The Body and the Beautiful: Health, Attractiveness and Body Composition in Men's and Women's Bodies.

The dominant evolutionary theory of physical attraction posits that attractiveness reflects physiological health, and attraction is a mechanism for identifying a healthy mate. Previous studies have found that perceptions of the healthiest body mass index (weight scaled for height; BMI) for women are close to healthy BMI guidelines, while the most attractive BMI is significantly lower, possibly pointing to an influence of sociocultural factors in determining attractive BMI. However, less is known about ideal body size for men. Further, research has not addressed the role of body fat and muscle, which have distinct relationships with health and are conflated in BMI, in determining perceived health and attractiveness. Here, we hypothesised that, if attractiveness reflects physiological health, the most attractive and healthy appearing body composition should be in line with physiologically healthy body composition. Thirty female and 33 male observers were instructed to manipulate 15 female and 15 male body images in terms of their fat and muscle to optimise perceived health and, separately, attractiveness. Observers were unaware that they were manipulating the muscle and fat content of bodies. The most attractive apparent fat mass for female bodies was significantly lower than the healthiest appearing fat mass (and was lower than the physiologically healthy range), with no significant difference for muscle mass. The optimal fat and muscle mass for men’s bodies was in line with the healthy range. Male observers preferred a significantly lower overall male body mass than did female observers. While the body fat and muscle associated with healthy and attractive appearance is broadly in line with physiologically healthy values, deviations from this pattern suggest that future research should examine a possible role for internalization of body ideals in influencing perceptions of attractive body composition, particularly in women.

Influence of a Body Type Training Program on Body Image Dissatisfaction

Combined aerobic and resistance training (ATRT) programs are recommended to improve fitness; however, a novel training program focused on individual body type (BT) may provide additional benefits to body satisfaction. PURPOSE: To examine body image dissatisfaction (BID) responses after ~7 weeks of BT training or ATRT. METHODS: Participants (age 19±1y; BMI 23.2±3.5) provided self-report measures of BID (Body Area Satisfaction Scale (BASS), Body Shape Questionnaire (BSQ), and Body Morph Assessment version 2.0 (BMA 2.0)) at baseline and after 15 exercise sessions, 2 d/wk. Participants were randomized to BT or ATRT intervention after classification to a Body Type (Cone®, Spoon®, Hourglass®, or Ruler®) according to circumference measures. BMA 2.0 assessed perceived current body size (CBS), selected ideal body size (IBS), selected acceptable body size (ABS), and BMA-BID (CBS-IBS). Given this was an efficacy trial, intent-to-treat (ITT; n=132) and per protocol (PP; BASS, BSQ n=77; BMA n=93; completed ≥ 10 of 15 supervised sessions) data analyses were utilized. RESULTS: Overall, body image scores decreased with a trend observed for the BMA-BID (baseline: 5.5 95%CI(4.5-6.5); follow-up: 4.8 (3.9-5.8); P=0.07) after exercise training indicating improvements in BID. Results were similar among ITT and PP analyses. Increases in BID were seen in the ATRT group with significantly lower BASS scores compared to BT group at follow-up (ATRT= 2.61 vs. 2.45; P < 0.05). Participants in the ATRT group saw themselves as smaller and set a smaller acceptable goals based on significant reductions in CBS and ABS relative to BT. Sum circumferences were different after both programs (BT = -6.2cm; 95% CI -1.9, -10.7cm; ATRT = -7.5cm; -3.3, -11.7cm); however, changes in body satisfaction were not related to changes in total body circumferences (P>0.05 for all). CONCLUSION: Baseline scores for BID suggest women in this study were generally unsatisfied with their overall body image (BASS < 3.0, BSQ > 80). In general, BT and ATRT produced similar responses; exercise reduced CBS—thereby reducing the difference between CBS and IBS—improving overall body satisfaction regardless of changes in body composition.

Ideal Body Size as a Mediator for the Gender-Specific Association Between Socioeconomic Status and Body Mass Index: Evidence From an Upper-Middle-Income Country in the African Region.

While obesity continues to rise globally, the associations between body size, gender, and socioeconomic status (SES) seem to vary in different populations, and little is known on the contribution of perceived ideal body size in the social disparity of obesity in African countries. We examined the gender and socioeconomic patterns of body mass index (BMI) and perceived ideal body size in the Seychelles, a middle-income small island state in the African region. We also assessed the potential role of perceived ideal body size as a mediator for the gender-specific association between SES and BMI. A population-based survey of 1,240 adults aged 25 to 64 years conducted in December 2013. Participants' BMI was calculated based on measured weight and height; ideal body size was assessed using a nine-silhouette instrument. Three SES indicators were considered: income, education, and occupation. BMI and perceived ideal body size were both higher among men of higher versus lower SES (p< .001) but lower among women of higher versus lower SES (p< .001), irrespective of the SES indicator used. Multivariate analysis showed a strong and direct association between perceived ideal body size and BMI in both men and women (p< .001) and was consistent with a potential mediating role of perceived ideal body size in the gender-specific associations between SES and BMI. Our study emphasizes the importance of gender and socioeconomic differences in BMI and ideal body size and suggests that public health interventions that promote perception of healthy weight could help mitigate SES-related disparities in BMI.

Television exposure predicts body size ideals in rural Nicaragua.

Internalization of a thin ideal has been posited as a key risk factor in the development of pathological eating attitudes. Cross-culturally, studies have found a preference for heavier bodies in populations with reduced access to visual media compared to Western populations. As yet, however, there has been little attempt to control for confounding variables in order to isolate the effects of media exposure from other cultural and ecological factors. Here, we examined preferences for female body size in relation to television consumption in Nicaraguan men and women, while controlling for the potential confounding effects of other aspects of Westernization and hunger. We included an urban sample, a sample from a village with established television access, and a sample from a nearby village with very limited television access. The highest BMI preferences were found in the village with least media access, while the lowest BMI preferences were found in the urban sample. Data from the rural sample with established television access were intermediate between the two. Amongst rural women in particular, greater television consumption was a stronger predictor of body weight preferences than acculturation, education, hunger, or income. We also found some evidence for television consumption increasing the likelihood of women seeking to lose weight, possibly via body shape preferences. Overall, these results strongly implicate television access in establishing risk factors for body image disturbances in populations newly gaining access to Western media.

Body size perception and ideal body size in overweight and obese young adult women

Body size perception and ideal body size in overweight and obese young adult women

Body size perception and ideal body size in overweight and obese young adult women.

The purpose of this study was to examine the differences among actual body size, perceived body size, and ideal body size in overweight and obese young adult women. Actual body size was assessed by body mass index (BMI), while self-perceived and ideal body sizes were assessed by the Body image assessment tool-body dimension. Descriptive statistics were calculated and analysis of variance (ANOVA) was performed on actual BMI as a function of perceived BMI. Of the 42 participants included in the study, 12 were overweight (25≤BMI<30), 18 were obese 1 (30≤BMI<35), and 12 were obese 2 (35≤BMI≤39.48). The mean ideal body size of participants was 25.34±1.33. Participants in general perceived their body size (BMI: 35.82±1.06) to be higher than their actual body size (32.84±0.95). Overweight participants had a significantly higher mean body size misperception than obese 2 individuals (µ dif=-6.68, p<.001). Perception accuracy of body size differs in women by BMI. Weight loss programs need to be tailored to consider body size misperception in order to improve treatment outcomes for overweight and obese young women.

A Gender Study on Mexican College Students’ Body-Image Perception

The purpose of the present study is to compare the scores on current, ideal, and social body shape and body size dissatisfaction between Mexican male and female college students. A total sample of 1,497 participants, 739 women and 758 men, aged 18-29 years participated in this study. A quantitative approach with a descriptive and transversal survey design was used. All the participants completed the Contour Drawing Rating Scale. The results of the one-way multivariate analysis of variance, followed by the one-way univariate analyses of variance, showed that compared to men, women expressed a greater discrepancy between ideal and actual body shape and lower score of ideal body shape. However, in the current body shape and social body shape no statistically significant differences were found. Because of the found body-image perception differences between men and women, results suggest that in order to design any intervention for improving students’ perceived body image, the gender variable should be taken into account.

Associations between anxiety, self-efficacy, and outcomes by gender and body size dissatisfaction during fitness in high school physical education

Background: Noteworthy proportions of adolescents – particularly females – report negatively about their experiences regarding fitness and the testing of it during physical education (PE). These accounts often coincide with lower levels of body image, fitness, motivation, and physical activity and higher rates of attrition from optional PE.Purpose: The aim of this study was to test path relations between body size dissatisfaction (BSD), test anxiety (TA), self-efficacy, and fitness-related outcomes during fitness in PE and to determine whether these differ as a function of gender and level of BSD.Method: Survey data were collected from 394 9th and 10th-grade students in southern Ontario, Canada. A previously validated BSD measure was used that consisted of a series of nine gender-specific silhouettes ranging from very thin/slender to very large/overweight. Students’ dissatisfaction score involved subtracting self-ratings of their ideal body size from current body size estimates. Fitness indices in PE (FIPE)was the z-score of the sum of self-reported fitness level, fitness grade in PE, and frequency of active exercise at least 30 minutes per day. Self-efficacy and TA were assessed using established scales from the Motivated Strategies for Learning Questionnaire.Data analysis: Multivariate analysis of variance was used to assess group differences whereas gender-specific confirmatory factor and path analyses were used to test the proposed path in which relations between BSD and FIPE were manifest indirectly through TA and self-efficacy.Findings: The hypothetical path fit the data in the overall sample and fit better for females than for males. Females reported a higher BSD and a lower self-efficacy and FIPE than males. BSD was evident in both genders with most females desiring a thinner body compared to boys who had relatively equal proportions wanting to be bigger and thinner. Males wanting to be smaller reported significantly lower self-efficacy and FIPE than males with little BSD or those wanting to be larger. Females desiring a thinner body reported significantly more TA and lower FIPE than females with no BSD.Conclusion: Body image concerns and elevated levels of anxiety appear to undergird the influence of self-efficacy on FIPE. This is particularly so in females, although both females and males with a BSD are susceptible to lowered fitness motivation and achievement in PE. Suggestions are provided to help physical educators to structure fitness curricula and pedagogy to better minimize this vulnerability. These include catering to the gender-specific needs and preferences for fitness activities during PE including the testing of fitness.

Perceived current and ideal body size in female undergraduates

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

Change in body weight and body image in young adults: a longitudinal study

BackgroundThe goal of this study was to identify the effect of the change in body mass index (BMI) from childhood to adulthood on body image satisfaction at 23 years of age in members of the 1982 Pelotas Birth Cohort in Pelotas, RS, Brazil.MethodsThe study used data from the 1986 and 2004–5 follow-up studies. Body shape satisfaction was evaluated using the Stunkard scale. Body shape dissatisfaction was defined as the difference between the figures chosen for the current and ideal body size. BMI z-score changes were calculated as the difference between z-score values at 4 and 23 years of age, using the population internal z-score as standard. The analysis was stratified by sex, and multinomial logistic regression was used in crude and adjusted analyses.ResultsA total of 1963 men and 1739 women were analyzed. The mean age of the participants in 2004–5 was 22.7 years. Of the participants exhibiting increased BMI z-scores, 17% perceived themselves as thinner than ideal, whereas 48% perceived themselves as fatter than ideal. The prevalence of dissatisfaction was higher in women because they perceived themselves as fatter than ideal on the three categories of z-score change (≥ + 0.5 sd; −0.49 to + 0.49 sd and ≤ −0.5 sd); 81% of women exhibiting an increased BMI z-score reported dissatisfaction. The analysis adjusted for confounding factors revealed that women with increased BMI z-scores were less prone to feel thinner than ideal. Additionally, the increased risk of dissatisfaction due to perceiving oneself as fatter than ideal was similar between men and women (RRR = 3.52 95% CI: 2.17 to 4.56 and RRR = 4.08 95% CI: 3.00 to 5.56, respectively) using −0.49 to +0.49 sd as the reference category.ConclusionsIndividuals exhibiting increased BMI z-scores between 4 and 23 years of age reported higher risks of body dissatisfaction at 23 years of age. This finding is important because body dissatisfaction can cause psychological, social, self-esteem problems, and well-being.

Cultural Influences on Body Size Ideals

Given that an important component of perceptual body dissatisfaction is the discrepancy between ideal and current body sizes, understanding how body size ideals are shaped and transmitted remains an important task for scholars. This review begins by examining cross-cultural patterns of body size ideals. Evidence is presented to indicate that the largest differences in body size ideals are no longer found between Western and non-Western cultures, but between sites differing in socioeconomic status. It is further argued that a thin ideal is now prevalent in most socioeconomically developed, urban sites. In explanation, it has been suggested that both Westernization and modernization bring cultural changes that promote a thin ideal. The present article reviews evidence in favor of both factors and concludes by looking at clinical implications for understanding corporeal experiences in a globalized world.

Relationship between body image, body dissatisfaction and weight status in Iranian adolescents

Background: In current society adolescents are concerned about body image. The relationship between body dissatisfaction and obesity is not clear in developing countries. This study sought to describe body image size perception and dissatisfaction, and their relationship with body weight status in adolescents. Methods: Objective measures of weight and height were undertaken on 1109 schoolchildren aged 10-18 (504 girls and 605 boys). BMI z-scores, and weight status were calculated based on the 2007 WHO growth reference charts. Figure rating scales were used to assess perceptions of current and ideal body size and dissatisfaction difference between these perceptions. Multivariate analyses were used to assess the relationship between the perceptions and dissatisfaction with body weight status. 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 and age). 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 nonoverweight/ obese was 1.47 (95% CI 0.99-1.96) and for BMI z-score was 0.54 (95% CI 0.40-0.67). Conclusions: Awareness of body image size and increasing body dissatisfaction with the higher weight status is established at a young age in this population. This needs to be considered when designing interventions to reduce obesity in young children, in terms of both benefits and harms.

Multiple Perspectives on Body Image Research

Representation of the body is a nuclear aspect of self-image. Body representation includes both subjective and intersubjective experiences. The importance of visual body representation in our social life is demonstrated by the time we spend to take care of our physical appearance, including use of plastic surgery, as well as by the severe mental disorders associated to its alteration, including eating disorders (EDs) and body dysmorphic disorders. In spite of these issues, (neuro)psychological research on body representation has so far mainly focused on the body as a motor device, devoted to the perception of and interaction with objects. The complexity of factors involved in the development, maintenance, and plasticity of body image representations requires an integrated approach that facilitates the evaluation and treatment of EDs with novel, evidence-based, and more efficacious protocols. This special issue of European Psychologist aims to advance such an integrative approach, with a collection of papers that gather different perspectives on the phenomenological, cognitive, (neuro)psychological, and cultural aspects of body representation disorders.

Social trajectory and body image satisfaction in childbearing women.

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

Obesity "epidemic" in the Kingdom of Tonga

In a worldwide obesity pandemic, where a growing number of people all over the world are classified as obese, the fight against obesity has become an international priority. Large funds, numbers of projects and international guidelines for global policies are reaching as far as the South Pacific. This area indeed seems to concentrate the world’s fattest and an obesity epidemic has been declared. Relying on her own fieldwork in the Kingdom of Tonga, the author questions this epidemic by criticizing the mainstream measurements employed to calculate the body weight – the BMI – which standardize one optimal size. She then positions the « war against obesity » in a wider global health frame, where global policies transpose global operating concepts to local contexts and shows that Tongan cultural practices related to food consumption and exposition, beauty and body size ideals, health and social stratification and the local of a « right body » poorly fit them. Moreover, squeezed between international health directives, local economy and trade policies, Tonga sees an increment of the diabetes and cardio-vascular diseases’ rates, addressed as the consequence of a yet to be proven obesity epidemic.

Body Image Disturbances and Predictors of Body Dissatisfaction Among Hispanic and White Preadolescents

This study assessed ethnic and gender differences in ideal body size, body dissatisfaction (BD), and the relationship between BD and various predictors (e.g., body composition indicators and cardiorespiratory fitness). The sample consisted of 190 White and Hispanic preadolescents aged 10–13 years. Demographic, percent body fat (%BF), body mass index (BMI), body image variables, and cardiorespiratory fitness (CRF) were examined. A significant Gender × Ethnicity interaction was found for ideal body size (p < .05), with Hispanic girls preferring the thinnest figures and Hispanic boys the largest figures, compared to their counterparts. No significant gender or ethnic differences in BD were observed. After controlling for demographic and cultural variables, increased %BF and BMI scores predicted greater BD, whereas CRF did not.

Nutritional status of adolescents attending the Iranian secondary school in Kuala Lumpur, Malaysia.

Introduction:The aim or this study was to determine factors associated with body weight status among Iranian adolescents in the two Secondary Schools run by the Embassy in Kuala Lumpur.Methods:A self administered questionnaire was used to assess socio demographic characteristics, physical activity, and body image. Dietary intake was recorded through individual interviews with the researcher. The Physical Activity Questionnaire for children (PAQ-C) was used to evaluate levels of physical activity of the adolescents.Results:One-third (32.2%) of respondents were of normal weight, 14.5% and 11.1% were overweight and obese respectively, while 18.6% and 23.6% were severe thinness and thinness respectively. While the distribution of obese respondents by gender was almost the same, overweight females (16.4%) exceeded overweight males (12.7%) and although more females were in the thinness category (24.7% compared to 22.7%), more males were severely thin (20.0%) compared to 17.1% of the females. Body weight status was significantly associated with age (p < 0.05), gender (p < 0.05) and grade (p < 0.05). Males had significantly higher physically activity scores than females (p < 0.05). Intake of all micronutrients were higher than Dietary Reference Intake (DRI), except for vitamins B1, B2, C, D and E, Folate, Zinc, Magnesium, Potassium, Calcium and Phosphorus. There was a tendency for the females to overestimate their weight and 72.6% of them expressed their desire to lose weight while 60% of the males wanted to gain weight. There was also significant association between body weight status and perception of ideal body size (p = 0.000) and healthy body size (p = 0.000).Conclusion:This study provides some information for the Iranian Secondary school to design intervention programs to improve the body weight status of their students.

Do These Norms Make Me Look Fat? The Effect of Exposure to Others’ Body Preferences on Personal Body Ideals

In this study we examined the influence of normative body ideals in the form of perceived peer preferences on personal body ideals and body dissatisfaction Participants (N=146 female college students) were exposed to the purported preferences of peers representing either relatively thin or heavy body ideals. Along with the normative body ideal manipulation, the gender of the purported peers was manipulated. Participants then selected their ideal for their own body and body dissatisfaction was measured. Women selected a thinner personal body ideal in the thin norm condition than in the heavy norm condition. This effect was seen irrespective of the gender of the purported peers. Body dissatisfaction was not influenced by the manipulation. The malleability of body image and the influence of social factors on ideal body size are discussed.

Identifying the ideal body size and shape characteristics associated with children's physical performance tests in Peru.

We used allometric models to identify the optimal body size/shape characteristics associated with physical and motor performance tests in Peruvian schoolchildren. The sample consisted of 3624 subjects (1669 boys and 1955 girls) aged 11-17 years from 31 public schools belonging to four cities located in the three natural regions in central Peru. Motor performance included 12-min run, standing long jump, grip strength, curl-ups, shuttle run, and sit and reach. The reciprocal Ponderal index (RPI), a characteristic sometimes referred to as the somatotype "ectomorphy," was found to be the most suitable body shape indicator associated with 12-min run, standing long jump, curl-up, and shuttle run performance. A positive maturation offset parameter was also associated with greater standing long jump, grip strength, shuttle run, and sit-and-reach performances. With the exception of the sit-and-reach flexibility, sex differences are pervasive in all tests favoring boys. Rainforest schoolchildren are best performers in the power and flexibility tests, whereas those from high altitude were superior in the 12-min endurance test even after taking their much lighter body size characteristics into account. This latter finding suggests that living at high altitude in Peru benefits children's endurance performance both before and even after controlling for differences in the confounding variable of body size/shape.

The Influence of Television and Film Viewing on Midlife Women's Body Image, Disordered Eating, and Food Choice

A recent trend in screen media is the casting of older women who have bodies that are the shapes and sizes of younger women. These aging beauties can be found in shows such as Cougar Town and Desperate Housewives. It was predicted that heavy viewers of these media would report stronger eating disorder symptomatology, greater body ideal discrepancies, and stricter food choices than light viewers. Participants were 166 midlife women (M: 44.57 years) who completed an online questionnaire that asked about body ideals, disordered eating, food choices, and exposure to aging beauty programming. Results demonstrate that media exposure was associated with stronger reports of disordered eating, greater discrepancies between actual body size and both women's ideal body size as well as perceptions of how others wanted them to look, and stricter food choices when around other people. Ideal self-discrepancies mediate the association between aging beauty media and disordered eating symptomatology. Our study builds on extant work related to media consumption, body concerns, and eating behaviors among a non–college-aged sample.
