Internalization of ideal body shapes in 9-12-year-old girls

Longitudinal Associations among Identity, Internalization of Appearance Ideals, Body Image, and Eating Disorder Symptoms in Community Adolescents and Emerging Adults: Adaptive and Maladaptive Pathways

Previous research examined the role of identity confusion and body dissatisfaction in eating disorder symptoms, but an integrative perspective including identity synthesis and positive body image is lacking. The current study used three-wave longitudinal data (T1: N = 403; 52.1% female; Mage = 14.85, SD = 0.89) spanning two years to examine the directionality of effects among identity, internalization of appearance ideals, body image, and eating disorder symptoms, with attention to adaptive mechanisms. Results revealed a maladaptive pathway in which internalizing appearance ideals posed a risk for body dissatisfaction and eating disorder symptoms. Conversely, an adaptive pathway highlighted the potential protective role of positive body image regarding identity formation and internalization of appearance ideals. This study provides further insight into the critical role of appearance ideal internalization in the development of eating disorders and the potential value of positive body image. Future research and prevention/intervention efforts should focus on promoting resilience to appearance ideal internalization and enhancing positive body image in the context of identity struggles and eating disorder symptoms.

Testing the Identity Disruption Model among Adolescents: Pathways Connecting Adverse Childhood Experiences to Body Dissatisfaction

The Identity Disruption Model posits that early adversity is associated with lower self-concept clarity, which in turn increases vulnerability to sociocultural appearance factors and body dissatisfaction, but this model has not previously been tested among adolescents. Testing the model during adolescence is critical because this is a key point of development of both identity and body dissatisfaction. This paper presents two studies with adolescents recruited through social media (Study 1: n = 213; 78% female; mean age = 15.7 years, SD = 1.14) and from high schools (Study 2; n = 228; 43% female; mean age = 13.8 years, SD = 1.15). In both studies, self-reported early adversity was associated with lower self-concept clarity; lower self-concept clarity was associated with greater internalization of appearance ideals and more frequent appearance comparisons; and internalization and appearance comparisons were associated with greater body dissatisfaction. This research builds on previous sociocultural models of body dissatisfaction by pointing to processes that occur early in life that could be potential targets of intervention and prevention efforts.

Factorial Model of Obese Adolescents: The Role of Body Image Concerns and Selective Depersonalization-A Pilot Study

BACKGROUND

The relationship binding body weight to psychological well-being is unclear. The present study aims at identifying the contribution, and specificity, of some dimensions (i.e., eating-related symptoms, body image disorders, eating habits, personality traits, and emotional difficulties) characterizing the psychological profile of obese adolescents (749 participants, 325 females; 58.3% normal-weight, 29.9% overweight, and 11.7% obese; mean age = 16.05, SD = 0.82).

METHODS

By introducing the scores obtained by standardized self-report tools into a generalized linear model, a factorial reduction design was used to detect the best fitting discriminant functions and the principal components explaining the higher proportion of the variance.

RESULTS

We found two discriminant functions correctly classifying 87.1% of normal-weight, 57.2% of overweight, and 68.2% of obese adolescents. Furthermore, two independent factors, explaining 69.68% of the total variance, emerged.

CONCLUSIONS

The first factor, "Body Image Concerns", included the drive for thinness, body dissatisfaction, and interpersonal distrust. The second factor, "Selective Depersonalization", included a trend toward depersonalization and dissatisfaction with the torso. The neurophysiological implications of our findings will be discussed.

Can realistic dolls protect body satisfaction in young girls?

Ultra-thin fashion dolls may represent a risk factor for thin-ideal internalisation and body dissatisfaction amongst young girls. We asked thirty one 5- to 9-year-old girls to engage in interactive play with commercially available dolls which were either ultra-thin (Barbie and Monster High) or represented a putative realistic childlike shape (Lottie and Dora) and to indicate their perceived own-body size and ideal body size on an interactive computer task both before and after play. There was a significant interaction between testing phase and doll group such that playing with the ultra-thin dolls led to the girls' 'ideal self' becoming thinner. A further 46 girls played with the ultra-thin dolls and then played with either the same dolls again, the realistic childlike dolls, or with cars. Initial play with the ultra-thin dolls again produced a drop in perceived ideal own body size; however, no group showed any significant change in their body ideals during the additional play phase. These data indicate the potential benefit of dolls representing a realistic child body mass to young girls' body satisfaction and do not support the hypothesis that the negative impacts of ultra-thin dolls can be directly countered by other toys.

Media influence components as predictors of children's body image and eating problems: A longitudinal study of boys and girls during middle childhood

Body image problems are reported during middle childhood and are associated with exposure to appearance-focused media. This longitudinal study investigated the extent to which three media influence components, Awareness, Pressure, and Internalization of media ideals, predict body image and eating problems in children and whether gender moderates this effect. A total sample of N = 688 participants (46 % girls, aged 8-11 at T1) was studied. Self-report questionnaires were administered on the media influence components, body image and eating problems at T1 and T2 (1 year later). After controlling for age, adjusted body mass index and baseline levels of body image and eating problems, results show that media influence components significantly predicted Restraint and Concerns about Eating, Weight, and Shape one year later. Awareness, however, uniquely predicted increases in Eating Concerns in boys, while Pressure predicted increases in Concerns on Eating, Weight, and Shape in girls only. The current results indicate that media influences, some of which may be gender-specific risk factors, predict subsequent body image concerns of girls and boys during middle childhood. Thus, both boys and girls should be addressed in future research and prevention programs.

Digital food marketing to children: How an influencer's lifestyle can stimulate healthy food choices among children

While influencer marketing has been shown to be effective at promoting food low in nutritional value among children, it is less clear whether influencers can also be used to promote healthy nutrition. This article reports on the results of an experimental study on whether and how influencer marketing on Instagram can be deployed to stimulate healthy eating behavior among children. In particular, the study examines whether signaling a healthy, athletic lifestyle can affect children's healthy snack choice (i.e., choice of a snack high in nutritional value). To do so, a two (influencer lifestyle: sedentary versus athletic) by two (snack type: low in nutritional value versus high in nutritional value) between-subjects experiment was conducted among 190 children between eight and 12 years. The results show that promoting a sedentary lifestyle (compared to an athletic lifestyle) resulted in more children choosing the product high in nutritional value. In addition, the children chose a healthy snack more frequently when an influencer portraying a sedentary lifestyle (compared to an athletic lifestyle) promoted a product low in nutritional value. There were no significant interaction effects of influencer lifestyle and snack type on the evaluation of the influencer. However, the study did show that there was less admiration for the influencer when they portrayed a sedentary lifestyle versus an athletic lifestyle.

Becoming an object: A review of self-objectification in girls

Objectification theory (Fredrickson & Roberts, 1997) provides a framework for understanding how cultural pressure on women's appearance (i.e., sexual objectification) impacts their psychological and physical well-being. Although objectification theory proposes that objectification processes commence with the onset of puberty, much of the existing research on self-objectification has been conducted with adult women. Thus, less is known about how self-objectification operates with younger girls and adolescent girls. In this paper, we provide a comprehensive review of self-objectification research on girls under the age of 18 including the prevalence, predictors, and outcomes of self-objectification as well as protective factors (n = 66 studies). In addition, we discuss how development is relevant to objectification theory and self-objectification. Finally, we call for a program of research that addresses methodological and conceptual concerns in existing research, fills gaps in the research literature, and pays further attention to developmental processes in self-objectification. An especially notable pattern we identified is that self-objectification is strongly related to age, such that older girls experience higher levels of self-objectification compared to younger girls. The aim of this paper is to provoke deeper considerations of development and the inclusion of girls in future research on self-objectification.

Factors associated with body dissatisfaction among the Lebanese population

OBJECTIVE

To evaluate the factors associated with body dissatisfaction among the Lebanese population, including sociodemographic characteristics, self-esteem, stress, anxiety, depression, emotional regulation, emotional eating and the adult attachment style.

METHODS

This cross-sectional study, conducted between January and May 2018, enrolled 811 adult participants from all districts of Lebanon. The body dissatisfaction subscale of the eating disorder inventory version 2 (EDI-2) was used to measure body disturbance.

RESULTS

The mean age of the participants was 27.59 ± 11.76 years, with 66.5% females. The final model of the regression analysis showed that a higher binge eating score (Beta = 0.202), being married (Beta = 1.233), having a family history of eating disorders (Beta = 1.933), higher BMI (Beta = 0.076), dieting to lose weight (past 30 days) (Beta = 2.345), receiving comments from the family (Beta = 2.234) and pressure from TV/magazines to lose weight (Beta = 1.320), vomiting or taking laxatives to lose weight (past 30 days) (Beta = 1.861), higher depression (Beta = 0.103) and higher perceived stress (Beta = 0.107) were associated with a higher body dissatisfaction score. However, higher self-esteem (Beta = - 0.246), increased physical activity (Beta = - 0.022) and being divorced (Beta = - 4.226) were significantly associated with a lower body dissatisfaction score.

CONCLUSION

A significant association was found in this current study between the main variables: depression, self-esteem, social anxiety, eating disorders, family and television pressure and body image dissatisfaction.

Appearance-related themes in children's animated movies released between 2004 and 2016: A content analysis

Research suggests that children demonstrate an awareness of cultural messages regarding appearance; specifically, that thinness is desirable and fatness is objectionable. In 2004, Herbozo and colleagues published research examining the content of popular children's movies. This widely cited study has provided the foundation for various studies examining the impact of media on children. The purpose of the current study was to extend the findings of Herbozo et al.'s (2004) research to include more recent movies. Two independent coders viewed the 25 top-grossing U.S. animated feature films since 2004 and indicated the number of appearance-related themes present in each movie. Movies in the current study contained significantly more appearance-related themes focused on male muscularity and the role of personal control related to weight compared to earlier films. These findings are consistent with cultural trends and demonstrate the importance of continued examination of children's media influences.

Dietary Habits and Eating Practices and Their Association with Overweight and Obesity in Rural and Urban Black South African Adolescents

The aim of this study was to investigate differences/similarities in dietary habits and eating practices between younger and older, rural and urban South African adolescents in specific environments (home, community and school) and their associations with overweight and obesity. Dietary habits, eating practices, and anthropometric measurements were performed on rural (n = 392, mean age = 13 years) and urban (n = 3098, mean age = 14 years) adolescents. Logistic regression analysis was used to examine the associations between dietary habits and eating practices, with overweight and obesity risk. Differences in dietary habits and eating practices by gender and by site within the three environments were identified. After adjusting for gender, site, dietary habits, and eating practices within the home, community and school environment, eating the main meal with family some days (OR = 1.78, 95% CI = 1.114-2.835; p ≤ 0.02), eating the main meal with family almost every day (OR = 1.61, 95% CI = 1.106-2.343; p ≤ 0.01), and irregular frequency of consuming breakfast on weekdays (OR = 1.38, 95% CI = 1.007-1.896; p ≤ 0.05) were all associated with increased risk of overweight and obesity. For "Year 15" adolescents, irregular frequency of consuming breakfast on weekends within the home environment (OR = 1.53, 95% CI = 1.099-2.129, p ≤ 0.01), was associated with increased risk of overweight and obesity. For both early- and mid-adolescents, being male (OR = 0.401, 95% CI = 0.299-0.537; p ≤ 0.00; OR = 0.29, 95% CI = 0.218-0.397; p ≤ 0.00) was associated with reduced risk of overweight and obesity, while residing in a rural setting (OR = 0.55, 95% CI = 0.324-0.924; p ≤ 0.02) was associated with reduced risk of overweight and obesity only among early-adolescents. Only dietary habits and eating practices within the home environment were associated with increased risk of overweight and obesity.

The Development of Body Image and Weight Bias in Childhood

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

A serial mediation model testing early adversity, self-concept clarity, and thin-ideal internalization as predictors of body dissatisfaction

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.

Exposure to Barbie: Effects on thin-ideal internalisation, body esteem, and body dissatisfaction among young girls

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.

Perceived Body Image, Eating Behavior, and Sedentary Activities and Body Mass Index Categories in Kuwaiti Female Adolescents

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

YouTube Video as Health Literacy Tool: A Test of Body Image Campaign Effectiveness

This study examined the effectiveness of four media campaigns about disordered eating behaviors. It investigated possible factors that affected females' perceived effectiveness of four campaign videos. Results indicated that health campaign about a celebrity's struggle with extreme thinness proved to be the least effective of four campaign videos, whereas the video presenting solid facts about the dangers of extreme dieting was perceived as the most effective campaign. Self-discrepancy was not a significant predictor to females' perceived effectiveness of campaign videos. Similarly, the frequency of Internet usage was proved as a weak predictor of their perceived effectiveness. These findings and the possible rationale for the lack of support with regard to the correlates of campaign effectiveness were also discussed.

Does maternal psychopathology increase the risk of pre-schooler obesity? A systematic review

The preschool years may be a critical period for child obesity onset; however, literature examining obesity risk factors to date has largely focused on school-aged children. Several links have been made between maternal depression and childhood obesity risks; however, other types of maternal psychopathology have been widely neglected. The aim of the present review was to systematically identify articles that examined relationships between maternal psychopathology variables, including depressive and anxiety symptoms, self-esteem and body dissatisfaction, and risks for pre-schooler obesity, including weight outcomes, physical activity and sedentary behaviour levels, and nutrition/diet variables. Twenty articles meeting review criteria were identified. Results showed positive associations between maternal depressive symptoms and increased risks for pre-schooler obesity in the majority of studies. Results were inconsistent depending on the time at which depression was measured (i.e., antenatal, postnatal, in isolation or longitudinally). Anxiety and body dissatisfaction were only measured in single studies; however, both were linked to pre-schooler obesity risks; self-esteem was not measured by any studies. We concluded that maternal depressive symptoms are important to consider when assessing risks for obesity in preschool-aged children; however, more research is needed examining the impact of other facets of maternal psychopathology on obesity risk in pre-schoolers.

Contemporary girlhood: maternal reports on sexualized behaviour and appearance concern in 4-10 year-old girls

It is widely accepted that the sexualization of girls has increased markedly over time. The overall aim of the present study was to offer a description of the behaviours of young girls, with a particular focus on potentially sexualized behaviours and appearance concern. A sample of 815 mothers of 4-10 year-old girls completed a questionnaire about a range of behaviours exhibited by their daughters, in addition to measures of their own self-objectification and material concern. It was found that many girls engaged with teen culture and used a variety of beauty products, but few exhibited more overtly sexualized behaviours. Involvement with teen culture, using beauty products, attention to clothes, and personal grooming were all associated with the measure of appearance concern, as were maternal self-objectification and material concern. It was concluded that young girls do engage in 'grown up' behaviours and that such engagement is not benign for their development.

Self-objectification, body image disturbance, and eating disorder symptoms in young Australian children

Self-objectification has been examined extensively in adult populations. Despite theoretical evidence suggesting that children may also be vulnerable to experiencing self-objectification, whether children do self-objectify has not been determined. Accordingly, the present study examined the degree to which children self-objectify. The prevalence of body image and eating disturbances in this population, and the relationship between self-objectification and these disturbances, were also investigated. Results from over 250 boys and girls aged 6-11 years revealed that young girls report levels of self-objectification that are similar to those observed among older girls and women. Self-objectification was also found to be meaningfully related to body image and eating disturbances in children. A significant proportion of children reported body dissatisfaction and a minority engaged in disordered eating behaviours in the four weeks prior to the assessment. These results suggest that children may be at risk of experiencing the negative psychological outcomes associated with self-objectification.

Changes in 10-year-old children's body esteem: a time-lag study between 2000 and 2010

This time-lag study examined if there has been any changes in body esteem over a 10-year period for 10-year old children in Gothenburg, Sweden. Two cohorts of children, one in year 2000 and one in 2010, answered the same questionnaire about body esteem. A total of 960 children, 515 girls and 445 boys, participated in the first wave in 2000 and a total of 342 children, 171 girls and 171 boys participated in the second wave in 2010. The results showed a general stability in levels of body esteem for both girls and boys over the past 10 years. The gender differences, with boys being more satisfied with their appearance and weight compared to girls also seems to be stable over the years. In addition, the results also showed a somewhat positive development among the overweight girls with enhanced body esteem for the overweight girls compared to the non-overweight girls during the ten years studied. Unfortunately, the same pattern was not found for overweight boys. For them the discrepancy in body esteem compared to non-overweight boys, with the overweight boys being more dissatisfied, found in 2000 remained in 2010.

The relationship between mothers’ thin-ideal and children’s drive for thinness: A survey of Japanese early adolescents and their mothers

We examined the association of mothers’ thin-ideal internalization and children’s drive for thinness. Early adolescents (175 girls and 198 boys) completed a questionnaire to assess their drive for thinness and perceptions of mothers’ attitudes and behaviors related to body shape. The questionnaire for mothers ( n = 206) measured mothers’ thin-ideal internalization. Mothers’ thin-ideal internalization was associated with girls’ drive for thinness through the perception of mothers’ attitudes directed to girls, and with boys’ drive for thinness through mothers’ weight-loss behavior. The findings suggest the possibility that mothers transmit social standards on body shape to their children.

Sobrepeso y obesidad en preadolescentes mexicanos : estudio descriptivo, variables correlacionadas y directrices de prevención

El sobrepeso y la obesidad representan serios problemas de salud pública. Se realizó un estudio descriptivo y correlacional de variables asociadas al sobrepeso y la obesidad en preadolescentes mexicanos escolarizados en México DF. Se valoró la Autoestima general (LAWSEQ, por sus siglas en inglés), Autoestima corporal (BES, por sus siglas en inglés), Actitudes hacia la alimentación (ChEAT, por sus siglas en inglés) e Imagen corporal (BIA, por sus siglas en inglés) y comparaciones por género y edad. La muestra fue de 600 alumnos, niños y niñas de entre nueve y doce años. Se encontró una baja autoestima general (más baja en las niñas y en los participantes de mayor edad) y corporal y una buena actitud hacia la alimentación. Los participantes se percibieron y creyeron ser vistos con sobrepeso y obesidad, pero a futuro e idealmente desearon figuras más delgadas. Se propone que los programas de prevención contemplen educación para la salud, actividad física, control de aspectos genéticos, actitudes funcionales (tendientes a una buena autoestima y actitudes positivas hacia la comida sana), e involucramiento de la familia y el entorno social.

Thinking meta-theoretically about the role of internalization in the development of body dissatisfaction and body change behaviors

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.

Body dissatisfaction and disordered eating attitudes in 7- to 11-year-old girls: testing a sociocultural model

We examined the sociocultural model of body dissatisfaction and disordered eating attitude development in young girls for the first time. According to the model, internalizing an unrealistically thin ideal body increases the risk of disordered eating via body dissatisfaction, dietary restraint, and depression. Girls aged 7-11 years (N=127) completed measures of thin-ideal internalization, body dissatisfaction, dieting, depression, and disordered eating attitudes. Participants' height and weight were measured and their body mass index calculated. Thin-ideal internalization predicted disordered eating attitudes indirectly via body dissatisfaction, dietary restraint, and depression; it also predicted disordered eating attitudes directly. Path analyses showed that a revised sociocultural model fit well with the data. These data show that a sociocultural framework for understanding disordered eating and body dissatisfaction in adults is useful, with minor modifications, in understanding the development of related attitudes in young girls.

Communicating stigma about body size

Body-size stigma is a well-documented phenomenon, particularly for large bodies (Puhl & Brownell, 2003), but few studies have investigated the features of body-related stigma communication. This article uses Smith's (2007a) stigma communication framework to analyze descriptions of male and female bodies of various sizes for their stigma content. Analyses reveal that elements of stigma communication appeared in 46.5% of comments across all bodies. The most common elements of stigma communication were severe labeling and negative comparison to body ideals. The most stigmatized body was the large male body; the second most stigmatized body was the very small female body. This article shows that stigmatizing communication occurs across the spectrum of body sizes for both genders. The implications of weight-based stigma communication on emotional and physical health are discussed. Implications for future health communication interventions aimed at decreasing body size stigma are presented.

Beautiful From the Inside Out

The goal of the present study was to design, implement, and evaluate a school-based programme that aimed to increase self-esteem and positive body image among preadolescent boys and girls. Participants in grades five and six ( N = 77; Mage = 10.86, 53.2% girls) from a public school in Eastern Ontario completed a battery of validated measures to assess factors related to self-esteem and body image, one week before and one week after the programme. Results indicated that, for both boys and girls, participation in the programme was associated with significantly higher levels of self-esteem and positive body image. The programme was also effective in making participants significantly more aware but less accepting of the distorted and unrealistic body ideals perpetuated by the media. Findings support a new approach for improving body image among Canadian preadolescents. Implications for educators, researchers, and clinicians are discussed.

Muscular fitness, body composition and physical self-perception in adolescents

The primary aim of this study was to investigate gender differences in the relationship between muscular strength, body composition, and physical self-perception in adolescents. Participants (n=106, age 15.0±0.7 years, 51% boys) completed the following assessments: height and weight, bio-electrical impedance analysis (body fat %), muscular strength (1RM bench press and leg press), and the Children's Physical Self-Perception Profile. Bivariate correlations were examined and mediation analysis was used to explore if physical self-perception sub-domains mediated the relationship between muscular strength/adiposity and overall physical self-worth. Among boys, physical self-worth was associated with absolute total strength (r=0.36, p<0.01), but not with body fat % (r=-0.11, p=0.44), or relative total strength (r=0.21, p=0.13). In adolescent girls, physical self-worth was associated with body fat % (r=-0.42, p<0.01), relative total strength (r=0.40, p<0.01) but not absolute total strength (r=0.07, p=0.62). In boys, perceived physical strength mediated the relationship between absolute muscular strength and physical self-worth. Relative muscular strength was not associated with perceived strength (p>0.05) in girls and the test of the mediated effect was non-significant (p>0.05). Perceived body attractiveness was found to mediate the relationship between body fat % and physical self-worth among boys and girls. Physical self-worth is associated with different components of health-related fitness in adolescent girls and boys. Mediation analysis can be used to provide insights into the complex interrelationships between variables.

Construção e fidedignidade teste-reteste de escalas de silhuetas brasileiras para adultos e crianças

O objetivo deste trabalho foi desenvolver escalas de silhuetas para crianças e adultos brasileiros de ambos os sexos e iniciar a avaliação de suas qualidades psicométricas. Foram fotografados adultos e crianças com Índice de Massa Corporal (IMC) previamente conhecidos, desenhadas as silhuetas e construídas as escalas por computação gráfica. Para avaliação da fidedignidade, procedeu-se ao teste-reteste com intervalo de um mês. As escalas foram aplicadas e reaplicadas a 90 adultos (18 a 60 anos) e 69 crianças (7 a 12 anos). As escalas apresentaram coeficientes de correlação entre teste e reteste positivos e significativos para o IMC real e IMC percebido como atual por adultos (r=0,84; p<0,01) e crianças (r=0,61, p<0,01). Concluiu-se que as escalas desenvolvidas constituem instrumentos apropriados à aplicação clínica e epidemiológica para avaliar a percepção da imagem corporal de crianças e adultos brasileiros.

Telling parents their child's weight status: psychological impact of a weight-screening program

OBJECTIVE

This was a descriptive study examining the psychological impact of a school-based, weight-screening intervention that included feedback to parents.

METHODS

Children from years 3 and 6 (6-7 and 10-11 years old) in London schools were measured in school, and parents were sent information on the child's weight status. Children and parents completed questionnaires 6 weeks before and 4 weeks after the feedback; 358 children and 287 parents completed both questionnaires. The main outcome measures (parental feeding practices, parental perception of child weight, child body esteem, child eating behavior, and weight-related teasing) were assessed before and after feedback. Qualitative data on health-behavior change and parents' and children's views of the measurement and feedback process were collected at follow-up.

RESULTS

Fifty-one percent of the parents (n = 398) volunteered for child measurements and weight feedback. Feedback was not associated with changes in child feeding among parents of healthy-weight children, but dietary restriction increased in parents of overweight girls. Among healthy-weight children, restrained eating decreased and body esteem increased, but there were no significant changes among the overweight group and no changes in reports of teasing. Perceptions of child overweight did not increase significantly, but 50% of the parents of overweight children reported positive changes in health behaviors. The majority (65%) of parents wanted weight feedback on a regular basis, and most children enjoyed the measuring process.

CONCLUSIONS

Weight feedback was acceptable to the majority of parents participating in an "opt-in" measurement and feedback program; adverse effects were minimal for children and parents, even when feedback indicated overweight. However, a minority of participants found it distressing, which highlights the importance of managing the process sensitively, particularly for families with overweight children.

Validation and predictive utility of the Sociocultural Attitudes Toward Appearance Questionnaire for Eating Disorders (SATAQ-ED): internalization of sociocultural ideals predicts weight gain

A widely used measure of societal influences on body image and eating disturbances--the Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ) was validated in women with eating disorders. The original SATAQ and measures of convergence and divergence were administered to 165 eating disordered inpatients. Factor analyses were conducted to determine the underlying structure of the SATAQ. Convergent validity, diagnostic category norms and the predictive utility of the revised SATAQ were examined. Factor analyses indicated three factors: Internalization, Awareness, and Success. Internalization significantly predicted treatment success after controlling for admission BMI and drive for thinness. The revised SATAQ-ED measures multiple aspects of societal influence, predicts short-term outcome, and can be a useful tool for evaluating potential outcome and treatment efficacy.

Thin ideal internalization in Mexican girls: a test of the sociocultural model of eating disorders

OBJECTIVE

We examined the influence of thin ideal internalization on body dissatisfaction and disordered eating in Mexican girls.

METHOD

We sampled 137 public school girls aged 12-15 from a small city in Mexico. Participants were given Spanish versions of the sociocultural attitudes toward appearance scale, two measures of body dissatisfaction, the eating attitudes test, and the attitudinal familism scale.

RESULTS

Thin ideal internalization mediated the relationship between thin ideal awareness and body dissatisfaction, and the relationship between thin ideal awareness and eating disorder symptoms. Attitudinal familism was negatively correlated with thin ideal internalization for girls outside of the normal weight range.

CONCLUSION

Mexican girls are at risk of eating disorder symptoms, and there is support for the sociocultural model of disordered eating in this population. Hispanic family values may mark protection from thin ideal internalization in Mexican girls outside of the normal weight range.

Assessment of adolescent body perception: development and characterization of a novel tool for morphing images of adolescent bodies

We developed a computer-based method of distorting adolescent body images, which incorporates the covariation between body parts found during growth and sexual maturation. An adolescent body-shape database (AdoBSD) and adolescent body morphing tool (AdoBMT) are described; the AdoBSD comprises real (n=320) and morphed (n approximately 41,000) images (front and side view) of 160 adolescents (9-17 years). We used a point distribution model, based upon principal components analysis, to characterize the covariation between predefined body tag-points manually positioned on the body images and to morph the body images in a realistic manner. Eight principal components (PCs) were found to characterize 96.3% of the covariation between body tag-point. Application of the PCs to the body images resulted in the manipulation of body parts including shoulder width, waist, hip, belly, thigh and calf sizes. The AdoBMT and AdoBSD may be used to investigate changes in body perception during adolescence, and the role of body perception in adolescent obesity and eating disorders. The AdoBSD is available to the research community (www.brainbody.nottingham.ac.uk).

Insatisfação corporal em escolares de dois municípios da região Sul do Brasil

OBJETIVO: Avaliar a prevalência de insatisfação corporal e fatores associados em escolares de dois municípios de pequeno porte no Sul do Brasil. MÉTODOS: Estudo transversal, realizado com 573 escolares de 8 a 10 anos dos municípios de Dois Irmãos e Morro Reuter, Rio Grande do Sul. Foram coletados dados sobre insatisfação corporal e peso das crianças por meio de escala de imagem corporal (Children's Figure Rating Scale) e antropometria. As mães responderam questionário sobre preocupações e percepções relacionadas ao peso dos filhos. O Índice de Massa Corporal foi utilizado para classificar o estado nutricional. Fez-se análise de regressão logística para avaliar associações entre as variáveis estudadas e a insatisfação corporal. RESULTADOS: A prevalência de insatisfação corporal foi de 63,9%, sendo que 16,9% estavam com sobrepeso. As variáveis associadas com insatisfação corporal foram: risco para obesidade (Odds ratio=2,91; IC95% 1,26-6,74) e obesidade (Odds ratio=4,47; IC95% 1,12-17,9); residir em zona urbana (Odss ratio=1,75; IC95% 1,03-2,97); mães com menos de oito anos de escolaridade (Odds ratio=1,57; IC95% 1,03-2,40); percepções da mãe de que o filho estava abaixo ou acima do peso adequado (Odds ratio=1,65; IC95% 1,05-2,59) e de que ele se preocupava com o peso (Odds ratio=1,53; IC95% 1,05-2,23). CONCLUSÃO: Altos índices de insatisfação com o corpo também são observados em pré-adolescentes de cidades do interior. Os dados gerados por este estudo são suficientes para alertar pais, educadores e profissionais de saúde para a necessidade de desenvolver estratégias que visem a maior satisfação das crianças com o seu corpo.
