image factors, while controlling for gender and estimated BMI. Participants were 775 adolescents (56% male) aged 12-18years (M=14.6; SD=1.50). Mediation analysis revealed a direct and a mediated effect between global self-worth and two body image models: 1) weight concerns and 2) shape concerns. The strongest mediators in both models were physical appearance, restrained eating, and depression. Partial mediation was observed for both models, indicating that body image factors which span cognitive, affective, and behavioral constructs, explain the association between global self-worth and weight and shape concerns. Implications for future research, weight and shape concern prevention and global self-worth enhancement programs are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Body awareness, eating attitudes, and spiritual beliefs of women practicing yoga.

2009-01-01

This research evaluated attitudes about body image and eating in women practicing postural yoga. Study 1 described scores from questionnaires on variables related to body awareness, intuitive eating, spirituality, and reasons for practicing. Scores were favorable on all measures with significant correlations (p < .01) among all main variables except between spiritual readiness and intuitive eating, and between BMI and both body awareness and spiritual readiness. Reasons for practicing did not affect scores. Study 2 evaluated interviews in a sub-sample. Qualitative data reported improvements in body satisfaction and disordered eating due in part to yoga and its associated spirituality.

Investigating the Relation between Women's Body Image and Unconsummated Marriage

Background: Unconsummated marriage is considered to be one of the complicated sexual issues that lead to multiple complications and problems for couples as well as the society. It is thought that this disorder is more common in traditional cultures and some religions such as Islam, Hinduism, and Judaism. The aim of this study was to determine the relation between women's body image and unconsummated marriage. Materials and Methods: This was a case-control study which was conducted among 50 women who had an unconsummated marriage (case group) and 100 women who had a consummated marriage (control group) in Isfahan, Iran during 2015–2016. Data were collected using the Multidimensional Body-Self Relations Questionnaire (MBSRQ). The data were analyzed using descriptive and inferential statistical tests. Results: The total score of body image and all its components had no significant difference between both the groups of the case and the control (P > 0.05). Conclusions: Considering that no relation was found between body image and unconsummated marriage and the religious culture of the Iranian society with conservative sexual norms, investigating unconsummated marriage with emphasis on cultural factors is recommended. Hence, such sexual disorders would be avoided and the number of affected people and challenges can be decreased. PMID:29033990

Interoceptive signals impact visual processing: Cardiac modulation of visual body perception.

2017-09-01

Multisensory perception research has largely focused on exteroceptive signals, but recent evidence has revealed the integration of interoceptive signals with exteroceptive information. Such research revealed that heartbeat signals affect sensory (e.g., visual) processing: however, it is unknown how they impact the perception of body images. Here we linked our participants' heartbeat to visual stimuli and investigated the spatio-temporal brain dynamics of cardio-visual stimulation on the processing of human body images. We recorded visual evoked potentials with 64-channel electroencephalography while showing a body or a scrambled-body (control) that appeared at the frequency of the on-line recorded participants' heartbeat or not (not-synchronous, control). Extending earlier studies, we found a body-independent effect, with cardiac signals enhancing visual processing during two time periods (77-130 ms and 145-246 ms). Within the second (later) time-window we detected a second effect characterised by enhanced activity in parietal, temporo-occipital, inferior frontal, and right basal ganglia-insula regions, but only when non-scrambled body images were flashed synchronously with the heartbeat (208-224 ms). In conclusion, our results highlight the role of interoceptive information for the visual processing of human body pictures within a network integrating cardio-visual signals of relevance for perceptual and cognitive aspects of visual body processing.

2018-03-01

The strain errors in stereo-digital image correlation (DIC) due to camera calibration were investigated using precisely controlled numerical experiments and real experiments. Three-dimensional rigid body motion tests were conducted to examine the effects of camera calibration on the measured results. For a fully accurate calibration, rigid body motion causes negligible strain errors. However, for inaccurately calibrated camera parameters and a short working distance, rigid body motion will lead to more than 50-μɛ strain errors, which significantly affects the measurement. In practical measurements, it is impossible to obtain a fully accurate calibration; therefore, considerable attention should be focused on attempting to avoid these types of errors, especially for high-accuracy strain measurements. It is necessary to avoid large rigid body motions in both two-dimensional DIC and stereo-DIC.

Investment in body image for self-definition results in greater vulnerability to the thin media than does investment in appearance management.

PubMed

Ip, Karen; Jarry, Josée L

2008-03-01

This study investigated the effect of thin images according to two dimensions of body-image (BI) investment. Ninety-five females were classified as high or low investors based on the Appearance Schemas Inventory-Revised Self-Evaluative Salience (SES) and Motivational Salience (MS) subscales. Participants viewed advertisements portraying either the thin ideal or products. Results indicated that both women high in SES and MS reported lowered appearance self-esteem but greater BI importance following thin exposures. However, only the high SES group reported greater BI dissatisfaction and importance of current-ideal discrepancies after seeing thin images. Although highly invested women (regardless of their motivation for investment) are more responsive to thin media images than are women low in investment, those invested for self-definition are affected on more dimensions than are those invested for appearance management.

Sexual orientation and shifts in preferences for a partner's body attributes in short-term versus long-term mating contexts.

2011-06-01

This study assessed the effects of short- and long-term mating contexts on preferences for body characteristics of potential relationship partners in lesbians and heterosexual women. Lesbians (n = 41) rated figure drawings and computer-generated images of women that varied in body fat, waist-to-hip ratio, and breast size; heterosexual women (n = 95) rated computer-generated images of men that varied in muscularity and body fat. Both lesbians and heterosexual women showed a shift in preferences toward more physically attractive partners for shortterm relationships. All body aspects were affected, except that heterosexual women did not show a preference shift for male body fat. The results were interpreted in terms of a mating trade-off strategy in which mate preferences are the consequence of cost/benefit analyses and suggest that preferences for physical attributes of sexual partners may be shared by members of the same sex regardless of sexual orientation.

Influence of fears of compassion on body image shame and disordered eating.

Dias, Bernardo Santos; Ferreira, Cláudia; Trindade, Inês A

2018-06-07

The current study tested a path model examining the impact of fears of compassion in the adoption of disordered eating and whether social safeness and body shame would mediate this relationship. Participants were 645 women (aged between 18 and 55) from the general community, who completed an online survey. Results indicated that fears of compassion were negatively associated with one's ability to feel secure and safe within close relationships, and positively linked with higher levels of body shame and disordered eating. The tested model accounted for 62% of the variance of disordered eating. Path analyses results revealed that the three dimensions of fears of compassion impacted on disordered eating. Particularly, fear of expressing compassion for others presented a direct impact on disordered eating. Moreover, fears of self-compassion and fears of receiving compassion from others partially impacted on disordered eating attitudes and behaviours, through the mechanisms of social safeness and body image-focused shame. These findings suggested that women who present higher levels of fear of self-compassion and of receiving signs of affection and compassion from others tend to feel more insecure in their social group, which seem explain body shame and the engagement in disordered eating behaviours. This study highlights the pathogenic impact of fears of compassion on body image and eating attitudes and behaviours. The current data seem to offer relevant insights for research and clinical practice, by supporting the relevance of developing compassionate abilities and attitudes to target body image and eating-related difficulties.

Depression is linked with alexithymia, anxiety, high HbA1c concentrations, disturbances of cortisol secretion, increased prevalence of diabetes complications and all-cause mortality. The psycho-educational method 'affect school with script analysis' and the mind-body therapy 'basic body awareness treatment' will be trialled in patients with diabetes, high HbA1c concentrations and psychological symptoms. The primary outcome measure is change in symptoms of depression. Secondary outcome measures are changes in HbA1c concentrations, midnight salivary cortisol concentration, symptoms of alexithymia, anxiety, self-image measures, use of antidepressants, incidence of diabetes complications and mortality. Two studies will be performed. Study I is an open-labeled parallel-group study with a two-arm randomized controlled trial design. Patients are randomized to either affect school with script analysis or to basic body awareness treatment. According to power calculations, 64 persons are required in each intervention arm at the last follow-up session. Patients with type 1 or type 2 diabetes were recruited from one hospital diabetes outpatient clinic in 2009. The trial will be completed in 2016. Study II is a multicentre open-labeled parallel-group three-arm randomized controlled trial. Patients will be randomized to affect school with script analysis, to basic body awareness treatment, or to treatment as usual. Power calculations show that 70 persons are required in each arm at the last follow-up session. Patients with type 2 diabetes will be recruited from primary care. This study will start in 2016 and finish in 2023. For both studies, the inclusion criteria are: HbA1c concentration ≥62.5 mmol/mol; depression, alexithymia, anxiety or a negative self-image; age 18-59 years; and diabetes duration ≥1 year. The exclusion criteria are pregnancy, severe comorbidities, cognitive deficiencies or inadequate Swedish. Depression, anxiety, alexithymia and self-image are assessed using self-report instruments. HbA1c concentration, midnight salivary cortisol concentration, blood pressure, serum lipid concentrations and anthropometrics are measured. Data are collected from computerized medical records and the Swedish national diabetes and causes of death registers. Whether the "affect school with script analysis" will reduce psychological symptoms, increase emotional awareness and improve diabetes related factors will be tried, and compared to "basic body awareness treatment" and treatment as usual.

When Closure Fails: What the Radiologist Needs to Know About the Embryology, Anatomy, and Prenatal Imaging of Ventral Body Wall Defects.

Torres, Ulysses S; Portela-Oliveira, Eduardo; Braga, Fernanda Del Campo Braojos; Werner, Heron; Daltro, Pedro Augusto Nascimento; Souza, Antônio Soares

2015-12-01

Ventral body wall defects (VBWDs) are one of the main categories of human congenital malformations, representing a wide and heterogeneous group of defects sharing a common feature, that is, herniation of one or more viscera through a defect in the anterior body wall. Gastroschisis and omphalocele are the 2 most common congenital VBWDs. Other uncommon anomalies include ectopia cordis and pentalogy of Cantrell, limb-body wall complex, and bladder and cloacal exstrophy. Although VBWDs are associated with multiple abnormalities with distinct embryological origins and that may affect virtually any system organs, at least in relation to anterior body wall defects, they are thought (except for omphalocele) to share a common embryologic mechanism, that is, a failure involving the lateral body wall folds responsible for closing the thoracic, abdominal, and pelvic portions of the ventral body wall during the fourth week of development. Additionally, many of the principles of diagnosis and management are similar for these conditions. Fetal ultrasound (US) in prenatal care allows the diagnosis of most of such defects with subsequent opportunities for parental counseling and optimal perinatal management. Fetal magnetic resonance imaging may be an adjunct to US, providing global and detailed anatomical information, assessing the extent of defects, and also helping to confirm the diagnosis in equivocal cases. Prenatal imaging features of VBWDs may be complex and challenging, often requiring from the radiologist a high level of suspicion and familiarity with the imaging patterns. Because an appropriate management is dependent on an accurate diagnosis and assessment of defects, radiologists should be able to recognize and distinguish between the different VBWDs and their associated anomalies. In this article, we review the relevant embryology of VBWDs to facilitate understanding of the pathologic anatomy and diagnostic imaging approach. Features will be illustrated with prenatal US and magnetic resonance imaging and correlated with postnatal and clinical imaging. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim was to determine the influence of patient age, gender, body mass index (BMI), amount of dental restorations, and implants on image quality of cone-beam computerized tomography (CBCT). Fifty CBCT scans of a preretail version of Galileos (Sirona, Germany) were investigated retrospectively by 4 observers regarding image quality of 6 anatomic structures, pathologic findings detection, subjective exposure quality, and artifacts. Patient age, BMI, gender, amount of dental restorations, and implants were recorded and statistically tested for correlations to image quality. A negative effect on image quality was found statistically significantly correlated with age and the amount of dental restorations. None of the investigated image features were garbled by any of the investigated influence factors. Age and the amount of dental restorations appear to have a negative impact on CBCT image quality, whereas gender and BMI do not. Image quality of mental foramen, mandibular canal, and nasal floor are affected negatively by age but not by the amount of dental restorations. Further studies are required to elucidate influence factors on CBCT image quality.

Judging the difference between attractiveness and health: does exposure to model images influence the judgments made by men and women?

PubMed

Stephen, Ian D; Perera, A Treshi-Marie

2014-01-01

Recent research has shown facial adiposity (apparent weight in the face) to be a significant predictor of both attractiveness and health, thus making it an important determinant of mate selection. Studies looking at the relationship between attractiveness and health have shown that individuals differentiate between the two by preferring a lower weight for attractiveness than for health in female faces. However, these studies have either been correlational studies, or have investigated weight perceived from only the face. These differences have been discussed with regard to sociocultural factors such as pressure from parents, peers and also media, which has been seen to have the highest influence. While exposure to media images has been shown to influence women's own-body image, no study has yet directly tested the influence of these factors on people's preferred weight in other women's bodies. Here we examine how a short exposure to images of models influences men's and women's judgments of the most healthy looking and attractive BMI in Malaysian Chinese women's bodies by comparing differences in preferences (for attractiveness and health) between groups exposed to images of models of varying attractiveness and body weight. Results indicated that participants preferred a lower weight for attractiveness than for health. Further, women's but not men's preferred BMI for attractiveness, but not health, was influenced by the type of media images to which they were exposed, suggesting that short term exposure to model images affect women's perceptions of attractiveness but not health.

What we see when we digitize pain: The risk of valorizing image-based representations of fibromyalgia over body and bodily experience

PubMed Central

Manivannan, Vyshali

2017-01-01

Fibromyalgia is chronic pain of unknown etiology, attended by fatigue and affective dysfunction. Unapparent to the unpracticed eye or diagnostic image, it is denied the status of “real” suffering given to visually confirmable disorders. It is my customary mode of existence: a contingent landscape of swinging bridges that may or may not give way, everything a potential threat or deprivation. I don’t express it within the framework of acute pain, but I am evaluated by traditional biomedical standards anyway. Ultimately, the diagnostic image of pain, and the medical and academic discourse used to interpret it, determines my functionality. Such a stance dismisses bodily senses and alternate ways of knowing in pursuit of the ocularcentric objectivity promised by digital health technologies, whose vision remains chained to the interpretive, discursive strategies of human operators and interpreters. A new poetics of pain is critical not only for rewriting the dominant metaphors that construct and delimit our imaginings of pain but also for rewiring the use and reading of digital technologies, wherein the digital image becomes the new site of the hermeneutic exercise, even when the suffering body lies in plain view. This facilitates a failure to listen and touch in patient care, and the imposition of a narrative based on visual evidence, translated into sanitized language, at the cost of intercorporeality. If pain strips sufferers of a voice, my body and its affects should be allowed to speak. PMID:29942598

Social relations and breath odour.

PubMed

McKeown, L

2003-11-01

In this retrospective qualitative study, the researcher reviewed 55 client records of The Breath Odour Clinic. The purpose was to determine if individuals attended a clinic specialised in treating oral malodour for medical or social reasons. The study focused on the psychosocial and breath odour history. Clients had agreed to the use of information for research purposes. Society uses odour as a means to define and interact with the world. The olfactory, smelling experience is intimate, emotionally charged and connects us with the world. It follows that the smell from mouth breath odour can connect or disconnect a person from their social environment and intimate relationships. How one experiences one's own body is very personal and private but also very public. Breath odour is public as it occurs within a social and cultural context and personal as it affects one's body image and self-confidence. Body image, self-image and social relations mesh, interact and impact upon each other. Breath odour is a dynamic and interactive aspect of the self-image. In addition, breath odour may be value-coded as 'bad'. In 75% of the cases reviewed, decreased self-confidence and insecurity in social and intimate relations led clients to seek treatment at the specialised breath odour clinic. Their doctor, dental hygienist or dentist had treated medical and oral conditions but not resolved their breath odour problem. When a person perceives a constant bad breath problem, she/he uses defence techniques, and may avoid social situations and social relations. This affects a person's well-being.

The brain integrates multiple sensory inputs, including somatosensory and visual inputs, to produce a representation of the body. Spinal cord injury (SCI) interrupts the communication between brain and body and the effects of this deafferentation on body representation are poorly understood. We investigated whether the relative weight of somatosensory and visual frames of reference for body representation is altered in individuals with incomplete or complete SCI (affecting lower limbs’ somatosensation), with respect to controls. To study the influence of afferent somatosensory information on body representation, participants verbally judged the laterality of rotated images of feet, hands, and whole-bodies (mental rotation task) in two different postures (participants’ body parts were hidden from view). We found that (i) complete SCI disrupts the influence of postural changes on the representation of the deafferented body parts (feet, but not hands) and (ii) regardless of posture, whole-body representation progressively deteriorates proportionally to SCI completeness. These results demonstrate that the cortical representation of the body is dynamic, responsive, and adaptable to contingent conditions, in that the role of somatosensation is altered and partially compensated with a change in the relative weight of somatosensory versus visual bodily representations.

This investigation uncovered processes underlying the dynamics of body weight and body image among individuals involved in nascent heterosexual marital relationships in Upstate New York. In-depth, semi-structured qualitative interviews conducted with 34 informants, 20 women and 14 men, just prior to marriage and again one year later were used to explore continuity and change in cognitive, affective, and behavioral factors relating to body weight and body image at the time of marriage, an important transition in the life course. Three major conceptual themes operated in the process of developing and enacting informants’ body weight relationships with their partner: weight relevance, weight comparisons, and weight talk. Weight relevance encompassed the changing significance of weight during early marriage and included attracting and capturing a mate, relaxing about weight, living healthily, and concentrating on weight. Weight comparisons between partners involved weight relativism, weight competition, weight envy, and weight role models. Weight talk employed pragmatic talk, active and passive reassurance, and complaining and critiquing criticism. Concepts emerging from this investigation may be useful in designing future studies of and approaches to managing body weight in adulthood. PMID:21864601

The objective of this study was to evaluate the clinical usefulness of whole-body magnetic resonance imaging (MRI) in facio-scapulo-humeral muscular dystrophy (FSHD). In 20 patients with genetically proven FSHD1, we prospectively assessed muscular involvement and correlated the results of semi-quantitative manual muscle testing and other parameters such as disease duration, creatine kinase (CK) levels and repeat length of the D4Z4 locus with whole-body MRI. Clinical muscle testing revealed the trapezius, pectoralis and infraspinatus as the most severely affected muscles in the shoulder, and the knee flexors and gluteus medius in the hip girdle. MRI revealed the trapezius and serratus anterior muscles in the shoulder, and the hamstrings and adductor muscles in the hip girdle, as the most severely affected muscle groups. Overall, degrees of fatty degeneration on MRI scans correlated significantly with clinical weakness. Moreover, we could detect clear affection of the trunk muscles. Corresponding to earlier reports, asymmetric involvement was frequent in both clinical examination and MRI scoring. Moreover, MRI revealed inhomogeneous muscle degeneration in a considerable proportion of both, muscles and patients. Both clinical and MRI scores significantly correlated to disease duration, but not to fragment size or CK levels. Fatty degeneration in whole-body MRI correlates well to clinical muscle testing of the extremities but gives more information on deeper or trunk muscles. It shows structural changes in muscular disorders and may become an excellent tool for assessment of muscle involvement and follow-up studies.

To examine the effects of age, body image, and risk framing on treatment decision making for breast cancer using a healthy population. An experimental 2 (younger women, older women) X 2 (survival, mortality frame) between-groups design. Midwestern university. Two groups of healthy women: 56 women ages 18-24 from undergraduate psychology courses and 60 women ages 35-60 from the university community. Healthy women imagined that they had been diagnosed with breast cancer and received information regarding lumpectomy versus mastectomy and recurrence rates. Participants indicated whether they would choose lumpectomy or mastectomy and why. Age, framing condition, treatment choice, body image, and reasons for treatment decision. The difference in treatment selection between younger and older women was mediated by concern for appearance. No main effect for risk framing was found; however, older women were somewhat less likely to select lumpectomy when given a mortality frame. Age, mediated by body image, influences treatment selection of lumpectomy versus mastectomy. Framing has no direct effect on treatment decisions, but younger and older women may be affected by risk information differently. Nurses should provide women who recently have been diagnosed with breast cancer with age-appropriate information regarding treatment alternatives to ensure women's active participation in the decision-making process. Women who have different levels of investment in body image also may have different concerns about treatment, and healthcare professionals should be alert to and empathetic of such concerns.

Open surface water bodies are important water resource for public supply, irrigation, livestock, and wildlife in Oklahoma. The inter-annual variation of Oklahoma water bodies directly affect the water availability for public supply, irrigation and cattle industry. In this study, tens of thousands of Landsat TM/ETM+ images from 1984 to 2015 were used to track the dynamics of open surface water bodies. Both water-related spectral indices and vegetation indices were used to map water bodies for individual images. The resultant maps show that Oklahoma year-long open surface water bodies varied significantly over the last 32 years, with an average annual water body area equals to 2300 km2, accounting for 1.27 % of the Oklahoma state area (181,037 km2). 4.3 million year-long water body pixels were detected in the 32-year accumulated water frequency map, corresponding to 3100 km2. Only 45% ( 1400 km2) of the those pixels had water throughout the 32 years, while the rest 55% pixels had a dry-up period. The smaller water bodies have a higher risk to dry up and a lower probability to have water throughout the years. Drought years could significantly decrease the number of small water bodies and shrink the area of large water bodies, while pluvial years could create large number of small seasonal water bodies. The significant influencing factors of current year water bodies include the precipitation and temperature of current year and the water body condition of the previous year. This water body dynamics study could be used to support water resource management, crop and livestock production, and biodiversity conservation in Oklahoma.

According to the World Health Organization definition, sexual health is more than mere physical sexual function; it also encompasses emotional, mental, and social well-being in relation to sexuality and is not merely the absence of dysfunction or disease. In line with this definition, various studies have reported that female sexual function is associated with partnership quality, body image, and body self-acceptance. To investigate whether female sexual function is influenced by (i) body self-acceptance and (ii) partnership quality, as important factors in psychosocial well-being, and (iii) whether the effects of body self-acceptance are moderated by partnership quality. In total, 2,685 female medical students no older than 35 years from Germany, Austria, and Switzerland completed an anonymous online questionnaire comprising the Female Sexual Function Index (FSFI) and the Self-Acceptance of the Body Scale. Respondents were asked to state whether they had been in a steady partnership in the preceding 6 months. When present, the quality of the partnership status was rated (enamoredness, love, friendship, or conflicted). To determine correlations, group differences, and moderating effects among body self-acceptance, partnership quality, and sexual function, the data were analyzed using Spearman correlations, Kruskal-Wallis tests, and analyses of variance. Female sexual function (FSFI total score). (i) In sexually active women, higher FSFI scores were significantly associated with greater body self-acceptance and a steady partnership during the preceding 6 months. (ii) Total FSFI scores were highest in women who described their partnership as enamored (29.45) or loving (28.55). Lower scores were observed in single women (26.71) and in women who described their partnerships as friendship (25.76) or as emotionally conflicted (23.41). (iii) Total FSFI score was affected by an interaction between body self-acceptance and partnership quality. Body self- acceptance was positively associated with FSFI total scores, particularly in single women and women in emotionally conflicted partnerships. Our findings suggest that in young women, body self-acceptance and partnership quality are positively associated with better sexual function, and that high body self-acceptance might buffer the negative impact on sexual function of partnership quality. The present data suggest that psychological interventions to improve the body image of younger women can positively affect sexual function and thereby improve sexual health.

Visceral Leishmaniasis is a parasitic disease that affects liver, spleen and bone marrow. According to World Health Organization report, definitive diagnosis is possible just by direct observation of the Leishman body in the microscopic image taken from bone marrow samples. We utilize morphological and CV level set method to segment Leishman bodies in digital color microscopic images captured from bone marrow samples. Linear contrast stretching method is used for image enhancement and morphological method is applied to determine the parasite regions and wipe up unwanted objects. Modified global and local CV level set methods are proposed for segmentation and a shape based stopping factor is used to hasten the algorithm. Manual segmentation is considered as ground truth to evaluate the proposed method. This method is tested on 28 samples and achieved 10.90% mean of segmentation error for global model and 9.76% for local model.

Changes in body image and subjective well-being variables (e.g. self-esteem) are often reported as outcomes of obesity treatment. However, they may, in turn, also influence behavioral adherence and success in weight loss. The present study examined associations among obesity treatment-related variables, i.e., change in weight, quality of life, body image, and subjective well-being, exploring their role as both mediators and outcomes, during a behavioral obesity treatment. Participants (BMI = 31.1 +/- 4.1 kg/m2; age = 38.4 +/- 6.7 y) were 144 women who attended a 12-month obesity treatment program and a comparison group (n = 49), who received a general health education program. The intervention included regular group meetings promoting lasting behavior changes in physical activity and dietary intake. Body image, quality of life, subjective well-being, and body weight were measured at baseline and treatment's end. Mediation was tested by multiple regression and a resampling approach to measure indirect effects. Treatment group assignment was the independent variable while changes in weight and in psychosocial variables were analyzed alternatively as mediators and as dependent variables. At 12 months, the intervention group had greater weight loss (-5.6 +/- 6.8% vs. -1.2 +/- 4.6%, p < .001) and larger decreases in body size dissatisfaction (effect size of 1.08 vs. .41, p < .001) than the comparison group. Significant improvements were observed in both groups for all other psychosocial variables (effect sizes ranging from .31-.75, p < .05). Mediation analysis showed that changes in body image and body weight were concurrently mediators and outcomes of treatment, suggesting reciprocal influences. Weight loss partially mediated the effect of treatment on quality of life and on self-esteem but the reciprocal effect was not observed. Changes in weight and body image may reciprocally affect each other during the course of behavioral obesity treatment. No evidence of reciprocal relationships was found for the other models under analysis; however, weight changes partially explained the effects of treatment on quality of life and self-esteem. Weight and psychosocial changes co-occur during treatment and will probably influence each other dynamically, in ways not yet adequately understood. Results from this study support the inclusion of intervention contents aimed at improving body image in weight management programs.

Unwanted contrast in high resolution satellite images such as shadow areas directly affects the result of further processing in urban remote sensing images. Detecting and finding the precise position of shadows is critical in different remote sensing processing chains such as change detection, image classification and digital elevation model generation from stereo images. The spectral similarity between shadow areas, water bodies, and some dark asphalt roads makes the development of robust shadow detection algorithms challenging. In addition, most of the existing methods work on pixel-level and neglect the contextual information contained in neighboring pixels. In this paper, a new object-based shadow detection framework is introduced. In the proposed method a pixel-level shadow mask is built by extending established thresholding methods with a new C4 index which enables to solve the ambiguity of shadow and water bodies. Then the pixel-based results are further processed in an object-based majority analysis to detect the final shadow objects. Four different high resolution satellite images are used to validate this new approach. The result shows the superiority of the proposed method over some state-of-the-art shadow detection method with an average of 96% in F-measure.

Female genital mutilation (FGM), the partial or total removal of the external genitalia for non-medical reasons, can affect female sexuality. However, only few studies are available, and these have significant methodologic limitations. To understand the impact of FGM on the anatomy of the clitoris and bulbs using magnetic resonance imaging and on sexuality using psychometric instruments and to study whether differences in anatomy after FGM correlate with differences in sexual function, desire, and body image. A cross-sectional study on sexual function and sexual anatomy was performed in women with and without FGM. Fifteen women with FGM involving cutting of the clitoris and 15 uncut women as a control group matched by age and parity were prospectively recruited. Participants underwent pelvic magnetic resonance imaging with vaginal opacification by ultrasound gel and completed validated questionnaires on desire (Sexual Desire Inventory), body image (Questionnaire d'Image Corporelle [Body Image Satisfaction Scale]), and sexual function (Female Sexual Function Index). Primary outcomes were clitoral and bulbar measurements on magnetic resonance images. Secondary outcomes were sexual function, desire, and body image scores. Women with FGM did not have significantly decreased clitoral glans width and body length but did have significantly smaller volume of the clitoris plus bulbs. They scored significantly lower on sexual function and desire than women without FGM. They did not score lower on Female Sexual Function Index sub-scores for orgasm, desire, and satisfaction and on the Questionnaire d'Image Corporelle but did report significantly more dyspareunia. A larger total volume of clitoris and bulbs did not correlate with higher Female Sexual Function Index and Sexual Desire Inventory scores in women with FGM compared with uncut women who had larger total volume that correlated with higher scores. Women with FGM have sexual erectile tissues for sexual arousal, orgasm, and pleasure. Women with sexual dysfunction should be appropriately counseled and treated.

Ata, Rheanna N; Thompson, J Kevin; Small, Brent J

2013-09-01

The current study was designed to determine whether the inclusion of a disclaimer (i.e., "Retouched photograph aimed at changing a person's physical appearance.") or warning (i.e., "Warning: Trying to look as thin as this model may be dangerous to your health.") added to images of thin/attractive models would affect body dissatisfaction and intent to diet in female undergraduate students (n=342). Participants were randomly assigned to one of four groups: (a) disclaimer, (b) warning, (c) model control, or (d) car control. Results revealed a significant interaction between group and time, whereby only the car control group reported a significant change (i.e., decrease) in body dissatisfaction over time. Groups did not differ on intent to diet measured at post-exposure. The results largely replicate other findings in this area and call into question advocacy efforts to label media images as a strategy to decrease women's identification with the stimuli.

Carotid body tumors (paragangliomas) arise from chemoreceptors located at the carotid bifurcation. In imaging studies, this neoplasm may be confused with other neck neoplasms such as thyroid carcinoma. The purpose of this retrospective, cross-sectional study was to describe computed tomographic (CT) and magnetic resonance imaging (MRI) characteristics of confirmed carotid body tumors in a multi-institutional sample of dogs. A total of 16 dogs met inclusion criteria (14 examined using CT and two with MRI). The most common reason for imaging was a palpable cervical mass or respiratory signs (i.e., dyspnea or increased respiratory noises). The most commonly affected breed was Boston terrier (n = 5). Dogs were predominantly male castrated (n = 10) and the median age was 9 years [range 3-14.5]. Most tumors appeared as a large mass centered at the carotid bifurcation, with poor margination in six dogs and discrete margins in ten dogs. Masses were iso- to hypoattenuating to adjacent muscles in CT images and hyperintense to muscles in T1- and T2-weighted MRI. For both CT and MRI, masses typically showed strong and heterogeneous contrast enhancement. There was invasion into the adjacent structures in 9/16 dogs. In six of these nine dogs, the basilar portion of the skull was affected. The external carotid artery was entrapped in seven dogs. There was invasion into the internal jugular vein in three dogs, and into the external jugular, maxillary, and linguo-facial veins in one dog. Imaging characteristics helped explain some clinical presentations such as breathing difficulties, Horner's syndrome, head tilt, or facial nerve paralysis. © 2015 American College of Veterinary Radiology.

We present a microfluidic chip for immobilizing Drosophila melanogaster larvae for high resolution in vivo imaging. The chip creates a low-temperature micro-environment that anaesthetizes and immobilizes the larva in under 3 minutes. We characterized the temperature distribution within the chip and analyzed the resulting larval body movement using high resolution fluorescence imaging. Our results indicate that the proposed method minimizes submicron movements of internal organs and tissue without affecting the larva physiology. It can be used to continuously immobilize larvae for short periods of time (minutes) or for longer periods (several hours) if used intermittently. The same chip can be used to accommodate and immobilize arvae across all developmental stages (1st instar to late 3rd instar), and loading larvae onto the chip does not require any specialized skills. To demonstrate the usability of the chip, we observed mitochondrial trafficking in neurons from the cell bodies to the axon terminals along with mitochondrial fusion and neuro-synaptic growth through time in intact larvae. Besides studying sub-cellular processes and cellular development, we envision the use of on chip cryo-anesthesia in a wide variety of biological in vivo imaging applications, including observing organ development of the salivary glands, fat bodies and body-wall muscles.

Judging the Difference between Attractiveness and Health: Does Exposure to Model Images Influence the Judgments Made by Men and Women?

2014-01-01

Recent research has shown facial adiposity (apparent weight in the face) to be a significant predictor of both attractiveness and health, thus making it an important determinant of mate selection. Studies looking at the relationship between attractiveness and health have shown that individuals differentiate between the two by preferring a lower weight for attractiveness than for health in female faces. However, these studies have either been correlational studies, or have investigated weight perceived from only the face. These differences have been discussed with regard to sociocultural factors such as pressure from parents, peers and also media, which has been seen to have the highest influence. While exposure to media images has been shown to influence women’s own-body image, no study has yet directly tested the influence of these factors on people’s preferred weight in other women’s bodies. Here we examine how a short exposure to images of models influences men’s and women’s judgments of the most healthy looking and attractive BMI in Malaysian Chinese women’s bodies by comparing differences in preferences (for attractiveness and health) between groups exposed to images of models of varying attractiveness and body weight. Results indicated that participants preferred a lower weight for attractiveness than for health. Further, women’s but not men’s preferred BMI for attractiveness, but not health, was influenced by the type of media images to which they were exposed, suggesting that short term exposure to model images affect women’s perceptions of attractiveness but not health.

Males have been facing increasing pressure from the media to attain a lean, muscular physique, and are at risk for body dissatisfaction, disturbed eating and exercise behaviors, and abuse of appearance- and performance-enhancing drugs (APEDs). The aim of the current study was to examine the relationship between body checking and mood, symptoms of muscle dysmorphia, importance of shape and weight, and APED use in undergraduate males. Body checking in males was correlated with weight and shape concern, symptoms of muscle dysmorphia, depression, negative affect, and APED use. Body checking predicted APED use and uniquely accounted for the largest amount of variance in Muscle Dysmorphic Disorder Inventory (MDDI) scores (16%). Findings support the view that body checking is an important construct in male body image, muscle dysmorphia, and body change strategies and suggest a need for further research.

Fat accumulation is a complex phenotype affected by factors such as neuroendocrine signaling, feeding, activity, and reproductive output. Accordingly, the most informative screens for genes and compounds affecting fat accumulation would be those carried out in whole living animals. Caenorhabditis elegans is a well-established and effective model organism, especially for biological processes that involve organ systems and multicellular interactions, such as metabolism. Every cell in the transparent body of C. elegans is visible under a light microscope. Consequently, an accessible and reliable method to visualize worm lipid-droplet fat depots would make C. elegans the only metazoan in which genes affecting not only fat mass but also body fat distribution could be assessed at a genome-wide scale. Here we present a radical improvement in oil red O worm staining together with high-throughput image-based phenotyping. The three-step sample preparation method is robust, formaldehyde-free, and inexpensive, and requires only 15 minutes of hands-on time to process a 96-well plate. Together with our free and user-friendly automated image analysis package, this method enables C. elegans sample preparation and phenotype scoring at a scale that is compatible with genome-wide screens. Thus we present a feasible approach to small-scale phenotyping and large-scale screening for genetic and/or chemical perturbations that lead to alterations in fat quantity and distribution in whole animals.

Negative body image is the hallmark of anorexia nervosa (AN) and body dysmorphic disorder (BDD). One aspect of body image, appearance-related thoughts, have shown to be a major contributor to relapse, thus further investigation of successful treatment strategies targeting these maladaptive thoughts are warranted. The present study tested an acceptance/mindfulness (AC), a cognitive restructuring (CR), and a distraction strategy with regard to their short-term effectiveness of reducing the frequency of thought occurrence and associated outcomes in participants with AN (n=20), BDD (n=21), and healthy controls (HC; n=22). Although all strategies led to a significant reduction of thought frequency, there was no group × strategy interaction effect in their reduction. Positive affect increased in the BDD group through the AC strategy, but decreased in healthy controls. Acceptance of the thought increased in the CR strategy in AN, whereas that strategy seemed to work least for BDD. Healthy controls showed most acceptance when using distraction. Taken together, the study suggests that all strategies might have their benefits and that it might be worthwhile further investigating differential indication of the strategies with regard to diagnosis and individual factors.

The effect of priming materialism on women's responses to thin-ideal media.

Ashikali, Eleni-Marina; Dittmar, Helga

2012-12-01

Consumer culture is characterized by two prominent ideals: the 'body perfect' and the material 'good life'. Although the impact of these ideals has been investigated in separate research literatures, no previous research has examined whether materialism is linked to women's responses to thin-ideal media. Data from several studies confirm that the internalization of materialistic and body-ideal values is positively linked in women. After developing a prime for materialism (N = 50), we present an experimental examination (N = 155) of the effects of priming materialism on women's responses to thin-ideal media, using multiple outcome measures of state body dissatisfaction. Priming materialism affects women's body dissatisfaction after exposure to thin media models, but differently depending on the dimension of body image measured. The two main novel findings are that (1) priming materialism heightens the centrality of appearance to women's self-concept and (2) priming materialism influences the activation of body-related self-discrepancies (BRSDs), particularly for highly materialistic women. Exposure to materialistic media has a clear influence on women's body image, with trait materialism a further vulnerability factor for negative exposure effects in response to idealized, thin media models. ©2011 The British Psychological Society.

Effect of sway on image fidelity in whole-body digitizing

NASA Astrophysics Data System (ADS)

Corner, Brian D.; Hu, Anmin

1998-03-01

For 3D digitizers to be useful data collection tools in scientific and human factors engineering applications, the models created from scan data must match the original object very closely. Factors such as ambient light, characteristics of the object's surface, and object movement, among others can affect the quality of the image produced by any 3D digitizing system. Recently, Cyberware has developed a whole body digitizer for collecting data on human size and shape. With a digitizing time of about 15 seconds, the effect subject movement, or sway, on model fidelity is an important issue to be addressed. The effect of sway is best measured by comparing the dimensions of an object of known geometry to the model of the same object captured by the digitizer. Since it is difficult to know the geometry of a human body accurately, it was decided to compare an object of simple geometry to its digitized counterpart. Preliminary analysis showed that a single cardboard tube would provide the best artifact for detecting sway. A tube was attached to the subjects using supports that allowed the cylinder to stand away from the body. The stand-off was necessary to minimize occluded areas. Multiple scans were taken of 1 subject and the cylinder extracted from the images. Comparison of the actual cylinder dimensions to those extracted from the whole body images found the effect of sway to be minimal. This follows earlier findings that anthropometric dimensions extracted from whole body scans are very close to the same dimensions measured using standard manual methods. Recommendations for subject preparation and stabilization are discussed.

The rate of prophylactic mastectomies (PM) is increasing. Patients generally report high levels of health related quality of life and satisfaction after the procedure, whereas body image perception and sexuality may be negatively affected. The aim of the study was to evaluate the interest in physical therapy as a means of improving body image and sexuality in women after PM. Patients undergoing PM at Karolinska University Hospital between 2006 and 2010 were eligible. The following patient-reported outcome measures were used at study baseline and 2 years postoperatively: the body image scale (BIS), the sexual activity questionnaire (SAQ), the short-form health survey (SF-36), the hospital anxiety and depression scale (HAD), and a study specific "pain/motion/sensation scale". Out of 125 patients invited to participate in this prospective randomized study, 43 (34%) consented and were randomized into the intervention (n = 24, 56%) or control (n = 19, 44%) groups. There were no statistically significant between-group differences found with respect to BIS, SAQ, SF-36, HAD, and "pain/motion/sensation". Two years postoperatively, more than half of the patients in both groups reported problems like feeling less attractive, less sexually attractive, their body feeling less whole, and being dissatisfied with their body. A majority marked a decreased sensation in breast area. The interest in a physiotherapy intervention was limited among women who had undergone PM. The intervention did not show any substantial effects. A large proportion of patients reported specific body image related and pain/motion/sensation problems postoperatively.

Professional hazards? The impact of models' body size on advertising effectiveness and women's body-focused anxiety in professions that do and do not emphasize the cultural ideal of thinness.

PubMed

Dittmar, Helga; Howard, Sarah

2004-12-01

Previous experimental research indicates that the use of average-size women models in advertising prevents the well-documented negative effect of thin models on women's body image, while such adverts are perceived as equally effective (Halliwell & Dittmar, 2004). The current study extends this work by: (a) seeking to replicate the finding of no difference in advertising effectiveness between average-size and thin models (b) examining level of ideal-body internalization as an individual, internal factor that moderates women's vulnerability to thin media models, in the context of (c) comparing women in professions that differ radically in their focus on, and promotion of, the sociocultural ideal of thinness for women--employees in fashion advertising (n = 75) and teachers in secondary schools (n = 75). Adverts showing thin, average-size and no models were perceived as equally effective. High internalizers in both groups of women felt worse about their body image after exposure to thin models compared to other images. Profession affected responses to average-size models. Teachers reported significantly less body-focused anxiety after seeing average-size models compared to no models, while there was no difference for fashion advertisers. This suggests that women in professional environments with less focus on appearance-related ideals can experience increased body-esteem when exposed to average-size models, whereas women in appearance-focused professions report no such relief.

Appearance feedback in intimate relationships: the role of self-verification and self-enhancement.

PubMed

Brown, Jennifer N; Stukas, Arthur A; Evans, Lynette

2013-01-01

To better understand how body image operates within the context of intimate relationships, we investigated women's responses to appearance feedback from an intimate partner. Participants (N=192) imagined receiving feedback from their partner that was either consistent with their own appearance self-view (i.e., self-verifying), more positive (i.e., self-enhancing), or less positive (i.e., devaluing), and then provided their affective and cognitive reactions. As expected, women's perceptions of their own appearance moderated their reactions. Women with more negative self-views felt happier with enhancing feedback, but thought that it meant their partner understood them less well. They also felt less happy when they received verifying feedback, but felt more understood by their partners. Thus, women with body image dissatisfaction may find themselves stuck in the "cognitive-affective crossfire" reacting ambivalently whether their partner enhances their appearance or confirms their negative self-views. Further examination of partners' actual feedback is needed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Body-related pride in young adults: an exploration of the triggers, contexts, outcomes and attributions.

2013-06-01

This study explored body-related emotional experiences of pride in young adult males (n=138) and females (n=165). Data were collected using a relived emotion task and analyzed using inductive content analysis. Thirty-nine codes were identified and grouped into six categories (triggers, contexts, cognitive attributions, and affective, cognitive, and behavioral outcomes) for each of two themes (hubristic and authentic pride). Hubristic pride triggers included evaluating appearance/fitness as superior. Cognitions centered on feelings of superiority. Behaviors included strategies to show off. Triggers for authentic pride were personal improvements/maintenance in appearance and meeting or exceeding goals. Feeling accomplished was a cognitive outcome, and physical activity was a behavioral strategy. Contexts for the experience of both facets of pride primarily involved sports settings, swimming/beach, and clothes shopping. These findings provide theoretical support for models of pride as it applies to body image, and advances conceptual understanding of positive body image. Copyright © 2013 Elsevier Ltd.

Helfert, Susanne; Warschburger, Petra

2011-03-01

The current study explores the role of appearance-related social pressure regarding changes in body image in adolescent girls (n=236) and boys (n=193) over a 1-year-period. High school students aged 11-16 completed measures of body dissatisfaction (i.e., weight and muscle concerns) and appearance-related social pressure from peers and parents. Three aspects proved to be particularly crucial: Parental encouragement to control weight and shape was a strong predictor of weight concerns in boys and girls alike; influences of friends affected gender-specific body image concerns by leading to weight concerns in girls and muscle concerns in boys; finally appearance-based exclusion was a predictor of weight concerns in boys. The findings provide longitudinal evidence for the crucial impact of appearance-related social pressure and suggest that a detailed assessment of different types of social impacts can identify concrete targets for effective prevention and therapy for weight-related problems among adolescents.

Plant oleosomes are uniquely emulsified lipid reservoirs that serve as the primary energy source during seed germination. These oil bodies undergo significant changes regarding their size, composition and structure during normal seedling development; however, a detailed characterization of these oil body dynamics, which critically affect oil body extractability and nutritional value, has remained challenging because of a limited ability to monitor oil body location and composition during germination in situ. Here, we demonstrate via in situ, label-free imaging that oil bodies are highly dynamic intracellular organelles that are morphologically and biochemically remodelled extensively during germination. Label-free, coherent Raman microscopy (CRM) combined with bulk biochemical measurements revealed the temporal and spatial regulation of oil bodies in native soya bean cotyledons during the first eight days of germination. Oil bodies undergo a cycle of growth and shrinkage that is paralleled by lipid and protein compositional changes. Specifically, the total protein concentration associated with oil bodies increases in the first phase of germination and subsequently decreases. Lipids contained within the oil bodies change in saturation and chain length during germination. Our results show that CRM is a well-suited platform to monitor in situ lipid dynamics and local chemistry and that oil bodies are actively remodelled during germination. This underscores the dynamic role of lipid reservoirs in plant development. PMID:27798279

Peyronie's disease (PD) has a negative impact on men's sexual functioning and quality of life, but little is known about why some men cope better than others and what the effects of PD are on their relationships. The aims of the present study were to describe negative affect, pain, and relationship and sexual satisfaction in men with PD, and to explore their psychosocial correlates. Participants were 110 men diagnosed with PD. All men completed questionnaires. The main outcome measures were as follows: Global Measure of Sexual Satisfaction, Dyadic Adjustment Scale, McGill Pain Questionnaire, and Negative Affect Scale. The predictor variables were the following: Experience of Shame Scale, Body Esteem Scale, Body Image Self-Consciousness Scale, Index of Male Genital Image, a modified Pain Catastrophizing Scale, and a modified Multidimensional Pain Inventory. Although men with PD had mean sexual/relationship satisfaction and negative affect scores indicating mild impairment, there was a wide range of variation, with 42% to 52% scoring in the clinical range. Catastrophizing was significantly associated with reduced sexual satisfaction and increased negative affect and pain. Shame was also associated with increased negative affect. The significant associations of relationship satisfaction were partner responses and shame. Given the lack of curative treatment in PD, understanding why some men cope better than others may guide therapy. Shame, catastrophizing, and partner responses may be important therapeutic targets.

Investigations on the effect of frequency and noise in a localization technique based on microwave imaging for an in-body RF source

Localization of a wireless capsule endoscope finds many clinical applications from diagnostics to therapy. There are potentially two approaches of the electromagnetic waves based localization: a) signal propagation model based localization using a priori information about the persons dielectric channels, and b) recently developed microwave imaging based localization without using any a priori information about the persons dielectric channels. In this paper, we study the second approach in terms of a variety of frequencies and signal-to-noise ratios for localization accuracy. To this end, we select a 2-D anatomically realistic numerical phantom for microwave imaging at different frequencies. The selected frequencies are 13:56 MHz, 431:5 MHz, 920 MHz, and 2380 MHz that are typically considered for medical applications. Microwave imaging of a phantom will provide us with an electromagnetic model with electrical properties (relative permittivity and conductivity) of the internal parts of the body and can be useful as a foundation for localization of an in-body RF source. Low frequency imaging at 13:56 MHz provides a low resolution image with high contrast in the dielectric properties. However, at high frequencies, the imaging algorithm is able to image only the outer boundaries of the tissues due to low penetration depth as higher frequency means higher attenuation. Furthermore, recently developed localization method based on microwave imaging is used for estimating the localization accuracy at different frequencies and signal-to-noise ratios. Statistical evaluation of the localization error is performed using the cumulative distribution function (CDF). Based on our results, we conclude that the localization accuracy is minimally affected by the frequency or the noise. However, the choice of the frequency will become critical if the purpose of the method is to image the internal parts of the body for tumor and/or cancer detection.

Patients with anorexia nervosa (AN) have a persistent distorted experience of the size of their body. Previously we found that the Rubber Hand Illusion improves hand size estimation in this group. Here we investigated whether a Full Body Illusion (FBI) affects body size estimation of body parts more emotionally salient than the hand. In the FBI, analogue to the RHI, participants experience ownership over an entire virtual body in VR after synchronous visuo-tactile stimulation of the actual and virtual body. We asked participants to estimate their body size (shoulders, abdomen, hips) before the FBI was induced, directly after induction and at ~2 hour 45 minutes follow-up. The results showed that AN patients (N = 30) decrease the overestimation of their shoulders, abdomen and hips directly after the FBI was induced. This effect was strongest for estimates of circumference, and also observed in the asynchronous control condition of the illusion. Moreover, at follow-up, the improvements in body size estimation could still be observed in the AN group. Notably, the HC group (N = 29) also showed changes in body size estimation after the FBI, but the effect showed a different pattern than that of the AN group. The results lead us to conclude that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts. As such this study offers novel starting points from which new interventions for body image disturbance in AN can be developed.

Understanding the factors that contribute to health-related quality of life (HRQOL) is critical for developing the most appropriate interventions for improving or maintaining the HRQOL in polycystic ovary syndrome (PCOS) patients. This study sought to determine the most significant predictors of the HRQOL in patients with PCOS. This was a cross-sectional study of 300 women with PCOS that was carried out in Kashan, Iran. A sample of women with PCOS was entered into the study and completed the following questionnaires: the Hospital Anxiety and Depression Scale, the Body Image Concern Inventory (BICI), the Rosenberg's Self-Esteem Scale score, the modified polycystic ovary syndrome health-related quality of life questionnaire, the Female Sexual Function Index. Both direct and indirect relationships among clinical severity, psychological status, self-esteem, body image, and sexual function as independent predictors of HRQOL were examined using structural equation modeling (SEM) analysis. By using the SEM, we simultaneously test a number of possible hypotheses concerning the interrelations among the predictors of HRQOL in PCOS patients. In relation with severity of PCOS, reproductive history and menstrual status explained a high proportion of the variance of clinical variables (factor loading 0.37 and 0.34, respectively). The highest effect on HRQL was exerted by indirect effect of clinical factor (β = 0.90), self-esteem (β = 1.12), body image (β = 1.06), and sexual function (β = 0.26) that influenced negatively HRQOL. The infertility and menstrual domains were the most affected areas of HRQOL. In relation with sexual dysfunction, the most affected domains were desire and arousal. The highest effect of PCOS symptoms on HRQOL impairment among patients was exerted by self-esteem, body image, and sexual dysfunction. With regard to HRQOL in clinical routine, we conclude these mediating factors should be taken into consideration and adequately treated if present. © 2013 International Society for Sexual Medicine.

1. Specific legal requirements for keeping pullets are not available in the European Union. However, two of the most important rearing factors for pullets are sufficient perching and feeder space. Both factors represent horizontal space dimensions which derive from the body width of the birds. 2. The body width of two strains of layer pullets (brown (BL) and white (WL) layer pullets) based on the measurement of distances in digital images was conducted on front-view digital photographs of BL and WL pullets taken at 8, 12 and 19 weeks of life. 3. Depending on live weight, age and body position, BL pullets measured an average body width between 10.70 ± 1.10 and 13.96 ± 1.11 cm. The width of WL pullets ranged from 10.30 ± 0.86 to 13.00 ± 1.14 cm. 4. Compared with WL, BL pullets occupied more horizontal space during rearing. Age influenced the body width of BL and WL pullets at the end of rearing. The tested body positions of the pullets did not affect the measured body width. 5. The biometric data obtained in this study are a useful basis for developing legal requirements for pullets, especially for defining minimum perch width and feeder space allowances.

Illusory Changes in Body Size Modulate Body Satisfaction in a Way That Is Related to Non-Clinical Eating Disorder Psychopathology

PubMed Central

Preston, Catherine; Ehrsson, H. Henrik

2014-01-01

Historically, body size overestimation has been linked to abnormal levels of body dissatisfaction found in eating disorders. However, recently this relationship has been called into question. Indeed, despite a link between how we perceive and how we feel about our body seeming intuitive, until now lack of an experimental method to manipulate body size has meant that a causal link, even in healthy participants, has remained elusive. Recent developments in body perception research demonstrate that the perceptual experience of the body can be readily manipulated using multisensory illusions. The current study exploits such illusions to modulate perceived body size in an attempt to influence body satisfaction. Participants were presented with stereoscopic video images of slimmer and wider mannequin bodies viewed through head-mounted displays from first person perspective. Illusory ownership was induced by synchronously stroking the seen mannequin body with the unseen real body. Pre and post-illusion affective and perceptual measures captured changes in perceived body size and body satisfaction. Illusory ownership of a slimmer body resulted in participants perceiving their actual body as slimmer and giving higher ratings of body satisfaction demonstrating a direct link between perceptual and affective body representations. Change in body satisfaction following illusory ownership of a wider body, however, was related to degree of (non-clinical) eating disorder psychopathology, which can be linked to fluctuating body representations found in clinical samples. The results suggest that body perception is linked to body satisfaction and may be of importance for eating disorder symptomology. PMID:24465698

Eating disorders and body image concerns in Asian American women: assessment and treatment from a multicultural and feminist perspective.

2007-01-01

Eating disorders are one of the most lethal psychiatric illnesses and affect millions of individuals worldwide. While they have been more typically attributed to middle class, Caucasian, adolescent females, current research suggests that there is a similar prevalence of eating disorders and their symptoms, especially body dissatisfaction, among Asian American girls and women. Despite this, very little research has investigated how culture and gender may impact the assessment and treatment of eating disorders for Asian American women. This review examines the literature on the prevalence of eating disorders and negative body image in Asian American women and describes current research on the efficacy of a variety of theoretical approaches for treatment, including psychodynamic, cognitive-behavioral, and feminist perspectives. Recommendations for considering culture and gender when working clinically with Asian American women who experience eating concerns as well as suggestions for future research directions are provided.

[Factors influencing self-perception of overweight people].

2013-11-01

Shaping of self-perception is among others influenced by physical, interpersonal, emotional, and cultural factors. In self-perception of overweight people an important role is played by interpersonal factors, which include the opinions of others and the relationship with the surrounding. The evaluation of the body image is also affect by sociocultural factors including the media, which create an unrealistic and impossible to achieve ideal of beauty. Contemporary ideal of beauty, where a slim figure is dominant, more frequently contributes to the occurrence of discrimination and stigmatization of overweight people. This phenomenon causes negative self-perception leading to the occurrence of such emotional problems as low self-esteem, lack of confidence, depression and anxiety disorders. Overweight children and adolescents are also frequently stigmatized and discriminated because of their body weight, which results in the development of a negative body image that may lead to low self-esteem and symptoms of depression.

Making the invisible body visible. Bone scans, osteoporosis and women's bodily experiences.

The imaging technology of bone scans allows visualization of the bone structure, and determination of a numerical value. Both these are subjected to professional interpretation according to medical (epidemiological) evidence to estimate the individual's risk of fractures. But when bodily experience is challenged by a visual diagnosis, what effect does this have on an individual? The aim of this study was to explore women's bodily experiences after a bone scan and to analyse how the scan affects women's self-awareness, sense of bodily identity and integrity. We interviewed 16 Danish women (aged 61-63) who had had a bone scan for osteoporosis. The analysis was based on Merleau-Ponty's perspective of perception as an embodied experience in which bodily experience is understood to be the existential ground of culture and self. Women appeared to take the scan literally and planned their lives accordingly. They appeared to believe that the 'pictures' revealed some truth in themselves. The information supplied by the scan fostered a new body image. The women interpreted the scan result (a mark on a curve) to mean bodily fragility which they incorporated into their bodily perception. The embodiment of this new body image produced new symptom interpretations and preventive actions, including caution. The result of the bone scan and its cultural interpretation triggered a reconstruction of the body self as weak with reduced capacity. Women's interpretation of the bone scan reorganized their lived space and time, and their relations with others and themselves. Technological information about osteoporosis appeared to leave most affected women more uncertain and restricted rather than empowered. The findings raise some fundamental questions concerning the use of medical technology for the prevention of asymptomatic disorders.

The primary and secondary mirrors of onaxis three mirror anastigmatic (TMA) space camera are connected and supported by its front mirror-body structure, which affects both imaging performance and stability of the camera. In this paper, the carbon fiber reinforced plastics (CFRP) thin-walled cylinder and titanium alloy connecting rod have been used for the front mirror-body opto-mechanical structure of the long-focus on-axis and TMA space camera optical system. The front mirror-body component structure has then been optimized by finite element analysis (FEA) computing. Each performance of the front mirror-body structure has been tested by mechanics and vacuum experiments in order to verify the validity of such structure engineering design.

Studies regarding the effects of aesthetic outcomes after breast cancer surgery on quality of life (QoL) have yielded inconsistent results. This study analyzed the aesthetic outcomes and QoL of women who underwent breast conserving surgery (BCS) or total mastectomy with immediate reconstruction (TMIR) using objective and validated methods. QoL questionnaires (EORTC QLQ-C30, BR23, and HADs) were administered at least 1 year after surgery and adjuvant therapy to 485 patients who underwent BCS, 46 who underwent TMIR, and 87 who underwent total mastectomy (TM) without reconstruction. Aesthetic results were evaluated using BCCT.core software and by a panel of physicians. Patients' body image perception was assessed using the body image scale (BIS). QoL outcomes, including for social and role functioning, fatigue, pain, body image, and arm symptoms, were significantly better in the BCS and TMIR groups than in the TM group (p<0.05 each). BIS was significantly better in the BCS than in the TM or TMIR group (p<0.001 each). In the BCS and TMIR groups, general QoL factors were not significantly associated with objective cosmetic outcomes, except for body image in the QLQ-BR23. In contrast, patients with poorer BIS score reported lower QoL in almost all items of the QLQ-C30, BR23, and HADS (p<0.05 each). In conclusion, BCS and TMIR enhanced QoL compared with TM. Among BCS and TMIR patients, objectively measured cosmetic results did not affect general QoL. Self-perception of body image seems to be more important for QoL after breast cancer surgery.

Acupuncture stimulation increases local blood flow around the site of stimulation and induces signal changes in brain regions related to the body matrix. The rubber hand illusion (RHI) is an experimental paradigm that manipulates important aspects of bodily self-awareness. The present study aimed to investigate how modifications of body ownership using the RHI affect local blood flow and cerebral responses during acupuncture needle stimulation. During the RHI, acupuncture needle stimulation was applied to the real left hand while measuring blood microcirculation with a LASER Doppler imager (Experiment 1, N = 28) and concurrent brain signal changes using functional magnetic resonance imaging (fMRI; Experiment 2, N = 17). When the body ownership of participants was altered by the RHI, acupuncture stimulation resulted in a significantly lower increase in local blood flow (Experiment 1), and significantly less brain activation was detected in the right insula (Experiment 2). This study found changes in both local blood flow and brain responses during acupuncture needle stimulation following modification of body ownership. These findings suggest that physiological responses during acupuncture stimulation can be influenced by the modification of body ownership. PMID:25285620

2013-09-01

Social comparison theory suggests that evaluating the self in comparison with others (e.g., peers, celebrities, models) can influence body image. Experimental studies that have tested effects of viewing idealized images in the media often show that women feel worse about themselves after seeing images that illustrate the beauty ideal. Twitter presents a naturally occurring opportunity to study viewers' reactions. An analysis was conducted of 977 tweets sent immediately before and during the 2011 Victoria's Secret Fashion Show that reference the show. Although the majority were idiosyncratic remarks, many tweets contain evidence of upward social comparisons to the fashion models. There were tweets about body image, eating disorders, weight, desires for food or alcohol, and thoughts about self-harm. The results support social comparison theory, and suggest that vulnerable viewers could experience negative affect, or even engage in harmful behaviors, during or after viewing the show or others like it.

The face of appearance-related social pressure: gender, age and body mass variations in peer and parental pressure during adolescence.

Appearance-related social pressure plays an important role in the development of a negative body image and self-esteem as well as severe mental disorders during adolescence (e.g. eating disorders, depression). Identifying who is particularly affected by social pressure can improve targeted prevention and intervention, but findings have either been lacking or controversial. Thus the aim of this study is to provide a detailed picture of gender, weight, and age-related variations in the perception of appearance-related social pressure by peers and parents. 1112 German students between grades 7 and 9 (mean age: M = 13.38, SD = .81) filled in the Appearance-Related Social Pressure Questionnaire (German: FASD), which considers different sources (peers, parents) as well as various kinds of social pressure (e.g. teasing, modeling, encouragement). Girls were more affected by peer pressure, while gender differences in parental pressure seemed negligible. Main effects of grade-level suggested a particular increase in indirect peer pressure (e.g. appearance-related school and class norms) from early to middle adolescence. Boys and girls with higher BMI were particularly affected by peer teasing and exclusion as well as by parental encouragement to control weight and shape. The results suggest that preventive efforts targeting body concerns and disordered eating should bring up the topic of appearance pressure in a school-based context and should strengthen those adolescents who are particularly at risk - in our study, girls and adolescents with higher weight status. Early adolescence and school transition appear to be crucial periods for these efforts. Moreover, the comprehensive assessment of appearance-related social pressure appears to be a fruitful way to further explore social risk-factors in the development of a negative body image.

Improving language models for radiology speech recognition.

Paulett, John M; Langlotz, Curtis P

2009-02-01

Speech recognition systems have become increasingly popular as a means to produce radiology reports, for reasons both of efficiency and of cost. However, the suboptimal recognition accuracy of these systems can affect the productivity of the radiologists creating the text reports. We analyzed a database of over two million de-identified radiology reports to determine the strongest determinants of word frequency. Our results showed that body site and imaging modality had a similar influence on the frequency of words and of three-word phrases as did the identity of the speaker. These findings suggest that the accuracy of speech recognition systems could be significantly enhanced by further tailoring their language models to body site and imaging modality, which are readily available at the time of report creation.

Materials and Methods: A total of 76 quarters of lactating HF crossbred (Bos indicus × Bos taurus) cows (n=19) were monitored for body temperature (i.e., eye temperature) and udder skin surface temperature (USST) before milking using forward-looking infrared (FLIR) i5 camera. Milk samples were collected from each quarter and screened for mastitis using Somatic Cell Count (SCC), Electrical Conductivity (EC), and California mastitis test. Thermographic images were analyzed using FLIR Quick Report 1.2 image analysis software. Data on body and USST were compiled and analyzed statistically using SPSS 16.0 and Sigmaplot 11. Results: The mean±standard deviation (SD) body (37.23±0.08°C) and USST (37.22±0.04°C) of non-mastitic cow did not differ significantly; however, the mean USST of the mastitis-affected quarters were significantly higher than the body temperature and USST of unaffected quarters (p<0.001). The mean±SD USST of the subclinical mastitis (SCM) and clinical mastitis-affected quarters were 38.08±0.17 °C and 38.25±0.33 °C, respectively, which is 0.72 and 1.05 °C higher than the USST temperature of unaffected quarters. The USST was positively correlated with EC (r=0.95) and SCC (r=0.93). The receiver operating characteristic curve analysis revealed a higher sensitivity for USST in early prediction of SCM with a cut-off value of >37.61°C. Conclusion: It is concluded that infrared thermal imaging technique could be used as a potential noninvasive, quick cow-side diagnostic technique for screening and early detection of SCM and clinical mastitis in crossbred cows.

To compare two measurement methods for body hair. Calibration of computer assisted image analysis after manual processing (CAIAMP) showed variation <4% for thickness and <2.3% for densities. Images from 6 body sites with 'good natural contrast between hair and skin' were taken before hair dye, after hair dye or after hair length reduction without hair extraction or destruction. Data in the same targets were compared with Trichoscan(™) quoted for 'unambiguous evaluation of the hair growth after shaving'. CAIAMP detected a total of 337 hair and showed no statistically significant differences with the three procedures confirming 'good natural contrast between hair and skin' and that reduction methods did not affect hair counts. While CAIAMP found a mean number of 19 thick hair (≥30 μm) before dye, 18 after dye and 20 after hair reduction, Trichoscan(™) found in the same sites respectively 44, 73 and 61. Trichoscan(™) generated counts differed statistically significantly from CAIAMP-data. Automated analyses were considered un-specifically influenced by hair medulla and natural or artificial skin background. Quality control including all steps of human intervention and measurement technology are mandatory for body hair measurements during experimental or clinical trials on body hair grooming, shaving or removal. © 2015 John Wiley & Sons A/S.

Electrical Impedance Tomography (EIT) is a promising application that displays changes in conductivity within a body. The basic principle of the method is the repeated measurement of surface voltages of a body, which are a result of rolling injection of known and small-volume sinusoidal AC current to the body through the electrodes attached to its surface. This method finds application in biomedicine, biology and geology. The objective of this paper is to present the applications of Electrical Impedance Tomography, along with the method's capabilities and limitations due to the electrical properties of the human body. For this purpose, investigation of existing literature has been conducted, using electronic databases, PubMed, Google Scholar and IEEE Xplore. In addition, there was a secondary research phase, using paper citations found during the first research phase. It should be noted that Electrical Impedance Tomography finds use in a plethora of medical applications, as the different tissues of the body have different conductivities and dielectric constants. Main applications of EIT include imaging of lung function, diagnosis of pulmonary embolism, detection of tumors in the chest area and diagnosis and distinction of ischemic and hemorrhagic stroke. EIT advantages include portability, low cost and safety, which the method provide, since it is a noninvasive imaging method that does not cause damage to the body. The main disadvantage of the method, which blocks its wider spread, appears in the image composition from the voltage measurements, which are conducted by electrodes placed on the periphery of the body, because the injected currents are affected nonlinearly by the general distribution of the electrical properties of the body. Furthermore, the complex impedance of the skin-electrode interface can be modelled by using a capacitor and two resistor, as a result of skin properties. In conclusion, Electrical Impedance Tomography is a promising method for the development of noninvasive diagnostic medicine, since it is able to provide imaging of the interior of the human body in real time without causing harm or putting the human body in risk.

Illusory Obesity Triggers Body Dissatisfaction Responses in the Insula and Anterior Cingulate Cortex

Preston, Catherine; Ehrsson, H. Henrik

2016-01-01

In today's Western society, concerns regarding body size and negative feelings toward one's body are all too common. However, little is known about the neural mechanisms underlying negative feelings toward the body and how they relate to body perception and eating-disorder pathology. Here, we used multisensory illusions to elicit illusory ownership of obese and slim bodies during functional magnetic resonance imaging. The results implicate the anterior insula and the anterior cingulate cortex in the development of negative feelings toward the body through functional interactions with the posterior parietal cortex, which mediates perceived obesity. Moreover, cingulate neural responses were modulated by nonclinical eating-disorder psychopathology and were attenuated in females. These results reveal how perceptual and affective body representations interact in the human brain and may help explain the neurobiological underpinnings of eating-disorder vulnerability in women.

Although previous research showed that the thin ideal provided by the media affects body image and eating behaviour in young children, less is known about specific media contents that are related to body image and eating behaviour. This study tested the associations between watching soaps and music television and body dissatisfaction and restrained eating directly, and indirectly through thin ideal internalisation. We conducted a survey in class, in which 245 girls (aged 7-9) completed scales on their television watching behaviour, thin ideal internalisation, body dissatisfaction and restrained eating. Additionally, height and weight were measured. Watching soaps and music television often was associated with higher thin ideal internalisation, which in turn was associated with higher body dissatisfaction and restrained eating. Furthermore, a direct association between watching soaps and music television and restrained eating was found. If watching other types of children's programmes or maternal encouragement to be thin were included in the models, watching soaps and music television remained an important factor, especially with regard to restrained eating. Therefore, our results suggest that if young girls watch soaps and music television often, this is related to higher restrained eating and body dissatisfaction, directly or indirectly, through higher thin ideal internalisation.

The aims were to investigate how the body image is affected in fibromyalgia syndrome (FMS) in comparison to healthy people, as well as to explore the relationship of the body image with the level of pain, functional status, severity of depression, and quality of life (QoL). Demographic variables, symptoms of fibromyalgia, and number of fibromyalgia tender points for 51 patients with FMS and 41 control subjects were recorded. All patients were asked to mark the level of pain on visual analogue scale (VAS). Six-minute walking test was recorded for functional assessment. The impact of the disease was evaluated by fibromyalgia impact questionnaire (FIQ). All patients were asked to complete body image scale (BIS), Beck depression inventory (BDI), and short form-36 (SF-36). There were no differences between groups with regard to demographic variables (p>0.05). Mean VAS was 7.5±1.4 for the patients with FMS and 0.3±0.4 for control subjects (p<0.05). Mean FIQ was 70.8±13.2 and 8.2±9.6 for the FMS and control groups, respectively (p<0.05). Mean BIS and BDI were 106.5±24.0 and 20.2±11.2 for FMS group and 66.3±23.4 and 3.4±4.0 for control group, respectively (p<0.05). SF-36 subscores were found to be significantly lower in patients with FMS than control subjects (p<0.05), except for the social function subscore. BIS score had significant relationships both with VAS (r=0.843) and FIQ (r=0.290) in patients with FMS (p<0.05). There were significant relationships between BIS scores and SF-36 pain (r= -0.288), energy/vitality (r= -0.519), mental health (r= -0.442), and general health (r= -0,492) subscores (p<0.05). Body image was associated with VAS in the multivariate linear regression analysis. The results of the present study indicate that body image is disturbed in patients with FMS compared to control subjects. For the evaluation of the level of pain, impact of the disease, and QoL in patients with FMS, it would be useful to consider the relationship of the body image disturbance with these parameters.

In Indonesia, disorders of sex development (DSDs) are not well recognized and medical care for affected individuals is scarce. Consequently, many patients live with ambiguous genitalia and appearance. We compared reported outcomes on body image, sexual functioning, and sexual orientation of 39 adults with DSDs (aged 18 to 41) and 39 healthy controls matched for gender, age, and residential setting (urban, suburban, rural). Differences in gender and treatment status (treated or untreated) were also explored. On body image, adults with DSDs reported dissatisfaction with sex-related body parts. Compared to the matched controls, women with DSDs reported greater sexual distress, and men with DSDs reported lower erectile and ejaculation frequencies, and more dissatisfaction with sexual life but not with sexual desire and activities. Men with DSDs who had undergone genital surgery reported higher erectile and ejaculation frequencies than untreated men. More women than men in the DSDs group reported a nonexclusive heterosexual orientation. DSDs and infertility had a great impact on sexuality. Fear of ostracism complicated DSD acceptance. Findings were compared to those of Western studies. Based on these results, education about DSDs and their psychosexual consequences may help reduce the sexual distress and problems in adults with DSDs and improve quality of life.

The aim of this study was to report our early experience with (18)F-fluoride PET/CT for detecting lesions and evaluate the usefulness of this modality in the assessment of multiple myeloma (MM). (18)F-fluoride PET/CT and (99m)Tc-MDP bone scintigraphy (BS) studies from 7 myeloma patients (4 male and 3 female, mean age 55 years) diagnosed according to standard criteria were reviewed retrospectively. Two reviewers visually and quantitatively analyzed the images and recorded their findings after reaching a consensus. Diagnostic certainty regarding the presence or absence of myeloma lesions was evaluated according to the reference standard consisting of whole-body magnetic resonance imaging and whole-body X-ray. A total of 93 affected areas were definite according to the reference standard. Of these, 83 affected areas (89 %) were identified on (18)F-fluoride PET/CT, whereas 54 affected areas (58 %) were found on BS. Mean SUVmax in the affected areas was 9.8 ± 3.2 (standard deviation) ranging from 5.0 to 21.2. A total of s17 lesions with bone fracture were also detected by (18)F-fluoride PET/CT and 2 lesions (12 %) were negative on BS. Our result showed that (18)F-fluoride PET was a possible modality to detect areas of lesions in patients with MM.

Background Patients with anorexia nervosa (AN) have a persistent distorted experience of the size of their body. Previously we found that the Rubber Hand Illusion improves hand size estimation in this group. Here we investigated whether a Full Body Illusion (FBI) affects body size estimation of body parts more emotionally salient than the hand. In the FBI, analogue to the RHI, participants experience ownership over an entire virtual body in VR after synchronous visuo-tactile stimulation of the actual and virtual body. Methods and Results We asked participants to estimate their body size (shoulders, abdomen, hips) before the FBI was induced, directly after induction and at ~2 hour 45 minutes follow-up. The results showed that AN patients (N = 30) decrease the overestimation of their shoulders, abdomen and hips directly after the FBI was induced. This effect was strongest for estimates of circumference, and also observed in the asynchronous control condition of the illusion. Moreover, at follow-up, the improvements in body size estimation could still be observed in the AN group. Notably, the HC group (N = 29) also showed changes in body size estimation after the FBI, but the effect showed a different pattern than that of the AN group. Conclusion The results lead us to conclude that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts. As such this study offers novel starting points from which new interventions for body image disturbance in AN can be developed. PMID:27711234

Pharmacokinetics of the tri[8-carboxy-2,2,6,6-tetrakis(2-hydroxymethyl)benzo[1,2-d:4,5-d']bis(1,3)dithio-4-yl]methyl radical (Oxo63) after a single bolus and/or continuous intravenous infusion was investigated in tumor-bearing C3H mice with or without body temperature control while under anesthesia. The in vivo time course of Oxo63 in blood was measured using X-band electron paramagnetic resonance spectroscopy. Distribution of Oxo63 in normal muscle and tumor tissues was obtained using a surface coil resonator and a 700-MHz electron paramagnetic resonance spectrometer. The whole-body distribution of Oxo63 was obtained by 300-MHz continuous-wave electron paramagnetic resonance imaging. The high-resolution 300-MHz time-domain electron paramagnetic resonance imaging was also carried out to probe the distribution of Oxo63. Urination of mice was retarded at low body temperature, causing the concentration of Oxo63 in blood to attain high levels. However, the concentration of Oxo63 in tumor tissue was lower with no control of body temperature than active body temperature control. The nonsystemized blood flow in the tumor tissues may pool Oxo63 at lower body temperature. Pharmacokinetics of the contrast agent were found to be significantly affected by body temperature of the experimental animal, and can influence the probe distribution and the image patterns.

To build and evaluate a small-footprint, lightweight, high-performance 3T MRI scanner for advanced brain imaging with image quality that is equal to or better than conventional whole-body clinical 3T MRI scanners, while achieving substantial reductions in installation costs. A conduction-cooled magnet was developed that uses less than 12 liters of liquid helium in a gas-charged sealed system, and standard NbTi wire, and weighs approximately 2000 kg. A 42-cm inner-diameter gradient coil with asymmetric transverse axes was developed to provide patient access for head and extremity exams, while minimizing magnet-gradient interactions that adversely affect image quality. The gradient coil was designed to achieve simultaneous operation of 80-mT/m peak gradient amplitude at a slew rate of 700 T/m/s on each gradient axis using readily available 1-MVA gradient drivers. In a comparison of anatomical imaging in 16 patients using T 2 -weighted 3D fluid-attenuated inversion recovery (FLAIR) between the compact 3T and whole-body 3T, image quality was assessed as equivalent to or better across several metrics. The ability to fully use a high slew rate of 700 T/m/s simultaneously with 80-mT/m maximum gradient amplitude resulted in improvements in image quality across EPI, DWI, and anatomical imaging of the brain. The compact 3T MRI system has been in continuous operation at the Mayo Clinic since March 2016. To date, over 200 patient studies have been completed, including 96 comparison studies with a clinical 3T whole-body MRI. The increased gradient performance has reliably resulted in consistently improved image quality. © 2018 International Society for Magnetic Resonance in Medicine.

Localization of a wireless capsule endoscope finds many clinical applications from diagnostics to therapy. There are potentially two approaches of the electromagnetic waves based localization: a) signal propagation model based localization using a priori information about the persons dielectric channels, and b) recently developed microwave imaging based localization without using any a priori information about the persons dielectric channels. In this paper, we study the second approach in terms of a variety of frequencies and signal-to-noise ratios for localization accuracy. To this end, we select a 2-D anatomically realistic numerical phantom for microwave imaging at different frequencies. The selected frequencies are 13:56 MHz, 431:5 MHz, 920 MHz, and 2380 MHz that are typically considered for medical applications. Microwave imaging of a phantom will provide us with an electromagnetic model with electrical properties (relative permittivity and conductivity) of the internal parts of the body and can be useful as a foundation for localization of an in-body RF source. Low frequency imaging at 13:56 MHz provides a low resolution image with high contrast in the dielectric properties. However, at high frequencies, the imaging algorithm is able to image only the outer boundaries of the tissues due to low penetration depth as higher frequency means higher attenuation. Furthermore, recently developed localization method based on microwave imaging is used for estimating the localization accuracy at different frequencies and signal-to-noise ratios. Statistical evaluation of the localization error is performed using the cumulative distribution function (CDF). Based on our results, we conclude that the localization accuracy is minimally affected by the frequency or the noise. However, the choice of the frequency will become critical if the purpose of the method is to image the internal parts of the body for tumor and/or cancer detection.

How do you define body image? Exploring conceptual gaps in understandings of body image at an exercise facility.

The definition of body image has evolved within research; however, less is known about the layperson's understanding of the construct. This study explored how members and student trainees of an exercise facility (designed for older adults, people with physical disability, and those with cardiac complications) defined body image. Nineteen participants completed a one-on-one interview, and seven of those participants took part in six additional focus group meetings. The following main themes were found: stereotypical assumptions about body image (e.g., it is solely a person's weight or merely a woman's issue), body image continua for positive and negative body image, degree of complexity of body image dimensions, broad considerations of body image (e.g., it is self-esteem), and limited knowledge about body image. These findings suggest a need for knowledge translation between researchers and the general public which informs future body image program design. Copyright © 2017 Elsevier Ltd. All rights reserved.

To ascertain what meaning individuals attach to perceiving images of their own interior body and how the images and their meanings affect the clinical consultation. Face-to-face semistructured interviews. 25 adult patients in southern England who, within the preceding 12 months, had been referred for diagnostic imaging. Community. For patients, being shown their own X-rays, MRIs or CT images creates a variety of effects: (1) a sense of better understanding of the diagnosis; (2) validation of their sensory and emotional response to the illness or injury and (3) an alteration to the tenor and nature of the clinical encounter between patient and physician. In addition to meanings attached to these images, patients also impute meaning to the physician's decision not to share an image with them. The desire to see their image was greater in those patients with a skeletal injury; patients are less keen on viewing abdominal or other soft tissue images. Viewing images of one's interior, invisible body is powerful and resonant in a number of ways. The experience of not seeing, whether through the patient's or the physician's choice, is also fraught with meaning. Published by the BMJ Publishing Group Limited.

2010-03-01

Extant body image research has provided a rich understanding of negative body image but a rather underdeveloped depiction of positive body image. Thus, this study used Grounded Theory to analyze interviews from 15 college women classified as having positive body image and five body image experts. Many characteristics of positive body image emerged, including appreciating the unique beauty and functionality of their body, filtering information (e.g., appearance commentary, media ideals) in a body-protective manner, defining beauty broadly, and highlighting their body's assets while minimizing perceived imperfections. A holistic model emerged: when women processed mostly positive and rejected negative source information, their body investment decreased and body evaluation became more positive, illustrating the fluidity of body image. Women reciprocally influenced these sources (e.g., mentoring others to love their bodies, surrounding themselves with others who promote body acceptance, taking care of their health), which, in turn, promoted increased positive source information.

Zheng, Lijun; Zheng, Yong

2016-04-01

This study examined preferences for masculinity across faces, bodies, and personality traits in 462 homosexual and bisexual men in China. The impact of sexual self-labels (tops, bottoms, and versatiles) and attitude toward male masculinity on preferences for masculinity were also examined. Participants were asked to select the seven most desirable personality traits for a romantic partner from a list of 32 traits of gender roles. A series of 10 masculinized and feminized dimorphic images of male faces and bodies were then presented to participants, who were required to identify their preferred image. The results indicated that participants preferred more masculine faces, bodies, and personality traits. Significant differences in preferences for masculinity were found between tops, bottoms, and versatiles, with both bottoms and versatiles preferring more masculine faces, bodies, and personality traits than did tops. In addition, preferences for masculinity across faces, bodies, and traits showed a significant positive correlation with each other for all sexual self-labels, indicating a consistent preference for masculinity. Attitude toward male masculinity was significantly correlated with facial, body, and trait preferences; individuals with more rigid attitudes toward male masculinity (low acceptance of femininity in males) preferred more masculine characters. These results indicate a consistent preference for masculinity between both physical features (faces and bodies) and personality traits (instrumentality) that may be affected by observer perception.

The anatomic basis and articulatory features of speech production are often studied with imaging studies that are typically acquired in the supine body position. It is important to determine if changes in body orientation to the gravitational field alter vocal tract dimensions and speech acoustics. The purpose of this study was to assess the effect of body position (upright versus supine) on (1) oral and pharyngeal measurements derived from acoustic pharyngometry and (2) acoustic measurements of fundamental frequency (F0) and the first four formant frequencies (F1-F4) for the quadrilateral point vowels. Data were obtained for 27 male and female participants, aged 17 to 35 yrs. Acoustic pharyngometry showed a statistically significant effect of body position on volumetric measurements, with smaller values in the supine than upright position, but no changes in length measurements. Acoustic analyses of vowels showed significantly larger values in the supine than upright position for the variables of F0, F3, and the Euclidean distance from the centroid to each corner vowel in the F1-F2-F3 space. Changes in body position affected measurements of vocal tract volume but not length. Body position also affected the aforementioned acoustic variables, but the main vowel formants were preserved.

Objectives: The purpose of the investigation was to explore the body image disturbance of anorexics and in-vitro-fertilization patients (IvF-patients) with Body Grid and Body Identity Plot. Methods: The paper reports on an empirical study conducted with 32 anorexic patients and 30 IvF-patients. The structure of the body image was derived from the Body Grid, an idiographic approach following the Role Repertory Grid developed by George A. Kelly [17]. The representation of the body image and the degree of body-acceptance is represented graphically. Results: By the Body Grid and Body Identity Plot measures we were able to identify important differences in body image between anorexics and IvF-patients. Conclusion: The tendencies of dissociation in the body image of anorexics which we found must be seen in the sense of a specific body image disturbance which differs significantly from the body-experience profile of IvF-patients. With the grid approach it was possible to elicit the inner structure of body image and determine the acceptance of the body and integration of single body parts. PMID:19742059

Visual attention mediates the relationship between body satisfaction and susceptibility to the body size adaptation effect.

2018-01-01

Body size misperception-the belief that one is larger or smaller than reality-affects a large and growing segment of the population. Recently, studies have shown that exposure to extreme body stimuli results in a shift in the point of subjective normality, suggesting that visual adaptation may be a mechanism by which body size misperception occurs. Yet, despite being exposed to a similar set of bodies, some individuals within a given geographical area will develop body size misperception and others will not. The reason for these individual difference is currently unknown. One possible explanation stems from the observation that women with lower levels of body satisfaction have been found to pay more attention to images of thin bodies. However, while attention has been shown to enhance visual adaptation effects in low (e.g. rotational and linear motion) and high level stimuli (e.g., facial gender), it is not known whether this effect exists in visual adaptation to body size. Here, we test the hypothesis that there is an indirect effect of body satisfaction on the direction and magnitude of the body fat adaptation effect, mediated via visual attention (i.e., selectively attending to images of thin over fat bodies or vice versa). Significant mediation effects were found in both men and women, suggesting that observers' level of body satisfaction may influence selective visual attention to thin or fat bodies, which in turn influences the magnitude and direction of visual adaptation to body size. This may provide a potential mechanism by which some individuals develop body size misperception-a risk factor for eating disorders, compulsive exercise behaviour and steroid abuse-while others do not.

Significant mediation effects were found in both men and women, suggesting that observers’ level of body satisfaction may influence selective visual attention to thin or fat bodies, which in turn influences the magnitude and direction of visual adaptation to body size. This may provide a potential mechanism by which some individuals develop body size misperception–a risk factor for eating disorders, compulsive exercise behaviour and steroid abuse–while others do not.

Hyperphagia and obesity have been reported following damage to the hypothalamus in humans. Other brain sites are also postulated to be involved in the control of food intake and body weight regulation, such as the amygdala and brainstem. The brainstem, however, is thought to primarily integrate short-term meal-related signals but not affect long-term alterations in body weight, which is controlled by higher centers. The objective of this study was to identify structural pathways damaged in a patient with a brainstem cavernoma who experienced sudden onset of hyperphagia and >50 kg weight gain in <1 year following surgical drainage via a midline suboccipital craniotomy. Diffusion tensor imaging revealed loss of nerve fiber connections between her brainstem, hypothalamus and higher brain centers with preservation of motor tracks. Imaging and endocrine testing confirmed normal hypothalamic structure and function. Gastric bypass surgery restored normal appetite and body weight to baseline. This is the first report of 'brainstem obesity' and adds to the brain regions that can determine the long-term body weight set point in humans.

Visual information is a crucial aspect of medical knowledge. Building a comprehensive medical image base, in the spirit of the Unified Medical Language System (UMLS), would greatly benefit patient education and self-care. However, collection and annotation of such a large-scale image base is challenging. To combine visual object detection techniques with medical ontology to automatically mine web photos and retrieve a large number of disease manifestation images with minimal manual labeling effort. As a proof of concept, we first learnt five organ detectors on three detection scales for eyes, ears, lips, hands, and feet. Given a disease, we used information from the UMLS to select affected body parts, ran the pretrained organ detectors on web images, and combined the detection outputs to retrieve disease images. Compared with a supervised image retrieval approach that requires training images for every disease, our ontology-guided approach exploits shared visual information of body parts across diseases. In retrieving 2220 web images of 32 diseases, we reduced manual labeling effort to 15.6% while improving the average precision by 3.9% from 77.7% to 81.6%. For 40.6% of the diseases, we improved the precision by 10%. The results confirm the concept that the web is a feasible source for automatic disease image retrieval for health image database construction. Our approach requires a small amount of manual effort to collect complex disease images, and to annotate them by standard medical ontology terms.

In recent years, the demand for adult orthodontic treatment has grown rapidly; yet there is a paucity of information on this subgroup of patients. It is well known that understanding the psychological characteristics and motives of any patient is fundamental and that these factors might affect patient satisfaction and adherence with treatment. There is therefore a need for clinicians to improve their understanding of this subgroup to enhance the patient's experience of treatment delivery and to increase the potential for a successful treatment outcome. The aim of this study was to develop a measure for the assessment of motivating factors and psychological characteristics of adults seeking orthodontic treatment. This study involved the qualitative development of a valid patient-centered questionnaire to assess motivating factors for adults seeking orthodontic treatment. This was achieved through semi-structured in-depth interviews; key themes were identified and used to construct a questionnaire assessing motivation for treatment. This was then combined with 3 previously validated questionnaires to measure self-esteem, anxiety or depression, and body image and facial body image. The questionnaire was distributed to 172 adult orthodontic patients at different stages of treatment in a large teaching hospital in the United Kingdom. In addition, the self-esteem, body image, and facial body image scores were compared with data on orthognathic patients from the same hospital and with data from members of the general public. Desire to straighten the teeth and improve the smile were the key motivating factors for the adult group studied. Other motives included to improve the bite, improve facial appearance, and close (dental) spacing. With respect to the psychological characteristics of self-esteem, body image, and facial body image, the adult orthodontic group was comparable with the general public. However, differences were noted when comparing data from the adult orthodontic group with previously collected data on orthognathic patients. The motives for adults to seek orthodontic treatment are numerous and varied, whereas psychological traits appear to be closer to those of the general public than to orthognathic patients.

Peck, D; Pasciak, A

2014-06-15

Emphasis is often placed on minimizing radiation dose in diagnostic imaging without a complete consideration of the effect on image quality, especially those that affect diagnostic accuracy. This session will include a patient image-based review of diagnostic quantities important to radiologists in conventional radiography, including the effects of body habitus, age, positioning, and the clinical indication of the exam. The relationships between image quality, radiation dose, and radiation risk will be discussed, specifically addressing how these factors are affected by image protocols and acquisition parameters and techniques. This session will also discuss some of the actual and perceived radiation riskmore » associated with diagnostic imaging. Regardless if the probability for radiation-induced cancer is small, the fear associated with radiation persists. Also when a risk has a benefit to an individual or to society, the risk may be justified with respect to the benefit. But how do you convey the risks and the benefits to people? This requires knowledge of how people perceive risk and how to communicate the risk and the benefit to different populations. In this presentation the sources of errors in estimating risk from radiation and some methods used to convey risks are reviewed. Learning Objectives: Understand the image quality metrics that are clinically relevant to radiologists. Understand how acquisition parameters and techniques affect image quality and radiation dose in conventional radiology. Understand the uncertainties in estimates of radiation risk from imaging exams. Learn some methods for effectively communicating radiation risk to the public.« less

Infertility is a serious problem in a couple's life that affects their marriage relationships. So, dissatisfaction with sexual function resulting from interpersonal problems is common among these couples. This qualitative study aimed to explore the experiences of infertile women in their sexual life. This is a qualitative study with a phenomenological approach. The participants were 20 infertile women referring to the health care centers and infertility clinics of Isfahan and were selected through purposive sampling. Data were collected by tape recording of deep interviews and analyzed by Colaizzi's method. Analysis of the participants' experiences led to five main concepts: "Disturbed in femininity-body image," "discouragement of sexual relations," "sacrifice of sexual pleasure for the sake of getting pregnant," "confusion in sexual relation during infertility treatment," and "striving to protect their marriage." Findings revealed that infertility affects women's different aspects of sexual life, especially disturbance in femininity-body image and sexual reluctance. With regard to women's willingness to protect their matrimonial life and prevent sexual trauma as a destroying factor for their family's mental health, it seems sexual counseling is necessary for infertile couples.

It is of great importance to study the manifestations and the influencing factors of the time-related changes of infrared thermal images (ITI) of human body since the variable body surface temperature distribution seriously affected the application of ITI in medicine. In this paper, manifestations of time-related changes of the ITI of human body from three double-blind randomized trials and their correlation with meteorological factors (e.g. temperature, pressure, humidity, cold front passage and tropical cyclone landing) were studied. The trials were placebo or drug controlled studying the influences of Chinese medicine health food (including Shengsheng capsule with immunity adjustment function, Shengan capsule with sleep improvement function and Shengyi capsule with the function of helping to decrease serum lipid) on the ITI of human body. In the first thirty-six days of the trials images were scanned every six days and image data in the seven observation time spots (including the 0, 6, 12, 18, 24, 30, 36 day of the trial) were used for the time-related study. For every subject the scanned time was fixed in the day within two hours. The ITI features which could reflect the functions of the health foods were studied. The indexes of the features were relative magnitude (temperature difference between the viewing area and the reference area). Results showed that the variation tendencies of the trial group and control group were basically the same in placebo controlled trials and some of the long-term effects of Chinese medicine health food could be reflected significantly in certain time spots in the first thirty-six days. Time-related changes of the ITI of human body were closely related with meteorological factors but there were other influencing factors still need to be studied. As the ITI of human body could reflect the influences of Chinese medicine health foods and are closely related with meteorology, there are bright prospects for the application of ITI in health monitor.

Does the Supine Position Affect the Nasal Profile in Rhinoplasty Patients? A Comparison of Nasal Anthropometric Measurements in Different Body Positions.

Rhinoplasty surgeons are aware that the nasal profile differs according to body position, namely, the erect position in the consultation room vs the supine position on the operating table. It is not clear whether this difference is caused by an optical illusion or skin laxity due to positional change. To evaluate anthropometric measurements of the nose with different body positions and determine whether the supine position affects the nasal profile. In this retrospective study, 103 patients who underwent primary rhinoplasty were enrolled. Preoperatively, all patients underwent lateral cephalography in the erect position, and facial computed tomography (CT), in the supine position. We measured four nasal anthropometric parameters (the nasofrontal, nasolabial, and nasomental angles, and Simon's ratio) on lateral cephalograms and facial CT images, and compared these parameters between the two body positions. The nasofrontal angle was greater on facial CT than on cephalograms (P < 0.01). This difference was not related to age, sex, or body mass index (P > 0.05 each). We found no significant difference (P > 0.05) between the two positions in the nasolabial angle, nasomental angle, or Simon's ratio. The supine position does affect the nasal profile, especially in the radix area. Surgeons need to consider this difference in patients undergoing rhinoplasty. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc. Reprints and permission: journals.permissions@oup.com

Chronic skin diseases like eczema may lead to severe health and financial consequences for patients if not detected and controlled early. Early measurement of disease severity, combined with a recommendation for skin protection and use of appropriate medication can prevent the disease from worsening. Current diagnosis can be costly and time-consuming. In this paper, an automatic eczema detection and severity measurement model are presented using modern image processing and computer algorithm. The system can successfully detect regions of eczema and classify the identified region as mild or severe based on image color and texture feature. Then the model automatically measures skin parameters used in the most common assessment tool called "Eczema Area and Severity Index (EASI)," by computing eczema affected area score, eczema intensity score, and body region score of eczema allowing both patients and physicians to accurately assess the affected skin.

The aim of this study is to assess the influence of body image on consumers' willingness to pay (WTP) for potato chips carrying nutritional claims among obese and non-obese people. About 309 non-clinical individuals participated in a Real Choice Experiment. They were recruited by a company and grouped in: (i) non-obese with good body image; (ii) non-obese with body image dissatisfaction; (iii) obese with good body image; (iv) obese with body image dissatisfaction. Results indicate differences in consumers' willingness to pay among consumer groups. Body image dissatisfaction of normal people did not influence the WTP for healthier chips. Obese people with body image dissatisfaction were willing to pay more for healthier chips (i.e., low-salt content potato chips) than normal ones with body image dissatisfaction. Examining the role of knowledge in the light of how this could impact on body image is relevant to improve the health status of individuals and their diet. Knowledge about nutrition could improve the body image of obese people.

Psychosocial outcome measures, which attempt to examine acne from the patient's perspective, have become increasingly important in dermatology research. One such measure is the Body Image Disturbance Questionnaire. The authors' primary aim was to determine the validity and internal consistency of the Body Image Disturbance Questionnaire in patients with acne vulgaris. The secondary aim was to investigate the relationship between body image disturbance and quality of life. This cross-sectional investigation included 52 consecutive acne patients presenting to an outpatient dermatology clinic. Subjects completed the Body Image Disturbance Questionnaire, Skindex-16, and other body image and psychosocial functioning measures. An objective assessment of acne was performed. The Body Image Disturbance Questionnaire was internally consistent and converged with other known body image indices. Body Image Disturbance Questionnaire scores also correlated with Skindex-16 scores, confirming that quality of life and body image are related psychosocial constructs. The Body Image Disturbance Questionnaire appears to be an accurate instrument that can assess appearance-related concern and impairment in patients with acne vulgaris. Limitations include a small sample size and the cross-sectional design. PMID:21779418

Body image dissatisfaction is as well a risk factor for eating disorders (ED) and a central feature of ED. The exact nature of body image in adolescent ED is still debated. This study examined attitudinal body image in adolescent anorexia nervosa (AN) and bulimia nervosa (BN), and the association of age, maturational timing, duration of eating disorder, actual weight and general psychological distress with the attitudinal body image in ED. The study group consisted of an outpatient clinical sample of adolescents attending for assessment because of eating disorders. The attitudinal body image of 57 adolescents (girls) aged 14-21 years was studied at the beginning of the treatment. The attitudes to body shape, body size, appearance, tone and femininity were studied by a Likert format scale and by the body dissatisfaction (BD) and drive for thinness scales (DT) from EDI-2 inventory. Bulimics reported more body image dissatisfaction than anorectics. In multivariate analyses BN and higher general psychological distress had strong associations with body image dissatisfaction. Longer duration of ED and earlier menarche were also associated with negative body image. Attitudinal body image differs between adolescent AN and BN. The psychological distress has a great impact on body image in ED, which should be taken into account in assessment and in treatment interventions.

Cross-sectional. To examine the relationship between body image and leisure time physical activity (LTPA) among men with spinal cord injury (SCI). Specifically, to examine the moderating function of the perceived impact of body image on quality of life (QOL). Ontario, Canada. Men with SCI (N=50, 50% paraplegic) reported, (a) their functional and appearance body image (Adult Body Satisfaction Questionnaire), (b) their perceived impact of body image on QOL and (c) LTPA performed over the previous 3 days. Body image was in the 'normal' range compared with the general population. Linear regression analysis found a significant LTPA x body image impact on QOL interaction beta=0.39, P<0.05. Post hoc analysis showed that among individuals who reported a negative effect of body image on QOL, those who engaged in LTPA were less satisfied with their physical function than those who did not. For those who did not perceive their body image to negatively impact their QOL, there was generally no difference in functional body image between those who engaged in LTPA and those who did not. Appearance body image is not related to LTPA for men with SCI. It has been suggested that body dissatisfaction may motivate some individuals to engage in LTPA. However, for men living with SCI, functional body image may be associated with LTPA only when a negative effect on QOL is perceived. Future research should consider the moderating function of the perceived impact of body image on QOL when examining the relationship between LTPA and body image among men living with SCI.

Adolescent boys must cope with physical changes that hamper their ability to form a positive body image. Sociocultural messages influence the concepts of body image, personal appearance, and weight, encouraging men to develop lean and muscular bodies. The current study examined adolescent boys’ body image and its relationship to their subjective well-being (SWB) and the effect of the parent–adolescent relationship on body image and SWB. Participating in the research were 107 adolescent boys in Israel, aged 13 to 18 years. Four questionnaires were utilized: demographic, body mass index, Body Investment Scale, and Personal Well-Being Index. The findings indicate a significant, medium positive correlation between SWB and body image. After controlling for the variable of parent–adolescent relationship, the correlation weakened, indicating that the parent–adolescent relationship has no effect on adolescent boys’ SWB and body image. Body image was reported to be a predictor of SWB. PMID:28625112

ABSTRACT BACKGROUND Urogenital symptoms affect up to half of women after menopause, but their impact on women’s day-to-day functioning and wellbeing is poorly understood. METHODS Postmenopausal women aged 45 to 80 years reporting urogenital dryness, soreness, itching, or pain during sex were recruited to participate in in-depth focus groups to discuss the impact of their symptoms. Focus groups were homogenous with respect to race/ethnicity and stratified by age (for White or Black women) or language (for Latina women). Transcripts of sessions were analyzed according to grounded theory. RESULTS Six focus groups were conducted, involving 44 women (16 White, 14 Black, 14 Latina). Five domains of functioning and wellbeing affected by symptoms were identified: sexual functioning, everyday activities, emotional wellbeing, body image, and interpersonal relations. For some participants, symptoms primarily affected their ability to have and enjoy sex, as well as be responsive to their partners. For others, symptoms interfered with everyday activities, such as exercising, toileting, or sleeping. Participants regarded their symptoms as a sign that they were getting old or their body was deteriorating; women also associated symptoms with a loss of womanhood or sexuality. Additionally, participants reported feeling depressed, embarrassed, and frustrated about their symptoms, and expressed reluctance to discuss them with friends, family, or health care providers. CONCLUSIONS Urogenital symptoms can have a marked impact on sexual functioning, everyday activities, emotional wellbeing, body image, and interpersonal relations after menopause. Clinicians may need to question women actively about these symptoms, as many are reluctant to seek help for this problem. PMID:19908103

This study sought to explore parental perceptions of body image in preschoolers. We conducted semi-structured interviews with 30 primary caregivers of preschoolers to examine knowledge, beliefs, and strategies regarding early body image socialization in families. Thematic Analysis yielded three themes highlighting knowledge gaps, belief discrepancies, and limited awareness of strategies. Findings regarding knowledge: Most participants defined body image as objective attractiveness rather than subjective self-assessment (53%) and focused on negative body image. Beliefs: Although 97% of participants believed weight and shape impact children's self-esteem, 63% believed preschoolers too young to have a body image. Strategies: Most participants (53%) said family was a primary influence on body image, but identified few effective strategies and 63% said they did not do anything to influence children's body image. Findings suggested family body image socialization in preschoolers is occurring outside the awareness of parents and the concept of positive body image is underdeveloped.

Subliminal presentation of emotionally negative vs positive primes increases the perceived beauty of target stimuli.

PubMed

Era, Vanessa; Candidi, Matteo; Aglioti, Salvatore Maria

2015-11-01

Emotions have a profound influence on aesthetic experiences. Studies using affective priming procedures demonstrate, for example, that inducing a conscious negative emotional state biases the perception of abstract stimuli towards the sublime (Eskine et al. Emotion 12:1071-1074, 2012. doi: 10.1037/a0027200). Moreover, subliminal happy facial expressions have a positive impact on the aesthetic evaluation of abstract art (Flexas et al. PLoS ONE 8:e80154, 2013). Little is known about how emotion influences aesthetic perception of non-abstract, representational stimuli, especially those that are particularly relevant for social behaviour, like human bodies. Here, we explore whether the subliminal presentation of emotionally charged visual primes modulates the explicit subjective aesthetic judgment of body images. Using a forward/backward masking procedure, we presented subliminally positive and negative, arousal-matched, emotional or neutral primes and measured their effect on the explicit evaluation of perceived beauty (high vs low) and emotion (positive vs negative) evoked by abstract and body images. We found that negative primes increased subjective aesthetic evaluations of target bodies or abstract images in comparison with positive primes. No influence of primes on the emotional dimension of the targets was found, thus ruling out an unspecific arousal effect and strengthening the link between emotional valence and aesthetic appreciation. More specifically, that subliminal negative primes increase beauty ratings compared to subliminal positive primes indicates a clear link between negative emotions and positive aesthetic evaluations and vice versa, suggesting a possible link between negative emotion and the experience of sublime in art. The study expands previous research by showing the effect of subliminal negative emotions on the subjective aesthetic evaluation not only of abstract but also of body images.

Adolescence is a peculiar age mainly characterized by physical and psychological changes that may affect the perception of one's own and others' body. This perceptual peculiarity may influence the way in which bottom-up and top-down processes interact and, consequently, the perception and evaluation of art. This study is aimed at investigating, by means of the eye-tracking technique, the visual explorative behavior of adolescents while looking at paintings. Sixteen color paintings, categorized as dynamic and static, were presented to twenty adolescents; half of the images represented natural environments and half human individuals; all stimuli were displayed under aesthetic and movement judgment tasks. Participants' ratings revealed that, generally, nature images are explicitly evaluated as more appealing than human images. Eye movement data, on the other hand, showed that the human body exerts a strong power in orienting and attracting visual attention and that, in adolescence, it plays a fundamental role during aesthetic experience. In particular, adolescents seem to approach human-content images by giving priority to elements calling forth movement and action, supporting the embodiment theory of aesthetic perception.

In this study, we conducted a content analysis of 243 photographic images of men published on the gay male-oriented blog Queerty.com. We also analyzed 435 user-generated comments from a randomly selected 1-year sample. Focusing on images' body types, we found that the range of body types featured on the blog was quite narrow-the vast majority of images had very low levels of body fat and very high levels of muscularity. Users' body image-related comments typically endorsed and celebrated images; critiques of images were comparatively rare. Perspectives from objectification theory and social comparison theory suggest that the images and commentary found on the blog likely reinforce unhealthy body image in gay male communities.

Breast cancer patients experience a variety of altered appearance--such as loss or disfigurement of breasts, discolored skin, and hair loss--which result in psychological distress that affect their quality of life. This study aims to evaluate the impact of socioeconomic status on the altered appearance distress, body image, and quality of life among Korean breast cancer patients. A cross-sectional survey was conducted at advocacy events held at 16 different hospitals in Korea. Subjects were eligible to participate if they were 18 years of age or older, had a histologically confirmed diagnosis of breast cancer, had no evidence of recurrence or metastasis, and had no psychological problems at the time of the survey. Employment status, marital status, education, and income were assessed for patient socioeconomic status. Altered appearance distress was measured using the NCI's cancer treatment side effects scale; body image and quality of life were measured by the EORTC QLC-C30 and BR23. Means and standard deviations of each outcome were compared by socioeconomic status and multivariate linear regression models for evaluating the association between socioeconomic status and altered appearance distress, body image, and quality of life. A total of 126 breast cancer patients participated in the study; the mean age of participants was 47.7 (SD=8.4). Of the total, 83.2% were married, 85.6% received more than high school education, 35.2% were employed, and 41% had more than $3000 in monthly household income. About 46% had mastectomy, and over 30% were receiving either chemotherapy or radiation therapy at the time of the survey. With fully adjusted models, the employed patients had significantly higher altered appearance distress (1.80 vs 1.48; p<0.05) and poorer body image (36.63 vs 51.69; p<0.05) compared to the patients who were unemployed. Higher education (10.58, standard error (SE)=7.63) and family income (12.88, SE=5.08) was positively associated with better body image after adjusting for age, disease stage at diagnosis, current treatment status, and breast surgery type. Similarly, patients who were married and who had higher education had better quality of life were statistically significant in the multivariate models. Socioeconomic status is significantly associated with altered appearance distress, body image, and quality of life in Korean women with breast cancer. Patients who suffer from altered appearance distress or lower body image are much more likely to experience psychosocial, physical, and functional problems than women who do not, therefore health care providers should be aware of the changes and distresses that these breast cancer patients go through and provide specific information and psychosocial support to socioeconomically more vulnerable patients.

Although the importance of bifunctional chelators (BFCs) is well recognized, the chemophysical parameters of chelators that govern the biological behavior of the corresponding bioconjugates have not been clearly elucidated. Here, five BFCs closely related in structure were conjugated with a cyclic RGD peptide and radiolabeled with Cu-64 ions. Various biophysical and chemical properties of the Cu(II) complexes were analyzed with the aim of identifying correlations between individual factors and the biological behavior of the conjugates. Tumor uptake and body clearance of the 64 Cu-labeled bioconjugates were directly compared by animal PET imaging in animal models, which was further supported by biodistribution studies. Conjugates containing propylene cross-bridged chelators showed higher tumor uptake, while a closely related ethylene cross-bridged analogue exhibited rapid body clearance. High in vivo stability of the copper-chelator complex was strongly correlated with high tumor uptake, while the overall lipophilicity of the bioconjugate affected both tumor uptake and body clearance.

The present study aimed to investigate the effect of (18)F-fluorodeoxyglucose (FDG) extravasation on the time taken for tumoral uptake to reach a plateau. For the animal experiment, FDG extravasation was conducted in the tails of HCT116 tumor-bearing xenograft mice models in three groups (no extravasation, 40 % extravasation, and 80 % extravasation; n = 5, each). Dynamic positron emission tomography (PET) images were acquired over a period of 2 h following injection. Time-activity curves for FDG in the tails and tumors were calculated. For the clinical experiment, 22 patients (male:female, 14:8; age range, 70.8 ± 9.2 years) were subjected to PET/computed tomography (PET/CT) 1 h after the injection of FDG. The inclusion criteria were as follows: (1) submitted to both whole-body and subsequent regional scanning; (2) entire extravasation activity visualized in the whole-body images; (3) tumor visualized on both whole-body and additional regional images; and (4) status of tumor either confirmed by biopsy or clinically suspected for malignancy. The standardized uptake values (SUVs) of the tumors (on the whole-body and additional PET images) and extravasation sites were recorded. There were no significant differences in the time taken for tumoral uptake to reach a plateau and that to reach minimum activity at the extravasation site among the three groups of mice. However, the mean tumoral activity and activity at the extravasation site were negatively correlated at 1 h post-injection. According to the clinical PET findings, the differences in SUV between the whole-body and regional images were not significantly correlated with the interval between injection of FDG and start of whole-body scanning, interval between the start of whole-body scanning and start of regional scanning, extravasation volume, maximum SUV of the extravasation site, or total activity at the extravasation site. The time taken for tumoral uptake to reach a plateau is not affected by extravasation, even at extensive degrees. Thus, in routine practice, the imaging time of approximately 60 min post-injection need not be modified even if extravasation is identified. However, tumor SUV may be underestimated in cases of extravasation.

Human lumbar vertebrae support the weight of the upper body. Loads lifted and carried by the upper extremities cause significant loading stress to the vertebral bodies. It is well established that trauma-induced vertebral fractures are common especially among elderly people. The aim of this study was to investigate the morphological factors that could have affected the prevalence of trauma-related vertebral fractures from medieval times to the present day. To determine if morphological differences existed in the size and shape of the vertebral body between medieval times and the present day, the vertebral body size and shape was measured from the 4th lumbar vertebra using magnetic resonance imaging (MRI) and standard osteometric calipers. The modern samples consisted of modern Finns and the medieval samples were from archaeological collections in Sweden and Britain. The results show that the shape and size of the 4th lumbar vertebra has changed significantly from medieval times in a way that markedly affects the biomechanical characteristics of the lumbar vertebral column. These changes may have influenced the incidence of trauma- induced spinal fractures in modern populations. PMID:19279681

Poor body image is common among individuals seeking bariatric surgery and is associated with adverse psychosocial sequelae. Following massive weight loss secondary to bariatric surgery, many individuals experience excess skin and associated concerns, leading to subsequent body contouring procedures. Little is known, however, about body image changes and associated features from pre-to post-bariatric surgery and subsequent body contouring. The objective of the present study was to conduct a comprehensive literature review of body image following bariatric surgery to help inform future clinical research and care. The articles for the current review were identified by searching PubMed and SCOPUS and references from relevant articles. A total of 60 articles examining body image post-bariatric surgery were identified, and 45 did not include body contouring surgery. Overall, there was great variation in standards of reporting sample characteristics and body image terms. When examining broad levels of body image dissatisfaction, the literature suggests general improvements in certain aspects of body image following bariatric surgery; however, few studies have systematically examined various body image domains from pre-to post-bariatric surgery and subsequent body contouring surgery. In conclusion, there is a paucity of research that examines the multidimensional elements of body image following bariatric surgery. © 2018 World Obesity Federation.

Time-series animation techniques for visualizing urban growth

USGS Publications Warehouse

Acevedo, W.; Masuoka, P.

1997-01-01

Time-series animation is a visually intuitive way to display urban growth. Animations of landuse change for the Baltimore-Washington region were generated by showing a series of images one after the other in sequential order. Before creating an animation, various issues which will affect the appearance of the animation should be considered, including the number of original data frames to use, the optimal animation display speed, the number of intermediate frames to create between the known frames, and the output media on which the animations will be displayed. To create new frames between the known years of data, the change in each theme (i.e. urban development, water bodies, transportation routes) must be characterized and an algorithm developed to create the in-between frames. Example time-series animations were created using a temporal GIS database of the Baltimore-Washington area. Creating the animations involved generating raster images of the urban development, water bodies, and principal transportation routes; overlaying the raster images on a background image; and importing the frames to a movie file. Three-dimensional perspective animations were created by draping each image over digital elevation data prior to importing the frames to a movie file. ?? 1997 Elsevier Science Ltd.

Automatic exposure control in CT: the effect of patient size, anatomical region and prescribed modulation strength on tube current and image quality.

To study the effect of patient size, body region and modulation strength on tube current and image quality on CT examinations that use automatic tube current modulation (ATCM). Ten physical anthropomorphic phantoms that simulate an individual as neonate, 1-, 5-, 10-year-old and adult at various body habitus were employed. CT acquisition of head, neck, thorax and abdomen/pelvis was performed with ATCM activated at weak, average and strong modulation strength. The mean modulated mAs (mAsmod) values were recorded. Image noise was measured at selected anatomical sites. The mAsmod recorded for neonate compared to 10-year-old increased by 30 %, 14 %, 6 % and 53 % for head, neck, thorax and abdomen/pelvis, respectively, (P < 0.05). The mAsmod was lower than the preselected mAs with the exception of the 10-year-old phantom. In paediatric and adult phantoms, the mAsmod ranged from 44 and 53 for weak to 117 and 93 for strong modulation strength, respectively. At the same exposure parameters image noise increased with body size (P < 0.05). The ATCM system studied here may affect dose differently for different patient habitus. Dose may decrease for overweight adults but increase for children older than 5 years old. Care should be taken when implementing ATCM protocols to ensure that image quality is maintained. • ATCM efficiency is related to the size of the patient's body. • ATCM should be activated without caution in overweight adult individuals. • ATCM may increase radiation dose in children older than 5 years old. • ATCM efficiency depends on the protocol selected for a specific anatomical region. • Modulation strength may be appropriately tuned to enhance ATCM efficiency.

Static and dynamic body image in bulimia nervosa: mental representation of body dimensions and biological motion patterns.

Vocks, Silja; Legenbauer, Tanja; Rüddel, Heinz; Troje, Nikolaus F

2007-01-01

The aim of the present study was to find out whether in bulimia nervosa the perceptual component of a disturbed body image is restricted to the overestimation of one's own body dimensions (static body image) or can be extended to a misperception of one's own motion patterns (dynamic body image). Participants with bulimia nervosa (n = 30) and normal controls (n = 55) estimated their body dimensions by means of a photo distortion technique and their walking patterns using a biological motion distortion device. Not only did participants with bulimia nervosa overestimate their own body dimensions, but also they perceived their own motion patterns corresponding to a higher BMI than did controls. Static body image was correlated with shape/weight concerns and drive for thinness, whereas dynamic body image was associated with social insecurity and body image avoidance. In bulimia nervosa, body image disturbances can be extended to a dynamic component. (c) 2006 by Wiley Periodicals, Inc.

What is and what is not positive body image? Conceptual foundations and construct definition.

2015-06-01

A decade ago, research on positive body image as a unique construct was relatively nonexistent, and now this area is flourishing. How and why did positive body image scholarship emerge? What is known about this contemporary construct? This article situates and contextualizes positive body image within Cash's scholarship, eating disorder prevention efforts, feminist influences, strength-based disciplines within psychology, and Buddhism. Extracting insights from quantitative and qualitative research, this article demonstrates that positive body image is (a) distinct from negative body image; (b) multifaceted (including body appreciation, body acceptance/love, conceptualizing beauty broadly, adaptive investment in appearance, inner positivity, interpreting information in a body-protective manner); (c) holistic; (d) stable and malleable; (e) protective; (f) linked to self-perceived body acceptance by others; and (g) shaped by social identities. Complementing what positive body image is, this article further details what positive body image is not to provide a more nuanced understanding of this construct. Copyright © 2015 Elsevier Ltd.

2015-06-01

The emergence of positive body image research during the last 10 years represents an important shift in the body image literature. The existing evidence provides a strong empirical basis for the study of positive body image and research has begun to address issues of age, gender, ethnicity, culture, development, and intervention in relation to positive body image. This article briefly reviews the existing evidence before outlining directions for future research. Specifically, six areas for future positive body image research are outlined: (a) conceptualization, (b) models, (c) developmental factors, (d) social interactions, (e) cognitive processing style, and (f) interventions. Finally, the potential role of positive body image as a protective factor within the broader body image literature is discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Body image distress is well-documented in patients with cancer, but little is known about the course of body image distress over time and the role of psychosocial resources such as hope. This prospective study sought to explore the dynamics between trajectories of body image distress and hope across time. Cancer patients receiving outpatient treatment at a cancer center completed self-reported measures of body image distress (Body Image Scale) and hope (Adult Hope Scale) at baseline (within three months of their cancer diagnosis) and follow-up (six months post-baseline; N = 111). Trajectories of intra-individual change (improved, stable, and declined) for body image distress were calculated based on the minimal clinically important difference (±0.5 baseline SD). There was a significant increase in body image distress at follow-up (p < .05); hope remained stable. Rank-transformed mixed-factor repeated measures analyses of variance revealed significant interactions between body image distress trajectory groups and time on hope, suggesting that patients experiencing improvements in body image distress reported higher levels of hope than those who had stable or deteriorating levels of body image distress F(2,108) = 3.25, p < .05. The findings of this exploratory study suggest that psychosocial resources like hope may also reduce body image distress across time in a sample of cancer patients, although the mechanisms of interaction require further examination. Supportive care could lend greater focus to improving patients' hope to alleviating body image distress.

Assessment of perception and intention in pesticide purchase in Taiwan.

Environmental chemical agents such as pesticides can be purchased easily at a relatively low price, and this has resulted in high concern of environmental toxicity to human health, due to their persistence in various environmental bodies. Hence, this study aims to propose important factors influencing pesticide purchase intentions, including consumers' perceptions of the brand image and the ecological health risk. Since consumers are primary users, the seller knows the product's features but not the psychology of those who purchase it. Therefore, we attempted to clarify purchase intentions and perceptions using structural equation modeling techniques to empirically analyze survey data from 324 pesticide consumers in Taiwan. Our results demonstrate that perceived brand image positively affects perceived quality of a product, whereas perceived risk negatively affects perceived quality and purchase intentions. Furthermore, this study provides evidence that perceived quality positively affects purchase intentions. These relationships suggest that perceived quality mediates both the positive association between brand image and purchase intentions and the negative association between perceived risk and purchase intentions. Based on such outcomes, we propose that consumers need to be informed of pesticides related to costs and environmental benefits.

Motion illusions in optical art presented for long durations are temporally distorted.

Static figurative images implying human body movements observed for shorter and longer durations affect the perception of time. This study examined whether images of static geometric shapes would affect the perception of time. Undergraduate participants observed two Optical Art paintings by Bridget Riley for 9 or 36 s (group G9 and G36, respectively). Paintings implying different intensities of movement (2.0 and 6.0 point stimuli) were randomly presented. The prospective paradigm in the reproduction method was used to record time estimations. Data analysis did not show time distortions in the G9 group. In the G36 group the paintings were differently perceived: that for the 2.0 point one are estimated to be shorter than that for the 6.0 point one. Also for G36, the 2.0 point painting was underestimated in comparison with the actual time of exposure. Motion illusions in static images affected time estimation according to the attention given to the complexity of movement by the observer, probably leading to changes in the storage velocity of internal clock pulses.

Little is known about how fathers of patients with eating disorders perceive their own body. In this study we investigated body image perception of patients with anorexia and bulimia nervosa and body image perception of their fathers in a computer assisted approach. A computer program, the somatomorphic matrix, is presented that allows modeling of perceived and desired body-images of patients and their relatives. Patients and fathers rated their own body images and fathers additionally rated the body images of their daughters. The images implemented in the program correspond with defined percentages of body fat and muscularity. Selected images were compared with subjects' anthropometric data regarding body fat and muscularity. Data from 42 father-daughter-dyads (27 patients with anorexia, 15 with bulimia nervosa) were examined. Differences between both diagnostic groups were compared and associations between fathers' and daughters' body image perceptions within each group were investigated. Patients with anorexia nervosa overestimated their bodies on the body fat dimension. Patients with bulimia nervosa wished to have a body with less fat. Fathers of both groups of patients perceived their own bodies correctly but wished to have less body fat and to be more muscular. The wish for a change in body fat of anorexia nervosa patients was highly correlated with fathers' BMI (r=0.49; p=0.009). The wish for a change in body fat of bulimia nervosa patients was correlated with fathers' distorted body image perception in terms of muscularity (r=-0.66, p=0.007) and with fathers' wish for a more muscular body (r=-0.51, p=0.05). Body images of patients with eating disorders and their fathers are related in the group of patients with bulimia nervosa. Perhaps, body images of fathers should be addressed in family therapy with patients with bulimia nervosa.

To determine whether differences in hydration state, which could arise from routine clinical procedures such as overnight fasting, affect brain total water content (TWC) and brain volume measured with magnetic resonance imaging (MRI). Twenty healthy volunteers were scanned with a 3T MR scanner four times: day 1, baseline scan; day 2, hydrated scan after consuming 3L of water over 12 hours; day 3, dehydrated scan after overnight fasting of 9 hours, followed by another scan 1 hour later for reproducibility. The following MRI data were collected: T2 relaxation (for TWC measurement), inversion recovery (for T1 measurement), and 3D T1 -weighted (for brain volumes). Body weight and urine specific gravity were also measured. TWC was calculated by fitting the T2 relaxation data with a nonnegative least-squares algorithm, with corrections for T1 relaxation and image signal inhomogeneity and normalization to ventricular cerebrospinal fluid. Brain volume changes were measured using SIENA. TWC means were calculated within 14 tissue regions. Despite indications of dehydration as demonstrated by increases in urine specific gravity (P = 0.03) and decreases in body weight (P = 0.001) between hydrated and dehydrated scans, there was no measurable change in TWC (within any brain region) or brain volume between hydration states. We demonstrate that within a range of physiologic conditions commonly encountered in routine clinical scans (no pretreatment with hydration, well hydrated before MRI, and overnight fasting), brain TWC and brain volumes are not substantially affected in a healthy control cohort.

Brown, Zoe; Tiggemann, Marika

2016-12-01

A large body of research has documented that exposure to images of thin fashion models contributes to women's body dissatisfaction. The present study aimed to experimentally investigate the impact of attractive celebrity and peer images on women's body image. Participants were 138 female undergraduate students who were randomly assigned to view either a set of celebrity images, a set of equally attractive unknown peer images, or a control set of travel images. All images were sourced from public Instagram profiles. Results showed that exposure to celebrity and peer images increased negative mood and body dissatisfaction relative to travel images, with no significant difference between celebrity and peer images. This effect was mediated by state appearance comparison. In addition, celebrity worship moderated an increased effect of celebrity images on body dissatisfaction. It was concluded that exposure to attractive celebrity and peer images can be detrimental to women's body image. Copyright © 2016 Elsevier Ltd. All rights reserved.

Can community consciousness be a bad thing? A moderated mediation analysis of heterosexism, mental health, and body appreciation in sexual minority men

Simpson, Courtney C.; Sutter, Megan; Perrin, Paul B.

2016-01-01

This study examined the connections among heterosexism, mental health, body appreciation, and community consciousness in sexual minority men. Participants (N = 89) completed a national online survey. Simultaneous multiple regression found that heterosexism explained 9.4% of the variance in body appreciation and 25.8% of the variance in mental health; mental health accounted for 28.0% of the variance in body appreciation. Within these models, harassment/rejection heterosexism was a unique positive predictor of mental health and a unique negative predictor of body appreciation; depression was a unique negative predictor of body appreciation. A moderated mediational model found that depression mediated the relationship between harassment/rejection heterosexism and body appreciation, but only in men who endorsed high community consciousness. Intervention research might benefit from helping sexual minority men explore the ways in which body image is affected by heterosexism and mental health, as well as the ways that contemporary Western gay communities might contribute to these connections.

Patients with eating disorders tend to experience low levels of body esteem. To assess the psychosocial processes that may predict low body esteem in these individuals, we assessed the structural interrelations among attachment anxiety, attachment avoidance, alexithymia, and body esteem in a cross-sectional sample of patients with eating disorders. We tested a model in which alexithymia mediates the relationship between attachment insecurity and body esteem. Participants were 300 women with anorexia nervosa (n = 109), bulimia nervosa (n = 130), and eating disorders not otherwise specified (n = 61) who completed pretreatment self-report questionnaires at intake for a day hospital treatment program. We found a direct and negative relationship between attachment anxiety and body esteem. Additionally, attachment avoidance had an indirect negative relationship to body esteem through alexithymia. These results indicate that therapists may attend to attachment insecurity and affective regulation strategies when addressing body image issues in patients with eating disorders. © 2013 Elsevier Ltd.

The purpose of this study was to develop a simple and inexpensive system for controlling body temperature in small animal experiments using magnetic resonance imaging (MRI) and to investigate the effect of body temperature on the kinetic behavior of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) in the liver. In our temperature-control system, body temperature was controlled using a feedback-regulated heated or cooled air flow generated by two Futon dryers. The switches of the two Futon dryers were controlled using a digital temperature controller, in which the rectal temperature of a mouse measured by an optical fiber thermometer was used as the input. In experimental studies, male ICR mice aged 8weeks old were used and allocated into 5 groups (39-, 36-, 33-, 30-, and 27-degree groups, n=10), in which the body temperature was maintained at 39 °C, 36 °C, 33 °C, 30 °C, and 27 °C, respectively, using our system. The dynamic contrast-enhanced MRI (DCE-MRI) data were acquired with an MRI system for animal experiments equipped with a 1.5-Tesla permanent magnet, for approximately 43min, after the injection of Gd-EOB-DTPA into the tail vein. After correction of the image shift due to the temperature-dependent drift of the Larmor frequency using the gradient-based image registration method with robust estimation of displacement parameters, the kinetic behavior of Gd-EOB-DTPA was analyzed using an empirical mathematical model. With the use of this approach, the upper limit of the relative enhancement (A), the rates of contrast uptake (α) and washout (β), the parameter related to the slope of early uptake (q), the area under the curve (AUC), the maximum relative enhancement (REmax), the time to REmax (Tmax), and the elimination half-life of the contrast agent (T1/2) were calculated. The body temperature of mice could be controlled well by use of our system. Although there were no significant differences in α, AUC, and q among groups, there were significant differences in A, REmax, β, Tmax, and T1/2, indicating that body temperature significantly affects the kinetic behavior of Gd-EOB-DTPA in the liver. In conclusion, our system will be useful for controlling body temperature in small animal experiments using MRI. Because body temperature significantly affects the kinetic behavior of Gd-EOB-DTPA in the liver, the control of body temperature is essential and should be carefully considered when performing DCE-MRI studies in small animal experiments. © 2013.

Body Image and Body Contouring Procedures.

PubMed

Sarwer, David B; Polonsky, Heather M

2016-10-01

Dissatisfaction with physical appearance and body image is a common psychological phenomena in Western society. Body image dissatisfaction is frequently reported by those who have excess body weight, but also is seen in those of normal body weight. For both groups of individuals, this dissatisfaction impacts self-esteem and quality of life. Furthermore, it is believed to be the motivational catalyst to a range of appearance-enhancing behaviors, including weight loss efforts and physical activity. Body image dissatisfaction is also believed to play a role in the decision to seek the wide range of body contouring procedures offered by aesthetic physicians. Individuals who seek these procedures typically report increased body image dissatisfaction, focus on the feature they wish to alter with treatment, and often experience improvement in body image following treatment. At the same time, extreme body image dissatisfaction is a symptom of a number of recognized psychiatric disorders. These include anorexia nervosa, bulimia nervosa, and body dysmorphic disorder (BDD), all of which can contraindicate aesthetic treatment. This special topic review paper provides an overview of the relationship between body image dissatisfaction and aesthetic procedures designed to improve body contouring. The review specifically focuses on the relationship of body image and body weight, as well as the presentation of body image psychopathology that would contraindicate aesthetic surgery. The overall goal of the paper is to highlight the clinical implications of the existing research and provide suggestions for future research on the psychological aspects of body contouring procedures. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Conventional processes for prosthetic socket fabrication are heavily subjective, often resulting in an interface to the human body that is neither comfortable nor completely functional. With nearly 100% of amputees reporting that they experience discomfort with the wearing of their prosthetic limb, designing an effective interface to the body can significantly affect quality of life and future health outcomes. Active research in medical imaging and biomechanical tissue modeling of residual limbs has led to significant advances in computer aided prosthetic socket design, demonstrating an interest in moving toward more quantifiable processes that are still patient-specific. In our work, medical ultrasonography is being pursued to acquire data that may quantify and improve the design process and fabrication of prosthetic sockets while greatly reducing cost compared to an MRI-based framework. This paper presents a prototype limb imaging system that uses a medical ultrasound probe, mounted to a mechanical positioning system and submerged in a water bath. The limb imaging is combined with three-dimensional optical imaging for motion compensation. Images are collected circumferentially around the limb and combined into cross-sectional axial image slices, resulting in a compound image that shows tissue distributions and anatomical boundaries similar to magnetic resonance imaging. In this paper we provide a progress update on our system development, along with preliminary results as we move toward full volumetric imaging of residual limbs for prosthetic socket design. This demonstrates a novel multi-modal approach to residual limb imaging.

This systematic review identifies studies of body image and perinatal depression with the goal of elucidating the complex role that body image plays in prenatal and postpartum depression, improving measurement, and informing next steps in research. We conducted a literature search of the PubMed database (1996-2014) for English language studies of (1) depression, (2) body image, and (3) pregnancy or postpartum. In total, 19 studies matched these criteria. Cross-sectional studies consistently found a positive association between body image dissatisfaction and perinatal depression. Prospective cohort studies found that body image dissatisfaction predicted incident prenatal and postpartum depression; findings were consistent across different aspects of body image and various pregnancy and postpartum time periods. Prospective studies that examined the reverse association found that depression influenced the onset of some aspects of body image dissatisfaction during pregnancy, but few evaluated the postpartum onset of body image dissatisfaction. The majority of studies found that body image dissatisfaction is consistently but weakly associated with the onset of prenatal and postpartum depression. Findings were less consistent for the association between perinatal depression and subsequent body image dissatisfaction. While published studies provide a foundation for understanding these issues, methodologically rigorous studies that capture the perinatal variation in depression and body image via instruments validated in pregnant women, consistently adjust for important confounders, and include ethnically diverse populations will further elucidate this association.

Objectives Pediatric obesity is complicated by many factors including psychological issues, such as body dissatisfaction. Body image assessment tools are used with children to measure their acceptance of their body shape or image. Limited research has been conducted with African American and American Indian children to understand their opinions on assessment tools created. This study investigated: (a) children's perception about body image and (b) differences between two body image instruments among low-income, multi-ethnic children. Methods This study uses mixed methodology including focus groups (qualitative) and body image assessment instruments (quantitative). Fifty-one children participated (25 girls, 26 boys); 53% of children identified as African American and 47% as American Indian. The average age was 10.4 years. Open coding methods were used by identify themes from focus group data. SPSS was used for quantitative analysis. Results Children preferred the Figure Rating Scale (FRS/silhouette) instrument over the Children's Body Image Scale (CBIS/photo) because their body parts and facial features were more detailed. Children formed their body image perception with influence from their parents and the media. Children verbalized that they have experienced negative consequences related to poor body image including disordered eating habits, depression, and bullying. Healthy weight children are also aware of weight-related bullying that obese and overweight children face. Conclusions for Practice Children prefer that the images on a body image assessment tool have detailed facial features and are clothed. Further research into body image assessment tools for use with African American and American Indian children is needed.

Large-bodied, top- and apex predators (e.g., crocodilians, sharks, wolves, killer whales) can exert strong top-down effects within ecological communities through their interactions with prey. Due to inherent difficulties while studying the behavior of these often dangerous predatory species, relatively little is known regarding their feeding behaviors and activity patterns, information that is essential to understanding their role in regulating food web dynamics and ecological processes. Here we use animal-borne imaging systems (Crittercam) to study the foraging behavior and activity patterns of a cryptic, large-bodied predator, the American alligator (Alligator mississippiensis) in two estuaries of coastal Florida, USA. Using retrieved video data we examine the variation in foraging behaviors and activity patterns due to abiotic factors. We found the frequency of prey-attacks (mean = 0.49 prey attacks/hour) as well as the probability of prey-capture success (mean = 0.52 per attack) were significantly affected by time of day. Alligators attempted to capture prey most frequently during the night. Probability of prey-capture success per attack was highest during morning hours and sequentially lower during day, night, and sunset, respectively. Position in the water column also significantly affected prey-capture success, as individuals’ experienced two-fold greater success when attacking prey while submerged. These estimates are the first for wild adult American alligators and one of the few examples for any crocodilian species worldwide. More broadly, these results reveal that our understandings of crocodilian foraging behaviors are biased due to previous studies containing limited observations of cryptic and nocturnal foraging interactions. Our results can be used to inform greater understanding regarding the top-down effects of American alligators in estuarine food webs. Additionally, our results highlight the importance and power of using animal-borne imaging when studying the behavior of elusive large-bodied, apex predators, as it provides critical insights into their trophic and behavioral interactions.

The main purpose of this study was to analyze the current psychosocial implications of malocclusion in Ibadan, Nigeria. The study sample comprised 614 secondary school children (327 males and 287 females) aged 12-18 years (mean age, 14.9 +/- 2.9 SD) who filled in a questionnaire containing general questions about body image and specific inquires concerning self-perception and social implications of dental appearance. The children's occlusions were also assessed using the Dental Aesthetic Index (DAI) and the malocclusion traits related to body image, self-perception, and social implications of dental appearance. Subjects with malocclusion rated only the teeth significantly least satisfactory among other twelve items of body image. The lowest rating was observed in subjects with crowding of the maxillary and mandibular incisor segments. Highly significant differences (P < 0.001) were found between subjects with normal or minor malocclusion and those with marked malocclusion in indicating awareness of malocclusion, dissatisfaction with the appearance of the teeth, and unfavourable appearance of the teeth compared with those of peers. Schoolmates' teasing occurred significantly more often in the presence of malocclusion (P < 0.001). Unfavourable perceptions of the teeth were expressed significantly more often by subjects with anterior maxillary irregularities of up to 1 mm and more, spacing of both maxillary and mandibular incisor segments, midline diastema, crowding (especially of the mandibular incisor segment), anterior open bite and molar relation deviations. It was concluded that certain malocclusions, especially occlusal and space anomalies, may adversely affect body image and self-concept of Nigerian adolescents.

2008-01-01

The present study was conducted to develop a Multi-dimensional Body Image Scale for Malaysian female adolescents. Data were collected among 328 female adolescents from a secondary school in Kuantan district, state of Pahang, Malaysia by using a self-administered questionnaire and anthropometric measurements. The self-administered questionnaire comprised multiple measures of body image, Eating Attitude Test (EAT-26; Garner & Garfinkel, 1979) and Rosenberg Self-esteem Inventory (Rosenberg, 1965). The 152 items from selected multiple measures of body image were examined through factor analysis and for internal consistency. Correlations between Multi-dimensional Body Image Scale and body mass index (BMI), risk of eating disorders and self-esteem were assessed for construct validity. A seven factor model of a 62-item Multi-dimensional Body Image Scale for Malaysian female adolescents with construct validity and good internal consistency was developed. The scale encompasses 1) preoccupation with thinness and dieting behavior, 2) appearance and body satisfaction, 3) body importance, 4) muscle increasing behavior, 5) extreme dieting behavior, 6) appearance importance, and 7) perception of size and shape dimensions. Besides, a multidimensional body image composite score was proposed to screen negative body image risk in female adolescents. The result found body image was correlated with BMI, risk of eating disorders and self-esteem in female adolescents. In short, the present study supports a multi-dimensional concept for body image and provides a new insight into its multi-dimensionality in Malaysian female adolescents with preliminary validity and reliability of the scale. The Multi-dimensional Body Image Scale can be used to identify female adolescents who are potentially at risk of developing body image disturbance through future intervention programs. PMID:20126371

Positron Emission Tomography is widely used in three dimensional imaging of metabolic body function and in tumor detection. Important research efforts are made to improve this imaging modality and powerful simulators such as GATE are used to test and develop methods for this purpose. PET requires acquisition time in the order of few minutes. Therefore, because of the natural patient movements such as respiration, the image quality can be adversely affected which drives scientists to develop motion compensation methods to improve the image quality. The goal of this study is to evaluate various image reconstructions methods with GATE simulation of a PET acquisition of the torso area. Obtained results show the need to compensate natural respiratory movements in order to obtain an image with similar quality as the reference image. Improvements are still possible in the applied motion field's extraction algorithms. Finally a statistical analysis should confirm the obtained results.

Media ideals and early adolescents' body image: Selective avoidance or selective exposure?

PubMed

Rousseau, Ann; Eggermont, Steven

2018-06-05

The present study combines selective exposure theory with body image coping literature to study effects of media internalization in early adolescence. The main objective was to explore how early adolescents selectively internalize media body ideals to manage their body image. To examine the role of media internalization in early adolescents' body image management, we used two-wave panel data (N Wave1  = 1986) gathered among 9- to 14-year-olds. Structural equation analyses indicated that media internalization (Wave 1) positively related to body surveillance (Wave 2). Body surveillance (Wave 2), in turn, was associated with more body image self-discrepancy (Wave 2). In addition, body image self-discrepancy (Wave 1) related to higher body surveillance (Wave 1). Body surveillance, in turn, related to more media internalization cross-sectionally, but less media internalization six months later. Taken together, these results suggest a role for media internalization in early adolescents' body image management. Theoretical and practical implications are discussed.

Studies examining associations between positive body image and well-being have used a limited array of measures of each construct. To rectify this, we asked an online sample of 1148 U.K. adults to complete a range of measures of positive body image (body appreciation, body image flexibility, body pride, body acceptance from others) and a multi-dimensional measure of well-being (emotional, psychological, and social). Results showed that, once the effects of age and body mass index (BMI) had been accounted for, body appreciation significantly predicted all dimensions of well-being. Other positive body image measures emerged as significant predictors, but patterns of associations were mixed across sex and well-being dimension. Additional analyses showed that women had significantly lower scores than men on most body image measures, and that BMI was negatively associated with all body image measures. These results have implications for the promotion of well-being, which we discuss.

The phenomenology of deep hypnosis: quiescent and physically active.

2005-01-01

To study the phenomenology of hypnotic virtuosos, the author employed a 2 (hypnosis vs. control) x 3 (quiescent, pedaling a stationary bike, having a motor pedal the bike) within-subjects design with quantitative and qualitative measures. In a "neutral hypnosis" context with the only suggestion being to go as deeply into hypnosis as possible, participants reported alterations in body image, time sense, perception and meaning, sense of being in an altered state of awareness, affect, attention, and imagery. They also mentioned less self-awareness, rationality, voluntary control, and memory. Analyses of the 3 physical conditions showed that hypnotic experiences were overall similar, although quiescence was more conducive to alterations of body image and reports of depth. These results suggest that hypnotic virtuosos have alterations of consciousness that can be better conceptualized as distinct states rather than being on a continuum.

Dissatisfaction with own body makes patients with eating disorders more sensitive to pain

Body image represents a multidimensional concept including body image evaluation and perception of body appearance. Disturbances of body image perception are considered to be one of the central aspects of anorexia nervosa and bulimia nervosa. There is growing evidence that body image distortion can be associated with changes in pain perception. The aim of our study was to examine the associations between body image perception, body dissatisfaction, and nociception in women with eating disorders and age-matched healthy control women. We measured body dissatisfaction and pain sensitivity in 61 patients with Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition diagnoses of eating disorders (31 anorexia nervosa and 30 bulimia nervosa) and in 30 healthy women. Thermal pain threshold latencies were evaluated using an analgesia meter and body image perception and body dissatisfaction were assessed using Anamorphic Micro software (digital pictures of their own body distorted into larger-body and thinner-body images). Patients with eating disorders overestimated their body size in comparison with healthy controls, but the two groups did not differ in body dissatisfaction. In anorexia and bulimia patient groups, body dissatisfaction (calculated in pixels as desired size/true image size) correlated with pain threshold latencies (r=0.55, p=0.001), while between body image perception (determined as estimation size/true image size) and pain threshold, no correlation was found. Thus, we demonstrated that in patients with eating disorders, pain perception is significantly associated with emotional contrary to sensory (visual) processing of one’s own body image. The more the patients desired to be thin, the more pain-sensitive they were. Our findings based on some shared mechanisms of body dissatisfaction and pain perception support the significance of negative emotions specific for eating disorders and contribute to better understanding of the psychosomatic characteristics of this spectrum of illnesses.

This study aimed to assess possible relationships and predictor variables between disordered eating attitudes and behaviors, the internalization of the thin ideal construct, body image satisfaction, body image investment, weight-related anxiety, and body mass index (BMI) among Greek-Cypriot female university students in Cyprus. A total of 243 female university students responded to self-report measures assessing disordered eating, internalization of the thin ideal, body satisfaction, body image investment, and weight-related anxiety. Disordered eating was positively correlated to the internalization of the thin ideal, body image investment, weight-related anxiety, and BMI and negatively correlated with body image satisfaction. The internalization of the thin ideal was also positively correlated to weight-related anxiety and body image investment and negatively correlated to body image satisfaction. Furthermore, weight-related anxiety and internalization of the thin ideal have been found to be significant predictors of disordered eating attitudes. Possible explanations and vulnerability factors are addressed, as well as implication for prevention strategies and future research. © 2014 Wiley Periodicals, Inc.

2016-01-01

Objective The purpose of this study was to describe body image concerns for surgically treated patients with head and neck cancer and evaluate the relationship between body image concerns and quality of life outcomes. Methods Data were obtained from 280 patients undergoing surgical treatment for head and neck cancer. We used a cross-sectional design and obtained data from individuals at different time points relative to initiation of surgical treatment. Participants completed the Body Image Scale, the Functional Assessment of Cancer Therapy scale – Head and Neck version, and a survey designed for this study to evaluate disease-specific body image issues, satisfaction with care regarding body image issues, and interest in psychosocial intervention. Results Body image concerns were prevalent in the majority of participants with 75% acknowledging concerns or embarrassment about one or more types of bodily changes at some point during treatment. Significant associations were found between body image concerns and all major domains of quality of life. Age, gender, cancer type, time since surgery, and body image variables were significantly associated with psychosocial outcomes. A clear subset of participants expressed dissatisfaction with care received about body image issues and/or indicated they would have liked additional resources to help them cope with body image changes. Conclusions These data provide useful information to document wide-ranging body image difficulties for this population and provide important targets for the development of relevant psychosocial interventions.

This study investigated the potential mediating roles of body comparisons with peers and models in the relationship between the internalization of thinness norms and body image concern. A total of 224 Western Australian girls aged 14-15 completed questionnaires assessing their endorsement of thinness norms, body image concerns, and frequency of body comparisons with peers and with models. Both targets of body comparisons were found to significantly mediate the relationship between the endorsement of thinness norms and body image concern, with body comparison with peers a stronger mediator than comparison with models. These findings show that body comparison with peers, in particular, plays a significant role in the experience of body image concerns among adolescent girls, and should be given a higher profile in programs designed to prevent or reduce body image concern.

Automatic anatomy recognition in whole-body PET/CT images

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wang, Huiqian; Udupa, Jayaram K., E-mail: jay@mail.med.upenn.edu; Odhner, Dewey

Purpose: Whole-body positron emission tomography/computed tomography (PET/CT) has become a standard method of imaging patients with various disease conditions, especially cancer. Body-wide accurate quantification of disease burden in PET/CT images is important for characterizing lesions, staging disease, prognosticating patient outcome, planning treatment, and evaluating disease response to therapeutic interventions. However, body-wide anatomy recognition in PET/CT is a critical first step for accurately and automatically quantifying disease body-wide, body-region-wise, and organwise. This latter process, however, has remained a challenge due to the lower quality of the anatomic information portrayed in the CT component of this imaging modality and the paucity ofmore » anatomic details in the PET component. In this paper, the authors demonstrate the adaptation of a recently developed automatic anatomy recognition (AAR) methodology [Udupa et al., “Body-wide hierarchical fuzzy modeling, recognition, and delineation of anatomy in medical images,” Med. Image Anal. 18, 752–771 (2014)] to PET/CT images. Their goal was to test what level of object localization accuracy can be achieved on PET/CT compared to that achieved on diagnostic CT images. Methods: The authors advance the AAR approach in this work in three fronts: (i) from body-region-wise treatment in the work of Udupa et al. to whole body; (ii) from the use of image intensity in optimal object recognition in the work of Udupa et al. to intensity plus object-specific texture properties, and (iii) from the intramodality model-building-recognition strategy to the intermodality approach. The whole-body approach allows consideration of relationships among objects in different body regions, which was previously not possible. Consideration of object texture allows generalizing the previous optimal threshold-based fuzzy model recognition method from intensity images to any derived fuzzy membership image, and in the process, to bring performance to the level achieved on diagnostic CT and MR images in body-region-wise approaches. The intermodality approach fosters the use of already existing fuzzy models, previously created from diagnostic CT images, on PET/CT and other derived images, thus truly separating the modality-independent object assembly anatomy from modality-specific tissue property portrayal in the image. Results: Key ways of combining the above three basic ideas lead them to 15 different strategies for recognizing objects in PET/CT images. Utilizing 50 diagnostic CT image data sets from the thoracic and abdominal body regions and 16 whole-body PET/CT image data sets, the authors compare the recognition performance among these 15 strategies on 18 objects from the thorax, abdomen, and pelvis in object localization error and size estimation error. Particularly on texture membership images, object localization is within three voxels on whole-body low-dose CT images and 2 voxels on body-region-wise low-dose images of known true locations. Surprisingly, even on direct body-region-wise PET images, localization error within 3 voxels seems possible. Conclusions: The previous body-region-wise approach can be extended to whole-body torso with similar object localization performance. Combined use of image texture and intensity property yields the best object localization accuracy. In both body-region-wise and whole-body approaches, recognition performance on low-dose CT images reaches levels previously achieved on diagnostic CT images. The best object recognition strategy varies among objects; the proposed framework however allows employing a strategy that is optimal for each object.« less

The Virtual Dollhouse: Body Image and Weight Stigma in Second Life

NASA Astrophysics Data System (ADS)

Linares, R.; Bailenson, J.; Bailey, J.; Stevenson Won, A.

2012-12-01

Second Life is a virtual world where fantasy and reality collide as users can customize their digital representation or avatar. The act of wanting to ignore or avoid the real world's physical limitations can be called "avatar escapism" (Ducheneaut, Wen, Yee, Wadley, 2009). In the media the increasingly thin standard of beauty (Berel, Irving, 1998) has augmented negative stereotypes of overweight people to the point of making it acceptable for people to ridicule others' bodies image (Wang, Brownell, Wadden, 2004). In the real world, these concepts hurt people who are unable or unwilling to achieve an "acceptable" body size often leading them to be ridiculed. In the virtual world, a person may portray their desired body potentially escaping judgment from others. Can this more liberated form of bodily expression lead people to expect and need that perfection to a point where they abandon the real world in order to live in that perfection? With this knowledge we looked at the implications of the real world idolization of the perfect body and how this is transferred into the virtual space. In addition, we investigated how the reactions and behaviors that people have when others rebel against the "Barbie doll" appearance (Ducheneaut, Wen, Yee, Wadley, 2009) affect us in the real world.

Sociocultural and individual psychological predictors of body image in young girls: a prospective study.

PubMed

Clark, Levina; Tiggemann, Marika

2008-07-01

This study investigated the prospective predictors of body image in 9- to 12-year-old girls. Participants were 150 girls in Grades 4-6 with a mean age of 10.3 years. Girls completed questionnaire measures of media and peer influences (television/magazine exposure, peer appearance conversations), individual psychological variables (appearance schemas, internalization of appearance ideals, autonomy), and body image (figure discrepancy and body esteem) at Time 1 and 1 year later at Time 2. Linear panel analyses showed that after controlling for Time 1 levels of body image, none of the Time 1 sociocultural variables predicted body image variables at Time 2. Body mass index (BMI; a biological variable) and psychological variables, however, did offer significant prospective prediction. Specifically, higher BMI, higher appearance schemas, higher internalization of appearance ideals, and lower autonomy predicted worsening body image 1 year later. Thus, higher weight and certain psychological characteristics were temporally antecedent to body image concerns. It was concluded that both biological and individual psychological variables play a role in the development of body image in children. Individual psychological variables, in particular, may provide useful targets in prevention and intervention programs addressing body image in 9- to 12-year-old girls.

"Body" is a basic concept of both the natural and human sciences. This extensive review of the literature explores the various philosophical approaches to the body, including empiricism, idealism, existentialism and phenomenology, as well as the relationship between body and mind. Embodiment and body image are the two main concepts of body addressed in this article. Merleau-Ponty's perspective on embodiment, an important new area of theory development, emphasizes that embodiment research must focus on life experiences, such as the study of body image. Using Schilder's framework of psychosocialology, this article provides a comprehensive understanding of the concept of body image and women's perspectives on the "body" in both Western culture and Eastern cultures. Body size and shape significantly influence the self-image of women. Body image is something that develops and changes throughout one's life span and is continually being constructed, destructed, and reconstructed. Personal body image has important psychological effects on the individual, especially women. This integrative review can make a significant contribution to knowledge in this area and, consequently, to related practice and research.

Associations Between Positive Body Image, Sexual Liberalism, and Unconventional Sexual Practices in U.S. Adults.

2017-11-01

While studies have documented robust relationships between body image and sexual health outcomes, few studies have looked beyond sexual functioning in women. Here, we hypothesized that more positive body image would be associated with greater sexual liberalism and more positive attitudes toward unconventional sexual practices. An online sample of 151 women and 164 men from the U.S. completed measures of sexual liberalism, attitudes toward unconventional sexual practices, and indices of positive body image (i.e., body appreciation, body acceptance by others, body image flexibility, and body pride), and provided their demographic details. Regression analyses indicated that, once the effects of sexual orientation, relationship status, age, and body mass index had been accounted for, higher body appreciation was significantly associated with greater sexual liberalism in women and men. Furthermore, higher body appreciation and body image flexibility were significantly associated with more positive attitudes toward unconventional sexual practices in women and men. These results may have implications for scholars working from a sex-positive perspective, particularly in terms of understanding the role body image plays in sexual attitudes and behaviors.

Essentials of forensic post-mortem MR imaging in adults.

Ruder, T D; Thali, M J; Hatch, G M

2014-04-01

Post-mortem MR (PMMR) imaging is a powerful diagnostic tool with a wide scope in forensic radiology. In the past 20 years, PMMR has been used as both an adjunct and an alternative to autopsy. The role of PMMR in forensic death investigations largely depends on the rules and habits of local jurisdictions, availability of experts, financial resources, and individual case circumstances. PMMR images are affected by post-mortem changes, including position-dependent sedimentation, variable body temperature and decomposition. Investigators must be familiar with the appearance of normal findings on PMMR to distinguish them from disease or injury. Coronal whole-body images provide a comprehensive overview. Notably, short tau inversion-recovery (STIR) images enable investigators to screen for pathological fluid accumulation, to which we refer as "forensic sentinel sign". If scan time is short, subsequent PMMR imaging may be focussed on regions with a positive forensic sentinel sign. PMMR offers excellent anatomical detail and is especially useful to visualize pathologies of the brain, heart, subcutaneous fat tissue and abdominal organs. PMMR may also be used to document skeletal injury. Cardiovascular imaging is a core area of PMMR imaging and growing evidence indicates that PMMR is able to detect ischaemic injury at an earlier stage than traditional autopsy and routine histology. The aim of this review is to present an overview of normal findings on forensic PMMR, provide general advice on the application of PMMR and summarise the current literature on PMMR imaging of the head and neck, cardiovascular system, abdomen and musculoskeletal system.

To achieve a detailed view of the body image of transsexual patients, an assessment of perception, attitudes and experiences about one's own body is necessary. To date, research on the body image of transsexual patients has mostly covered body dissatisfaction with respect to body perception. We investigated 23 preoperative (16 male-to-female and 7 female-to-male transsexual patients) and 22 postoperative (14 male-to-female and 8 female-to-male) transsexual patients using a validated psychological measure for body image variables. We found that preoperative transsexual patients were insecure and felt unattractive because of concerns about their body image. However, postoperative transsexual patients scored high on attractiveness and self-confidence. Furthermore, postoperative transsexual patients showed low scores for insecurity and concerns about their body. Our results indicate an improvement of body image concerns for transsexual patients following standards of care for gender identity disorder. Follow-up studies are recommended to confirm the assumed positive outcome of standards of care on body image. (c) 2007 S. Karger AG, Basel.

Tool-use: An open window into body representation and its plasticity

ABSTRACT Over the last decades, scientists have questioned the origin of the exquisite human mastery of tools. Seminal studies in monkeys, healthy participants and brain-damaged patients have primarily focused on the plastic changes that tool-use induces on spatial representations. More recently, we focused on the modifications tool-use must exert on the sensorimotor system and highlighted plastic changes at the level of the body representation used by the brain to control our movements, i.e., the Body Schema. Evidence is emerging for tool-use to affect also more visually and conceptually based representations of the body, such as the Body Image. Here we offer a critical review of the way different tool-use paradigms have been, and should be, used to try disentangling the critical features that are responsible for tool incorporation into different body representations. We will conclude that tool-use may offer a very valuable means to investigate high-order body representations and their plasticity. PMID:27315277

Understanding factors related to girls' body image discrepancy, which is the difference between self-perceived current or actual and ideal body size, is important for addressing body-related issues and preventing adverse sequelae. Two aims were to: 1) examine demographic differences in body image discrepancy; and 2) determine the association of body image discrepancy with weight status, percent body fat, physical activity, sedentary behavior, and cardiovascular (CV) fitness among young adolescent girls. The cross-sectional study included a secondary analysis of baseline data from a group randomized controlled trial including 1519 5th-8th grade girls in 24 U.S. schools. Girls completed physical activity and sedentary behavior surveys. To indicate perceived current/actual and ideal body image, girls selected from nine body figures the one that represented how they look now and another showing how they want to look. Girls wore accelerometers measuring physical activity. Height, weight, and percent body fat were assessed. The Progressive Aerobic CV Endurance Run was used to estimate CV fitness. Independent t-test, one- and two-way ANOVA, correlational analyses, and hierarchical linear regressions were performed. The majority (67.5%; n = 1023) chose a smaller ideal than current/actual figure. White girls had higher body image discrepancy than Black girls (p = .035). Body image discrepancy increased with increasing weight status (F 3,1506  = 171.32, p < .001). Moderate-to-vigorous physical activity (MVPA) and vigorous physical activity were negatively correlated with body image discrepancy (r = -.10, p < .001; r = -.14, p < .001, respectively), but correlations were not significant after adjusting for race and body mass index (BMI), respectively. Body image discrepancy was moderately correlated with CV fitness (r = -.55, p < .001). After adjusting for demographics, percent body fat, but not CV fitness or MVPA, influenced body image discrepancy. Girls with higher percent body fat had higher body image discrepancy (p < .001). This study provided important information to guide interventions for promoting a positive body image among girls. ClinicalTrials.gov Identifier NCT01503333 , registration date: January 4, 2012.

Person Recognition System Based on a Combination of Body Images from Visible Light and Thermal Cameras.

2017-03-16

The human body contains identity information that can be used for the person recognition (verification/recognition) problem. In this paper, we propose a person recognition method using the information extracted from body images. Our research is novel in the following three ways compared to previous studies. First, we use the images of human body for recognizing individuals. To overcome the limitations of previous studies on body-based person recognition that use only visible light images for recognition, we use human body images captured by two different kinds of camera, including a visible light camera and a thermal camera. The use of two different kinds of body image helps us to reduce the effects of noise, background, and variation in the appearance of a human body. Second, we apply a state-of-the art method, called convolutional neural network (CNN) among various available methods, for image features extraction in order to overcome the limitations of traditional hand-designed image feature extraction methods. Finally, with the extracted image features from body images, the recognition task is performed by measuring the distance between the input and enrolled samples. The experimental results show that the proposed method is efficient for enhancing recognition accuracy compared to systems that use only visible light or thermal images of the human body.

Although sexual functioning has been linked to sexual satisfaction, it only partially explains the degree to which women report being sexually satisfied. Other factors include quality of life, relational variables, and individual factors such as body image. Of the few studies that have investigated the link between body image and sexual satisfaction, most have considered body image to be a single construct and have shown mixed results. The present study assessed multiple body image variables in order to better understand which aspects of body image influence multiple domains of sexual satisfaction, including sexual communication, compatibility, contentment, personal concern, and relational concern in a community sample of women. Women between the ages of 18 and 49 years in sexual relationships (N = 154) participated in an Internet survey that assessed sexual functioning, five domains of sexual satisfaction, and several body image variables. Body image variables included the sexual attractiveness, weight concern, and physical condition subscales of the Body Esteem Scale, the appearance-based subscale of the Cognitive Distractions During Sexual Activity Scale, and body mass index. Total score of the Sexual Satisfaction Scale for Women was the main outcome measure. Sexual functioning was measured by a modified Female Sexual Function Index. Consistent with expectations, correlations indicated significant positive relationships between sexual functioning, sexual satisfaction, and all body image variables. A multiple regression analysis revealed that sexual satisfaction was predicted by high body esteem and low frequency of appearance-based distracting thoughts during sexual activity, even after controlling for sexual functioning status. Several aspects of body image, including weight concern, physical condition, sexual attractiveness, and thoughts about the body during sexual activity predict sexual satisfaction in women. The findings suggest that women who experience low sexual satisfaction may benefit from treatments that target these specific aspects of body image.

Robust water fat separated dual-echo MRI by phase-sensitive reconstruction.

2017-09-01

The purpose of this work was to develop and evaluate a robust water-fat separation method for T1-weighted symmetric two-point Dixon data. A method for water-fat separation by phase unwrapping of the opposite-phase images by phase-sensitive reconstruction (PSR) is introduced. PSR consists of three steps; (1), identification of clusters of tissue voxels; (2), unwrapping of the phase in each cluster by solving Poisson's equation; and (3), finding the correct sign of each unwrapped opposite-phase cluster, so that the water-fat images are assigned the correct identities. Robustness was evaluated by counting the number of water-fat swap artifacts in a total of 733 image volumes. The method was also compared to commercial software. In the water-fat separated image volumes, the PSR method failed to unwrap the phase of one cluster and misclassified 10. One swap was observed in areas affected by motion and was constricted to the affected area. Twenty swaps were observed surrounding susceptibility artifacts, none of which spread outside the artifact affected regions. The PSR method had fewer swaps when compared to commercial software. The PSR method can robustly produce water-fat separated whole-body images based on symmetric two-echo spoiled gradient echo images, under both ideal conditions and in the presence of common artifacts.

Dosch, Alessandra; Ghisletta, Paolo; Van der Linden, Martial

2016-01-01

This study explored the link between body image and desire to engage in sexual activity (dyadic and solitary desire) in adult women living in a long-term couple relationship. Moreover, it considered two psychological factors that may underlie such a link: the occurrence of body-related distracting thoughts during sexual activity and encoding style (i.e., the tendency to rely on preexisting internal schemata versus external information at encoding). A total of 53 women (29 to 47 years old) in heterosexual relationships completed questionnaires assessing sexual desire (dyadic, solitary), body image, body-related distracting thoughts during sexual activity, and encoding style. Results showed that poor body image was associated with low dyadic and solitary sexual desire. Body-related distracting thoughts during sexual activity mediated the link between body image and solitary (but not dyadic) sexual desire. Finally, the mediation of body-related distracting thoughts between body image and solitary sexual desire was moderated by encoding style. A negative body image promoted the occurrence of body-related distracting thoughts during sexual activity, especially in internal encoders. Our study highlights the importance of body image, distracting thoughts, and encoding style in women's solitary sexuality and suggests possible factors that may reduce the impact of those body-related factors in dyadic sexual desire.

"Most girls want to be skinny": body (dis)satisfaction among ethnically diverse women.

Cheney, Ann M

2011-10-01

In this article, I present the findings from an ethnographic study of 18 women college students living in the northeastern United States. I examine how ethnically diverse women dealt with the messages of the dominant White society's obsession with thinness, and whether it affected their perceptions of an ideal body image. From the analysis of the interviews, I identified and extracted several themes related to ethnicity, aesthetic body ideals, body dissatisfaction, and disturbed eating. Grounded in the women's narratives, I found that ethnically diverse women coming of age in American society experience anxieties and emotional stress as they related to others in their daily lives. Their stories shed light on how the body is a vehicle for social mobility and is used by women from marginalized identities to strategically negotiate social inequalities embedded in daily social relationships and interactions that more privileged women do not encounter.

Stewart, Tiffany M

2004-11-01

The treatment of body image has to be multifaceted and should be directed toward the treatment of the whole individual-body, mind, and spirit-with an ultimate culmination of acceptance and compassion for the self. This article presents information on a mindful approach to the treatment of body image as it pertains to concerns with body size and shape. This approach fosters the idea that the treatment process should be one of observation, nonjudgment, neutrality, and acceptance. To this end, this article will depict the conceptualization of body image treatment from a mindful perspective, in which mindfulness serves as the foundation on which the multiple facets of treatment are built. The core components of body image treatment (i.e., cognitive, perceptual, behavioral, and emotional), in the context of mindfulness, are discussed as they relate to the treatment of body image disturbance. This article may be viewed as a theoretical overview of a new treatment concept for body image disturbance.

Creation of an ostomy leads to significant change in the body image of the patient. However, adaptation to this alteration of body image is necessary for rehabilitation following surgery. The objective of this study was to identify the factors that influence adaptation to altered body image. An analytical cross-sectional study was conducted among 41 ostomy patients who were treated at a single tertiary care unit. Body image disturbance questionnaire (BIDQ) was used to assess the perception of body image. Data were analyzed using independent samples t -test (unpaired), Chi-square test, and Spearman's correlation. In our study, the mean BIDQ score was 2.22 (standard deviation ± 0.88). The body image disturbance was significantly associated with younger age ( P < 0.05). The prevalence of body image disturbance was significantly higher among overweight patients ( P < 0.05). Males had a higher BIDQ score than females. Those who had temporary stoma had significantly higher BIDQ score ( P < 0.05). Those who felt depressed or had thoughts of self-harm soon after surgery had significantly high body image disturbance score ( P < 0.05). There was a significant negative correlation with the perception of self-efficacy and body image disturbance ( P < 0.01). There was no significant association between body image disturbance and the diagnosis, type of surgery, or time duration after surgery. Poor adaptation to alteration of body image was associated with younger age, overweight, and temporary stoma. Individuals at risk of poor adaptation should be identified before surgery and counseled before surgery, after surgery, and during follow-up visits.

The research of body image among breast cancer patients is characterized by some limitations, such as the lack of longitudinal studies or the absence of a multidimensional perspective of body image. This study intends to overcome these limitations, by examining the evolution of body image dimensions (investment, emotions and evaluations) from the period of surgery (T1) to 6-months after the treatment's ending (T2). It also aims to explore the predictors of body image at T2 and, simultaneously, the predictive role of initial body image to psychosocial adjustment at T2. A total of 56 breast cancer patients participated in both assessments and completed a battery of instruments that included measures of body image dimensions (appearance investment, self-consciousness of appearance, shame and appearance satisfaction) and psychosocial adjustment (quality of life and emotional distress). Within the dimensions of body image, only shame increased over time. In general, initial levels of investment predicted subsequent body image dimensions and having a mastectomy done was associated with higher shame and lower appearance satisfaction at T2. Initial body image did not predict later adjustment, with the exception of depression, where appearance investment played a relevant role. Our findings contributed to the advance of knowledge in this area, providing relevant data about the evolution of body image dimensions, its predictors and its predictive role on psychosocial adjustment among breast cancer patients. This study also suggested some clinical implications that can assist health professionals to implement strategies focused on body image throughout the disease.

Cathodoluminescence (CL) petrography provides a means of observing petrographic and compositional properties of geological samples not readily observable by other techniques. We report the low-magnification CL images of 60 sections of extraterrestrial materials. The images we report include ordinary chondrites (including type 3 ordinary chondrites and gas-rich regolith breccias), enstatite chondrites, CO chondrites and a CM chondrite, eucrites and a howardite, lunar highland regolith breccias, and lunar soils. The CL images show how primitive materials respond to parent body metamorphism, how the metamorphic history of EL chondrites differs from that of EH chondrites, how dark matrix and light clasts of regolith breccias relate to each other, how metamorphism affects eucrites, the texture of lunar regolith breccias and the distribution of crystallized lunar spherules ("lunar chondrules"), and how regolith working affects the mineral properties of lunar soils. More particularly, we argue that such images are a rich source of new information on the nature and history of these materials and that our efforts to date are a small fraction of what can be done.

The development of an unrealistic ideal body image and body size dissatisfaction among children is common in Western countries, including the USA and many European nations. However, little is known about children's body image perceptions in post-communist countries. This pilot study evaluated body image perceptions in a sample of Czech school-aged children and their parents and compared them with the perceptions of American children and parents. Ninety-seven Czech and 45 American 4th-6th graders and their parents from eight urban schools participated in this study. A previously developed silhouette body image instrument was utilized in a parent questionnaire and during child interviews to measure perceived and ideal body image perceptions of children and parents. Descriptive statistics, independent t-tests and paired t-tests were used to compare differences between children's and parents' perceived and ideal body image perceptions. Associations between body image perceptions and other variables were explored using bivariate correlations. American children had a thinner ideal body image compared with Czech children (P < 0.05). However, a larger proportion of Czech boys desired to be thinner compared with American boys (34.2% vs. 20%). Parent's ideal body image for their children did not differ by nationality (P = 0.858). While the pressure on children to look thinner was apparent among both American and Czech children, Czech children considered a larger body size as more ideal. A future study should evaluate body image perceptions and factors influencing these perceptions in a representative sample of Czech children and parents.

Background: Infertility is a serious problem in a couple's life that affects their marriage relationships. So, dissatisfaction with sexual function resulting from interpersonal problems is common among these couples. This qualitative study aimed to explore the experiences of infertile women in their sexual life. Materials and Methods: This is a qualitative study with a phenomenological approach. The participants were 20 infertile women referring to the health care centers and infertility clinics of Isfahan and were selected through purposive sampling. Data were collected by tape recording of deep interviews and analyzed by Colaizzi's method. Results: Analysis of the participants’ experiences led to five main concepts: “Disturbed in femininity-body image,” “discouragement of sexual relations,” “sacrifice of sexual pleasure for the sake of getting pregnant,” “confusion in sexual relation during infertility treatment,” and “striving to protect their marriage.” Conclusions: Findings revealed that infertility affects women's different aspects of sexual life, especially disturbance in femininity-body image and sexual reluctance. With regard to women's willingness to protect their matrimonial life and prevent sexual trauma as a destroying factor for their family's mental health, it seems sexual counseling is necessary for infertile couples.

Body image refers to a person's sense of their physical appearance and body function. A negative body image self-evaluation may result in psychosocial dysfunction. Crohn's disease and ulcerative colitis are associated with disabling features, and body image dissatisfaction is a concern for many patients with inflammatory bowel disease (IBD). However, no study has assessed body image and its comorbidities in patients with IBD using validated instruments. Our aim was to explore body image dissatisfaction in patients with IBD and assess its relationship with biological and psychosocial variables. We studied 330 patients (median age, 36 yr; range, 18-83; 169 men) using quantitative and qualitative methods. Patients completed a self-administered questionnaire that included a modified Hopwood Body Image Scale, the Cash Body Image Disturbance Questionnaire, and other validated instruments. Clinical and disease activity data were also collected. Body image dissatisfaction was associated with disease activity (P < 0.001) and steroid treatment (P = 0.03) but not with immunotherapy (P = 0.57) or biological (P = 0.55) therapy. Body image dissatisfaction was also associated with low levels of general (P < 0.001) and IBD-specific (P < 0.001) quality of life, self-esteem (P < 0.001), and sexual satisfaction (P < 0.001), and with high levels of anxiety (P < 0.001) and depression (P < 0.001). Qualitative analysis indicated that patients were concerned about both physical and psychosocial consequences of body image dissatisfaction, including steroid side effects and impaired work and social activities. Body image dissatisfaction is common in patients with IBD, relates to specific clinical variables and is associated with significant psychological dysfunction. Its measurement is warranted as part of a comprehensive patient-centered IBD assessment.

Relationships among muscle dysmorphia characteristics, body image quality of life, and coping in males.

2015-09-01

The purpose of this study was to examine relationships among bodybuilding dependence, muscle satisfaction, body image-related quality of life and body image-related coping strategies, and test the hypothesis that muscle dysmorphia characteristics may predict quality of life via coping strategies. Participants (294 males, Mage=20.5 years, SD=3.1) participated in a cross-sectional survey. Participants completed questionnaires assessing muscle satisfaction, bodybuilding dependence, body image-related quality of life and body image-related coping. Quality of life was correlated positively with muscle satisfaction and bodybuilding dependence but negatively with body image coping (P<0.05). Body image coping was correlated positively with bodybuilding dependence and negatively with muscle satisfaction (P<0.05). Mediation analysis found that bodybuilding dependence and muscle satisfaction predicted quality of life both directly and indirectly via body image coping strategies (as evidenced by the bias corrected and accelerated bootstrapped confidence intervals). These results provide preliminary evidence regarding the ways that muscularity concerns might influence body image-related quality of life. Copyright © 2014 Sports Medicine Australia.

Ultrasound is an important and low cost imaging modality used to study the internal organs of human body and blood flow through blood vessels. It uses high frequency sound waves to acquire images of internal organs. It is used to screen normal, benign and malignant tissues of various organs. Healthy and malignant tissues generate different echoes for ultrasound. Hence, it provides useful information about the potential tumor tissues that can be analyzed for diagnostic purposes before therapeutic procedures. Ultrasound images are affected with speckle noise due to an air gap between the transducer probe and the body. The challenge is to design and develop robust image preprocessing, segmentation and feature extraction algorithms to locate the tumor region and to extract subtle information from isolated tumor region for diagnosis. This information can be revealed using a scale space technique such as the Discrete Wavelet Transform (DWT). It decomposes an image into images at different scales using low pass and high pass filters. These filters help to identify the detail or sudden changes in intensity in the image. These changes are reflected in the wavelet coefficients. Various texture, statistical and image based features can be extracted from these coefficients. The extracted features are subjected to statistical analysis to identify the significant features to discriminate normal and malignant ultrasound images using supervised classifiers. This paper presents a review of wavelet techniques used for preprocessing, segmentation and feature extraction of breast, thyroid, ovarian and prostate cancer using ultrasound images.

Differences in male and female perception response to the Pulvers Body Image Scale (PBIS) were examined among 356 freshmen African American students attending an urban historically Black college/university (HBCU). Participants completed a questionnaire identifying images that best represented their current, healthy, and ideal body image. Compared with males, more females selected the normal body image as their ideal (63.3% vs. 15.3%) and healthy body shape (59.3% vs. 15.3%) (p<.001). Compared with females, more males selected the overweight body image as their ideal (44.6% vs. 30.2%) and healthy body shape (52.2% vs. 36.2%) (p<.01). Similarly, more males selected the obese body image as their ideal (40.1% vs. 6.5%) and healthy body shape (32.5% vs. 4.5%) compared with females (p<.001). Male freshmen at an HBCU perceive a larger body image as healthy and ideal more often than their female counterparts, thereby increasing the potential for their weight-related health risks.

Body image flexibility moderates the association between disordered eating cognition and disordered eating behavior in a non-clinical sample of women: a cross-sectional investigation.

Body image flexibility, a regulation process of openly and freely experiencing disordered eating thoughts and body dissatisfaction, has been found to be a buffering factor against disordered eating symptomatology. The present cross-sectional study investigates whether body image flexibility accounts for disordered eating behavior above and beyond disordered eating cognition, mindfulness, and psychological inflexibility in a sample of nonclinical women, and whether body image flexibility moderates the associations between these correlates and disordered eating behavior. Participants were 421 women, age 21±5.3 years old on average, who completed a web-based survey that included the self-report measures of interest. Results demonstrate the incremental effects of body image flexibility on disordered eating behavior above and beyond disordered eating cognition, mindfulness, and psychological inflexibility. Women with greater body image flexibility endorse disordered eating behavior less so than those with lower body image flexibility. Body image flexibility moderates the association between disordered eating cognition and disordered eating behavior; for women with greater body image flexibility, disordered eating cognition is not positively associated with disordered eating behavior.

2017-01-01

The synovium is a specialized tissue lining the synovial joints, bursae, and tendon sheaths of the body. It is affected by various localized or systemic disorders. Synovial diseases can be classified as inflammatory, infectious, degenerative, traumatic, hemorrhagic, and neoplastic. Damage in other intraarticular structures, particularly cartilages, generally occurs as a part of pathologic processes involving the synovium, leading to irreversible joint destruction. Imaging has an essential role in the early detection of synovial diseases prior to irreversible joint damage. Obtaining and understanding characteristic imaging findings of synovial diseases enables a proper diagnosis for early treatment. This article focuses on the recent literature that is related with the role of imaging in synovial disease. PMID:28638696

Body composition changes in pregnancy: measurement, predictors and outcomes

Widen, EM; Gallagher, D

2014-01-01

Prevalence of overweight and obesity has risen in the United States over the past few decades. Concurrent with this rise in obesity has been an increase in pregravid body mass index and gestational weight gain affecting maternal body composition changes in pregnancy. During pregnancy, many of the assumptions inherent in body composition estimation are violated, particularly the hydration of fat-free mass, and available methods are unable to disentangle maternal composition from fetus and supporting tissues; therefore, estimates of maternal body composition during pregnancy are prone to error. Here we review commonly used and available methods for assessing body composition changes in pregnancy, including: (1) anthropometry, (2) total body water, (3) densitometry, (4) imaging, (5) dual-energy X-ray absorptiometry, (6) bioelectrical impedance and (7) ultrasound. Several of these methods can measure regional changes in adipose tissue; however, most of these methods provide only whole-body estimates of fat and fat-free mass. Consideration is given to factors that may influence changes in maternal body composition, as well as long-term maternal and offspring outcomes. Finally, we provide recommendations for future research in this area. PMID:24667754

To analyze high-resolution color photographs of the mouse fundus. A contact fundus camera based on topical endoscopy fundus imaging (TEFI) was built. Fundus photographs of C57 and Balb/c mice obtained by TEFI were qualitatively analyzed. High-resolution digital imaging of the fundus, including the ciliary body, was routinely obtained. The reflectance and contrast of retinal vessels varied significantly with the amount of incident and reflected light and, thus, with the degree of fundus pigmentation. The combination of chromatic and spherical aberration favored blue light imaging, in term of both field and contrast. TEFI is a small, low-cost system that allows high-resolution color fundus imaging and fluorescein angiography in conscious mice. Panretinal imaging is facilitated by the presence of the large rounded lens. TEFI significantly improves the quality of in vivo photography of retina and ciliary process of mice. Resolution is, however, affected by chromatic aberration, and should be improved by monochromatic imaging.

A Sensitive Measurement for Estimating Impressions of Image-Contents

We have investigated Kansei Content that appeals maker's intention to viewer's kansei. An SD method is a very good way to evaluate subjective impression of image-contents. However, because the SD method is performed after subjects view the image-contents, it is difficult to examine impression of detailed scenes of the image-contents in real time. To measure viewer's impression of the image-contents in real time, we have developed a Taikan sensor. With the Taikan sensor, we investigate relations among the image-contents, the grip strength and the body temperature. We also explore the interface of the Taikan sensor to use it easily. In our experiment, a horror movie is used that largely affects emotion of the subjects. Our results show that there is a possibility that the grip strength increases when the subjects view a strained scene and that it is easy to use the Taikan sensor without its circle base that is originally installed.

Devices exploiting waves in the frequency range from 0.1 THz to 10 THz (corresponding to a free-space wavelength ranging from 30 μm to 3 mm) deserve attention as diagnostic technologies for cultural heritage. THz waves are, indeed, non-ionizing radiations capable of penetrating into non-metallic materials, which are opaque to both visible and infrared waves, without implying long term risks to the molecular stability of the exposed objects and humans. Moreover, THz surveys involve low poewr probing waves, are performed without contact with the object and, thanks to the recent developments, which have allowed the commercialization of compact, flexible and portable systems, maybe performed in loco (i.e. in the place where the artworks are usually located). On the other hand, THz devices can be considered as the youngest among the sensing and imaging electromagnetic techniques and their actual potentialities in terms of characterization of artworks is an ongoing research activity. As a contribution within this context, we have performed time of flight THz imaging [1,2] on ceramic and marble objects. In particular, we surveyed majolica tiles produced by Neapolitan ceramists in the 18th and 19th centuries with the aim to gather information on their structure, constructive technique and conservation state. Moreover, we investigated a Marmo di Candoglia fragment in order to characterize the biological attach affecting it. All the surveys were carried out by using the Fiber-Coupled Terahertz Time Domain System (FICO) developed by Z-Omega and available at the Institute of Electromagnetic Sensing of the Environment (IREA). This system is equipped with fiber optic coupled transmitting and receiving probes and with an automatic positioning system enabling to scan a 150 mm x 150 mm area under a reflection measurement configuration. Based on the obtained results we can state that the use of THz waves allows: - the reconstruction of the object topography; - the geometrical characterization of defects; - the imaging of layered structures and inner features. Specifically, as far as majolica tiles are concerned, we obtained cross-section images pointing out the presence of clay body, glaze and pigment layer. Moreover, pigment and glaze losses affecting the integrity of the surveyed objects were imaged, the depth extension of the losses was estimated and clay body inhomogeneities were observed. Finally, by taking into account the retrieved features of the topography and the spatial distribution of the detected clay body inhomogeneities, hypothesis on the clay shaping modalities were inferred. In addition, with reference to the marble fragment, the zones mainly affected by the biological attach were identified. A detailed presentation of the surveys and obtained results will be provided at the conferences. REFERENCES [1] W.L. Chan, J. Deibel, D.M. Mittleman, "Imaging with terahertz radiation" Rep. Prog.

This study examined the relationship between self-esteem, restrained eating, body image and body mass index during pregnancy. A total of 110 pregnant Israeli and UK women completed the Rosenberg Self-Esteem Questionnaire, the Dutch Eating Behaviour Questionnaire, scales to assess body image and demographics. Body mass index was calculated from antenatal records. Regression modelling determined the relationship between variables, countries and body mass index categories. High correlations were found between body image and body mass index with significantly higher body dissatisfaction for Israeli women. Self-esteem scores for pregnant women were similar to those reported for non-pregnant women. Poorer body image and higher prevalence of restrained eating were found in healthy weight Israeli women. © The Author(s) 2013.

The human body contains identity information that can be used for the person recognition (verification/recognition) problem. In this paper, we propose a person recognition method using the information extracted from body images. Our research is novel in the following three ways compared to previous studies. First, we use the images of human body for recognizing individuals. To overcome the limitations of previous studies on body-based person recognition that use only visible light images for recognition, we use human body images captured by two different kinds of camera, including a visible light camera and a thermal camera. The use of two different kinds of body image helps us to reduce the effects of noise, background, and variation in the appearance of a human body. Second, we apply a state-of-the art method, called convolutional neural network (CNN) among various available methods, for image features extraction in order to overcome the limitations of traditional hand-designed image feature extraction methods. Finally, with the extracted image features from body images, the recognition task is performed by measuring the distance between the input and enrolled samples. The experimental results show that the proposed method is efficient for enhancing recognition accuracy compared to systems that use only visible light or thermal images of the human body.

Reconstruction as part of treatment for breast cancer is aimed at mitigating body image concerns after mastectomy. Although algorithms have been developed to objectively assess breast reconstruction outcomes, associations between objectively quantified breast aesthetic appearance and patient-reported body image outcomes have not been examined. Further, the role of appearance investment in explaining a patient's body image is not well understood. We investigated the extent to which objectively quantified breast symmetry and patient-reported appearance investment were associated with body image dissatisfaction in patients undergoing cancer-related breast reconstruction. Breast cancer patients in different stages of reconstruction (n = 190) completed self-report measures of appearance investment and body image dissatisfaction. Vertical extent and horizontal extent symmetry values, which are indicators of breast symmetry, were calculated from clinical photographs. Associations among breast symmetry, appearance investment, body image dissatisfaction, and patient clinical factors were examined. Multi-variable regression was used to evaluate the extent to which symmetry and appearance investment were associated with body image dissatisfaction. Vertical extent symmetry, but not horizontal extent symmetry, was associated with body image dissatisfaction. Decreased vertical extent symmetry (β = -.19, P < .05) and increased appearance investment (β = .45, P < .001) were significantly associated with greater body image dissatisfaction while controlling for clinical factors. Breast symmetry and patient appearance investment both significantly contribute to an understanding of patient-reported body image satisfaction during breast reconstruction treatment.

2014-01-01

Objective Previous correlational and quasi-experimental research has established that weight concerns and negative body image are associated with tobacco smoking, cessation, and relapse, particularly among young women. This study examined the causal influence of body image upon smoking motivation by merging methodologies from the addiction and body image literatures. Design Using a cue-reactivity paradigm, the study tested whether an experimental manipulation designed to challenge women’s body image—specifically, their weight dissatisfaction—influenced their motivation to smoke. Female college smokers (N = 62) were included in a 2 × 2 factorial, within-subjects design (body image cues X smoking cues). Main Outcome Measures Self-reported urge to smoke was the primary dependent measure, with skin conductance as a secondary measure. Results As hypothesized, the presentation of smoking images and thin model images produced greater urges to smoke than control images. Additionally, trait weight concerns moderated the effect of the body image manipulation such that those women with greater weight concerns produced greater craving to the thin model image (when smoking cues were not present). Conclusion These findings provide initial evidence that situational challenges to body image are causally related to smoking motivation. PMID:18979977

Different Facets of Body Image Disturbance in Binge Eating Disorder: A Review

2017-01-01

The goal of the present review is to give an overview of the current findings on various facets of body image disturbance in Binge Eating Disorder such as body dissatisfaction, overconcern with weight and shape, body-related checking and avoidance behavior, misperception of body size, and body-related cognitive bias. In addition, treatments for a disturbed body image in BED and evidence of body image disturbance in youth with binge eating are reviewed. The results show that a disturbed body image in BED is present in the form of overconcern with weight and shape. Furthermore, there are hints that body dissatisfaction, as well as body-related checking and avoidance behavior, are also impaired. Research concerning misperception of body size in BED has been neglected so far, but first findings show that individuals with BED rate their own body shape rather accurately. Furthermore, there are first hints that body-related cognitive biases are present in individuals with BED. Moreover, in children and adolescents, there are first hints that body dissatisfaction, as well as shape and weight concerns, seem to be associated with loss of control and binge eating. Treatments aimed directly at the convertibility of a disturbed body image in BED have revealed encouraging outcomes. In conclusion, body image disturbance seems to occur in BED, and first studies show that it can be treated effectively. PMID:29182531

This study examined appearance-related commentary, body dissatisfaction, and eating disturbance in 924 undergraduate females. Significant group differences were found in type of appearance-related commentary received across weight groups. Overweight and obese women experienced negative weight and shape-related comments at greater frequencies and positive weight and shape-related comments at lower frequencies compared to underweight and normal weight women. A higher frequency of positive weight and shape-related commentary was associated with less body dissatisfaction for all women and less shape and weight concerns for obese women. These findings suggest that the weight status of young women likely influences the appearance-related commentary that they receive and the manner in which such commentary affects their body image and eating behaviors.

Whole-body diffusion-weighted MR image stitching and alignment to anatomical MRI

NASA Astrophysics Data System (ADS)

2017-02-01

Whole-body diffusion-weighted (WB-DW) MRI in combination with anatomical MRI has shown a great poten- tial in bone and soft tissue tumour detection, evaluation of lymph nodes and treatment response assessment. Because of the vast body coverage, whole-body MRI is acquired in separate stations, which are subsequently combined into a whole-body image. However, inter-station and inter-modality image misalignments can occur due to image distortions and patient motion during acquisition, which may lead to inaccurate representations of patient anatomy and hinder visual assessment. Automated and accurate whole-body image formation and alignment of the multi-modal MRI images is therefore crucial. We investigated several registration approaches for the formation or stitching of the whole-body image stations, followed by a deformable alignment of the multi- modal whole-body images. We compared a pairwise approach, where diffusion-weighted (DW) image stations were sequentially aligned to a reference station (pelvis), to a groupwise approach, where all stations were simultaneously mapped to a common reference space while minimizing the overall transformation. For each, a choice of input images and corresponding metrics was investigated. Performance was evaluated by assessing the quality of the obtained whole-body images, and by verifying the accuracy of the alignment with whole-body anatomical sequences. The groupwise registration approach provided the best compromise between the formation of WB- DW images and multi-modal alignment. The fully automated method was found to be robust, making its use in the clinic feasible.

Whole-body MR imaging, bone diffusion imaging: how and why?

Whole-body MRI (W-B MRI) and diffusion-weighted imaging (DWI) are two novel techniques that greatly facilitate the evaluation of many disorders of childhood. In the musculoskeletal system, these techniques primarily aid in the evaluation of the marrow, although there is increasing interest in the study of soft-tissue abnormalities with W-B MRI and of cartilage with DWI.The normal pattern of marrow transformation affects both modalities throughout childhood. Haematopoietic marrow has a much higher signal intensity than fatty marrow on W-B MRI short tau inversion recovery (STIR) images (Darge et al. Eur J Radiol 68:289-298, 2008). Diffusion is greater in haematopoietic marrow than in fatty marrow and decreases in the skeleton with age (Jaramillo et al. Pediatr Radiol 34:S48, 2004). It is important therefore to remember that the entire skeleton is haematopoietic at birth and that there is a process of marrow transformation to fatty marrow. Marrow conversion proceeds from the fingers to the shoulders and from the toes to the hips. Within each bone, fatty marrow transformation begins in the epiphyses, and within the shaft of the long bones fatty marrow transformation begins at the diaphysis and proceeds towards the metaphyses.

Planets can affect debris disk structure by creating gaps, sharp edges, warps, and other potentially observable signatures. However, there is currently no simple way for observers to deduce a disk-shepherding planet's properties from the observed features of the disk. Here we present a single equation that relates a shepherding planet's maximum mass to the debris ring's observed width in scattered light, along with a procedure to estimate the planet's eccentricity and minimum semimajor axis. We accomplish this by performing dynamical N-body simulations of model systems containing a star, a single planet, and an exterior disk of parent bodies and dustmore » grains to determine the resulting debris disk properties over a wide range of input parameters. We find that the relationship between planet mass and debris disk width is linear, with increasing planet mass producing broader debris rings. We apply our methods to five imaged debris rings to constrain the putative planet masses and orbits in each system. Observers can use our empirically derived equation as a guide for future direct imaging searches for planets in debris disk systems. In the fortuitous case of an imaged planet orbiting interior to an imaged disk, the planet's maximum mass can be estimated independent of atmospheric models.« less

The glymphatic pathway expedites clearance of waste, including soluble amyloid β (Aβ) from the brain. Transport through this pathway is controlled by the brain's arousal level because, during sleep or anesthesia, the brain's interstitial space volume expands (compared with wakefulness), resulting in faster waste removal. Humans, as well as animals, exhibit different body postures during sleep, which may also affect waste removal. Therefore, not only the level of consciousness, but also body posture, might affect CSF-interstitial fluid (ISF) exchange efficiency. We used dynamic-contrast-enhanced MRI and kinetic modeling to quantify CSF-ISF exchange rates in anesthetized rodents' brains in supine, prone, or lateral positions. To validate the MRI data and to assess specifically the influence of body posture on clearance of Aβ, we used fluorescence microscopy and radioactive tracers, respectively. The analysis showed that glymphatic transport was most efficient in the lateral position compared with the supine or prone positions. In the prone position, in which the rat's head was in the most upright position (mimicking posture during the awake state), transport was characterized by "retention" of the tracer, slower clearance, and more CSF efflux along larger caliber cervical vessels. The optical imaging and radiotracer studies confirmed that glymphatic transport and Aβ clearance were superior in the lateral and supine positions. We propose that the most popular sleep posture (lateral) has evolved to optimize waste removal during sleep and that posture must be considered in diagnostic imaging procedures developed in the future to assess CSF-ISF transport in humans. The rodent brain removes waste better during sleep or anesthesia compared with the awake state. Animals exhibit different body posture during the awake and sleep states, which might affect the brain's waste removal efficiency. We investigated the influence of body posture on brainwide transport of inert tracers of anesthetized rodents. The major finding of our study was that waste, including Aβ, removal was most efficient in the lateral position (compared with the prone position), which mimics the natural resting/sleeping position of rodents. Although our finding awaits testing in humans, we speculate that the lateral position during sleep has advantage with regard to the removal of waste products including Aβ, because clinical studies have shown that sleep drives Aβ clearance from the brain.

Framed within social self-preservation theory, the present study investigated men’s psychobiological responses to social-evaluative body image threats. University men (n = 66) were randomly assigned to either a high or low social-evaluative body image threat condition. Participants provided saliva samples (to assess cortisol) and completed measures of state body shame prior to and following their condition, during which anthropometric and strength measures were assessed. Baseline corrected values indicated men in the high social-evaluative body image threat condition had higher body shame and cortisol than men in the low social-evaluative body image threat condition. These findings suggest that social evaluation in the context of situations that threaten body image leads to potentially negative psychobiological responses in college men. PMID:28891388

Pregnancy provides an interesting challenge to body image theories in that the natural physiological changes push women further from the socioculturally prescribed thin ideal which these theories hinge upon. The impact that these significant physiological changes have on the woman's body image during pregnancy may depend on the extent to which they retain or revise the ideal. However, little is known about body image experiences during pregnancy. To provide a comprehensive exploration of the body image experiences of pregnant women. Individual structured interviews were conducted with 19 currently pregnant women. Transcriptions were analysed using a thematic content analysis approach. Themes extracted from the qualitative data included: (1) women's body image experiences during pregnancy were complex and changing, and shaped by the salience of specific body parts, the women's expectations for future changes to their body within the perinatal period, the functionality of the body, and their experience of maternity clothing, (2) women were able to negotiate the changes to their bodies as they recognised the functionality of the pregnant body, (3) women were surprised by the public nature of the pregnant body, (4) partner support and positive feedback about the pregnant body was highly valued, and (5) the importance of open communication around weight and body image in antenatal healthcare. Our findings highlight the need for the adaptation and expansion of existing body image theories to be used as a framework for women's experiences of pregnancy. Crown Copyright © 2015.

Musculoskeletal effects of whole-body vibration on animals and humans have become an intensely studied topic recently, due to the potential of applying this method as a non-pharmacological therapy for strengthening bones. It is relatively easy to quantify the transmission of whole-body mechanical vibration through the human skeletal system using accelerometers. However, this is not the case for small-animal pre-clinical studies because currently available accelerometers have a large mass, relative to the mass of the animals, which causes the accelerometers themselves to affect the way vibration is transmitted. Additionally, live animals do not typically remain motionless for long periods, unless they are anesthetized, and they are required to maintain a static standing posture during these studies. These challenges provide the motivation for the development of a method to quantify vibrational transmission in small animals. We present a novel imaging technique to quantify whole-body vibration transmission in small animals using 280 μm diameter tungsten carbide beads implanted into the hind limbs of mice. Employing time-exposure digital x-ray imaging, vibrational amplitude is quantified based on the blurring of the implanted beads caused by the vibrational motion. Our in vivo results have shown this technique is capable of measuring vibration amplitudes as small as 0.1 mm, with precision as small as  ±10 μm, allowing us to distinguish differences in the transmitted vibration at different locations on the hindlimbs of mice.

Impacts of exposure to images of ideal bodies on male body dissatisfaction: a review.

PubMed

Blond, Anna

2008-09-01

Research suggests that young men's body dissatisfaction increases when they see images of attractive muscular men. This article provides the first extensive review of experimental studies exposing men to advertisements or commercials featuring idealized male bodies. Impacts on body dissatisfaction were evaluated by calculating and analyzing effect sizes from 15 studies. The effect sizes indicate that exposure to images of idealized male bodies has a small but statistically significant negative impact on men's body dissatisfaction. Three studies suggest that young men who are dissatisfied with their bodies are at increased risk for negative self-evaluations when exposed to idealized images. Two studies suggest that men who are satisfied with their bodies may be protected against negative impacts from seeing such images.

Factors that Influence Body Image Representations of Black Muslim Women

PubMed Central

2008-01-01

Research on the body image perceptions of black women is limited. Although previous body image studies have explored the intersection between race and gender, the influence of religion has been neglected. Guided by a grounded theory framework, the focus of this investigation, conducted in Upstate New York, USA, was to examine the role of race and religion in the body image perceptions of 22 African-American Sunni Muslim women. Analysis of individual interviews revealed that, in contrast to using standard medical guidelines, participants’ views about their bodies were largely based on positive images of an earlier body size/shape, social and family expectations and contexts, cultural norms and values, and spirituality and religious beliefs. Although the body image perceptions of black Muslim women were similar to those expressed in previous body image studies with black women, participants expressed the importance of highlighting the spiritual versus physical self by adhering to religious guidelines regarding proper dress and appearance. These findings suggest that religion, race, and gender are all important factors to be considered when conducting body image studies with black women. PMID:18384923

Remote sensing and avian influenza: A review of image processing methods for extracting key variables affecting avian influenza virus survival in water from Earth Observation satellites

2010-02-01

Recent studies have highlighted the potential role of water in the transmission of avian influenza (AI) viruses and the existence of often interacting variables that determine the survival rate of these viruses in water; the two main variables are temperature and salinity. Remote sensing has been used to map and monitor water bodies for several decades. In this paper, we review satellite image analysis methods used for water detection and characterization, focusing on the main variables that influence AI virus survival in water. Optical and radar imagery are useful for detecting water bodies at different spatial and temporal scales. Methods to monitor the temperature of large water surfaces are also available. Current methods for estimating other relevant water variables such as salinity, pH, turbidity and water depth are not presently considered to be effective.

2016-10-01

To effectively improve the low contrast of human body region in the infrared images, a combing method of several enhancement methods is utilized to enhance the human body region. Firstly, for the infrared images acquired by Kinect, in order to improve the overall contrast of the infrared images, an Optimal Contrast-Tone Mapping (OCTM) method with multi-iterations is applied to balance the contrast of low-luminosity infrared images. Secondly, to enhance the human body region better, a Level Set algorithm is employed to improve the contour edges of human body region. Finally, to further improve the human body region in infrared images, Laplacian Pyramid decomposition is adopted to enhance the contour-improved human body region. Meanwhile, the background area without human body region is processed by bilateral filtering to improve the overall effect. With theoretical analysis and experimental verification, the results show that the proposed method could effectively enhance the human body region of such infrared images.

The aim of this study was to investigate the relationship between body image, body mass index (BMI), and physical activity in adolescents. The study included 1702 girls and 1547 boys aged 14-16 years. Moderate-to-vigorous physical activity (MVPA) was evaluated by the Physical Activity Screening Measure. Body image was assessed using the Feelings and Attitudes Towards the Body Scale, and participants' BMI was determined based on measured height and weight. Compared to boys, girls reported more negative body image (p<.05). The results of the three-way hierarchical regression revealed that body image was a statistically significant positive predictor of MVPA for adolescents, regardless of BMI. Additionally, body image was a stronger predictor of MVPA in boys than in girls. These findings suggest that body image, rather than BMI, is important in undertaking physical activity in adolescents and should be considered when preparing programs aimed at improving physical activity.

2016-12-01

A lot of research has been done for the extraction of water bodies with multiple satellite images. The Water Indexes with the use of multi-spectral images are the mostly used methods for the water bodies' extraction. In order to extract area of water bodies from satellite images, accuracy may depend on the spatial resolution of images and relative size of the water bodies. To quantify the impact of spatial resolution and size (major and minor lengths) of the water bodies on the accuracy of water area extraction, we use Georgetown Lake, Montana and coalbed methane (CBM) water retention ponds in the Montana Powder River Basin as test sites to evaluate the impact of spatial resolution and the size of water bodies on water area extraction. Data sources used include Landsat images and Google Earth images covering both large water bodies and small ponds. Firstly we used water indices to extract water coverage from Landsat images for both large lake and small ponds. Secondly we used a newly developed visible-index method to extract water coverage from Google Earth images covering both large lake and small ponds. Thirdly, we used the image fusion method in which the Google Earth Images are fused with multi-spectral Landsat images to obtain multi-spectral images of the same high spatial resolution as the Google earth images. The actual area of the lake and ponds are measured using GPS surveys. Results will be compared and the optimal method will be selected for water body extraction.

While body image concerns and interpersonal violence exposure are significant issues for women, their interrelationship has been rarely explored. We examined the associations between severity of acute injuries, symptoms of posttraumatic stress disorder (PTSD), depression and body image distress within a sample of predominantly African-American victims of interpersonal violence (N = 73). Severity of body image distress was significantly associated with each outcome. Moreover, body image distress was a significant, unique predictor of depression but not PTSD severity. We recommend continued exploration of body image concerns to further integrated research on violence against women. PMID:24215653

Introduction Although sexual functioning has been linked to sexual satisfaction, it only partially explains the degree to which women report being sexually satisfied. Other factors include quality of life, relational variables, and individual factors such as body image. Of the few studies that have investigated the link between body image and sexual satisfaction, most have considered body image to be a single construct and have shown mixed results. Aim The present study assessed multiple body image variables in order to better understand which aspects of body image influence multiple domains of sexual satisfaction, including sexual communication, compatibility, contentment, personal concern, and relational concern in a community sample of women. Methods Women between the ages of 18 and 49 years in sexual relationships (N = 154) participated in an Internet survey that assessed sexual functioning, five domains of sexual satisfaction, and several body image variables. Main Outcome Measures Body image variables included the sexual attractiveness, weight concern, and physical condition subscales of the Body Esteem Scale, the appearance-based subscale of the Cognitive Distractions During Sexual Activity Scale, and body mass index. Total score of the Sexual Satisfaction Scale for Women was the main outcome measure. Sexual functioning was measured by a modified Female Sexual Function Index. Results Consistent with expectations, correlations indicated significant positive relationships between sexual functioning, sexual satisfaction, and all body image variables. A multiple regression analysis revealed that sexual satisfaction was predicted by high body esteem and low frequency of appearance-based distracting thoughts during sexual activity, even after controlling for sexual functioning status. Conclusion Several aspects of body image, including weight concern, physical condition, sexual attractiveness, and thoughts about the body during sexual activity predict sexual satisfaction in women. The findings suggest that women who experience low sexual satisfaction may benefit from treatments that target these specific aspects of body image. PMID:19968771

Investigation of Factors Affecting Body Temperature Changes During Routine Clinical Head Magnetic Resonance Imaging

2016-01-01

Background Pulsed radiofrequency (RF) magnetic fields, required to produce magnetic resonance imaging (MRI) signals from tissue during the MRI procedure have been shown to heat tissues. Objectives To investigate the relationship between body temperature rise and the RF power deposited during routine clinical MRI procedures, and to determine the correlation between this effect and the body’s physiological response. Patients and Methods We investigated 69 patients from the Korean national cancer center to identify the main factors that contribute to an increase in body temperature (external factors and the body’s response) during a clinical brain MRI. A routine protocol sequence of MRI scans (1.5 T and 3.0 T) was performed. The patient’s tympanic temperature was recorded before and immediately after the MRI procedure and compared with changes in variables related to the body’s physiological response to heat. Results Our investigation of the physiological response to RF heating indicated a link between increasing age and body temperature. A higher increase in body temperature was observed in older patients after a 3.0-T MRI (r = 0.07, P = 0.29 for 1.5-T MRI; r = 0.45, P = 0.002 for 3.0-T MRI). The relationship between age and body heat was related to the heart rate (HR) and changes in HR during the MRI procedure; a higher RF power combined with a reduction in HR resulted in an increase in body temperature. Conclusion A higher magnetic field strength and a decrease in the HR resulted in an increase in body temperature during the MRI procedure. PMID:27895872

2016-06-01

The current study aimed to investigate the effect of digital alteration disclaimer labels appended to fashion magazine advertisements, as well as instructional condition, on women's social comparison and body dissatisfaction. Participants were 378 female undergraduate students who viewed 11 thin ideal advertisements with either no disclaimer, a generic disclaimer, or a more detailed specific disclaimer. There were three instructional conditions: neutral, distractor, and social comparison. Disclaimer labels did not affect appearance comparison or body dissatisfaction, but instructional condition did, with the social comparison instructions producing the highest appearance comparison and body dissatisfaction. In addition, there was a three-way interaction with trait appearance comparison, such that women high on trait appearance comparison who saw specifically worded disclaimers in the distractor instructional condition experienced increased body dissatisfaction, whereas women low on this trait experienced decreased body dissatisfaction. It seems that both instructions and individual differences may influence responses to disclaimer labels. Copyright © 2016 Elsevier Ltd. All rights reserved.

This study aimed to investigate the factor structure and psychometric properties of a Polish version of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). Data were collected from 721 individuals residing in various regions of Poland. There were two subsamples (n=336, age M=34.95, SD=10.83; and n=385, age M=35.38, SD=10.83). Both principal-axis and confirmatory factor analyses supported the one-dimensional structure of BAS-2 scores. Moreover, full scalar invariance of the BAS-2 in Poland across sex was demonstrated. Scores on the Polish BAS-2 had adequate internal consistency. Convergent validity was demonstrated through significant correlations between BAS-2 scores and variables related to body image (body and appearance self-conscious emotions), well-being (self-esteem, positive affect, and positive orientation), and body mass index. These results indicate that the Polish BAS-2 is an appropriate and psychometrically-sound measure of body appreciation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Semi-automated discrimination of retinal pigmented epithelial cells in two-photon fluorescence images of mouse retinas.

Alexander, Nathan S; Palczewska, Grazyna; Palczewski, Krzysztof

2015-08-01

Automated image segmentation is a critical step toward achieving a quantitative evaluation of disease states with imaging techniques. Two-photon fluorescence microscopy (TPM) has been employed to visualize the retinal pigmented epithelium (RPE) and provide images indicating the health of the retina. However, segmentation of RPE cells within TPM images is difficult due to small differences in fluorescence intensity between cell borders and cell bodies. Here we present a semi-automated method for segmenting RPE cells that relies upon multiple weak features that differentiate cell borders from the remaining image. These features were scored by a search optimization procedure that built up the cell border in segments around a nucleus of interest. With six images used as a test, our method correctly identified cell borders for 69% of nuclei on average. Performance was strongly dependent upon increasing retinosome content in the RPE. TPM image analysis has the potential of providing improved early quantitative assessments of diseases affecting the RPE.

Cosmetic surgery is no longer just for females. More men are opting for cosmetic procedures, with marked increases seen in both minimally invasive and surgical options over the last decade. Compared to females, relatively little work has specifically focused on factors predicting males' attitudes toward cosmetic surgery. Therefore, we evaluated a number of variables that may predict some facet of men's attitudes toward cosmetic surgery according to evidence reported in the literature METHODS: A total of 151 male patients who applied for a surgical or minimally invasive cosmetic surgery procedure (patient group) and 151 healthy male volunteers who do not desire any type of cosmetic procedure (control group) were asked to fill out questionnaires about measures of body image, media exposure (television and magazine), social network site use, masculine gender role stress and religious attitudes. Our findings showed that lower ratings of body image satisfaction, increased time spent watching television, more frequent social network site use and higher degrees of masculine gender role stress were all significant predictors of attitudes toward cosmetic surgery among males. The current study confirmed the importance of body image dissatisfaction as a predictor of the choice to undergo cosmetic procedure. More importantly, a new predictor of cosmetic procedure attitudes was identified, namely masculine gender role stress. Finally, we demonstrated the effects television exposure and social network site use in promoting acceptance of surgical and nonsurgical routes to appearance enhancement.

The link between intentions and action in weight control is weaker than previously thought, so recent research has called for further investigation of ways to improve weight control that bypass conscious intentions. Priming has been shown to have effects on individual behavior in a variety of contexts by influencing subconscious cognition. This paper investigates the effects of semantic priming using healthy body image, goal-oriented words on food consumption. The moderating role of both restrained eating and gender is investigated. 161 participants were involved in an experiment using a novel version of a scrambled sentence priming game. The outcome measure was the number of kilocalories consumed, examined using a between subjects ANCOVA with priming, gender, restrained eating index, self-reported BMI, and two interaction terms (primingxgender, and primingxrestrained eating index). There was no main effect of priming but there was an interaction of priming with gender. Females consumed significantly fewer kilocalories after being exposed to priming words related to a healthy body image (i.e. "slim", "fit,") compared to females receiving the neutral prime, with a medium effect size (d = 0.58). The body image prime did not significantly affect food intake for males, nor did it have a differential effect on restrained eaters. This study shows that priming can be an effective method for influencing females to reduce food intake, regardless of whether they are restrained or unrestrained eaters. Future studies could investigate whether different priming words related to a male's healthy body image goal (i.e. "buff," "muscles," etc.) would similarly reduce food intake for males.

This cross-sectional study examined the role of maternal body image and body image self-consciousness in sexual satisfaction and intercourse frequency during pregnancy when controlling for satisfaction with partnership. Pregnant women in their third trimester of pregnancy (N = 150) participated in the study. Body image was measured by the Body Areas Satisfaction Scale (BASS) and Body Image Self-Consciousness Scale (BISC), while relationship satisfaction was measured by different subscales of the Perceived Quality of Marital Relationship (PQMR) Scale. Sexual satisfaction was also measured by one of the subscales of the PQMR (Intimate Relationship). The sexual behavior questionnaire comprised questions about frequency of sexual intercourse, desire, and other aspects of sexual functioning as well as the reasons that might prevent women from having intercourse during pregnancy. Findings suggested that satisfaction with body image and body image self-consciousness were related to sexual satisfaction. Nevertheless, other aspects of partnership, such as communication, appeared to be much more important predictors of sexual satisfaction than body image variables. The best predictor of sexual frequency was fear that intercourse might harm the fetus. Implications for education about sexuality issues in pregnancy are discussed.

Reducing the negative effects of media exposure on body image: Testing the effectiveness of subvertising and disclaimer labels.

2016-06-01

Body image activists have proposed adding disclaimer labels to digitally altered media as a way to promote positive body image. Another approach advocated by activists is to alter advertisements through subvertising (adding social commentary to the image to undermine the message of the advertisement). We examined if body image could be enhanced by attaching Photoshop disclaimers or subvertising to thin-ideal media images of swimsuit models. In Study 1 (N=1268), adult women exposed to disclaimers or subvertising did not report higher body state satisfaction or lower drive for thinness than women exposed to unaltered images. In Study 2 (N=820), adult women who were exposed to disclaimers or subvertising did not report higher state body satisfaction or lower state social appearance comparisons than women exposed to unaltered images or to no images. These results raise questions about the effectiveness of disclaimers and subvertising for promoting body satisfaction. Copyright © 2016 Elsevier Ltd. All rights reserved.

2016-05-01

The increasing prevalence of negative body perceptions among adolescent girls and the tendency towards wishing to be thinner have become a cultural norm in Western culture. Adolescent girls are particularly vulnerable to developing a negative body image due to physical and sexual changes occurring during puberty. This study aimed to evaluate the association between different measures of body image perceptions and different phases of the menstrual cycle after controlling for weight status and other potential confounders in Polish adolescent girls aged 12-18 years. Three-hundred and thirty participants of a cross-sectional survey conducted in 2009, normally cycling and with no eating disorders, completed a background questionnaire and the Stunkard Figure Rating Scale, and their anthropometric measurements were collected. The dependent outcome variables were measures of body image (actual body image, ideal body image and ideal-self discrepancy) and dichotomous body image perception (satisfied versus dissatisfied) adjusted for other predictor factors: socio-demographic variables, menstrual history and cycle phases, and weight status. One-way ANOVA indicated that weight status, age at menarche and menstrual cycle phase were associated with actual body image and rate of ideal-self discrepancy. Ideal body image was associated with weight status and menstrual cycle phase. General logistic regression models were constructed to evaluate associations of body dissatisfaction and all potential predictor variables. The final selected model of the multiple logistic regression analysis using the backward elimination procedure revealed that adjusted for other factors, negative body image was significantly associated with different phases of the menstrual cycle (p trend=0.033) and increasing body weight status (p trend=0.0007). The likelihood of body dissatisfaction was greatest during the premenstrual phase of the menstrual cycle (OR=2.38; 95% CI 1.06, 5.32) and among girls in obesity class I (OR=8.04; 95% CI 2.37, 27.26). The study confirmed the association between body image dissatisfaction in adolescent girls and different phases of the menstrual cycle after controlling for weight status. The issue of negative body self-image is not only of cognitive, but also of practical value as understanding better the factors contributing to the formation of a negative body image may be instrumental in developing preventive health programmes targeted at young people.

Manaf, Nurajirahbt Abdul; Zuhrah, Beevi

2016-01-01

Introduction Female students are thought to be more negatively impacted by body image ideals and often more susceptible to various eating related disorders compared to men. A previous study using a sample of female students in Malaysia did not identify whether the increase in susceptibility to eating disorders can be explained by the level of body image acceptance. Aim To identify the prevalence of depression and susceptibility to eating disorders among a sample of 206 female students in one of the private universities in Malaysia and explore the relationship between depression, body image and susceptibility to eating disorders. In addition, this study aimed to determine whether depression is a mediator between body image and susceptibility to eating disorders among female college students. Materials and Methods The Body Image Acceptance and Action Questionnaire were used to assess body image acceptance, the Patient Health Questionnaire to measure depression and the Eating Attitude Test- 26 was used to assess susceptibility to eating disorders. Results The results showed that 65.5% (n=135) of the students were depressed and 6.3% (n=13) were susceptible to eating disorders. There was a significant positive relationship between depression and eating disorders and a negative relationship between body image and depression as well as between body image and eating disorder. Further, the regression model showed that depression was partially mediating the effect of body image on eating disorders. Conclusion Body image and depression contribute to eating disorders and treating depression could reduce susceptibility to eating disorders. PMID:27134977

Comparative effects of Facebook and conventional media on body image dissatisfaction.

Appearance comparison has consistently been shown to engender body image dissatisfaction. To date, most studies have demonstrated this relationship between appearance comparison and body image dissatisfaction in the context of conventional media images depicting the thin-ideal. Social comparison theory posits that people are more likely to compare themselves to similar others. Since social media forums such as Facebook involve one's peers, the current study aimed to determine whether the relationship between appearance comparison and body image dissatisfaction would be stronger for those exposed to social media images, compared to conventional media images. A sample of 193 female first year university students were randomly allocated to view a series of either Facebook or conventional media thin-ideal images. Participants completed questionnaires assessing pre- and post- image exposure measures of thin-ideal internalisation, appearance comparison, self-esteem, Facebook use and eating disorder risk. Type of exposure was not found to moderate the relationship between appearance comparison and changes in body image dissatisfaction. When analysed according to exposure type, appearance comparison only significantly predicted body image dissatisfaction change for those exposed to Facebook, but not conventional media. Facebook use was found to predict higher baseline body image dissatisfaction and was associated with higher eating disorder risk. The findings suggest the importance of extending the body image dissatisfaction literature by taking into account emerging social media formats. It is recommended that interventions for body image dissatisfaction and eating disorders consider appearance comparison processes elicited by thin-ideal content on social media forums, such as Facebook, in addition to conventional media.

Depressive symptoms have been reported as prevalent after bariatric surgery. This study aims to analyze the role of weight, eating behaviors and body image in depressive symptomatology in bariatric surgery patients assessed post-operatively. This is a cross-sectional study including 52 bariatric surgery patients assessed post-operatively with a follow-up time ranging from 22 to 132 months. Psychological assessment included a clinical interview (Eating Disorder Examination) to assess eating disorders psychopathology, and three self-report measures: Outcome Questionnaire 45--general distress; Beck Depression Inventory--depressive symptoms; and Body Shape Questionnaire--body image. Our data show that depressive symptoms after surgery are associated with loss of control over eating, increased concerns with body image, and body mass index regain. Multiple linear regressions was tested including these variables and showed that body mass index regain after surgery, loss of control over eating and concerns with body image significantly explained 50% of the variance of post-operative depressive symptoms, being the concern with body image the most significant variable: greater dissatisfaction with body image was associated with more depressive symptoms. The results of this study showed that a subgroup of patients presents a significant weight gain after bariatric surgery, which is associated with episodes of loss of control over eating, concerns with body image and depressive symptoms. These results stress the relevance of body image concerns after surgery and the importance of clinically addressing these issues to optimize psychological functioning after bariatric surgery.

This study tested Expand Your Horizon, a programme designed to improve body image by training women to focus on the functionality of their body using structured writing assignments. Eighty-one women (Mage=22.77) with a negative body image were randomised to the Expand Your Horizon programme or to an active control programme. Appearance satisfaction, functionality satisfaction, body appreciation, and self-objectification were measured at pretest, posttest, and one-week follow-up. Following the intervention, participants in the Expand Your Horizon programme experienced greater appearance satisfaction, functionality satisfaction, and body appreciation, and lower levels of self-objectification, compared to participants in the control programme. Partial eta-squared effect sizes were of small to medium magnitude. This study is the first to show that focusing on body functionality can improve body image and reduce self-objectification in women with a negative body image. These findings provide support for addressing body functionality in programmes designed to improve body image. Copyright © 2015 Elsevier Ltd. All rights reserved.

Abstract Hemangiopericytoma, a rare mesenchymal tumour, is believed to originate from the pericyte of Zimmermann. It may affect every organ in the body. Recurrences after treatment and metastasis are well known. However, presentation of hemangiopericytoma with peritoneal carcinomatosis is not documented in literature. To the best our knowledge, we report the imaging findings of the first histologically proven case of hemangiopericytoma with peritoneal carcinomatosis. PMID:19602469

Studies have suggested associations between personality dimensions and body image constructs, but these have not been conclusively established. In two studies, we examined direct associations between the Big Five dimensions and two body image constructs, actual-ideal weight discrepancy and body appreciation. In Study 1, 950 women completed measures of both body image constructs and a brief measure of the Big Five dimensions. In Study 2,339 women completed measures of the body image constructs and a more reliable measure of the Big Five. Both studies showed that Neuroticism was significantly associated with actual-ideal weight discrepancy (positively) and body appreciation (negatively) once the effects of body mass index and social status had been accounted for. These results are consistent with the suggestion that Neuroticism is a trait of public health significance requiring attention by body image scholars. © 2012 The Authors.

Essentials of forensic post-mortem MR imaging in adults

PubMed Central

Ruder, T D; Thali, M J; Hatch, G M

2014-01-01

Post-mortem MR (PMMR) imaging is a powerful diagnostic tool with a wide scope in forensic radiology. In the past 20 years, PMMR has been used as both an adjunct and an alternative to autopsy. The role of PMMR in forensic death investigations largely depends on the rules and habits of local jurisdictions, availability of experts, financial resources, and individual case circumstances. PMMR images are affected by post-mortem changes, including position-dependent sedimentation, variable body temperature and decomposition. Investigators must be familiar with the appearance of normal findings on PMMR to distinguish them from disease or injury. Coronal whole-body images provide a comprehensive overview. Notably, short tau inversion–recovery (STIR) images enable investigators to screen for pathological fluid accumulation, to which we refer as “forensic sentinel sign”. If scan time is short, subsequent PMMR imaging may be focussed on regions with a positive forensic sentinel sign. PMMR offers excellent anatomical detail and is especially useful to visualize pathologies of the brain, heart, subcutaneous fat tissue and abdominal organs. PMMR may also be used to document skeletal injury. Cardiovascular imaging is a core area of PMMR imaging and growing evidence indicates that PMMR is able to detect ischaemic injury at an earlier stage than traditional autopsy and routine histology. The aim of this review is to present an overview of normal findings on forensic PMMR, provide general advice on the application of PMMR and summarise the current literature on PMMR imaging of the head and neck, cardiovascular system, abdomen and musculoskeletal system.

With the rapid growth of positron emission tomography/computed tomography (PET/CT)-based medical applications, body-wide anatomy recognition on whole-body PET/CT images becomes crucial for quantifying body-wide disease burden. This, however, is a challenging problem and seldom studied due to unclear anatomy reference frame and low spatial resolution of PET images as well as low contrast and spatial resolution of the associated low-dose CT images. We previously developed an automatic anatomy recognition (AAR) system [15] whose applicability was demonstrated on diagnostic computed tomography (CT) and magnetic resonance (MR) images in different body regions on 35 objects. The aim of the present work is to investigate strategies for adapting the previous AAR system to low-dose CT and PET images toward automated body-wide disease quantification. Our adaptation of the previous AAR methodology to PET/CT images in this paper focuses on 16 objects in three body regions - thorax, abdomen, and pelvis - and consists of the following steps: collecting whole-body PET/CT images from existing patient image databases, delineating all objects in these images, modifying the previous hierarchical models built from diagnostic CT images to account for differences in appearance in low-dose CT and PET images, automatically locating objects in these images following object hierarchy, and evaluating performance. Our preliminary evaluations indicate that the performance of the AAR approach on low-dose CT images achieves object localization accuracy within about 2 voxels, which is comparable to the accuracies achieved on diagnostic contrast-enhanced CT images. Object recognition on low-dose CT images from PET/CT examinations without requiring diagnostic contrast-enhanced CT seems feasible.

The relationship between body image and depression in women diagnosed with relapsing remitting multiple sclerosis.

Little is known about perceptions of body image in women diagnosed with relapsing remitting multiple sclerosis (RRMS). This descriptive correlational study was conducted to describe how women perceive their body image while living with RRMS, and to examine a potential relationship between body image and depression in women who have RRMS. A convenience sample of 30 women from a western Canadian multiple sclerosis (MS) clinic completed a demographic questionnaire, the Body-Image Ideals Questionnaire (BIQ), and the Beck Depression Inventory Short Form (BDI-SF). Body image and depression scores were highly correlated (r = 0.814, p = 0.01) indicating that a more positive body image was associated with less depression. The findings of this study suggest that there are important psychological aspects to which clinicians might need to attend when working with women who have RRMS. However, further research needs to be done in this area.

2015-06-01

Literature reporting body image disturbances across the perinatal period has produced inconsistent findings, owing to the complexity of body image experiences during pregnancy and the first year postpartum. Existing qualitative data might provide potential avenues to advance understanding of pregnancy-related body image experiences and guide future quantitative research. The present systematic review synthesised the findings of 10 qualitative studies exploring the body image experiences of women through the perinatal period, albeit the majority focused only on pregnancy. Themes emerging included malleability of body image ideals across pregnancy (including the shift from aesthetic to functional concerns about one's appearance), the salience of stomach and breasts for self-rated body satisfaction, and perceived pressure to limit weight gain across pregnancy in order to return quickly to pre-pregnancy figure following birth. These qualitative findings suggest greater complexity of body image experiences during perinatal period than can be captured by typically used self-report measures. Crown Copyright © 2015.

2017-01-01

This study examined the role of media influence and immigration on body image among Pakistani men. Attitudes toward the body were compared between those living in Pakistan (n = 56) and those who had immigrated to the United Arab Emirates (n = 58). Results of a factorial analysis of variance demonstrated a significant main effect of immigrant status. Pakistani men living in the United Arab Emirates displayed poorer body image than those in the Pakistan sample. Results also indicated a second main effect of media influence.Those highly influenced by the media displayed poorer body image. No interaction effect was observed between immigrant status and media influence on body image. These findings suggest that media influence and immigration are among important risk factors for the development of negative body image among non-Western men. Interventions designed to address the negative effects of the media and immigration may be effective at reducing body image disorders and other related health problems in this population.

This study examined the role of media influence and immigration on body image among Pakistani men. Attitudes toward the body were compared between those living in Pakistan ( n = 56) and those who had immigrated to the United Arab Emirates ( n = 58). Results of a factorial analysis of variance demonstrated a significant main effect of immigrant status. Pakistani men living in the United Arab Emirates displayed poorer body image than those in the Pakistan sample. Results also indicated a second main effect of media influence.Those highly influenced by the media displayed poorer body image. No interaction effect was observed between immigrant status and media influence on body image. These findings suggest that media influence and immigration are among important risk factors for the development of negative body image among non-Western men. Interventions designed to address the negative effects of the media and immigration may be effective at reducing body image disorders and other related health problems in this population.

Adolescent Girls and Body Image: Influence of Outdoor Adventure on Healthy Living

The relationship between self-concept and body image was investigated through a secondary analysis of data from a sample of 1,200 high school male students from 30 language/culture communities (Osgood, May, & Myron, 1975). Subjects rated adjectives pertaining to self-concept and body image using 7-step semantic differential bipolar scales. Adjectives were related to the dimensions of Evaluation, Potency, and Activity. Correlation, factor analysis, and multiple regression were utilized to examine multivariate relationships among self-concept dimensions and body-image dimensions. Significant positive correlations were found between self-concept and body image. In addition, significant positive relationships were found when self-concept factors were regressed on the body-image factor (R2 = .49 to .57, p less than or equal to .001) for Activity and Potency. Results support the existence of a strong positive relationship between self-concept and body image across the 30 cultures involved. Findings have important implications for nursing in assessment and interventions with clients who have deficits in either self-concept or body image.

Perceived face size in healthy adults.

D'Amour, Sarah; Harris, Laurence R

2017-01-01

Perceptual body size distortions have traditionally been studied using subjective, qualitative measures that assess only one type of body representation-the conscious body image. Previous research on perceived body size has typically focused on measuring distortions of the entire body and has tended to overlook the face. Here, we present a novel psychophysical method for determining perceived body size that taps into implicit body representation. Using a two-alternative forced choice (2AFC), participants were sequentially shown two life-size images of their own face, viewed upright, upside down, or tilted 90°. In one interval, the width or length dimension was varied, while the other interval contained an undistorted image. Participants reported which image most closely matched their own face. An adaptive staircase adjusted the distorted image to hone in on the image that was equally likely to be judged as matching their perceived face as the accurate image. When viewed upright or upside down, face width was overestimated and length underestimated, whereas perception was accurate for the on-side views. These results provide the first psychophysically robust measurements of how accurately healthy participants perceive the size of their face, revealing distortions of the implicit body representation independent of the conscious body image.

The role of memory in the relationship between attention toward thin-ideal media and body dissatisfaction.

2016-03-01

This study examined the causal relationship between attention and memory bias toward thin-body images, and the indirect effect of attending to thin-body images on women's body dissatisfaction via memory. In a 2 (restrained vs. unrestrained eaters) × 2 (long vs. short exposure) quasi-experimental design, female participants (n = 90) were shown images of thin models for either 7 s or 150 ms, and then completed a measure of body dissatisfaction and a recognition test to assess their memory for the images. Both restrained and unrestrained eaters in the long exposure condition had better recognition memory for images of thin models than did those in the short exposure condition. Better recognition memory for images of thin models was associated with lower body dissatisfaction. Finally, exposure duration to images of thin models had an indirect effect on body dissatisfaction through recognition memory. These findings suggest that memory for body-related information may be more critical in influencing women's body image than merely the exposure itself, and that targeting memory bias might enhance the effectiveness of cognitive bias modification programs.

The current de facto standard for quantification of tumor metabolism in oncological whole-body PET is the standardized uptake value (SUV) approach. SUV determination requires accurate scanner calibration. Residual inaccuracies of the calibration lead to biased SUV values. Especially, this can adversely affect multicenter trials where it is difficult to ensure reliable cross-calibration across participating sites. The goal of the present work was the evaluation of a new method for monitoring scanner calibration utilizing the image-derived arterial blood SUV (BSUV) averaged over a sufficiently large number of whole-body FDG-PET investigations. Data of 681 patients from three sites which underwent routine 18 F-FDG PET/CT or PET/MR were retrospectively analyzed. BSUV was determined in the descending aorta using a three-dimensional ROI concentric to the aorta's centerline. The ROI was delineated in the CT or MRI images and transferred to the PET images. A minimum ROI volume of 5 mL and a concentric safety margin to the aortic wall was observed. Mean BSUV, standard deviation (SD), and standard error of the mean (SE) were computed for three groups of patients at each site, investigated 2 years apart, respectively, with group sizes between 53 and 100 patients. Differences of mean BSUV between the individual groups and sites were determined. SD (SE) of BSUV in the different groups ranged from 14.3 to 20.7% (1.7 to 2.8%). Differences of mean BSUV between intra-site groups were small (1.1-6.3%). Only one out of nine of these differences reached statistical significance. Inter-site differences were distinctly larger (12.6-25.1%) and highly significant (P<0.001). Image-based determination of the group-averaged blood SUV in modestly large groups of whole-body FDG-PET investigations is a viable approach for ensuring consistent scanner calibration over time and across different sites. We propose this approach as a quality control and cross-calibration tool augmenting established phantom-based procedures.

Self-enhancing effects of exposure to thin-body images.

This study examines the effect of thin-body media images on mood, self-esteem, and self-image ratings of restrained and unrestrained eaters. A secondary purpose was to examine whether these effects were influenced by exposure duration. Under the guise of a perception study, participants were exposed to thin-body or control advertisements (e.g., perfume bottles) for either 7 or 150 ms and then completed a questionnaire packet. Restrained eaters reported more favorable self-image and social self-esteem (but not appearance self-esteem) scores after exposure to thin-body images than after exposure to control advertisements. The self-image and social self-esteem scores of unrestrained eaters were unaffected by advertisement type, but their appearance self-esteem scores were lower after exposure to thin-body advertisements. No differences were found for mood ratings and total self-esteem. We discuss restraint status as a moderator of the effects of thin-body images on women's body image.

Cross-sectional pilot study. To explore correlates of body image among women with spinal cord injury (SCI), within the framework of Cash's cognitive behavioral model of body image. Hamilton, Ontario, Canada. Women with SCI (N=11, 64% with tetraplegia) reported their functional and appearance body image (Adult Body Satisfaction Questionnaire). A 3-day recall of leisure time physical activity (LTPA), three measures of body composition (that is, weight, waist circumference, body fat) and several demographic variables were assessed as potential correlates. Appearance satisfaction was negatively correlated with all three measures of body composition and positively correlated with years postinjury. Functional satisfaction was positively correlated with years postinjury, and negatively correlated with various LTPA variables. Functional and appearance body image may improve with time following SCI. Body composition may impact satisfaction with physical appearance for some women. The negative relationship between LTPA and functional satisfaction merits further examination, as functional dissatisfaction may motivate individuals to engage in certain types and intensities of LTPA. Correlates of body image differ between appearance and functional satisfaction. Future research should examine appearance and functional satisfaction separately among women with SCI.

Body image disturbance in adults treated for cancer - a concept analysis.

Rhoten, Bethany A

2016-05-01

To report an analysis of the concept of body image disturbance in adults who have been treated for cancer as a phenomenon of interest to nurses. Although the concept of body image disturbance has been clearly defined in adolescents and adults with eating disorders, adults who have been treated for cancer may also experience body image disturbance. In this context, the concept of body image disturbance has not been clearly defined. Concept analysis. PubMed, Psychological Information Database and Cumulative Index of Nursing and Allied Health Literature were searched for publications from 1937 - 2015. Search terms included body image, cancer, body image disturbance, adult and concept analysis. Walker and Avant's 8-step method of concept analysis was used. The defining attributes of body image disturbance in adults who have been treated for cancer are: (1) self-perception of a change in appearance and displeasure with the change or perceived change in appearance; (2) decline in an area of function; and (3) psychological distress regarding changes in appearance and/or function. This concept analysis provides a foundation for the development of multidimensional assessment tools and interventions to alleviate body image disturbance in this population. A better understanding of body image disturbance in adults treated for cancer will assist nurses and other clinicians in identifying this phenomenon and nurse scientists in developing instruments that accurately measure this condition, along with interventions that will promote a better quality of life for survivors. © 2016 John Wiley & Sons Ltd.

A daily diary study of self-compassion, body image, and eating behavior in female college students.

PubMed

Kelly, Allison C; Stephen, Elizabeth

2016-06-01

Although self-compassion is associated with healthier body image and eating behavior, these findings have generally emerged at the between-persons level only. The present study investigated the unique contributions of within-person variability in self-compassion, and between-persons differences in self-compassion, to body image and eating behavior. Over seven days, 92 female college students completed nightly measures of self-compassion, self-esteem, dietary restraint, intuitive eating, body appreciation, body satisfaction, and state body image. Multilevel modeling revealed that within-persons, day-to-day fluctuations in self-compassion contributed to day-to-day fluctuations in body image and eating. Between-persons, participants' average levels of self-compassion across days contributed to their average levels of body image and eating over the week. Results generally held when controlling for within- and between-persons self-esteem. Evidently, the eating and body image benefits of self-compassion may come not only from being a generally self-compassionate person, but also from treating oneself more self-compassionately than usual on a given day.

This study developed and validated a quantitative measure of body image specifically designed for pregnancy-the Body Image in Pregnancy Scale (BIPS). Scale development was guided by qualitative data from a series of studies exploring the meaning of women's body image experiences during pregnancy, and previously established body image measures. Exploratory factor analysis for a sample of pregnant women (n = 251) indicated good fit for a 36-item scale with seven factors: preoccupation with physical appearance, dissatisfaction with physical strength, dissatisfaction with facial features, sexual attractiveness, prioritizing physical appearance over body functioning, appearance-related behavioral avoidance, and dissatisfaction with body parts. BIPS subscale scores demonstrated good internal reliability, test-retest reliability, and both incremental and convergent validity with measures of body image, self-esteem, and depressive symptomatology. Although the pregnancy-focused wording of BIPS items prevents its use for comparisons with nonpregnant populations, further testing of changes in body image throughout pregnancy is an identified area for further research with this measure.

2013-01-01

The associations between body image and attitudes toward obesity and thinness and their associations with measured body mass index (BMI) among female students of Kuwait University (n = 137) was examined in 2008. The body image perceptions were assessed using nine female silhouettes figures. The difference between current perceived body image (PBI) and ideal body image (IBI) was used as a measure of body image dissatisfaction (BID). Students tended to have a bigger PBI and smaller IBI than would be expected from their BMI category, leading to high levels of BID in each BMI category. PBI, IBI, BID, RBI were highly correlated with each other, and BMI was significantly correlated with each of them. The coefficients of these associations were not significantly altered in multiple regression analysis by the addition of potential confounding variables, such as age, marital status, physical activity, dieting behavior, parental education, and family size. These results suggest that PBI and a desire to be thinner were strongly related to BID and that thinness is becoming more desired in Kuwaiti society than the plump body image of the past.

Treatment for anal and rectal cancer (ARCa) often results in side effects that directly impact sexual functioning; however, ARCa survivors are an understudied group, and factors contributing to the sexual sequelae are not well understood. Body image problems are distressing and may further exacerbate sexual difficulties, particularly for women. This preliminary study sought to (1) describe body image problems, including sociodemographic and disease/treatment correlates, and (2) examine relations between body image and sexual function. For the baseline assessment of a larger study, 70 women completed the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire and Colorectal Cancer-specific Module, including the Body Image subscale, and Female Sexual Function Index. Pearson's correlation and multiple regression evaluated correlates of body image. Among sexually active women (n = 41), hierarchical regression examined relations between body image and sexual function domains. Women were on average 55 years old (standard deviation = 11.6), non-Hispanic White (79%), married (57%), and employed (47%). The majority (86%) reported at least one body image problem. Younger age, lower global health status, and greater severity of symptoms related to poorer body image (p's < 0.05). Poor body image was inversely related to all aspects of sexual function (β range 0.50-0.70, p's < 0.05), except pain. The strongest association was with Female Sexual Function Index Sexual/Relationship Satisfaction. These preliminary findings suggest the importance of assessing body image as a potentially modifiable target to address sexual difficulties in this understudied group. Further longitudinal research is needed to inform the development and implementation of effective interventions to improve the sexual health and well-being of female ARCa survivors.

Body image change and improved eating self-regulation in a weight management intervention in women

PubMed Central

2011-01-01

Background Successful weight management involves the regulation of eating behavior. However, the specific mechanisms underlying its successful regulation remain unclear. This study examined one potential mechanism by testing a model in which improved body image mediated the effects of obesity treatment on eating self-regulation. Further, this study explored the role of different body image components. Methods Participants were 239 overweight women (age: 37.6 ± 7.1 yr; BMI: 31.5 ± 4.1 kg/m2) engaged in a 12-month behavioral weight management program, which included a body image module. Self-reported measures were used to assess evaluative and investment body image, and eating behavior. Measurements occurred at baseline and at 12 months. Baseline-residualized scores were calculated to report change in the dependent variables. The model was tested using partial least squares analysis. Results The model explained 18-44% of the variance in the dependent variables. Treatment significantly improved both body image components, particularly by decreasing its investment component (f2 = .32 vs. f2 = .22). Eating behavior was positively predicted by investment body image change (p < .001) and to a lesser extent by evaluative body image (p < .05). Treatment had significant effects on 12-month eating behavior change, which were fully mediated by investment and partially mediated by evaluative body image (effect ratios: .68 and .22, respectively). Conclusions Results suggest that improving body image, particularly by reducing its salience in one's personal life, might play a role in enhancing eating self-regulation during weight control. Accordingly, future weight loss interventions could benefit from proactively addressing body image-related issues as part of their protocols. PMID:21767360

Current models of beauty represent an extreme thinness in the women and a muscular body in the men. The body image perception will condition the search of ideal beauty through different behaviors and can be transform in eating disorders. The university students, with the changes typical of youth and university transition, are a vulnerable group. The purpose of this study was to evaluate the body image perception of university students in Navarra. The study included 1162 subjects of which 64.2% were female. Students asked for a self-managed questionnaire and they were weighted and heighted to calculate the body mass index (BMI). Their body image perception were obtained asking the students to select a picture, according to their perception which corresponded to their current body image from nine different silhouettes for men and women. Their BMI were calculated and compared with their perceived BMI. 43.03% of students, overestimated their body image (10.65% in males and 59.69% in females) and 10.20% of students underestimated it. 46.75% of students had concordance between BMI and body image perception. There were more cases the alterations in the body image perception in women. In general, women saw themselves as being fatter than really were while men saw themselves as being thinner than they really were. The results shown that the women were more worried about their weight and body image than the men. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Neonicotinoid-induced impairment of odour coding in the honeybee

Andrione, Mara; Vallortigara, Giorgio; Antolini, Renzo; Haase, Albrecht

2016-01-01

Exposure to neonicotinoid pesticides is considered one of the possible causes of honeybee (Apis mellifera) population decline. At sublethal doses, these chemicals have been shown to negatively affect a number of behaviours, including performance of olfactory learning and memory, due to their interference with acetylcholine signalling in the mushroom bodies. Here we provide evidence that neonicotinoids can affect odour coding upstream of the mushroom bodies, in the first odour processing centres of the honeybee brain, i.e. the antennal lobes (ALs). In particular, we investigated the effects of imidacloprid, the most common neonicotinoid, in the AL glomeruli via in vivo two-photon calcium imaging combined with pulsed odour stimulation. Following acute imidacloprid treatment, odour-evoked calcium response amplitude in single glomeruli decreases, and at the network level the representations of different odours are no longer separated. This demonstrates that, under neonicotinoid influence, olfactory information might reach the mushroom bodies in a form that is already incorrect. Thus, some of the impairments in olfactory learning and memory caused by neonicotinoids could, in fact, arise from the disruption in odor coding and olfactory discrimination ability of the honey bees.

MRI in patients with inflammatory bowel disease

Gee, Michael S.; Harisinghani, Mukesh G.

2011-01-01

Inflammatory bowel disease (IBD) affects approximately 1.4 million people in North America and, because of its typical early age of onset and episodic disease course, IBD patients often undergo numerous imaging studies over the course of their lifetimes. CT has become the standard imaging modality for assessment of IBD patients because of its widespread availability, rapid image acquisition, and ability to evaluate intraluminal and extraluminal disease. However, repetitive CT imaging has been associated with a significant ionizing radiation risk to patients, making MRI an appealing alternative IBD imaging modality. Pelvic MRI is currently the imaging gold standard for detecting perianal disease, while recent studies indicate that MRI bowel-directed techniques (enteroclysis, enterography, colonography) can accurately evaluate bowel inflammation in IBD. With recent technical innovations leading to faster and higher resolution body MRI, the role of MRI in IBD evaluation is likely to continue to expand. Future applications include surveillance imaging, detection of mural fibrosis, and early assessment of therapy response. PMID:21512607

Purpose This study aimed to test a group psychosocial intervention focused on improving disturbances of body image (BI), sexual functioning, and quality of life in breast cancer (BC) survivors. Methods A prospective, randomized controlled trial was conducted to assess the efficacy of an 8-week group intervention in women after BC treatment. The manual-based intervention combined two powerful ingredients: expressive guided-imagery exercises integrated within a model of group-therapy principles. The intervention facilitates exploration of identity, the development of new self-schemas, and personal growth. In addition, the intervention included an educational component on the social and cultural factors affecting women's self-esteem and BI. The control condition included standard care plus educational reading materials. One hundred ninety-four BC survivors who had expressed concerns about negative BI and/or difficulties with sexual functioning participated in the study; 131 were randomly assigned to the intervention, and 63 were assigned to the control condition. Participants were followed for 1 year. Results Women in the intervention group reported significantly less concern/distress about body appearance ( P < .01), decreased body stigma ( P < .01), and lower level of BC-related concerns ( P < .01), compared with women in the control group. BC-related quality of life was also better in the intervention group compared with the control group at the 1-year follow-up ( P < .01). There was no statistically significant group difference in sexual functioning. Conclusion Restoring Body Image After Cancer (ReBIC), a group intervention using guided imagery within a group-therapy approach, is an effective method for addressing BI-related concerns and quality of life post-BC. The manual-based intervention can be easily adapted to both cancer centers and primary care settings.

The brain in myotonic dystrophy 1 and 2: evidence for a predominant white matter disease

Myotonic dystrophy types 1 and 2 are progressive multisystemic disorders with potential brain involvement. We compared 22 myotonic dystrophy type 1 and 22 myotonic dystrophy type 2 clinically and neuropsychologically well-characterized patients and a corresponding healthy control group using structural brain magnetic resonance imaging at 3 T (T1/T2/diffusion-weighted). Voxel-based morphometry and diffusion tensor imaging with tract-based spatial statistics were applied for voxel-wise analysis of cerebral grey and white matter affection (Pcorrected < 0.05). We further examined the association of structural brain changes with clinical and neuropsychological data. White matter lesions rated visually were more prevalent and severe in myotonic dystrophy type 1 compared with controls, with frontal white matter most prominently affected in both disorders, and temporal lesions restricted to myotonic dystrophy type 1. Voxel-based morphometry analyses demonstrated extensive white matter involvement in all cerebral lobes, brainstem and corpus callosum in myotonic dystrophy types 1 and 2, while grey matter decrease (cortical areas, thalamus, putamen) was restricted to myotonic dystrophy type 1. Accordingly, we found more prominent white matter affection in myotonic dystrophy type 1 than myotonic dystrophy type 2 by diffusion tensor imaging. Association fibres throughout the whole brain, limbic system fibre tracts, the callosal body and projection fibres (e.g. internal/external capsules) were affected in myotonic dystrophy types 1 and 2. Central motor pathways were exclusively impaired in myotonic dystrophy type 1. We found mild executive and attentional deficits in our patients when neuropsychological tests were corrected for manual motor dysfunctioning. Regression analyses revealed associations of white matter affection with several clinical parameters in both disease entities, but not with neuropsychological performance. We showed that depressed mood and fatigue were more prominent in patients with myotonic dystrophy type 1 with less white matter affection (early disease stages), contrary to patients with myotonic dystrophy type 2. Thus, depression in myotonic dystrophies might be a reactive adjustment disorder rather than a direct consequence of structural brain damage. Associations of white matter affection with age/disease duration as well as patterns of cerebral water diffusion parameters pointed towards an ongoing process of myelin destruction and/or axonal loss in our cross-sectional study design. Our data suggest that both myotonic dystrophy types 1 and 2 are serious white matter diseases with prominent callosal body and limbic system affection. White matter changes dominated the extent of grey matter changes, which might argue against Wallerian degeneration as the major cause of white matter affection in myotonic dystrophies. PMID:22131273

(1) To investigate the course of body image in patients with spinal cord injury (SCI) during their first inpatient rehabilitation stay; and (2) to explore the association between demographic and injury-related variables and body image and the association between body image and psychological distress. Longitudinal inception cohort study. Rehabilitation center. Of the 210 people admitted for their first inpatient SCI rehabilitation program (between March 2011 and April 2015), 188 met the inclusion criteria. Of these, N=150 (80%) agreed to participate. Not applicable. The Body Experience Questionnaire was used to measure 2 dimensions of body image: alienation and harmony. Mean scores on the Body Experience Questionnaire alienation subscale decreased significantly during the rehabilitation program. Mean scores on the Body Experience Questionnaire harmony subscale did not increase significantly but showed a trend in the hypothesized direction. The 2 subscales showed weak correlations with demographic and injury-related variables. The 2 subscales together explained 16% and 14% of the variance of depression and anxiety, respectively, after correction for demographic and injury-related variables. During participants' first inpatient rehabilitation stay after SCI, body image progressed toward a healthier state. Body image explains part of the variance in depression and anxiety, and the entire rehabilitation team should be targeting interventions to improve body image.

To analyse the scientific literature regarding the evaluation of body image in children through an integrative literature review. An intersection of the keywords "body image" AND "child" was conducted in Scopus, Medline and Virtual Health Library (BVS - Biblioteca Virtual de Saúde) databases. The electronic search was based on studies published from January 2013 to January 2016, in order to verify the most current investigations on the subject. Exclusion criteria were: articles in duplicate; no available summaries; not empirical; not assessing any component of body image; the sample did not consider the target age of this research (0 to 12 years old) and/or considered clinical populations; besides articles not fully available. 7,681 references were identified, and, after the exclusion criteria were implemented, 33 studies were analysed. Results showed that the perceptual and attitudinal dimensions focusing on body dissatisfaction were explored, mainly evaluated by silhouette scales. Intervention programs were developed internationally to prevent negative body image in children. The studies included in this review evaluated specific aspects of body image in children, especially body perception and body dissatisfaction. The creation of specific tools for children to evaluate body image is recommended to promote the psychosocial well being of individuals throughout human development.

Body category-selective regions of the primate temporal cortex respond to images of bodies, but it is unclear which fragments of such images drive single neurons' responses in these regions. Here we applied the Bubbles technique to the responses of single macaque middle superior temporal sulcus (midSTS) body patch neurons to reveal the image fragments the neurons respond to. We found that local image fragments such as extremities (limbs), curved boundaries, and parts of the torso drove the large majority of neurons. Bubbles revealed the whole body in only a few neurons. Neurons coded the features in a manner that was tolerant to translation and scale changes. Most image fragments were excitatory but for a few neurons both inhibitory and excitatory fragments (opponent coding) were present in the same image. The fragments we reveal here in the body patch with Bubbles differ from those suggested in previous studies of face-selective neurons in face patches. Together, our data indicate that the majority of body patch neurons respond to local image fragments that occur frequently, but not exclusively, in bodies, with a coding that is tolerant to translation and scale. Overall, the data suggest that the body category selectivity of the midSTS body patch depends more on the feature statistics of bodies (e.g., extensions occur more frequently in bodies) than on semantics (bodies as an abstract category).

2015-06-01

Although body image is central to the etiological models of anorexia nervosa and body dysmorphic disorder, studies comparing body image and beliefs about attractiveness between the disorders are rare. Sixty-nine individuals (anorexia nervosa: n=24, body dysmorphic disorder: n=23, healthy controls: n=22) completed self-report measures (body image and general psychopathology), diagnostic interviews, and Go/No-Go Association tasks measuring implicit associations. Compared to controls, both clinical groups exhibited greater negative body image, a more negative attitude toward their physical selves, and more dysfunctional coping strategies (ps<.001). Also, both clinical groups shared greater explicit beliefs about the importance of attractiveness (ps<.001). In addition to supporting previous research with regard to comparable body image disturbance, this study also showed that beliefs regarding the importance of appearance (e.g., "one must be attractive to be successful") might be a fruitful target for therapy across both disorders.

Sketching people: Prospective investigations of the impact of life drawing on body image.

Swami, Viren

2017-03-01

Three studies were conducted to establish the extent to which life drawing is effective at promoting positive body image. Study 1 (N=84 women) showed that life drawing had a positive impact on state body image, but only if artists observed a human model and not non-human objects. Study 2 (N=61 women, 61 men) showed that life drawing had a positive impact on state body image for women and men, irrespective of whether artists observed a sex-congruent or -incongruent model. Study 3 (N=23) showed that participating in weekly life drawing sessions for a 6-week period resulted in significantly elevated trait positive body image (body appreciation and body pride) and embodiment, and in reduced social physique anxiety; however, the intervention had no significant impact on negative body image (drive for thinness or muscularity). These results highlight the potential of life drawing for promoting positive body experiences. Copyright © 2016 Elsevier Ltd. All rights reserved.

Differences in neural activation to depictions of physical exercise and sedentary activity: an fMRI study of overweight and lean Chinese women.

2014-09-01

Neuroimaging studies have documented differences in neural responses to food cues in obese versus lean samples but little is known about weight status differences in responsiveness to other key features of obesogenic environments, particularly cues reflecting physical activity. To address this gap, patterns of activation related to visual depictions of sedentary activities and vigorous physical exercise were assessed in overweight (O-W) and average weight (A-W) samples via functional magnetic resonance imaging (fMRI). Thirteen O-W and 13 A-W Chinese women were instructed to imagine engaging in 90 physical exercise activities and 90 sedentary activities and to watch 90 landscape images presented during three runs of an fMRI scan within a cross-sectional design. Behavioral results indicated O-W women endorsed more negative attitudes toward physical activity than A-W did. Imaging analyses indicated that body mass index had a significant negative association with activation of the right putamen and a positive correlation with activation in the right medial frontal gyrus, specifically Brodmann Area 10 in the exercise-sedentary image contrast condition. For the sedentary-control contrast, significantly less activation in an insula area related to negative affect was observed for the O-W group. Finally, for the exercise-control contrast, O-W women also displayed comparatively weaker activation in a cingulate gyrus area implicated in kinesthetic memory of body movements and the re-experiencing real events. Together, results supported contentions that exposure to depictions of physical exercise corresponds to reduced activation of reward centers and heightened activation in regions associated with negative affect regulation among O-W women compared with leaner peers.

Emotional distress and disordered eating practices among southern Italian women.

Cheney, Ann M

2012-09-01

This study is one of the first to examine the narrative links connecting social change, contested gender norms, body image, and eating disordered practices among southern Italian women. The research is based on 16 months of fieldwork, and I compare and contrast the stories of 23 educated women in southern Italy to highlight the contentious realities of entering adolescence in conservative social contexts where gender relations and value systems are undergoing rapid transformations. I examine how these young women dealt with conflicting cultural expectations of womanhood and whether it affected their emotional, psychological, and physical well-being. Their stories shed light on how parental control, community surveillance, and conflicts in developing gender identities and maturing womanly bodies contributed to their emotional distress. Distressed young women used rebellion and manipulation and control of food and the body to negotiate unjust social relations, specifically gender relations, that delegitimized their selves and, in some cases, their bodies.

#fitspo or #loveyourself? The impact of fitspiration and self-compassion Instagram images on women's body image, self-compassion, and mood.

Slater, Amy; Varsani, Neesha; Diedrichs, Phillippa C

2017-09-01

This study experimentally examined the impact of exposure to fitspiration images and self-compassion quotes on social media on young women's body satisfaction, body appreciation, self-compassion, and negative mood. Female undergraduate students (N=160) were randomly assigned to view either Instagram images of fitspiration, self-compassion quotes, a combination of both, or appearance-neutral images. Results showed no differences between viewing fitspiration images compared to viewing neutral images, except for poorer self-compassion among those who viewed fitspiration images. However, women who viewed self-compassion quotes showed greater body satisfaction, body appreciation, self-compassion, and reduced negative mood compared to women who viewed neutral images. Further, viewing a combination of fitspiration images and self-compassion quotes led to positive outcomes compared to viewing only fitspiration images. Trait levels of thin-ideal internalisation moderated some effects. The findings suggest that self-compassion might offer a novel avenue for attenuating the negative impact of social media on women's body satisfaction. Copyright © 2017 Elsevier Ltd.

Anorexia nervosa (AN) is a severe mental illness, which is characterized by a continuously growing occurrence in the population and by the shift of the onset for earlier ages. The understanding of factors playing role in AN and the importance of effective prevention is an essential issue in science as well as in the society. AN also affects the social domain of life, patients with AN may exhibit impaired social interaction, social isolation, difficulties in emotion recognition and egocentric thinking in cognitive processing. Therefore, the aim of present study was to investigate the theory of mind (ToM) deficits is anorexia nervosa. Although previous studies have reported ToM deficits in autism and in schizophrenia, the number of studies investigating ToM functioning in eating disorders are particularly low. Even though ToM difficulties, such as the affective ToM impairments were found in AN, however, the evidence of cognitive ToM deficits in anorexia patients is still lacking. Twenty anorexia nervosa patients and 20 healthy control adolescent girls participated in the experiment. EDI, BAT, Fallon-Rozin Test and Anamoprhic Micro Body Image Assesment Programme questionnaires and body-image tests were applied to discriminate anorexia nervosa group from healthy control group. The Hungarian version of Faux Pas Recognition Test was applied to evaluate ToM functioning. Compared to healthy control group, impairment in ToM functioning was found in AN group, especially in affective mental state attribution. Our results can raise new aspects for research, therapy and prevention of anorexia nervosa.

Limited research exists on muscle dysmorphia (MD) in men and in nonclinical populations. The current study evaluated types of body image disturbance among 237 male weightlifters. Latent class analysis of 8 measures of body image disturbance revealed 5 independent types of respondents: Dysmorphic, Muscle Concerned, Fat Concerned, Normal Behavioral, and Normal. One-way analysis of variance of independent measures of body image disturbance and associated psychopathology confirmed significant differences between groups. The Dysmorphic group reported a pattern of body image disturbance consistent with MD by displaying a high overall level of body image disturbance, symptoms of associated psychopathology, steroid use, and appearance-controlling behavior. Findings generally supported classifying MD as a subtype of body dysmorphic disorder and an obsessive-compulsive spectrum disorder. Implications for studying body image disturbance in male weightlifters, and further evaluation of the MD diagnostic criteria are discussed.

Eating disorders awareness week: the effectiveness of a one-time body image dissatisfaction prevention session.

PubMed

Ridolfi, Danielle R; Vander Wal, Jillion S

2008-01-01

The purpose of this study was to assess the effectiveness of a body image dissatisfaction prevention session that provided information on body image and media literacy to college women. Participants were 81 undergraduates who were randomly assigned to attend either a body image intervention or a control intervention. Participants completed measures at pre- and post-intervention and at 4-week follow-up. The body image group improved significantly more than the control group on body shape concerns, but not on the other outcome variables. Efficacious interventions capable of reaching large numbers of women are necessary to help dispel the "normative discontent" prevalent today.

South African studies have suggested that differences in obesity prevalence between groups may be partly related to differences in body image and body size dissatisfaction. However, there has never been a national study that measured body image and its relationship to weight control in the country. Hence, the main aim of the study was to examine body image in relation to body mass index and weight control in South Africa. A cross-sectional survey and a secondary analyses of data were undertaken for 6 411 South Africans (15+ years) participating in the first South African National Health and Nutrition Examination Survey. Body image was investigated in relation to weight status and attempts to lose or gain weight. Data were analysed using STATA version 11.0. Descriptive statistics are presented as counts (numbers), percentages, means, standard error of means, and 95 % confidence intervals. Any differences in values were considered to be significantly different if the confidence intervals did not overlap. Overall, 84.5 % participants had a largely distorted body image and 45.3 % were highly dissatisfied about their body size. Overweight and obese participants under estimated their body size and desired to be thinner. On the other hand, normal- and under-weight participants over estimated their body size and desired to be fatter. Only 12.1 and 10.1 % of participants attempted to lose or gain weight, respectively, mainly by adjusting dietary intake and physical activity. Body mass index appears to influence body image and weight adjustment in South Africa. South Africans at the extreme ends of the body mass index range have a largely distorted body image and are highly dissatisfied by it. This suggests a need for health education and beneficial weight control strategies to halt the obesity epidemic in the country.

Focusing on body functionality is a promising technique for improving women's body image. This study replicates prior research in a large novel sample, tests longer-term follow-up effects, and investigates underlying mechanisms of these effects (body complexity and body-self integration). British women (N = 261) aged 18-30 who wanted to improve their body image were randomised to Expand Your Horizon (three online body functionality writing exercises) or an active control. Trait body image was assessed at Pretest, Posttest, 1-week, and 1-month Follow-Up. To explore whether changes in body complexity and body-self integration 'buffer' the impact of negative body-related experiences, participants also completed beauty-ideal media exposure. Relative to the control, intervention participants experienced improved appearance satisfaction, functionality satisfaction, body appreciation, and body complexity at Posttest, and at both Follow-Ups. Neither body complexity nor body-self integration mediated intervention effects. Media exposure decreased state body satisfaction among intervention and control participants, but neither body complexity nor body-self integration moderated these effects. The findings underscore the value of focusing on body functionality for improving body image and show that effects persist one month post-intervention. Copyright © 2018 Elsevier Ltd.

"Exercise to be fit, not skinny": The effect of fitspiration imagery on women's body image.

PubMed

Tiggemann, Marika; Zaccardo, Mia

2015-09-01

Fitspiration is an online trend designed to inspire viewers towards a healthier lifestyle by promoting exercise and healthy food. The present study aimed to experimentally investigate the impact of fitspiration images on women's body image. Participants were 130 female undergraduate students who were randomly assigned to view either a set of Instagram fitspiration images or a control set of travel images presented on an iPad. Results showed that acute exposure to fitspiration images led to increased negative mood and body dissatisfaction and decreased state appearance self-esteem relative to travel images. Importantly, regression analyses showed that the effects of image type were mediated by state appearance comparison. Thus it was concluded that fitspiration can have negative unintended consequences for body image. The results offer support to general sociocultural models of media effects on body image, and extend these to "new" media. Copyright © 2015 Elsevier Ltd. All rights reserved.

Anthropometric measurements, such as the circumferences of the hip, arm, leg and waist, waist-to-hip ratio, and body mass index, are of high significance in obesity and fitness evaluation. In this paper, we present a home based imaging system capable of conducting anthropometric measurements. Body images are acquired at different angles using a home camera and a simple rotating disk. Advanced image processing algorithms are utilized for 3D body surface reconstruction. A coarse body shape model is first established from segmented body silhouettes. Then, this model is refined through an inter-image consistency maximization process based on an energy function. Our experimental results using both a mannequin surrogate and a real human body validate the feasibility of the proposed system.

This study examined the importance of body image evaluation and investment to predict dietary restraint in men (N = 272). Measures of physical activity, evaluation, investment and dietary restraint were completed. A hierarchical regression was conducted to predict dietary restraint from physical activity and body mass index (entered on the first step), body image evaluation (entered on the second step) and investment (entered on the final step). The overall regression was significant, F(4, 271) = 15.12, p < .001, R (2) adj = .17). Body mass index, physical activity and body image investment were significant positive predictors of dietary restraint. The present findings emphasize measuring body image investment. © The Author(s) 2015.

Segmentation of skin lesions in chronic graft versus host disease photographs with fully convolutional networks

Chronic graft-versus-host disease (cGVHD) is a frequent and potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HCT) and commonly affects the skin, resulting in distressing patient morbidity. The percentage of involved body surface area (BSA) is commonly used for diagnosing and scoring the severity of cGVHD. However, the segmentation of the involved BSA from patient whole body serial photography is challenging because (1) it is difficult to design traditional segmentation method that rely on hand crafted features as the appearance of cGVHD lesions can be drastically different from patient to patient; (2) to the best of our knowledge, currently there is no publicavailable labelled image set of cGVHD skin for training deep networks to segment the involved BSA. In this preliminary study we create a small labelled image set of skin cGVHD, and we explore the possibility to use a fully convolutional neural network (FCN) to segment the skin lesion in the images. We use a commercial stereoscopic Vectra H1 camera (Canfield Scientific) to acquire 400 3D photographs of 17 cGVHD patients aged between 22 and 72. A rotational data augmentation process is then applied, which rotates the 3D photos through 10 predefined angles, producing one 2D projection image at each position. This results in 4000 2D images that constitute our cGVHD image set. A FCN model is trained and tested using our images. We show that our method achieves encouraging results for segmenting cGVHD skin lesion in photographic images.

Understanding Appearance-Enhancing Drug Use in Sport Using an Enactive Approach to Body Image

PubMed Central

Hauw, Denis; Bilard, Jean

2017-01-01

From an enactive approach to human activity, we suggest that the use of appearance-enhancing drugs is better explained by the sense-making related to body image rather than the cognitive evaluation of social norms about appearance and consequent psychopathology-oriented approach. After reviewing the main psychological disorders thought to link body image issues to the use of appearance-enhancing substances, we sketch a flexible, dynamic and embedded account of body image defined as the individual’s propensity to act and experience in specific situations. We show how this enacted body image is a complex process of sense-making that people engage in when they are trying to adapt to specific situations. These adaptations of the enacted body image require effort, perseverance and time, and therefore any substance that accelerates this process appears to be an easy and attractive solution. In this enactive account of body image, we underline that the link between the enacted body image and substance use is also anchored in the history of the body’s previous interactions with the world. This emerges during periods of upheaval and hardship, especially in a context where athletes experience weak participatory sense-making in a sport community. We conclude by suggesting prevention and intervention designs that would promote a safe instrumental use of the body in sports and psychological helping procedures for athletes experiencing difficulties with substances use and body image.

2017-01-01

Although exposure to physique-salient media images of women's bodies has been consistently linked with negative psychological consequences, little is known about the cognitive processes that lead to these negative effects. The present study employed a novel adaptation of a computerized response time (RT) task to (i) assess implicit cognitive processing when exposed to the body of another individual, and (ii) examine individual differences in social comparative emotions that may influence the cognitive processing of human bodies. Adult females with low (n = 44) or high (n = 23) tendencies for comparative emotions completed a task in which they executed responses to coloured targets presented on the hands or feet of images of ultra-thin, average-size, and above average-size female models. Although the colour of the target is the only relevant target feature, it is typically found that the to-be-ignored location of the target on the body of the model influences RTs such that RTs are shorter when the target is on a body-part that is compatible with the responding limb (e.g., hand response when target was on hand) than on a body-part that is incompatible with the responding limb (e.g., hand response when target was on foot). Findings from the present study revealed that the magnitude of the body-part compatibility effect (i.e., the index of the cognitive processing of the model) was modulated by tendencies for affective body-related comparisons. Specifically, women who were prone to experiencing social comparative emotions demonstrated stronger and more consistent body-part compatibility effects across models. Therefore, women with higher social comparison tendencies have heightened processing of bodies at a neurocognitive level and may be at higher risk of the negative outcomes linked with physique-salient media exposure.

Roles of body image-related experiential avoidance and uncommitted living in the link between body image and women's quality of life.

2018-01-01

The current study aimed to test whether the associations of body mass index, body image discrepancy, and social comparison based on physical appearance with women's psychological quality of life (QoL) would be explained by the mechanisms of body image-related experiential avoidance and patterns of uncommitted living. The sample was collected from October 2014 to March 2015 and included 737 female college students (aged between 18 and 25 years) who completed validated self-report measures. Results demonstrated that the final path model explained 43% of psychological QoL and revealed an excellent fit. Body image-related experiential avoidance had a meditational role in the association between body image discrepancy and psychological QoL. Further, the link between social comparison based on physical appearance and psychological QoL was partially mediated by body image-related experiential avoidance and uncommitted living. These findings indicate that the key mechanisms of the relationship between body image and young women's QoL were those related to maladaptive emotion regulation. It thus seems that interventions aiming to promote mental health in this population should promote acceptance of internal experiences related to physical appearance (e.g., sensations, thoughts, or emotions) and the engagement in behaviors committed to life values.

Sánchez-Carracedo, David; Carretero, Cristina; Conesa, Alfons

2017-04-01

The field of prevention of body image problems and eating disorders has made major advances in recent years, particularly in the development and evaluation of prevention programmes. However, few programmes achieve good long-term results because, among other reasons, the sociocultural influences affecting the development of these problems do not stop. Moreover, accelerating progress in this field is required, transferring their impact onto a larger scale. These reasons justify the need to progress in the development of public policy interventions. This paper describes a recent Catalan initiative in this sphere: the Roundtable on the Prevention of Eating Disorders, made up of different public and private sectors of Catalan society. It specifically details the main actions carried out, such as: media campaigns to reduce weight-related teasing and encouraging self-esteem, encouraging family meals and promoting help-seeking among those affected; the creation of a new informative website about these matters in the Department of Health; the production of a Decalogue of Best Practices for the promotion of self-esteem and positive body image in social media and advertising; and actions to prevent the promotion of eating disorders on the Internet. The Roundtable is the most comprehensive Catalan (and Spanish) public policy activity undertaken until now for the prevention of eating disorders. Copyright © 2016 Elsevier Ltd. All rights reserved.

Psychological factors and trimester-specific gestational weight gain: a systematic review.

2015-01-01

Excess gestational weight gain (GWG), which has reached epidemic proportions, is associated with numerous adverse pregnancy outcomes. Early pregnancy provides a unique opportunity for counseling pregnant women since many women are motivated to engage in healthy behaviors. A systematic review was conducted to summarize the relation between psychological factors and trimester-specific GWG, i.e. GWG measured at the end of each trimester. Eight databases were searched for affect, cognition and personality factors. The guidelines on meta-analysis of Observational Studies in Epidemiology were followed. The methodological quality of each study was assessed using a modified Newcastle-Ottawa Scale. Of 3620 non-duplicate titles and abstracts, 74 articles underwent full-text review. Two cohort studies met the inclusion criteria. Distress was negatively associated with first trimester GWG among both adolescents and non-adolescents. Body image dissatisfaction was associated with second trimester GWG only among non-adolescents. No association emerged between perceived stress, state and trait anxiety and body image dissatisfaction among adolescents and trimester-specific GWG. The relation between trimester-specific GWG and a number of weight-related and dietary-related cognitions, affective states and personality traits remain unexplored. Given the limited number of studies, further high-quality evidence is required to examine the association between psychological factors and trimester-specific GWG, especially for cognitive and personality factors.

The purpose of the current study was to assess the uniqueness of the condition of kidney transplant recipients in comparison to a sample of matching healthy peers in relation to body-image dissatisfaction and identification, quality of life and psychological distress. Participants were 45 kidney transplant recipients who were under follow-up care at a Transplant Unit of a major Medical Center, and a sample of 45 matching healthy peers. Measures were taken using self-report questionnaires [Body-Image Ideals Questionnaire (BIIQ), Body Identification Questionnaire (BIQ), Brief Symptoms Inventory (BSI), and the SF-12]. The major findings were the following: (i) kidney transplant recipients reported lower levels of quality of life and higher levels of PsD when compared to their healthy peers; (ii) no difference in body-image dissatisfaction was found between the two studied groups; (iii) significant correlations between body-image dissatisfaction quality of life and PsD were found only in the kidney transplant recipients. The kidney transplantation condition has a moderating effect in the association between body-image dissatisfaction PsD but not in the association between body-image dissatisfaction and quality of life; (iv) kidney transplant recipients experienced higher levels of body identification than did their healthy peers. Taken together, these findings highlight the unique condition of kidney transplant recipients, as well as the function that body-image plays within the self.

The current study examined body image concerns among African American women. In recent years, there has been an attempt to include ethnic minority samples in body image studies (e.g., Grabe & Hyde, 2006; Hrabosky & Grilo, 2007; Lovejoy, 2001) but few specifically examine unique issues pertaining to beauty and body image for African American college age women. A total of 31 African American women participated in one of five focus groups on the campus of a large Southwestern University to examine beauty and body image. Data were analyzed using a thematic approach and several themes were identified. The majority of themes pertained to issues related to hair, skin tone, body type, and message sources. Themes included: sacrifice, ignorance/racial microaggressions, and validation and invalidation by others, thick/toned/curvy as optimal, hypersexualization, and being thin is for White women. Findings of the current study suggest a reconceptualization of body image for African American women where relevant characteristics such as hair and skin tone are given more priority over traditional body image concerns often associated with European American women.

To date, various dimensions of body image and their associations with condom use have not been studied among men who have sex with men (MSM) who use geosocial-networking smartphone applications ("apps") to meet new sexual partners. The purpose of the current study was to evaluate associations between weight perception, body dissatisfaction, and self-objectification with sexual behaviors among a sample of MSM (N = 92) recruited from Grindr, an app popular among MSM, to complete an online survey. Obese participants scored significantly higher on measures of body dissatisfaction and lower on measures of sexual sensation seeking. Decreased propensities to seek sexual sensations were associated with fewer sexual partners. By assessing associations between dimensions of body dissatisfaction and sexual risk behaviors, this study adds support to a theory of syndemics among MSM, which suggests that synergistically related biological, psychological, social, and behavioral factors disproportionately affect health and health-related behaviors in this population.

Disclaimer labels on fashion magazine advertisements: Impact on visual attention and relationship with body dissatisfaction.

PubMed

Bury, Belinda; Tiggemann, Marika; Slater, Amy

2016-03-01

Globally there is increasing advocacy for the implementation of laws requiring disclaimer labels to be attached to media images that have been digitally altered, with the goal of reducing the known negative effects of exposure to unrealistic thin ideal imagery for women. The current study used eye tracking technology to establish how digital alteration disclaimer labels affect women's visual attention to fashion magazine advertisements, and the interrelationship with body dissatisfaction and state appearance comparison. Participants were 120 female undergraduate students who viewed four thin ideal advertisements with either no disclaimer, a generic disclaimer, or a more detailed specific disclaimer. It was found that women did attend to the disclaimers. Specifically worded disclaimers directed visual attention towards target body areas, which resulted in increased body dissatisfaction, while state appearance comparison predicted increased body dissatisfaction. Further research is imperative to provide guidance on the most effective use of disclaimer labels. Copyright © 2015 Elsevier Ltd. All rights reserved.

Emotion regulation moderates relationships between body image concerns and psychological symptomatology.

PubMed

Hughes, Elizabeth K; Gullone, Eleonora

2011-06-01

The study investigated the moderating role of emotion regulation (ER) in relationships between body image concerns and psychological symptomatology. A community sample of 533 boys and girls (11-20 years) completed measures assessing body image thoughts and feelings, domain-specific and general ER strategies, drive for thinness, and bulimic, depressive and anxiety symptoms. Results indicated that ER moderated relationships between body image concerns and both bulimic and depressive symptoms, but not relationships between body image concerns and drive for thinness or anxiety symptoms. Adolescents who reported frequent body image concerns were more likely to have higher levels of bulimic symptoms if they tended to use avoidance and internal dysfunctional ER strategies. Furthermore, adolescents who reported frequent body image concerns were more likely to have higher levels of depressive symptoms if they used positive rational acceptance and internal functional strategies infrequently. Implications of the findings for prevention and intervention are discussed. Copyright © 2011 Elsevier Ltd. All rights reserved.

The longitudinal causal directionality between body image distress and self-esteem among Korean adolescents: the moderating effect of relationships with parents.

PubMed

Park, Woochul; Epstein, Norman B

2013-04-01

This study examined the longitudinal relationship between self-esteem and body image distress, as well as the moderating effect of relationships with parents, among adolescents in Korea, using nationally representative prospective panel data. Regarding causal direction, the findings supported bi-directionality for girls, but for boys the association was unidirectional, in that their self-esteem predicted body image distress, but not vice versa. A gender difference also emerged in the moderating effect of quality of relationships with parents. For girls, relationships with parents moderated the effect of body image distress on self-esteem, such that when relationships with parents were better, the effect of greater body image distress on subsequent lower self-esteem was stronger than when relationships with parents were less positive. For boys, relationships with parents moderated the influence of self-esteem on body image distress, such that self-esteem reduced body image distress more when boys had better relationships with parents.

Background Obesity has adverse physical, social, and economic consequences that can negatively affect quality of life (QOL). Thus the aim of this study was to verify the effects of a long-term multidisciplinary lifestyle intervention on QOL, body image, anxiety, depression and binge eating in obese adolescents. Methods Sixty-six obese adolescents (41 girls and 25 boys; BMI: 35.62 ± 4.18 kg/m2) were recruited from the Multidisciplinary Obesity Intervention Program outpatient clinic, and were submitted to a multidisciplinary lifestyle therapy (short-term = 12 weeks and long-term = 24 weeks), composed of medical, dietary, exercise and psychological programs. Validated self-report questionnaires were used to assess symptoms of anxiety Trait/State (STAI); depression (BDI); binge eating (BES), body image dissatisfaction (BSQ) and QOL (SF-36). Data were analyzed by means of scores; comparisons were made by ANOVA for repeated measures, and Tukey's test as post-hoc and Students T test. Results Long-term therapy decreased depression and binge eating symptoms, body image dissatisfaction, and improved QOL in girls, whereas, for boys, 24 weeks, were effective to reduce anxiety trait/state and symptoms of binge eating, and to improve means of dimensions of QOL (p < .05). Conclusion A long-term multidisciplinary lifestyle therapy is effective to control psychological aspects and to improve QOL in obese adolescents. PMID:19575801

To study the determinants of image quality of rotational angiography using dedicated research prototype software for motion compensation without rapid ventricular pacing after the implantation of four commercially available catheter-based valves. Prospective observational study including 179 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) with either the Medtronic CoreValve (MCS), Edward-SAPIEN Valve (ESV), Boston Sadra Lotus (BSL) or Saint-Jude Portico Valve (SJP) in whom rotational angiography (R-angio) with motion compensation 3D image reconstruction was performed. Image quality was evaluated from grade 1 (excellent image quality) to grade 5 (strongly degraded). Distinction was made between good (grades 1, 2) and poor image quality (grades 3-5). Clinical (gender, body mass index, Agatston score, heart rate and rhythm, artifacts), procedural (valve type) and technical variables (isocentricity) were related with the image quality assessment. Image quality was good in 128 (72 %) and poor in 51 (28 %) patients. By univariable analysis only valve type (BSL) and the presence of an artefact negatively affected image quality. By multivariate analysis (in which BMI was forced into the model) BSL valve (Odds 3.5, 95 % CI [1.3-9.6], p = 0.02), presence of an artifact (Odds 2.5, 95 % CI [1.2-5.4], p = 0.02) and BMI (Odds 1.1, 95 % CI [1.0-1.2], p = 0.04) were independent predictors of poor image quality. Rotational angiography with motion compensation 3D image reconstruction using a dedicated research prototype software offers good image quality for the evaluation of frame geometry after TAVI in the majority of patients. Valve type, presence of artifacts and higher BMI negatively affect image quality.

To test the reliability of the Children's Body Image Scale (CBIS) and assess its usefulness in the context of new body size charts for children. Participants were 281 primary schoolchildren with 50% being retested after 3 weeks. The CBIS figure scale was compared with a range of international body mass index (BMI) reference standards. Children had a high degree of body image dissatisfaction. The test-retest reliability of the CBIS was supported. The CBIS is a useful tool for assessing body image in children with sound scale properties. It can also be used to identify the body size of children, which lies outside the healthy weight range of BMI.

Asymptomatic traumatic intra-lenticular foreign body is very uncommon and few case reports have been published. To report a case of post-traumatic intra-lenticular foreign body and use of Scheimpflug imaging in its management. A 41-year-old male with history of injury to right eye during hammering a chisel 1 year back presented with decreased vision since 6 months. An intra-lenticular foreign body was found on slit lamp bio-microscopy and was confrmed by Scheimpflug imaging. Posterior capsule was intact on Scheimpflug imaging. Thus, Scheimpflug imaging helps in exact localization of the foreign body in the intralenticular space or behind the iris. We ruled out other foreign bodies by x-ray and ultrasonography of the orbit. The foreign body with post-traumatic cataract was removed using phacoemulsification and three piece foldable intraocular lens was implanted in the bag. An intra- lenticular foreign body may remain asymptomatic for months. Scheimpflug imaging can be useful in its localization. It can be removed during phacoemulsification. © NEPjOPH.

The relationship between Facebook and Instagram appearance-focused activities and body image concerns in young women.

Cohen, Rachel; Newton-John, Toby; Slater, Amy

2017-12-01

The present study aimed to identify the specific social networking sites (SNS) features that relate to body image concerns in young women. A total of 259 women aged 18-29years completed questionnaire measures of SNS use (Facebook and Instagram) and body image concerns. It was found that appearance-focused SNS use, rather than overall SNS use, was related to body image concerns in young women. Specifically, greater engagement in photo activities on Facebook, but not general Facebook use, was associated with greater thin-ideal internalisation and body surveillance. Similarly, following appearance-focused accounts on Instagram was associated with thin-ideal internalisation, body surveillance, and drive for thinness, whereas following appearance-neutral accounts was not associated with any body image outcomes. Implications for future SNS research, as well as for body image and disordered eating interventions for young women, are discussed. Crown Copyright © 2017. Published by Elsevier Ltd.

Kelly, Allison C; Vimalakanthan, Kiruthiha; Miller, Kathryn E

2014-09-01

The current study examined whether self-compassion, the tendency to treat oneself kindly during distress and disappointments, would attenuate the positive relationship between body mass index (BMI) and eating disorder pathology, and the negative relationship between BMI and body image flexibility. One-hundred and fifty-three female undergraduate students completed measures of self-compassion, self-esteem, eating disorder pathology, and body image flexibility, which refers to one's acceptance of negative body image experiences. Controlling for self-esteem, hierarchical regressions revealed that self-compassion moderated the relationships between BMI and the criteria. Specifically, the positive relationship between BMI and eating disorder pathology and the negative relationship between BMI and body image flexibility were weaker the higher women's levels of self-compassion. Among young women, self-compassion may help to protect against the greater eating disturbances that coincide with a higher BMI, and may facilitate the positive body image experiences that tend to be lower the higher one's BMI.

Form or function: Does focusing on body functionality protect women from body dissatisfaction when viewing media images?

PubMed

Mulgrew, Kate E; Tiggemann, Marika

2018-01-01

We examined whether shifting young women's ( N =322) attention toward functionality components of media-portrayed idealized images would protect against body dissatisfaction. Image type was manipulated via images of models in either an objectified body-as-object form or active body-as-process form; viewing focus was manipulated via questions about the appearance or functionality of the models. Social comparison was examined as a moderator. Negative outcomes were most pronounced within the process-related conditions (body-as-process images or functionality viewing focus) and for women who reported greater functionality comparison. Results suggest that functionality-based depictions, reflections, and comparisons may actually produce worse outcomes than those based on appearance.

Skin surface temperature of broiler chickens is correlated to body core temperature and is indicative of their thermoregulatory status.

Giloh, M; Shinder, D; Yahav, S

2012-01-01

Extreme thermal conditions may dramatically affect the performance of broilers and other domestic animals, thereby impairing animal welfare and causing economic losses. Although body core temperature is the parameter that best reflects a bird's thermal status, practical and physiological obstacles make it irrelevant as a source of information on the thermal status of commercial flocks. Advances in the technology of infrared thermal imaging have enabled highly accurate, noncontact, and noninvasive measurements of skin surface temperature. Providing that skin surface temperature correlates with body temperature, this technology could enable acquisition of reliable information on the thermal status of animals, thereby improving diagnoses of environmental stress in a flock. This study of broiler chickens found a strong positive correlation between body core temperature and facial surface temperature, as recorded by infrared thermal imaging. The correlation was equally strong at all ages from 8 to 36 d during exposure to acute heat stress with or without proper ventilation and after acclimation to chronic heat exposure. A similar correlation was found by measurements in commercial flocks of broilers. Measurements of blood plasma concentrations of corticosterone, thyroid hormones, and arginine vasotocin confirmed that metabolic activity was low after acclimation to chronic exposure to heat, whereas ventilation was at least as efficient as acclimation in reducing thermal stress but did not impair metabolism. In light of these novel results, commercial benefits of infrared thermal imaging technology are suggested, especially in climate control for commercial poultry flocks. The application of this technique to other domestic animals should be investigated in future experiments.

Limb amputation is often an inevitable procedure in the advanced condition of various diseases and poses a dramatic impact on a patient's life. The aim of the present study is to analyze the impact of lower-limb amputations on aesthetic factors such as body image and self-esteem as well as quality of life (QoL). 298 patients (149 uni- or bilateral lower-limb amputees and 149 controls) were included in this cross-sectional study in three centers. Demographic data was collected and patients received a 118-item questionnaire including the Multidimensional Body-Self Relations Questionnaire (MBSRQ), the Rosenberg Self-esteem (RSE) scale and the SF-36 Health Survey (QoL). ANOVA and student's t-test were used for statistical analysis. Unilateral lower-limb amputees showed a significant lower MBSRQ score of 3.07±0.54 compared with 3.41±0.34 in controls (p<0.001) and a lower score in the RSE compared to controls (21.63±4.72 vs. 21.46±5.86). However, differences were not statistically significant (p = 0.36). Patients with phantom pain sensation had a significantly reduced RSE (p = 0.01). The SF-36 health survey was significantly lower in patients with lower-limb amputation compared to controls (42.17±14.47 vs. 64.05±12.39) (p<0.001). This study showed that lower-limb amputations significantly influence patients' body image and QoL. Self-esteem seems to be an independent aspect, which is not affected by lower-limb amputation. However, self-esteem is influenced significantly by phantom pain sensation.

BACKGROUND Acne vulgaris can severely affect social and psychological functioning. OBJECTIVE The aim of this study was to investigate the impact of acne vulgaris and its severity on Quality of Life of young adolescents in Greece. METHODS We conducted a questionnaire based survey among 1560 adolescent between the ages of 11 and 19 years old and 1531 of these were completed. Adolescents with acne filled all the questions including the Children Dermatology Life Quality Index. Adolescents without acne filled the questions about age, family history of acne, stress and smoking. Data were analyzed with Pearson Chi Square test. RESULTS Acne prevalence was 51.2% affecting both sexes equally. Self reported mild acne was present in 71.2% and moderate-severe acne in 28.8% of the study population. The mean age of the study population was 15.77y. The median score of Children Dermatology Life Quality Index was 4.02. The impact of acne on quality of life is associated with the severity of the acne (p<0.0001). Patients with moderate/severe acne experience greater psychosocial and emotional impairment (p<0.0001). Body image is modified proportionally to the severity of acne (p<0.0001). Symptoms and treatment of acne are factors that also influence their quality of life. Girls and boys are equally affected. Stress and heredity are correlated with acne and its severity (p<0.0001). We didn't find any correlation between smoking and acne. CONCLUSION Acne affects Quality of Life of young adolescents in Greece. The impact is proportional to the severity of acne. More severe acne is associated with greater effect on quality of life with implications for self esteem, body image and relationships with others. PMID:23197205

The relationship between body image, depression, food addiction and body mass index (BMI) and differences in these variables due to gender and field of education have not been studied extensively. This study was conducted on a total of 793 university students (20.19 ± 1.90 years). The Beck Depression Inventory, Yale Food Addiction, and Body Image Scale were used. It was determined that body image scores of females and individuals enrolled in health sciences programs were lower compared to those of males and those enrolled in the social sciences. There was a negative relationship between body image and depression and food addiction scores. There was a positive relationship between food addiction and depression scores, in addition to a positive relationship between food addiction and BMI.

This pilot study explored whether focusing on body functionality (i.e., everything the body can do) can protect women from potential harmful effects of exposure to thin-ideal images. Seventy women (Mage=20.61) completed an assignment wherein they either described the functionality of their body or the routes that they often travel (control). Afterward, participants were exposed to a series of thin-ideal images. Appearance and functionality satisfaction were measured before the assignment; appearance and functionality satisfaction, self-objectification, and body appreciation were measured after exposure. Results showed that participants who focused on body functionality experienced greater functionality satisfaction and body appreciation compared to control participants. Therefore, focusing on body functionality could be a beneficial individual-level technique that women can use to protect and promote a positive body image in the face of thin-ideal images. Research including a condition wherein participants are exposed to (product-only) control images is necessary to draw firmer conclusions. Copyright © 2016 Elsevier Ltd. All rights reserved.

Using modified constructivist grounded theory, the purpose of the present study was to explore positive body image experiences in people with spinal cord injury. Nine participants (five women, four men) varying in age (21-63 years), type of injury (C3-T7; complete and incomplete), and years post-injury (4-36 years) were recruited. The following main categories were found: body acceptance, body appreciation and gratitude, social support, functional gains, independence, media literacy, broadly conceptualizing beauty, inner positivity influencing outer demeanour, finding others who have a positive body image, unconditional acceptance from others, religion/spirituality, listening to and taking care of the body, managing secondary complications, minimizing pain, and respect. Interestingly, there was consistency in positive body image characteristics reported in this study with those found in previous research, demonstrating universality of positive body image. However, unique characteristics (e.g., resilience, functional gains, independence) were also reported demonstrating the importance of exploring positive body image in diverse groups.

A modified computational model of the human eye was used to obtain and compare different probability density functions, radial profiles of light pattern distributions, and images of the point spread function formed in the human retina under the presence of different kinds of particles inside crystalline lenses suffering from cataracts. Specifically, this work uses simple particles without shells and multilamellar bodies (MLBs) with shells. The emergence of such particles alters the formation of images on the retina. Moreover, the MLBs change over time, which affects properties such as the refractive index of their shell. Hence, this work not only simulates the presence of such particles but also evaluates the incidence of particle parameters such as particle diameter, particle thickness, and shell refractive index, which are set based on reported experimental values. In addition, two wavelengths (400 nm and 700 nm) are used for light passing through the different layers of the computational model. The effects of these parameters on light scattering are analyzed using the simulation results. Further, in these results, the effects of light scattering on image formation can be seen when single particles, early-stage MLBs, or mature MLBs are incorporated in the model. Finally, it is found that particle diameter has the greatest impact on image formation. PMID:28663924

Body surface area is important in determining the severity of psoriasis. However, objective, reliable, and practical method is still in need for this purpose. We performed a computer image analysis (CIA) of psoriatic area using the image J freeware to determine whether this method could be used for objective evaluation of psoriatic area. Fifteen psoriasis patients were randomized to be treated with adalimumab or placebo in a clinical trial. At each visit, the psoriasis area of each body site was estimated by two physicians (E-method), and standard photographs were taken. The psoriasis area in the pictures was assessed with CIA using semi-automatic threshold selection (T-method), or manual selection (M-method, gold standard). The results assessed by the three methods were analyzed with reliability and affecting factors evaluated. Both T- and E-method correlated strongly with M-method, and T-method had a slightly stronger correlation with M-method. Both T- and E-methods had a good consistency between the evaluators. All the three methods were able to detect the change in the psoriatic area after treatment, while the E-method tends to overestimate. The CIA with image J freeware is reliable and practicable in quantitatively assessing the lesional of psoriasis area. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Development of a semi-automated combined PET and CT lung lesion segmentation framework

Rossi, Farli; Mokri, Siti Salasiah; Rahni, Ashrani Aizzuddin Abd.

2017-03-01

Segmentation is one of the most important steps in automated medical diagnosis applications, which affects the accuracy of the overall system. In this paper, we propose a semi-automated segmentation method for extracting lung lesions from thoracic PET/CT images by combining low level processing and active contour techniques. The lesions are first segmented in PET images which are first converted to standardised uptake values (SUVs). The segmented PET images then serve as an initial contour for subsequent active contour segmentation of corresponding CT images. To evaluate its accuracy, the Jaccard Index (JI) was used as a measure of the accuracy of the segmented lesion compared to alternative segmentations from the QIN lung CT segmentation challenge, which is possible by registering the whole body PET/CT images to the corresponding thoracic CT images. The results show that our proposed technique has acceptable accuracy in lung lesion segmentation with JI values of around 0.8, especially when considering the variability of the alternative segmentations.

Bailey, K Alysse; Gammage, Kimberley L; van Ingen, Cathy; Ditor, David S

2017-09-01

This narrative explores the lived experience of a young woman, Rebecca, and her transitioned body image after sustaining and being treated for a spinal cord injury. Data were collected from a single semi-structured in-depth interview. Rebecca disclosed her transitioned body image experiences after sustaining a spinal cord injury and being treated by medical staff immediately following her injury. Before her injury, she described a holistic body experience and named this experience her "temple". During intensive care in the hospital, she explained her body was treated as an object. The disconnected treatment of her body led to a loss of the private self, as she described her sacred body being stripped away - her "temple" lost and in ruins. Body image may be an overlooked component of health following a spinal cord injury. This narrative emphasizes the importance of unveiling body image experiences after the treatment of a spinal cord injury to medical professionals. Lessons of the importance of considering the transitioned body experiences after a spinal cord injury may help prevent body-related depression and other subsequent health impacts.

Ultrasound provides a valuable tool for medical diagnosis offering real-time imaging with excellent spatial resolution and low cost. The advent of microbubble contrast agents has provided the additional ability to obtain essential quantitative information relating to tissue vascularity, tissue perfusion and even endothelial wall function. This technique has shown great promise for diagnosis and monitoring in a wide range of clinical conditions such as cardiovascular diseases and cancer, with considerable potential benefits in terms of patient care. A key challenge of this technique, however, is the existence of significant variations in the imaging results, and the lack of understanding regarding their origin. The aim of this paper is to review the potential sources of variability in the quantification of tissue perfusion based on microbubble contrast-enhanced ultrasound images. These are divided into the following three categories: (i) factors relating to the scanner setting, which include transmission power, transmission focal depth, dynamic range, signal gain and transmission frequency, (ii) factors relating to the patient, which include body physical differences, physiological interaction of body with bubbles, propagation and attenuation through tissue, and tissue motion, and (iii) factors relating to the microbubbles, which include the type of bubbles and their stability, preparation and injection and dosage. It has been shown that the factors in all the three categories can significantly affect the imaging results and contribute to the variations observed. How these factors influence quantitative imaging is explained and possible methods for reducing such variations are discussed. PMID:22866229

To implement and evaluate high spatial resolution three-dimensional MR contrast-enhanced angiography (3D-CEMRA) of the thighs using a blood pool contrast agent (BPCA) using the quadrature body coil only in patients with peripheral arterial occlusive disease (PAOD) in cases receiver coils cannot be used at 1.5 Tesla (T). Nineteen patients (mean age: 68.7 ± 11.2 years; range, 38-83 years) with known PAOD (Fontaine stages; III: 16, IV: 3) prospectively underwent 3D-CEMRA at 1.5T with a noninterpolated voxel size of 0.49 × 0.49 × 0.48 mm(3) . Digital subtraction angiography (DSA) was available for comparison in all patients. Two readers independently evaluated movement artifacts, overall image quality of 3D-CEMRA, and grade of stenosis as compared to DSA. SNR and CNR levels were quantified. The 3D-CEMRA was successfully completed in all patients. Patient movement artifacts that affected stenosis grading occurred in 3/38 thighs. Overall image quality was rated excellent in 15/38, good in 12/38, and diagnostic in 8/38 thighs. Stenosis grading matched with that in DSA in 35/38 thighs. High SNR and CNR were measured in all vessels. The 0.125 mm(3) spatial resolution 3D-CEMRA of the thighs with a BPCA is feasible using a quadrature body coil exclusively with excellent image quality despite long acquisition times. J. Magn. Reson.

Objective Numerous stand-alone interventions to improve body image have been developed. The present review used meta-analysis to estimate the effectiveness of such interventions, and to identify the specific change techniques that lead to improvement in body image. Methods The inclusion criteria were that (a) the intervention was stand-alone (i.e., solely focused on improving body image), (b) a control group was used, (c) participants were randomly assigned to conditions, and (d) at least one pretest and one posttest measure of body image was taken. Effect sizes were meta-analysed and moderator analyses were conducted. A taxonomy of 48 change techniques used in interventions targeted at body image was developed; all interventions were coded using this taxonomy. Results The literature search identified 62 tests of interventions (N = 3,846). Interventions produced a small-to-medium improvement in body image (d + = 0.38), a small-to-medium reduction in beauty ideal internalisation (d + = -0.37), and a large reduction in social comparison tendencies (d + = -0.72). However, the effect size for body image was inflated by bias both within and across studies, and was reliable but of small magnitude once corrections for bias were applied. Effect sizes for the other outcomes were no longer reliable once corrections for bias were applied. Several features of the sample, intervention, and methodology moderated intervention effects. Twelve change techniques were associated with improvements in body image, and three techniques were contra-indicated. Conclusions The findings show that interventions engender only small improvements in body image, and underline the need for large-scale, high-quality trials in this area. The review identifies effective techniques that could be deployed in future interventions. PMID:26418470

The objectives were to assess changes in sexual QOL and body image distress over time and to examine longitudinal associations between sexual QOL and body image variables with psychosocial outcomes in a sample of colorectal cancer patients. Participants (N = 141) completed a mail-based survey assessing sexual QOL [sexual distress (ISS), treatment impact on sexual function (SFQ), sexual function (FSFI; IIEF)], body image distress (BIS), and psychosocial outcomes [relationship quality (DAS-4), depressive symptoms (CESD-SF), and health-related QOL (HRQOL; FACT-C)]; 88 patients completed 6-month follow-up surveys (62%). Gender and cancer subgroups (male vs. female; rectal vs. colon cancer) were compared and longitudinal models examined associations between sexual QOL and body image variables with psychosocial outcomes over time and by subgroup. Impairments in sexual QOL and body image distress were common. Women and patients with rectal cancer reported worse body image distress compared to men (p = .005) and those with colon cancer (p = .03), respectively; compared to patients with colon cancer, those with rectal cancer reported worse treatment impact (p < .001) and marginally worse sexual function and HRQOL (p's = .05). At 6-month follow-up, body image distress decreased (p = .02), while sexual QOL was stable (e.g., 58% classified as dysfunctional at both time points, p = .13). For most sexual and body image predictors, worse impairment was associated with worse psychosocial outcomes over time. Several significant gender and cancer subgroup effects were found. Sexual QOL and body image are compromised after colorectal cancer and tend to remain impaired if unaddressed. Sexual concerns should be addressed early to limit broader-reaching psychosocial effects.

The increasing prevalence of obesity suggests a need to develop a convenient, reliable, and economical tool for assessment of this condition. Three-dimensional (3-D) body surface imaging has emerged as an exciting technology for the estimation of body composition. We present a new 3-D body imaging system, which is designed for enhanced portability, affordability, and functionality. In this system, stereo vision technology is used to satisfy the requirement for a simple hardware setup and fast image acquisition. The portability of the system is created via a two-stand configuration, and the accuracy of body volume measurements is improved by customizing stereo matching and surface reconstruction algorithms that target specific problems in 3-D body imaging. Body measurement functions dedicated to body composition assessment also are developed. The overall performance of the system is evaluated in human subjects by comparison to other conventional anthropometric methods, as well as air displacement plethysmography, for body fat assessment.

Gynecologic cancer is associated with long-term effects that can be both physical and emotional. We examined symptom prevalence and body image disturbance in patients with gynecologic cancer and their association with quality of life. Predictors of clinically-relevant body image disturbance were examined. A sample of patients in Singapore (n = 104) was assessed for symptom prevalence, quality of life, and body image dissatisfaction. Clinical factors were extracted from medical records. The most frequently reported symptoms were fatigue, abdominal bloatedness, weight gain, constipation, hot flashes, and pelvic pain. Approximately one quarter patients reported feeling less physically attractive and dissatisfied with their body. Ordinary least squares regression indicated that symptom prevalence alone predicted physical well-being, b = -1.09, P < .001, 95% CI, -1.45 to -0.73, and functional well-being, b = -0.88, P < .001, 95% CI, -1.32 to -0.45. Body image dissatisfaction alone significantly predicted emotional well-being, b = -0.21, P < .01, 95% CI, -0.35 to -0.06. Younger age was a significant risk factor for clinically-relevant score of body image distress, OR = 0.95 per year older, 95% CI, 0.92 to 0.99, P = .02. Symptom prevalence and body image dissatisfaction were associated with different domains of quality of life. Emotional well-being of patients was better explained by body image, rather than extent of symptoms experienced. Patients who are younger appear particularly susceptible to body image disturbance.

Obesity and weight gain after breast cancer treatment are common among survivors, yet the relationship between weight and body image has received little attention. The purpose of the current study was to examine the relationship between current body mass index, weight gain since diagnosis, and largest weight fluctuation in adulthood with six dimensions of body image among overweight/obese breast cancer survivors. The current study used data obtained from a weight control trial with 210 rural overweight/obese breast cancer survivors. Using data collected at baseline, multiple regression models were constructed to examine the relative association of the three weight variables with breast cancer-specific dimensions of body image while controlling for demographic characteristics and cancer treatment-related variables. Largest weight fluctuation in adulthood significantly predicted overall body image (p = 0.01) and was associated with the three socially oriented dimensions of body image: social activity restriction, embarrassment about appearance, and sexuality (all ps = 0.01). Weight gain since diagnosis approached statistical significance in predicting overall body image (p = 0.05) and was associated with embarrassment about appearance (p = 0.03). Current body mass index was not significantly associated with overall body image when controlling for the other weight variables (p = 0.07) and was negatively associated with social activity restriction (p = 0.01) and sexuality (p = 0.01). Obese breast cancer survivors with a history of a large weight fluctuation in adulthood may be prone to poorer breast cancer-specific body image several years after treatment.

Inflammatory bowel diseases (IBD) and their treatment are known to negatively impact on patients' body image, especially female patients. However, although there are broad evidences of body image impairment in female IBD patients, its negative impact on the quality of life (QoL) of non-operated women is not clearly and specifically studied. The aim of the current study was therefore to analyse, in a sample of non-operated female IBD patients, the factors that contribute to body image impairment and its impact on QoL. Ninety-six non-operated women (39.7 % with CD and 60.3 % with UC), aged between 18 and 40 years old, completed an online survey with validated self-report measures, which included the Body Image Scale and the WHO Brief Quality of Life Assessment Scale. Negative body image was correlated with lower psychological and physical QoL and increased corticosteroids use, associated medical complications, body mass index (BMI), and IBD symptomatology. Regression analyses revealed that BMI and IBD symptomatology significantly predicted body image impairment. Furthermore, results from path analyses indicated that BMI and IBD symptomatology's effect on psychological and physical QoL was mediated through the negative effects of body image impairment. This model explained 31 % of psychological QoL and 41 % of physical QoL. These findings suggest that non-operated female patients are subject to pervasive and harmful effects of body image impairment on psychological and physical functioning. Therefore, psychological interventions aiming to target body dissatisfaction should be implemented in the health care of IBD, independently of patients' operative status.

Cancer and its treatments have been shown to have a negative psychological effect on many cancer patients. One of these effects is often described as body image disturbance. Due to the limited number of studies in this area, this study was performed to assess body image in cancer patients and its association with clinical variables. This was a descriptive and correlational research that was designed in Sayyed-Al-Shohda Hospital affiliated to Isfahan University of Medical Sciences, Iran in 2013. Two hundred and ten adult patients who had been suffering from cancer were selected and completed the personal/demographic/illness questionnaire and the multi-dimensional body-self relations questionnaire that contained 64-items with appearance orientation, appearance evaluation, fitness evaluation, fitness orientation, health evaluation, health orientation, illness orientation, body areas satisfaction, self-classified weight and overweight preoccupation sub-scales. Data were analyzed by ANOVA and Pearson correlation with a significance level of P < 0.05. The mean (standard deviation (scores of body image in cancer patients was 184.40 (43.68) indicating that 58.3% of them had negative body image. In addition, most of patients had negative health evaluation (60.2%), negative appearance evaluation (63%), negative illness orientation (61%), and negative fitness orientation (56%). Furthermore, there were no significant correlations between type of cancer ( P = 0.5, f = 0.3), kind of treatment ( P = 0.8, f = 5.2) and duration of illness with body image ( P = 0.6, r = -0.2). In this study most of the cancer patients had body image disturbances. Also, body image in this group wasn't associated with the type of cancer, kind of treatment and duration of illness. Totally, these results underscore the importance of assessing and treating body image disturbance in cancer patients.

There is a lack of data on the association between body self-perception and eating patterns in Brazil. Thus, this study aimed to explore the relationship between body image dissatisfaction and eating patterns by the anthropometric status in adolescents. A cross-sectional study of 1496 adolescents was conducted. The participants completed the Body Shape Questionnaire. Demographic, anthropometric, and socioeconomic data were collected, as well as information regarding the pubertal development and dietary intake. Logistic regression was performed to evaluate the associations of interest. Body image dissatisfaction was identified in 19.5% of the adolescents. Three dietary patterns were identified: (1) the Western pattern was composed of sweets and sugars, soft drinks, typical dishes, pastries, fast food, beef, milk, and dairy products; (2) the Traditional pattern was composed of oils, chicken, fish, eggs, processed meat products, cereals (rice, cassava flour, pasta, etc.), baked beans, and bread; and (3) the Restrictive pattern was composed of granola, roots, vegetables, and fruit. Among overweight/obese adolescents, the data indicated a negative association of slight body image dissatisfaction (OR: 0.240 [0.100; 0.576]) and moderate body image dissatisfaction (OR: 0.235 [0.086; 0.645]) with the Western dietary pattern. Additionally, in this group, there was a positive association between high body image dissatisfaction and the Restrictive pattern (OR: 2.794 [1.178; 6.630]). Amongst overweight/obese adolescents, those with slight and moderate body image dissatisfaction were less likely to follow a Western-like dietary pattern when compared with those satisfied with their body image. Additionally, in this group, adolescents with high body image dissatisfaction was more likely to follow a restrictive pattern. Copyright © 2017 Sociedade Brasileira de Pediatria.

Research related to eating and body image disturbance in males has focused almost exclusively on Caucasian men. This preliminary study examined the prevalence of disturbed eating and body image symptomatology in a highly understudied and difficult to assess population-African-American men (n = 18) who have sex with men. Nineteen percent of the sample scored above clinical cut offs for possible eating disorders with 25% of the sample endorsing occasional or more frequent vomiting after meals. Use of appearance-changing supplements and substances were frequently reported. Although most body image measures were similar to norms, self-ideal discrepancy for muscularity was almost three times greater than male weightlifters. The implications of problematic body image and eating behaviors and the link between body image and high-risk sexual behaviors are discussed.

Cerebral palsy (CP) is the most common motor disorder of central origin in childhood and affects at least 2 children per 1000 live births every year. Neuroimaging techniques are needed to study neuroplastic rearrangements in the human brain in vivo as a result of CP. Unfortunately, accurate imaging from currently available techniques often requires the patients' complete body confinement, steadiness and minimal noise for a long period of time, which limits the success rate to less than 50% for normal children and worse for CP-affected ones. In this work we show that functional near infrared (fNIR) imaging is robust to motion artifacts and has excellent potential as a sensitive diagnostic tool for this motor disorder. We have analyzed data from pediatric normal and CP patients performing finger-tapping and handwaving motor cortex activation tasks. From these analyses we have identified both spatial and temporal metrics of NIR-based motor cortex activation patterns that can clearly distinguish between normal and CP patients. We also present data from additional patients where signal processing methods are applied to filter out concurrently recorded hemodynamic signals due to breathing and cardiac pulsation. It is shown that filtering can substantially improve the quality of activation data, thus enabling more accurate comparison of activation patterns between normal and CP-affected children.

An Examination of Participants Who Develop an Eating Disorder Despite Completing an Eating Disorder Prevention Program: Implications for Improving the Yield of Prevention Efforts

Numerous trials provide support for the Body Project, an eating disorder prevention program wherein young women with body image concerns critique the thin ideal. Despite medium to large effects, some participants subsequently develop an eating disorder, suggesting that intervention or recruitment procedures could be improved. This study investigated baseline and acute intervention predictors of DSM-5 eating disorder development during a 3-year follow-up among Body Project participants. Combined data from two trials compare participants who experienced eating disorder onset during follow-up (n=20) to those who did not (n=216). Participants who did versus did not develop an eating disorder started the intervention with higher eating disorder symptoms (η2=0.08), negative affect (η2=0.06), thin-ideal internalization (η2=0.02), and body dissatisfaction (η2=0.02); the same baseline predictors of eating disorder onset emerged in controls. Attenuated pre–post reductions in eating disorder symptoms (η2=0.01) predicted eating disorder onset but not after controlling for baseline levels. Given that Body Project and control participants who later developed an eating disorder started with initial elevations in risk factors and eating disorder symptoms, it might be useful to develop a more intensive variant of this program for those exhibiting greater risk at baseline and to deliver the prevention program earlier to prevent initial escalation of risk. The fact that nonresponders also showed greater negative affect and eating disorder symptoms suggests that it might be useful to add activities to improve affect and increase dissonance about disordered eating.

With the exclusion of studies in individuals with eating disorders, few investigators have examined body image issues in patients with borderline personality disorder (BPD). In this study, we examined among psychiatric inpatients relationships between body image and BPD. In a cross-sectional sample of convenience, we surveyed 126 women in an inpatient psychiatric unit using 5 measures for body image and 2 measures for BPD. Using standardized cutoffs for BPD diagnosis, participants with BPD demonstrated a number of differentiating features with regard to body image issues. Explicitly, BPD did not seem to be related to being self-conscious about one's appearance, although BPD was related to being more self-conscious, in general. Individuals with BPD were not more invested in their appearance as a source of self-definition but evaluated their own appearance more negatively and were more likely to believe that attractiveness is an important factor for happiness and acceptance. Although BPD was not related to perceptions about the strength and competence of one's own body, those with BPD indicated less comfort and trust in their own bodies. In general, it appeared that body image measures that were more perceptually grounded were more likely to be similar to non-BPD participants, whereas body image measures that were more cognitively grounded were more likely to be statistically significantly different in comparison with non-BPD participants. Psychiatric inpatients with BPD demonstrate a number of disturbances in body image. Copyright © 2010 Elsevier Inc. All rights reserved.

Knowledge of heat transfer in biological bodies has many diagnostic and therapeutic applications involving either raising or lowering of temperature, and often requires precise monitoring of the spatial distribution of thermal histories that are produced during a treatment protocol. The present paper therefore aims to design and implementation of laser therapeutic and imaging system used for carious tracking and drilling by develop a mathematical algorithm using Hilbert transform for edge detection of photo-thermal imaging. photothermal imaging has the ability to penetrate and yield information about an opaque medium well beyond the range of conventional optical imaging. Owing to this ability, Q- switching Nd:YAG laser at wavelength 1064 nm has been extensively used in human teeth to study the sub-surface deposition of laser radiation. The high absorption coefficient of the carious rather than normal region rise its temperature generating IR thermal radiation captured by high resolution thermal camera. Changing the pulse repetition frequency of the laser pulses affects the penetration depth of the laser, which can provide three-dimensional (3D) images in arbitrary planes and allow imaging deep within a solid tissue.

The research on binge eating has overwhelmingly focused on Whites. We aimed to study gender and ethnic differences in the association between body image dissatisfaction and binge eating in a nationally representative sample of Black adults in the USA. This cross-sectional study used data from the National Survey of American Life (NSAL), 2003-2004. Self-identified Caribbean Black (n = 1621) and African American (3570) adults aged 18 and older were enrolled. The independent variable was body dissatisfaction measured with two items. Using the World Health Organization Composite International Diagnostic Interview (WHO-CIDI), outcome was lifetime binge eating without hierarchy according to the DSM-IV criteria. Covariates included age, socioeconomic factors (i.e., education and marital status), and body mass index. Ethnicity and gender were focal moderators. Logistic regressions were used for data analysis. Despite comparable prevalence of lifetime binge eating (5 vs 4 %, p > 0.05), African Americans reported higher body image dissatisfaction than Caribbean Blacks (36 vs 29 %, p > 0.05). In the pooled sample, body dissatisfaction was a strong predictor of lifetime binge eating disorders. There was a significant interaction (p = 0.039) between ethnicity and body image dissatisfaction on binge eating, suggesting a stronger association between body image dissatisfaction and lifetime binge eating for Caribbean Blacks (OR = 11.65, 95 % 6.89-19.72) than African Americans (OR = 6.72, 95 % CI 3.97-11.37). Gender did not interact with body image dissatisfaction on binge eating. Ethnic variation in the link between body image dissatisfaction and binge eating may be due to within-race cultural differences in body image between African Americans and Caribbean Blacks. This may include different definitions, norms, and expectations regarding the body size. Findings suggest that ethnicity may bias relevance of body image dissatisfaction as a diagnostic criterion for binge eating disorders among diverse populations of Blacks.

Previous studies found important associations between body image, sexual satisfaction, and perceived romantic relationship quality, but mainly focused on one individual's perceptions rather than both partners. To take the interdependency of romantic partners into account, the present study examined these associations in romantic couples with a dyadic approach. In a cross-sectional design, 151 Dutch heterosexual couples completed an online survey measuring body image, sexual satisfaction, and perceived relationship quality. Hypotheses were tested using the actor-partner interdependence model (APIM) and an APIM extended with a mediator (APIMeM), with couple members' body image as predictors, couple members' sexual satisfaction as mediators, and couple members' relationship quality as outcomes. Results indicated that within individuals, a more positive body image was linked to higher perceived romantic relationship quality through greater sexual satisfaction. No gender differences were found, implying that body image and sexual satisfaction are equally strongly associated with perceived relationship quality in women and men. Results revealed no associations of an individual's body image and sexual satisfaction with the partner's perceived relationship quality. These findings implicate that interventions focusing on developing and maintaining a positive body image may be helpful in building on a more satisfying sex life and higher perceived relationship quality.

The purpose of this study was to determine factors associated with self-perceived body image in female patients with head and neck cancer (HNC), and factors associated with healthcare professional's rating of disfigurement, as well as the correlation between patient and observer ratings. This cross-sectional study recruited 105 women with HNC at a large medical centre. Measures of facial disfigurement and body image, as well as demographic and clinical characteristics, were collected. Multivariate multiple linear regression modelling was used to identify factors associated with healthcare professional's rating of disfigurement and patient self-perceived body image. Disfigurement ratings by healthcare professionals were positively associated with patient self-perceived body image. Medical treatment, cancer stage, radiation dose and cancer site were significantly associated with disfigurement. Medical treatment was an important predictor of perceived body image. These findings indicate a moderate prevalence of disfigurement among women with HNCs. Patients with more disfigurement were more likely to have dissatisfaction with their body image. Nursing professionals need to carefully assess the appearance of women with HNC. Camouflage interventions can be used to help appropriately cope with the disfigurement, and to achieve improved satisfaction with their body image. © 2017 John Wiley & Sons Ltd.

Assessing the body image: relevance, application and instruments for oncological settings.

2012-05-01

Body image is the sum of physical, cognitive, emotional, and relational elements that, when integrated, allow the development of a whole, healthy self-identity. Even though body image is normally studied in relation to eating disorders, it can also be influenced by other pathologies, including cancer. In oncology, an effective body image assessment is fundamental. The physical effects of cancer and cancer treatments are important and frequently irreversible also on a functional and emotional level; however, only few surveys have investigated body image in this peculiar context. An extensive literature review was carried out in PubMed and PsycINFO. We considered articles published from 1990 to 2010. Two hundred sixty-three papers matched the search criteria. Assessment methodologies included clinical interviews, self-report measures, questionnaires, symptom check lists, and graphic tests and projective techniques. After excluding the instruments that referred to eating disorders, validated only for adolescents, and/or projective and graphic tests, we found 81 articles with six questionnaires specifically dedicated to body image assessment in oncology. From our systematic review, we could identify six instruments specifically designed for assessing body image in the oncological area. In this paper, we discuss their general characteristics, psychometrics properties and the clinical implications, and body image relevance on the quality of life in cancer patients.

Human and animal sounds influence recognition of body language.

Van den Stock, Jan; Grèzes, Julie; de Gelder, Beatrice

2008-11-25

In naturalistic settings emotional events have multiple correlates and are simultaneously perceived by several sensory systems. Recent studies have shown that recognition of facial expressions is biased towards the emotion expressed by a simultaneously presented emotional expression in the voice even if attention is directed to the face only. So far, no study examined whether this phenomenon also applies to whole body expressions, although there is no obvious reason why this crossmodal influence would be specific for faces. Here we investigated whether perception of emotions expressed in whole body movements is influenced by affective information provided by human and by animal vocalizations. Participants were instructed to attend to the action displayed by the body and to categorize the expressed emotion. The results indicate that recognition of body language is biased towards the emotion expressed by the simultaneously presented auditory information, whether it consist of human or of animal sounds. Our results show that a crossmodal influence from auditory to visual emotional information obtains for whole body video images with the facial expression blanked and includes human as well as animal sounds.

Many young adolescents are dissatisfied with their body due to a discrepancy between their ideal and actual body size, which can lead to weight cycling, eating disorders, depression, and obesity. The current study examined the associations of parental and peer factors with fifth-graders’ body image discrepancy, physical self-worth as a mediator between parental and peer factors and body image discrepancy, and how these associations vary by child’s sex. Body image discrepancy was defined as the difference between young adolescents’ self-perceived body size and the size they believe a person their age should be. Data for this study came from Healthy Passages, which surveyed 5,147 fifth graders (51 % females; 34 % African American, 35 % Latino, 24 % White, and 6 % other) and their primary caregivers from the United States. Path analyses were conducted separately for boys and girls. The findings for boys suggest father nurturance and getting along with peers are related negatively to body image discrepancy; however, for girls, fear of negative evaluation by peers is related positively to body image discrepancy. For both boys and girls, getting along with peers and fear of negative evaluation by peers are related directly to physical self-worth. In addition, mother nurturance is related positively to physical self-worth for girls, and father nurturance is related positively to physical self-worth for boys. In turn, physical self-worth, for both boys and girls, is related negatively to body image discrepancy. The findings highlight the potential of parental and peer factors to reduce fifth graders’ body image discrepancy. PMID:23334988

The number of people being affected by Diabetes mellitus worldwide is increasing at an alarming rate. Monitoring of the diabetic condition and its effects on the human body are therefore of great importance. Of particular interest is diabetic retinopathy (DR) which is a result of prolonged, unchecked diabetes and affects the visual system. DR is a leading cause of blindness throughout the world. At any point of time 25 - 44% of people with diabetes are afflicted by DR. Automation of the screening and monitoring process for DR is therefore essential for efficient utilization of healthcare resources and optimizing treatment of the affected individuals. Such automation would use retinal images and detect the presence of specific artifacts such as hard exudates, hemorrhages and soft exudates (that may appear in the image) to gauge the severity of DR. In this paper, we focus on the detection of hard exudates. We propose a two step system that consists of a screening step that classifies retinal images as normal or abnormal based on the presence of hard exudates and a detection stage that localizes these artifacts in an abnormal retinal image. The proposed screening step automatically detects the presence of hard exudates with a high sensitivity and positive predictive value (PPV ). The detection/localization step uses a k-means based clustering approach to localize hard exudates in the retinal image. Suitable feature vectors are chosen based on their ability to isolate hard exudates while minimizing false detections. The algorithm was tested on a benchmark dataset (DIARETDB1) and was seen to provide a superior performance compared to existing methods. The two-step process described in this paper can be embedded in a tele-ophthalmology system to aid with speedy detection and diagnosis of the severity of DR.

Body image and disordered eating research has focused mostly on the female experience. The present study examined gender differences in the relationship between personality, disordered eating, and body image dissatisfaction. Participants were 238 female and 85 male undergraduates ( M age  = 20.52 years, SD  = 4.22) at a Canadian university. Materials included a battery of self-report questionnaires pertaining to personality, body image, and disordered eating. As expected, females reported more body dissatisfaction and disordered eating than males. Personality factors were found to be significantly related to the experience of body dissatisfaction in both genders. Further, several personality traits significantly contributed to the prediction of male (high Neuroticism, low Conscientiousness) and female (high Neuroticism) body dissatisfaction beyond the influence of body mass index (BMI). Interestingly, and contrary to findings with female participants, personality traits were not significantly related to disordered eating scores in men. Among women, disordered eating scores were significantly predicted by high Neuroticism and Extraversion, and low Conscientiousness. Although the relationship between disordered eating, body image dissatisfaction, and personality is well-documented in females, this relation may differ for males. The focus on male body image has been increasing in Western society; exploring how males view their bodies may be beneficial to researchers and clinicians alike.

This research examined the effects of appearance-based comparisons to muscular and slender idealized male bodies and the contribution of internalization and social comparison to change in body dissatisfaction. Participants were 111 male undergraduates who completed measures of body dissatisfaction, internalization, and social comparison and viewed images of either muscular or slender men in advertisements or product-only advertisements. Results indicated that exposure to both muscular and slender images was associated with an increase in body dissatisfaction, with no significant differences in the change in body dissatisfaction between the two image conditions. Internalization and trait social comparison were each associated with an increase in body dissatisfaction; however, upward social comparison was only a significant predictor of a change in body dissatisfaction for the males who viewed muscular images. These results highlight the impact of slender models on young men's body dissatisfaction and support the examination of media literacy interventions with this population.

The impact of thin idealized media images on body satisfaction: does body appreciation protect women from negative effects?

This article examines whether positive body image can protect women from negative media exposure effects. University women (N=112) were randomly allocated to view advertisements featuring ultra-thin models or control images. Women who reported high levels of body appreciation did not report negative media exposure effects. Furthermore, the protective role of body appreciation was also evident among women known to be vulnerable to media exposure. Women high on thin-ideal internalization and low on body appreciation reported appearance-discrepancies that were more salient and larger when they viewed models compared to the control group. However, women high on thin-ideal internalization and also high on body appreciation rated appearance-discrepancies as less important and no difference in size than the control group. The results support the notion that positive body image protects women from negative environmental appearance messages and suggests that promoting positive body image may be an effective intervention strategy.

To examine whether body image mediates the association between overweight/obesity and chronic disease-related health practices (CDRHP), including lack of physical activity (PA), infrequent breakfast consumption (IBC), screen-based media use (SBM), and smoking. The 2006 Health Behaviors in School-Age Children survey was administered to a nationally representative sample of US students (n = 8,028) in grades 6-10 (mean age = 14.3 years). Outcome variables included self-reported measures of PA, SBM, IBC, and smoking. Body image was assessed with 5 items from the Body Investment Scale (α = 0.87) asking for agreement/disagreement with statements about one's body. Stratifying on gender, an initial regression model estimated the association between overweight/obesity and CDRHP. Mediation models that included body image were then compared to the initial model to determine the role of body image in the relationship between overweight/obesity and CDRHP. Among boys, body image mediated the relationships of overweight/obesity with SBM, and of obesity with IBC. Among girls, it mediated the relationships of obesity with PA, IBC, and smoking, and of overweight with SBM. As the prevalence of overweight/obesity among adolescent boys and girls remains high, efforts to improve their body image could result in less frequent engagement in CDRHP. © 2013 S.

Fabry disease is an X-linked disorder of glycosphingolipid metabolism, in which a partial or total deficiency of [alpha]-galactosidase A, a lysosomal enzyme, results in the progressive accumulation of neutral glycosphingolipids (globotriaosylceramide and digalactosylceramide) in most fluids and tissues of the body. Few information is available about the composition and distribution in tissues of the accumulated glycosphingolipids species. Mass spectrometry imaging is an innovative technique, which can provide pieces of information about the distribution of numerous biological compounds, such as lipids, directly on the tissue sections. MALDI-TOF and cluster-TOF-SIMS imaging approaches were used to study the localization of lipids (cholesterol, cholesterol sulfate, vitamin E, glycosphingolipids ...) on skin and kidney sections of patients affected by the Fabry disease. Numerous information on pathophysiology were enlightened by both techniques.
