    Bosson, Jennifer K.; Pinel, Elizabeth C.; Thompson, J. Kevin

    2008-01-01

    We propose that women regularly anticipate and receive messages from others that trivialize the severity of their body image concerns. Moreover, we suggest that these minimizing messages can heighten women's negative affective reactions to body image threats, particularly if they internalize them. Two studies provided support for these ideas. In…

    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.

    Research has shown that non-clinical women, particularly those with high body concern, engage in frequent body checking behaviors. The purpose of this study was to use ecological momentary assessment (EMA) to examine the frequency and correlates of body checking behavior, including its association with body image dissatisfaction and negative affect, in non-clinical women with high body concern. Undergraduate female participants with high body concern (n=22) were assessed five times per day for five days via text messages sent to their smart phones. During each assessment, participants reported the number of times they engaged in eight different body checking behaviors and their current level of negative affect and body dissatisfaction. After aggregation, a total of 3064 body checking behaviors were reported by the sample during the five-day period. All participants reported engaging in body checking at least once per day, with a mean of 27.85 checking behaviors per day. Hierarchical Linear Modeling revealed that body checking significantly predicted both body dissatisfaction and negative affect. These results provide preliminary support for the cognitive behavioral theory of eating disorders, suggesting that as women engage in more frequent body checking behaviors, they also experience higher levels of body dissatisfaction and negative affect.

    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.

  5. Considering an affect regulation framework for examining the association between body dissatisfaction and positive body image in Black older adolescent females: does body mass index matter?

    The present study provided an initial evaluation of an affect regulation model describing the association between body dissatisfaction and two contemporary measures of positive body image among 247 Black college-bound older adolescent females. We further tested whether possessing a higher body mass index (BMI) would strengthen these associations. Self-reported height and weight were used to calculate BMI. Respondents also completed a culturally-sensitive figure rating scale along with assessments of body appreciation and body image flexibility. Results indicated a robust positive association between the two measures of positive body image; BMI was the strongest predictor of both body appreciation and body image flexibility with body size discrepancy (current minus ideal) contributing incremental variance to both models tested. Implications for improving our understanding of the association between positive and negative body image and bolstering positive body image to promote health-protective behaviors among Black young women at this developmental juncture are discussed.

    2014-01-01

    Previous descriptive, correlational, and quasi-experimental research has established that weight concerns and negative body image are associated with tobacco smoking, cessation, and relapse among young women. A recent experimental study found that activation of negative body image cognitions produced urges to smoke (Lopez, Drobes, Thompson, & Brandon, 2008). The current study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N = 133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and post-manipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation, and that this effect occurs, at least in part, via increases in negative affect. Theoretical and applied implications are discussed. PMID:19586144

    Magnetic Resonance Imaging (MRI) and Computer-aided Tomography (CT) images are often complementary. In most cases, MRI is good for viewing soft tissue but not bone, while CT images are good for bone but not always good for soft tissue discrimination. Physicians and engineers in the Department of Radiology at the University of Michigan Hospitals are developing a technique for combining the best features of MRI and CT scans to increase the accuracy of discriminating one type of body tissue from another. One of their research tools is a computer program called HICAP. The program can be used to distinguish between healthy and diseased tissue in body images.

    The high-tech art of digital signal processing (DSP) was pioneered at NASA's Jet Propulsion Laboratory (JPL) in the mid-1960s for use in the Apollo Lunar Landing Program. Designed to computer enhance pictures of the Moon, this technology became the basis for the Landsat Earth resources satellites and subsequently has been incorporated into a broad range of Earthbound medical and diagnostic tools. DSP is employed in advanced body imaging techniques including Computer-Aided Tomography, also known as CT and CATScan, and Magnetic Resonance Imaging (MRI). CT images are collected by irradiating a thin slice of the body with a fan-shaped x-ray beam from a number of directions around the body's perimeter. A tomographic (slice-like) picture is reconstructed from these multiple views by a computer. MRI employs a magnetic field and radio waves, rather than x-rays, to create images.

    Body image (BI) can be described as the assessment of both positive and negative emotion for one's own body parts and their characteristics by himself or herself. Current research has concentrated mostly on the status of negative BI as a risk factor for mental health problems rather than as a public health problem, thereby little is known about the effects of BI on quality of life. Thus, the purpose of this study was to assess the BI and Quality of Life (QoL) of individuals and to investigate the relationship between the two. Individuals over 15 living in Isparta city center constitute the universe of this cross-sectional analytical study, carried out in 2014. The BI of individuals was measured by the Body Image Scale and The QoL of individuals was measured using the World Health Organization (WHO) Quality of Life Scale Short Form. The mean age of the participants was 31.9 ± 13.0 and 56.0% were female, 36.8% were married and 81.7% had education above high school. 25.7% had at least one chronic disease and 17.7% received medication regularly. Having good-very good health perception, having higher income than expenses, making regular exercises were predictors in enhancing the quality of life in certain aspects, however having a good body image came out as a predictor enhancing the quality of life in all sub-domains. BI was found closely related with QoL in all sub-domains. Our findings suggest that greater attention should be to be given to BI as a strong predictor of QoL. PMID:27649389

    Most people would like to change something about their bodies and the way that they look, but for some it becomes an obsession. A healthy skin plays an important role in a person's physical and mental wellbeing, whereas a disfiguring appearance is associated with body image concerns. Skin diseases such as acne, psoriasis and vitiligo produce cosmetic disfigurement and patients suffering these and other visible skin conditions have an increased risk of depression, anxiety, feelings of stigmatization and self-harm ideation. Body image affects our emotions, thoughts, and behaviours in everyday life, but, above all, it influences our relationships. Furthermore, it has the potential to influence our quality of life. Promotion of positive body image is highly recommended, as it is important in improving people's quality of life, physical health, and health-related behaviors. Dermatologists have a key role in identifying body image concerns and offering patients possible treatment options. PMID:27283435

    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.

    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.

    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.

    Body image inflexibility, the unwillingness to experience negative appearance-related thoughts and emotions, is associated with negative body image and eating disorder symptoms. The present study investigated whether body image inflexibility mediated the relationship between body image evaluation and maladaptive body image coping strategies (appearance-fixing and experiential avoidance) in a college and community sample comprising 156 females aged 18-51 years (M=22.76, SD=6.96). Controlling for recruitment source (college vs. community), body image inflexibility fully mediated the relationship between body image evaluation and maladaptive body image coping strategies. Results indicated that an unwillingness to experience negative appearance-related thoughts and emotions is likely responsible for negative body image evaluation's relationship to appearance-fixing behaviours and experiential avoidance. Findings support extant evidence that interventions that explicitly target body image inflexibility, such as Acceptance and Commitment Therapy, may have utility in treating body dissatisfaction in nonclinical populations.

    "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.

    This study examined the feasibility of performing radiographic studies on patients wearing standard-issue body armor. The Kevlar helmet, fragmentation vest, demining suit sleeve, and armor plate were studied with plain film and computed tomography in a simulated casualty situation. We found that the military helmet contains metal screws and metal clips in the headband, but diagnostic computed tomographic images can be obtained. Kevlar, the principal component of soft armor, has favorable photon attenuation characteristics. Plate armor of composite material also did not limit radiographic studies. Therefore, when medically advantageous, patients can be examined radiographically while wearing standard military body armor. Civilian emergency rooms should be aware of these observations because law enforcement officers wear similar protective armor. PMID:11977874

    We examined whether implicit measures of actual and ideal body image can be used to predict body dissatisfaction in young female adults. Participants completed two Implicit Relational Assessment Procedures (IRAPs) to examine their implicit beliefs concerning actual (e.g., I am thin) and desired ideal body image (e.g., I want to be thin). Body dissatisfaction was examined via self-report questionnaires and rating scales. As expected, differences in body dissatisfaction exerted a differential influence on the two IRAP scores. Specifically, the implicit belief that one is thin was lower in participants who exhibited a high degree of body dissatisfaction than in participants who exhibited a low degree of body dissatisfaction. In contrast, the implicit desire to be thin (i.e., thin ideal body image) was stronger in participants who exhibited a high level of body dissatisfaction than in participants who were less dissatisfied with their body. Adding further weight to the idea that both IRAP measures captured different underlying constructs, we also observed that they correlated differently with body mass index, explicit body dissatisfaction, and explicit measures of actual and ideal body image. More generally, these findings underscore the advantage of using implicit measures that incorporate relational information relative to implicit measures that allow for an assessment of associative relations only.

    Previous research has revealed affect-congruity effects for the recognition of affects from faces. Little is known about the impact of affect on the perception of body language. The aim of the present study was to investigate the relationship of implicit (versus explicit) affectivity with the recognition of briefly presented affective body expressions. Implicit affectivity, which can be measured using indirect assessment methods, has been found to be more predictive of spontaneous physiological reactions than explicit (self-reported) affect. Thirty-four healthy women had to label the expression of body postures (angry, fearful, happy, or neutral) presented for 66 ms and masked by a neutral body posture in a forced-choice format while undergoing functional magnetic resonance imaging (fMRI). Participants' implicit affectivity was assessed using the Implicit Positive and Negative Affect Test. Measures of explicit state and trait affectivity were also administered. Analysis of the fMRI data was focused on a subcortical network involved in the rapid perception of affective body expressions. Only implicit negative affect (but not explicit affect) was correlated with correct labeling performance for angry body posture. As expected, implicit negative affect was positively associated with activation of the subcortical network in response to fearful and angry expression (compared to neutral expression). Responses of the caudate nucleus to affective body expression were especially associated with its recognition. It appears that processes of rapid recognition of affects from body postures could be facilitated by an individual's implicit negative affect. PMID:26032148

    Body image is an important concept that has a significant effect on a person's self-esteem and self-confidence. Appreciating how the older body is perceived by a woman is an important first step to understanding how nurses might support patient dignity. This article reviews the latest literature on ageing and body image and suggests practical dialogues that nurses and patients can share.

  12. Perceptual adaptation affects attractiveness of female bodies.

    Winkler, Christopher; Rhodes, Gillian

    2005-05-01

    We investigated whether short durations (5 minutes) of exposure to distorted bodies can change subsequent perceptions of attractiveness and normality. Participants rated 110 female bodies, varying in width, on either their attractiveness or normality before and after exposure to either extremely narrow (-50% of original width in Experiments 1 and 2) or extremely wide bodies (+50% of original width in Experiment 1, and +70% of original width in Experiment 2). In both experiments, the most attractive and most normal looking bodies became significantly and substantially narrower after exposure to narrow bodies. The most normal looking body changed significantly after exposure to wide bodies, but the most attractive body did not. These results show that perceptions of body attractiveness can be influenced by experience, but that there is an asymmetry between the effects of exposure to narrow and wide bodies. We consider a possible mechanism for this unexpected asymmetry, as well as possible implications for the effects of media exposure on body-image. The most attractive body shape was consistently narrower than the most normal looking body shape. Substantial changes in what looked normal were accompanied by congruent changes in what looked attractive, suggesting that a normal or average body shape may function as a reference point against which body attractiveness is judged.

    This study investigated the association between body image and body-image self-consciousness on sexual satisfaction, accounting for relationships between body fat and body image, and between sexual functioning and sexual satisfaction, while controlling for relationship satisfaction. Participants were 143, 18-25 year-old Caucasian men and women in heterosexual monogamous relationships, recruited from the University of Guelph and surrounding community in Ontario, Canada. Various domains of body image, body-image self-consciousness, sexual satisfaction and functioning, and relationship satisfaction data were collected by questionnaires. Body fat was measured using dual energy X-ray absorptiometry. Among men, body image was positively associated with sexual satisfaction, after controlling for relationship satisfaction. Men with greater body fat were more likely to have poorer behavioral and affective body image. Only body image specific to the sexual encounter influenced sexual functioning. Among women, no domain of body image was associated with sexual satisfaction, after controlling for relationship satisfaction. Women with greater body fat were more likely to have poorer affective and sexual-encounter-specific body image. As percent total fat increased, sexual functioning decreased. Our results suggest a complex pattern of relationships exists among body image and body composition constructs and sexual and relationship variable; and that these relationships are not the same for men and women.

  14. [Obesity: stigmatization, discrimination, body image].

    PubMed

    Kinzl, Johann F

    2016-03-01

    Obesity is a heterogeneous condition with multifactorial genesis (genetic predisposition, life-style, psychosocial situation), but there is a relatively homogeneous negative stereotype of obese individuals, because overweight and obesity are seen as self-inflicted disorders caused by physical inactivity and disorderd eating behavior. Obese individuals are confronted with far-reaching stigmatization and discrimination. Typical stereotypes are laziness, unattractiveness, work refusal. This negative image by the environment contributes to negative self-awareness and self-stigmatization, accompanied by a poor self-esteem and feelings of poor self-control and reduced self-efficacy, resulting in poor constructive coping strategies for overweight reduction. In addition, a disturbed body image combined with deep dissatisfaction with their own body is often found in many obese individuals. There is not always a close connection between body weight and body dissatisfaction. Young women and individuals with a binge eating disorder often show an increased body dissatisfaction as well.

    Studies have shown that dispositional mindfulness, a construct characterized by awareness and attention to present moment experiences, is associated with body image constructs in women. However, little is known about the relationship between dispositional mindfulness and body image among men. Therefore, this study examined the unique associations between dispositional mindfulness and three body image variables in men: overall appearance evaluation, satisfaction with distinct body areas, and drive for muscularity. Undergraduate men (N=296) completed the Multidimensional Body Self-Relations Questionnaire-Appearance Scales, the Drive for Muscularity Scale, the Mindful Attention Awareness Scale, and the Positive and Negative Affect Schedule. A series of hierarchical regression analyses revealed that mindfulness was uniquely associated with all three body image variables after accounting for body mass index and negative affect. Results are discussed with regard to the potential role of dispositional mindfulness in body dissatisfaction among men.

    Drug smuggling by intra-abdominal concealment, so called "body packing," has recently increased, even in Japan. Because of fatal drug intoxication and other adverse side effects, it is important to make a radiological diagnosis of body packers as soon as possible. A retrospective analysis of the images of plain abdominal radiography, computed tomography (CT) and ultrasound (US) was performed in twenty-three body packers to evaluate the imaging characteristics of three drugs (cannabis, cocaine and heroin). Cannabis (16 patients) and cocaine (5 patients) packages were demonstrated as well-demarcated rectangular-shaped high-density shadows surrounded by gas halo ("double condom sign") in abdominal plain radiographs and CT. Heroin packages (2 patients) were demonstrated as obscure shadows and were difficult to identify on plain radiographs, because they resembled stool masses. US was performed in one cannabis patient because of the refusal of radiological examination, and packages were demonstrated as round echogenic structures with dorsal echo extinctions. In conclusion, abdominal plain radiography, CT and US represent valuable diagnostic modalities in the assessment of body packers.

    2015-01-01

    Research on stereotypes demonstrates how existing prejudice affects the way we process outgroups. Recent studies have considered whether it is possible to change our implicit social bias by experimentally changing the relationship between the self and outgroups. In a number of experimental studies, participants have been exposed to bodily illusions that induced ownership over a body different to their own with respect to gender, age, or race. Ownership of an outgroup body has been found to be associated with a significant reduction in implicit biases against that outgroup. We propose that these changes occur via a process of self association that first takes place in the physical, bodily domain as an increase in perceived physical similarity between self and outgroup member. This self association then extends to the conceptual domain, leading to a generalization of positive self-like associations to the outgroup. PMID:25524273

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.

    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. PMID:26347007

    Two online surveys examined the significance of the visual analogues, or 'avatars', men (total N=266) create and use online. Two-dimensional (adiposity×muscle) somatomorphic matrices revealed that avatars are generally thinner than their creator's actual body and similar to their ideal, but more muscular than either their actual or ideal. Men's ratings of the importance of their avatar's appearance correlated with their actual weight and muscle concerns, and disparity between their avatar and actual body dimensions predicted their offline context body change concerns additional to that accounted for by disparity between their ideal and actual bodies. Together with the observation that men also reported higher self-esteem, less social interaction anxiety and less social phobia while online (which correlated with the time they spent online), these results suggest that the physical dimensions of avatars used in social interactions online may serve a compensatory function.

    This article reviews the literature on body image and media use among adolescents. We begin by defining body image and how it is constructed, especially among young people. We then offer information on when one's body image perception is askew with one's perception of personal ideal, which can result in disordered eating, including obesity, anorexia, and bulimia. Next, we describe the research literature on media use and its relationship to adolescents' body image perceptions and discuss content analyses and correlational, experimental, and qualitative studies. Lastly, we recommend, beyond conducting further and improved research studies, interventions and policies that may have an impact on body image and media use.

    In 2 studies, the authors evaluated the role of parents, peers, and the media in body image and body-change strategies among adolescent boys and girls. The respondents for Study 1 (423 boys and 377 girls) completed the Body Image and Body Change Inventory (L. A. Ricciardelli & M. P. McCabe, 2002) and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire (M. P. McCabe & L. A. Ricciardelli, 2001b). Body mass index and age were also included in the analyses. Regression analyses demonstrated that sociocultural influences and feedback from the participant's best male friend were important predictors for all body-change strategies among boys. For girls, sociocultural influences and feedback from the participant's best female friend and mother were important predictors for body-change strategies. The most consistent predictor of weight loss, weight gain, and strategies to increase muscles was body-image importance. In Study 2, the authors examined the influence of the same sociocultural variables, as well as negative affect and puberty on body image and body-change strategies among a second group of 199 boys and 267 girls. The results demonstrated that a broad range of sociocultural influences predicted body-change strategies for boys and girls, with negative affect also having a unique influence for boys but not for girls. Puberty played a minor role, once other sociocultural variables were entered into the regression equation. The implications of these findings are discussed.

    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

This exploratory study aimed to characterize body image perceptions among youth living with HIV. Adolescents (n = 143; age range 16-24 years; 69 % male) completed an Audio Computer Assisted Self-Interview Questionnaire that assessed body image, psychosocial, medical and sociodemographic information. Medical history and physical functioning information were abstracted from medical records. Results showed normative global body image on the Multidimensional Body Self-Relations Questionnaire-Appearance Scales. Some subscale elevations were observed; including decreased interest in self-care and appearance, as well as concerns with individual body areas. Overall, youth reported preference for own body shape on the Figure Rating Scale; however, 41 % of youth classified as "overweight" per CDC body mass index reported contentment with current body size. Further, 47 % of youth classified as "normal" weight desired to have larger body size. Youth identified as men who have sex with men most often reported desiring larger body size. Implications for clinical care are discussed. PMID:26721247

    2013-10-01

    Distortions of body image have often been investigated in clinical disorders. Much of this literature implicitly assumes healthy adults maintain an accurate body image. We recently developed a novel, implicit, and quantitative measure of body image - the Body Image Task (BIT). Here, we report a large-scale analysis of performance on this task by healthy adults. In both an in-person and an online version of the BIT, participants were presented with an image of a head as an anchoring stimulus on a computer screen, and told to imagine that the head was part of a mirror image of themselves in a standing position. They were then instructed to judge where, relative to the head, each of several parts of their body would be located. The relative positions of each landmark can be used to construct an implicit perceptual map of bodily structure. We could thus measure the internally-stored body image, although we cannot exclude contributions from other representations. Our results show several distortions of body image. First, we found a large and systematic over-estimation of width relative to height. These distortions were similar for both males and females, and did not closely track the idiosyncrasies of individual participant's own bodies. Comparisons of individual body parts showed that participants overestimated the width of their shoulders and the length of their upper arms, relative to their height, while underestimating the lengths of their lower arms and legs. Principal components analysis showed a clear spatial structure to the distortions, suggesting spatial organisation and segmentation of the body image into upper and lower limb components that are bilaterally integrated. These results provide new insight into the body image of healthy adults, and have implications for the study and rehabilitation of clinical populations.

    Purpose Body image incorporates cognitive and affective components as well as behaviors related to own body perception. This study evaluated the occurrence of body image distortion and its correlates in Korean adolescents. Methods In a school-based cross-sectional survey, a total of 2,117 adolescents were recruited. They filled out self-completing questionnaires on body image distortion, eating attitudes, and behaviors (Eating Attitude Test-26) and related factors. Results Body image distortions were found in 51.8 percent of adolescents. Univariate analyses showed that boys and older adolescents had higher rates of body image distortion. In the multivariate analyses, body image distortion was associated with high risk for eating disorders (odds ratio [OR] =1.69; 95% confidence interval [CI] 1.11–2.58; P=0.015) and being over weight (OR =33.27; 95% CI 15.51–71.35; P<0.001) or obese (OR =9.37; 95% CI 5.06–17.34; P<0.001). Conclusion These results suggest that body image distortion is relatively common in Korean adolescents, which has implications for adolescents at risk of developing eating disorders. PMID:24868156

    This essay discusses the manner in which the human body is developed and transformed into an aesthetically expressive medium. This process entails capitalizing on functions performed by the body schema and, more specifically, on using the perceptual experience (or "image") of the body to consciously form motor schemata. Since this process is…

    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.

    2010-03-01

    This article outlines the expanding approaches to whole-body imaging in oncology focusing on whole-body MRI and comparing it to emerging applications of whole-body CT, scintigraphy, and above all PET CT imaging. Whole-body MRI is widely available, non-ionizing and rapidly acquired, and inexpensive relative to PET CT. While it has many advantages, WBMRI is non-specific and, when compared to PET CT, is less sensitive. This article expands each of these issues comparing individual modalities as they refer to specific cancers.

  9. Low temperature alteration processes affecting ultramafic bodies

    At low temperatures, in the presence of an aqueous solution, olivine and orthopyroxene are not stable relative to the hydrous phases brucite, serpentine and talc. Alteration of dunite and peridotite to serpentine or steatite bodies must therefore proceed via non-equilibrium processes. The compositions of natural solutions emanating from dunites and peridotites demonstrate that the dissolution of forsterite and/or enstatite is rapid compared with the precipitation of the hydrous phases; consequently, dissolution of anhydrous minerals controls the chemistry of such solutions. In the presence of an aqueous phase, precipitation of hydrous minerals is the rate-controlling step. Brucite-bearing and -deficient serpentinites alter at low temperature by non-equilibrium processes, as evidenced by the composition of natural solutions from these bodies. The solutions approach equilibrium with the least stable hydrous phase and, as a consequence, are supersaturated with other hydrous phases. Dissolution of the least stable phase is rapid compared to precipitation of other phases, so that the dissolving mineral controls the solution chemistry. Non-equilibrium alteration of anhydrous ultramafic bodies continues until at least one anhydrous phase equilibrates with brucite, chrysotile or talc. The lowest temperature (at a given pressure) at which this happens is defined by the reaction: 3H2O + 2Mg2SiO4 ??? Mg3Si2O5(OH)4 + Mg(OH)2 (Johannes, 1968, Contrib. Mineral. Petrol. 19, 309-315) so that non-equilibrium alteration may occur well into greenschist facies metamorphic conditions. ?? 1978.

  10. Use of a Cutaneous Body Image (CBI) scale to evaluate self perception of body image in acne vulgaris.

    Skin disorders such as acne, which have significant cosmetic implications, can affect the self-perception of cutaneous body image. There are many scales which measure self-perception of cutaneous body image. We evaluated the use of a simple Cutaneous Body Image (CBI) scale to assess self-perception of body image in a sample of young Arab patients affected with acne. A total of 70 patients with acne answered the CBI questionnaire. The CBI score was correlated with the severity of acne and acne scarring, gender, and history of retinoids use. There was no statistically significant correlation between CBI and the other parameters - gender, acne/acne scarring severity, and use of retinoids. Our study suggests that cutaneous body image perception in Arab patients with acne was not dependent on variables like gender and severity of acne or acne scarring. A simple CBI scale alone is not a sufficiently reliable tool to assess self-perception of body image in patients with acne vulgaris.

    Background Data on the association between body self-perception and eating patterns among adolescents are scarce. This study assessed the association between body image and eating patterns among normal-weight, overweight and obese adolescents. Methods A cross-sectional survey (n = 1231; 12–17 years old) was carried out in the Balearic Islands, Spain. Anthropometry, body image, socio-economic determinants, and food consumption were studied. Results Fifty-one percent of boys and sixty percent of girls that wished to be thinner had less than or equal to 3 eating occasions per day. Overfat girls that wish to be thinner skipped breakfast more frequently than normal-fat girls. Overfat boys and girls that wished a thinner body reported lower consumption of several food groups than normal-fat adolescents and overfat boys satisfied with their own body image (i.e. breakfast cereals, pasta and rice dishes, other oils and fats, high fat foods, soft drinks and chocolates in boys; and dairy products and chocolates in girls).A restriction of Western diet foods and energy intake was associated with a wish to be thinner among overfat adolescents. Conclusions Many overfat boys were satisfied with their body image while practically all overfat girls reported wishing a thinner body. Meal patterns and food consumption were associated with body dissatisfaction and overfat status among adolescents. PMID:24289180

    Cosmetic medical treatments have become increasingly popular over the past decade. The explosion in popularity can be attributed to several factors-the evolution of safer, minimally invasive procedures, increased mass media attention, and the greater willingness of individuals to undergo cosmetic procedures as a means to enhance physical appearance. Medical and mental health professionals have long been interested in understanding both the motivations for seeking a change in physical appearance as well as the psychological outcomes of these treatments. Body image has been thought to play a key role in the decision to seek cosmetic procedures, however, only recently have studies investigated the pre- and postoperative body image concerns of patients. While body image dissatisfaction may motivate the pursuit of cosmetic medical treatments, psychiatric disorders characterized by body image disturbances, such as body dysmorphic disorder and eating disorders, may be relatively common among these patients. Subsequent research on persons who alter their physical appearance through cosmetic medical treatments are likely provide important information on the nature of body image.

    2000-04-10

    Music therapy has developed its practice and research approaches within a qualitative framework more related to humanistic traditions than to medical science. Music medicine has therefore developed as a separate discipline, endeavouring to incorporate the legitimate therapeutic use of music within a medical framework. This paper argues that more extensive communication and collaboration between the methods developed within the music therapy community, and research based on medical science, could lead to a better understanding of the place of music as a therapeutic tool, both as regards its efficacy and its limits. Research has shown that music may influence central physiological variables like blood pressure, heart rate, respiration, EEG measurements, body temperature and galvanic skin response. Music influences immune and endocrine function. The existing research literature shows growing knowledge of how music can ameliorate pain, anxiety, nausea, fatigue and depression. There is less research done on how music, and what type of music, is utilized and administered specifically for optimum effect in specific clinical situations.

Feminist-identified women reported significantly higher body satisfaction than non-feminist women and women who did not identify as feminists but held feminist beliefs. However, feminist-identified women did not differ from non-feminist women in disordered eating. Women holding feminist beliefs and non-feminist women did not differ in body satisfaction. Our findings suggest that self-identification as a feminist may promote positive body image in young adult women, but may be insufficient to change behaviors.

    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

    In this study we assessed different magnetic resonance imaging (MRI) scanning regimes and examined some of the assumptions commonly made for measuring body fat content by MRI. Whole body MRI was used to quantify and study different body fat depots in 67 women. The whole body MRI results showed that there was a significant variation in the percentage of total internal, as well as visceral, adipose tissue across a range of adiposity, which could not be predicted from total body fat and/or subcutaneous fat. Furthermore, variation in the amount of total, subcutaneous, and visceral adipose tissue was not related to standard anthropometric measurements such as skinfold measurements, body mass index, and waist-to-hip ratio. Finally, we show for the first time subjects with a percent body fat close to the theoretical maximum (68%). This study demonstrates that the large variation in individual internal fat content cannot be predicted from either indirect methods or direct imaging techniques, such as MRI or computed tomography, on the basis of a single-slice sampling strategy.

    The scope of this article is to evaluate the body image of adolescents from rural cities and its relationship with nutritional status, sex and the adolescent phase. Adolescents of both sexes participated in the cross-sectional study. Body image was evaluated through the Body Shape Questionnaire (BSQ) and the Figure Rating Scale (FRS) for adolescents. Weight and height were measured for the evaluation of body mass index (BMI). Stages of adolescence were classified by age. Descriptive and inferential statistical analyses were conducted. Four hundred and forty-five adolescents (190 boys and 255 girls), with a mean age of 16.44 comprised the sample. Higher risk of body dissatisfaction was found among overweight and obese participants (BSQ: OR = 3.359 p < 0.001; ESA: OR = 1.572 p = 0.387) and the female sex (BSQ: OR = 3.694 p < 0.001; ESA: OR = 0.922, p = 0.840). Participants from the intermediary and final stages of adolescence revealed a lesser risk of dissatisfaction compared to those from the initial phase. Body dissatisfaction was related to overweight and obesity, to the female sex and to the initial period of adolescence. Intervention research is required to control the factors that influence excessive adolescent body dissatisfaction. PMID:24897479

    Cognitive-affective body image variables and their relation to long-term psychological and sexual functioning were investigated in a community sample of 57 female adult child sexual abuse (CSA) survivors and 47 comparison subjects. The Body-Self Relations Questionnaire and the Body Esteem Scale were administered to assess cognitive-affective body image. Group comparisons indicated that, after controlling for actual weight status, survivors evaluated their health more negatively and reported less body esteem regarding their sexual attractiveness than comparison subjects. Body image variables related to health and sexual attractiveness significantly explained variance on symptom measures that reflect the diverse CSA long-term sequelae. Results suggest the need for careful assessment of body image disturbances and the development of effective interventions targeting body image in the treatment of CSA survivors. PMID:9690192

    Adolescence is a time of tremendous change in physical appearance. Many adolescents report dissatisfaction with their body shape and size. Forming one's body image is a complex process, influenced by family, peers, and media messages. Increasing evidence shows that the combination of ubiquitous ads for foods and emphasis on female beauty and thinness in both advertising and programming leads to confusion and dissatisfaction for many young people. Sociocultural factors, specifically media exposure, play an important role in the development of disordered body image. Of significant concern, studies have revealed a link between media exposure and the likelihood of having symptoms of disordered eating or a frank eating disorder. Pediatricians and other adults must work to promote media education and make media healthier for young people. More research is needed to identify the most vulnerable children and adolescents.

    Objective: To analyze body image in different periods of adolescence. Methods: This cross-sectional study enrolled students aged ten to 19 years old of public schools in small districts of Minas Gerais, Southeast Brazil. The Body Shape Questionnaire (BSQ), the Body Dissatisfaction Assessment Scale for Teenagers and the Silhouette Scale for Teenagers (SST) were used. Adolescence phases were classified according to the subjects' ages. Weight and height were measured in order to calculate the body mass index and the nutritional status. Results were analyzed by logistic regression. Results: The study emolled 531 teenagers (318 females). The average age was 15.6± 2 .2 years and 84.6% were eutrophic. The prevalence of body dissatisfaction varied from 28.9% (BSQ) to 78.9% (SST). Overweight adolescents presented greater dissatisfaction (BSQ: OR 3.66, p<0.001; SST: OR 4.108, p<0.001). Dissatisfaction also occurred for females and those at the early adolescence (p<0.05). Conclusions: A low prevalence of dissatisfaction with the body image was observed among adolescents in small towns of Minas Gerais; however, most of them wished a different silhouette than the current one. The results showed that younger adolescents had higher dissatisfaction than their peers, as well as female and overweighed adolescents. PMID:24676192

    At the age of 4, I incurred a major burn injury that left 45% of my body with permanent scars. Normal clothing covers most of the scars. I was able to reclaim a positive body image through a gradual process of verbal and "body" disclosure. As an adult, I joined a burn survivors' self-help group; as a result of talking with other burn survivors, my self expectations increased. Later, I joined a facilitated group in which nudity and personal growth were the norm. In this group, I was the only person who had experienced a major physical trauma. I replaced my strongly held beliefs that others could not accept my unclothed, burn-injured body with the belief that some persons can, and I came to a personal understanding of why others could not. Fun, exercise, and relaxation led to a reclamation of positive feelings about my unclothed body and allowed my femininity and the character of my body image to emerge and become integrated.

    Body image distress or body dissatisfaction is one of the most common consequences of obesity and overweight. We investigated the neural bases of body image processing in overweight and average weight young women to understand whether brain regions that were previously found to be involved in processing self-reflective, perspective and affective components of body image would show different activation between two groups. Thirteen overweight (O-W group, age = 20.31±1.70 years) and thirteen average weight (A-W group, age = 20.15±1.62 years) young women underwent functional magnetic resonance imaging while performing a body image self-reflection task. Among both groups, whole-brain analysis revealed activations of a brain network related to perceptive and affective components of body image processing. ROI analysis showed a main effect of group in ACC as well as a group by condition interaction within bilateral EBA, bilateral FBA, right IPL, bilateral DLPFC, left amygdala and left MPFC. For the A-W group, simple effect analysis revealed stronger activations in Thin-Control compared to Fat-Control condition within regions related to perceptive (including bilateral EBA, bilateral FBA, right IPL) and affective components of body image processing (including bilateral DLPFC, left amygdala), as well as self-reference (left MPFC). The O-W group only showed stronger activations in Fat-Control than in Thin-Control condition within regions related to the perceptive component of body image processing (including left EBA and left FBA). Path analysis showed that in the Fat-Thin contrast, body dissatisfaction completely mediated the group difference in brain response in left amygdala across the whole sample. Our data are the first to demonstrate differences in brain response to body pictures between average weight and overweight young females involved in a body image self-reflection task. These results provide insights for understanding the vulnerability to body image distress

    Purpose: The objective was to examine how body image affects quality of life in an eating-disorder (ED) clinical sample, a non-ED clinical sample, and a nonclinical sample. We hypothesized that ED patients would show the worst body image quality of life. We also hypothesized that body image quality of life would have a stronger negative association with specific ED-related variables than with other psychological and psychopathological variables, mainly among ED patients. On the basis of previous studies, the influence of gender on the results was explored, too. Patients and methods: The final sample comprised 70 ED patients (mean age 22.65 ± 7.76 years; 59 women and 11 men); 106 were patients with other psychiatric disorders (mean age 28.20 ± 6.52; 67 women and 39 men), and 135 were university students (mean age 21.57 ± 2.58; 81 women and 54 men), with no psychiatric history. After having obtained informed consent, the following questionnaires were administered: Body Image Quality of Life Inventory-Spanish version (BIQLI-SP), Eating Disorders Inventory-2 (EDI-2), Perceived Stress Questionnaire (PSQ), Self-Esteem Scale (SES), and Symptom Checklist-90-Revised (SCL-90-R). Results: The ED patients’ ratings on the BIQLI-SP were the lowest and negatively scored (BIQLI-SP means: +20.18, +5.14, and −6.18, in the student group, the non-ED patient group, and the ED group, respectively). The effect of body image on quality of life was more negative in the ED group in all items of the BIQLI-SP. Body image quality of life was negatively associated with specific ED-related variables, more than with other psychological and psychopathological variables, but not especially among ED patients. Conclusion: Body image quality of life was affected not only by specific pathologies related to body image disturbances, but also by other psychopathological syndromes. Nevertheless, the greatest effect was related to ED, and seemed to be more negative among men. This finding is the

    2012-02-01

    Attitudes towards the body have been largely overlooked as a potential risk factor for adolescent non-suicidal self-injury (NSSI) despite theorizing that a negative body image may play a critical role in the development of this behavior. The current study used structural equation modeling to evaluate the fit of a theoretical model specifying body image as a mediator between negative affect and NSSI in a combined clinical and non-clinical sample of 284 adolescents. The data supported the model, accounted for 21.6% of the variance in NSSI, and body image significantly mediated the relationship between negative affect and NSSI. These findings provide essential preliminary evidence that body image may represent a necessary but not sufficient risk factor for NSSI in adolescents and that treatment for NSSI should consider targeting body-related pathology in addition to emotion regulation. The findings also support including body image within developing etiological models of NSSI.

    ABSTRACT Body dissatisfaction in lesbians is a subject which has traditionally been ignored in the psychological literature on body image and eating disorders. Early feminist theorists and researchers argued that body dissatisfaction in women developed as a way of dealing with the oppression and misogyny they are faced with on a daily basis. However, these theories failed to take issues of race, class, and sexual orientation into account, thereby excluding the experiences of a diversity of women. This article focuses specifically on the lesbian experience and explores how cultural messages about thinness, femininity, and heterosexuality shape lesbians' feelings about their sexuality and about their bodies. Through the inevitable process of internalizing homophobia and fat hatred, both of which are institutionalized ways of keeping heterosexuality and female oppression in place, lesbians may begin to believe that there is something inherently wrong with them and with their bodies. This article explores how the impact of racism, classism, sexism, and homophobia on women may provide a more comprehensive understanding of the cultural forces behind women's dissatisfaction with their bodies.

    The Human Engineering Division of the Armstrong Laboratory (USAF); the Mallinckrodt Institute of Radiology; the Washington University School of Medicine; and the Lister-Hill National Center for Biomedical Communication, National Library of Medicine are sponsoring a working group on electronic imaging of the human body. Electronic imaging of the surface of the human body has been pursued and developed by a number of disciplines including radiology, forensics, surgery, engineering, medical education, and anthropometry. The applications range from reconstructive surgery to computer-aided design (CAD) of protective equipment. Although these areas appear unrelated, they have a great deal of commonality. All the organizations working in this area are faced with the challenges of collecting, reducing, and formatting the data in an efficient and standard manner; storing this data in a computerized database to make it readily accessible; and developing software applications that can visualize, manipulate, and analyze the data. This working group is being established to encourage effective use of the resources of all the various groups and disciplines involved in electronic imaging of the human body surface by providing a forum for discussing progress and challenges with these types of data.

    Body image-related interventions become increasingly important in the treatment of anorexia and bulimia nervosa. Previous studies concerning body image disturbance conducted by means of diverse research methods focused on different components of body image - the perceptive, cognitive-emotional and the behavioral component. However, regarding the etiology, maintenance and treatment of body image disturbance in eating disorders, many questions remain unanswered. An integrative perspective on the different body image components within a theoretical framework as well as the development of specific body image-related interventions according to individual indications would be desirable.

    Body image and eating concerns are prevalent among early adolescent girls, and associated with biological, psychological and sociocultural risk factors. To date, explorations of biopsychosocial models of body image concerns and disordered eating in early adolescent girls are lacking. A sample of 488 early adolescent girls, mean age = 12.35 years (SD = 0.53), completed a questionnaire assessing depressive symptoms, self-esteem, body mass index (BMI), sociocultural appearance pressures, thin-ideal internalization, appearance comparison, body image concerns and disordered eating. Structural equation modelling was conducted to test a hypothetical model in which internalization and comparison were mediators of the effect of both negative affect and sociocultural influences on body image concerns and disordered eating. In addition, the model proposed that BMI would impact body image concerns. Although the initial model was a poor fit to the data, the fit was improved after the addition of a direct pathway between negative affect and bulimic symptoms. The final model explained a large to moderate proportion of the variance in body image and eating concerns. This study supports the role of negative affect in biopsychosocial models of the development of body image concerns and disordered eating in early adolescent girls. Interventions including strategies to address negative affect as well as sociocultural appearance pressures may help decrease the risk for body image concerns and disordered eating among this age group.

    Body dissatisfaction and body image disorders are becoming increasingly prevalent in developing non-Western countries such as China, but there is a lack of research examining the sociocultural factors that in other contexts have been associated with these problems. The current study investigated body dissatisfaction, engagement in body change behaviors, and sociocultural pressures on body image, and the relationships between these variables among 517 adolescent males (N=219) and females (N=298) in China. Females reported greater body dissatisfaction than males, and males reported using strategies to increase their muscle bulk more often than females. Males reported pressure from a variety of sociocultural sources to increase their muscles or weight, while females reported pressure from the media to lose weight. For males body dissatisfaction was predicted by pressure from peers to increase their muscle bulk, while for females pressure to lose weight from peers, adult relatives, and the media was likely to increase body dissatisfaction. Pressure from the media and adult relatives was also predictive of body change behaviors in both males and females. The findings are discussed in relation to previous research in both Western and non-Western contexts.

    Diffusion-weighted MRI is being increasingly used in pediatric body imaging. Its role is still emerging. It is used for detection of tumors and abscesses, differentiation of benign and malignant tumors, and detection of inflamed bowel segments in inflammatory bowel disease in children. It holds great promise in the assessment of therapy response in body tumors, with apparent diffusion coefficient (ADC) value as a potential biomarker. Significant overlap of ADC values of benign and malignant processes and less reproducibility of ADC measurements are hampering its widespread use in clinical practice. With standardization of the technique, diffusion-weighted imaging (DWI) is likely to be used more frequently in clinical practice. We discuss the principles and technique of DWI, selection of b value, qualitative and quantitative assessment, and current status of DWI in evaluation of disease processes in the pediatric body.

    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.

    Obesity is a world-wide epidemic and is associated with multiple comorbidities. The mechanisms underlying the relationship between obesity and adverse health outcomes remain poorly understood. This may be due to several factors including the crude measures used to estimate adiposity, the striking heterogeneity between adipose tissue depots, and the influence of fat accumulation in multiple organs. In order to advance our understanding of fat stores and associated co-morbidities in humans, it will be necessary to image adiposity throughout the body and ultimately also assess its functionality. Large clinical studies are demonstrating the prognostic importance of adipose tissue imaging. Newer techniques capable of imaging fat metabolism and other functions of adipose tissue may provide additional prognostic utility and may be useful in guiding therapeutic interventions.

    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.

    2016-09-01

    Although past studies have highlighted fat talk as relevant to body image disturbance, the majority of these have only investigated the link between fat talk and body esteem, to the exclusion of other body image constructs. One hundred and ninety-nine women completed an online survey measuring levels of appearance-based comparisons, body surveillance, thin ideal internalization, body esteem, and fat talk (FT-body concerns and FT-body comparisons). Results showed that fat talk made a significant contribution in explaining additional variance in body esteem above the other three body image factors, with FT-body concerns in particular making the highest unique contribution. Hierarchical regression analyses suggest that fat talk should be viewed as an independent psychosocial predictor of body esteem in both theoretical and therapeutic contexts. Future research should explore these relationships from a longitudinal perspective, and also clarify the nuances in the relationships by investigating the nature of women's everyday body image experiences.

    Patients with peripheral nerve or spinal cord lesions frequently report perceptual distortions related to position, shape, texture or temperature of the affected areas. This study aimed to describe the phenomenology of such body image alterations during the course of upper limb, lower limb or spinal anaesthetic blocks in patients (n = 36) undergoing orthopaedic surgery. Multimodal sensory testing and assessment of motor function were performed at regular intervals, and the relationship between the reported body image distortions and the progression of sensory and motor impairment was analysed. We found that perceptual changes concerning the shape and size of the deafferented limb occurred in the great majority of patients. In all of them, illusions of swelling, elongation or shortening of the limb coincided with the impairment of warm, cold and/or pinprick sensations, suggesting that thin myelinated Adelta- and/or unmyelinated C-fibres may provide a source of tonic modulation to the limb's cortical representation. Such perceptual alterations of shape and size of body parts differed clearly from postural illusions in terms of frequency, time course and influence of vision. In addition to perceptual changes in the deafferented area, almost half of the patients felt their unanaesthetized lips and/or mouth swelling during the course of upper limb block, suggesting the unmasking of dynamic interactions between somatotopically adjacent cortical representations. Conflicting sensations could co-exist in the patient's body image, such as the illusion of swelling of a limb, which, at the same time, was felt to be missing. The sense of ownership of the deafferented limb was impaired in some cases. These observations show that the perception of body shape and the awareness of its postural variations are built from different plastic models. They also underline the contribution of peripheral afferent activity to the maintenance of a unified body image.

    2014-01-01

    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.

    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.

    Body image disturbance can be enduring and distressing to individuals with eating disorders and effective treatments remain limited. This pilot study evaluated a group-based treatment-BodyWise-developed for use in full and partial hospitalization with patients with anorexia nervosa at low weight. A partial crossover waitlist design was used. BodyWise (N = 50) versus treatment as usual (N = 40) were compared on standardized measures of body image disturbance. Results demonstrated significant improvement in the group compared to treatment as usual for the primary outcome measure (Eating Disorder Examination-Questionnaire Shape Concern subscale) and other manifestations of body image disturbance including body checking and body image quality of life. BodyWise appeared acceptable to participants, and was easy to deliver within the pragmatics of a busy eating disorder service. There is potential for its wider dissemination as a precursor to more active body image interventions.

    The effects of a physical exercise session on state body image and mood were examined. In a cross-over design, participants were randomised to two groups starting either with physical exercise (PE; experimental condition) or with reading a newspaper (RN; control condition). Before and after PE and RN, participants (N = 65) rated their body dimensions using a digital photo distortion technique and indicated their attitudinal body image and mood. Participants' judgements of their 'felt' body dimensions and attitudes toward their own body were affected differently by PE and RN, indicating that participants felt slightly slimmer and were more satisfied with their bodies after PE. Exercise-induced changes in body perception were greater, the higher the pre-experimental drive for thinness, body dissatisfaction and weight/shape concerns were. Especially in those participants with higher body image disturbances, physical exercise can have a reinforcing effect on immediate body image and mood improvement. PMID:20205022

    It is taken for granted that the non-verbal information we acquire from a person's body posture and position affects our perception of others. However, to date human postures have never been described on an empirical level. This study is the first approach to tackle the unexplored topic of human postures. We combined two approaches: traditional behavior observation and modern anthropometric analysis. Photographs of 100 participants were taken, their body postures were transferred to a three dimensional virtual environment and the occurring body angles were measured. The participants were asked to fill in a questionnaire about their current affective state. A principal component analysis with the items of the affect questionnaire (Positive Negative Affect Scales, PANAS) revealed five main factors: aversion, openness, irritation, happiness, and self-confidence. The body angles were then regressed on these factors and the respective postures were reconstructed within a virtual environment. 50 different subjects rated the reconstructed postures from the positive and negative end of the regression. We found the ratings to be valid and accurate in respect to the five factors. PMID:15571090

    Introduction As a chronic disease, End Stage Renal Disease (ESRD) changes the patients’ body and affects their body image negatively. Although the changes in body image are expected in all types of renal replacement therapies, different renal replacement therapy methods could represent different levels of impact on body image. Aim Present study was conducted to examine and compare the level of body-image disturbance between haemodialysis and kidney transplant patients. Materials and Methods This descriptive study was conducted in two teaching hospitals in Tehran, Iran. Using convenient sampling, 84 patients (42 patients under haemodialysis and 42 patients with transplant) were invited to participate in the study. A self-designed questionnaire was developed to examine the level of body-image disturbance. Results Out of 42 haemodialysis patients, 64.3%, 19% and 16.7% of patients reported low, moderate and high level of body-image disturbance respectively. The mean score of body-image disturbance was 21.1±18.3(rang=1–71) in haemodialysis patients. Of 42 transplant patients, 69%, 26.2% and 4.8% reported low, moderate and high level of body-image disturbance respectively. The mean score of body-image disturbance was 17.1±13.3 (rang=1–48). According to the results of independent t-test, difference between mean score of body-image disturbance in two groups was statistically significant (p < 0.05). Conclusion The findings of the present study showed that both haemodialysis and renal transplant patients experienced some levels of body-image disturbance. This problem was more prevalent among haemodialysis patients as compared to kidney transplant ones. We recommend more studies may be conducted in this regard. PMID:27437264

    The prevalence of body image dissatisfaction is considered high in both developed and developing countries. It has been shown that many factors affect the body image dissatisfaction. However, because of the economical and cultural differences, it seems that these affecting factors should be determined in each region. So, the present study was designed to evaluate the prevalence and associated factors with body image dissatisfaction and distortion among Iranian women. Body image perception was analyzed in 500 women through the Stunkard figure rating system. The International Physical Activity Questionnaire was used for assessing physical activity level. The information about age, marital status and socioeconomic status was recorded by general questionnaire. The one-way ANOVA and regression were used for statistical analysis. By increasing the BMI categories from underweight to obesity, participants tended to perceive their body size thinner than real body size. The regression models indicated that the body image distortion was significantly increased with increasing the BMI (p=0.002) and physical activity level (p=0.008). Besides, dissatisfaction by being heavier than ideal was significantly associated with higher BMI (OR (95% CI). 1.21 (1.03, 1.17)). Considering the high prevalence of body image dissatisfaction among Iranian women, for preventing psychological problems and eating disorders, appropriate public health programs for increasing awareness about healthy body size were needed.

    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

    Immigrant adolescents represent a significant and growing proportion of the population in the United States. Yet, little is known about their experiences of body image distortion. This is particularly concerning given that body image distortion has been identified as a significant and modifiable risk factor for a number of mental illnesses, including depression and eating disorders. This study uses multi-level modeling to examine the associations between immigrant generational status, neighborhood immigrant concentration, sex, body dissatisfaction and risk for body image distortion. Data come from the National Longitudinal Study of Adolescent Health and includes 10,962 11-19 year olds (49.6 % female). First generation immigrant females were significantly more likely than 3rd generation-or-later adolescents to experience underweight body image distortion. There was no association between neighborhood immigrant concentration and risk for body image distortion. Body dissatisfaction was associated with greater risk for underweight and overweight body image distortion, with the magnitude of underweight distortion risk significantly greater among 1st generation immigrants. Interventions that encourage the development of a healthy body image have the potential to reduce the onset and duration of body image distortion among immigrant and non-immigrant adolescents.

    The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10-16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants' preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed. PMID:19910269

    Thus far the study of men's body image has been largely restricted to the dimensions of adiposity and muscularity. The aim of this study was to investigate in a systematic way multiple aspects of men's body images, in particular, head hair, body hair, height and penis size, in addition to body weight and muscularity. Questionnaires were completed online by 200 heterosexual men. It was found that men were dissatisfied with all six aspects of their bodies, and worried primarily about body weight, penis size and height. In addition, aspects of weight, muscularity, height and penis size, but not head or body hair, were related to overall appearance self-esteem. It was concluded that men's body image is both multi-faceted and complex.

    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.

    Background Despite the fact that the inflammatory bowel diseases (IBD) and their treatments may affect physical appearance, the effect of IBD on body image is poorly understood. The aims of this study were to determine whether body image dissatisfaction (BID) changes over time in patients with IBD and to examine the demographic and disease-related variables associated with decreased body image. Methods Adults aged 18 and above in the Ocean State Crohn's and Colitis Area Registry with at least 2 years of follow-up were eligible for this study. All patients were enrolled within 6 months of IBD diagnosis and followed prospectively. BID was assessed using a modified version of the Adapted Satisfaction With Appearance (ASWAP) questionnaire. Total ASWAP scores and 2 sub-scores were calculated. To assess for changes over time, general linear models for correlated data were used for continuous outcomes and generalized estimating equations were used for discrete outcomes. Results Two hundred seventy-four patients were studied. BID was found to be stable over time among men and women with IBD despite overall improvements in disease activity. No differences were found in BID according to IBD subtype. Female gender, greater disease activity, higher symptom burden, longer duration of steroid use, dermatologic and musculoskeletal manifestations of IBD, and ileocolonic disease location among patients with Crohn's disease were associated with greater BID. Greater BID was associated with lower health-related quality of life (HRQOL). Conclusions BID remains stable in an incident cohort of IBD despite improved disease activity and is associated with lower HRQOL PMID:25569736

    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.

    Participants maintained a social interaction diary and completed a measure of body image. Body image was found to have three factors, body attractiveness, social attractiveness (how attractive people believed others found them to be), and general attractiveness. For both men and women, self-perceptions of body attractiveness and of social attractiveness were positively related to the intimacy they found in interaction. Self-perceptions of social attractiveness were positively related to women's confidence in social interaction and their perceived influence over interaction, whereas for men, confidence and influence were unrelated to social attractiveness. For both men and women, body image was unrelated to how enjoyable people found interactions to be and was weakly related to how responsive they felt others were to them. For both men and women, body image was also unrelated to how socially active people were and to the relative distribution of same- and opposite-sex interactions.

Body image for this population is a subject that tends to be overlooked in the midst of the cancer experience. This article will examine the complex concept of body image and discuss why female adolescent patients are at such high risk for negative body image. Assessment and care strategies are needed to foster a positive body image, resiliency, and overall well-being. Although survivorship studies may offer insightful information about the effects of the cancer journey on long-term body image, focus should be on prevention and holistic care as part of the treatment itself. The health care team, especially nursing professionals, should acknowledge, recognize, and address this vital issue as a critical part of oncology care.

    The drug-trafficking business has risen tremendously because of the current increased demand for illegal narcotics. The smugglers conceal the drugs in their bodies (body packers) in order to bypass the tight security at international borders. A suspected body packer will normally be sent to the hospital for imaging investigations to confirm the presence of drugs in the body. Radiologists, therefore, need to be familiar with and able to identify drug packets within the human body because they shoulder the legal responsibilities. This pictorial essay describes the characteristic imaging features of drug packets within the gastrointestinal tract. PMID:22415809

    Despite many body changes that accompany the aging process, the extant research is limited on middle age and older adults' body image experiences. The purpose of the present study was to explore how body image is represented for middle age and older adult women. Using thematic analysis, 10 women over the age of 55 were interviewed within an exercise context. The following themes were found: body dissatisfaction, body satisfaction despite ageist stereotypes, neutral body image within cohort, and positive body image characteristics. Negative and positive body images were experienced simultaneously, with neutral experiences expressed as low levels of dissatisfaction. This supports the contention that negative and positive body images exist on separate continuums and neutral body image is likely on the same continuum as negative body image. Programs that foster a social support network to reduce negative body image and improve positive body image in older female populations are needed.

    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.

  10. Attitudinal and perceptual factors in body image distortion: an exploratory study in patients with anorexia nervosa

    2013-01-01

    Background Body image disturbance is a core feature of anorexia nervosa (AN). Attitudinal and cognitive biases as well as fundamental perceptual differences have been hypothesized to play a role in this disturbance. Method This study investigated body image dissatisfaction and distortion, haptic perception and perfectionism in 30 patients with AN and 31 age-matched healthy controls. Participants completed perceptual tasks and self-report measures. Results As predicted, participants with AN scored significantly higher on body dissatisfaction, perfectionism measures and had greater body distortion (as assessed by a body size estimation task). Cognitive–affective factors and perfectionism were highly correlated with body image distortion in AN. No significant differences were found between groups on the generic perception task. Conclusions Findings did not confirm the hypothesis of fundamental perceptual inefficiencies in body image disturbance in individuals with AN. Despite renewed interest in fundamental perceptual factors implicated in body image disturbance, these findings suggest that it continues to be important to focus treatment on cognitive affective biases versus fundamental perceptual inefficiencies.

    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

    The current study examined BMI and body image dissatisfaction as predictors of physical and mental health-related quality of life (HRQL) and psychosocial functioning in a sample of 414 undergraduate students (mean age=21.5, SD=4.9; mean BMI=23.6, SD=5.2). In men and women, higher BMI was correlated with body image dissatisfaction and physical HRQL, but not with any measures of psychosocial functioning, whereas higher body image dissatisfaction was associated with poorer physical HRQL and psychosocial functioning. Furthermore, body image dissatisfaction was observed to mediate the relationship between BMI and physical HRQL in men and women. Interestingly, in this model, higher BMI predicted increased self-esteem. These findings suggest that body image dissatisfaction may be an important target for health interventions. PMID:23726517

  14. Why bodies? Twelve reasons for including bodily expressions in affective neuroscience

    2009-01-01

    Why bodies? It is rather puzzling that given the massive interest in affective neuroscience in the last decade, it still seems to make sense to raise the question ‘Why bodies’ and to try to provide an answer to it, as is the goal of this article. There are now hundreds of articles on human emotion perception ranging from behavioural studies to brain imaging experiments. These experimental studies complement decades of reports on affective disorders in neurological patients and clinical studies of psychiatric populations. The most cursory glance at the literature on emotion in humans, now referred to by the umbrella term of social and affective neuroscience, shows that over 95 per cent of them have used faces as stimuli. Of the remaining 5 per cent, a few have used scenes or auditory information including human voices, music or environmental sounds. But by far the smallest number has looked into whole-body expressions. As a rough estimate, a search on PubMed today, 1 May 2009, yields 3521 hits for emotion × faces, 1003 hits for emotion × music and 339 hits for emotion × bodies. When looking in more detail, the body × emotion category in fact yields a majority of papers on well-being, nursing, sexual violence or organ donation. But the number of cognitive and affective neuroscience studies of emotional body perception as of today is lower than 20. Why then have whole bodies and bodily expressions not attracted the attention of researchers so far? The goal of this article is to contribute some elements for an answer to this question. I believe that there is something to learn from the historical neglect of bodies and bodily expressions. I will next address some historical misconceptions about whole-body perception, and in the process I intend not only to provide an impetus for this kind of work but also to contribute to a better understanding of the significance of the affective dimension of behaviour, mind and brain as seen from the vantage point of bodily

    Dissatisfaction with one's body image is widespread and can have serious health consequences; however, research about its prevalence and correlates in older women is limited. We analyzed data from 75,256 women participating in the Women's Health Initiative Observational Study, a longitudinal study of postmenopausal women's health. Measures used in the study were collected at baseline and/or the third year of follow-up between 1993 and 2002. The majority of participants (83%) in this study were dissatisfied with their bodies because they perceived themselves as heavier than their ideal. Overall, the multiple and significant correlates of body image dissatisfaction explained 36.2% of the variance in the body image dissatisfaction score, with body mass index (BMI) and change in BMI being the two most important contributors to explaining the variance. The results of this study suggest future research should focus on the utility of interventions to reduce dissatisfaction with body image in postmenopausal women that target either maintenance of a lower BMI through diet and exercise, and/or body acceptance. Further, future research should aim to identify factors in addition to body size that drive body image dissatisfaction. PMID:26219698

    To assess the sensitivity of detecting the most commonly encountered foreign bodies in Emergency Radiology using all imaging modalities (conventional radiography, computed tomography, ultrasound, and magnetic resonance imaging). The following materials were inserted into a pig-leg phantom and imaged using conventional radiography, computed tomography, ultrasound, and magnetic resonance imaging: Plastics #1, 2, 3, 5, and compostable plastic; dry and wet wood, aluminum, gravel, glass (tinted and non-tinted), and Salmon and Halibut fish bones. The visibility of plastic is variable on both conventional radiography and computed tomography, depending on composition, but all types of plastic are well visualized on ultrasound. Wood is most easily identified and localized on both computed tomography and ultrasound, is only faintly visible on conventional radiography, and is not well visualized on magnetic resonance imaging. Gravel, glass, and aluminum are well visualized on all modalities, with the exception of magnetic resonance imaging, where there is significant artifact surrounding the foreign body. Fish bones (Halibut and Salmon) are well visualized on conventional radiography, computed tomography, and ultrasound. Conventional radiography and computed tomography are great modalities for detecting foreign bodies of various compositions. Computed tomography is particularly useful at localizing the foreign body and determining its relationship to surrounding structures and its depth of involvement. All foreign bodies are visualized on ultrasound if the location is known and the foreign body is in the plane of the transducer. Magnetic resonance imaging is not helpful in detecting foreign bodies.

    Perceptions of physical appearance, or body image, can affect psychosocial functioning and quality of life (QOL). The present study evaluated the real-world predictive validity of the Body Image Quality of Life Inventory (BIQLI) using Ecological Momentary Assessment (EMA). College women reporting subclinical disordered eating/body dissatisfaction (N=131) completed the BIQLI and related measures. For one week they then completed five daily EMA surveys of mood, social interactions, stress, and eating behaviors on palmtop computers. Results showed better body image QOL was associated with less negative affect, less overwhelming emotions, more positive affect, more pleasant social interactions, and higher self-efficacy for handling stress. Lower body image QOL was marginally related to less overeating and lower loss of control over eating in daily life. To our knowledge, this is the first study to support the real-world predictive validity of the BIQLI by identifying social, affective, and behavioral correlates in everyday life using EMA.

    Past research has obtained mixed findings in relation to gender differences and other factors that shape ideal body image. The current study was designed to investigate these differences further, using a digital body image program to assess body image individually. As expected, females desired a body that was smaller than their current size, whereas males were split between wanting a smaller and larger body. The perceived messages from peers and parents were consistent with the individual's ideal image. Gender differences were also found with ratings of attractiveness and effectiveness. Females rated messages from peers and parents as more important than did males. For both males and females, opposite sex peers were the most important influences, and parents the least important.

    This study experimentally tested the effects of playing with thin dolls on body image and food intake in 6- to 10-year-old Dutch girls (N = 117). Girls were randomly assigned to play with a thin doll, an average-sized doll, or Legos in a no doll control condition. After 10 min, they participated in a taste-test and completed questionnaires about body image. No differences were found between conditions for any of the body image variables. However, girls who played with the average-sized doll ate significantly more food than girls in other exposure conditions. Although no support was found for the assumption that playing with thin dolls influences body image, the dolls directly affected actual food intake in these young girls. PMID:21212808

    Purpose The aim of this study was to analyze the relationships among thought–shape fusion (TSF), specific instruments to assess body image disturbances, and body image quality of life in eating disorder patients in order to improve the understanding of the links between body image concerns and a specific bias consisting of beliefs about the consequences of thinking about forbidden foods. Patients and methods The final sample included 76 eating disorder patients (mean age 20.13 ± 2.28 years; 59 women and seven men). After having obtained informed consent, the following questionnaires were administered: Body Appreciation Scale (BAS), Body Image Quality of Life Inventory (BIQLI-SP), Body Shape Questionnaire (BSQ), Eating Disorders Inventory-2 (EDI-2), State-Trait Anxiety Inventory (STAI), Symptom Checklist-90-Revised (SCL-90-R) and Thought-Shape Fusion Questionnaire (TSF-Q). Results Significant correlations were found between TSF-Q and body image-related variables. Those with higher scores in TSF showed higher scores in the BSQ (P < 0.0001), Eating Disorder Inventory – Drive for Thinness (EDI-DT) (P < 0.0001), and Eating Disorder Inventory – Body Dissatisfaction (EDI-BD) (P < 0.0001). The same patients showed lower scores in the BAS (P < 0.0001). With respect to the psychopathological variables, patients with high TSF obtained higher scores in all SCL-90-R subscales as well as in the STAI. Conclusion The current study shows the interrelations among different body image-related variables, TSF, and body image quality of life. PMID:23055772

    Considering the alarming worldwide increases in eating disorders among adolescents, thought to be linked with body image, this study uses social cognitive theory as a framework to combine the examination of adolescent body image with the topic of mediated characters. The study places a new focus in this realm on favorite television characters, extending past research on general social comparison tendencies or comparisons with unfamiliar mediated models. A survey of 756 students in Grades 7-8 and 10-11 identified their favorite same-gender television characters as well as the adolescents' body image and social comparison with the characters. The survey was accompanied by a content analysis of the favorite characters and their body sizes. Adolescents' favorite television characters were mostly identified as thin or average in body size. The thinner the characters, the more adolescents self-compared with them. The discrepancy between the adolescents' body size and that of their favorite characters significantly and negatively predicted adolescents' body image both directly and indirectly through its relationship with social comparison with the character. The study finds that television characters are important references for adolescents and may serve as targets for social comparison in the context of body image.

    No measures exist that specifically assess cognitive distortions related to body image per se, despite their theoretical and clinical significance. Most cognitive-distortion scales pertain to depression, anxiety, or eating disorders. Accordingly, the 37-item Assessment of Body-Image Cognitive Distortions (ABCD) was developed and validated in this study with a sample of 263 college women. The ABCD samples eight types of distorted thinking related to how persons process information about their physical appearance. Two 18-item parallel forms of the unidimensional measure were also constructed. All forms were highly internally consistent and relatively free from socially desirable responding. Convergent validity for all ABCD forms was established using several standardized measures of body image and eating attitudes. Multiple regression analysis showed that the ABCD was predictable from body-image evaluation, investment, and overweight preoccupation. The ABCD uniquely predicted body-image quality of life and disturbed eating attitudes above and beyond other body-image predictors. Heavier women and White women were more prone to body-image cognitive distortions than were thinner women and Black women. Finally, limitations of this preliminary study, directions for future research, and clinical implications are discussed.

    Optoacoustic imaging is an emerging medical technology that uniquely combines the absorption contrast of optical imaging and the penetration depth of ultrasound. While it is not currently employed as a clinical imaging modality, the results of current research strongly support the use of optoacoustic-based methods in medical imaging. One such application is the diagnosis of the presence of soft tissue foreign bodies. Because many radiolucent foreign bodies have sufficient contrast for imaging in the optical domain, laser-induced optoacoustic imaging could be advantageous for the detection of such objects. Common foreign bodies have been scanned over a range of visible and near infrared wavelengths by using an optoacoustic method to obtain the spectroscopic properties of the materials commonly associated with these foreign bodies. The derived optical absorption spectra compared quite closely to the absorption spectra generated when using a conventional spectrophotometer. By using the probe-beam deflection technique, a novel, pressure-wave detection method, we successfully generated optoacoustic spectroscopic plots of a wooden foreign body embedded in a tissue phantom, which closely resembled the spectrum of the same object obtained in isolation. A practical application of such spectra is to assemble a library of spectroscopic data for radiolucent materials, from which specific characteristic wavelengths can be selected for use in optimizing imaging instrumentation and provide a basis for the identification of the material properties of particular foreign bodies.

    Accurate and objective evaluation of vertebral body deformations represents an important part of the clinical diagnostics and therapy of pathological conditions affecting the spine. Although modern clinical practice is oriented towards threedimensional (3D) imaging techniques, the established methods for the evaluation of vertebral body deformations are based on measurements in two-dimensional (2D) X-ray images. In this paper, we propose a method for automatic measurement of vertebral body deformations in computed tomography (CT) images that is based on efficient modeling of the vertebral body shape with a 3D parametric model. By fitting the 3D model to the vertebral body in the image, quantitative description of normal and pathological vertebral bodies is obtained from the value of 25 parameters of the model. The evaluation of vertebral body deformations is based on the distance of the observed vertebral body from the distribution of the parameter values of normal vertebral bodies in the parametric space. The distribution is obtained from 80 normal vertebral bodies in the training data set and verified with eight normal vertebral bodies in the control data set. The statistically meaningful distance of eight pathological vertebral bodies in the study data set from the distribution of normal vertebral bodies in the parametric space shows that the parameters can be used to successfully model vertebral body deformations in 3D. The proposed method may therefore be used to assess vertebral body deformations in 3D or provide clinically meaningful observations that are not available when using 2D methods that are established in clinical practice.

    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. PMID:27397012

    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.

    Background: Body concerns and its health consequences such as eating disorders and harmful body change activities are mentioned in Asian countries. This study evaluates factors contributing to body image/shape changes in an Iranian population. Methods: In this cross-sectional study we focused on four main body change activity (diet, exercise, substance use, and surgery) and their risk factors such as demographic variables, Body Mass Index (BMI), Media, Body-Esteem, Perceived Socio-cultural Pressure, Body dissatisfaction and, Self-Esteem. Approximately, 1,200 individuals between 14-55 years old participated in this study. We used a multistage sampling method. In each region, the first household was selected at random. The probability of outcomes was estimated from logistic models. Results: About 54.3% of respondents were females. The mean (SD) of age was 31.06 (10.24) years. Variables such as gender, age, BMI, use of media and socio cultural factors as, body dissatisfaction, body-esteem and pressure by relatives were the main factors that influenced body change methods. In particular we have seen that male are 53% less likely to follow surgical treatments, but 125% were more likely to use substances. Conclusions: Investigation of body concern and its health related problem should be assessed in cultural context. For effectiveness of interventional programs and reducing harmful body image/shape changes activities, socio-cultural background should be noted. PMID:24049621

    Affective states, anxiety in particular, have been shown to negatively influence human postural control efficiency as measured by posturographic means, while exposure to a full-length mirror image of one's body exerts a stabilizing effect. We tested the hypothesis that body image concerns and preoccupations would relate negatively to this stabilising effect. Sixty-six healthy students, who screened negative for psychiatric disorders, completed rating scales for anxiety, depression and body image concerns. Posturography recordings of body sway were taken under three conditions: with eyes closed, looking at a vertical bar and looking at a full-length mirror. The Eyes Open/Mirror Stabilometric Quotient [EOMQ=(sway path with eyes closed/sway path looking at the mirror)x100], an index of how much postural control is stabilized by mirror feedback in comparison to the visual vertical bar condition, was significantly inversely related to body image concerns and preoccupations, and to trait anxiety. This finding confirms the impact of emotional factors on human postural control, which warrant further studies. If confirmed in clinical populations characterized by high levels of body image disturbances, e.g. eating disorders, it could lead to developments in the assessment and monitoring of these patients.

    2013-08-01

    The purpose of the current study was to examine whether body dissatisfaction and body image flexibility would be uniquely and significantly associated with disordered eating behavior. In addition, the study examined if body mass index (BMI) moderated the relationships between each of the body image related variables and disordered eating. Two-hundred-fifty-eight female participants completed the web-based survey. Body dissatisfaction and body image flexibility were significantly related to disordered eating behavior, after controlling for ethnicity and BMI, and BMI moderated the relation between body image flexibility and disordered eating. Specifically, for those with low BMI, greater body image flexibility was associated with reduced disordered eating behavior. Body image flexibility was not associated with disordered eating behavior among those with average or high BMI. These results suggest that greater body image flexibility may serve as a protective factor against disordered eating behaviors for those with low BMI.

    In a series of experiments, observers' cognitive and psychophysiological responses to pictorial stimuli were evaluated. In the first experiment, subjects were viewing a set of randomly presented images. After each image presentation, they rates every image on a number of cognitive scales. In the second experiment, images producing certain physiological effects - deactivating, neutral, or activating - were individually selected based on the results of the first experiment and shown to the subjects again. Psychophysiological measurements included electrocardiogram, hand temperature, muscle tension, eye movements, blood oxygen, respiration, and galvanic skin response. Our result indicate that images produced significant emotional changes based on verbal and physiological assessment. The changes were in agreement with the predictions derived from the metric that we developed in a number of cases that exceeded the change level. The direction of changes corresponded to previous findings reported elsewhere.

    The evaluation of vertebral deformations is of great importance in clinical diagnostics and therapy of pathological conditions affecting the spine. Although modern clinical practice is oriented towards the computed tomography (CT) and magnetic resonance (MR) imaging techniques, as they can provide a detailed 3D representation of vertebrae, the established methods for the evaluation of vertebral deformations still provide only a two-dimensional (2D) geometrical description. Segmentation of vertebrae in 3D may therefore not only improve their visualization, but also provide reliable and accurate 3D measurements of vertebral deformations. In this paper we propose a method for 3D segmentation of individual vertebral bodies that can be performed in CT and MR images. Initialized with a single point inside the vertebral body, the segmentation is performed by optimizing the parameters of a 3D deterministic model of the vertebral body to achieve the best match of the model to the vertebral body in the image. The performance of the proposed method was evaluated on five CT (40 vertebrae) and five T2-weighted MR (40 vertebrae) spine images, among them five are normal and five are pathological. The results show that the proposed method can be used for 3D segmentation of vertebral bodies in CT and MR images and that the proposed model can describe a variety of vertebral body shapes. The method may be therefore used for initializing whole vertebra segmentation or reliably describing vertebral body deformations.

    Abstract Background Body image (BI) and body satisfaction may be important in understanding weight loss behaviors, particularly during the postpartum period. We assessed these constructs among African American and white overweight postpartum women. Methods The sample included 162 women (73 African American and 89 white) in the intervention arm 6 months into the Active Mothers Postpartum (AMP) Study, a nutritional and physical activity weight loss intervention. BIs, self-reported using the Stunkard figure rating scale, were compared assessing mean values by race. Body satisfaction was measured using body discrepancy (BD), calculated as perceived current image minus ideal image (BD<0: desire to be heavier; BD>0: desire to be lighter). BD was assessed by race for: BDIdeal (current image minus the ideal image) and BDIdeal Mother (current image minus ideal mother image). Results Compared with white women, African American women were younger and were less likely to report being married, having any college education, or residing in households with annual incomes >$30,000 (all p < 0.01). They also had a higher mean body mass index (BMI) (p = 0.04), although perceived current BI did not differ by race (p = 0.21). African Americans had higher mean ideal (p = 0.07) and ideal mother (p = 0.001) BIs compared with whites. African Americans' mean BDs (adjusting for age, BMI, education, income, marital status, and interaction terms) were significantly lower than those of whites, indicating greater body satisfaction among African Americans (BDIdeal: 1.7 vs. 2.3, p = 0.005; BDIdeal Mother: 1.1 vs. 1.8, p = 0.0002). Conclusions Racial differences exist in postpartum weight, ideal images, and body satisfaction. Healthcare providers should consider tailored messaging that accounts for these racially different perceptions and factors when designing weight loss programs for overweight mothers. PMID:20113143

    A non-acoustic pulse-echo radar monitor is employed in the repetitive mode, whereby a large number of reflected pulses are averaged to produce a voltage that modulates an audio oscillator to produce a tone that corresponds to the heart motion. The antenna used in this monitor generally comprises two flat copper foils, thus permitting the antenna to be housed in a substantially flat housing. The monitor converts the detected voltage to an audible signal with both amplitude modulation and Doppler effect. It further uses a dual time constant to reduce the effect of gross sensor-to-surface movement. The monitor detects the movement of one or more internal body parts, such as the heart, lungs, arteries, and vocal chords, and includes a pulse generator for simultaneously inputting a sequence of pulses to a transmit path and a gating path. The pulses transmitted along the transmit path drive an impulse generator and provide corresponding transmit pulses that are applied to a transmit antenna. The gating path includes a range delay generator which generates timed gating pulses. The timed gating pulses cause the receive path to selectively conduct pulses reflected from the body parts and received by a receive antenna. The monitor output potential can be separated into a cardiac output indicative of the physical movement of the heart, and a pulmonary output indicative of the physical movement of the lung.

The monitor converts the detected voltage to an audible signal with both amplitude modulation and Doppler effect. It further uses a dual time constant to reduce the effect of gross sensor-to-surface movement. The monitor detects the movement of one or more internal body parts, such as the heart, lungs, arteries, and vocal chords, and includes a pulse generator for simultaneously inputting a sequence of pulses to a transmit path and a grating path. The pulses transmitted along the transmit path drive Oh impulse, generator and provide corresponding transmit pulses that are applied to a transmit antenna. The gating path includes a range delay generator which generates timed gating pulses. The timed gating pulses cause the receive path to selectively conduct pulses reflected from the body parts and received by a receive antenna. The monitor output potential can be separated into a cardiac output indicative of the physical movement of the heart, and a pulmonary output indicative of the physical movement of the lung. The impulse generator in the transmit path can be replaced with a pulsed RF generator. 13 figs.

    Purpose The aim of the current study was to analyze the psychometric properties, factor structure, and internal consistency of the Spanish version of the Body Image Quality of Life Inventory (BIQLI-SP) as well as its test–retest reliability. Further objectives were to analyze different relationships with key dimensions of psychosocial functioning (ie, self-esteem, presence of psychopathological symptoms, eating and body image-related problems, and perceived stress) and to evaluate differences in body image quality of life due to gender. Patients and methods The sample comprised 417 students without any psychiatric history, recruited from the Pablo de Olavide University and the University of Seville. There were 140 men (33.57%) and 277 women (66.43%), and the mean age was 21.62 years (standard deviation = 5.12). After obtaining informed consent from all participants, the following questionnaires were administered: BIQLI, Eating Disorder Inventory-2 (EDI-2), Perceived Stress Questionnaire (PSQ), Self-Esteem Scale (SES), and Symptom Checklist-90-Revised (SCL-90-R). Results The BIQLI-SP shows adequate psychometric properties, and it may be useful to determine the body image quality of life in different physical conditions. A more positive body image quality of life is associated with better self-esteem, better psychological wellbeing, and fewer eating-related dysfunctional attitudes, this being more evident among women. Conclusion The BIQLI-SP may be useful to determine the body image quality of life in different contexts with regard to dermatology, cosmetic and reconstructive surgery, and endocrinology, among others. In these fields of study, a new trend has emerged to assess body image-related quality of life. PMID:21403794

    This study examined a range of predictors, based on previous theoretical models, of positive body image in young adult women. Participants were 266 women who completed an online questionnaire measuring body appreciation, activity participation, media consumption, perceived body acceptance by others, self-compassion, and autonomy. Potential mechanisms in predicting body appreciation assessed were self-objectification, social appearance comparison, and thin-ideal internalisation. Results indicated that greater perceived body acceptance by others and self-compassion, and lower appearance media consumption, self-objectification, social comparison, and thin-ideal internalisation were related to greater body appreciation. An integrated model showed that appearance media (negatively) and non-appearance media and self-compassion (positively) were associated with lower self-objectification, social comparison, and thin-ideal internalisation, which in turn related to greater body appreciation. Additionally, perceived body acceptance by others was directly associated with body appreciation. The results contribute to an understanding of potential pathways of positive body image development, thereby highlighting possible intervention targets. PMID:27240100

    Background Body image dissatisfaction (BID) is pervasive among patients presenting for bariatric surgery but significantly improves post-operatively. These findings are based primarily on studies of adults. Objective The objective of this study was to examine changes in BID among adolescents with extreme obesity from baseline/preoperative to 6 and 12 months following bariatric surgery using body size estimation. Setting Pediatric Medical Center. Methods BID was prospectively assessed among 16 adolescent bariatric patients (Mage=16.3±1.2, MBMI=66.2±12.0, 67% female) using a standard visual/perceptual measure [i.e., Stunkard Figure Rating Scale. Participants identified Current and Ideal body size, with a discrepancy score (Current – Ideal) indicating BID. Body size estimation ratings were compared to attitudinal (i.e., IWQOL-Kids: Body Esteem and Self-Perception Profile for Adolescents: Physical Appearance) body image scores, BMI (kg/m2), and Total weight-related quality of life (WRQOL). Results There was a significant reduction in Current body size (7.9 to 6.4, p<.001) from baseline to 6 months but not from 6 to 12 months. Current body size was related to BMI and %EWL but not attitudinal body image at each time point. Smaller Discrepancy (Current – Ideal) was associated with higher Total WRQOL (r=−0.68), with a trend towards significance for Body Esteem (r=−0.65) at 12 months. Conclusions Adolescents undergoing bariatric surgery experience significantly decreased BID within the first 12 months post-surgery, with the most substantial change between baseline and 6 months. Post-operative WRQOL is more closely associated to body size discrepancy than current body size. PMID:22154271

    Understanding the role of body size in relation to the accuracy of body image perception in men is an important topic because of the implications for avoiding and treating obesity, and it may serve as a potential diagnostic criterion for eating disorders. The early research on this topic produced mixed findings. About one-half of the early studies showed that obese men overestimated their body size, with the remaining half providing accurate estimates. Later, improvements in research technology and methodology provided a clearer indication of the role of weight status in body image perception. Research in our laboratory has also produced diverse findings, including that obese subjects sometimes overestimate their body size. However, when examining our findings across several studies, obese subjects had about the same level of accuracy in estimating their body size as normal-weight subjects. Studies in our laboratory also permitted the separation of sensory and nonsensory factors in body image perception. In all but one instance, no differences were found overall between the ability of obese and normal-weight subjects to detect overall changes in body size. Importantly, however, obese subjects are better at detecting changes in their body size when the image is distorted to be too thin as compared to too wide. Both obese and normal-weight men require about a 3%–7% change in the width of their body size in order to detect the change reliably. Correlations between a range of body mass index values and body size estimation accuracy indicated no relationship between these variables. Numerous studies in other laboratories asked men to place their body size into discrete categorizes, ranging from thin to obese. Researchers found that overweight and obese men underestimate their weight status, and that men are less accurate in their categorizations than are women. Cultural influences have been found to be important, with body size underestimations occurring in cultures

    Drawing on focus group discussions, this article explores how young, Finnish university students view the cultural ideals of health and appearance. The young adults noted how body practices aiming at health can turn into unhealthy obsessions. As a result, a healthy-looking body may serve to cover an underlying body image distortion. Health and well-being were defined as appropriate motives for engaging in body projects, while appearance as a motive was questioned. I argue that the current promotion of health may cause individuals to experience pressure to outwardly appear healthy at the cost of neglecting the subjective experience of well-being, and that this may especially influence young women.

    Findings supporting the proposition that dance movement improves a person's body image have been contradictory. Previous work focussed on styles such as ballet, jazz, and modern dance but it is arguable that creative dance movement, with its less structured approach and absence of predetermined performance standards, will have a positive influence on body image. This study examine scores on the Multidimensional Body-Self Relations Questionnaire of 112 women between 18 and 69 years who had been actively participating in creative dance movement courses for periods ranging from two weeks to 16.5 years. Subjects experienced in creative dance movement were more satisfied with their appearance, fitness, and body parts than subjects with less than five years of experience. Differences in evaluation of health were not clearly established. Given this analysis and the potential for wide-spread clinical use of creative dance movement with people having body-image disturbances, empirical research on the relationship between creative dance movement and body image is warranted.

    National and state representative female gymnasts (n = 37), aged initially between 10 and 12 years, completed a mixed longitudinal study over 3.3 years, to investigate the effect of body size on gymnastic performance. Subjects were tested at four-monthly intervals on a battery of measures including structural growth, strength and gymnastic performance. The group were divided into 'high growers' and 'low growers' based on height (> 18 cm or < 14 cm/37 months, respectively) and body mass (> 15 kg or < 12 kg/37 months, respectively) for comparative purposes. Development of gymnastic performance was assessed through generic skills (front and back rotations, a twisting jump and a V-sit action) and a vertical jump for maximum height. The results show that the smaller gymnast, with a high strength to mass ratio, has greater potential for performing skills involving whole-body rotations. Larger gymnasts, while able to produce more power and greater angular momentum, could not match the performance of the smaller ones. The magnitude of growth experienced by the gymnast over this period has a varying effect on performance. While some activities were greatly influenced by rapid increases in whole-body moment of inertia (e.g. back rotation), performance on others like the front rotation and vertical jump, appeared partly immune to the physical and mechanical changes associated with growth.

    Changing the visual body appearance by use of as virtual reality system, funny mirror, or binocular glasses has been reported to be helpful in rehabilitation of pain. However, there are interindividual differences in the analgesic effect of changing the visual body image. We hypothesized that a negative body image associated with changing the visual body appearance causes interindividual differences in the analgesic effect although the relationship between the visual body appearance and analgesic effect has not been clarified. We investigated whether a negative body image associated with changes in the visual body appearance increased pain. Twenty-five healthy individuals participated in this study. To evoke a negative body image, we applied the method of rubber hand illusion. We created an "injured rubber hand" to evoke unpleasantness associated with pain, a "hairy rubber hand" to evoke unpleasantness associated with embarrassment, and a "twisted rubber hand" to evoke unpleasantness associated with deviation from the concept of normality. We also created a "normal rubber hand" as a control. The pain threshold was measured while the participant observed the rubber hand using a device that measured pain caused by thermal stimuli. Body ownership experiences were elicited by observation of the injured rubber hand and hairy rubber hand as well as the normal rubber hand. Participants felt more unpleasantness by observing the injured rubber hand and hairy rubber hand than the normal rubber hand and twisted rubber hand (p<0.001). The pain threshold was lower under the injured rubber hand condition than with the other conditions (p<0.001). We conclude that a negative body appearance associated with pain can increase pain sensitivity.

    Two studies were conducted to examine the association between body image and alcohol use. Of interest was the extent to which alcohol outcome expectancies act as a moderator in this relationship, particularly in women. In Study 1, 421 college students (175 men, 246 women) provided self-report data on body image, social expressiveness expectancies, and average weekly alcohol use; the data were examined using a moderation model. Results showed that women with poor body image and high social expressiveness expectancies reported a significantly greater amount of average weekly alcohol consumption, whereas no such interaction was observed for men. Study 2 tested the same moderation model with 67 female participants; however, this second study utilized an in-lab behavioral measure of alcohol consumption as the outcome variable. The second study replicated results from Study 1, showing that women with overweight body image and alcohol-related high social expressiveness expectancies consumed significantly more beer during a taste rating task than women with other combinations of these variables. Taken together, the results of Studies 1 and 2 indicate that, specifically for women, an overweight body image and positive expectancies about the social, confidence-enhancing benefits of alcohol act as risk factors for excessive drinking.

    Body composition and body mass are pivotal clinical endpoints in studies of welfare diseases. We present a combined effort of established and new mathematical models based on rigorous monitoring of energy intake (EI) and body mass in mice. Specifically, we parameterize a mechanistic turnover model based on the law of energy conservation coupled to a drug mechanism model. Key model variables are fat-free mass (FFM) and fat mass (FM), governed by EI and energy expenditure (EE). An empirical Forbes curve relating FFM to FM was derived experimentally for female C57BL/6 mice. The Forbes curve differs from a previously reported curve for male C57BL/6 mice, and we thoroughly analyse how the choice of Forbes curve impacts model predictions. The drug mechanism function acts on EI or EE, or both. Drug mechanism parameters (two to three parameters) and system parameters (up to six free parameters) could be estimated with good precision (coefficients of variation typically <20 % and not greater than 40 % in our analyses). Model simulations were done to predict the EE and FM change at different drug provocations in mice. In addition, we simulated body mass and FM changes at different drug provocations using a similar model for man. Surprisingly, model simulations indicate that an increase in EI (e.g. 10 %) was more efficient than an equal lowering of EI. Also, the relative change in body mass and FM is greater in man than in mouse at the same relative change in either EI or EE. We acknowledge that this assumes the same drug mechanism impact across the two species. A set of recommendations regarding the Forbes curve, vehicle control groups, dual action on EI and loss, and translational aspects are discussed. This quantitative approach significantly improves data interpretation, disease system understanding, safety assessment and translation across species.

    A short historical survey recalls the main techniques of medical imaging, based on modern physico-chemistry and computer science. Imagery has provided novel visions of the inside of the body, which are not self-obvious but require a training of the gaze. Yet, these new images have permeated the contemporary mind and inspired esthetic ventures. The popularity of these images may be related to their ambiguous status, between real and virtual. The images, reminiscent of Vesalius' De humani corporis fabrica, crosslink art, science and society in a specific way: which role will they play in the "empowerment" of the tomorrow patient?

    Accurate and objective evaluation of vertebral deformations is of significant importance in clinical diagnostics and therapy of pathological conditions affecting the spine. Although modern clinical practice is focused on three-dimensional (3D) computed tomography (CT) and magnetic resonance (MR) imaging techniques, the established methods for evaluation of vertebral deformations are limited to measuring deformations in two-dimensional (2D) x-ray images. In this paper, we propose a method for quantitative description of vertebral body deformations by efficient modelling and segmentation of vertebral bodies in 3D. The deformations are evaluated from the parameters of a 3D superquadric model, which is initialized as an elliptical cylinder and then gradually deformed by introducing transformations that yield a more detailed representation of the vertebral body shape. After modelling the vertebral body shape with 25 clinically meaningful parameters and the vertebral body pose with six rigid body parameters, the 3D model is aligned to the observed vertebral body in the 3D image. The performance of the method was evaluated on 75 vertebrae from CT and 75 vertebrae from T2-weighted MR spine images, extracted from the thoracolumbar part of normal and pathological spines. The results show that the proposed method can be used for 3D segmentation of vertebral bodies in CT and MR images, as the proposed 3D model is able to describe both normal and pathological vertebral body deformations. The method may therefore be used for initialization of whole vertebra segmentation or for quantitative measurement of vertebral body deformations.

    Bilateral prophylactic mastectomy (BPM) can reduce a woman's risk for breast cancer by 80%. Thus, women who are at high risk for familial breast cancer are increasingly opting for BPM as a preventative option. Research indicates that there are psychological benefits to BPM, including a reduction in anxiety about developing breast cancer. The purpose of this integrative review is to summarize the research that has examined the effect of prophylactic mastectomy on women's subsequent body image. Thirteen studies were reviewed. The majority of women were satisfied with their decision. However, the majority of studies indicate that up to one-half of the women suffer a negative effect on body image and changes in sexuality. Knowledge of these findings can improve the practitioner's ability to counsel women regarding this radical decision. Further research, particularly prospective studies, are needed to examine women's body image prior to BPM so that the impact of prophylactic mastectomy can be examined more thoroughly.

    Dieting is widespread among college women despite being ineffective and harmful long term. Intuitive eating is a dieting alternative that teaches eating in response to hunger and satiety cues. It has been associated with improved physical and psychological health and studied in association with various body image dimensions. A sample of college first years completed baseline measurements during an intuitive eating intervention to test the association between intuitive eating and body image discrepancy (BID). BID represents whether a respondent believes her current body is larger or smaller than ideal. Greater BID was negatively associated with intuitive eating (p ≤ .05); participants who believed that their current bodies were larger than ideal were less likely to attend to hunger and satiety cues than participants who expressed little or no BID. These women should be targeted in future weight management interventions in order to avoid negative health outcomes of dieting. PMID:27052661

    The purpose was to compare self-report and psychophysiological assessment techniques in the measurement of emotional response to body image cues. Female college students (n=53; % Caucasian=53.6; M body mass index=26.1 kg/m²) completed the Eating Disorder Inventory (EDI-3) and viewed photos of themselves both unaltered and morphed to simulate weight gain. Response to the photos was assessed by self-report and the affect modulated startle paradigm. EDI-3 Drive for Thinness (DT) and Body Dissatisfaction (BD) scale scores were correlated with startled amplitude for the largest simulated weight gain photo. Startle eye blink amplitude predicted more variance in DT and BD subscales than self-reported response to the image. The affect modulated startle paradigm may provide unique information in the assessment of eating disorder symptomatology that cannot be captured via self-report techniques, and has potential to inform evaluation of treatment outcomes of eating and body image disorders.

    PURPOSE: This study assessed delays in physical growth and sexual maturation, self-esteem and body image in youth with homozygous sickle hemoglobin disease (HgbSS). METHOD: A consecutive sample of 30 subjects age 8 through 19 with homozygous sickle cell disease (hemoglobin SS) and a similar number of control subjects matched for age, race, gender and socioeconomic status and free of chronic illness were examined for height, weight and Tanner staging of sexual development. Subjects also completed the Body Cathexis Scale and Piers-Harris Self-Concept Scale. Assessments were with paired samples t-tests. RESULTS: The subjects with sickle cell disease had significantly lower weights and were shorter than matched control subjects. Sexual development (physical) was also delayed in the sickle cell subjects. The study failed to find significant differences for either body image or self-esteem. CONCLUSIONS: The latency age and adolescent subjects with sickle cell disease had significant delays in physical (height, weight, secondary sexual characteristics) maturation. The study failed to find significant differences in either self-esteem or body image between the two groups. Theoretical constructs from the literature were presented which questioned the belief that these expected delays in physical growth and sexual maturation have an adverse effect upon self-esteem and body image.

    Aim Little is known about body image in children with endocrine conditions. We evaluated body image in children with congenital adrenal hyperplasia (CAH), familial male precocious puberty (FMPP), and Cushing's syndrome (CS). Study design We compared 67 patients (41 CAH, 12 FMPP, 14 CS) age 8–18 years with 55 age-matched controls. Results Patients expressed more weight unhappiness than controls (females: p <0.001; males: p ~ 0.01). This difference remained for females after adjusting for body mass index (BMI) (p ~ 0.03), but not for males (p ~ 0.12). Unhappiness with height and age of appearance was similar between groups. In female patients, higher BMI was a significant predictor of weight unhappiness (p ~ 0.01). Conclusion Adolescents with CAH, FMPP, and CS are at risk for negative body image regarding weight, but not height or age of appearance. Weight unhappiness is partially related to greater weight, but factors unrelated to physical findings seem to contribute to negative body image in female patients. PMID:18825877

    The body image concern (BIC) continuum ranges from a healthy and positive body image, to clinical diagnoses of abnormal body image, like body dysmorphic disorder (BDD). BDD and non-clinical, yet high-BIC participants have demonstrated a local visual processing bias, characterised by reduced inversion effects. To examine whether this bias is a potential marker of BDD, the visual processing of individuals across the entire BIC continuum was examined. Dysmorphic Concern Questionnaire (DCQ; quantified BIC) scores were expected to correlate with higher discrimination accuracy and faster reaction times of inverted stimuli, indicating reduced inversion effects (occurring due to increased local visual processing). Additionally, an induced global or local processing bias via Navon stimulus presentation was expected to alter these associations. Seventy-four participants completed the DCQ and upright-inverted face and body stimulus discrimination task. Moderate positive associations were revealed between DCQ scores and accuracy rates for inverted face and body stimuli, indicating a graded local bias accompanying increases in BIC. This relationship supports a local processing bias as a marker for BDD, which has significant assessment implications. Furthermore, a moderate negative relationship was found between DCQ score and inverted face accuracy after inducing global processing, indicating the processing bias can temporarily be reversed in high BIC individuals. Navon stimuli were successfully able to alter the visual processing of individuals across the BIC continuum, which has important implications for treating BDD. PMID:27003715

    Human figure drawings of patients with severe (n = 85) and mild (n = 38) psoriasis were compared on dimensions of nudity, sexual overemphasis, and omissions of exposed body parts. For female patients significant differences were found for percentages of undressed figures and omissions. For male patients only omissions were significant. When compared to 30 patients with other mild dermatologic conditions, mildly affected psoriatic males drew significantly fewer omissions. Discussion of results focussed on body image concerns of dermatology patients as related to issues of nudity, sexuality, and exhibition of exposed body parts. PMID:7288544

    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

    The present study explores the effects of familiarity on affective responses (pleasure and arousal) to Japanese ad elements, based on the schema incongruity theory. Print ads showing natural scenes (landscapes) were used to create the stimuli (images and words). An empirical study was conducted to measure subjects' affective responses to image-word combinations that varied in terms of incongruity. The level of incongruity was based on familiarity levels, and was statistically determined by a variable called ‘pairing-congruity status’. The tested hypothesis proposed that even highly familiar image-word combinations, when combined incongruously, would elicit strong affective responses. Subjects assessed the stimuli using bipolar scales. The study was effective in tracing interactions between familiarity, pleasure and arousal, although the incongruous image-word combinations did not elicit the predicted strong effects on pleasure and arousal. The results suggest a need for further research incorporating kansei (i.e., creativity) into the process of stimuli selection.

  19. Imaging spectrometry of the Earth and other solar system bodies

    Imaging spectrometry is a relatively new tool for remote sensing of the Earth and other bodies of the solar system. The technique dates back to the late 1970's and early 1980's. It is a natural extension of the earlier multi-spectral imagers developed for remote sensing that acquire images in a few, usually broad spectral bands. Imaging spectrometers combine aspects of classical spectrometers and imaging systems, making it possible to acquire literally hundreds of images of an object, each image in a separate, narrow spectral band. It is thus possible to perform spectroscopy on a pixel-by-pixel basis with the data acquired with an imaging spectrometer. Two imaging spectrometers have flown in space and several others are planned for future Earth and planetary missions. The French-built Phobos Infrared Spectrometer (ISM) was part of the payload of the Soviet Mars mission in 1988, and the JPL-built Near Infrared Mapping Spectrometer (NIMS) is currently en route to Jupiter aboard the Galileo spacecraft. Several airborne imaging spectrometers have been built in the past decade including the JPL-built Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) which is the only such sensor that covers the full solar reflected portion of the spectrum in narrow, contiguous spectral bands. NASA plans two imaging spectrometers for its Earth Observing System, the Moderate and the High Resolution Imaging Spectrometers (MODIS and HIRIS). A brief overview of the applications of imaging spectrometry to Earth science will be presented to illustrate the value of the tool to remote sensing and indicate the types of measurements that are required. The system design for AVIRS and a planetary imaging spectrometer will be presented to illustrate the engineering considerations and challenges that must be met in building such instruments. Several key sensor technology areas will be discussed in which miniaturization and/or enhanced performance through micromachining and nanofabrication may

    Segmentation of anatomical structures and particularly abdominal organs is a fundamental problem for quantitative image analysis in preclinical research. This paper presents a novel approach for whole body segmentation of small animals in a multimodal setting of MR, CT and optical imaging. The algorithm integrates multiple imaging sequences into a machine learning framework, which generates supervoxels by an efficient hierarchical agglomerative strategy and utilizes multiple SVM-kNN classifiers each constrained by a heatmap prior region to compose the segmentation. We demonstrate results showing segmentation of mice images into several structures including the heart, lungs, liver, kidneys, stomach, vena cava, bladder, tumor, and skeleton structures. Experimental validation on a large set of mice and organs, indicated that our system outperforms alternative state of the art approaches. The system proposed can be generalized to various tissues and imaging modalities to produce automatic atlas-free segmentation, thereby enabling a wide range of applications in preclinical studies of small animal imaging.

    OBJECTIVE To comprehend the perception of body image in adolescence. METHODS A qualitative study was conducted with eight focus groups with 96 students of both sexes attending four public elementary school institutions in the city of Rio de Janeiro, Southeastern Brazil, in 2013. An interview guide with questions about the adolescents’ feelings in relation to: their bodies, standards of idealized beauty, practice of physical exercise and sociocultural influences on self-image. In the data analysis we sought to understand and interpret the meanings and contradictions of narratives, understanding the subjects’ context and reasons and the internal logic of the group. RESULTS Three thematic categories were identified. The influence of media on body image showed the difficulty of achieving the perfect body and is viewed with suspicion in face of standards of beauty broadcast; the importance of a healthy body was observed as standards of beauty and good looks were closely linked to good physical condition and result from having a healthy body; the relationship between the standard of beauty and prejudice, as people who are not considered attractive, having small physical imperfections, are discriminated against and can be rejected or even excluded from society. CONCLUSIONS The standard of perfect body propagated by media influences adolescents’ self-image and, consequently, self-esteem and is considered an unattainable goal, corresponding to a standard of beauty described as artificial and unreal. However, it causes great suffering and discrimination against those who do not feel they are attractive, which can lead to health problems resulting from low self-esteem. PMID:25119938

    Many caterpillars have conspicuous eye-like markings, called eyespots. Despite recent work demonstrating the efficacy of eyespots in deterring predator attack, a fundamental question remains: Given their protective benefits, why have eyespots not evolved in more caterpillars? Using a phylogenetically controlled analysis of hawkmoth caterpillars, we show that eyespots are associated with large body size. This relationship could arise because (i) large prey are innately conspicuous; (ii) large prey are more profitable, and thus face stronger selection to evolve such defenses; and/or (iii) eyespots are more effective on large-bodied prey. To evaluate these hypotheses, we exposed small and large caterpillar models with and without eyespots in a 2 × 2 factorial design to avian predators in the field. Overall, eyespots increased prey mortality, but the effect was particularly marked in small prey, and eyespots decreased mortality of large prey in some microhabitats. We then exposed artificial prey to naïve domestic chicks in a laboratory setting following a 2 × 3 design (small or large size × no, small, or large eyespots). Predators attacked small prey with eyespots more quickly, but were more wary of large caterpillars with large eyespots than those without eyespots or with small eyespots. Taken together, these data suggest that eyespots are effective deterrents only when both prey and eyespots are large, and that innate aversion toward eyespots is conditional. We conclude that the distribution of eyespots in nature likely results from selection against eyespots in small caterpillars and selection for eyespots in large caterpillars (at least in some microhabitats).

    Harry, B

    1987-01-01

    The author compared a measure of body image boundary and medically significant bodily experiences between 21 tattooed and 24 nontattooed men incarcerated for violent crimes. Although the tattooed and nontattooed subjects had no significant differences in their body boundary concepts or most other bodily experiences, the tattooed men were found to have a different distribution of scars on their bodies. Upon more detailed examination, it seemed that these different distributions could be explained by the observation that the tattooed subjects were the only ones with self-inflicted cuts. This finding further supports the notion that tattoos, despite their ostensibly decorative quality, may be a form of self-mutilation.

    2010-01-01

    Once medical treatment for gynecological cancer is completed, what happens to patients’ sexuality and body image? Due to the delicate nature of the cancer site, treating this cancer typically affects sexual functioning and body image adversely, making it critical to identify the concerns of these patients and do so in a manner less restrictive than paper-and-pencil assessment. To gain a deeper understanding of the phenomenological experiences in question, we interviewed nine gynecological cancer patients and seven cancer-free women. After implementing a relaxation protocol, we asked each woman to describe her feelings and thoughts on her sexuality and body image in one-on-one interviews. A variety of themes emerged on patients' attitudes and perspectives concerning sexuality and body image following diagnosis and treatment of the cancer. The themes that were considerably different from those of the cancer-free women included decreased sexual functioning and body image, abrupt shifts in self-identity due to loss of physical integrity, and distancing in intimate relationships. Several implications of these findings for clinical practice are discussed, as well as the need to train medical professionals to properly assess these patients’ alterations in sexuality.

    In this paper, a novel system is developed for synthesizing user-specified emotions onto arbitrary input images or videos. Other than defining the visual affective model based on empirical knowledge, a data-driven learning framework is proposed to extract the emotion-related knowledge from a set of emotion-annotated images. In a divide-and-conquer manner, the images are clustered into several emotion-specific scene subgroups for model learning. The visual affection is modeled with Gaussian mixture models based on color features of local image patches. For the purpose of affective filtering, the feature distribution of the target is aligned to the statistical model constructed from the emotion-specific scene subgroup, through a piecewise linear transformation. The transformation is derived through a learning algorithm, which is developed with the incorporation of a regularization term enforcing spatial smoothness, edge preservation, and temporal smoothness for the derived image or video transformation. Optimization of the objective function is sought via standard nonlinear method. Intensive experimental results and user studies demonstrate that the proposed affective filtering framework can yield effective and natural effects for images and videos. PMID:25675469

  1. Empathy and affect: what can empathied bodies do?

    PubMed

    Marshall, George Robert Ellison; Hooker, Claire

    2016-06-01

    While there has been much interest in the apparent benefits of empathy in improving outcomes of medical care, there is continuing concern over the philosophical nature of empathy. We suggest that part of the difficulty in coming to terms with empathy is due to the modernist dichotomies that have structured Western medical discourse, such that doctor and patient, knower and known, cognitive and emotional, subject and object are situated in oppositional terms, with the result that such accounts cannot coherently encompass an emotional doctor, or a patient as knower, or empathy as other than a possession or a trait. This paper explores what, by contrast, a radical critique of the Cartesian world view, in the form of a Deleuzean theoretical framework, would open up in new perspectives on empathy. We extend the framework of emotional geography to ask what happens when people are affected by empathy. We suggest that doctors and patients might be more productively understood as embodied subjects that are configured in their capacities by how they are affected by singular 'events' of empathy. We sketch out how the Deleuzean framework would make sense of these contentions and identify some possible implications for medical education and practice. PMID:26856355

    2014-03-01

    Individuals with a positive body image appreciate their bodies, hold an internal perspective of their bodies, and are satisfied with the functionality of their bodies. Research shows that positive body image is more complex than the absence of body dissatisfaction. Although exercise reduces women's body dissatisfaction, very little research has explored how, or even whether, exercise is associated with positive body image. Therefore, we examined whether exercise frequency was positively related to three aspects of positive body image (body appreciation, internal body orientation, and functional body satisfaction) among 321 college women. Appearance-based exercise motivation (the extent exercise is pursued to influence weight or shape) was hypothesized to moderate these associations. Hierarchical moderated regression analyses showed that exercise frequency was related to higher positive body image, but high levels of appearance-based exercise motivation weakened these relationships. Thus, messages promoting exercise need to de-emphasize weight loss and appearance for positive body image. PMID:24529336

    Optical coherence tomography (OCT) has been widely used to study mammalian embryonic development with the advantages of high spatial and temporal resolutions and without the need for any contrast enhancement probes. However, the limited imaging depth of traditional OCT might prohibit visualization of the full embryonic body. To overcome this limitation, we have developed a new methodology to enhance the imaging range of OCT in embryonic day (E) 9.5 and 10.5 mouse embryos using rotational imaging. Rotational imaging OCT (RI-OCT) enables full-body imaging of mouse embryos by performing multiangle imaging. A series of postprocessing procedures was performed on each cross-section image, resulting in the final composited image. The results demonstrate that RI-OCT is able to improve the visualization of internal mouse embryo structures as compared to conventional OCT.

    2006-01-01

    Comparisons of body attitudes and associated behaviours were undertaken using Malay, Samoan, and Australian female students. The general goal of the research was to determine the degree to which the observed pattern of attitudes and behaviours was attributable to culture. The specific analyses comprised an examination of group differences using standard measures that included the Body Attitudes Questionnaire, the Three-Factor Eating Questionnaire and detailed questions concerning the use of diet and exercise as weight control strategies. The main findings concerned a number of cultural differences, particularly in relation to diet and exercise, that were evident even with the effect of body mass index held constant. These results are interpreted in terms of the efficacy of entrenched cultural beliefs in protecting against introduced, more dominant, cultural values. The Australian sample exhibited the most negative body image, although there was some evidence that Malays and Samoans were influenced by Western ideals of weight and shape. It is proposed that to fully understand the differential meaning of negative body image across cultures and the potential impact of westernisation, both within-group and between-group differences in body size need to be acknowledged.

    Body magnetic resonance (MR) imaging is challenging because of the complex interaction of multiple factors, including motion arising from respiration and bowel peristalsis, susceptibility effects secondary to bowel gas, and the need to cover a large field of view. The combination of these factors makes body MR imaging more prone to artifacts, compared with imaging of other anatomic regions. Understanding the basic MR physics underlying artifacts is crucial to recognizing the trade-offs involved in mitigating artifacts and improving image quality. Artifacts can be classified into three main groups: (a) artifacts related to magnetic field imperfections, including the static magnetic field, the radiofrequency (RF) field, and gradient fields; (b) artifacts related to motion; and (c) artifacts arising from methods used to sample the MR signal. Static magnetic field homogeneity is essential for many MR techniques, such as fat saturation and balanced steady-state free precession. Susceptibility effects become more pronounced at higher field strengths and can be ameliorated by using spin-echo sequences when possible, increasing the receiver bandwidth, and aligning the phase-encoding gradient with the strongest susceptibility gradients, among other strategies. Nonuniformities in the RF transmit field, including dielectric effects, can be minimized by applying dielectric pads or imaging at lower field strength. Motion artifacts can be overcome through respiratory synchronization, alternative k-space sampling schemes, and parallel imaging. Aliasing and truncation artifacts derive from limitations in digital sampling of the MR signal and can be rectified by adjusting the sampling parameters. Understanding the causes of artifacts and their possible solutions will enable practitioners of body MR imaging to meet the challenges of novel pulse sequence design, parallel imaging, and increasing field strength.

The combination of these factors makes body MR imaging more prone to artifacts, compared with imaging of other anatomic regions. Understanding the basic MR physics underlying artifacts is crucial to recognizing the trade-offs involved in mitigating artifacts and improving image quality. Artifacts can be classified into three main groups: (a) artifacts related to magnetic field imperfections, including the static magnetic field, the radiofrequency (RF) field, and gradient fields; (b) artifacts related to motion; and (c) artifacts arising from methods used to sample the MR signal. Static magnetic field homogeneity is essential for many MR techniques, such as fat saturation and balanced steady-state free precession. Susceptibility effects become more pronounced at higher field strengths and can be ameliorated by using spin-echo sequences when possible, increasing the receiver bandwidth, and aligning the phase-encoding gradient with the strongest susceptibility gradients, among other strategies. Nonuniformities in the RF transmit field, including dielectric effects, can be minimized by applying dielectric pads or imaging at lower field strength. Motion artifacts can be overcome through respiratory synchronization, alternative k-space sampling schemes, and parallel imaging. Aliasing and truncation artifacts derive from limitations in digital sampling of the MR signal and can be rectified by adjusting the sampling parameters. Understanding the causes of artifacts and their possible solutions will enable practitioners of body MR imaging to meet the challenges of novel pulse sequence design, parallel imaging, and increasing field strength. ©RSNA, 2015 PMID:26207581

  9. Listening-touch, Affect and the Crafting of Medical Bodies through Percussion

    PubMed Central

    2015-01-01

    The growing abundance of medical technologies has led to laments over doctors’ sensory de-skilling, technologies viewed as replacing diagnosis based on sensory acumen. The technique of percussion has become emblematic of the kinds of skills considered lost. While disappearing from wards, percussion is still taught in medical schools. By ethnographically following how percussion is taught to and learned by students, this article considers the kinds of bodies configured through this multisensory practice. I suggest that three kinds of bodies arise: skilled bodies; affected bodies; and resonating bodies. As these bodies are crafted, I argue that boundaries between bodies of novices and bodies they learn from blur. Attending to an overlooked dimension of bodily configurations in medicine, self-perception, I show that learning percussion functions not only to perpetuate diagnostic craft skills but also as a way of knowing of, and through, the resource always at hand; one’s own living breathing body.

    2013-01-01

    Background Genetic testing among women for BRCA1/2 mutation can have various psychological effects, such as those focusing on body image. The aim of this study was to examine the psychometric properties of a generic scale assessing breast and body image (BBIS) in healthy women tested for BRCA1/2 mutations. Methods A Dutch body image scale focusing on both general and breast-related body image was translated into French. It was presented to a French cohort of female cancer-free BRCA1/2 mutation carriers and non-carriers (N = 568). The psychometric properties of the scale were studied by assessing its dimensional and factorial structure, internal consistency, construct-related validity, and external validity. Results The scale was found to be a satisfactory psychometric tool for assessing both body image and breast image. The three main dimensions which emerged were classified under the headings “values attached to body image”, “satisfaction with body image and perceived attractiveness”, and “satisfaction with breasts”. The BBIS scores were not significantly associated with the participants’ socio-demographic characteristics or their BRCA1/2 mutation carrier status, but significant associations were observed between these scores and the women’s medical and behavioural characteristics. Conclusions The BBIS is a generic tool which can be used to assess body image in either affected or unaffected women. The scale will have to be administered to other populations in order to confirm its validity. PMID:23680028

  12. Living into the imagined body: how the diagnostic image confronts the lived body.

    2013-06-01

    In this paper I will show how the medical image, presented to the patient by the physician, participates in medicine's cold culture of abstraction, objectification and mandated normativity. I begin by giving a brief account of the use of anatomical imaging since the Renaissance to show how images have historically functioned in contrast to how they are currently used in medical practice. Next, I examine how contemporary medical imaging techniques participate in a kind of knowledge production that objectifies the human body. Finally, I elucidate how physicians ought to place the medical image within the context of the lived body so as to create a healing relationship with the patient. In all this I hope to show that the medical image, far from a piece of objective data, testifies to the interplay of particular beliefs, practices and doctrines contemporary medicine holds dear. To best treat her patient, the physician must appreciate the influence of these images and appropriately place them within the context of the patient's lived experience.

    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.

    In the present study, 101 women and 106 men from a community sample of British adults completed the Body Appreciation Scale (BAS), along with a battery of individual difference measures and demographics. Contrary to previous findings, there were no sex differences in BAS scores, either before or after controlling for individual differences in other measures. The results also showed that, moderating for participants' sex, self-assessed attractiveness, educational qualifications, neuroticism, extraversion, and BMI were all significant predictors of body appreciation. In addition, higher media consumption and higher (male-stereotypic) instrumentality were associated with, but did not predict, higher body appreciation. These results are discussed in relation to the extant work on body image.

    This study was undertaken to determine whether perceptions about body image and size vary by body mass index (BMI) and demographic factors among American Indian children in the Southwestern United States. We surveyed 1,996 American Indian schoolchildren in the fifth grade (mean age 10.5 +/- 0.7 years) at eleven rural elementary schools. Heights and weights were measured using standard protocol. Multiple linear regression models were developed for preferred body shape, desired body shape, and body satisfaction to determine association with demographic and physical factors. Results from multiple linear regression modeling indicated that BMI and gender influence body satisfaction, with heavier children and girls being less satisfied with their bodies (P<.001 and P<.05, respectively). Geographic isolation and lack of amenities in the home did not appear to affect body satisfaction or messages from others about being too fat or thin; however, geographically isolated students were more likely to choose a larger body shape as best looking. Girls of appropriate weight were 2.2 times more likely than boys to have been told they were too fat. Sixty-one percent of all students surveyed had tried to lose weight. These findings, although similar to those for non-Hispanic Whites of the same age, are contrary to prevailing ideas that American Indians value obesity. In fact, we observed a high level of body dissatisfaction among children of appropriate weight, particularly girls, and prevalent dieting across all weight categories and both genders.

    Abstract Background Cancer and its treatment can significantly affect appearance and body integrity. A number of studies have explored the impact of cancer and its treatment on body image, primarily in head and neck and breast cancer. The aim of this pilot study was to examine the construct of body image dissatisfaction and its measurement using a single question in patients with advanced cancer. Methods Outpatients with advanced cancer were recruited (n=81). Assessments included Body Image Scale (BIS), Appearance Schema Inventory (ASI-R), Edmonton Symptom Assessment System (ESAS) with a total symptom distress score (TSDS) and two subscales scores (physical distress [PHS] and psychological distress [PSS]), Hospital Anxiety Depression Scale (HADS), and one question assessing the overall appearance satisfaction from the Multidimensional Body-Self Relations Questionnaire (MBSRQ). We also asked patients to rate the body image changes importance compared with five symptoms (pain, fatigue, depression, insomnia, lack of appetite). Results Forty-seven (58%) patients had a BIS score >10 (body image dissatisfaction) with a median of 11 (first–third quartiles, Q1–Q3; 5–16) and a median ASI-R of 3.1 (Q1–Q3; 2.8–3.5). Sensitivity and specificity of ≤3 for body image dissatisfaction in the single overall appearance question using the BIS as a standard was 0.70 and 0.71, respectively. BIS score was significantly correlated with ASI-R (r=0.248; p=0.025), age (r=−0.225; p=0.043), HADS-A (r=0.522, p<0.001), HADS-D (r=0.422, p<0.001), PSS score (r=0.371, p=0.001), PHS score (r=0.356, p=0.001), TSDS score (r=0.416, p<0.001), and the overall appearance question (MBSRQ; r=−0.449, p<0.001). Conclusion Body image dissatisfaction was frequent and associated with symptom burden. A single item ≤3 has a sensitivity of 70% for body image satisfaction screening. PMID:25188590

    The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

    The presence of partial melt in the Earth's crust causes a decrease in density, and hence a density contrast, that generates a potential field anomaly. Gravimetric techniques can quantify such an anomaly and invert its signature to produce a subsurface density distribution model, from which images of anomalous density bodies can be isolated. Here, we present a 3D gravimetric image of four deep-rooted negative density bodies in the Central Volcanic Zone of the Andes in southern Bolivia, which we interpret to contain partial melt. The underlying gravimetric data were obtained by the combination of 143 new with 60 existing observation from previous regional surveys. The survey covers an area of ~5000 km2 that comprises the Central Andean Bouguer anomaly minima of about -450 μGal. After standard data reduction, the local residual gravity signal was inverted using a priori determined plausible density contrasts (±50 to ±300 kg m-3). The inversion routine builds a subsurface model (defined by the 3D aggregation of parallel-piped cells) based on a controlled 'growth' process of anomalous density bodies by means of an exploratory approach. Non-uniqueness is addressed by favouring solutions that balance minimum residuals and minimum number of anomalous bodies with minimum anomalous mass. Within the range of assumed density contrasts, all inversion models show the presence of the deep-rooted low-density bodies, providing a significant confidence level to the inversion results. Our favoured 3D model of the anomalous bodies is obtained from a negative density contrast of 150 kg m-3 that corresponds to <30 vol% partial melt of dacitic composition. These partially molten bodies appear to connect the Altiplano-Puna Magma Body (AMPB) at ~20 km depth, to shallower (~5 km) pre-eruption levels beneath the Altiplano-Puna Volcanic Complex (APVC). One of the bodies is located beneath a large on-going ground uplift centred at Uturuncu volcano and the modelled ground deformation source

    Advantaged socioeconomic position (SEP) is associated with lower body image satisfaction (BIS) among women. However, motherhood and social trajectory (an individual's path from childhood SEP to adulthood SEP) could change this relationship. We aimed to assess the association between social trajectory and BIS immediately before getting pregnant in primiparous and multiparous mothers of a birth cohort. The birth cohort Generation XXI was assembled after delivery, in Porto, in 2005-2006. This analysis includes 5,470 women. Women's and their parents' education were used as indicators of adulthood and childhood SEP, respectively. Social trajectory was classified as stable-high, upward, stable-low, downward, according to both education variables. BIS was assessed with Stunkard silhouettes immediately after birth as the difference between perceived body size before the index pregnancy and ideal body size. Odds ratios (OR) between social trajectory and BIS were computed using multinomial logistic regression (women satisfied with body image were the outcome reference category), adjusting for age and prepregnancy body mass index. In primiparous women, no association was found between childhood SEP, adulthood SEP or social trajectory and feeling too small or too large regarding their ideal figure. Multiparous women with a downward social trajectory presented a higher likelihood of dissatisfaction [too small: adjusted OR 2.21, 95 % confidence interval (95 % CI) 1.10-4.46; too large: adjusted OR 1.64, 95 % CI 1.07-2.51]. Downward social trajectory was associated with a higher likelihood of dissatisfaction with body image in multiparae, while there was no effect among primiparae. PMID:25359096

  2. Positron Emission Tomography (PET) for Imaging Body Chemistry

    PET is a nuclear medicine technology for imaging chemical processes as they are occurring in the human body. This distinguishes it from conventional radiographic and NMR imaging, which depict anatomic changes that generally occur secondary to chemical changes. As our knowledge about human genomics and molecular biology increases and as we develop new approaches to therapy based on this biochemical information, it becomes increasingly important to be able to image important chemical processes occurring in vivo. Methods exist for imaging metabolic rates for energy utilization, cellular proliferation, and protein synthesis. The sending and receiving function of neurotransmitters can be imaged to test for mismatch in their communication function. Gene transfection can be imaged with PET reporters. All of these approaches allow the physician to better select the appropriate treatment for an individual patient, rather than basing treatment on historical experience for a population of similar patients. The technology for PET requires synthesis of positron emitting radioactive molecules, most commonly labeled with C-11 (20.4m) and F-18 (109.8 m) which are made on site with an accelerator. FNAL was involved in developing new RFQ technology for making PET isotopes. The technology also requires better imaging technology, including scintillators, and more robust algorithms for image reconstruction and data analysis.

    The sizes of nuclear bodies and other nuclear structures are normally no more than a few hundred nanometers. This size is below the resolution limit of light microscopy and thus requires electron microscopy for direct observation. Recent developments in super-resolution microscopy have extended the resolution of light microscopy to beyond 100 nm. Here, we describe a super-resolution technique, gated STED, for the analysis of the structure of nuclear bodies, with emphasis on the sample preparation and other technical tips that are important to obtain high-quality super-resolution images.

    Nutritional disorders are now spreading worldwide both in developed and developing countries. Body image ideals and dissatisfaction have been linked to a number of poor health outcomes, including nutritional disorders. While previous studies have offered insight into weight status and body image perception of immigrants in North America, very few studies have analysed these aspects in migrants from Africa to Europe. Our review examines the effects of the migration process on beauty ideals and body dissatisfaction in African immigrants in Europe compared to residents in their own countries. The PubMed, PsycINFO and Google Scholar databases were searched for studies published from January 2000 till November 2015. Of the 730 titles identified, 26 met the inclusion criteria and were included in the present review. Among African residents, the body preferences depend on the country of residence and their socio-cultural status. Ethnic groups living in great isolation or with low incomes still have an ancestral idea of beauty, preferring a shapely body. However ethnic groups living in urban areas are moving toward Westernization of beauty ideals, preferring underweight or normal weight bodies. This review highlights that both residents and migrants are at high risk of nutritional disorders due to the adoption of Western beauty ideals. The results suggest that body dissatisfaction and BMI are increasing from Southern Africa to Europe according to a geographical gradient (described for females by Spearman's coefficient and linear regression, respectively). We emphasize the need for monitoring of the weight and psychological status of immigrants and the development of specific preventive strategies in European countries. PMID:27558365

    As investigators consider approaching the challenge of MR imaging at field strengths above 3T, do they follow the same paradigm, and continue to work around the same problems they have encountered thus far at 3T, or do they explore other ways of answering the clinical questions more effectively and more comprehensively? The most immediate problems of imaging at ultrahigh field strength are not unfamiliar, as many of them are still pressing issues at 3T: radiofrequency coils, B1 homogeneity, specific absorption rate, safety, B0 field homogeneity, alterations in tissue contrast, and chemical shift. In this article, these issues are briefly reviewed in terms of how they may affect image quality at field strengths beyond 3T. The authors propose various approaches to overcoming the challenges, and discuss potential applications of ultrahigh field MR imaging as it applies to specific abdominal, pelvic, peripheral vascular, and breast imaging protocols.

    Background Body image is a critical psychosocial issue for patients facing treatment for oral cancer yet there is limited research conducted in this area. This study utilizes a multidimensional approach to body image assessment and evaluates relationships between body image, demographic, health, and psychosocial variables. Methods Newly diagnosed patients with oral cancer completed self-report questionnaires and a structured clinical interview. Results Most participants identified current and/or future body image concerns primarily related to impending surgery. Adequate psychometric properties were demonstrated on a range of body image measures. Depression was the strongest and most consistent predictor of body image outcomes. Conclusions Preliminary evidence supports the importance of evaluating body image concerns in oral cancer patients prior to surgical intervention. Our findings have implications for developing validated body image tools and can be used to guide psychosocial interventions targeting body image disturbance. PMID:19626634

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.

    This paper reports on the perception of changing body image and well-being for patients who had undergone plastic surgery following massive weight loss. The exploratory, qualitative study was undertaken with 20 patients from one teaching hospital in the south of England. Semi-structured interviews were carried out and a thematic analysis of the data undertaken. The results provide important insights regarding body contouring influencing body image change and the adjustment process involved. The ability to pursue self-esteem and the accruing social benefits is emphasized in the interrelated sub themes including social acceptance, undoing depression and sexual vitality. Body contouring surgery following massive weight loss appears to facilitate improvement in body image and well-being. Adjustment to the changing body image is both empowering and challenging. Supportive educational programmes need to be developed to assist this transition to a more positive body image and appreciation; these could usefully include access to and involvement with patient support groups.

    Susceptibility artifacts due to metallic foreign bodies may interfere with interpretation of magnetic resonance (MR) imaging studies. Additionally, migration of metallic objects may pose a risk to patients undergoing MR imaging. Our purpose was to investigate prevalence, underlying cause, and diagnostic implications of susceptibility artifacts in small animal MR imaging and report associated adverse effects. MR imaging studies performed in dogs and cats between April 2008 and March 2010 were evaluated retrospectively for the presence of susceptibility artifacts associated with metallic foreign bodies. Studies were performed using a 1.0 T scanner. Severity of artifacts was graded as 0 (no interference with area of interest), 1 (extension of artifact to area of interest without impairment of diagnostic quality), 2 (impairment of diagnostic quality but diagnosis still possible), or 3 (severe involvement of area of interest resulting in nondiagnostic study). Medical records were evaluated retrospectively to identify adverse effects. Susceptibility artifacts were present in 99/754 (13.1%) of MR imaging studies and were most common in examinations of the brachial plexus, thorax, and cervical spine. Artifacts were caused by identification microchips, ballistic fragments, skin staples/suture material, hemoclips, an ameroid constrictor, and surgical hardware. Three studies were nondiagnostic due to the susceptibility artifact. Adverse effects were not documented.

    Objectives To prospectively investigate associations between overweight and depressive symptoms in Asian and Hispanic adolescents. Methods Data included 780 Hispanic and 375 Asian students. Structural equation model was used to prospectively explore moderation effects of gender, ethnicity, and acculturation on associations of overweight, body image dissatisfaction, and depressive symptoms. Results Significant mediation effect was found only in Asian girls (mediation effect=0.16, P<0.05) and girls with high acculturation (mediation effect=0.17, P<0.05). Overweight significantly predicted higher body image dissatisfaction, which in turn was significantly related to depressive symptoms. Conclusion Our findings help understanding the association of overweight and experience of depressive symptoms. PMID:20218759

    THz radiation can penetrate through many nonpolar dielectric materials and can be used for nondestructive/noninvasive sensing and imaging of targets under nonpolar, nonmetallic covers or containers. Thus using THz systems to "see through" concealing barriers (i.e. packaging, corrugated cardboard, clothing) has been proposed as a new security screening method. Objects that can be detected by THz include concealed weapons, explosives, and chemical agents under clothing. Passive THz imaging system can detect THz wave from human body without transmit any electromagnetic wave, and the suspicious objects will become visible because the THz wave is blocked by this items. We can find out whether or not someone is carrying dangerous objects through this image. In this paper, the THz image enhancement, segmentation and contour extraction algorithms were studied to achieve effective target image detection. First, the terahertz images are enhanced and their grayscales are stretched. Then we apply global threshold segmentation to extract the target, and finally the targets are marked on the image. Experimental results showed that the algorithm proposed in this paper can extract and mark targets effectively, so that people can identify suspicious objects under clothing quickly. The algorithm can significantly improve the usefulness of the terahertz security apparatus.

    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. PMID:23600733

    The amount of patients presenting at the emergency hospitals with retained rectal foreign bodies appears recently to have increased. Foreign objects retained in the rectum may result from direct introduction through the anus (more common) or from ingestion. Affected individuals often make ineffective attempts to extract the object themselves, resulting in additional delay of medical care and potentially increasing the risk of complications. The goals of radiological patient assessment are to identify the type of object retained, its location, and the presence of associated complications. Plain film radiographs still play an important role in the assessment of retained rectal foreign bodies. PMID:25639182

    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.

    This study investigated the messages individuals receive from their partners about their bodies and their perceived impact on body image and sexual well-being. 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. PMID:27085111

    Background: Eating disorder is one of the most common health problems with clinical and psychological consequences, which can affect body image in cancer patients. Similar studies in this area for checking the status of this disorder and its relevance with body image in patients with cancer are limited. Therefore, this study was designed with the aim of determination of eating disorders in patients with cancer and their relevance with body image. Materials and Methods: The research was a cross-correlation study. It was carried out in Sayed-Al-Shohada Hospital affiliated to the Isfahan University of Medical Sciences in 2013. Two hundred and ten patients with cancer were selected and were asked tocomplete the demographic and disease characteristics questionnaire, the Multidimensional Body-Self Relations Questionnaire (MBSRQ), and eating disorders questionnaire. SPSS statistical software, version 14 was used for statistical analysis’-Test, analysis of variance (ANOVA), and Pearson correlation coefficient were used for analyzing the obtained data. Results: The mean values of age, body mass index (BMI), and duration of illness were 48.2 ± 13.20 years, 24.6 ± 4.6kg/m2, and 25.64 ± 21.24months, respectively. Most patients were married (87%), without university education (96%), unemployed (67%), and with incomes below their requirement (52%). Most patients were diagnosed with breast cancer (36.5%). They received chemotherapy as the main treatment (56.2%). In addition, mean ± SD of eating disorders and body image were 12.84 ± 4.7 and184.40 ± 43.68, respectively. Also, 49.7% of patients with cancer had an eating disorder. Among these, 29% had experiences of anorexia and 20.7% had bulimia. There was a significant negative correlation between the score of body image and eating disorders (r = −0.47, P = 0.01). Conclusions: Findings of this study showed that most patients with cancer had experienced symptoms of eating disorders. This may lead to a negative impact on

    2012-01-01

    Background Available data suggest that body dissatisfaction is common during pregnancy and may even be a precursor to post-natal depression. However, in order to accurately identify at-risk women, it is essential to first establish that body image measures function appropriately in pregnant populations. Our study examines the suitability of the Body Attitudes Questionnaire (BAQ) for measuring body dissatisfaction among pregnant women by comparing the psychometric functioning of the BAQ: (1) across key phases of pregnancy, and (2) between pregnant and non-pregnant women. Methods A total of 176 pregnant women from Melbourne, Victoria filled out a questionnaire battery containing demographic questions and the Body Attitudes Questionnaire at 16, 24, and 32 weeks during pregnancy. A comparison group of 148 non-pregnant women also completed the questionnaire battery at Time 1. Evaluations of the psychometric properties of the BAQ consisted of a series of measurement invariance tests conducted within a structural equation modelling framework. Results Although the internal consistency and factorial validity of the subscales of the BAQ were established across time and also in comparisons between pregnant and non-pregnant women, measurement invariance tests showed non-invariant item intercepts across pregnancy and also in comparison with the non-pregnant subgroup. Inspection of modification indices revealed a complex, non-uniform pattern of differences in item intercepts across groups. Conclusions Collectively, our findings suggest that comparisons of body dissatisfaction between pregnant and non-pregnant women (at least based on the BAQ) are likely to be conflated by differential measurement biases that serve to undermine attempts to accurately assess level of body dissatisfaction. Researchers should be cautious in assessments of body dissatisfaction among pregnant women until a suitable measure has been established for use in this population. Given the fact that body

    The purpose of this study was to evaluate diffuse affectations in the liver using texture image processing techniques. Ultrasound diagnose equipments are the election of choice to be used in space environments as they are free from hazardous effects on health. However, due to the need for highly trained radiologists to assess the images, this imaging method is mainly applied on focal lesions rather than on non-focal ones. We have conducted a clinical study on 72 patients with different degrees of chronic hepatopaties and a group of control of 18 individuals. All subjects' clinical reports and results of biopsies were compared to the degree of affectation calculated by our computer system , thus validating the method. Full statistical results are given in the present paper showing a good correlation (r=0.61) between pathologist's report and analysis of the heterogenicity of the processed images from the liver. This computer system to analyze diffuse affectations may be used in-situ or via telemedicine to the ground.

    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. PMID:24623160

    Static photographs are currently the most often employed stimuli in research on social perception. The method of photograph acquisition might affect the depicted subject's facial appearance and thus also the impression of such stimuli. An important factor influencing the resulting photograph is focal length, as different focal lengths produce various levels of image distortion. Here we tested whether different focal lengths (50, 85, 105 mm) affect depicted shape and perception of female and male faces. We collected three portrait photographs of 45 (22 females, 23 males) participants under standardized conditions and camera setting varying only in the focal length. Subsequently, the three photographs from each individual were shown on screen in a randomized order using a 3-alternative forced-choice paradigm. The images were judged for attractiveness, dominance, and femininity/masculinity by 369 raters (193 females, 176 males). Facial width-to-height ratio (fWHR) was measured from each photograph and overall facial shape was analysed employing geometric morphometric methods (GMM). Our results showed that photographs taken with 50 mm focal length were rated as significantly less feminine/masculine, attractive, and dominant compared to the images taken with longer focal lengths. Further, shorter focal lengths produced faces with smaller fWHR. Subsequent GMM revealed focal length significantly affected overall facial shape of the photographed subjects. Thus methodology of photograph acquisition, focal length in this case, can significantly affect results of studies using photographic stimuli perhaps due to different levels of perspective distortion that influence shapes and proportions of morphological traits.

    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.

    Visual art because of its artistic context can be related to the general idea of providing alternative perceptual experiences. However, research examining the neural basis of art beyond the paradigm of beauty has been neglected. This study seeks to determine how the perception of a body in an artwork can be distinguished from the perception of a body in a non-artistic photography. While viewing different body representations in both artworks and photographs, subjects were required to evaluate the appeal of the portrayed persons. By using functional magnetic resonance imaging (fMRI) we show that the perception of a body within the context of art leads to a higher activation in the right parietal cortex and the extrastriate cortex bilaterally. Relating this result to concepts from previous research, we suggest that the perception of art is linked to visuo-spatial coding and also motor mapping. In contrast, the higher activity in the ventromedial prefrontal cortex and the primary visual cortex during the perception of a body in a non-artistic frame of reference, i.e. in a photograph, can be linked to processes of person evaluation. Possibly, the task to judge the appeal of a person in a photograph might be more daunting and, thus, cause emotional and even moral challenges being reflected in the ventromedial prefrontal activity. Taken together, perceptual experiences within an artistic vs. a non-artistic frame of reference are based on distinct patterns of neuronal activity.

    Individuals with body dysmorphic disorder (BDD) appear to possess abnormalities in the way they observe and discriminate visual information. A pre-occupation with perceived defects in appearance has been attributed to a local visual processing bias. We studied the nature of visual bias in individuals who may be at risk of developing BDD – those with high body image concerns (BICs) – by using inverted stimulus discrimination. Inversion disrupts global, configural information in favor of local, feature-based processing. 40 individuals with high BIC and 40 low BIC controls performed a discrimination task with upright and inverted faces, bodies, and scenes. Individuals with high BIC discriminated inverted faces and bodies faster than controls, and were also more accurate when discriminating inverted bodies and scenes. This reduction in inversion effect for high BIC individuals may be due to a stimulus-general local, detail-focused processing bias, which may be associated with maladaptive fixation on small features in their appearance.

    Body condition score (BCS) is considered an important tool for management of dairy cattle. The feasibility of estimating the BCS from digital images has been demonstrated in recent work. Regression machines have been successfully employed for automatic BCS estimation, taking into account information of the overall shape or information extracted on anatomical points of the shape. Despite the progress in this research area, such studies have not addressed the problem of modeling the shape of cows to build a robust descriptor for automatic BCS estimation. Moreover, a benchmark data set of images meant as a point of reference for quantitative evaluation and comparison of different automatic estimation methods for BCS is lacking. The main objective of this study was to develop a technique that was able to describe the body shape of cows in a reconstructive way. Images, used to build a benchmark data set for developing an automatic system for BCS, were taken using a camera placed above an exit gate from the milking robot. The camera was positioned at 3 m from the ground and in such a position to capture images of the rear, dorsal pelvic, and loin area of cows. The BCS of each cow was estimated on site by 2 technicians and associated to the cow images. The benchmark data set contained 286 images with associated BCS, anatomical points, and shapes. It was used for quantitative evaluation. A set of example cow body shapes was created. Linear and polynomial kernel principal component analysis was used to reconstruct shapes of cows using a linear combination of basic shapes constructed from the example database. In this manner, a cow's body shape was described by considering her variability from the average shape. The method produced a compact description of the shape to be used for automatic estimation of BCS. Model validation showed that the polynomial model proposed in this study performs better (error=0.31) than other state-of-the-art methods in estimating BCS even at the

    In this paper is presented a method to capture the motion of the human body from multi image video sequences without using markers. The process is composed of five steps: acquisition of video sequences, calibration of the system, surface measurement of the human body for each frame, 3-D surface tracking and tracking of key points. The image acquisition system is currently composed of three synchronized progressive scan CCD cameras and a frame grabber which acquires a sequence of triplet images. Self calibration methods are applied to gain exterior orientation of the cameras, the parameters of internal orientation and the parameters modeling the lens distortion. From the video sequences, two kinds of 3-D information are extracted: a three-dimensional surface measurement of the visible parts of the body for each triplet and 3-D trajectories of points on the body. The approach for surface measurement is based on multi-image matching, using the adaptive least squares method. A full automatic matching process determines a dense set of corresponding points in the triplets. The 3-D coordinates of the matched points are then computed by forward ray intersection using the orientation and calibration data of the cameras. The tracking process is also based on least squares matching techniques. Its basic idea is to track triplets of corresponding points in the three images through the sequence and compute their 3-D trajectories. The spatial correspondences between the three images at the same time and the temporal correspondences between subsequent frames are determined with a least squares matching algorithm. The results of the tracking process are the coordinates of a point in the three images through the sequence, thus the 3-D trajectory is determined by computing the 3-D coordinates of the point at each time step by forward ray intersection. Velocities and accelerations are also computed. The advantage of this tracking process is twofold: it can track natural points

    Adolescents' body image (BI) may not match their nutritional status. This study selected representative sample of healthy adolescents aged between 12 and 18 from public and private schools. Anthropometric measures were performed in order to calculate the body mass index (BMI) percentile. The silhouette scale proposed by Childress was used to evaluate BI, making it possible to assess BI satisfaction and BI distortion. The sample was composed of 1168 adolescents with a mean age of 14.7 years; 52.9% were female, 50.9% were fair-skinned, 62.4% had consumed or still consume alcohol and 67% attended public school. Male adolescents presented more overweight and obesity (28.4%) (p<0.05) than the female (17.1%). It was observed that 69.4% were dissatisfied with BI, 91.1% of the obese and 69.8% of those with overweight wished to lose body weight and 82.5% of those underweight wished to gain body weight. BI distortion was identified, since 35% of the adolescents who were underweight did not regard themselves thin, 39.1% of the overweight individuals and 62.1% of the obese did not see themselves in their adequate classifications. Adolescents with overweight/obesity were those who presented higher dissatisfaction with BI, mainly the females. Male individuals presented a greater wish of gaining weight. BI distortion was present in adolescents of all classes of BMI percentile.

    The role of possessing an abnormal body weight in the body image alterations of obese patients was evaluated in bariatric surgery subjects prior to and at long term after operation, when body weight and shape had become steadily normalized. Body image was assessed by the body dissatisfaction scale of the Eating Disorders Inventory, the Body Shape Questionnaire, and the Body Attitude Questionnaire. When the individuals were obese, a sharply impaired body image was observed; following operation, weight loss corresponded to normalization of body dissatisfaction, feeling of fatness, and physical attractiveness, whereas body disparagement and salience of shape, although improved in comparison to preoperative data, remained significantly different from that of controls. In the obese patients, some aspects of body image alterations are substantially accounted for by overweight status; other aspects reflect inner feelings, which are partially independent of the actual body weight and shape.

The patient presented with severe pain, sensory disturbance, and distorted body image at the site of initial injury and other body sites. Tactile localization training (TLT) at only the site of initial injury decreased severe pain at the site of initial injury and the secondary affected sites, whereas TLT at secondary affected sites had no effect. These results highlighted the importance of assessing changes in patients' pain processes to determine the part of the body where TLT should be applied.

    Maternal depression increases risk of adverse perinatal outcomes, and recent evidence suggests that body image may play an important role in depression. 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.

    Ovid's "De medicamine faciei feminae" contains the astonishing sentence "Culta placent - all that is artificial is beautiful". In his "Éloge du maquillage" Baudelaire, buidling on Ovid's argument, states that first culture as picture and construction of beauty brings forth the truth of Nature and claims that cosmetics that allow errors of beauty to disappear artificially produce the true fulfillment of human nature. The present article looks into the historical roots of the body images that have emerged in modern times and attempts to derive structural devices for an ethical assessment of the potential we have to enhance human nature.

    Body image can be influenced by day-to-day events, including food intake. The present study investigated the effects of foods typically perceived as "healthy" or "unhealthy" on state body image and mood. College-aged women were told the experiment was designed to assess the effects of food on cognition. Using a between-subjects design, participants consumed isocaloric amounts of foods perceived to be healthy (banana) or unhealthy (donut) or ate nothing. Next, participants completed three cognitive tasks. Prior to eating and following the cognitive tests, participants completed the BISS, POMS, the Figure Rating Scale, and the Restraint Scale. Body satisfaction decreased following intake of a donut, but was not altered in the other conditions. Depression scores significantly decreased after intake of either a donut or banana, but did not decrease in the no-food condition. Tension scores decreased significantly after consumption of a banana and in the no-food condition, but did not decrease following consumption of a donut. These results indicate that intake of a food that is perceived as unhealthy negatively affects state body image. PMID:21669241

    Physical, psychological and social changes that occur during adolescence can markedly affect dietary habits and nutritional health. Physical changes including rapid growth place extra nutritional requirements on adolescents, while culture and society require adjustments in all of the aspects of daily living, including psychosocial well-being. Adolescents become focused on the physical appearance and any deviation from the ideal figure can result in negative dieting behavior, social withdrawal, poor self-esteem and increased health vulnerability. The paper presents some of the results of an international comparative study on risk and protective factors of adolescent health and well being, related to BMI, dieting behavior and body image and their relationship to psychosocial well-being (somatic stress, anxiety, depression, life satisfaction and self-esteem). Within an ecological cultural framework, it looks at group-specific differences of Albanian and Bosnian adolescents within different socio-cultural contexts across six European countries: two EU members (Italy and Austria) and four communities in the state of socioeconomic and political transition (Croatia, Bosnia and Herzegovina, Albania and Kosovo). The survey collected data from 2000 adolescents between 15 and 18 years of age. The study demonstrated a strong relationship between BMI and body dissatisfaction, between body image and dietary habits, and strong effects of body image on all indicators of psychosocial health. In addition to expected marked gender differences in all countries, the obtained results indicate significant intracultural variations related to socioeconomic status as well as considerable intercultural variations due to variable influence specific social and cultural contexts.

    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.

    Static photographs are currently the most often employed stimuli in research on social perception. The method of photograph acquisition might affect the depicted subject's facial appearance and thus also the impression of such stimuli. An important factor influencing the resulting photograph is focal length, as different focal lengths produce various levels of image distortion. Here we tested whether different focal lengths (50, 85, 105 mm) affect depicted shape and perception of female and male faces. We collected three portrait photographs of 45 (22 females, 23 males) participants under standardized conditions and camera setting varying only in the focal length. Subsequently, the three photographs from each individual were shown on screen in a randomized order using a 3-alternative forced-choice paradigm. The images were judged for attractiveness, dominance, and femininity/masculinity by 369 raters (193 females, 176 males). Facial width-to-height ratio (fWHR) was measured from each photograph and overall facial shape was analysed employing geometric morphometric methods (GMM). Our results showed that photographs taken with 50 mm focal length were rated as significantly less feminine/masculine, attractive, and dominant compared to the images taken with longer focal lengths. Further, shorter focal lengths produced faces with smaller fWHR. Subsequent GMM revealed focal length significantly affected overall facial shape of the photographed subjects. Thus methodology of photograph acquisition, focal length in this case, can significantly affect results of studies using photographic stimuli perhaps due to different levels of perspective distortion that influence shapes and proportions of morphological traits.

    Schulz, Georg; Deyhle, Hans; Müller, Bert

    Computed tomography based on X-rays is known to provide the best spatial resolution of all clinical three-dimensional imaging facilities and currently reaches a fraction of a millimeter. Better spatial and density resolution is obtained by means of micro computed tomography well established in the field of materials science. It is also very supportive imaging human tissues down to the level of individual cells (Lareida et al. J. Microsc. 234:95, 2009). The article demonstrates the power of micro computed tomography for imaging parts of the human body such as teeth, inner ear, cerebellum, tumors, and urethral tissue with conventional X-ray sources and synchrotron radiation facilities in absorption and phase contrast modes. The second part of the chapter relies on scanning X-ray scattering of tooth slices (Müller et al. Eur. J. Clin. Nanomed. 3:30, 2010) to uncover the presence of nanostructures including their anisotropy and orientation. This imaging technique gives unrivalled insights for medical experts, which will have a major influence on fields such as dental and incontinence treatments.

  5. Rhythm is it: effects of dynamic body feedback on affect and attitudes

    2014-01-01

    Body feedback is the proprioceptive feedback that denominates the afferent information from position and movement of the body to the central nervous system. It is crucial in experiencing emotions, in forming attitudes and in regulating emotions and behavior. This paper investigates effects of dynamic body feedback on affect and attitudes, focusing on the impact of movement rhythms with smooth vs. sharp reversals as one basic category of movement qualities. It relates those qualities to already explored effects of approach vs. avoidance motor behavior as one basic category of movement shape. Studies 1 and 2 tested the effects of one of two basic movement qualities (smooth vs. sharp rhythms) on affect and cognition. The third study tested those movement qualities in combination with movement shape (approach vs. avoidance motor behavior) and the effects of those combinations on affect and attitudes toward initially valence-free stimuli. Results suggest that movement rhythms influence affect (studies 1 and 2), and attitudes (study 3), and moderate the impact of approach and avoidance motor behavior on attitudes (study 3). Extending static body feedback research with a dynamic account, findings indicate that movement qualities – next to movement shape – play an important role, when movement of the lived body is an independent variable.

    This study was designed to assess the association between stress, positive affect and catecholamine levels in meditation and control groups. The meditation group consisted of 67 subjects who regularly engaged in mind-body training of "Brain-Wave Vibration" and the control group consisted of 57 healthy subjects. Plasma catecholamine (norepinephrine (NE), epinephrine (E), and dopamine (DA)) levels were measured, and a modified form of the Stress Response Inventory (SRI-MF) and the Positive Affect and Negative Affect Scale (PANAS) were administered. The meditation group showed higher scores on positive affect (p=.019) and lower scores on stress (p<.001) compared with the control group. Plasma DA levels were also higher in the meditation (p=.031) than in the control group. The control group demonstrated a negative correlation between stress and positive affects (r=-.408, p=.002), whereas this correlation was not observed in the meditation group. The control group showed positive correlations between somatization and NE/E (r=.267, p=.045) and DA/E (r=.271, p=.042) ratios, whereas these correlations did not emerge in the meditation group. In conclusion, these results suggest that meditation as mind-body training is associated with lower stress, higher positive affect and higher plasma DA levels when comparing the meditation group with the control group. Thus, mind-body training may influence stress, positive affect and the sympathetic nervous system including DA activity.

    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

    Increasing attention is being given to evaluating and treating body image difficulties of patients undergoing cancer treatment. Head and neck cancer significantly alters physical appearance and bodily functioning and therefore directly impacts body image. Research involving body image in head and neck cancer patients is growing, and this review considers published findings from 2013 to 2014. Primary attention is given to discussing recent advancements in body image assessment, qualitative studies, descriptive research, and psychosocial intervention studies relevant to body image. Limitations and necessary advancements in this field are noted, and a commentary is provided on the state of the current literature. PMID:25416316

    This paper draws on literature, empirical data and a range of theoretical perspectives on the maternal body to examine understandings of the relationship between a pregnant woman and her foetus, with a particular focus on the body images used by women to represent this relationship. Psychoanalytic and nursing accounts of the relationship between mother and foetus have often described a symbiotic 'oneness' or unity during pregnancy. Such accounts, however, stress the temporary nature of this unity and identify a series of 'stages' of separation or 'polarisation' between mother and foetus during pregnancy. In contrast, many of the 25 women who participated in our interview study of new motherhood described a confusion of the boundary between self and foetus. For many women the experience of pregnancy and the relationship with the unborn baby was ambiguous and uncertain. Importantly, none of these women described her relationship with the foetus as a series of developmental stages, but rather saw it as fluctuating throughout pregnancy. These findings are more consistent with the work of feminist theorists who describe pregnancy as a dynamic and fluid merging of the inside and the outside of the body/self.

    The aim of this article was to study the effect of virtual-reality exposure to situations that are emotionally significant for patients with eating disorders (ED) on the stability of body-image distortion and body-image dissatisfaction. A total of 85 ED patients and 108 non-ED students were randomly exposed to four experimental virtual environments: a kitchen with low-calorie food, a kitchen with high-calorie food, a restaurant with low-calorie food, and a restaurant with high-calorie food. In the interval between the presentation of each situation, body-image distortion and body-image dissatisfaction were assessed. Several 2 x 2 x 2 repeated measures analyses of variance (high-calorie vs. low-calorie food x presence vs. absence of people x ED group vs. control group) showed that ED participants had significantly higher levels of body-image distortion and body dissatisfaction after eating high-calorie food than after eating low-calorie food, while control participants reported a similar body image in all situations. The results suggest that body-image distortion and body-image dissatisfaction show both trait and state features. On the one hand, ED patients show a general predisposition to overestimate their body size and to feel more dissatisfied with their body image than controls. On the other hand, these body-image disturbances fluctuate when participants are exposed to virtual situations that are emotionally relevant for them. PMID:20950176

    Here, we sought to replicate previous work showing a relationship between connectedness to nature and body appreciation, and extend it by examining associations between exposure to natural environments and other body image-related variables. An online sample of 399 U.S. women and men (Mage=34.55 years) completed measures of body appreciation, connectedness to nature, nature exposure, appearance investment, sociocultural attitudes towards appearance, and self-esteem. Path analysis showed that nature exposure and connectedness to nature, respectively, were associated with body appreciation in women and men, both directly and indirectly via self-esteem. Connectedness to nature also mediated the link between nature exposure and body appreciation. In men, but not women, the link between connectedness to nature and body appreciation was also mediated by appearance investment and internalisation of a muscular ideal. These results may point to novel methods for promoting more positive body image in adults through engagement with nature.

    Breakfast has psychological and nutritional benefits due to physiological mechanisms and expectations about health impact. Beliefs people hold about calories in food can adversely affect mood and body-image satisfaction and such adverse reactions can be predicted by body mass index. The objectives were to test the effect of consuming isocaloric breakfasts, appearing different in calorie content, on appetite, mood and body-image satisfaction, and to assess impact on daily nutrient intake. One-hundred-and-twenty-three women were randomly assigned to eat a cereal or muffin breakfast which "appeared" different in calorie content while unaware they were isocaloric. Participants estimated calories of breakfast, appetite, mood, and body-image satisfaction on a daily basis for seven-days. The cereal breakfast was perceived to be lower in calories, made participants fuller, happier, relaxed, and more satisfied about weight and body compared to the muffin breakfast. Differences in estimated daily fibre and micronutrient intake were compatible with the design. Breakfasts were isocaloric yet the cereal breakfast was rated lower in calories and produced more positive psychological reactions. This evidence indicates the power of perceptions of foods to influence important attributes of health and well-being which could be valuable in dietary interventions where mood and body image satisfaction affect outcome.

    This study aims to examine the associations between BMI, disordered eating attitude, body dissatisfaction in female adolescents, and descriptive attributes assigned to silhouettes of varying sizes in male and female adolescents, aged 11 to 15, in rural South Africa. Height and weight were measured to determine BMI. Age and sex-specific cut-offs for underweight and overweight/obesity were determined using the International Obesity Task Force cut-offs. Body image satisfaction using Feel-Ideal Discrepancy (FID) scores, Eating Attitudes Test-26 (EAT-26), and perceptual female silhouettes were collected through self-administered questionnaires in 385 adolescents from the Agincourt Health and Socio-Demographic Surveillance System (HSDSS). Participants self-reported their Tanner pubertal stage and were classified as early pubertal (< = Tanner stage 2), and mid to post pubertal (Tanner stage > 2). Mid to post pubertal boys and girls were significantly heavier, taller, and had higher BMI values than their early pubertal counterparts (all p<0.001). The prevalence of overweight and obesity was higher in the girls than the boys in both pubertal stages. The majority (83.5%) of the girls demonstrated body dissatisfaction (a desire to be thinner or fatter). The girls who wanted to be fatter had a significantly higher BMI than the girls who wanted to be thinner (p<0.001). There were no differences in EAT-26 scores between pubertal groups, within the same sex, and between boys and girls within the two pubertal groups. The majority of the boys and the girls in both pubertal groups perceived the underweight silhouettes to be "unhappy" and "weak" and the majority of girls in both pubertal groups perceived the normal silhouettes to be the "best". These findings suggest a need for policy intervention that will address a healthy body size among South African adolescents. PMID:27171420

    Large male body size is typically favored by directional sexual selection through competition for mates. However, alternative male life-history phenotypes, such as "sneakers," should decrease the strength of sexual selection acting on body size of large "fighter" males. We tested this prediction with salmon species; in southern populations, where sneakers are common, fighter males should be smaller than in northern populations, where sneakers are rare, leading to geographical clines in sexual size dimorphism (SSD). Consistent with our prediction, fighter male body size and SSD (fighter male∶female size) increase with latitude in species with sneaker males (Atlantic salmon Salmo salar and masu salmon Oncorhynchus masou) but not in species without sneakers (chum salmon Oncorhynchus keta and pink salmon Oncorhynchus gorbuscha). This is the first evidence that sneaker males affect SSD across populations and species, and it suggests that alternative male mating strategies may shape the evolution of body size. PMID:27420790

  4. RF Device for Acquiring Images of the Human Body

    NASA Technical Reports Server (NTRS)

    Gaier, Todd C.; McGrath, William R.

    2010-01-01

    A safe, non-invasive method for forming images through clothing of large groups of people, in order to search for concealed weapons either made of metal or not, has been developed. A millimeter wavelength scanner designed in a unique, ring-shaped configuration can obtain a full 360 image of the body with a resolution of less than a millimeter in only a few seconds. Millimeter waves readily penetrate normal clothing, but are highly reflected by the human body and concealed objects. Millimeter wave signals are nonionizing and are harmless to human tissues when used at low power levels. The imager (see figure) consists of a thin base that supports a small-diameter vertical post about 7 ft (=2.13 m) tall. Attached to the post is a square-shaped ring 2 in. (=5 cm) wide and 3 ft (=91 cm) on a side. The ring is oriented horizontally, and is supported halfway along one side by a connection to a linear bearing on the vertical post. A planar RF circuit board is mounted to the inside of each side of the ring. Each circuit board contains an array of 30 receivers, one transmitter, and digitization electronics. Each array element has a printed-circuit patch antenna coupled to a pair of mixers by a 90 coupler. The mixers receive a reference local oscillator signal to a subharmonic of the transmitter frequency. A single local oscillator line feeds all 30 receivers on the board. The resulting MHz IF signals are amplified and carried to the edge of the board where they are demodulated and digitized. The transmitted signal is derived from the local oscillator at a frequency offset determined by a crystal oscillator. One antenna centrally located on each side of the square ring provides the source illumination power. The total transmitted power is less than 100 mW, resulting in an exposure level that is completely safe to humans. The output signals from all four circuit boards are fed via serial connection to a data processing computer. The computer processes the approximately 1-MB

    Sexual behavior is associated with body image, but the directionality of this association is unclear. This study used longitudinal data from a sample of previously abstinent college students (N = 100, 45% female, 49% European American, 26% Latino American, 25% African American) to test whether satisfaction with appearance changed after first intercourse. Male students were more satisfied with their appearance after first intercourse, whereas female students became slightly less satisfied with their appearance. These findings demonstrate that first intercourse can lead to changes in well-being, even if the transition takes places in late adolescence. In addition, they suggest that gendered cultural expectations regarding sexual behavior are associated with differing psychological outcomes for male and female adolescents. PMID:20488512

    A growing body of literature has highlighted the increased prevalence of body image concerns and associations with health outcomes among gay and bisexual men (GBM). Little research, however, has examined the link between body image and social oppression for ethnoracialized GBM. Using an intersectionality lens and qualitative inductive analysis, data were collected through focus groups and interviews with GBM (n=61) who identify with one of four ethnoracial groups (Black, East/Southeast Asian, South Asian, Latino/Brazilian). Three main themes emerged: (1) body image idealization in gay/bisexual male culture, (2) negotiating a racialized body image, and (3) negotiating the impact of body image on relationship with self and others. The study results highlighted how multiple forms of oppression (e.g., racism, sexism) intersected with one another to impact the body image and overall well-being among ethnoracialized GBM.

    2012-01-01

    Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores). Large-bodied reef fishes also tend to be at greatest risk of overfishing, and their loss can result in a myriad of either cascading (direct) or indirect trophic and other effects. While many studies have investigated habitat characteristics affecting populations of small-bodied reef fishes, few have explored the relationship between large-bodied species and their environment. Here, we describe the distribution of the large-bodied reef fishes in the Mariana Archipelago with an emphasis on the environmental factors associated with their distribution. Of the factors considered in this study, a negative association with human population density showed the highest relative influence on the distribution of large-bodied reef fishes; however, depth, water temperature, and distance to deep water also were important. These findings provide new information on the ecology of large-bodied reef fishes can inform discussions concerning essential fish habitat and ecosystem-based management for these species and highlight important knowledge gaps worthy of additional research.

    Compared with men who have sex with women, some evidence suggests that men who have sex with men (MSM) have increased prevalence of body image dissatisfaction. MSM also have a higher prevalence of sexually transmissible infections (STIs) than other population groups. As part of a cross-sectional study, body image among 104 MSM using the standardised, validated Male Body Attitudes Scale was assessed. Associations between body image and prevalent STI were examined. Body image was not associated with prevalent STI in unadjusted [prevalence ratio (PR): 1.14, 95% confidence interval (CI): 0.86-1.52] or adjusted analyses (PR: 1.17, 95% CI: 0.89-1.53).

    Background: Substance dependency is one of the biggest problems and worries of the world. It stunts the growth of society and causes various problems such as reduction in public health, increase in mortality, rise in social and domestic traumas, loss of educational and occupational opportunities, involvement with the judicial system, and development of the substance-abuse cycle. Objectives: The aim of this study was to determine the role of metacognition and body image in predicting alexithymia in substance abusers. Patients and Methods: The research sample included addicts (males and females aged 10 to 70 years) who referred to the addiction treatment and counseling centers of three Iranian cities of Zahedan, Sari, and Neyriz. Participants were selected by random sampling. The metacognitive strategy questionnaire (MCQ-30), physical self-description questionnaire (PSDQ), and Toronto alexithymia scale (TAS-20) were used for data collection. The hypotheses were tested using the Pearson’s correlation method and regression analysis. Results: According to the results of the current study, the highest correlation was between alexithymia and the cognitive awareness subscale (r = 0.305; P < 0.01).There was no significant correlation between alexithymia and body image. Based on the multiple regression analysis, the three predictors explained 11% of the variance (R2 = 0. 11, F = 3.981; P < 0.01). Cognitive awareness significantly predicted 9% of the variance (β = 0.305; P < 0.01), and the other subscales predicted about 2%. Conclusions: These findings demonstrated that metacognition had an important role in predicting alexithymia in the substance abusers, which underscores the necessity of precautionary measures.

    Dance has been found to both enhance and undermine body image. Most of the literature has focused on ballet dancers and has neglected the role of identity as a dancer. This study assessed general and dance specific body image and dancer identity in 77 female modern dancers. Compared to samples of non-clinical college women, this sample had higher body appreciation and lower drive for thinness and self-objectification. White dancers in the sample also had positive levels of dancer body efficacy/acceptance whereas as non-White dancers had negative levels of this variable. Identity as a dancer was negatively correlated with body appreciation and dancer body perceptions and not related to the number of years of dance experience. Of general and dance specific body image, body appreciation emerged as the unique predictor. The findings warrant further research on positive body image, modern dancers, and identity. PMID:20650693

  19. Effect of sway on image fidelity in whole-body digitizing

    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.

    Objectives: Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Methods: Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

    The goal of this study was to examine the ways in which transgender youth experience their bodies with regard to gender and body size. Ninety transgender youth and young adults completed in-depth interviews in eight metropolitan areas of the United States, Canada, and Ireland. Using a queer perspective, qualitative analyses revealed two broad conceptual categories: body dissatisfaction and body satisfaction. Within these categories, participants focused on body issues related to gender characteristics and body size. Findings revealed evidence of self-criticism and social distress related to body image dissatisfaction and self-acceptance and social acceptance related to body image satisfaction. Data demonstrated how gender, body size, and the intersection of gender and body size influenced personal perceptions of body dissatisfaction and satisfaction. Developmental processes were evident: participants further along in consolidating a gender identity described gaining a sense of social awareness, self-acceptance, and body satisfaction reflecting a sense of resilience.

    The high soft-tissue contrast of MRI and the absence of ionizing radiation make it a valuable tool for assessment of body pathology in children. Infants and young children are often unable to cooperate with awake MRI so sedation or general anesthesia might be required. However, given recent data on the costs and potential risks of anesthesia in young children, there is a need to try to decrease or avoid sedation in this population when possible. Child life specialists in radiology frequently use behavioral techniques and audiovisual support devices, and they practice with children and families using mock scanners to improve child compliance with MRI. Optimization of the MR scanner environment is also important to create a child-friendly space. If the child can remain inside the MRI scanner, a variety of emerging techniques can reduce the effect of involuntary motion. Using sequences with short acquisition times such as single-shot fast spin echo and volumetric gradient echo can decrease artifacts and improve image quality. Breath-holding, respiratory triggering and signal averaging all reduce respiratory motion. Emerging techniques such as radial and multislice k-space acquisition, navigator motion correction, as well as parallel imaging and compressed sensing reconstruction methods can further accelerate acquisition and decrease motion. Collaboration among radiologists, anesthesiologists, technologists, child life specialists and families is crucial for successful performance of MRI in young children. PMID:27229508

    Deficits in dopamine D2/D3 receptor (D2R/D3R) binding availability using PET imaging have been reported in obese humans and rodents. Similar deficits have been reported in cocaine-addicts and cocaine-exposed primates. We found that D2R/D3R binding availability negatively correlated with measures of body weight at the time of scan (ventral striatum), at 1 (ventral striatum) and 2 months (dorsal and ventral striatum) post scan in rats. Cocaine preference was negatively correlated with D2R/D3R binding availability 2 months (ventral striatum) post scan. Our findings suggest that inherent deficits in striatal D2R/D3R signaling are related to obesity and drug addiction susceptibility and that ventral and dorsal striatum serve dissociable roles in maintaining weight gain and cocaine preference. Measuring D2R/D3R binding availability provides a way for assessing susceptibility to weight gain and cocaine abuse in rodents and given the translational nature of PET imaging, potentially primates and humans.

    Attending to the material discursive constructions of the patient body within cone beam computed tomography (CBCT) imaging in radiotherapy treatments, in this paper I describe how bodies and machines co-create images. Using an analytical framework inspired by Science and Technology Studies and Feminist Technoscience, I describe the interplay between machines and bodies and the implications of materialities and agency. I argue that patients' bodies play a part in producing scans within acceptable limits of machines as set out through organisational arrangements. In doing so I argue that bodies are fabricated into the order of work prescribed and embedded within and around the CBCT system, becoming, not only the subject of resulting images, but part of that image. The scan is not therefore a representation of a passive subject (a body) but co-produced by the work of practitioners and patients who actively control (and contort) and discipline their body according to protocols and instructions and the CBCT system. In this way I suggest they are 'con-forming' the CBCT image. A Virtual Abstract of this paper can be found at: https://youtu.be/qysCcBGuNSM. PMID:26596682

    This paper reports on the perception of changing body image and well-being for patients who had undergone plastic surgery following massive weight loss. The exploratory, qualitative study was undertaken with 20 patients from one teaching hospital in the south of England. Semi-structured interviews were carried out and a thematic analysis of the data undertaken. The results provide important insights regarding body contouring influencing body image change and the adjustment process involved. The ability to pursue self-esteem and the accruing social benefits is emphasized in the interrelated sub themes including social acceptance, undoing depression and sexual vitality. Body contouring surgery following massive weight loss appears to facilitate improvement in body image and well-being. Adjustment to the changing body image is both empowering and challenging. Supportive educational programmes need to be developed to assist this transition to a more positive body image and appreciation; these could usefully include access to and involvement with patient support groups.

    Body dissatisfaction and attempts to lose weight are increasingly common among adolescents. Research has identified a number of factors significantly associated with body image, including sex, media, parental relationship, and puberty as well as weight and popularity. It was hypothesized that popular adolescents would have greater body dissatisfaction, more body distortion, and lower body esteem. From a rural high school 116 10th and 12th grade students were surveyed. Two teachers from the school also completed a Body Image Figure scale for each student. Subjects rated each grade member on a 5-point Likert-type scale, indicating how much they liked the classmate. A Social Preference rating (Popularity) was calculated for each subject from these ratings. Each subject also completed a Body Image Figure scale and Body Esteem scale. Body distortion was calculated by comparing the teachers' and a student's responses. Significant sex differences were found for scores on body satisfaction, distortion, and esteem, but none for popularity with distortion and body esteem. A relationship between popularity and body satisfaction was found, with the most popular adolescents reporting the least discrepancy between their ideal body image and their current body image. Popular adolescents are most satisfied with their body type.

    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

  12. Factors Affecting Image Quality in Near-field Ultra-wideband Radar Imaging for Biomedical Applications

    NASA Astrophysics Data System (ADS)

    Curtis, Charlotte

    Near-field ultra-wideband radar imaging has potential as a new breast imaging modality. While a number of reconstruction algorithms have been published with the goal of reducing undesired responses or clutter, an in-depth analysis of the dominant sources of clutter has not been conducted. In this thesis, time domain radar image reconstruction is demonstrated to be equivalent to frequency domain synthetic aperture radar. This reveals several assumptions inherent to the reconstruction algorithm related to radial spreading, point source antennas, and the independent summation of point scatterers. Each of these assumptions is examined in turn to determine which has the greatest impact on the resulting image quality and interpretation. In addition, issues related to heterogeneous and dispersive media are addressed. Variations in imaging parameters are tested by observing their influence on the system point spread function. Results are then confirmed by testing on simple and detailed simulation models, followed by data acquired from human volunteers. Recommended parameters are combined into a new imaging operator that is demonstrated to generate results comparable to a more accurate signal model, but with a 50 fold improvement in computational efficiency. Finally, the most significant factor affecting image quality is determined to be the estimate of tissue properties used to form the image.

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.

    Fat mass is the most variable component in the human body, both when comparing several individuals and when considering changes in the same person throughout life. Obesity is characterized by an excess of body fat that affects health and well-being of individuals. Risk associated with excess body fat is due, in part, to location of fat rather than to total amount. Today is stated that causes and metabolic consequences of regional distribution of fat are of particular clinical importance. To identify a compartment of morbid adipose tissue and to be able to act on it is one of the main aims of the present research. In this review, we have revised the existing literature on location and characteristics of total body fat in human adult. We have focused on abdominal region, basing this review on the use of modern imaging techniques available nowadays, such as computerized tomography and magnetic resonance imaging, with their advantages and limitations. The purpose of this review is to assess whether it is possible to know the body composition and fat distribution on the basis of image methods. Computed tomography technique was first applied in studies of obesity, but today, due to the inconvenience of irradiating the patient, this technique is being replaced by magnetic resonance that, in addition to avoid radiation, provides images of extraordinary quality. Both methods allow to subdivide the classic general fat depots in others more specific. Subcutaneous fat depot can be superficial or deep, while visceral can be divided in mesenteric, omental or epiploic, retroperitoneal and perirrenal fat. In addition, these modern techniques of imaging permit to study muscular fat, considered by some authors as the new fat compartment. Muscular fat includes fat located between skeletal muscle fibers, called extramyocellular fat, as well as lipids located within skeletal muscle fibers (intramyocellular fat). Its importance lies not only in size, similar to visceral fat, but on its

    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.

    The aim of this study was to examine the effects of a QTL in different genetic backgrounds. A QTL affecting body mass on chromosome 6 was identified in an F2 cross between two lines of mice that have been divergently selected for this trait. The effect of the QTL on mass increased between 6 and 10 weeks of age and was not sex-specific. Body composition analysis showed effects on fat-free dry body mass and fat mass. To examine the effect of this QTL in different genetic backgrounds, the high body mass sixth chromosome was introgressed into the low body mass genetic background and vice versa by repeated marker-assisted backcrossing. After three generations of backcrossing, new F2 populations were established within each of the introgression lines by crossing individuals that were heterozygous across the sixth chromosome. The estimated additive effect of the QTL on 10-week body mass was similar in both genetic backgrounds and in the original F2 population (i.e., ~0.4 phenotypic standard deviations); no evidence of epistatic interaction with the genetic background was found. The 95% confidence interval for the location of the QTL was refined to a region of approximately 7 cM between D6Mit268 and D6Mit123. PMID:15339634

    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. PMID:26176993

    Compression ratio (CR) has been the de facto standard index of compression level for medical images. The aim of the study is to evaluate the CR, peak signal-to-noise ratio (PSNR), and a perceptual quality metric (high-dynamic range visual difference predictor HDR-VDP) as objective indices of image fidelity for Joint Photographic Experts Group (JPEG) 2000 compressed body computed tomography (CT) images, from the viewpoint of visually lossless compression approach. A total of 250 body CT images obtained with five different scan protocols (5-mm-thick abdomen, 0.67-mm-thick abdomen, 5-mm-thick lung, 0.67-mm-thick lung, and 5-mm-thick low-dose lung) were compressed to one of five CRs (reversible, 6:1, 8:1, 10:1, and 15:1). The PSNR and HDR-VDP values were calculated for the 250 pairs of the original and compressed images. By alternately displaying an original and its compressed image on the same monitor, five radiologists independently determined if the pair was distinguishable or indistinguishable. The kappa statistic for the interobserver agreement among the five radiologists' responses was 0.70. According to the radiologists' responses, the number of distinguishable image pairs tended to significantly differ among the five scan protocols at 6:1-10:1 compressions (Fisher-Freeman-Halton exact tests). Spearman's correlation coefficients between each of the CR, PSNR, and HDR-VDP and the number of radiologists who responded as distinguishable were 0.72, -0.77, and 0.85, respectively. Using the radiologists' pooled responses as the reference standards, the areas under the receiver-operating-characteristic curves for the CR, PSNR, and HDR-VDP were 0.87, 0.93, and 0.97, respectively, showing significant differences between the CR and PSNR (p=0.04), or HDR-VDP (p<0.001), and between the PSNR and HDR-VDP (p<0.001). In conclusion, the CR is less suitable than the PSNR or HDR-VDP as an objective index of image fidelity for JPEG2000 compressed body CT images. The HDR-VDP is more

  1. Whole-Body MRI in Children: Current Imaging Techniques and Clinical Applications

    PubMed Central

    2015-01-01

    Whole-body magnetic resonance imaging (MRI) is increasingly used in children to evaluate the extent and distribution of various neoplastic and non-neoplastic diseases. Not using ionizing radiation is a major advantage of pediatric whole-body MRI. Coronal and sagittal short tau inversion recovery imaging is most commonly used as the fundamental whole-body MRI protocol. Diffusion-weighted imaging and Dixon-based imaging, which has been recently incorporated into whole-body MRI, are promising pulse sequences, particularly for pediatric oncology. Other pulse sequences may be added to increase diagnostic capability of whole-body MRI. Of importance, the overall whole-body MRI examination time should be less than 30-60 minutes in children, regardless of the imaging protocol. Established and potentially useful clinical applications of pediatric whole-body MRI are described. PMID:26355493

  2. Does short-term fasting promote changes in state body image?

    Fasting, or going a significant amount of time without food, is a predictor of eating pathology in at-risk samples. The current study examined whether acute changes in body image occur after an episode of fasting in college students. Furthermore, it evaluated whether individual difference variables might inform the relationship between fasting and shifts in body image. Participants (N=186) included male (44.7%) and female college students who completed the Body Image States Scale (BISS) and other eating-related measures before a 24-h fast. Participants completed the BISS again after fasting. While no overall changes in BISS scores emerged during the study, some individuals evidenced body image improvement. Baseline levels of disinhibition and self-reported fasting at least once per week uniquely predicted improvement in body image. Individual difference variables may play a role in how fasting could be reinforced by shifts in body image.

    AAS users and contemplators were investigated for differences in aggression and body image concern. Prevalence rates were sought as a secondary aim. 396 male adolescents at Norwegian high schools completed a questionnaire battery during school hours. Prevalence of AAS use showed 4.0%; AAS contemplation showed 5.1%. No significant differences between the AAS users and contemplators were found on levels of aggression and body image concern. AAS users and contemplators reported significantly higher levels of aggression and body image concern compared nonusing controls. AAS contemplators enhance understanding of AAS use by representing psychosocial factors contributing to increased aggression, and AAS use or risk thereof indicative of an aggressive personality profile. Body image concerns for AAS users and contemplators may indicate that AAS use does not diminish body image concern, and that body image concern is a risk factor for AAS use. This is supportive of previous research.

    We examined the potential moderating effects of appearance investment, body image disturbance, and situational body image dysphoria on the drive for muscularity attitude-behaviour relationship. Participants (339 British college men, M(AGE)=20.00 years, SD=2.59) completed drive for muscularity attitude and behaviour, appearance investment, body image disturbance, and situational body image dysphoria measures. Results indicated higher levels of appearance investment, body image disturbance, and situational body image dysphoria were associated with increases in the drive for muscularity attitude's relationship with physique-enhancing behavioural engagement. Results help extend recent research that has moved beyond identifying correlates to examining ways that groups of variables interact to predict drive for muscularity behavioural engagement and may contribute to theory development.

    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. PMID:24008185

    Individuals with schizophrenia, particularly those with passivity symptoms, may not feel in control of their actions, believing them to be controlled by external agents. Cognitive operations that contribute to these symptoms may include abnormal processing in agency as well as body representations that deal with body schema and body image. However, these operations in schizophrenia are not fully understood, and the questions of general versus specific deficits in individuals with different symptom profiles remain unanswered. Using the projected-hand illusion (a digital video version of the rubber-hand illusion) with synchronous and asynchronous stroking (500 ms delay), and a hand laterality judgment task, we assessed sense of agency, body image, and body schema in 53 people with clinically stable schizophrenia (with a current, past, and no history of passivity symptoms) and 48 healthy controls. The results revealed a stable trait in schizophrenia with no difference between clinical subgroups (sense of agency) and some quantitative (specific) differences depending on the passivity symptom profile (body image and body schema). Specifically, a reduced sense of self-agency was a common feature of all clinical subgroups. However, subgroup comparisons showed that individuals with passivity symptoms (both current and past) had significantly greater deficits on tasks assessing body image and body schema, relative to the other groups. In addition, patients with current passivity symptoms failed to demonstrate the normal reduction in body illusion typically seen with a 500 ms delay in visual feedback (asynchronous condition), suggesting internal timing problems. Altogether, the results underscore self-abnormalities in schizophrenia, provide evidence for both trait abnormalities and state changes specific to passivity symptoms, and point to a role for internal timing deficits as a mechanistic explanation for external cues becoming a possible source of self-body input

    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.

    Events during the non-breeding season may affect the body condition of migratory birds and influence performance during the following breeding season. Migratory birds nesting in the Arctic often rely on endogenous nutrients for reproductive efforts, and are thus potentially subject to such carry-over effects. We tested whether king eider (Somateria spectabilis) arrival time and body mass upon arrival at breeding grounds in northern Alaska were affected by their choice of a winter region in the Bering Sea. We captured birds shortly after arrival on breeding grounds in early June 2002–2006 at two sites in northern Alaska and determined the region in which individuals wintered using satellite telemetry or stable isotope ratios of head feathers. We used generalized linear models to assess whether winter region explained variation in arrival body mass among individuals by accounting for sex, site, annual variation, and the date a bird was captured. We found no support for our hypothesis that either arrival time or arrival body mass of king eiders differed among winter regions. We conclude that wintering in different regions in the Bering Sea is unlikely to have reproductive consequences for king eiders in our study areas.

    The construct of imageability refers to the extent to which a word evokes a tangible sensation. Previous research (Westbury et al., 2013) suggests that the behavioral effects attributed to a word's imageability can be largely or wholly explained by two objective constructs, contextual density and estimated affect. Here, we extend these previous findings in two ways. First, we show that closely matched stimuli on the three measures of contextual density, estimated affect, and human-judged imageability show a three-way interaction in explaining variance in LD RTs, but that imagebility accounts for no additional variance after contextual density and estimated affect are entered first. Secondly, we demonstrate that the loci and functional connectivity (via graphical models) of the brain regions implicated in processing the three variables during that task are largely over-lapping and similar. These two lines of evidence support the conclusion that the effect usually attributed to human-judged imageability is largely or entirely due to the effects of other correlated measures that are directly computable.

    Body composition testing has been advocated as part of fitness test batteries in an educational effort to promote health-related fitness, and to prevent public health problems like obesity. However, the measurement of the body composition of children and youth, especially involving the use of skinfold calipers, has raised concerns. In two experiments the cognitive and affective consequences of skinfold caliper use in a 7th grade (155 boys, 177 girls, total N = 332) health/physical education context were examined. Experiment 1 demonstrated that the students could be taught to accurately measure a partner and/or significantly learn body fatness-related concepts compared to controls. It was also shown that inexpensive plastic Fat Control calipers produced accurate measurements. Experiment 2 was designed to replicate the significant cognitive outcome effects, and also to test the hypothesis that psychological damage is a likely consequence of skinfold caliper use-and that hypothesis was refuted. Specifically, knowledge scores, and outcome scores on adapted affect scales (e.g., PANAS, MAACL), physical self-esteem scales (CY-PSPP) and on the Social Physique Anxiety Scale supported the premise that skinfold calipers can be used in an educational context to facilitate cognitive learning without causing adverse affective consequences.

    2013-01-01

    Objectives In 1950, Kurt Schneider proposed that a considerable number of schizophrenia patients develop first-rank symptoms (FRS). In such cases, patients report made experiences, replaced control of will, thought insertion, broadcast or withdrawal and delusional perception, respectively. Although a number of recent studies tend to explain FRS in terms of neurobiological and neuropsychological processes, the origin of these symptoms still remains unknown. In this paper, we explore the subjective experience of patients with the following two FRS: (1) "made" impulses and (2) “made" volitional acts. Method The method applied for the study of two FRS consists first in the overview of psychiatric and philosophical literature and second in the further investigation of subjective experience in patients with FRS. Psychopathological and phenomenological aspects of FRS are discussed by means of patient cases. Results We discovered a profound transformation of intentionality and agency in schizophrenia patients with body-affecting FRS. This concept offers an insight into the interrelatedness between particular FRS. Conclusion We propose that the subjective experience of schizophrenia patients with body-affecting FRS is rooted in the disturbance of intentionality and diminished sense of agency. This theoretical account of body-affecting FRS will open up new directions in both phenomenological and neurobiological psychiatric research. PMID:24019932

    The present study examined associations between the Big Five personality domains and measures of men's body image. A total of 509 men from the community in London, UK, completed measures of drive for muscularity, body appreciation, the Big Five domains, and subjective social status, and provided their demographic details. The results of a hierarchical regression showed that, once the effects of participant body mass index (BMI) and subjective social status had been accounted for, men's drive for muscularity was significantly predicted by Neuroticism (β=.29). In addition, taking into account the effects of BMI and subjective social status, men's body appreciation was significantly predicted by Neuroticism (β=-.35) and Extraversion (β=.12). These findings highlight potential avenues for the development of intervention approaches based on the relationship between the Big Five personality traits and body image.

    2010-08-01

    This study examined how sociocultural messages differ for overweight and normal weight adolescents and how these messages predict body image and body change strategies. In total, 590 adolescents participated in the study. Overweight adolescents experienced greater body dissatisfaction, engaged in more strategies to lose weight, and experienced greater sociocultural messages to lose weight. Body dissatisfaction and sociocultural pressures predicted weight loss among overweight boys. Body image importance, and sociocultural pressures predicted increasing muscle bulk for normal and overweight boys. Weight loss for overweight girls was predicted by sociocultural pressures. Sociocultural pressures also predicted muscle increase for overweight and normal weight girls. Implications for intervention and prevention programs for overweight adolescent boys and girls are discussed.

    Exposure to media images of thin-and-beautiful women negatively affects the body image and mood states of young women. However, not all women are equally susceptible to these effects. The present experimental investigation with 123 young college women evaluated the moderating effects of the extent of internalization of media ideals. It also examined the preventative impact of two brief interventions (i.e., media literacy information with and without a dissonance-induction procedure). Results indicated that relative to a control group, the exposure to thin-and-beautiful media images adversely influenced the state body image of participants with high internalization levels. Media-literacy psychoeducation prior to the media exposure prevented this adverse effect. Adding a pre-exposure dissonance-induction procedure did not significantly enhance the preventative effects relative to psychoeducation alone. These results and their implications for the treatment and prevention of body image disturbances are discussed in the context of the empirical literature on the media's effects on body image.

    The localization of treatment targets is of utmost importance for patients receiving stereotactic body radiation therapy (SBRT), where the dose per fraction is large. While both setup or respiration-induced motion components affect the localization of the treatment volume, the purpose of this work is to describe our management of the intrafraction localization uncertainty induced by normal respiration. At our institution, we have implemented gated computed tomography (CT) acquisition with an active breathing control system (ABC), and 4-dimensional (4D) CT using a skin-based marker and retrospective respiration phase-based image sorting. During gated simulation, 3D CT images were acquired corresponding to end-inhalation and end-exhalation. For 4D CT imaging, 3D CT images were acquired corresponding to 8 phases of the respiratory cycle. In addition to gated or 4D CT images, we acquired a conventional free-breathing CT (FB). For both gated and 4D CT images, the target contours were registered to the FB scan in the planning system. These contours were then combined in the FB image set to form the internal target volume (ITV). Dynamic conformal arc treatment plans were generated for the ITV using the FB scan and the gated or 4D scans with an additional 7-mm margin for patient setup uncertainty. We have described our results for a pancreas and a lung tumor case. Plans were normalized so that the PTV received 95% of the prescription dose. The dose distribution for all the critical structures in the pancreas and lung tumor cases resulted in increased sparing when the ITV was defined using gated or 4D CT images than when the FB scan was used. Our results show that patient-specific target definition using gated or 4D CT scans lead to improved normal tissue sparing.

    Positive body image is defined as healthy body-related attitudes that go beyond the absence of distressful symptoms. A warm and secure relationship with an important other person has been linked with attitudes of acceptance and appreciation toward one's body as well as adaptive eating patterns. This study tested whether a warm and secure relationship with God was similarly related to positive body image. Undergraduate women completed self-report measures of religiosity, life satisfaction, body appreciation, body acceptance by others, functional orientation, and intuitive eating. Multiple regression analyses showed that relationship with God contributed variance to most of the well-being variables.

Participants were 193 yoga practitioners (124 Iyengar, 69 Bikram) and 127 university students (non-yoga participants) from Adelaide, South Australia. Participants completed questionnaire measures of positive body image, embodiment, self-objectification, and desire for thinness. Results showed yoga practitioners scored higher on positive body image and embodiment, and lower on self-objectification than non-yoga participants. In support of the embodiment model, the relationship between yoga participation and positive body image was serially mediated by embodiment and reduced self-objectification. Although Bikram practitioners endorsed appearance-related reasons for participating in yoga more than Iyengar practitioners, there were no significant differences between Iyengar and Bikram yoga practitioners on body image variables. It was concluded that yoga is an embodying activity that can provide women with the opportunity to cultivate a favourable relationship with their body.

    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.

    This experiment compared the effects of aerobic-training (AT) versus strength-training (ST) on body image among young women with pre-existing body image concerns. Theory-based correlates of body image change were also examined. Participants were 46 women (M age=21.5 years), randomly assigned to an 8-week AT or ST intervention consisting of supervised exercise 3 days/week. Multidimensional measures of body image were administered pre- and post-intervention, along with measures of physical fitness, perceived fitness, and exercise self-efficacy. Women in the AT condition reported greater reductions in social physique anxiety (p=.001) and tended to report greater improvements in appearance evaluation (p=.06) than women in the ST condition. Changes in perceived fatness, perceived aerobic endurance and aerobic self-efficacy were significantly correlated with body image change (ps<.003). Results provide direction for prescribing exercise to improve body image and advancing theory to account for the effects of exercise. PMID:24958656

    Study Objectives: Excessive daytime sleepiness commonly affects obese people, even in those without sleep apnea, yet its causes remain uncertain. We sought to determine whether acute dietary changes could induce or rescue wake impairments independent of body weight. Design: We implemented a novel feeding paradigm that generates two groups of mice with equal body weight but opposing energetic balance. Two subsets of mice consuming either regular chow (RC) or high-fat diet (HFD) for 8 w were switched to the opposite diet for 1 w. Sleep recordings were conducted at Week 0 (baseline), Week 8 (pre-diet switch), and Week 9 (post-diet switch) for all groups. Sleep homeostasis was measured at Week 8 and Week 9. Participants: Young adult, male C57BL/6J mice. Measurements and Results: Differences in total wake, nonrapid eye movement (NREM), and rapid eye movement (REM) time were quantified, in addition to changes in bout fragmentation/consolidation. At Week 9, the two diet switch groups had similar body weight. However, animals switched to HFD (and thus gaining weight) had decreased wake time, increased NREM sleep time, and worsened sleep/wake fragmentation compared to mice switched to RC (which were in weight loss). These effects were driven by significant sleep/wake changes induced by acute dietary manipulations (Week 8 → Week 9). Sleep homeostasis, as measured by delta power increase following sleep deprivation, was unaffected by our feeding paradigm. Conclusions: Acute dietary manipulations are sufficient to alter sleep and wakefulness independent of body weight and without effects on sleep homeostasis. Citation: Perron IJ, Pack AI, Veasey S.

    2014-07-01

    To facilitate accessing and downloading spatially resolved imagery of asteroids and comets in the NASA Planetary Data System (PDS), we have created the Small Bodies Image Browser. It is a HTML5 webpage that runs inside a standard web browser needing no installation (http://sbn.psi.edu/sbib/). The volume of data returned by spacecraft missions has grown substantially over the last decade. While this wealth of data provides scientists with ample support for research, it has greatly increased the difficulty of managing, accessing and processing these data. Further, the complexity necessary for a long-term archive results in an architecture that is efficient for computers, but not user friendly. The Small Bodies Image Browser (SBIB) is tied into the PDS archive of the Small Bodies Asteroid Subnode hosted at the Planetary Science Institute [1]. Currently, the tool contains the entire repository of the Dawn mission's encounter with Vesta [2], and we will be adding other datasets in the future. For Vesta, this includes both the level 1A and 1B images for the Framing Camera (FC) and the level 1B spectral cubes from the Visual and Infrared (VIR) spectrometer, providing over 30,000 individual images. A key strength of the tool is providing quick and easy access of these data. The tool allows for searches based on clicking on a map or typing in coordinates. The SBIB can show an entire mission phase (such as cycle 7 of the Low Altitude Mapping Orbit) and the associated footprints, as well as search by image name. It can focus the search by mission phase, resolution or instrument. Imagery archived in the PDS are generally provided by missions in a single or narrow range of formats. To enhance the value and usability of this data to researchers, SBIB makes these available in these original formats as well as PNG, JPEG and ArcGIS compatible ISIS cubes [3]. Additionally, we provide header files for the VIR cubes so they can be read into ENVI without additional processing. Finally

    Life drawing sessions, where individuals produce drawings of the human figure from observations of a live model, may contain embodying elements that promote healthier body image. Two pilot studies were conducted to test this hypothesis. In Study 1, 138 individuals recruited from life drawing sessions in London, UK, estimated how many sessions they had attended in their lifetime and completed measures of negative and positive body image. In women, greater attendance was significantly associated with higher body appreciation and lower drive for thinness and social physique anxiety. In men, greater attendance was significantly associated with higher body appreciation, but not drive for muscularity or social physique anxiety. In Study 2, 37 women took part in a life drawing session for the first time. Compared to pre-session scores, participants had significantly more positive state body image and appearance satisfaction after the session. The findings of these studies suggest that life drawing may promote healthier body image, particularly among women, but further research is needed.

    Successful restoration of wetland ecosystems requires knowledge of wetland hydrologic patterns and an understanding of how those patterns affect wetland plant and animal populations.Within the Everglades, Florida, USA restoration, an applied science strategy including conceptual ecological models linking drivers to indicators is being used to organize current scientific understanding to support restoration efforts. A key driver of the ecosystem affecting the distribution and abundance of organisms is the timing, distribution, and volume of water flows that result in water depth patterns across the landscape. American alligators (Alligator mississippiensis) are one of the ecological indicators being used to assess Everglades restoration because they are a keystone species and integrate biological impacts of hydrological operations through all life stages. Alligator body condition (the relative fatness of an animal) is one of the metrics being used and targets have been set to allow us to track progress. We examined trends in alligator body condition using Fulton’s K over a 15 year period (2000–2014) at seven different wetland areas within the Everglades ecosystem, assessed patterns and trends relative to restoration targets, and related those trends to hydrologic variables. We developed a series of 17 a priori hypotheses that we tested with an information theoretic approach to identify which hydrologic factors affect alligator body condition. Alligator body condition was highest throughout the Everglades during the early 2000s and is approximately 5–10% lower now (2014). Values have varied by year, area, and hydrology. Body condition was positively correlated with range in water depth and fall water depth. Our top model was the “Current” model and included variables that describe current year hydrology (spring depth, fall depth, hydroperiod, range, interaction of range and fall depth, interaction of range and hydroperiod). Across all models, interaction

    We compared food intake, body mass and body composition of male and female black ducks (Anas rubripes) during winter (January-March). Birds were fed the same complete diet ad libitum on consecutive days each week without fasting (control; nine male; nine female) or with either short fasts (2 day.week-1; nine male; nine female), or long fasts (4 day.week-1; eleven male; twelve female). We continued treatments through spring (March-May) to measure the effect of intermittent fasts on body mass and egg production. Daily food intake of fasted birds was up to four times that of unfasted birds. Weekly food intake of males was similar among treatments (364 g.kg-1.week-1) but fasted females consumed more than unfasted females in January (363 g.kg-1.week-1 vs. 225 g.kg-1.week-1). Although both sexes lost 10-14% body mass, fasted females lost less mass and lipid than unfasted females during winter. Total body nitrogen was conserved over winter in both sexes even though the heart and spleen lost mass while the reproductive tract and liver gained mass. Intermittent fasting increased liver, intestinal tissue and digesta mass of females but not of males. Fasting delayed egg production in spring but did not affect size, fertility or hatching of the clutch. Females on long fasts were still heavier than controls after laying eggs. Thus black ducks combine flexibility of food intake with plasticity of digestive tract, liver and adipose tissue when food supply is interrupted during winter. Females modulate body mass for survival and defer reproduction when food supply is interrupted in spring.

    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. (PsycINFO Database Record PMID:27267500

    The hypothesis that visual perception and mental imagery are equivalent has never been explored in individuals with vision defects not preventing the visual perception of the world, such as refractive errors. Refractive error (i.e., myopia, hyperopia or astigmatism) is a condition where the refracting system of the eye fails to focus objects sharply on the retina. As a consequence refractive errors cause blurred vision. We subdivided 84 individuals according to their spherical equivalent refraction into Emmetropes (control individuals without refractive errors) and Ametropes (individuals with refractive errors). Participants performed a vividness task and completed a questionnaire that explored their cognitive style of thinking before their vision was checked by an ophthalmologist. Although results showed that Ametropes had less vivid mental images than Emmetropes this did not affect the development of their cognitive style of thinking; in fact, Ametropes were able to use both verbal and visual strategies to acquire and retrieve information. Present data are consistent with the hypothesis of equivalence between imagery and perception. PMID:23755186

    In the NASA Langley Research Center 26-inch transonic blowdown wind-tunnel, flutter speeds were measured on 1/80-th scale semispan models of the orbiter wing, the complete Space Shuttle, and intermediate component combinations. Using the doublet lattice method combined with slender body theory to calculate unsteady aerodynamic forces, subsonic flutter speeds were computed for comparison. Aerodynamic interaction was found by test and analysis to raise the flutter speed in some configurations while lowering it in others. Although at Mach number less than 0.7, predicted speeds correlated to within 6% of those measured, rapid deterioration of the agreement occurred at higher subsonic Mach numbers, especially on the more complicated configurations. Additional analysis showed that aerodynamic forces arising from body flexibility potentially can have a large effect on flutter speed, but that the current shuttle design is not so affected.

  7. Sexuality and body image in younger women with breast cancer.

    PubMed

    Schover, L R

    1994-01-01

    Breast cancer has the potential to be most devastating to the sexual function and self-esteem of premenopausal women. Nevertheless, not one study has systematically compared the impact of breast cancer treatment on sexual issues across age groups. Research shows that younger women with breast cancer have more severe emotional distress than older cohorts. In a group of patients seeking sexual rehabilitation in a cancer center, younger couples were more distressed, but also had the best prognosis with treatment. In theory, loss of a breast or poor breast appearance would be more distressing to women whose youth gives them high expectations for physical beauty. Seeking new dating relationships after breast cancer treatment is a special stressor for single women. Potential infertility also may impact on a woman's self-concept as a sexual person. Systemic treatment disrupts sexual function by causing premature menopause, with estrogen loss leading to vaginal atrophy and androgen loss perhaps decreasing sexual desire and arousability. Research on mastectomy versus breast conservation across all ages of women has demonstrated that general psychological distress, marital satisfaction, and overall sexual frequency and function do not differ between the two treatment groups. Women with breast conservation do rate their body image more highly and are more comfortable with nudity and breast caressing. There is some evidence that breast conservation offers more psychological "protection" for younger women. Research on the impact of breast reconstruction is sparse, but reveals similar patterns. Future studies should use rigorous methodology and focus on the impact of premature menopause and the effectiveness of sexual rehabilitation for younger women. PMID:7999462

    2014-01-01

    Recent research has shown that cognitive fusion underlies psychological inflexibility and in consequence various forms of psychopathology. However, the role of cognitive fusion specifically related to body image on eating psychopathology remained to be examined. The current study explores the impact of cognitive fusion concerning body image in the relation between acknowledged related risk factors and eating psychopathology in a sample of 342 female students. The impact of body dissatisfaction and social comparison through physical appearance on eating psychopathology was partially mediated by body image-related cognitive fusion. The results highlight the importance of cognitive defusion in the treatment of eating disorders. PMID:24411754

    College students' attitudes about the pervasive thin ideal have been well-studied, but the relationship between the thin ideal and youth ideal in young adults forming life-long health attitudes is understudied. This cross-sectional study examined body image, aging anxiety, ageism, and gender in a sample of 485 undergraduate students. Results from this study demonstrate associations among components of objectified body consciousness (surveillance, shame, and control), body image avoidance, aging anxiety (fear of older people, psychological concerns, physical appearance, and fear of losses), ageism, and gender. Educational efforts that address body image in relation to aging anxiety and ageism are discussed. PMID:27076487

    2014-01-01

    Background: Quadriceps function is an important measure in patients recovering postoperatively. Traditionally, strength measures that require high levels of resistance are contraindicated during the early postoperative phase. Thus it may be helpful to evaluate the utilization of other tools, such as ultrasound imaging, that allow for assessment during a position of low resistance. Hypothesis: The rectus femoris cross-sectional area (CSA) is affected by sex and body composition in healthy subjects. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: Thirty-two healthy subjects (16 women, 16 men), selected from a previously larger study, were chosen for analysis. All subjects underwent a maximal volitional isometric contraction protocol from 0° to 90° of knee motion controlled by an isokinetic dynamometer. In the contracted and resting positions, the rectus femoris CSA was measured at each angle using ultrasound imaging. The contractile index (contracted − resting CSA) was calculated at each position. Subjects were separated into 1 of 4 groups based on sex and fat percentage (low or high). These data were analyzed using mixed-factor analysis of variance (group × angle) for each variable, with a critical α level of 0.05. Results: A significant interaction was noted for the CSA of the rectus femoris at rest (P < 0.03) and during contraction (P < 0.02). For both variables, all groups performed similarly, with the exception of women with high body fat percentage. No statistically significant interaction existed for the contractile index; however, a main effect for angle (P < 0.01) was observed. Conclusion: Rectus femoris CSA appears to depend on sex as well as the body composition of individuals.

    The objectives of this study were to examine the effects of a low vs moderate rate of gain during the growing phase on empty body and carcass composition during finishing of Angus and Charolais steers of two ages. Forty-eight Angus and 48 Charolais steers that were either spring-born (OLDER) or fall-born (YOUNGER) were fed two diets (alfalfa pellets [CON] or cubed grass-alfalfa hay, wheat straw, cottonseed hulls, and soybean meal [RES]) for a growing period followed by a conventional feedlot period. The feedlot period started when the YOUNGER-CON steers weighed the same as the OLDER-RES steers. At that time, an interaction of age x diet occurred in empty body fat content (P < .10), whereas breed and age x diet affected carcass fat content (P < .01). OLDER-CON steers were larger (average 378 kg empty BW) and fatter than the other, smaller groups (average 222 kg). Angus carcasses were fatter than Charolais carcasses (P < .01). At the end of the finishing phase, compensating steers (OLDER-RES) had fatter carcasses than OLDER-CON steers. Empty body fat content was affected by a breed x age x diet interaction (P < .10). Allometric regressions (Y = aXb) of fat on empty BW indicated that empty body fat accretion was greater in Angus than in Charolais and in YOUNGER than in OLDER steers. A breed x age x diet interaction (P < .10) indicated that OLDER-Angus had higher fat accretive rates than YOUNGER-Angus, whereas OLDER-CON-Charolais steers deposited fat more slowly than the remaining groups. These data suggest that steers receiving feedlot diets at light weights, whether young in age or previously restricted, accumulate fat more rapidly than do larger steers. This feeding strategy may be an advantage in late-maturing types, but moderate growth through approximately 75% of slaughter weight is recommended for early-maturing types.

    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.

    Sociocultural norms pertaining to an ideal of thinness for women likely play a role in the development and maintenance of disturbance in body image, and by extension, disordered eating. However, competing norms associated with feminism may buffer women from pressures associated with achieving the thin ideal. The present study explored the relationship between feminist ideology, empowerment, and self-efficacy relative to body image and eating behavior with a sample of U.S. undergraduate women (N=318) attending a southeastern U.S. mid-sized university. In planned hierarchical multiple regression analyses, endorsement of feminist ideology predicted perceptions of positive body image, but did not appear to predict disordered eating. Self-efficacy emerged as a robust predictor of positive body image and lower disordered eating even after controlling for perceptions of personal empowerment and feminism. Results, although limited by correlational data, suggest that self-efficacy may protect college-aged women from disordered eating and negative body image.

    BACKGROUND Elective aesthetic surgeries are increasing in the Iranian population with reasons linked to body image dissatisfaction and psychological symptoms. This study compared the body image dissatisfaction and psychological symptoms among invasive and minimally invasive aesthetic surgery patients and a control group. METHODS Data from 90 participants (invasive aesthetic surgery=30 Ss, minimally invasive aesthetic surgery=30 Ss, and control group=30 Ss) were included. Subjects were assessed on body image dissatisfaction and psychological symptoms to provide an evidence for a continuum of body image dissatisfaction, anxiety, depression and interpersonal sensitivity in invasive and minimally invasive aesthetic surgery clients. RESULTS Between the three groups of invasive, minimally invasive aesthetic surgeries and control on body image dissatisfaction and psychological symptoms (anxiety, depression and interpersonal sensitivity), there was a significant difference. CONCLUSION These findings have implications for pre-surgical assessment as well as psychological interventions rather than invasive medical interventions at first step. PMID:27579270

This article uses architectural theory to show that some hygienic models of transgender-such as "original plumbing"-are less about explaining our genders to ourselves and more about (1) communicating our "fuckability" to (presumably non-trans) others and (2) codifying subtle and often problematic beliefs about the relationship between architecture and the body.

    This study explored self-compassion as a mediator between body dissatisfaction, social comparison based on body image and quality of life in 662 female college students. Path analysis revealed that while controlling for body mass index, self-compassion mediated the impact of body dissatisfaction and unfavourable social comparisons on psychological quality of life. The path model accounted for 33 per cent of psychological quality of life variance. Findings highlight the importance of self-compassion as a mechanism that may operate on the association between negative body image evaluations and young women's quality of life.

    HIV infection and its treatment can have significant effects on physical appearance and functioning, which can affect self-perceived body image. We assessed the psychometric properties of a newly developed Body Image Scale (BIS), a subjective measure of body image perception in persons with HIV infection, as well as the scale's relationship to disease progression, symptoms, and demographic factors. HIV-positive men (n = 129) and women (n = 21) attending two outpatient HIV clinics were administered the BIS survey along with a one-page questionnaire. A subset (n = 38) were administered the survey on two occasions to assess test-retest reliability. Nearly half of the sample (46%) had AIDS and 25% had a CD4 count below 200 cells/mm(3) within the prior 3 months. The BIS had unidimensional factor structure, good internal consistency reliability (Chronbach alpha = 0.91), and good test-retest reliability (r = 0.71, p < 0.001) after controlling for the length of interval between assessments. Patients' current perception of their body image was worse then what they perceived it to be prior to HIV infection (p < 0.001), but better than their perception of how others view people with HIV (p < 0.001). The presence of symptomatic disease (p < 0.001) and a diagnosis of AIDS (p = 0.02) were associated with a less favorable body image, although laboratory markers of disease progression (CD4 count and plasma HIV viral load) were not. We conclude that the BIS has good construct validity and is a highly reproducible measure of self-perceptive of body image in HIV-infected patients. Further exploration of its relationship to psychological well being, medication adherence and other aspects of medical care is indicated.

    Purpose Precocious puberty (PP) is associated with psychological and behavioral problems. This study aimed to evaluate the perception of body image and depression in girls with PP receiving gonadotropin-releasing hormone (GnRH) analogue therapy. Methods From March to August 2013, 82 girls with PP receiving GnRH analogue therapy were enrolled. Height, weight, body mass index, and stages of pubertal development were assessed. Participants completed a series of questionnaires on their body image perception and pubertal self-assessment. The depression score was calculated using the Korean Kovacs' Children's Depression Inventory. Results The patients perceived their body to be more obese than the controls did. The mean depression score did not differ between the patients and controls. The mean depression scores according to Tanner stages (1: prepubertal, 2: early pubertal, and 3–5: mid to late pubertal stage) by self-assessment were 5.2±3.6, 6.8±4.9, and 11.4±10.1 (P<0.05), respectively. The perception of overall body build and figure (%) and the mean depression scores in patients were: dissatisfied (25.6%, 9.7±7.8) and satisfied (74.4%, 5.5±3.4) (P<0.05). In multiple linear regression analysis, self-T3 (Tanner stage 3–5 by self-awareness) and dissatisfaction about overall body build and figure were found to significantly affect the depression score(P<0.05). Conclusion The perception of pubertal status and satisfaction about height or weight are unrelated to objective physical findings. Patients with PP are prone to distorted perception about their body image and breast development. Such incorrect body image seems to contribute to depression score. PMID:27777908

    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.

  5. 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

    There are many congenital, neoplastic, inflammatory, and infectious processes in the pediatric patient for which whole-body imaging may be of benefit diagnostically and prognostically. With recent improvements in magnetic resonance imaging (MRI) hardware and software and resultant dramatically reduced scan times, imaging of the whole body with MRI has become a much more practicable technique in children. Whole-body MRI can provide a high level of soft tissue and skeletal detail while avoiding the exposure to ionizing radiation inherent to computed tomography and nuclear medicine imaging techniques. This article reviews the more common current whole-body MRI techniques in children and the primary pathologies for which this imaging modality may be most useful to the radiologists and referring clinicians.

  7. Do cigarette taxes affect children's body mass index? The effect of household environment on health.

    PubMed

    Mellor, Jennifer M

    2011-04-01

    Several recent studies demonstrate a positive effect of cigarette prices and taxes on obesity among adults, especially those who smoke. If higher cigarette costs affect smokers' weights by increasing calories consumed or increasing food expenditures, then cigarette taxes and prices may also affect obesity in children of smokers. This study examines the link between child body mass index (BMI) and obesity status and cigarette costs using data from the National Longitudinal Survey of Youth-79 (NLSY79). Controlling for various child, mother, and household characteristics as well as child-fixed effects, I find that cigarette taxes and prices increase BMI in the children of smoking mothers. Interestingly, and unlike previous research findings for adults, higher cigarette taxes do not increase the likelihood of obesity in children. These findings are consistent with a causal mechanism in which higher cigarette costs reduce smoking and increase food expenditures and consumption in the household.

    The study objective was to compare the effect of different angles of lying positions on the physiological indices of patients with cirrhosis ascites. Chronic liver disease and cirrhosis were ranked 9th among the top 10 causes of death. Ascites is the most common cirrhosis comorbidity. Body posture can affect pulmonary ventilation and arterial oxygen partial pressure, making it an important clinical nursing intervention significantly affecting patient recovery. This was a quasi-experimental study design. From a medical center in Taiwan, 252 patients with cirrhosis ascites were recruited. Subjects were randomly divided into three groups by bed angle: 15°, 30°, and 45°. Physiological indices were measured at 5, 10, 15, 20, 25, and 30 minutes to determine any changes in heart rate, respiration rate, and oxygenation saturation. Data analysis included descriptive statistics and the generalized estimating equation for statistical analysis with significance set at α= 0.05. After controlling for confounding variables, the three groups differed significantly in heart rate at 20, 25, and 30 minutes, oxygenation saturations at 15 and 20 minutes, and respiration rate at 5 and 10 minutes (α< 0.05). Body posture can affect pulmonary ventilation and arterial oxygen partial pressure and is thus an important clinical nursing intervention that significantly affects the recovery of patients. When caring for patients with cirrhosis ascites, nurses should help patients to choose the most comfortable angle for them with no particular restrictions. Our results can be used to guide nurses in making a plan for health education and nursing that improves the quality of care for patients with chronic liver disease and cirrhosis patients with ascites.

    Background: Obesity has become epidemic worldwide and 31.0% of Korean adults are obese. Obesity is the main cause of chronic diseases, such as diabetes, hypertension, cardiac disease, and cancer. The purpose of the study was to examine obesity, body image, depression, and weight-control behaviour among Korean female university students and investigate the differences in body image, depression, and weight-control behaviour with respect to obesity. Methods: This study examined obesity, body image, depression, and weight control in 700 female university students from 4 universities in South Korea. To evaluate obesity, both objective obesity (body mass index [BMI]) and subjective obesity (subjectively perceived) were measured. Results: There was a significant difference between objective and subjective obesity (χ2 = 231.280, P < 0.001). In addition, the objective obesity group had the lowest body image score (F = 19.867, P < 0.001) and difference in weight-control behaviour (F = 3.145, P = 0.045). Further, the subjective obesity group had the lowest body image score (F = 58.281, P < 0.001). The results revealed a statistically significant difference in body image and weight-control behaviour with respect to objective obesity. Conclusion: Objective and subjective obesity was negatively associated with body image, and no relationships between objective or subjective obesity and depression. PMID:25337594

    To report the results of a systematic review and meta-analysis examining whether weight loss interventions improve body image in obese/overweight individuals. Medline, Current Contents, and the Cochrane database were searched to identify studies involving obese/overweight adults who were enrolled in weight loss interventions in which body image was quantitatively assessed. Outcomes assessed were changes in body shape concern, body size dissatisfaction, and body satisfaction (intervention vs comparator/control group). Seven studies were included in the systematic review (4 in the meta-analysis). All but 1 study involved female participants only. The type of weight loss intervention varied between studies as did the type of control/comparator group. In 3 studies, there was no significant difference in body image outcomes, whereas in 4 studies, improvement in body image was significantly more pronounced in the intervention vs the control/comparator group. Meta-analysis revealed that improvements in body shape concern (standardized difference: -0.52; 95% confidence interval [CI]: -1.04 to 0.00), body size dissatisfaction (standardized difference: -0.66; 95% CI: -0.88 to -0.45), and body satisfaction (standardized difference: 0.74; 95% CI: 0.09 to 1.38) significantly favored the intervention over the comparator/control group (P<0.05). The results of this systematic review/meta-analysis lend support to the notion that weight loss interventions may improve body image. This is a noteworthy finding that has clear clinical applicability because body image affects psychological well-being and the ability of an individual to maintain weight loss. Future research should determine which weigh loss interventions are associated with optimal improvements in body image and maintenance of weight loss. PMID:25946138

    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.

    Multiple myeloma (MM) is the second most common hematological malignancy. Although it can affect different organs, the bone compartment stands out both in terms of prevalence and clinical impact. Despite the striking advances in MM therapy, bone disease can remarkably affect the patient's quality of life. The occurrence and extension of bone marrow and extra-medullary involvement should be carefully assessed to confirm the diagnosis, to locate and whenever possible prevent dreadful complications such as pathological fractures and spinal cord compression, and to establish suitable therapeutic measures. Many imaging techniques have been proposed for the detection of MM skeletal involvement. With the development of more sophisticated imaging tools, it is time to use the right technique at the right time. Based on the review of the literature and our own experience, this article discusses advantages and disadvantages of the different imaging methods in the work-up of MM patients, with particular emphasis on the role that PET/CT can play. It is emphasized that whole body low-dose computed tomography should be the preferred imaging technique at baseline. However, bone marrow infiltration and extra-medullary manifestations are better detected by whole body magnetic resonance imaging. Positron emission tomography/computed tomography, on the other hand, combines the benefits of the two mentioned imaging procedures and is particularly useful not only for the detection of osteolytic lesions unrevealed by conventional X-ray, but also in the assessment of prognosis and therapeutic response.

    Methods: Ten RBD patients (three with disorders of bodily representations) were asked to report whether movements of their right hand induced any illusory somatic or motor sensations. Inquiries on anomalous sensation of movement of the left hand were carried out while subjects: 1) observed the moving hand in a mirror propped vertically along the parasagittal plane; 2) looked directly at the moving hand; 3) looked at the still hand; 4) kept their eyes closed. Twelve healthy subjects served as controls. Results: Movement of the right hand induced a very clear sensation of movement of the left, contralesional hand in two patients affected by body image disorders. Remarkably, this occurred mainly while subjects were looking in the mirror, that is, when conflicts between visual, somatic, and motor information were maximal. In no condition did control subjects report any consistent anomalous evoked movement or sensation. Conclusions: Illusory movements of the left, plegic hand contingent upon sensorimotor conflicts can be evoked in brain damaged patients with body image disorders. PMID:15489402

    This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.

    Body size misperception is common amongst the general public and is a core component of eating disorders and related conditions. While perennial media exposure to the "thin ideal" has been blamed for this misperception, relatively little research has examined visual adaptation as a potential mechanism. We examined the extent to which the bodies of "self" and "other" are processed by common or separate mechanisms in young women. Using a contingent adaptation paradigm, experiment 1 gave participants prolonged exposure to images both of the self and of another female that had been distorted in opposite directions (e.g., expanded other/contracted self), and assessed the aftereffects using test images both of the self and other. The directions of the resulting perceptual biases were contingent on the test stimulus, establishing at least some separation between the mechanisms encoding these body types. Experiment 2 used a cross adaptation paradigm to further investigate the extent to which these mechanisms are independent. Participants were adapted either to expanded or to contracted images of their own body or that of another female. While adaptation effects were largest when adapting and testing with the same body type, confirming the separation of mechanisms reported in experiment 1, substantial misperceptions were also demonstrated for cross adaptation conditions, demonstrating a degree of overlap in the encoding of self and other. In addition, the evidence of misperception of one's own body following exposure to "thin" and to "fat" others demonstrates the viability of visual adaptation as a model of body image disturbance both for those who underestimate and those who overestimate their own size.

    Body size misperception is common amongst the general public and is a core component of eating disorders and related conditions. While perennial media exposure to the “thin ideal” has been blamed for this misperception, relatively little research has examined visual adaptation as a potential mechanism. We examined the extent to which the bodies of “self” and “other” are processed by common or separate mechanisms in young women. Using a contingent adaptation paradigm, experiment 1 gave participants prolonged exposure to images both of the self and of another female that had been distorted in opposite directions (e.g., expanded other/contracted self), and assessed the aftereffects using test images both of the self and other.

    Atrazine is the one of the most widely used herbicides in the United States and non-target organisms may encounter it in the environment. Atrazine is known to affect male reproduction in both vertebrates and invertebrates but less is known about its effects on other fitness traits. Here we assessed the effects of five different chronic exposure levels on a variety of fitness traits in Drosophila melanogaster. We measured male and female longevity, development time, proportion pupated, proportion emerged, body size, female mating rate, fertility and fecundity. Atrazine exposure decreased the proportion pupated, the proportion emerged and adult survival. Development time was also affected by atrazine and exposed flies pupated and emerged earlier than controls. Although development time was accelerated, body size was actually larger in some of the exposures. Atrazine exposure had no effect on female mating rate and the effects on female fertility and fecundity were only observed in one of the two independent experimental blocks. Many of the traits showed non-monotonic dose response curves, where the intermediate concentrations showed the largest effects. Overall this study shows that atrazine influences a variety of life history traits in the model genetic system, D. melanogaster, and future studies should aim to identify the molecular mechanisms of toxicity.

    Organisms are constantly subjected to stressful stimuli that affect numerous physiological processes and activate the hypothalamo-pituitary-adrenal (HPA) axis, increasing the release of glucocorticoids. Exposure to chronic stress is known to alter basic mechanisms of the stress response. The purpose of the present study was to compare the effect of two different stress paradigms (chronic restraint or variable stress) on behavioral and corticosterone release to a subsequent exposure to stressors. Considering that the HPA axis might respond differently when it is challenged with a novel or a familiar stressor we investigated the changes in the corticosterone levels following the exposure to two stressors: restraint (familiar stress) or forced novelty (novel stress). The changes in the behavioral response were evaluated by measuring the locomotor response to a novel environment. In addition, we examined changes in body, adrenals, and thymus weights in response to the chronic paradigms. Our results showed that exposure to chronic variable stress increased basal plasma corticosterone levels and that both, chronic restraint and variable stresses, promote higher corticosterone levels in response to a novel environment, but not to a challenge restraint stress, as compared to the control (non-stressed) group. Exposure to chronic restraint leads to increased novelty-induced locomotor activity. Furthermore, only the exposure to variable stress reduced body weights. In conclusion, the present results provide additional evidence on how chronic stress affects the organism physiology and point to the importance of the chronic paradigm and challenge stress on the behavioral and hormonal adaptations induced by chronic stress.

    Six studies were performed regarding the effects of atrazine, the most frequently detected pesticide in fresh water in the US, on developing Xenopus laevis tadpoles exposed 5 days post-hatch through Nieuwkoop Faber Stage 62. The levels of atrazine tested included those potentially found in puddles, vernal ponds and runoff soon after application (200 and 400 μg/L) and a low level studied by a number of other investigators (25 μg/L). One study tested 0, 25 and 200 μg/L, another tested 0, 200 and 400 μg/L, while the remaining four studies tested 0 and 400 μg/L. During all exposures, mortality, growth, metamorphosis, sex ratio, fat body (a lipid storage organ) size and liver weights, both relative to body weight, were evaluated. In selected studies, feeding behavior was recorded, livers and fat bodies were histologically evaluated, liver glycogen and lipid content were determined by image analysis, and immunohistochemical detection of activated caspase-3 in hepatocytes was performed. The NOEC was 25 μg/L. None of these exposure levels changed sex ratios nor were intersex gonads noted, however, no definitive histological evaluation of the gonads was performed. Although a marginal increase in mortality at the 200 μg/L level was noted, this was not statistically significant. Nor was there an increase in mortality at 400 μg/L versus controls. At the 400 μg/L level, tadpoles were smaller than controls by 72 h of exposure and remained smaller throughout the entire exposure. Appetite was not decreased at any exposure level. Slowed metamorphosis was noted only at 400 μg/L in two of five studies. Livers were significantly smaller in the study that tested both 200 and 400 μg/L, yet no pathological changes or differences in glycogen or lipid stores were noted. However, livers from 400 μg/L exposed tadpoles had higher numbers of activated caspase-3 immunopositive cells suggesting increased rates of apoptosis. Fat body size decreased significantly after exposure to 200

    Matrix land-use intensification is a relatively recent and novel landscape change that can have important influences on the biota within adjacent habitat patches. While there are immediate local changes that it brings about, the influences on individual animals occupying adjacent habitats may be less evident initially. High-intensity land use could induce chronic stress in individuals in nearby remnants, leading ultimately to population declines. We investigated how physiological indicators and body condition measures of tropical forest-dependent birds differ between forest adjacent to surface mining sites and that near farmlands at two distances from remnant edge in southwest Ghana. We used mixed effects models of several condition indices including residual body mass and heterophil to lymphocyte (H/L) ratios (an indicator of elevated chronic stress) to explore the effect of matrix intensity on forest-dependent passerines classed as either sedentary area-sensitive habitat specialists or nomadic generalists. Individual birds occupying tropical forest remnants near surface mining sites were in poorer condition, as indicated by lower residual body mass and elevated chronic stress, compared to those in remnants near agricultural lands. The condition of the sedentary forest habitat specialists white-tailed alethe, Alethe diademata and western olive sunbird, Cyanomitra obscura was most negatively affected by high-intensity surface mining land-use adjacent to remnants, whereas generalist species were not affected. Land use intensification may set in train a new trajectory of faunal relaxation beyond that expected based on habitat loss alone. Patterns of individual condition may be useful in identifying habitats where species population declines may occur before faunal relaxation has concluded. PMID:26107179

    Larger birds are generally more strongly affected by habitat loss and fragmentation than are smaller ones because they require more resources and thus larger habitat patches. Consequently, conservation actions often favor the creation or protection of larger over smaller patches. However, in grassland systems the boundaries between a patch and the surrounding landscape, and thus the perceived size of a patch, can be indistinct. We investigated whether eight grassland bird species with different body sizes perceived variation in patch size and landscape structure in a consistent manner. Data were collected from surveys conducted in 44 patches of northern tallgrass prairie during 1998-2001. The response to patch size was very similar among species regardless of body size (density was little affected by patch size), except in the Greater Prairie-Chicken (Tympanuchus cupido), which showed a threshold effect and was not found in patches smaller than 140 ha. In landscapes containing 0%-30% woody vegetation, smaller species responded more negatively to increases in the percentage of woody vegetation than larger species, but above an apparent threshold of 30%, larger species were not detected. Further analyses revealed that the observed variation in responses to patch size and landscape structure among species was not solely due to body size per se, but to other differences among species. These results indicate that a stringent application of concepts requiring larger habitat patches for larger species appears to limit the number of grassland habitats that can be protected and may not always be the most effective conservation strategy. ??

    While individual cases of eating disorder (ED) patients with disabilities have been reported, there has been little synthesis of their experiences of body image and thin idealization. This study reviews 19 published clinical reports of ED patients with sensory, mobility-related, or intellectual disabilities and evaluates the extent to which their experiences align with or challenge current conceptions of body image in ED. ED patients with visual impairment reported a profound disturbance of body image, perceived intersubjectively and through tactile sensations. Reducing dependence in mobility was an important motivation to control body size for ED patients with mobility-related disabilities. ED as a way of coping with and compensating for the psychosocial consequences of disability was a recurrent theme for patients across a range of disabilities. These experiential accounts of ED patients with disabilities broaden current understandings of body image to include touch and kinaesthetic awareness, intersubjective dynamics, and perceptions of normalcy.

  9. Is Intensive Measurement of Body Image Reactive? A Two-Study Evaluation Using Ecological Momentary Assessment Suggests Not

    Intensive assessment methods (e.g., Ecological Momentary Assessment [EMA]) are increasingly used to capture body image experiences in daily life. One concern with EMA is multiple assessments may increase reactivity to internal or external cues, potentially biasing measurement. Reactivity to EMA was evaluated in two studies (Study 1: N = 63 female undergraduates, Study 2: N = 131 women with high body dissatisfaction/disordered eating). Participants completed five daily surveys on handheld computers for 1–2 weeks and body image-related questionnaires at the start and end of each study. Results showed no systematic changes in pre- and post-EMA measures or momentary EMA reports, suggesting women were not reactive to the EMA protocols. Completing 1–2 weeks of EMA does not appear to affect body dissatisfaction, mood, or attitudes in non-clinical or at-risk samples of women. These studies provide evidence that EMA methods can be used to assess real-world body image experiences without undue concern about measurement reactivity. PMID:22999225

    "Fat talk" describes women discussing their bodies disparangingly for impression management while interacting with one another. This study examined whether college females deliberately alter their self-reported body image according to characteristics of their prospective audience. This study was a mixed experimental design with four audience conditions (private, public, female audience, male audience) as the between-subjects factor and time across trials as the within-subjects factor using college females as participants (N=100). Pre versus posttest changes on the Body Esteem Scale (BES) and the Body Weight Figure Assessment (BWFA) served as the dependent variables. It was hypothesized that body image would decrease to indicate self-derogation (fat talk) in the public audience and female audience conditions, whereas body image would increase in the male audience condition. These hypotheses were not supported using repeated measures ANOVA. Strengths and weaknesses of the study are discussed. PMID:17336794

    One of the leading causes of medical malpractice claims in emergency medicine is the misdiagnosis of the presence of foreign bodies. Radiolucent foreign bodies are especially difficult to differentiate from surrounding soft tissue, gas, and bone using existing clinical imaging modalities. Because many radiolucent foreign bodies have sufficient contrast for imaging in the optical domain, we are exploring the use of laser-induced optoacoustic imaging for the detection of foreign bodies, especially in orbital and craniofacial injuries, in which the foreign bodies are likely to lie within the penetration depth of visible and near infrared wavelengths. In order to evaluate the performance of optoacoustic imaging for clinical detection and characterization, common foreign bodies have been scanned over a range of visible and near infrared wavelengths to obtain the spectroscopic properties of the materials commonly associated with these foreign bodies. The foreign bodies are also being embedded in realistic ex vivo tissue phantoms to evaluate the changes that may occur in the spectroscopic absorption of the materials due to the interaction with tissue absorbers. Ultimately, we anticipate that spectroscopic characterization will help identify specific wavelengths to be used for imaging foreign bodies that will provide useful diagnostic data about the material properties of the object, thereby enabling the characterization, as well as the location, of the objects. This information will aid the clinician in choosing the optimal treatment course for the patient.

    This study investigated the impact of acculturative stress on psychological well-being and body image disturbance in a sample of female and male Hispanic individuals. The unique protective effects of differing social support sources, including family and peer support, were examined against acculturative stress and body image disturbance. A total of 399 participants of Hispanic origin were recruited from Texas Tech University in West Texas. Students completed a battery of measures of acculturative stress and internalization of the thin ideal, as well as perceived social support. Hierarchical regression analyses indicated that acculturative stress is a significant positive predictor of body image disturbance among Hispanic college students. Thin ideal internalization was found to mediate this relationship such that acculturative stress was associated with heightened body image disturbance through its impact on thin ideal internalization. Social support significantly reduced acculturative stress as well as body image disturbance but did not moderate the relation between these 2 factors. Results highlight the importance of considering acculturative stress as a strong predictor of body image disturbance among college students of Hispanic origin. The mechanisms of influence of acculturative stress on body image disturbance are discussed in relation to thin ideal internalization. The protective role of social support on these negative psychological outcomes is also clarified. This study is the first to examine these issues in a sample of female and male Hispanic college students and provides avenues for clinical interventions and future trials with diverse populations.

    Purpose. Excess growth hormone secretion in adults results in acromegaly, a condition in which multiple physical changes occur including bony and soft tissue overgrowth. Over time these changes can markedly alter a person's appearance. The aim of this study was to compare body image disturbance in patients with acromegaly to those with nonfunctioning pituitary adenomas (NFAs) and controls and assess the impact of obesity in these groups. Methods. A cross-sectional survey including quality of life, body image disturbance, anxiety and depression measures, growth hormone, and BMI measurement was carried out. Results. The groups did not differ with respect to body image disturbance. However separate analysis of obese participants demonstrated relationships between mood scales, body image disturbance, and pain issues, particularly for acromegaly patients. Conclusions. While the primary hypothesis that acromegaly might be associated with body image disturbance was not borne out, we have shown that obesity together with acromegaly and NFA can be associated with body image issues, suggesting that BMI rather than primary diagnosis might better indicate whether patients might experience body image disturbance problems.

    The role that body image plays in the psychological adjustment of kidney-transplant recipients is an understudied issue. In the current study, the association between three variables - (a) body-image dissatisfaction, (b) quality of life (QOL), and (c) psychological distress - was investigated. The research participants were 45 kidney-transplant recipients who were under follow-up care at the Transplant Unit of the Tel-Aviv Medical Center (Israel). Body image, psychological distress, and QOL were measured using self-report questionnaires [Body-Image Ideals Questionnaire (BIIQ), Brief Symptoms Inventory (BSI), and SF-12]. Medical and background data were collected from medical and administrative records. The findings indicated an association between higher level of body-image dissatisfaction and a decrease in several quality-of-life dimensions (role emotional, physical pain, general health, and social functioning), and with an increase in psychological distress. These findings highlight the importance of body-image dissatisfaction as a factor that is associated with QOL and psychological distress among kidney-transplant recipients. Body image warrants further attention and should be screened and treated among those who demonstrate high levels of dissatisfaction. PMID:25343489

    We aimed to evaluate the influence of image reduction using a bi-cubic interpolation method on the accuracy of detection of clustered microcalcifications (MCLs) and masses on digital mammograms. Digital mammograms (n=194) of 97 subjects were selected retrospectively, comprising 47 patients with clustered MCLs or masses and 52 controls. Images were acquired in the craniocaudal view by phase-contrast mammography (PCM). Original PCM images comprised 25-μm pixels. The reduced images converted from the originals by bi-cubic interpolation were of 50-μm pixel size. Five observers independently interpreted all images, and rated their confidence concerning the presence of lesions on a continuous 0-100 scale. Receiver-operating characteristic (ROC) analysis was performed using the jackknife method and LABMRMC program. Differences in areas under the curve (AUC) values based on 95% confidence intervals were evaluated. The average AUC values for detection of masses were 0.8435 and 0.8646 for the original and reduced images, respectively. The difference between the average AUC values was not statistically significant (p=0.5855). Average AUC values for clustered MCLs detection were 0.9273 and 0.9574 for the original and reduced images, respectively. This difference was not statistically significant (p=0.1949). Detection of masses and clustered MCLs on digital mammograms was unaffected by bi-cubic interpolation image reduction.

    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.

    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

    Background 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). Methods 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. Results 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). Conclusion 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. PMID:24663958

Methods The sample (n = 671) represented low-income and middle-income women, aged 21–55 years, living in Bogotá, who had children in the public school system. We measured height and weight to calculate body mass index (BMI, kg/m2) and defined two dichotomous outcomes: overweight/obesity (BMI ≥25) and obesity (BMI ≥30). Women reported sociodemographic information and used the Stunkard Figure Rating Scale to identify the silhouette that most closely resembled their body shape (current), what they would like to look like (ideal), and what they considered healthiest (healthiest). We estimated body dissatisfaction by subtracting the ideal from the current scores. Results The prevalences of overweight/obesity and obesity, based on measured height and weight, were 41.9% and 11.6%, respectively. Age, being married, and being born in Bogotá were positively associated with overweight/obesity but not with obesity alone, whereas the number of household assets and parity were both positively related to obesity. Women with higher education or who lived in wealthier neighborhoods identified ideal shapes that were thinner than those identified by their less educated or poorer counterparts (p = 0.03 and p = 0.004, respectively). Higher education was also associated with the selection of thinner body shapes as healthiest (p = 0.02). BMI and education were both positively related to body dissatisfaction (p < 0.0001 and p = 0.04, respectively). Conclusions Indicators of higher socioeconomic status (SES) (e.g., having more household assets) are associated with obesity. Perception of slimmer body shapes as ideal and healthiest and higher body dissatisfaction are associated with higher education. PMID:19630551

    Body packing is the ingestion or insertion in the human body of packed illicit substances. Over the last 20 years, drug smuggling has increased global and new means of transport of narcotics have emerged. Among these, the most frequent one is the gastrointestinal tract: from mouth to anus, vagina, and ears. Cocaine is one of the most traded drugs, followed by heroin. Condoms, latex gloves, and balloons are typically used as drug packets for retention in the body. There are different radiologic modalities to detect illicit drugs in body packing: Plain radiography, computed tomography (CT), ultrasound, and magnetic resonance. Current protocols recommend the use of radiography to confirm packet retention and, in case of doubt, the use of abdominal CT scan with reduced mAs. In case of packet rupture, catastrophic effects can occur. Management of patients carrying packets of drugs is a recurrent medico-legal problem. To improve diagnostic accuracy and prevent hazardous complications, radiologists and emergency physicians should be familiar with radiologic features of body packing. The radiologist plays both a social and a medico-legal role in their assessment, and it should not be limited only to the identification of the packages but must also provide accurate information about their number and their exact location. In this review, we focus on diagnostic errors and medico-legal issues related to the radiological assessment of body packers. PMID:26063072

    Objectives A commonly attributed cause of sexual body image dissatisfaction is pornography use. This relationship has received little verification. Methods The relationship between sexual body image dissatisfaction and Internet pornography use was tested using a large-N sample of Dutch respondents. Results/Conclusion Penis size dissatisfaction is associated with pornography use. The relationship between pornography use and breast size dissatisfaction is null. These results support prior speculation and self-reports about the relationship between pornography use and sexual body image among men. These results also support a prior null finding of the relationship between breast size satisfaction for women and pornography use. PMID:26918066

    The effect of strength training on body image is understudied. The Strong Women Program, a 10-week, twice weekly strength-training program, was provided by Extension agents to 341 older rural women (62±12 years); changes in body image and other psychosocial variables were evaluated. Paired-sample t-test analyses were conducted to assess mean differences pre- to post-program. Strength training was associated with significant improvements in several dimensions of body image, health-related quality of life, and physical activity behaviors, satisfaction, and comfort among rural aging women—an often underserved population that stands to benefit considerably from similar programs.

    Sex roles dictate acceptable attitudes and preferences for men and women. Further, perception of ideal body type is one attitude and preference that may be associated with sex-role orientation. Therefore, the current study examined the association between sex-role orientation and men's and women's reports of their preferred body type and their views of others' preferred body type for men and women. Responses from 172 university students indicated sex-role associations with participants' personal body-type preferences and participants' perceptions of the body types others prefer. Analysis indicates that a more masculine sex-role orientation was associated with men's and women's perceptions of larger ideal body images. Results are discussed in terms of the association between sex-role orientation and possible susceptibility to societal standards of ideal body images.

    Very few empirical studies have investigated the effect that culturally relevant beauty ideals (such as long, straight hair and lighter skin tones) have on Black women's feelings about their physical appearance. The current investigation examined the direct effect of internalizing idealized media images on Black women's body esteem and appearance satisfaction. The indirect effects of: (a) the presumed influence of the media images on African American men, and (b) feelings of invisibility were also tested. Using an online survey, the sample included 230 women who identified as African American and/or Black American. Through structural equation modeling (SEM), findings reveal that participants' body esteem was directly negatively impacted by higher levels of internalization of idealized media images. Further, the findings support the idea that higher levels of internalization of media lead to a greater presumed influence of media on men, which leads to higher feelings of invisibility, ultimately leading to lower body esteem. Finally, there was evidence to suggest that appearance satisfaction was not directly negatively affected by internalization of media images but was negatively impacted when the images are presumed to have a higher influence on African American men.

    Positron emission tomography (PET) is the highest sensitivity technique for human whole-body imaging studies. However, current clinical PET scanners do not make full use of the available signal, as they only permit imaging of a 15-25 cm segment of the body at one time. Given the limited sensitive region, whole-body imaging with clinical PET scanners requires relatively long scan times and subjects the patient to higher than necessary radiation doses. The EXPLORER initiative aims to build a 2-meter axial length PET scanner to allow imaging the entire subject at once, capturing nearly the entire available PET signal. EXPLORER will acquire data with ~40-fold greater sensitivity leading to a six-fold increase in reconstructed signal-to-noise ratio for imaging the total body. Alternatively, total-body images with the EXPLORER scanner will be able to be acquired in ~30 seconds or with ~0.15 mSv injected dose, while maintaining current PET image quality. The superior sensitivity will open many new avenues for biomedical research. Specifically for cancer applications, high sensitivity PET will enable detection of smaller lesions. Additionally, greater sensitivity will allow imaging out to 10 half-lives of positron emitting radiotracers. This will enable 1) metabolic ultra-staging with FDG by extending the uptake and clearance time to 3-5 hours to significantly improve contrast and 2) improved kinetic imaging with short-lived radioisotopes such as C-11, crucial for drug development studies. Frequent imaging studies of the same subject to study disease progression or to track response to therapy will be possible with the low dose capabilities of the EXPLORER scanner. The low dose capabilities will also open up new imaging possibilities in pediatrics and adolescents to better study developmental disorders. This talk will review the basis for developing total-body PET, potential applications, and review progress to date in developing EXPLORER, the first total-body PET scanner.

    The impressive development of computed tomography (CT) techniques such as the three dimensional helical CT produces a spatial image of the thoracic skull. At the beginning of the 16th century Leonardo da Vinci drew with great precision the thorax oseum. These drawings show an outstanding similarity with the images obtained by three dimensional helical CT. The cumbersome task of the Renaissance genius is a prime example of the careful study of human anatomy. Modern imaging techniques require perfect anatomic knowledge of the human body in order to generate exact interpretations of images. Leonardo's example is alive for anybody devoted to modern imaging studies.

  9. The roles of the amygdala in the affective regulation of body, brain, and behaviour

    Despite the great amount of knowledge produced by the neuroscientific literature on affective phenomena, current models tackling non-cognitive aspects of behaviour are often bio-inspired but rarely bio-constrained. This paper presents a theoretical account of affective systems centred on the amygdala (Amg). This account aims to furnish a general framework and specific pathways to implement models that are more closely related to biological evidence. The Amg, which receives input from brain areas encoding internal states, innately relevant stimuli, and innately neutral stimuli, plays a fundamental role in the motivational and emotional processes of organisms. This role is based on the fact that Amg implements the two associative processes at the core of Pavlovian learning (conditioned stimulus (CS)-unconditioned stimulus (US) and CS-unconditioned response (UR) associations), and that it has the capacity of modulating these associations on the basis of internal states. These functionalities allow the Amg to play an important role in the regulation of the three fundamental classes of affective responses (namely, the regulation of body states, the regulation of brain states via neuromodulators, and the triggering of a number of basic behaviours fundamental for adaptation) and in the regulation of three high-level cognitive processes (namely, the affective labelling of memories, the production of goal-directed behaviours, and the performance of planning and complex decision-making). Our analysis is conducted within a methodological approach that stresses the importance of understanding the brain within an evolutionary/adaptive framework and with the aim of isolating general principles that can potentially account for the wider possible empirical evidence in a coherent fashion.

    Whole-body computed tomography (CT) image registration is important for cancer diagnosis, therapy planning and treatment. Such registration requires accounting for large differences between source and target images caused by deformations of soft organs/tissues and articulated motion of skeletal structures. The registration algorithms relying solely on image processing methods exhibit deficiencies in accounting for such deformations and motion. We propose to predict the deformations and movements of body organs/tissues and skeletal structures for whole-body CT image registration using patient-specific non-linear biomechanical modelling. Unlike the conventional biomechanical modelling, our approach for building the biomechanical models does not require time-consuming segmentation of CT scans to divide the whole body into non-overlapping constituents with different material properties. Instead, a Fuzzy C-Means (FCM) algorithm is used for tissue classification to assign the constitutive properties automatically at integration points of the computation grid. We use only very simple segmentation of the spine when determining vertebrae displacements to define loading for biomechanical models. We demonstrate the feasibility and accuracy of our approach on CT images of seven patients suffering from cancer and aortic disease. The results confirm that accurate whole-body CT image registration can be achieved using a patient-specific non-linear biomechanical model constructed without time-consuming segmentation of the whole-body images.

  11. Interactions of bluff-body obstacles with turbulent airflows affecting evaporative fluxes from porous surfaces

    Bluff-body obstacles interacting with turbulent airflows are common in many natural and engineering applications (from desert pavement and shrubs over natural surfaces to cylindrical elements in compact heat exchangers). Even with obstacles of simple geometry, their interactions within turbulent airflows result in a complex and unsteady flow field that affects surface drag partitioning and transport of scalars from adjacent evaporating surfaces. Observations of spatio-temporal thermal patterns on evaporating porous surfaces adjacent to bluff-body obstacles depict well-defined and persistent zonation of evaporation rates that were used to construct a simple mechanistic model for surface-turbulence interactions. Results from evaporative drying of sand surfaces with isolated cylindrical elements (bluff bodies) subjected to constant turbulent airflows were in good agreement with model predictions for localized exchange rates. Experimental and theoretical results show persistent enhancement of evaporative fluxes from bluff-rough surfaces relative to smooth flat surfaces under similar conditions. The enhancement is attributed to formation of vortices that induce a thinner boundary layer over part of the interacting surface footprint. For a practical range of air velocities (0.5-4.0 m/s), low-aspect ratio cylindrical bluff elements placed on evaporating sand surfaces enhanced evaporative mass losses (relative to a flat surface) by up to 300% for high density of elements and high wind velocity, similar to observations reported in the literature. Concepts from drag partitioning were used to generalize the model and upscale predictions to evaporation from surfaces with multiple obstacles for potential applications to natural bluff-rough surfaces.

    This study looks into the rigid-body registration of pre-operative anatomical high field and interventional low field magnetic resonance images (MRI). The accurate 3D registration of these modalities is required to enhance the content of interventional images with anatomical (CT, high field MRI, DTI), functional (DWI, fMRI, PWI), metabolic (PET) or angiography (CTA, MRA) pre-operative images. The specific design of the interventional MRI scanner used in the present study, a PoleStar N20, induces image artifacts, such as ellipsoidal masking and intensity inhomogeneities, which affect registration performance. On MRI data from eleven patients, who underwent resection of a brain tumor, we quantitatively evaluated the effects of artifacts in the image registration process based on a normalized mutual information (NMI) metric criterion. The results show that the quality of alignment of pre-operative anatomical and interventional images strongly depends on pre-processing carried out prior to registration. The registration results scored the highest in visual evaluation only if intensity variations and masking were considered in image registration. We conclude that the alignment of anatomical high field MRI and PoleStar interventional images is the most accurate when the PoleStar's induced image artifacts are corrected for before registration.

  13. Studies on wake-affected heat transfer around the circular leading edge of blunt body

    Detailed measurements are performed about time-averaged heat transfer distributions around the leading edge of a blunt body, which is affected by incoming periodic wakes from the upstream moving bars. The blunt body is a test model of a front portion of a turbine blade in gas turbines and consists of a semicircular cylindrical leading edge and a flat plate afterbody. A wide range of the steady and unsteady flow conditions are adopted as for the Reynolds number based on the diameter of the leading edge and the bar-passing Strouhal number. The measured heat transfer distributions indicate that the wakes passing over the leading edge cause a significant increase in heat transfer before the separation and the higher Strouhal number results in higher heat transfer. From this experiment, a correlation for the heat transfer enhancement around the leading edge due to the periodic wakes is deduced as a function of the Stanton number and it is reviewed by comparison with the other experimental works.

    Understanding how animals react to human-induced changes in their environment is a key question in conservation biology. Owing to their potential correlation with fitness, several physiological parameters are commonly used to assess the effect of habitat disturbance on animals' general health status. Here, we studied how two lemur species, the fat-tailed dwarf lemur (Cheirogaleus medius) and the grey mouse lemur (Microcebus murinus), respond to changing environmental conditions by comparing their stress levels (measured as hair cortisol concentration), parasitism and general body condition across four habitats ordered along a gradient of human disturbance at Kirindy Forest, Western Madagascar. These two species previously revealed contrasting responses to human disturbance; whereas M. murinus is known as a resilient species, C. medius is rarely encountered in highly disturbed habitats. However, neither hair cortisol concentrations nor parasitism patterns (prevalence, parasite species richness and rate of multiple infections) and body condition varied across the gradient of anthropogenic disturbance. Our results indicate that the effect of anthropogenic activities at Kirindy Forest is not reflected in the general health status of both species, which may have developed a range of behavioural adaptations to deal with suboptimal conditions. Nonetheless, a difference in relative density among sites suggests that the carrying capacity of disturbed habitat is lower, and both species respond differently to environmental changes, with C. medius being more negatively affected. Thus, even for behaviourally flexible species, extended habitat deterioration could hamper long-term viability of populations. PMID:27656285

    Whole-body molecular imaging is able to directly map spatial distribution of molecules and monitor its biotransformation in intact biological tissue sections. Imaging mass spectrometry (IMS), a label-free molecular imaging method, can be used to image multiple molecules in a single measurement with high specificity. Herein, a novel easy-to-implement, whole-body IMS method was developed with air flow-assisted ionization in a desorption electrospray ionization mode. The developed IMS method can effectively image molecules in a large whole-body section in open air without sample pretreatment, such as chemical labeling, section division, or matrix deposition. Moreover, the signal levels were improved, and the spatial assignment errors were eliminated; thus, high-quality whole-body images were obtained. With this novel IMS method, in situ mapping analysis of molecules was performed in adult rat sections with picomolar sensitivity under ambient conditions, and the dynamic information of molecule distribution and its biotransformation was provided to uncover molecular events at the whole-animal level. A global view of the differential distribution of an anticancer agent and its metabolites was simultaneously acquired in whole-body rat and model mouse bearing neuroglioma along the administration time. The obtained drug distribution provided rich information for identifying the targeted organs and predicting possible tumor spectrum, pharmacological activity, and potential toxicity of drug candidates.

    The fibrils that yielded the Shroud body image show a stochastic distribution on the Linen of Turin. In fact, the probability of a fibril yellowing is a function of the energy, while this is not the case for the optical density value. This means that the above image is a latent image. We suggest thermal radiation or low-temperature chemical processes as possible natural energy sources to explain, by stochastic effects, the Shroud body image formation. Unfortunately, due to the nature of the phenomenon, we are not able to extract the energy source.

    A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed.

    2014-01-01

    This study aimed to investigate the effect of 'retouch free' labels on thin ideal fashion images on women's body dissatisfaction. This represents an experimental analogue to current practice by some fashion magazines. Participants were 224 female undergraduates who viewed a set of fashion shoots with either no label, or a label indicating that the image had not been digitally altered. Results indicated that, although body dissatisfaction increased after exposure to the thin ideal images, there was no significant effect of label type on mood or body dissatisfaction. It was concluded that labelling images as digitally unaltered appears neither helpful nor harmful in terms of body dissatisfaction. Nevertheless, more extensive research is required to guide the most effective use of labels.

    The current study examines the role of self-compassion in face of shame and body image dissatisfaction, in 102 female eating disorders' patients, and 123 women from general population. Self-compassion was negatively associated with external shame, general psychopathology, and eating disorders' symptomatology. In women from the general population increased external shame predicted drive for thinness partially through lower self-compassion; also, body image dissatisfaction directly predicted drive for thinness. However, in the patients' sample increased shame and body image dissatisfaction predicted increased drive for thinness through decreased self-compassion. These results highlight the importance of the affiliative emotion dimensions of self-compassion in face of external shame, body image dissatisfaction and drive for thinness, emphasising the relevance of cultivating a self-compassionate relationship in eating disorders' patients.

  2. Contact-free determination of human body segment parameters by means of videometric image processing of an anthropomorphic body model

    1993-01-01

    The development of noninvasive techniques for the determination of biomechanical body segment parameters (volumes, masses, the three principal moments of inertia, the three local coordinates of the segmental mass centers, etc.) receives increasing attention from the medical sciences (e,.g., orthopaedic gait analysis), bioengineering, sport biomechanics, and the various space programs. In the present paper, a novel method is presented for determining body segment parameters rapidly and accurately. It is based on the video-image processing of four different body configurations and a finite mass-element human body model. The four video images of the subject in question are recorded against a black background, thus permitting the application of shape recognition procedures incorporating edge detection and calibration algorithms. In this way, a total of 181 object space dimensions of the subject's body segments can be reconstructed and used as anthropometric input data for the mathematical finite mass- element body model. The latter comprises 17 segments (abdomino-thoracic, head-neck, shoulders, upper arms, forearms, hands, abdomino-pelvic, thighs, lower legs, feet) and enables the user to compute all the required segment parameters for each of the 17 segments by means of the associated computer program. The hardware requirements are an IBM- compatible PC (1 MB memory) operating under MS-DOS or PC-DOS (Version 3.1 onwards) and incorporating a VGA-board with a feature connector for connecting it to a super video windows framegrabber board for which there must be available a 16-bit large slot. In addition, a VGA-monitor (50 - 70 Hz, horizontal scan rate at least 31.5 kHz), a common video camera and recorder, and a simple rectangular calibration frame are required. The advantage of the new method lies in its ease of application, its comparatively high accuracy, and in the rapid availability of the body segment parameters, which is particularly useful in clinical practice

    Background: Unpleasant attention to unfavorable fat may have harmful psychological effects in terms of body dissatisfaction. As a consequence, this may cause abnormal eating regulation. It has been noted that women interested in liposuction self-report more eating problems. As far as we know, there are no prospective studies with standardized instruments providing sufficient data regarding the effects of aesthetic liposuction on various aspects of quality of life. Nevertheless, publications on the effects of eating habits are lacking. Methods: Sixty-one consecutive women underwent aesthetic liposuction. Three outcome measures were applied at baseline and at follow-up: the eating disorder inventory, Raitasalo's modification of the Beck depression inventory, and the 15-dimensional general quality of life questionnaire. Results: The mean age at baseline was 44 years, and the mean body mass index was 26.0. Thirty-six (59%) women completed all outcome measures with a mean follow-up time of 7 months. A significant improvement from baseline to follow-up was noted in women's body satisfaction, and their overall risk for developing an eating disorder decreased significantly. Conclusion: Aesthetic liposuction results in a significantly reduced overall risk for an eating disorder in combination with improved body satisfaction. PMID:26301150

    Conclusion The antero-posterior (AP) body tracking test (BTT) showed that the dominant foot could affect the tilt angle of the sway movement, delineated by primary component analysis. Differences associated with the dominant foot could represent the difference in space perception of each person. Objectives To examine whether the dominant foot could affect the postural control mechanism using the BTT. Methods Ninety-seven healthy participants enrolled in the study were classified into right-foot and left-foot dominance groups, and their performances were compared. For the BTT, each participant stood on a stabilometer and caught the movement of a visual target moving vertically (anterior-posterior) or horizontally by the center of pressure movement, displayed on a 14-inch screen monitor at 100 cm in front of the subject. The mean displacement angle of the obtained stabilogram was evaluated by principal component analysis. Results The AP BTT in the right-foot dominance group showed a clockwise tilt with a mean displacement angle of 3.022 ± 3.761°, whereas the group with left-foot dominance had a modest counter-clockwise tilt with a mean displacement angle of –0.694 ± 4.497°. This difference was found to be significant by the independent t test (p < 0.0001). In the lateral BTT, the mean displacement angles were not significant. PMID:25252704

    Objective Body image disturbance is a common experience for sexual minority men living with HIV, and is associated with poor self-care behaviors. However, to date, no known cohesive theoretical model has been advanced to understand the possible antecedents and outcomes of body image disturbance in this population. Thus, the goal of the current study was to test a biopsychosocial model of body image and self-care behaviors among sexual minority men living with HIV. Methods Participants were 106 gay and bisexual men living with HIV who completed a battery of self-report measures including assessment of body image disturbance, depression, lipodystrophy, appearance orientation, condom use self-efficacy, antiretroviral therapy (ART) adherence, and HIV sexual transmission risk behaviors. Bayesian estimation was employed to assess model fit and direct and indirect pathways within the model. Results The data fit the model well, with all theorized pathways being significant. Lipodystrophy severity and appearance orientation were associated with elevated body image disturbance. In turn, body image disturbance was related to poorer ART adherence and increased HIV sexual transmission risk behaviors, through the mechanisms of elevated depressive symptoms and poor condom use self-efficacy. Conclusions Elevated body image disturbance among sexual minority men living with HIV is associated with important biopsychosocial variables, which in turn are related to poorer ART adherence and increased HIV sexual transmission risk behaviors. Integrative psychosocial interventions addressing co-occurring body image disturbance, depression, and HIV self-care behaviors may be a fruitful area of future clinical practice and research.

    Purpose The purpose of this study is to examine the relationship between body image and depressive symptoms in patients who have been treated for head and neck cancer. Methods This is a prospective, longitudinal analysis. Body image and depressive symptoms were measured in patients diagnosed with head and neck cancer at baseline, end of treatment, 6 weeks post-treatment, and 12 weeks post-treatment. Body image was measured using the Body Image Quality of Life Inventory, and depressive symptoms were measured using the Center for Epidemiological Studies Depression Scale. Results Forty-three individuals diagnosed with head and neck cancer participated in this study. The majority of participants were male, Caucasian, and married or living with a partner. Participants ranged from age 32 to 78 years (M=57.8 years, SD=10.5 years). At 12 weeks post-treatment, body image scores were statistically significantly higher than they were at the end of treatment (p=0.016) and 6 weeks post-treatment (p=0.032). Statistically significant increases in levels of depressive symptoms were observed at the end of treatment (p<0.001) and 6 weeks post-treatment (p=0.036) with a return to baseline by the 12-week post-treatment assessment (p=0.115). Body image and depressive symptoms were statistically significantly associated at the end of treatment, 6 weeks post-treatment, and 12 weeks post-treatment (rs −0.32 to −0.56, p <0.05). Conclusions This study supports early assessment of body image in patients with head and neck cancer. Additionally, the association between poorer body image and increased depressive symptoms is key in understanding the symptom clusters that patients with head and neck cancer experience.

    A method is developed for online monitoring of structural and morphological parameters of biological tissues (haemoglobin concentration, degree of blood oxygenation, average diameter of capillaries and the parameter characterising the average size of tissue scatterers), which involves multispectral tissue imaging, image normalisation to one of its spectral layers and determination of unknown parameters based on their stable regression relation with the spectral characteristics of the normalised image. Regression is obtained by simulating numerically the diffuse reflectance spectrum of the tissue by the Monte Carlo method at a wide variation of model parameters. The correctness of the model calculations is confirmed by the good agreement with the experimental data. The error of the method is estimated under conditions of general variability of structural and morphological parameters of the tissue. The method developed is compared with the traditional methods of interpretation of multispectral images of biological tissues, based on the solution of the inverse problem for each pixel of the image in the approximation of different analytical models.

    The zebrafish, an ideal vertebrate for studying developmental biology and genetics, is increasingly being used to understand human diseases, due to its high similarity to the human genome and its optical transparency during embryonic stages. Once the zebrafish has fully developed, especially wild-type breeds, conventional optical imaging techniques have difficulty in imaging the internal organs and structures with sufficient resolution and penetration depth. Even with established mutant lines that remain transparent throughout their life cycle, it is still challenging for purely optical imaging modalities to visualize the organs of juvenile and adult zebrafish at a micro-scale spatial resolution. In this work, we developed a non-invasive three-dimensional photoacoustic imaging platform with an optimized illumination pattern and a cylindrical-scanning-based data collection system to image entire zebrafish with micro-scale resolutions of 80 μm and 600 μm in the lateral and axial directions, respectively. In addition, we employed a multispectral strategy that utilized excitation wavelengths from 690 nm to 930 nm to statistically quantify the relative optical absorption spectrum of major organs.

    This study examined whether the association between adolescent weight status and body image varies by social engagement. A nationally representative sample of 6909 students in grades 6-10 completed the 2006 HBSC survey. Separate linear regressions for boys and girls, controlling for age, race/ethnicity and socioeconomic status, were conducted with an interaction term (weight status×social engagement). Adolescents' overweight/obese status was related to body dissatisfaction. Social engagement moderated the relationship between weight status and body image for girls but not for boys. Overweight/obese boys had more body dissatisfaction compared to their normal/underweight peers, regardless of their social engagement. However, overweight/obese girls with more social engagement were more likely to have body satisfaction compared to overweight/obese girls with less social engagement. Encouraging adolescent girls to develop healthy relationships with peers may prevent them from developing body dissatisfaction.

    Differentiation between adenomyomatosis (ADM) and cancer of the gallbladder is necessary during diagnosis. Diffusion-weighted whole body imaging with background body signal suppression (DWIBS) images are able to indicate cancer and inflammation. The fusion of a DWIBS with a T2 weighted image (DWIBS/T2) facilitates both functional and anatomical investigations. In the present study, patient records and images from patients with surgically confirmed ADM from April 2012 to October 2014 were analyzed retrospectively. The enrolled patients, including 6 men (64.2±13.1 years) and 4 women (57.3±12.4 years) were subjected to DWIBS/T2 during routine clinical practice. The diagnosis of ADM was based on magnetic resonance cholangiopancreatography, transabdominal ultrasonography, and endoscopic ultrasonography; ADM was diagnosed definitively when cystic lesions were observed, indicating the Rokitansky-Aschoff sinus. A single patient was indicated to be positive by DWIBS/T2 imaging. The Rokitansky-Aschoff sinus revealed a relatively high signal intensity; however, it was not as strong as that of the spleen. The signal intensity was also high on an apparent diffusion coefficient map, suggesting T2 shine-through. The thickened wall displayed low signal intensity. The aforementioned results indicate that ADM may be negative upon DWIBS/T2 imaging; one false positive case was determined to be ADM, accompanied by chronic cholecystitis. The majority of patients with ADM displayed negative findings upon DWIBS/T2 imaging, and chronic cholecystitis may cause false positives. PMID:27168802

    Traditionally, body image literature has used race as a variable to explain ethnic-specific differences in body satisfaction and the prevalence of eating disorders. Instead of employing race as an explanatory variable, the present study utilized a qualitative method to explore the relationships among race, ethnicity, culture, discrimination, and body image for African American and Black women. The purpose of the study was to gain a deeper understanding of how race and gender interface with and inform body image. Women were recruited through community centers in a major metropolitan city and represented a diversity of ethnicities. In total, 26 women who identified racially as Black (mean age = 26 years) participated in 6 focus groups, which explored body ideals, societal messages, cultural values, racism, and sexism. Narrative data from the focus groups were analyzed using grounded theory. The central category, Body/Self Image, was informed by perceptions of and feelings about not only weight and shape but also hair, skin, and attitude. Three additional categories, each with multiple properties, emerged: Interpersonal Influences, Experiences of Oppression, and Media Messages. These categories interact to explain the central category of Body/Self Image, and an emergent theory is presented. (PsycINFO Database Record (c) 2014 APA, all rights reserved). PMID:24188651
