    2014-01-01

    Objective: To evaluate the influence of self-esteem on levels of body dissatisfaction among adolescent females. Methods: A group of 397 adolescents aged 12 to 17 years were enrolled in the study. The Body Shape Questionnaire (BSQ) was applied to assess body dissatisfaction. The Rosenberg Self-Esteem Scale was used to assess self-esteem. Weight, height, and skinfold thickness were also measured. These anthropometric data were controlled in the statistical analyses. Results: The multiple regression model indicated influence of "positive self-esteem" (R2=0.16; p=0.001) and "negative self-esteem" (R2=0.23; p=0.001) subscales on the BSQ scores. Univariate analysis of covariance demonstrated differences in BSQ scores (p=0.001) according to groups of self-esteem. Conclusion: It was concluded that self-esteem influenced body dissatisfaction in adolescent girls from Juiz de Fora, MG. PMID:25479855

    Butler-Ajibade, Phoebe; Robinson, Seronda A.

    2014-01-01

    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.

    Blow, Julie; Cooper, Theodore V

    2014-01-01

    This study assessed the impact of demographic, mood, acculturation, weight, and accurate weight feedback on body dissatisfaction and satisfaction. One hundred and sixty Hispanic college students completed measures assessing depressive symptoms, acculturation, affect, and body image. Participants were randomized to receive immediate or delayed weight feedback. Three multiple regression analyses assessed predictors of body dissatisfaction, body weight and fitness happiness, and perceived attractiveness. A hierarchical regression model assessed body dissatisfaction after receiving feedback. Results indicate that greater body dissatisfaction was associated with females, greater depressive symptomatology, and higher weight. Body weight and fitness happiness was associated with males and greater positive affect. Perceived attractiveness was related to smoking, greater positive affect, and greater importance placed on weight. Body dissatisfaction was not impacted by accurate weight feedback. Studies assessing the impact of these predictors in weight loss and/or body acceptance interventions are warranted, particularly in Hispanic college students. PMID:24411740

  6. 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.

  7. The role of perfectionism in body dissatisfaction

    PubMed Central

    2013-01-01

    Background Body dissatisfaction is a robust risk factor for disordered eating and is thought to be especially problematic in the presence of high levels of perfectionism. The aim of the current study was to investigate what types of perfectionism were associated with body dissatisfaction. Participants were 1083 women aged 28 to 40 years, with a mean age of 35 years (SD=2.11). Self-reports on perfectionism (using the Frost Multidimensional Perfectionism Scale), weight, height, desired weight, and current and ideal figural stimuli were analysed for the current study. Two measures of body dissatisfaction were utilised: discrepancy between the current and desired weight, and discrepancy between the current and ideal figural stimuli. Results Linear regressions controlling for current body mass index (BMI)/current silhouette examined the relationship between desired BMI/silhouette and simultaneous entry of the 6 subscales of the perfectionism measure. A lower desired BMI was associated with higher levels of Concern over Mistakes and Organisation, and a smaller ideal silhouette was associated with higher levels of Concern over Mistakes and Doubt about Actions and Organisation. Conclusions These findings confirm the pertinence of different dimensions of perfectionism to body dissatisfaction, and suggest avenues to explore in terms of universal prevention work.

  9. Examining body dissatisfaction in young men within a biopsychosocial framework.

    PubMed

    Bardone-Cone, Anna M; Cass, Kamila M; Ford, Jennifer A

    2008-06-01

    This study examined biopsychosocial factors related to body dissatisfaction in young men within multivariate and moderator contexts. A female sample was included as a gender comparison. Male (n=111) and female (n=236) undergraduates filled out self-report questionnaires assessing body mass index (BMI), media influence, a history of weight-related teasing, and socially prescribed perfectionism, along with various indices of body dissatisfaction. Perceived pressure from the media was consistently related to body dissatisfaction in men whereas multiple biopsychosocial variables accounted for body dissatisfaction in women. Socially prescribed perfectionism and a history of weight teasing each moderated the relationship between BMI and male body dissatisfaction, identifying men low in body dissatisfaction. Findings indicate that applying a biopsychosocial framework to the study of body dissatisfaction in men is useful and suggest the need for including other factors, such as male peers and sports involvement, in understanding contributors to male body image. PMID:18463012

    2011-06-01

    This research examined the effects of naturally occurring appearance comparisons on women's affect, body satisfaction, and compensatory cognitions and behaviors. Using ecological momentary assessment, women with high body dissatisfaction and eating pathology (EPHB), high body dissatisfaction (HB), or low body dissatisfaction (LB) recorded their reactions to appearance-focused social comparisons. EPHB and HB women made more upward appearance comparisons than LB women. All women experienced negative emotions and cognitions after upward comparisons, including increased guilt, body dissatisfaction, and thoughts of dieting. EPHB women were most negatively affected by comparisons; they experienced more intense negative emotions, more thoughts of dieting/exercising, and an increase in eating-disordered behavior after upward comparisons. HB women experienced more negative affective consequences and thoughts of dieting than LB women. Results are consistent with social comparison theory and provide important information that may be used to inform eating disorder treatment and prevention efforts. PMID:21496506

    2016-06-01

    For many years, body dissatisfaction and mental health were thought of as Western phenomena and were studied mostly in Caucasian women. Recent studies, however, suggest that these issues are also present in men and in other ethnic groups. This study examined the association between body dissatisfaction and mental health outcomes, with personality traits and neuroticism playing possible predictive roles, using a Korean sample. A total of 545 college students, from five private universities in South Korea, completed assessment measures for depression, self-esteem, neuroticism, and body esteem scales. After controlling for covariates including body mass index and exercise time, body dissatisfaction was seen to play a mediating role between neuroticism and mental health outcomes. Differences between the sexes were also found in this relationship. For men, body dissatisfaction acted as a mediator between neuroticism and depression. For women, body dissatisfaction acted as a mediator between neuroticism and both depression and self-esteem. PMID:27173851

    PubMed

    Bearman, Sarah Kate; Martinez, Erin; Stice, Eric; Presnell, Katherine

    2006-04-01

    The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders parental support deficits, negative affectivity, and self-reported dietary restraint, but not Ideal body internalization, body mass index, and eating pathology, showed significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects. PMID:16912810

    2014-09-01

    Currently, research on interpretation bias and body dissatisfaction is limited. The few experimental paradigms that have been used to explore this phenomenon utilized a method that may not accurately capture the nature of interpretation bias as explained by cognitive theory. The present study investigated the reliability and validity of a novel computerized assessment of interpretation bias (WSAP) for body dissatisfaction, which may more accurately reflect the cognitive processing involved in such bias by implementing the Word Sentence Association Paradigm (WSAP), a previously established method of measuring interpretation bias in other clinical populations. Undergraduate females (n=214) completed the WSAP and other measures. Results indicate initial support for the WSAP as a valid, reliable measure of interpretation bias for body dissatisfaction. Although preliminary, this study contributes to the minimal research in this area and serves as the first psychometric investigation of the WSAP to measure such interpretation bias for body dissatisfaction.

    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.

    2014-11-01

    This study investigated how dissatisfaction with particular aspects of the body was associated with overall body dissatisfaction among male adolescents in Western and Asian cultures. One hundred and six Malaysian Malays, 55 Malaysian Chinese, 195 Chinese from China, and 45 non-Asian Australians aged 12 to 19 years completed a questionnaire assessing dissatisfaction with their overall body and dissatisfaction with varying aspects of their body. Dissatisfaction with the face, height, and hair was positively correlated with overall body dissatisfaction among Malaysian Malays after body mass index, age and dissatisfaction with body areas typically included in measures (weight/shape, upper, middle, and lower body, and muscles) had been controlled for. Dissatisfaction with the face was positively correlated with overall body dissatisfaction among Malaysian Chinese. These findings demonstrate the differences in body focus for males from different cultures and the importance of using assessment measures that address all possible areas of body focus.

    2016-03-01

    Globally there is increasing advocacy for the implementation of laws requiring disclaimer labels to be attached to media images that have been digitally altered, with the goal of reducing the known negative effects of exposure to unrealistic thin ideal imagery for women. The current study used eye tracking technology to establish how digital alteration disclaimer labels affect women's visual attention to fashion magazine advertisements, and the interrelationship with body dissatisfaction and state appearance comparison. Participants were 120 female undergraduate students who viewed four thin ideal advertisements with either no disclaimer, a generic disclaimer, or a more detailed specific disclaimer. It was found that women did attend to the disclaimers. Specifically worded disclaimers directed visual attention towards target body areas, which resulted in increased body dissatisfaction, while state appearance comparison predicted increased body dissatisfaction. Further research is imperative to provide guidance on the most effective use of disclaimer labels. PMID:26498728

    This study aimed to assess the extent, patterns, and predictors of feelings of body dissatisfaction experienced by female German adolescents. Using 3D-avatar software, a sample population of 144 girls between 14 and 17 years of age was asked to estimate their actual body image, their desired body image (individual ideal), and the body image they believed their parents and their best female friend considered to be the ideal body image for them. The participants estimated their actual body mass index (BMI) to be 18.82 ± 3.01. The individual ideal body shape reported was significantly thinner, with a BMI score of 16.84 ± 2.51. Given a girl who stands 1.65 m and weighs 55 kg, this corresponds to a difference in weight of about 5.5 kg. After adjustment for the participant's self-reported BMI, participating in an esthetic sport was correlated with a significantly lower body dissatisfaction. Conversely, low socio-economic status and the amount of time spent watching TV was correlated with a significantly higher body dissatisfaction. Negative body image-related comments made by parents were significantly associated with body dissatisfaction. The girls who participated in this study would like to be an average of 1.97 BMI units thinner. The findings presented here suggest that future intervention measures should focus on the risk groups of physically inactive girls, those who smoke, and those with a lower social status and high rates of TV consumption. Intervention measures would be especially effective in German schools which offer lower education levels and should include the pupils' parents, who should be informed about the negative effects weight- and diet-related comments have on their children's body images.

    2015-09-01

    This study aimed to examine the protective role of positive body image against negative effects produced by viewing thin-idealised media. University women (N=68) completed trait measures of body appreciation and media protective strategies. At a subsequent session, participants viewed 11 thin-ideal advertisements. Body dissatisfaction was assessed before and after advertisement exposure, and state measures of self-objectification, appearance comparison, and media protective strategies were completed. Results indicated that body appreciation predicted less change in body dissatisfaction following exposure, such that participants with low body appreciation experienced increased body dissatisfaction, while those with high body appreciation did not. Although state appearance comparison predicted increased body dissatisfaction, neither state self-objectification nor appearance comparison accounted for body appreciation's protective effect. Trait and state media protective strategies positively correlated with body appreciation, but also did not account for body appreciation's protective effect. The results point to intervention targets and highlight future research directions. PMID:26311661

    2016-09-01

    This systematic review examines body dissatisfaction and the influence of sociocultural messages related to body image among preschool children. The review was conducted according to the PRISMA guidelines and 16 studies were included in the final analysis. Findings suggest that children under the age of 6 years old experience body dissatisfaction, however, the proportion of children who are dissatisfied varied from around 20% to 70%, depending on the method of assessment. The literature was divided on whether preschool aged girls experience more body dissatisfaction than boys. Parental influence appears to be an important factor in the development of preschool children's body dissatisfaction and attitudes. However, more research is needed to understand the influences of children's peers and the media. The need for more sensitive measures of body dissatisfaction and prevention programs for preschool children is discussed. PMID:27352102

    Fat women who endorsed fat acceptance (N=128) were recruited from Radiance Magazine. Relationships between objectified body consciousness (OBC), body esteem, and psychological well-being for the mostly European American sample were similar to those found in other samples. OBC was independently related to body esteem when weight dissatisfaction was controlled. Those who endorsed the need for social change in attitudes towards fat people had higher body esteem and self-acceptance, and lower body shame, than those who endorsed personal acceptance of body size only.

    Extensive research indicates that exposure to media as well as pressure and modeling by sociocultural agents, such as peers and family, are predictive of the development of body image dissatisfaction (BID). This influence is mediated by social comparison and internalization of the thin-ideal. In the current study we assessed comparisons between participants and other women with whom they were in close relationships, (e.g. mother, sister and close female friend), and hypothesized that these would influence women's BID and drive-to-thinness. 283 women between the ages of 18-42 (mean=25.04; SD=3.53) sampled through social networking completed an online self-report which included the original Figure Rating Scale, which yielded self-ideal disparity, as well as a modified version comparing self to mother, self to sister closest-in-age, and self to best friend and then were asked to directly compare themselves to these women. In addition they completed the EDI-2's drive-for-thinness and body dissatisfaction subscales, and reported on Body Mass Index (BMI). Results indicate that comparisons to mothers, sisters, and best friend, were all associated with self-ideal disparity. BMI only slightly mediated this effect. Comparison to sister and to best friend, but not to mother, influenced drive-for-thinness and body dissatisfaction. Positive correlations were found between direct and indirect comparisons to others. Comparison to best friend was the most influential on body ideal. We conclude that comparison to others in close proximity greatly influences women's body ideal and may have a formative role in the development of women's body dissatisfaction. While women cannot choose their mother and sister closest in age, they do choose their best friend; and it is interesting that the comparison to the best friend is so influential. PMID:25064289

    2012-01-01

    With the growing pervasiveness of mass media, individuals of all ages and both sexes are bombarded with images that glorify youthfulness, messages that tie self-worth to thinness, and products that promise youth and beauty forever. Aging women are vulnerable to these societal messages and experience strong pressures to maintain their youth and thinness. As the physiological changes that accompany normal aging move these women farther from the "ideal" image, body dissatisfaction may increase. These women are confronted with the impossible task of trying to defy the natural process of aging through a variety of means, including fashion, cosmetics, selective surgeries, and personal food choices. The resulting body image issues, weight preoccupation, and eating disturbances can lead to voluntary food restriction, depression, social withdrawal, lower self-esteem, and disordered eating, all of which can have a negative impact on quality of life and nutritional status. In this review we explore existing research on body dissatisfaction among middle-aged (30 to 60) and older (over 60) women, discuss the prevalence of body dissatisfaction, its predisposing risk factors, and the resulting eating and body maintenance behaviours, and examine implications for dietetic practice.

    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. PMID:24008185

    In this article, we examine the bodily experiences of Mexican women, to investigate their acceptance of the thin ideal and resulting body dissatisfaction. We conducted semi-structured individual interviews with 30 adult participants in Mexico City. Interviewees accepted the thin body ideal, but experiencing their bodies as signifiers of motherhood protected them from body dissatisfaction. Instead of a personal body project, they engaged in a project of caring for their children's bodies. We suggest that health campaigns directed to adult women should consider the relational aspects of their lives. PMID:23682056

    2007-09-01

    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. PMID:18089272

    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. PMID:18424245

    In a 7-year study, adolescents' body dissatisfaction (N=1370) was examined across four high school years as a function of pubertal development (perceived timing relative to peers and self-reported physical changes measured during Grades 6-10) in the context of the high school transition. Boys and girls who, during early high school, perceived themselves to be late relative to peers were at risk for body dissatisfaction across the high school years. Boys who were late in pubertal development reported more body dissatisfaction in early high school than on-time boys, but then decreased over time. African-American girls reported less body dissatisfaction across the high school years relative to other girls. Asian girls reported more dissatisfaction in early high school than African-American, Latina, and Multiethnic girls, and increased over time. Results highlight the importance of considering late development within context as a risk factor in body dissatisfaction research. PMID:24331829

    2001-01-01

    This study examined the perceived role of three types of sociocultural agents (peers, parents, and media) in influencing body dissatisfaction and dietary restraint in adolescent girls. Participants were 577 grade 10 girls from six schools who completed questionnaires in class and had height and weight measured. Two path analyses resulted in a similar pattern. While current body size strongly predicted ideal body size and body dissatisfaction, perceived influence of multiple sociocultural agents regarding thinness also had a direct relationship with body ideal and dissatisfaction. Dietary restraint was predicted directly from body dissatisfaction and sociocultural influences. Peers, parents, and media varied in their perceived influence. The findings support the idea that those girls who show the most body dissatisfaction and dietary restraint live in a subculture supporting a thin ideal and encouraging dieting. PMID:11572305

    Body dissatisfaction is common among sexual minority (i.e., gay and bisexual) men; however, few studies have investigated the relationship between body dissatisfaction and psychosexual health variables among this population. The data that do exist are exclusively cross-sectional, casting uncertainty regarding temporal associations. Thus, the aims of the current study were to assess the prospective relationship between body dissatisfaction and psychological and sexual health outcomes. Participants were 131 gay and bisexual men who completed a battery of self-report measures across two time points (baseline and 3-month follow-up), including assessment of body dissatisfaction, depressive symptoms, and sexual health variables (sexual self-efficacy and sexual anxiety). Generalized linear modeling was employed to assess the prospective relationship between body dissatisfaction and outcomes variables, accounting for non-normal distributions. Body dissatisfaction significantly predicted elevated depressive symptoms (B = .21, p = .01), lower sexual self-efficacy (B = -.22, p = .04), and elevated sexual anxiety (B = .05, p = .03). Elevated body dissatisfaction is prospectively associated with negative psychological and sexual health outcomes. Given the high prevalence of body image concerns in sexual minority men, depression and/or HIV/STI prevention programs may benefit from routinely assessing for body dissatisfaction among this population, and addressing those who report concerns.

  7. 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. PMID:12629318

    Body image dissatisfaction is a significant risk factor in the onset of eating pathology and depression. Therefore, understanding predictors of negative body image is an important focus of investigation. This research sought to examine the contributions of body mass, appearance conversations with friends, peer appearance criticism and internalization of appearance ideals to body dissatisfaction among adolescents. The sample was comprised of 239 (54% female) adolescents, with a mean age of 16 years. Self-report questionnaires were completed on body dissatisfaction, peer appearance conversations and criticism, internalization of appearance ideals, height and weight. For girls and boys, body mass, appearance conversations with friends, peer appearance criticism and internalized appearance ideals emerged as significant predictors of body dissatisfaction. Gender moderated the effect of body mass on body dissatisfaction. Internalization mediated the relationship between peer appearance conversations and criticism, and body dissatisfaction. These findings suggest that while body mass exerts a differential risk for body dissatisfaction among boys and girls, internalisation may represent a key psychological process that underpins body dissatisfaction among both boys and girls.

    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.

    Emerging research suggests that ethnic identity and American identity are associated with mental health in ethnic minorities and European Americans, respectively. Furthermore, although ethnic identity is associated with diminished body dissatisfaction in minority women, the relationship between American identity and body dissatisfaction is unexplored in all ethnic groups. Accordingly, this study examined the relationships among ethnic identity, American identity, thin-ideal internalization, pressures for thinness, and body dissatisfaction in 1018 ethnically diverse college women. Ethnic identity negatively predicted body dissatisfaction for African Americans, and attenuated the relationship between pressures for thinness and body dissatisfaction for African Americans and Asian Americans, but not European Americans or Latina Americans. Results for American identity were inconclusive. Findings suggest that ethnic identity may be a protective factor against eating pathology for Asian American and African American women.

    Music videos are a particularly influential, new form of mass media for adolescents, which include the depiction of scantily clad female models whose bodies epitomise the ultra-thin sociocultural ideal for young women. The present study is the first exposure experiment that examines the impact of thin models in music videos on the body dissatisfaction of 16-19-year-old adolescent girls (n=87). First, participants completed measures of positive and negative affect, body image, and self-esteem. Under the guise of a memory experiment, they then either watched three music videos, listened to three songs (from the videos), or learned a list of words. Affect and body image were assessed afterwards. In contrast to the music listening and word-learning conditions, girls who watched the music videos reported significantly elevated scores on an adaptation of the Body Image States Scale after exposure, indicating increased body dissatisfaction. Self-esteem was not found to be a significant moderator of this relationship. Implications and future research are discussed. PMID:18089259

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

    High levels of body dissatisfaction have already been reported in the trans population; however, the root of this dissatisfaction, and its association with eating disordered behaviours, has not been studied in-depth. This study aims to assess eating disorder risk by comparing 200 trans people, 200 people with eating disorders and 200 control participants' scores on three subscales of the Eating Disorders Inventory-2 (EDI-2) and to further explore dissatisfaction in the trans participants using the Hamburg Body Drawing Scale (HBDS). The results showed that overall participants with eating disorders scored higher than trans or control groups on all EDI-2 measures, but that trans individuals had greater body dissatisfaction than control participants and, importantly, trans males had comparable body dissatisfaction scores to eating disordered males. Drive for thinness was greater in females (cis and trans) compared with males. In relation to HBDS body dissatisfaction, both trans males and trans females reported greatest dissatisfaction not only for gender-identifying body parts but also for body shape and weight. Overall, trans males may be at particular risk for eating disordered psychopathology and other body image-related behaviours. PMID:25944170

    Body dissatisfaction is recognized as a robust risk factor for eating disorders. Despite over 80% of college men being body dissatisfied, not all men report several levels of eating disorder symptoms. In this study, we examined poor impulse control, social anxiety and internalization of media ideals as potential moderators. Data collected from 405 college-aged men were analysed, using latent variable structural equation modelling approach. All variables investigated have been found to moderate the body dissatisfaction-eating disorder symptomatology, such that male body dissatisfaction was strongly related to men's eating disorder symptomatology when each moderator was at its highest level. Practical implications are discussed. PMID:23988683

    The purpose of this research was to develop, and establish the initial psychometric properties of, the Male Body Dissatisfaction Scale (MBDS). Ninety-five male students were recruited over three phases. An item-remainder analysis was performed in phase I, convergent and discriminant validity assessed in phase II, and test-retest reliability and factor structure assessed in phase III. The MBDS achieved an alpha level of 0.93 and was inversely related to body esteem (p=0.02) and self-esteem (p=0.03), and positively related to how much participants' opinion of themselves was based on their body shape and weight (p<0.01). The MBDS was not related to measures of affect, and was able to distinguish between males endorsing, and not endorsing, elevated body shape and weight concerns (p<0.05). Finally, the MBDS displayed a test-retest reliability coefficient of 0.96 (p<0.01). Findings suggest that the MBDS may fill the need for a reliable and valid measure of body dissatisfaction that allows men to weight particular aspects of their body image according to personal importance.

    2009-06-01

    This study examined a sociocultural model of the influence of parental comments on body shape and eating concerns among males and females. Questionnaires were completed by 338 undergraduates. Participants reported levels of perceived parental comments, internalization of media ideals, appearance comparison, body dissatisfaction, drive for thinness and bulimia. Results revealed that, regardless of gender, internalization and appearance comparison only partially mediated the relationship between parental comments and the outcome variables. The final model for females explained a larger proportion of the variability in body shape and eating concerns than in males, with positive and negative parental comments directly related to body dissatisfaction and through it to eating outcomes. In males, only negative comments were directly related to body dissatisfaction. These findings highlight the role of parental influences in sociocultural models of the development of body dissatisfaction and eating concerns, and the gender-specific patterns of sociocultural influence.

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

    2013-01-01

    Attentional bias toward idealized bodies (men: muscular; women: thin) may cause upward comparisons and increase body dissatisfaction (BD). We investigated attentional biases of 39 men and 41 women with high and low BD toward muscular male bodies and thin female bodies. An eye-tracker measured gaze durations and fixation frequencies while exposing participants to images of thin, normal, muscular, and fat bodies of the same gender. Results revealed longer and more frequent attention toward muscular bodies in high BD men, and toward thin bodies in high BD women. High BD men and women also rated muscular and thin bodies as more attractive than those with low BD. Although men attended to muscular and women attended to thin bodies, both showed an attentional bias toward body types they rated as more attractive. These findings could provide indirect evidence in explaining the relationship between BD and the social comparison theory with attentional bias. PMID:23122552

    Hardit, Saroj K; Hannum, James W

    2012-09-01

    The tripartite model of influence proposes that three primary core sources of influence-parents, peers and media-contribute to the development of body dissatisfaction and disordered eating. In the current study, this model was examined in a sample of 205 undergraduate women. This study added to previous research by investigating mother and father criticism separately and by examining the potential moderating effects of parental attachment in the pathway to body dissatisfaction. Results indicated partial support for the tripartite model of influence. Sociocultural influences (media) were found to be a significant predictor of body dissatisfaction, but not parental or peer criticism. Anxious attachment was found to be a significant moderator on the effects of sociocultural attitudes in body dissatisfaction. Limitations and future research implications are discussed.

    2014-01-01

    This study aimed to investigate the effect of 'retouch free' labels on thin ideal fashion images on women's body dissatisfaction. This represents an experimental analogue to current practice by some fashion magazines. Participants were 224 female undergraduates who viewed a set of fashion shoots with either no label, or a label indicating that the image had not been digitally altered. Results indicated that, although body dissatisfaction increased after exposure to the thin ideal images, there was no significant effect of label type on mood or body dissatisfaction. It was concluded that labelling images as digitally unaltered appears neither helpful nor harmful in terms of body dissatisfaction. Nevertheless, more extensive research is required to guide the most effective use of labels. PMID:24094477

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

    Although once thought primarily to affect White women, body dissatisfaction and disordered eating exist among all racial groups. In the current study, the authors determined whether the relationship between participants' perceived maternal/peer attitudes toward appearance and the outcomes of body dissatisfaction and eating pathology varied by race. Self-reported data, including measures of body dissatisfaction, disordered eating behaviors, body mass index (BMI), and perceptions of maternal/peer attitudes, were collected from December 2012 to May 2013 at a large Mid-Atlantic university. BMI (β = 0.20, p = .01), perceptions of peers' attitudes toward appearance (β = 0.23, p = .02), and White race (β = 0.33, p < .001) were independently associated with body dissatisfaction. Additionally, race interacted with perceptions of peers' attitudes toward appearance such that at high perceptions, African American women reported high levels of body dissatisfaction (β = -0.20, p = .04), but this was not true for White women. Higher perceived peer concern about weight and shape (β = 0.32, p < .001), increased BMI (β = 0.30, p < .001), and White race (β = 0.21, p = .002), also were associated with disordered eating. The results of this study have implications for prevention programs that address disordered eating for racially diverse groups of women. PMID:26583765

    2008-06-01

    With interest in body image and body change behaviors growing around the world, there has been surprisingly little research conducted in Latin America on these issues. In order to gain some understanding of them in this context, this study investigated body image and body change behaviors, and the sociocultural factors that may influence them, among 337 Chilean adolescents aged 12-18 years. Participants completed a questionnaire that assessed BMI, body dissatisfaction, strategies to lose weight and strategies to increase muscle bulk. In addition, perceived pressure from family, peers, and the media to change body shape was evaluated. Results were partially consistent with those reported in Western nations. Girls were found to report greater body dissatisfaction than boys, but no difference was found between males and females in perceived pressure from adults in the family or from older siblings/cousins to lose weight. However, girls experienced higher levels of perceived pressure to lose weight from the media than boys, and boys reported greater perceived pressure from peers to lose weight than girls, and more pressure than girls from all sources to increase muscle bulk. These findings are discussed in relation to research conducted in other contexts, and it is concluded that findings from other locations may not be applied universally. PMID:18463011

    Background/Objectives: To identify the prevalence and factors associated with body dissatisfaction. Subjects/Methods: Birth cohort study investigating 4100 subjects (2187 men and 1913 women) aged between 22 and 23 years who answered questionnaires, including the body satisfaction Stunkard Scale were included in the study; they were weighed and measured. Multinomial logistic regression was used in the crude and adjusted analyses. Results: The prevalence of body dissatisfaction was 64% (95% CI, 62.7–65.6); 42% (95% CI, 40.6–43.6) of the subjects reported feeling larger than the desired body size, and 22% (95% CI, 20.7–23.3) reported feeling smaller than desired. Underweight subjects, subjects with less schooling, poor and sedentary male subjects with low psychological well-being and female subjects who were already mothers were more likely to express body dissatisfaction, perceiving their body as smaller than the desirable body size. The prevalence of body dissatisfaction was also high among overweight subjects, subjects with a high socioeconomic status and married female subjects, who perceived their body size as too large. Minor psychiatric disorders were associated with body dissatisfaction in all subjects, regardless of perceiving themselves as larger or smaller than the desired body size. Most women perceived themselves as larger, but similar proportions of men perceived themselves as too small or too large. Conclusions: Body dissatisfaction was observed among men and women with normal weight, but it was more evident in the obese individuals. Regardless of the nutritional status, both men and women should be appropriately counseled because body size perception can lead to unhealthy behaviors in relation to diet and physical activity.

    The objective of the present study was to identify factors influencing body image dissatisfaction in female patients with anorexia and bulimia nervosa. 61 women, aged 16 to 31, (M = 21.69; SD = 3.85) filled questionnaires evaluating dissatisfaction with their body (Body Dissatisfaction Scale by Garner & al., 1984), attitudes about the body (Body Attitude Test by Probst & al., 1995), avoidance with regard to body image (Body Image Avoidance Questionnaire by Rosen & al., 1991), negative mood states (Hospital Anxiety and Depression Scale by Zigmond and Snaith, 1983) as well as self-esteem (Self-Esteem Inventory by Coopersmith, 1984). Negative appreciation of body size, symptoms of depression, grooming and weighting, lack of familiarity with one's own body, as well as low self-esteem in general, could predict the body image dissatisfaction among eating disordered women. The fact of knowing the most important determinants of body image could give indications for the prevention of the cognitive distortions concerning body image. PMID:20653188

    Clarifying the trajectories of body image and eating concerns in adolescents is critical. We examined longitudinal patterns of development of body dissatisfaction and dietary restriction among early adolescent girls within a sociocultural framework. A sample of 259 school girls (M age = 12.76 years, SD = 0.44) reported on sociocultural influences, body dissatisfaction and dietary restriction at baseline, 8, and 14 months. A subsample provided height and weight. Analyses identified four trajectories of body dissatisfaction: low, moderate-increasing, moderate-decreasing, and high. Three trajectories of dietary restriction emerged: low, moderate, and high. Baseline and 8-month sociocultural variables and BMI differed between the trajectories. A subgroup of girls displays high levels of body image and eating concerns by early adolescence. Sociocultural variables influence these trajectories. PMID:26386562

    Objective One publication reported that lower body satisfaction and lower education were independent predictors of depression in polycystic ovary syndrome (PCOS) women. This study replicates that analysis using different instruments, and adds androgen levels to the model. Methods Cross-sectional analysis of questionnaires (Quick Inventory of Depressive Symptomatology-Self-Report, Body Esteem Scale) and serum androgens from a community cohort with (n=94) and without (n=96) PCOS, matched by BMI category. Non-parametric tests, Spearman correlations, and negative binomial regression models were analyzed. Results Depression symptoms were common (40–60% in lean, overweight and obese BMI categories) in the PCOS cohort, albeit generally of mild severity. The PCOS women had similar depression symptom severity (P > 0.20) and similar body dissatisfaction (P ≥ 0.25) as the regularly cycling women in total and stratified by BMI category. In both the PCOS and non-PCOS cohorts, depression symptom severity was positively correlated with dissatisfaction with physical appearance and physical conditioning (P < 0.02). Body dissatisfaction (especially perception of physical conditioning) was strongly associated with more severe depression symptoms in non-obese PCOS women (BMI<30, P < 0.04) before and after controlling for age, testosterone and free testosterone. In contrast, for obese women with PCOS, depression was unrelated to body dissatisfaction after controlling for age. Conclusions Among non-obese PCOS women, their subjective body image was strongly associated with the severity of their depression symptoms. Most of the obese PCOS cohort had low body satisfaction and depression symptoms, therefore individual differences in the body dissatisfaction scores were not helpful in identifying depression symptom severity. Neither testosterone nor free testosterone were associated with depression symptom severity in PCOS women after controlling for body dissatisfaction and age. US

  10. Does Internalizing Society and Media Messages Cause Body Dissatisfaction, in Turn Causing Disordered Eating?

    The purpose of this study was to examine the predictive influence that internalization of society and media messages has on body dissatisfaction, as well as the prediction influence that body dissatisfaction has on disordered eating behaviors, such as preoccupation with weight, dieting, and eating restraint. A total of 324 participants completed the demographic questionnaire, the Multidimensional Body Self Relations Questionnaire (Cash, 2001 ), the Sociocultural Attitudes Towards Appearance Questionnaire (Heinberg, Thompson, & Stormer, 1995 ) for women, and the Sociocultural Attitudes Towards Appearance Questionnaire-Revised-Male-Version (Cusumano & Thompson, 1997 ) for men, and the locus of control (Rotter, 1966 ). The results of this study found that high internalization leads to body dissatisfaction, in turn, leading to disordered eating behaviors, such as preoccupation with weight, dieting, and eating restraint. This study proposes the implementation of media literacy and education programs that teach college women and men, girls and boys, to think more critically about the media. PMID:26086885

    Sociocultural theory of body dissatisfaction posits that internalization of the media ideal and appearance comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, no data exist regarding the longitudinal relationships between these variables. The aim of this study was to explore longitudinal relationships among internalization of the media-ideal, social appearance comparison, and body dissatisfaction. A sample of 277 Grade 7 school girls (M age = 12.77 years, SD = 0.44) completed measures of internalization of the media ideal, social appearance comparison, and body dissatisfaction at baseline, 8 months, and 14 months. Path analyses indicated that baseline internalization of the media ideal predicted social appearance comparison and body dissatisfaction at 8 months, and social appearance comparison at 8 months predicted body dissatisfaction at 14 months. A reciprocal effect emerged with body dissatisfaction at 8 months predicting internalization of the media ideal at 14 months. The findings inform sociocultural theory of body dissatisfaction, suggesting that internalization of the media ideal precedes and predicts appearance comparison and that body image interventions that target internalization of the media ideal, and social appearance comparison as well as body dissatisfaction are likely to be effective.

  12. Body region dissatisfaction predicts attention to body regions on other women.

    The proliferation of "idealized" (i.e., very thin and attractive) women in the media has contributed to increasing rates of body dissatisfaction among women. However, it remains relatively unknown how women attend to these images: does dissatisfaction predict greater or lesser attention to these body regions on others? Fifty healthy women (mean age=21.8 years) viewed images of idealized and plus-size models; an eye-tracker recorded visual attention. Participants also completed measures of satisfaction for specific body regions, which were then used as predictors of visual attention to these regions on models. Consistent with an avoidance-type process, lower levels of satisfaction with the two regions of greatest reported concern (mid, lower torso) predicted less attention to these regions; greater satisfaction predicted more attention to these regions. While this visual attention bias may aid in preserving self-esteem when viewing idealized others, it may preclude the opportunity for comparisons that could improve self-esteem. PMID:25047004

    Young men who have sex with men (YMSM) may be at greater risk for body dissatisfaction, compared to their heterosexual peers. However, differences within YMSM populations are understudied, precluding the identification of YMSM who are at greatest risk. This study examined body dissatisfaction in a racially/ethnically diverse sample of YMSM ages 18–19 in New York City. Using cross-sectional data from the baseline visit of a longitudinal cohort study of YMSM (N = 591), body dissatisfaction was assessed using the Male Body Attitudes Scale. Three outcomes were modeled using linear regression: (1) overall body dissatisfaction, (2) muscularity dissatisfaction, and (3) body fat dissatisfaction. Covariates in the models included race/ethnicity, sexual orientation, BMI, gay community affiliation, and internalized homonegativity. White YMSM experienced greater body dissatisfaction across the three models. Internalized homonegativity was a statistically significant predictor of dissatisfaction across the three models, though its association with body dissatisfaction was relatively small. The findings point to future avenues of research, particularly qualitative research to explore demographic and cultural nuances in body attitudes among YMSM. PMID:26370403

    We examined the interrelationships of waist-to-hip ratio (WHR), body dissatisfaction, gender, and depressed and eating disordered symptoms cross-sectionally among 131 male and female undergraduates. Based on past findings on physical and mental health, attractiveness, and depressive realism, we predicted that the WHR x Depression x Gender interaction would be significantly related to body dissatisfaction, such that the correspondence between WHR and body dissatisfaction would be more pronounced among depressed than among nondepressed women and men. This hypothesis received support. Implications of our results for work on body dissatisfaction were discussed. PMID:7987354

    2010-01-01

    The present study examined the effects of insecure attachment on the development of negative body image as a contributing factor to the development of disturbed eating patterns in male and female university students. Participants were nonclinical male (n = 100) and female (n = 381) university students. Administering self-report questionnaires, the authors assessed demographic information (gender, age), anthropometric data (Body Mass Index [BMI], age), romantic attachment (ECRS-R; R. C. Fraley, N. G. Waller, & K. A. Brennan, 2000), body dissatisfaction (BSQ), and disturbed eating (EAT-26). The authors found body dissatisfaction to fully mediate the relationship between attachment anxiety and disordered eating in women. Body dissatisfaction mediated anxious attachment and dieting in men. In addition, attachment avoidance had a direct impact on eating behaviors for both genders, without the mediation of any variables measured in this study. The findings of the present study suggest that the anxiety and avoidance dimensions of attachment insecurity affect eating behaviors differently, and the effects are different across genders. The authors discuss results in the context of therapeutic interventions design. PMID:20806850

    The purpose of this study was to examine longitudinal connections among young adolescent heterosocial involvement (i.e., mixed-sex interactions), peer pressure for thinness, and body dissatisfaction. Three years of self-report questionnaire data were collected from 88 adolescent girls as they completed 6th through 8th grades. Results indicated that the relation between heterosocial involvement and body dissatisfaction was mediated by perceived peer pressure for thinness. Within this model, heterosocial involvement was associated with greater peer pressure for thinness. In turn, peer pressure for thinness was associated with greater body dissatisfaction. Results are discussed in terms of their implications for prevention and intervention efforts aimed at girls during their middle-school years. PMID:21354882

    Silhouette measures are one approach to assessing body dissatisfaction in children, although little is known about their use among racially diverse, overweight girls seeking weight-loss treatment. This study assessed racial differences in body dissatisfaction and body size perceptions of 58 girls (ages 6–11, 66% Black, 34% White) participating in a randomized trial for pediatric overweight. Body dissatisfaction did not differ between races; 99% of girls reported an ideal figure smaller than their current one. Black girls selected a larger silhouette to represent their ideal body size, and most girls in both racial groups underestimated their actual size. Outcomes strengthen the argument that, despite an overall preference for a larger body size, obesity might mitigate cultural factors that protect Black girls from body dissatisfaction. Additional research is needed to enhance understanding of children’s body size perceptions and dissatisfaction to inform assessment and treatment of pediatric obesity and associated disordered eating symptoms.

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

    The fat talk literature is meager in terms of offering theoretical explanations for women's self-disparaging communication. The research presented here sought to establish a relationship between three prominent body image theories - self-discrepancy theory, social comparison theory, and objectification theory - and fat talk by proposing body dissatisfaction as a potential mediating mechanism. Young adult women (N=201) completed an online questionnaire. As predicted, results revealed that body dissatisfaction significantly mediated the relationships between weight discrepancy, upward comparison, body surveillance and fat talk. Effect size estimates indicated that the size of each indirect effect was medium in magnitude. PMID:24958666

    2015-04-01

    The purpose of this study was to investigate the hypothesis that the effect of body dissatisfaction on disordered eating behavior is mediated through self-esteem and depression. If the effect of body dissatisfaction on disordered eating can be explained by self-esteem and depression, treatment may benefit from focusing more on self-esteem and depression than body dissatisfaction. We also hypothesized body image importance to be associated with lower self-esteem, stronger symptoms of depression, and more disordered eating. The results showed that the effect of body dissatisfaction on disorder eating was completely mediated, whereas the effect of body image importance was partly mediated. Both self-esteem and depression were significant mediators. Body image importance and self-esteem had a direct effect on restrained eating and compensatory behavior. Depression had a direct effect on binge eating. This effect was significantly stronger among women. Depression also had a direct effect on restrained eating. This effect was positive among women, but negative among men. The results support emotion regulation and cognitive behavioral theories of eating disorders, indicating that self-esteem and depression are the most proximal factors, whereas the effect of body dissatisfaction is indirect. The results point out the importance of distinguishing between different symptoms of bulimia. Depression may cause binge eating, but compensatory behavior depends on self-esteem and body image importance. The results suggest that women may turn to both binge eating and restrained eating to escape awareness of negative emotions, whereas men focus on eating to a lesser extent than women. Existing treatment focuses on eating behavior first and mechanisms such as self-esteem and depression second. The results from this study suggest that an earlier focus on self-esteem and depression may be warranted in the treatment of disordered eating. PMID:25574864

    Experimental studies have demonstrated that exposure to idealized images of women increases state body image disturbance. However, little work has experimentally examined the effects of exposure to images that sexually objectify women, especially as it relates to women and men's state body dissatisfaction and judgments of women. In the current study, 437 women and men were randomly assigned to view advertisements that sexually objectify women and portray appearance ideals, or to view non-appearance-related advertisements. Results indicated that state body dissatisfaction increased for women and men exposed to advertisements that sexually objectified women, although this effect was larger for women. Trait internalization of appearance ideals moderated this effect, indicating that women and men with higher internalization exhibited greater state body dissatisfaction after viewing women sexually objectified in advertisements. Exposure to women sexually objectified in advertisements did not affect women's or men's attractiveness or competence ratings of women in university advertisements. PMID:26363356

    The body image of pregnant women is an issue that should be further investigated by professionals in the area, especially in view of the fact that maternal and infant health has gained such prominence. The scope of this integrative review is to analyze the literature relating to body image and body dissatisfaction among pregnant women. Research was based on articles extracted from the Scopus, PubMed, BVS and PsycINFO databases, by cross-referencing "pregnancy" with the keywords "body image" and "body dissatisfaction." Once the inclusion and exclusion criteria had been adopted, forty studies were analyzed. These produced inconclusive data about body dissatisfaction during pregnancy. Symptoms of depression, low self-esteem, an inadequate approach towards healthy eating and weight gain above recommended limits have been associated with a negative body image. The contradictory findings could be related to the different instruments used to measure body image. In view of the possible impact that a negative body image can have on maternal and infant health during pregnancy, it is recommended that further investigations are made, in particular related to the development of a specific tool to evaluate the body image of pregnant women.

    Recent proposals across a number of Western countries have suggested that idealised media images should carry some sort of disclaimer informing readers when these images have been digitally enhanced. The present studies aimed to experimentally investigate the impact on women's body dissatisfaction of the addition of such warning labels to fashion magazine advertisements. Participants were 120 and 114 female undergraduate students in Experiment 1 and Experiment 2 respectively. In both experiments, participants viewed fashion magazine advertisements with either no warning label, a generic warning label, or a specific more detailed warning label. In neither experiment was there a significant effect of type of label. However, state appearance comparison was found to predict change in body dissatisfaction irrespective of condition. Unexpectedly, trait appearance comparison moderated the effect of label on body dissatisfaction, such that for women high on trait appearance comparison, exposure to specific warning labels actually resulted in increased body dissatisfaction. In sum, the present results showed no benefit of warning labels in ameliorating the known negative effect of viewing thin-ideal media images, and even suggested that one form of warning (specific) might be harmful for some individuals. Accordingly, it was concluded that more extensive research is required to guide the most effective use of disclaimer labels. PMID:22947622

  14. Can the impact of body dissatisfaction on disordered eating be weakened by one's decentering abilities?

    PubMed

    Palmeira, Lara; Trindade, Inês A; Ferreira, Cláudia

    2014-08-01

    Decentering has been defined as the ability to deal with thoughts and emotions as subjective and ephemeral inner events. Since it implies a non-judging and present focused attitude towards thoughts and emotions, decentering has been considered as an important protective process against psychopathology, as it has been empirically shown to decrease depressive relapse rates. Nevertheless, its role in eating disordered attitudes and behaviours has not been fully uncovered. Therefore, the aim of the present study is to explore the moderator effect of decentering on the relationship between eating psychopathology and one of its main risk factors, body image dissatisfaction. The sample comprised 279 female students, aged between 14 and 21 years-old. Results revealed that decentering abilities were negatively linked to body image dissatisfaction and to the global score of eating psychopathology. Through a path analysis, the buffer effect of decentering was confirmed. The findings suggest that the ability to take a non-judgmental and accepting stance towards internal experiences diminishes the impact of one's body dissatisfaction on disordered eating attitudes and behaviours. This study seems especially pertinent since it uncovers a mechanism to lessen the pervasive impact of body image dissatisfaction, which is highly prevalent in women from Western societies.

In 2009, Cheng and Mallinckrodt proposed a dual mediation model, positing that poor-quality parental bonds, via the mechanisms of…

    Proponents of the sociocultural model of eating disorders have suggested that ethnic differences in body dissatisfaction may be diminishing as the thin ideal of beauty becomes more widely disseminated among minority women. In a meta-analysis, the authors examined temporal trends in Black-White differences and also examined whether these…

  1. From body dissatisfaction to obesity: how virtual reality may improve obesity prevention and treatment in adolescents.

    2013-01-01

    Different studies, including longitudinal studies, suggest a link between body dissatisfaction, unhealthful weight-control behaviors and obesity in both male and female adolescents. Here we suggest that body dissatisfaction in obese adolescents may be driven by an allocentric negative body image that is no more updated by contrasting egocentric representations driven by perception. In other words, subjects are locked to an allocentric negative representation of their body (allocentric lock hypothesis - http://dx.doi.org/10.1016/j.mehy.2011.10.039) that their sensory inputs are no more able to update even after the dramatic body changes following a successful diet. More, the possible role of virtual reality in the prevention and treatment of obesity in adolescence is presented and discussed. PMID:23400184

  2. Effects of a physical exercise session on state body image: The influence of pre-experimental body dissatisfaction and concerns about weight and shape.

    2009-07-01

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

    The current study was an investigation of the self-schema and social comparison theories of body dissatisfaction. The social comparison manipulation consisted of exposure to one of three levels of comparison figure: upward, downward, or no comparison. Two different imagery exercises served to prime either a participants' appearance self-schema, or a non-appearance schema. Participants completed state measures of body image and mood at pre- and posttest. Results indicated no significant interaction between priming and social comparison and no significant main effect for priming. However, there was a significant effect of social comparison, such that those in the downward comparison condition showed an increase in body satisfaction and positive mood. Results are discussed in the context of self-schema theory and social comparison, and suggestions are given for future research that might further shed light on these theoretical approaches for understanding body dissatisfaction.

    Gratitude has robust associations with multiple aspects of well-being. However, little research has explored whether the psychological benefits of gratitude extend to body image. We used a repeated measures experimental design to test whether a brief period of grateful reflection would buffer the adverse effect of exposure to thin-ideal media. Female undergraduates (N=67) completed three sessions one week apart. The conditions were specifically designed to isolate (a) the effects of viewing thin models on body dissatisfaction and (b) the moderating effect of grateful contemplation. Results showed that body dissatisfaction scores were lower for women who engaged in a brief period of grateful contemplation before viewing photographs of thin models than for women who reflected upon life hassles before viewing the same photographs. The magnitude of this decrease depended on BMI. Gratitude offers an innovative direction for future research directed toward helping women to accept their bodies. PMID:24958659

    Body dissatisfaction is particularly prevalent during adolescence and has recently been linked to stress in females and males. However, prospective studies are needed to better understand the relationship between stress and body dissatisfaction. The present study investigates the direction of this association and the mediating role of self-esteem and body image importance. A sample of 298 adolescent females and males in Grades 7 to 10 (ages 12 to 17 years) were surveyed at two time points over a one-year period. Hierarchical regression analyses revealed that stress significantly predicted body dissatisfaction one year later. Furthermore, a multiple mediation analysis controlling for gender revealed a significant indirect effect in both cross-sectional and longitudinal models, indicating that stress predicts reductions in self-esteem and increases in body importance, which in turn predict body dissatisfaction. These findings suggest that stress, self-esteem, and body importance should be included in programmes aimed at improving body dissatisfaction. PMID:23993480

    Introduction. The purpose of this study was to examine linkages between obesity, physical activity, and body image dissatisfaction, with consideration of socioeconomic status (SES) and urbanization in adolescents in Botswana. Materials and Methods. A nationally representative, cross-sectional survey in 707 secondary school students included measured height and weight to determine overweight (OW) or obesity (OB) using World Health Organization standards; physical activity (PA) using the International Physical Activity Questionnaire; and body image satisfaction using the Body Ideals Questionnaire. SES was described by private school versus public school attendance. Results and Discussion. OW/OB students felt farther from ideal and greater dissatisfaction with their weight and body proportions than optimal weight students. Boys felt greater difference from ideal and more dissatisfaction with muscle tone, chest size, and strength than girls. Lower SES students and those from rural villages had more minutes of PA than higher SES or urban students. In this rapidly developing African country, these trends reflect the nutrition transition and offer opportunity to motivate OW/OB students and boys for PA as a health promotion obesity prevention behavior. Conclusions. As urbanization and improved SES are desirable and likely to continue, the public health system will be challenged to prevent obesity while preserving a healthy body image.

    Women with high body dissatisfaction look less at their 'beautiful' body parts than their 'ugly' body parts. This study tested the robustness of this selective viewing pattern and examined the influence of positive body exposure on body-dissatisfied women's attention for 'ugly' and 'beautiful' body parts. In women with high body dissatisfaction (N = 28) and women with low body dissatisfaction (N = 14) eye-tracking was used to assess visual attention towards pictures of their own and other women's bodies. Participants with high body dissatisfaction were randomly assigned to 5 weeks positive body exposure (n = 15) or a no-treatment condition (n = 13). Attention bias was assessed again after 5 weeks. Body-dissatisfied women looked longer at 'ugly' than 'beautiful' body parts of themselves and others, while participants with low body dissatisfaction attended equally long to own/others' 'beautiful' and 'ugly' body parts. Although positive body exposure was very effective in improving participants' body satisfaction, it did not systematically change participants' viewing pattern. The tendency to preferentially allocate attention towards one's 'ugly' body parts seems a robust phenomenon in women with body dissatisfaction. Yet, modifying this selective viewing pattern seems not a prerequisite for successfully improving body satisfaction via positive body exposure. PMID:27236075

    Previous research has shown that adolescent girls tend to resemble their friends in their level of body dissatisfaction and disordered eating. However, no studies to date have attempted to disentangle the underlying peer selection and socialization processes that may explain this homophily. The current study used longitudinal stochastic actor-based modeling to simultaneously examine these two processes in a large community sample of adolescent girls (N = 1,197) from nine Australian girls' high schools. Friendship nominations and measures of body dissatisfaction, dieting and bulimic behaviors were collected across three annual waves. Results indicated that selection rather than socialization effects contributed to similarity within friendship groups when both processes were examined simultaneously. Specifically, girls tended to select friends who were similar to themselves in terms of body dissatisfaction and bulimic behaviors, but dissimilar in terms of dieting. Network and individual attribute variables also emerged as significant in explaining changes in adolescents' friendships and behaviors. As well as having important clinical implications, the findings point to the importance of controlling for friendship selection when examining the role of peers in adolescent body image and eating problems.

    A meta-analysis was conducted to determine the relationship between appearance and weight-based teasing and three outcome measures: body dissatisfaction, restrictive eating, and bulimic behaviors. Four meta-analyses were conducted. Fifty effect sizes (N=10,618) resulted in a moderate effect size of .39 for the relationship between weight teasing and body dissatisfaction; 24 effect sizes (N=7190) resulted in an effect size of .32 for the relationship between appearance teasing and body dissatisfaction; 20 effect sizes (N=4792) resulted in an effect size of .35 for the relationship between weight teasing and dietary restraint; and 22 effect sizes (N=5091) resulted in an effect size of .36 for the relationship between weight teasing and bulimic behaviors. Significant moderators that emerged were teasing measure type, publication type, study type, age group, and gender. The findings offer further support for the inclusion of strategies in body image and eating disorders' prevention and intervention programs that focus on handling negative, appearance-related commentary.

    Introduction Body dissatisfaction (BD), a risk factor for eating disorders, is occurring at younger ages and among a wide range of socioeconomic and cultural groups. Objective To describe body ideals and prevalence of body satisfaction among an ethnically diverse population of male and female students in Hawaii. Methods An anonymous cross-sectional survey including biographical information and the figure drawing screen was distributed to 7th through 12th grade students. Results Of the 1330 completed surveys, 19% of students were significantly dissatisfied with their bodies. Males were at greater risk than females for total BD (25.8% vs. 13.3%; p<0.001) and for BD in the direction of wanting to be larger (11.3% vs. 2.3%; p<0.001). Males and females were at similar risk for BD in the direction of wanting to be thinner (14.6% vs. 11.6%; p=0.11). Prevalence of BD in the direction of wanting to be thinner was significantly different (p<0.05) among ethnic groups. There were no significant differences in BD based on grade level or SES. Conclusions BD exists among nearly 1 out of 5 adolescents, with differing patterns for males and females, and with certain ethnic groups being at higher risk. Implications Studies to understand risk and protective factors by sex and among different ethnic groups may help generate tailored prevention strategies. Further research is needed to better understand the mechanisms underlying the bidirectional BD seen in males and potential outcomes.

    2013-06-01

    This study examined in young adolescent girls the fit of a theoretical model of the contribution of media literacy to body dissatisfaction via the mediating influences of internalisation of media ideals and appearance comparisons. Female Grade 7 students (N=469) completed self-report assessments of media literacy, internalisation, appearance comparisons, body dissatisfaction, and media exposure. Strong, significant inverse associations between media literacy and body dissatisfaction, internalisation, and appearance comparisons were observed. Path analysis revealed that a slightly modified revision of the model provided a good fit to the data. Specifically, body dissatisfaction was influenced directly by appearance comparisons, internalisation, and body mass index, and indirectly by media literacy and media exposure. Indirect pathways were mediated by appearance comparisons and internalisation. Thus, a relationship between media literacy and eating disorder risk factors was observed. Findings may explain positive outcomes of media literacy interventions in eating disorder prevention. PMID:23465878

    2014-01-01

    The consistent use of condoms is the most effective behavior for reducing the acquisition of sexually transmitted infections (STIs), and condom use self-efficacy has been shown to be a key construct related to condom use. However, the examination of modifiable psychosocial and behavioral correlates of condom use self-efficacy is lacking. Recent investigations have highlighted the association of body dissatisfaction with condom use self-efficacy, and the current study conducted a meta-analysis on all available data addressing this relationship. Eleven individual effect-size parameters from nine studies yielded a total sample of 2,495 men and women participants. A random-effects model revealed an average effect-size of r = −0.25, Cohen’s d = −0.52, which is moderate in strength. As body dissatisfaction increases, ones’ self-efficacy regarding the use of condoms diminishes. Integrating interventions to decrease body dissatisfaction and sexual risk behaviors may prove to be an effective strategy to decrease STIs. PMID:25462884

    Body dissatisfaction and dieting are risk factors for eating disorders. Understanding young people's views about factors underlying body dissatisfaction and dieting may be helpful for those designing preventative interventions. This study explored adolescents' views on causes of body dissatisfaction and dieting and recommendations for prevention. Four 1-h focus groups were conducted with 22 female adolescents (aged 13-15 years). Transcripts were explored using thematic analysis. Body dissatisfaction and dieting was explained by four themes: peer acceptance; social comparison online; pressure from family; and pressure from the media and fashion industries. There were seven areas of recommendation for prevention: building sources of support; learning to be critical of the media; monitoring the school gym; working with parents; educating about signs and symptoms of eating disorders; working with people who have suffered from eating disorders; and providing help from professionals. Implications of these findings for the development of prevention programmes are discussed. PMID:23760841

    Internalization of the thin ideal mediates the media exposure-body dissatisfaction relation in young adult European American females. There is little related research on Asian Americans. We used structural equations modeling to test: (1) whether media exposure was associated with body dissatisfaction in Asian American young adult females, (2) internalization of the thin ideal mediated any such association, and (3) whether the mediational model provided equivalent fit for European American and Asian American samples. Participants were 287 college females (154 Asian Americans, 133 European Americans). Internalization of the thin ideal explained the media exposure-body dissatisfaction association equally well for both groups. Results suggest that Asian Americans may be employing unhealthy weight control behaviors, and may be prone to developing eating disorders, at rates similar to European American young adult females. Clinicians need to screen carefully for body dissatisfaction, unhealthy weight control behaviors, and eating disorders in Asian American females. PMID:21775227

    The aim of this study was to situate adolescent girls' body dissatisfaction, disordered eating, and self-esteem in the context of their life concerns and leisure activities. Questionnaires containing measures of life concerns, leisure activities, body dissatisfaction, disordered eating, and self-esteem were administered to 306 girls with a mean age of 16 years. It was found that although academic success and intelligence were rated as the most important life concerns, an emphasis on slimness was most strongly linked to body dissatisfaction, disordered eating, and global self-esteem. An emphasis on popularity with girls also was related to body dissatisfaction, and hours spent watching television were related to lower self-esteem. In contrast, emphasis on sport seemed to serve a protective function. It was concluded that adolescent girls who have a high concern for slimness should be assisted in decreasing this emphasis in order to improve their general well-being. PMID:11432599

    Internalization of societal standards of physical attractiveness (i.e., internalization of the thin ideal for women and internalization of the mesomorphic ideal for men) is a widely studied and robust risk factor for body dissatisfaction and maladaptive body change behaviors. Substantial empirical research supports internalization as both a mediator and a moderator of the relation between societal influences and body dissatisfaction. In this paper, a primer on mediation and moderation is followed by a review of literature and discussion of the extent to which internalization can theoretically fulfill the roles of both mediation and moderation. The literature review revealed a stark contrast in research design (experimental versus non-experimental design) when alternate conceptualizations of internalization are adopted. A meta-theoretical, moderated mediation model is presented. This model integrates previous research and can inform future empirical and clinical endeavors. PMID:23871195

    The authors designed the present study to test whether women reported higher levels of body dissatisfaction than did men even when the 2 genders were matched on a measure of degree of body focus. Sixty undergraduates (30 men, 30 women) were screened on attention-to-body-shape scores and divided into high, medium, and low body-shape-focus groups. The participants also completed questionnaires that provided information on age, education, vocabulary ability, levels of depression, and body-image assessment. The groups did not differ (ps > .05) on age, education, vocabulary ability, or levels of depression. However, women in all 3 body-shape-focus categories indicated a larger discrepancy between their real vs. ideal body images (p < .01) than did the men. In the high-body-focus group, there was an 11:1ratio between women's and men's reported real-ideal body-shape discrepancies. Women showed greater body dissatisfaction than did men, even when the genders were matched on a measure of body focus. PMID:12926515

    2016-03-01

    The tripartite model has been an important and empirically supported theoretical model positing that the influence of peers, family, and media leads women to internalise the thin societal body ideal. This internalisation in turn leads women to experience body dissatisfaction. Recently, a new societal 'athletic ideal' for women has emerged, which promotes a body frame with pronounced lean muscle mass. This study tested the role of the athletic ideal in the tripartite model of influence with a sample of 421 women aged 17-40 years. Athletic ideal internalisation was neither found to be associated with body dissatisfaction, nor act as a mediator in the relationship between sociocultural influences and body dissatisfaction. Although more research is required, the results of this study suggest that for this cross-sectional sample of women, internalisation of an athletic and muscular, rather than thin ideal, may be less detrimental to body satisfaction.

    2013-01-01

    Background In order to elucidate the individual and community health burden of body dissatisfaction (BD), we examined impairment in quality of life associated with BD in a large, general population sample of women. Methods Self-report measures of BD, health-related quality of life (SF-12 Physical and Mental Component Summary scales) and subjective quality of life (WHOQOL-BREF Psychological Functioning and Social Relationships subscales) were completed by 5,255 Australian women aged 18 to 42 years. Results Most participants (86.9%) reported some level of dissatisfaction with their weight or shape and more than one third (39.4%) reported moderate to marked dissatisfaction. Higher levels of BD were associated with poorer quality of life for all items of both quality of life measures, the degree of impairment being proportional to the degree of BD. Associations were strongest for items tapping mental health and psychosocial functioning, although greater BD was associated with substantially increased risk of impairment in certain aspects of physical health even when controlling for body weight. Post-hoc analysis indicated that the observed associations between BD and quality of life impairment were not accounted for by an association between BD and eating disorder symptoms. Conclusions In women, BD is associated with marked impairment in aspects of quality of life relating to mental health and psycho-social functioning and at least some aspects of physical health, independent of its association with body weight and eating disorder symptoms. Greater attention may need to be given to BD as a public health problem. The fact that BD is “normative” should not be taken to infer that it is benign. PMID:24088248

    Deliberate self-harm (DSH) is a common though often hidden condition in children and adolescents that may result in suicide. This discussion covers several aspects of DSH including its prevalence, etiology, and management. The relationships of DSH to body dissatisfaction and suicide are specifically considered. Even though most cases of DSH do not end in overt suicide, DSH reflects that potential underlying psychological pathophysiology, and likelihood of eventual death from self-murder, cannot always be predicted or prevented. It is important to take all acts of DSH as serious, and to offer comprehensive management to prevent future acts of DSH and potential suicide. PMID:21811385

    Objective The relationship between Islamic veiling, body dissatisfaction and desire for cosmetic rhinoplasty (CR) has not been studied. We therefore compared body dissatisfaction (BD), depression, self-esteem, and prevalence and desire to have CR in 1771 Iranian females. Method A battery of questionnaires was administered and participants were categorized into three groups of Islamic veil practicing: voluntarily and ideologically (IVP), non-complete (NCIVP) and Inconsiderate (IIVP). Results Despite a similar BMI, the IVP group scored significantly lower on BD, prevalence of dieting and exercising in order to be sexually appealing, and depression, higher on self-esteem, and had a lower desire for a CR than the two other groups. Prevalence of CR was significantly higher in the IIVP group than the other groups. Conclusions Women who practiced more strict Islamic veiling techniques had increased body satisfaction and self esteem, and decreased depression scores and desire for CR. Consistent with other studies, our findings show that observance of a strict religious practice has a protective effect on psychological health. PMID:19115373

    A pilot study was carried out in university students to evaluate the effect of a health promotion program for eating disturbances and body dissatisfaction. A subgroup of 135 medical students of both sexes in their second year was selected. There were divided in three groups, high-risk students (EDI >40) and low-risk students (EDI <40) who participated in the program and nonparticipants as comparison group. Program had a total of 16 workshops of 90 min. A year later the different assessment measurements were compared, body image, attitudes and eating behaviours, psychopathological levels and self-esteem. Differences by gender were found on the impact of the intervention. The program presented a statistical significant improvement in body-image satisfaction, eating attitudes only in high-risk female students in the intervention group. This pilot program for eating disorder prevention in university populations can be considered effective, mainly in female populations at risk for developing an eating disorder. PMID:18089278

    The aim of this study was to explore the differences in patterns of risk factors for body dissatisfaction and disordered eating attitudes in both female and male adolescents from Portugal and Spain. The sample included 455 adolescents aged 12-16 years (M = 13.28, SD = 0.65) from two urban areas of each country. Body mass index, self-reported self-esteem, perfectionism, internalisation of sociocultural ideals, body dissatisfaction and disordered eating attitudes were assessed. Path analyses provided partial support for a cross-cultural model of body dissatisfaction and disordered eating in Western countries due to the presence of certain differences in the patterns of relationships across sex and country. The findings suggest the importance not only of identifying cultural specificities, even in "neighbouring" countries, but also of developing a global and comprehensive preventive approach that focuses on the influence of the ideal of beauty transmitted by Western societies.

    This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=−0.19; p<0.01) and that higher body mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=−0.17, p<0.01) only in non-practitioners. The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η2=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η2=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group. PMID:25713641

    This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant.

The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η(2)=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η(2)=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance.

    European American (EA) women report greater body dissatisfaction and less dietary control than do African American (AA) women. This study investigated whether ethnic differences in dieting history contributed to differences in body dissatisfaction and dietary control, or to differential changes that may occur during weight loss and regain. Eighty-nine EA and AA women underwent dual-energy X-ray absorptiometry to measure body composition and completed questionnaires to assess body dissatisfaction and dietary control before, after, and one year following, a controlled weight-loss intervention. While EA women reported a more extensive dieting history than AA women, this difference did not contribute to ethnic differences in body dissatisfaction and perceived dietary control. During weight loss, body satisfaction improved more for AA women, and during weight regain, dietary self-efficacy worsened to a greater degree for EA women. Ethnic differences in dieting history did not contribute significantly to these differential changes. Although ethnic differences in body image and dietary control are evident prior to weight loss, and some change differentially by ethnic group during weight loss and regain, differences in dieting history do not contribute significantly to ethnic differences in body image and dietary control.

    Theory and research suggest that sociocultural pressures, thin-ideal internalization, and self-objectification are associated with body dissatisfaction, while feminist beliefs may serve a protective function. This research examined thin-ideal internalization and self-objectification as mediators and feminist beliefs as a moderator in the relationship between sociocultural pressures to meet the thin-ideal and body dissatisfaction. Female undergraduate volunteers (N=195) completed self-report measures assessing sociocultural influences, feminist beliefs, thin-ideal internalization, self-objectification, and body dissatisfaction. Multisample structural equation modeling showed that feminist beliefs moderate the relationship between media awareness and thin-ideal internalization, but not the relationship between social influence and thin-ideal internalization. Research and clinical implications of these findings are discussed. PMID:18089276

    This longitudinal study aims to describe the development of body dissatisfaction (BD), measured with the Contour Drawing Rating Scale, between the ages of 14 and 18, and to identify factors associated with BD at age 18, among 413 adolescents. Between the ages of 14 and 18, the proportion of girls wanting to be thinner increased, although it remained unchanged among boys. A ratio of 1:2 girls and 1:5 boys reported having seriously tried to lose weight. Factors associated with BD in girls at age 18 were (1) wanting to be thinner, (2) body mass index (BMI), (3) weight control behaviours and (4) negative comments about weight. Factors associated with BD in boys at age 18 were (1) wanting to be thinner or bigger, (2) BMI, (3) having experienced sexual intercourse and (4) negative comments about weight. The high prevalence of BD and weight-related concerns suggest a need for early interventions. PMID:25931646

    Preadolescence is a key period in the early stages of eating disorder development. The aim of the present study was, firstly, to investigate restrained, emotional and external eating in a general population-based sample of 11-12 year olds. Secondly, we sought to explore how these eating behaviours are associated with possible predictors of eating disorders, such as body dissatisfaction, weight status and mental disorders. A subsample of 1567 children (47.7% boys; 52.3% girls) from the Copenhagen Child Cohort (CCC2000) completed web-based questionnaires on eating behaviours and body dissatisfaction using The Eating Pattern Inventory for Children (EPI-C) and The Children's Figure Rating Scale. Mental disorders were assessed using the online version of the Development and Well-Being Assessment (DAWBA) based on parental replies with final DSM-IV diagnoses determined by experienced child- and adolescent psychiatrists. Height and weight were measured at a face-to-face assessment. The results showed that restrained eating was significantly associated with overweight, body dissatisfaction and emotional disorders in both genders. Emotional eating showed similar associations with overweight and body dissatisfaction in both genders, but was only associated with mental disorders in girls. External eating was significantly associated with body dissatisfaction and neurodevelopmental disorders in both genders, but was only associated with overweight in girls. Our findings show that problematic eating behaviours can be identified in preadolescence, and co-exist with weight problems and mental disorders. Thus restrained, emotional and external eating was, in different ways, associated with overweight, body dissatisfaction and mental disorders. Our findings point to significant eating behaviours in preadolescence, which could constitute potential predictors of later eating disorder risk. PMID:26896837

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

    The developmental path leading to eating disorders among adolescent girls often proceeds from increasing body size, to increasing body dissatisfaction, to increasing ED risk. To determine whether body dissatisfaction (BD) mediates the association between body size and risky weight control behaviors, we examined data from White (n = 709) and Native American (n = 253) girls, who differ substantially in terms of average body mass and reported weight control behaviors. Measures of BD included weight, shape, and appearance concerns. Measures of ED-risk included dieting, exercising to control weight, binge eating, and vomiting. Results showed body dissatisfaction was a highly significant mediator of the relationship between BMI and ED risk for both ethnic groups; although BD did not mediate the association between BMI and binge eating for either group. BD is apparently an important mediator of the association between body size and some, but not all, risky weight control behaviors. PMID:18342990

    Although attentional biases toward body-related information contribute to the etiology and maintenance of body dissatisfaction (BD) and eating disorders (EDs), attentional disengagement in women with BD and EDs is not clear. The present study investigated the association between weight dissatisfaction and attentional disengagement from body-related pictures and the possible moderating effect of body mass index (BMI) on this relation. Two hundred and four undergraduate women engaged in an experiment using a pictorial spatial cueing paradigm including fat/thin bodies and neutral household photos. Partial correlations and simple slopes regression analyses were conducted with attentional disengagement index scores of each category of cues. Findings suggested that independent of BMI, weight dissatisfaction was directly associated with attentional disengagement from both fat and thin pictures. In addition, among women with low and medium BMIs, the more they were dissatisfied with their bodyweight, the more difficulty they had disengaging their attention from fat body pictures.

    Thinking negatively about one's appearance may be a major source of unhappiness. It was investigated whether the habitual quality of negative body image thinking constitutes an additional vulnerability factor, i.e. when such thinking is repetitive and automatic. The cognitive content of negative body image thinking ('what') was distinguished from the habitual occurrence of such thinking ('how'). The mental habit component uniquely predicted explicit as well as implicit body dissatisfaction (the latter measured by an implicit association test) over and above cognitive content. Mental habit also accounted for eating disturbance propensity, low self-esteem and restrained snacking behaviour over and above cognitive content, even when controlled for body dissatisfaction. The habitual component of negative thinking about appearance thus seems a significant body image construct, has discriminant validity against body dissatisfaction, and constitutes a vulnerability factor for feelings of low self-worth and eating disturbance propensity. Implications for intervention strategies, such as mindfulness-based approaches, are discussed. PMID:21347977

    Sociocultural models of disordered eating lack comprehensive explanations as to how thin ideal internalization leads to body dissatisfaction. This study examined two social psychological theories as explanations of this relation, namely social comparison and objectification theories, in a sample of 265 women attending a Southeastern university. Social comparison (both general and appearance-related) and body surveillance (the indicator of objectification) were tested as mediators of the relation between thin ideal internalization and body dissatisfaction using bootstrapping analyses. Results indicated that body surveillance was a significant specific mediator of this relation; however, neither operationalization of social comparison emerged as such. Results serve to elaborate upon the sociocultural model of disordered eating by providing a more comprehensive understanding of the processes by which thin ideal internalization manifests itself in body dissatisfaction. The current findings also highlight the importance of targeting body surveillance in clinical settings. PMID:21992811

    The objective was to explore what predicts first-year college women's disordered eating tendencies when they arrive on campus. The 215 first-year college women completed the surveys within the first 2weeks of classes. A structural model examined how much the Helplessness, Hopelessness, Haplessness Scale, the Brief COPE, the Brief College Student Hassle Scale, and the Body Shape Questionnaire predicted eating disordered tendencies (as measured by the Eating Attitudes Test). The Body Shape Questionnaire, the Helplessness, Hopelessness, Haplessness Scale (inversely), and the Denial subscale of the Brief COPE significantly predicted eating disorder tendencies in first-year college women. In addition, the Planning and Self-Blame subscales of the Brief COPE and the Helplessness, Hopelessness, Haplessness Scale predicted the Body Shape Questionnaire. In general, higher levels on the Helplessness, Hopelessness, Haplessness Scale and higher levels on the Brief College Student Hassle Scale related to higher levels on the Brief COPE. Coping seems to remove the direct path from stress and depression to disordered eating and body dissatisfaction. PMID:25528718

    This study identified longitudinal risk factors for body dissatisfaction (BD) over a 10-year period from adolescence to young adulthood. Participants (N = 2134; age at baseline: M =15.0, SD =1.6 years) provided two waves of survey data. A 6-step hierarchical linear regression analysis examined the predictive contribution of Time 1 BD, weight status, demographics, family and peer environmental factors, and psychological factors. Among females, Asian race/ethnicity, low self-esteem, greater BD, and higher body mass index during adolescence contributed significantly to predicting greater BD at 10-year follow up (R2 = 0.27). Among males, demographics (i.e., Asian, other-mixed ethnicity, education attainment), depressive symptoms, greater BD, higher body mass index, more parent communication, and less peer weight teasing during adolescence contributed to BD at follow-up (R2 = 0.27). Findings indicate who may be at greatest risk for BD in young adulthood and the types of factors that should be addressed during adolescence. PMID:25045599

    The aim of the study was to compare levels of body dissatisfaction, disordered eating and risk factors, and to examine the tripartite influence model of body image and eating disturbance among French and Australian young adult females. Participants were 188 Australian (mean age=19.6 years, SD=1.0) and 190 French (mean age=20.7 years, SD=2.6) students. Media, peer and family influences, internalisation of media ideals, appearance comparison, body dissatisfaction, drive for thinness, bulimia and self-esteem were assessed. Australian participants reported perceiving more peer and media influence, and higher levels of appearance comparison, internalisation of media ideals and bulimic symptoms than French participants (p<.001). Path analyses revealed that the tripartite model was a good fit in both samples, with similarities and differences. Findings suggest the importance of identifying cultural specificities, and developing a global framework of body image and eating disturbance with a view to prevention. PMID:21664887

    Previous correlational research indicates that adolescent girls who use social network sites more frequently are more dissatisfied with their bodies. However, we know little about the causal direction of this relationship, the mechanisms underlying this relationship, and whether this relationship also occurs among boys to the same extent. The present two-wave panel study (18 month time lag) among 604 Dutch adolescents (aged 11-18; 50.7% female; 97.7% native Dutch) aimed to fill these gaps in knowledge. Structural equation modeling showed that social network site use predicted increased body dissatisfaction and increased peer influence on body image in the form of receiving peer appearance-related feedback. Peer appearance-related feedback did not predict body dissatisfaction and thus did not mediate the effect of social network site use on body dissatisfaction. Gender did not moderate the findings. Hence, social network sites can play an adverse role in the body image of both adolescent boys and girls. PMID:25788122

    Although internalization of the thin ideal has been extensively researched and is now regarded as a risk factor for eating disturbance, endorsement of the firm, athletic body ideal has received only minimal attention. This short-term longitudinal study explored whether internalization of two aspects of the current cultural ideal (thinness and athleticism) prospectively predicted three potentially deleterious outcomes: body dissatisfaction, dieting, and compulsive exercise. Undergraduate women (N=231) completed self-report measures at the beginning of the academic year and again 7 months later (N=156 at Time 2). Athletic-ideal internalization predicted change in compulsive exercise over the 7-month study period but not body dissatisfaction or dieting; thin-ideal internalization predicted change in all three outcomes. When both internalization measures were tested simultaneously, neither contributed unique variance. Results suggest that athletic-ideal internalization is not as detrimental as thin-ideal internalization. PMID:20226748

    Although research has shown that perfectionism is associated with eating disorder pathology, the role of body dissatisfaction in this association is less clear. In this study, we examined the possible moderating and mediating role of body dissatisfaction in the relation between perfectionism and increases in eating disorder pathology. Both possible roles were tested in a sample of 455 adolescent girls (mean age = 13.25 years) using a 3-wave longitudinal study. We only found support for the moderation hypothesis, with girls high on both perfectionism and body dissatisfaction exhibiting the highest levels of eating disorder symptoms. Implications of these findings are discussed. PMID:24886015

    Existing literature fails to comprehensively identify factors contributing to the comorbid relationship between eating disorder (ED) behaviors and unipolar depression. Maladaptive social comparison, body dissatisfaction, and low self-esteem are disruptive psychological patterns common to both constructs. It is unclear whether a unique relationship exists between depression and eating disorder behaviors beyond the effects exerted by this negative cognitive triad. The purpose of the present study is to examine whether a unique relationship exists between depression and ED behaviors after controlling for maladaptive social comparison, body dissatisfaction, and low self-esteem. We predict minimal unique variance in ED behaviors will be explained by depression after controlling for this negative cognitive triad. PMID:19388056

    Background Weight and shape concerns are widespread in the general population. Mirror exposure has been used to reduce body dissatisfaction but little is known about the mechanisms which underlie this therapeutic technique. The present study examined emotional, cognitive, and psychophysiological responses, in women with high and low levels of body dissatisfaction, exposed to their own bodies in a mirror. Method Forty-two university-attending women (21 high body-dissatisfied (HBD) and 21 low body-dissatisfied (LBD)), were confronted with their own body during four 5-min trials in which participants were instructed to focus their attention on different parts of their body under standardized conditions. Emotional and cognitive measures were taken after each exposure trial. Heart rate (HR) and skin conductance (SC) were recorded continuously. Results HBD women experienced more negative emotions and cognitions following body exposure compared to LBD women but, conversely, showed a reduced physiological reaction in terms of HR and SC. In both groups greater physiological responses were observed looking at the thighs, buttocks, and abdomen. Extent of negative emotions and cognitions were positively associated with HR and/or SC in LBD women but no associations were observed in HBD women. Conclusion The dissociation between self-report and psychophysiological measures in HBD women supports the existence of a passive-behavioral inhibited coping style in HBD women and suggests deficiencies in the generation of physiological correlates of emotion related to body dissatisfaction.

    Measures of body dissatisfaction have not been validated for Mexican American (MA) women, who evaluate their bodies differently than Caucasian women. In this study, the psychometric properties of the EDI-III, Body Dissatisfaction Subscale (BDS) were examined in a sample of college-enrolled MA women using the Rasch Rating Scale Model. Criterion validity was also addressed. BDS evidenced good item fit, person and item reliability, once poorly correlated items were removed. Two qualitatively distinct dimensions of body dissatisfaction were identified: (1) overall body shape and stomach, and (2) the lower body. Validity of the scales was supported. Results suggest: MA women's satisfaction with overall body shape is not synonymous with attitudes toward their lower body. PMID:26164669

    With research highlighting the increasing prevalence and severity of body image and eating disturbances in males, particularly athletes and regular gymnasium users, the current study examined body image and eating disturbances in a sample of male gym users and non-gym users (N = 180). Based on previous research, it was predicted that male gym users would report greater body image disturbance (e.g., body image avoidance and body dissatisfaction) and eating pathology, compared with non-gym users. Results of the study partially supported hypotheses, revealing body dissatisfaction and eating pathology were significantly increased in male gym users. However, no significant differences were observed in body image avoidance behaviors, though this is likely because of methodological limitations associated with psychometric measures selected. The study provides preliminary evidence that male gym users do experience subclinical eating and body image concerns, with some also experiencing clinically significant symptoms that could be precursors to the later development of an eating disorder. Results of the current study highlight the importance of educating key stakeholders within health and fitness centers, through community-based interventions, to increase awareness regarding male body image and eating disturbances.

    Literature has demonstrated the negative impact of body image dissatisfaction on women's quality of life. Nonetheless, it has been suggested that the relationship between body dissatisfaction and women's well-being is not linear, and that the processes that mediate this association remain unclear. This study aims to clarify the mediator role of self-judgment in the association between negative body image and psychological quality of life, in two groups: normal-weight and overweight women. This cross-sectional study comprised 200 normal-weight and 92 overweight female college students, aged between 18 and 24 years old, that completed self-report instruments of body dissatisfaction, self-judgment, and quality of life. Results showed that women who presented harsher self-judgment about their perceived failures tended to present lower levels in all quality of life domains. Also, results from mediation analyses indicated the relationship between body dissatisfaction and psychological quality of life was significantly mediated by the mechanisms of self-judgment in the two BMI groups (95% CI [-2.41 to -0.04]; 95% CI [-6.35 to -.89]). This mediational model accounted for 28.3% and 40.7% of psychological quality of life in the normal-weight and overweight groups, respectively. These results suggest that a lower ability to deal with one's failures or inadequacies (e.g., negative evaluation of body image) in a kind and accepting manner may significantly increase the negative impact of body dissatisfaction on one's psychological quality of life. In this way, it seems that, the focus of interventions should go beyond body dissatisfaction and also target the development of adaptive attitudes (opposed to self-critical attitudes) to deal with negative body-related experiences.

    The relationships among acculturation, internalization of U.S. sociocultural standards of female beauty, and body dissatisfaction were examined in a sample of 211 Mexican American college women. Structural equation modeling was used to identify the paths among these three factors. Results demonstrated that there are two distinct types of body dissatisfaction: global evaluations and composite site-specific evaluations. The relationships between acculturation toward dominant U.S. culture and both types of body dissatisfaction were found to be fully mediated by internalization of U.S. standards of female beauty. There were no relationships between Mexican orientation and any of the study variables. The results from this study imply that it is important for therapists working with Mexican American female clients to assess the client's level of acculturation, examine the cultural (U.S. and Mexican) messages the client receives, and explore how these messages impact her body image.

  19. A prevention program for disturbed eating and body dissatisfaction in adolescent girls: a 1 year follow-up.

    PubMed

    Paxton, S J

    1993-03-01

    This study evaluated an intervention program to reduce moderate and extreme weight loss behaviors, disordered eating and low body image. The Body Image and Eating Behavior Intervention Program consisted of five specialized classes addressing media images of women, determinants of body size, healthy and unhealthy weight control methods, and emotional eating. The program was conducted in year 9 in Schools 1 (n = 80) and 2 (n = 27), while students from the same year in School 3 (n = 29) were control subjects. Participants completed self-report questionnaires assessing eating behavior and body image attitudes prior to the program, 1 months after the program and at 12 months follow-up, while control subjects completed the questionnaires at the same time but did not receive the program. Data were analyzed using groups (Schools 1, 2 and 3) by testing occasion (pre, post and follow-up) analyses of variance with repeated measures on testing occasion. Measures of disordered eating and frequency of use of extreme weight loss behaviors were constant over testing occasion and showed no effect of the intervention program. Body dissatisfaction was consistently lower in School 1 but increased across all subjects over the year. The implications of these data for school-based intervention programs in this area are examined. PMID:11067184

    2012-12-01

    Research has identified a relation between exposure to thin-ideal magazine and television media images and eating disorder pathology. However, few studies have examined the potential influence of Internet media on eating disorder behaviors and attitudes. This study investigated associations among image-focused media exposure, body dissatisfaction, eating pathology and thin-ideal internalization in a sample of 421 female undergraduates. Undergraduate women spent significantly more time viewing online appearance-oriented media, rather than reading image-focused magazines. Appearance-oriented Internet and television use were associated with eating pathology. Moreover, the association between image-focused Internet use and BD was mediated by thin-ideal internalization. These findings are consistent with those of previous research, and highlight the vulnerability individuals high in thin-ideal internalization might have to media exposure. They also suggest that Internet media use is an important topic to attend to in eating disorders prevention and treatment. PMID:23121797

    Exposure to media images of the 'body-perfect' ideal has been partly blamed for the pursuit of thinness among women and muscularity among men. Research has largely overlooked the materialistic messages frequently associated with these images. We present findings from two studies with Icelandic students aged 18-21, one focusing on young women (n = 303) and one on young men (n = 226), which test associations of materialistic and body-perfect ideals with body dissatisfaction and excessive body shaping behaviors. In both studies, the internalization of materialistic values is strongly linked to the internalization of body-perfect ideals: the thin-ideal for young women, and the muscular-ideal for young men. A materialist value orientation also predicted body dissatisfaction in both studies, and was linked to body shaping behaviors, albeit differently for young women and men. Thus, the research identifies materialism as a further correlate of both body dissatisfaction and excessive body-shaping behaviors. The findings support Dittmar's (2008) Consumer Culture Impact Model, which proposes that the body-perfect and 'material good life' ideals jointly impact well-being. PMID:24611622

    2016-03-01

    Mothers' influence on their daughters is important for understanding girls' disordered eating and body dissatisfaction. Direct maternal encouragement of daughters to lose weight is linked to daughters' development of bulimic symptoms, and additional findings indicate that daughters whose mothers merely talk about dieting and body dissatisfaction are more likely to be diagnosed with an eating disorder. The current study extends such research by examining the interactive contributions of maternal encouragement to lose weight and maternal dieting discussions to the prediction of early adolescent daughters' body dissatisfaction and disordered eating over the middle school period. Participants were 89 adolescent girls who were in the 6th grade at Time 1. Regression analyses were conducted to examine interactive effects of mother encouragement to diet and talk of weight concerns on daughter body dissatisfaction, drive for thinness, and dieting behavior. Results suggest an interactive effect in which mothers' dieting talk may act as a buffer against the negative effects of direct encouragement to lose weight. PMID:26551484

    The current study evaluated associations between sport-performance-related body dissatisfaction (BD), general-appearance-related BD, and their relation to EAT-26 scores among a sample of adult runners who participated in middle- and long-distance races in the northeastern United States (N=400, 46.5% male). Women reported elevated BD and eating disorder symptoms, as compared to men. Ridge regression was used to analyze correlations between appearance- and performance-related BD with EAT-26 scores. Results demonstrated that appearance- and performance-related BD positively correlated with EAT-26 scores in women (βs=0.18 and 0.13, respectively). Race length was a significant covariate for women, such that those who ran middle-distance race events were more likely to report higher EAT-26 scores (β=-3.12). These associations were not demonstrated in men. Results suggest that it is beneficial to address sport-specific body image concerns, in addition to more general appearance-related body image concerns in female runners. PMID:26952015

    The degree to which media contributes to body dissatisfaction, life satisfaction and eating disorder symptoms in teenage girls continues to be debated. The current study examines television, social media and peer competition influences on body dissatisfaction, eating disorder symptoms and life satisfaction in a sample of 237 mostly Hispanic girls. 101 of these girls were reassessed in a later 6-month follow-up. Neither television exposure to thin ideal media nor social media predicted negative outcomes either concurrently nor prospectively with the exception of a small concurrent correlation between social media use and life satisfaction. Social media use was found to contribute to later peer competition in prospective analysis, however, suggesting potential indirect but not direct effects on body related outcomes. Peer competition proved to be a moderate strong predictor of negative outcomes both concurrently and prospectively. It is concluded that the negative influences of social comparison are focused on peers rather than television or social media exposure. PMID:23344652

    2015-01-01

    Background and Aims Past research has examined eating disorder risk among college students majoring in Nutrition and has suggested an increased risk, while other studies contradict these results. Exercise Science majors, however, have yet to be fully examined regarding their risk for eating disorders and exercise dependence. Based on pressures to fit the image associated with careers related to these two disciplines, research is warranted to examine the potential risk for both eating disorder and exercise dependence. The purpose of this study is to compare eating disorder risk, exercise dependence, and body weight dissatisfaction (BWD) between Nutrition and Exercise Science majors, compared to students outside of these career pathways. Methods Participants (n = 89) were divided into three groups based on major; Nutrition majors (NUTR; n = 31), Exercise Science majors (EXSC; n = 30), and other majors (CON; n = 28). Participants were given the EAT-26 questionnaire and the Exercise Dependence Scale. BWD was calculated as the discrepancy between actual BMI and ideal BMI. Results The majority of participants expressed a desire to weigh less (83%) and EXSC had significantly (p = .03) greater BWD than NUTR. However, there were no significant differences in eating disorder risk or exercise dependence among majors. Discussion and Conclusions This study suggested there was no significant difference in eating disorder risk or exercise dependence between the three groups (NUTR, EXSC, and CON). PMID:26551912

    Objectives To learn about parent weight talk, parent dieting, and family weight-teasing in the homes of adolescent girls at risk for obesity and weight-related problems. To examine associations between these family variables and girls’ weight status, body satisfaction, and disordered eating behaviors. Methods Data were collected at baseline from girls participating in a school-based intervention to prevent weight-related problems. Participants included 365 adolescent girls from 12 high schools. The girls’ mean age was 15.8 years; 46% were overweight or obese; and over 75% were racial/ethnic minorities. Results A high percentage of girls reported parent weight talk (i.e., comments about one’s own weight and encouragement of daughter to diet), parent dieting, and family weight-teasing. For example, 45% of the girls reported that their mothers encouraged them to diet and 58% reported weight-teasing by family members. Weight-teasing was strongly associated with higher BMI, body dissatisfaction, unhealthy and extreme weight control behaviors, and binge eating with loss of control in the girls. Parent weight talk, particularly by mothers, was associated with a number of disordered eating behaviors. Mother dieting was associated with girls’ unhealthy and extreme weight control behaviors. In no instances were family weight talk and dieting variables associated with better outcomes in the girls. Conclusions Parent weight-related comments and dieting behaviors, and family weight-teasing, may contribute to disordered eating behaviors in adolescent girls. Health care providers can help parents provide a supportive home environment by discouraging weight-based comments, which may be intended to be helpful, but can have unintentional harmful consequences.

    Latina women are vulnerable to poor body image, eating disorders, and obesity, particularly during the college years. This study sought to identify common cultural antecedents of these concerns in order to inform the development of prevention programs for this population. Six groups of university students who identified as Latina (N=27) discussed cultural aspects of body image, eating disorders, and obesity. Thematic analysis identified four main themes: (a) cultural disparities in body-ideal, including the influence of the media and acculturation issues; (b) messages about body shape and weight received by family, peers, and society; (c) difficulties making healthy eating and physical activity choices as a function of college life; and (d) the influence of peers and potential male partners on body satisfaction and body-ideals. These results have implications for the development of programs targeting body dissatisfaction and risk for eating disorders and obesity in Latina college women. PMID:22609033

    Objective This population-based study examined mothers’ weight-related concerns and behaviors (weight status, weight dissatisfaction, dieting, and encouraging child to diet) at baseline, as assessed by both mothers and adolescents, and associations with adolescents’ body dissatisfaction and weight control practices 5 years later. Methods Adolescents and their mothers (n = 443 pairs) were surveyed in 1998–1999; adolescents were resurveyed in 2003–2004. Results Baseline maternal report of higher levels of her weight-related concerns/behaviors was associated with greater body dissatisfaction in girls 5 years later, controlling for adolescent weight status and other covariates. Baseline maternal report of weight-related concerns/behaviors was also associated with greater prevalence of trying to lose weight in both boys and girls 5 years later. Baseline adolescent report of higher maternal weight-related concerns/behaviors was associated with a higher prevalence of trying to lose weight 5 years later in girls. Conclusions These findings highlight the importance of mothers’ weight-related concerns and behaviors for adolescents’ weight-related outcomes.

    2014-11-01

    Women with attachment insecurity have greater eating disorder symptoms and poorer prognosis. Socio-cultural agents, such as peers and family, are predictive of the development of body image dissatisfaction (BID). The present study examines the association of insecure attachment styles and direct and indirect social comparisons of body image to women's BID and drive to thinness. Two hundred and eighty three women aged 18-42 years completed online self-reports concerning attachment styles, body mass index (BMI), drive for thinness, body image satisfaction, the Figure Rating Scale (FRS), as well as a modified FRS comparing self to mother, to sister closest in age and to best friend. Hierarchical Linear Models reveal that anxious-ambivalent, but not avoidant attachment style, along with indirect and direct comparisons to best friend and to sister influence drive for thinness and body dissatisfaction, even after controlling for BMI and age. Of all social comparisons, feeling one's best friend is thinner than yourself is the most detrimental to body ideal. PMID:25257536

    Sixty-eight percent of U.S. adults are overweight/obese, and this epidemic has physical, psychosocial, and behavioral consequences. An internet sample of adults (N=2997) perceiving themselves as larger than ideal in clothing size reported their body mass index (BMI), relative clothing size (RS; discrepancy between current and ideal size), and avoidance behaviors. Exploratory factor analysis of 10 avoidance items produced social avoidance and body display avoidance factors. A relative importance analysis revealed RS as a better predictor than BMI for avoidance. A hierarchical multivariate analysis of covariance found RS to predict both avoidance constructs. The relationship between RS and both avoidance constructs was stronger for women than men, and for younger as compared to older participants. Caucasians reported more body display avoidance than African Americans. This suggests that personal dissatisfaction with body size may deter involvement in varied life events and that women are especially avoidant of activities that entail displaying their bodies.

    2015-06-01

    Although self-harm has been observed among patients with eating disorders, the effects of such tendencies on treatment outcomes are unclear. The current study employed structural equation modeling to (a) evaluate the relationship between self-harm and changes in body dissatisfaction and drive for thinness in a large sample of patients (n = 2061) who underwent inpatient treatment, and (b) to examine whether the relationship between self-harm and changes in body dissatisfaction and drive for thinness during inpatient treatment remains significant when controlling for change in negative affect during treatment. Results revealed that patients with a history of self-harm reported significantly less reduction in body dissatisfaction and drive for thinness following treatment. Patients experiencing less change in negative affect also reported significantly less reduction in body dissatisfaction and drive for thinness after discharge from treatment. However, the association between history of self-harm and reduction in body dissatisfaction and drive for thinness after treatment became non-significant when controlling for change in negative affect. This pattern of findings was also replicated among patients with a primary diagnosis of anorexia nervosa (n = 845), bulimia nervosa (n = 565), and eating disorder not otherwise specified (n = 651). The implications of these findings for delineating the specific role of self-harm in the nature and treatment of eating disorders are discussed. PMID:25868550

    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

Media influence and body image in 8-11-year-old boys and girls: A preliminary report on the multidimensional media influence scale. International Journal of Eating Disorders, 29, 37-44) is a child-appropriate, 3-factor scale designed to assess perceived media influence on body image. It has been used in studies exploring the relationship between the entire scale as well as its subscales (awareness, internalization, and pressure) and variables related to body image. However, the 3-factor structure of the scale has never been confirmed via confirmatory factor analysis (CFA), nor has the scale been evaluated with a racially diverse sample of children. This paper reports the results of CFAs establishing the multidimensionality of the scale and the unidimensionality of its subscales among a sample of 661 girls and boys aged 7-12 years, primarily African American and Anglo American. The pressure factor of the MMIS predicted the idealization of a thinner current (child) and future (adult) body both cross-sectionally and one year later for girls and for Anglo American children.

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

  10. Age, puberty, body dissatisfaction, and physical activity decline in adolescents. Results of the German Health Interview and Examination Survey (KiGGS)

    PubMed Central

    2011-01-01

    Background Physical activity (PA) shows a marked decline during adolescence. Some studies have pointed to pubertal status or timing as possible PA determinants in this age group. Furthermore, it was supposed that the impact of pubertal changes on PA might be mediated by psychological variables like body dissatisfaction (BDS). Methods The 11- to 17-year-old subsample of the German Health Interview and Examination Survey (KiGGS) was used (n = 6 813; 51.3% male, response rate = 66.6%). Through sex-specific sequential multinomial logistic regressions we analysed the univariate and independent associations of chronological age, absolute pubertal status, relative pubertal timing, and BDS with the frequency of PA. Results Chronological age showed a significantly negative association with PA in both sexes, independent of puberty. The odds of inactivity in contrast to nearly daily PA increased about 70% in boys and 35% in girls for each year of age, respectively. Adjusted for age and other possible confounders, inactivity was significantly less likely for boys in late pubertal stages (OR = 0.27, 95% CI = 0.09-0.78). The risk of inactivity was more than doubled in boys maturing earlier than peers in terms of relative pubertal timing (OR = 2.20, 95% CI = 1.36-3.56). No clear significant puberty effects were found in girls, but the inactivity was more likely for those with irregular menstruation (OR = 1.71, 95% CI = 1.06-2.75). BDS also contributed to the prediction of PA in both sexes. It partially mediated puberty effects in boys but not in girls. Conclusions Overall, chronological age was a far more important predictor of PA in German adolescents than absolute pubertal status or relative pubertal timing. Further possible explanatory variables like sociocultural influences, social support or increasing time requirements for education should be analysed in conjunction with chronological age in future studies.

    2012-01-01

    The majority of body image research has studied younger women and girls, ignoring older age groups. Therefore, the purpose of this study was to explore body image among retirement-age women. The sample included 13 women aged 60 to 69. Data collection occurred in two phases. Participants completed individual in-depth interviews and attended follow-up focus groups. Transcripts from both phases of data collection were analyzed thematically using the constant comparison method. Themes emerged regarding the participants' definitions of body image, their attitudes about appearance, and their current perceptions of their bodies. Findings highlighted the complexity of older women's body image as characterized by the dual existence of contentment and desire for physical change. Participants offered explanations for this seeming contradiction, including consideration of age, prioritization of preferred aspects of the body or the self, and focus on aspects of appearance that are perceived to be within the individual's control.

    Backround Appearance concerns are of increasing importance in young men's lives. We investigated whether muscle dissatisfaction is associated with psychological symptoms, dietary supplement or anabolic steroid use, or physical activity in young men. Methods As a part of a questionnaire assessment of health-related behaviors in the population-based FinnTwin16 study, we assessed factors associated with muscle dissatisfaction in 1245 men aged 22–27 using logistic regression models. Results Of men, 30% experienced high muscle dissatisfaction, while 12% used supplements/steroids. Of highly muscle-dissatisfied men, 21.5% used supplements/steroids. Mean body mass index, waist circumference, or leisure aerobic activity index did not differ between individuals with high/low muscle dissatisfaction. Muscle dissatisfaction was significantly associated with a psychological and psychosomatic problems, alcohol and drug use, lower height satisfaction, sedentary lifestyle, poor subjective physical fitness, and lower life satisfaction. Conclusion Muscle dissatisfaction and supplement/steroid use are relatively common, and are associated with psychological distress and markers of sedentary lifestyle. PMID:16594989

    2011-09-01

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

    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.

    2016-06-01

    The current study aimed to investigate the effect of digital alteration disclaimer labels appended to fashion magazine advertisements, as well as instructional condition, on women's social comparison and body dissatisfaction. Participants were 378 female undergraduate students who viewed 11 thin ideal advertisements with either no disclaimer, a generic disclaimer, or a more detailed specific disclaimer. There were three instructional conditions: neutral, distractor, and social comparison. Disclaimer labels did not affect appearance comparison or body dissatisfaction, but instructional condition did, with the social comparison instructions producing the highest appearance comparison and body dissatisfaction. In addition, there was a three-way interaction with trait appearance comparison, such that women high on trait appearance comparison who saw specifically worded disclaimers in the distractor instructional condition experienced increased body dissatisfaction, whereas women low on this trait experienced decreased body dissatisfaction. It seems that both instructions and individual differences may influence responses to disclaimer labels. PMID:27061258

    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.

    2014-09-01

    Fat talk is a style of verbal expression among young women involving negative self-statements, complaints about physical appearance, and weight management. This research used ecological momentary assessment to examine the impact of naturalistic fat talk experiences on body dissatisfaction, body checking, negative affect, and disordered eating behaviors. We examined trait self-objectification as a moderator. Sixty-five female college students completed a baseline questionnaire and responded to questions when randomly prompted by palm pilot devices for five days. Results indicated fat talk is common and associated with greater body dissatisfaction, body checking, negative affect, and disordered eating behaviors. Fat talk participation was associated with greater body checking than overhearing fat talk. Greater trait self-objectification was associated with greater body dissatisfaction and body checking following fat talk. These results suggest that fat talk negatively impacts the cognitions, affect, and behavior of young women and has increased negative effects for women higher in self-objectification. PMID:24976570

    We use data from the European Community Household Panel to investigate the impact of body weight on wages in nine European countries. When we pool the available data across countries and years, we find that a 10% increase in the average body mass index reduces the real earnings of males and females by 3.27% and 1.86%, respectively. Since European culture, society and labour market are heterogeneous, we estimate separate regressions for Northern and Southern Europe and find that the negative impact of the body mass index on earnings is larger--and statistically significant--in the latter area.

    2003-07-01

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

    Body composition and body mass are pivotal clinical endpoints in studies of welfare diseases. We present a combined effort of established and new mathematical models based on rigorous monitoring of energy intake (EI) and body mass in mice. Specifically, we parameterize a mechanistic turnover model based on the law of energy conservation coupled to a drug mechanism model. Key model variables are fat-free mass (FFM) and fat mass (FM), governed by EI and energy expenditure (EE). An empirical Forbes curve relating FFM to FM was derived experimentally for female C57BL/6 mice. The Forbes curve differs from a previously reported curve for male C57BL/6 mice, and we thoroughly analyse how the choice of Forbes curve impacts model predictions. The drug mechanism function acts on EI or EE, or both. Drug mechanism parameters (two to three parameters) and system parameters (up to six free parameters) could be estimated with good precision (coefficients of variation typically <20 % and not greater than 40 % in our analyses). Model simulations were done to predict the EE and FM change at different drug provocations in mice. In addition, we simulated body mass and FM changes at different drug provocations using a similar model for man. Surprisingly, model simulations indicate that an increase in EI (e.g. 10 %) was more efficient than an equal lowering of EI. Also, the relative change in body mass and FM is greater in man than in mouse at the same relative change in either EI or EE. We acknowledge that this assumes the same drug mechanism impact across the two species. A set of recommendations regarding the Forbes curve, vehicle control groups, dual action on EI and loss, and translational aspects are discussed. This quantitative approach significantly improves data interpretation, disease system understanding, safety assessment and translation across species. PMID:24158456

    2014-06-01

    Criminals have been known to dispose of bodies in zipped suitcases in an attempt to conceal murder. In order to investigate the forensic implications of this mode of disposal on calculating time of death, it is necessary to study the accessibility of bodies in suitcases to blowflies (Diptera: Calliphoridae) and the possibility of oviposition and infestation under these circumstances. An experimental apparatus was designed that incorporated different zips (toothed and coil) of various gauges (4-6 mm) above a chicken liver bait. Gravid Calliphora vomitoria and Calliphora vicina females were attracted to and oviposited on and through these zips, both under laboratory and field conditions. Egg laying was significantly more frequent and with greater numbers of eggs when zips were in contact with the bait than when they were placed approximately 6cm above the bait. In the absence of bait, adult females could be stimulated to lay eggs on moistened zips, although the presence of blood accelerated egg laying compared to water alone. No eggs were laid on dry zips in the absence of bait. Of the first instar larvae tested, 89% were able to colonise the bait below the zips by passing through gaps between the teeth. Preliminary field studies using suitcases baited with a pig's head indicated that there was a delay of 1-3 days in oviposition when compared to laboratory conditions. This information has practical value in explaining the presence of larvae on enclosed bodies in suitcases and will help forensic entomologists estimate a more accurate minimum time since death.

    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.

    2016-05-01

    This study attempts to re-examine the role of attitude in voluntary information system (IS) acceptance and usage, which has often been discounted in the previous technology acceptance research. We extend the unidimensional view of attitude into a bidimensional one, because of the simultaneous existence of both positive and negative evaluation towards IS in technology acceptance behaviour. In doing so, attitude construct is divided into two components: satisfaction as the positive attitudinal component and dissatisfaction as the negative attitudinal component. We argue that satisfaction and dissatisfaction will interactively affect technology usage intention. Besides, we explore the predictors of satisfaction and dissatisfaction based on the disconfirmation theory. Empirical results from a longitudinal study on bulletin board system (BBS) usage confirm the interaction effect of satisfaction and dissatisfaction on usage intention. Moreover, perceived task-related value has a significant effect on satisfaction, while perceived personal value has a significant effect on dissatisfaction. We also discuss the theoretical and managerial implications of our findings.

  17. Body size affects the evolution of eyespots in caterpillars

    2015-01-01

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

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

    PubMed

    Marshall, George Robert Ellison; Hooker, Claire

    2016-06-01

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

  20. 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.

    During the last century the patient-doctor relationship has changed considerably. This change becomes particularly visible when the relationship between the two parties is disturbed. this is usually caused by patient dissatisfaction with the doctor or other workers in the medical profession. Handling dissatisfaction should be part of a doctor's professional skills. The most important advice in dealing with dissatisfaction is to react fast. A doctor should have the good sense to raise the issue for discussion as soon as he/she senses signs of dissatisfaction. If this is not possible and the issue results in a written complaint, the plaintiff can lodge a complaint within the framework of a special law. The complaint is then handled by a complaints committee. Over the past years, mediation has been used increasingly. This procedure has a low threshold, works fast and often results in reconciliation of both parties. If the intervention of a complaints committee is not desired and mediation is not realistic or rejected, the case sometimes progresses to the disciplinary board or civil judge. This often leads to protracted procedures and is stressful to both parties. It is important to prevent these kinds of procedures as much as possible by reacting swiftly and appropriately to signs of dissatisfaction. PMID:12448961

    Through an employee survey administered at Kaweah Delta Health Care District (KDHCD) in Visalia, Calif., several sources of dissatisfaction were noted, including communication, equipment, staffing and rapid growth. Perceiving no real movement toward resolving these issues, employees vented their frustrations to administration. As director of imaging services, I enlisted the help of two inside consultants, KDHCD's director of education and the director of the Employee Assistance Program (EAP). We initiated a process that is ongoing, to move the department toward working together as a team to solve problems within their control. We three directors decided to work with a leadership group to: assess the history of the department clarify the current reality create a vision of the future learn the Covey Habit 4, "Think Win-Win" capture agreements that lead staff and managers to work in self-motivated, self-directed work teams have the director of education present the work to the staff at large, and encourage the leadership team to continue to learn tools that would help the group to improve. The two inside consultants held a series of training meetings with the leadership group of 15, which included a staff member from each modality, site and support service. Participation was optional, and all who were asked agreed to participate. The meetings were held weekly for four weeks for two hours before regular work hours. At the conclusion of the training, the group agreed to continue to meet weekly. After the first four meetings, a summary of the training was presented at a meeting of the full imaging staff plus the vice president of professional services at KDHCD. Through this program, imaging services staff members at KDHCD have achieved an increased sense of cohesion in the group, learned that we have control over some things and not others, and are learning to hold each other accountable with kindness. We are giving each other the benefit of the doubt. We have not

    Patient satisfaction is a focal concern of health-care delivery and an expected outcome of medical care. Recently, the violent conflict between doctors and patients in China has intensified. Patient dissatisfaction has been recognized as an important concern and an urgent issue in the reform of China's health care. The objectives of this study are to investigate the determinants of patient dissatisfaction attributed to patient, hospital, and health-care market characteristics, as well as to explore the major determinants in the context of China. Data from 2007 to 2010 Urban Resident Basic Medical Insurance Survey (URBMIS) are used in this study. A total of 13,336 patients are selected conditional on health-care utilization. Analysis of satisfaction is based on outpatient utilization (last 2 weeks' reference, 6393 individuals) and inpatient utilization (last 1-year reference, 6943 individuals). Satisfaction was measured as ordinal variables (scales 1-5). Ordinary least squares (OLS) regression and an ordered probit model are applied to investigate the determinants. Blinder-Oaxaca decomposition is further employed to detect the proportion each predictor's contribution. The results indicate that patients' gender, education, and insurance status are significantly related to patient satisfaction. Higher-level hospitals are found to negatively correlate with patient satisfaction. Lower competition in providers' market and a higher market share of private hospitals are found to positively correlate with patient dissatisfaction. Meanwhile, the survey indicates that "medical charges too expensive" is chiefly responsible for patient dissatisfaction. Our study provides empirical evidence on the determinants of patient dissatisfaction in China. In particular, the results indicate that establishing a high competition among various providers in the health-care market will act as a "double-edged sword," with great policy implications.

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

    Body 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.

    2016-08-01

    The present study shows how motor expertise increases individuals' sensitivity to others' affective body movement. This enhanced sensitivity is evident in the experts' behavior and physiology. Nineteen affective movement experts (professional ballet dancers) and 24 controls watched 96 video clips of emotionally expressive body movements while they performed an affect rating task (subjective response), and their galvanic skin response was recorded (physiological response). The movements in the clips were either sad or happy, and in half of the trials, movements were played in the order in which they are learned (forward presentation), and in the other half, movements were played backward (control condition). Results showed that motor expertise in affective body movement specifically modulated both behavioral and physiological sensitivity to others' affective body movement, and that this sensitivity is particularly strong when movements are shown in the way they are learnt (forward presentation). The evidence is discussed within current theories of proprioceptive arousal feedback and motor simulation accounts. (PsycINFO Database Record PMID:26882181

    Fat talk is not merely correlated with, but appears to be one of the causes of body dissatisfaction in other women. Moderators of fat talk's deleterious effects, however, have not yet been identified. This experiment tested whether the body type of the fat-talker affects listeners' body satisfaction. Women viewed photos of either noticeably thin or overweight women making either fat talk or positive body statements. Fat talk by thin and overweight women both had a negative impact on women's body satisfaction, but dissatisfaction was highest after exposure to photos of thin women making fat talk statements. Statistically indistinguishable from this latter effect, however, was the negative effect of thin women making positive body statements. Results are considered within a social comparison framework. Theoretical implications for the thin-ideal and fat talk literatures are presented, as are clinical implications for work with clients. PMID:24320716

  18. Sneaker Males Affect Fighter Male Body Size and Sexual Size Dimorphism in Salmon.

    PubMed

    Weir, Laura K; Kindsvater, Holly K; Young, Kyle A; Reynolds, John D

    2016-08-01

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

  19. Environmental Factors Affecting Large-Bodied Coral Reef Fish Assemblages in the Mariana Archipelago

    2012-01-01

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

    This study examines (1) whether there are employment grade and gender differences in job dissatisfaction and (2) whether work, family, and personality characteristics explain grade and gender differences in job dissatisfaction. The participants were 3,812 civil servants, aged 20-65, working at a local government in Japan. In both males and females, low control, low social support, work-to-family conflict, type A behaviour pattern and negative affectivity were significantly associated with job dissatisfaction. In females, high demands, long work hours and being unmarried were also associated with job dissatisfaction. Among males, in comparison with the highest grade employees, the age-adjusted odds ratio (OR) for job dissatisfaction in the lowest grade employees was 1.90 (95% CI: 1.40-2.59). The grade differences reduced to 1.08 (0.76-1.54) after adjustment for work, family and personality characteristics. Among females, similar grade differences were observed, although the differences were not statistically significant. In comparison with males, the age-adjusted OR in females for job dissatisfaction was 1.32 (1.14-1.52). This gender difference was reduced to 0.95 (0.79-1.14) following adjustment for the other factors. The majority of employees belong to low to middle grades, and female employees have increased. Reducing grade and gender differences in work and family characteristics is needed. PMID:25055848

  1. Mussel fishery affects diet and reduces body condition of Eiders Somateria mollissima in the Wadden Sea

    NASA Astrophysics Data System (ADS)

    2009-06-01

    Although the Danish Wadden Sea is of international importance for several bird species, large-scale blue mussel Mytilus edulis fishing took place from 1984-1987, ceasing thereafter due to low mussel stocks. Mussel fishing removes much of the blue mussel biomass, especially larger individuals. Hence we predict that intensive mussel fishing will affect their predators, such as the Eider Somateria mollissima, which is predominantly a blue mussel feeder by, 1) reducing the amount of blue mussels in their diet relative to alternative prey items, 2) exploitation of smaller blue mussel shell classes, 3) loss of body condition, 4) changing feeding distribution to aggregate to the remaining mussel stocks, and 5) decreasing numbers. Before winter 1986/87 blue mussel biomass was estimated at 40,600 tons, decreasing to 15,400 tons in 1987/88 due to mussel fishery. We collected Eiders in both periods to monitor their diet and body mass and used aerial surveys to determine changes in numbers and distribution. Between the two periods, blue mussels declined in the Eiders diet, numbers of Eiders with empty stomachs increased and the mean length of blue mussel taken by Eiders decreased. Eider body condition declined from 1986/87 to 1987/88, mostly the result of the reduction in numbers of individuals with blue mussel remains in their gizzards and in better body condition compared to those taking alternative food items or having empty gizzards. Eiders shifted their distribution from the southern part of the Danish Wadden Sea to the northern part, where the remaining blue mussel stocks were situated. Eider numbers were lowest in 1987/88, the year of lowest blue mussel stocks. We conclude that intensive mussel fishery affected the Eider's diet, reduced their body condition and affected distribution and abundance. The results also showed that availability of blue mussels may have a key role in building up and maintaining body condition in Eiders during winter.

    2004-01-01

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

    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. PMID:21664886

  5. Does winter region affect spring arrival time and body mass of king eiders in northern Alaska?

    Powell, Abby N.; Oppel, Steffen

    2009-01-01

    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.

  6. Disturbance of Intentionality: A Phenomenological Study of Body-Affecting First-Rank Symptoms in Schizophrenia

    PubMed Central

    Thomann, Philipp Arthur; Fuchs, Thomas

    2013-01-01

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

    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.

    The aim of the current study was to add to the growing body of research on men with eating disorders by examining the association between different types of body dissatisfaction (muscularity and body fat) and disordered eating in heterosexual and gay men. Two hundred four participants (over one-third were gay) completed measures assessing disordered eating, muscularity and body fat dissatisfaction, and sexual orientation. Body fat dissatisfaction, but not muscularity dissatisfaction, predicted disordered eating, dietary restraint, and concerns about weight and eating in gay and heterosexual men. These findings were consistent across all measures of body fat and muscularity dissatisfaction, providing stronger evidence that body fat dissatisfaction may be a greater risk factor for disordered eating in both gay and heterosexual college aged men than muscularity dissatisfaction.

  17. 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

    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.

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

  1. Factors contributing to discomfort or dissatisfaction as a result of wearing personal protective equipment.

    1998-12-01

    In a metal refining plant, 366 workers were interviewed to investigate factors contributing to the discomfort or dissatisfaction of wearing personal protective equipment (PPE). Up to 97.8% of these individuals used one or more types of PPE. The percentages of employees who reported their hard hats and cooling vests as comfortable were 17% and 19%, respectively. Twenty-five percent of workers felt their respirators and safety harnesses were comfortable. Safety glasses ranked at 50%, gloves 53%, and safety shoes 54% for comfort factor. The percentage of employees who tolerated their PPE (just acceptable) ranged from 27% to 52%. The most frequently cited factors contributing to discomfort or dissatisfaction of wearing PPE were related to the workers' beliefs that the PPE was not needed, created a new hazard, interfered with work, was too heavy, was hard to wear, prohibited breathing or communicating, irritated skin, put pressure on the body, and was of an undesirable type or model.

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

    Gravimetric analysis and dual energy x-ray absorptiometry densitometry were used to determine lean, fat, and bone tissue traits in a F2 mouse population from a C57BL/6J and CASA/Rk intercross (B6CASAF2). These traits were used in a linkage analysis to identify quantitative trait loci that affect body composition. Linkage mapping showed that body weight (BW) loci on proximal chromosome 2 occurred in the same region as body length, lean tissue mass, and bone mineral content and on chromosome 13 in the same region as lean tissue mass, bone mineral density, and bone mineral content. Fat-related loci occurring on mid-chromosome 2 near 60 cM, proximal chromosome 6, and mid-chromosome 10 were distinct from BW, lean tissue, and bone tissue loci. In B6CASAF2 females, heterozygotes and CASA/Rk homozygotes at the chromosome 6 locus marker had higher body fat percentages, and this locus was responsible for 11% of the variance for body fat percentage. Female heterozygotes and C57BL/6J homozygotes at the chromosome 15 locus marker had higher bone mineral densities, and this locus could explain 8% of that trait's variance. A survey of the literature did not reveal any previous reports of fat-specific loci in the chromosomal 10 region near 42 cM reported in this study. The results of this study indicate that BW and BMI have limited usefulness as phenotypes in linkage or association studies when used as obesity phenotypes. PMID:17179051

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

    Previous studies on psychosocial aspects of tattooing have not examined prospective changes in self- and body-related attitudes as a result of obtaining a tattoo. In the present study, 82 British residents obtaining their first tattoo completed measures of state appearance anxiety and dissatisfaction prior to, and immediately after, obtaining a tattoo. They also completed measures of trait body appreciation, distinctive appearance investment, self-ascribed uniqueness, social physique anxiety, and self-esteem before obtaining a tattoo and three weeks later. Results showed that both women and men had significantly lower appearance anxiety and dissatisfaction immediately after obtaining their tattoo, and significantly higher body appreciation, distinctive appearance investment, self-ascribed uniqueness, and self-esteem after three weeks. Women reported greater social physique anxiety after three weeks, whereas men reported lower anxiety. These results are discussed in relation to the positive impacts of obtaining body art and the mainstreaming of tattooing in Western societies. PMID:21641893

    Human postural control is dependent on the central integration of vestibular, visual and proprioceptive inputs. Psychological states can affect balance control: anxiety, in particular, has been shown to influence balance mediated by visual stimuli. We hypothesized that patients with eating disorders would show postural destabilization when exposed to their image in a mirror and to the image of a fashion model representing their body ideal in comparison to body neutral stimuli. Seventeen females patients attending a day centre for the treatment of eating disorders were administered psychometric measures of body dissatisfaction, anxiety, depression and underwent posturographic measures with their eyes closed, open, watching a neutral stimulus, while exposed to a full length mirror and to an image of a fashion model corresponding to their body image. Results were compared to those obtained by eighteen healthy subjects. Eating disordered patients showed higher levels of body dissatisfaction and higher postural destabilization than controls, but this was limited to the conditions in which they were exposed to their mirror image or a fashion model image. Postural destabilization under these conditions correlated with measures of body dissatisfaction. In eating disordered patients, body related stimuli seem to act as phobic stimuli in the posturographic paradigm used. If confirmed, this has the potential to be developed for diagnostic and therapeutic purposes. PMID:27397012

    Relationships with children are important for parents' psychological well-being, yet limited research addresses whether and how relationships with adult children matter for aging parents' psychological well-being in mid- to later life. We used four waves of national longitudinal data (Americans' Changing Lives, N = 1,692) and growth curve models to test how multiple dimensions of the intergenerational relationship-social support, strain, equity, and dissatisfaction-shape mid- to later life parents' psychological distress over time. Results showed that social support and strain were associated with parents' distress at baseline but not over time, while relationship equity and dissatisfaction affected change in parents' psychological distress over time. Findings further showed how the effects of dissatisfaction varied for mothers and fathers. This study adds to an understanding of the social context of aging by drawing attention to how specific dimensions of the parent-child tie matter longitudinally for mid- to later life parents' psychological distress.

    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. ??

    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

    Pro-anorexia websites portray an extreme form of thin-ideal. This between-subjects experiment examined the effects of viewing such a website on body satisfaction, affect, and appearance self-efficacy compared to viewing control websites (fashion, home decoration, automutilation). The sample consisted of 124 normal weight, young adult, Dutch women (mean age 21.2, mean body mass index 21.4). Participants did not differ on affect and appearance self-efficacy. One body satisfaction measure showed that pro-anorexia viewers were more satisfied with their bodies than home decoration viewers. Our findings suggest that viewing a pro-anorexia website might not have detrimental effects on body satisfaction and affect among normal weight young women. PMID:24689982

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

    NASA Astrophysics Data System (ADS)

    2010-09-01

    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.

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

    NASA Astrophysics Data System (ADS)

    Haghighi, Erfan; Or, Dani

    2015-11-01

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

    2010-11-01

    The effect of fat accumulation on the prediction of in vivo body composition by a total body electrical conductivity (TOBEC) technique was evaluated using Japanese quail at 2 life periods (0 to 21 d and 28 to 70 d of age) that differ significantly in the fatness of birds. In total, 119 quail of 14 age categories were weighed and scanned by the TOBEC analyzer, and their carcasses were subjected to chemical analysis. The prediction equations for chemical composition (percentage of water, lipids, and lean tissue) and body masses (weight of body, water, lipids, and lean tissue) were obtained by linear regression analysis. The equations involved the E-value as the independent variable. In both growth phases, a high accuracy of estimation was found for the total body, lean, and water masses (0.85 ≤ R(2) ≤ 0.98), whereas a low accuracy of estimation was observed for percentages of lipids, lean tissue, and water (0.27 ≤ R(2) ≤ 0.64). Most of the variables showed a worse estimation in the late than in the early growth phase; the maximum difference was observed for the lipid mass (R(2) = 0.35 vs. 0.90, respectively). The correlations between analyzed variables and the residual error distributions of regression models demonstrated that the lower power of the models in the late versus early growth phase may be attributed to an enhanced fat accumulation in sexually mature birds. Their high fat reserves considerably decrease body hydration, which negatively influences the estimation of body composition based upon the TOBEC procedure. PMID:20952716

    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

    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.

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

    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. PMID:12445589

    The aim of the current study was to assess the relative uniqueness of three components of male body image (i.e., muscle, body fat, and height dissatisfaction) in the prediction of indices of psychological distress (i.e., depression, eating restraint, eating concerns, and social sensitivity) among a community sample of 228 gay men. Results indicated that body fat dissatisfaction was predictive of all four criterion variables (controlling for muscle dissatisfaction). Conversely, muscle dissatisfaction was only associated with social sensitivity, while height dissatisfaction failed to significantly predict any of the criterion variables. These findings highlight the relative importance of body fat dissatisfaction among gay men and suggest that researchers and clinicians working with this population should utilize measures which include assessment of both muscularity and body fat.

    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.

    Abstract In North America, there are few representative data about the effects of management practices on equine welfare. In a randomized survey of 312 nonracing horses in Prince Edward Island (response rate 68.4%), owners completed a pretested questionnaire and a veterinarian examined each horse. Regression analyses identified factors affecting 2 welfare markers: body condition score (BCS) and stereotypic behavior. Horses’ BCSs were high (mean 5.7, on a 9-point scale) and were associated with sex (males had lower BCSs than females; P < 0.001) and examination date (P = 0.052). Prevalences of crib biting, wind sucking, and weaving were 3.8%, 3.8%, and 4.8%, respectively. Age (OR = 1.07, P = 0.08) and hours worked weekly (OR = 1.12, P = 0.03) were risk factors for weaving. Straw bedding (OR = 0.3, P = 0.03), daily hours at pasture (OR = 0.94, P = 0.02), and horse type (drafts and miniatures had a lower risk than light horses; P = 0.12) reduced the risk of horses showing oral stereotypies. Some of these results contradict those of other studies perhaps because of populations concerned. PMID:16579039

    Dietary isoflavones, a group of secondary plant compounds that exhibit phytoestrogenic properties, are primarily found in soy. Prunetin, a representative isoflavone, was recently found to affect cell signaling in cultured cells; however, in vivo effects remain elusive. In this study, the model organism Drosophila melanogaster was used to investigate the effects of prunetin in vivo with respect to lifespan, locomotion, body composition, metabolism, and gut health. Adult flies were chronically administered a prunetin-supplemented diet. Prunetin improved median survival by 3 d, and climbing activity increased by 54% in males. In comparison with the females, male flies exhibited lower climbing activity, which was reversed by prunetin intake. Furthermore, prunetin-fed males exhibited increased expression of the longevity gene Sirtuin 1 (Sir2) (22%), as well as elevated AMPK activation (51%) and triglyceride levels (29%), whereas glucose levels decreased (36%). As females are long-lived compared with their male counterparts and exhibit higher triglyceride levels, prunetin apparently "feminizes" male flies via its estrogenicity. We conclude that the lifespan-prolonging effects of prunetin in the male fruit fly depend on changes in AMPK-regulated energy homeostasis via male "feminization." Collectively, we identified prunetin as a plant bioactive compound capable of improving health status and survival in male D. melanogaster. PMID:26538555

  7. Microtiming in Swing and Funk affects the body movement behavior of music expert listeners

    The theory of Participatory Discrepancies (or PDs) claims that minute temporal asynchronies (microtiming) in music performance are crucial for prompting bodily entrainment in listeners, which is a fundamental effect of the “groove” experience. Previous research has failed to find evidence to support this theory. The present study tested the influence of varying PD magnitudes on the beat-related body movement behavior of music listeners. 160 participants (79 music experts, 81 non-experts) listened to 12 music clips in either Funk or Swing style. These stimuli were based on two audio recordings (one in each style) of expert drum and bass duo performances. In one series of six clips, the PDs were downscaled from their originally performed magnitude to complete quantization in steps of 20%. In another series of six clips, the PDs were upscaled from their original magnitude to double magnitude in steps of 20%. The intensity of the listeners' beat-related head movement was measured using video-based motion capture technology and Fourier analysis. A mixed-design Four-Factor ANOVA showed that the PD manipulations had a significant effect on the expert listeners' entrainment behavior. The experts moved more when listening to stimuli with PDs that were downscaled by 60% compared to completely quantized stimuli. This finding offers partial support for PD theory: PDs of a certain magnitude do augment entrainment in listeners. But the effect was found to be small to moderately sized, and it affected music expert listeners only. PMID:26347694

  9. [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.

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. PMID:19703916

    The early visual event-related 'N170 response' is sensitive to human body configuration and it is enhanced to nude versus clothed bodies. We tested whether the N170 response as well as later EPN and P3/LPP responses to nude bodies reflect the effect of increased arousal elicited by these stimuli, or top-down allocation of object-based attention to the nude bodies. Participants saw pictures of clothed and nude bodies and faces. In each block, participants were asked to direct their attention towards stimuli from a specified target category while ignoring others. Object-based attention did not modulate the N170 amplitudes towards attended stimuli; instead N170 response was larger to nude bodies compared to stimuli from other categories. Top-down attention and affective arousal had additive effects on the EPN and P3/LPP responses reflecting later processing stages. We conclude that nude human bodies have a privileged status in the visual processing system due to the affective arousal they trigger. PMID:25224182

    2014-07-01

    Size perception is most often explained by a combination of cues derived from the visual system. However, this traditional cue approach neglects the role of the observer's body beyond mere visual comparison. In a previous study, we used a full-body illusion to show that objects appear larger and farther away when participants experience a small artificial body as their own and that objects appear smaller and closer when they assume ownership of a large artificial body ("Barbie-doll illusion"; van der Hoort, Guterstam, & Ehrsson, PLoS ONE, 6(5), e20195, 2011). The first aim of the present study was to test the hypothesis that this own-body-size effect is distinct from the role of the seen body as a direct familiar-size cue. To this end, we developed a novel setup that allowed for occlusion of the artificial body during the presentation of test objects. Our results demonstrate that the feeling of ownership of an artificial body can alter the perceived sizes of objects without the need for a visible body. Second, we demonstrate that fixation shifts do not contribute to the own-body-size effect. Third, we show that the effect exists in both peri-personal space and distant extra-personal space. Finally, through a meta-analysis, we demonstrate that the own-body-size effect is independent of and adds to the classical visual familiar-size cue effect. Our results suggest that, by changing body size, the entire spatial layout rescales and new objects are now perceived according to this rescaling, without the need to see the body. PMID:24806404

    Objectives Ti, which is biocompatible and resistant to corrosion, is widely used for dental implants, particularly in patients allergic to other materials. However, numerous studies have reported on Ti allergy and the in vitro corrosion of Ti. This study investigated the conditions that promote the elution of Ti ions from Ti implants. Methods Specimens of commercially pure Ti, pure nickel, a magnetic alloy, and a gold alloy were tested. Each specimen was immersed in a simulated body fluid (SBF) whose pH value was controlled (2.0, 3.0, 5.0, 7.4, and 9.0) using either hydrochloric or lactic acid. The parameters investigated were the following: duration of immersion, pH of the SBF, contact with a dissimilar metal, and mechanical stimulus. The amounts of Ti ions eluted were measured using a polarized Zeeman atomic absorption spectrophotometer. Results Eluted Ti ions were detected after 24 h (pH of 2.0 and 3.0) and after 48 h (pH of 9.0). However, even after 4 weeks, eluted Ti ions were not detected in SBF solutions with pH values of 5.0 and 7.4. Ti elution was affected by immersion time, pH, acid type, mechanical stimulus, and contact with a dissimilar metal. Elution of Ti ions in a Candida albicans culture medium was observed after 72 h. Significance Elution of Ti ions in the SBF was influenced by its pH and by crevice corrosion. The results of this study elucidate the conditions that lead to the elution of Ti ions in humans, which results in implant corrosion and Ti allergy. PMID:23762461

    The endoplasmic reticulum (ER) bodies are ER-derived structures that are found in Brassicaceae species and thought to play a role in defense. Here, we have investigated the occurrence, distribution and function of ER bodies in root cells of Raphanus sativus using a combination of microscopic and biochemical methods. We have also assessed the response of ER bodies to methyl jasmonate (MeJA), a phytohormone that mediates plant defense against wounding and pathogens. Our results show that (i) ER bodies do occur in different root cell types from the root cap region to the differentiation zone; (ii) they do accumulate a PYK10-like protein similar to the major marker protein of ER bodies that is involved in defense in Arabidopsis thaliana; and (iii) treatment of root cells with MeJA causes a significant increase in the number of ER bodies and the activity of β-glucosidases. More importantly, MeJA was found to induce the formation of very long ER bodies that results from the fusion of small ones, a phenomenon that has not been reported in any other study so far. These findings demonstrate that MeJA impacts the number and morphology of functional ER bodies and stimulates ER body enzyme activities, probably to participate in defense responses of radish root. They also suggest that these structures may provide a defensive system specific to root cells. PMID:25305245

  19. Features of objectified body consciousness and sociocultural perspectives as risk factors for disordered eating among late-adolescent women and men.

    2015-10-01

    Body surveillance and body shame are features of objectified body consciousness (OBC) that have been linked to disordered eating, yet the evidence base is largely cross-sectional and limited to samples in certain Western countries. Furthermore, it is not clear whether these factors contribute to the prediction of eating disturbances independent of conceptually related risk factors emphasized within other sociocultural accounts. In this prospective study, body surveillance, body shame, and features of complementary sociocultural models (i.e., perceived appearance pressure from mass media and close interpersonal networks, appearance social comparisons, negative affect, body dissatisfaction) were assessed as risk factors for and concomitants of eating disturbances over time. University-age, mainland Chinese women (n = 2144) and men (n = 1017) completed validated measures of eating-disorder pathology and hypothesized risk factors at baseline (T1) and 1-year follow-up (T2). Among women, elevations on T1 measures of sociocultural-model features predicted more T2 eating disturbances, independent of T1 disturbances. After controlling for other T1 predictors, body surveillance and shame made modest unique contributions to the model. Finally, heightened T2 body dissatisfaction, media, and interpersonal appearance pressure, negative affect, and body shame predicted concomitant increases in T2 eating concerns. For men, T1 features of sociocultural accounts (negative affect, body dissatisfaction) but not OBC predicted T2 eating disturbances, along with attendant elevations in T2 negative affect, interpersonal appearance pressure, and body shame. Implications are discussed for theory and intervention that target disordered eating. PMID:26191981

    Body height and other body attributes of humans may be associated with a diverse range of social outcomes such as attractiveness to potential mates. Despite evidence that each parameter plays a role in mate choice, we have little understanding of the relative role of each, and relationships between indices of physical appearance and general health. In this study we tested relationships between immune function and body height of young men and women. In men, we report a non-linear relationship between antibody response to a hepatitis-B vaccine and body height, with a positive relationship up to a height of 185 cm, but an inverse relationship in taller men. We did not find any significant relationship between body height and immune function in women. Our results demonstrate the potential of vaccination research to reveal costly traits that govern evolution of mate choice in humans and the importance of trade-offs among these traits.

    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.

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

    PubMed Central

    2013-01-01

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

In this review article we point out three emerging streams of research highlighting the importance of vestibular input: (1) Spatial Cognition: Modulation of vestibular signals can induce specific changes in spatial cognitive tasks like mental imagery and the processing of numbers. This has been shown in studies manipulating body orientation (changing the input from the otoliths), body rotation (changing the input from the semicircular canals), in clinical findings with vestibular patients, and in studies carried out in microgravity. There is also an effect in the reverse direction; top-down processes can affect perception of vestibular stimuli. (2) Body Representation: Numerous studies demonstrate that vestibular stimulation changes the representation of body parts, and sensitivity to tactile input or pain. Thus, the vestibular system plays an integral role in multisensory coordination of body representation. (3) Affective Processes and Disorders: Studies in psychiatric patients and patients with a vestibular disorder report a high comorbidity of vestibular dysfunctions and psychiatric symptoms. Recent studies investigated the beneficial effect of vestibular stimulation on psychiatric disorders, and how vestibular input can change mood and affect. These three emerging streams of research in vestibular science are—at least in part—associated with different neuronal core mechanisms. Spatial transformations draw on parietal areas, body representation is associated with somatosensory areas, and affective processes involve insular and cingulate cortices, all of which receive vestibular input. Even though a wide range of different vestibular cortical projection areas has been ascertained, their functionality still is scarcely understood. PMID:24904327

    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

  9. Beyond the colour of my skin: how skin colour affects the sense of body-ownership.

    Multisensory stimulation has been shown to alter the sense of body-ownership. Given that perceived similarity between one's own body and those of others is crucial for social cognition, we investigated whether multisensory stimulation can lead participants to experience ownership over a hand of different skin colour. Results from two studies using introspective, behavioural and physiological methods show that, following synchronous visuotactile (VT) stimulation, participants can experience body-ownership over hands that seem to belong to a different racial group. Interestingly, a baseline measure of implicit racial bias did not predict whether participants would experience the RHI, but the overall strength of experienced body-ownership seemed to predict the participants' post-illusion implicit racial bias with those who experienced a stronger RHI showing a lower bias. These findings suggest that multisensory experiences can override strict ingroup/outgroup distinctions based on skin colour and point to a key role for sensory processing in social cognition.

  10. Early trauma and affect: the importance of the body for the development of the capacity to symbolize.

    PubMed

    Willemsen, Hessel

    2014-11-01

    In this paper I aim to outline the importance of working clinically with affect when treating severely traumatized patients who have a limited capacity to symbolize. These patients, who suffer the loss of maternal care early in life, require the analyst to be closely attuned to the patient's distress through use of the countertransference and with significantly less attention paid to the transference. It is questionable whether we can speak of transference when there is limited capacity to form internal representations. The analyst's relationship with the patient is not necessarily used to make interpretations but, instead, the analyst's reverie functions therapeutically to develop awareness and containment of affect, first in the analyst's mind and, later, in the patient's, so that, in time, a relationship between the patient's mind and the body, as the first object, is made. In contrast to general object-relations theories, in which the first object is considered to be the breast or the mother, Ferrari (2004) proposes that the body is the first object in the emerging mind. Once a relationship between mind and body is established, symbolization becomes possible following the formation of internal representations of affective states in the mind, where previously there were few. Using Ferrari's body-mind model, two clinical case vignettes underline the need to use the countertransference with patients who suffered chronic developmental trauma in early childhood.

    Factors such as temperature, habitat, larval density, food availability and food quality substantially affect organismal development. In addition, risk of predation has a complex impact on the behavioural and morphological life history responses of prey. Responses to predation risk seem to be mediated by physiological stress, which is an adaptation for maintaining homeostasis and improving survivorship during life-threatening situations. We tested whether predator exposure during the larval phase of development has any influence on body elemental composition, energy reserves, body size, climbing speed and survival ability of adult Drosophila melanogaster. Fruit fly larvae were exposed to predation by jumping spiders (Phidippus apacheanus), and the percentage of carbon (C) and nitrogen (N) content, extracted lipids, escape response and survival were measured from predator-exposed and control adult flies. The results revealed predation as an important determinant of adult phenotype formation and survival ability. D. melanogaster reared together with spiders had a higher concentration of body N (but equal body C), a lower body mass and lipid reserves, a higher climbing speed and improved adult survival ability. The results suggest that the potential of predators to affect the development and the adult phenotype of D. melanogaster is high enough to use predators as a more natural stimulus in laboratory experiments when testing, for example, fruit fly memory and learning ability, or when comparing natural populations living under different predation pressures.

    ABSTRACT Species that display seasonal variation in sickness intensity show the most intense response in the season during which they have the highest body mass, suggesting that sickness intensity may be limited by an animal's energy stores. Siberian hamsters (Phodopus sungorus) display lower body masses and less intense sickness when housed in short, winter-like days as opposed to long, summer-like days. To determine whether reduced sickness intensity displayed by short-day hamsters is a product of seasonal changes in body mass, we food restricted long-day hamsters so that they exhibited body mass loss that mimicked the natural photoperiod-induced loss of body mass in short-day hamsters. We then experimentally induced sickness with lipopolysaccharide (LPS) and compared sickness responses among long-day food-restricted and long- and short-day ad libitum fed groups, predicting that long-day food-restricted hamsters would show sickness responses comparable to those of short-day ad libitum fed hamsters and attenuated in comparison to long-day ad libitum fed hamsters. We found that long-day food-restricted hamsters showed attenuated LPS-induced anorexia, loss of body mass and hypothermia compared with long-day ad libitum fed animals; however, anorexia remained elevated in long-day food-restricted animals compared with short-day ad libitum fed animals. Additionally, LPS-induced anhedonia and decreases in nest building were not influenced by body mass. Results of hormone assays suggest that cortisol levels could play a role in the attenuation of sickness in long-day food-restricted hamsters, indicating that future research should target the roles of glucocorticoids and natural variation in energy stores in seasonal sickness variation.

    Extended work shifts of twelve hours or longer are common and even popular with hospital staff nurses, but little is known about how such extended hours affect the care that patients receive or the well-being of nurses. Survey data from nurses in four states showed that more than 80 percent of the nurses were satisfied with scheduling practices at their hospital. However, as the proportion of hospital nurses working shifts of more than thirteen hours increased, patients' dissatisfaction with care increased. Furthermore, nurses working shifts of ten hours or longer were up to two and a half times more likely than nurses working shorter shifts to experience burnout and job dissatisfaction and to intend to leave the job. Extended shifts undermine nurses' well-being, may result in expensive job turnover, and can negatively affect patient care. Policies regulating work hours for nurses, similar to those set for resident physicians, may be warranted. Nursing leaders should also encourage workplace cultures that respect nurses' days off and vacation time, promote nurses' prompt departure at the end of a shift, and allow nurses to refuse to work overtime without retribution.

    The aim of this study was to investigate the rate of relationship dissatisfaction among Australian women during the first year after childbirth and to uncover factors affecting their relationships. Postnatal women who had given birth during the previous 12 months were invited to participate in a cross-sectional online study. A comprehensive, multisection questionnaire, as well as the Relationship Assessment Scale (RAS), Female Sexual Function Index (FSFI), and Patient Health Questionnaire - 8 (PHQ-8), were used to collect data. Responses were analyzed using SPSS for Windows. Results showed that 37.2% of the participants experienced relationship dissatisfaction. Results of the multiple logistic regression revealed that the following were significant risk factors for relationship dissatisfaction during the first postpartum year: annual income of less than AU$50,000, sexual dysfunction, and a clinical diagnosis of depression and having symptoms of depression according to the PHQ-8 scores (p < 0.05). Compared to women in a heterosexual relationship, women who were in a same-sex relationship were less likely to have relationship dissatisfaction. In addition, in the period six to 12 months postpartum, women were less likely to have relationship dissatisfaction compared to the period 5 months or less postpartum (p < 0.05). PMID:26168298

    Objective: To investigate whether an increasing load of β-amyloid and/or neuritic plaques influences the phenotype, and thus the clinical diagnostic accuracy, of dementia with Lewy bodies (DLB). Methods: A series of 64 subjects with autopsy-proven DLB was studied. Last diagnosis before death was used to determine the clinical diagnostic accuracy of DLB in relation to Lewy body distribution and extent of Alzheimer β-amyloid and/or neuritic pathology. DLB pathologic diagnosis was made according to consensus criteria, using α-synuclein immunostaining for Lewy body identification. β-Amyloid immunostaining was used for quantifying β-amyloid deposits. The Consortium to Establish a Registry for Alzheimer's Disease criteria and Braak stage were applied for semiquantitative grading of neuritic plaque and neurofibrillary tangle pathology. Results: Overall clinical diagnostic accuracy for the entire DLB cohort was high (80%), reflecting the high prevalence of core clinical features (fluctuations [81%], parkinsonism [77%], visual hallucinations [70%]). Lower frequencies of core clinical features of DLB, resulting in lower accuracy of its clinical diagnosis, were associated with decreasing Lewy body distribution (p < 0.0001) and with increasing neuritic plaque pathology (p = 0.035), but not with the number of β-amyloid plaque deposits. Conclusions: The likelihood of occurrence of the DLB clinical syndrome is positively related to the extent of Lewy body pathology and negatively related to the severity of Alzheimer neuritic pathology, while β-amyloid load has no effect.

    In recent studies, habitat traits have emerged as stronger predictors of species occupancy, abundance, richness and diversity than competition. However, in many cases, it remains unclear whether habitat also mediates processes more subtle than competitive exclusion, such as growth, or whether intra- and interspecific interactions among individuals of different species may be better predictors of size. To test whether habitat traits are a stronger predictor of abundance and body size than intra- and interspecific interactions, we measured the density and body size of three species of larval salamanders in 192 ponds across a landscape. We found that the density of larvae was best predicted by models that included habitat features, while models incorporating interactions among individuals of different species best explained the body size of larvae. Additionally, we found a positive relationship between focal species density and congener density, while focal species body size was negatively related to congener density. We posit that salamander larvae may not experience competitive exclusion and thus reduced densities, but instead compensate for increased competition behaviourally (e.g. reduced foraging), resulting in decreased growth. The discrepancy between larval density and body size, a strong predictor of fitness in this system, also highlights a potential shortcoming in using density or abundance as a metric of habitat quality or population health.

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

    The mental representation of one's body typically implies the continuity of its parts. Here, we used immersive virtual reality to explore whether mere observation of visual discontinuity between the hand and limb of an avatar could influence a person's sense of ownership of the virtual body (feeling of ownership, FO) and being the agent of its actions (vicarious agency, VA). In experiment 1, we tested whether placing different amounts of visual discontinuity between a virtual hand and limb differently modulate the perceived FO and VA. Participants passively observed from a first-person perspective four different versions of a virtual limb: (1) a full limb; a hand detached from the proximal part of the limb because of deletion of (2) the wrist; (3) the wrist and forearm; (4) and the wrist, forearm and elbow. After observing the static or moving virtual limb, participants reported their feeling of ownership (FO) and vicarious agency (VA) over the hand. We found that even a small visual discontinuity between the virtual hand and arm significantly decreased participants' FO over the hand during observation of the static limb. Moreover, in the same condition, we found that passive observation of the avatar's actions induced a decrease in both FO and VA. We replicated the same results in a second study (experiment 2) where we investigated the modulation of FO and VA by comparing the visual body discontinuity with a condition in which the virtual limb was partially occluded. Our data show that mere observation of limb discontinuity can change a person's ownership and agency over a virtual body observed from a first-person perspective, even in the absence of any multisensory stimulation of the real body. These results shed new light on the role of body visual continuity in modulating self-awareness and agency in immersive virtual reality. PMID:25618006

    When we look at our hands we are immediately aware that they belong to us and we rarely doubt about the integrity, continuity and sense of ownership of our bodies. Here we explored whether the mere manipulation of the visual appearance of a virtual limb could influence the subjective feeling of ownership and the physiological responses (Skin Conductance Responses, SCRs) associated to a threatening stimulus approaching the virtual hand. Participants observed in first person perspective a virtual body having the right hand-forearm (i) connected by a normal wrist (Full-Limb) or a thin rigid wire connection (Wire) or (ii) disconnected because of a missing wrist (m-Wrist) or a missing wrist plus a plexiglass panel positioned between the hand and the forearm (Plexiglass). While the analysis of subjective ratings revealed that only the observation of natural full connected virtual limb elicited high levels of ownership, high amplitudes of SCRs were found also during observation of the non-natural, rigid wire connection condition. This result suggests that the conscious embodiment of an artificial limb requires a natural looking visual body appearance while implicit reactivity to threat may require physical body continuity, even non-naturally looking, that allows the implementation of protective reactions to threat.

    Current therapy for massive venous air embolism (VAE) includes the use of the left lateral recumbent (LLR) position. This recommendation is based on animal studies, conducted 50 years ago, which looked primarily at survival. Little is known, however, about the concomitant hemodynamic response after VAE in various body positions. The purpose of this study was to investigate the hemodynamic and cardiovascular changes in various body positions after VAE. Twenty-two mechanically ventilated supine mongrel dogs received a venous air infusion of 2.5 mL/kg at a rate of 5 mL/s. One minute after the infusion, 100% oxygen ventilation was commenced and the body position of the dogs was changed to either the LLR (n = 6), the LLR with the head 10 deg down (LLR-10 deg; n = 6) or the right lateral recumbent (RLR; n = 5) position. Five dogs were maintained in the supine position (SUP; n = 5). One dog died in every group except in the SUP group, where all the dogs recovered. There were no significant differences among the various body positions in terms of heart rate, mean arterial pressure, pulmonary artery pressure, central venous pressure, left ventricular end-diastolic pressure, or cardiac output. The acute hemodynamic changes occurring during the first 5-15 min after VAE recovered to 80% of control within 60 min. Our data suggest that body repositioning does not influence the cardiovascular response to VAE. Specifically, our data do not support the recommendation of repositioning into the LLR position for the treatment of VAE.

    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

    Foraging and migration often require different energetic and movement strategies. Though not readily apparent, constraints during one phase might influence the foraging strategies observed in another. For marine birds that fly and dive, body size constraints likely present a trade-off between foraging ability and migration as smaller bodies reduce flight costs, whereas larger bodies are advantageous for diving deeper. This study examines individual wintering strategies of deep diving thick-billed murres (Uria lomvia) breeding at three colonies in the south-eastern Bering Sea: St Paul, St George and Bogoslof. These colonies, arranged north to south, are located such that breeding birds forage in a gradient from shelf to deep-water habitats. We used geolocation time-depth recorders and stable isotopes from feathers to determine differences in foraging behaviour and diet of murres during three non-breeding periods, 2008-2011. Body size was quantified by a principal component analysis (wing, culmen, head+bill and tarsus length). A hierarchical cluster analysis identified winter foraging strategies based on individual movement, diving behaviour and diet (inferred from stable isotopes). Structural body size differed by breeding island. Larger birds from St Paul had higher wing loading than smaller birds from St George. Larger birds, mainly from St Paul, dove to deeper depths, spent more time in the Bering Sea, and likely consumed higher trophic-level prey in late winter. Three winter foraging strategies were identified. The main strategy, employed by small birds from all three breeding colonies in the first 2 years, was characterized by high residency areas in the North Pacific south of the Aleutians and nocturnal diving. In contrast, 31% of birds from St Paul remained in the Bering Sea and foraged mainly during the day, apparently feeding on higher trophic-level prey. Throat feather stable isotopes indicated that individuals exhibited flexibility in the use of this

    The sensitivities of five X-ray films commonly used for autoradiography of whole-body sections and thin-layer chromatograms were determined. The films tested were Kodak NS-2T, XAR-5, Industrex C, Agfa-Gevaert Osray M3 and CEAverken Singul-X. The order of sensitivity, from greatest to least, was found to be NS-2T, Osray M3, XAR-5, Singul-X and Industrex C. Increases in sensitivity following extended development were demonstrated for Industrex C. A literature review has revealed confusion in the use, in whole-body autoradiography, or various measures of autoradiographic response, which, in view of the simple relationship between radiographic optical density and absorbed dose, need not have arisen.

    Large valleys with opposing slopes may act as a model system with which the effects of strong climatic gradients on biodiversity can be evaluated. The advantage of such comparisons is that the impact of a change of climate can be studied on the same species pool without the need to consider regional differences. The aim of this study was to compare the assemblage of saproxylic beetles on such opposing slopes at Lower Nahal Oren, Mt. Carmel, Israel (also known as “Evolution Canyon”) with a 200–800% higher solar radiation on the south-facing (SFS) compared to the north-facing slope (NFS). We tested specific hypotheses of species richness patterns, assemblage structure, and body size resulting from interslope differences in microclimate. Fifteen flight-interception traps per slope were distributed over three elevation levels ranging from 50 to 100 m a.s.l. Richness of saproxylic beetles was on average 34% higher on the SFS compared with the NFS, with no detected influence of elevation levels. Both assemblage structure and average body size were determined by slope aspect, with more small-bodied beetles found on the SFS. Both the increase in species richness and the higher prevalence of small species on the SFS reflect ecological rules present on larger spatial grain (species-energy hypothesis and community body size shift hypothesis), and both can be explained by the metabolic theory of ecology. This is encouraging for the complementary use of micro- and macroclimatic gradients to study impacts of climate warming on biodiversity. PMID:26047491

    Rectal probe thermometry is commonly used to measure body core temperature in rodents because of its ease of use. Although previous studies suggest that rectal measurement is stressful and results in long-lasting elevations in body temperatures, we evaluated how this procedure affects brain, muscle, skin and core temperatures measured with chronically implanted thermocouple electrodes in rats. Our data suggest that the procedure of rectal measurement results in powerful locomotor activation, rapid and strong increases in brain, muscle, and deep body temperatures, as well as a biphasic, down-up fluctuation in skin temperature, matching the response pattern observed during tail-pinch, a representative stressful procedure. This response, moreover, did not habituate after repeated day-to-day testing. Repeated rectal probe insertions also modified temperature responses induced by intravenous cocaine. Under quiet resting conditions, cocaine moderately increased brain, muscle and deep body temperatures. However, during repeated rectal measurements, which increased temperatures, cocaine induced both hyperthermic and hypothermic responses. Direct comparisons revealed that body temperatures measured by a rectal probe are typically lower (∼0.6°C) and more variable than body temperatures recorded by chronically implanted electrodes; the difference is smaller at low and greater at high basal temperatures. Because of this difference and temperature increases induced by the rectal probe per se, cocaine had no significant effect on rectal temperatures compared to control animals exposed to repeated rectal probes. Therefore, although rectal temperature measurements provide a decent correlation with directly measured deep body temperatures, the arousing influence of this procedure may drastically modulate the effects of other arousing stimuli and drugs.

    Findings regarding the link between body image and sexuality have been equivocal, possibly because of the insensitivity of many of body image measures to potential variability across sensory aspects of the body (e.g., appearance versus odor), individual body parts (e.g., genitalia versus thighs), and social settings (e.g., public versus intimate). The current study refined existing methods of evaluating women's body image in the context of sexuality by focusing upon two highly specified dimensions: satisfaction with the visual appearance of the genitalia and self-consciousness about the genitalia during a sexual encounter. Genital appearance dissatisfaction, genital image self-consciousness, and multiple facets of sexuality were examined with a sample of 217 undergraduate women using an online survey. Path analysis revealed that greater dissatisfaction with genital appearance was associated with higher genital image self-consciousness during physical intimacy, which, in turn, was associated with lower sexual esteem, sexual satisfaction, and motivation to avoid risky sexual behavior. These findings underscore the detrimental impact of negative genital perceptions on young women's sexual wellbeing, which is of particular concern given their vulnerability at this stage of sexual development as well as the high rates of sexually transmitted infections within this age group. Interventions that enhance satisfaction with the natural appearance of their genitalia could facilitate the development of a healthy sexual self-concept and provide long-term benefits in terms of sexual safety and satisfaction.

    Weight dissatisfaction, body dissatisfaction, and body-image distortion measures were used with 98 fifth and eighth graders and 57 undergraduate students. Measures included the Piers-Harris Self-concept Scale and the Kids Eating Disorder Survey for the young children, the Interpersonal Behavior Survey, and a seven-item mistaken beliefs scale for the college sample. Body dissatisfaction and Body-image distortion were assessed with a figure-drawing procedure. Significant differences in both weight dissatisfaction and body dissatisfaction were found between males and females in the eighth grade and undergraduate groups. There were no significant sex differences in body-image distortion in the fifth or eighth grades, but significant differences in body-image distortion between men and women were found in the college sample. The direction of body-image distortion for both the 20 men and the 37 women was consistent with their ideal weight. In the college sample, there was a significant correlation between body-image dissatisfaction and self-confidence for the women but not for the men. PMID:9885045

    Teacher satisfaction can be reflected in the success of higher education institutions to provide meaningful learning to their students. This study analyzed the professional satisfaction of nutrition teachers at a federal institution of higher education by identifying the factors that generated satisfaction and dissatisfaction for them and also the feelings that they envisioned for themselves at the end of their careers. This is a descriptive and exploratory study with a qualitative approach. A questionnaire and semi-structured interviews were performed. The results showed that 72.7% of the teachers were satisfied with their profession. In relation to satisfaction were considered: the fulfillment of a vocation; research and extension activities; the development and recognition of students and society; learning; autonomy; flexibility; and relationships with students. In relation to dissatisfaction were considered: overloading due to work, administration, bureaucratic duties and assistance; lack of interest and respect from students; relationships with colleagues and managers; devaluation in the role of teaching; large classes and poor physical infrastructure. The respondents expressed a positive attitude and had no desire to leave their profession. Further studies are required regarding factors leading to satisfaction and dissatisfaction for teachers, in order to contribute to their productivity and well-being. PMID:27557009

  18. Mortality affects adaptive allocation to growth and reproduction: field evidence from a guild of body snatchers

    PubMed Central

    2010-01-01

    Background The probability of being killed by external factors (extrinsic mortality) should influence how individuals allocate limited resources to the competing processes of growth and reproduction. Increased extrinsic mortality should select for decreased allocation to growth and for increased reproductive effort. This study presents perhaps the first clear cross-species test of this hypothesis, capitalizing on the unique properties offered by a diverse guild of parasitic castrators (body snatchers). I quantify growth, reproductive effort, and expected extrinsic mortality for several species that, despite being different species, use the same species' phenotype for growth and survival. These are eight trematode parasitic castrators—the individuals of which infect and take over the bodies of the same host species—and their uninfected host, the California horn snail. Results As predicted, across species, growth decreased with increased extrinsic mortality, while reproductive effort increased with increased extrinsic mortality. The trematode parasitic castrator species (operating stolen host bodies) that were more likely to be killed by dominant species allocated less to growth and relatively more to current reproduction than did species with greater life expectancies. Both genders of uninfected snails fit into the patterns observed for the parasitic castrator species, allocating as much to growth and to current reproduction as expected given their probability of reproductive death (castration by trematode parasites). Additionally, species differences appeared to represent species-specific adaptations, not general plastic responses to local mortality risk. Conclusions Broadly, this research illustrates that parasitic castrator guilds can allow unique comparative tests discerning the forces promoting adaptive evolution. The specific findings of this study support the hypothesis that extrinsic mortality influences species differences in growth and reproduction

    Stimulation of Type II taste receptor cells (TRCs) with T1R taste receptors causes sweet or umami taste, whereas T2Rs elicit bitter taste. Type II TRCs contain the calcium channel, calcium homeostasis modulator protein 1 (CALHM1), which releases adenosine triphosphate (ATP) transmitter to taste fibers. We have previously demonstrated with chorda tympani nerve recordings and two-bottle preference (TBP) tests that mice with genetically deleted Calhm1 (knockout [KO]) have severely impaired perception of sweet, bitter, and umami compounds, whereas their sour and salty tasting ability is unaltered. Here, we present data from KO mice of effects on glossopharyngeal (NG) nerve responses, TBP, food intake, body weight, and life span. KO mice have no NG response to sweet and a suppressed response to bitter compared with control (wild-type [WT]) mice. KO mice showed some NG response to umami, suggesting that umami taste involves both CALHM1- and non-CALHM1-modulated signals. NG responses to sour and salty were not significantly different between KO and WT mice. Behavioral data conformed in general with the NG data. Adult KO mice consumed less food, weighed significantly less, and lived almost a year longer than WT mice. Taken together, these data demonstrate that sweet taste majorly influences food intake, body weight, and life span. PMID:25855639

    It has been suggested that action possibility judgements are formed through a covert simulation of the to-be-executed action. We sought to determine whether the motor system (via a common coding mechanism) influences this simulation, by investigating whether action possibility judgements are influenced by experience with the movement task (Experiments 1 and 2) and current body states (Experiment 3). The judgement task in each experiment involved judging whether it was possible for a person's hand to accurately move between two targets at presented speeds. In Experiment 1, participants completed the action judgements before and after executing the movement they were required to judge. Results were that judged movement times after execution were closer to the actual execution time than those prior to execution. The results of Experiment 2 suggest that the effects of execution on judgements were not due to motor activation or perceptual task experience-alternative explanations of the execution-mediated judgement effects. Experiment 3 examined how judged movement times were influenced by participants wearing weights. Results revealed that wearing weights increased judged movement times. These results suggest that the simulation underlying the judgement process is connected to the motor system, and that simulations are dynamically generated, taking into account recent experience and current body state.

    Small nuclear ribonucleoproteins (snRNPs), which are required for pre-mRNA splicing, contain extensively modified snRNA. Small Cajal body-specific ribonucleoproteins (scaRNPs) mediate these modifications. It is unknown how the box C/D class of scaRNPs localizes to Cajal Bodies (CBs). The processing of box C/D scaRNA is also unclear. Here, we explore the processing of box C/D scaRNA 2 and 9 by coilin. We also broaden our investigation to include WRAP53 and SMN, which accumulate in CBs, play a role in RNP biogenesis and associate with coilin. These studies demonstrate that the processing of an ectopically expressed scaRNA2 is altered upon the reduction of coilin, WRAP53 or SMN, but the extent and direction of this change varies depending on the protein reduced. We also show that box C/D scaRNP activity is reduced in a cell line derived from coilin knockout mice. Collectively, the findings presented here further implicate coilin as being a direct participant in the formation of box C/D scaRNPs, and demonstrate that WRAP53 and SMN may also play a role, but the activity of these proteins is divergent to coilin.

    Beneficial health properties of garlic, as well as its most common adverse effect - distinctive breath odour - are well-known. In contrast, analogous research on the effect of garlic on axillary odour is currently missing. Here, in three studies varying in the amount and nature of garlic provided (raw garlic in study 1 and 2, garlic capsules in study 3), we tested the effect of garlic consumption on the quality of axillary odour. A balanced within-subject experimental design was used. In total, 42 male odour donors were allocated to either a "garlic" or "non-garlic" condition, after which they wore axillary pads for 12 h to collect body odour. One week later, the conditions were reversed. Odour samples were then judged for their pleasantness, attractiveness, masculinity and intensity by 82 women. We found no significant differences in ratings of any characteristics in study 1. However, the odour of donors after an increased garlic dosage was assessed as significantly more pleasant, attractive and less intense (study 2), and more attractive and less intense in study 3. Our results indicate that garlic consumption may have positive effects on perceived body odour hedonicity, perhaps due to its health effects (e.g., antioxidant properties, antimicrobial activity).

    Pulmonary surfactant (PS) is a surface active complex of lipids and proteins that prevents the alveolar structures from collapsing and reduces the work of breathing by lowering the surface tension at the alveolar air-liquid interface (ALI). Surfactant is synthesized by the alveolar type II (AT II) cells, and it is stored in specialized organelles, the lamellar bodies (LBs), as tightly packed lipid bilayers. Upon secretion into the alveolar lining fluid, a large fraction of these particles retain most of their packed lamellar structure, giving rise to the term lamellar body like-particles (LBPs). Due to their stability in aqueous media, freshly secreted LBPs can be harvested from AT II cell preparations. However, when LBPs get in contact with an ALI, they quickly and spontaneously adsorb into a highly organized surface film. In the present study we investigated the adsorptive capacity of LBPs at an ALI under relevant physiological parameters that characterize the alveolar environment in homeostatic or in pathological conditions. Adsorption of LBPs at an ALI is highly sensitive to pH, temperature and albumin concentration and to a relatively lesser extent to changes in osmolarity or Ca(2+) concentrations in the physiological range. Furthermore, proteolysis of LBPs significantly decreases their adsorptive capacity confirming the important role of surfactant proteins in the formation of surface active films. PMID:24582711

    Apolipoprotein A-II (APOA2) is one of the major constituents of high-density lipoprotein and plays a critical role in lipid metabolism and obesity. However, similar research for the bovine APOA2 gene is lacking. In this study, polymorphisms of the bovine APOA2 gene and its promoter region were detected in 1021 cows from four breeds by sequencing and PCR-RFLP methods. Totally, we detected six novel mutations which included one mutation in the promoter region, two mutations in the exons and three mutations in the introns. There were four polymorphisms within APOA2 gene were analyzed. The allele A, T, T and G frequencies of the four loci were predominant in the four breeds when in separate or combinations analysis which suggested cows with those alleles to be more adapted to the steppe environment. The association analysis indicated three SVs in Nangyang cows, two SVs in Qinchun cows and the 9 haplotypes in Nangyang cows were significantly associated with body traits (P<0.05 or P<0.01). The results of this study suggested the bovine APOA2 gene may be a strong candidate gene for body traits in the cattle breeding program. PMID:24004543

    Lead poisoning, through the ingestion of spent lead gunshot, is an established cause of morbidity and mortality in waterbirds globally, but the thresholds at which blood levels begin to affect the physiology of birds in the wild are less well known. Here we determine the prevalence of lead exposure in whooper swans and, for the first time, identify the level of blood lead associated with initial reductions in body condition. Blood lead elevated above background levels (i.e. >20 μg dL(-1)) was found in 41.7% (125/300) of swans tested. Blood lead was significantly negatively associated with winter body condition when levels were ≥44 μg dL(-1) (27/260 = 10%). Our findings indicating that sub-lethal impacts of lead on body condition occur at the lower end of previously established clinical thresholds and that a relatively high proportion of individuals in this population may be affected, reaffirm the importance of reducing contamination of the environment with lead shot.

    Dietary lysine restriction may differentially affect body growth and lipid and nitrogen metabolism, depending on the degree of lysine restriction. This study was conducted to examine the effect of dietary lysine restriction on growth and lipid and nitrogen metabolism with two different degree of lysine restriction. Isocaloric amino acid-defined diets containing 1.4% lysine (adequate), 0.70% lysine (50% moderate lysine restriction) and 0.35% lysine (75% severe lysine restriction) were fed from the age of 52 to 77 days for 25 days in male Sprague-Dawley rats. The 75% severe lysine restriction increased (p < 0.05) food intake, but retarded (p < 0.05) growth, increased (p < 0.05) liver and muscle lipid contents and abdominal fat accumulation, increased (p < 0.05) blood urea nitrogen levels and mRNA levels of the serine-synthesizing 3-phosphoglycerate dehydrogenase gene, but decreased (p < 0.05) urea cycle arginase gene mRNA levels. In contrast, the 50% lysine restriction did not significantly (p > 0.05) affect body growth and lipid and nitrogen metabolism. Our results demonstrate that severe 75% lysine restriction has detrimental effects on body growth and deregulate lipid and nitrogen metabolism. PMID:23441935

    The effect of a relatively common chronic disease, severe dental caries, affects young childrens' growth and well-being. Treating dental caries in pre-school children would increase growth rates and the quality of life of millions of children. Severe untreated dental caries is common in pre-school children in many countries. Children with severe caries weighed less than controls, and after treatment of decayed teeth there was more rapid weight gain and improvements in their quality of life. This may be due to dietary intake improving because pain affected the quantity and variety of food eaten, and second, chronic inflammation from caries related pulpitis and abscesses is known to suppress growth through a metabolic pathway and to reduce haemoglobin as a result of depressed erythrocyte production.

    The simultaneous perception of multimodal sensory information has a crucial role for effective reactions to the external environment. Voluntary movements are known to occasionally affect simultaneous perception of auditory and tactile stimuli presented to the moving body part. However, little is known about spatial limits on the effect of voluntary movements on simultaneous perception, especially when tactile stimuli are presented to a non-moving body part. We examined the effect of voluntary movement on the simultaneous perception of auditory and tactile stimuli presented to the non-moving body part. We considered the possible mechanism using a temporal order judgement task under three experimental conditions: voluntary movement, where participants voluntarily moved their right index finger and judged the temporal order of auditory and tactile stimuli presented to their non-moving left index finger; passive movement; and no movement. During voluntary movement, the auditory stimulus needed to be presented before the tactile stimulus so that they were perceived as occurring simultaneously. This subjective simultaneity differed significantly from the passive movement and no movement conditions. This finding indicates that the effect of voluntary movement on simultaneous perception of auditory and tactile stimuli extends to the non-moving body part. PMID:27622584

    2015-01-01

    The brain is considered to be the primary generator and regulator of emotions; however, afferent signals originating throughout the body are detected by the autonomic nervous system (ANS) and brainstem, and, in turn, can modulate emotional processes. During stress and negative emotional states, levels of cardiorespiratory coherence (CRC) decrease, and a shift occurs toward sympathetic dominance. In contrast, CRC levels increase during more positive emotional states, and a shift occurs toward parasympathetic dominance. The dynamic changes in CRC that accompany different emotions can provide insights into how the activity of the limbic system and afferent feedback manifest as emotions. The authors propose that the brainstem and CRC are involved in important feedback mechanisms that modulate emotions and higher cortical areas. That mechanism may be one of many mechanisms that underlie the physiological and neurological changes that are experienced during pranayama and meditation and may support the use of those techniques to treat various mood disorders and reduce stress.

    The authors analyze male sexual initiation as a time of acquiring knowledge, based on 62 ethnographic interviews with young men (18-24 years) in the cities of Porto Alegre, Rio de Janeiro, and Salvador, Brazil, as a stage in the GRAVAD Research Project. Adopting an anthropological and comparative perspective, the reports show that men's first sexual experience is a process of physical and social learning by which they acquire technical knowledge on the use of their bodies and skill to relate to others, especially women. These are important milestones in the passage to adulthood. In addition to differences in belonging to various socioeconomic segments, the authors focus on gender relations, especially models of masculinity, demonstrating that a young man's first sexual intercourse is a socially and symbolically striking moment, not limited to a single event, but an experience that involves different levels of learning as part of the process of becoming a man.

    Over the past century, body dysmorphic disorder (BDD), a preoccupation with an imagined or slight defect in appearance, has been hypothesized to be related to obsessive-compulsive disorder (OCD). More recently, BDD has also been hypothesized to be a form of affective spectrum disorder. Affective spectrum disorder refers to a family of disorders postulated to have a common pathophysiologic abnormality. This grouping of disorders has been identified on the basis of their response to pharmacologic treatments and is supported by comorbidity and family studies. Available data suggest that BDD should be considered a candidate form of affective spectrum disorder--a disorder that may eventually be demonstrated to belong to this family of disorders. Available data also strongly support the hypothesis that BDD is an obsessive-compulsive spectrum disorder. Because OCD itself has been hypothesized to be an affective spectrum disorder, BDD may be more narrowly conceptualized as an obsessive-compulsive spectrum disorder and more broadly as a candidate form of affective spectrum disorder.

    The presence of peritoneal dialysate when performing bioimpedance analysis may affect body composition measurements. The aim of this study was to evaluate the impact of dialysate on body composition measurements in Asians. Forty-one patients undergoing maintenance peritoneal dialysis in our hospital peritoneal dialysis unit were included in this study. Dialysate was drained from the abdomen prior to measurement, and bioimpedance analysis was performed using multi-frequency bioimpedance analysis, with each subject in a standing position (D-). Dialysate was then administered and the measurement was repeated (D+). The presence of peritoneal dialysate led to an increase in intracellular water (ICW), extracellular water (ECW), and total body water (D-: 20.33 ± 3.72 L for ICW and 13.53 ± 2.54 L for ECW; D+: 20.96 ± 3.78 L for ICW and 14.10 ± 2.59 L for ECW; P < 0.001 for both variables). Total and trunk oedema indices were higher in the presence of peritoneal dialysate. In addition, the presence of peritoneal dialysate led to an overestimation of mineral content and free fat mass (FFM) for the total body; but led to an underestimation of body fat (D-: 45.80 ± 8.26 kg for FFM and 19.30 ± 6.27 kg for body fat; D+: 47.51 ± 8.38 kg for FFM and 17.59 ± 6.47 kg for body fat; P < 0.001 for both variables). Our results demonstrate that the presence of peritoneal dialysate leads to an overestimation of FFM and an underestimation of fat mass. An empty abdomen is recommended when evaluating body composition using bioimpedance analysis. PMID:25307155

  15. Psychogenic fever: how psychological stress affects body temperature in the clinical population

    Psychogenic fever is a stress-related, psychosomatic disease especially seen in young women. Some patients develop extremely high core body temperature (Tc) (up to 41°C) when they are exposed to emotional events, whereas others show persistent low-grade high Tc (37–38°C) during situations of chronic stress. The mechanism for psychogenic fever is not yet fully understood. However, clinical case reports demonstrate that psychogenic fever is not attenuated by antipyretic drugs, but by psychotropic drugs that display anxiolytic and sedative properties, or by resolving patients' difficulties via natural means or psychotherapy. Animal studies have demonstrated that psychological stress increases Tc via mechanisms distinct from infectious fever (which requires proinflammatory mediators) and that the sympathetic nervous system, particularly β3-adrenoceptor-mediated non-shivering thermogenesis in brown adipose tissue, plays an important role in the development of psychological stress-induced hyperthermia. Acute psychological stress induces a transient, monophasic increase in Tc. In contrast, repeated stress induces anticipatory hyperthermia, reduces diurnal changes in Tc, or slightly increases Tc throughout the day. Chronically stressed animals also display an enhanced hyperthermic response to a novel stress, while past fearful experiences induce conditioned hyperthermia to the fear context. The high Tc that psychogenic fever patients develop may be a complex of these diverse kinds of hyperthermic responses. PMID:27227051

    Objective The objective of this study was to determine the effect of body mass index (BMI) during pregnancy in laboratory parameters in the serum of the three groups of pregnant women and in their newborns. Methods This prospective study is comparison between the three groups of pregnant women and their newborns categorized according to their BMI. The study included 128 pregnant women and their newborns. In this study, the concentration of blood count, iron, ferritin, and bilirubin were analyzed in the subjects. Results The pregnant women in the three groups significantly differ in the values of blood count (p < 0.001). Statistically significant difference in iron and ferritin was not found between individual three studied groups of pregnant women (p = 0.947). The newborn of the first group of pregnant women had significantly lower values of ferritin (p < 0.001), leucocytes (p < 0.001), and bilirubin (p < 0.001). Significant positive correlation between BMI of pregnant women and leucocytes, ferritin, and bilirubin of the newborn was found (p < 0.001). Conclusion In this study, the tested pregnant women do not have biochemical signs of anemia, neither do their newborns. It was noted that there was no negative correlation between individual tested biochemical parameters for anemia in pregnant women and their newborns. PMID:27119047

    Low pathogenic avian influenza (LPAI) viruses are well documented to circulate within wild waterfowl populations (Olsen et al. 2006). It has been assumed that these infections are benign with no subsequent effects on life-history parameters. The study by Latorre-Margalef et al. (2009; hereafter L.-M. et al.) represents an important step, as they attempt to test this assumption in wild birds. L.-M. et al. captured migrating mallards (Anas platyrhynchos) at a staging area and tested them for the presence of avian influenza A virus (IAV). They related IAV infection status to body mass and duration of time spent on the staging area. Overall, the study is well designed with impressive sample sizes and the analyses are carefully conducted and presented. However, in discussing these results, the authors assume causation based upon correlation and, although they acknowledge the possibility of immunosuppression during migration due to reduced energy stores, they do not discuss it as a possible explanation for their findings. Below, we consider several of the major findings by L.-M. et al., providing alternative explanations for the results. Because the L.-M. et al. study design is correlational, it is not possible to use their data to distinguish between their interpretations and our alternative explanations.

  18. A review of anatomical and mechanical factors affecting vertebral body integrity

    PubMed Central

    2004-01-01

    Background: The aetiology of osteoporotic vertebral fracture is multifactorial and may be conceptualised using a systems framework. Previous studies have established several correlates of vertebral fracture including reduced vertebral cross-sectional area, weakness in back extensor muscles, reduced bone mineral density, increasing age, worsening kyphosis and recent vertebral fracture. Alterations in these physical characteristics may influence biomechanical loads and neuromuscular control of the trunk and contribute to changes in subregional bone mineral density of the vertebral bodies. Methods: This review discusses factors that have received less attention in the literature, which may contribute to the development of vertebral fracture. A literature review was conducted using electronic databases including Medline, Cinahl and ISI Web of Science to examine the potential contribution of trabecular architecture, subregional bone mineral density, vertebral geometry, muscle force, muscle strength, neuromuscular control and intervertebral disc integrity to the aetiology of osteoporotic vertebral fracture. Interpretation: A better understanding of factors such as biomechanical loading and neuromuscular control of the trunk may help to explain the high incidence of subsequent vertebral fracture after sustaining an initial vertebral fracture. Consideration of these issues may be important in the development of prevention and management strategies. PMID:15912196

    Emotion perception naturally entails multisensory integration. It is also assumed that multisensory emotion perception is characterized by enhanced activation of brain areas implied in multisensory integration, such as the superior temporal gyrus and sulcus (STG/STS). However, most previous studies have employed designs and stimuli that preclude other forms of multisensory interaction, such as crossmodal prediction, leaving open the question whether classical integration is the only relevant process in multisensory emotion perception. Here, we used video clips containing emotional and neutral body and vocal expressions to investigate the role of crossmodal prediction in multisensory emotion perception. While emotional multisensory expressions increased activation in the bilateral fusiform gyrus (FFG), neutral expressions compared to emotional ones enhanced activation in the bilateral middle temporal gyrus (MTG) and posterior STS. Hence, while neutral stimuli activate classical multisensory areas, emotional stimuli invoke areas linked to unisensory visual processing. Emotional stimuli may therefore trigger a prediction of upcoming auditory information based on prior visual information. Such prediction may be stronger for highly salient emotional compared to less salient neutral information. Therefore, we suggest that multisensory emotion perception involves at least two distinct mechanisms; classical multisensory integration, as shown for neutral expressions, and crossmodal prediction, as evident for emotional expressions.

    In mammals, the mass-specific rate of biomass production during gestation and lactation, here called maternal productivity, has been shown to vary with body size and lifestyle. Metabolic theory predicts that post-weaning growth of offspring, here termed juvenile productivity, should be higher than maternal productivity, and juveniles of smaller species should be more productive than those of larger species. Furthermore because juveniles generally have similar lifestyles to their mothers, across species juvenile and maternal productivities should be correlated. We evaluated these predictions with data from 270 species of placental mammals in 14 taxonomic/lifestyle groups. All three predictions were supported. Lagomorphs, perissodactyls and artiodactyls were very productive both as juveniles and as mothers as expected from the abundance and reliability of their foods. Primates and bats were unproductive as juveniles and as mothers, as expected as an indirect consequence of their low predation risk and consequent low mortality. Our results point the way to a mechanistic explanation for the suite of correlated life-history traits that has been called the slow–fast continuum. PMID:24403339

    After the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi nuclear power plant accident, the Tokai Research and Development Center of the Japan Atomic Energy Agency (JAEA) have had direct dialogue as risk communication with Fukushima residents who underwent whole-body counting examination (WBC). The purpose of the risk communication was to exchange information and opinions about radiation in order to mitigate Fukushima residents' anxiety and stress. Two kinds of opinion surveys were performed: one survey evaluated residents' views of the nuclear accident itself and the second survey evaluated the management of WBC examination as well as the quality of JAEA's communication skills on risks. It appears that most Fukushima residents seem to have reduced their anxiety level after the direct dialogue. The results of the surveys show that Fukushima residents have the deepest anxiety and concern about their long-term health issues and that they harbor anger toward the government and TEPCO. On the other hand, many WBC patients and patients' relatives have expressed gratitude for help in reducing their feelings of anxiety.

  3. Overexpression of diacylglycerol acyltransferase in Yarrowia lipolytica affects lipid body size, number and distribution.

    In the oleaginous yeast Yarrowia lipolytica, the diacylglycerol acyltransferases (DGATs) are major factors for triacylglycerol (TAG) synthesis. The Q4 strain, in which the four acyltransferases have been deleted, is unable to accumulate lipids and to form lipid bodies (LBs). However, the expression of a single acyltransferase in this strain restores TAG accumulation and LB formation. Using this system, it becomes possible to characterize the activity and specificity of an individual DGAT. Here, we examined the effects of DGAT overexpression on lipid accumulation and LB formation in Y. lipolytica Specifically, we evaluated the consequences of introducing one or two copies of the Y. lipolytica DGAT genes YlDGA1 and YlDGA2 Overall, multi-copy DGAT overexpression increased the lipid content of yeast cells. However, the size and distribution of LBs depended on the specific DGAT overexpressed. YlDGA2 overexpression caused the formation of large LBs, while YlDGA1 overexpression generated smaller but more numerous LBs. This phenotype was accentuated through the addition of a second copy of the overexpressed gene and might be linked to the distinct subcellular localization of each DGAT, i.e. YlDga1 being localized in LBs, while YlDga2 being localized in a structure strongly resembling the endoplasmic reticulum.

  4. Automatic evaluation of body-related words among young women: an experimental study

    PubMed Central

    2010-01-01

    Background Previous research has demonstrated that exposure to images depicting the thin female ideal has negative effects on some females' levels of body dissatisfaction. Much of this research, however, has utilised relatively long stimulus exposure times; thereby focusing on effortful and conscious processing of body-related stimuli. Relatively little is known about the nature of females' affective responses to the textual components of body-related stimuli, especially when these stimuli are only briefly encountered. The primary aim of the current research was to determine whether young women automatically evaluate body-related words and whether these responses are associated with body image concerns, including self-reported levels of appearance schematicity, thin internalisation, body dissatisfaction, and dietary restraint. Methods An affective priming task was used to investigate whether females automatically evaluate body-related words, and whether this is associated with self-reported body image concerns. In a within-participants experimental design, the valence congruence of the prime and target pairs was manipulated. Participants selected body words as primes in Experiment 1 (N = 27), while normatively selected body words were primes in Experiment 2 (N = 50). Each prime was presented briefly, followed by a target word which participants judged as "good" or "bad". The dependent variable was response latency to the target. Results Automatic evaluation was evident: responding to congruent pairs was faster than responding to incongruent pairs. Body image concerns were unrelated to automaticity. Conclusions The findings suggest that brief encounters with body words are likely to prompt automatic evaluation in all young women, and that this process proceeds unintentionally and efficiently, without conscious guidance.

    Purpose Robotic Stereotactic Body Radiation Therapy with real-time tumor tracking has shown encouraging results for hepatic tumors with good efficacy and low toxicity. We studied the factors associated with local control of primary or secondary hepatic lesions post-SBRT. Methods and materials Since 2007, 153 stereotactic liver treatments were administered to 120 patients using the CyberKnife® System. Ninety-nine liver metastases (72 patients), 48 hepatocellular carcinomas (42 patients), and six cholangiocarcinomas were treated. On average, three to four sessions were delivered over 12 days. Twenty-seven to 45 Gy was prescribed to the 80% isodose line. Margins consisted of 5 to 10 mm for clinical target volume (CTV) and 3 mm for planning target volume (PTV). Results Median size was 33 mm (range, 5–112 mm). Median gross tumor volume (GTV) was 32.38 cm3 (range, 0.2–499.5 cm3). Median total dose was 45 Gy in three fractions. Median minimum dose was 27 Gy in three fractions. With a median follow-up of 15.0 months, local control rates at one and two years were 84% and 74.6%, respectively. The factors associated with better local control were lesion size < 50 mm (p = 0.019), GTV volume (p < 0.05), PTV volume (p < 0.01) and two treatment factors: a total dose of 45 Gy and a dose–per-fraction of 15 Gy (p = 0.019). Conclusions Dose, tumor diameter and volume are prognostic factors for local control when a stereotactic radiation therapy for hepatic lesions is considered. These results should be considered in order to obtain a maximum therapeutic efficacy. PMID:23050794

    The objective of the present study was to identify and quantify several factors affecting shrink in cattle during commercial long-haul transport (≥400 km; n = 6,152 journeys). Surveys were designed and delivered to transport carriers to collect relevant information regarding the characteristics of animals, time of loading, origin and destination, and loaded weight before and after transport. In contrast to fat cattle, feeder cattle exhibited greater shrink (4.9 vs. 7.9 ± 0.2% of BW, respectively; P < 0.01), and experienced longer total transport durations (12.4 vs. 14.9 ± 0.99, respectively; P < 0.01) due to border crossing protocols which require mandatory animal inspection. Shrink was greater (P < 0.001) for feeder cattle loaded at ranches/farms and feed yards compared with those loaded at auction markets. Cattle loaded during the afternoon and evening shrank more than those loaded during the night and morning (P < 0.05). Shrinkage was less in cattle transported by truck drivers having 6 or more years of experience hauling livestock compared with those with 5 yr or less (P < 0.05). Shrink increased with both midpoint ambient temperature (% of BW/°C; P < 0.001) and time on truck (% of BW/h; P < 0.001). Temperature and time on truck had a multiplicative effect on each other because shrink increased most rapidly in cattle transported for both longer durations and at higher ambient temperatures (P < 0.001). The rate of shrink over time (% of BW/h) was greatest in cull cattle, intermediate in calves and feeder cattle, and slowest in fat cattle (P < 0.05) but such differences disappeared when the effects of place of origin, loading time, and experience of truck drivers were included in the model. Cull cattle, calves and feeder cattle appear to be more affected by transport compared with fat cattle going to slaughter because of greater shrink. Several factors should be considered when developing guidelines to reduce cattle transport stress and shrink including type

    Obesity and type 2 diabetes constitute leading public health problems worldwide. Studies have shown that insulin resistance affiliated with these conditions is associated with skeletal muscle lipid accumulation, while the latter is associated with mitochondrial dysfunctions. However, the initiation and regulation of mitochondrial biogenesis rely heavily on approximately 1000 nuclear-encoded mitochondrial regulatory proteins. In this study, we targeted the ubiquinol-cytochrome c reductase core protein I gene, a nuclear-encoded component of mitochondrial complex III, for its association with subcutaneous fat depth (SFD) and skeletal muscle lipid accumulation (SMLA) using cattle as a model. Four promoter polymorphisms were identified and genotyped on approximately 250 Wagyu x Limousin F2 progeny. Statistical analysis revealed that two completely linked polymorphic sites, g.13487C>T and g.13709G>C (r2 = 1), were significantly associated with both SFD (p < 0.01) and SMLA (p < 0.0001). The difference between TTCC and CCGG haplotypes was 0.178 cm for SFD and 0.624 scores for SMLA. Interestingly, the former haplotype produced higher promoter activities than the latter by 43% to 49% in three cell lines (p < 0.05). In addition to Rett syndrome and breast/ovarian cancer observed in other studies, we report evidence for the first time, to our knowledge, that overexpression of ubiquinol-cytochrome c reductase core protein I might affect mitochondrial morphology and/or physiology and lead to development of obesity and related conditions.

    Helicobacter pylori, is an invariably commensal resident of the gut microbiome associated with gastric ulcer in adults. In addition, these patients also suffered from a low grade inflammation that activates the immune system and thus increased shunting of energy to host defense mechanisms. To assess whether a H. pylori infection could affect growth in early life, we determined the expression levels of selected metabolic gut hormones in germ free (GF) and specific pathogen-free (SPF) mice with and without the presence of H. pylori. Despite H. pylori-infected (SPFH) mice display alteration in host metabolism (elevated levels of leptin, insulin and peptide YY) compared to non-infected SPF mice, their growth curves remained the same. SPFH mice also displayed increased level of eotaxin-1. Interestingly, GF mice infected with H. pylori (GFH) also displayed increased levels of ghrelin and PYY. However, in contrast to SPFH mice, GFH showed reduced weight gain and malnutrition. These preliminary findings show that exposure to H. pylori alters host metabolism early in life; but the commensal microbiota in SPF mice can attenuate the growth retarding effect from H. pylori observed in GF mice. Further investigations of possible additional side effects of H. pylori are highly warranted. PMID:25736205

    2016-05-01

    The impact of body condition at 110 d of gestation on mammary gland development, mammary gene expression, and hormonal and metabolite status of gilts was studied. Thirty-nine gilts were equally divided into 3 groups based on their backfat thickness at the end of gestation: 1) low backfat (LBF; 12-15 mm), 2) medium backfat (MBF; 17-19 mm), or 3) high backfat (HBF; 21-26 mm). Gilts had similar BW (138.1 ± 8.2 kg) and backfat thicknesses (16.4 ± 1.0 mm) at mating and the 3 groups were achieved via ingestion of varying amounts of feed throughout gestation. Jugular blood samples were obtained from all gilts at mating and at 109 d of gestation to assess hormonal and metabolic statuses, and animals were slaughtered on d 110 to collect mammary glands for compositional analyses and for measure of gene expression. The LBF gilts had less extraparenchymal tissue ( < 0.01) and parenchymal tissue ( < 0.05) than HBF gilts. Mammary parenchyma from LBF gilts also tended to contain less DM ( < 0.10), contained more protein ( < 0.05), and had greater RNA concentrations ( < 0.01) than that from HBF gilts. None of the 15 genes studied in mammary parenchymal tissue differed in terms of expression level, and the rate of mammary cell proliferation was similar among treatments ( > 0.10). There was a tendency for circulating leptin concentrations on d 109 of gestation to be lower in LBF gilts than in MBF gilts ( < 0.10), whereas values for HBF gilts did not differ from those of the other treatments ( > 0.10). Current results demonstrate that being too thin at the end of gestation (12-15 mm backfat) has a negative impact on mammary development in gilts, whereas having backfats varying from 17 to 26 mm seems to have no detrimental effects on mammogenesis. Backfat thickness in late pregnancy must therefore be considered to achieve optimal sow lactation performance. PMID:27285687

    2015-03-01

    Right-handers tend to associate "good" with the right side of space and "bad" with the left. This implicit association appears to arise from the way people perform actions, more or less fluently, with their right and left hands. Here we tested whether observing manual actions performed with greater or lesser fluency can affect observers' space-valence associations. In two experiments, we assigned one participant (the actor) to perform a bimanual fine motor task while another participant (the observer) watched. Actors were assigned to wear a ski glove on either the right or left hand, which made performing the actions on this side of space disfluent. In Experiment 1, observers stood behind the actors, sharing their spatial perspective. After motor training, both actors and observers tended to associate "good" with the side of the actors' free hand and "bad" with the side of the gloved hand. To determine whether observers' space-valence associations were computed from their own perspectives or the actors', in Experiment 2 we asked the observer to stand face-to-face with the actor, reversing their spatial perspectives. After motor training, both actors and observers associated "good" with the side of space where disfluent actions had occurred from their own egocentric spatial perspectives; if "good" was associated with the actor's right-hand side it was likely to be associated with the observer's left-hand side. Results show that vicarious experiences of motor fluency can shape valence judgments, and that observers spontaneously encode the locations of fluent and disfluent actions in egocentric spatial coordinates.

    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.

Participants were 265 girls in Grades 4 to 7 (M age = 10.71 years) from 5 private primary schools in metropolitan Adelaide, South Australia. Girls completed questionnaire measures of appearance television and magazine exposure, peer appearance conversations, autonomy, appearance schemas, and body dissatisfaction. Appearance media exposure and peer appearance conversations were negatively related to body esteem, and autonomy positively predicted body esteem. Most important, appearance schemas mediated between all sociocultural variables and body dissatisfaction. PMID:17206883

    [Purpose] The purpose of the present study was to examine the effects of progressive body weight supported treadmill forward and backward walking training (PBWSTFBWT), progressive body weight supported treadmill forward walking training (PBWSTFWT), progressive body weight supported treadmill backward walking training (PBWSTBWT), on stroke patients’ affected side lower extremity’s walking ability. [Subjects and Methods] A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the affected side lower extremity’s walking ability, step length of the affected side, stance phase of the affected side, swing phase of the affected side, single support of the affected side, and step time of the affected side were measured using optogait and the symmetry index. [Results] In the within group comparisons, all the three groups showed significant differences between before and after the intervention and in the comparison of the three groups, the PBWSTFBWT group showed more significant differences in all of the assessed items than the other two groups. [Conclusion] In the present study progressive body weight supported treadmill training was performed in an environment in which the subjects were actually walked, and PBWSTFBWT was more effective at efficiently training stroke patients’ affected side lower extremity’s walking ability.

    control are "emotional eating" and "externality", which represent an individual's vulnerability to eat in response to emotional states or external cues, respectively. These questionnaires have been translated into French and validated for the French population. Average data are available for normal weight and obese French men and women. A gender difference is often reported: women, and even young girls, tend to have higher scores than males for most dimensions. These questionnaires have been extensively used in populations without psychiatric disorders, with the only exception of diagnosed eating disorders such as anorexia and bulimia nervosa. The questionnaires have not been used until now in populations with other types of psychiatric disorders, such as schizophrenia or bipolar disease. Their relevance for such populations is now an important question, since last generation pharmaceutical treatments of such psychiatric disorders seem to adversely affect body weight control. It then becomes critical to know whether the psychological dimensions assessed by such questionnaires reflect the action of pharmacological agents that induce weight gain. A research project is now in progress at Sainte-Anne Hospital to investigate many dimensions of the motivation to eat, as assessed by the questionnaires, in psychiatric patients receiving various types of antipsychotic agents. The results of this original study might provide hints about the mechanisms that lead to body weight gain in patients receiving certain types of antipsychotic pharmacological agents and potentially help in preventing or reversing the weight gain associated with such treatments.

    This article discusses women's body image resilience. Body image dissatisfaction is prevalent among girls and women. Girls as young as 6 years old experience negative body image, and there is evidence that women struggle with body concerns throughout the life cycle (Lewis & Cachelin, 2001; Smolak, 2002; Striegel-Moore & Franko, 2002).

    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.

    Our research examined the effects of thin ideal priming on the perception of body image words in participants without an eating disorder. Half of the participants were primed by viewing thin models, and half were primed with gender-neutral shoes. Subsequently, all participants (N=56) completed a Stroop task for three categories of words: neutral (BOOKS), shoe (CLOGS), and body (THIGHS). Lastly, all participants completed a body dissatisfaction questionnaire. We predicted that body dissatisfaction scores would be correlated with the Stroop effect. We found a significant correlation between body dissatisfaction and the body effect of slower color naming times for the body related words compared to the neutral words. Our study demonstrates that body dissatisfaction and a brief priming with thin models results in subsequent differences in performing a Stroop task in a non clinical population of female participants.

    This paper reports the effect of proposed software products features on the satisfaction and dissatisfaction of potential customers of proposed software products. Kano model's functional and dysfunctional technique was used along with Berger et al.'s customer satisfaction coefficients. The result shows that only two features performed the most in influencing the satisfaction and dissatisfaction of would-be customers of the proposed software product. Attractive and one-dimensional features had the highest impact on the satisfaction and dissatisfaction of customers. This result will benefit requirements analysts, developers, designers, projects and sales managers in preparing for proposed products. Additional analysis showed that the Kano model's satisfaction and dissatisfaction scores were highly related to the Park et al.'s average satisfaction coefficient (r=96%), implying that these variables can be used interchangeably or in place of one another to elicit customer satisfaction. Furthermore, average satisfaction coefficients and satisfaction and dissatisfaction indexes were all positively and linearly correlated.

  1. Adolescence and body image.

    Concerns about body image range from a normal desire to look attractive to a pathological concern with thinness or physical perfection. Today, more than ever, adolescents in America are prone to body image distortions and dissatisfaction. The reasons for this are multi-determined and include the influence of the media and cultural expectations, as well as a discrepancy between an adolescent's own physical characteristics and the expectations of his or her social environment. Adolescents with severe body image distortions are vulnerable to developing serious psychiatric disorders that can have life-threatening consequences. Schools can help by providing guidance and information in a time of uncertainty. PMID:12046161

    This study investigated the various stressors encountered by the nursing profession. In particular, the following hypotheses were tested: (1) working conditions of nurses significantly affect perceived risk of injury and illness, work dissatisfaction, work satisfaction, energy state at the end of workday, the effort exerted by the registered nurse (RN), psychosomatic outcomes, and musculoskeletal symptoms (in multiple body regions); (2) both intermediate work effects (i.e., effort, perceived risk of injury/illness, work satisfaction/dissatisfaction, energy state at end of workday) and psychosomatic outcomes significantly affect musculoskeletal outcomes (in multiple body regions); (3) both working conditions and effects significantly affect musculoskeletal outcomes. In a preliminary study conducted on 34 registered nurses, results show that: (1) stressful working conditions affect musculoskeletal outcomes in multiple body regions, and (2) physical maladies such as lower back problems are not only associated with physical factors but also with a complex interaction of working conditions. Further research is warranted to obtain a better understanding of the complex interaction and the synergistic effects of the various nursing working conditions. PMID:12933079

    Coordinated collective motion (CCM) has been recently studied using agent-based simulations by applying three behavioural rules: repulsion, attraction and alignment. But these rules are so similar to the expected group behaviour that it can hardly be labelled emergent. We developed an agent-based model that produces CCM using a set of low-level dyadic interaction rules. The agents change their positions with regard to other agents in order to minimize their own dissatisfaction with their inter-individual distances. To test the emergence of CCM, several simulation experiments were performed. The results show that the agents were able to achieve CCM after a few thousand time steps, and that the bigger the area perceived by them, the more coordinated and cohesive the group motion became. An increased memory span and capacity to remember other agents' identities improved cohesion and coordination. The relationship with biological referents is discussed. PMID:26626359

    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

    Some insect species are capable of producing an enhanced immune response after a first pathogenic encounter, a process called immune priming. However, whether and how such ability is driven by particular diet components (protein/carbohydrate) have not been explored. Such questions are sound given that, in general, immune response is dietary dependent. We have used adults of the house cricket Acheta domesticus L. (Orthoptera: Gryllidae) and exposed them to the bacteria Serratia marcescens. We first addressed whether survival rate after priming and nonpriming treatments is dietary dependent based on access/no access to proteins and carbohydrates. Second, we investigated how these dietary components affected fat reserves, muscle mass, and body weight, three key traits in insect fitness. Thus, we exposed adult house crickets to either a protein or a carbohydrate diet and measured the three traits. After being provided with protein, primed animals survived longer compared to the other diet treatments. Interestingly, this effect was also sex dependent with primed males having a higher survival than primed females when protein was supplemented. For the second experiment, protein-fed animals had more fat, muscle mass, and body weight than carbohydrate-fed animals. Although we are not aware of the immune component underlying immune priming, our results suggest that its energetic demand for its functioning and/or consequent survival requires a higher demand of protein with respect to carbohydrate. Thus, protein shortage can impair key survival-related traits related to immune and energetic condition. Further studies varying nutrient ratios should verify our results. PMID:27037705

  6. Basal Body Structures Differentially Affect Transcription of RpoN- and FliA-Dependent Flagellar Genes in Helicobacter pylori

    2015-01-01

    ABSTRACT Flagellar biogenesis in Helicobacter pylori is regulated by a transcriptional hierarchy governed by three sigma factors, RpoD (σ80), RpoN (σ54), and FliA (σ28), that temporally coordinates gene expression with the assembly of the flagellum. Previous studies showed that loss of flagellar protein export apparatus components inhibits transcription of flagellar genes. The FlgS/FlgR two-component system activates transcription of RpoN-dependent genes though an unknown mechanism. To understand better the extent to which flagellar gene regulation is coupled to flagellar assembly, we disrupted flagellar biogenesis at various points and determined how these mutations affected transcription of RpoN-dependent (flaB and flgE) and FliA-dependent (flaA) genes. The MS ring (encoded by fliF) is one of the earliest flagellar structures assembled. Deletion of fliF resulted in the elimination of RpoN-dependent transcripts and an ∼4-fold decrease in flaA transcript levels. FliH is a cytoplasmic protein that functions with the C ring protein FliN to shuttle substrates to the export apparatus. Deletions of fliH and genes encoding C ring components (fliM and fliY) decreased transcript levels of flaB and flgE but had little or no effect on transcript levels of flaA. Transcript levels of flaB and flgE were elevated in mutants where genes encoding rod proteins (fliE and flgBC) were deleted, while transcript levels of flaA was reduced ∼2-fold in both mutants. We propose that FlgS responds to an assembly checkpoint associated with the export apparatus and that FliH and one or more C ring component assist FlgS in engaging this flagellar structure. IMPORTANCE The mechanisms used by bacteria to couple transcription of flagellar genes with assembly of the flagellum are poorly understood. The results from this study identified components of the H. pylori flagellar basal body that either positively or negatively affect expression of RpoN-dependent flagellar genes. Some of these

    Ingesting the amino acid l-ornithine effectively improves lipid metabolism in humans, although it is unknown whether it affects the activities of autonomic nerves that supply the peripheral organs related to lipid metabolism, such as adipose tissues. Thus, we investigated the effects of l-ornithine ingestion on autonomic nerves that innervate adipose tissues and the feeding behaviors of rats. Intragastric injection of l-ornithine (2.5%) in urethane-anesthetized rats activated sympathetic nerve activity to white adipose tissue (WAT-SNA), and stimulated sympathetic nerve activity to brown adipose tissue (BAT-SNA). In addition, WAT-SNA responses to l-ornithine were abolished in rats with ablated abdominal vagal nerves. l-ornithine ingestion for 9 weeks also significantly reduced rats' body weight, food intake, and abdominal fat weight. Proopiomelanocortin (POMC) levels in the hypothalamus and uncoupling protein 1 (UCP1) levels in brown adipose tissue were significantly increased in rats that ingested 2.5% l-ornithine for 9 weeks. These results suggested that ingested l-ornithine was taken up in the gastrointestinal organs and stimulated afferent vagal nerves and activated the central nervous system. Subsequently, increased hypothalamic POMC activated sympathetic neurotransmission to adipose tissues and accelerated energy expenditure. PMID:25526897

    Precalving feeding level affects dry matter intake, postcalving energy balance, the risk of hepatic lipidosis and metabolic disease, and gene expression in liver and adipose tissue. These coincide with a higher risk of disease postpartum and, very likely, a failure to reach optimum production as well as reproductive targets. Current interpretation of the available evidence suggest that metabolic stressors affect the immune system of transition dairy cows and lead to reduced immunocompetence. The objective of the current study was to investigate the effect of precalving body condition score (BCS) and level of feeding on immunocompetence during the peripartum period. Twenty-three weeks before calving, 78 cows were allocated randomly to 1 of 6 treatment groups (n=13) in a 2 × 3 factorial arrangement: 2 precalving BCS categories (4.0 and 5.0, based on a 10-point scale) and 3 levels of energy intake during the 3 wk preceding calving (75, 100, and 125% of estimated requirements). Blood was sampled precalving and at 1, 2 and 4 wk after calving. Cells were analyzed by flow cytometry and quantitative real-time PCR. The numbers of T helper lymphocytes (CD4+), cytotoxic T lymphocytes (CD8+), natural killer cells (CD335+), and γδ T lymphocytes (WC1+) as well as their activation status [IL-2 receptor (CD25)+ cells] were highly variable between animals, but there was no evident effect of BCS, feeding level, or time. All groups presented with an increase in expression of cytokines in unstimulated blood cells in the week after calving, although this was significant only for IFNG in the BCS 4.0 group. Analysis of in vitro-stimulated cells allowed 2 general observations: (1) cows with high energy intake precalving (125%) had increased cytokine expression precalving, and (2) all cows had increased cytokine expression in the week after calving. The present study provides evidence that prepartum feed management can affect immunocompetence during the transition period. Considering

    The purpose of this study was to assess how carrying a rifle in both hands affects upper body motion and coordination during locomotion. In total, 11 male soldiers walked (1.34 m/s) and ran (2.46 m/s) with a weapon (M4 condition) and without a weapon (NW condition) while kinematic pelvis and trunk data were collected. Two-way ANOVA was used to compare segmental ranges of motion (ROM), pelvis-trunk coordination (continuous relative phase) and coordination variability between gait mode and weapon combinations. Carrying a weapon decreased sagittal plane trunk ROM at both speeds and increased trunk rotation during running. Mean (±SD) transverse plane coordination was more in-phase while carrying a weapon (M4 = 83°±31, NW = 60°±36, p = 0.027) and transverse plane coordination variability decreased (M4 = 23°±3.6, NW = 15°±4.4, p = 0.043). Coordination differences between M4 and NW were similar to differences reported in the literature between individuals with and without back pain. Long-term injury implications due to decreased coordination variability are discussed. STATEMENT OF RELEVANCE: Knowledge of the effects of rifle carriage on pelvis-trunk coordination may provide insight into short-term protective strategies and long-term injury mechanisms. These should be considered in occupations requiring individuals to carry torso loads in combination with holding an object in both hands that restricts arm swing. PMID:21294016

    Background It is unknown whether Whole-Body Hypothermia (WBH) affects pulmonary function. In vitro studies, at relatively low temperatures, suggest that hypothermia may induce significant changes to the surfactant composition. The effect of WBH on surfactant kinetics in newborn infants is unknown. We studied in vivo kinetics of disaturated-phosphatidylcholine (DSPC) in asphyxiated newborns during WBH and in normothermic controls (NTC) with no or mild asphyxia. Both groups presented no clinically apparent lung disease. Methods Twenty-seven term or near term newborns requiring mechanical ventilation were studied (GA 38.6±2.2 wks). Fifteen during WBH and twelve NTC. All infants received an intra-tracheal dose of 13C labelled DSPC and tracheal aspirate were performed. DSPC amount, DSPC half-life (HL) and pool size (PS) were calculated. Results DSPC amount in tracheal aspirates was 0.42 [0.22–0.54] and 0.36 [0.10–0.58] mg/ml in WBH and NTC respectively (p = 0.578). DSPC HL was 24.9 [15.7–52.5] and 25.3 [15.8–59.3] h (p = 0.733) and DSPC PS was 53.2 [29.4–91.6] and 40.2 [29.8–64.6] mg/kg (p = 0.598) in WBH and NTC respectively. Conclusions WBH does not alter DSPC HL and PS in newborn infants with no clinical apparent lung disease. PMID:27070307

    In gender dysphoria (GD), much of the experienced distress results from body dissatisfaction. The current study analyzed the configuration of body satisfaction in trans men and women using network analysis. In total, 485 individuals diagnosed with GD from four European countries, applying for medical treatment, filled out the Body Image Scale for Transsexuals. A six-factor model reflecting different body areas was confirmed via confirmatory factor analysis. A further configuration of body satisfaction was modelled using correlation network analysis techniques in R. Genital dissatisfaction showed limited connection with other body areas in comparison to other subscales. Body characteristics influencing social gender recognition were most centrally involved in body (dis)satisfaction in both natal sexes. In trans women these characteristics were related mostly to voice and hair, whereas in trans men these characteristics were related to muscularity and posture. Focusing on these socially influential body characteristics may provide important targets for transgender healthcare. PMID:27137814

  13. Understanding Customer Dissatisfaction with Underutilized Distributed File Servers

    An important trend in the design of storage subsystems is a move toward direct network attachment. Network-attached storage offers the opportunity to off-load distributed file system functionality from dedicated file server machines and execute many requests directly at the storage devices. For this strategy to lead to better performance, as perceived by users, the response time of distributed operations must improve. In this paper we analyze measurements of an Andrew file system (AFS) server that we recently upgraded in an effort to improve client performance in our laboratory. While the original server's overall utilization was only about 3%, we show how burst loads were sufficiently intense to lead to period of poor response time significant enough to trigger customer dissatisfaction. In particular, we show how, after adjusting for network load and traffic to non-project servers, 50% of the variation in client response time was explained by variation in server central processing unit (CPU) use. That is, clients saw long response times in large part because the server was often over-utilized when it was used at all. Using these measures, we see that off-loading file server work in a network-attached storage architecture has to potential to benefit user response time. Computational power in such a system scales directly with storage capacity, so the slowdown during burst period should be reduced.

    A fully national sample of 1255 people were questioned about their degree of satisfaction with hospital care in New Zealand. Questions covered both public and private hospitals and concerned actual experience of care as well as general attitudes to that care. Almost half the sample (49%) rated public hospital care as "excellent" or "very good", and a similar proportion (48%) assigned those grades to private hospitals. Only 7% of the sample rated public hospital care as "poor" or "very poor" and only 1% rated private hospitals in this way. Major reasons for satisfaction with public hospital care were the high standard of nursing care (41% of sample), the high qualifications of staff (34%) and the availability of appropriate equipment for emergencies (17%). The most common complaints were that hospitals are short-staffed/overworked (15%) and there are long waiting lists (14%). Reasons for satisfaction with private hospital care were no waiting (26%), good standard of care (20%) and good hotel facilities (14%). In general, both public and private hospitals were highly regarded. Dissatisfaction with public hospitals was most evident amongst younger, working people and amongst those in the north and central regions. Dunedin respondents were more satisfied with their hospital care than those in other parts of the country. PMID:3419682

    This article focuses on a study conducted with the purpose of exploring and describing the organisational climate as a cause of job dissatisfaction among nursing staff in selected hospitals within the Mpumalanga Province. The major objectives were to determine what organisational climate encompasses; ascertain which factors related to organisational climate can cause dissatisfaction among nurses; determine whether there is a difference in the way nursing management and the nursing staff perceive the existing organisational climate; and make recommendations for health service managers to improve the organisational climate in order to facilitate greater job satisfaction among the nursing staff. A quantitative approach with an exploratory and descriptive design encompassing the survey method was used. A questionnaire was applied as the data collection instrument and was distributed to 140 respondents. The results indicated that the nursing management and the nursing staff were content with the intrinsic factors of their jobs, but were dissatisfied with the extrinsic factors of the organisational climate. The outcome of this research affirms that there are extrinsic factors within the organisational climate that affect the nursing management and the nursing staff adversely. Recommendations were made to promote job satisfaction in selected public hospitals within the Mpumalanga province. PMID:17310742

    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.

    Although studies on the association of job dissatisfaction with mental health have been conducted in the past, few studies have dealt with the complicated links connecting job stress, job dissatisfaction, and stress-related illness. This study seeks to determine how job dissatisfaction is linked to common mental health issues. This study surveyed 3,172 civil servants (2,233 men and 939 women) in 1998, taking poor mental functioning, fatigue, and sleep disturbance as stress-related mental health problems. We examine how psychosocial risk factors at work and job dissatisfaction are associated independently with poor mental functioning, fatigue, and sleep disturbance after adjustment for other known risk factors, and how job dissatisfaction contributes to change in the degree of association between psychosocial risk factors at work and mental health problems. In general, psychosocial risk factors were independently associated with mental health problems. When adjusted for job dissatisfaction, not only was job satisfaction independently associated with mental health problems but it was also found that the association of psychosocial risk factors with mental health problems declined. Our results suggest that, although longitudinal research is necessary, attitudes toward satisfaction at work can potentially decrease the negative effects of psychosocial risk factors at work on mental health.

    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. PMID:22673451

    Background: There is increasing evidence that children are showing body image issues in recent years. Body image disturbances in childhood must be taken seriously. The thin ideal is becoming more prominent in Asian countries; however, there is little research examining how this issue affects Iranian children. This study explores body weight concerns and associated factors among children in Iranian elementary schools. Methods: This study was conducted in 500 elementary schools. An assessment of body image and antifat attitudes was undertaken using the figure rating scale. In addition, body mass index (BMI) and demographic variables were assessed. Results: Nearly, 27.4% of children were underweight, and 13.3% were obese. There was a significant difference between the mean score of body dissatisfaction (BD) between boys and girls (P < 0.05). There were no differences between BD and education of parents, age, and academic grades. In girls, antifat attitudes were significantly related to BMI. Conclusions: The results of this study demonstrate the paramount importance of undertaking further research in order to identify the predictive factors of body concerns and its consequences among Iranian children. In addition, researchers must plan prevention and educational program for these children. PMID:25709795

    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. PMID:24144298

    Calving body condition score (BCS) is an important determinant of early-lactation dry matter intake, milk yield, and disease incidence. The current study investigated the metabolic and molecular changes induced by the change in BCS. A group of cows of mixed age and breed were managed from the second half of the previous lactation to achieve mean group BCS (10-point scale) that were high (HBCS, 5.5; n=20), medium (MBCS, 4.5; n=18), or low (LBCS, 3.5; n=19). Blood was sampled at wk -4, -3, -2, 1, 3, 5, and 6 relative to parturition to measure biomarkers of energy balance, inflammation, and liver function. Liver was biopsied on wk 1, 3, and 5 relative to parturition, and 10 cows per BCS group were used for transcript profiling via quantitative PCR. Cows in HBCS and MBCS produced more milk and had greater concentrations of nonesterified fatty acids and β-hydroxybutyrate postpartum than LBCS. Peak concentrations of nonesterified fatty acids and β-hydroxybutyrate and greater hepatic triacylglycerol concentrations were recorded in HBCS at wk 3. Consistent with blood biomarkers, HBCS and MBCS had greater expression of genes associated with fatty acid oxidation (CPT1A, ACOX1), ketogenesis (HMGCS2), and hepatokines (FGF21, ANGPTL4), whereas HBCS had the lowest expression of APOB (lipoprotein transport). Greater expression during early lactation of BBOX1 in MBCS and LBCS suggested greater de novo carnitine synthesis. The greater BCS was associated with lower expression of growth hormone/insulin-like growth factor-1 signaling axis genes (GHR1A, IGF1, and IGFALS) and greater expression of gluconeogenic genes. These likely contributed to the higher milk production and greater gluconeogenesis. Despite greater serum haptoglobin around calving, cows in HBCS and MBCS had greater blood albumin. Cows in MBCS, however, had a higher albumin:globulin ratio, probably indicating a less pronounced inflammatory status and better liver function. The marked decrease in expression of NFKB1

    The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 African Black unsexed ostrich chicks were used in the present study in simple randomized design. The results of the present work indicated that initial and final live body weight, body weight gain, feed consumption, feed conversion of ostrich chicks were insignificantly affected by dietary protein level used. Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP. Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level. Body height and tibiotarsus length were not significantly different. In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%). PMID:26623373

    Objective Weight dissatisfaction, defined as discordance between actual and goal weight, may be associated with increased risk for several obesity-related comorbidities. The purpose of the study was to examine the association between weight dissatisfaction and risk of developing type 2 diabetes. Methods This longitudinal study used data from 9,584 adults enrolled in the Aerobics Center Longitudinal Study with an average of 5.1±4.1 years of follow-up. Key variables included multiple measures of measured weight, self-reported goal weight, and incident diabetes. Weight dissatisfaction was defined as being above the median of measured weight minus goal weight. Cox proportional hazards regression estimated hazard ratios (HR) and 95% confidence intervals (95%CI) for diabetes incidence by weight dissatisfaction. Results HRs for time-until-diabetes diagnosis revealed that family history of diabetes (HR=1.46, 95%CI=1.13-1.90), age (HR=1.03, 95%CI=1.02-1.04), and weight dissatisfaction (HR=1.83, 95%CI=1.50-2.25) at baseline were statistically significant predictors. Longitudinally, higher risk was observed in individuals who either stayed dissatisfied (HR=2.98, 95%CI=1.98-4.48) or became dissatisfied (HR=1.51, 95%CI=0.79-2.89), compared to those who either stayed satisfied (HR=1.00, referent) or became satisfied (HR=0.98, 95%CI=0.46-2.10). After additional adjustment for BMI, the elevated HR for those who remained dissatisfied compared to those who remained satisfied persisted (HR=2.85, 95%CI=1.89-4.31). Conclusions Chronic weight dissatisfaction increased type 2 diabetes risk. Weight dissatisfaction, regardless of BMI, represents a potentially important psychophysiological modifier of the relationships between BMI and risk of type 2 diabetes and warrants greater attention in future studies of chronic disease risk.

    Horse riding (HR) is a sport harmonized with rider and horse. HR is renowned as an effective sport for young and old women and men. There is rare study regarding comparison between elite horse riders and amateurs. We aimed to investigate comprehensive ranges of parameters such as change of lactate, heart rate, calorie, VO2max, skeletal muscle mass, body water, body fat, etc between amateurs and professionals to emphasize HR not only as a sport training but also as a therapeutic aspect. We performed 3 experiments for comparing physical fitness, body compositions, lactate value, heart rate and calorie consumption change before and after riding between amateurs and elites. Around 3 yr riding experienced elites are preeminent at balance capability compared to 1 yr riding experienced amateurs. During 18 min horse riding, skeletal muscle mass and body fat were interestingly increased and decreased, respectively. Lactate response was more sensitive in elites rather than amateurs and its recovery was reversely reacted. Exercise intensity estimated from heart rate was significantly higher in elites (P<0.05). The similar pattern of calorie consumption during riding between amateurs and elites was shown. Horse riding possibly induces various physiological (muscle strength, balance, oxidative capability, flexibility, and metabolic control) changes within body and is thus highly recommended as combined exercise for women, children, and aged as therapeutic and leisure sport activity.

    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. PMID:25065119

    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. PMID:26989980

    Our study focuses on the Iberian ibex (Capra pyrenaica) from the Sierra Nevada Natural Space (southern Spain), where sarcoptic mange is an endemic disease and animals are affected by a highly seasonal environment. Our aim was to distinguish between disease and environmental influences on seasonal variation in body weight, hematology, and serum biochemistry in Iberian ibex. We sampled 136 chemically immobilized male ibexes. The single effect of mange influenced hemoglobin, hematocrit, mean corpuscular volume, leukocytes, band neutrophils, monocytes, cholesterol, urea, creatine, and aspartate aminotransferase. Both mange and the period of the year also affected values of mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, neutrophils, glucose, and serum proteins. Scabietic animals showed a marked reduction in body weight (21.4 kg on average), which was more pronounced in winter. These results reveal that 1) infested animals are anemic, 2) secondary infections likely occur, and 3) sarcoptic mange is catabolic. PMID:25380360

    Mosquitoes display biting preferences among different sites of the human body. In addition to height or convection currents, body odour may play a role in the selection of these biting sites. Previous studies have shown that skin emanations are important host-finding cues for mosquitoes. In this study, skin emanations were collected from armpits, hands and feet; the volatile profiles were analysed and tested for their attractiveness to the malaria mosquito Anopheles coluzzii. Skin emanations collected from armpits were less attractive to An. coluzzii compared to hands or/and feet. The difference may have been caused by deodorant residues, which were found in the armpit samples and not in those of hands and feet. In a subsequent experiment, volunteers were asked to avoid using skincare products for five days, and thereafter, no differences in attractiveness of the body parts to mosquitoes were found. The detected deodorant compound isopropyl tetradecanoate inhibited mosquito landings in a repellent bioassay. It is concluded that the volatiles emanated from different body parts induced comparable levels of attraction in mosquitoes, and that skincare products may reduce a person’s attractiveness to mosquitoes.

    An 8-week feeding trial was carried out with juvenile yellow catfish to study the effects of dietary available phosphorus (P) on growth performance, body composition, and hepatic antioxidant property. Six pellet diets were formulated to contain graded available P levels at 0.33, 0.56, 0.81, 1.15, 1.31, and 1.57% of dry matter, respectively. Triplicate tanks with each tank containing 60 juveniles (3.09 ± 0.03 g) were fed one of the six experimental diets for 8 weeks. Specific growth rate, feeding rate, and protein efficiency ratio were significantly higher at 0.81% dietary available P. Efficiency of P utilization distinctly decreased with increasing P level. Body lipid content significantly decreased while body ash and feces P content significantly increased with increasing P level. Quadratic regression analysis indicated that vertebrae P content was maximized at 1.21% dietary available P. Fish fed 1.57% dietary available P had highest activity of hepatic superoxide dismutase and catalase and malonaldehyde content. In conclusion, decreasing dietary available P increased P utilization efficiency and body lipid content while decreased vertebrae P content. Juvenile yellow catfish were subjected to oxidative damage under the condition of high dietary P content (1.57%), and the damage could not be eradicated by their own antioxidant defense system.

    There is increasing interest in understanding what role, if any, sex and sexual orientation play in body dissatisfaction, its correlates to distress, and its relationship to disordered eating. The goals of the present study were to examine: (a) differences in sex and sexual orientation in internalization of societal pressure to modify physical appearance, components of body image dissatisfaction, self-esteem, and eating disorder symptomatology and (b) whether the internalization-eating disorder symptomatology was mediated by the different components of body image dissatisfaction and low self-esteem. The present data support several key trends in the literature: men generally reported less body dissatisfaction, internalization of socio-cultural standards of beauty, drive for thinness, and disordered eating, but a greater drive for muscularity than women; results also indicated that different components of body image dissatisfaction and low self-esteem partially mediated the relationship between internalization and eating disorder symptomatology. Gay men reported significantly more body dissatisfaction, internalization, eating disorder symptomatology, drive for thinness, and drive for muscularity than heterosexual men. Compared to heterosexual women, lesbians reported increased drive for muscularity, lower self-esteem, and lower internalization; however, they did not significantly differ on body dissatisfaction, drive for thinness or disordered eating. Correlation coefficients between body shape dissatisfaction and several aspects of mental distress were significantly larger for gay men than heterosexual men; the same coefficients did not differ between lesbian women and heterosexual women. Results of path analyses indicated that the relationship between internalization and disordered eating differs for gay and heterosexual men but not for lesbian and heterosexual women. These results call attention to lesbians as a generally understudied population. PMID:24348441

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

    This study examined mechanisms of strain crossover within couples and the moderating role of gender. Data were collected at a time of military downsizing from a sample of 1,250 Russian army officers and their spouses. The authors tested a model that incorporated 3 mechanisms for the crossover of marital dissatisfaction among dual-earner couples. The model provided support for 2 suggested crossover mechanisms: direct reactions of crossover and indirect mediated effects through social undermining. Strong evidence was also provided for gender asymmetry in the crossover process. Marital dissatisfaction crossed over from husbands to wives but not vice versa, and social undermining behavior played a role in the process of crossover of marital dissatisfaction for husbands but not for wives.

    Background The objective of the present study was to map candidate loci influencing naturally occurring variation in triacylglycerol (TAG) storage using quantitative complementation procedures in Drosophila melanogaster. Based on our results from Drosophila, we performed a human population-based association study to investigate the effect of natural variation in LAMA5 gene on body composition in humans. Results We identified four candidate genes that contributed to differences in TAG storage between two strains of D. melanogaster, including Laminin A (LanA), which is a member of the α subfamily of laminin chains. We confirmed the effects of this gene using a viable LanA mutant and showed that female flies homozygous for the mutation had significantly lower TAG storage, body weight, and total protein content than control flies. Drosophila LanA is closely related to human LAMA5 gene, which maps to the well-replicated obesity-linkage region on chromosome 20q13.2-q13.3. We tested for association between three common single nucleotide polymorphisms (SNPs) in the human LAMA5 gene and variation in body composition and lipid profile traits in a cohort of unrelated women of European American (EA) and African American (AA) descent. In both ethnic groups, we found that SNP rs659822 was associated with weight (EA: P = 0.008; AA: P = 0.05) and lean mass (EA: P= 0.003; AA: P = 0.03). We also found this SNP to be associated with height (P = 0.01), total fat mass (P = 0.01), and HDL-cholesterol (P = 0.003) but only in EA women. Finally, significant associations of SNP rs944895 with serum TAG levels (P = 0.02) and HDL-cholesterol (P = 0.03) were observed in AA women. Conclusion Our results suggest an evolutionarily conserved role of a member of the laminin gene family in contributing to variation in weight and body composition. PMID:18694491

    Rapid body mass loss (RBML) before competition was found to decrease hemoglobin mass (Hbmass ) in elite boxers. This study aimed to investigate the underlying mechanisms of this observation. Fourteen well-trained combat athletes who reduced body mass before competitions (weight loss group, WLG) and 14 combat athletes who did not practice RBML (control group, CON) were tested during an ordinary training period (t-1), 1-2 days before an official competition (after 5-7 days RBML in WLG, t-2), and after a post-competition period (t-3). In WLG, body mass (-5.5%, range: 2.9-6.8 kg) and Hbmass (-4.1%) were significantly (P < 0.001) reduced after RBML and were still decreased by 1.6% (P < 0.05) and 2.6% (P < 0.001) at t-3 compared with t-1. After RBML, erythropoietin, reticulocytes, haptoglobin, triiodothyronine (FT3 ), and free androgen index (FAI) were decreased compared with t-1 and t-3. An increase occurred in ferritin and bilirubin. Peak treadmill-running performance and VO2peak did not change significantly, but performance at 4-mmol lactate threshold was higher after RBML (P < 0.05). In CON, no significant changes were found in any parameter. Apparently, the significant decrease in Hbmass after RBML in combat athletes was caused by impaired erythropoiesis and increased hemolysis without significant impact on aerobic performance capacity.

    Introduced American Bullfrogs (Rana catesbeiana) have established breeding populations in several provinces in China since their introduction in 1959. Although Bullfrogs are viewed as a potentially important predator of Chinese native anurans, their impacts in the field are difficult to quantify. We used two experiments to examine factors likely to mediate Bullfrog predation on native anurans. First, we examined effects of Bullfrog size and sex on daily consumption of a common Chinese native (Rana limnocharis). Second, we examined whether Bullfrogs consumed similar proportions of four Chinese natives: Black-Spotted Pond Frog (Rana nigromaculata), Green Pond Frog (Rana plancyi plancyi), Rice Frog (R. limnocharis), and Zhoushan Toad (Bufo bufo gargarizans). We found that larger Rana catesbeiana consumed more R. limnocharis per day than did smaller R. catesbeiana, and that daily consumption of R. limnocharis was positively related to R. catesbeiana body size. When provided with adults of four anurans that differed significantly in body size, R. catesbeiana consumed more individuals of the smallest species (R. limnocharis). However, when provided with similarly sized juveniles of the same four species, R. catesbeiana did not consume any species more than expected by chance. Our results suggest that body size plays an important role in the predatory interactions between R. catesbeiana and Chinese native anurans and that, other things being equal, smaller species and individuals are at greater risk of predation by R. catesbeiana.

    This study examined whether the association between adolescent weight status and body image varies by social engagement. A nationally representative sample of 6,909 students in grades 6 to 10 completed the 2006 HBSC survey. Separate linear regressions for boys and girls, controlling for age, race/ethnicity and socioeconomic status, were conducted with an interaction term (weight status x social engagement). Adolescents’ overweight/obese status was related to body dissatisfaction. Social engagement moderated the relationship between weight status and body image for girls but not for boys. Overweight/obese boys had more body dissatisfaction compared to their normal/underweight peers, regardless of their social engagement. However, overweight/obese girls with more social engagement were more likely to have body satisfaction compared to overweight/obese girls with less social engagement. Encouraging adolescent girls to develop healthy relationships with peers may prevent them from developing body dissatisfaction. PMID:22325852

    This study examined whether rural adolescents would report gender and ethnic differences in body image similar to those that have been observed in urban samples. Data were analyzed for 384 rural adolescents (57% African American, 43% Caucasian, mean age 13 years) to determine gender and ethnic differences in body dissatisfaction, body size discrepancy, and current and ideal figure ratings. Females wanted to be smaller and reported more body dissatisfaction than did males. Caucasian females reported the most body dissatisfaction. African Americans reported larger current and ideal figure ratings than did Caucasians. African Americans preferred larger opposite sex figures than did Caucasians. Both African American and Caucasian males selected a larger female figure as ideal than was selected by females. Results demonstrated that gender and ethnic differences exist in body image for rural adolescents. This frequently overlooked population may benefit from further study. Implications of findings and limitations of the study are also discussed. PMID:18089257

    2013-01-01

    Background Mental health is interconnected with somatic health and can manifest itself in biological processes. Life dissatisfaction is an indicator of subjective well-being, but information on its biological correlates is scarce. The aim of this study was to investigate the biological correlates along with other health-related factors of long-term life dissatisfaction in a population-based sample. Methods As part of the Kuopio Depression Study, health questionnaires were sent to a randomly selected population-based sample in 1998, 1999, and 2001. In 2005, among a clinically studied sub-sample (n = 305), the 7-year long-term life dissatisfaction burden was assessed by summing life satisfaction scores from previous health questionnaires. Several sociodemographic, health, health behavior, and biological factors were investigated in respect to their associations to categorized (low and high) and continuous (linear regression) life satisfaction burden score (higher values indicating dissatisfaction). Results In the final linear regression model long-term life dissatisfaction burden was significantly associated with poor social support (B = 0.138; p < 0.001), marital status (i.e. living alone) (B = 0.049; p = 0.019), current smoking (B = 0.087; p < 0.001), poor sleep (B = 0.052; p = 0.001), use of statins (B = −0.052; p = 0.002) and lower serum adiponectin level (B = −0.001; p = 0.039) whereas association of metabolic syndrome was marginally nonsignificant (B = 0.029; p = 0.055). Conclusion Long-term life dissatisfaction is associated with adverse health, health behavioral, and social factors, as well as with a decreased anti-inflammatory buffer capacity, all indicating close relationships between subjective well-being and somatic morbidity.

  10. Daytime pattern of post-exercise protein intake affects whole-body protein turnover in resistance-trained males

    PubMed Central

    2012-01-01

    Background The pattern of protein intake following exercise may impact whole-body protein turnover and net protein retention. We determined the effects of different protein feeding strategies on protein metabolism in resistance-trained young men. Methods Participants were randomly assigned to ingest either 80g of whey protein as 8x10g every 1.5h (PULSE; n=8), 4x20g every 3h (intermediate, INT; n=7), or 2x40g every 6h (BOLUS; n=8) after an acute bout of bilateral knee extension exercise (4x10 repetitions at 80% maximal strength). Whole-body protein turnover (Q), synthesis (S), breakdown (B), and net balance (NB) were measured throughout 12h of recovery by a bolus ingestion of [15N]glycine with urinary [15N]ammonia enrichment as the collected end-product. Results PULSE Q rates were greater than BOLUS (~19%, P<0.05) with a trend towards being greater than INT (~9%, P=0.08). Rates of S were 32% and 19% greater and rates of B were 51% and 57% greater for PULSE as compared to INT and BOLUS, respectively (P<0.05), with no difference between INT and BOLUS. There were no statistical differences in NB between groups (P=0.23); however, magnitude-based inferential statistics revealed likely small (mean effect±90%CI; 0.59±0.87) and moderate (0.80±0.91) increases in NB for PULSE and INT compared to BOLUS and possible small increase (0.42±1.00) for INT vs. PULSE. Conclusion We conclude that the pattern of ingested protein, and not only the total daily amount, can impact whole-body protein metabolism. Individuals aiming to maximize NB would likely benefit from repeated ingestion of moderate amounts of protein (~20g) at regular intervals (~3h) throughout the day. PMID:23067428

  11. Ablation of the GNB3 gene in mice does not affect body weight, metabolism or blood pressure, but causes bradycardia

    G protein β3 (Gβ3) is an isoform of heterotrimeric G protein β subunits involved in transducing G protein coupled receptor (GPCR) signaling. Polymorphisms in Gβ3 (GNB3) are associated with many human disorders (e.g. hypertension, diabetes and obesity) but the role of GNB3 in these pathogeneses remains unclear. Here, Gβ3-null mice (GNB3−/−) were characterized to determine how Gβ3 functions to regulate blood pressure, body weight and metabolism. We found Gβ3 expression restricted to limited types of tissues, including the retina, several regions of brain and heart ventricles. Gβ3-deficient mice were normal as judged by body weight gain by age or by feeding with high-fat diet (HFD); glucose tolerance and insulin sensitivity; baseline blood pressure and angiotensin II infusion-induced hypertension. During tail-cuff blood pressure measurements, however, Gβ3-null mice had slower heart rates (~450 vs ~500 beats/min). This bradycardia was not observed in isolated and perfused Gβ3-null mouse hearts. Moreover, mouse hearts isolated from GNB3−/− and controls responded equivalently to muscarinic receptor- and β-adrenergic receptor-stimulated bradycardia and tachycardia, respectively. Since no difference was seen in isolated hearts, Gβ3 is unlikely to be involved directly in the GPCR signaling activity that controls heart pacemaker activity. These results demonstrate that although Gβ3 appears dispensable in mice for regulation of blood pressure, body weight and metabolic features associated with obesity and diabetes, Gβ3 may regulate heart rate.

    Recent evidence suggests that fructose consumption is associated with weight gain, fat deposition and impaired cognitive function. However it is unclear whether the detrimental effects are caused by fructose itself or by the concurrent increase in overall energy intake. In the present study we examine the impact of a fructose diet relative to an isocaloric glucose diet in the absence of overfeeding, using a mouse model that mimics fructose intake in the top percentile of the USA population (18% energy). Following 77 days of supplementation, changes in body weight (BW), body fat, physical activity, cognitive performance and adult hippocampal neurogenesis were assessed. Despite the fact that no differences in calorie intake were observed between groups, the fructose animals displayed significantly increased BW, liver mass and fat mass in comparison to the glucose group. This was further accompanied by a significant reduction in physical activity in the fructose animals. Conversely, no differences were detected in hippocampal neurogenesis and cognitive/motor performance as measured by object recognition, fear conditioning and rotorod tasks. The present study suggests that fructose per se, in the absence of excess energy intake, increases fat deposition and BW potentially by reducing physical activity, without impacting hippocampal neurogenesis or cognitive function.

    Ratings of perceived exertion (RPE) are routinely used to monitor, assess, and prescribe aerobic exercise. Heart rate (HR) is another measure used to evaluate exercise intensity. Additionally, affective responses to aerobic exercise have been studied and seem to be influenced by the intensity of the exercise. The perceptual, HR, and affective responses to resistance exercise have not been effectively established. The purpose of this study was to examine whether differences in affect, RPE, and HR exist among college-aged women (n = 31) performing three different modes of resistance training: concentric (CE), eccentric (EE), and traditional concentric/eccentric (TE) performed at varying resistances. The women were asked to complete four sessions of resistance training on variable resistance machines: chest press, seated row, overhead press, and biceps curl. The first session was used to establish the 10-repetition maximum (RM) load for each station. Subsequent sessions involved the execution of training in one of the three test conditions: CE, EE, or TE. The participants performed three sets of each lift at 80% 10-RM, 100% 10-RM, and 120% 10-RM. The data revealed lower RPE during EE than the other test conditions. Similarly, EE elicited more mild HR response than either CE or TE. This finding is potentially important for the establishment of training programs, especially for those individuals recovering from an illness, who had been previously sedentary, and who are involved in rehabilitation of an injury.

    Purpose The increase in tablet usage allows people to perform computer work in non-traditional office environments. The aim of this study was to assess the effects of changes in tablet keyboard design on postures of the upper extremities and neck, discomfort, and usability under different usage positions during prolonged touch-typing. Methods Eighteen healthy participants familiar with touch-screen devices were randomized into three usage positions (desk, lap, and bed) and completed six, 60-minute typing sessions using three virtual keyboard designs (standard, wide, split). Electrogoniometers continuously measured the postures of the wrists, elbow, and neck. Body discomfort and system usability were evaluated by questionnaires before and immediately after each typing session. Results Separate linear mixed effects models on various postural measures and subjective ratings are conducted with usage position as the between-subject factors, keyboard design and typing duration as the with-in subject factors were conducted. Using the tablet in bed led to more extended wrists but a more natural elbow flexion than the desk position. The angled split virtual keyboard significantly reduced the extent of wrist ulnar deviation than the keyboard with either standard or wide design. However, little difference was observed across the usage position and keyboard design. When the postural data were compared between the middle and end of typing sessions, the wrists, elbow, and neck all exhibited a substantially increased range of joint movements (13% to 38%). The discomfort rating also increased significantly over time in every upper body region investigated. Additionally, the split keyboard design received a higher usability rating in the bed position, whereas participants had more satisfactory experience while using the wide keyboard in the traditional desk setting. Conclusions Prolonged use of tablets in non-traditional office environments may result in awkward postures in the

    Body image dissatisfaction and disordered eating attitudes and behaviors are pervasive problems in Western society, particularly for females. The female "thin-ideal" is a potent contributor to the growing discontent with the female body and research has shown that even females who are normal or underweight, perceive themselves as overweight. The goal of the current study was to examine correlates of body image satisfaction and the perception of the female body. One hundred and sixty six female undergraduates (Mean Age=21.40 years) completed self-report measures pertaining to disordered eating (EAT-26) and body dissatisfaction (BIQ and ABS). Body image perception and satisfaction were measured using ratings of female bodies on a weight perception scale (PFRS). Overall, disordered eating was related to a lower ideal body size and greater body dissatisfaction. In support of previous research, the most common ideal female body had a BMI categorized as underweight. Although females in the current sample reported an ideal that was smaller than their current size, participants underestimated their current body size, which, given the amount of dieting and weight pressure in present Western society, seems counterintuitive. It is possible that thin ideal portrayed in the media is increasingly different from and at odds with the average female body. PMID:25955887

    2014-01-01

    Social comparison (i.e., body, eating, exercise) and body surveillance were tested as mediators of the thin-ideal internalization-body dissatisfaction relationship in the context of an elaborated sociocultural model of disordered eating. Participants were 219 college women who completed two questionnaire sessions 3 months apart. The cross-sectional elaborated sociocultural model (i.e., including social comparison and body surveillance as mediators of the thin-ideal internalization-body dissatisfaction relation) provided a good fit to the data, and the total indirect effect from thin-ideal internalization to body dissatisfaction through the mediators was significant. Social comparison emerged as a significant specific mediator while body surveillance did not. The mediation model did not hold prospectively; however, social comparison accounted for unique variance in body dissatisfaction and disordered eating 3 months later. Results suggest that thin-ideal internalization may not be “automatically” associated with body dissatisfaction and that it may be especially important to target comparison in prevention and intervention efforts.

    2008-01-01

    The period following the withdrawal of parental care has been highlighted as a key developmental period for juveniles. One reason for this is that juveniles cannot forage as competently as adults, potentially placing them at greater risk from environmentally-induced changes in food availability. However, no study has examined this topic. Using a long-term dataset on red foxes (Vulpes vulpes), we examined (i) dietary changes that occurred in the one-month period following the attainment of nutritional independence, (ii) diet composition in relation to climatic variation, and (iii) the effect of climatic variation on subsequent full-grown mass. Diet at nutritional independence contained increased quantities of easy-to-catch food items (earthworms and insects) when compared with pre-independence. Interannual variation in the volume of rainfall at nutritional independence was positively correlated to the proportion of earthworms in cub diet. Pre-independence cub mass and rainfall immediately following nutritional independence explained a significant proportion of variance in full-grown mass, with environmental variation affecting full-grown mass of the entire cohorts. Thus, weather-mediated availability of easy-to-catch food items at a key developmental stage has lifelong implications for the development of juvenile foxes by affecting full-grown mass, which in turn appears to be an important component of individual reproductive potential.

    2013-03-01

    For over a century, studies on body fat (BF) in decompression sickness and venous gas embolism of divers have been inconsistent. A major problem is that age, BF, and maximal oxygen consumption (Vo2max) show high multicollinearity. Using the Bühlmann model with eight parallel compartments, preceded by a blood compartment in series, nitrogen tensions and loads were calculated with a 40 min/3.1 bar (absolute) profile. Compared with Haldanian models, the new model showed a substantial delay in N2 uptake and (especially) release. One hour after surfacing, an increase of 14-28% in BF resulted in a whole body increase of the N2 load of 51%, but in only 15% in the blood compartment. This would result in an increase in the bubble grade of only 0.01 Kisman-Masurel (KM) units at the scale near KM = I-. This outcome was tested indirectly by a dry dive simulation (air breathing) with 53 male divers with a small range in age and Vo2max to suppress multicollinearity. BF was determined with the four-skinfold method. Precordial Doppler bubble grades determined at 40, 80, 120, and 160 min after surfacing were used to calculate the Kisman Integrated Severity Score and were also transformed to the logarithm of the number of bubbles/cm(2) (logB). The highest of the four scores yielded logB = -1.78, equivalent to KM = I-. All statistical outcomes of partial correlations with BF were nonsignificant. These results support the model outcomes. Although this and our previous study suggest that BF does not influence venous gas embolism (Schellart NAM, van Rees Vellinga TP, van Dijk FH, Sterk W. Aviat Space Environ Med 83: 951-957, 2012), more studies with different profiles under various conditions are needed to establish whether BF remains (together with age and Vo2max) a basic physical characteristic or will become less important for the medical examination and for risk assessment.

It was interest of the provincial medical board's ethical committee to acquire information about physician's work-related stress and dissatisfaction. The research group was committed to define the indicators of dissatisfaction and work-related stressors. Focus groups were carried out, 21 stressful experience's indicators were identified; we developed an online questionnaire to assess the amount of perceived stress relating to each indicator at work (3070 physicians were contacted by e-mail); quantitative and qualitative data analysis were carried out. The grounded theory perspective was applied in order to assure the most reliable procedure to investigate the concepts' structure of “work-related stress.” We tested the five dimensions' model of the stressful experience with a confirmatory factor analysis: Personal Costs; Decline in Public Image and Role Uncertainty; Physician's Responsibility toward hopelessly ill Patients; Relationship with Staff and Colleagues; Bureaucracy. We split the sample according to attachment style (secure and insecure -anxious and avoidant-). Results show the complex representation of physicians' dissatisfaction at work also with references to the variable of individual difference of attachment security/insecurity. The discriminant validity of the scale was tested. The original contribution of this paper lies on the one hand in the qualitative in depth inductive analysis of physicians' dissatisfaction starting from physicians' perception, on the other hand, it represents the first attempt to analyze the physicians' dissatisfaction

    PLA2 enzyme hydrolyzes arachidonic acid, and other polyunsaturated fatty acids, from the sn-2 position to release free arachidonic acid and a lysophospholipid. Previous studies reported that the PLA2 in invertebrate organisms participates in lipid signaling molecules like arachidonic acid release in immune-associated tissues like hemocytes and fat bodies. In the present study, we cloned the BmPLA2 gene from fat body tissue of silkworm Bombyx mori, which has a total sequence of 1.031 kb with a 31.90 kDa protein. In silico results of BmPLA2 indicated that the protein has a putative WD40 conserved domain and its phylogeny tree clustered with Danaus plexippus species. We investigated the transcriptional expression in development stages and tissues. The highest expression of BmPLA2 was screened in fat body among the studied tissues of third day fifth instar larva, with a high expression on third day fifth instar larva followed by a depression of expression in the wandering stage of the fifth instar larva. The expression of BmPLA2 in female pupa was higher than that of male pupa. Our RNAi-mediated gene silencing results showed highest reduction of BmPLA2 expression in post-24 h followed by post-48 and post-72 h. The BmPLA2-RNAi larvae and pupa could be characterized by pharate adult lethality and underdevelopment. The phenotypic characters of fat body cells in RNAi-induced larva implied that BmPLA2 affects the metabolic functions of fat body tissue in silkworm Bombyx mori. PMID:25409652

    [Purpose] Previous studies have shown that stroke is associated with increased arterial stiffness that can be diminished by a program of physical activity. A novel exercise intervention, whole-body vibration (WBV), is reported to significantly improve arterial stiffness in healthy men and older sedentary adults. However, little is known about its efficacy in reducing arterial stiffness in chronic stroke. [Subjects and Methods] Six participants with chronic stroke were randomly assigned to 4 weeks of WBV training or control followed by cross-over after a 2-week washout period. WBV intervention consisted of 3 sessions of 5 min intermittent WBV per week for 4 weeks. Arterial stiffness (carotid arterial stiffness, pulse wave velocity [PWV], pulse and wave analysis [PWA]) were measured before/after each intervention. [Results] No significant improvements were reported with respect to carotid arterial stiffness, PWV, and PWA between WBV and control. However, carotid arterial stiffness showed a decrease over time following WBV compared to control, but this was not significant. [Conclusion] Three days/week for 4 weeks of WBV seems too short to elicit appropriate changes in arterial stiffness in chronic stroke. However, no adverse effects were reported, indicating that WBV is a safe and acceptable exercise modality for people with chronic stroke. PMID:27134400

    OBJECTIVE To examine whether demographic, socioeconomic conditions, oral health subjectivity and characterization of dental care are associated with users' dissatisfaction with such are. METHODS Cross-sectional study of 781 people who required dental care in Montes Claros, MG, Southeastern Brazil, in 2012, a city with of medium-sized population situated in the North of Minas Gerais. Household interviews were conducted to assess the users' dissatisfaction with dental care (dependent variable), demographic, socioeconomic conditions, oral health subjectivity and characterization of dental care (independent variables). Sample calculation was used for the finite population, with estimates made for proportions of dissatisfaction in 50.0% of the population, a 5.0% error margin, a non-response rate of 5.0% and a 2.0% design effect. Logistic regression was used, and the odds ratio was calculated with a 5% significance level and 95% confidence intervals. RESULTS Of the interviewed individuals, 9.0% (7.9%, with correction for design effect) were dissatisfied with the care provided. These were associated with lower educational level; negative self-assessment of oral health; perception that the care provider was unable to give dental care; negative evaluation of the way the patient was treated, the cleanliness of the rooms, based on the examination rooms and the toilets, and the size of the waiting and examination rooms. CONCLUSIONS The rate of dissatisfaction with dental care was low. This dissatisfaction was associated with socioeconomic conditions, subjectivity of oral health, skill of the health professionals relating to the professional-patient relationship and facility infrastructure. Educational interventions are suggested that aim at improving the quality of care among professionals by responsible agencies as is improving the infrastructure of the care units. PMID:26270017

    Purpose Subjective measures of success after urethroplasty have become increasingly valuable in postoperative monitoring. We examined patient reported satisfaction following anterior urethroplasty using objective measures as a proxy for success. Materials and Methods Men 18 years old or older with urethral strictures undergoing urethroplasty were prospectively enrolled in a longitudinal, multi-institutional urethroplasty outcomes database. Preoperative and postoperative assessment included questionnaires to assess lower urinary tract symptoms, pain, satisfaction and sexual health. Analyses controlling for stricture recurrence (defined as the inability to traverse the reconstructed urethra with a flexible cystoscope) were performed to determine independent predictors of dissatisfaction. Results At a mean followup of 14 months we found a high 89.4% rate of overall postoperative satisfaction in 433 patients and a high 82.8% rate in those who would have chosen the operation again. Men with cystoscopic recurrence were more likely to report dissatisfaction (OR 4.96, 95% CI 2.07–11.90) and men reporting dissatisfaction had significantly worse uroflowmetry measures (each p <0.02). When controlling for recurrence, multivariate analysis revealed that urethra and bladder pain (OR 1.71, 95% CI 1.05–2.77 and OR 2.74, 95% CI 1.12–6.69, respectively), a postoperative decrease in sexual activity (OR 4.36, 95% CI 2.07–11.90) and persistent lower urinary tract symptoms (eg straining to urinate OR 3.23, 1.74-6.01) were independent predictors of dissatisfaction. Conclusions Overall satisfaction after anterior urethroplasty is high and traditional measures of surgical success strongly correlate with satisfaction. However, independently of the anatomical appearance of the reconstructed urethra, postoperative pain, sexual dysfunction and persistent lower urinary tract symptoms were predictors of patient dissatisfaction.

    Obesity-related inflammation may have a causal role in the development of diabetes and insulin resistance, and studies using animal models of chronic experimental endotoxemia have shown the link. However, many studies use only males, and much less is known about the role of obesity-related inflammation in females. Therefore, we addressed how experimentally induced chronic inflammation affects body mass, energy intake, and glucose metabolism in female rats. Adult female Sprague Dawley rats were instrumented with slow release pellets that delivered a constant daily dose of 53 or 207 μg of lipopolysaccharide (LPS) per rat for 60 days. Control rats were instrumented with vehicle pellets. Due to inflammatory nature of high-fat diet (HFD) half of the rats received HFD (60% of calories from lard), while the other half remained on control diet to detect possible interactions between two modes of induced inflammation. Our results showed that chronic LPS administration increased female rat body mass and calorie intake in a dose-dependent manner, and that HFD further exacerbated these effects. Despite these effects, no effects of LPS and HFD were evident on female rat glucose metabolism. Only LPS elevated expression of inflammatory markers in the hypothalamus. To conclude, female rats respond to experimentally induced chronic inflammation by increasing body mass, but do not develop glucose intolerance in the given period of time. PMID:26537342

    Skin rubdown using a dry towel (SRDT) to scrub the whole body is a traditional therapy for health promotion. To investigate its mechanism, 24 healthy male volunteers were studied. Body temperature, pulse rate, red blood cells (RBCs), serum levels of catecholamines and cortisol, blood gases (PO(2), sO(2), PCO(2) and pH), lactate and glucose, and the ratio and number of white blood cells (WBCs) were assessed before and after SRDT. After SRDT, pulse rate and body temperature were increased. PO(2), sO(2) and pH were also increased and there was no Rouleaux formation by RBCs. Lactate level tended to increase, whereas that of glucose did not. Adrenaline and noradrenaline levels increased, indicating sympathetic nerve (SN) dominance with increase in granulocytes. WBC number and ratio were divided into two groups according to granulocyte ratio (≤ or < 60%) before SRDT: a normal group and a SN group. Only in the SN group did the granulocyte ratio decrease and the lymphocyte ratio and number increase after SRDT. It is suggested that SRDT is a mild aerobic, systemic exercise that might affect the immune system via the autonomic nervous system. PMID:22975635

    This study examines the relationship between attributional style and destructive responses to job dissatisfaction among internal migrant workers in mainland China. Contrary to previous studies conducted in the West, we found that internality of bad events was negatively related to destructive responses to job dissatisfaction. Stability and globality were positively related to destructive responses to job dissatisfaction. We suggest that the concept of interdependent self-construal may explain the unique positive meaning of internality of bad events among Chinese migrant workers. The practical significance of the findings is discussed. PMID:25750811

    Job dissatisfaction among nurses contributes to costly labor disputes, turnover, and risk to patients. Examining survey data from 95,499 nurses, we found much higher job dissatisfaction and burnout among nurses who were directly caring for patients in hospitals and nursing homes than among nurses working in other jobs or settings, such as the pharmaceutical industry. Strikingly, nurses are particularly dissatisfied with their health benefits, which highlights the need for a benefits review to make nurses’ benefits more comparable to those of other white-collar employees. Patient satisfaction levels are lower in hospitals with more nurses who are dissatisfied or burned out—a finding that signals problems with quality of care. Improving nurses’ working conditions may improve both nurses’ and patients’ satisfaction as well as the quality of care. PMID:21289340

    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

    Multiple Sclerosis (MS) is an autoimmune inflammatory disease of the central nervous system (CNS) which affects over 2.5 million people worldwide. Although MS has been extensively studied, many challenges still remain in regards to treatment, diagnosis, and prognosis. Typically, prognosis and individual responses to treatment are evaluated by clinical tests such the expanded disability status scale (EDSS), magnetic resonance imaging (MRI), and presence of oligoclonal bands (OCB) in the cerebrospinal fluid (CSF). However, none of these measures correlate strongly with treatment efficacy or disease progression across heterogeneous patient populations and subtypes of MS. Numerous studies over the past decades have attempted to identify sensitive and specific biomarkers for diagnosis, prognosis, and treatment efficacy of MS. The objective of this article is to review and discuss the current literature on body fluid biomarkers in MS, including research on potential biomarker candidates in the areas of microRNA, messenger RNA, lipids, and proteins.

    The whole-body transcriptome of trout alevins was characterised to investigate the effects of long-term feeding of rainbow trout broodstock females a diet free of fishmeal and fish oil on the metabolic capacities of progeny. Effects were studied before first feeding and after 3 weeks of feeding diets containing different proportions of marine and plant ingredients. Feeding alevins plant-based diets resulted in lower fish body weight, irrespective of maternal nutritional history. No differences in whole-body lipids were found between treatments, and the tissue fatty acid profile strongly reflected that of the respective broodstock or first-feeding diets. We showed that the maternal diet history did not significantly affect expressions of any genes before the first feeding. Interestingly, we found an effect of maternal nutritional history on gene expression in alevins after 3 weeks of feeding. The major differences in the transcriptome of alevins from plant-based diet-fed females compared with those from commercial-fed females were as follows: (i) down-regulation of genes involved in muscle growth/contraction and (ii) up-regulation of genes involved in carbohydrate and energy metabolism related to the delay in growth/development observed with plant-based diets. Our findings also showed an effect of the first-feeding diets, irrespective of maternal nutritional history. Specifically, the introduction of plant ingredients resulted in the up-regulation of genes involved in amino acid/protein and cholesterol metabolism and in differences in the expressions of genes related to carbohydrate metabolism. Information gained through this study opens up avenues for further reduction of marine ingredients in trout diets, including the whole rearing cycle. PMID:27112276

    Dietary protein digestion and amino acid absorption kinetics determine the post-prandial muscle protein synthetic response. Body position may affect gastrointestinal function and modulate the post-prandial rise in plasma amino acid availability. We aimed to assess the impact of body position on gastric emptying rate and the post-prandial rise in plasma amino acid concentrations following ingestion of a single, meal-like amount of protein. In a randomized, cross-over design, eight healthy males (25 ± 2 years, 23.9 ± 0.8 kg·m−2) ingested 22 g protein and 1.5 g paracetamol (acetaminophen) in an upright seated position (control) and in a −20° head-down tilted position (inversion). Blood samples were collected during a 240-min post-prandial period and analyzed for paracetamol and plasma amino acid concentrations to assess gastric emptying rate and post-prandial amino acid availability, respectively. Peak plasma leucine concentrations were lower in the inversion compared with the control treatment (177 ± 15 vs. 236 ± 15 mmol·L−1, p < 0.05), which was accompanied by a lower plasma essential amino acid (EAA) response over 240 min (31,956 ± 6441 vs. 50,351 ± 4015 AU; p < 0.05). Peak plasma paracetamol concentrations were lower in the inversion vs. control treatment (5.8 ± 1.1 vs. 10.0 ± 0.6 mg·L−1, p < 0.05). Gastric emptying rate and post-prandial plasma amino acid availability are significantly decreased after protein ingestion in a head-down tilted position. Therefore, upright body positioning should be considered when aiming to augment post-prandial muscle protein accretion in both health and disease. PMID:27089362

    Most insects from temperate areas enter diapause ahead of winter. Species diapausing in a feeding stage and accumulating metabolic reserves during permissive pre-wintering conditions are expected to enter diapause shortly before the onset of winter. In contrast, species diapausing in a non-feeding stage are expected to lower their metabolism as soon as possible to avoid excessive consumption of metabolic reserves. The solitary bee Osmia lignaria winters as a non-feeding adult within its cocoon, but previous studies show important weight losses and increased winter mortality in populations pre-wintered for extended periods. We measured respiration rates to assess diapause initiation and maintenance during pre-wintering, and tested whether timing of adult eclosion affected fitness by measuring fat body depletion, winter mortality and post-winter longevity. We worked with different cohorts of a population reared under natural conditions, and manipulated pre-wintering duration in a population reared under artificial conditions. In agreement with our expectation, O. lignaria lower their metabolic rates within a few days of adult eclosion, but nonetheless suffer strong weight loss during pre-wintering. Early developing individuals suffer greater weight loss and fat body depletion, and have short post-winter longevity. Although, we found no differences in winter mortality among treatments, our results indicate that increased mortality may occur in years with late winter arrivals. We discuss fundamental ecophysiological differences between adult and prepupal diapause within the Megachilidae, and hypothesize that species wintering as adults will be more negatively affected by a situation of extended summers under a scenario of global warming.

    First sexual intercourse is often viewed as a rite of passage to adulthood. While one's initial coital experience may lead to affirmation of self-identity, it is disappointing for many, resulting in feelings of guilt and shame. If guilt feelings do emerge, the likelihood of future sexual dissatisfaction is greatly increased. In particular, women with high levels of sexual guilt tend to perceive less sexual arousal, resulting in less enjoyment from their sexual encounters. The purposes of this investigation were to identify those factors correlated with feeling guilty about first sexual intercourse and to examine the influence of guilt about first intercourse on current sexual satisfaction. An anonymous questionnaire was administered to never-married college women, with the subsample for this investigation consisting of 570 women. Significant variables correlated with guilt at first sexual intercourse include uncommunicative mother and father figures, overstrict father figure, uncomfortableness with sexuality, physiological and psychological sexual dissatisfaction with first intercourse, guilt feelings about current intercourse, and psychological sexual dissatisfaction. These findings have substantial implications for sex researchers, sex therapists, family therapists, and sexuality educators who wish to promote healthy sexuality, through both attitudes and behavior.

The research is of a qualitative nature and the data-collecting medium was semistructured interviews with 19 workers of three Caps in Fortaleza, in the Northern Brazilian State of Ceará. The treatment of the empirical material was based upon the analysis of content with an emphasis on the thematic bias. The results revealed the determinants of (dis)satisfaction present in the daily routine of these workers. The relationships established with the users were singled out as the main source of satisfaction, whereas the work and wage conditions were the main motives for dissatisfaction. In addition to these aspects, consequences of (dis)satisfaction at work in the private, social and organizational field of the workers' life in the Caps were revealed, mainly in physical and mental health. Lastly, they emphasized the urgent need for implementation - on the part of public administration - of strategies that seek to reduce the precariousness of healthcare work, especially in mental health, with a view to mitigating damages potentially caused by such work.

    A comprehensive method for the analysis of 11 target pharmaceuticals representing multiple commonly used therapeutic classes was developed for biological tissues (fish), reclaimed water, and the surface water directly affected by irrigation with reclaimed water. One gram of fish tissue homogenate was extracted by accelerated solvent extraction with methylene chloride followed by mixed-mode cation exchange solid phase extraction (SPE) cleanup and analyzed by liquid chromatography-tandem mass spectrometry. Compared to previously reported methods, the protocol produces cleaner extracts resulting in lower method detection limits. Similarly, an SPE method based on Oasis HLB cartridges was used to concentrate and cleanup reclaimed and surface water samples. Among the 11 target compounds analyzed, trimethoprim, caffeine, sulfamethoxazole, diphenhydramine, diltiazem, carbamazepine, erythromycin, and fluoxetine were consistently detected in reclaimed water. Caffeine, diphenhydramine, and carbamazepine were consistently detected in fish and surface water samples. Bioaccumulation factors for caffeine, diphenhydramine, and carbamazepine in mosquito fish (Gambusia holbrooki) were calculated at 29 ± 26, 821 ± 422, and 108 ± 144, respectively. This is the first report of potential accumulation of caffeine in fish from a water body directly influenced by reclaimed water.

    Adenosine-5'-triphosphate (ATP) is primarily known as a cellular source of energy. Increased ATP levels may have the potential to enhance body composition. A novel, proprietary blend of ancient peat and apple extracts has been reported to increase ATP levels, potentially by enhancing mitochondrial ATP production. Therefore, the purpose of this investigation was to determine the supplement's effects on body composition when consumed during 12 weeks of resistance training. Twenty-five healthy, resistance-trained, male subjects (age, 27.7 ± 4.8 years; height, 176.0 ± 6.5 cm; body mass, 83.2 ± 12.1 kg) completed this study. Subjects supplemented once daily with either 1 serving (150 mg) of a proprietary blend of ancient peat and apple extracts (TRT) or placebo (PLA). Supervised resistance training consisted of 8 weeks of daily undulating periodized training followed by a 2-week overreach and a 2-week taper phase. Body composition was assessed using dual-energy X-ray absorptiometry and ultrasound at weeks 0, 4, 8, 10, and 12. Vital signs and blood markers were assessed at weeks 0, 8, and 12. Significant group × time (p < 0.05) interactions were present for ultrasound-determined cross-sectional area, which increased in TRT (+0.91 cm(2)) versus PLA (-0.08 cm(2)), as well as muscle thickness (TRT: +0.46; PLA: +0.04 cm). A significant group × time (p < 0.05) interaction existed for creatinine (TRT: +0.06; PLA: +0.15 mg/dL), triglycerides (TRT: +24.1; PLA: -20.2 mg/dL), and very-low-density lipoprotein (TRT: +4.9; PLA: -3.9 mg/dL), which remained within clinical ranges. Supplementation with a proprietary blend of ancient peat and apple extracts may enhance resistance training-induced skeletal muscle hypertrophy without affecting fat mass or blood chemistry in healthy males.

    Body dissatisfaction has been linked to a number of poor health outcomes, including eating disorders. However, very few studies have investigated body dissatisfaction among immigrant adolescents. Using inductive qualitative inquiry, this study recruited a purposeful sample of immigrant adolescents (N=18, 78% female) with an eating disorder (n=8) and without an eating disorder (n=10). All adolescents were between 16 and 19 years of age (M=16.80, SD=0.89) and were recruited from three municipalities in Ontario. Each adolescent participated in a face-to-face, qualitative interview. Content analysis revealed descriptions of body image that were similar across the sample. The main themes emerging from this work include (a) the "moderately slim" and "moderately muscular" ideal, (b) the "slim and curvy paradox," (c) "ideal" privilege, (d) having an "expected" appearance, and (e) wishful comparisons. Findings have implications for reducing appearance-related dissatisfaction among immigrant adolescents in Canada. PMID:26363357

    Purpose: Despite the importance of body satisfaction on self concept and well being, there is little study about it or its consequences in Iranian populations, a part of Asian culture. The aim of this study was the assessment of body satisfaction and body management strategies in Iranian university students. Work method: This survey was performed based on a self-administrated questionnaire in 535 university and post graduate students. Work results: About 2/3rd of the students had moderate to severe body dissatisfaction and 40% of the students were using body management methods. Rhinoplasty and heavy exercise were the most frequent body management methods in women and men, respectively. Conclusion: Widespread research on body satisfaction prevalence and its management behaviors in the general population can be effective in reducing the negative health, social and economic consequences of harmful behaviors.

    Background Declines in cognitive functioning are a normal part of aging that can affect daily functioning and quality of life. This study will examine the impact of an exercise training program, and a combined exercise and cognitive training program, on the cognitive and physical functioning of older adults. Methods/Design Fit Bodies, Fine Minds is a randomized, controlled trial. Community-dwelling adults, aged between 65 and 75 years, are randomly allocated to one of three groups for 16 weeks. The exercise-only group do three 60-minute exercise sessions per week. The exercise and cognitive training group do two 60-minute exercise sessions and one 60-minute cognitive training session per week. A no-training control group is contacted every 4 weeks. Measures of cognitive functioning, physical fitness and psychological well-being are taken at baseline (0 weeks), post-test (16 weeks) and 6-month follop (40 weeks). Qualitative responses to the program are taken at post-test. Discussion With an increasingly aged population, interventions to improve the functioning and quality of life of older adults are particularly important. Exercise training, either alone or in combination with cognitive training, may be an effective means of optimizing cognitive functioning in older adults. This study will add to the growing evidence base on the effectiveness of these interventions. Trial Registration Australian Clinical Trials Register: ACTRN012607000151437 PMID:17915035

    BCL-2 proteins have been implicated in the control of glucose homeostasis and metabolism in different cell types. Thus, the aim of this study was to determine the role of the pro-apoptotic BH3-only protein, p53-upregulated-modulator-of-apoptosis (PUMA), in metabolic changes mediated by diet-induced obesity, using PUMA deficient mice. At 10 weeks of age, knockout and wild type mice either continued consuming a low fat chow diet (6% fat), or were fed with a high fat diet (23% fat) for 14–17 weeks. We measured body composition, glucose and insulin tolerance, insulin response in peripheral tissues, energy expenditure, oxygen consumption, and respiratory exchange ratio in vivo. All these parameters were indistinguishable between wild type and knockout mice on chow diet and were modified equally by diet-induced obesity. Interestingly, we observed decreased food intake and ambulatory capacity of PUMA knockout mice on high fat diet. This was associated with increased adipocyte size and fasted leptin concentration in the blood. Our findings suggest that although PUMA is dispensable for glucose homeostasis in lean and obese mice, it can affect leptin levels and food intake during obesity. PMID:27033313

  9. Motivation for eating behaviour in adolescent girls: the body beautiful.

    Hill, Andrew J

    2006-11-01

    Body dissatisfaction is commonplace for teenage girls and is associated with dieting and unhealthy weight-control behaviours. The idealisation and pursuit of thinness are seen as the main drivers of body dissatisfaction, with the media prominent in setting thin body ideals. Television and consumer magazine production in the UK are extensive, annually releasing 1x10(6) h programming and >3000 magazine titles. Their engagement by adolescent girls is high, and in surveys girls identify thin and revealing body images as influential to the appeal of thinness and their pursuit of dieting. Experimental studies show a short-term impact of these images on body dissatisfaction, especially in teenagers who are already concerned about body image. Magazine images appear more influential than television viewing. For many adolescents selecting thin-image media is purposive, permitting comparison of themselves with the models or celebrities featured. Indeed, the impact of the media needs to be understood within a social context, as engagement is often a highly-social process. Media influence is uneven because of differences in its content and manner of communication, and individual differences in vulnerability to its content. Greater social responsibility on the part of the media and better media literacy by children would be beneficial. For those working in adolescent nutrition it is a reminder that adolescent food choice and intake are subject to many competing, contradictory and non-health-related determinants. PMID:17181904

    This text tries to understand the Nursing team and their (dis)satisfactions in the work. We consider the association with the theory of basic human needs of Abraham Maslow as a way to systemize and to comprehend the recurrent situations and the day-by-day Nursing issues. The necessities are structuralized hierarchically in physiological, security, social, auto-esteem and auto-accomplishment indicating the degree of satisfaction (from the disease to the fullness) of an individual or group. The advantage of this approach consists of being able to use the solid, depth and rich Maslow theory in concrete and particular situations of the Nursing team. PMID:17340737

    This paper investigates nonpayment behavior in Guatemala. Determinants of nonpayment behavior are identified through zero-inflated negative binomial regression models in order to take into account particular distributional characteristics of the amount of outstanding payments. Findings indicate that nonpayment behavior is a demonstration of consumer dissatisfaction with current water services. The amount of outstanding bill payments also responds to system unreliability. Results also suggest that nonpayment behaviors are more prominent in community-managed systems than in municipal systems. No evidence was found on a potential relationship between nonpayment behavior and household income. Policy implications are discussed.

    By reducing energy density, low-energy sweeteners (LES) might be expected to reduce energy intake (EI) and body weight (BW). To assess the totality of the evidence testing the null hypothesis that LES exposure (versus sugars or unsweetened alternatives) has no effect on EI or BW, we conducted a systematic review of relevant studies in animals and humans consuming LES with ad libitum access to food energy. In 62 of 90 animal studies exposure to LES did not affect or decreased BW. Of 28 reporting increased BW, 19 compared LES with glucose exposure using a specific 'learning' paradigm. Twelve prospective cohort studies in humans reported inconsistent associations between LES use and body mass index (-0.002 kg m(-)(2) per year, 95% confidence interval (CI) -0.009 to 0.005). Meta-analysis of short-term randomized controlled trials (129 comparisons) showed reduced total EI for LES versus sugar-sweetened food or beverage consumption before an ad libitum meal (-94 kcal, 95% CI -122 to -66), with no difference versus water (-2 kcal, 95% CI -30 to 26). This was consistent with EI results from sustained intervention randomized controlled trials (10 comparisons). Meta-analysis of sustained intervention randomized controlled trials (4 weeks to 40 months) showed that consumption of LES versus sugar led to relatively reduced BW (nine comparisons; -1.35 kg, 95% CI -2.28 to -0.42), and a similar relative reduction in BW versus water (three comparisons; -1.24 kg, 95% CI -2.22 to -0.26). Most animal studies did not mimic LES consumption by humans, and reverse causation may influence the results of prospective cohort studies. The preponderance of evidence from all human randomized controlled trials indicates that LES do not increase EI or BW, whether compared with caloric or non-caloric (for example, water) control conditions. Overall, the balance of evidence indicates that use of LES in place of sugar, in children and adults, leads to reduced EI and BW, and possibly also

    Some factors that may affect human perception thresholds of the vertical whole-body vibrations were investigated in two laboratory experiments with recumbent subjects. In the first experiment, the effects of gender and age of subjects on perception were investigated with three groups of 12 subjects, i.e., young males, young females and old males. For continuous sinusoidal vibrations at 2, 4, 8, 16, 31.5 and 63 Hz, there were no significant differences in the perception thresholds between male and female subjects, while the thresholds of young subjects tended to be significantly lower than the thresholds of old subjects. In the second experiment, the effect of vibration duration was investigated by using sinusoidal vibrations, at the same frequencies as above, modulated by the Hanning windows with different lengths (i.e., 0.5, 1.0, 2.0 and 4.0 s) for 12 subjects. It was found that the peak acceleration at the threshold tended to decrease with increasing duration of vibration. The perception thresholds were also evaluated by the running root-mean-square (rms) acceleration and the fourth power acceleration method defined in the current standards. The differences in the threshold of the transient vibrations for different durations were less with the fourth power acceleration method. Additionally, the effect of the integration time on the threshold was investigated for the running rms acceleration and the fourth power acceleration. It was found that the integration time that yielded less differences in the threshold of vibrations for different durations depended on the frequency of vibration.

  15. Study: Long nursing shifts linked to burnout, job dissatisfaction, negative patient assessments.

    PubMed

    2013-02-01

    While nurses often choose to work 12-hour shifts, there is new evidence that too many of these longer shifts can lead to burnout and job dissatisfaction. Further, a new study suggests that patients are less satisfied with their care when nurses are working longer shifts, and patient outcomes may suffer as well. Experts recommend education around this issue for both staff nurses and nurse managers, and they urge administrators to devise sensible scheduling solutions. A three-year study, involving 23,000 registered nurses from four states, showed that nurses working shifts of 10 hours or longer were up to two and a half times more likely to experience burnout and dissatisfaction with their jobs than nurses working shorter shifts. Also, the study showed that seven out of 10 patient outcomes were adversely impacted by the longest nursing shifts. The Cleveland Clinic's 'parent shift' gives nurses the option of working shifts of six hours or less in exchange for less pay and no benefits. Administrators use these nurses to help their units manage busy hours or patient surges. PMID:23484222

    Female athletes experience pressure to conform to social and sporting norms concerning body weight. This study compared general and sporting body dissatisfaction and disordered eating symptomatology among 320 elite, recreational, and noncompetitive female athletes aged 17 to 30 years competing in leanness focused sports and nonleanness focused sports. Participants completed an online questionnaire including demographic questions, the Eating Attitudes Test, and the Figure Rating Scale. Athletes from leanness focused sports reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of participation level. Elite athletes reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of sport type, and differences between recreational and noncompetitive athletes were not found. More than 60% of elite athletes from leanness focused and nonleanness focused sports reported pressure from coaches concerning body shape. The findings have important implications for identifying risk factors for eating disorders among female athletes, where athletes who compete at elite level and those who compete in leanness focused sports at any level may be at higher risk for developing eating disorders.

    2014-09-01

    Body image dissatisfaction and unfavourable social comparisons are significant risk factors to eating psychopathology. Nevertheless, the impact of these negative experiences depends on the cognitive and emotional processes involved. Previous research has shown that cognitive fusion is a nuclear process linked to psychological inflexibility, but its role on body image and eating difficulties remains unclear. This study aims to explore a model of the mediational role of body image-related cognitive fusion (CF-BI) on the relationship between body dissatisfaction, unfavourable social comparisons, and eating psychopathology in a sample of 345 female students. Results from path analyses show that the impact of unfavourable social comparisons on eating psychopathology is fully mediated by CF-BI. Moreover, CF-BI also revealed a mediational effect on the relationship between body image dissatisfaction and the severity of eating symptoms, in spite of the fact that a direct effect of body dissatisfaction still exists. The tested model highlights the crucial role that cognitive fusion, in the specific domain of body image, plays in the relationship between risk factors and the severity of disordered eating attitudes and behaviours. Furthermore, these findings present empirical support for the relevance of addressing acceptance and cognitive defusion techniques to prevent and treat eating disorders. PMID:24858833

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

    2014-04-01

    Although research consistently shows that images of thin women in the media (media body ideals) affect women negatively (e.g., increased weight dissatisfaction and food intake), this effect is less clear among restrained eaters. The majority of experiments demonstrate that restrained eaters - identified with the Restraint Scale - consume more food than do other participants after viewing media body ideal images; whereas a minority of experiments suggest that such images trigger restrained eaters' dietary restraint. Weight satisfaction and mood results are just as variable. One reason for these inconsistent results might be that different methods of image exposure (e.g., slideshow vs. film) afford varying levels of attention. Therefore, we manipulated attention levels and measured participants' weight satisfaction and food intake. We based our hypotheses on the elaboration likelihood model and on restraint theory. We hypothesised that advertent (i.e., processing the images via central routes of persuasion) and inadvertent (i.e., processing the images via peripheral routes of persuasion) exposure would trigger differing degrees of weight dissatisfaction and dietary disinhibition among restrained eaters (cf. restraint theory). Participants (N = 174) were assigned to one of four conditions: advertent or inadvertent exposure to media or control images. The dependent variables were measured in a supposedly unrelated study. Although restrained eaters' weight satisfaction was not significantly affected by either media exposure condition, advertent (but not inadvertent) media exposure triggered restrained eaters' eating. These results suggest that teaching restrained eaters how to pay less attention to media body ideal images might be an effective strategy in media-literary interventions. PMID:24854816

    This study characterizes the profile of women (N = 1,789) ages 50 and over who report body size satisfaction on a figure rating scale. Satisfied women (12.2%) had a lower body mass index and reported fewer eating disorder symptoms, dieting behaviors, and weight and appearance dissatisfaction. Interestingly, satisfied women exercised more than dissatisfied women, and weight and shape still played a primary role in their self-evaluation. Weight monitoring and appearance-altering behaviors did not differ between groups. Body satisfaction was associated with better overall functioning. This end point appears to represent effortful body satisfaction rather than passive contentment. PMID:24116991
