Variation of anthropometric traits in normal newborns]

Variation of the set of anthropometric traits was studied in 302 normal singleton newborns (174 boys, 128 girls). Birth order has a significant effect on birth weight, body length and circumference of head and breast. The number of minor deviations from development per newborn (stigma) is negatively correlated with body weight and size. The number of stigma is significantly higher in a group of newborns deviated in normal body proportions. The index of fluctuating asymmetry is negatively correlated with body weight and size.     

The estimation of body mass index and physical attractiveness is dependent on the observer's own body mass index

A disturbance in the evaluation of personal body mass and shape is a key feature of both anorexia and bulimia nervosa. However, it is uncertain whether overestimation is a causal factor in the development of these eating disorders or is merely a secondary effect of having a low body mass. Moreover, does this overestimation extend to the perception of other people''s bodies? Since body mass is an important factor in the perception of physical attractiveness, we wanted to determine whether this putative overestimation of self body mass extended to include the perceived attractiveness of others. We asked 204 female observers (31 anorexic, 30 bulimic and 143 control) to estimate the body mass and rate the attractiveness of a set of 25 photographic images showing people of varying body mass index (BMI). BMI is a measure of weight scaled for height (kg m(- 2)). The observers also estimated their own BMI. Anorexic and bulimic observers systematically overestimated the body mass of both their own and other people''s bodies, relative to controls, and they rated a significantly lower body mass to be optimally attractive. When the degree of overestimation is plotted against the BMI of the observer there is a strong correlation. Taken across all our observers, as the BMI of the observer declines, the overestimation of body mass increases. One possible explanation for this result is that the overestimation is a secondary effect caused by weight loss. Moreover, if the degree of body mass overestimation is taken into account, then there are no significant differences in the perceptions of attractiveness between anorexic and bulimic observers and control observers. Our results suggest a significant perceptual overestimation of BMI that is based on the observer''s own BMI and not correlated with cognitive factors, and suggests that this overestimation in eating-disordered patients must be addressed directly in treatment regimes.     

Implicit and Explicit Anti-Fat Bias among a Large Sample of Medical Doctors by BMI,Race/Ethnicity and Gender

Overweight patients report weight discrimination in health care settings and subsequent avoidance of routine preventive health care. The purpose of this study was to examine implicit and explicit attitudes about weight among a large group of medical doctors (MDs) to determine the pervasiveness of negative attitudes about weight among MDs. Test-takers voluntarily accessed a public Web site, known as Project Implicit®, and opted to complete the Weight Implicit Association Test (IAT) (N = 359,261). A sub-sample identified their highest level of education as MD (N = 2,284). Among the MDs, 55% were female, 78% reported their race as white, and 62% had a normal range BMI. This large sample of test-takers showed strong implicit anti-fat bias (Cohen’s d = 1.0). MDs, on average, also showed strong implicit anti-fat bias (Cohen’s d = 0.93). All test-takers and the MD sub-sample reported a strong preference for thin people rather than fat people or a strong explicit anti-fat bias. We conclude that strong implicit and explicit anti-fat bias is as pervasive among MDs as it is among the general public. An important area for future research is to investigate the association between providers’ implicit and explicit attitudes about weight, patient reports of weight discrimination in health care, and quality of care delivered to overweight patients.     

Prevalence,Characteristics, and Correlates of Teasing Experiences among Overweight Children vs. Non‐overweight Peers

Objective: Information regarding the prevalence, nature, sources, and psychosocial correlates of teasing was obtained for overweight (OV) children (10 to 14 years of age) vs. non‐overweight (non‐OV) peers. It was hypothesized that weight‐related teasing would be negatively correlated with self‐esteem in specific domains and with enjoyment of physical/social activities and positively correlated with loneliness, bulimic behaviors, body dissatisfaction, and enjoyment of sedentary/isolative activities. Research Methods and Procedures: Teasing experiences and psychosocial correlates were assessed among OV children from a fitness camp and a demographically similar school sample of non‐OV children. Results: Among the OV children, appearance‐related teasing was more prevalent, frequent, and upsetting, involved disparaging nicknames focusing more on weight rather than less stigmatized aspects of appearance, and more often perpetrated by peers in general rather than a specific peer. Degree of teasing within the full sample was significantly associated with higher weight concerns, more loneliness, poorer self‐perception of one's physical appearance, higher preference for sedentary/isolative activities, and lower preference for active/social activities, all but the latter association holding up above and beyond actual weight status and demographics. Among OV children, teasing was associated with bulimic behaviors. Associations with type of teasing showed specificity, with weight‐related teasing predicting weight and appearance variables and competency‐related teasing related to social domain factors. Discussion: When frequency, intensity, emotional impact, and stigmatized content are examined, findings indicate that teasing is more severe for OV children. Effective interventions are needed to help victims cope with and prevent further weight‐related teasing, which may improve peer functioning, enhance weight control efforts, and reduce risk for future eating disturbance.     

Effects of Reading Health and Appearance Exercise Magazine Articles on Perceptions of Attractiveness and Reasons for Exercise

Objective

To examine the effects of reading exercise-related magazine articles (health, appearance, or control) and the moderating effects of exercise self-identity on reasons for exercise and perceptions of attractiveness, among women in first year university. An additional purpose was to use a thought listing technique, the results of which were examined for evidence of internalization of the exercise-related messages.

Participants

Female students in their first year of studies between September 2010 and April 2011 (N = 173; mean age = 19.31 years, mean body mass index = 22.01).

Methods

Participants read a health, appearance, or control article, listed thoughts, and completed questionnaires measuring reasons for exercising, physical self-perception, and exercise self-identity.

Results

Participants in the health condition rated exercise for health significantly higher than control condition participants. Participants with high exercise self-identity rated attractiveness as a reason for exercising significantly higher than low exercise self-identity participants in both the health and appearance conditions. Participants with higher internalization scores (i.e., accepted societal norms of appearance) reported exercising for attractiveness reasons more so than participants with lower internalization scores.

Conclusions

The good news is that health messages may be influential and result in wanting to exercise for health purposes. However, exercising for attractiveness was rated highly by participants with high exercise identity who read either the health or appearance articles. Health and appearance are not necessarily distinct concepts for female undergraduate students and the media may influence cited reasons for exercise.     

Internalization of weight bias: Implications for binge eating and emotional well-being

Objective: This study examined the relationship between internalization of negative weight‐based stereotypes and indices of eating behaviors and emotional well‐being in a sample of overweight and obese women. Research Method and Procedures: The sample was comprised of 1013 women who belonged to a national, non‐profit weight loss organization. Participants completed an on‐line battery of self‐report questionnaires measuring frequency of weight stigmatization and coping responses to deal with bias and symptoms of depression and self‐esteem, attitudes about weight and obesity, and binge eating behaviors. In addition, participants were asked to list the most common weight‐based stereotypes and whether they believed them to be true or false. Results: Participants who believed that weight‐based stereotypes were true reported more frequent binge eating and refusal to diet in response to stigma experiences compared with those who reported stereotypes to be false. The degree to which participants believed stereotypes to be true or false was not related to types or amount of stigma experiences reported, self‐esteem, depression, or attitudes toward obese persons. In addition, engaging in weight loss strategies as a response to bias was not predicted by stereotype beliefs or by actual stigma experiences, regardless of the amount or types of stigma reported. Discussion: These findings suggest that obese individuals who internalize negative weight‐based stereotypes may be particularly vulnerable to the negative impact of stigma on eating behaviors and also challenge the notion that stigma may motivate obese individuals to engage in efforts to lose weight. This study highlights a new area of research that warrants attention to better understand weight stigma and its potential consequences for health.     

Male facial attractiveness,perceived personality,and child-directed speech

This study investigated associations between men's facial attractiveness, perceived personality, attitudes towards children, and the quality of their child-directed (CD) speech. Sixty-three males were photographed and completed a brief questionnaire concerning their family background and attitudes towards children. They then performed a task in which they gave directions to (imaginary) adults and children. Analyses of the acoustic properties of speech produced under each condition were performed in order to determine the extent to which individual men changed their speech to accommodate a child listener (i.e., exhibited CD speech). The men's faces were rated by 59 female participants, who assessed perceived prosociality, masculinity, health, and short- and long-term attractiveness. Although women's ratings of attractiveness and prosociality were related to men's self-reported liking for children, they were negatively correlated to men's use of CD speech (i.e., less attractive men used more features of CD speech when addressing an imaginary child). These findings are discussed in the context of halo effects and strategic pluralism in male mating behaviors.     

Binge eating and weight loss in a self-help behavior modification program

Objective: To examine the occurrence of binge eating and its impact on weight loss outcomes among obese participants in the Trevose Behavior Modification Program, a lay‐administered, lay‐directed self‐help weight loss program offering continuing care. Research Methods and Procedures: Participants completed questionnaires, and weight loss data were recorded prospectively. Results: Although objective bulimic episodes were reported by 41% of the sample, objective bulimic episodes were not associated with worse weight loss outcomes. Mean weight loss after 12 months was 18.2 kg (18.8% of initial body weight) for the treatment completers and 10.3 kg (10.5% of initial body weight) for the full sample (using intent‐to‐treat analyses, with baseline scores carried forward). Discussion: Substantial long‐term weight loss, resulting from a continuing care treatment program, occurred in individuals both with and without frequent binge eating.     

Gender Differences in Body Satisfaction

PINGITORE, REGINA, BONNIE SPRING, DAVID GARFIELD. Gender differences in body satisfaction. Although men and women show similar rates of obesity, women more frequently engage in weight loss efforts, with potentially adverse health consequences. We surveyed 320 college-aged men and women to examine gender differences in the determinants of body dissatisfaction and the degree of importance assigned to body-weight and shape. Results indicated that, for both genders, satisfaction with bodyweight and shape decreased as body mass index (BMI) increased. Women, however, showed significantly greater body and weight dissatisfaction than men at most weight categories. Only the underweight (BMI<20) women and men were similarly satisfied with their bodyweight and shape. As BMI increased, however, women became disproportionately more dissatisfied: both normal-weight and overweight women expressed greater dissatisfaction than comparable men. College-aged women also attributed progressively more importance to both weight and shape as BMI increased, unlike college-aged men, who considered body weight equally important to (or slightly less important than) self-esteem as BMI increased. We discuss implications for the self-esteem of obese women and men.     

The Social Self,Body Dissatisfaction,and Binge Eating in Obese Females

We examined the relationship of the social self to body dissatisfaction and to binge eating in two clinical samples of obese females. In the first study, with 32 nonbingeing obese females, social self measures of Public Self-Consciousness and Social Anxiety were positively correlated with body dissatisfaction. Self-esteem was negatively correlated with body dissatisfaction. In the second study, 11 obese binge eaters were compared with 11 matched nonbingeing obese females. Binge eaters were characterized by significantly higher levels of social anxiety and body dissatisfaction than the obese nonbingeing controls. These findings support the hypothesized links of social self concerns to body dissatisfaction and to binge eating in obese females .     

Facial sexual dimorphism,developmental stability,and susceptibility to disease in men and women

We investigated aspects of self-reported health history–the number and duration of respiratory and stomach or intestinal infections and the number of uses of antibiotics over the last 3 years–in relation to measured facial masculinity, developmental instability [facial asymmetry and body fluctuating asymmetry (FA)] and facial attractiveness in a sample of 203 men and 203 women. As predicted from the hypothesis that the degree of facial masculinity is an honest signal of individual quality, men's facial masculinity correlated negatively and women's positively with respiratory disease number and duration. Stomach illness, however, was not associated significantly with facial masculinity and antibiotic use correlated significantly (negatively) only with men's facial masculinity. For both facial asymmetry and body FA, significant, positive associations were seen with the number of respiratory infections. In addition, facial asymmetry was associated positively with the number of days infected and marginally, in the same direction, with antibiotic use. Facial attractiveness showed no significant relationships with any of our health-history measures. This study provides some evidence that facial masculinity in both sexes may signal disease resistance and that developmental stability covaries positively with disease resistance. The validity of our health measures is discussed.     

Changes in Eating Attitudes,Body Esteem and Weight Control Behaviours during Adolescence in a South African Cohort

Failure to consume an adequate diet or over consumption during adolescence can disrupt normal growth and development, resulting in undesirable weight change. This leads to an increase in unhealthy weight control practices related to eating and exercise among both adolescent girls and boys to meet the societal ‘ideal’ body shape. This study therefore aims to examine the longitudinal changes in eating attitudes, body-esteem and weight control behaviours among adolescents between 13 and 17 years; and, to describe perceptions around body shape at age 17 years. A total of 1435 urban South African black and mixed ancestry boys and girls, who had data at both age 13 and 17 years from the Birth to Twenty cohort were included. Data were collected through self-administered questionnaires on eating attitudes (EAT-26), body esteem and weight control behaviours for either weight loss or muscle gain attempts. Height and weight were measured at both time points and BMI was calculated. Black females had a higher BMI (p<0.001) and an increased risk of developing eating disorders as well as significant increase in the prevalence of weight loss practices between the ages 13 and 17 years. At age 17 years both Mixed ancestry adolescents had lower body-esteem compared to black adolescents. The prevalence of possible eating disorders was 11% and 13.1% in early and late adolescents respectively. Males and females shared similar opinions on normal silhouettes being the ‘best’, ‘getting respect’ and being the ‘happiest’, while the obese silhouette was associated with the ‘worst’ and the ‘unhappiest’, and the underweight silhouette with the “weakest”. Black females had a higher BMI and an increased risk of developing eating disorders. Adolescent females engaged more in weight loss practices whereas, males in muscle gain practices indicating that Western norms of thinness as the ideal are becoming more common in South Africa.     

Physical attractiveness of face and body as indicators of physical fitness in men

Human physical attractiveness appears to be an important signal of mate value that is utilized in mate choice We argue that performance-related physical fitness (PF) was an important facet of ancestral male mate value and, therefore, that a positive relationship exists between PF and physical attractiveness as well as mating success. We investigated these relationships in a sample of 80 young men. In line with our predictions, we found that (i) a composite measure of PF correlated substantially with body attractiveness (r=.43, after controlling for confounds) but not with facial attractiveness; (ii) PF was positively related to various measures of self-reported mating success (r_S ≈ .22); (iii) the relationship between PF and self-reported mating success was partly mediated by body attractiveness. We conclude it is a key function of men's body attractiveness to signal their PF and that men's faces and bodies signal different facets of mate value.     

Facial attractiveness is related to women's cortisol and body fat,but not with immune responsiveness

Recent studies suggest that facial attractiveness indicates immune responsiveness in men and that this relationship is moderated by stress hormones which interact with testosterone levels. However, studies testing whether facial attractiveness in women signals their immune responsiveness are lacking. Here, we photographed young Latvian women, vaccinated them against hepatitis B and measured the amount of specific antibodies produced, cortisol levels and percentage body fat. Latvian men rated the attractiveness of the women''s faces. Interestingly, in women, immune responsiveness (amount of antibodies produced) did not predict facial attractiveness. Instead, plasma cortisol level was negatively associated with attractiveness, indicating that stressed women look less attractive. Fat percentage was curvilinearly associated with facial attractiveness, indicating that being too thin or too fat reduces attractiveness. Our study suggests that in contrast to men, facial attractiveness in women does not indicate immune responsiveness against hepatitis B, but is associated with two other aspects of long-term health and fertility: circulating levels of the stress hormone cortisol and percentage body fat.     

The effect of maternal obesity on self-esteem and body image

Abstract stress, dissatisfaction and the feeling of inadequacy experienced as a result of the change in appearance caused by weight gain affects self -esteem and body image of pregnant women negatively. The aim of this study was to determine the relationship between maternal obesity, self-esteem and body image. The study was performed through a questionnaire in a state hospital in Trabzon, Turkey with 300 unselected pregnant women who were recruited from the delivery unit. As data collection tools, Body Image Scale (BAS) and Coopersmith Self-Esteem Scale (GIS) were used between April and May 2016. According to BMI variables, 12.3%, 57.0% and 30.7% of the pregnant women were normal, overweight and obese respectively and gained an average of 12.11?±?3.03?kg during pregnancy. Accordingly, the majority of pregnant women who participated in this study were found to be overweight and obese. While the body image of pregnant women surveyed in this study was at a high level (158.84?±?21.34), their average self-esteem was found at a moderate level (64.01?±?15.88). Based on BMI, 56.8% of the women with normal weight perceived themselves as normal, 48.0% of overweight women perceived themselves as normal and 53.3% of obese women perceived themselves as overweight. There was a positive significant relationship between participants' body image and their BMI (r?=?0.119 p?<?0.05). The pregnant women with normal BMI were more likely to feel satisfied. While 56.8% of the pregnant women at normal weight based on BMI were found to feel satisfied and 43.3% of those overweight felt satisfied, 54.3% of obese ones did not feel satisfied. A weak positive significant correlation was found between body image and self-esteem (r?=?0.172; p?=?0.003?<?0.05). As the self-esteem increases, body image increases, too. It was found that the majority of pregnant women were overweight and obese according to BMI and their average body image and self-esteem were high and medium level respectively.     

Measuring outcomes in plastic surgery: body image and quality of life in abdominoplasty patients

Abdominoplasty is an increasingly common aesthetic surgery procedure that has yet to be evaluated using the most recently developed and psychometrically sophisticated measures of body image and quality-of-life outcomes. This study prospectively evaluated 30 consecutive female abdominoplasty patients, preoperatively and postoperatively, using measures of body image, psychological investment in appearance, and general psychosocial functioning. One-way repeated-measures (pretest versus posttest) analyses of variance revealed significant positive postsurgical changes on the Appearance Evaluation subscale of the Multidimensional Body-Self Relations Questionnaire. Mean scores for the questionnaire's Body Areas Satisfaction Scale improved postoperatively (p < 0.001). Scores for the Body Exposure and Sexual Relations Questionnaire also improved significantly (p < 0.001) postoperatively. These findings indicate significant improvements in body image outcome, including positive changes in patients' evaluations of their overall appearance, their average body image dissatisfaction, and their experiences of self-consciousness and avoidance of body exposure during sexual activities. As predicted, no changes were seen on any measure of psychological investment in appearance or on patients' reports of general psychosocial functioning (self-esteem, satisfaction with life, or social anxiety).     

Is sociopolitical egalitarianism related to bodily and facial formidability in men?

Social bargaining models predict that men should calibrate their egalitarian attitudes to their formidability and/or attractiveness. A simple social bargaining model predicts a direct negative association between formidability/attractiveness and egalitarianism, whereas a more complex model predicts an association moderated by wealth. Our study tested both models with 171 men, using two sociopolitical egalitarianism measures: social dominance orientation and support for redistribution. Predictors included bodily formidability and attractiveness and four facial measures (attractiveness, dominance, masculinity, and width-to-height ratio). We also controlled for time spent lifting weights, and experimentally manipulated self-perceived formidability in an attempt to influence egalitarianism. Both the simple and complex social bargaining models received partial support: sociopolitical egalitarianism was negatively related to bodily formidability, but unrelated to other measures of bodily/facial formidability/attractiveness; and a formidability-wealth interaction did predict variance in support for redistribution, but the nature of this interaction differed somewhat from that reported in previous research. Results of the experimental manipulation suggested that egalitarianism is unaffected by self-perceived formidability in the immediate short-term. In sum, results provided some support for both the simple and complex social bargaining models, but suggested that further research is needed to explain why male formidability/attractiveness and egalitarianism are so often negatively related.     

The Influence of Social Norms upon Behavioral Expressions of Implicit and Explicit Weight-Related Stigma in an Interactive Game

This research explored the roles of social influence and stigma-related attitudes in how people behaved toward an overweight female in an interactive computer game. Photographs were used to manipulate whether one of the players in the game was overweight or average weight. We found that both explicit and implicit anti-fat attitudes influenced interactions with an overweight player, but only when other players ostracized the overweight player, not when they included her. Under conditions of ostracism, explicit attitudes were better predictors of more controllable behaviors, while implicit attitudes were better predictors of more automatic behaviors.     

Female college students and cosmetic surgery: an investigation of experiences, attitudes, and body image

This large, multisite study investigated female college students' experiences with and attitudes about cosmetic surgery. The study also assessed the relationship between several aspects of body image, including appearance satisfaction and investment and symptoms of body dysmorphic disorder, and interest in cosmetic surgery. Thirty (5 percent) of the 559 women surveyed reported that they had undergone cosmetic surgery. Two thirds of respondents reported knowing someone who had received cosmetic surgery, and approximately one third indicated that a family member had undergone surgery. Overall, participants held relatively favorable attitudes about surgery. Regression analysis suggested that a greater psychological investment in physical appearance and greater internalization of mass media images of beauty predicted more favorable attitudes toward cosmetic surgery. Fourteen women (2.5 percent) screened positive for body dysmorphic disorder based on the nature and severity of their self-reported body-image concerns. Results of this study provide new information on young women's experiences and attitudes about cosmetic surgery and how these attitudes relate to body image.
