Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action

The body image, weight satisfaction, and eating disorder tendency of school children: the 2-year follow-up study

OBJECTIVE

This 2-year follow-up study was conducted to enhance our understanding of changes and rates of disturbed eating attitudes/behaviors, weight satisfaction, and prevalence of obesity in elementary school students between the ages of 10 and 12 years.

METHODS

Questionnaires consisted of the following sections: (A) Demographics, (B) Body image, (C) Pubertal Development Scale, and (D) Children's Eating Attitudes Test-26 (ChEAT-26). School-based randomly selected participants completed the questionnaire at 10 years of age and repeated the same questionnaire 2 years later, at 12 years of age.

RESULTS

The following findings were reported: (1) when changes at 2 years were compared, it was seen that the actual body weight of boys tended to increase, and perceived body size and desired body weight showed significant changes; (2) the percentage of children who wanted to be thinner increased, especially among girls; and (3) the percentage of participants with a tendency toward eating disorders (measured by ChEAT-26, ≥20) decreased from 10.4% to 10.1% in boys, and increased from 10.9% to 12.3% in girls.

CONCLUSION

Nutritional education should emphasize the importance of correct body image and eating attitudes for the prevention of unhealthy body weight concerns and eating disorders in children. Caregivers' attitudes about weight and how caregivers deliver information on weight issues to children should be recognized as important factors related to healthy body image and eating attitudes among children.

The effects of "thin ideal" media on women's body image concerns and eating-related intentions: the beneficial role of an autonomous regulation of eating behaviors

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

Representation of ideal figure size in Ebony magazine: a content analysis

Studies examining trends over time in mainstream magazines observe decreases in women's figure size, and increases in figure exposure and amount of diet/exercise content. Little is known, however, regarding the content of African American magazines. Utilizing methods from classic studies, this investigation examined content in Ebony, a magazine with wide African American readership, from 1969 to 2008. We included the full content of N=462 issues, with a total of N=539 cover images of women, of which N=208 were full-body shots. Analyses indicated a curvilinear relationship between time and figure exposure, with a recent trend toward more full-body shots, similar to mainstream magazines. Contrary to previous studies, however, the majority of figures across time were average size, and a curvilinear relationship between time and diet/exercise content showed peak content in the early 1990s. Results are considered in context of research indicating African American women show less body dissatisfaction than other racial/ethnic groups.

Social psychological theories of disordered eating in college women: review and integration

Because peer interaction, weight/shape, and self-concept formation are particularly salient to college women, the implications of social psychological theories may be especially far-reaching during the college years. College women may be particularly vulnerable to the effects of social comparison, objectification, and uses and gratifications theories, which describe social-cognitive mechanisms that provide an individual with information regarding her own view of her body and how she perceives that others perceive her body. The current paper will review and integrate findings related to these three theories of disordered eating in college women in an effort to present a more comprehensive understanding of the social psychological mechanisms that play a role in the development and maintenance of such pathology for this group of young women. Limitations of and future directions for research on these theories will be discussed, as will their potential integration with other factors that contribute to disordered eating and implications for treatment and prevention.

The Evolution of "Enhanced" Cognitive Behavior Therapy for Eating Disorders: Learning From Treatment Nonresponse

In recent years there has been widespread acceptance that cognitive behavior therapy (CBT) is the treatment of choice for bulimia nervosa. The cognitive behavioral treatment of bulimia nervosa (CBT-BN) was first described in 1981. Over the past decades the theory and treatment have evolved in response to a variety of challenges. The treatment has been adapted to make it suitable for all forms of eating disorder-thereby making it "transdiagnostic" in its scope- and treatment procedures have been refined to improve outcome. The new version of the treatment, termed enhanced CBT (CBT-E) also addresses psychopathological processes "external" to the eating disorder, which, in certain subgroups of patients, interact with the disorder itself. In this paper we discuss how the development of this broader theory and treatment arose from focusing on those patients who did not respond well to earlier versions of the treatment.

Slimming company websites in Hong Kong: implications for women's health

This study sought to investigate, with a focus on the Hong Kong context, how commercial slimming websites portray the body image of beauty to the public, and to explore practical implications for related public health practices and health policy formulation. Commercial entities in the Hong Kong slimming industry were retrieved from the Hong Kong Yellow Page Directory and Yahoo Hong Kong Directory, and selected websites were coded and further analyzed. We found that irresponsible tactics are used in the slimming industry such that irresponsible messages prevail. Collaborative efforts from multidisciplinary sectors are needed to tackle the situation.

Downward spirals of body surveillance and weight/shape concern among African American and Caucasian college women

Within dominant American culture, females often learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at (i.e., self-objectification), which can result in negative outcomes. Body surveillance (the indicator of self-objectification) has been found to predict concern with weight/shape in predominantly Caucasian samples, but research has not yet examined the potential reciprocal relations between body surveillance and weight/shape concern. Participants were 226 women attending a Midwestern university (70 self-identified as African American and 156 as Caucasian) who provided data at two time points, spaced about 5 months apart. Results revealed that downward spirals of body surveillance and weight/shape concern were apparent for the Caucasian but not the African American women. However, there was evidence that body surveillance helped account for change in weight/shape concern for the African American women.

“If You’re Fat, Then I’m Humongous!”

Fat talk (women speaking negatively about the size and shape of their bodies) is a phenomenon that both reflects and creates body dissatisfaction. Our study investigated the content, frequency, and impact of fat talk among college women. Participants (168 female students at a Midwestern U.S. university) completed online surveys containing fat talk-specific questions and measures of body dissatisfaction and thin-ideal internalization. Most participants reported engaging in fat talk with one third reporting frequent or very frequent fat talk. Evidence indicated a strong third-person effect wherein participants thought they engaged in fat talk less than other college women. Self-reported frequency of fat talk was associated with greater body dissatisfaction and internalization of the thin-ideal but not body mass index (BMI). Despite the association between fat talk and body dissatisfaction, over half of the participants reported that they believe fat talk makes them feel better about their bodies. The most common response to fat talk was denial that the friend was fat, most typically leading to a back-and-forth conversation where each of two healthy weight peers denies the other is fat while claiming to be fat themselves. Results are discussed in terms of the ways in which fat talk may act as an injunctive norm, reinforcing women’s body-related distress.

Judging the health and attractiveness of female faces: is the most attractive level of facial adiposity also considered the healthiest?

Perceived facial adiposity plays an important role in perceptions of both facial attractiveness and health, but people might differentiate between the level of adiposity they find most attractive and healthy. The aim of this study was therefore to test whether or not similar levels of adiposity in faces were preferred for judgments of health and attractiveness. Fifty-three Caucasian university students were asked to make three-dimensional female faces appear as healthy and attractive as possible by changing faces along a continuum that portrays the facial adiposity change associated with a change in body mass index. Results showed that women preferred a significantly lower level of facial adiposity when judging attractiveness than when judging health, while men did not differentiate between the 'most attractive' and 'most healthy' looking level of facial adiposity. These findings are discussed in terms of the sociocultural portrayal of female body ideals and the preference for healthy individuals.

A prospective study on the impact of peer and parental pressure on body dissatisfaction in adolescent girls and boys

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

The protective role of general self-determination against ‘thin ideal’ media exposure on women’s body image and eating-related concerns

Women’s responses to ‘thin ideal’ media pending their level of general self-determination (GSD) were examined. High and low GSD women ( N = 99) viewed a ‘thin physique salient’ (TPS) video or a ‘thin physique non-salient’ (TPNS) video. Following exposure to the TPS video, perceptions of pressure from the media to be thin, body dissatisfaction, and concerns over quantity of food were greater for low but not high GSD women. However, high GSD women reported greater concerns over the quality of food they eat following exposure to the TPNS video. Prevention efforts aimed at enhancing GSD are discussed.

Social network media exposure and adolescent eating pathology in Fiji

BACKGROUND

Mass media exposure has been associated with an increased risk of eating pathology. It is unknown whether indirect media exposure--such as the proliferation of media exposure in an individual's social network--is also associated with eating disorders.

AIMS

To test hypotheses that both individual (direct) and social network (indirect) mass media exposures were associated with eating pathology in Fiji.

METHOD

We assessed several kinds of mass media exposure, media influence, cultural orientation and eating pathology by self-report among adolescent female ethnic Fijians (n=523). We fitted a series of multiple regression models of eating pathology, assessed by the Eating Disorder Examination Questionnaire (EDE-Q), in which mass media exposures, sociodemographic characteristics and body mass index were entered as predictors.

RESULTS

Both direct and indirect mass media exposures were associated with eating pathology in unadjusted analyses, whereas in adjusted analyses only social network media exposure was associated with eating pathology. This result was similar when eating pathology was operationalised as either a continuous or a categorical dependent variable (e.g. odds ratio OR=1.60, 95% CI 1.15-2.23 relating social network media exposure to upper-quartile EDE-Q scores). Subsequent analyses pointed to individual media influence as an important explanatory variable in this association.

CONCLUSIONS

Social network media exposure was associated with eating pathology in this Fijian study sample, independent of direct media exposure and other cultural exposures. Findings warrant further investigation of its health impact in other populations.

Examination of a sociocultural model of disordered eating among male and female adolescents

OBJECTIVES

The study tests a version of Stice's (1994) sociocultural model of disordered eating that was modified to incorporate social comparisons. Additionally, it examines how self-reported body-mass index and perceived weight status influence associations within the model.

METHOD

Questionnaires were administered in a state secondary school; the sample consisted of 250 female and 257 male adolescents aged 11-16 years.

RESULTS

The results supported the sociocultural model among both male and female adolescents. Perceived pressure to lose weight was directly associated with eating behaviour, as well as indirectly associated through social comparisons, internalization and body dissatisfaction. However, social comparisons were most strongly related to body dissatisfaction among adolescents who perceived themselves as overweight.

CONCLUSIONS

The findings indicate that models of eating disordered behaviour, developed for adolescent girls, are also appropriate for understanding this behaviour among male adolescents. The results suggest that social comparisons represent a useful addition to Stice's (1994) original model and a potentially fruitful target for interventions.

Primary and secondary control over eating behaviors

The relationships between subjective control, body image, and eating behaviors were examined within the framework of the Optimization in Primary and Secondary Control model (OPS model; Heckhausen, 1999). This model characterizes control as an adaptive and strategic process in which the target of control includes internal as well as external states, and in which the purpose is either to facilitate goal pursuit by engaging with the goal or managing the consequences of goal failure by disengaging from the goal. A convenience sample of 180 Australian women (age: M=26.49, SD=5.03) completed the Optimization of Primary and Secondary Control Scale (OPS scale Heckhausen, 1999), as well as measures of attitudinal and behavioral factors comprising Stice's (1994) dual-pathway model of bulimia. A series of path analyses revealed that the control strategies involved in goal engagement are directly associated with increased dietary restraint and purging, whereas the control strategies involved in goal disengagement are indirectly associated with these factors, and with negative affect, by way of reduced body dissatisfaction and reduced frequency of appearance comparisons. These results suggest that goal engagement strategies, which are typically adaptive in other contexts, are associated with potentially hazardous attitudes and behaviors in the context of the body. The results also suggest that an ability to disengage from body weight goals is associated with a reduced likelihood of developing disordered eating.

Having a personal weight goal that mismatches healthy weight recommendations increases the likelihood of using unhealthy behaviors among a representative population-based sample of adolescents

Free living populations adopt practices designed to maintain or influence their weight. These practices include at least two components: a personal weight goal and use of a variety of behaviors to reach this personal weight goal. Personal weight goals can either concur (match) or not concur (mismatch) with recommendations that a health professional might stipulate for achieving a healthy weight status. The variety of behaviors used to achieve a personal weight goal can be thought of as inherently healthy, unhealthy, or disordered. We examined associations between matched vs. mismatched personal weight goals and the frequency of use of different types of weight-related behaviors among adolescents. Measures included whether or not personal weight goals matched or mismatched aims that should be pursued given current weight status and self-reported frequency of use of behaviors from a representative population-based sample of adolescents (n=2, 346, 51% female; 93.3% complete data). Sex-specific multilevel logistic and ordinal regression analyses showed that pursuing a mismatched personal weight goal increases the likelihood of using unhealthy behaviors across sexes. This association is however not significant for healthy and disordered behaviors. We conclude that there is an association between pursuing a mismatched personal weight goal and the use of unhealthy behaviors but not with healthy or disordered behaviors.

Friendship group influences on body dissatisfaction and dieting among adolescent girls: a prospective study

PURPOSE

Although some studies among adolescent girls found that friends within friendship groups were rather similar on dieting and/or body image constructs, these studies were limited by their cross-sectional designs. The current prospective study is the first to examine friendship group influences on eating disorder risk factors, including body dissatisfaction, weight concerns, dietary restraint, and dieting in adolescent girls.

METHODS

Design was a two-wave prospective study with 1-year interval. Of 863 girls (mean age = 13.8, SD = .7), 344 were members of one of the 103 reciprocal friendship groups identified using social network analysis.

RESULTS

Reciprocal friends were similar with respect to body image and dieting constructs. However, initial friendship group levels of body dissatisfaction, weight concerns, dietary restraint, and dieting did not predict individual body image and dieting variables 1 year later.

CONCLUSIONS

The current findings attest to the significance of reciprocal friendship group correlates of eating disorder risk factors, but suggest that during early-to-mid-adolescence, levels of body image concerns and dieting within reciprocal friendship groups do not influence adolescents' own body image concerns and dieting over 1 year of time.

The effect of attachment insecurity in the development of eating disturbances across gender: the role of body dissatisfaction

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

Subtyping weight-preoccupied overweight/obese women along restraint and negative affect

Previous clustering analysis performed among samples of bulimic or binge eating women have consistently yielded two subtypes (Dietary and Dietary-Depressive). The present study verifies whether this clustering solution could be replicated among weight-preoccupied overweight/obese women and compares the different clusters on personality-, eating- and weight-related variables. Cluster analysis was performed along dietary restraint and negative affect among a sample of 156 overweight/obese weight-preoccupied women. Results failed to replicate the original two-cluster solution, rather evidencing a three-cluster solution (Dietary, Depressive, Low-Dietary/Low-Depressive). Also, dietary restraint did not appear to be a core feature for all weight-preoccupied overweight/obese women as it is for eating-disordered women since only one group presented dietary restraint. The presence of a pure Depressive group and a pure Dietary group showed that dietary restraint and negative affect may act independently among our sample. In term of clinical severity, the Dietary group, even in the absence of high negative affect, occupied an intermediate position between the Low-Dietary/Low-Depressive and the Depressive group, the most impaired one, in accordance with previous studies. It thus suggests that other factors beside negative affect can contribute to eating and psychological impairment among overweight/obese women.

Peer-facilitated cognitive dissonance versus healthy weight eating disorders prevention: A randomized comparison

Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N=106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months.

Examination of a sociocultural model of excessive exercise among male and female adolescents

There is substantial evidence that sociocultural pressures and body image disturbances can lead to disordered eating, yet few studies have examined their impact on excessive exercise. The study adapted a sociocultural model for disordered eating to predict excessive exercise using data from boys and girls in early adolescence (N=421). Perceived sociocultural pressures to lose weight and build muscle, body image disturbance and appearance investment were associated with a compulsive need to exercise. Adolescents' investment in appearance and body image disturbance fully mediated the relationship between sociocultural pressures and a compulsive need for exercise. There was no support for the meditational model in predicting adolescents' frequency or duration of exercise. Results support the sociocultural model as an explanatory model for excessive exercise, but suggest appearance investment and body image disturbance are important mediators of sociocultural pressures.

Desenvolvimento e validação preliminar da Escala Situacional de Satisfação Corporal - ESSC

O objetivo deste estudo foi desenvolver e validar um instrumento de satisfação corporal situacional numa amostra de estudantes universitários brasileiros. A escala inclui itens de avaliação de partes e do corpo como um todo. Análises fatoriais exploratórias revelaram uma estrutura com quatro fatores; "partes inferiores" (α=0,72), "satisfação e músculo" (α=0,82), "partes externas" (α=0,65) e "insatisfação e gordura" (α=0,82). Seus 28 itens obtiveram cargas fatoriais variando entre 0,32 e 0,82. Análises adicionais indicaram que a escala foi sensível a características da amostra, como Índice de Massa Corporal e gênero, corroborando a literatura atual da área.

Antecedents of eating disorders and muscle dysmorphia in a non-clinical sample

Muscle Dysmorphia (MD) has recently been conceptualized as the male form of Eating Disorders (ED); although, it is not currently classified as an ED. The current study compares etiological models of MD symptomatology and ED symptomatology. It was hypothesized that sociocultural influences on appearance (SIA) would predict body dissatisfaction (BD), and that this relationship would be mediated by self-esteem (SE) and perfectionism (P); that BD would predict negative affect (NA); and that NA would predict MD and ED symptomatology. Two-hundred-forty-seven female and 101 male college students at a midsouth university completed the study. All participants completed measures assessing each of the constructs, and multiple regression analyses were conducted to test each model's fit. In both models, most predictor paths were significant. These results suggest similarity in symptomatology and etiological models between ED and MD.

Attitudes Toward Cosmetic Surgery in Middle-Aged Women: Body Image, Aging Anxiety, and the Media

Our study investigated factors that influence attitudes toward cosmetic surgery in middle-aged women. A sample of 108 women, aged between 35 and 55 years, completed questionnaire measures of body dissatisfaction, appearance investment, aging anxiety, media exposure (television and magazine), and attitudes toward cosmetic surgery (delineated in terms of general attitudes, social motivations, and actual consideration). Body dissatisfaction, appearance investment, aging anxiety, and both media variables predicted some facet of attitudes toward cosmetic surgery. Specifically, appearance investment, aging anxiety, and television exposure were unique predictors of endorsement of social motivations for cosmetic surgery, whereas body dissatisfaction, appearance investment, and television exposure were unique predictors of actual consideration of cosmetic surgery. Regression analysis revealed that the effects of media on cosmetic surgery attitudes were primarily direct. We concluded that there are multiple influences on attitudes toward cosmetic surgery for women of middle age.

An examination of the interpersonal model of loss of control eating in children and adolescents

The interpersonal model of binge eating disorder proposes that social problems lead to negative affect which, in turn, precipitates binge eating episodes. However, no study to date has examined this model among youth who report loss of control (LOC) eating. Participants were 219 non-treatment-seeking children and adolescent volunteers, age 8-17 years (13.1 +/- 2.8 y; 50% female). Children's social problems were assessed by parent report. Youth completed self-report questionnaires of negative affect that assessed depressive symptoms and anxiety. Participants were interviewed to determine the presence or absence of LOC eating in the month prior to assessment. Structural equation modeling analyses found that social problems were positively related to LOC eating presence (p = .02). Negative affect mediated the relationship between social problems and LOC eating (95% CI Product = .00247, .01336). These preliminary results suggest that the interpersonal model of binge eating may describe one possible pathway for the development of LOC eating among non-treatment-seeking youth.

The sociocultural model of eating disorders in Mexican American women: behavioral acculturation and cognitive marginalization as moderators

White American cultural values of appearance are implicated in the development of body dissatisfaction. This study examined whether the relationships between awareness of White American appearance ideals, internalization of such ideals, and body dissatisfaction are moderated by behavioral acculturation and attitudinal marginalization in a sample of 94 Mexican American women. Results indicated that behavioral acculturation moderated the relationship between awareness and internalization and cognitive marginalization moderated the relationship between internalization and body dissatisfaction. Body size was positively correlated with body dissatisfaction and negatively correlated with behavioral acculturation. These findings have important implications for clinical practice and research with Mexican American women.

Longitudinal examination of maternal psychological control and adolescents' self-competence as predictors of bulimic symptoms among boys and girls

OBJECTIVE

Because bulimia nervosa is a problem among adolescents, it remains essential to examine its precursors. The specific etiologic chain investigated in this study is such that maternal psychological control first leads to adolescents' lowered self-competence, which in turn predicts bulimic symptoms.

METHOD

Self-report data were collected from 58 boys and 73 girls during sixth, seventh, and eighth grades. Participants reported on maternal psychological control, self-competence, and bulimic symptoms.

RESULTS

Using structural equation modeling, we tested our hypothesized longitudinal indirect effects model separately for boys and girls. Results indeed indicated that high maternal psychological control in sixth grade led to lowered adolescents' self-competence in seventh grade, which in turn predicted increased bulimic symptoms in eighth grade for both boys and girls.

DISCUSSION

This study uncovers one particular process wherein a psychologically controlling parenting style affects adolescents' development of bulimic symptoms, a finding that may be useful to researchers and clinicians.

Body dissatisfaction and the effects of perceptual exposure on body norms and ideals

OBJECTIVE

Body dissatisfaction is of high prevalence among women all over the Western world. It is often suggested that sociocultural processes are the main cause of such widespread dissatisfaction. Here, we consider how perceptual effects may influence ideas of body normality and body ideals.

METHOD

Women who varied on a measure of body dissatisfaction rated a range of bodies for how normal and ideal they looked. They were exposed to either thin or fat bodies, and then they rerated the bodies.

RESULTS

Women's perceptions of body normality and ideal were easily malleable by exposure. In addition, greater body dissatisfaction and internalization of the thin Western ideal were related to (i) a smaller most normal and ideal body, (ii) a greater discrepancy between the most normal and most ideal-rated body, and (iii) a reduced effect of exposure to fat bodies.

DISCUSSION

Reduced updating of perceptions of body normality and body ideals in response to experience may be one mechanism that maintains body dissatisfaction.

Preference for attractiveness and thinness in a partner: influence of internalization of the thin ideal and shape/weight dissatisfaction in heterosexual women, heterosexual men, lesbians, and gay men

This study assesses whether characteristics of one's own body image influences preferences of attractiveness in a partner. The role of gender and sexual orientation is also considered. Heterosexual women (n=67), lesbian women (n=73), heterosexual men (n=61) and gay men (n=82) participated in an internet survey assessing attitudes towards the body and preferences of attractiveness in a partner. Men in particular were found to prefer attractive partners, regardless of sexual orientation. Weight/shape dissatisfaction was found to be a negative predictor for heterosexual men and women. For gay men, preferences were better explained by internalization and weight/shape dissatisfaction. No such associations were found in the lesbian group. Levels of weight/shape dissatisfaction and internalization of socio-cultural slenderness ideals influence expectations of thinness and attractiveness in a partner with this effect being modified by gender and sexual orientation.

Strategies to Change Body Shape Among Men and Women Who Attend Fitness Centers

The current study examined the association between exercise behaviors, disordered eating, and other behaviors to change body shape among fitness center attendees. The participants were 520 adults (245 men, 275 women) who attended fitness centers. Data were gathered using an anonymous questionnaire. Women who attended fitness centers were generally trying to lose weight and improve fitness; men were generally trying to increase their muscles and improve their fitness level. Reasons for exercise predicted the nature of the body change strategies adopted by respondents. Regression analyses demonstrated that exercises performed by people who attend fitness centers are a reflection of whether or not they want to lose weight, increase muscle or improve fitness. All groups were equally likely to engage in health risk behaviors, but the specific nature of these behaviors varied by group. The implications of these findings for health-related messages among people who attend fitness centers are discussed.

Can we apply the dual-pathway model of overeating to a population of weight-preoccupied overweight women?

OBJECTIVE

The aim of the study is to verify the applicability of the dual-pathway model among weight-preoccupied overweight women and to document the restraint pathway, the negative affect pathway, and the possibility of a direct pathway from body dissatisfaction to overeating.

METHOD

Structural equations were performed to test the model on baseline data of 153 weight-preoccupied overweight women recruited to participate in a randomized trial.

RESULTS

Findings suggest that the model obtains satisfactory fit. Although the restraint pathway is partially supported, the negative affect pathway is confirmed. A third pathway linking directly body dissatisfaction to overeating is also evidenced.

DISCUSSION

The dual-pathway model of overeating seems to be representative of the reality of weight-preoccupied overweight women, which could be pointed as a population in need of clinical attention, particularly considering the dramatically increasing rates of obesity.

Sociocultural influences on body dissatisfaction and body change behaviors among Malaysian adolescents

Little research on body dissatisfaction and body change behaviors, and the sociocultural influences on them, has been undertaken in non-Western contexts. The current study investigated these variables and the relationships between them among a sample of 529 Malaysian high school students (103 Malays, 344 Chinese and 82 Indians), who completed a set of measures in classroom settings. Chinese girls were more dissatisfied with their bodies than Chinese boys, but no gender difference was found for Malay and Indian participants. Girls were more likely to engage in behaviors to lose weight, and boys were more likely to engage in behaviors to increase muscle. The influence of sociocultural factors on body dissatisfaction and body change behaviors was limited and varied across both sex and ethnicity. Findings are discussed in relation to Western research, and it is concluded that cultural nuances need to be considered when investigating these phenomena.
