    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.

    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.

  4. 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.

    Previous body image research suggests that first, exposure to body stimuli can negatively affect men's body satisfaction and second, body concerns are associated with dysfunctional gaze behavior. To date, however, the effects of self- vs. other-referential body stimuli and of gaze behavior on body image in men under exposure conditions have not been investigated. Therefore, 49 weight-trained men were presented with pictures of their own and other bodies of different builds (i.e., normal, muscular, hyper-muscular) while being eye-tracked. Participants completed pre- and post-exposure measures of body image and affect. Results indicated that one's own and the muscular body negatively affected men's body image to a comparable degree. Exposure to one's own body also led to increased negative affect. Increased attention toward disliked own body parts was associated with a more negative post-exposure body image and affect. These results suggest a crucial role of critical self-examination in maintaining body dissatisfaction.

    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. In this photograph, a patient undergoes an open MRI.

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

    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

    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.

    2014-01-01

    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.

    Body motion is a rich source of information for social cognition. However, gender effects in body language reading are largely unknown. Here we investigated whether, and, if so, how recognition of emotional expressions revealed by body motion is gender dependent. To this end, females and males were presented with point-light displays portraying knocking at a door performed with different emotional expressions. The findings show that gender affects accuracy rather than speed of body language reading. This effect, however, is modulated by emotional content of actions: males surpass in recognition accuracy of happy actions, whereas females tend to excel in recognition of hostile angry knocking. Advantage of women in recognition accuracy of neutral actions suggests that females are better tuned to the lack of emotional content in body actions. The study provides novel insights into understanding of gender effects in body language reading, and helps to shed light on gender vulnerability to neuropsychiatric and neurodevelopmental impairments in visual social cognition.

  1. Body Image and Body Contouring Procedures.

    PubMed

    Sarwer, David B; Polonsky, Heather M

    2016-10-01

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

    2016-03-01

    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.

    2006-02-01

    Researchers have highlighted the significance of a poor body image in the development of dysfunctional eating but have systematically investigated few other outcomes. The authors examined the relationships between different aspects of body image and psychosocial functioning. Participants were 245 boys and 173 girls from Grades 8 and 9 (M age = 13.92 years, SD = 0.69 years). Respondents completed measures of physical attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and same-sex and opposite-sex relations. Whereas girls tended to report a more negative body image than did boys, the relevance of body image to self-esteem was similar for boys and girls. Concern about others' evaluation of their bodies was especially important in understanding low female self-esteem, whereas for boys, ratings of general attractiveness most strongly predicted self-esteem. The authors found a negative body image to be unrelated to symptoms of negative affect but to be strongly associated with poor opposite-sex peer relationships, especially among boys. A negative body image also affected same-sex relations among girls.

  8. Implicit beliefs about ideal body image predict body image dissatisfaction

    2015-01-01

    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.

    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.

  11. [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.

  13. Body image concerns after colorectal cancer surgery.

    PubMed

    Taylor, Claire

    Body image is understood to be a person's perception of his or her own physical appearance although, as this article highlights, it embraces a greater range of bodily attributes than is often appreciated. It can be significantly affected by a diagnosis of colorectal cancer and subsequent treatment, which may modify the way the body looks, feels and functions. One of the major aesthetic and functional consequences of colorectal cancer surgery is the possibility of stoma formation, which is of particular concern to many. However, the range of other bodily effects following surgery should not be overlooked, not least because of they may result in distress. While concerns about changes in body image generally decrease over time, people recovering from cancer treatment often feel their relationship with their body has been permanently altered. Specialist support is often required when adjusting to any changes in bodily appearance and function. Care outcomes can be improved by having a sound understanding of the body image concerns likely to arise following treatment, as well as the skills to identify and support patients at risk of altered body image. This article provides guidance to nurses caring for individuals who may be experiencing distress over how their body is now perceived by themselves and others following colorectal cancer surgery.

    Two studies examine qualities capturing adolescents' images of ideal bodies for both genders. Data from questionnaires and discussions of photographs indicate that body-image ideals are multidimensional, show systematic gender differences, and become more conventional with age. Adolescents' own body mass links systematically to body-image…

    Although obesity is associated with osteoarthritis, it is unclear whether body weight (BW) independently affects articular cartilage catabolism (i.e., independent from physiological factors that also accompany obesity). The primary purpose of this study was to evaluate the independent effect of BW on articular cartilage catabolism associated with walking. A secondary purpose was to determine how decreased BW influenced cardiovascular response due to walking. Twelve able-bodied subjects walked for 30 minutes on a lower-body positive pressure treadmill during three sessions: control (unadjusted BW), +40%BW, and -40%BW. Serum cartilage oligomeric matrix protein (COMP) was measured immediately before (baseline) and after, and 15 and 30 minutes after the walk. Heart rate (HR) and rate of perceived exertion (RPE) were measured every three minutes during the walk. Relative to baseline, average serum COMP concentration was 13% and 5% greater immediately after and 15 minutes after the walk. Immediately after the walk, serum COMP concentration was 14% greater for the +40%BW session than for the -40%BW session. HR and RPE were greater for the +40%BW session than for the other two sessions, but did not differ between the control and -40%BW sessions. BW independently influences acute articular cartilage catabolism and cardiovascular response due to walking: as BW increases, so does acute articular cartilage catabolism and cardiovascular response. These results indicate that lower-body positive pressure walking may benefit certain individuals by reducing acute articular cartilage catabolism, due to walking, while maintaining cardiovascular response. Key points Walking for 30 minutes with adjustments in body weight (normal body weight, +40% and -40% body weight) significantly influences articular cartilage catabolism, measured via serum COMP concentration. Compared to baseline levels, walking with +40% body weight and normal body weight both elicited significant increases in

    Although some research has shown that dance enhances body image and self-esteem, other research shows that it sometimes has the opposite effect and causes dancers to develop a negative body image and even eating disorders. In dance, body image is not only about maintaining a certain weight; it can also refer to specific perceived body flaws.…

  17. Mindfulness, body image, and drive for muscularity in men.

    PubMed

    Lavender, Jason M; Gratz, Kim L; Anderson, Drew A

    2012-03-01

    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.

    2016-08-01

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

    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

    2015-03-01

    Men generally have a more positive body image than women. However, the extent to which scars negatively influence men's body image is uncertain. The aim of the current study was to assess body image in men with and without scars while taking scar origin into account (nonsuicidal self-harming injuries [NSSI] vs. accidents or surgery). One hundred and nine men (n = 19 with NSSI) and 185 women (n = 96 with NSSI) filled in multidimensional body image questionnaires. Results indicate that on most clinical subscales women had a significantly more negative body image compared with men. However, within a subsample whose scars resulted from NSSI, gender differences vanished. Among men, scar origin was significantly associated with negative body image after partialling out scar characteristics, age, and borderline symptomatology. The visibility of scars was not associated with more severe body image disturbances. The results of our study indicate that self-inflicted scars adversely affect body image. Although women generally reported having a more negative body image, disturbances in body image should not be neglected among men, especially in those who have self-inflicted scars.

    2013-07-01

    Chronic diseases pose a major challenge to contemporary western healthcare systems, and consequently there are numerous initiatives designed to meet these challenges. Patient empowerment is considered to be extremely important in chronic disease management. But what does it mean to become an 'active patient', managing a condition? This article argues that people are always active in shaping their agency and the agency of numerous others, and that we need to attend to these processes of configuration in order to better understand and conceptualize the problem of chronic disease management. This article analyses the daily practices of people with Type 2 Diabetes, with the use of what is described as the 'sociology of attachment' in the field of science and technology studies. The implications of seeing and analysing chronic conditions in this manner are that determinist understandings of chronic conditions are challenged. Accordingly, an experimental and constructive attitude towards the production and assembling of the chronically ill body is enabled. Such an attitude holds that relations with multiple other bodies and entities, such as technologies, the disease, medication and so on continuously and relentlessly affect how the condition unfolds and consequently, the room for interventional strategies and transformation of the chronically ill body is enlarged.

    Borzekowski, Dina L G; Bayer, Angela M

    2005-06-01

    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.

    2015-06-01

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

    2016-12-01

    This study systematically reviewed the evidence for personality as a correlate of body image. Electronic databases and reference lists were searched in May 2016 for studies reporting an association between at least one dimension of personality and at least one component of negative body image. Twenty-six studies (33 discrete samples) met inclusion criteria. Sixteen samples were coded as medium-high quality. The results indicated that negative body image was associated with higher levels of Neuroticism and lower levels of Extraversion. Agreeableness was not related to body image, and findings for Conscientiousness and Openness were indeterminate. After taking study quality into account, negative body image was also associated with lower levels of Conscientiousness. Neuroticism was associated with negative body image in both women and men. Sex moderation effects for Extraversion, Openness, and Conscientiousness were indeterminate. Large-sample, prospective studies of personality and body image are recommended.

    This research used ecological momentary assessment to examine the effects of exercise on state body dissatisfaction and affect in 33 undergraduate females with high trait body dissatisfaction and 28 with low trait body dissatisfaction who exercised at least three times weekly. Trait body dissatisfaction was investigated as a moderator of the effects of exercise as well as different motivations for exercise. Results indicated all participants experienced lower state body dissatisfaction and negative affect and greater positive affect post-exercise. Trait body dissatisfaction moderated the association between motivations and exercise effects. Appearance and weight motivations were related to higher state body dissatisfaction for all individuals. Fitness and health motivations were related to higher state body dissatisfaction for high trait body dissatisfied individuals and lower state body dissatisfaction for low trait body dissatisfied individuals. Thus, although exercise has positive effects on body dissatisfaction and affect for high frequency exercisers, their exercise motivations impact these effects.

    Adolescent stress is clearly implicated in the development of mental health problems. However, its role in dysfunctional body image, which rises markedly in adolescence, has not been investigated. The present study examined the link between stress and body image, as well as self-esteem and depressive symptoms, in 533 high school students in grades 7 to 10. Results indicated that stress accounts for a sizeable proportion of variance in body image, and the best exploratory model included stress, self-esteem, and gender. Further, specific domains of stressors related to body image differently: peer pressure and school attendance were significant correlates of body image in both genders, while future uncertainty and romantic relationships were significant for males alone. Grade differences in primary variables were also evident for females. This study helps to elucidate the role of adolescent stress in dysfunctional body image and provides insight for future prevention and intervention programs in schools.

    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

  11. Body image distortions in healthy adults.

    Fuentes, Christina T; Longo, Matthew R; Haggard, Patrick

    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.

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

    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.

    2016-09-01

    Magnetic resonance imaging (MRI) is a radiation-free imaging modality with excellent contrast resolution and multiplanar capabilities. Since ionizing radiation is an important concern in the pediatric population, MRI serves as a useful alternative to computed tomography (CT) and also provides additional clues to diagnosis, not discernible on other investigations. Magnetic resonance cholangiopancreatography (MRCP), urography, angiography, enterography, dynamic multiphasic imaging and diffusion-weighted imaging provide wealth of information. The main limitations include, long scan time, need for sedation/anesthesia, cost and lack of widespread availability. With the emergence of newer sequences and variety of contrast agents, MRI has become a robust modality and may serve as a one-stop shop for both anatomical and functional information.

  19. Low temperature alteration processes affecting ultramafic bodies

    1978-01-01

    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.

    2015-03-30

    Body image disturbance and body dysmorphic disorder (BDD) have been researched from a variety of psychological approaches. Psychological inflexibility, or avoidance of one's own cognitive and affective states at a cost to personal values, may be a useful construct to understand these problems. In an effort to clarify the role of psychological inflexibility in body image disturbance and BDD, a measure was created based on the principles of Acceptance and Commitment Therapy (ACT). The scale was developed by generating new items to represent the construct and revising items from an existing scale measuring aspects of body image psychological inflexibility. The study was conducted with an ethnically diverse undergraduate population using three samples during the validation process. Participants completed multiple assessments to determine the validity of the measure and were interviewed for BDD. The 16-item scale has internal consistency (α = 0.93), a single factor solution, convergent validity, and test re-test reliability (r = 0.90). Data demonstrate a relationship between psychological inflexibility and body image disturbance indicating empirical support for an ACT conceptualization of body image problems and the use of this measure for body image disturbance and BDD.

  5. Does affective touch influence the virtual reality full body illusion?

    PubMed

    de Jong, Jutta R; Keizer, Anouk; Engel, Manja M; Dijkerman, H Chris

    2017-03-13

    The sense of how we experience our physical body as our own represents a fundamental component of human self-awareness. Body ownership can be studied with bodily illusions which are generated by inducing a visuo-tactile conflict where individuals experience illusionary ownership over a fake body or body part, such as a rubber hand. Previous studies showed that different types of touch modulate the strength of experienced ownership over a rubber hand. Specifically, participants experienced more ownership after the rubber hand illusion was induced through affective touch vs non-affective touch. It is, however, unclear whether this effect would also occur for an entire fake body. The aim of this study was, therefore, to investigate whether affective touch modulates the strength of ownership in a virtual reality full body illusion. To elicit this illusion, we used slow (3 cm/s; affective touch) and fast (30 cm/s; non-affective touch) stroking velocities on the participants' abdomen. Both stroking velocities were performed either synchronous or asynchronous (control condition), while participants viewed a virtual body from a first-person-perspective. In our first study, we found that participants experienced more subjective ownership over a virtual body in the affective touch condition, compared to the non-affective touch condition. In our second study, we found higher levels of subjective ownership for synchronous stimulation, compared to asynchronous, for both touch conditions, but failed to replicate the findings from study 1 that show a difference between affective and non-affective touch. We, therefore, cannot conclude unequivocally that affective touch enhances the full-body illusion. Future research is required to study the effects of affective touch on body ownership.

    2003-01-01

    Objective: To compare cardiovascular and ventilatory variables in upright versus aero cycle ergometry at submaximal and maximal exercise intensities in untrained cyclists. Method: Ten physically active men (mean (SD) age 19.1 (1.10) years) who were unfamiliar with aerobars underwent maximal exercise testing and steady state cycling at 50, 100, and 150 W. Results: Participants had significantly greater maxima for oxygen uptake (VO2), ventilation, heart rate, and workload maximum in the upright position. During steady state cycling at the three workloads, VO2 (ml/kg/min) and gross mechanical efficiency were significantly greater in the upright position. Conclusions: In untrained subjects performing with maximal effort, the upright position permits greater VO2, ventilation, heart rate, and workload maxima. Further, in the steady state, exercise cycling may be less costly in the upright position. For this reason, untrained cyclists need to weigh body position effects against the well known aerodynamic advantages of the aero position. PMID:14514538

    2009-08-01

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

  8. Imaging of drug smuggling by body packing.

    Body packing, pushing, and stuffing are hazardous practices with complex medicolegal and social implications. A radiologist plays both a social and a medicolegal 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 so as to prevent any package remains in the body packer. Radiologists must also be able to recognize the complications associated with these risky practices. Imaging assessment of body packing is performed essentially through plain abdominal X-ray and computed tomography scans. Ultrasound and magnetic resonance imaging, although with some advantages, actually have a limited use.

    The purpose of this study was to investigate body image concerns and psycho-emotional health in males with acquired brain injury (ABI). Using a between subjects study of 25 males with ABI and 25 matched controls, variables were analysed using correlations and 2 x 2 analyses of variance (ANOVAs) with head injury and injury type as independent variables. Body image and psycho-emotional health were evaluated using self-report questionnaires. Disability and cognitive impairment were measured using a mixture of self-report, cognitive testing and clinical notes. Results indicated that males with ABI had significantly lower self-esteem and body dissatisfaction on a number of items relating to physical and sexual functioning. There were significant differences in body image between stroke and TBI, but there was no corresponding relationship with psycho-emotional health. These body image differences might be explained by age. The finding that ABI has a negative effect on body image and that this relates to psycho-emotional health should be investigated further, perhaps being included in future rehabilitation strategies.

    The study examines the impact of body image in adolescents' well-being. Well-being was assessed with the scale Kidscreen10, with the Cantril ladder for satisfaction with life and with an ad hoc happiness scale. The study presents data on adolescent health from the Health Behavior in School-aged Children (HBSC)/World Health Organization study in Portugal (2006), with a sample of 4,877 adolescents, average age of 14 years old and gender distribution at 49,6% males. Portuguese adolescents showed differences between gender and age group regarding their body image-related satisfaction/dissatisfaction and self-perceived body image, being that both components have a direct impact on the levels of well-being. The male gender has better results in the perception of body image and, consequently, well-being. The largest inter-gender differences for well-being is at 15 years of age. The main predictors of well-being are the look and body satisfaction/dissatisfaction, with greater importance on the affective component. This research highlights the importance of body image for adolescents' well-being, as well as to prepare educational strategies adapted to adolescents' age and gender, by helping them to develop skills concerning self-knowledge and caring for their look.

    This study looks at body image disturbance among Jamaicans who bleach their skin. The hypothesis states that there is a positive relationship between skin bleaching and body image disturbance. The study used a convenience sample of 160 participants with a skin bleaching group (n = 80) and a non-bleaching comparison group (n = 80). The instrument included demographic questions, the body image disturbance questionnaire (BIDQ), and questions about skin bleaching. The results of a t-test revealed that the skin bleaching group (M = 1.5255, SD = 0.42169) was not significantly different from the non-bleaching group (M = 1.4938, SD = 0.74217) in terms of body image disturbance, t(158) = 0.333, p = .740. The participants who bleached did not suffer from body image disturbance. Self-reports revealed that they bleached to acquire beauty, attract a partner, elude the police, and market skin bleaching products. The practice was fashionable and popular and it made some participants feel good, while others were fans of a popular musical artiste who bleached his skin. The majority of participants bleached because of the perceived personal, social, and entrepreneurial benefits of the practice and not because they suffered emotional distress, anxiety, and functional impairment because of their skin colour. However, there was some level of BID among the minority of participants who argued that they bleached because they wanted to be pretty so they were emotionally distressed about there body image and experienced functional impairment.

    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

    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.

  15. Enabling patients to manage altered body image.

    2016-12-14

    The author presented a model in the 1990s to explain altered body image, which has been used to characterise the difficulties encountered by patients who experience body change as a result of illness, injury or disability. However, it remains a challenge for nurses to establish care plans that can assist patients to manage the psychological adjustments associated with disfigurement. This article presents some simple questions to help patients narrate their psychological experiences and needs, and proposes a model of psychological change, based on the work of Kübler-Ross, to enable nurses to anticipate patient requirements that might arise at different stages of the individual's recovery and rehabilitation. Body-image rehabilitation may be protracted. Therefore, it is essential for nurses to understand what the patient is thinking and feeling throughout the rehabilitation process and which stage of psychological change the patient is working through.

    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.

    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.

    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

    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.

    2000-01-01

    Based on interviews conducted with eight lesbians, this paper explores how the intersection of gender, sexual identity, race, ethnicity, and class affect lesbians' feelings about their bodies. Their responses suggest that, while being female has a strong effect on lesbians' feelings about their bodies, issues of race, acculturation, and class also affect body image. Lesbian feminism and S/M politics also appear to play a significant role in lesbians' body image. These findings highlight the limitations of existing theories about body image and call for a more complex theory incorporating a more diverse range of experiences.

    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.

    This research proposed to investigate the effect of an intervention program to strengthen self-acceptance (positive), and a cognitive intervention program on body image. Specifically, it is based on the idea of prevention of risk factors for eating disorders from the perspective of normalcy in the prevention of body dissatisfaction. We used a 2×2 factorial design with 120 participants of both sexes, aged between 10 and 12 years, selected by stratification. To evaluate the hypothesis, we used two-way analysis of variance. The results concluded that only the cognitive intervention program affected the dependent variable body image, maintaining its statistical significance, which is revealed both in the general two-way ANOVA and when controlling the effect of the covariates, age and sex.

    Pitman, G E

    1999-01-01

    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.

    Recent studies have shown the importance of integrating multisensory information in the body representation for constituting self-consciousness. However, one idea that has received only scant attention is that our body representation is also constituted by knowledge of bodily visual characteristics (i.e. 'what I look like'). Here in two experiments we used a full body crossmodal congruency task in which visual distractors were presented on a photograph of the participant, another person, who was either familiar or unfamiliar, or an object. Results revealed that during the 'self-condition' CCEs were enhanced compared to the 'other condition'. The CCE was similar for unfamiliar and familiar others. CCEs for the object condition were significantly smaller. The results show that presentation of an irrelevant image of a body affects multimodal processing and that the effect is enhanced when that image is of the self. The results hold intriguing implications for body representation in social situations.

    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.

    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.

    Internet addiction is an increasing concern among young adults. Self-presentational theory posits that the Internet offers a context in which individuals are able to control their image. Little is known about body image and eating concerns among pathological Internet users. The aim of this study was to explore the association between Internet addiction symptoms, body image esteem, body image avoidance, and disordered eating. A sample of 392 French young adults (68 percent women) completed an online questionnaire assessing time spent online, Internet addiction symptoms, disordered eating, and body image avoidance. Fourteen men (11 percent) and 26 women (9.7 percent) reported Internet addiction. Body image avoidance was associated with Internet addiction symptoms among both genders. Controlling for body-mass index, Internet addiction symptoms, and body image avoidance were both significant predictors of disordered eating among women. These findings support the self-presentational theory of Internet addiction and suggest that body image avoidance is an important factor.

    To examine body image and possible distortion of body image among elite female dancers 10 members of a professional ballet company rated both current and ideal body shape. In addition, an objective measure of body composition was obtained via skinfold techniques. t tests indicated that the mean rating for current body image was significantly higher than the rating for ideal, despite the fact that body-composition measures for all subjects were in an "ideal" range according to normative standards. Analysis indicated a high distortion of body image among these dancers and support psychophysiological concerns previously raised.

    Negative body image attitudes are related to the onset of disordered eating, poor self-esteem, general mental health problems, and obesity. In this chapter, we will review the nature of body image attitudes in girls and boys in early (approximately 3-7 years old) and later childhood (approximately 8-11 years old). The body image attitudes explored in this chapter include body image attitudes related to the self, with a focus on body dissatisfaction, and body image attitudes related to others, with a focus on weight bias. Issues of measurement of body image and weight bias will first be explored. In light of measurement considerations, the prevalence and predictors of body dissatisfaction and related concerns, and weight bias will be examined. The chapter will conclude with a review of promising directions in the prevention of body dissatisfaction and weight bias in children.

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

    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.

    2016-10-01

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

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

    This study examined how exposure to media containing different body image content while exercising influenced exercise performance and feelings concerning appearance. 41 females completed two sessions of cycling (30 minutes). During exercise, participants viewed a television show that contained either media-portrayed ideal or neutral female body images. There were no differences in exercise performance between conditions. Physical appearance state anxiety (PASA) decreased post-exercise. After viewing ideal bodies, participants scored higher on appearance and comparison processing. The high internalization group scored higher on appearance and comparison processing and PASA increased following ideal body image content while the low internalization group decreased.

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

    This study tries to understand the differences in body experience between victims of sexual abuse and physical abuse. Ninety-eight women completed questionnaires that measured personal information, body-image aberration, body sensitivity and control, and body investment. Findings indicated that victims of sexual abuse demonstrate less body maintenance and protection in addition to greater injury to body sensitivity and control than victims of physical abuse. Moreover, comparing victims of sexual abuse to physical abuse, findings revealed that only victims of sexual abuse report body-image aberrations. Thus, sexual and physical abuse should be addressed discretely because each has differential effects on bodily attitudes of victims.

    In this study, we compared the effects of a 72-h exercise abstinence period and normal exercise on the affect and body dissatisfaction of 58 healthy women (mean age 26.1 years, s = 8.2) who exercised at least four times per week, and explored the relationship between the changes in affect and body dissatisfaction. Participants completed the UWIST-MACL and Body Dissatisfaction Scale to assess affect and body image, and were randomized to an abstinence or control group. Affect and body image for both groups were re-assessed following the 72-h abstinence period. Compared with the control group, the abstinence group had a significant decrease in hedonic tone and energetic arousal, and a significant increase in tense arousal and body dissatisfaction from pre-intervention to post-intervention. There were no significant relationships between the changes in body dissatisfaction and the components of affect. A 72-h exercise abstinence period resulted in increased affect disturbance and body dissatisfaction in regularly active women.

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

    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.

    Background Body image is a complex issue with the potential to impact many aspects of cancer survivorship, particularly for the younger breast cancer survivor. Objective The purpose of this review is to synthesize the current state of the science for body image in younger women with breast cancer. Intervention/Methods Combinations of the terms “body image,” “sexuality intervention,” “women,” “younger women,” and “breast cancer” were searched in the PubMed, PsycInfo, CINAHL, Web of Knowledge and Science Direct databases through January 2014. Inclusion criteria for this review were: 1) original research; 2) published in English from the year 2000 forward; 3) measuring body image as an outcome variable; and 4) results included reporting of age-related outcomes. Results Thirty-six articles met the inclusion criteria. The majority of studies were cross-sectional, with extensive variation in body image assessment tools. Age and treatment type had a significant impact on body image, and poorer body image was related to physical and psychological distress, sex and intimacy, and the partnered relationship among younger women. Only one intervention study found a significant improvement in body image post-intervention. Conclusions Findings suggest body image is a complex post-treatment concern for breast cancer survivors, particularly younger women. The findings of this review are limited by the high level of variation in the methods for assessing body image. Implications for Practice Further research of interventions to address body image concerns following treatment for breast cancer is warranted. Improvement of body image may improve the quality of life of younger breast cancer survivors. PMID:25881807

    The purpose of this study was to analyze the available evidence concerning the effects of breast reconstruction (BR) on body image of women with breast cancer. BR is a potential intervention to improve the body image of women with breast cancer. Conflicting research findings about the effects of breast reconstructive surgery on body image compared to breast conservative surgery (BCS) or mastectomy exist. A meta-analysis of studies found in MEDLINE, CINAHL, PsychINFO, PubMed as well as PQDT (dissertation and theses), and other unpublished literature resources from 1970 to 2010 were searched. Comparable studies that examined the difference of body image between breast cancer women receiving mastectomy plus BR and those with BCS were included. A clear definition about the domains of body image including body stigma, body concern, and transparency were identified. Mean effect sizes were calculated. Twelve studies were included in the meta-analysis. Women with BR and BCS were no different on the body concern domain of body image. However, women with BR had a significantly worse score on body stigma domain of body image than women receiving BCS. Women with BR had a better body image score than women with mastectomy. Women who are satisfied with their body shape may still perceive deficiencies because of the stigma of mastectomy and affect on body image. Consistent application of valid and reliable measures of body image specific to breast cancer women is needed.

    Background Body dysmorphic disorder (BDD) is defined as a syndrome characterized by an excessive preoccupation because of a presumed or minimal physical flaw in appearance that polarizes the energies of the subject. So far, its specular aspect, represented by the presence of an evident physical defect that is not recognized or is even denied and neglected, has been disregarded. The aim of our study was to examine the individual and relational meaning of BDD and to evaluate the efficacy of cognitive-behavioral and medical–aesthetical treatments. Methods and results We describe two subjects with BDD, diagnosed by clinical interviews and test. Both patients were compliant to cognitive-behavioral approach. One out of two subjects underwent aesthetical treatments. Conclusions Cognitive-behavioral therapy stimulates self-consciousness, rebuilds the body image, promotes health care, and improves relational capacity. Moreover, it ensures the success of any medical and/or surgical procedures by preventing unrealistic expectations. Lastly, it contributes to the definition of worldwide shared behavioral models.

    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.

    Body image is multifaceted and incorporates perceptual, affective, and cognitive components as well as behavioral features. Only few studies have examined the character of body-image disturbance in children/adolescents with eating disorders. It is unknown whether body-image disturbances in children/adolescent with eating disturbances are comparable to those of adult patients with eating disorders. Body-image disturbance might differ quantitatively and qualitatively according to the cognitive developmental status and the age of the individual. This paper provides an overview of the current evidence for body-image disturbance in children/adolescents with eating disorders, and how they compare with those adults with eating disorders. Current evidence indicates that older adolescent patients show similar deficits as adult patients with eating disorders, in particular for the attitudinal body-image component. However, evidence for a perceptual body-image disturbance in adolescent patients, in particular anorexia nervosa, is not conclusive. Reliable statements for childhood can hardly be made because clinical studies are not available. Investigations of body-image disturbance in children have focused on the predictive value for eating disorders. Limitations of the current evidence are discussed, and future directions for research and therapy are indicated.

    Patients with conversion disorder generally suffer from a severe neurological deficit which cannot be attributed to a structural neurological damage. In two patients with acute conversion paraplegia, investigation with functional magnetic resonance imaging (fMRI) showed that the insular cortex, a limbic-related cortex involved in body-representation and subjective emotional experience, was activated not only during attempt to move the paralytic body-parts, but also during mental imagery of their movements. In addition, mental rotation of affected body-parts was found to be disturbed, as compared to unaffected body parts or external objects. fMRI during mental rotation of the paralytic body-part showed an activation of another limbic related region, the anterior cingulate cortex. These data suggest that conversion paraplegia is associated with pathological activity in limbic structures involved in body representation and a deficit in mental processing of the affected body-parts.

    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.

    This study tested the efficacy of an Internet-based health promotion program, BodiMojo, designed to promote positive body image in adolescents. Participants were 178 students (mean age 15.2 years, 67.6% ethnic minority) in three public high schools. Intervention groups used BodiMojo for four weekly health class periods, while controls participated in their usual health curriculum. Body image measures were given at baseline, post-intervention, and 3 months. Girls reported decreased body dissatisfaction (p<.05), decreased physical appearance comparison (p<.05), and increased appearance satisfaction (p<.05), relative to controls. Effects were not maintained at 3-month follow-up. No significant differences were found between the intervention and control groups with boys. Moderation analyses suggested positive effects for diverse adolescents as well as those who were overweight or indicated baseline high body dissatisfaction. BodiMojo appears to be modestly effective in decreasing body image concerns among adolescent girls in the short term.

    Various components of body image were measured to assess body image disturbances in patients with obesity. To overcome limitations of previous studies, a photo distortion technique and a biological motion distortion device were included to assess static and dynamic aspects of body image. Questionnaires assessed cognitive-affective aspects, bodily attitudes, and eating behavior. Patients with obesity and a binge eating disorder (OBE, n = 15) were compared with patients with obesity only (ONB; n = 15), to determine the nature of any differences in body image disturbances. Both groups had high levels of body image disturbances with cognitive-affective deficits. Binge eating disorder (BED) participants also had perceptual difficulties (static only). Both groups reported high importance of weight and shape for self-esteem. There were some significant differences between the groups suggesting that a comorbid BED causes further aggravation. Body image interventions in obesity treatment may be warranted.

    Adolescence is a period marked by important physical and social changes that can lead to a negative body image. The purpose of this study was to find a model enabling the appearance of behavioral impairment related to body image (restrictions, avoidance, and checking) to be predicted by body image attitudes (concern or Appearance Orientation, and dissatisfaction or Appearance Evaluation), Gender, emotional symptomatology, self-consciousness, ideas of reference (IR) and age. A total of 661 participants (67.47% girls) with an average age of 17.14 years (SD=2.34) filled in the GHQ-28, SCS on self-consciousness, REF referential thinking scale, MBSRQ (AO and AE), and BIAQ. A partial mediation model was found for IR, age and depressive symptomatology between dissatisfaction and concern about body image and Gender, to behavioral impairment related to body image. The results found suggest that age, depressive symptomatology, and IR may be mediator variables in the relationship between dissatisfaction and concern about body image, on body image behavioral impairment. This relationship implies a severity to be considered in intervention and monitoring of body image behavioral impairments in adolescents.

    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.

    Talk about physical appearance and body image is common among young women. We investigated how body talk (negative, positive/self-accepting, and co-ruminative) is related to body image, body-related cognitive distortions, disordered eating, psychological adjustment, and friendship quality via hierarchical regression analyses (controlling for social desirability and body mass index). In a sample of young adult women (N=203), negative body talk was, as predicted, negatively related to body satisfaction and self-esteem and positively related to appearance investment, body-related cognitive distortions, disordered eating, and depression, but not friendship quality. Self-accepting/positive body talk was negatively related to body-related cognitive distortions and positively related to body satisfaction, self-esteem, and friendship quality. Body-related co-rumination demonstrated adjustment trade-offs, being related to body-related cognitive distortions, disordered eating, and higher friendship quality. Results indicated no advantage to negative body talk, both individual and relationship benefits from positive/self-accepting body talk, and mixed outcomes for body-related co-rumination.

    2016-01-01

    Female adolescent oncology patients undergo many physical changes throughout treatment that have challenging psychological, emotional, and social implications. 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.

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

    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 x faces, 1003 hits for emotion x music and 339 hits for emotion x bodies. When looking in more detail, the body x 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

    2006-07-01

    Common features of polycystic ovary syndrome (PCOS), including hyperandrogenism, ovarian dysfunction and obesity, can be highly distressing. We compared 40 women with PCOS to women with infertility but not PCOS, and to women with neither PCOS nor infertility, on measures of depression and body image. Women with PCOS reported higher depression scores and greater body dissatisfaction (p < .001) than comparison group women. Body image was strongly associated with depression overall, even after controlling body mass. Among women with PCOS, body dissatisfaction measures and education explained 66 percent of the variance in depression, suggesting explanations of the PCOS-depression link should consider the role of potentially mediating psychosocial variables.

    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.

    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.

  2. Factors that Influence Body Image Representations of Black Muslim Women

    2008-01-01

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

    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.

    2011-06-01

    Although muscularity and body fat concerns are central to conceptualizing men's body image, they have not been examined together within existing structural models. This study refined the tripartite influence model (Thompson, Heinberg, Altabe, & Tantleff-Dunn, 1999) by including dual body image pathways (muscularity and body fat dissatisfaction) to engagement in muscular enhancement and disordered eating behaviors, respectively, and added dating partners as a source of social influence. Latent variable structural equation modeling analyses supported this quadripartite model in 473 undergraduate men. Nonsignificant paths were trimmed and two unanticipated paths were added. Muscularity dissatisfaction and body fat dissatisfaction represented dual body image pathways to men's engagement in muscularity enhancement behaviors and disordered eating behaviors, respectively. Pressures to be mesomorphic from friends, family, media, and dating partners made unique contributions to the model. Internalization of the mesomorphic ideal, muscularity dissatisfaction, and body fat dissatisfaction played key meditational roles within the model.

    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.

    This study investigated disturbances in body image perception with anorexic, obese and control groups (N = 24). Each group was comprised of 8 female subjects matched for age. An original silhouette chart and chi squares were employed, and a significant difference was found among the groups in the perception of the present-self body image (chi 2 (8) = 24.19, p less than .01), body image at plus 10 pounds (chi 2 (6) = 27.63, p less than .01), and body image at minus 10 pounds (chi 2 (8) = 26.05, p less than .01). No differences among the groups appeared in perceived ideal-self body image or in their perception of the body image that was expected from their families. A directional trend was noted in anorexic overestimation and obese underestimation on the total concept of body image. Significant differences among the groups as judged via a semantic differential technique were found for personality descriptions of happy/sad, active/passive, popular/unpopular, effective/ineffective, competent/incompetent, smart/stupid, and cold/warm.

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

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

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

This article reviews eating pathology and body image concerns in four diverse groups in the U.S. (African Americans, Latino/as, Asians, and Native Americans). The major conclusion based on this review is that eating disturbances and body dissatisfaction occur to some degree in children and adolescents from all four major ethnic groups in the U.S; however, there is substantial variability across studies. Future directions include the need for studies of prevalence, prevention and treatment research, and investigations of neurobiological and genetic variables.

  14. Optoacoustic imaging: application to the detection of foreign bodies

    Detection of non-radio-opaque foreign bodies can be difficult. Current imaging modalities employed for detection of foreign bodies include: X-ray computed tomography, magnetic resonance, and ultrasound. Successful diagnosis of the presence of foreign bodies is variable because of the difficulty of differentiating them from soft tissue, gas, and bone. We are applying laser-induced optoacoustic imaging to the detection of foreign bodies. Tissue-simulating phantoms containing various common foreign bodies have been constructed. Images of these phantoms were generated by two laser-based optoacoustic methods utilizing different detection modalities. A pre-commercial imager developed by Seno Medical Instruments (San Antonio), incorporated an ultrasound transducer to detect induced optoacoustic responses, while a laboratory-built imaging system utilized an optical probe beam deflection technique (PBDT) to detect the optoacoustic responses. The laboratory-built unit also included an optical parametric oscillator as the pump, providing tunable wavelength output to optimize the optoacoustic measurements by probing the foreign bodies at their maximum optical absorption. Results to date have been encouraging; both methodologies have allowed us to reconstruct successfully the image of foreign-body containing phantoms. In preliminary work the PBDT approach appeared to produce higher resolution than did the ultrasound detector, possibly because PBDT is not constrained by the lower bandwidth limit imposed on the ultrasound transducer necessary to increase imaging depth. During the research in progress, we will compare the optoacoustic images to those generated by MRI, CT, and ultrasound, and continue to improve the resolution of the technique by using multiple detection sensors, and to improve image contrast by scanning foreign bodies over a range of wavelengths.

    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.

  16. Whole-body and multispectral photoacoustic imaging of adult zebrafish

    2016-10-01

    Zebrafish is a top vertebrate model to study developmental biology and genetics, and it is becoming increasingly popular for studying human diseases due to its high genome similarity to that of humans and the optical transparency in embryonic stages. However, it becomes difficult for pure optical imaging techniques to volumetric visualize the internal organs and structures of wild-type zebrafish in juvenile and adult stages with excellent resolution and penetration depth. Even with the establishment of mutant lines which remain transparent over the life cycle, it is still a challenge for pure optical imaging modalities to image the whole body of adult zebrafish with micro-scale resolution. However, the method called photoacoustic imaging that combines all the advantages of the optical imaging and ultrasonic imaging provides a new way to image the whole body of the zebrafish. In this work, we developed a non-invasive photoacoustic imaging system with optimized near-infrared illumination and cylindrical scanning to image the zebrafish. The lateral and axial resolution yield to 80 μm and 600 μm, respectively. Multispectral strategy with wavelengths from 690 nm to 930 nm was employed to image various organs inside the zebrafish. From the reconstructed images, most major organs and structures inside the body can be precisely imaged. Quantitative and statistical analysis of absorption for organs under illumination with different wavelengths were carried out.

    This study examined factors that influence body image and strategies to either lose weight or increase muscle among children. Participants were 237 boys and 270 girls. Body mass index (BMI), body dissatisfaction, cognitions and behaviors to both lose weight and increase muscles, as well as self-esteem and positive and negative affect, were evaluated. Self-esteem was associated with body satisfaction, positive affect predicted strategies to lose weight and increase muscles, and negative affect predicted body dissatisfaction and cognitions to lose weight and increase muscles. Boys were more likely to focus on changing muscles. Respondents with higher BMIs were more focused on losing weight butnot muscle. The discussion focuses on health risk behaviors related to eating and exercise among children.

    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.

    The study illustrates a research on the relationship between body image and lifestyles in a sample of 262 young amateur athletes that have a regular attendance of a gym in Cassino (Central Italy). The following questionnaires were used: Body Shape Questionnaire (BSQ34), International Physical Activity Questionnaire (IPAQ), Short form 12 items (SF12). The participants were 257 (response rate 98.1%) mainly of young age (18-24 years, 63.8%), single (72%), with a senior high school diploma (57.2%), students (63%). For almost all the BSQ-34 questionnaire items differences for gender were found, with Females more worried than males. 187 (72.8%) reported some vigorous activity during a week, 207 (80.5%) some moderate activity, and 229 (89.1%) walking. The participants had a median PCS score of 54.2 (range: 24.5-64.8) and a median MCS score of 43.8 (range: 9.3 - 58.7). The mean score of the Mediterranean diet was 4.8 (median = 5; Range = 1-8), and only 72 individuals (11.7%) had optimal score (over or equal to 6).

    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.

    The aim of the study was to examine the correlation among different indicators of body image; between each one of these and nutritional status; and the association of these indicators with the Body Mass Index (BMI) of adolescents. A random sample of 152 students from public and private schools in the city of Rio de Janeiro, Brazil, was studied. On four occasions, two silhouette scales and two questions regarding the opinion of the student about his/her body and weight were applied and weight and height were measured. The BMI was examined both as a continuous and as a categorical variable. The agreement between the variables was analyzed using the quadratic weighted Kappa statistics. The association between body image variables and BMI was examined by the comparison among median, mean, standard deviation and 95% confidence interval of BMI for each category of the body image variables. In general, the correlation among the body image variables ranged from reasonable to good; between these and the variable nutritional status, correlation ranged from regular to reasonable. Best results were observed among boys and students from private schools. All body image variables showed good discriminatory power for BMI, when it was analyzed as a continuous variable, even when controlling for potential confounders. The question about body seems to be better than that about weight to compose the questionnaire of a surveillance system for risk and protective factors for adolescent health.

    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

    The scope of this article is to investigate associations between body image dissatisfaction and sociodemographic indicators among adolescents. Participants included 1126 high school students in the city of Santa Maria in the State of Rio Grande do Sul. Aspects regarding body image dissatisfaction and sociodemographic indicators were analyzed. Association analyses were performed using crude Poisson regression duly adjusted for sex and age. Boys were found to be dissatisfied due to slimness and girls due to excess weight. Adolescents where the parents had less schooling, as well as those from lower socioeconomic classes and with lower income were found to be more likely to have body image dissatisfaction due to slimness. However, those where the parents had completed higher education and those living in the downtown area were more likely to have body image dissatisfaction due to excess weight. Sociodemographic indicators are closely associated with body image dissatisfaction. Body image dissatisfaction due to slimness can be explained by the lower level of schooling of the parents, lower socioeconomic class and lower income. Dissatisfaction due to excess weight can be explained by the higher schooling of the parents and the fact of living in the downtown area.

    Background: Abnormal body sensations are reported frequently by schizophrenic patients. Cenesthesias are infrequently recognized and diagnosis of cenesthopathic schizophrenia is rarely made. There are very few studies regarding the same. Aims and Objectives: To assess cenesthesias and different aspects of body image aberration and their relationship with psychopathology in patients with paranoid schizophrenia. Materials and Methods: Seventy patients of paranoid schizophrenia meeting the inclusion and exclusion criteria were assessed with Positive and Negative Symptom Scale(PANSS) for psychopathology, Bonn Scale for Assessment of Basic Symptoms/Category D ‘Cenesthesias’ (BSABS), Image-Marking Procedure(IMP), alteration of body size and body cathexis. Assessments were made at baseline and after two weeks and assessed with SPSS 12.0. Results: The most commonly endorsed items on BSABS were depersonalization, motor weakness, abnormal pain, numbness and stiffness. Patients underestimated lower extremities and feelings of body size change which was positively correlated with PANSS-scores and improved on reassessment. Cenesthesias were positively correlated with disturbances of body concept and were present at onset in 40% and change form in 75.7%. Conclusions: Cenesthesias and body image aberrations are common in paranoid schizophrenia. They are present from onset in few, change form and improve on treatment. Cenesthesias and disturbances of body concept are correlated and body size is associated with other psychopathology. PMID:19881047

    Using survey results from the 1998 Twin Cities Lesbian, Gay, Bisexual, and Transgender (LGBT) Pride Festival (N = 535), we explored associations between body image and unsafe anal intercourse (UAI) among men who have sex with men (MSM), and evaluated whether body satisfaction mediated this association. MSM who reported underweight body image had lower odds than those who reported average weight of UAI (AOR = 0.33; 95% CI = 0.13, 0.85); body satisfaction was not found to mediate this association. 13.3% of men who reported overweight/obese body image had engaged in UAI compared with 21.6% of those who reported average weight and 8.2% of those who reported underweight (p < .05). Compared with MSM in exclusive relationships, MSM in non exclusive relationships had increased odds of UAI (AOR = 5.78; 95% CI = 2.96, 11.29) as did men who were not partnered (AOR = 3.20; 95% CI = 1.72, 5.93). These findings highlight the importance of including body image in sexual behavior models of MSM to better understand body image's role in influencing sexual risk and sexually transmitted infections (STI)/human immunodeficiency virus (HIV) transmission.

    Three-dimensional intra- and intersubject registration of image volumes is important for tasks that include quantification of temporal/longitudinal changes, atlas-based segmentation, computing population averages, or voxel and tensor-based morphometry. While a number of methods have been proposed to address this problem, few have focused on the problem of registering whole body image volumes acquired either from humans or small animals. These image volumes typically contain a large number of articulated structures, which makes registration more difficult than the registration of head images, to which the majority of registration algorithms have been applied. This article presents a new method for the automatic registration of whole body computed tomography (CT) volumes, which consists of two main steps. Skeletons are first brought into approximate correspondence with a robust point-based method. Transformations so obtained are refined with an intensity-based nonrigid registration algorithm that includes spatial adaptation of the transformation's stiffness. The approach has been applied to whole body CT images of mice, to CT images of the human upper torso, and to human head and neck CT images. To validate the authors method on soft tissue structures, which are difficult to see in CT images, the authors use coregistered magnetic resonance images. They demonstrate that the approach they propose can successfully register image volumes even when these volumes are very different in size and shape or if they have been acquired with the subjects in different positions.

    Hill, Mary L; Masuda, Akihiko; Latzman, Robert D

    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.

  17. A Portable Stereo Vision System for Whole Body Surface Imaging.

    PubMed

    Yu, Wurong; Xu, Bugao

    2010-04-01

    This paper presents a whole body surface imaging system based on stereo vision technology. We have adopted a compact and economical configuration which involves only four stereo units to image the frontal and rear sides of the body. The success of the system depends on a stereo matching process that can effectively segment the body from the background in addition to recovering sufficient geometric details. For this purpose, we have developed a novel sub-pixel, dense stereo matching algorithm which includes two major phases. In the first phase, the foreground is accurately segmented with the help of a predefined virtual interface in the disparity space image, and a coarse disparity map is generated with block matching. In the second phase, local least squares matching is performed in combination with global optimization within a regularization framework, so as to ensure both accuracy and reliability. Our experimental results show that the system can realistically capture smooth and natural whole body shapes with high accuracy.

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

    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 aim of this study was to examine the influence of yoga practice on body image satisfaction in men. Male Figure Drawings were used to explore body image satisfaction in yoga beginners (n = 26, M age = 40.3 yr., SD = 11.6), experienced yoga practitioners (n = 22, M age = 46.4 yr., SD = 11.6), and non-yoga practicing aerobic and weight training exercisers (n = 34, M age = 41.2 yr., SD = 11.9). Satisfaction was significantly higher among the yoga groups than the exercisers. There was no statistical difference between the body satisfaction scores of the experienced yoga group and the beginner yoga students. This may suggest that individuals drawn to yoga have greater body satisfaction than exercisers, and that regular yoga practice possibly further increases body satisfaction.

    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

  7. Loving transgressions: Queer of color bodies, affective ties, transformative community.

    Carrillo Rowe, Aimee; Royster, Francesca T

    2016-09-12

    This introductory article considers the importance of queer woman of color theorizations of affect in thinking more fully the recent interdisciplinary turn to affect. The affective turn has vitally invited culture and feminist critics to interrogate emotion beyond the individual to examine the political and cultural production of emotion. Even as women of color are often associated with excessive affect, the theoretical contributions women of color make to the field of affect studies are often overlooked. Our introduction and this special issue more broadly examine how this solipsism shapes projects invested in critical knowledge production, as well as the stakes of centering a queer woman of color genealogy. For instance, we argue for the importance of retaining U.S. third-world feminist concepts-like interpellation, oppositional consciousness, and the generative force of negative affects-even as they fall out of favor within affect studies. Centering theory that emerges from the vexed spaces of queer women of color lived experiences generates a vital interdisciplinary conversation that contributes to the ongoing political task of mobilizing affect for social action as a critical praxis. In the articles that follow we see this critical praxis at work in the form of community organizing, music, poetry, and performance art.

    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.

    Parry-Romberg syndrome, which is also known as progressive hemifacial atrophy, is a poorly understood rare condition. In this condition, the face shows unilateral, slowly progressive atrophy. Disturbance in fat metabolism, viral infection, trauma, heredity, endocrinal disturbances, and autoimmunity are few possible factors in its pathogenesis. Rarely, only this syndrome progresses and involves one half of the body. Our attempt is to present a case of Parry–Romberg syndrome involving one half of the body, which is a rarity in itself.

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

    2014-01-01

    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

    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.

    Objective To gain a holistic and deep understanding about how mastectomy effects the body image of women who have breast cancer. Materials and Methods The sample of this qualitative descriptive study consisted of twenty patients who underwent mastectomy procedures. Semi-structured interviews were conducted during the second week after mastectomy. Each interview was transcribed verbatim, and a thematic analysis was performed. Results After the mastectomy, the findings related to the women’s body image and their experiences were specified as four main themes and seven sub-themes. The main themes were: meaning of the breast, mastectomy and me, my body image and body image changes, and social life. Most of the participants in this study stated that the breast meant femininity, beauty, and motherhood. It was found that the meaning of mastectomy varied according to individuals. Women used quite negative statements about their appearances. The participants also said that they felt that half themselves was missing, as individuals and women. The women stated that they preferred clothes that hid their lack of breast. Some of the participants mentioned that relations with their husbands were not like before, and they abstained from social interaction. Conclusion Our findings suggest that mastectomy as a surgical treatment for breast cancer may negatively affect a woman’s body image and her self-image.

    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.

    This documentary, qualitative, descriptive study has the objective to analyze images and representations of the female body and their relation to drug use in the content of articles published in four magazines with national circulation (Veja, Isto E, Boa Forma, Claúdia). The articles selected were submitted to the technique of content analysis, with three thematic groups identified: the body as an incentive to use drugs; risks to the body resulting from drug use; and the search for the perfect body through drug use. The data showed that the media reproduces rigid aesthetic standards, exposing women to social and health offenses that stimulate drug use, either autonomously or by prescription. The search for beauty and the appeal to feminine eroticism, published through the communication channels analyzed limit the social importance of women by using images that link them to the status of sexual object.

    BACKGROUND: Breast cancer is the most common cancer in women. Surgical treatment of breast cancer may cause body image alterations. The purpose of the current study was to examine the effects of cognitive behavioral counseling on body image among Iranian women with primary breast cancer. METHODS: In this quasi-experimental designed study, 72 patients diagnosed as breast cancer and surgically treated were enrolled in Isfahan, Iran. The patients were entered the study by convenience sampling method and were randomly divided in two groups of intervention (n = 32) and control (n = 40). The intervention group received consultation based on Ellis rational emotive behavior therapy (REBT) method for 6 sessions during 3 weeks. The control group did not receive any consultation Paired t-test was used to compare the changes in groups and independent t-test was conducted to compare two groups. The average values represented as mean ± standard deviation. RESULTS: Before the study, the body image score was not significantly different between the intervention (16 97 ± 5 44) and control (15 95 ± 4 66) groups (t = 0 86, P = 0 395). The body image score was significantly lower in the interven-tion group (9 03 ± 6 11) compared to control group (17 18 ± 5 27) after the intervention (t = -6 07, P < 0 001). CONCLUSIONS: Since a woman's body image influences her breast cancer treatment decision, oncology professionals need to recognize the value of a woman's favorite about appearance and body image. This study emphasizes the importance of offering consultation in breast cancer patients. PMID:22279481

    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.

  1. Does smoking affect body weight and obesity in China?

    2009-12-01

    An inverse relationship between smoking and body weight has been documented in the medical literature, but the effect of cigarette smoking on obesity remains inconclusive. In addition, the evidence is mixed on whether rising obesity rates are an unintended consequence of successful anti-smoking policies. This study re-examines these relationships using data from China, the largest consumer and manufacturer of tobacco in the world that is also experiencing a steady rise in obesity rates. We focus on the impact of the total number of cigarettes smoked per day on individuals' body mass index (BMI) and on the likelihood of being overweight and obese. Instrumental variables estimation is used to correct for the endogeneity of cigarette smoking. We find a moderate negative and significant relationship between cigarette smoking and BMI. Smoking is also negatively related to being overweight and obese, but the marginal effects are small and statistically insignificant for being obese. Quantile regression analyses reveal that the association between smoking and BMI is quite weak among subjects whose BMIs are at the high end of the distribution but are considerably stronger among subjects in the healthy weight range. Ordered probit regression analyses also confirm these findings. Our results thus reconcile an inverse average effect of smoking on body weight with the absence of any significant effect on obesity. From a policy perspective these findings suggest that, while smoking cessation may lead to moderate weight gain among subjects of healthy weight, the effects on obese subjects are modest and should not be expected to lead to a large increase in obesity prevalence rates.

    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

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

    1993-01-01

    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

    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.

    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.

    Dieting is becoming a popular phenomenon among university students to achieve or maintain a healthy weight. The purpose of this study is to obtain a preliminary understanding of what dieting practices university students use in order to achieve their desirable body weight and to determine the magnitude of body dissatisfaction in relation to weight status among a sample of students (n=252) from the Lebanese American University in Beirut, Lebanon. Students filled out a self-reported questionnaire that included questions on their dieting and physical activity practices in addition to the body shape questionnaire (BSQ). Weight and height were measured to calculate body mass index. Percentage body fat was measured using Tanita scale body fat analyzer 300A. The outcome of this study showed that smoking and unhealthy dieting practices were not common among students (only 26% reported smoking, 8% reported taking laxatives and 4% taking diet pills). Half of the students reported practicing regular physical activity. Multivitamin intake was also not popular among students. BSQ scores indicate that the majority of students were not worried about their body image perception (64% reported not being worried, 19% were slightly worried, 12% were moderately worried and 5% were extremely worried). A gender difference was observed in the BSQ scores, as 89% of the "extremely worried" students were females. Collectively, results indicate that unhealthy dieting practices are uncommon among students. However, developing health promotion awareness' programs to promote good self image within the concept of a realistic healthy weight will be beneficial, especially among females.

    Does the prevalence and degree of body dissatisfaction differ among heterosexual and homosexual men and women? Some theorists have suggested that, compared to their heterosexual peers, gay men are at greater risk for body dissatisfaction and lesbians at lower risk. Past studies examining this issue have generally relied on small samples recruited from gay or lesbian groups. Further, these studies have sometimes produced conflicting results, particularly for comparisons of lesbian and heterosexual women. In the present research, we compared body satisfaction and comfort with one's body during sexual activity among lesbian women, gay men, heterosexual women, and heterosexual men through two large online studies (Ns = 2,512 and 54,865). Compared to all other groups, heterosexual men reported more positive evaluations of their appearance, less preoccupation with their weight, more positive effects of their body image on their quality of life and the quality of their sex life, more comfort wearing a swimsuit in public, and greater willingness to reveal aspects of their body to their partner during sexual activity. Few significant differences were found among gay men, lesbian women, and heterosexual women. Many gay men (42%) reported that their feelings about their body had negative effects on the quality of their sex life, as did some lesbian women (27%), heterosexual women (30%), and heterosexual men (22%). Overall, the findings supported the hypothesis that gay men are at greater risk than heterosexual men for experiencing body dissatisfaction. There was little evidence that lesbian women experience greater body satisfaction than heterosexual women.

  9. Three-dimensional coherence of the conscious body image.

    Longo, Matthew R

    2015-01-01

    We experience our body as a coherent object in the three-dimensional (3-D) world. In contrast, the body is represented in somatosensory cortex as a fragmented collection of two-dimensional (2-D) maps. Recent results have suggested that some forms of higher level body representations maintain this fragmentation, for example by showing different patterns of distortion for two surfaces of a single body part, such as the palmar and dorsal hand surfaces. This study investigated the 3-D coherence of the conscious body image of the hand by comparing perceptual biases of perceived hand shape on the dorsal and palmar surfaces. Participants made forced-choice judgements of whether observed hand images were thinner or wider than their own left or right hand, and perceptual distortions of the hand image were assessed by fitting psychometric functions. The results suggested that the hand is consciously represented as a fully coherent, 3-D object. Specifically: (a) Similar overall levels of distortion were found on the palmar and dorsal hand surfaces, (b) comparable laterality effects were found on both surfaces (left hand represented as wider than right hand), and (c) the magnitude of distortions were strongly correlated across the two surfaces. Whereas other recent results have suggested that perceptual abilities such as position sense, tactile size perception, and tactile localization may rely on fragmented, 2-D representations of individual skin surfaces, the present results suggest that, in striking contrast, the conscious body image represents the body (or, at least the hand) as a coherent, 3-D object.

    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

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).

    The 'Distressed' or Type-D personality is described by the interaction between high levels of negative affectivity and social inhibition. This study investigated the prevalence of Type-D personality in men of different exercise status, the association between Type-D and body image perceptions, and the moderating effect of exercise status. Participants were 564 British males aged between 18 and 55 years. Of these 200 were classified as sedentary, 148 as active and 216 as weight trainers. Participants completed the DS14 and Multidimensional Body-Self Relations Questionnaire. Results showed that more individuals were classified as Type-D in the sedentary group (45%) than the two active groups, and in the weight training (24.5%) than the active (14.2%) group. Both Type-D and a sedentary lifestyle were associated with a significantly poorer body image. However, exercise mode was not associated with body image differences. Sedentary Type-D men scored significantly lower in Body Areas Satisfaction and higher in Self-Classified Weight than both active groups. Regular exercise might provide a pathway for Type-D men to develop a more positive body image.

    Background Methamphetamine (MA) is a highly addictive stimulant which has destructive effects. There is also evidence that methamphetamine use in some females, partly is due to their desire to lose weight. The purpose of this study was to determine the association between family flexibility, food preoccupation and body image among crystal abuser women. Objectives This study tried to evaluate whether food preoccupation, body image and family flexibility affect on crystal abuse in women. Patients and Methods Eighty crystal abuser women were chosen with convenience sampling and they responded to instrument of body image (Fisher), family flexibility (Olson) and food preoccupation (Tapper) questionnaires. Results There is a significant association between family flexibility and food preoccupation (P < 0.01) and also other variables; there is no significant association between family flexibility and body image, body image and food preoccupation (P > 0.05). Also, family flexibility is prediction of food preoccupation (P < 0.01). Conclusions These results emphasize that the components of eating behaviors (e.g. food preoccupation) and family flexibility can be considered in therapeutic interventions (prevention and treatment) for women to crystal withdrawal.

    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.

  4. Appearance-based exercise motivation moderates the relationship between exercise frequency and positive body image.

    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.

    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.

    Fouling of the solid lying area in pig housing is undesirable for reasons of animal welfare, animal health, environmental pollution, and labor costs. In this study the influence of temperature on the excreting and lying behavior of growing-finishing pigs of different BW (25, 45, 65, 85, or 105 kg) was studied. Ten groups of 5 pigs were placed in partially slatted pens (60% solid concrete, 40% metal-slatted) in climate respiration chambers. After an adaptation period, temperatures were raised daily for 9 d. Results showed that above certain inflection temperatures (IT; mean 22.6 degrees C, SE = 0.78) the number of excretions (relative to the total number of excretions) on the solid floor increased with temperature (mean increase 9.7%/ degrees C, SE = 1.41). Below the IT, the number of excretions on the solid floor was low and not influenced by temperature (mean 13.2%, SE = 3.5). On average, the IT for excretion on the solid floor decreased with increasing BW, from approximately 25 degrees C at 25 kg to 20 degrees C at 100 kg of BW (P < 0.05). Increasing temperature also affected the pattern and postural lying. The temperature at which a maximum number of pigs lay on the slatted floor (i.e., the IT for lying) decreased from approximately 27 degrees C at 25 kg to 23 degrees C at 100 kg of BW (P < 0.001). At increasing temperatures, pigs lay more on their sides and less against other pigs (P < 0.001). Temperature affects lying and excreting behavior of growing-finishing pigs in partially slatted pens. Above certain IT, pen fouling increases linearly with temperature. Inflection temperatures decrease at increasing BW.

    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.

  11. 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.

  12. Does Body Mass Index Affect Mortality in Coronary Surgery?

    PubMed Central

    Protopapas, Aristotle D.

    2016-01-01

    Introduction: The Body Mass Index (BMI) quantifies nutritional status and classifies humans as underweight, of normal weight, overweight, mildly obese, moderately obese or morbidly obese. Obesity is the excessive accumulation of fat, defined as BMI higher than 30 kg/m2. Obesity is widely accepted to complicate anaesthesia and surgery, being a risk factor for mediastinitis after coronary artery bypass grafting (CABG). We sought the evidence on operative mortality of CABG between standard BMI groups. Materials and Methodology: A simple literature review of papers presenting the mortality of CABG by BMI group: Underweight (BMI ≤ 18.49 kg/m2), normal weight (BMI 18.5–24.9 kg/m2), overweight (BMI 25.0–29.9 kg/m2), mild obesity (BMI 30.0–34.9 kg/m2), moderate obesity (BMI 35.0–39.9 kg/m2), or morbid obesity (BMI ≥ 40.0 kg/m2). Results: We identified 18 relevant studies with 1,027,711 patients in total. Their variability in size of samples and choice of BMI groups precluded us from attempting inferential statistics. The overall cumulative mortality was 2.7%. Underweight patients had by far the highest mortality (6.6%). Overweight patients had the lowest group mortality (2.1%). The group mortality for morbidly obese patients was 3.44%. Discussion: Patients with extreme BMI’s undergoing CABG (underweight ones more than morbidly obese) suffer increased crude mortality. This simple observation indicates that under nutrition and morbid obesity need be further explored as risk factors for coronary surgery. PMID:28217179

    Stahl, Devan

    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.

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

    Hepatic disease is often treatable and has a predictable prognosis when a definitive diagnosis is made. The aim of clinicopathological evaluation of hepatobiliary affections is to identify and characterize hepatic damage and dysfunction, identify possible primary causes of secondary liver disease, differentiate causes of icterus, evaluate potential anaesthetic risks, assess prognosis and response to xenobiotics, and monitor response to therapy. This paper describes the different diagnostic methods and imaging techniques employed in diagnosis of hepatobiliary affections in dogs. Besides reviewing the significant clinical manifestations and imaging structural abnormalities in diagnostic approach to different hepatic affections, it also depicts radiographic, ultrasonographic, and wherever applicable, the laparoscopic characterization of different hepatic affections and target lesions encountered in clinical cases presented in the Teaching Veterinary Clinical Complex, COVAS, Palampur in the year 2007-2008.

  18. Media images, body dissatisfaction, and disordered eating in adolescent women.

    PubMed

    Andrist, Linda C

    2003-01-01

    This article examines the literature related to the media, body image, and diet/weight issues in children and young women. The media holds an awesome power to influence young women, bombarding them with images of abnormally thin models who seem to represent the ideal. When the majority of adolescents inevitably fail to achieve the extremely thin image they crave, body dissatisfaction results, and disordered eating can begin. Emerging research in the pediatric and adolescent literature demonstrates that children as young as 5 are already anxious about their bodies, and want to be thinner. This obsessive interest in body weight is only fueled by a dramatic increase in the number of Internet Web sites devoted to disordered eating. Unfortunately many of the Web sites are "pro-ana" (pro anorexia) and "pro-mia" (pro bulimia); these Web sites encourage young people at risk to begin starving themselves, or to begin binge-purging. As nurses know, each of these scenarios can lead to serious illness, and sometimes to death.

    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.

    Whole-body imaging in children was classically performed with radiography, positron-emission tomography, either combined or not with computed tomography, the latter with the disadvantage of exposure to ionizing radiation. Whole-body magnetic resonance imaging (MRI), in association with the recently developed metabolic and functional techniques such as diffusion-weighted imaging, has brought the advantage of a comprehensive evaluation of pediatric patients without the risks inherent to ionizing radiation usually present in other conventional imaging methods. It is a rapid and sensitive method, particularly in pediatrics, for detecting and monitoring multifocal lesions in the body as a whole. In pediatrics, it is utilized for both oncologic and non-oncologic indications such as screening and diagnosis of tumors in patients with genetic syndromes, evaluation of disease extent and staging, evaluation of therapeutic response and post-therapy follow-up, evaluation of non neoplastic diseases such as multifocal osteomyelitis, vascular malformations and syndromes affecting multiple regions of the body. The present review was aimed at describing the major indications of whole-body MRI in pediatrics added of technical considerations.

    With a prevalence of 15-21%, dyspareunia is one of the most commonly reported sexual dysfunctions in pre-menopausal women under the age of 40. Studies to date have focused primarily on clinical samples, showing that women with dyspareunia report overall sexual impairment, anxiety, and feelings of sexual inadequacy. However, little is known about their body image and genital self-image and few studies have sampled women exclusively from the general population. The aim of the present, controlled study was to investigate body image and genital self-image in a community sample of pre-menopausal women with self-reported dyspareunia. In total, 330 women completed an online survey, of which 192 (58%) had dyspareunia and 138 (42%) were pain-free control women. In comparison to pain-free control women, women with dyspareunia reported significantly more distress about their body image and a more negative genital self-image. Moreover, findings from a logistic regression, in which trait anxiety was controlled for, showed that a more negative genital self-image was strongly and independently associated with an increased likelihood of reporting dyspareunia. These results suggest that, in women with dyspareunia, body image and genital self-image are significantly poorer and would benefit from more attention from both clinicians and researchers.

    The term stereotactic body radiation therapy (SBRT) describes a recently introduced external beam radiation paradigm by which small lesions outside the brain are treated under stereotactic conditions, in a single or few fractions of high-dose radiation delivery. Similar to the treatment planning and delivery process for cranial radiosurgery, the emphasis is on sparing of adjacent normal tissues through the creation of steep dose gradients. Thus, advanced methods for assuring an accurate relationship between the target volume position and radiation beam geometry, immediately prior to radiation delivery, must be implemented. Such methods can employ imaging techniques such as planar (e.g., x-ray) or volumetric (e.g., computed tomography [CT]) approaches and are commonly summarized under the general term image-guided radiation therapy (IGRT). This review summarizes clinical experience with volumetric and ultrasound based image-guidance for SBRT. Additionally, challenges and potential limitations of pre-treatment image-guidance are presented and discussed.

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.

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

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

    Despite recent advances in developing evidence-based psychological interventions, substantial changes are needed in the current system of intervention delivery to impact mental health on a global scale (Kazdin & Blase, 2011). Prevention offers one avenue for reaching large populations because prevention interventions often are amenable to scaling-up strategies, such as task-shifting to lay providers, which further facilitate community stakeholder partnerships. This paper discusses the dissemination and implementation of the Body Project, an evidence-based body image prevention program, across 6 diverse stakeholder partnerships that span academic, non-profit and business sectors at national and international levels. The paper details key elements of the Body Project that facilitated partnership development, dissemination and implementation, including use of community-based participatory research methods and a blended train-the-trainer and task-shifting approach. We observed consistent themes across partnerships, including: sharing decision making with community partners, engaging of community leaders as gatekeepers, emphasizing strengths of community partners, working within the community's structure, optimizing non-traditional and/or private financial resources, placing value on cost-effectiveness and sustainability, marketing the program, and supporting flexibility and creativity in developing strategies for evolution within the community and in research. Ideally, lessons learned with the Body Project can be generalized to implementation of other body image and eating disorder prevention programs.

    Depth images have advantages of simple processing, fog penetration, and little affection by light, thus a body shape detection algorithm based on depth image was proposed to judge personnel evacuation. This study started by making body shape dataset using a depth sensor, then extracting the HOG-depth feature. The best parameters were found, including the range of gradient direction and the number of bins. Next step was to train and classify the body shape dataset using different classifiers, and gentle Adaboost algorithm based on CART weak classifiers got the best result. Then we discussed the effect of traversal method of sliding window, and found a better pixel number of every moving step. At last, the intellectualized control method under actual personnel evacuating situation was completed from the view of software implementation.

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

    2010-06-01

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

  10. Reversal of a body image disorder (macrosomatognosia) in Parkinson's disease by treatment with AC pulsed electromagnetic fields.

    Macrosomatognosia refers to a disorder of the body image in which the patient perceives a part or parts of his body as disproportionately large. Macrosomatognosia has been associated with lesions in the parietal lobe, particularly the right parietal lobe, which integrates perceptual-sensorimotor functions concerned with the body image. It has been observed most commonly in patients with paroxysmal cerebral disorders such as epilepsy and migraine. The Draw-a-Person-Test has been employed in neuropsychological testing to identify disorders of the body image. Three fully medicated elderly Parkinsonian patients who exhibited, on the Draw-a-Person Test, macrosomatognosia involving the upper limbs are presented. In these patients spontaneous drawing of the figure of a man demonstrated disproportionately large arms. Furthermore, it was observed that the arm affected by tremor or, in the case of bilateral tremor, the arm showing the most severe tremor showed the greatest abnormality. This association implies that dopaminergic mechanisms influence neuronal systems in the nondominant right parietal lobe which construct the body image. After receiving a course of treatments with AC pulsed electromagnetic fields (EMFs) in the picotesla flux density applied transcranially, these patients' drawings showed reversal of the macrosomatognosia. These findings demonstrate that transcranial applications of AC pulsed EMFs affect the neuronal systems involved in the construction of the human body image and additionally reverse disorders of the body image in Parkinsonism which are related to right parietal lobe dysfunction.

    The EXPLORER project aims to build a 2 meter long total-body PET scanner, which will provide extremely high sensitivity for imaging the entire human body. It will possess a range of capabilities currently unavailable to state-of-the-art clinical PET scanners with a limited axial field-of-view. The huge number of lines-of-response (LORs) of the EXPLORER poses a challenge to the data handling and image reconstruction. The objective of this study is to develop a quantitative image reconstruction method for the EXPLORER and compare its performance with current whole-body scanners. Fully 3D image reconstruction was performed using time-of-flight list-mode data with parallel computation. To recover the resolution loss caused by the parallax error between crystal pairs at a large axial ring difference or transaxial radial offset, we applied an image domain resolution model estimated from point source data. To evaluate the image quality, we conducted computer simulations using the SimSET Monte-Carlo toolkit and XCAT 2.0 anthropomorphic phantom to mimic a 20 min whole-body PET scan with an injection of 25 MBq (18)F-FDG. We compare the performance of the EXPLORER with a current clinical scanner that has an axial FOV of 22 cm. The comparison results demonstrated superior image quality from the EXPLORER with a 6.9-fold reduction in noise standard deviation comparing with multi-bed imaging using the clinical scanner.

    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.

    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.

    A slight frame and poor appetite are common among patients with cystic fibrosis (CF) yet healthy body weight has been related to a better prognosis. A review of studies exploring body image (BI) among adults and adolescents with CF was conducted. Seven electronic databases were searched for potential papers. They located 128 references, of which 24 were read in full and 12 included in the review. Accepted papers suggested females with CF had a better BI compared to males, but this could compromise survival, given their preference for a low body weight. Males may be more motivated to adhere to nutritional advice because they favor a larger form. Practitioners should broach the topic of BI at clinic appointments to ensure this does not have a detrimental impact on self-management, although more research is required to guide professionals in this task.

    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.

    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

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

    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.

    2013-09-01

    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.

    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.

  5. Abnormalities in visual processing amongst students with body image concerns

    2014-01-01

    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.

    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.

    The purpose of this study was to evaluate the psychological repercussions of transition out of elite sport from a bodily point of view. We hypothesized that the passage from a bodily over-investment to a more sedentary state would have an effect on body satisfaction. 16 Transitioning Athletes following the Sydney Olympic Games were compared with 16 Active Athletes two times during the transition period using the Body-Image Questionnaire of Bruchon-Schweitzer. Qualitative data in the form of interviews provided a complement to the quantitative data. Analysis yielded no significant differences 1 1/2 mo. after career termination between the two groups but showed a decrease in body satisfaction between 1 1/2 and 5 mo. after career termination for Transitioning Athletes, with a significant between-group difference at 5 mo. The Transitioning Athletes initially reported weight gain and uncertainty about their real physical capacities but also a continued social recognition that maintained body satisfaction. Over time, however, they were increasingly aware of this bodily deterioration, as ongoing exercise served as a reality test. Added to this were perceived decreases in social value as well as disturbing somatic manifestations. The result was a substantial effect on body satisfaction.

    Sociocultural theory and social comparison theory were used to account for variations in body-image evaluation and body-image investment among male and female adolescents (N = 1,543). Exposure to magazines and television programs containing idealistic body imagery as well as frequency of self-comparison to universalistic targets (e.g., fashion models) were measured. Results provided minimal support for sociocultural theory, but fairly strong support for social comparison theory. Specifically, the extent to which males engaged in universalistic social comparison predicted appearance self-esteem, number of diets to gain weight, use of pathogenic weight control practices, and use of steroids to increase muscle mass. For females, universalistic social comparison predicted appearance self-esteem, body dissatisfaction, number of diets to lose weight, and use of pathogenic weight control practices. The possibility that the null effects for sociocultural theory were an artifact of dummy coding for missing data or theoretical interdependence were explored, but did not appear to be valid. Limitations of the present study and directions for future research are outlined.

    Transgene expression in intact animals now can be visualized by noninvasive techniques. However, the instruments and protocols developed so far have been formidable and expensive. We describe here a system for rapidly visualizing transgene expression in major organs of intact live mice that is simple, rapid, and eminently affordable. Green fluorescent protein (GFP) is expressed in the cells of brain, liver, pancreas, prostate, and bone, and its fluorescence is encoded in whole-body optical images. For low-magnification images, animals are illuminated atop a fluorescence light box and directly viewed with a thermoelectrically cooled color charge-coupled device camera. Higher-magnification images are made with the camera focused through an epi-fluorescence dissecting microscope. Both nude and normal mice were labeled by directly injecting 8 × 1010 plaque-forming units/ml of adenoviral GFP in 20–100 μl PBS and 10% glycerol into either the brain, liver, pancreas, prostate, or bone marrow. Within 5–8 h after adenoviral GFP injection, the fluorescence of the expressed GFP in brain and liver became visible, and whole-body images were recorded at video rates. The GFP fluorescence continued to increase for at least 12 h and remained detectable in liver for up to 4 months. The system's rapidity of image acquisition makes it capable of real-time recording. It requires neither exogenous contrast agents, radioactive substrates, nor long processing times. The method requires only that the expressed gene or promoter be fused or operatively linked to GFP. A comparatively modest investment allows the study of the therapeutic and diagnostic potential of suitably tagged genes in relatively opaque organisms. PMID:11050247

    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.

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

    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.

    Paediatric age group is most vulnerable for the accidental foreign body (FB) ingestion which may go unnoticed. These patients present with symptoms or complications as a result of FB and may mimic other conditions on various investigations. We describe a 9-month old infant who ingested crystal gel ball and presented with vomiting for a month. On radiological imaging it was interpreted as duplication cyst of the duodenum. At operation, crystal gel ball was retrieved. Our case vindicates importance of keeping various possibilities in mind as differential diagnoses during evaluation and management of surgical ailments such as the duplication cyst of duodenum.

    Practitioners in mental health care have long utilized the work of Hildegard Peplau, both for nursing discourse and for practice. At a time when the role of theory in practice is once more being debated, and when theories are being applied in new contexts, this paper examines the contribution that Peplau's work may have to offer altered body image nursing care. A case study is used to highlight concepts in practice, the paper examining the ways in which Peplau's Theory of Interpersonal Relations complement the other elements of practice knowledge that the nurse uses to assist patients and lay carers alike.

    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.

    The purpose of this study was to examine the acute affective responses of high and low body satisfied (BS) men who viewed physique slides of the male ideal (model-slides), physique slides of themselves (self-slides), and nonphysique slides (control-slides). During three laboratory visits the participants viewed the slides from one of the three conditions, and they completed pre-, in-, and post-task affective measures. It was found that the: (a) high BS group reported less mood disturbance than the low BS group; (b) participants reported an increase in depression, anger, and body dissatisfaction after viewing the self-slides; (c) participants indicated a decrease in body dissatisfaction after viewing the model-slides; and (d) viewing the control-slides did not result in affective changes. Findings suggest that viewing physique slides results in increased mood disturbance, regardless of BS level.

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

    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.

    A key question in diffusion imaging is how many diffusion-weighted images suffice to provide adequate signal-to-noise ratio (SNR) for studies of fiber integrity. Motion, physiological effects, and scan duration all affect the achievable SNR in real brain images, making theoretical studies and simulations only partially useful. We therefore scanned 50 healthy adults with 105-gradient high-angular resolution diffusion imaging (HARDI) at 4 Tesla. From gradient image subsets of varying size (6≤N≤94) that optimized a spherical angular distribution energy, we created SNR plots (versus gradient numbers) for seven common diffusion anisotropy indices: fractional and relative anisotropy (FA, RA), mean diffusivity (MD), volume ratio (VR), geodesic anisotropy (GA), its hyperbolic tangent (tGA), and generalized fractional anisotropy (GFA). SNR, defined in a region of interest in the corpus callosum, was near-maximal with 58, 66 and 62 gradients for MD, FA and RA in respectively, and with about 55 gradients for GA and tGA. For VR and GFA, SNR increased rapidly with more gradients. SNR was optimized when the ratio of diffusion-sensitized to non-sensitized images was 9.13 for GA and tGA, 10.57 for FA, 9.17 for RA, and 26 for MD and VR. In orientation density functions modeling the HARDI signal as a continuous mixture of tensors, the diffusion profile reconstruction accuracy rose rapidly with additional gradients. These plots may help in making trade-off decisions when designing diffusion imaging protocols. PMID:19819339

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

    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.

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

    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.

    A whole-body PET/CT scan extending from the vertex of the head to the toes of the patient is not feasible on a number of commercially available PET/CT scanners due to a limitation in the extent of bed travel on these systems. In such cases, the PET scan has to be divided into two parts: one covering the upper body segment, while the other covering the lower body segment. The aim of this paper is to describe and evaluate, using phantom and patient studies, a software tool that was developed to stitch two body segments and output a single whole-body image set, thereby facilitating the interpretation of whole-body PET scans. A mathematical model was first developed to stitch images from two body segments using three landmarks. The model calculates the relative positions of the landmarks on the two segments and then generates a rigid transformation that aligns these landmarks on the two segments. A software tool was written to implement this model while correcting for radioactive decay between the two body segments, and output a single DICOM whole-body image set with all the necessary tags. One phantom, and six patient studies were conducted to evaluate the performance of the software. In these studies, six radio-opaque markers (BBs) were used as landmarks (three on each leg). All studies were acquired in two body segments with BBs placed in the overlap region of the two segments. The PET/CT images of each segment were then stitched using the software tool to create a single DICOM whole-body PET/CT image. Evaluation of the stitching tool was based on visual inspection, consistency of radiotracer uptake in the two segments, and ability to display the resultant DICOM image set on two independent workstations. The software tool successfully stitched the two segments of the phantom image, and generated a single whole-body DICOM PET/CT image set that had the correct alignment and activity concentration throughout the image. The stitched images were viewed by two independent

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

    Burn injury deformities and obesity have been associated with social integration difficulty and body image dissatisfaction. However, the combined effects of obesity and burn injury on social integration difficulty and body image dissatisfaction are unknown. Adolescent and young adult burn injury survivors were categorized as normal weight (n = 47) or overweight and obese (n = 21). Burn-related and anthropometric information were obtained from patients' medical records, and validated questionnaires were used to assess the main outcomes and possible confounders. Analysis of covariance and multiple linear regressions were performed to evaluate the objectives of this study. Obese and overweight burn injury survivors did not experience increased body image dissatisfaction (12 ± 4.3 vs 13.1 ± 4.4; P = .57) or social integration difficulty (17.5 ± 6.9 vs 15.5 ± 5.7; P = .16) compared with normal weight burn injury survivors. Weight status was not a significant predictor of social integration difficulty or body image dissatisfaction (P = .19 and P = .24, respectively). However, mobility limitations predicted greater social integration difficulty (P = .005) and body image dissatisfaction (P < .001), whereas higher weight status at burn was a borderline significant predictor of body image dissatisfaction (P = .05). Obese and overweight adolescents and young adults, who sustained major burn injury as children, do not experience greater social integration difficulty and body image dissatisfaction compared with normal weight burn injury survivors. Mobility limitations and higher weight status at burn are likely more important factors affecting the long-term social integration difficulty and body image dissatisfaction of these young people.

    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.

    Although research addressing body size misperception has focused on socio-cognitive processes, such as internalization of the "ideal" images of bodies in the media, the perceptual basis of this phenomenon remains largely unknown. Further, most studies focus on body size per se even though this depends on both fat and muscle mass - variables that have very different relationships with health. We tested visual adaptation as a mechanism for inducing body fat and muscle mass misperception, and assessed whether these two dimensions of body space are processed independently. Observers manipulated the apparent fat and muscle mass of bodies to make them appear "normal" before and after inspecting images from one of four adaptation conditions (increased fat/decreased fat/increased muscle/decreased muscle). Exposure resulted in a shift in the point of subjective normality in the direction of the adapting images along the relevant (fat or muscle) axis, suggesting that the neural mechanisms involved in body fat and muscle perception are independent. This supports the viability of adaptation as a model of real-world body size misperception, and extends its applicability to clinical manifestations of body image disturbance that entail not only preoccupation with thinness (e.g., anorexia nervosa) but also with muscularity (e.g., muscle dysmorphia).

  19. RF Device for Acquiring Images of the Human Body

    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

    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.

    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

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

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

    2016-07-04

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

    2010-09-01

    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.

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

    Corner, Brian D.; Hu, Anmin

    1998-03-01

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

    2016-01-01

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

    2016-09-01

    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.

    Disclaimer labels on airbrushed media images have generated political attention and advocacy as a social policy approach to promoting positive body image. Experimental research suggests that labelling is ineffective and consumers' viewpoints have been overlooked. A mixed-method study explored British consumers' (N = 1555, aged 11-78 years) opinions on body image and social policy approaches. Thematic analysis indicated scepticism about the effectiveness of labelling images. Quantitatively, adults, although not adolescents, reported that labelling was unlikely to improve body image. Appearance diversity in media and reorienting social norms from appearance to function and health were perceived as effective strategies. Social policy and research implications are discussed.

    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.

    2014-01-01

    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.

    2016-06-01

    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.

    Introduction We describe a prototype positron projection imager (PPI) for visualizing the whole-body biodistribution of positron-emitting compounds in mouse-size animals. The final version of the PPI will be integrated into the MONICA portable dual-gamma camera system to allow the user to interchangeably image either single photon or positron-emitting compounds in a shared software and hardware environment. Methods A mouse is placed in the mid-plane between two identical, opposed, pixelated LYSO arrays separated by 21.8-cm and in time coincidence. An image of the distribution of positron decays in the animal is formed on this mid-plane by coincidence events that fall within a small cone angle to the perpendicular to the two detectors and within a user-specified energy window. We measured the imaging performance of this device with phantoms and in tests performed in mice injected with various compounds labeled with positron-emitting isotopes. Results Representative performance measurements yielded the following results (energy window 250–650 keV, cone angle 3.5-degrees): resolution in the image mid-plane, 1.66-mm (FWHM), resolution ±1.5-cm above and below the image plane, 2.2-mm (FWHM), sensitivity: 0.237-cps/kBq (8.76-cps/μCi) 18F (0.024% absolute). Energy resolution was 15.9% with a linear-count-rate operating range of 0–14.8 MBq (0–400 μCi) and a corrected sensitivity variation across the field-of-view of <3%. Whole-body distributions of [18F] FDG and [18F] fluoride were well visualized in mice of typical size. Conclusion Performance measurements and field studies indicate that the PPI is well suited to whole-body positron projection imaging of mice. When integrated into the MONICA gamma camera system, the PPI may be particularly useful early in the drug development cycle where, like MONICA, basic whole-body biodistribution data can direct future development of the agent under study and where logistical factors (e.g., available imaging space, non

    2016-11-25

    This study evaluated the impact on young women's body satisfaction of an advertising campaign: Aerie Real, which included images of models who were not digitally modified. In total, 200 female students were randomly allocated to view either Aerie Real images or digitally modified images from previous campaigns. In the total sample, no condition differences appeared. However, participants with high appearance comparison reported a smaller decrease in body satisfaction after viewing the Aerie Real images as compared to those viewing previous images (p = .003). Findings provide preliminary support for the Aerie Real campaign as less deleterious form of media for body image.

    2014-01-01

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

    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.

    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.

    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

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

  9. 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

    Body dysmorphic disorder falls under the category of obsessive-compulsive and related disorders, yet research has suggested it may also be highly associated with social anxiety disorder. The current study examined body image variables among 68 outpatients with primary obsessive-compulsive disorder (OCD; n=22), social anxiety disorder (SAD; n=25), and panic disorder (PD; n=21). Participants filled out self-report measures of body image disturbance, attitudes toward one's appearance, and anxiety. Body image disturbance and attitudes toward appearance did not significantly differ between the groups. However, SAD symptoms predicted body image disturbance, Appearance Evaluation and Body Areas Satisfaction, and OCD symptoms predicted Appearance Orientation. These findings suggest that SAD and OCD may be associated with different facets of body image. Implications for the treatment of anxiety disorders and for future research are discussed.

    2010-01-01

    Research has linked an appearance-focused family culture (including parental commentary about weight/size) with increased disordered eating and body image dissatisfaction in daughters. Since body image dissatisfaction is also a risk factor for disordered eating, body image dissatisfaction may contribute to the link between family focus on appearance and disordered eating. This correlational study included a sample of 268 college women who completed the Family Influence Scale, Bulimia Test - Revised, Body Shape Questionnaire, and a series of items about their parents' comments about their weight/size. Both family appearance focus and daughters' body image dissatisfaction predicted increased disordered eating in daughters. Additionally, body image dissatisfaction partially mediated the influence of family appearance focus on daughters' disordered eating. No specific type of parental comments regarding weight/size emerged as a superior predictor of eating disturbance, but encouragement to control weight/size was a stronger predictor of body dissatisfaction than other types of parental comments.

    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.

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

    2014-03-01

    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.

    2013-09-01

    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.

    Background. The State of Kuwait has a growing obesity epidemic in both genders and all age groups; however, obesity rates in the young seem to be rising. Methods. We conducted a cross-sectional survey in 169 Kuwaiti female adolescents attending both private and public schools spanning the six governorates in the State of Kuwait in order to explore female adolescents' self-image, body dissatisfaction, type of school (private versus public), TV viewing, and computer games and their relationship to body mass index. Results. Approximately half the students classified as obese perceived their body image to lie in the normal range. Females in the obese category were the most dissatisfied with their body image, followed by those in the overweight category. Eating behavior, level of physical activity, school type, television viewing, computer/video usage, and desired BMI were not significantly associated with level of obesity. Conclusion. This study was one of the few studies to assess adolescent females' body image dissatisfaction in relation to obesity in the State of Kuwait. The results suggest that including body image dissatisfaction awareness into obesity prevention programs would be of value.

    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 main objective of this study was to determine to which extent body mass index and position of impacted lower third molar was affecting the pain intensity in the first seven postoperative days. The study was conducted following the extraction of the lower third molar in 108 patients. Depending on the type of information given to each particular patient, the patients were divided in two groups: the test group where patients were given detailed standard written and verbal instructions and the control group which received only standard written instructions about treatment after surgery. Using canonical discriminant analysis we investigated the influence of body mass index and the position of impacted lower third molar on postoperative pain intensity in two groups of patients. Results of this study showed that the body mass index or the tooth position did not have influence on intensity of postoperative pain. The body mass index and the position of impacted lower third molar do not affect the postoperative pain intensity.

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

    We investigated body image in St. Kitts, a Caribbean island where tourism, international media, and relatively high levels of body fat are common. Participants were men and women recruited from St. Kitts (n = 39) and, for comparison, U.S. samples from universities (n = 618) and the Internet (n = 438). Participants were shown computer generated images varying in apparent body fat level and muscularity or breast size and they indicated their body type preferences and attitudes. Overall, there were only modest differences in body type preferences between St. Kitts and the Internet sample, with the St. Kitts participants being somewhat more likely to value heavier women. Notably, however, men and women from St. Kitts were more likely to idealize smaller breasts than participants in the U.S. samples. Attitudes regarding muscularity were generally similar across samples. This study provides one of the few investigations of body preferences in the Caribbean.

    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

    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.

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

    PubMed Central

    Westbury, Chris F.; Cribben, Ivor; Cummine, Jacqueline

    2016-01-01

    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.

    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.

    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.

    The article aims to verify body image perception and associated factors among elderly individuals in Campina Grande, State of Paraiba. It involves a cross-sectional, population and home-based study, with individuals 60 years or older of both sexes. Body image perception was considered the dependent variable for purposes of analysis and study of possible associations. The independent variables were: age group, nutritional status, number of diseases, health perception and regular practice of physical activities. To identify associated factors, univariate and multivariate regression analyses were carried out using SPSS 17.0 software. Overall, 806 elderly individuals were interviewed. Men showed greater satisfaction with body image when compared to women and older participants were more satisfied than younger participants. Among the factors related to dissatisfaction in women, underweight and overweight/obesity were associated with an increased risk of dissatisfaction. Among men, older age constituted a protective factor for dissatisfaction, while underweight and overweight/obesity were risk factors for dissatisfaction. The results of this study suggest a possible influence of nutritional status on body image perception among the elderly, negatively affecting their perception of body image.

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

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

    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.

  13. Oesophageal foreign bodies in dogs: factors affecting success of endoscopic retrieval

    2010-01-01

    Oesophageal foreign bodies are common in dogs. Endoscopic removal is a viable treatment option but few studies have assessed the clinical and radiographic features that would be useful in decision-making and prognosis. Dogs (n = 44) with oesophageal foreign bodies presented to the University Veterinary Hospital were assessed. Terriers and West Highland White Terriers were significantly overrepresented (p < 0.0001) and in those breeds the foreign body was significantly (p < 0.0001) more likely to be located caudal to the heart base. The majority (88.6%) of foreign bodies were bones or bone fragments. Group 1 (n = 30) included animals where endoscopic removal was successful and Group 2 (n = 14) animals where it was unsuccessful or not attempted because of evidence of oesophageal rupture. There was no statistically significant difference in age, sex, body weight, type, location and size of foreign body, recovery rate, short-term complications and long-term outcome between the two groups. Duration of signs prior to presentation and time to spontaneous oral feeding were significantly longer (p < 0.01 in each case) in Group 2 (five days and 120 hours, respectively) compared to Group 1 (2 days and 24 hours, respectively). Mortality was 11.1%. Long-term follow-up of 29 dogs suggested oesophageal stricture formation manageable by feeding alone in seven (24.1%) cases. Terriers appear predisposed to oesophageal foreign bodies. Success of endoscopic removal is adversely affected by duration of signs prior to presentation. Surgical removal negatively influences time to recovery. Stricture formation appears to be a relatively common complication and alternate measures for its prevention should be sought. PMID:21851744

    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.

  16. Assessment methods for eating disorders and body image disorders.

    2010-12-01

    The growing interest in the treatment and research of eating disorders has stimulated the development of assessment methods, and there are now many questionnaires for evaluating behavioral and attitudinal characteristics of eating pathology. The present article sets out to review the assessment tools that are widely used in clinical practice and research. In particular, it covers self-report measures with summaries of their psychometric properties. It also presents diagnostic questionnaires based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria. The instruments described include screening questionnaires, measurement tools for specific eating disorder symptoms, measurement of quality of life in eating disorders, and some tools for the measurement of body image disorder, a common feature of eating disorders. There is also a discussion of distorting factors that decrease the authenticity of assessment tools. These problems arise from the definition of some constructs and from the phenomena of denial and concealment, which are frequent among eating-disordered individuals. The frequent co-occurrence of other psychopathological features (e.g., multiimpulsive symptoms) shows that other psychological phenomena should also be evaluated in line with the assessment of eating disorders.

    The study aimed to test the Embodiment Model of Positive Body Image (Menzel & Levine, 2011) within the context of yoga. 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.

    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.

    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.

    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.

    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.

    Purpose: Whole-body positron emission tomography/computed tomography (PET/CT) has become a standard method of imaging patients with various disease conditions, especially cancer. Body-wide accurate quantification of disease burden in PET/CT images is important for characterizing lesions, staging disease, prognosticating patient outcome, planning treatment, and evaluating disease response to therapeutic interventions. However, body-wide anatomy recognition in PET/CT is a critical first step for accurately and automatically quantifying disease body-wide, body-region-wise, and organwise. This latter process, however, has remained a challenge due to the lower quality of the anatomic information portrayed in the CT component of this imaging modality and the paucity of anatomic details in the PET component. In this paper, the authors demonstrate the adaptation of a recently developed automatic anatomy recognition (AAR) methodology [Udupa et al., “Body-wide hierarchical fuzzy modeling, recognition, and delineation of anatomy in medical images,” Med. Image Anal. 18, 752–771 (2014)] to PET/CT images. Their goal was to test what level of object localization accuracy can be achieved on PET/CT compared to that achieved on diagnostic CT images. Methods: The authors advance the AAR approach in this work in three fronts: (i) from body-region-wise treatment in the work of Udupa et al. to whole body; (ii) from the use of image intensity in optimal object recognition in the work of Udupa et al. to intensity plus object-specific texture properties, and (iii) from the intramodality model-building-recognition strategy to the intermodality approach. The whole-body approach allows consideration of relationships among objects in different body regions, which was previously not possible. Consideration of object texture allows generalizing the previous optimal threshold-based fuzzy model recognition method from intensity images to any derived fuzzy membership image, and in the process

    To 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

  4. Facial affective reactions to bitter-tasting foods and body mass index in adults.

    Differences in food consumption among body-weight statuses (e.g., higher fruit intake linked with lower body mass index (BMI) and energy-dense products with higher BMI) has raised the question of why people who are overweight or are at risk of becoming overweight eat differently from thinner people. One explanation, in terms of sensitivity to affective properties of food, suggests that palatability-driven consumption is likely to be an important contributor to food intake, and therefore body weight. Extending this approach to unpalatable tastes, we examined the relationship between aversive reactions to foods and BMI. We hypothesized that people who have a high BMI will show more negative affective reactions to bitter-tasting stimuli, even after controlling for sensory perception differences. Given that hedonic reactions may influence consumption even without conscious feelings of pleasure/displeasure, the facial expressions were included in order to provide more direct access to affective systems than subjective reports. Forty adults (28 females, 12 males) participated voluntarily. Their ages ranged from 18 to 46 years (M=24.2, SD=5.8). On the basis of BMI, participants were classified as low BMI (BMI<20; n=20) and high BMI (BMI>23; n=20). The mean BMI was 19.1 for low BMI (SD=0.7) and 25.2 for high BMI participants (SD=1.8). Each subject tasted 5 mL of a grapefruit juice drink and a bitter chocolate drink. Subjects rated the drinks' hedonic and incentive value, familiarity and bitter intensity immediately after each stimulus presentation. The results indicated that high BMI participants reacted to bitter stimuli showing more profound changes from baseline in neutral and disgust facial expressions compared with low BMI. No differences between groups were detected for the subjective pleasantness and familiarity. The research here is the first to examine how affective facial reactions to bitter food, apart from taste responsiveness, can predict differences in BMI.

    Background: Creation of an ostomy leads to significant change in the body image of the patient. However, adaptation to this alteration of body image is necessary for rehabilitation following surgery. The objective of this study was to identify the factors that influence adaptation to altered body image. Materials and Methods: An analytical cross-sectional study was conducted among 41 ostomy patients who were treated at a single tertiary care unit. Body image disturbance questionnaire (BIDQ) was used to assess the perception of body image. Data were analyzed using independent samples t-test (unpaired), Chi-square test, and Spearman's correlation. Results: In our study, the mean BIDQ score was 2.22 (standard deviation ± 0.88). The body image disturbance was significantly associated with younger age (P < 0.05). The prevalence of body image disturbance was significantly higher among overweight patients (P < 0.05). Males had a higher BIDQ score than females. Those who had temporary stoma had significantly higher BIDQ score (P < 0.05). Those who felt depressed or had thoughts of self-harm soon after surgery had significantly high body image disturbance score (P < 0.05). There was a significant negative correlation with the perception of self-efficacy and body image disturbance (P < 0.01). There was no significant association between body image disturbance and the diagnosis, type of surgery, or time duration after surgery. Conclusions: Poor adaptation to alteration of body image was associated with younger age, overweight, and temporary stoma. Individuals at risk of poor adaptation should be identified before surgery and counseled before surgery, after surgery, and during follow-up visits. PMID:28250561

    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.

  8. Quinine controls body weight gain without affecting food intake in male C57BL6 mice

    PubMed Central

    2013-01-01

    Background Quinine is a natural molecule commonly used as a flavouring agent in tonic water. Diet supplementation with quinine leads to decreased body weight and food intake in rats. Quinine is an in vitro inhibitor of Trpm5, a cation channel expressed in taste bud cells, the gastrointestinal tract and pancreas. The objective of this work is to determine the effect of diet supplementation with quinine on body weight and body composition in male mice, to investigate its mechanism of action, and whether the effect is mediated through Trpm5. Results Compared with mice consuming AIN, a regular balanced diet, mice consuming AIN diet supplemented with 0.1% quinine gained less weight (2.89 ± 0.30 g vs 5.39 ± 0.50 g) and less fat mass (2.22 ± 0.26 g vs 4.33 ± 0.43 g) after 13 weeks of diet, and had lower blood glucose and plasma triglycerides. There was no difference in food intake between the mice consuming quinine supplemented diet and those consuming control diet. Trpm5 knockout mice gained less fat mass than wild-type mice. There was a trend for a diet-genotype interaction for body weight and body weight gain, with the effect of quinine less pronounced in the Trpm5 KO than in the WT background. Faecal weight, energy and lipid contents were higher in quinine fed mice compared to regular AIN fed mice and in Trpm5 KO mice compared to wild type mice. Conclusion Quinine contributes to weight control in male C57BL6 mice without affecting food intake. A partial contribution of Trpm5 to quinine dependent body weight control is suggested.

    Diffusion-weighted whole-body imaging with background body signal suppression/T2 image fusion (DWIBS/T2) is useful for the diagnosis of cancer as it presents a clear contrast between cancerous and non-cancerous tissue. The present study investigated the limitations and advantages of DWIBS/T2 with regards to the diagnosis of colorectal polyp (CP) or cancer (CRC). The current study included patients diagnosed with CP or CRC following colonoscopy, who were subjected to DWIBS/T2 between July 2012 and March 2015. Patient records were analyzed retrospectively. Patients were subjected to DWIBS/T2 when they presented with abdominal cancers or inflammation. Colonoscopy was performed as part of screening, or if patients had suspected colon cancer or inflammatory bowel disease. A total of 8 male and 7 female patients were enrolled in the present study. All patients, with the exception of one who had been diagnosed with CRC following colonoscopy, had positive results and all patients diagnosed with CP following a colonoscopy, with the exception of one, had negative results on DWIBS/T2. Thus, CRC was detected by DWIBS/T2, while CP was not (P=0.0028). The diameter of CRC lesions was significantly larger than that of CP (P<0.0001) and that of lesions positive on DWIBS/T2 was significantly larger than that of negative lesions (P=0.0004). The depth of invasion tended to be greater for lesions positive on DWIBS/T2 compared with that of negative ones. This indicated that DWIBS/T2 may be suitable for the detection of CRC but not for detection of CP. The results of DWIBS/T2 may also be affected by lesion diameter and depth of invasion.

    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

  12. A delay in pubertal onset affects the covariation of body weight, estradiol, and bone size.

    2009-04-01

    The skeletal system functions as a locomotive organ and a mineral reservoir and combinations of genetic and environmental factors affect the skeletal system. Although delayed puberty is associated with compromised bone mass, suppression of estrogen should be beneficial to cortical strength. The purpose was to employ path analysis to study bone strength and delayed puberty. Forty-five female rats were randomly assigned to a control group (n = 15) and an experimental group (n = 30) that received injections of gonadotropin releasing hormone antagonist (GnRH-a). Causal models were constructed by specifying directed paths between bone traits. The first model tested the hypothesis that the functional relationships between bone traits and body weight were altered by a delay in pubertal onset. GnRH-a injections during puberty altered the covariation between body weight and bone size. The second model was constructed to test the hypothesis that variability in stiffness was causally related to variability in body weight. The model also tested the relationship between the periosteal and endocortical surfaces and their relationship to stiffness. There was no change in the relationship between the surfaces in the GnRH-a group. The third model determined the effect of estradiol on both total area and relative cortical area in both groups. The relationship between periosteal surface and serum estradiol levels was only significant during estrogen suppression. These data suggest that increases in body weight during or prior to puberty may not be protective of bone strength.

    The aim of this study was to determine how muscle activity and body orientation contribute to the triceps surae spinal transmission modulation, when moving from a sitting to a standing position. Maximal Hoffmann-reflex (Hmax) and motor potential (Mmax) were evoked in the soleus (SOL), medial and lateral gastrocnemius in 10 male subjects and in three conditions, passive sitting, active sitting and upright standing, with the same SOL activity in active sitting and upright standing. Moreover volitional wave (V) was evoked in the two active conditions (i.e., active sitting and upright standing). The results showed that SOL Hmax/Mmax was lower in active sitting than in passive sitting, while for the gastrocnemii it was not significantly altered. For the three plantar flexors, Hmax/Mmax was lower in upright standing than in active sitting, whereas V/Mmax was not modulated. SOL H-reflex is therefore affected by the increase in muscle activity and change in body orientation, while, in the gastrocnemii, it was only affected by a change in posture. In conclusion, passing from a sitting to a standing position affects the Hmax/Mmax of the whole triceps surae, but the mechanisms responsible for this change differ among the synergist muscles. The V/Mmax does not change when upright stance is assumed. This means that the increased inhibitory activity in orthostatic position is compensated by an increased excitatory inflow to the α-motoneurons of central and/or peripheral origin.

    This study was performed to investigate the effects of behavior modification on body image, depression and body fat in obese elementary school children. Sixty-two elementary students of the 4th to 6th grade were selected from two different Seoul schools. Thirty-four children in one school were designated as the experimental group, and 28 children from the other school as the control group. The experimental group received 60 - 70 minutes of behavior modification, once a week, for 8 weeks. The control group received neither management nor treatment. The results indicated a significant improvement of body image and a reduction in the increase rate of body fat for the experimental group. This finding strongly supports the theory that behavior modification can be used as an effective strategy in the treatment of obese children.

  15. On the use of trace-weighted images in body diffusional kurtosis imaging.

    PubMed

    Giannelli, Marco; Toschi, Nicola

    2016-05-01

    Diffusional kurtosis imaging (DKI) has proven to be a promising diffusion-MRI technique whose first and most established applications are in neuroimaging. Recently, a number of preliminary studies have assessed the feasibility and potential usefulness of DKI in extra-cranial regions such as prostate, liver, kidney, bladder and breast. The stringent time constraints in most routine body MRI exams frequently mandate the acquisition of diffusion-weighted images (DWIs) with (only) three diffusion weighting directions (i.e. the main orthogonal directions). The aim of this study was to evaluate the potential error introduced in the estimation of the average of the three directional diffusional kurtosis values (K) by using, for each b-value, the geometric mean (trace-weighted image) of acquired DWIs (as is common practice in most diffusion-MRI studies of the body) instead of fitting the DKI model to DWIs acquired along each direction prior to averaging. By solving the DKI model analytically while imposing three orthogonal diffusion weighting directions and two non-null b-values (800 and 2000s/mm(2)), extensive simulations were performed for different K values (0-3) and a wide range of diffusion anisotropy values. The error in the estimates of K induced by geometrical averaging of DWIs was assessed and compared to the uncertainty in K caused by DWIs noise for low (20), medium (40) and high (80) signal-to-noise ratio (SNR) values. The simulations showed that geometrical averaging of the DWIs introduces a noticeable error in estimated K. While the error in K varies non-monotonically with K and with the degree of diffusion anisotropy, there is a trend of increasing absolute error with both increasing K and increasing degree of diffusion anisotropy. In particular, for values of K close to 1 and low/moderate (0-0.4) diffusion anisotropy degrees (typical of various body tissues), the absolute error in K can range up to 60% of K. In this case, at all SNR values (20, 40, 80), the

    Breast cancer patients encounter body image changes throughout their diagnosis, treatment, and recovery from breast cancer. No prospective studies were identified investigating communication between physicians and breast cancer patients related to body image. This qualitative pilot study determines (1) how breast cancer patients prefer their physicians communicate regarding body image changes and (2) how comfortable physicians are in discussing body image issues with their patients. Data were collected from patients over 12 weeks through the breast evaluation questionnaire (BEQ), a valid and reliable instrument, and a qualitative questionnaire. Ten physicians completed a qualitative questionnaire. The data were analyzed using frequency analysis. Nearly 70% of the patients reported there was more the physician could do to improve patient comfort in discussing breast-related body image concerns. Honesty, openness, and directness were important to the patients. Thirty-three percent of the patients answered that their physicians should be honest, open, and direct while discussing these issues. On a five-point Likert scale (1 = very uncomfortable and 5 = very comfortable), the physicians most frequently answered a 4 when asked how comfortable they are speaking about breast-related body image issues; however, only four out of 10 always address the topic themselves during the patient's visit. These data suggest that patients want honesty, openness, and directness from their physicians during the discussion of breast-related body image issues. The physicians report they are comfortable speaking about breast-related body image issues; yet, they do not directly initiate the topic.

    2016-05-01

    Whole-body MR imaging is being increasingly used in children to evaluate the extent of various oncologic and non-oncologic entities. The lack of exposure to ionizing radiation, excellent soft-tissue contrast (even without the use of contrast agents), and functional imaging capabilities make it especially suitable for screening and surveillance in the pediatric population. Technical developments such as moving table platforms, multi-channel/multi-element surface coils, and parallel imaging allow imaging of the entire body with multiple sequences in a reasonable 30- to 40-min time frame, which has facilitated its acceptance in routine clinical practice. The initial investigations in whole-body MR imaging were primarily focused on oncologic applications such as tumor screening and staging. The exquisite sensitivity of fluid-sensitive MR sequences to many different types of pathology has led to new applications of whole-body MR imaging in evaluation of multifocal rheumatologic conditions. Availability of blood pool contrast agents has allowed whole-body MR angiographic imaging of vascular malformations, vasculitides and vasculopathies. Whole-body MRI is being applied for delineating the extent and distribution of systemic and multifocal diseases, establishing diagnoses, assessing treatment response, and surveillance imaging. This article reviews the technique and clinical applications of whole-body MR imaging in children.

    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.

    2008-05-01

    This study investigates the influence of media exposure on body image state in eating-disordered (ED) patients. The attitudinal and perceptual components of body image are assessed, as well as any associations with dysfunctional cognitions and behavioral consequences. Twenty-five ED patients and 25 non-ED controls (ND) viewed commercials either featuring appearance (AC; 5 min) or not featuring appearance (NC; 5 min). Both perceptual and attitudinal body image components changed markedly after the AC condition for ED patients, compared with the ND group and NC condition. Cognitions referring to dietary restraint and internalization/social comparison also changed significantly in ED patients depending on the experimental manipulation, whereas thoughts about body and self-esteem did not. The results suggest that media exposure acts as a stimulus that triggers body-related schemas. Partial support is given to cognitive-behavioral models of eating disorders, which postulate an association between cognitive bias, body image disturbances, and compensatory behavioral consequences.

    diller scofidio + renfro's Brasserie restaurant sets the scene for this article's overarching question: what are the stakes of absorbing "the washroom" into our affective habits as trans people? 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.

    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

    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.

    2015-03-01

    A substantial body of research documents that exposure to images depicting a "thin ideal" body figure effects women's state-oriented body satisfaction. However, there is evidence that the societal ideal body figure of females is evolving to be not just thin, but also muscular or toned. Therefore, the purpose of this research was to test the effect of exposure to ideal body figures that are both thin and muscular on female state body satisfaction. Researchers recruited female participants (N=366) from an online community (Amazon's Mechanical Turk) and randomly assigned them to view images in one of four conditions: thin, thin and muscular, thin and hypermuscular, and control (images of cars). Results indicated that state-oriented body satisfaction decreased in the thin condition and thin and muscular condition, but not the hypermuscular or control conditions. These findings have implications for clinical initiatives as well as future research.

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

    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.

    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.

    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.

    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.

    Variation in the timing of pubertal maturation may result in behavioral differences among early, mid-, and late maturers. Using data from the National Health Examination Survey, a national probability sample of children and youth aged 12-17, we investigated the relationships between maturational timing and body image, school behavior, and deviance. In terms of body image, the early maturing boys were the group most satisfied with height and weight. The early maturing girls were most dissatisfied with weight, with 69% wishing to be thinner. This great dissatisfaction with weight reported by early maturing girls is probably not an affect of early maturation, but a concomitant of maturation in general. The majority of girls became dissatisfied with their weight as they matured, and females from the higher social groups were more likely to want to be thinner than females from lower groups. Thus, a normal developmental process is being viewed negatively by females and positively by males. Male early maturers more often had deviant behavior, but there were no consistent findings for girls. There was no effect of maturational timing on teacher reports of school absence, adjustment, popularity, need for discipline, or grade repetition.

    2004-01-01

    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

    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.

    Background: Body-related teasing is known to be linked to body dissatisfaction and dieting behavior in adolescents. However, little is known about it in non-Western countries. This study aims to examine the prevalence of body-related teasing among Japanese adolescents and its connection to weight status, body image, and dieting behavior to consider implications for public health. Methods: The design of this study is a cross-sectional study. An anonymous self-administrated survey was conducted with 1172 junior high school students in Higashi-Osaka City in Osaka Prefecture in Japan. The sampling method was non-random design. The survey items included self-reported height and weight, history and source of teasing, body image perception, and dieting behavior. A chi-square test and logistic regression analysis were used to examine the associations. Results: A history of teasing was reported by 16.4% of boys and 32.5% of girls (P < 0.001, effect size = 0.19). The most common answer for source of teasing was friends (84.7% of boys’ teasing, 67.1% of girls’ teasing, P = 0.003, effect size = 0.19). Students who were overweight, of an upper-normal weight status, and perceived themselves as "fat" were at a greater risk of being teased. Additionally, students with a history of teasing were significantly likelier to display dieting behavior (odds ratios with confidence intervals: boys 4.06 [2.08–7.93], girls 2.40 [1.53– 3.75]). Conclusion: Body-related teasing has a significant association with body image and dieting behavior in Japanese adolescents. A school-based education should be provided to reduce body-related teasing.

    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

    This study investigated the effectiveness of a 6-week cognitive-behavioral group intervention in promoting the development of positive body image. The study also examined if, in accordance with the objectification theory, participants who reported higher levels of body shame would (a) report higher levels of body dissatisfaction, and (b) demonstrate less improvement in response to the Positive Bodies program. A total of 52 women aged 17-54 years completed self-report measures of self-esteem, body area satisfaction, body image quality of life, body shame, and self-surveillance at the commencement and conclusion of the program. The results provided preliminary support for the overall effectiveness of the program. Contrary to predictions, higher body shame was associated with greater improvements in indicators of body image over time. Further comparisons with a control or treatment comparison group are required; however, the results support benefits for individuals with body dissatisfaction, particularly those reporting higher levels of body shame.

    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

  16. Does body size affect a bird's sensitivity to patch size and landscape structure?

    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. ??

    The abundance of gut microbiota can be viewed as a quantitative trait, which is affected by the genetics and environment of the host. To quantify the effects of host genetics, we calculated the heritability of abundance of specific microorganisms and genetic correlations among them in the gut microbiota of two lines of chickens maintained under the same husbandry and dietary regimes. The lines, which originated from a common founder population, had undergone >50 generations of selection for high (HW) or low (LW) 56-day body weight and now differ by more than 10-fold in body weight at selection age. We identified families of Paenibacillaceae, Streptococcaceae, Helicobacteraceae, and Burkholderiaceae that had moderate heritabilities. Although there were no obvious phenotypic correlations among gut microbiota, significant genetic correlations were observed. Moreover, the effects were modified by genetic selection for body weight, which altered the quantitative genetic background of the host. Heritabilities for Bacillaceae, Flavobacteriaceae, Helicobacteraceae, Comamonadaceae, Enterococcaceae, and Streptococcaceae were moderate in LW line and little to zero in the HW line. These results suggest that loci associated with these microbiota families, while exhibiting genetic variation in LW, have been fixed in HW line. Also, long term selection for body weight has altered the genetic correlations among gut microbiota. No microbiota families had significant heritabilities in both the LW and HW lines suggesting that the presence and/or absence of a particular microbiota family either has a strong growth promoting or inhibiting effect, but not both. These results demonstrate that the quantitative genetics of the host have considerable influence on the gut microbiota. PMID:24608294

    Preparing young students to resist the sociocultural pressures that contribute to body image and eating problems in American culture poses a monumental challenge. This project determined if the 11-lesson "Healthy Body Image: Teaching Kids to Eat and Love Their Bodies Too!" curriculum would have a positive effect when presented to upper elementary school children. A controlled study with 415 students measured changes from pretest to posttest related to: 1) body image; 2) knowledge about the biology of size, shape, and restricted hunger or dieting; 3) body size prejudice; 4) media awareness; 5) self-image; and 6) lifestyle behavior. Boys and girls who completed the curriculum showed significant or notable improvement compared to a control group not exposed to the curriculum. Results suggest it is possible to provide children with a knowledge base to use as they face increasing pressures about appearance, weight, and eating in the critical middle school years.

    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.

    Cancer treatment has the potential for limited or permanent impact on body image and self-esteem. Physical changes that impose cosmetic and appearance challenges can be psychologically immobilizing for women with cancer. Their ability to function within social roles may also be affected. This paper describes a restorative strategy as part of a comprehensive cancer rehabilitation program. Women who have had cancer are invited to an informal event that combines fashion modeling with practical suggestions for adaptive and cosmetic needs. Fashion and beauty products are displayed and informational materials provided. It incorporates components of Look Good ... Feel Better, a joint program of the American Cancer Society, the National Cosmetology Association and the Cosmetic, Toiletry, and Fragrance Association Foundation. Evaluations show this program to be helpful and enjoyable for attendees. Health professionals can utilize this strategy in a variety of settings as a component of a cancer rehabilitation program.

    Breast self-examinations (BSE) and skin self-examinations (SSE) represent cost-effective and time-efficient approaches to cancer detection. Given their utility, it is important to determine who is likely to perform these behaviors regularly and why. Because BSE and SSE require close examination of one's body, women who are less satisfied and less comfortable with their bodies may perform these behaviors less often. This study sought to determine if a relationship exists between body image and BSE and SSE behaviors and intentions. Ninety-three women completed measures assessing body image, past performance of and future intentions to perform BSE and SSE. Results indicated that body image was related to past performance of SSE. Having greater body-areas satisfaction and more favorable global evaluations of appearance were related to having performed SSE more frequently in the past year. Future research should further examine this relationship utilizing longitudinal designs and more diverse populations.

    "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.

  4. Identification of radiolucent foreign bodies in tissue using optoacoustic spectroscopic imaging

    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.

    The purpose of this research was to investigate the differences in the effect of hysterectomy on body image, self-esteem, and marital adjustment in Turkish women with gynecologic cancer based on specific independent variables, including age, education, employment, having or not having children, and income. This cross-sectional study compared a group of women who underwent a hysterectomy (n = 100) with a healthy control group (n = 100). The study findings indicate that women who had a hysterectomy were found in worse conditions in terms of body image, self-esteem, and dyadic adjustment compared to healthy women. In terms of dyadic adjustment and body image among women who had undergone a hysterectomy, those with lower levels of income and education were found in poorer conditions. The study's findings show that hysterectomies have negative effects on body image, self-esteem, and dyadic adjustment in women affected by gynecologic cancer. Nursing assessment of self-esteem and marital adjustment indicators and implementation of strategies to increase self-confidence and self-esteem are needed for high-risk 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

    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.

    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

    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.

  13. One size does not fit all: using variables other than the thin ideal to understand Black women's body image.

    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.

  14. EXPLORER: Changing the molecular imaging paradigm with total-body PET/CT (Conference Presentation)

    Cherry, Simon R.; Badawi, Ramsey D.; Jones, Terry

    2016-04-01

    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.

  15. 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.

  16. Muscimol microinjected in the arcuate nucleus affects metabolism, body temperature & ventilation.

    2016-06-15

    Effects of microinjection of 2 doses of γ-aminobutyric acid (GABA)A receptor agonist, muscimol (M), into the hypothalamic arcuate nucleus on oxygen consumption and control of ventilation over time and body temperature (BT) at the end of the experiment were compared in adult male and female rats. Relative to cerebrospinal fluid (CSF, 0 nmol), BT was decreased only in male rats with both doses of M, while in female rats, the 5 nmol dose depressed oxygen consumption. Ventilation was depressed by 5 nmol M in male and 10 nmol M in female rats by decreasing tidal volume. M did not affect the ventilatory response of male or female rats to hypoxia, whereas in females 5 and 10 nmol M and in males 10 nmol M depressed the ventilatory response to hypercapnia. Thus, in rats GABAA receptors in the arcuate nucleus modulate BT, oxygen consumption, and ventilation in air and in response to hypercapnia in a sexually dimorphic manner.

    Weight gain and body fat increase the risk of cardiometabolic disease. Cross-sex hormone therapy in transgender persons leads to changes in body weight and body composition, but it is unclear to what extent. We performed a meta-analysis to investigate the changes in body weight, body fat and lean body mass during cross-sex hormone therapy in transgender persons. We searched the PubMed database for eligible studies until November 2015. Ten studies reporting changes in body weight, body fat or lean mass in hormone naive transgender persons were included, examining 171 male-to-female and 354 female-to-male transgender people. Pooled effect estimates in the male-to-female group were +1.8 kg (95% CI: 0.2;3.4) for body weight, +3.0 kg (2.0;3.9) for body fat and -2.4 kg (-2.8; -2.1) for lean body mass. In the female-to-male group, body weight changed with +1.7 kg (0.7;2.7), body fat with -2.6 kg (-3.9; -1.4) and lean body mass with +3.9 kg (3.2;4.5). Cross-sex hormone therapy increases body weight in both sexes. In the male-to-female group, a gain in body fat and a decline in lean body mass are observed, while the opposite effects are seen in the female-to-male group. Possibly, these changes increase the risk of cardiometabolic disease in the male-to-female group.

  18. Explaining rigid dieting in normal-weight women: the key role of body image inflexibility.

    Restrictive dieting is an increasing behavior presented by women in modern societies, independently of their weight. There are several known factors that motivate diet, namely a sense of dissatisfaction with one's body and unfavorable social comparisons based on physical appearance. However, dieting seems to have a paradoxical effect and has been considered a risk factor for weight gain and obesity in women and for maladaptive eating. Nevertheless, the study of the emotional regulation processes that explain the adoption of inflexible and rigid eating behaviors still remains little explored. In this line, the present study aims to explore why normal-weight women engage in highly rigid and inflexible diets. We hypothesize that body and weight dissatisfaction and unfavorable social comparisons based on physical appearance explain the adoption of inflexible eating rules, through the mechanisms of body image inflexibility. The current study comprised 508 normal-weight female college students. Path analyses were conducted to explore the study's hypotheses. Results revealed that the model explained 43 % of inflexible eating and revealed excellent fit indices. Furthermore, the unwillingness to experience unwanted events related to body image (body image inflexibility) mediated the impact of body dissatisfaction and unfavorable social comparisons on the adoption of inflexible eating rules. This study highlights the relevance of body image inflexibility to explain rigid eating attitudes, and it seems to be an important avenue for the development of interventions focusing on the promotion of adaptive attitudes towards body image and eating in young women.

    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.

    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

    Multiple sclerosis (MS) is a disease that results in widespread damage to the nervous system. One consequence of this disease is the emergence of enhanced tremor. This study was designed to (1) compare the tremor responses of persons with MS to that of healthy adults and to (2) examine the impact of whole body position (i.e., seated/standing) on tremor. Bilateral postural tremor was recorded using accelerometers attached to each index finger. Results revealed some similarity of tremor between groups in regard to the principal features (e.g., presence of peaks in similar frequency ranges). However, significant differences were observed with tremor for the MS persons being of greater amplitude, more regular (lower ApEn) and more strongly coupled across limbs compared to the elderly. The effects of body position were consistent across all subjects, with tremor increasing significantly from sitting-to-standing. However, the tremor increase for the MS group was greater than the elderly. Overall, the tremor for MS group was negatively affected by both this disease process and the nature of the task being performed. This latter result indicates that tremor does not simply reflect the feed-forward output of the neuromotor system but that it is influenced by the task constraints.

  2. 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.

    [Purpose] The purpose of this study was to identify factors related to physical characteristics and lifestyle that affect pulmonary function. [Subjects and Methods] Ninety seven healthy male workers were recruited for this study, and basic information and details about lifestyle were collected. Body composition analyzer and visceral fat measuring device were conducted as measurements. Pulmonary function was measured using spirometer. A multiple stepwise linear regression analysis was performed with pulmonary function as the dependent variable. Variables with a significant association with pulmonary function on univariate analysis were imputed as independent variables. [Results] Height, fat free mass, upper extremity muscle mass, lower extremity muscle mass, and trunk muscle mass had significant positive correlations with FEV1 and FVC. Age, percentage of body fat, and visceral fat area were negatively correlated with FEV1 and FVC. Regarding the association between pulmonary function and lifestyle, a significant difference was found between the smoking index and the presence or absence of metabolic syndrome risk factors and both FEV1 and FVC. The multiple stepwise linear regression analysis with FEV1 as the dependent variable, adjusted for age and height, revealed that visceral fat area and fat free mass were significantly associated with FEV1. A similar analysis, FVC as the dependent variable identified visceral fat area. [Conclusion] FEV1 was independently associated with visceral fat area and fat free mass. FVC was independently associated with visceral fat area. These results may be valuable in preventing the decrease in respiratory function and, hence, in further preventing the onset of COPD.

    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.

    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.

    During adolescence, nutrition needs are high; however the literature shows that few adolescents are following standardized nutritional requirements. A few weeks before an intervention about nutrition to high school adolescents in Lausanne, they were invited to fill in a self-reported questionnaire about their nutrition modes and habits, and their self-image satisfaction (N = 198). Results show that only 5% of youth are eating 5 fruits and vegetables per day and only 29% 3 to 5 dairy products. 21% of female and 6% of boys are not satisfied about their self-image, and those exhibiting a poor self-image tend to adopt health compromising eating patterns in a higher proportion. During adolescence it is important not only to investigate the nutritional habits but also one's self image.

    Optical imaging is emerging as a powerful tool to study physiological, neurological, oncological, cell biological, molecular, developmental, immunological, and infectious processes. This unit describes the use of fluorescent reporters for biological organisms, components, or events. We describe the application of fluorescence imaging to examination of infectious processes, in particular subcutaneous and pulmonary bacterial infections, but the same approaches are applicable to nearly any infectious route. The strategies described use mycobacterial infections as an example, but nearly identical systems can be used for Pseudomonas, Legionella, Salmonella, Escherichia, Borrelia, and Staphylococus, suggesting that the approaches are generally applicable to nearly any infectious agent. Two strategies for fluorescence imaging are described: the first method uses reporter enzyme fluorescence (REF), and the second uses fluorescent proteins for fluorescence imaging. Methods are described in detail to facilitate successful application of these emerging technologies to nearly any experimental system.

    Body part recognition based on CT slice images is very important for many applications in PACS and CAD systems. In this paper, we propose a novel approach that can recognize which body part a slice image belongs to robustly. We focus on how to effectively express and use the unique statistical information of the correlation between the CT value and the position information of each body part. We apply the machine learning method AdaBoost to express and use this statistical information. Our approach consists of a training process and a recognition process. In the training process, we first define the whole body using a set of specific classes to ensure that training images in the same class have a high similarity, and prepare a training image set (positive samples and negative samples) for each class. Second, the training images are normalized to a fixed size and rotation in each class. Third, features are calculated for each normalized training image. Finally, AdaBoosted histogram classifiers are trained. After the training process, each class has its own classifiers. In the recognition process, given a series of CT images, the scores of all classes for each slice image are calculated based on the classifiers obtained in the training process. Then, based on the scores of each slice and a simple model of body part sequence continuity, we use dynamic programming (DP) to eliminate false recognition results. Experimental results on 440 unknown series including lesions show that our approach has high a recognition rate.

    Young women increasingly spend time on social media, but the relationship of this exposure to body image is still in the initial stages of exploration. In this study the authors used social comparison theory to examine the relationship between time spent on Facebook and body image. A survey of 881 U.S. college women was conducted in April-May 2013. Findings showed that 10.1% had posted about weight, body image, exercise, or dieting, and 27.4% had commented on friends' posts or photos. More time on Facebook related to more frequent body and weight comparisons, more attention to the physical appearance of others, and more negative feelings about their bodies for all women. For women who wanted to lose weight, more time on Facebook also related to more disordered eating symptoms.

    2000-12-01

    This study examined how discrepancies between actual and ideal body images are related to eating and exercise patterns. A total of 115 college-age women completed the Body Discrepancy Scale (BDS, a measure of the discrepancy between one's "actual" vs. "ideal" weight and size), a leisure-time physical activity survey, and questionnaires assessing the intake of fat and fiber (i.e., fruits and vegetables), as well as measures of maladaptive eating attitudes and behaviors. Partial correlations (controlling for Body Mass Index, BMI) showed that scores on the BDS were significantly (P's<.05) associated with low levels of physical activity (r=-.28), with low levels of fruit and vegetable consumption (r=-.19), and with high levels of body image dissatisfaction (r=.32) and binge eating (r=.32). Collectively, these findings suggest that discrepancies between actual and ideal body images are associated with maladaptive eating and exercise patterns.

    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.

    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

    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

    This cross-sectional study contributes to the literature on whether body dissatisfaction is a barrier/facilitator to engaging in physical activity and to investigate the impact of mass-media messages via computer-time on body dissatisfaction. High-school students (N = 1501) reported their physical activity, computer-time (homework/leisure) and body dissatisfaction. Researchers measured students' weight and height. Analyses revealed that body dissatisfaction was negatively associated with physical activity on both genders, whereas computer-time was associated only with girls' body dissatisfaction. Specifically, as computer-homework increased, body dissatisfaction decreased; as computer-leisure increased, body dissatisfaction increased. Weight-related interventions should improve body image and physical activity simultaneously, while critical consumption of mass-media interventions should include a computer component.

    Past research on adults' body image has typically used small convenience samples, limiting the ability to examine associations of personal characteristics to body satisfaction. This study of 52,677 heterosexual adults ages 18-65 examined associations of body satisfaction to age, height, gender, and body mass index (BMI). Age and height were mostly unrelated to body satisfaction. Consistent with an Objectification Theory perspective, fewer men than women reported being too heavy (41% versus 61%), rated their body as unattractive (11% versus 21%), or avoided wearing a swimsuit in public (16% versus 31%). Men felt better about their bodies than women across most of the weight span, although among underweight individuals, women felt better than men. Slender women (BMIs 14.5-22.49) were more satisfied than most other women (BMIs 22.5-40.5). Among men, underweight and obese men were least satisfied. These findings highlight gender differences in the association of weight to body satisfaction.

    We examined the impact of surgical treatments (breast-conserving surgery [BCS], mastectomy alone, mastectomy with reconstruction) and surgical side-effects severity on early stage (0-IIA) breast cancer patients' body image over time. We interviewed patients at 4-6 weeks (T1), six (T2), 12 (T3), and 24 months (T4) following definitive surgical treatment. We examined longitudinal relationships among body image problems, surgery type, and surgical side-effects severity using the Generalized Estimating Equation approach, controlling for demographic, clinical, and psychosocial factors. We compared regression coefficients of surgery type from two models, one with and one without surgical side-effects severity. Of 549 patients enrolled (mean age 58; 75% White; 65% BCS, 12% mastectomy, 23% mastectomy with reconstruction), 514 (94%) completed all four interviews. In the model without surgical side-effects severity, patients who underwent mastectomy with reconstruction reported poorer body image than patients who underwent BCS at T1-T3 (each P < 0.02), but not at T4. At T2, patients who underwent mastectomy with reconstruction also reported poorer body image than patients who underwent mastectomy alone (P = 0.0106). Adjusting for surgical side-effects severity, body image scores did not differ significantly between patients with BCS and mastectomy with reconstruction at any interview; however, patients who underwent mastectomy alone had better body image at T2 than patients who underwent mastectomy with reconstruction (P = 0.011). The impact of surgery type on body image within the first year of definitive surgical treatment was explained by surgical side-effects severity. After 2 years, body image problems did not differ significantly by surgery type.

    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.

    2011-01-01

    In humans, there is a trade-off between the need to respond optimally to the salient environmental stimuli and the need to meet our long-term goals. This implies that a system of salience sensitive control exists, which trades task-directed processing off against monitoring and responding to potentially high salience stimuli that are irrelevant to the current task. Much cognitive control research has attempted to understand these mechanisms using non-affective stimuli. However, recent research has emphasized the importance of emotions, which are a major factor in the prioritization of competing stimuli and in directing attention. While relatively mature theories of cognitive control exist for non-affective settings, exactly how emotions modulate cognitive processes is less well understood. The attentional blink (AB) task is a useful experimental paradigm to reveal the dynamics of both cognitive and affective control in humans. Hence, we have developed the glance–look model, which has replicated a broad profile of data on the semantic AB task and characterized how attentional deployment is modulated by emotion. Taking inspiration from Barnard’s Interacting Cognitive Subsystems, the model relies on a distinction between two levels of meaning: implicational and propositional, which are supported by two corresponding mental subsystems: the glance and the look respectively. In our model, these two subsystems reflect the central engine of cognitive control and executive function. In particular, the interaction within the central engine dynamically establishes a task filter for salient stimuli using a neurobiologically inspired learning mechanism. In addition, the somatic contribution of emotional effects is modeled by a body-state subsystem. We argue that stimulus-driven interaction among these three subsystems governs the movement of control between them. The model also predicts attenuation effects and fringe awareness during the AB.

    Compared with microwave, THz has higher resolution, and compared with infrared, THz has better penetrability. Human body radiate THz also, its photon energy is low, it is harmless to human body. So THz has great potential applications in the body searching system. Dual-band images may contain different information for the same scene, so THz dual-band imaging have been a significant research subject of THz technology. Base on the dual-band THz passive imaging system which is composed of a 94GHz and a 250GHz cell detector, this paper researched the preprocessing and fusion algorithm for THz dual-band images. Firstly, THz images have such problems: large noise, low SNR, low contrast, low details. Secondly, the stability problem of the optical mechanical scanning system makes the images less repetitive, obvious stripes and low definition. Aiming at these situations, this paper used the BM3D de-noising algorithm to filter noise and correct the scanning problem. Furthermore, translation, rotation and scaling exist between the two images, after registered by the intensity-base registration algorithm, and enhanced by the adaptive histogram equalization algorithm, the images are fused by image fusion algorithm based on wavelet. This effectively reduced the image noise, scan distortion and matching error, improved the details, enhanced the contrast. It is helpful to improve the detection efficiency of hidden objects too. Method in this paper has a substantial effect for improving the dual-band THz passive imaging system's performance and promoting technology practical.

  5. Online quantitative analysis of multispectral images of human body tissues

    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 uses a mixed-method approach to examine the relationship between body image and sexual health among adolescent boys. In Study 1, eight 12th-grade boys participated in semistructured interviews focusing on dating and sexuality. Qualitative analyses revealed several differences between boys who were satisfied with their bodies and boys who were not. Specifically, boys who were satisfied with their bodies indicated that they were clear about what they wanted sexually and were comfortable communicating those wants with partners. In contrast, boys with low body satisfaction were often unclear about their sexual choices and resisted talking about sexuality with partners. Study 2 examined these same themes using quantitative data from 149 boys from the 12th grade who completed surveys assessing body image, sexual experiences, and sexual attitudes. Body satisfaction was significantly associated with sexual agency and with clarity of personal sexual values. Implications for promoting adolescent sexual health are discussed.

    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).

    Breast cancer and its treatment can significantly affect a woman’s body image. As such, it would be useful to understand the importance or value these patients place on their appearance. We evaluated the factor structure of the Appearance Schemas Inventory- Revised (ASI-R), a measure of body image investment, with a sample of 356 breast cancer patients undergoing mastectomy and breast reconstruction. Using confirmatory and exploratory factor analyses, we found that a 3-factor model demonstrated an improvement in fit over the original 2-factor structure of the ASI-R. These factors were named Appearance Self-Evaluation, Appearance Power/Control, and Appearance Standards and Behavior. The three aforementioned factors demonstrated acceptable internal consistency reliabilities. Our findings have implications for the use of the ASI-R in an oncology setting, specifically for breast cancer patients undergoing reconstruction. PMID:25600137

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

    This study aimed to investigate prospective predictors and health-related outcomes of positive body image in adolescent girls. In so doing, the modified acceptance model of intuitive eating was also examined longitudinally. A sample of 298 girls aged 12 to 16 years completed a questionnaire containing measures of body appreciation, potential predictors, and a range of health outcomes, at 2 time points separated by 1 year. Longitudinal change regression models showed that perceived body acceptance by others (positively), self-objectification and social comparison (negatively), and body appreciation (positively) prospectively predicted intuitive eating 1 year later, consistent with the acceptance model of intuitive eating. Perceived body acceptance by others was the only proposed predictor to prospectively predict an increase in body appreciation over time. Time 1 body appreciation prospectively predicted a decrease in dieting, alcohol, and cigarette use, and an increase in physical activity 1 year later. In particular, girls with low body appreciation were more likely than girls with high body appreciation to take up alcohol and cigarette use between time points. The results highlight body appreciation as an important target for interventions designed to prevent or delay the uptake of alcohol and cigarette consumption among girls. More broadly, they suggest that a positive body image can confer considerable benefit for adolescent girls.

    Body dissatisfaction (BD) is a highly prevalent feature amongst females in society, with the majority of individuals regarding themselves to be overweight compared to their personal ideal, and very few self-describing as underweight. To date, explanations of this dramatic pattern have centred on extrinsic social and media factors, or intrinsic factors connected to individuals' knowledge and belief structures regarding eating and body shape, with little research examining links between BD and basic cognitive mechanisms. This paper reports a correlational study in which visual and executive cognitive processes that could potentially impact on BD were assessed. Visual memory span and self-rated visual imagery were found to be predictive of BD, alongside a measure of inhibition derived from the Stroop task. In contrast, spatial memory and global precedence were not related to BD. Results are interpreted with reference to the influential multi-component model of working memory.

  2. Africa adorned: body image and symbols of physical beauty.

    PubMed

    Davidson, Leah

    2010-01-01

    African concepts of beauty and adornments of the body reflect a celebration of life in the face of death. They are derived from ancient times and the sense of man as a biological animal, within the context of life with other beasts. Among these, man is the only one who is born naked without nature's protections and adornment, such as fur, stripes, or feathers. The body is therefore an asset which must be guarded and covered and yet be expressive of strength as well as sexual desire, so as to attract a mate. Beauty, as a source of self-regard in African cultures is also often achieved through empathic identification with animals. Primordial African attitudes to life and death and symbols of beauty apparently influenced Freud's fourth instinct theory conceptions of Eros and Thanotos, as well as Erich Fromm's ideas about life-loving and death-loving societies, as illustrated in selected quotations from their writings.

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

  4. Ethics and images of suffering bodies in humanitarian medicine.

    PubMed

    Calain, Philippe

    2013-12-01

    Media representations of suffering bodies from medical humanitarian organisations raise ethical questions, which deserve critical attention for at least three reasons. Firstly, there is a normative vacuum at the intersection of medical ethics, humanitarian ethics and the ethics of photojournalism. Secondly, the perpetuation of stereotypes of illness, famine or disasters, and their political derivations are a source of moral criticism, to which humanitarian medicine is not immune. Thirdly, accidental encounters between members of the health professions and members of the press in the humanitarian arena can result in misunderstandings and moral tension. From an ethics perspective the problem can be specified and better understood through two successive stages of reasoning. Firstly, by applying criteria of medical ethics to the concrete example of an advertising poster from a medical humanitarian organisation, I observe that media representations of suffering bodies would generally not meet ethical standards commonly applied in medical practice. Secondly, I try to identify what overriding humanitarian imperatives could outweigh such reservations. The possibility of action and the expression of moral outrage are two relevant humanitarian values which can further be spelt out through a semantic analysis of 'témoignage' (testimony). While the exact balance between the opposing sets of considerations (medical ethics and humanitarian perspectives) is difficult to appraise, awareness of all values at stake is an important initial standpoint for ethical deliberations of media representations of suffering bodies. Future pragmatic approaches to the issue should include: exploring ethical values endorsed by photojournalism, questioning current social norms about the display of suffering, collecting empirical data from past or potential victims of disasters in diverse cultural settings, and developing new canons with more creative or less problematic representations of

METHODS A detailed review was undertaken of the Brazilian literature on body image, selecting published articles, dissertations and theses from the SciELO, SCOPUS, LILACS and PubMed databases and the CAPES thesis database. Google Scholar was also used. There was no start date for the search, which used the following search terms: “body image” AND “Brazil” AND “scale(s)”; “body image” AND “Brazil” AND “questionnaire(s)”; “body image” AND “Brazil” AND “instrument(s)”; “body image” limited to Brazil and “body image”. RESULTS The majority of measures available were intended to be used in college students, with half of them evaluating satisfaction/dissatisfaction with the body. Females and adolescents of both sexes were the most studied population. There has been a significant increase in the number of available instruments. Nevertheless, numerous published studies have used non-validated instruments, with much confusion in the use of the appropriate terms (e.g., perception, dissatisfaction, distortion). CONCLUSIONS Much more is needed to understand body image within the Brazilian population, especially in terms of evaluating different age groups and diversifying the components/dimensions assessed. However, interest in this theme is increasing, and important steps have been taken in a short space of time. PMID:24897056

    [Purpose] The purpose of this study was to identify factors related to physical characteristics and lifestyle that affect pulmonary function. [Subjects and Methods] Ninety seven healthy male workers were recruited for this study, and basic information and details about lifestyle were collected. Body composition analyzer and visceral fat measuring device were conducted as measurements. Pulmonary function was measured using spirometer. A multiple stepwise linear regression analysis was performed with pulmonary function as the dependent variable. Variables with a significant association with pulmonary function on univariate analysis were imputed as independent variables. [Results] Height, fat free mass, upper extremity muscle mass, lower extremity muscle mass, and trunk muscle mass had significant positive correlations with FEV1 and FVC. Age, percentage of body fat, and visceral fat area were negatively correlated with FEV1 and FVC. Regarding the association between pulmonary function and lifestyle, a significant difference was found between the smoking index and the presence or absence of metabolic syndrome risk factors and both FEV1 and FVC. The multiple stepwise linear regression analysis with FEV1 as the dependent variable, adjusted for age and height, revealed that visceral fat area and fat free mass were significantly associated with FEV1. A similar analysis, FVC as the dependent variable identified visceral fat area. [Conclusion] FEV1 was independently associated with visceral fat area and fat free mass. FVC was independently associated with visceral fat area. These results may be valuable in preventing the decrease in respiratory function and, hence, in further preventing the onset of COPD.

    Ethanol occurs in fleshy fruit as a result of sugar fermentation by both microorganisms and the plant itself; its concentration [EtOH] increases as fruit ripens. At low concentrations, ethanol is a nutrient, whereas at high concentrations, it is toxic. We hypothesized that the effects of ethanol on the foraging behavior of frugivorous vertebrates depend on its concentration in food and the body condition of the forager. We predicted that ethanol stimulates food consumption when its concentration is similar to that found in ripe fruit, whereas [EtOH] below or above that of ripe fruit has either no effect, or else deters foragers, respectively. Moreover, we expected that the amount of food ingested on a particular day of feeding influences the toxic effects of ethanol on a forager, and consequently shapes its feeding decisions on the following day. We therefore predicted that for a food-restricted forager, ethanol-rich food is of lower value than ethanol-free food. We used Egyptian fruit bats ( Rousettus aegyptiacus) as a model to test our hypotheses, and found that ethanol did not increase the value of food for the bats. High [EtOH] reduced the value of food for well-fed bats. However, for food-restricted bats, there was no difference between the value of ethanol-rich and ethanol-free food. Thus, microorganisms, via their production of ethanol, may affect the patterns of feeding of seed-dispersing frugivores. However, these patterns could be modified by the body condition of the animals because they might trade-off the costs of intoxication against the value of nutrients acquired.

    Many studies have examined gender issues in children's literature, but a review of the literature reveals that few studies have examined the instances of fatness in the images. Studying the fat representation in the images of children's literature is important because exposure to a variety of body types may slow the rate of children's body…

    This study examined the impact of exposure to fashion magazines on women's body image satisfaction. Participants were 39 undergraduate women, randomly assigned to two experimental conditions: half viewed fashion magazines prior to completing a body image satisfaction survey, and the remaining half, news magazines. Mean height and weight did not differ for the two groups. As hypothesized, women who viewed fashion magazines preferred to weigh less, were less satisfied with their bodies, were more frustrated about their weight, were more preoccupied with the desire to be thin, and were more afraid of getting fat than were their peers who viewed news magazines.

    The human body literally glimmers. The intensity of the light emitted by the body is 1000 times lower than the sensitivity of our naked eyes. Ultraweak photon emission is known as the energy released as light through the changes in energy metabolism. We successfully imaged the diurnal change of this ultraweak photon emission with an improved highly sensitive imaging system using cryogenic charge-coupled device (CCD) camera. We found that the human body directly and rhythmically emits light. The diurnal changes in photon emission might be linked to changes in energy metabolism.

    This study investigated body image issues and the usefulness of self-reported measurements among Hmong American children, 9-18 years using mixed methodology. Twelve focus groups were conducted (n=68) and a silhouette drawing instrument and six questions pertaining to body image were administered (n=335). About 50% of the children were either overweight or obese and 23% were short statured relative to US norms. About 70% of the girls and 53% of the boys selected smaller body ideals than their perceived body sizes. Further, 21% of the girls and 31% of the boys were satisfied with their bodies. Children underestimated their weights and overestimated their heights. During focus groups children reported that parents, peers, and media influenced their body image perceptions. Our results indicate that the majority of Hmong children are dissatisfied with their bodies and tend to endorse American ideals of beauty and attractiveness rather than the heavier, traditional Hmong body ideals supported by their parents.

    First results of endoscopic applications of optical coherence tomography (OCT) in gynecology are presented. We have studied mucosa of uterus, uterine cervix and vagina in vivo. Images of healthy endometrium in different stages of menstrual cycle have been recorded. For uterine cervix not only OCT data of normal state but some kids of pathology have been analyzed. Capability of OCT to identify alterations of mucosa makes this method promising for early diagnosis of tumors and precise guiding of excisional biopsy.

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

    The current study explored the relation between sexual orientation, media persuasion, and eating and body image concerns among 78 college men (39 gay; 39 straight). Participants completed measures of sexual orientation, eating disorder symptoms, appearance-related anxiety, perceived importance of physical attractiveness, perceptions of media influence, and media exposure. Gay men scored significantly higher on drive for thinness, body dissatisfaction, and body image-related anxiety than their straight counterparts. Additionally, perceptions of media influence were higher for gay men, and significantly mediated the relation between sexual orientation and eating and body image concerns. Sexual orientation also moderated the relation between perceived media influence and beliefs regarding the importance of physical attractiveness, as this relation was significant for gay men, but not straight men. The current findings suggest that gay men's increased vulnerability to media influence partially accounts for the relatively high rate of eating pathology observed in this population.

    Males are increasingly subjected to pressures to conform to aesthetic body stereotypes. There is, however, comparatively little published research on the aetiology of male body shape concerns. Two experiments are presented, which investigate the relationship between gender specific body shape concerns and colour-naming performance. Each study comprised a between subject design, in which each subject was tested on a single occasion. A pictorial version of a modified Stroop task was used in both studies. Subjects colour-named gender specific obese and thin body shape images and semantically homogeneous neutral images (birds) presented in a blocked format. The first experiment investigated female subjects (N = 68) and the second investigated males (N = 56). Subjects also completed a self-report measure of eating behaviour. Currently dieting female subjects exhibited significant colour-naming differences between obese and neutral images. A similar pattern of colour-naming performance was found to be related to external eating in the male subjects.

    Both maladaptive schemas (MS) and perfectionism have been associated with eating pathology. However, previous research has not examined these variables simultaneously and has not studied possible mediating relationships between MS and multidimensional perfectionism for body image concerns in eating disorder (ED) patients. Eighty-eight female ED patients completed the Young Schema Questionnaire, the Frost Multidimensional Perfectionism Scale, and the Body Attitude Test. Body image concerns were found to be positively related to Personal Standards (PS) and Evaluative Concerns (EC) perfectionism and all five schema domains. PS Perfectionism was positively associated with Disconnection, Other-directedness, and Overvigilance. EC Perfectionism was positively related to Disconnection, Impaired Autonomy, Other-directedness, and Overvigilance. Moreover, EC perfectionism was found to be a significant mediator in the relationship between the schema domains Impaired Autonomy and Overvigilance and body image concerns. These findings denote the importance to address both core beliefs and perfectionism in ED treatment.

    Exposure to the media's "ideal" physique increases mood and body image disturbance, especially for at-risk women. Because exercise decreases mood and body image disturbance, we examined the ability of acute aerobic exercise to moderate the negative psychological impact of exposure to media pictures of the "ideal" female body. Women reporting high drive for thinness and media internalization viewed pictures of either nonphysique or "ideal" physique pictures after engaging in 30min of either aerobic exercise or quiet rest. Compared to the nonphysique pictures, viewing the physique pictures resulted in increased depression and body dissatisfaction. Acute aerobic exercise, however, did not moderate the negative mood states elicited by the media images. Implications of our results and future directions for research are discussed.

    This study focuses on body image discomfort (BID) of 50 adolescent and young adult (AYA) hematologic cancer survivors (age range 15-23; 52% males). The study results were obtained through data from a self-report questionnaire: the Body Uneasiness Test. Findings differed according to gender: a greater proportion of females were in the Risk category of impaired body image than males (χ(2) = 5.258, p < 0.05). No significant body image differences were found according to the type of diagnosis or to the length of survival. To manage survivors' BIDs and to improve their quality of life, assessing BID in AYA cancer survivors is important for identifying those who might be in need of additional supportive care or a program.

    In breast cancer survivors, own body image may change due to physical and psychological reasons, worsening women's living. The aim of the study was to investigate whether body image may affect the functional and quality of life outcomes after a multidisciplinary and educational rehabilitative intervention in sixty women with primary nonmetastatic breast cancer who have undergone conservative surgery. To assess the quality of life was administered The European Organization for Research and Treatment of Cancer Study Group on Quality of Life core questionnaire, while to investigate the psychological features and self-image were administered the following scales: the Body Image Scale, the Hamilton Rating Scale for Depression, and the State-Trait Anxiety Inventory. To assess the recovery of the function of the shoulder were administered: the Disabilities of the Arm, Shoulder, and Hand Questionnaire and the Constant-Murley Score. Data were collected at the baseline, at the end of the intervention, and at 3-month follow-up. We found a general improvement in the outcomes related to quality of life, and physical and psychological features after treatment (P < 0.001). During follow-up period, a higher further improvement in women without alterations in body image in respect of those with an altered self-perception of their own body was found (P = 0.01). In conclusion, the body image may influence the efficacy of a rehabilitative intervention, especially in the short term of follow-up. PMID:25405222
