    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.

    Barbie doll ownership is high among girls in early primary school. It has been suggested that exposure to Barbie impacts negatively on body image. The present study sought to investigate the effect of exposure to Barbie on young girls' thin-ideal internalisation, body esteem, and body dissatisfaction. Participants were 160 girls (aged 5-8 years) from Adelaide, South Australia. They were randomly allocated one of three Barbie conditions (physical engagement, physical observation, print observation) or to a control toy. Results indicated that exposure to Barbie, irrespective of format, led to higher thin-ideal internalisation than exposure to the control, but had no impact on body esteem or body dissatisfaction. This suggests that interacting with Barbie may encourage girls in early primary school to adopt a preference for a thin body, but with no immediate effect on body image. The long-term impact of Barbie exposure on body image remains unknown. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

    Full Text Available Body dissatisfaction can contribute to social, occupational and recreational losses, constituting a risk factor to health. This study aimed to evaluate the predictors of body dissatisfaction regarding demographic variables, media and life satisfaction among university students. The sample consisted of 321 participants older than 18 years. Body dissatisfaction, life dissatisfaction and media messages internalization were evaluated by Escala de Silhuetas para Adultos Brasileiros, Subjective Well-Being Scale and Sociocultural Attitudes Towards Appearance Questionnaire-3, respectively. Data were collected by an online survey tool (SurveyMonkey® and were analyzed using multiple linear regression. It was found that body dissatisfaction was positively related to inaccuracy in the perception of body size, Body Mass Index, life dissatisfaction, media messages internalization and television exposure. These findings evidence the importance of these predictors in the dynamics of body dissatisfaction, which support the development of preventive and treatment interventions.

    Full Text Available Abstract: Despite the importance of body satisfaction on one’s self image and well-being, little has been written about body image or how it affects people in Iran. The aim of this study is to assess body dissatisfaction and its risk factors in the general Iranian population. The sample size for this cross-sectional study included approximately 1,200 participants (both male and female and was conducted in 2011. Body dissatisfaction (based on the Figure Rating Scale, demographic characteristics, socioeconomic status, body mass index (BMI and use of the media were recorded. Nearly two thirds of the participants were included in the middle age group and roughly half of them had a university education. Approximately two thirds of the participants were satisfied with their body. The mean score of body dissatisfaction in women was greater than men (p < 0.0001. Age, gender, marital status and BMI had a significant relationship with body dissatisfaction. The finding of this study demonstrates that in Iran, body dissatisfaction and it consequences must be addressed. While the prevalence and pattern of body dissatisfaction in Iran is as high as other Asian countries, considering cultural variation within Asian countries is also important.

    Body dissatisfaction is prevalent in women's artistic gymnastics (WAG). Cross-sectional research points to social and individual risk factors, however it does not account for potential changes in body dissatisfaction during an athletic season. This study aimed to determine how gymnasts' body dissatisfaction, risk factors for eating disorders, media internalisation, perfectionism and mood state change during pre-competition, competition and post-competition seasons and to identify how these psychosocial indicators impact on body dissatisfaction during the athletic year. The sample consisted of 20 Brazilian elite women's artistic gymnasts aged 10-16 years. Data were obtained from a 9-month study using: Body Shape Questionnaire (BSQ); Eating Attitude Test-26; Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3); Multidimensional Perfectionism Scale (MPS); Brunel Mood Scale (BRUMS) and triceps and subscapular skinfolds. Body dissatisfaction was higher during the competition season and disordered eating, perfectionism and vigour values were higher in the pre-competition season. Disordered eating has been found as the strongest predictor of body dissatisfaction during all seasons, and mood state partly contributed to body dissatisfaction in the competitive season. Stakeholders should understand that body dissatisfaction and the prevalence of disordered eating may change over time.

    To inspire effective health promotion campaigns, we tested the relationship of ideal body size and body size dissatisfaction with (1) the potential resulting health-influencing factors diet, physical activity and well-being; and (2) with media as a potential influencer of body ideals. This is a cross-sectional study in 370 Ghanaian adolescents (aged 11-18 years). Questionnaires included disordered eating (EAT26), diet quality (FFQ), physical activity (IPAQ), well-being (KINDL) and media influence on appearance (SATAQ: pressure, internalisation and information). Ideal body size and body size dissatisfaction were assessed using the Stunkard figure rating scale. Body mass index (BMI), skinfolds and waist were measured. Linear regressions were adjusted for gender, age and parental education. Also, mediation was tested: 'can perceived media influence play a role in the effects of actual body size on body size dissatisfaction?'. Body size dissatisfaction was associated with lower well-being and more media influence (pressure and internalisation) but not with physical activity, diet quality or disordered eating. An underweight body size ideal might worsen disordered eating but was not significantly related to the other predictors of interest. Only a partial mediation effect by media pressure was found: especially overweight adolescents felt media pressure, and this media pressure was associated with more body size dissatisfaction. To prevent disordered eating and low well-being, health messages should include strategies that reduce body size dissatisfaction and increase body esteem by not focussing on the thin body ideal. Changing body size ideals in the media might be an appropriate way since media pressure was a mediator in the BMI-dissatisfaction relation. Copyright © 2017 The Royal Society for Public Health.

    Full Text Available 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.

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

    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. © The Author(s) 2016.

    2017-06-01

    The present experiment aimed to investigate the impact of the addition of disclaimer labels to fashion magazine shoots on women's body dissatisfaction. Participants were 320 female undergraduate students who viewed fashion shoots containing a thin and attractive model with no disclaimer label, or a small, large, or very large disclaimer label, or product images. Although thin-ideal fashion shoot images resulted in greater body dissatisfaction than product images, there was no significant effect of disclaimer label. Internalisation of the thin ideal was found to moderate the effect of disclaimer label, such that internalisation predicted increased body dissatisfaction in the no label and small label conditions, but not in the larger label conditions. Overall, the results showed no benefit for any size of disclaimer label in ameliorating the negative effect of viewing thin-ideal media images. It was concluded that more extensive research is required before the effective implementation of disclaimer labels. Copyright © 2017 Elsevier Ltd. All rights reserved.

A total of 629 adolescents aged 13 to 17 years from urban and rural areas participated in the study. Demographic variables (gender, age, area of residence, anthropometric measurements (body weight, height, skinfold thickness and body image data were collected. BMI (underweight: 25 kg/m² and the sum of two skinfold thicknesses, Σ2SF (girls: low: 36 mm; boys: low: 25 mm were then calculated. The prevalence of body image dissatisfaction was similar (p≥0,05 among rural (64,2% and urban adolescents (62,8%. Boys wished to increase the size of their body silhouette (41,3%, whereas girls wished to reduce it (50,5% (p<0,001. Adolescents with low and excess weight based on BMI and with high Σ2SF presented a 3,14, 8,45 and 2,08 times higher chance of body image dissatisfaction, respectively. A high prevalence of body image dissatisfaction was observed among adolescents from rural and urban areas. An unhealthy nutritional status and body adiposity increase the chances of body image dissatisfaction. These findings emphasize the social pressure on girls to remain slim and on boys to attain an athletic body.

    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. © The Author(s) 2014.

    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.

  18. Holding fat stereotypes is associated with lower body dissatisfaction in normal weight Caucasian women who engage in body surveillance.

    2014-09-01

    This study examined the moderating effect of body surveillance on the relationship between fat stereotype endorsement and body dissatisfaction in normal weight women. Participants (N=225) completed online measures of fat stereotyping, body surveillance, body dissatisfaction, and internalized thin ideals. After accounting for thin ideals, body surveillance moderated the relationship between fat stereotypes and body dissatisfaction. Contrary to hypotheses, higher fat stereotype endorsement predicted lower body dissatisfaction in women with higher body surveillance. Conversely, higher fat stereotype endorsement predicted greater body dissatisfaction in women with lower body surveillance. Thus, endorsing fat stereotypes appears protective against body dissatisfaction in normal weight women who extensively engage in body surveillance. For women who hold fat stereotypes and report high body surveillance, we propose that downward appearance comparison may create a contrast between themselves and the people with overweight whom they denigrate, thus improving body dissatisfaction.

    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.

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

    2011-03-01

    The current study examined self-worth and body size dissatisfaction, and their association with maternal acculturation among obese Latino youth enrolled in a community-based obesity intervention program. Upon entry to the program, a sample of 113 participants reported global self-worth comparable to general population norms, but lower athletic competence and perception of physical appearance. Interestingly, body size dissatisfaction was more prevalent among younger respondents. Youth body size dissatisfaction was associated with less acculturated mothers and higher maternal dissatisfaction with their child's body size. By contrast, although global self-worth was significantly related to body dissatisfaction, it was not influenced by mothers' acculturation or dissatisfaction with their own or their child's body size. Obesity intervention programs targeted to Latino youth need to address self-worth concerns among the youth as well as addressing maternal dissatisfaction with their children's body size.

    2012-01-01

    This study tested the direct effect of watching thin ideal children's television on body satisfaction in preadolescent girls (6-8 years old). A within-subject design was used in which girls (N = 51) were tested three times. They watched television clips in random order containing either (1) thin ideal animated characters or (2) animated characters with no thin ideal features or (3) 'real' human actors with no thin ideal features. After watching, their state body satisfaction was measured. Girls with higher levels of thin ideal internalisation showed higher body satisfaction after exposure to the thin ideal characters than after exposure to animated or real characters featuring no thin ideal features. No differences on body satisfaction between the exposure conditions were found in girls with lower levels of thin ideal internalisation. The results might suggest that young girls who internalised the thin ideal are inspired by thin ideal characters in children's media.

    2012-03-01

    Given the theoretically postulated causal pathway from low self-esteem on body dissatisfaction, the aim of the present study was to experimentally test this linkage before and after a mirror exposure in body dissatisfied females. Thirty-six women with high body dissatisfaction (HBD) and 39 women with low body dissatisfaction (LBD) received either a positive or a negative implicit manipulation of self-esteem and participants' actual body dissatisfaction and negative emotions were assessed (T1). Following that, they underwent a one minute mirror exposure and actual body dissatisfaction and emotions were assessed once more (T2). In the HBD group no effects of the self-esteem manipulation were found prior to the mirror exposure. However, the negative manipulation of self-esteem led to a significant increase of body dissatisfaction over the course of the mirror exposure. The positive manipulation of self-esteem did not decrease body dissatisfaction over the course of the mirror exposure. No effects of self-esteem on body dissatisfaction were found in the LBD group. Formal eating disorder diagnosis in study participants was not established. Therefore, the extension of the results to an eating disordered population is recommended. The results yield evidence of a close linkage between negative self-esteem and body dissatisfaction in individuals high on body dissatisfaction. Consistent with cognitive theories, this link is only apparent when shape and weight schemas are activated, e.g. by the confrontation with one's own body. Copyright © 2011 Elsevier Ltd.

    Body dissatisfaction, the negative subjective evaluation of one's body, is associated with many negative psychological and physical health consequences. One conceptualization of body dissatisfaction includes an experience of discrepancy between perceived actual and ideal body shapes. This paper reviews the literature on three facets of body dissatisfaction from the framework of self-discrepancy theory: perceptions of current weight, ideal body weight, and the relative importance of conforming to ideals. We review components of body dissatisfaction among healthy individuals and eating-disordered individuals. We also address the conceptualization's relationship among body dissatisfaction, weight history, and dieting to expand the impact of body dissatisfaction research and to provide more information on the nature and treatment of eating disorders.

    Through multiple group structural equation modeling analyses, path models were used to test the predictive effects of sport type and both interpersonal (i.e., mothers' body dissatisfaction, family dynamics) and intrapersonal factors (i.e., athletic self-efficacy, body mass index [BMI]) on high school female sport participants' (N=627) body dissatisfaction. Sport types were classified as esthetic/lean (i.e., gymnastics), non-esthetic/lean (i.e., cross-country), or non-esthetic/non-lean (i.e., softball). Most participants reported low body dissatisfaction, and body dissatisfaction did not differ across sport types. Nevertheless, mothers' body dissatisfaction was positively associated with daughters' body dissatisfaction for non-esthetic/lean and non-esthetic/non-lean sport participants, and high family cohesion was predictive of body dissatisfaction among non-esthetic/lean sport participants. Across sport types, higher BMI was associated with greater body dissatisfaction, whereas greater athletic self-efficacy was associated with lower body dissatisfaction. These findings highlight the complex relationship between interpersonal and intrapersonal factors and body dissatisfaction in adolescent female sport participants. Copyright © 2012.

    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.

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

    This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed.

    We examined the associations among self-reported body image, self-esteem, and measured body mass index (BMI) in El-Salvadoran American youth. Higher BMI was associated with body size dissatisfaction, lower peer esteem, and attempts to lose weight. Body size dissatisfaction was also significantly related to self-esteem in these El-Salvadoran American youth.

    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. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Research on emotional functioning, body dissatisfaction, and disordered eating in males is predominated by studies of negative affect and emotion regulation. Other aspects of emotional functioning, namely emotion recognition and attentional biases toward emotional stimuli, have received little empirical attention. The present study investigated the unique associations between different aspects of men's emotional functioning and their disordered eating attitudes, muscularity dissatisfaction, and body fat dissatisfaction. Results from 132 male undergraduates showed that muscularity dissatisfaction was uniquely associated with both emotion regulation difficulties and an attentional bias toward rejecting faces. Body fat dissatisfaction was not uniquely associated with any aspect of emotional functioning. Disordered eating was uniquely associated with emotion regulation difficulties. Collectively, the results indicate differences in the patterns of associations between men's emotional functioning and their body dissatisfaction and disordered eating. Copyright © 2013 Elsevier Ltd.

    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.

    To determine the association between body image dissatisfaction (BID) and depressive symptoms in adolescents from a school in Lima, Peru. A cross-sectional study was performed through a census of 875 high-school students, aged 13 to 17 years, from a school in Lima. Participants completed a survey containing the Body Shape Questionnaire (BSQ) and the Patient Health Questionnaire-9 (PHQ-9). Data regarding demographics, alcohol and tobacco use, self-esteem, and family history of depression were also obtained. To identify associated factors, Poisson regression with robust variance was used. Prevalence ratios with 95% confidence intervals were calculated. Of the 875 adolescents, 55.8% were male. The mean age was 14.1±1.5 years. Depressive symptoms were observed in 19.9% of participants. An association between BID and depressive symptoms was found. Alcohol and tobacco use were also associated with the outcome of interest. Teens who had BID were 3.7 times more likely to report depressive symptoms. Additionally, those who used tobacco or alcohol were 1.5 and 1.4 times more likely to have depressive symptoms, respectively. Further studies targeting other populations and using longitudinal designs are recommended.

    2009-11-01

    The relationship between social comparison and body dissatisfaction was examined using meta-analysis. Several demographic and methodological variables were examined as potential moderators. Data from 156 studies (189 effect sizes) showed that social comparison was related to higher levels of body dissatisfaction. The effect for social comparison and body dissatisfaction was stronger for women than men and inversely related to age. This effect was stronger when social comparison was directly measured rather than inferred. No differences emerged for the presence of eating psychopathology, study design, or object of comparison. Results confirm theory and research suggesting that comparing oneself unfavorably to another on the basis of appearance may lead to dissatisfaction with one's own appearance. Moderator variables refine our understanding of the social comparison-body dissatisfaction relationship. These constructs and their relationship should be explored further in future studies.

    Body checking (BC) and body image avoidance (BIA) have been proposed as etiological and maintaining mechanisms for eating disorder (ED) pathology. To date, no comprehensive review summarizes the relationships of BC and BIA with ED pathology, body image dissatisfaction, or mood/affect. Meta-analyses examined the relationships of BC and BIA with ED pathology, body image dissatisfaction, and mood/affect. Gender, publication status, and presence or absence of ED diagnoses were examined as potential moderators. Results showed strong relationships between BC and ED pathology (ρ = 0.588) and BC and body image dissatisfaction (ρ = 0.631) and a moderate relationship between BC and mood/affect (ρ = 0.385). Similarly, results showed strong relationships between BIA and ED pathology (ρ = 0.553) and BIA and body image dissatisfaction (ρ = 0.543) and a moderate relationship between BIA and mood/affect (ρ = 0.392). Overall, limited evidence supported publication bias; however, publication bias may exist in the relationship between BIA and body image dissatisfaction in the literature. Subgroup moderator analyses suggested that gender moderates the strength of the relationships between BC and ED pathology, body image dissatisfaction, and mood/affect and between BIA and body image dissatisfaction. Results are consistent with cognitive-behavioral models of ED pathology that suggest BC and BIA are behavioral expressions of overvaluation of weight and shape. Notably, more published research has investigated BC than BIA. Future studies, incorporating methods such as meta-analytic structural equation modeling, should examine these variables to further test cognitive-behavioral models of ED development and maintenance. © 2018 Wiley Periodicals, Inc.

    Body dissatisfaction is strongly associated with quality of life impairment among both male and female adults, and the strength of this relationship is comparable between the sexes. Whether this is the case among adolescents, however, is unclear. Adolescent girls (n = 1,135) and boys (n = 531) aged 12-18 years were recruited from secondary schools located in the Australian Capital Territory, Australia. Students completed a survey that included measures of body dissatisfaction, eating disorder symptoms, and psychosocial health- and physical health-related quality of life. Girls reported higher levels of dissatisfaction than boys for each of the 12 body features assessed. The strength of the adverse associations between body dissatisfaction and quality of life impairment did not, however, differ by sex, and this was the case for both physical health-related and psychosocial quality of life domains. For both girls and boys, associations between body dissatisfaction and both quality of life impairment persisted after controlling for eating disorder symptoms, body mass index, and other covariates. While levels of body dissatisfaction remain higher in girls than in boys, the adverse impact of body dissatisfaction on adolescents' quality of life does not appear to differ by sex. This impact entails impairment in both physical health and psychosocial quality of life domains and does not appear to be accounted for by an association between body dissatisfaction and eating disorder pathology. The findings support the need to conceive of body dissatisfaction as a public health concern in its own right. Copyright © 2017 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Full Text Available Abstract Background Childhood obesity is a continuing problem in the UK and South Asian children represent a group that are particularly vulnerable to its health consequences. The relationship between body dissatisfaction and obesity is well documented in older children and adults, but is less clear in young children, particularly South Asians. A better understanding of this relationship in young South Asian children will inform the design and delivery of obesity intervention programmes. The aim of this study is to describe body image size perception and dissatisfaction, and their relationship to weight status in primary school aged UK South Asian children. Methods Objective measures of height and weight were undertaken on 574 predominantly South Asian children aged 5-7 (296 boys and 278 girls. BMI z-scores, and weight status (underweight, healthy weight, overweight or obese were calculated based on the UK 1990 BMI reference charts. Figure rating scales were used to assess perceived body image size (asking children to identify their perceived body size and dissatisfaction (difference between perceived current and ideal body size. The relationship between these and weight status were examined using multivariate analyses. Results Perceived body image size was positively associated with weight status (partial regression coefficient for overweight/obese vs. non-overweight/obese was 0.63 (95% CI 0.26-0.99 and for BMI z-score was 0.21 (95% CI 0.10-0.31, adjusted for sex, age and ethnicity. Body dissatisfaction was also associated with weight status, with overweight and obese children more likely to select thinner ideal body size than healthy weight children (adjusted partial regression coefficient for overweight/obese vs. non-overweight/obese was 1.47 (95% CI 0.99-1.96 and for BMI z-score was 0.54 (95% CI 0.40-0.67.

    The current study reviewed relationships between gender roles and (a) eating pathology, (b) body dissatisfaction, and (c) muscle dissatisfaction among men via meta-analysis. Moderators of sexual orientation and type of gender role measure were also investigated. Results revealed the relationship between femininity and eating and body-related variables did not significantly differ from zero. Sexual orientation moderated the relationship between femininity and muscle dissatisfaction (i.e., femininity was negatively related to muscle dissatisfaction for heterosexual but not gay men). Masculinity was negatively associated with eating pathology and body dissatisfaction. Type of masculinity measure moderated the relationship between masculinity and body dissatisfaction (i.e., trait-based measures produced a negative association, multidimensional measures yielded nonsignificant relationships). Type of masculinity measure produced a cross-over interaction when examining muscle dissatisfaction (i.e., trait-based instruments yielded a negative association and multidimensional instruments revealed a positive relationship). Findings highlight the salience of masculinity in men's eating and body concerns. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed.

    This study investigated how dissatisfaction with various aspects of the body is associated with overall body dissatisfaction among female adolescents in Western and Asian cultures. Data used in the study were obtained from 58 Malaysian Malays, 95 Malaysian Chinese, 242 Chinese from China, and 81 non-Asian Australians aged 12-19 years (M=15.72, SD=1.72) who were recruited from high schools. Participants completed a questionnaire assessing dissatisfaction with their body overall, and dissatisfaction with varying aspects of their body. Malaysian Chinese were the most dissatisfied with their bodies. After controlling for body mass index (BMI), age and dissatisfaction with weight/shape, upper, middle and lower body, and muscles, dissatisfaction with the face was positively correlated with overall body dissatisfaction among Malaysian Malays and Australians. These findings demonstrate the importance of using assessment measures that address all possible areas of body focus as well as being tailored to the relevant culture. Copyright © 2012 Elsevier Ltd.

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

  11. Body dissatisfaction, trait anxiety and self-esteem in young men

    Directory of Open Access Journals (Sweden)

    Czeglédi Edit

    2015-01-01

    Full Text Available Background and purpose: Body image dissatisfaction has recently been described as 'normative' for both men and women. Despite intense theoretical interest in a multidimensional concept of male body image, comprehensive models have rarely been assessed empirically. The aim of this study was therefore to examine the relationship between body image and self-esteem among men in a multivariate model. Methods: Participants of this cross-sectional questionnaire study were 239 male university students (mean age: 20.3 years, SD=2.78 years, range: 18-39 years. Measures: self-reported anthropometric data, weightlifting activity, importance of appearance, perceived weight status, satisfaction with body height, Body Shape Questionnaire - Short form, Muscle Appearance Satisfaction Scale, Rosenberg Self-Esteem Scale. Results: Structural equation modeling showed that after controlling for age, BMI, weightlifting activity, the importance of appearance, and trait anxiety, only muscle dissatisfaction predicted lower self-esteem (β=-0.11, p=0.033. Neither height dissatisfaction nor weight dissatisfaction showed significant association with selfesteem. Muscle dissatisfaction partially mediated the relationship between trait anxiety and self-esteem (β=-0.04, p=0.049, R2=0.05. The model explained 50.4% of the variance in selfesteem. Conclusions: The results emphasize that trait anxiety might be a background variable in the relationship between males' body dissatisfaction and self-esteem, which should be considered in future studies and in the course of therapy.

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

    One publication reported that lower body satisfaction and lower education were independent predictors of depression in polycystic ovary syndrome (PCOS) in women. This study replicates that analysis using different instruments, and adds androgen levels to the model. 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. 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>.20) and similar body dissatisfaction (P≥.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 (Psymptoms in non-obese PCOS women (BMIPCOS, depression was unrelated to body dissatisfaction after controlling for age. 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 was associated with depression symptom severity in PCOS women after controlling for body dissatisfaction and age. Copyright © 2011 Elsevier Inc.

    The present study examined the relationship among weight, body dissatisfaction, and self-esteem in a large group of African American and white female dieters who were generally overweight and of middle to high socioeconomic status. Subjects were participants in a survey of dieting practices undertaken by Consumer Reports magazine. Major outcome measures included the Rosenberg Self-Esteem Scale and an assessment of shape and weight attitudes. No significant differences between African American and white women were found for body dissatisfaction, self-esteem, discrepancies between actual and ideal weight and shape, or the relationship between self-esteem and body dissatisfaction. Body mass index contributed less to body satisfaction scores in African American than in white women. This study provides a comparison of African American and white women in the upper social classes, and raises the possibility that previous findings of less body concern in African American women reflect class rather than race effects.

    To determine the prevalence of and factors associated with body image dissatisfaction among physical education students enrolled in a public university. This study evaluated 236 students and assessed body image perception (silhouette scale), sociodemographic variables (sex, age, parental education, marital status, university course, work, living arrangement, study shift, and income), physical activity level (International Physical Activity Questionnaire - Short Version), dietary habits, tobacco use, excessive intake of alcohol (questions from the tobacco, alcohol and drugs, and nutrition domains of the FANTASTIC instrument), and nutritional status (body mass index [BMI]). Descriptive analysis, the chi-square test, Fisher's exact test, and crude and adjusted multinomial regression were used. The prevalence of body image dissatisfaction was 69.5%; 44.1% were dissatisfied with excess weight. BMI ≥ 25.0 kg/m² was associated with dissatisfaction with excess weight; factors associated with dissatisfaction with slimness were being male, eating an unhealthy diet, and smoking tobacco. Our findings suggest that female college students with a BMI ≥ 25.0 kg/m² are more likely to present dissatisfaction with excess weight. Being male, eating an unhealthy diet, engaging in physical activity for smoking tobacco were the variables associated with dissatisfaction with thinness.

    Thin-ideal internalization is a robust risk factor for body dissatisfaction and eating pathology. Conversely, athletic-ideal internalization is often unrelated to body dissatisfaction, but predicts compulsive exercise (i.e., rigid, rule-driven exercise that is continued despite adverse consequences). Distinct personality traits could relate to internalization of different appearance ideals, which may be associated with divergent eating disorder outcomes. Past research has shown that neuroticism is related to body dissatisfaction, whereas extraversion and conscientiousness have been associated with regular and problematic exercise. The current study examined associations among personality traits (i.e., neuroticism, extraversion, conscientiousness), appearance-ideal internalization (i.e., thin- and athletic-ideal), and eating disorder cognitions/behaviors (i.e., body dissatisfaction, compulsive exercise) among 531 college men and women. Moreover, we tested whether appearance-ideal internalization mediated the relationships between personality traits with body dissatisfaction and compulsive exercise. As expected, body dissatisfaction was positively related to neuroticism, and compulsive exercise was positively associated with extraversion. Thin-ideal internalization positively correlated with neuroticism, athletic-ideal internalization positively correlated with conscientiousness, and both thin- and athletic-ideal internalization were positively related to extraversion. After controlling for gender, body mass index, the other appearance-ideal internalization, and the remaining personality traits, the indirect effects of both neuroticism and extraversion on body dissatisfaction through thin-ideal internalization were significant. Extraversion and conscientiousness were indirectly related to compulsive exercise through athletic-ideal internalization, whereas the indirect effect of neuroticism was dependent on covariates. As such, personality traits may be related to

    Introduction Emerging adults are particularly vulnerable to body image dissatisfaction and social anxiety. These bring about a host of negative outcomes, including compromised social adjustment and well-being. Fear of negative evaluation has been shown to be a core element of social anxiety, but it is rarely considered in studies of body image and its effects on social anxiety. This study aimed to bridge this gap by examining the role of fear of negative evaluation in the association between body image dissatisfaction and social anxiety. Methods A cross-sectional study using 80 Thai undergraduates (mean age of 21 years) was conducted by self-reported (questionnaire) measures. Body image dissatisfaction was measured with the short version of the Body Shape Questionnaire (BSQ-8C), fear of negative evaluation with the Brief Fear of Negative Evaluation Scale, and social anxiety with the Interaction Anxiousness Scale (IAS). Correlation and mediation analyses were conducted to assess how these constructs were related to one another. Results The key hypothesis was supported: positive associations were found among body image dissatisfaction, fear of negative evaluation and social anxiety, and the association between body image dissatisfaction and social anxiety was mediated by fear of negative evaluation. Discussion Generalizing from the current findings, ideas for possible amelioration of social anxiety are discussed.

    To analyze self-esteem, as well as the different peer influence components (messages, interactions and likability) as predictors of body dissatisfaction in children with obesity. A total of 123 children aged between 10 and 12 years were divided into two groups according to their body mass index. The group with obesity was comprised of 36 boys and 21 girls and the group with normal weight of 32 boys and 34 girls. All of the participants answered the Body Shape Questionnaire-16, the Inventory of Peer Influence on Eating Concerns, and the Rosenberg Self-Esteem Scale. The hierarchical multiple regression analysis for each group showed that likability and peer messages explain 67% of the body dissatisfaction variance in children with obesity and 54% in children with normal weight. Peer influence predicted body dissatisfaction in children; however, children with obesity assimilate messages from their peers differently compared with children with normal weight.

    Full Text Available Abstract This study aimed to evaluate the overall body dissatisfaction and in specific areas in adolescents who practice artistic gymnastic in elite and non-elite levels, and to analyze the influence of sociodemographic, anthropometric and maturational factors on body dissatisfaction. The research is characterized as transversal, quantitative, descriptive and correlational. The sample consisted of 285 adolescents, of both sexes, practicing gymnastics. They were divided into two groups: 245 non-elite athletes and 40 elite athletes. The participants were aged between 10 and 18 years (mean 12.86 ± 1.80 and were resident of the city of Três Rios-RJ. The assessment instruments were: Body Shape Questionnaire, Body Areas Scale, Critério de Classificação Econômica Brasil and socio-demographic questionnaire. Anthropometric and somatic maturation data were collected. The results showed that 24.9% of the non-elite athletes and 15% of elite athletes were dissatisfied with their body as a whole. For specific body areas, nonelite athletes were significantly more dissatisfied with their body area “weight” than the elite athletes. Sociodemographic and economic factors had no influence on overall body dissatisfaction. For non-elite athletes, only the body percentage of fat and somatic maturation were predictors for the overall body dissatisfaction and in specific areas, respectively. It was concluded that the non-elite athletes were more dissatisfied with their body and weight than the elite athletes.

    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.

    2016-03-01

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

    2005-09-01

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

    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.

    Two hundred and thirty-five adolescents completed a questionnaire on the subject of eating attitudes, self-esteem, reasons for exercise, and their ideal versus current body size and shape. As predicted, boys were as likely to want to be heavier as lighter, whereas very few girls desired to be heavier. Only girls associated body dissatisfaction with the concept of self-esteem. Male self-esteem was not affected by body dissatisfaction. Specific reasons for exercise were found to correlate with low self-esteem and disordered eating, regardless of sex. The results are discussed in relation to burgeoning published research in this area.

    To identify the prevalence of body image dissatisfaction and associated factors among students in Salvador, Brazil. A cross-sectional study involving a random sample of 1,494 (852 girls and 642 boys) adolescents between 11 and 17 years of age who were students in the public schools in Salvador, Brazil. Participants completed the Body Shape Questionnaire and the Eating Attitudes Test-26. Body image was characterized as satisfactory or unsatisfactory. We obtained demographic, anthropometric and economic information and information regarding the stage of maturation, self-perception of body weight, and consumption of sweetened beverages and diet soft drinks. To identify associated factors we used Poisson regression analysis. Body image dissatisfaction was present in 19.5% of the adolescents, with a prevalence of 26.6% among the girls and 10% among the boys. Independent of sex, the prevalence of body image dissatisfaction was higher among adolescents who were overweight or obese (girls, PR: 1.38, CI: 1.09-1.73 and boys, PR: 2.26, CI: 1.08-4.75), higher among those who perceived themselves as fat (girls, PR: 2.85, CI: 2.07-3.93 and boys, PR: 3.17, CI: 1.39-7.23), and higher among those who had negative attitudes toward eating (girls, PR: 2.42, CI: 1.91-3.08 and boys, PR: 4.67, CI: 2.85-7.63).. A reduction in body image dissatisfaction was only identified among underweight girls (PR: 0.12, CI: 0.03-0.49). A high occurrence of body image dissatisfaction was observed among the adolescents, and biological and behavioral factors were associated with this dissatisfaction.

A total of 832 university students (485 men with a mean age of 20.1 years (standard deviation = 4.6 participated in the study. Self-reported body weight and height were used for the calculation of body mass index. The students responded to the Body Shape Questionnaire and International Physical Activity Questionnaire. Data were analyzed using Fisher’s exact test, considering p < .05. The prevalence of body image dissatisfaction and physical inactivity was 10.1% and 14.5%, respectively. No significant association was observed between body image dissatisfaction and physical activity level. Body image dissatisfaction was associated with nutritional status in both genders (p < .05. University students with excess body weight should be encouraged to pursue a healthier lifestyle in order to promote an adequate nutritional status and also to improve their body image.

    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.

    Definition of factors influencing negative body image among obese women and analysis of the relationship between body dissatisfaction and personality variables. 63 patients participated in this study. The mean age of the obese subjects was 41.90 years (SD +/- 12.23) and the mean body mass index (BMI) was 37.09 kg/m2 (SD +/- 8.09). The control group consisted of 60 women with normal body weight. The Body Dissatisfaction Scale of EDI (Garner et al., 1984), the Self-Esteem Inventory (Coopersmith, 1983) and the Brief COPE (Carver, 1997) were used in the study. In the clinical sample of women suffering from obesity, we have found a correlation between body dissatisfaction and behavioural disengagement, four dimensions of self-esteem (general, social, family and professional) and coping strategies focused on planning and positive reinterpretation. The regression analysis revealed that use of emotional support, planning and general self-esteem were predictive factors for the body dissatisfaction in obesity. Body dissatisfaction seriously influences the social, professional and emotional obese women's self.

    The experiment investigated the impact on women's body dissatisfaction of different forms of label added to fashion magazine advertisements. Participants were 340 female undergraduate students who viewed 15 fashion advertisements containing a thin and attractive model. They were randomly allocated to one of five label conditions: no label, generic disclaimer label (indicating image had been digitally altered), consequence label (indicating that viewing images might make women feel bad about themselves), informational label (indicating the model in the advertisement was underweight), or a graphic label (picture of a paint brush). Although exposure to the fashion advertisements resulted in increased body dissatisfaction, there was no significant effect of label type on body dissatisfaction; no form of label demonstrated any ameliorating effect. In addition, the consequence and informational labels resulted in increased perceived realism and state appearance comparison. Yet more extensive research is required before the effective implementation of any form of label. Copyright © 2018 Elsevier Ltd. All rights reserved.

    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. Copyright © 2010 Elsevier Ltd. All rights reserved.

    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.

    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. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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. Copyright © 2015 Elsevier Ltd. All rights

It was a prospective study that performed a secondary analysis of data from Project “Saúde na Boa”, which included youths attending night classes in secondary public schools in Recife in the state of Pernambuco and Florianópolis in the state of Santa Catarina. Data on the youths’ body type (thinness or excess weight and degree of satisfaction/dissatisfaction with body weight and lifestyle (level of physical activity, participation in physical education classes, sedentary behavior and snacks, soda and alcohol intake were collected at 10 schools from each town (five in the intervention group and five in the control group. The percentages of youths dissatisfied with their body weight were 50.5% and 48.6% at baseline and after intervention, respectively. The percentage of youths with body dissatisfaction due to thinness decreased (21.4% vs. 16.5%, while the percentage of youths with body dissatisfaction due to excess weight increased (29.1% vs. 32.1%. Approximately 41.2% of the youths with body dissatisfaction due to thinness and 18.3% of those dissatisfied due to excess weight became satisfied with their body weight after intervention. The intervention targeting health-related behaviors induced changes in the youths’ degree of satisfaction with their body weight.

Methods: a descriptive, cross-sectional study with 20 obese adolescents of both genders, aged between 10 and 15 years, undergoing treatment at the clinic of endocrinology at Children's Hospital Complex of Sorocaba. Individual interview was conducted according to a pre-determined script of questions and to assess the magnitude of body dissatisfaction was applied to Scale Silhouettes of Stunkard. The interviews we applied the technique of thematic analysis, Minayo. Results: of the 20 adolescents who participated in the study, 11 (55% of males and 9 (45% females and the prevalence of body dissatisfaction was 95%. Most respondents (60% defines obesity as fat, 40% feel different from the other 65% considered normal and feel bad about their body image. Regarding bulliyng, 50% admit they have suffered, and of these, 20% the nickname bothers enough. Conclusion: the occurrence of body dissatisfaction was significant, by suffer bullying and feel uncomfortable with this practice. This study emphasizes the importance that should be given to adolescents obese, the need for an effective food and nutrition education, with actions aimed at changing eating behavior, as well as implement public health policies with intersectoral and multidisciplinary teams to combat the obesity and bullying, which can cause many psychological damage, affecting mental health in adolescence and consequences for life.

    The association between phases of the menstrual cycle and body image was investigated. 44 university women (M age = 23.3 yr., SD = 4.7) judged their perceived and ideal body size, and body dissatisfaction was calculated at each phase of the menstrual cycle, including premenstrual, menstrual, and intermenstrual. Participants selected one of nine figural drawings ranging from very thin to obese that represented their perceived size and ideal size. Body dissatisfaction was measured as the absolute difference between scores on perceived and ideal figural drawings. During each menstrual phase, anthropometric measures of weight, height, body mass index, circumference of waist and abdomen, and body composition were taken. There were no significant differences in any anthropometric measures between the three menstrual cycle phases. Perceived body size and body dissatisfaction were significantly different between menstrual phases, with the largest perceived body size and highest body dissatisfaction occurring during the menstrual phase. Ideal body size did not differ between menstrual phases, although participants desired a significantly smaller ideal size as compared to the perceived size.

    Full Text Available This study investigated if boys and girls who practice exercises with aesthetic propose report higher levels of body dissatisfaction compared to their inactive peers. A total of 199 adolescents (89 boys, mean age 16.1 years, completed measures of body dissatisfaction and psychological commitment to exercise. Results demonstrated that active boys presented lower dissatisfaction than their inactive peers; and active girls were significantly more dissatisfied than inactive ones. Active boys were more satisfied than active girls. The majority of active girls reported a desire for a slimmer silhouette; while active boys were equally divided between those who desired a heavier silhouette and those who were satisfied. Psychological commitment to exercise did not differ between satisfied and dissatisfied active adolescents. Thus, girls who practice aesthetic exercises must be looked at as a high risk population to the development of health harmful behaviors and eating disorders.

    When and why do media-portrayed physically attractive women affect perceivers' self-evaluations? In 6 studies, the authors showed that whether such images affect self-evaluations depends jointly on target features and perceiver features. In Study 1, exposure to a physically attractive target, compared with exposure to an equally attractive model, lowered women's self-evaluations. Study 2 showed that body-dissatisfied women, to a greater extent than body-satisfied women, report that they compare their bodies with other women's bodies. In Study 3, body-dissatisfied women, but not body-satisfied women, were affected by both attractive models and nonmodels. Furthermore, in Study 4, it was body-dissatisfied women, rather than body-satisfied women, who evaluated themselves negatively after exposure to a thin (versus a fat) vase. The authors replicated this result in Study 5 by manipulating, instead of measuring, body dissatisfaction. Finally, Study 6 results suggested that body dissatisfaction increases proneness to social comparison effects because body dissatisfaction increases self-activation. 2007 APA, all rights reserved

    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.

    Background and purpose: Body image dissatisfaction has recently been described as 'normative' for both men and women. Despite intense theoretical interest in a multidimensional concept of male body image, comprehensive models have rarely been assessed empirically. The aim of this study was therefore to examine the relationship between body image and self-esteem among men in a multivariate model. Methods: Participants of this cross-sectional questionnaire study were 239 male university student...

    2013-01-01

    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. Copyright © 2012 Elsevier Ltd. All rights reserved.

    To examine how the associations among body mass index (BMI) and body dissatisfaction and weight and shape concern evolve from late childhood through late adolescence in boys and girls. We analyze data from subjects aged 9-18 years from the Growing Up Today Study, a national prospective cohort of U.S. youth (n = 16,882, yielding 59,750 repeated-measures observations during five waves of data collection). Generalized additive models produced curves of association for body dissatisfaction and weight concern across BMI percentiles. Generalized estimating equations (adjusting for correlated within-subject repeated measures, sibling clusters, pubertal maturation, and region of residence) tested main and interactive effects of BMI, age, and gender. Girls above the 50th BMI percentile reported greater body dissatisfaction than girls below the 50th percentile. By contrast, boys who reported the most body dissatisfaction were either above the 75th BMI percentile (approaching overweight) or below the 10th percentile (approaching underweight). Body dissatisfaction increased with age for both girls and boys, but the gender-specific patterns of BMI effects remained constant. Male and female participants in the overweight/obese BMI range reported the greatest weight concern, but among older adolescents (particularly girls), healthy weight became increasingly associated with greater weight and shape concern. Body dissatisfaction and weight and shape concern intensify across adolescence, but associations between the constructs and BMI remain gender specific. Findings have important implications for eating disorder risk assessment and prevention. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Dunkley, David M.; Masheb, Robin M.; Grilo, Carlos M.

    2010-01-01

    Objective We examined the mediating role of self-criticism in the relation between childhood maltreatment and both depressive symptoms and body dissatisfaction in patients with binge eating disorder (BED). Method Participants were 170 BED patients who completed measures of childhood maltreatment, self-criticism, self-esteem, depressive symptoms, and body dissatisfaction. Results Specific forms of childhood maltreatment (emotional abuse, sexual abuse) were significantly associated with body dissatisfaction. Path analyses demonstrated that self-criticism fully mediated the relation between emotional abuse and both depressive symptoms and body dissatisfaction. Specificity for the mediating role of self-criticism was demonstrated in comparison to other potential mediators (low self-esteem) and alternative competing mediation models. Conclusion These results highlight self-criticism as a potential mechanism through which certain forms of childhood maltreatment may be associated with depressive symptoms and body dissatisfaction in BED patients.

    Full Text Available Abstract: After performing searches in the main scientific articles database, no specific psychometric scale was found that analyzes body dissatisfaction and body checking to athletes. The aim of the study was to analyze the psychometric properties of the Dissatisfaction and Body Checking in Sports Scale (DBCS - male and female versions - in Brazilian athletes. The researchers built the DBCS. Participants were 1,197 athletes. The exploratory factor analysis showed a factor structure that explained more than 40% of the variance in both versions of the DBCS. The results showed a statistically significant relationship between the DBCS - male and female versions - and questionnaires used for concurrent validity (p .05. The findings indicated difference in DBCS scores according to body fat (p = .01. The results showed a positive relationship between DBCS and Eating Attitudes Test scores (p = .001. It was concluded that the DBCS - male and female versions - demonstrated satisfactory concurrent, discriminant, predictive validity and reproducibility.

    van den Berg, Patricia; Thompson, J Kevin

    2007-03-01

    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.

    2008-01-01

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

    Unrealistic weight loss expectations (WLEs) and greater body dissatisfaction may be associated with the poor long-term outcomes of dietary and lifestyle weight loss treatments. We evaluated the association between body size, WLEs and body dissatisfaction in young women attempting to lose weight. Forty-four young healthy women [age range 18-35 years, body mass index (BMI) range 23-40 kg/m2] were recruited. Women were classified as obese (BMI ≥ 30.0 kg/m2) and non-obese (BMI social (career, family acceptance, peer acceptance, mass media, social pressure) factors. Individual WLEs were compared with recommended clinical targets (5%, 10% and 20%) for weight loss. Body dissatisfaction was lower in non-obese subjects and was directly associated with BMI (P media, whereas they perceived that family and friends were supportive of a lesser degree of weight loss. We observed a mismatch between clinical and personal expectations, and social pressure and interpersonal relationships appear to have a prominent role with respect to influencing the association. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    2016-12-01

    This study comprised a systematic review of literature examining empirical relationships between levels of media literacy and body dissatisfaction and disordered eating. The review aimed to integrate research on this topic. Electronic databases were searched for key concepts: media literacy, body dissatisfaction, and disordered eating. Media literacy measures were coded for consistency with media literacy constructs. Sixteen eligible studies were identified. Cross-sectional outcomes depended upon the media literacy construct assessed. Some relationships between high scores on measures consistent with media literacy constructs and low scores on body dissatisfaction and related attitudes were found. Media literacy-based interventions revealed improvements in media literacy constructs realism scepticism, influence of media, and awareness of media motives for profit, and improvements in body-related variables, but not disordered eating. Further research examining relationships between theoretically driven media literacy constructs and body and eating concerns is needed. Recommendations are made for evaluating media literacy-based eating disorder prevention. Copyright © 2016 Elsevier Ltd. All rights reserved.

    We evaluated an attachment theory model in which mother and father care were hypothesized to be indirectly related to body dissatisfaction mediated by attachment anxiety and media internalization. Participants were 232 women diagnosed with an eating disorder who completed a retrospective measure of parental bonds, and measures of attachment anxiety, media internalization, and body image. Mother care was negatively associated with body dissatisfaction, suggesting that recollection of mothers as less caring was directly related to poorer body image. Lower father care, was indirectly associated with greater body dissatisfaction mediated by higher attachment anxiety and higher media internalization. That is, women with an eating disorder who recollected fathers as less caring had higher attachment anxiety, which was related to greater internalizing of media-related thin ideals, that in turn was associated with poorer body image. Mothers and fathers may impact body dissatisfaction by differing mechanisms in clinical samples. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Body dissatisfaction is an important risk and maintaining factor for eating disorders. The aim of the present study was to experimentally test the effects of two emotion regulation strategies - acceptance and rumination - on media-induced body dissatisfaction in eating disorders. After watching pictures of thin models, women with anorexia nervosa (AN; n = 39) and bulimia nervosa (BN; n = 39) were encouraged to either use emotional acceptance or rumination to cope with their feelings. Body dissatisfaction and mood were repeatedly assessed. Acceptance significantly improved body dissatisfaction in women with BN. Rumination led to a significant increase of body dissatisfaction in both eating disorder groups. Results were independent from mood changes. Findings highlight the importance ruminative thinking may have in the aggravation of dissatisfaction with the own body in AN and BN. Results suggest that emotional acceptance is a useful strategy to regulate body dissatisfaction after exposure to thin-ideal media in BN. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To evaluate the influence of self-esteem on levels of body dissatisfaction among adolescent females. 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. The multiple regression model indicated influence of "positive self-esteem" (R(2)=0.16; p=0.001) and "negative self-esteem" (R(2)=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. It was concluded that self-esteem influenced body dissatisfaction in adolescent girls from Juiz de Fora, MG. Copyright © 2014 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    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. Copyright © 2016 Elsevier Ltd. All rights reserved.

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

    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. Copyright © 2013 Elsevier Ltd.

    2001-06-01

    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.

    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. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2011-07-01

    Full Text Available Abstract Background We sought to evaluate the hypothesis that mental health impairment in underweight women, where this occurs, is due to an association between low body weight and elevated levels of body dissatisfaction and/or eating-disordered behaviour. Methods Subgroups of underweight and normal-weight women recruited from a large, general population sample were compared on measures of body dissatisfaction, eating-disordered behaviour and mental health. Results Underweight women had significantly greater impairment in mental health than normal-weight women, even after controlling for between-group differences in demographic characteristics and physical health. However, there was no evidence that higher levels of body dissatisfaction or eating-disordered behaviour accounted for this difference. Rather, underweight women had significantly lower levels of body dissatisfaction and eating-disordered behaviour than normal-weight women. Conclusions The findings suggest that mental health impairment in underweight women, where this occurs, is unlikely to be due to higher levels of body dissatisfaction or eating-disordered behaviour. Rather, lower levels of body dissatisfaction and eating-disordered behaviour among underweight women may counterbalance, to some extent, impairment due to other factors.

    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.

    This brief report tests the mediating effect of self-esteem in the relationship between body dissatisfaction and symptoms of depression and anxiety. A sample of 409 adolescents (females = 58.4%) aged between 14 and 18 years completed the Rosenberg Self-Esteem Scale, the Contour Drawing Rating Scale, the Multidimensional Anxiety Scale for Children, and the Center for Epidemiologic Studies Depression Scale. Overall, results for the indirect effects analysis were significant for both anxiety and depression, which confirmed the mediating role of self-esteem. Thus, a negative perception of one's body image has the effect of lowering self-esteem, which in turn increases psychological distress.

    Purpose To examine how the associations among BMI and body dissatisfaction and weight and shape concern evolve from late childhood through late adolescence in boys and girls. Methods We analyze data from 9–18-year-olds from the Growing Up Today Study, a national prospective cohort of U.S. Youth (n= 16,882, yielding 59,750 repeated measures observations during five waves of data collection). Generalized additive models produced curves of association for body dissatisfaction and weight concern across BMI percentiles. Generalized estimating equations (adjusting for correlated within-subject repeated measures, sibling clusters, pubertal maturation, and region of residence) tested main and interactive effects of BMI, age, and gender. Results Girls above the 50th BMI percentile reported greater body dissatisfaction than girls below the 50th percentile. By contrast, boys who reported the most body dissatisfaction were either above the 75th BMI percentile (approaching overweight) or below the 10th percentile (approaching underweight). Body dissatisfaction increased with age for both girls and boys, but the gender-specific patterns of BMI effects remained constant. Male and female participants in the overweight/obese BMI range reported the greatest weight concern, but among older adolescents (particularly girls), healthy weight became increasingly associated with greater weight and shape concern. Conclusions Body dissatisfaction and weight and shape concern intensify across adolescence, but associations between the constructs and BMI remain gender-specific. Findings have important implications for eating disorder risk assessment and prevention. PMID:23084175

    Although Islam is the fastest growing religion worldwide, only few studies have investigated body image in Muslim women, and no study has investigated body checking. Therefore, the present study examined whether body image, body checking, and disordered eating differ between veiled and unveiled Muslim women, Christian women, and atheist women. While the groups did not differ regarding body dissatisfaction, unveiled Muslim women reported more checking than veiled Muslim and Christian women, and higher bulimia scores than Christian. Thus, prevention against eating disorders should integrate all women, irrespective of religious affiliation or veiling, with a particular focus on unveiled Muslim women.

    Previous research suggests that parental divorce moderates genetic influences on body dissatisfaction. Specifically, the heritability of body dissatisfaction is higher in children of divorced versus intact families, suggesting possible gene-environment interaction effects. However, prior research is limited to a single, self-reported measure of body dissatisfaction. The primary aim of this study was to examine whether these findings extend to a different dimension of body dissatisfaction: body image perceptions. Participants were 1,534 female twins from the Minnesota Twin Family Study, aged 16-20 years. The Body Rating Scale (BRS) was used to assess body image perceptions. Although BRS scores were heritable in twins from divorced and intact families, the heritability estimates in the divorced group were not significantly greater than estimates in the intact group. However, there were differences in nonshared environmental effects, where the magnitude of these environmental influences was larger in the divorced as compared with the intact families. Different dimensions of body dissatisfaction (i.e., negative self-evaluation versus body image perceptions) may interact with environmental risk, such as parental divorce, in discrete ways. Future research should examine this possibility and explore differential gene-environment interactions using diverse measures. © 2015 Wiley Periodicals, Inc.

    This experimental study examined whether a brief video intervention identifying the artificial nature of media images could protect adolescent girls from negative media exposure effects and body dissatisfaction. A 2 (intervention condition)×2 (exposure condition) between-groups design was used. Participants were 127 British girls aged between 10 and 13 recruited from two secondary schools. Girls were assigned to one of four experimental conditions. An intervention video was shown to half of the girls immediately before they viewed ultra-thin models or control images. The video was developed by Dove's Self-Esteem Fund and has the benefits of being professionally produced and freely available through the Internet. In the absence of the intervention video, viewing thin idealized models was associated with lower state body satisfaction and lower state body esteem than exposure to control images. However, viewing the video intervention immediately before exposure prevented this negative exposure effect. The results suggest that, in the short term, this widely available video prevents girls from making damaging social comparisons with media models. Although this study only examined short-term effects, the findings add to the growing evidence that media literacy interventions may be useful tools in protecting young girls from body dissatisfaction. ©2010 The British Psychological Society.

    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.

    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.

    Full Text Available The purpose of this study was to assess if perfectionism components explained body dissatisfaction (BD, sociocultural influences of aesthetic model (SIAM and symptoms of eating disorders (ED. The sample comprised 30 women with Bulimia Nervosa (BN, 35 women with Eating Disorder not Otherwise Specified (EDNOS and 63 women without ED. A regression analysis showed that concern over mistakes (CM and doubt about actions explained BD and SIAM in the BN sample; while concern over mistakes only explained SIAM in the EDNOS sample. These findings evidence that two perfectionism components contribute to vulnerability of thinness ideal and BD among women, which constitute two important risk factors for ED.

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

    Social media has been associated with body dissatisfaction and eating disorder symptoms among young women and adolescent girls. However, despite notable evidence of susceptibility to body image pressures, it remains unknown whether these associations generalize to sexual minority men. A nationwide sample of 2,733 sexual minority men completed an online survey advertised to Australian and New Zealand users of a popular dating app. Participants answered questions about how frequently they used 11 different social media platforms in addition to questions about their dating app use, body image, eating disorder symptoms, and anabolic steroids. Facebook, Youtube, Instagram, and Snapchat were the most frequently used social media platforms. A pattern of small-sized and positive associations emerged between social media use and body dissatisfaction, eating disorder symptoms, and thoughts about using anabolic steroids. Facebook, Instagram, and Snapchat evidenced the strongest associations. The associations of social media use with both muscularity dissatisfaction and eating disorder symptoms were stronger for image-centric social media platforms (e.g., Instagram) than nonimage-centric platforms (e.g., Wordpress); no differences were observed for body fat dissatisfaction, height dissatisfaction, or thoughts about using anabolic steroids. Previously documented associations of social media use with body dissatisfaction and related variables among women and girls appear to generalize to sexual minority men. Social media platforms that more centrally involve imagery may be of greater concern than nonimage-centric platforms. Additional research with sexual minority men is needed to elucidate the distinctions between adaptive and maladaptive social media use in the context of body dissatisfaction, eating disorders, and anabolic steroid use.

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

    The perception of one's body image becomes particularly important in adolescence. Body dissatisfaction has been associated with negative psychological functioning, such as self-esteem and depression. Previous findings showed that the decreased self-esteem due to body dissatisfaction explained the association between negative attitude toward body and psychological well-being in different cultural contexts. The present study examined adolescents from the US (N = 1002) and Korea (N = 3993) and replicated and extended the previous findings regarding body dissatisfaction and associated psychological outcomes. The results showed that body dissatisfaction predicted higher depressed mood and that self-esteem mediated this association for both American and Korean adolescents. Notably, the indirect effect of body dissatisfaction and perceived body image on depressed mood via self-esteem was greater for American adolescents than for Korean adolescents. The implications of the cultural difference in the significance of self-esteem in mediating the body dissatisfaction and depressed mood are discussed.

    Full Text Available Background: Body dissatisfaction has been identified as a psychological correlate of obesity that is related to disordered eating, poor self-esteem, and depression. However, not all individuals with obesity are equally vulnerable to these correlates, and ‘normative discontent' is present in individuals with normal weight, too. In this light, the complex relationship of body image and individual weight status seems like a worthwhile direction of research inquiry. As such, this review aims to systematically explore the degree of body dissatisfaction in individuals with obesity compared to normal-weight individuals. Methods: A systematic literature search was conducted. All quantitative studies of adult samples reporting results regarding differences in body dissatisfaction between individuals with normal weight and obesity were included. Results: 17 articles were found. Across studies, individuals with obesity reported higher body dissatisfaction than normal-weight individuals (questionnaires: d = 0.89, 95% CI = 0.63-1.16, p Conclusion: The findings underline the severity of body dissatisfaction among individuals with obesity and especially among women. Future research recommendations are discussed.

    Body dissatisfaction is a common problem among adolescent girls that is linked to serious outcomes, including the development of eating disorders. This study tested to what degree five theorized risk factors (weight-related teasing, thin-ideal internalization, body mass index [BMI], self-esteem, and perfectionism) predicted prospective changes in body dissatisfaction. At baseline, 393 10th and 11th grade girls (M=15.8 years) completed questionnaires and had their height and weight measured. One year later, 316 participants' body dissatisfaction was reassessed (80.4% retention). Results suggested that self-esteem was the most potent risk factor, followed by BMI, when used to categorize girls into high- and low-risk groups for body dissatisfaction at follow-up. However, weight-related teasing, thin-ideal internalization, and perfectionism did not prove to be risk factors. These results suggest self-esteem and BMI are relevant variables for helping to identify middle-adolescent girls who may be at risk for subsequent increases in body dissatisfaction.

    Maladaptive patterns of social networking site (SNS) use, such as excessive reassurance seeking, are associated with body dissatisfaction and disordered eating. However, it is unclear how these processes play out among different racial groups. This study examined racial differences in SNS use and body dissatisfaction and disordered eating. Black (n=445) and White (n=477) female undergraduates completed online measures of SNS use (frequency and reassurance seeking), body dissatisfaction, and disordered eating. Black women reported less body dissatisfaction, marginally less disordered eating, and less frequent Facebook use than White women; there were no race differences in SNS reassurance seeking. More frequent Facebook use was associated with more body dissatisfaction (but not disordered eating), and more SNS reassurance seeking predicted both more body dissatisfaction and disordered eating. Associations were not moderated by race, suggesting maladaptive SNS use may have negative consequences for both Black and White women. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Background The study of male body image has increased substantially, but there are few assessment tools available for this population. The Male Body Dissatisfaction Scale (MBDS has been widely used among students to research body image disturbances and eating disorders. However, the psychometric properties of this instrument have not been tested in the Brazilian context.Objectives To explore the psychometric properties (convergent validity, internal consistency, test-retest reliability and factor structure of the Brazilian version of the MBDS.Methods Two-hundred sixty-four undergraduate students were evaluated. Pearson’s correlation was used to test the convergent validity of the MBDS and the Drive for Muscularity Scale, the Swansea Muscularity Attitudes Questionnaire, the Rosenberg Self-Esteem Scale, the Beck Depression Inventory, the Eating Attitudes Test-26, and the Commitment to Exercise Scale. Test-retest reliability was evaluated using t-tests for repeated measures and by calculating the coefficient of intraclass correlation. Exploratory factor analysis was conducted, and Cronbach’s α coefficients were determined. A significance level of 5% was adopted.Results The MBDS had an adequate factor structure, with two factors explaining 52.67% of the total variance. It showed excellent internal consistency (Cronbach’s α between 0.90 and 0.92, a high intraclass correlation coefficient (0.81, and convergent validity with the drive for muscularity, the psychological commitment to exercise, low self-esteem, and eating disorder risk behaviour measures.Discussion The MBDS appears to be a valid and reliable tool for evaluating Brazilian male body image dissatisfaction.

    Full Text Available 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 nonpractitioners group.

    2018-01-01

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

    2016-03-01

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

    Full Text Available ABSTRACT Objective Social anxiety disorder (SAD and body image dissatisfaction (BID are common problems among college students, but few studies focused on medical students. We aimed to estimate the prevalence, severity and correlates of SAD symptoms and BID among medical students of a Brazilian public university. Methods A cross-sectional study with 479 students, using structured instruments: Social Phobia Inventory (SPIN, Body Shape Questionnaire (BSQ, and Beck Depression Inventory (BDI. Bivariate analyses were followed by logistic regression models to obtain independent predictors of SAD symptoms, BID and both outcomes combined. Results Most students were single (99% and female (58.7%. The prevalence rates of SAD symptoms (SPIN ≥ 19 and BID (BSQ ≥ 81 were 36.3% and 34.7%, respectively. Depressive symptoms (BDI ≥ 19 occurred in 8.8% of the sample. SAD symptoms were independently associated with: BID, thoughts of abandoning the course, difficulty making friends, depressive symptoms, and mental health treatment prior to university. Besides SAD symptoms, BID was associated with female sex, difficulty making friends, depressive symptoms, and body mass index (BMI. Seventy-eight students (16.3% presented SAD symptoms and BID, which was associated with female sex, difficulty making friends, dissatisfaction with the course, depressive symptoms and BMI. Conclusion SAD symptoms and BID are common and related problems that should be screened for among medical students. The identification of specific correlates could contribute to the elaboration of preventive measures, minimizing the distress and negative impact of these mental health problems on relationships and academic performance.

    In the transition from early to mid-adolescence, gender differences in pubertal development become significant. Body dissatisfaction is often associated with body mass, low self-esteem and abnormal eating habits. The majority of studies investigating body dissatisfaction and its associations have been conducted on female populations. However, some evidence suggests that males also suffer from these problems and that gender differences might already be observed in adolescence. To examine body dissatisfaction and its relationship with body mass, as well as self-esteem and eating habits, in girls and boys in transition from early to mid-adolescence. School nurses recorded the heights and weights of 659 girls and 711 boys with a mean age of 14.5 years. The Rosenberg Self-Esteem Scale and the Body Dissatisfaction subscale of the Eating Disorder Inventory were used as self-appraisal scales. Eating data were self-reported. The girls were less satisfied with their bodies than boys were with theirs (mean score (SD): 30.6 (SD 12.2) vs. 18.9 (SD 9.5); p eating habits were less satisfied with their bodies than those describing normal eating habits (mean (SD): 33.0 (12.9) vs. 21.2 (10.2); p eating habits revealed a significant relationship with body dissatisfaction in the transitional phase from early to mid-adolescence in girls and boys, but significant gender differences were also found.

    The current study the relationship between eating disorders (EDs) and suicidal ideation and suicide attempt in adult inpatients. In particular, the present study investigated one potential mechanism, body dissatisfaction (BD), which may contribute to increased risk for suicide in adult ED patients. A sample of 432 psychiatric inpatients ranging from 18 to 65 years of age participated in the current study. Findings indicated that patients who have higher levels of BD also had higher levels of passive and active suicidal ideation and previous suicide attempts. Higher levels of BD were also related to increased suicidal ideation after controlling for depression and emotion dysregulation. Although additional risk factors for suicide should be investigated in adults with EDs, this study provides evidence regarding the relationship between BD and risk for suicide ideation and attempt.

    This study demonstrates the substantial conceptual consequences in distinguishing a variable's role as a moderator as opposed to a mediator. In particular, the study investigates the role of dietary restraint in the relationship between body dissatisfaction and psychological well-being. Path analyses showed that, in addition to its mediating role, dietary restraint has a moderating role, such that there is a stronger relationship between body dissatisfaction and psychological well-being when dietary restraint is high than when dietary restraint is low. In contrast, gender had only a direct effect on weight dissatisfaction. It was concluded that the same processes occur for both men and for women, whereby it is the individuals who diet who suffer loss of psychological well-being.

    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. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT-26 and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

    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.

    This pilot study evaluated a body image intervention for men, Body Project M. Seventy-four British undergraduate men took part in two 90-min intervention sessions, and completed standardised assessments of body image, bulimic pathology, and related outcomes at baseline, post-intervention, and 3-month follow-up. Fifty-three other men completed the questionnaires as an assessment-only control group. Per-protocol analysis showed that Body Project M improved men's dissatisfaction with body fat and muscularity, body appreciation, muscularity enhancing behaviours, appearance comparisons, and internalization (ds=0.46-0.80) at post-intervention. All except dissatisfaction with muscularity and internalization were sustained at 3-month follow-up. No effects were found for bulimic pathology. Post-intervention effects for dissatisfaction with muscularity and internalization only were retained under intention-to-treat analysis. Participants were favourable towards the intervention. This study provides preliminary evidence for the acceptability and post-intervention efficacy of Body Project M. Further development of the intervention is required to improve and sustain effects.

    The goal of the present study was to assess the role of body dissatisfaction and socio-cultural factors on eating psychopathology in women with Binge Eating Disorder (BED) and women without BED. Seventy obese women consecutively evaluated participated: 35 with BED and 35 without BED who attended for the first time in a weight loss program. All participants completed a battery of questionnaires, including: Body Shape Questionnaire, Questionnaire of Influences on the Aesthetic Body Shape Model, Questionnaire on Eating and Weight Patterns, Three Factor Eating Questionnaire, and they were interviewed with the Interview for the Diagnosis of Eating Disorder-IV. The Body Mass Index, Waist-to-Hip Ratio and Body Fat were calculated. The results showed that 21% of obese women who participated in a weight reduction program met BED criteria. The scores of body dissatisfaction, influences of socio-cultural factors and eating psychopathology were higher in women with BED compared with women without BED. In the same way, significantly stronger correlations were found among influences of socio-cultural factors, specifically, influence of advertisement, social relations and eating psychopathology in women with BED than women without BED. It is concluded that the high body dissatisfaction as well as stronger associations among influence of socio-cultural factors and eating psychopathology could play an important role in women with BED.

    Social media engagement by adolescent girls is high. Despite its appeal, there are potential negative consequences for body dissatisfaction and disordered eating from social media use. This study aimed to examine, in a cross-sectional design, the relationship between social media use in general, and social media activities related to taking "selfies" and sharing specifically, with overvaluation of shape and weight, body dissatisfaction, and dietary restraint. Participants were 101 grade seven girls (M(age)  = 13.1, SD = 0.3), who completed self-report questionnaires of social media use and body-related and eating concerns measures. Results showed that girls who regularly shared self-images on social media, relative to those who did not, reported significantly higher overvaluation of shape and weight, body dissatisfaction, dietary restraint, and internalization of the thin ideal. In addition, among girls who shared photos of themselves on social media, higher engagement in manipulation of and investment in these photos, but not higher media exposure, were associated with greater body-related and eating concerns, including after accounting for media use and internalization of the thin ideal. Although cross-sectional, these findings suggest the importance of social media activities for body-related and eating concerns as well as potential avenues for targeted social-media-based intervention. © 2015 Wiley Periodicals, Inc.

    We examined longitudinal associations between weight dissatisfaction, weight changes, anorexia of aging, and obesity among 1,793 seniors followed over 4 years between 2003 and 2009. Obesity prevalence (body mass index [BMI] ≥ 30) and prevalence/incidence of weight dissatisfaction, anorexia of aging (self-reported appetite loss), and weight changes ≥5% were assessed. Predictors of weight loss ≥5%, anorexia of aging, and weight dissatisfaction were examined using logistic regressions. Half of seniors experienced weight dissatisfaction (50.6%, 95% confidence interval [CI] = [48.1, 53.1]). Anorexia of aging and obesity prevalence was 7.0% (95% CI = [5.7, 8.3]) and 25.1% (95% CI = [22.9, 27.3]), whereas incidence of weight gain/loss ≥5% was 6.6% (95% CI = [1.3, 11.9]) and 8.8% (95% CI = [3.3, 14.3]). Weight gain ≥5% predicts men's subsequent weight dissatisfaction (odds ratio [OR] = 6.66, 95% CI = [2.06, 21.60]). No other association was observed. Weight dissatisfaction is frequent but not associated with subsequent eating disorders. In men, weight gain predicted weight dissatisfaction. Seniors' weight dissatisfaction does not necessarily equate weight changes. Due to its high prevalence, it is of public health interest to understand how seniors' weight dissatisfaction may impact health. © The Author(s) 2014.

    Body image dissatisfaction has been linked to belonging to the gay community and poor self-esteem among gay men. This study was designed to explore the applicability of a moderation model and a mediation model in explaining the relations between sense of belonging to the gay community, body image dissatisfaction and self-esteem among 90 self-identified Australian gay men. Participants completed the psychological subscale of the Sense of Belonging Instrument, the Body Satisfaction Scale, and the Rosenberg Self-Esteem Scale. Results supported the moderation model; the relation between body image dissatisfaction and self-esteem was found to be statistically significant only at average and high levels of belonging to the gay community. The mediation model was also supported; body image dissatisfaction partially mediated the sense of belonging-self-esteem relation. Educating gay men and health professionals about the possible negative outcomes of "belonging" to an appearance-oriented community is important.

    Recent research suggests Internet exposure, including Facebook use, is positively correlated with body dissatisfaction, especially among girls and young women. Canada has one of the highest Internet access rates in the world, yet no previous study has examined this relationship using nationally representative data. Our objective was to evaluate the relationship between Internet use and body dissatisfaction among a national, population-based sample of Canadian females 12-29 years of age. We used cross-sectional data from the Canadian Community Health Survey 2011-2012. Body dissatisfaction was measured using a 5-point Likert scale and defined as "very dissatisfied/dissatisfied" with one's body. The explanatory variable was time spent using the Internet per week in the past 3 months, ranging from none/20 hours. We used multinomial logistic regression to investigate whether greater Internet use was associated with increasing odds of being very dissatisfied/dissatisfied, neutral, or satisfied with one's body, using very satisfied as the referent. Probability survey sampling weights were applied to all analyses. Of 2983 included participants, sampled to represent 940,786 young Canadian females, most were 20-29 years old (61.98%) and living in households with an annual income Can $80,000 or more (44.61%). The prevalence of body dissatisfaction was 14.70%, and 25- to 29-year-olds were more likely than 12- to 14-year-olds to be very dissatisfied or dissatisfied with their body (20.76% vs 6.34%). Few (5.01%) reported none/Internet use, over half (56.93%) reported 1-10 hours, and one-fifth (19.52%) reported spending >20 hours online per week. Adjusting for age and income, the odds of being very dissatisfied/dissatisfied, relative to very satisfied, were greater in the highest versus lowest Internet use group (adjusted odds ratio [AOR] 3.03, 95% CI 1.19-7.70). The AORs for this level of body dissatisfaction increased across increasing levels of Internet use, ranging from 0

    This study investigated whether the association between body image dissatisfaction and poor self-rated health is mediated by insufficient physical activity and unhealthy eating habits. The participants were 6727 men and 8037 women from the baseline (2008–2010) of the Longitudinal Study of Adult Health (Estudo Longitudinal de Saúde do Adulto, ELSA-Brasil). Structural equation modelling was used. Associations were found between body image dissatisfaction and poor self-rated health in both sexes. Insufficient physical activity was a mediator. However, unhealthy eating habits were found to exert a mediator effect only via insufficient physical activity. Body image dissatisfaction was found to associate, both directly and possibly indirectly, with poor self-rated health, mediated by insufficient physical activity and unhealthy eating habits. Accordingly, encouraging physical activity and healthy eating can contribute to reducing body image dissatisfaction and favour better self-rated health.

    Researchers have investigated the efficacy of a gratitude intervention for decreasing body dissatisfaction (BD) in an internet treatment-seeking sample and demonstrated it worked equally well to decrease BD as cognitive restructuring. We extend this research by testing the efficacy of a gratitude intervention on BD, along with common sequelae of BD: dysfunctional eating, negative mood, and depressive symptoms. Females were randomly assigned to Gratitude, Cognitive Restructuring, or Control conditions. Pre- to post-intervention period comparisons found the gratitude intervention to perform better than the other conditions at increasing body esteem, decreasing BD, reducing dysfunctional eating, and reducing depressive symptoms.

    Full Text Available Abstract Background Body shape dissatisfaction has been thought to have an indispensable impact on weight control behaviors. We investigated the prevalence of body shape dissatisfaction (BSD and explored its association with weight status, education level and other determinants among young adults in Hong Kong. Methods Information on anthropometry, BSD, and socio-demographics was collected from a random sample of 1205 young adults (611 men and 594 women aged 18-27 in a community-based household survey. BSD was defined as a discrepancy between current and ideal body shape based on a figure rating scale. Cross-tabulations, homogeneity tests and logistic regression models were applied. Results The percentages of underweight men and women were 16.5% and 34.9% respectively, and the corresponding percentages of being overweight or obese were 26.7% and 13.2% for men and women respectively. Three-quarters of young adults had BSD. Among women, 30.9% of those underweight and 75.5% of those with normal weight desired a slimmer body shape. Overweight men and underweight women with lower education level were more likely to have a mismatch between weight status and BSD than those with higher education level. After controlling for other determinants, underweight women were found to have a higher likelihood to maintain their current body shapes than other women. Men were found to be less likely to have a mismatch between weight status and BSD than women. Conclusions Overweight and obesity in men and underweight in women were prevalent among Hong Kong young adults. Inappropriate body shape desire might predispose individuals to unhealthy weight loss or gain behaviors. Careful consideration of actual weight status in body shape desire is needed in health promotion and education, especially for underweight and normal weight women and those with a low education level.

    The thin-ideal of feminine beauty has a strong impact on body image and plays a central part in eating disorders. This ideal is widely promoted by the media images that flood western societies. Although the harmful effects of exposure to thin-ideal media images have been repeatedly demonstrated experimentally in English-speaking western countries, no such studies exist in southern Europe. There is evidence to suggest that the use of average-size models could reduce these negative effects. This study investigates body image amongst French and Italian students following exposure to media images of thin or average-size models, with a neutral or supportive slogan. The data were gathered in three locations: the psychology departments of the Universities of Padua, Italy, and Toulouse, France, and lastly high schools in the Toulouse area. A total of 299 girls took part in the study; their average age was 19.9 years old (S.D.=2.54) In order to investigate the effects of media images, we created three fake advertisements, allegedly promoting body-cream. The first advertisement displayed an ideally-thin model accompanied by a neutral slogan. In the second, the model was average-size with the same neutral slogan. The last advertisement also contained the average-size model, but with a supportive slogan designed to convey acceptance of deviations from the social norms of thinness. The participants first graded themselves on a VAS of body dissatisfaction (0 to 10). On the basis of this score, we created a first group containing girls reporting body dissatisfaction (VAS>or=5), the second with those reporting no body dissatisfaction (VASnegative effects of exposure to thin-ideal media images among students with body dissatisfaction. The use of average-size models in the media and advertising might help reduce these effects. No improvement was obtained via the use of a supportive slogan. These results highlight the importance of media literacy campaigns in the prevention of eating

Cross-sectional analysis using data from a large, population-based study of adolescents participating in Eating and Activity in Teens, 2010 (EAT 2010) (N = 2,793; Mage = 14.4 years). The sample was socioeconomically and racially/ethnically diverse (81% racial/ethnic minority; 54% low or low-middle income). Body dissatisfaction differed significantly across racial/ethnic groups; Asian American girls and boys reported the most dissatisfaction with their bodies. Among boys, the relationship between body dissatisfaction and unhealthy weight control behaviors was moderated by race/ethnicity (p psychological well-being interacted significantly with adolescents' racial/ethnic backgrounds (with the exception of girls' self-esteem). Findings highlight specific racial/ethnic differences in the associations between body dissatisfaction and psychological well-being, and underscore the importance of addressing body dissatisfaction in youth of all racial/ethnic backgrounds.

    Full Text Available Body dissatisfaction has been related to low self-esteem and depression in adolescents. With regard to the current world wide rise in childhood obesity and common stigmatization of adults and children with obesity, easy to use and cost effective measurements of body dissatisfaction would be helpful in epidemiological research. In the current study, detailed data on body measurements with regard to perceived and ideal body size and body dissatisfaction, as measured with the figure preference task, are presented for a population based sample of 3837 children. Perceived body size correlations to weight, body mass index [BMI], and waist circumference were between 0.41 and 0.54; and to height between 0.12 and 0.21. Odds ratios for lower self-esteem increased with increase in body dissatisfaction. Gender differences in body dissatisfaction were present but not found in relation to self-esteem. It is concluded that the figure preference task yields valuable information in epidemiological studies of children as young as 7.5 years of age. It is argued, that the figure preference task is an additional measurement which theoretically relates to psychological stress in childhood.

    Full Text Available Body dissatisfaction has been related to low self-esteem and depression in adolescents. With regard to the current world wide rise in childhood obesity and common stigmatization of adults and children with obesity, easy to use and cost effective measurements of body dissatisfaction would be helpful in epidemiological research. In the current study, detailed data on body measurements with regard to perceived and ideal body size and body dissatisfaction, as measured with the figure preference task, are presented for a population based sample of 3837 children. Perceived body size correlations to weight, body mass index [BMI], and waist circumference were between 0.41 and 0.54; and to height between 0.12 and 0.21. Odds ratios for lower self-esteem increased with increase in body dissatisfaction. Gender differences in body dissatisfaction were present but not found in relation to self-esteem. It is concluded that the figure preference task yields valuable information in epidemiological studies of children as young as 7.5 years of age. It is argued, that the figure preference task is an additional measurement which theoretically relates to psychological stress in childhood.

    The present study aimed to compare body dissatisfaction, food choices, physical activity and weight-management practices by gender and school type. A questionnaire was used to obtain height, weight, body image perception using Stunkard's figure rating scale, food choices, physical activity and weight-management practices. Nine single- and mixed-gender schools located in Bangkok Metropolitan Region, Thailand. Students in 10th-12th grade, aged 15-18 years (n 2082). Only 18% of females and 21% of males did not indicate body dissatisfaction. About 66% of females selected a thinner ideal figure than their current figure. Among males, 44% wanted a thinner figure, but 35% wanted a bigger figure. However, univariate analysis found differences by school type but not gender in the degree of body dissatisfaction; students in single-gender schools had more body dissatisfaction. Females reported using more weight-management practices but less physical activity, while males reported healthier food choices. Participants in single-gender schools had healthier food choices compared with those in mixed-gender schools. Adolescents who were at increased risk of a greater degree of body dissatisfaction were females, attended single-gender schools, had lower household income, higher BMI and less physical activity. Most participants reported being dissatisfied with their current body shape, but the type and level of dissatisfaction and use of weight-management practices differed by gender and type of school. These findings suggest that programmes to combat body dissatisfaction should address different risk factors in males and females attending single- and mixed-gender schools.

    Obsession with thinness and body dissatisfaction can lead adolescents to follow unsupervised diets, which could result in risky weight control behaviors such as fasting, vomiting, use of diuretics and laxatives. The aim of the current study is to examine weight control behaviors in dieting adolescents and relate them to body dissatisfaction (BD) and obsession with thinness (OT). A cross-sectional study was conducted on 439 adolescents from Valparaiso public schools to investigate risky weight control behaviors due to BD and OT scales from the Eating Disorders Inventory-2 (EDI-2), comparing restrained eaters and non-restrained eaters. A total of 43% adolescents had followed a weight loss diet without medical supervision. The dieters had higher BD and OT values. Moderate to severe food restriction, based on expert judgment, was observed in 29.6%, and differences in the presence and severity of purging behaviors were found between the 2 groups. One third of the adolescents studied followed diets without professional supervision and had higher BD and OT values, as well as risky weight control behaviors. Overweight and obese adolescents followed more restrictive diets and developed riskier weight control behaviors. Copyright © 2015. Publicado por Elsevier España, S.L.U.

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

    2013-09-01

    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.

    This study aimed to identify cultural-level variables that may influence the extent to which adolescents from different cultural groups are dissatisfied with their bodies. A sample of 1730 male and 2000 female adolescents from Australia, Fiji, Malaysia, Tonga, Tongans in New Zealand, China, Chile, and Greece completed measures of body satisfaction, and the sociocultural influences on body image and body change questionnaire, and self-reported height and weight. Country gross domestic product and national obesity were recorded using global databases. Prevalence of obesity/overweight and cultural endorsement of appearance standards explained variance in individual-level body dissatisfaction (BD) scores, even after controlling for the influence of individual differences in body mass index and internalization of appearance standards. Cultural-level variables may account for the development of adolescent BD.

Boys were more likely to wish to increase the size of their body silhouette (26.4% while girls wished to reduce theirs (52.4%. Adolescents from urban areas manifested greater prevalence of BI dissatisfaction and were more likely to want to reduce their body silhouette. The reasons given by these adolescents for why they were dissatisfied with their body images were similar for both sexes (p = 0.156. When analyzed by neighborhood the urban adolescents said that their dissatisfaction was esthetic, whereas the rural adolescents said it was based on self-esteem. An association was detected between perceived BI and the reasons for dissatisfaction. Conclusions: Esthetics, self-esteem and health were the most common reasons for BI dissatisfaction among these adolescents. More than half of them were dissatisfied with their body silhouettes. Therefore, there is a need for interventions by health services and professionals in this age range in order to avoid possible future problems with eating disorders (anorexia, bulimia and vigorexia.

The study also examines celebrity involvement as an antecedent of the outcome variables. Data were collected through a survey of 1,059 adolescents in Singapore. Regression analyses indicate that SNSs use was related to adolescents’ BID. Specifically, social comparison with friends on SNSs was significantly associated with adolescents’ BID, DT, and DM. Gender differences were also observed—social comparison with celebrities was significantly associated with BID and DT among female adolescents. Celebrity involvement was significantly associated with male BID. Theoretical and practical implications were discussed.

    The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and socioeconomic status (SES). We also examined the association longitudinally. A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11-18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants were resurveyed through mails 5 years later (Time, 2; N = 2,516). The relationship between body dissatisfaction and self-esteem was strong and significant in both boys and girls (all p values p = .16), or between the middle school and high school cohorts in either boys (p = .79) or girls (p = .80). Among girls, the relationship between body dissatisfaction and self-esteem was strong, but did vary across weight status, race/ethnicity, and SES (all p values = .0001-.03). The relationship was nonsignificant in underweight girls (p = .36), and weaker but still significant among black, Asian, and low SES group girls (all p values p values = .18-.79). In longitudinal analyses, the strength of the association did not change significantly as adolescents grew older. Findings indicate that body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages.

    This study aims to examine the association of body image and weight perceptions with risk of depression and suicidal attempts in Jamaican adolescents with sickle cell disease (SCD). Adolescents with SCD and a national sample of Jamaican adolescents completed a questionnaire examining body image, weight perceptions, and risk for depression. Perceived and desired body images were similar for both groups. Adolescents with SCD had higher levels of "negative body satisfaction" (43.9% vs. 33.9%; P = 0.03), risk for depression (28.7% vs. 19.3%; P = 0.01), and attempted suicide (12.4% vs. 6.6%; P = 0.02) than national sample. Risk of depression was higher in those who perceived themselves to be over or underweight, and lower in those with more friends and attending school. Females and those with body image dissatisfaction were more likely to have attempted suicide. Within the SCD adolescents, girls were at greater odds of having mental health issues. Jamaican adolescents with SCD have significantly higher rates of negative body satisfaction and depressive symptoms, and nearly twice the rate of attempted suicide, compared with their healthy peers. This underscores the need for healthcare professionals to better explore and discuss healthy weight, body satisfaction, and coping with the demands and uncertainties of having a chronic illness with Jamaican adolescents with SCD, even while promoting body acceptance and good self-esteem. Screening for mood disorders is strongly recommended and gender-specific interventions should be developed. Healthcare professionals need to encourage positive social interactions that improve adolescents' mental health. © 2016 Wiley Periodicals, Inc.

    Being overweight and having negative self-perceptions (body dissatisfaction) can have problematic consequences for adolescents physically, socially, and psychologically. Understanding associations between weight, self-perceptions, and peer experiences across ethnicities is particularly important given recent increases in obesity among ethnic minorities. The current study aimed to address these issues by examining Body Mass Index (BMI) z-scores and body dissatisfaction predicting change in general self-worth over time via peer victimization experiences in a diverse sample of 236 youth (ages 10-16 years). Body dissatisfaction predicted decreases in self-worth over time even after controlling for BMI z-score. BMI z-scores predicted decreases in self-worth over time only for white adolescents, whereas body dissatisfaction directly predicted decreases in self-worth for African American youth and indirectly via peer victimization for white youth. Associations were also considered by gender. Implications for intervention efforts for both white and African American adolescents are discussed.

    We examined two hypotheses regarding the potential association of pornography use with body image-related and eating disorder-related psychopathology among sexual minority males (i.e. non-heterosexual males). Our primary hypothesis was that pornography use would be associated with males' body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life impairment; our secondary hypothesis was that the type of pornography, namely, professional versus amateur pornography, which contains idealised and non-idealised (i.e. regular) bodies, respectively, would moderate these associations. A sample of 2733 sexual minority males living in Australia and New Zealand completed an online survey that contained measures of pornography use, body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life. Almost all (98.2%) participants reported pornography use with a median use of 5.33 hours per month. Multivariate analyses revealed that increased pornography use was associated with greater dissatisfaction with muscularity, body fat and height; greater eating disorder symptoms; more frequent thoughts about using anabolic steroids; and lower quality of life. Effect sizes for these associations were uniformly small. Neither relationship status nor genital dissatisfaction was associated with pornography use. The association between pornography use and thoughts about using anabolic steroids was stronger for viewers of professional pornography than viewers of amateur pornography. The findings suggest that the use of pornography is weakly associated with body dissatisfaction and related variables and that the type of pornography (amateur vs professional) viewed may be a moderating factor in some cases. Within the limits of a cross-sectional study design, these findings may have implications for clinicians who treat individuals with eating disorders, body dysmorphic disorder, anabolic-androgenic steroid

    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. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    The purpose of the present study was to investigate the association between Body Mass Index, suicide, perceived stress, and life dissatisfaction in a general population sample of Korean adults. A total of 6,022 nationally representative adults aged 18 to 74 were selected using a multistage cross-sectional cluster sampling method. Questionnaires regarding suicide behaviors, perceived stress, and life satisfaction were completed by the participants. They also reported their heights and weights, which were used to calculate BMI. Psychiatric disorders were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, using the Korean version of the Composite International Diagnostic Interview. The results showed that being underweight was associated with higher risk for suicide ideation [odds ratio (OR), 1.6; 95% confidence interval (Cl), 1.18-2.05] and suicide attempt (OR, 2.0, 95% Cl, 1.23-3.31). Likewise, obesity also increased the risk of suicide ideation (OR, 1.3; 95% Cl, 1.11-1.56) although not suicide attempt. Furthermore, underweight individuals were more likely to report severe level of perceived stress (OR, 1.7; 95% Cl, 1.26-2.17) and life dissatisfaction (OR, 1.3; 95% Cl, 1.07-1.68). All of the results remained significant after adjusting for age, gender, education, and psychiatric illnesses. This study found that being underweight is a significant risk factor for suicide and poor subjective wellbeing in Korea. It suggests that BMI status may be an important modifiable factor for improving mental health in Korea.

    2011-03-01

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

    The aim of this study was to examine the relationships between gender and the educational grade on the one hand, and physical activity levels, motivation, self-identity, body dissatisfaction, the intention to be physically active and daily sitting time on the other, in a sample of Spanish high school adolescents. The sample consisted of 2087 Spanish students from the 3rd (n = 1141) and 4th grade (n = 946), both male (n = 1046) and female (n = 1041), ranging in age from 15 to 17 years old (M = 15.42; SD = .86). Students completed questionnaires to assess their levels of physical activity, self-identity, motivation, intention to be physically active and daily sitting time. The students' perceptions of their body height and mass were also tested. With the exception of walking MET values, the results showed gender differences in the variables tested. Male participants showed higher intrinsic motivation and lower amotivation than female participants. Furthermore, male students revealed higher levels of physical activity than female students. Finally, the research concluded with the importance of promoting intrinsic reasons for physical activity in order to encourage positive consequences in high school students.

    Abstract The aim of this study was to examine the relationships between gender and the educational grade on the one hand, and physical activity levels, motivation, self-identity, body dissatisfaction, the intention to be physically active and daily sitting time on the other, in a sample of Spanish high school adolescents. The sample consisted of 2087 Spanish students from the 3rd (n = 1141) and 4th grade (n = 946), both male (n = 1046) and female (n = 1041), ranging in age from 15 to 17 years old (M = 15.42; SD = .86). Students completed questionnaires to assess their levels of physical activity, self-identity, motivation, intention to be physically active and daily sitting time. The students’ perceptions of their body height and mass were also tested. With the exception of walking MET values, the results showed gender differences in the variables tested. Male participants showed higher intrinsic motivation and lower amotivation than female participants. Furthermore, male students revealed higher levels of physical activity than female students. Finally, the research concluded with the importance of promoting intrinsic reasons for physical activity in order to encourage positive consequences in high school students. PMID:29134046

    A recently validated trait personality framework is the HEXACO (honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience). Little is yet known about how the HEXACO personality dimensions and its subsets--particularly the dimension of honesty-humility--relates to physical activity and body size…

    Cyberbullying victimization and perpetration continues to be a serious public health, criminal justice, victimology, and educational problem in middle schools in the United States. Adolescents are at a higher risk of experiencing cyberbullying as a victim and/or as a bully given the frequency of their use of the Internet via social networking sites such as Facebook and mobile devices such as cell phones and tablets. To address this important problem, the purpose of this investigation was to examine cyberbullying victimization through communication technology as a predictor of cyberbullying perpetration, body image, healthy eating and dieting behaviors, and life satisfaction of sixth-, seventh-, and eighth-grade-level middle school students. The World Health Organization recruited participants by using a Health Behavior in School-Aged Children (HBSC) survey. In this in-class questionnaire, 6,944 middle school students were asked about their cyberbullying experiences as a victim and as a bully via Internet, email, and mobile communication technologies to obtain their evaluations of their body image, eating and dieting habits, and perceptions of life satisfaction. After controlling for demographic factors such as sex, age, and class level, this study found that cyberbullying victimization was a predictor of cyberbullying perpetration, body image dissatisfaction, dieting behaviors, and life satisfaction. However, this study did not find a correlation between cyberbullying victimization and students' healthy eating behaviors. This study also discussed each of the findings in the context of previous research findings. In addition, the study provides the strengths, limitations, and future directions for the future examination of cyberbullying victimization in middle schools.

    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.

    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. 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. 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. This study suggested there was no significant difference in eating disorder risk or exercise dependence between the three groups (NUTR, EXSC, and CON).

    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. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The aims of this study were to examine subjective health complaints among Norwegian adolescents and assess the development of gender differences in subjective health complaints between age 14 and 16; to investigate whether self-esteem, stress from schoolwork or body dissatisfaction affected adolescents' subjective health complaints; and determine whether these factors could explain the excess of subjective health complaints among girls. We used multiple linear regression analyses to analyse longitudinal survey data from 751 Norwegian adolescents at the ages of 14 and 16. The results from various cross-sectional and prospective analyses were compared. Girls reported more subjective health complaints than boys, and gender differences increased from age 14 to 16. Self-esteem and stress from schoolwork had cross-sectional and prospective associations with subjective health complaints. Stress from schoolwork at age 14 was also associated with changes in subjective health complaints from age 14 to 16. The cross-sectional mediation analyses indicated that self-esteem and stress from schoolwork accounted for 61% of the excess of subjective health complaints among girls at age 16. The same variables measured at age 14 accounted for 24% of the gender differences in subjective health complaints two years later. The investigated factors could not account for the increase in gender differences in subjective health complaints between ages 14 and 16. The findings showed that self-esteem and stress from schoolwork were associated with subjective health complaints during adolescence. These factors could partially explain the excess of subjective health complaints among girls.

    Self-perception of oral health status is a multidimensional construct that includes psychological, psychosocial and functional aspects of oral health. Contemporary concepts suggest that the evaluation of health needs should focus on clinical standards and socio-dental indicators that measure the impact of health/disease on the individual quality of life. Oral health cannot be dissociated from general health. This study evaluates a possible association between oral health status, body size, self-perception of oral health, self-perception of body size and dissatisfaction with body image in prepubertal children with mixed dentition, targeting the completion of children's health status assessment which will further allow the identification of individuals at risk and could be further used as an evaluation of the need for specific interventions. The present study is cross-sectional in design and uses data from 710 pre-pubertal children with mixed dentition. The outcome variables comprised one item self-perception of oral health: dmft/DMFT Index and Dental Aesthetic Index, body size, self-assessed body size and desired body size. Multiple logistic regression analyses were performed. The level of significance was set at 5%. More than a half (53.1%) of the participants with mixed dentition reported that their oral health was excellent or very good. In the unadjusted model, untreated decayed teeth, dmft score and body dissatisfaction levels had a significant contribution to poor self-perception of oral health, but after adjustment for gender, BMI status, dmft score, DMFT score and DAI score, only untreated decayed teeth OR = 1.293, 95%CI (1.120-1.492) and higher body dissatisfaction levels had a significant contribution. It was concluded that the need for dental treatment influenced self-perception of oral health in prepubertal children with mixed dentition, especially with relation to untreated decayed teeth. Since only body dissatisfaction levels, but not BMI, were

    Three cognitive constructs are risk factors for eating disorders: undue influence of weight and shape, concern about weight and shape, and body dissatisfaction (BD). Undue influence, a diagnostic criterion for eating disorders, is postulated to be closely associated with self-esteem whereas BD is postulated to be closely associated with body mass index (BMI). We understand less about the relationships with concern about weight and shape. The aim of the current investigation was examine the degree of overlap across these five phenotypes in terms of latent genetic and environmental risk factors in order to draw some conclusions about the similarities and differences across the three cognitive variables. A sample of female Australian twins (n=1056, including 348 complete pairs), mean age 35 years (S.D.=2.11, range 28-40), completed a semi-structured interview about eating pathology and self-report questionnaires. An independent pathways model was used to investigate the overlap of genetic and environmental risk factors for the five phenotypes. In terms of variance that was not shared with other phenotypes, self-esteem emerged as being separate, with 100% of its variance unshared with the other phenotypes, followed by undue influence (51%) and then concern (34%), BD (28%) and BMI (32%). In terms of shared genetic risk, undue influence and concern were more closely related than BD, whereas BMI and BD were found to share common sources of risk. With respect to environmental risk factors, concern, BMI and BD were more closely related to each other than to undue influence.

    The aim of the present study was to examine the causal relationships between psychological and social factors, being independent variables and body image dissatisfaction plus symptoms of eating disorders as dependent variables through the mediation of social comparison and thin-ideal internalization. To conduct the study, 477 high-school students from Tehran were recruited by method of cluster sampling. Next, they filled out Rosenberg Self-esteem Scale (RSES), Physical Appearance Comparison Scale (PACS), Self-Concept Clarity Scale (SCCS), Appearance Perfectionism Scale (APS), Eating Disorder Inventory (EDI), Multidimensional Body Self Relations Questionnaire (MBSRQ) and Sociocultural Attitudes towards Appearance Questionnaire (SATAQ-4). In the end, collected data were analyzed using structural equation modeling. Findings showed that the assumed model perfectly fitted the data after modification and as a result, all the path-coefficients of latent variables (except for the path between self-esteem and thin-ideal internalization) were statistically significant (p>0.05). Also, in this model, 75% of scores' distribution of body dissatisfaction was explained through psychological variables, socio-cultural variables, social comparison and internalization of the thin ideal. The results of the present study provid experimental basis for the confirmation of proposed causal model. The combination of psychological, social and cultural variables could efficiently predict body image dissatisfaction of young girls in Iran.

  3. What influences assessors' internalised standards?

    Purpose: The meaning assessors attach to assessment criteria during clinical placement is under-researched. While personal beliefs, values or expectations may influence judgements, there is scant evidence of how this manifests in a clinical attachment setting. This research explored the concept and source of internalised standards and how these may influence judgements. Methods: This study, within the constructivist paradigm, was informed by the principles of grounded theory. Seven radiation therapists, purposefully selected, were interviewed face-to-face using semi-structured interviews. The sample size allowed for the gathering of sufficient data for in-depth thematic analysis, using the functionality of CAQDAS (NVivo 9). Results: Radiation therapists' judgements when assessing students were influenced by their previous experience. They had different expectations of the appropriate standard for each criterion on students' assessment forms – relating to technical ability, clinical knowledge and attitude. They had their own set of values, or expectations which informed ‘internalised standards’ which influenced their judgements about student performance. Prior experience – as students and as qualified professionals – influenced these decisions. Conclusion: Assessment of students' performance may differ depending on the clinician conducting the assessment. Even where assessors are given the same criteria and training, this does not ensure reliability, as judgements are influenced by their internalised standards. This has implications for the design of more appropriate assessor training which recognises and addresses this phenomenon. These results will be of interest to radiation therapists, radiographers, medical educators, allied health professionals and any academic or professional body with responsibility for ensuring that we qualify competent practitioners. - Highlights: • Reliability of clinical assessment is of the upmost importance

    This study examined the associations among early family adversity (e.g., family violence, neglect), self-concept clarity (i.e., having a clear and coherent sense of one's own personal identity), thin-ideal internalization, and body dissatisfaction. Female university students in Australia (n=323) and adult female community members in the United States (n=371) completed self-report measures of the relevant constructs. In both samples, serial mediation analysis revealed that early family adversity was negatively associated with self-concept clarity, self-concept clarity was negatively associated with thin-ideal internalization, and thin-ideal internalization was positively associated with body dissatisfaction. These findings suggest that early adverse experiences might impair individuals' self-concept clarity, and that low self-concept clarity might increase the risk of internalization of the thin ideal (as a means of defining the self) and consequently body dissatisfaction. These findings also suggest possible avenues for prevention and intervention efforts. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Cognitive behavioural models of eating disorders highlight low self-esteem as a maintaining factor. This study explored the impact of positive and negative self-imagery on aspects of the working self (implicit and explicit self-esteem and self-concept clarity) in individuals with high body dissatisfaction (an important aspect of eating disorders). The impact of these images on state body satisfaction and affect was also explored. A group of participants with high body dissatisfaction completed measures of explicit self-esteem, self-concept clarity, state body satisfaction and affect prior to completing a negative (n = 33) or positive (n = 33) self-imagery retrieval task. Following this they completed the baseline measures and a measure of implicit self-esteem. Holding a negative self-image in mind had a negative effect on explicit self-esteem, whilst holding a positive self-image had a beneficial effect. There were no effects of imagery on implicit self-esteem. Holding a negative image in mind led to a significant reduction in self-concept clarity; however, positive self-imagery did not affect self-concept clarity. Holding a negative self-image in mind led to a decrease in body satisfaction and state affect. The opposite was found for the positive self-imagery group. Implicit self-esteem was not measured at baseline. Imagery techniques which promote positive self-images may help improve aspects of the working self, body satisfaction and affect in individuals with high levels of body dissatisfaction. As such, these imagery techniques warrant further investigation in a clinical population. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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. Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.

    Children with externalising problems are at risk of developing internalising problems as they grow older. The pathways underlying this developmental association remain to be elucidated. We tested two processes that could explain why some children with externalising problems develop internalising symptoms in preadolescence: a mediation model whereby the association between early externalising and later new internalising symptoms is explained by negative experiences; and a genetic model, whereby genes influence both problems. We used data from the Environmental Risk (E-Risk) Study, a 1994-1995 birth cohort of 2,232 twins born in England and Wales. We assessed externalising and internalising problems using combined mothers' and teachers' ratings at age 5 and 12. We measured bullying victimisation, maternal dissatisfaction and academic difficulties between age 7 and 10 and used linear regression analyses to test the effects of these negative experiences on the association between early externalising and later internalising problems. We employed a Cholesky decomposition to examine the genetic influences on the association. Children with externalising problems at age 5 showed increased rates of new internalising problems at age 12 (r = .24, p children with externalising problems develop internalising symptoms in preadolescence. Negative experiences also contribute to the association, possibly through gene-environment interplay. Mental health professionals should monitor the development of internalising symptoms in young children with externalising problems. © 2014 Association for Child and Adolescent Mental Health.

    Gay and bisexual men may be at heightened risk for using anabolic androgenic steroids (AAS). Few studies, however, have examined AAS use among gay and bisexual men living in countries outside the United States. In addition, few studies have explored the potential associations of AAS use with body image concerns beyond muscularity, including height and genitals, or with eating disorder symptoms and quality of life. Thus, we examined the associations of AAS use, and of thoughts about using AAS, with body image, eating disorder symptoms, and quality of life among gay and bisexual men living in Australia and New Zealand. A sample of 2733 gay and bisexual men completed an online survey promoted by paid nationwide advertisements to users of geosocial-networking smartphone applications. The prevalence of AAS use, and of thoughts about using AAS, were 5.2% (95% confidence interval [CI]: 4.4%, 6.1%) and 25.4% (95% CI: 23.8%, 27.1%), respectively. Multivariate analyses revealed that more frequent thoughts about using AAS were associated with being older, taller, and experiencing greater dissatisfaction with muscularity and height, less dissatisfaction with body fat, greater eating disorder symptoms, and lower subjective quality of life. Actual AAS users were more likely to be older, from a non-Australian/New Zealander cultural background, experiencing less dissatisfaction with body fat, and experiencing greater eating disorder symptoms. Psychopathology related to body image and eating disorders are associated with AAS use among gay and bisexual men living in Australia and New Zealand. Copyright © 2017 Elsevier B.V.

    Full Text Available OBJECTIVE: To examine the prevalence of body dissatisfaction and associated factors in 8- to 11-year-old schoolchildren. METHODS: A cross-sectional study including children aged 8- to 11-years enrolled in public and private schools in Porto Alegre, Southern Brazil, was carried out from August to December, 2001. A total of 901 subjects were selected through cluster sampling. Participants answered a questionnaire aimed at measuring body dissatisfaction and self-esteem and questions about family and social pressures on weight change. Height and weight were measured. The relationship between body dissatisfaction and the variables studied was measured by logistic regression. RESULTS: The prevalence of body dissatisfaction was 82%. Fifty-five percent of the girls wanted a thinner body size, and 28% desired a larger one; the estimates for the boys were 43% and 38%, respectively. Children with the lowest self-esteem (OR=1.80; 95% CI: 1.13-2.89 and who thought their parents (OR=6.10; 95% CI: 2.95-12.60 and friends (OR=1.81; 95% CI: 1.02-3.20 expected them to be thinner showed a higher chance of presenting body dissatisfaction. CONCLUSIONS: Body dissatisfaction was highly prevalent among the evaluated schoolchildren, especially in those with lower self-esteem and who thought their parents and friends expected them to be thinner.OBJETIVO: Examinar a prevalência de insatisfação corporal e fatores associados em escolares entre oito e 11 anos.

    This study aimed to investigate the relationship among three potential protective factors: satisfaction with life, three routes to well-being and meaning in life, and eating disorder symptoms and body dissatisfaction in male and female adolescents. The sample was composed of 247 adolescent students aged 13 to 18 years. The findings of this study support the protective roles of satisfaction with life and engagement as routes to well-being in male adolescents and particularly in female adolescents. Positive interventions to promote satisfaction with life and engagement in activities in school are highly recommended.

    2012-03-01

    This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.

    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.

    Full Text Available A insatisfação com a imagem corporal é avaliada por meio da diferença entre a figura real e a idealizada e pode influenciar comportamentos alimentares. OBJETIVO: Avaliar a insatisfação corporal de universitárias do sexo feminino nas cinco regiões do país e possíveis associações e correlações com a idade, o estado nutricional, a renda e o grau de escolaridade do chefe da família. MÉTODOS: 2.402 universitárias responderam à Escala de Silhuetas de Stunkard. As regiões foram comparadas por meio da análise de variância; correlações entre as variáveis foram analisadas pelos coeficientes de Pearson e Spearman. RESULTADOS: 64,4% gostariam de ser menores do que sua figura atual, e mesmo as estudantes eutróficas escolheram figuras saudável e ideal menores. Na região Norte foram apontados os mais magros padrões ideais e de saúde e na região Centro-Oeste, os maiores. CONCLUSÃO: A ocorrência de insatisfação corporal foi bastante expressiva, com algumas diferenças regionais e sociodemográficas que devem ser consideradas.Body image dissatisfaction is evaluated according to the difference between the real figure and idealized figure, and could influence eating behaviors. OBJECTIVE: To evaluate body dissatisfaction among female university students from the five regions of Brazil and possible associations and correlations with age, nutritional status, individual income and parental education. METHODS: 2,402 students answered the Stunkard's Body Image Scale and regions were compared by variance analysis, and correlations among variables with Pearson's and Spearman's coefficients. RESULTS: 64.4% desired a figure smaller than their actual one, and even the normal weight range students chose ideal and healthy smaller figures. In North region the ideal and healthy patterns were smaller and in the Central West bigger.

    Full Text Available The purpose of this investigation was to evaluate body image dissatisfaction in relation to low self-esteem due to physical appearance in students of the Faculty of Medicine at the University of Los Andes in Mérida, Venezuela.  It was a non-experimental and correlational study.  The sample included 189 students (27% male and 73% female with an average age of 19.58 ± 1.57 (men: 19.81 years of age ± 1.74 and women: 20.24 years of age ± 1.76.  Participants were intentionally selected from first-year courses of the Medicine, Nursing and Nutrition programs.  The Body Shape Questionnaire (BSQ (Cooper and Taylor, 1987 was the instrument used to measure body image dissatisfaction and Graffar’s modified method (Méndez and De Méndez, 1994 was applied to determine the participants’ socioeconomic status.  A descriptive analysis (frequency, percentages, mean and an inferential analysis (one-way ANOVA were applied to the data using SPSS (Statistical Package for Social Sciences version 9.0.  One of the most important findings in this study was the determination of a statistically significant relationship between dissatisfaction and body image and between low self-esteem and gender χ2 (2, N= 189 = 9.686, p=0.008.  Using ANOVA also helped determine that differences in the mean for dissatisfaction and low self-esteem levels with body image and gender are statistically significant, F= 11.236; p=0.008, F=10.23; p=0.002, respectively.  Conclusions: results obtained suggest a relationship between dissatisfaction and low self-esteem due to physical appearance. Consequently, subjects reject their body image because of a distorted or undistorted perception of their physical appearance, which can possibly affect self-esteem.  Moreover, it is observed that the students’ psychological health is more related to their satisfaction with their body-image than to the way their body image is perceived.

    Previous studies have already found a positive association between attachment and disordered eating attitudes and behaviors in children and adolescents. However, to our knowledge, no experimental studies have examined whether changes in negative and/or positive affect moderate the association between attachment anxiety and body dissatisfaction in children. A controlled laboratory setting was used to investigate whether changes in state negative and/or positive affect moderate the association between attachment anxiety and body satisfaction in a sample of 81 children (M age =11.74). The changes in state affect were caused by the exposure to a performance-related stressor using the Trier Social Stress Test for Children. Children with high levels of attachment anxiety reported a decrease in body satisfaction, but only if the TSST-C led to a decrease in their positive affect. Early detection and intervention programs may benefit from addressing insecure attachment and maladaptive emotion regulation in children. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This study was done to examine not only the relationships between body mass index (BMI), self-esteem, body image dissatisfaction (BID) and mental health, according to gender, but the mediating role of BID on mental health in relation to BMI and self-esteem among early adolescents. Data from 576 (296 boys and 280 girls) elementary school students in grades 5 to 6 were collected. A multiple-group path analysis was utilized to examine the relationships between BMI, self-esteem, BID and mental health by gender. In the path analysis for all students, poor mental health was related directly to BID, while it was indirectly related to BMI and self-esteem. In the multiple-group path analysis of both genders, BID was found to have a significant direct and indirect effect on mental health for girls alone. The findings suggested that BID should be examined early to prevent poor mental health in early adolescent girls. This study helps to elucidate the role of early adolescent BID on mental health and provides insight for further prevention and intervention programs in school and community mental health settings.

    Studies on the mechanisms of neuronal amyloid-β (Aβ) internalisation are crucial for understanding the neuropathological progression of Alzheimer's disease (AD). We here investigated how extracellular Aβ peptides are internalised and focused on three different pathways: (i) via endocytic mechanisms, (ii) via the receptor for advanced glycation end products (RAGE) and (iii) via the pore-forming protein perforin. Both Aβ 40 and Aβ 42 were internalised in retinoic acid differentiated neuroblastoma (RA-SH-SY5Y) cells. A higher concentration was required for Aβ 40 (250 nM) compared with Aβ 42 (100 nM). The internalised Aβ 40 showed a dot-like pattern of distribution whereas Aβ 42 accumulated in larger and distinct formations. By confocal microscopy, we showed that Aβ 40 and Aβ 42 co-localised with mitochondria, endoplasmic reticulum (ER) and lysosomes. Aβ treatment of human primary cortical neurons (hPCN) confirmed our findings in RA-SH-SY5Y cells, but hPCN were less sensitive to Aβ; therefore, a 20 (Aβ 40 ) and 50 (Aβ 42 ) times higher concentration was needed for inducing uptake. The blocking of endocytosis completely inhibited the internalisation of Aβ peptides in RA-SH-SY5Y cells and hPCN, indicating that this is a major pathway by which Aβ enters the cells. In addition, the internalisation of Aβ 42 , but not Aβ 40 , was reduced by 55 % by blocking RAGE. Finally, for the first time we showed that pore formation in cell membranes by perforin led to Aβ internalisation in hPCN. Understanding how Aβ is internalised sheds light on the pathological role of Aβ and provides further ideas of inhibitory strategies for preventing Aβ internalisation and the spreading of neurodegeneration in AD.

    This study aims to describe psychological problems, self-esteem difficulties and body dissatisfaction in a sample of adolescents with acquired brain lesions and to compare them with an age- and gender-matched control group. In an experimental design, the psychological profile of 26 adolescents with brain lesions of traumatic or vascular aetiology, aged 12-18 years, was compared with that of 18 typically-developing subjects. Moreover, within the clinical group, patients with TBI were compared with patients with vascular lesions. The psychological and adaptive profile of the adolescents was assessed by a specific protocol, including CBCL, VABS, RSES, EDI-2 and BES. Adolescents with brain lesions showed more marked psychological problems than their healthy peers; they also presented with a greater impairment of adaptive skills and a lower self-esteem. No significant differences were found between patients with traumatic lesions and patients with vascular lesions. Adolescents with acquired brain lesions were at higher risk to develop psychological and behavioural difficulties. Furthermore, in the clinical sample, some variables such as the long hospitalization and isolation from family and peers were associated to a greater psychological burden than the aetiology of the brain damage.

    Full Text Available Abstract 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.

    We report polymer capsule-based probes for quantifying the pressure exerted by cells during capsule internalisation (P in ). Poly(methacrylic acid) (PMA) capsules with tuneable mechanical properties were fabricated through layer-by-layer assembly. The P in was quantified by correlating the cell-induced deformation with the ex situ osmotically induced deformation of the polymer capsules. Ultimately, we found that human monocyte-derived macrophage THP-1 cells exerted up to approximately 360 kPa on the capsules during internalisation.

    This article introduces the importance of equivalence framing for understanding how satisfaction measures affect citizens’ evaluation of public services. Does a 90 percent satisfaction rate have a different effect than a logically equivalent 10 percent dissatisfaction rate? Two experiments were...... conducted on citizens’ evaluations of hospital services in a large, nationally representative sample of Danish citizens. Both experiments found that exposing citizens to a patient dissatisfaction measure led to more negative views of public service than exposing them to a logically equivalent satisfaction...... metric. There is some support for part of the shift in evaluations being caused by a negativity bias: dissatisfaction has a larger negative impact than satisfaction has a positive impact. Both professional experience at a hospital and prior exposure to satisfaction rates reduced the negative response...

    Fresh produce such as lettuce (Lactuca sativa) has often been linked to epidemic viral gastroenteritis. In these cases, it is unknown whether the viral contamination has occurred during the growing or the processing of the implicated product. In this study lettuce was grown in the presence of enteric viruses, and the uptake of viruses via the roots into the edible parts (leaves and stem) of the lettuce plants was investigated, for plants with both intact and damaged roots. The roots of lettuce, growing either in hydroponic culture or in soil, were exposed to canine calicivirus (CaCV) and a human genogroup 2 norovirus (HuNoV) by these being added into the water or soil in which the lettuce was growing. Leaves from lettuce plants and seedlings were examined for viruses by real-time RT-PCR. When the lettuce plants were exposed to very high concentrations of CaCV, the virus was detected in lettuce leaves, indicating contamination via the roots, but the frequency of positive results was low. Internalisation occurred in both seedlings and grown plants, in both hydroponic and soil cultures, and occurred whether the roots were intact or damaged. However, internalisation of HuNoV was not detected in any of the experimental set ups, although the concentrations to which the plants were exposed were relatively high. Based on these results, viral contamination of lettuce plants via roots cannot be excluded, but is apparently not an important transmission route for viruses.

    As concern grows about the environmental aspect of energy use, it is increasingly suggested in recent years that energy pricing should take negative externalities of energy use into account. A large body of literature, both theoretical and applied, has grown up over the years proposing a variety of options and methods for internalising environmental costs. However, most of these theories and methods, developed in the industrialised countries, have hitherto neglected two aspects of developing economies: the existence of informal sector in the economy and widespread use of traditional energies. This paper discusses the issues related to internalising environmental costs through price mechanism when these two aspects are included. It also calls for a more careful analysis of energy and environmental policies. (author)

    It is known that behavioral disorders and altered food intake are linked to ballet dancers. Thus, the aim of the present study was to investigate the body composition, dietetic profile, self-perceived body image and social desirability in professional ballet dancers. This study was conducted from April to October 2010 in athletes screened for nutritional evaluation. Anthropometric, dietary, social desirability and self-perceived body image evaluation were performed to attend the aim of study. We found that ballet dancers are highly trained and eutrophic, although female dancers had higher adiposity and fat intake than male dancers. In addition, it was observed low consumption of calcium, dietary fiber, potassium, magnesium and vitamin A. Moreover, 30% of male ballet dancers have a strong desire for social acceptance. When the body image was evaluated by Body Shape Questionnaire (BSQ), was reported that 40% of the ballet female dancers have of moderate to severe alteration in body image and 20% of male dancers had slight alteration. Furthermore, the Drawings and Silhouettes Scale showed that 80% of male dancers wish to have a smaller or larger silhouette than the current self-perceived and 60% of the female dancers would like to have a silhouette lower than the self-perceive as current. Collectively, our results shown that most of the dancers were eutrophic, but female athletes have higher adiposity and present strong desire for a different shape of current. Furthermore, was found increased fat intake in female group; however, deficiencies in consumption of dietary fiber, calcium, potassium, magnesium and vitamin A were found in both gender.

    Full Text Available This study investigates the prevalence of weight misperception, weight preference, and body shape dissatisfaction (BSD among young-adult Nigerians and assesses the impact of these factors on population quality-of-life (QOL. Relevant anthropometric data were collected according to internationally accepted protocols. Weight perception, weight preference, and BSD were measured using Stunkard silhouettes, while QOL was determined by subjective self-reporting. The results show that 26.7% of the population (18.8% for males and 34.5% for females misperceived their weight. Among overweight participants, 56.6% (males and 38.3% (females thought they were thinner, while 11.5% (males and 43.3% (females thought they were heavier. Thin and obese males misperceived their weights more than their female counterparts. BSD was found in 62% of the population (52% for males and 71% for females and was highest among obese participants (91.9% and lowest among normal-weight participants (58.2%, irrespective of sex. In participants with BSD, QOL was worse in thin and normal-weight respondents who preferred to be heavier and in overweight respondents who preferred to be thinner. The high prevalence of weight misperception may lead to inappropriate weight loss habits, while BSD, a normative discontent in this population, negatively impacts subject QOL.

    2007-05-01

    Full Text Available The aim of the article is to focus on hegemony as it relates to the issue of sexuality and the trauma imposed on sexual minorities. A point of departure is that social identity theories can shed light on homophobia. The article argues that an empathic approach to those traumatised by internalised homophobia calls for a gay-friendly psychotherapy/analysis. The article reflects particularly on how heteronormativity maintains homophobia. It also illustrates the relationship between homophobia and social scientific insights regarding personality types and gender. The concepts homophobia and the internalisation of homophobia are discussed by focusing on aspects such as personality types and violence. The article finds that blind submission to heteronormativity, an outdated social construct, traumatises those who do not conform to the hetero norm, in two ways: hegemony is one consequence, and internalised homophobia is another.

    Background: Body hair removal is a behaviour that has become normative among women in Westernised cultures, and is presented by the media as the feminine ideal, despite being painful and a potential cause of infection. Of concern, removal may be part of a more global pattern of appearance dissatisfaction and risky sexual behaviour. The aim of the present study was to examine the relationships among pubic hair removal, body image and sexual health indicators. Methods: Women (n=264; Mage=33.82, s.d.=11.13, range=18-66) completed self-report questionnaires assessing these constructs, including an assessment of body hair removal practices. Results: Greater appearance concerns (as measured by thin-ideal internalisation, appearance investment and self-objectification) and sexual health indicators (i.e. less condom use self-efficacy when a partner disapproves of condom use) all predicted greater importance of reasons for pubic hair removal (R2=0.315, F(8184)=9.97, Pwomen who removed a greater amount of hair reported more thin-ideal internalisation and appearance investment than those who removed less hair. Conclusions: Women who express stronger reasoning for pubic hair removal, and remove a larger amount of it, may endorse problematic beliefs and behaviours particularly related to appearance concerns. It is important for practitioners to consider this practice as distinct from grooming and to be aware of its association with a broader array of risky beliefs and behaviours that can compromise women's well-being.

    Cells are protected from the surrounding environment by plasma membrane which is impenetrable for most hydrophilic molecules. In the last 10 years cell-penetrating peptides (CPPs) have been discovered and developed. CPPs enter mammalian cells and carry cargo molecules over the plasma membrane with a molecular weight several times their own. Known transformation methods for plant cells have relatively low efficiency and require improvement. The possibility to use CPPs as potential delivery vectors for internalisation in plant cells has been studied in the present work. We analyse and compare the uptake of the fluorescein-labeled CPPs, transportan, TP10, penetratin and pVEC in Bowes human melanoma cells and Nicotiana tabacum cultivar (cv.) SR-1 protoplasts (plant cells without cell wall). We study the internalisation efficiency of CPPs with fluorescence microscopy, spectrofluorometry and fluorescence-activated cell sorter (FACS). All methods indicate, for the first time, that these CPPs can internalise into N. tabacum cv. SR-1 protoplasts. Transportan has the highest uptake efficacy among the studied peptides, both in mammalian cells and plant protoplast. The internalisation of CPPs by plant protoplasts may open up a new effective method for transfection in plants.

    Full Text Available Abstract Background Peptide aptamers are combinatorial protein reagents that bind to targets with a high specificity and a strong affinity thus providing a molecular tool kit for modulating the function of their targets in vivo. Results Here we report the isolation of a peptide aptamer named swiggle that interacts with the very short (21 amino acid long intracellular domain of membrane type 1-metalloproteinase (MT1-MMP, a key cell surface protease involved in numerous and crucial physiological and pathological cellular events. Expression of swiggle in mammalian cells was found to increase the cell surface expression of MT1-MMP by impairing its internalisation. Swiggle interacts with the LLY573 internalisation motif of MT1-MMP intracellular domain, thus disrupting the interaction with the μ2 subunit of the AP-2 internalisation complex required for endocytosis of the protease. Interestingly, swiggle-mediated inhibition of MT1-MMP clathrin-mediated internalisation was also found to promote MT1-MMP-mediated cell migration. Conclusions Taken together, our results provide further evidence that peptide aptamers can be used to dissect molecular events mediated by individual protein domains, in contrast to the pleiotropic effects of RNA interference techniques.

    Depression is a common psychological problem and females have been found to be at greater risk for this disorder than males. Although numerous studies have found that physical exercise is negatively associated with risk of depression, some studies suggest that negative exercise attitudes may increase the risk of depression. The present study used the survey method to examine the relationship between depressive symptoms, exercise performance dissatisfaction, body dissatisfaction, and physical exercise among a sample of 895 undergraduate university students. Females reported higher depression and exercise performance dissatisfaction scores than males; however, there were no gender differences in body dissatisfaction. Exercise performance dissatisfaction was positively associated with depression among both males and females. Physical exercise was negatively associated with depression among males, but not among females. The possibility of screening participants enrolled in exercise programs for performance dissatisfaction is discussed as negative exercise attitudes may diminish the positive impact of exercise on depressed mood.

    The caveolar cycle is thought to be regulated by synchronised function of kinases and phosphatases. Using ocadaic acid--a serine/threonine protein phosphatase inhibitor--and an inhibitor of tyrosine phosphatase (sodium orthovanadate) we have followed the internalisation of caveolae. Since albumin binding to its receptor (gp60) can induce pinching off of caveolae from the plasma membrane, we also used this physiological ligand to induce the internalisation. Our confocal microscopic results show that both ocadaic acid and vanadate treatments have significantly decreased caveolin (caveolin-1 and -2) labelling on the cell surface, while the cytoplasmic labelling became much stronger. Quite often large, strongly labelled "granules" appear at the perinuclear region. Very strong caveolin labelling was detected along the actin-cytoskeleton suggesting that caveolae might move along these filaments. Our electron microscopic results also show an intensive caveolae pinching off from the plasma membrane. After ocadaic acid and vanadate treatments the number of surface connected vesicles (caveolae) decreases. At the same time, large multivesicular bodies (termed caveosomes) appear in the perinuclear area of the cytoplasm. By immunoprecipitation and Western blot analysis we detect an increased tyrosine phosphorylation of a approximately 29kDa protein in ocadaic acid and vanadate treated samples. This protein was identified as caveolin-2. No significant change in the tyrosine phosphorylation of caveolin-1 was found. From these data we can conclude that caveolae internalisation is regulated by phosphorylation of caveolin-2.

  19. Conformity and Internalisation in a Participative Decision Making Process

    International Nuclear Information System (INIS)

    Bombaerts, Gunter

    2003-01-01

    This paper reflects upon the stretching concept of the RISCOM model. We agree with the Habermassian point of departure that a competent speaker makes validity claims on truth, legitimacy and authenticity and partially with the Dialogue Project's conclusions that opening the black box of science is not possible in a decision making process (DMP) on a highly technical issue. Accordingly, we see an important role for a regulator to stretch the implementer, i.e. balance commercial and guardian ethics in the DMP. However, some caution is needed. Conformity studies indicate the large influence of group norms on individuals. When individuals lack personal reference frames of a particular issue they are prone to conform. The more values are shared, the more group members are convinced of the correctness. And social psychology shows more. In studies on persuasion, a difference between compliance and internalisation is made. Compliance is attained from rewards and coercive sources of power, whereas internalisation originates from expertise, legitimacy and credibility. Because of the shift to legitimacy and authenticity in the DMP, alignment of the norms and internalisation of discussed values becomes more apparent in the RISCOM participation model. Conformity reactions and possible internalisation are normal aspect of human interaction and not necessarily a negative aspect of public involvement. But keeping the importance of conformity in mind, a few consequences can be mentioned with regard to the relation implementer-regulator, the non-participation majority, and non-participating critics. The new role of the regulator and the involved public in the RISCOM mode] cannot absolutely avoid the risks due to conformity, it can only decrease the conformity influence

    Full Text Available Induced internalisation of functional proteins into cultured cells has become an important aspect in a rising number of in vitro and in vivo assays. The endo-lysosomal entrapment of the transduced proteins remains the major problem in all transduction protocols. In this study we compared the efficiency, cytotoxicity and protein targeting of different commercially available transduction reagents by transducing a well-studied fluorescently labelled protein (Atto488-bovine serum albumin into cultured human sarcoma cells. The amount of internalised protein and toxicity differed between the different reagents, but the percentage of transduced cells was consistently high. Furthermore, in all protocols the signals of the transduced Atto488-BSA were predominantly punctual consistent with an endosomal localisation. To overcome the endosomal entrapment, the transduction protocols were combined with a photochemical internalisation (PCI treatment. Using this combination revealed that an endosomal disruption is highly effective in cell penetrating peptide (CPP mediated transduction, whereas lipid-mediated transductions lead to a lower signal spreading throughout the cytosol. No change in the signal distribution could be achieved in treatments using non-lipid polymers as a transduction reagent. Therefore, the combination of protein transduction protocols based on CPPs with the endosomolytic treatment PCI can facilitate protein transduction experiments in vitro.

    Helicobacter pylori has high global infection rates and can cause other undesirable clinical manifestations such as duodenal ulcer (DU) and gastric cancer (GC). Frequencies of re-infection after therapeutic clearance and rates of DU versus GC vary geographically and differ markedly between developed and developing countries, which suggests additional factors may be involved. The possibility that, in vivo, lactoferrin (Lf) may play a subtle role in modulating micronutrient availability or bacterial internalisation with implications for disease etiology is considered. Lf is an iron binding protein produced in mammals that has antimicrobial and immunomodulatory properties. Some bacteria that regularly colonise mammalian hosts have adapted to living in high Lf environments and we investigated if this included the gastric pathogen H. pylori. We found that H. pylori was able to use iron from fully iron-saturated human Lf (hLf) whereas partially iron-saturated hLf (apo) did not increase H. pylori growth. Instead, apo-hLf increased adherence to and internalisation of bacteria into cultured epithelial cells. By increasing internalisation, we speculate that apo-human lactoferrin may contribute to H. pylori's ability to persistence in the human stomach, an observation that potentially has implications for the risk of H. pylori-associated disease.

    The study investigated factors associated with internalising emotional and behavioural problems among adolescents displaced during the most recent Chechen conflict. A cross-sectional survey (N=183) examined relationships between social support and connectedness with family, peers and community in relation to internalising problems. Levels of internalising were higher in displaced Chechen youth compared to published norms among non-referred youth in the United States and among Russian children not affected by conflict. Girls demonstrated higher problem scores compared to boys. Significant inverse correlations were observed between family, peer and community connectedness and internalising problems. In multivariate analyses, family connectedness was indicated as a significant predictor of internalising problems, independent of age, gender, housing status and other forms of support evaluated. Sub-analyses by gender indicated stronger protective relationships between family connectedness and internalising problems in boys. Results indicate that family connectedness is an important protective factor requiring further exploration by gender in war-affected adolescents. PMID:22443099

    2010-06-01

    Full Text Available Abstract 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.

    Research examining the impact on adolescent boys of exposure to muscular, athletic, idealised male images has been limited. This research had two aims (i) to investigate the mean effect on state body satisfaction and mood of exposure to idealised male images in adolescent boys, and, (ii) to identify individual attributes that predicted change in state body satisfaction, depression and anxiety following image exposure. One hundred and six boys (mean age=15.6 years) completed a self-report questionnaire on body image attitudes and psychological status. One week later, participants were divided into two groups, one that viewed idealised male images (experimental condition) while the other viewed non-figure advertising images (control condition). Three body satisfaction Visual Analogue Scale (VAS), and a depression and anxiety VAS were completed immediately prior to and following image exposure. In the experimental compared to control condition, there were no significant changes on Want Toned Body, Want to Change Body Shape, Depression and Anxiety VAS following image exposure. However, there was a significant improvement in Like Body Shape VAS. In the experimental group, high internalisation of the muscular, athletic ideal predicted more negative response to viewing images on the body image and Depression VAS. Prior body dissatisfaction significantly predicted negative response to Body Shape Liking and Anxiety VAS. While on average, adolescent boys in this research were not negatively affected by exposure to idealised male images, reaction to exposure is dependent on individual attributes.

    The nursing shortage is a critical issue in many countries. High turnover rates among nurses is contributing to the shortage, and job dissatisfaction, intention to leave, and burnout have been identified as some of the predictors of nurse turnover. A well-established body of evidence demonstrates that the work environment for nurses influences nurse job dissatisfaction, intention to leave, and burnout, but there never has been a study undertaken in Thailand to investigate this relationship. To investigate how work environment affects job dissatisfaction, burnout, and intention to leave among nurses in Thailand. The study used a cross-sectional survey to collect data from 1351 nurses working in 43 inpatient units in five university hospitals across Thailand. The participants completed the Practice Environment Scale of the Nursing Work Index, the Maslach Burnout Inventory, and measures of job dissatisfaction and intention to leave. Logistical regression models assessed the association between work environment and nurse-reported job dissatisfaction, burnout, and intent to leave. Nurses working in university hospitals with better work environments had significantly less job dissatisfaction, intention to leave, and burnout. The nurse work environment is a significant feature contributing to nurse retention in Thai university hospitals. Improving the work environment for nurses may lead to lower levels of job dissatisfaction, intention to leave, and burnout. Focusing on these nurse outcomes can be used as a strategy to retain nurses in the healthcare system. Addressing the challenges of poor work environments requires coordinated action from policymakers and health managers. © 2016 International Council of Nurses.

    Research purpose: This article presents an effort to describe a value internalisation effort within a South African public service organisation as well as the results of a subsequent evaluation to ascertain to what extent those efforts actually led to internalisation throughout the organisation. A set of actions and practices were implemented within the public service organisation; the intent was that they should enhance value internalisation in the organisation. A long-term strategy of value internalisation was followed that focussed mainly on the clear articulation and communication of the values through different communication mediums and platforms, such as road shows and branded value material hand-outs, as well as through extensive value internalisation training. Motivation for the study: Documentation of value internalisation processes and its evaluation, especially in South African public service organisations is extremely rare. To ensure that public service organisations do not repeat the same mistakes in their value internalisation practices and implementation processes, proper documentation of these processes in the public and research domains are needed. The need for the evaluation of value internalisation programmes should also be propagated as in many instances, programmes are implemented, but the subsequent success thereof is never evaluated. Research design, approach and method: A survey questionnaire consisting of a 5-point rating scale was developed to measure the extent of value internalisation after the implementation of long-term internalisation strategies. Employees at different levels and in different units of the organisation participated in the survey. Main findings: Results (N = 941 reflected lower than expected mean scores for each value component. In addition, differences in internalisation extent were found between two demographic variables, namely population groupings and organisational units. Practical/managerial implications: The

    Tight regulation of signalling activity is crucial for proper tissue patterning and growth. Here we investigate the function of Pentagone (Pent), a secreted protein that acts in a regulatory feedback during establishment and maintenance of BMP/Dpp morphogen signalling during Drosophila wing development. We show that Pent internalises the Dpp co-receptors, the glypicans Dally and Dally-like protein (Dlp), and propose that this internalisation is important in the establishment of a long range Dpp gradient. Pent-induced endocytosis and degradation of glypicans requires dynamin- and Rab5, but not clathrin or active BMP signalling. Thus, Pent modifies the ability of cells to trap and transduce BMP by fine-tuning the levels of the BMP reception system at the plasma membrane. In addition, and in accordance with the role of glypicans in multiple signalling pathways, we establish a requirement of Pent for Wg signalling. Our data propose a novel mechanism by which morphogen signalling is regulated. DOI: http://dx.doi.org/10.7554/eLife.13301.001 PMID:27269283

    Bordetella pertussis causes whooping cough, a respiratory infectious disease that is the fifth largest cause of vaccine-preventable death in infants. Though historically considered an extracellular pathogen, this bacterium has been detected both in vitro and in vivo inside phagocytic and non-phagocytic cells. However the precise mechanism used by B. pertussis for cell entry, or the putative bacterial factors involved, are not fully elucidated. Here we find that adenylate cyclase toxin (ACT), one of the important toxins of B. pertussis, is sufficient to promote bacterial internalisation into non-phagocytic cells. After characterization of the entry route we show that uptake of "toxin-coated bacteria" proceeds via a clathrin-independent, caveolae-dependent entry pathway, allowing the internalised bacteria to survive within the cells. Intracellular bacteria were found inside non-acidic endosomes with high sphingomyelin and cholesterol content, or "free" in the cytosol of the invaded cells, suggesting that the ACT-induced bacterial uptake may not proceed through formation of late endolysosomes. Activation of Tyr kinases and toxin-induced Ca(2+)-influx are essential for the entry process. We hypothesize that B. pertussis might use ACT to activate the endocytic machinery of non-phagocytic cells and gain entry into these cells, in this way evading the host immune system.

    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

    Full Text Available INTRODUCTION: Obesity is related to numerous negative consequences for physical and mental health. It is often associated with the presence of binge eating disorder, body image dissatisfaction, and general psychopathology. OBJECTIVE: To assess the effects of an interdisciplinary lifestyle therapy on binge eating symptoms, depression, anxiety, body dissatisfaction, and quality of life in obese adults. METHODS: A total of 49 obese adults (body mass index = 37.35±5.82 kg/m²; age = 44.14±10.00 years participated in a weight-loss program for 6 months. Symptoms suggestive of binge eating, body dissatisfaction, depression, anxiety, and quality of life were measured using self-reported questionnaires. Food intake was assessed using a 3-day dietary record. Data were analyzed using analysis of variance (ANOVA. RESULTS: ANOVA results showed a reduction in binge eating symptoms and in body dissatisfaction results. Depression and anxiety symptoms also decreased, and an increase was observed in quality of life scores. After therapy, a significant improvement was observed in dietary patterns, as well as significant weight loss. A positive correlation was found between variation of anxiety symptoms and lipid intake. Binge eating symptoms were associated with anxiety symptoms and body image dissatisfaction, and body image dissatisfaction correlated positively with anxiety symptoms in males only. In females, a positive correlation was observed between depression and binge eating symptoms. CONCLUSION: The interdisciplinary therapy was effective in promoting positive physical and psychological changes and in improving the quality of life of obese adults.INTRODUÇÃO: A obesidade se relaciona com inúmeras consequências negativas para a saúde física e mental.

    Following evidence that certain protein hormones can enter target cells the present investigation was undertaken which shows that gonadotrophin-induced receptor loss may occur by a process of internalisation of the hormone-receptor complex following the initial interaction of gonadotrophin with the cell surface. Localisation studies were carried out in 33-d old female rats previously treated with pregnant mare serum gonadotrophin and human chorionic gonadotrophin (hCG) to induce ovarian luteinisation. Animals were injected with 125 I-hCG to label the ovarian receptors for luteinising hormone in vivo. Microscope autoradiographs demonstrating distribution of 125 I-hCG in ovaries at various times following injection are shown. The combined results from the autoradiographs and from solubilisation experiments were used to determine the location and nature of the hCG-receptor complex following occupancy and loss of receptors from the plasma membrane of luteinised ovarian cells.

  19. Internalising discourses of parenting blame: Voices from the Field

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available This paper investigates the intertwining of a discourse of parental blame with the legacy of institutionalised neglect and the current roll-back of state support and services in two of Ireland's most socially marginalised and economically disadvantaged communities. In the course of fieldwork conducted to explore narratives of community safety, the authors were struck by the continual, unprompted emergence of a divisive and enduring belief that community problems could be primarily traced to 'bad parents' and 'bad parenting'. This article argues/identifies that the internalisation of a powerfully evocative discourse of blame works to absolve the state of all responsibility for the conditions in which marginalised communities are forced to live; it legitimises current and future cutbacks by portraying such communities as irresponsible and as the creators of their own problems; it distorts and distracts discussion away from necessary and critical questioning of state accountability by promoting a reductive, individualised understanding of what are complex, collective responsibilities. The internalisation of discourses of culpability operates to the benefit of the state, where 'bad' parents are understood to be 'undeserving' citizens. Finally, we argue that the ability of the state to cut back social funding and to roll back on previous commitments depends, in a large part, on the willingness of the wider community to believe that responsibility for long term social and economic marginalisation and associated problems rests, not with the state, but with 'bad' and 'undeserving' citizens (Adair 2005; Edelman 1998; Lens 2002; Welsh and Parsons 2006. Promoting that willingness is achieved through continual media and public sphere portrayals of the poor, and particularly of working class parents, as dangerously and overly fertile (Tyler 2008; Wilson and Huntington 2005, as non-contributors to prosperity and as over contributors to decline (Skeggs 2005

    Growth of normal cells is anchorage-dependent because signalling through multiple pathways including Erk, PI 3-kinase and Rac requires integrin-mediated cell adhesion 1. Components of these pathways localize to low density, cholesterol-rich domains in the plasma membrane named “lipid rafts” 2,3 or “cholesterol enriched membrane microdomains” (CEMM) 4. We previously reported that integrin-mediated adhesion regulates CEMM trafficking such that cell detachment from the extracellular matrix (ECM) triggers CEMM internalisation and clearance from the plasma membrane 5. We now report that this internalisation is mediated by dynamin-2 and caveolin-1. Internalisation requires phosphorylation of caveolin-1 on tyrosine 14. A shift in localisation of phospho-caveolin-1 from focal adhesions to caveolae induces CEMM internalisation upon cell detachment, which mediates inhibition of Erk, PI 3-kinase and Rac. These data define a novel molecular mechanism for growth and tumour suppression by caveolin-1. PMID:16113676

    Internalisation of the mu opioid receptor from the surface of cells is generally achieved by receptor occupancy with agonist ligands of high efficacy. However, in many situations the potent analgesic morphine fails to promote internalisation effectively and whether there is a direct link between this and the propensity for the sustained use of morphine to result in both tolerance and dependence has been studied intensely. Although frequently described as a partial agonist, this characteristic appears insufficient to explain the poor capacity of morphine to promote internalisation of the mu opioid receptor. Experiments performed using both transfected cell systems and ex vivo/in vivo models have provided evidence that when morphine can promote internalisation of the mu receptor there is a decrease in the development of tolerance and dependence. Although aspects of this model are controversial, such observations suggest a number of approaches to further enhance the use of morphine as an analgesic.

  6. Rab5 regulates internalisation of P2X4 receptors and potentiation by ivermectin.

    Science.gov (United States)

    Stokes, Leanne

    2013-03-01

    The P2X4 receptor is an ATP-gated ion channel expressed in neurons, endothelia and immune cells. Plasma membrane expression of P2X4 is regulated by dynamin-dependent endocytosis, and this study identifies a Rab5-dependent pathway of receptor internalisation. Expression of Rab5 constructs altered the distribution of P2X4 in HEK-293 cells, and both constitutive internalisation and agonist-induced desensitisation of P2X4 were increased by co-expression of wild-type Rab5 or constitutively active Rab5 (Q79L). Expression of inactive dynamin K44A and Rab5 S34N constructs abolished agonist-induced desensitisation, suggesting internalisation as the underlying mechanism. Blocking P2X4 internalisation in this way also abolished potentiation of ATP-induced currents by the allosteric modulator ivermectin. This suggests that the dynamin-Rab5 internalisation pathway is essential for the ivermectin potentiation effect. In agreement with this hypothesis, the co-expression of wild-type dynamin, wild-type Rab5 or active Rab5 (Q79L) could increase the potentiation of the ATP-induced P2X4 response by ivermectin. These findings highlight Rab5 GTPase as a key regulator of P2X4 receptor cell surface expression and internalisation.

    The aim of this study was to demonstrate that flow cytometry and confocal microscopy could be applied in a complementary manner to analyse the internalisation of polymeric nanosensors in mesenchymal stem cells (MSC). The two techniques are able to provide en masse data analysis of nanosensors from large cell populations and detailed images of intracellular nanosensor localisation, respectively. The polyacrylamide nanosensors used in this investigation had been modified to contain free amine groups which were subsequently conjugated to Tat peptide, which acted as a delivery vector for nanosensor internalisation. Flow cytometry was used to confirm the health of MSC culture and assess the impact of nanosensor internalisation. MSC were characterised using fluorescently tagged CD cell surface markers that were also used to show that nanosensor internalisation did not negatively impact on MSC culture. Additionally it was shown that flow cytometry can be used to measure fluorophores located both on the cell surface and internalised within the cell. Complementary data was obtained using confocal microscopy to confirm nanosensor internalisation within MSC.

    Photochemical Internalisation (PCI) is a novel drug delivery technology in which low dose photodynamic therapy (PDT) can selectively rupture endo/lysosomes by light activation of membrane-incorporated photosensitisers, facilitating intracellular drug release in the treatment of cancer. For PCI to be developed further, it is important to understand whether nerve damage is an impending side effect when treating cancers within or adjacent to nervous system tissue. Dorsal root ganglion (DRG) neurons and their associated satellite glia were subjected to PCI treatment in a 3D co-culture system following incubation with photosensitisers: meso-tetraphenylporphine (TPPS 2a ) or tetraphenylchlorin disulfonate (TPCS 2 a) and Bleomycin. Results from the use of 3D co-culture models demonstrate that a cancer cell line PCI30 and satellite glia were more sensitive to PCI than neurons and mixed glial cells, athough neurite length was affected. Neurons in culture survived PCI treatment under conditions sufficient to kill tumour cells, suggesting cancers within or adjacent to nervous system tissue could be treated with this novel technology.

  10. Agonist-induced internalisation of the glucagon-like peptide-1 receptor is mediated by the Gαq pathway.

    2015-01-01

    The glucagon-like peptide-1 receptor (GLP-1R) is a G-protein-coupled receptor (GPCR) and an important target in the treatment of type 2 diabetes mellitus (T2DM). Upon stimulation with agonist, the GLP-1R signals through both Gαs and Gαq coupled pathways to stimulate insulin secretion. The agonist-induced GLP-1R internalisation has recently been shown to be important for insulin secretion. However, the molecular mechanisms underlying GLP-1R internalisation remain unknown. The aim of this study was to determine the role of GLP-1R downstream signalling pathways in its internalisation. Agonist-induced human GLP-1R (hGLP-1R) internalisation and activity were examined using a number of techniques including immunoblotting, ELISA, immunofluorescence and luciferase assays to determine cAMP production, intracellular Ca(2+) accumulation and ERK phosphorylation. Agonist-induced hGLP-1R internalisation is dependent on caveolin-1 and dynamin. Inhibition of the Gαq pathway but not the Gαs pathway affected hGLP-1R internalisation. Consistent with this, hGLP-1R mutant T149M and small-molecule agonists (compound 2 and compound B), which activate only the Gαs pathway, failed to induce internalisation of the receptor. Chemical inhibitors of the Gαq pathway, PKC and ERK phosphorylation significantly reduced agonist-induced hGLP-1R internalisation. These inhibitors also suppressed agonist-induced ERK1/2 phosphorylation demonstrating that the phosphorylated ERK acts downstream of the Gαq pathway in the hGLP-1R internalisation. In summary, agonist-induced hGLP-1R internalisation is mediated by the Gαq pathway. The internalised hGLP-1R stimulates insulin secretion from pancreatic β-cells, indicating the importance of GLP-1 internalisation for insulin secretion. Copyright © 2014 Elsevier Inc.

    Endocytosis plays a crucial role in receptor signalling. VEGFR2 (also known as KDR) and its ligand VEGFA are fundamental in neovascularisation. However, our understanding of the role of endocytosis in VEGFR2 signalling remains limited. Despite the existence of diverse internalisation routes, the only known endocytic pathway for VEGFR2 is the clathrin-mediated pathway. Here, we show that this pathway is the predominant internalisation route for VEGFR2 only in the absence of ligand. Intriguingly, VEGFA induces a new internalisation itinerary for VEGFR2, the pathway of macropinocytosis, which becomes the prevalent endocytic route for the receptor in the presence of ligand, whereas the contribution of the clathrin-mediated route becomes minor. Macropinocytic internalisation of VEGFR2, which mechanistically is mediated through the small GTPase CDC42, takes place through macropinosomes generated at ruffling areas of the membrane. Interestingly, macropinocytosis plays a crucial role in VEGFA-induced signalling, endothelial cell functions in vitro and angiogenesis in vivo, whereas clathrin-mediated endocytosis is not essential for VEGFA signalling. These findings expand our knowledge on the endocytic pathways of VEGFR2 and suggest that VEGFA-driven internalisation of VEGFR2 through macropinocytosis is essential for endothelial cell signalling and angiogenesis. © 2016.

    Children with intellectual disability (ID) are at heightened risk for developing other psychological disorders, including internalising disorders. Anxiety and depression have been shown to be familial, and parenting is a contributing factor to the development of these disorders. To extend this research, we examined the extent to which mother and father depression and negative, unsupportive parenting related to child internalising behaviour problems, in children with ID or with typical development (TD). Participants were 156 mother and father dyads and their children, assessed at ages 4 and 5 years. We examined parent (mother and father) and child delay status (ID and TD) in relation to measures of both observed and self-reported unsupportive, negative parenting. Utilising moderation models, we examined the relationship between parental depression, unsupportive/negative parenting and child internalising behaviour problems. Unsupportive, negative parenting differed based on parent gender and child delay status. In addition, father depression was a significant moderator of the relationship between unsupportive parenting and child internalising behaviour problems. Children with ID were found to be at higher risk of experiencing unsupportive, negative parenting than children with TD. Children of depressed fathers were especially vulnerable to developing internalising behaviour problems in an unsupportive parenting context. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

  16. Ingression-type cell migration drives vegetal endoderm internalisation in the Xenopus gastrula.

    2017-08-10

    During amphibian gastrulation, presumptive endoderm is internalised as part of vegetal rotation, a large-scale movement that encompasses the whole vegetal half of the embryo. It has been considered a gastrulation process unique to amphibians, but we show that at the cell level, endoderm internalisation exhibits characteristics reminiscent of bottle cell formation and ingression, known mechanisms of germ layer internalisation. During ingression proper, cells leave a single-layered epithelium. In vegetal rotation, the process occurs in a multilayered cell mass; we refer to it as ingression-type cell migration. Endoderm cells move by amoeboid shape changes, but in contrast to other instances of amoeboid migration, trailing edge retraction involves ephrinB1-dependent macropinocytosis and trans -endocytosis. Moreover, although cells are separated by wide gaps, they are connected by filiform protrusions, and their migration depends on C-cadherin and the matrix protein fibronectin. Cells move in the same direction but at different velocities, to rearrange by differential migration.

    Recent studies indicate that hepatitis C virus (HCV) proteins can mediate innate immune response and inflammation in conjunctival fibroblasts which contributes to the pathology of dry eye condition associated with chronic HCV infection. The present study investigates the phagocytic potential of human conjunctival fibroblasts (HCFj) for HCV core protein. HCFj cells were incubated with HCV core antigen for different periods of time, and fluorescent micrographs were taken to observe protein internalisation. HCFj cells were capable of internalising HCV core antigen within 1 h; this gives an insight into another molecular mechanism which may contribute towards HCV-associated conjunctival inflammation.

    There has been a marked increase in divorce rates in most Western societies over the last 50 years. Relationship dissolution is associated with negative consequences both for adults and children, so it is important to understand the factors that help retain marital stability. The first aim of this prospective study was to identify risk factors for relationship dissolution in 18,523 couples in Norway, with a particular focus on individual dissatisfaction with the relationship. The second aim was to assess interaction effects between relationship dissatisfaction and other predictors of relationship dissolution. Pregnant women and their partners enrolled in the Norwegian Mother and Child Cohort study completed questionnaires during the pregnancy that asked about relationship dissatisfaction, strain, demographics, and other risk factors. The main outcome variable was relationship dissolution in the 39-month period from gestational week 30-36 months postpartum. Associations between the risk factors and relationship dissolution were estimated by logistic regression analysis. Except for younger female age, relationship dissatisfaction in women and lower education in men, were the strongest predictors of relationship dissolution. Another strong factor was women's persistent strain. No significant interaction effects were found between relationship dissatisfaction and the other variables in the analyses. Dissatisfaction with the relationship, in particular in women, and low male education are important predictors of relationship dissolution, although other factors are also related to dissolution. There are only few studies on relationship predictors of dissolution conducted in Europe, and the current study adds to this body of knowledge.

    To investigate whether secretion of human β-defensin 2 (HBD-2) is induced by bacillus Calmette-Guérin (BCG) and to determine whether HBD-2 affects BCG internalisation in bladder cancer cells. Reverse transcription-polymerase chain reaction analysis was used to determine whether HBD-2 mRNA increases after incubation with BCG. HBD-2 proteins in 5637 and T24 human bladder cancer cell lines were assayed by enzyme-linked immunosorbent assay. The internalisation rate was evaluated by double immunofluorescence assay and confocal microscopy to test the optimal dose of HBD-2 for BCG internalisation. We also investigated the difference in internalisation rates and cell viability between recombinant HBD-2 protein, anti-HBD-2 antibody, and HBD-2 plus anti-HBD-2 antibody pretreatments. BCG induced HBD-2 mRNA expression and HBD-2 production dose and time-dependently in bladder cancer cells and affected BCG internalisation. Pretreatment with recombinant HBD-2 protein lowered internalisation of BCG dose-dependently. Moreover, anti-HBD-2 antibody prevented the effect of HBD-2 on BCG internalisation in bladder cancer cells. The internalisation rate of BCG pretreated with anti-HBD-2 antibody was higher than that in the control in 5637 (P internalisation rate in cells pretreated with anti-HBD-2 antibody plus recombinant HBD-2 protein was higher than that in the control in 5637 (P internalisation, which plays an important role during the initiation and propagation of the immunotherapeutic response in bladder cancer cells. © 2013 The Authors.

    People living with HIV (PLWH) commonly report sleep disturbances which are associated with long-term health consequences, including disease progression. PLWH also experience internalised stigma as a result of their HIV status, which can be associated with increased loneliness and depression. Little attention focuses on the impact of these factors on sleep. Therefore, we examined whether internalised HIV-stigma was indirectly related to poorer sleep quality through higher levels of loneliness and depressive symptoms. 181 PLWH from across the United States completed an online survey. Main Study Measures: Internalised HIV-stigma was assessed using the HIV-Stigma Scale, loneliness was assessed using the UCLA-Loneliness Scale-Short Form, depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Index, and Sleep Quality was assessed using the Pittsburgh Sleep Quality Index. Internalised HIV-stigma was indirectly associated with poorer global sleep quality and daytime sleep dysfunction through both loneliness and depressive symptoms. PLWH who experience HIV-related stigma may experience greater feelings of loneliness, which are related to increased depressive symptoms and poorer sleep quality. Interventions focused on improving sleep in PLWH should focus on multiple factors that influence sleep, including psychosocial factors such as stigma, social isolation and depressive symptoms.

    Trafficking of the TrkA receptor after stimulation by NGF is of emerging importance in structural cells in the context of airway inflammatory diseases. We have recently reported the expression of functional TrkA receptors in human airway smooth muscle cells (HASMC). We have here studied the TrkA trafficking mechanisms in these cells. TrkA disappearance from the cell membrane was induced within 5 min of NGF (3pM) stimulation. Co-immunoprecipitation of clathrin-TrkA was revealed, and TrkA internalisation inhibited either by clathrin inhibitors or by siRNA inducing downregulation of endogenous clathrin. TrkA internalised receptors were totally degraded in lysosomes, with no recycling phenomenon. Newly synthesized TrkA receptors were thereafter re-expressed at the cell membrane within 10 h. TrkA re-synthesis was inhibited by blockade of clathrin-dependent internalisation, but not of TrkA receptors lysosomal degradation. Finally, we observed that NGF multiple stimulations progressively increased TrkA expression in HASMC, which was associated with an increase in NGF/TrkA-dependent proliferation. In conclusion, we show here the occurrence of clathrin-dependent TrkA internalisation and lysosomal degradation in the airway smooth muscle, followed by upregulated re-synthesis of functional TrkA receptors and increased proliferative effect in the human airway smooth muscle. This may have pathophysiological consequences in airway inflammatory diseases.

    2016-10-01

    The geldanamycin derivative 17-allylamino-17-demethoxygeldanamycin (17-AAG) is known to induce internalisation and degradation of the otherwise internalisation-resistant human epidermal growth factor receptor 2 (HER2) receptor. In the present study, 17-AAG was used to increase internalisation of the HER2-specific Affibody molecule ABY-025. The cellular redistribution of halogen-labelled 211 At-ABY-025 and radiometal-labelled 111 In-ABY-025 following treatment with 17-AAG was studied. 17-AAG treatment of SKOV-3 human ovarian carcinoma and SKBR-3 human breast carcinoma cells to some extent shifted the localisation of 111 In-ABY-025 from the cell surface to intracellular compartments in the two cell lines. ABY-025 labelled with the high-linear energy transfer α emitter 211 At was also internalised to a higher degree; however, due to its physiological properties, this nuclide was excreted faster. The results indicate that 17-AAG may be used to facilitate cell-specific intracellular localisation of a suitable cytotoxic or radioactive agent coupled to ABY-025 in HER2-overexpressing cells.

  8. A role for host cell exocytosis in InlB-mediated internalisation of Listeria monocytogenes.

    2017-11-01

    The bacterial surface protein InlB mediates internalisation of Listeria monocytogenes into human cells through interaction with the host receptor tyrosine kinase, Met. InlB-mediated entry requires localised polymerisation of the host actin cytoskeleton. Apart from actin polymerisation, roles for other host processes in Listeria entry are unknown. Here, we demonstrate that exocytosis in the human cell promotes InlB-dependent internalisation. Using a probe consisting of VAMP3 with an exofacial green fluorescent protein tag, focal exocytosis was detected during InlB-mediated entry. Exocytosis was dependent on Met tyrosine kinase activity and the GTPase RalA. Depletion of SNARE proteins by small interfering RNA demonstrated an important role for exocytosis in Listeria internalisation. Depletion of SNARE proteins failed to affect actin filaments during internalisation, suggesting that actin polymerisation and exocytosis are separable host responses. SNARE proteins were required for delivery of the human GTPase Dynamin 2, which promotes InlB-mediated entry. Our results identify exocytosis as a novel host process exploited by Listeria for infection. © 2017 John Wiley & Sons Ltd.

    We explored the effect of thin ideal internalisation, shame proneness and family criticism on disordered eating and suicidal intent in female Mexican adolescents. We studied a probabilistic sample of 2537 high school students in central Mexico, stratified by marginalisation status and migratory intensity. We used a generalised logistic regression model to estimate the odds of disordered eating and suicidal intent across scores for three predictors: Internalisation of the thin ideal, shame and family criticism. Disordered eating was reported by 4.2% (95% CI = 0.9-7.5%) and suicidal intent by 13.2% (95% CI = 12.0-14.4%) of girls. The unadjusted odds ratios of any disordered eating for thin ideal internalisation, shame proneness and familial criticism were 1.2, 1.1 and 3.2, respectively. The positive association between thin ideal internalisation and disordered eating remained even after controlling for shame proneness and familial criticism. The association of these variables with suicidal intent was weaker. Results support stronger effects for disordered eating than suicidal intent across the three unadjusted predictors. It also highlights the presence of the relationship of criticism and disordered eating in female adolescents from low and middle socio-economic backgrounds.

  13. Self-verification and bulimic symptoms: do bulimic women play a role in perpetuating their own dissatisfaction and symptoms?

    Science.gov (United States)

    Joiner, T E

    1999-09-01

    It is suggested that self-verification theory may provide insight as to why bulimic symptoms often persist for years, sometimes even despite intervention. In an effort to meet basic needs for self-confirmation, bulimic women may invite the very responses they fear (e.g., negative feedback about appearance), and thus propagate their symptoms. It was thus predicted that interest in negative feedback would be correlated with body dissatisfaction and bulimic symptoms, and that interest in negative feedback would serve as a risk factor for development of later symptoms, via the mediating effects of increased body dissatisfaction. Seventy-nine undergraduate women completed self-report assessments of interest in negative feedback, bulimic symptoms, and body dissatisfaction. Results supported the prediction that, despite serious concerns about body appearance, bulimic women were interested in the very feedback that would aggravate these concerns. Moreover, interest in negative feedback appeared to serve as a risk factor for development of later symptoms, via the mediating effects of increased body dissatisfaction. The clinical implications of these findings are discussed.

    Despite a paucity of research, adolescents living in rural areas appear to have a heightened risk for developing a mental health problem compared with their urban counterparts. The main objectives of this study were to contribute to building an evidence base of prevalence rates and determinants of internalising problems of adolescents in rural South Australia. A multidimensional Process Model was used as theoretical framework to enable an investigation of the various determinants from individual, family and community domains; specifically, the contribution of self-esteem, parental acceptance and elements of social capital at an individual level (ie participation in the local community and proactivity in a social context represented structural social capital, and feelings of trust and safety, and neighbourhood connections represented cognitive social capital). In this cross-sectional prospective study, a total of 388 Year 9 (2nd year of secondary school) students (208 females, 180 males) aged 13-15 years (mean age = 14.2 years) participated from 11 high schools within the Country Health South Australian area. These adolescents completed a battery of self-reported measures online at school. The results demonstrated that the adolescents experienced a 'normal' level of self-esteem and a 'moderate' level of perceived parental acceptance. The level of social capital was considered 'low' and the adolescents experienced a 'moderate' level of internalising symptoms. Based on the mean score of the Revised Child Anxiety & Depression Scales (RCADS), 25% of the adolescents experienced internalising symptoms ranging in severity from mild to severe, with no significant differences between males and females. Approximately 13% were considered above the clinical threshold, with 4% reporting experiencing severe symptoms. Relationships between all measures were investigated using Pearson product-moment correlations coefficients and associations between self-esteem, parental acceptance

    Adigbli, D K; MacRobert, A J

    2012-08-01

    Efficient delivery of therapeutic agents to subcellular targets is a major challenge in pharmacology. Physical properties including size and charge may adversely affect the cellular uptake of molecules, and consequently reduce the accessibility of intracellular targets. For example macromolecules, which do not pass freely through the phospholipid membrane, are internalised via endocytosis and subsequently retained in endosomes or lysosomes before enzymatic degradation or cell efflux. Photochemical internalisation (PCI) is a novel drug delivery technology based on light-activated release of biologically active compounds retained within endosomes/lysosomes. PCI is founded upon the principle of photodynamic therapy (PDT), which uses light to activate photosensitisers to ultimately produce reactive oxygen species (ROS) and cause local damage/cell death. In PCI, photosensitisers are selectively localised in endosomal/lysosomal membranes. PCI triggers membrane rupture facilitating release and delivery of endocytosed molecules to intracellular targets.

    A majority of gefitinib (IRESSA)-responsive tumours in non-small cell lung cancer have been found to carry mutations in ErbB1. Previously, it has been observed that internalisation-deficient ErbB1 receptors are strong drivers of oncogenesis. Using a computational model of ErbB1 trafficking and signalling, it is found that a deficiency in ErbB1 internalisation is sufficient to explain the observed signalling phenotype of these gefitinib-responsive ErbB1 mutants in lung cancer cell lines. Experimental tests confirm that gefitinib-sensitive cell lines with and without ErbB1 mutations exhibit markedly slower internalisation rates than gefitinib-insensitive cell lines. Moreover, the computational model demonstrates that reduced ErbB1 internalisation rates are mechanistically linked to upregulated AKT signalling. Experimentally it is confirmed that impaired internalisation of ErbB1 is associated with increased AKT activity, which can be blocked by gefitinib. On the basis of these experimental and computational results, it is surmised that gefitinib sensitivity is a marker of a reliance on AKT signalling for cell survival that may be brought about by impaired ErbB1 internalisation.

    We investigated whether cognitive ability (CA) may be a moderator of the relationship of parental socioeconomic position (SEP) with internalising and externalising problems in adolescents. We used data from two longitudinal cohort studies; the Avon Longitudinal Study of Parents and Children (ALSPAC) and the Tracking Adolescents' Individual Lives Survey (TRAILS). Indicators of SEP were mother's education and household income. CA was estimated with IQ scores, derived from the Wechsler Intelligence Scale for Children. Internalising and externalising problems were measured with the Strengths and Difficulties Questionnaire in ALSPAC and with the Child Behavior Checklist in TRAILS. Logistic regression analyses were used to estimate the relative index of inequality (RII) for each outcome; the RII provides the odds ratio comparing the most to least deprived for each measure of SEP. In fully adjusted models an association of mother's education with externalising problems was observed [ALSPAC RII 1.42 (95%CI: 1.01-1.99); TRAILS RII 2.21 (95%CI: 1.37-3.54)], and of household income with internalising and externalising problems [pooled ALSPAC and TRAILS internalising RII 1.30 (95%CI: 0.99-1.71); pooled ALSPAC and TRAILS externalising RII 1.38 (95%CI: 1.03-1.84)]. No consistent associations were observed between mother's education and internalising problems. Results of stratified analyses and interaction-terms showed no evidence that CA moderated the association of SEP with internalising or externalising problems.

    Increased expression of the connective tissue polysaccharide hyaluronan (HA) in the renal corticointerstitium is associated with progressive renal fibrosis. Numerous studies have demonstrated involvement proximal tubular epithelial cells in the fibrotic process and in the current study we have characterised their expression of the HA receptor, CD44, and examined changes in CD44 expression and function in response to either IL-1beta or glucose. Characterisation of CD44 splice variant expression was carried out in primary cultures of human proximal tubular cells (PTC) and HK2 cells. Binding and internalisation HA was examined by addition of exogenous of fluorescein-HA (fl-HA), and expression of CD44 examined by immunoblot analysis and flow cytometry. Alteration in "functional" CD44 was determined by immunoprecipitation of CD44 following stimulation in the presence of fl-HA. PTC, both primary culture and the PTC cell line, HK2, express at least 5 CD44 splice variants, the expression of which are not altered by addition of either IL-1beta or 25mM D-glucose. Addition of either stimulus increased cell surface binding and internalisation of fl-HA and increased expression of functionally active CD44. Increased binding and internalisation of fl-HA, was blocked by anti-CD44 antibody, and by the inhibition of O-glycosylation. The data demonstrate that stimuli inducing PTC HA synthesis also regulate PTC-HA interactions. Furthermore increased HA binding and internalisation is the result of post-translational modification of CD44 by O-glycosylation, rather than by alteration in expression of CD44 at the cell surface, or by alternate use of CD44 splice variants.

    Porous protein cages are supramolecular protein self-assemblies presenting pores that allow the access of surrounding molecules and ions into their core in order to store and transport them in biological environments. Protein cages' pores are attractive channels for the internalisation of inorganic nanoparticles and an alternative for the preparation of hybrid bioinspired nanoparticles. However, strategies based on nanoparticle transport through the pores are largely unexplored, due to the difficulty of tailoring nanoparticles that have diameters commensurate with the pores size and simultaneously displaying specific affinity to the cages' core and low non-specific binding to the cages' outer surface. We evaluated the specific internalisation of single small gold nanoparticles, 3.9 nm in diameter, into porous protein cages via affinity binding. The E2 protein cage derived from the Geobacillus stearothermophilus presents 12 pores, 6 nm in diameter, and an empty core of 13 nm in diameter. We engineered the E2 protein by site-directed mutagenesis with oligohistidine sequences exposing them into the cage's core. Dynamic light scattering and electron microscopy analysis show that the structures of E2 protein cages mutated with bis- or penta-histidine sequences are well conserved. The surface of the gold nanoparticles was passivated with a self-assembled monolayer made of a mixture of short peptidols and thiolated alkane ethylene glycol ligands. Such monolayers are found to provide thin coatings preventing non-specific binding to proteins. Further functionalisation of the peptide coated gold nanoparticles with Ni2+ nitrilotriacetic moieties enabled the specific binding to oligohistidine tagged cages. The internalisation via affinity binding was evaluated by electron microscopy analysis. From the various mutations tested, only the penta-histidine mutated E2 protein cage showed repeatable and stable internalisation. The present work overcomes the limitations of currently

  7. The relationship between internalising symptom development and academic attainment in early adolescence.

    Full Text Available Evidence for the longitudinal associations between internalising symptom development and academic attainment is sparse and results from existing studies are largely inconclusive. The approaches that have been used in existing studies examining this relationship have in common the limitation of grouping together all individuals in the sample which makes the assumption that the relationship between time, symptoms and attainment across all individuals is the same. The current study aimed to use heterogeneous trajectories of symptom development to examine the longitudinal associations between internalising symptom development and change in academic attainment over a three years period in early adolescence, a key period for internalising symptom development. Internalising symptoms were assessed for 3 consecutive years in a cohort from age 11-14 years (n = 2647, mean age at T1 = 11.7 years. National standardised test scores prior to the first wave and subsequent to the last wave were used as measures of academic attainment. Heterogeneous symptom development trajectories were identified using latent class growth analysis and socio-demographic correlates, such as gender, SES and ethnicity, of the different trajectory groupings were investigated. Derived trajectory groupings were examined as predictors of subsequent academic attainment, controlling for prior attainment. Results demonstrate that symptom trajectories differentially predicted change in academic attainment with increasing trajectories associated with significantly worse academic outcomes when compared to pupils with low levels of symptoms in all waves. Hence, a trajectory based approach provides a more nuanced breakdown of complexities in symptom development and their differential relationships with academic outcomes and in doing so helps clarify the longitudinal relationship between these two key domains of functioning in early adolescence.

  8. Adenylate cyclase toxin promotes internalisation of integrins and raft components and decreases macrophage adhesion capacity.

    Full Text Available Bordetella pertussis, the bacterium that causes whooping cough, secretes an adenylate cyclase toxin (ACT that must be post-translationally palmitoylated in the bacterium cytosol to be active. The toxin targets phagocytes expressing the CD11b/CD18 integrin receptor. It delivers a catalytic adenylate cyclase domain into the target cell cytosol producing a rapid increase of intracellular cAMP concentration that suppresses bactericidal functions of the phagocyte. ACT also induces calcium fluxes into target cells. Biochemical, biophysical and cell biology approaches have been applied here to show evidence that ACT and integrin molecules, along with other raft components, are rapidly internalized by the macrophages in a toxin-induced calcium rise-dependent process. The toxin-triggered internalisation events occur through two different routes of entry, chlorpromazine-sensitive receptor-mediated endocytosis and clathrin-independent internalisation, maybe acting in parallel. ACT locates into raft-like domains, and is internalised, also in cells devoid of receptor. Altogether our results suggest that adenylate cyclase toxin, and maybe other homologous pathogenic toxins from the RTX (Repeats in Toxin family to which ACT belongs, may be endowed with an intrinsic capacity to, directly and efficiently, insert into raft-like domains, promoting there its multiple activities. One direct consequence of the integrin removal from the cell surface of the macrophages is the hampering of their adhesion ability, a fundamental property in the immune response of the leukocytes that could be instrumental in the pathogenesis of Bordetella pertussis.

  10. CCR5 internalisation and signalling have different dependence on membrane lipid raft integrity.

    The chemokine receptor, CCR5, acts as a co-receptor for human immunodeficiency virus entry into cells. CCR5 has been shown to be targeted to cholesterol- and sphingolipid-rich membrane microdomains termed lipid rafts or caveolae. Cholesterol is essential for CCL4 binding to CCR5 and for keeping the conformational integrity of the receptor. Filipin treatment leads to loss of caveolin-1 from the membrane and therefore to a collapse of the caveolae. We have found here that sequestration of membrane cholesterol with filipin did not affect receptor signalling, however a loss of ligand-induced internalisation of CCR5 was observed. Cholesterol extraction with methyl-beta-cyclodextrin (MCD) reduced signalling through CCR5 as measured by release of intracellular Ca(2+) and completely abolished the inhibition of forskolin-stimulated cAMP accumulation with no effect on internalisation. Pertussis toxin (PTX) treatment inhibited the intracellular release of calcium that is transduced via Galphai G-proteins. Depletion of cholesterol destroyed microdomains in the membrane and switched CCR5/G-protein coupling to a PTX-independent G-protein. We conclude that cholesterol in the membrane is essential for CCR5 signalling via the Galphai G-protein subunit, and that integrity of lipid rafts is not essential for effective CCR5 internalisation however it is crucial for proper CCR5 signal transduction via Galphai G-proteins.

    The uptake of influenza A viruses (IAV) into cells represents an attractive antiviral drug target, e.g., by interfering with essential cellular or viral entry factors. So far, this process could only be studied by time-consuming microscopical methods. Thus, there is a lack of rapid and easy assay systems to monitor viral entry. Here, we describe a rapid procedure to analyse internalisation of IAV via Western blot detection of virion-associated matrix protein (M1), the most abundant protein within the viral particle. The assay is broadly applicable and detects different virus strains of various subtypes. As a proof of principle, treatment of cells with various known or presumed entry inhibitors resulted in reduced M1 levels. Removal of sialic acids, the receptors for IAV, led to a complete loss of the M1 signal, indicating that virus internalisation can be monitored already at the stage of attachment. Prevention of endosomal acidification resulted in a delayed degradation of M1 indicative of IAV particles trapped in endosomes. Thus, early detection of the virus-associated M1 protein is a rapid method to monitor different steps of influenza virus internalisation and has potential for application as a screening method for drugs that interfere with the uptake of IAV.

    To analyse the mechanisms of PAR-1 internalisation, we constructed several PAR-1 mutants and stably expressed them in CHO cells. Our study shows that the Ser(306)-->Ala mutation (S306A), which eliminates a potential site of phosphorylation by PKC in the third intracellular loop of PAR-1, did not change the rate of phosphorylation but reduced the rate of thrombin-induced internalisation of the PAR-1 mutant (58 versus 78% of membrane PAR-1 in 15 min, pinternalisation upon activation. This deletion also inhibited the PMA-induced and the agonist-independent internalisation of the receptor. The Tyr(371)--> Ala mutation (Y371A), in a NPXXY motif of the seventh transmembrane domain of the receptor had no effect on the receptor behaviour. Our results indicate that both the C-tail and the third intracellular loop are involved in PAR-1 internalisation induced by thrombin while only the C-tail plays a role in the PMA-induced and in the agonist-independent PAR-1 internalisation.

    Bacterial infection of the urinary tract is a common clinical problem with E. coli being the most common urinary pathogen. Bacterial uptake into epithelial cells is increasingly recognised as an important feature of infection. Bacterial virulence factors, especially fimbrial adhesins, have been conclusively shown to promote host cell invasion. Our recent study reported that C3 opsonisation markedly increases the ability of E. coli strain J96 to internalise into human proximal tubular epithelial cells via CD46, a complement regulatory protein expressed on host cell membrane. In this study, we further assessed whether C3-dependent internalisation by human tubular epithelial cells is a general feature of uropathogenic E. coli and investigated features of the bacterial phenotype that may account for any heterogeneity. In 31 clinical isolates of E. coli tested, C3-dependent internalisation was evident in 10 isolates. Type 1 fimbriae mediated-binding is essential for C3-dependent internalisation as shown by phenotypic association, type 1 fimbrial blockade with soluble ligand (mannose) and by assessment of a type 1 fimbrial mutant. we propose that efficient internalisation of uropathogenic E. coli by the human urinary tract depends on co-operation between type 1 fimbriae-mediated adhesion and C3 receptor -ligand interaction.

    Little is known on long-term consequences of poor social relationships in adulthood. The study aimed to examine associations between social relationships at age 30 and internalising symptoms at age 42. Data was drawn from four waves of the Northern Swedish cohort (n = 1001, 94 % response rate). The outcome internalising symptoms was measured by a composite index of depressiveness and anxiety. A cumulative measure was constructed to reflect various aspects of social relationships. Multivariate ordinal logistic regressions were used, controlling for socioeconomic indicators and previous level of internalising symptoms. An accumulation of poor social relationships indicators at age 30 is related to internalising symptoms at age 42 in women (OR 1.30; CI 1.11-1.52) and men (OR 1.17; CI 1.02-1.36). The associations remained significant after adjustment for covariates. Poor quality of social relationships at age 30 can predict internalising symptoms 12 years later in both men and women even when previous mental health as well as financial disadvantage is accounted for. More research is required to further examine pathways and mechanisms as well as suitable interventions.

    At a time when there is growing concern about the person-power shortages in occupational therapy, there is a need to address reasons why therapists leave the job market. Two job-related reasons for attrition are burnout and job dissatisfaction. The burnout phenomenon occurs as a result of personnel shortages, high-stress demands on therapists, the severity and complexity of client's problems, and the therapist's own ''worker personality.'' Bureaucratic constraints, limited advancement, issues related to a profession which is made up predominantly of women, lack of autonomy, and type of management and supervision are factors that contribute to job dissatisfaction. Occupational therapy managers can consider the causes of burnout and job dissatisfaction and initiate resources to retain therapists. Managers can increase the job benefits, such as flexible working hours, take steps to reduce stress in the workplace, offer career laddering opportunities, and promote staff development. By identifying the causes for attrition and by addressing those causes, the threat of losing therapists from the work force may be averted. Respondents (n = 106) to a survey of occupational therapy managers indicated that job dissatisfaction, burnout, and attrition of registered occupational therapists were not major problems in their settings. They reported a variety of strategies to reduce job dissatisfaction, burnout, and attrition. When these problems were present, managers cited bureaucratic red tape, lack of opportunity for advancement, and increasing role demands as contributing factors.

    Cellular internalisation of industrial engineered nanoparticles is undesired and a reason for concern. Here we investigated and compared the ability of seven different mammalian cell cultures in vitro to incorporate six kinds of engineered nanoparticles, focussing on the role of cell type and particle properties in particle uptake. Uptake was examined using light and electron microscopy coupled with energy dispersive X-ray spectroscopy (EDX) for particle element identification. Flow cytometry was applied for semi-quantitative analyses of particle uptake and for exploring the influence on uptake by the phagocytosis inhibitor Cytochalasin D (CytoD). All particles studied were found to enter each kind of cultured cells. Yet, particles were never found within cell nuclei. The presence of the respective particles within the cells was confirmed by EDX. Live-cell imaging revealed the time-dependent process of internalisation of technical nanoparticles, which was exemplified by tungsten carbide particle uptake into the human skin cells, HaCaT. Particles were found to co-localise with lysosomal structures within the cells. The incorporated nanoparticles changed the cellular granularity, as measured by flow cytometry, already after 3 h of exposure in a particle specific manner. By correlating particle properties with flow cytometry data, only the primary particle size was found to be a weakly influential property for particle uptake. CytoD, an inhibitor of actin filaments and therewith of phagocytosis, significantly inhibited the internalisation of particle uptake in only two of the seven investigated cell cultures. Our study, therefore, supports the notion that nanoparticles can enter mammalian cells quickly and easily, irrespective of the phagocytic ability of the cells.

    The glucagon-like peptide receptor (GLP-1R), which is a G-protein coupled receptor (GPCR), signals through both Gαs and Gαq coupled pathways and ERK phosphorylation to stimulate insulin secretion. The aim of this study was to determine molecular details of the effect of small molecule agonists, compounds 2 and B, on GLP-1R mediated cAMP production, intracellular Ca2+ accumulation, ERK phosphorylation and its internalisation. In human GLP-1R (hGLP-1R) expressing cells, compounds 2 and B induced cAMP production but caused no intracellular Ca2+ accumulation, ERK phosphorylation or hGLP-1R internalisation. GLP-1 antagonists Ex(9-39) and JANT-4 and the orthosteric binding site mutation (V36A) in hGLP-1R failed to inhibit compounds 2 and B induced cAMP production, confirming that their binding site distinct from the GLP-1 binding site on GLP-1R. However, K334A mutation of hGLP-1R, which affects Gαs coupling, inhibited GLP-1 as well as compounds 2 and B induced cAMP production, indicating that GLP-1, compounds 2 and B binding induce similar conformational changes in the GLP-1R for Gαs coupling. Additionally, compound 2 or B binding to the hGLP-1R had significantly reduced GLP-1 induced intracellular Ca2+ accumulation, ERK phosphorylation and hGLP-1R internalisation. This study illustrates pharmacology of differential activation of GLP-1R by GLP-1 and compounds 2 and B.

    Patients with schizophrenia sometimes internalise social stigma associated to mental illness, and they develop personal stigma. Personal stigma includes self-stigma (internalisation of negative stereotypes), perceived stigma (perception of rejection), and experienced stigma (experiences of discrimination). Personal stigma is linked with a poorer treatment adherence, and worst social functioning. For this reason, it is important to have good measurements of personal stigma. One of the most frequently used measurements is the Internalised Stigma of Mental Illness (ISMI) scale. There is a Spanish version of the scale available, although its psychometric properties have not been studied. The main aim of this study is to analyse the psychometric properties of a new Spanish version of the ISMI scale. The new version was translated as Estigma Interiorizado de Enfermedad Mental (EIEM). Internal consistency and test-retest reliability were calculated in a sample of 69 patients with a diagnosis of schizophrenia or schizoaffective disorder. The rate of patients showing personal stigma was also studied, as well as the relationship between personal stigma and sociodemographic and clinical variables. The adapted version obtained good values of internal consistency and test-retest reliability, for the total score of the scale (0.91 and 0.95 respectively), as well as for the five subscales of the EIEM, except for the Stigma Resistance subscale (Cronbach's alpha 0.42). EIEM is an appropriate measurement tool to assess personal stigma in a Spanish population with severe mental disorder, at least in those with a diagnosis of schizophrenia or schizoaffective disorder.

    2010-11-17

    Recently, several new and non-invasive methods have been introduced for the treatment of skin cancers. Topical creams using the immune modulator imiquimod or the COX inhibitor diclofenac (with hyaluronic acid) are now registered for use against neoplasms such as basal or squamous cell carcinoma. Another modern treatment option is photodynamic therapy (PDT). A refined version of PDT, namely photochemical internalisation, is currently subject to a first clinical trial in patients with osteosarcoma, squamous cell carcinoma, head and neck cancer as well as adenocarcinoma of the breast. Preliminary results from this trial suggest that PCI seems to be a promising treatment.

    In this comparative study, the impact of two microbial protective mechanisms against simulated UVA disinfection was assessed by using protocols previously developed for UVC disinfection assays. (i) The impact of natural microorganism aggregation and attachment to particles was assessed by targeting total coliform bacteria in natural surface water samples. (ii) The impact of bacteria internalisation by zooplankton was assessed by using C. elegans nematodes as a model host and E. coli as a bacterial target for UVA inactivation. Dispersion of natural aggregates by blending prior to UVA exposure was shown to enhance the inactivation rate of total coliforms as compared to untreated raw water. Removal of particles by an 8-microm membrane filtration did not improve UVA disinfection efficiency. Twenty-four per cent of the highest applied UVA fluence was found to reach internalised E. coli in nematodes. Both aggregation and internalisation showed similar impact as protective mechanisms against UVA and UVC bacterial inactivation.

    It is acknowledged that people with a schizophrenia-spectrum diagnosis experience higher levels of stigma compared to any other mental health diagnosis. As a consequence, their experience of internalised stigma is likely to be the most detrimental and pervasive. Internalised stigma interventions have shown some benefits in those who experience serious mental illness including those with a schizophrenia-spectrum diagnosis. A systematic narrative review and meta-analysis were conducted examining the efficacy of internalised stigma interventions for people with a schizophrenia-spectrum diagnosis. Randomised Controlled Trials, controlled trials, and cohort studies were included and assessed against quality criteria. The search identified 12 studies; 7 randomised controlled trials, 3 cohort studies and 2 controlled trials. A variety of psychosocial interventions were utilised with the majority employing Cognitive Behaviour Therapy (CBT), psychoeducation and social skills training. The core outcomes used to examine the efficacy of the intervention were internalised stigma, self-esteem, empowerment, and functioning. The meta-analysis revealed an improvement in internalised stigma favouring the internalised stigma intervention but was not significant (5 RCTs, n=200). Self-efficacy and insight were significantly improved favouring the internalised stigma intervention. Internalised stigma interventions show promise in those with schizophrenia-spectrum diagnoses. Existing interventions have demonstrated small effects and employed small samples. Large scale RCTs are required to further develop the evidence base of more targeted interventions.

  7. Being a gay man in Turkey: internalised sexual prejudice as a function of prevalent hegemonic masculinity perceptions.

    Science.gov (United States)

    Eslen-Ziya, Hande; Koc, Yasin

    2016-07-01

    This paper examines expressions and experiences of internalised sexual stigma with respect to definitions of masculinity and identity conflicts through a thematic analysis of life-history narratives of 14 self-identified gay men living in Turkey. The analysis reveals that internalised sexual prejudice emerges when widely accepted hegemonic masculinity ideology is 'violated' by being gay. Participants' narratives indicate that their construction of masculinity is a vigorous process established via encounters with hegemonic masculinity. Findings are discussed in the context of the relevant literature and in relation to Turkish culture's traditional understanding of gender and gender roles.

    Characterising the mechanisms underpinning caspase-independent programmed cell death (CI-PCD) induction by uncross-linked rituximab in B-cells may positively impact upon the treatment of disease states in which the classical apoptotic pathway is disabled. The necessity of rituximab internalisation for CI-PCD induction was investigated by flow cytometry and confocal microscopy in human BL cell lines with (e.g. Mutu I) and without (Mutu III) susceptibility to rituximab-induced killing. Flow cytometry demonstrated small, significant and similar amounts of rituximab internalisation by Mutu I cells after 1, 2, 4 and 24 h (p internalisation (p = 0.02, n = 5 and p = 0.0002, n = 6, respectively) in Mutu I cells, but confocal microscopy showed no correlation between internalised rituximab and phosphatidylserine exposure. We conclude that rituximab internalisation is not essential for CI-PCD induction in BL cell lines.

    The opioid receptor system in the central nervous system controls a number of physiological processes, most notably pain. However, most opioids currently available have a variety of side-effects as well as exhibiting tolerance. Tolerance is most likely to be a complex phenomenon, however, the role of receptor internalisation is thought to play a crucial role. In this study, we examined the role of aromaticity in ligand-mediated receptor internalisation of the mu-opioid receptor (MOPR). These studies show that the amount of receptor internalisation may be dependant on the amphiphilicity of the ligand. Specifically, deletion of the C-terminus aromatic residues of endomorphin 1, particularly tryptophan reduces receptor-mediated internalisation whilst the addition of tryptophan within the enkephalin sequence increases receptor internalisation and decreases tolerance.

    Photochemical internalisation (PCI) is a site-specific technique for improving cellular delivery of macromolecular drugs. In this study, a cell penetrating peptide, containing the core HIV-1 Tat 48-57 sequence, conjugated with a porphyrin photosensitiser has been shown to be effective for PCI. Herein we report an investigation of the photophysical and photobiological properties of a water soluble bioconjugate of the cationic Tat peptide with a hydrophobic tetraphenylporphyrin derivative. The cellular uptake and localisation of the amphiphilic bioconjugate was examined in the HN5 human head and neck squamous cell carcinoma cell line. Efficient cellular uptake and localisation in endo/lysosomal vesicles was found using fluorescence detection, and light-induced, rupture of the vesicles resulting in a more diffuse intracellular fluorescence distribution was observed. Conjugation of the Tat sequence with a hydrophobic porphyrin thus enables cellular delivery of an amphiphilic photosensitiser which can then localise in endo/lysosomal membranes, as required for effective PCI treatment. PCI efficacy was tested in combination with a protein toxin, saporin, and a significant reduction in cell viability was measured versus saporin or photosensitiser treatment alone. This study demonstrates that the cell penetrating peptide-photosensitiser bioconjugation strategy is a promising and versatile approach for enhancing the therapeutic potential of bioactive agents through photochemical internalisation.

    Toxoplasma gondii is a common parasite of humans and animals, which is transmitted via oocysts in cat faeces or tissue cysts in contaminated meat. The robust oocyst and sporocyst walls protect the infective sporozoites from deleterious external attacks including disinfectants. Upon oocyst acquisition, these walls lose their integrity to let the sporozoites excyst and invade host cells following a process that remains poorly understood. Given the resistance of the oocyst wall to digestive enzymes and the ability of oocysts to cause parenteral infections, the present study investigated the possible contribution of macrophages in supporting sporozoite excystation following oocyst internalisation. By using single cell micromanipulations, real-time and time-point imaging techniques, we demonstrated that RAW macrophages could interact rapidly with oocysts and engulfed them by remodelling of their actin cytoskeleton. Internalised oocysts were associated to macrophage acidic compartments and showed evidences of wall disruption. Sporozoites were observed in macrophages containing oocyst remnants or in new macrophages, giving rise to dividing tachyzoites. All together, these results highlight an unexpected role of phagocytic cells in processing T. gondii oocysts, in line with non-classical routes of infection, and open new perspectives to identify chemical factors that lead to oocyst wall disruption under physiological conditions.

  12. Antibody drug conjugates and bystander killing: is antigen-dependent internalisation required?

    Science.gov (United States)

    Staudacher, Alexander H; Brown, Michael P

    2017-12-05

    Antibody drug conjugates (ADCs) employ the exquisite specificity of tumour-specific monoclonal antibodies (mAb) for the targeted delivery of highly potent cytotoxic drugs to the tumour site. The chemistry of the linker, which connects the drug to the mAb, determines how and when the drug is released from the mAb. This, as well as the chemistry of the drug, can dictate whether the drug can diffuse into surrounding cells, resulting in 'bystander killing'. Initially, any bystander killing mechanism of action of an ADC was understood to involve an essential sequence of steps beginning with surface antigen targeting, internalisation, intracellular linker cleavage, drug release, and diffusion of drug away from the targeted cell. However, recent studies indicate that, depending on the linker and drug combination, this mechanism may not be essential and ADCs can be cleaved extracellularly or via other mechanisms. In this minireview, we will examine the role of bystander killing by ADCs and explore the emerging evidence of how this can occur independently of internalisation.

    Andrew, Rachel; Tiggemann, Marika; Clark, Levina

    2016-09-01

    This study examined a range of predictors, based on previous theoretical models, of positive body image in young adult women. Participants were 266 women who completed an online questionnaire measuring body appreciation, activity participation, media consumption, perceived body acceptance by others, self-compassion, and autonomy. Potential mechanisms in predicting body appreciation assessed were self-objectification, social appearance comparison, and thin-ideal internalisation. Results indicated that greater perceived body acceptance by others and self-compassion, and lower appearance media consumption, self-objectification, social comparison, and thin-ideal internalisation were related to greater body appreciation. An integrated model showed that appearance media (negatively) and non-appearance media and self-compassion (positively) were associated with lower self-objectification, social comparison, and thin-ideal internalisation, which in turn related to greater body appreciation. Additionally, perceived body acceptance by others was directly associated with body appreciation. The results contribute to an understanding of potential pathways of positive body image development, thereby highlighting possible intervention targets. Copyright © 2016 Elsevier Ltd.

    Agonist exposure can cause internalisation of G-protein coupled receptors (GPCRs), which may be a part of desensitisation but also of cellular signaling. Previous methods to study internalisation have been tedious or only poorly quantitative. Therefore, we have developed and validated a quantitative method using a sphingosine-1-phosphate (S1P) receptor as a model. Because of a lack of suitable binding studies, it has been difficult to study S1P receptor internalisation. Using a N-terminal HisG-tag, S1P(1) receptors on the cell membrane can be visualised via immunocytochemistry with a specific anti-HisG antibody. S1P-induced internalisation was concentration dependent and was quantified using a microplate reader, detecting either absorbance, a fluorescent or luminescent signal, depending on the antibodies used. Among those, the fluorescence detection method was the most convenient to use. The relative ease of this method makes it suitable to measure a large number of data points, e.g. to compare the potency and efficacy of receptor ligands.

    The current study examined sociocultural correlates of body dissatisfaction and maladaptive eating attitudes among 74 South Asian American women. Participants completed measures assessing three forms of teasing--general appearance, weight/shape, and ethnic--as well as thin-ideal internalization, acculturation, cultural conflict, body dissatisfaction, and maladaptive eating attitudes. Results indicated that all three types of teasing and cultural conflict were significantly related to body dissatisfaction and maladaptive eating attitudes. Cultural conflict was found to mediate the relationship between ethnic teasing and body dissatisfaction. Neither thin-ideal internalization nor acculturation was significantly associated with either body dissatisfaction or maladaptive eating attitudes. However, body dissatisfaction was found to mediate the relationship between weight/shape teasing and maladaptive eating attitudes. Implications of these findings and possible future directions for research on South Asian American women are discussed. (c) 2007 APA, all rights reserved.

    2002-01-01

    The aim of integrating national power markets is to improve the overall efficiency thereby making a potential for reducing electricity prices. However, efficiency is not necessarily improved if external environmental protection costs are neglected. In this paper, we analyse the effects of regulating an integrated power market by using environmental producer taxes based on external production costs. The analysis is based on an empirical equilibrium model for the North European power market. The results show that internalising costs will increase electricity producer prices by 40-50% in the period from 1995 to 2020. Further, demand for electricity will be reduced by 10%. We conclude, however, that in order to achieve the national Kyoto targets of reducing CO 2 emissions, further regulation is needed, such as national CO 2 taxes or cost efficient mechanisms like tradeable permits and joint implementation.

    Photochemical internalisation (PCI) is a technique for improving cellular delivery of certain bioactive agents which are prone to sequestration within endolysosomes. There is a wide range of agents suitable for PCI-based delivery including toxins, oligonucleotides, genes and immunoconjugates which demonstrates the versatility of this technique. The basic mechanism of PCI involves triggering release of the agent from endolysosomes within the target cells using a photosensitiser which is selectively retained with the endolysosomal membranes. Excitation of the photosensitiser by visible light leads to disruption of the membranes via photooxidative damage thereby releasing the agent into the cytosol. This treatment enables the drugs to reach their intended subcellular target more efficiently and improves their efficacy. In this review we summarise the applications of this technique with the main emphasis placed on cancer chemotherapy. © 2015 The Authors. Published by Wiley Periodicals, Inc. on behalf of UICC.

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

    When applied extracellularly, myo-inositol hexakisphosphate (InsP6 ) and myo-inositol pentakisphosphate (InsP5 ) can inhibit the growth and proliferation of tumour cells. There is debate about whether these effects result from interactions of InsP6 and InsP5 with intracellular or extracellular targets. We synthesised FAM-InsP5 , a fluorescent conjugate of InsP5 that allows direct visualisation of its interaction with cells. FAM-InsP5 was internalised by H1229 tumour cells, a finding that supports earlier reports that externally applied inositol phosphates can-perhaps surprisingly-enter into cells. Close examination of the process of FAM-InsP5 uptake suggests a mechanism of non-receptor-mediated endocytosis, which is blocked at 4 °C and probably involves interaction of the ligand with the glycocalyx. However, our results are difficult to reconcile with antiproliferative mechanisms that require direct interactions of externally applied InsP5 or InsP6 with cytosolic proteins, because internalised FAM-InsP5 appears in lysosomes and apparently does not enter the cytoplasm. Studies using FAM-InsP5 are less difficult and time-consuming than experiments using InsP5 or InsP6 , a factor that allowed us to analyse cellular uptake across a range of human cell types, identifying strong cell-specific differences.

    This study aimed to highlight a statistic design to precisely engineer homogenous geometric copper nanoparticles (CuNPs) for enhanced intracellular drug delivery as a function of geometrical structure. CuNPs with a dual functionality comprising geometric attributes for enhanced cell uptake and exerting cytotoxic activity on proliferating cells were synthesized as a novel drug delivery system. This paper investigated the defined concentrations of two key surfactants used in the reaction to mutually control and manipulate nano-shape and optimisation of the geometric nanosystems. A statistical experimental design comprising a full factorial model served as a refining factor to achieve homogenous geometric nanoparticles using a one-pot method for the systematic optimisation of the geometric CuNPs. Shapes of the nanoparticles were investigated to determine the result of the surfactant variation as the aim of the study and zeta potential was studied to ensure the stability of the system and establish a nanosystem of low aggregation potential. After optimisation of the nano-shapes, extensive cellular internalisation studies were conducted to elucidate the effect of geometric CuNPs on uptake rates, in addition to the vital toxicity assays to further understand the cellular effect of geometric CuNPs as a drug delivery system. In addition to geometry; volume, surface area, orientation to the cell membrane and colloidal stability is also addressed. The outcomes of the study demonstrated the success of homogenous geometric NP formation, in addition to a stable surface charge. The findings of the study can be utilized for the development of a drug delivery system for promoted cellular internalisation and effective drug delivery. Copyright © 2017 Elsevier B.V.

    Bullying victimisation has been prospectively linked with mental health problems among children and adolescents in longitudinal studies in the developed world. However, research from the developing world, where adolescents face multiple risks to social and emotional development, has been limited by cross-sectional designs. This is the first longitudinal study of the psychological impacts of bullying victimisation in South Africa. The primary aim was to examine prospective relationships between bullying victimisation and internalising and externalising symptoms in South African youth. Secondary aims were to examine gender and age-related differences in experiences of bullying victimisation. Children and adolescents (10-17 years, 57 % female, n = 3,515) from high HIV-prevalent (>30 %) communities in South Africa were interviewed and followed-up 1 year later (97 % retention). Census enumeration areas were randomly selected from urban and rural sites in two provinces and door-to-door sampling included all households with a resident child/adolescent. Exposure to multiple experiences of bullying victimisation at baseline predicted internalising symptoms and conduct problems 1 year later. Additionally, baseline mental health scores predicted later bullying victimisation, demonstrating bi-directionality of relationships between bullying victimisation and mental health outcomes in this sample. Expected gender differences in physical, verbal, and relational bullying victimisation were evident and predicted declines in bullying victimisation over time were observed. In the developed world, school-based anti-bullying programmes have been shown to be effective in reducing bullying and victimisation. Anti-bullying programmes should be implemented and rigorously evaluated in South Africa, as this may promote improved mental health among South African children and adolescents.

    Full Text Available The objective of this research was to verify empirically that internalising externalities of private enterprises contributes to profitability on a long-term basis. One of the significant transitions of the economic environment globally at the beginning of this century has been the rapid economic growth of emerging countries. On the other hand, there is apprehension also about various social problems due to the rapid industrialisation of such emerging countries, or improvement in the living standard. Political-economist Malthus (1798 warned of such a drain on resources and energy, and the ravaging of the natural environment at the beginning of the nineteenth century. Present-day Malthusians warn of ruin because of the exhaustion of resources and environmental deterioration resulting from active business activity. This aims to tighten up regulations as "a governmental role" to the so-called "market failure." Mill (1848 introduced the concept of “stationary state” in the "philosophy of economics." On the other hand, Robert Solow (1956 highlighted the significance of technological progress as a factor of economic growth. In terms of the positive role of a private company, Porter et al. (2011 called it the strategy of shared-value creation. It is internalisation of the externality on a market transaction. In terms of research methodology, statistical verification was carried out based on the sustainability statement, the various publicity materials and the financial data released by each company. In conclusion, when private enterprises adopt sustainability activity positively, a consumer value, corporate value and social value are expanded cyclically.

    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.

    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.

    The authors examined the relationship between body dissatisfaction and self-image across the life span. A sample of 106 women between the ages of 20 and 65 years completed questionnaire measures of body dissatisfaction, body importance, cognitive control over the body, self-concept, and self-esteem. The authors found that body dissatisfaction and body importance did not differ among the groups of women who were younger, middle aged, and older. Although body dissatisfaction was related to self-concept and self-esteem for the entire sample, the strength of that relationship reduced with increasing age and increasing perceptions of cognitive control. The authors concluded that the cognitive strategies of women who were older protect their self-concept and self-esteem from the influence of body dissatisfaction.

    In order to gain better insight into the molecular events involved in the signal transduction generated through glucagon-like peptide-1 (GLP-1) receptors, we tested the effect of deletions and point mutations within the cytoplasmic tail of this receptor with a view to establishing relationships between signal transduction desensitisation and receptor internalisation. Wild-type and truncated (deletion of the last 27 amino acids (GLPR 435R) and deletion of 44 amino acids (GLPR 418R)) GLP-1 receptors bound the agonist with similar affinity. Deletion of the last 27 amino acids decreased the internalisation rate by 78%, while deletion of 44 amino acids containing all the phosphorylation sites hitherto described in this receptor decreased the internalisation rate by only 47%. Binding of the ligand to both receptors stimulated adenylyl cyclase. In contrast, deletion of the region containing amino acids 419 to 435 (GLPR 419delta435) increased the internalisation rate by 268%, and the replacement of EVQ(408-410) by alanine (GLPR A(408-410)) increased this process to 296%. In both receptors, the efficacy in stimulating adenylate cyclase was decreased. All the receptors studied were internalised by coated pits, except for the receptor with a deletion of the last 44 amino acids, which also had a faster resensitisation rate. Our findings indicate that the neighbouring trans-membrane domain of the carboxyl-terminal tail of the GLP-1 receptor contains sequence elements that regulate agonist-dependent internalisation and transmembrane signalling.

    Internalised shame and self-esteem have both been proposed to play an integral role in the relationship between stigma and its negative psychological sequelae in people who experience psychosis, but there has been little quantitative exploration to examine their roles further. The aim of this study was to examine the relationship of stigma (experienced and perceived) with emotional distress and recovery in psychosis, and to examine internalised shame and self-esteem as potential mediators. A total of 79 participants were included for the purposes of this study. Participants were administered a battery of assessment measures examining experienced and perceived stigma, internalised shame, self-esteem, depression, hopelessness, and personal recovery. Results illustrated that stigma (experienced and perceived) was significantly associated with internalised shame, low self-esteem, depression, hopelessness and poor personal recovery. Stigma (experienced and perceived) and its relationship with depression, hopelessness and personal recovery was mediated by both internalised shame and low self-esteem. In conclusion, stigma can have significant negative emotional consequences and impede recovery in people with psychosis. This may indicate that stigma needs to be addressed therapeutically for people with psychosis with a particular emphasis on addressing internalised shame and low self-esteem. Copyright © 2017.

    The occurrence of pathogens in the internal parts of vegetables is usually associated with irrigation water or contaminated soil and could pose risk to consumers as the internalised pathogens are unaffected by external washing. This study was carried out to assess the rate of internalisation of microbes in common Ghanaian vegetables. Standard microbiological methods were employed in microbial enumeration of vegetables collected at the market and farm levels, as well as irrigation water and soil samples. The overall mean counts of vegetables were 4.0 x 10(3) cfu g(-1); 8.1 x 10(2) cfu g(-1); 2.0 x 10(2) cfu g(-1); 3.5 x 10(2) cfu g(-1) for total bacteria, coliform counts, faecal coliform counts and yeast counts, respectively. The rate of internalisation of coliforms in vegetables irrigated with stream/well water was 2.7 times higher than those irrigated with pipe water. The mean coliform counts (4.7 x 10(7) cfu g(-1)) and faecal coliform counts (1.8 x 10(6) cfu g(-1)) of soil samples were similar to those of stream water suggesting both sources exerted similar contamination rates on the vegetables. Generally, there were no significant variations between the rates of internalisation of microbes at the market and farm levels at p vegetables mainly occurred at the farm level. The study has shown that microbial contamination of vegetables in Ghana is not limited to the external surface, but internal vegetable parts could harbour high microbial loads and pose risk to consumers. Safety practices associated with the commodity should therefore not be limited to external washing only. There is the additional need of heating vegetables to eliminate microbes both externally and internally before consumption.

    Internalisation and recycling of seven trans-membrane domain receptors is a critical regulatory event for their signalling. The mechanism(s) by which membrane progesterone receptor-α (mPRα) number is regulated on the cell surface is unclear. In this study, we investigated the cellular distribution of mPRα and mechanisms of mPRα trafficking using a cell line derived from a primary culture of human myometrial cells (M11) as an experimental model. RT-PCR and immunofluorescent analysis demonstrated expression of mPRα in M11 cells with mPRα primarily distributed on the cell surface under basal conditions. For the first time, plasma membrane localisation of mPRα was confirmed using immuno-gold transmission electron microscopy. Stimulation of M11 cells with progesterone (P4, 100 nM) resulted in internalisation of mPRα from the plasma membrane to the cytoplasm (10 min) and subsequent partial translocation back to the cell surface (20 min). We investigated potential endocytotic pathways involved in trafficking of mPRα after its internalisation. Partial co-localisation of clathrin with mPRα was obvious after 10 min of P4 treatment. Of note, chlorpromazine (inhibitor of clathrin-mediated pathway) inhibited the endocytosis of mPRα, whereas treatment with nystatin (inhibitor of caveolae-mediated pathway) did not affect internalisation. Collectively, these data suggest that mPRα is expressed on the cell surface of M11 cells and undergoes endocytosis after P4 stimulation primarily via a clathrin-mediated pathway.

    Absorption of iron occurs by duodenal enterocytes, involving uptake by the divalent metal transporter-1 (DMT1) and release by ferroportin. Ferroportin responds to the hepatocyte-produced 25-amino-acid-peptide hepcidin-25 by undergoing internalisation to late endosomes that impair iron release. Ferroportin is also expressed on the apical membrane of polarised Caco-2 cells, rat intestinal cells and in IEC-6 cells (an intestinal epithelial cell line). A blocking antibody to ferroportin also impairs the uptake, but not the release, of iron. In this study IEC-6 cells were used to study the mechanism of impairment or recovery from impairment produced by the blocking antibody and the fate of DMT1 and ferroportin. Uptake of 1 muM Fe(II) was studied by adding the antibody from time 0 and after adding or removing the antibody once a steady state had been reached. Surface binding, maximum iron transport rate V(max) and transporter affinity (K(m)) were measured after impairment of iron uptake. Ferroportin and DMT1 distribution were assessed by immunofluorescence microscopy. Antibody-mediated impairment, or recovery from impairment, of Fe(II) uptake occurred within minutes. Impairment was lost when the antibody was combined with the immunizing peptide. DMT1 and ferroportin undergo internalisation to late endosomes and, in the presence of the antibody, augmented internalisation of DMT1 and ferroportin caused swelling of late endosomes. Surface binding of Fe(II) and iron transport V(max) were reduced by 50%, indicating that the antibody removed membrane-bound DMT1. The ferroportin antibody induced rapid turnover of membrane ferroportin and DMT1 and its internalisation to late endosomes, resulting in impaired Fe(II) uptake.

    The glucagon-like peptide-1 (GLP-1) receptor (GLP-1R), an important drug target in the treatment of type 2 diabetes, is a G-protein coupled receptor (GPCR) that mediates insulin secretion by GLP-1. The N-terminus controls GLP-1R biosynthetic trafficking to the cell surface but the C-terminus involvement in that trafficking is unknown. The aim of this study was to identify distinct regions within the C-terminal domain required for human GLP-1R (hGLP-1R) cell surface expression, activity and internalisation using a number of C-terminal deletions and site-directed mutations. The results of this study revealed that the residues 411-418 within the C-terminal domain of the hGLP-1R are critical in targeting the newly synthesised receptor to the plasma membrane. The residues 419-430 are important for cAMP producing activity of the receptor, most likely by coupling to Gαs. However, the residues 431-450 within the C-terminus are essential for agonist-induced hGLP-1R internalisation. In conclusion, these findings demonstrate the hGLP-1R has distinct regions within the C-terminal domain required for its cell surface expression, activity and agonist-induced internalisation.

    The Global MARKAL-Model (GMM), a multi-regional 'bottom-up' partial equilibrium model of the global energy system with endogenous technological learning, is used to address impacts of internalisation of external costs from power production. This modelling approach imposes additional charges on electricity generation, which reflect the costs of environmental and health damages from local pollutants (SO 2 , NO x ) and climate change, wastes, occupational health, risk of accidents, noise and other burdens. Technologies allowing abatement of pollutants emitted from power plants are rapidly introduced into the energy system, for example, desulphurisation, NO x removal, and CO 2 scrubbers. The modelling results indicate substantial changes in the electricity production system in favour of natural gas combined cycle, nuclear power and renewables induced by internalisation of external costs and also efficiency loss due to the use of scrubbers. Structural changes and fuel switching in the electricity sector result in significant reduction of emissions of both local pollution and CO 2 over the modelled time period. Strong decarbonisation impact of internalising local externalities suggests that ancillary benefits can be expected from policies directly addressing other issues then CO 2 mitigation. Finally, the detailed analysis of the total generation cost of different technologies points out that inclusion of external cost in the price of electricity increases competitiveness of non-fossil generation sources and fossil power plants with emission control

The study included 736 women (≥ 18 years. Anthropometric variables (weight, height, waist circumference were collected for the determination of body mass index, waist-height ratio, and conicity index. Body image perception was evaluated using a nine-body silhouette scale. The prevalence of body image dissatisfaction was 73% (dissatisfaction due to excess weight = 67.4%; dissatisfaction due to thinness = 5.6%. Overweight women (PR=1.34; 95%CI=1.23-2.49, p<0.001 and women with an inadequate conicity index (PR=1.12; 95%CI =1.02-1.24, p=0.016 presented a higher prevalence of body image dissatisfaction. The prevalence of body image dissatisfaction is high and the proportion of inadequate anthropometric indicators requires attention. Moreover, body dissatisfaction was more prevalent among overweight women and women with an inadequate conicity index. These results indicate the need for interventions and for the implementation of programs designed to control body weight and to reduce cardiovascular risk factors and body image dissatisfaction in women attending primary health care centers, such as cancer screening services.

    Full Text Available OBJECTIVE: To evaluate the level of satisfaction with body weight and the self-perception of the weight/height ratio and to verify the influence of the frequency of present and past physical activity on these variables. METHODS: Using questionnaires or interviews, we obtained height data, reported and desired weight, self-perception of the weight/height ratio, and the frequency of current physical activity in 844 adults (489 women. Of these, evaluated the frequency of physical activity during high school of 193 individuals,and we measured their height and weight. RESULTS: Less than 2/3 of the individuals had body mass index between 20 and 24.9 kg/m2. A tendency existed to overestimate height by less than 1 cm and to underestimate weight by less than 1kg. Desired weight was less than that reported (p<0.001, and only 20% were satisfied with their current weight. Only 42% of men and 25% of women exercised regularly. No association was found between the frequency of physical activity and the variables height, weight, and body mass index, and the level of satisfaction with current weight. CONCLUSION: Height and weight reported seem to be valid for epidemological studies, and great dissatisfaction with body weight and a distorted self-perception of height/weight ratio exists, especially in women, regardless of the frequency of physical activity.

    Media exposure has been positively correlated with body dissatisfaction. While body image concerns are common, being African American has been found to be a protective factor in the development of body dissatisfaction. Participants either viewed ten advertisements showing 1) ethnically-similar thin models; 2) ethnically-different thin models; 3) ethnically-similar plus-sized models; and 4) ethnically-diverse plus-sized models. Following exposure, body image was measured. African American women had less body dissatisfaction than Caucasian women. Ethnically-similar thin-model conditions did not elicit greater body dissatisfaction scores than ethnically-different thin or plus-sized models nor did the ethnicity of the model impact ratings of body dissatisfaction for women of either race. There were no differences among the African American women exposed to plus-sized versus thin models. Among Caucasian women exposure to plus-sized models resulted in greater body dissatisfaction than exposure to thin models. Results support existing literature that African American women experience less body dissatisfaction than Caucasian women even following exposure to an ethnically-similar thin model. Additionally, women exposed to plus-sized model conditions experienced greater body dissatisfaction than those shown thin models. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Significant progress of nanotechnology, including in particular biomedical and pharmaceutical applications, has resulted in a high number of studies describing the biological effects of nanomaterials. Moreover, a determination of so-called "critical quality attributes", that is specific physicochemical properties of nanomaterials triggering the observed biological response, has been recognised as crucial for the evaluation and design of novel safe and efficacious therapeutics. In the context of in vitro studies, a thorough physicochemical characterisation of nanoparticles (NPs), also in the biological medium, is necessary to allow a correlation with a cellular response. Following this concept, we examined whether the main and frequently reported characteristics of NPs such as size and the agglomeration state can influence the level and the mechanism of NP cellular internalization. We employed fluorescently-labelled 30 and 80 nm silicon dioxide NPs, both in agglomerated and non-agglomerated form. Using flow cytometry, transmission electron microscopy, the inhibitors of endocytosis and gene silencing we determined the most probable routes of cellular uptake for each form of tested silica NPs. We observed differences in cellular uptake depending on the size and the agglomeration state of NPs. Caveolae-mediated endocytosis was implicated particularly in the internalisation of well dispersed silica NPs but with an increase of the agglomeration state of NPs a combination of endocytic pathways with a predominant role of macropinocytosis was noted. We demonstrated that the agglomeration state of NPs is an important factor influencing the level of cell uptake and the mechanism of endocytosis of silica NPs.

    MDCK and Vero cell lines have been used as substrates for influenza virus replication. However, Vero cells produced lower influenza virus titer yield compared to MDCK. Influenza virus needs molecules for internalisation of the virus into the host cell, such as influenza virus receptor and clathrin. Human influenza receptor is usually a membrane protein containing Sia(α2,6) Gal, which is added into the protein in the golgi apparatus by α2,6 sialyltransferase (SIAT1). Light clathrin A (LCA), light clathrin B (LCB) and heavy clathrin (HC) are the main components needed for virus endocytosis. Therefore, it is necessary to compare the expression of SIAT1 and clathrin in Vero and MDCK cells. This study is reporting the expression of SIAT1 and clathrin observed in both cells with respect to the levels of (1) RNA by using RT-PCR, (2) protein by using dot blot analysis and confocal microscope. The results showed that Vero and MDCK cells expressed both SIAT1 and clathrin proteins, and the expression of SIAT1 in MDCK was higher compared to Vero cells. On the other hand, the expressions of LCA, LCB and HC protein in MDCK cells were not significantly different to Vero cells. This result showed that the inability of Vero cells to internalize H1N1 influenza virus was possibly due to the lack of transmembrane protein receptor which contained Sia(α2,6) Gal.

    SDF1α plays an important role in the regeneration of injured tissue after ischemia or stroke by inducing the migration of progenitor cells. In order to study the function of this therapeutically relevant chemokine site-specific protein labelling is of great interest. However, modification of SDF1α is complicated because of its complex tertiary structure. Here, we describe the first site-specific fluorescent modification of SDF1α by EPL. We recombinantly expressed SDF1α (1-49) by intein-mediated protein expression. The C-terminal peptide SDF1α (50-68) was synthesised by SPPS and selectively labelled with carboxyfluorescein at Lys(56). In a cell migration assay, M-[K(56)(CF)]SDF1α showed a clear potency to induce chemotaxis of human T-cell leukaemia cells. Microscopic analysis on HEK293 cells transfected with the CXCR4 revealed specific binding of the fluorescent ligand. Furthermore, receptor-induced internalisation of the ligand could be visualised. These results show that site-specific modification of SDF1α yields in a biologically functional molecule that allows the characterisation of CXCR4 production of cells on a molecular level. © 2010 European Peptide Society and John Wiley & Sons, Ltd.

    Long-term depression (LTD) can be induced at hippocampal CA1 synapses by activation of either NMDA receptors (NMDARs) or group I metabotropic glutamate receptors (mGluRs), using their selective agonists NMDA and (RS)-3,5-dihydroxyphenylglycine (DHPG), respectively. Recent studies revealed that DHPG-LTD is dependent on activation of postsynaptic protein tyrosine phosphatases (PTPs), which transiently dephosphorylate tyrosine residues in AMPA receptors (AMPARs). Here we show that while both endogenous GluR2 and GluR3 AMPAR subunits are tyrosine phosphorylated at basal activity, only GluR2 is dephosphorylated in DHPG-LTD. The tyrosine dephosphorylation of GluR2 does not occur in NMDA-LTD. Conversely, while NMDA-LTD is associated with the dephosphorylation of GluR1-serine-845, DHPG-LTD does not alter the phosphorylation of this site. The increased AMPAR endocytosis in DHPG-LTD is PTP-dependent and involves tyrosine dephosphorylation of cell surface AMPARs. Together, these results indicate that the subunit selective tyrosine dephosphorylation of surface GluR2 regulates AMPAR internalisation in DHPG-LTD but not in NMDA-LTD in the hippocampus.

    This study investigated the photophysical and photobiological properties of a new amphiphilic chlorin photosensitiser, disulfonated tetraphenylchlorin (TPCS(2a)), for photochemical internalisation (PCI). The absorption and fluorescence spectra of TPCS(2a) were examined in a range of solvents together with fluorescence lifetime measurements. The fluorescence lifetime of TPCS(2a) was found to be 8.5 ns in methanol, whereas non-exponential decays were observed in distilled water due to sensitiser dimerisation. The singlet oxygen quantum yield of TPCS(2a) was determined as 0.62 in deuterated methanol by direct observation of singlet oxygen phosphorescence. In a human oral squamous carcinoma (HN5) cell line, intracellular co-localisation of TPCS(2a) and Alexa488-labelled saporin, a macromolecular toxin, was observed corresponding predominantly to a lysosomal distribution. Intracellular fluorescence redistribution of TPCS(2a) and Alexa488-saporin was observed after 405 nm irradiation. Using two-photon confocal microscopy at 840 nm, and fluorescence lifetime imaging (FLIM), the lifetime was measured as 6 ns in HN5 cells. PCI using TPCS(2a) was shown to be very effective, and a synergistic increase in saporin toxicity was achieved in HN5 cells where viability was significantly reduced after light exposure compared to saporin (25 nM) treatment alone. The results demonstrate the favourable photophysical and photobiological properties of TPCS(2a) for PCI, which induces the relocalisation of a macromolecular anti-cancer toxin inside cells and significantly enhances cell death.

    A novel and promising methodology to perform nuclear reactor design is presented in this work. It achieves to balance efficiently safety and economics at the conceptual engineering stage. The key to this integral approach is to take into account safety aspects in a design optimisation process where the design variables are balanced in order to obtain a better figure of merit related with reactor economic performance. Design parameter effects on characteristic or critical safety variables, chosen from reactor behaviour during accidents and from its probabilistic safety assessment -safety performance indicators-, are synthesised on Safety Design Maps. These maps allow one to compare these indicators with limit values, which are determined by design criteria or regulations, and to transfer these restrictions to the design parameters. In this way, reactor dynamic response and other safety aspects are integrated in a global optimisation process, by means of additional rules to the neutronic, thermal-hydraulic and mechanical calculations. This methodology turns out to be promising to balance and optimise reactor and safety system design in an early engineering stage, in order to internalise cost-efficiently safety issues. It also allows one to evaluate the incremental costs of implementing higher safety levels. Furthermore, through this methodology, a simplified design can be obtained, compared to the resultant complexity when these concepts are introduced in a later engineering stage. (author)

    Metabolic adaptations are essential during tumour growth to maintain the high proliferation levels exhibited by cancer cells. In this study, we examined the transformations that occurred in the lipid metabolism in astrocytic tumours, and the possible role of the fuel-sensing enzyme AMPK. Metabolic targets might help design new and effective drugs for cancer. To accomplish this objective, we studied both mice and human astrocytic tumours. We first used a mouse model of astrocytoma driven by oncogenic H-RasV12 and/or with PTEN deletion based on the common constitutive activation of the Raf/MEK/ERK and PI3K/AKT cascades in human astrocytomas. We then confirmed the results in human glioblastoma cell lines and in glioblastoma tissue samples from patients. We show that the high levels of activated AMPK, observed in astrocytic tumours, increase extracellular lipid internalisation and reduce energy expenditure by inhibiting 'de novo' fatty acid (FA) synthesis, which allows tumour cells to obtain building blocks and energy to be able to create new organelles and new cells. Our findings demonstrate that AMPK plays a crucial role in glioblastoma cell growth and suggest that blocking lipoprotein receptors could potentially be used as a plausible therapeutic approach for these and other type of tumours with high levels of AMPK.

    Full Text Available Adolescence is a period that bears a particular risk for the occurrence of difficulties in psychosocial adaptation. This research was aimed at investigating the predictive power of father’s and mother’s rearing styles for the level of internalised (more specifically, anxiety as a trait and externalised problems on the sample of adolescents (212, aged 12 to 18. The following instruments were used in data collection: the Parental Rearing Style Scale, the Strengths and Difficulties Questionnaire (SDQ and the State-Trait Anxiety Inventory (STAI-Y. The obtained results indicate that an emotionally cold father’s style of rearing and the restricting style of rearing of both parents are significant predictors of the level of general anxiety. When it comes to externalisation, it is shown that cold father’s style of rearing is the only significant predictor. The results may contribute to a better understanding of the adaptive capacities of a child and the family in coping with the critical phases in the development of children and youth.

    2006-01-01

    This paper presents a methodical framework, which is the basis for the economic analysis of the mid-term planning of development of the Polish energy system. The description of the partial equilibrium model and its results are demonstrated for different scenarios applied. The model predicts the generation, investment and pricing of mid-term decisions that refer to the Polish electricity and heat markets. The current structure of the Polish energy sector is characterised by interactions between the supply and demand sides of the energy sector. The supply side regards possibilities to deliver fuels from domestic and import sources and their conversion through transformation processes. Public power plants, public CHP plants, industry CHP plants and municipal heat plants represent the main producers of energy in Poland. Demand is characterised by the major energy consumers, i.e. industry and construction, transport, agriculture, trade and services, individual consumers and export. The relationships between the domestic electricity and heat markets are modelled taking into account external costs estimates. The volume and structure of energy production, electricity and heat prices, emissions, external costs and social welfare of different scenarios are presented. Results of the model demonstrate that the internalisation of external costs through the increase in energy prices implies significant improvement in social welfare

    Photochemical internalisation (PCI) is a technique for releasing biologically active macromolecules from endocytic vesicles by light activation of a photosensitiser localised in the same vesicles of targeted cells. This study investigated the PCI of the toxin gelonin as a way of enhancing the effect of photodynamic therapy (PDT) on a human malignant fibrous histiocytoma transplanted into nude mice using the photosensitiser disulphonated aluminium phthalocyanine (AlPcS2a). Pharmacokinetic studies after intraperitoneal administration showed that the serum level of AlPcS2a fitted a biexponential model (half-lives of 1.8 and 26.7 h). The tumour concentration was roughly constant up to 48 h, although fluorescence microscopy showed that the drug location was initially mainly vascular, but became intracellular by 48 h. To compare PDT with PCI, 48 h after intraperitoneal injection of 10 mg kg−1 AlPcS2a, and 6 h after direct intratumour injection of 50 μg gelonin (PCI) or a similar volume of phosphate-buffered saline (PDT controls), tumour-bearing animals were exposed to red light (150 J cm−2). Complete response was observed for more than 100 days in 50% of the PCI tumours but only 10% of the PDT tumours (P<0.01). In tumours examined histologically 4 days after light delivery, the depth of necrosis was 3–4 mm after PDT, but 7 mm after PCI. The deeper effect after PCI demonstrates that the light fluence needed to kill tumour is less than with PDT. We conclude that PCI with gelonin can markedly enhance the effect of PDT on this type of tumour and may have a role clinically as an adjunct to surgery to control localised disease. PMID:15886704

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

    Although research on the antecedents of job dissatisfaction has been developed greatly, we know little about the role of abusive supervision in generating job dissatisfaction. The contingencies under which abusive supervision relates to employees' job dissatisfaction are still unknown. The present study aimed to fill this research gap by empirically exploring the abusive supervision-job dissatisfaction relationship as well as examining the moderating roles of feedback avoidance and critical thinking on this relationship. We tested the hypotheses with data from a sample of 248 employees from a high-tech communications company in northern China and found that: (a) abusive supervision was positively related to job dissatisfaction; (b) the positive relationship was moderated by both employees' feedback avoidance and critical thinking. We conclude by extracting the theoretical as well as practical contributions, along with a discussion of the promising directions for future research.

    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.

    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.

    Monocytes infected with feline infectious peritonitis virus, a coronavirus, express viral proteins in their plasma membranes. Upon binding of antibodies, these proteins are quickly internalised through a new clathrin- and caveolae-independent internalisation pathway. By doing so, the infected monocytes can escape antibody-dependent cell lysis. In the present study, we investigated which kinases and cytoskeletal proteins are of importance during internalisation and subsequent intracellular transport. The experiments showed that myosin light chain kinase (MLCK) and myosin 1 are crucial for the initiation of the internalisation. With co-localisation stainings, it was found that MLCK and myosin 1 co-localise with antigens even before internalisation started. Myosin 6 co-localised with the internalising complexes during passage through the cortical actin, were it might play a role in moving or disintegrating actin filaments, to overcome the actin barrier. One minute after internalisation started, vesicles had passed the cortical actin, co-localised with microtubules and association with myosin 6 was lost. The vesicles were further transported over the microtubules and accumulated at the microtubule organising centre after 10 to 30 min. Intracellular trafficking over microtubules was mediated by MLCK, myosin 1 and a small actin tail. Since inhibiting MLCK with ML-7 was so efficient in blocking the internalisation pathway, this target can be used for the development of a new treatment for FIPV.

    Multidrug resistance (MDR) is the major confounding factor in adjuvant solid tumour chemotherapy. Increasing intracellular amounts of chemotherapeutics to circumvent MDR may be achieved by a novel delivery method, photochemical internalisation (PCI). PCI consists of the co-administration of drug and photosensitiser; upon light activation the latter induces intracellular release of organelle-bound drug. We investigated whether co-administration of hypericin (photosensitiser) with mitoxantrone (MTZ, chemotherapeutic) plus illumination potentiates cytotoxicity in MDR cancer cells. We mapped the extent of intracellular co-localisation of drug/photosensitiser. We determined whether PCI altered drug-excreting efflux pump P-glycoprotein (Pgp) expression or function in MDR cells. Bladder and breast cancer cells and their Pgp-overexpressing MDR subclones (MGHU1, MGHU1/R, MCF-7, MCF-7/R) were given hypericin/MTZ combinations, with/without blue-light illumination. Pilot experiments determined appropriate sublethal doses for each. Viability was determined by the 3-[4,5-dimethylthiazolyl]-2,5-diphenyltetrazolium bromide assay. Intracellular localisation was mapped by confocal microscopy. Pgp expression was detected by immunofluorescence and Pgp function investigated by Rhodamine123 efflux on confocal microscopy. MTZ alone (0.1-0.2 microg ml(-1)) killed up to 89% of drug-sensitive cells; MDR cells exhibited less cytotoxicity (6-28%). Hypericin (0.1-0.2 microM) effects were similar for all cells; light illumination caused none or minimal toxicity. In combination, MTZ /hypericin plus illumination, potentiated MDR cell killing, vs hypericin or MTZ alone. (MGHU1/R: 38.65 and 36.63% increase, Phypericin increased killing by 28.15% (Phypericin was evident before illumination and at serial times post-illumination.

    Dextran-coated poly (n-butyl cyanoacrylate) nanoparticles (PBCA-NPs) were prepared and were evaluated for enhanced delivery of a promising anti-Leishmania drug candidate, hydroxymethylnitrofurazone (NFOH), to phagocytic cells. Currently available chemotherapy for leishmaniasis, such as pentavalent antimonials, presents low safety and efficacy. Furthermore, widespread drug resistance in leishmaniasis is rapidly emerging. To overcome these drawbacks, the use of nanosized delivery systems can reduce systemic drug toxicity and increase the drug concentration in infected macrophages, therefore improving treatment of leishmaniasis. PBCA-NPs containing NFOH (PBCA-NFOH-NPs) were prepared by an anionic emulsion polymerisation method. The z-average and polydispersity index (PDI) were determined by photon correlation spectroscopy, the zeta potential by microelectrophoresis and the entrapment efficiency by HPLC. Cytotoxicity was determined using macrophages from BALB/c mice. Efficacy tests were performed using Leishmania amazonensis promastigotes and amastigotes. The z-average of PBCA-NFOH-NPs was 151.5 ± 61.97 nm, with a PDI of 0.104 ± 0.01, a zeta potential of -10.1 ± 6.49 mV and an entrapment efficiency of 64.47 ± 0.43%. Efficacy in amastigotes revealed IC 50 values of 0.33 µM and 31.2 µM for the nanostructured and free NFOH, respectively (95-fold increase). The cytotoxicity study indicated low toxicity of the PBCA-NFOH-NPs to macrophages. The selectivity index was 370.6, which is 49-fold higher than free NFOH (7.6). Such findings indicated that improved efficacy could be due to NP internalisation following site-specific drug delivery and reactivation of immune protective reactions by the NP components. Thus, PBCA-NFOH-NPs have the potential to significantly improve the treatment of leishmaniasis, with reduced systemic side effects.

    Full Text Available Objective: To identify disordered eating behaviors and body image dissatisfaction, as well as their relationship to body fat (BF, among male athletes in high risk sports for eating disorders. Methods: One hundred and fifty-six male athletes were divided into the following categories: weight-class sports, sports where leanness improves performance, and sports with aesthetic ideals. BF was assessed and three questionnaires were used: the Eating Attitudes Test; the Bulimic Investigatory Test, Edinburgh; the Body Shape Questionnaire. Results: Disordered eating behaviors and body image dissatisfaction were found in 43 (27.6% and 23 athletes (14.7%, respectively, and an association was detected between the two variables (p < 0.001. Athletes with and without disordered eating behaviors did not differ in %BF (11.0±5.2% and 9.8±4.0%, respectively; p = 0.106. However, athletes with body image dissatisfaction had higher %BF than those who were satisfied (12.6±5.9% and 9.7±3.9%, respectively; p = 0.034. There were no differences in BF, frequency of disordered eating behaviors, and body image dissatisfaction between sports categories. Conclusion: Nearly one-quarter of athletes showed disordered eating behaviors, which was associated with body image dissatisfaction. Athletes with higher %BF were more likely to be dissatisfied with body image. There was no difference in eating behavior and body image between athletes from different sports categories.

    Cationic peptides proved fundamental importance as pharmaceutical agents and/or drug carrier moieties functioning in cellular processes. The comparison of the in vitro activity of these peptides is an experimental challenge and a combination of different methods, such as cytotoxicity, internalisation rate, haemolytic and antibacterial effect, is necessary. At the same time, several issues need to be addressed as the assay conditions have a great influence on the measured biological effects and the experimental setup needs to be optimised. Therefore, critical comparison of results from different assays using representative examples of cell penetrating and antimicrobial peptides was performed and optimal test conditions were suggested. Our main goal was to identify carrier peptides for drug delivery systems of antimicrobial drug candidates. Based on the results of internalisation, haemolytic, cytotoxic and antibacterial activity assays, a classification of cationic peptides is advocated. We found eight promising carrier peptides with good penetration ability of which Penetratin, Tat, Buforin and Dhvar4 peptides showed low adverse haemolytic effect. Penetratin, Transportan, Dhvar4 and the hybrid CM15 peptide had the most potent antibacterial activity on Streptococcus pneumoniae (MIC lower than 1.2 μM) and Transportan was effective against Mycobacterium tuberculosis as well. The most selective peptide was the Penetratin, where the effective antimicrobial concentration on pneumococcus was more than 250 times lower than the HC 50 value. Therefore, these peptides and their analogues will be further investigated as drug delivery systems for antimicrobial agents.

    The inflammatory response involves a complex interplay of different cytokines which act in an auto- or paracrine manner to induce the so-called acute phase response. Cytokines are known to crosstalk on multiple levels, for instance by regulating the mRNA stability of targeted cytokines through activation of the p38-MAPK pathway. In our study we discovered a new mechanism that answers the long-standing question how pro-inflammatory cytokines and environmental stress restrict immediate signalling of interleukin (IL)-6-type cytokines. We show that p38, activated by IL-1beta, TNFalpha or environmental stress, impairs IL-6-induced JAK/STAT signalling through phosphorylation of the common cytokine receptor subunit gp130 and its subsequent internalisation and degradation. We identify MK2 as the kinase that phosphorylates serine 782 in the cytoplasmic part of gp130. Consequently, inhibition of p38 or MK2, deletion of MK2 or mutation of crucial amino acids within the MK2 target site or the di-leucine internalisation motif blocks receptor depletion and restores IL-6-dependent STAT activation as well as gene induction. Hence, a novel negative crosstalk mechanism for cytokine signalling is described, where cytokine receptor turnover is regulated in trans by pro-inflammatory cytokines and stress stimuli to coordinate the inflammatory response.

    The aim of this work is to elucidate the mechanisms involved in the morphological adaptation and regulation of macrophages in the presence of internalised materials. This development will accelerate the toxicology assessment of novel nanomaterials and subsequently reduce their environmental and health exposure. For this purpose, we adapted our established in vitro culture system to investigate and measure cell shape changes with and without functionalized carbon nanotubes (CNTs). Two nanomaterials, such as fluorescent polystyrene (PS) beads and functionalized CNTs, were employed to track the material location under confocal microscopy, light microscopy and Transmission Electron Microscopy (TEM). It was found that particles equally spread throughout the entire cytoplasm in spherical macrophage; whereas when macrophages where forced to adhere to the substrate, via fibronectin coating, the accumulation of particles and tubes was limited to the vicinity of the nucleus due to the modified cellular micro architecture. TEM analysis also confirmed these findings and demonstrated that CNTs of about 5 |am laid at the bottom of adherent cells. Therefore, this cell shape analysis and manipulation may result very important for the quantification of internalised novel materials with high aspect ratio like nanotubes, nanorods and nanowires.

    Demographic changes are requiring people to work longer. Labour force participation might be promoted by tackling sources of job dissatisfaction. We aimed to describe the epidemiology of job dissatisfaction in older British workers, to explore which perceptions of work contribute most importantly, and to assess possible impacts on health. Participants aged 50-64 years were recruited from 24 English general practices. At baseline, those currently in work (N=5437) reported on their demographic and employment circumstances, overall job satisfaction, perceptions of their work that might contribute to dissatisfaction, and their general health, mood and well-being. Associations of job dissatisfaction with risk factors and potential health outcomes were assessed cross-sectionally by logistic regression, and the potential contributions of different negative perceptions to overall dissatisfaction were summarised by population attributable fractions (PAFs). Job dissatisfaction was more common among men, below age 60 years, those living in London and the South East, in the more educated and in those working for larger employers. The main contributors to job dissatisfaction among employees were feeling unappreciated and/or lacking a sense of achievement (PAF 55-56%), while in the self-employed, job insecurity was the leading contributor (PAF 79%). Job dissatisfaction was associated with all of the adverse health outcomes examined (ORs of 3-5), as were most of the negative perceptions of work that contributed to overall dissatisfaction. Employment policies aimed at improving job satisfaction in older workers may benefit from focussing particularly on relationships in the workplace, fairness, job security and instilling a sense of achievement.

    2018-01-01

    Full Text Available Background: About 2/3 of the Europeans reside in cities. Thus, we must expand our knowledge on how city characteristics affect health and well-being. Perceptions about cities' resources and functioning might be related with health, as they capture subjective experiences of the residents. We characterized the health status of 74 European cities, using all-cause mortality as indicator, and investigated the association of mortality with residents' dissatisfaction with key domains of urban living.Methods: We considered 74 European cities from 29 countries. Aggregated data on residents' dissatisfaction was obtained from the Flash Eurobarometer, Quality of life in European cities (2004–2015. For each city a global dissatisfaction score and a dissatisfaction score by domain (environment, social, economic, healthcare, and infrastructures/services were calculated. Data on mortality and population was obtained from the Eurostat. Standardized Mortality Ratios, SMR, and 95% Confidence Intervals (95% CI were calculated. The association between dissatisfaction scores and SMR was estimated using Generalized Linear Models.Results: SMR varied markedly (range: 73.2–146.5, being highest in Eastern Europe and lowest in the South and Western European cities. Residents' dissatisfaction levels also varied greatly. We found a significant association between city SMR and residents' dissatisfaction with healthcare (β = 0.334; IC 95% 0.030–0.639 and social environment (β = 0.239; IC 95% 0.015–0.464. No significant association was found with the dissatisfaction scores related with the physical and economic environment and the infrastructures/services.Conclusions: We found a significant association between city levels of mortality and residents' dissatisfaction with certain urban features, suggesting subjective assessments can be also used to comprehend urban health.

    Full Text Available The aim of this study was to compare body image and anthropometric indicators among adolescents living with HIV and healthy adolescents (control group. In addition, we verified the associations of anthropometric indicators, infection/treatment, sexual maturity, and sociodemographic characteristics with body image in adolescents living with HIV. One hundred and eleven adolescents aged 10 to 15 years were divided into those living with HIV (n = 57 and a control group (n = 54. Body image was investigated using an eight-point body silhouette scale. Body weight, height, circumferences, and skinfolds were measured. Body image dissatisfaction was found in 54.4% of the adolescents living with HIV, with 38.6% of them wishing to increase their body size. Conversely, body image dissatisfaction was due to the desire to reduce body size in the control group (40.7%. No difference between the HIV and control groups was found for the anthropometric indicators analyzed. Gender (β = -0.52, age (β = 0.18, body weight (β = 0.07, body mass index (β = -0.19, and upper arm muscle area (β = -0.08 explained 42% of the variation in the body image score of adolescents living with HIV. Thinness is the main reason for body image dissatisfaction in adolescents living with HIV. Almost half the body dissatisfaction of adolescents living with HIV was explained by demographic and anthropometric variables.

    2017-12-01

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

    Physicians' satisfaction/dissatisfaction from their job is an important factor associated with health service that deals with human life. This study was conducted to ascertain overall level and proportion of physicians' satisfaction from their job as well as to identify those components that influenced it. A comprehensive customized questionnaire was used with Section A to assess demographic profile of physicians and Section B to assess satisfaction. Response to each question was devised using Likert scale. Likert scale responses were converted to normal scale so that statistical procedures could be naturally developed. A total of 170 physicians were selected using multistage sampling. Questionnaire was administered on one to one basis to avoid non-response. Precise and contextualized descriptive and inferential statistical procedures were used for analysis. Of the 140 physicians, 103 (74%) were satisfied from their job with average score of 19.15 ± 11.46 while 37 (26%) were dissatisfied with average score -09.27 ± 06.30. Nine out of 15 components were found significant (P<0.05). Comparative assessment of the present results with those of other studies revealed that satisfaction percentage of Indian physicians and those of the developed countries were almost the same. Perhaps, magnitude of satisfaction level (average score) of the Indian physicians were towards the lower side. Nine determinants, identified in this study can be used safely to assess any professionals' satisfaction.

    Full Text Available The family context plays a critical role in the health of the child. This was the first study to examine the usefulness of the General Functioning subscale of the Family Assessment Device (FAD-GF in assessing family functioning and its relationship to internalising symptoms in school-aged children aged between 9 and 11 years of age. Eight hundred and forty-seven Year 4 and 5 students from 13 schools (607 intervention students, and 240 control students participated in the Aussie Optimism Positive Thinking Skills Program (AO-PTS - a universal school-based program targeting internalising symptoms. Students rated how ‘healthy’ they perceived their family to be at pre-test and at 6-month follow-up. Although some aspects of validity and reliability could be improved, results indicated that perceptions of family functioning at pre-test were predictive of internalising symptoms at the 6-month follow-up. The FAD-GF therefore showed promise as a potential measure of family functioning for children as young as nine years old. Regardless of children’s pre-test levels of perceived family functioning, no intervention effects were found on the anxiety and depression scales; this finding suggests that child perceptions of family functioning may act as a general protective factor against internalising symptomology.

    The internalisation potential of Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7 and Salmonella enterica subsp. enterica serovar Typhimurium in lettuce was evaluated using seedlings grown in vermiculite in seedling trays as well as hydroponically grown lettuce. Sterile distilled water was spiked with one of the four human pathogenic bacteria (10(5) CFU/mL) and used to irrigate the plants. The potential for pathogen internalisation was investigated over time using light microscopy, transmission electron microscopy and viable plate counts. Additionally, the identities of the pathogens isolated from internal lettuce plant tissues were confirmed using polymerase chain reaction with pathogen-specific oligonucleotides. Internalisation of each of the human pathogens was evident in both lettuce seedlings and hydroponically grown mature lettuce plants. To our knowledge, this is the first report of S. aureus internalisation in lettuce plants. In addition, the levels of background microflora in the lettuce plants were determined by plate counting and the isolates identified using matrix-assisted laser ionisation-time of flight (MALDI-TOF). Background microflora assessments confirmed the absence of the four pathogens evaluated in this study. A low titre of previously described endophytes and soil inhabitants, i.e., Enterobacter cloacae, Enterococcus faecalis, Lysinibacillus fusiformis, Rhodococcus rhodochrous, Staphylococcus epidermidis and Staphylococcus hominis were identified.

    An indirect approach has been made to study the molecular details associated with the estradiol-induced internalisation of the non-activated estrogen receptor (naER) from the goat uterine plasma membrane. The internalisation of naER appears to be an energy dependent process. Exposure of the plasma membrane to estradiol results in the activation of a Mg2+ dependent ATPase associated with the membrane fraction. Presence of quercetin in the medium prevented the activation of the Mg2+ ATPase as well as the dissociation of naER from the plasma membrane. Using isolated plasma membrane preparations it has been possible to identify the proteins which interact with naER during various stages of its internalisation. The main proteins identified are: (1) a 58 kDa protein, p58, which apparently recognizes the nuclear localization signals on the naER and transports it to the nucleus: (2) hsp70: (3) hsp90, the functional roles of which remain unknown at this stage; (4) a 50 kDa protein associated with the clathrin coated vesicles, presumed to be involved in recognizing the tyrosine based internalisation signals on the naER; (5) actin which mediates the plasma membrane-to-nucleus movement of the naER-p58 complex.

    The fibronectin-binding proteins (FnBPs) PrtF1 and PrtF2 are considered to be major group A streptococcal virulence factors, mediating adherence to and internalisation of host cells. The present study investigated an association between the presence of prtF1 and prtF2 genes and internalisation efficiency in group A streptococci (GAS) isolated from patients with invasive disease. Of the 80 isolates tested, 58 (73%) had prtF1 and 71 (89%) possessed prtF2. Three isolates (4%) had neither gene, seven (9%) had prtF1 only, 19 (24%) had prtF2 only and 51 isolates (64%) had both prtF1 and prtF2. prtF2-positive isolates internalised up to three times more efficiently than isolates that had prtF1 alone (Pinternalisation efficiency and presence of the prtF1 gene. Analysis of the fibronectin-binding repeat domain (FBRD) of prtF2 revealed that this gene can contain 2, 3, 4 or 5 repeat regions and that five repeat regions conferred very high internalisation efficiency in invasive GAS isolates.

    Photochemical internalisation, a novel minimally invasive treatment, has shown promising preclinical results in enhancing and site-directing the effect of anticancer drugs by illumination, which initiates localised chemotherapy release. We assessed the safety and tolerability of a newly developed photosensitiser, disulfonated tetraphenyl chlorin (TPCS2a), in mediating photochemical internalisation of bleomycin in patients with advanced and recurrent solid malignancies. In this phase 1, dose-escalation, first-in-man trial, we recruited patients (aged ≥18 to internalisation were either local, resulting from the local inflammatory process, or systemic, mostly as a result of the skin-photosensitising effect of TPCS2a. The most common grade 3 or worse adverse events were unexpected higher transient pain response (grade 3) localised to the treatment site recorded in nine patients, and respiratory failure (grade 4) noted in two patients. One dose-limiting toxicity was reported in the 1·0 mg/kg cohort (skin photosensitivity [grade 2]). Dose-limiting toxicities were reported in two of three patients at a TPCS2a dose of 1·5 mg/kg (skin photosensitivity [grade 3] and wound infection [grade 3]); thus, the maximum tolerated dose of TPCS2a was 1·0 mg/kg. Administration of TPCS2a was found to be safe and tolerable by all patients. No deaths related to photochemical internalisation treatment occurred. TPCS2a-mediated photochemical internalisation of bleomycin is safe and tolerable. We identified TPCS2a 0·25 mg/kg as the recommended treatment dose for future trials. PCI Biotech.

    2016-08-01

    Burnout is common in professions such as medicine in which employees have frequent and often stressful interpersonal interactions where empathy and emotional control are important. Burnout can lead to decreased effectiveness at work, negative health outcomes, and less job satisfaction. A relationship between burnout and job satisfaction is established for several types of physicians but is less studied among surgeons who treat musculoskeletal conditions. We asked: (1) For surgeons treating musculoskeletal conditions, what risk factors are associated with worse job dissatisfaction? (2) What risk factors are associated with burnout symptoms? Two hundred ten (52% of all active members of the Science of Variation Group [SOVG]) surgeons who treat musculoskeletal conditions (94% orthopaedic surgeons and 6% trauma surgeons; in Europe, general trauma surgeons do most of the fracture surgery) completed the Global Job Satisfaction instrument, Shirom-Malamed Burnout Measure, and provided practice and surgeon characteristics. Most surgeons were male (193 surgeons, 92%) and most were academically employed (186 surgeons, 89%). Factors independently associated with job satisfaction and burnout were identified with multivariable analysis. Greater symptoms of burnout (β, -7.13; standard error [SE], 0.75; 95% CI, -8.60 to -5.66; p job satisfaction. Having children (β, -0.45; SE, 0.0.21; 95% CI, -0.85 to -0.043; p = 0.030; adjusted R(2), 0.046) was the only factor independently associated with fewer symptoms of burnout. Among an active research group of largely academic surgeons treating musculoskeletal conditions, most are satisfied with their job. Efforts to limit burnout and job satisfaction by optimizing engagement in and deriving meaning from the work are effective in other settings and merit attention among surgeons.

    Most patients who receive a total knee arthroplasty (TKA) undergo rehabilitation in the postoperative period. However, these therapies are often not under the direct supervision of the treating physicians, have variable protocols, and have unclear long-term efficacies. The purposes of this study were to assess patient satisfaction with their rehabilitation following TKA and to evaluate whether various factors were different between satisfied and unsatisfied patients. A total of 100 consecutive patients who underwent 107 primary TKA were prospectively surveyed to evaluate their rehabilitation experiences. There were 28 men and 72 women who had a mean age of 61 years (range, 37 to 91 years) at the time of surgery. Patients answered questions regarding the number and duration of therapies, amount of hands-on time with the therapists, number of different therapists, amount of co-pay, and their overall level of satisfaction with their rehabilitation experience. Over one-third of the patients reported not being satisfied with their rehabilitation experiences. The patients who were dissatisfied reported a shorter mean duration of each therapy session spent directly with the therapist, a higher mean number of therapists seen over the duration of their treatment, and an increased number of co-participants during their therapy sessions. The authors believe that to minimize patient dissatisfaction with rehabilitation, surgeons should refer patients to therapists who are willing to spend adequate hands-on time during one-on-one or smaller group therapy sessions with their patients.

    Full Text Available Introduction The prevalence of sexual dysfunction (SD and dissatisfaction with sexual life (DSL in patients with chronic hepatitis C virus infection (CHC was jointly investigated via a thorough psychopathological analysis, which included dimensions such as fatigue, impulsiveness, psychiatric comorbidity, health-related quality of life (HRQL and sociodemographic and clinical characteristics. Methods Male and female CHC patients from an outpatient referral center were assessed using the Brief Fatigue Inventory, the Barrat Impulsiveness Scale, the Beck Depression Inventory (BDI, the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale (HAM-A, and the World Health Organization Quality of Life Scale-Brief Version (WHOQOL-BREF. Structured psychiatric interviews were performed according to the Mini-International Neuropsychiatric Interview. SD was assessed based on specific items in the BDI (item 21 and the HAM-A (item 12. DSL was assessed based on a specific question in the WHOQOL-BREF (item 21. Multivariate analysis was performed according to an ordinal linear regression model in which SD and DSL were considered as outcome variables. Results SD was reported by 60 (57.1% of the patients according to the results of the BDI and by 54 (51.4% of the patients according to the results of the HAM-A. SD was associated with older age, female gender, viral genotype 2 or 3, interferon-α use, impulsiveness, depressive symptoms, antidepressant and benzodiazepine use, and lower HRQL. DSL was reported by 34 (32.4% of the patients and was associated with depressive symptoms, anxiety symptoms, antidepressant use, and lower HRQL. Conclusions The prevalence of SD and DSL in CHC patients was high and was associated with factors, such as depressive symptoms and antidepressant use. Screening and managing these conditions represent significant steps toward improving medical assistance and the HRQL of CHC patients.

    In this study, we focused on measuring levels of nurse burnout and job dissatisfaction in the daily practice of nurses in Hunan province, China, analyzed factors related to nurse burnout and job dissatisfaction, and explored the relationship between them. Previous studies have shown a high level of burnout and job dissatisfaction among nurses worldwide. A cross-sectional survey of 1100 nurses was conducted. The nurses worked at 20 hospitals in 11 cities and counties throughout China's Hunan province. Nurse burnout was measured by the Maslach Burnout Inventory. Nurse-rated job dissatisfaction was described using a four point scale, and work environment was measured using the Nursing Work Index - Practice Environment Scale. The results showed that nurses had high burnout scores and were dissatisfied with their jobs. Staffing, work environment, and work hours were all significantly associated with nurse burnout and job dissatisfaction. Adequate staffing, improved work environment, and reasonable work hours are related to decreasing nurse burnout and job dissatisfaction. © 2015 Wiley Publishing Asia Pty Ltd.

    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.

Body dissatisfaction has been linked to dysfunctional selective visual attention towards one's body. In comparison to

  3. Nuclear industry and the management of accident risk in Europe: from the internalisation default to the coverage organization

    The production of nuclear energy creates environmental and sanitary risks among which the risk of nuclear accident. There is a twofold dimension in the management of such a risk: a preventive dimension and a compensatory one. Given its catastrophic and unpredictable character, the nuclear risk has always been managed in a specific way. In Europe, its management is unsatisfactory. The civil liability regime is beneficial to the nuclear industry as it leads to a lack of internalisation and thus to a limited coverage of potential damages. The financial cap of the nuclear operator's civil liability reduces his incentives for the prevention of accidents. By narrowing its liability, it also limits the burden tied to the coverage of the full potential damages. The organisation of the nuclear risk coverage was heavily conditioned by the civil liability regime and the financial cap it creates. Such an organisation is inefficient. The nuclear insurance market's financial capacity is not enough to compensate for all the potential victims of a major nuclear accident. Moreover, the functioning of this market is quite costly for the nuclear operator. While new electronuclear projects are being launched in Europe, the management of nuclear risks must be questioned in order to find better solutions to the necessity of internalising, preventing and compensating. Nuclear operators should be responsible for all the damages caused through an unlimited liability rule. The coverage of potential damages could also be improved by setting up a risk-sharing agreement at the European scale between operators. (author)

    Although it has been well established that different species of marine algae have different sensitivities to metals, our understanding of the physiological and biochemical basis for these differences is limited. This study investigated copper adsorption and internalisation in three algal species with differing sensitivities to copper. The diatom Phaeodactylum tricornutum was particularly sensitive to copper, with a 72-h IC50 (concentration of copper to inhibit growth rate by 50%) of 8.0 microg Cu L(-1), compared to the green algae Tetraselmis sp. (72-h IC50 47 microg Cu L(-1)) and Dunaliella tertiolecta (72-h IC50 530 microg Cu L(-1)). At these IC50 concentrations, Tetraselmis sp. had much higher intracellular copper (1.97+/-0.01 x 10(-13)g Cu cell(-1)) than P. tricornutum (0.23+/-0.19 x 10(-13)g Cu cell(-1)) and D. tertiolecta (0.59+/-0.05 x 10(-13)g Cu cell(-1)), suggesting that Tetraselmis sp. effectively detoxifies copper within the cell. By contrast, at the same external copper concentration (50 microg L(-1)), D. tertiolecta appears to better exclude copper than Tetraselmis sp. by having a slower copper internalisation rate and lower internal copper concentrations at equivalent extracellular concentrations. The results suggest that the use of internal copper concentrations and net uptake rates alone cannot explain differences in species-sensitivity for different algal species. Model prediction of copper toxicity to marine biota and understanding fundamental differences in species-sensitivity will require, not just an understanding of water quality parameters and copper-cell binding, but also further knowledge of cellular detoxification mechanisms.

    Several studies have demonstrated that culture plays a fundamental role in individuals' beliefs, attitudes, and values toward sexuality, and influences their ability to enjoy sex. It follows that culture may influence sexual satisfaction or dissatisfaction. To examine and compare cognitive-emotional variables related to women's sexual dissatisfaction in Iran and New Zealand. In total, 196 Iranian women and 207 New Zealand women participated in the study, answering questionnaires evaluating dysfunctional sexual beliefs, automatic thoughts, emotional and sexual response during sexual activity, as well as sexual satisfaction. Sexual beliefs were measured by the Sexual Dysfunctional Beliefs Questionnaire, thoughts and emotional responses were measured by the Sexual Modes Questionnaire, and sexual satisfaction was measured by the Sexual Satisfaction Index. Findings indicated that in both Iranian and New Zealand women, failure and disengagement thoughts, lack of erotic thoughts, and emotions of fear during sexual activity were significant predictors of sexual dissatisfaction. Besides these common predictors, results also indicated that sexual conservatism and women's sexual passivity beliefs, sexual abuse thoughts, and fear during sexual activity were significant predictors of sexual dissatisfaction in Iranian women. Beliefs of sexual desire and pleasure as a sin; age-related beliefs; and emotions such as sadness, disillusion, and hurt were significant predictors of sexual dissatisfaction in New Zealand women. The present findings could facilitate a better understanding of cultural differences in the roles played by dysfunctional sexual beliefs, negative automatic thoughts, and negative emotions during sexual activity, and the value of these beliefs, thoughts, and emotions in predicting sexual dissatisfaction. The strength of this study is in providing an examination of the role of culturally bound beliefs in predicting sexual dissatisfaction in women from different

    Full Text Available This study aimed to investigate associations among body dissatisfaction, behaviors, feelings, and beliefs related to the body - and somatotypical profile. The sample included 142 undergraduate female students (21.81 ± 3 years who underwent to assessment of Body Mass Index and somatotype, according to the World Health Organization and Heath-Carter protocols, respectively. To assess body image the following instruments were applied: Body Shape Questionnaire, Body Attitudes Questionnaire, Body Image Avoidance Questionnaire, Sociocultural Attitudes Towards Appearance Scale, Self-Subject Silhouettes To the analysis data we proceeded to multivariate analysis of variance (MANOVA one-way. As the main result, we find that body dissatisfaction, body avoidance and negative attitudes about appearance components are linked to each other and they are influenced by body profiles with mesomorphic and endomorphic predominance. We conclude that the somatotype profile can be an important predictor of changes in body image and is indicated for tracking risk groups.

    2007-06-01

    We explored the extent to which changes in emotional states following exposure to images of idealized bodies predict unhealthy body change attitudes and behaviors in women and men, and whether particular psychological traits mediate these effects. One hundred thirty-three women and 93 men were assessed for unhealthy attitudes and behaviors related to body weight and muscles using the Eating Disorder Inventory-2 (EDI-2), the Obligatory Exercise Questionnaire, and the strategies to increase muscles subscale of the Body Change Inventory. Psychological traits assessed included body dissatisfaction (EDI-2), internalization of the thin/athletic ideal (Sociocultural Attitudes Towards Appearance Questionnaire-3), body comparison (Body Comparison Scale), self-esteem (Rosenberg Self-Esteem Inventory), depression (Beck Depression Inventory-II), and identity confusion (Self-Concept Clarity Scale). Participants were then exposed to photographs of thin female models and muscular male models, and visual analogue scales were used to measure changes in postexposure state body dissatisfaction, anger, anxiety, and depression. Postexposure increases in state anger, anxiety, depression, and body dissatisfaction correlated with drive for thinness and disordered eating symptomatology in women, while postexposure increases in state body dissatisfaction correlated with muscle development in men. Analyses revealed that internalization and body comparison mediated these relationships, with trait body dissatisfaction, trait depression, self-esteem, and self-concept/identity confusion serving as mediators for women only. These results are indicative of gender differences in: (a) reactions to idealized bodies; (b) psychological traits that predispose individuals to experience these reactions; and (c) types of body change behavior that are associated with these reactions.

  11. Qualitative insights into job satisfaction and dissatisfaction with management among community and hospital pharmacists.

    Ferguson, Jane; Ashcroft, Darren; Hassell, Karen

    2011-09-01

    Job satisfaction research in pharmacy has predominantly been investigated using quantitative measures that have generally overlooked satisfaction with management. This article explores pharmacists' experiences and perceptions of management and examines the implications for job satisfaction. Semi-structured interviews were conducted with a convenience sample of 11 community and 15 hospital pharmacists in the North West of England (n=26). The interview schedule was composed of broad questions relating to job satisfaction and dissatisfaction, allowing for the exploration of original themes. Interviews were transcribed verbatim and entered into NVivo8. Template analysis was used to develop a hierarchical list of codes representing themes and the relationships between themes. Dissatisfaction with management emerged as a dominant aspect of pharmacists' job dissatisfaction. Of the 26 pharmacists interviewed, 24 commented on their dissatisfaction with management, whereas only 8 participants commented on positive experiences. Both hospital and community pharmacists expressed dissatisfaction with their line management, and how the organizations they worked for were managed. Findings suggest that satisfaction with management is an important and significant contributor to job satisfaction overall. It would appear that pharmacists' job satisfaction is compromised by poor line management, lack of recognition, and support from management, which may lead to an increase in turnover and a reduction in job satisfaction.

    Although laparoscopic Heller myotomy has been shown to well palliate symptoms of achalasia, we have observed a small subset of patients who are "Dissatisfied". This study was undertaken to identify the causes of their dissatisfaction. Patients undergoing laparoscopic Heller myotomy from 1992 to 2015 were prospectively followed. Using a Likert scale, patients rated their symptom frequency/severity before and after the procedure. Patients graded their experience from "Very Satisfying" to "Very Unsatisfying." 647 patients underwent laparoscopic Heller myotomy. Fifty (8%) patients, median age 57 years and BMI 24 kg/m 2 reported dissatisfaction at follow-up subsequent to myotomy. "Dissatisfied" patients were more likely to have undergone prior abdominal operations (p = 0.01) or previous myotomies (p = 0.02). "Dissatisfied" patients had a greater incidence of diverticulectomy (p = 0.03) and had longer postoperative LOS (p = 0.01). Symptom frequency/severity persisted after myotomy for dissatisfied patients (p > 0.05). Dissatisfaction after laparoscopic Heller myotomy is directly related to persistent/recurrent symptoms. Previous abdominal operations/myotomies, diverticulectomies, and longer LOS are predictors of dissatisfaction. With this understanding, we can identify patients who might be more prone to dissatisfaction. Copyright © 2017 Elsevier Inc. All rights reserved.

    To identify patient and caregiver characteristics associated with caregiver dissatisfaction with hospital care of cognitively impaired elderly adults. Secondary analysis of data from a randomized controlled trial. An 1,800-bed general hospital in England providing the only emergency medical services in its area. Cognitively impaired individuals aged 65 and older randomly assigned to a specialist unit or standard geriatric or internal medical wards (N = 600) and related caregivers (N = 488). Patient and caregiver health status was measured at baseline, including delirium, cognitive impairment, behavioral and psychological symptoms, activities of daily living, and caregiver strain. Caregiver satisfaction with quality of care was ascertained after hospital discharge or death. Four hundred sixty-two caregivers completed satisfaction questionnaires. Regardless of assignment, 54% of caregivers were dissatisfied with some aspects of care, but overall 87% were satisfied with care. The main areas of dissatisfaction were communication, discharge planning, and medical management. Dissatisfaction was associated with high levels of patient behavioral and psychological symptoms on admission, caregiver strain and poor psychological well-being at admission, a diagnosis of delirium, and the relationship between the caregiver and the patient. There was less dissatisfaction from caregivers of patients managed on the specialist Medical and Mental Health Unit than those on standard wards, after controlling for multiple factors. Dissatisfaction was associated with patient behavioral and psychological symptoms and caregiver strain but was not immutable to efforts to improve care. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    2015-08-01

    This study aimed to assess the adoption of sun protection and sun exposure behaviors, the extent to which these behaviors group together, and the relationship between skin tone dissatisfaction and sun-related behaviors in South Australian adolescents (aged 12-17). A total of 2,875 secondary school students (1,461 male and 1,414 female) completed a questionnaire including questions about sun protection and sun exposure behaviors and skin tone dissatisfaction. Regular adoption of sun protection behaviors was low and ranged from 20% (wearing protective clothing) to 44% (sunscreen use). A principal components analysis identified four subgroups of sun-related behaviors: sun protection, appearance enhancement, sun avoidance, and sun exposure. Females had significantly higher skin tone dissatisfaction than males. Skin tone dissatisfaction was associated with decreased sun protection and avoidance and increased appearance enhancement and sun exposure in both males and females. Skin tone dissatisfaction plays an important role in Australian adolescents' sun-related behavior. Appearance-based interventions may be effective in reducing skin cancer risk through reduced sun exposure.

  15. Nurses' job dissatisfaction and turnover intention: methodological myths and an alternative approach.

    2005-09-01

    Job dissatisfaction and turnover are recurring themes in nursing. The current international nursing shortage has resulted in increased interest in investigating the causes of nurses' job dissatisfaction and turnover, and in developing countermeasures to address these issues. This paper involves a review of quantitative nursing studies, which investigated the causes of nurses' job dissatisfaction and turnover intention, and identifies commonly held myths that may inhibit more nurse-centered strategies from being developed. These myths are based on an assumption that a nurse-environment relationship is a one-way interaction in which nurses passively respond to their environment. The paper introduces the person-environment fit theory as an alternative framework, which challenges the assumption by suggesting it is the relationship between person and environment, rather than environmental characteristics alone, that affects nurses' occupational behavior. This theory enables nurse researchers to develop a more mutual approach involving the nurse and environment.

    To explore the relationship between nurse outcomes (dissatisfaction and emotional exhaustion) and nurse workload, nurse characteristics and hospital variables. Concern about the impact of restructuring of nurse staffing, and reports of nurse shortages, on nurse and patient outcomes led to the research being reported on in this article. A questionnaire survey of registered nurses in Scotland and England. A questionnaire survey of the hospitals in which these nurses worked. Respondents in the two countries were similar in terms of demographic, work and employment characteristics. Significant relationships were found using the combined English and Scottish data between nurse patient ratios and (1) emotional exhaustion and (2) dissatisfaction with current job reported by nurses. Increasing numbers of patients to nurses was associated with increasing risk of emotional exhaustion and dissatisfaction with current job.

    To study the relationships between working conditions, job dissatisfaction and smoking behaviors among clerks and manual workers. We used data from the French Health Barometer, a cross-sectional telephone survey conducted among a national random sample (N = 4825). Regarding working conditions, the questionnaire dealt with reported job satisfaction, psychological demands and mental workload, physical demands, latitude decision and work schedule. Manual workers and clerks who reported strong dissatisfaction toward unhealthy working conditions also reported more frequently current smoking, tobacco dependence, potential alcohol dependence and perceived stress. After adjusting for socio-demographic confounders, perceived working conditions and job dissatisfaction remained correlated with smoking and tobacco dependence. Poor working conditions may heavily contribute to health inequalities, as they are likely to fuel both stress and unhealthy behaviors, which combine to increase morbidity and mortality.

    2017-09-01

    This study examined the relationship between work dissatisfaction and sleep problems among Canadian adults in the latter half of life, as well as how gender and social contact moderate this relationship. Data were obtained from the Canadian General Social Survey, Cycle 21 (2007), which sampled adults aged 45 and older in 2007. Analyses focused on individuals with employment as their main activity. Analyses show that work dissatisfaction positively predicts trouble sleeping. There are no significant gender differences in this relationship. Social contact with friends buffers this relationship, but social contact with family does not, and buffering does not vary significantly between men and women. This research contributes to knowledge on sleep problems by showing that work dissatisfaction is adversely associated with sleep problems among Canadians in the latter half of life, but social contact with friends can weaken this deleterious relationship.

    As in many countries, medical and surgical specialists in New Zealand have the opportunity of working in the public sector, the private sector or both. This study aimed to explore the level and sources of satisfaction and dissatisfaction of specialists in New Zealand with working in the two sectors. Such information can assist workforce planning, management and policy and may inform the wider debate about the relationship between the two sectors. A postal survey was conducted of 1983 registered specialists throughout New Zealand. Respondents were asked to assess 14 sources of satisfaction and 9 sources of dissatisfaction according to a 5-point Likert scale. Means and standard deviations were calculated for the total sample, and for procedural and non-procedural specialties. Differences between the means of each source of satisfaction and dissatisfaction were also calculated. Completed surveys were received from 943 specialists (47% response rate). Overall mean levels of satisfaction were higher in the private sector than the public sector while levels of dissatisfaction were lower. While the public system is valued for its opportunities for further education and professional development, key sources of dissatisfaction are workload pressures, mentally demanding work and managerial interference. In the private sector specialists value the opportunity to work independently and apply their own ideas in the workplace. Sources of job satisfaction and dissatisfaction amongst specialists are different for the public and private sectors. Allowing specialists more freedom to work independently and to apply their own ideas in the workplace may enhance recruitment and retention of specialists in the public health system.

    Secondary pneumonia caused by Staphylococcus aureus is reemerging as a primary cause of excess mortality associated with infection by the influenza A virus. We have investigated in vitro the cellular and molecular mechanisms underlying this synergism. Experimental data show a significant increase in the efficiency of internalisation of S. aureus into cultured pneumocytes during the early phases of viral infection, while a relevant increase in the efficiency of adhesion is evident only later during viral infection, suggesting that the 2 effects are based on different molecular mechanisms. Data reported in this paper show that S. aureus cells can bind the viral hemagglutinin (HA) and that this binding promotes enhanced bacterial internalisation by 2 mechanisms: binding to HA exposed at the surface of infected cells and binding to free extracellular virions, enabling internalisation at high efficiency also in cells that are not infected by the virus. The affinity of binding that involves S. aureus and HA was shown to be enhanced by the reducing extracellular environment that the virus can generate. Copyright © 2010 Elsevier GmbH.

    2008-07-01

    The LOX-1 scavenger receptor recognises pro-atherogenic oxidised low-density lipoprotein (OxLDL) particles and is implicated in atherosclerotic plaque formation, but this mechanism is not well understood. Here we show evidence for a novel clathrin-independent and cytosolic-signal-dependent pathway that regulates LOX-1-mediated OxLDL internalisation. Cell surface labelling in the absence or presence of OxLDL ligand showed that LOX-1 is constitutively internalised from the plasma membrane and its half-life is not altered upon ligand binding and trafficking. We show that LOX-1-mediated OxLDL uptake is disrupted by overexpression of dominant-negative dynamin-2 but unaffected by CHC17 or mu2 (AP2) depletion. Site-directed mutagenesis revealed a conserved and novel cytoplasmic tripeptide motif (DDL) that regulates LOX-1-mediated endocytosis of OxLDL. Taken together, these findings indicate that LOX-1 is internalised by a clathrin-independent and dynamin-2-dependent pathway and is thus likely to mediate OxLDL trafficking in vascular tissues.

  3. Impact of a possible environmental externalities internalisation on energy prices: The case of the greenhouse gases from the Greek electricity sector

    International Nuclear Information System (INIS)

    Georgakellos, Dimitrios A.

    2010-01-01

    The present paper is concerned with the impact of the internalisation of environmental externalities on energy prices. In this context, its aim is to quantify the external cost of greenhouse gases (specifically carbon dioxide) generated during electricity production in the thermal power plants in Greece and to estimate the impact on the electricity production cost and on the electricity prices of a possible internalisation of this external cost by the producers. For this purpose, this paper applies the EcoSenseLE online tool to quantify the examined externalities. This research finds that the calculated external cost is significantly high (compared to the corresponding production cost) mainly in lignite-fired power plants. Specifically, a possible internalisation of this external cost would increase the production cost by more than 52% (on average), which, in turn, would affect similarly the electricity prices. This finding could be important for decision makers in the electricity sector to develop strategies for emission reduction and to develop environmental and energy policies. The general limitation of the external cost methodology applies to this work as it uses the standard method developed for the Externe project. Similarly, the data limitations as well as assumptions related to the costs and exclusions/ omissions of cost elements affect the results.

    Although trastuzumab, a recombinant humanised anti-ErbB2 antibody, is widely used in the treatment of breast cancer, neither its mechanism of action, nor the factors leading to resistance are fully understood. We have previously shown that antibody-dependent cellular cytotoxicity is pivotal in the in vivo effect of trastuzumab against JIMT-1, a cell line showing in vitro resistance to the antibody, and suggested that masking of the trastuzumab-binding epitope by MUC-4, a cell surface mucin, took place. Here, we further explored the role of masking of ErbB2 in connection with CD44 expression and synthesis of its ligand, hyaluronan. We show that high expression of CD44 observed in JIMT-1 cells correlates with ErbB2 downregulation in vivo, while siRNA-mediated inhibition of CD44 expression leads to decreased rate of trastuzumab internalisation and low cell proliferation in vitro. An inhibitor of hyaluronan synthesis, 4-methylumbelliferon (4-MU) significantly reduced the hyaluronan level of JIMT-1 cells both in vivo and in vitro leading to enhanced binding of trastuzumab to ErbB2 and increased ErbB2 down-regulation. Furthermore, the inhibitory effect of trastuzumab on the growth of JIMT-1 xenografts was significantly increased by 4-MU treatment. Our results point to the importance of the CD44-hyaluronan pathway in the escape of tumour cells from receptor-oriented therapy.

    Regulator of calcineurin 1 (RCAN1) is an endogenous inhibitor of the calcineurin pathway in cells. It is expressed as two isoforms in vertebrates: RCAN1.1 is constitutively expressed in most tissues, whereas transcription of RCAN1.4 is induced by several stimuli that activate the calcineurin-NFAT pathway. RCAN1.4 is highly upregulated in response to VEGF in human endothelial cells in contrast to RCAN1.1 and is essential for efficient endothelial cell migration and tubular morphogenesis. Here, we show that RCAN1.4 has a role in the regulation of agonist-stimulated VEGFR-2 internalisation and establishment of endothelial cell polarity. siRNA-mediated gene silencing revealed that RCAN1 plays a vital role in regulating VEGF-mediated cytoskeletal reorganisation and directed cell migration and sprouting angiogenesis. Adenoviral-mediated overexpression of RCAN1.4 resulted in increased endothelial cell migration. Antisense-mediated morpholino silencing of the zebrafish RCAN1.4 orthologue revealed a disrupted vascular development further confirming a role for the RCAN1.4 isoform in regulating vascular endothelial cell physiology. Our data suggest that RCAN1.4 plays a novel role in regulating endothelial cell migration by establishing endothelial cell polarity in response to VEGF.

    Photochemical internalisation (PCI) is a delivery technology that employs a sub-lethal form of photodynamic therapy (PDT) in which a photosensitiser is activated by light to break down intracellular membranes and release macromolecules into the cytosol where they can be biologically active. Although PCI does enhance the PDT killing of transplanted tumours in mice after local injection of the cytotoxic agent, gelonin, the redistribution of gelonin from intracellular organelles into the cytosol has only previously been demonstrated in vitro. This study is designed to understand the factors controlling the efficacy of PCI in vivo and to document the mechanism of action. Using the photosensitiser AlS(2)Pc in studies on normal rat liver, we have demonstrated in vivo that gelonin is initially taken up into lysosomes, but can be released into the cytosol using PCI. Furthermore, PCI enhances the PDT effect after systemic administration of gelonin (volume of necrosis increased x2.5 when gelonin is given one hour before light), with the remarkably low dose of 5 microg/kg (10,000 times lower than the LD50); in the absence of light, there is no effect with 500 microg/kg. These results suggest that PCI may have a useful role to play in the site specific activation of cytotoxic agents like gelonin, given at a dose level that has no effect in the absence of light.

  11. The Potentiality of a Healthy Self: Evaluating Progressively Empowered Internalisation and Diagnosis through the Lens of Existential Epistemology.

    Science.gov (United States)

    Westin, Anna

    2016-11-01

    In this article I will examine how the language of diagnosis can engage with existential epistemology to develop a concept of Progressively Empowered Internalisation (PEI). This, I will argue, challenges conceptualisations of diagnosis as articulating and maintaining a static self-concept. It enables the individual to synthesise the language of a particular mental experience within the wider engagement of their own active process of self-becoming. I will suggest that this construction of PEI addresses the limitations of stigmatisation and static self-concepts. In seeing the language of diagnosis as a helpful tool for understanding a part of one's self-experience, it presents an alternative to the illness-based model of mental health. This conceptualisation engages with Kierkegaard's existential epistemology, as a means of using language to understand the task of becoming oneself and relating to others. Furthermore, it explores how mental health diagnosis requires communal engagement to enable the wellbeing of its members. Diagnosis is thereby seen as a process of further empowering the individual with the language to explain a particular part of their experience within the overall movement of developing an integrated self-concept.

    Research demonstrates that people living with serious mental illness (SMI) contend with widespread public stigma; however, little is known about the specific experiences of stigma that mothers, and in particular fathers, with SMI encounter as parents. This study aimed to explore and compare the experiences of stigma for mothers and fathers with SMI inferred not only by living with a mental illness but also potential compounding gender effects, and the associated impact of stigma on parenting. Telephone surveys were conducted with 93 participants with SMI who previously identified as parents in the Second Australian National Survey of Psychosis. Results indicated that mothers were more likely than fathers to perceive and internalise stigma associated with their mental illness. Conversely, fathers were more inclined to perceive stigma relating to their gender and to hold stigmatising attitudes towards others. Mental illness and gender stigma predicted poorer self-reported parenting experiences for both mothers and fathers. These findings may assist in tailoring interventions for mothers and fathers with SMI. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Job dissatisfaction and need for recovery are associated with voluntary turnover, absenteeism and diminished health. In the light of encouraging working longer, this study investigated whether the relationships between various work characteristics and job dissatisfaction and need for recovery are dependent on age. Cross-sectional questionnaire data from 591 university employees were divided into four age groups: job dissatisfaction and Task variety with need for recovery were influenced by age group. The salience of specific work characteristics within the age groups varied: for job dissatisfaction, Task variety ( job dissatisfaction and need for recovery in four age groups. Although the moderating effect of age group was rather limited, the salience of specific work characteristics within the age groups varied.

    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.

    Full Text Available 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.

    This study estimates whether physicians in rural Pennsylvania have higher odds of career dissatisfaction and plans to leave patient care in the next 6 years, compared to their urban counterparts. Rural-urban differences were estimated across specific subgroups of physicians (gender, race, and specialty) and with regard to specific sources of career dissatisfaction. The 2012 Pennsylvania Health Workforce Survey of Physicians allowed for analysis of 17,444 physicians younger than 55 years old actively practicing patient care. Multivariate, logistic regression was performed to estimate the associations with 2 outcome areas: career dissatisfaction and plans to leave patient care in the next 6 years. Controls included rural setting, age, sex, race, work hours, specialty, and practice characteristics. Over 12% of under-55 physicians are dissatisfied with their careers and over 18% report plans to leave patient care in the next 6 years. Rural physicians in Pennsylvania have 18.6% higher odds of reporting career dissatisfaction and 29.5% higher odds of leaving patient care in the next 6 years (P work (i.e., stress, practice demands, and lack of autonomy) and family situations and less related to income concerns. © 2015 National Rural Health Association.

    Full Text Available ADHD children can experience severe relational problems with peers, and individual treatments are not likely to eradicate peer problems. The school is the main arena in which peer difficulties develop and can be faced.Present study is aimed to explore the hypothesis that even in a fully inclusive educational system, like the Italian one, ADHD children would still experience peer difficulties if compared with children with other special needs, given the relational implications of the disturb. 31 ADHD children, 31 children with other special needs, 31 children with no special needs, matched by gender and age, were recruited from primary and low secondary State mainstream schools. The "Children's Loneliness and Social Dissatisfaction Rating Scale was administered to all children during class time. A single ANOVA test between the three groups and three planned comparisons were performed on the perceived loneliness and social dissatisfaction scores. The results showed low levels of perceived loneliness and social dissatisfaction for all groups. However, 30% of ADHD children showed a perceived loneliness and social dissatisfaction level twice than the other children, confirming the hypothesis that children with ADHD are at risk of isolation even within a fully inclusive environment.The authors interpretated the results according to a relational perspective, in which ADHD symptoms are not seen as totally dependant on the disorder in itself, but also a specific result of the relational system in which the child is part of. Implications regarding educational strategies and intervention strategies are discussed.

    Jingree, Treena; Finlay, W M L

    2013-06-01

    This paper uses critical discursive psychology to examine expressions of dissatisfaction and complaint by people with learning disabilities. UK government policies stress that people with learning disabilities should have more control over their lives. Expressing dissatisfaction about services is an important aspect of this process. However, given that such individuals are often treated as incompetent, and given the delicate nature of complaining about services one might rely on for day-to-day support, this can be difficult to do. In building complaints, speakers drew on repertoires about competence and incompetence, the right to free choice as a principle, and tempered dissatisfaction to make contrasts between good and bad supporters and practice. While the complaints show many of the general features of complaints identified in previous work in the general population, they were crafted to the particular institutional context of social care, and attended both explicitly and implicitly to the particular issues of competence, power, and authority found in those services. Speakers positioned themselves as competent, and service workers as more or less competent in their roles. Issues of power in social care services were observed explicitly in the accounts, whereby people described staff as controlling and it being difficult to voice dissatisfaction. They were also implicit in the way speakers drew on the others with institutional authority for corroboration and comparison. © 2011 The British Psychological Society.

    To review the existing literature on body image in adolescent pregnancy and explore concepts about the relationship between the two. A systematic review. Peer-reviewed articles were identified through MEDLINE (1946-present) and PsycINFO (1806-November 2013), conducted in any setting. Pregnant and postpartum adolescents ages 13-19 y. None. The outcome measures used in the studies reviewed varied: themes from focus groups, diary entry analysis, Pregnancy and weight gain attitude scale, Edinburgh postnatal depression scale, Parenting stress index, Eating disorder inventory, Tennessee self concept scale. The search yielded a total of 149 studies, of which 6 were relevant to the specific topic and age group. The very limited research shows a dichotomy in body image perception during pregnancy in adolescence; some studies show an increase in body image disturbance and dissatisfaction during pregnancy in adolescents, and other studies reviewed found that the majority of pregnant adolescents had positive body image and positive attitudes towards weight gain. A bidirectional link between depression and negative body image in adolescent pregnancy is suggested. The current research exploring the relationshp between body image and pregnancy in adolescence is limited, both in quality and quantity. Future research is needed to evaluate longitudinal models that will better inform about potential risk factors for body dissatisfaction during pregnancy in adolescence, including the possible role of depression.

    2016-12-01

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

    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

    Previous research indicates that nurses' job dissatisfaction relates to their work organization and environment; rarely has the contribution of employer provided support services been examined while controlling for the influence of other factors. The objective of this study was to examine job dissatisfaction among Canadian registered nurses in relation to employer-provided programs for child care and fitness or recreation. Data are from 2,993 respondents to the 2005 National Survey of the Work and Health of Nurses, weighted to represent Canada's 91,600 registered nurses in full-time, permanent positions who deliver direct care in hospitals or long-term care facilities. Multivariate modeling was used to examine job dissatisfaction in relation to employer-provided support programs, controlling for personal characteristics and variables reflecting work organization and the work environment. Employer-provided child care assistance programs were available to 16% of nurses, and fitness or recreation programs were available to 38%. An estimated 13% of nurses were dissatisfied with their jobs. Even when controlling for personal characteristics, overtime, shift work, shift length, weekly hours, overload, staffing inadequacy, autonomy, nurse-physician relations, and coworker respect, inverse associations with job dissatisfaction emerged for employer-supported child care (odds ratio = 0.49, 95% confidence interval = 0.27-0.88) and fitness programs (odds ratio = 0.65, 95% confidence interval = 0.42-0.99). This study provides new information suggesting that employer-provided support programs are protective against nurses' job dissatisfaction. This is a key finding in view of nursing shortages and the importance of job satisfaction to retention.

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.

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

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

    Despite progress in radio-, chemo- and photodynamic-therapy (PDT) of cancer, treatment resistance still remains a major problem for patients with aggressive tumours. Cancer stem cells (CSCs) or tumour-initiating cells are intrinsically and notoriously resistant to conventional cancer therapies and are proposed to be responsible for the recurrence of tumours after therapy. According to the CSC hypothesis, it is imperative to develop novel anticancer agents or therapeutic strategies that take into account the biology and role of CSCs. The present review outlines our recent study on photochemical internalisation (PCI) using the clinically relevant photosensitiser TPCS2a/Amphinex® as a rational, non-invasive strategy for the light-controlled endosomal escape of CSC-targeting drugs. PCI is an intracellular drug delivery method based on light-induced ROS-generation and a subsequent membrane-disruption of endocytic vesicles, leading to cytosolic release of the entrapped drugs of interest. In different proof-of-concept studies we have demonstrated that PCI of CSC-directed immunotoxins targeting CD133, CD44, CSPG4 and EpCAM is a highly specific and effective strategy for killing cancer cells and CSCs. CSCs overexpressing CD133 are PDT-resistant; however, this is circumvented by PCI of CD133-targeting immunotoxins. In view of the fact that TPCS2a is not a substrate of the efflux pumps ABCG2 and P-glycoprotein (ABCB1), the PCI-method is a promising anti-CSC therapeutic strategy. Due to a laser-controlled exposure, PCI of CSC-targeting drugs will be confined exclusively to the tumour tissue, suggesting that this drug delivery method has the potential to spare distant normal stem cells.
