Body Image Victimization Experiences and Disordered Eating Behaviors among Chinese Female Adolescents: The Role of Body Dissatisfaction and Depression

Disturbances in eating behavior and body image: The role of attachment, media internalization, and self-objectification

OBJECTIVE

Research has increasingly demonstrated the need to conceptualize the etiology of eating disorders beyond a sole focus on body image disturbance. Attachment patterns, media internalization, and self-objectification have been previously found to play a potential role in the development and maintenance of eating psychopathology.

METHOD

This study 1) examined the associations between eating behavior, body dissatisfaction, attachment, media internalization, and self-objectification, 2) evaluated media internalization and self-objectification as mediators of the relationship between insecure attachment patterns and both eating disorder symptomatology and body dissatisfaction, and 3) explored predictors of eating behavior in a sample of 252 Lebanese individuals between the ages of 18 and 25.

RESULTS

Eating disorder symptomatology was positively correlated with body dissatisfaction, insecure attachment patterns, media internalization, and self-objectification. Positive associations between attachment anxiety and avoidance and eating disorder symptomatology were mediated by media internalization and self-objectification. Positive associations between attachment anxiety and avoidance and body dissatisfaction were also mediated by media internalization and self-objectification. Body dissatisfaction, media internalization, attachment anxiety and avoidance, and self-objectification were identified as predictors of eating behavior, with media internalization accounting for the highest variance in eating behavior.

CONCLUSIONS

Insecure attachment, heightened susceptibility to internalizing unrealistic media portrayals, and an objectifying self-concept were found to be associated with eating disorder symptomatology and body image dissatisfaction. Findings were interpreted in light of suggested directions and considerations for the design of prevention and intervention programs.

Appearance-Related Victimization and Pubertal Asynchrony: Identifying Sex-Specific Vulnerabilities

Pubertal development is associated with many psychosocial and interpersonal changes, including a dramatic rise in appearance-related victimization. Yet, it is unclear what aspects of pubertal development provoke victimization along with which, and when, youth are at heightened risk. The present study seeks to address this gap by examining the effect of pubertal asynchrony (i.e., temporal variation in an individual's pubertal milestones) on appearance-related victimization and by determining whether associations between asynchrony and victimization differ by sex and pubertal status. In follow-up analyses, associations between pubertal asynchrony and different typologies of victimization were also assessed. Participants included 373 youth (Mage = 13.51 [1.62]; 40% girls, 60% boys; 61% White) drawn from an online sample. The results showed that more pubertal asynchrony was associated with more appearance-related victimization, especially for girls, but associations did not differ across pubertal status. Latent profile analyses of appearance-related victimization further suggested that asynchronous youth were more likely to be in profiles characterized by high appearance-related victimization as well as those characterized by high height-based victimization (boys only). The findings suggest that pubertal asynchrony contributes to appearance-related victimization in adolescence and highlights the need for targeted intervention efforts related to pubertal development and specific typologies of victimization.

Past body shaming experiences and food and alcohol disturbance in young adults: indirect effects via psychological distress

PURPOSE

This study investigated the associations between retrospective reports of body image victimization (i.e. body shaming) perpetrated by peers and by parents during childhood or adolescence, and food and alcohol disturbance (FAD) in young adulthood, considering the possible mediating role of psychological distress (i.e. subthreshold symptoms of anxiety and depression).

METHODS

The study involved 1624 young adults aged between 18 and 30 (69% women), who completed an online survey.

RESULTS

Our findings revealed that participants who reported more frequent body image victimization episodes during childhood and adolescence exhibited higher levels of psychological distress and, in turn, higher scores of FAD in young adulthood.

CONCLUSIONS

This result represents a novel contribution to understanding the psychological correlates of FAD in youths. Limitations and implications are discussed. Level of evidence Level V, descriptive study.

Depression and emotional eating in children and adolescents: A systematic review and meta-analysis

Major Depressive Disorder in youth is associated with obesity and adult cardiovascular disease (CVD) risk. Eating in response to emotions (emotional eating) is a potential contributing factor to this association. Although emotional eating is associated with Major Depressive Disorder in adults, findings in children and adolescents are mixed. This systematic review and meta-analysis aims to determine the association between depression and emotional eating in children and adolescents. Systematic searches were conducted in seven databases. Studies were included if the study population had a mean age of ≤18 years and assessed both depression and emotional eating using validated measures. The search generated 12,241 unique studies, of which 37 met inclusion criteria. Random-effects meta-analyses of study outcomes were performed. Thirty-seven studies (26,026 participants; mean age = 12.4 years, SD = 3.1) were included. The mean effect size was significant for both cross-sectional and longitudinal data (Hedges' g = 0.48, p < 0.0001; g = 0.37, p = 0.002, respectively), revealing a positive moderately strong association between depressive symptoms and emotional eating in youth. Among longitudinal studies, the association was stronger when depressive symptoms and emotional eating were assessed using child and adolescent self-report versus parent-report. No studies examined youth with a clinical diagnosis of depression. Meta-analyses revealed that depressive symptoms and emotional eating are positively associated in children and adolescents. However, further research in clinical samples is needed. Results raise the possibility for the importance of emotional eating in the link between depression and early CVD risk, though further examination is required to determine whether emotional eating is a potential treatment target to decrease CVD risk among adolescents with increased depression symptoms.

Athlete Body Image and Eating Disorders: A Systematic Review of Their Association and Influencing Factors

Body image and eating disorders pose significant challenges to the overall health of athletes. However, divergent findings exist regarding the potential association between athletes' body image and eating disorders. This systematic review aims to examine the relationship between these two variables and identify the modifiers of the association, such as gender, age, race, and exercise type. A search was conducted in five databases (Web of Science, PubMed, APA PsycINFO, ProQuest, and EBSCO), aiming to identify studies on athletes and involved body image and eating disorders in their conclusions. Ultimately, thirty-one studies were included for systematic evaluation. The results of the studies indicate that the relationship between athletes' body image and eating disorders is complex and inconclusive. In some types of sports, eating disorders can occur even when athletes are satisfied with their body image. Furthermore, female athletes, particularly young female athletes, and athletes involved in sports associated with leanness are more prone to eating disorders and body dissatisfaction. Due to limited resources in this type of research, there is a lack of comprehensive inclusivity across sports disciplines, genders, races, and levels of sports proficiency, which warrants further research.

Peer Appearance Teasing and Restrained Eating Among Chinese Adolescent Girls: A Mediation Model of Fear of Negative Appearance Evaluation and Body Surveillance

Restrained eating is becoming widespread recently. The present study aimed to examine whether peer appearance teasing was positively associated with restrained eating among Chinese adolescent girls and whether this association was mediated by fear of negative appearance evaluation (FNAE) and body surveillance. A sample of 720 Chinese adolescent girls completed questionnaires on peer appearance teasing, FNAE, body surveillance, and restrained eating. Peer appearance teasing was significantly and positively related to girls' restrained eating. FNAE mediated the relationship between peer appearance teasing and restrained eating. Furthermore, the association between peer appearance teasing and restrained eating was sequentially mediated by FNAE and body surveillance. The findings of this study provide new insights into the development of restrained eating among adolescent girls, and highlight peer appearance teasing and body surveillance as potential targets for intervention programs regarding body image concerns and eating disorders.

Eating Styles Profiles and Correlates in Chinese Postpartum Women: A Latent Profile Analysis

Postpartum women present a high risk of disordered eating behaviors, but the heterogeneity between groups was not identified. This cross-sectional study aimed to identify eating styles profiles in postpartum women and explore the correlates based on demographic characteristics and psychosocial factors. Questionnaires were administered to 507 Chinese postpartum women. Latent profile analysis (LPA) was conducted to identify eating styles profiles. Multinomial logistic regression was used to investigate the correlates of these profiles among postpartum women. The LPA identified three eating styles profiles: postpartum women with low emotional, external, and restrained eating (Profile 1, 6.9%); postpartum women with medium emotional, external, and restrained eating (Profile 2, 66.1%); and postpartum women with high emotional, external, and restrained eating (Profile 3, 27.0%). Compared to Profile 1, higher postpartum depression (PPD) and body mass index (BMI) were more likely to be associated with Profile 2 and Profile 3, whereas higher postpartum weight retention (PPWR) was more likely to be associated with Profile 1. Compared to Profile 2, higher PPD and BMI were more likely associated with Profile 3. Disordered eating behaviors in postpartum women with three eating styles were associated with BMI, PPD, and PPWR. This study can guide healthcare professionals in developing targeted interventions to improve maternal and child health globally.

The effect of desire to be liked and social appearance anxiety on aesthetic surgery acceptance in female nurses

BACKGROUND

A rapid increase has been observed in aesthetic surgery procedures in recent years and it has been determined that females have more aesthetic procedures. While different groups of female groups were taken as a sample in the studies, no study on female nurses was found. In this study, it is thought that psychological reasons such as stress, anxiety, desire to be liked and lack of self-confidence that lead women to plastic surgery will reduce the professional performance of nurses and this situation will create additional workload for other colleagues. Therefore, the aim of the study is to reveal the effect of desire to be liked and social appearance anxiety on the acceptance of female nurses to plastic surgery.

METHODS

The population of the cross-sectional study consisted of 243.565 nurses working in public, private and university hospitals in Turkey. A questionnaire form was used as a data collection tool in the study. In the first part of the form, there are statements aiming to reveal the socio-demographic characteristics, social media usage levels and aesthetic surgery experiences of nurses, and in the second part, there is a desire to be liked scale, social appearance anxiety scale and aesthetic surgery acceptance scale. The 1004 questionnaire forms collected as a result of the study were subjected to percentage, frequency, correlation and regression analysis.

RESULTS

41.2% of the nurses have had aesthetic procedures before and 68.4% of them want to have aesthetic procedures when there is an area they do not like in their body. A strong positive relationship was found between the desire to be liked, social appearance anxiety, and aesthetic surgery acceptance (r > 0.500, p < 0.01). Aesthetic surgery acceptance is affected by the desire to be liked and by social appearance anxiety.

CONCLUSION

In the study, it was determined that social appearance anxiety and the desire to be liked led female nurses to plastic surgery. According to the results of similar studies conducted in different groups, it may be recommended that awareness training be organized both in schools and through digital media about the consequences of unnecessary plastic surgery.

Adolescent-perceived parent-child negative body talk and disordered eating: Evidence for behavior-specific affective mediators

INTRODUCTION

This study examined the mediating role of general negative affect and body-specific negative affect between the association between negative body talk occurring within the mother-daughter relationship and restrained and disinhibited disordered eating.

METHODS

Adolescent girls (N = 100; Mage = 14.25; 49.5% White) completed self-report measures of general negative affect (depression and anxiety), body-specific negative affect (body dissatisfaction), and perceptions of the frequency that negative body talk occurred in interactions with their mother (initiated by the mother or daughter) as part of a cross-sectional study. While the same set of questionnaires was administered to both mothers and daughters, only the data reported by the daughters were analyzed and included in this study. Data were gathered in the Ann Arbor/Ypsilanti area of Michigan, USA, around the year 2015.

RESULTS

Path analysis showed that general negative affect, but not body-specific negative affect, mediated the association from mother-daughter negative body talk to disinhibited eating behaviors (emotional and external eating). Conversely, body-specific negative affect, but not general negative affect, mediated the association from negative body talk to restrained eating behaviors.

CONCLUSIONS

Our findings suggest there are distinct affective mechanisms that mediate the relationship between mother-daughter negative body talk and restrained versus disinhibited eating behavior. Future work should continue to explicate the role of general and body-related negative affect in different eating behaviors.

Harsh, unpredictable childhood environments are associated with inferior frontal gyrus connectivity and binge eating tendencies in late adolescents

Harsh, unpredictable childhood environments (HUCE) are associated with obesity older in life, but knowledge of how HUCE affect binge eating tendencies is lacking. Five hundred and one late adolescents aged 16-22 were recruited to finish resting state functional magnetic resonance imaging scan, behavioral measures including retrospective recall of childhood environmental harshness and unpredictability, binge eating tendencies and demographics. Three hundred and seventy-six of participants further completed the computerized visual probe task designed to evaluate attentional engagement towards high and low calorie food. As right inferior frontal gyrus (IFG) was the key nodes that related to both early life adversity and binge eating tendencies, it was treated as the interest region in the dynamic functional connectivity analyses. Results found that HUCE are associated with significant but modest decreases in connectivity of right inferior frontal gyrus (IFG)- bilateral medial frontal gyrus, right IFG - bilateral inferior parietal lobule (IPL), and right IFG - left superior frontal gyrus connectivity, as well as attentional engagement to high-calorie food and binge eating tendencies. A machine-learning method named linear support vector regression (SVR) and leave one out cross-validation (LOOCV) procedure used to examine the robustness of the brain-behavior relationship further confirm the findings. Mediation analyses suggested that right IFG - left IPL connectivity mediates the association of HUCE and binge eating tendencies. Findings suggest right IFG - left IPL connectivity may serve as a crucial neurobiological underpinning of HUCE to regulate binge eating behaviors. As such, these results contribute to a novel perspective and hypotheses in elucidating developmental neuro-mechanisms related to binge eating.

Variables that explain disordered eating behaviors among women: the mediating role of body dissatisfaction

PURPOSE

To analyze the role of body dissatisfaction in the relationships of sociocultural influences, depression, and anxiety with disordered eating behaviors (DEB) in a sample of female Mexican university students.

METHODS

A nonrandom sample of 526 female Mexican university students aged 18 to 25 years completed the Questionnaire of Influence on the Aesthetic Model of Body Shape (CIMEC-26), the Hospital Anxiety and Depression Scale (HADS), the Body Shape Questionnaire (BSQ-8D) and the Eating Attitudes Test (EAT-26).

RESULTS

Through the mean model (χ2/df (5, n = 526) = 7.298, p = .199; NFI = .996; CFI = .999; RMSEA = .030; SRMR = .011), body dissatisfaction was found to mediate the relationships of influence of advertising, influence of social models and anxiety with DEB (restrictive dieting and bulimia). The variable with the most direct effect on restrictive dieting and bulimia was the influence of advertising. Body dissatisfaction partially mediated this relationship, as the influence of advertising had a significant direct effect on restrictive dieting and bulimia. The final model of direct and indirect effects explained 43% and 22% of the variance in restrictive dieting and bulimia, respectively.

CONCLUSION

The present study showed that body dissatisfaction partially mediated the relationships between influence of advertising, influence of social models, and anxiety with DEB among women. Thus, these variables should be taken into account in prevention and intervention programs targeting BED.

The effect of gender in binge eating behavior in Chinese culture: the serial mediation model of body dissatisfaction and self-acceptance

Introduction

The gender difference of binge eating behavior been highlighted by previous studies. However, psychological mechanisms underlying the gender difference of binge eating behavior remain unclear. This study addressed this issue from a sociocultural perspective.

Methods

Firstly, we investigated the mediation effect of body dissatisfaction on the gender difference of binge eating behavior. Secondly, we examine the serial mediating role of body dissatisfaction and self-acceptance in gender differences of binge eating behavior. Here, we analyzed data from 703 Chinese university students using SPSS 26.0 and SPSS PROCESS.

Results

In Chinese culture, body dissatisfaction and self-acceptance independently or through a serial way mediate the gender differences in binge eating behaviors.

Discussion

We discussed the implications and limitations of the present study.

Role of peer support on the cycle of weight teasing, psychological distress and disordered eating in Taiwanese adolescents: A moderated mediation analysis

BACKGROUND

Several studies have reported the beneficial role of social support on adolescent health. However, few studies have explored the role of peer support on the cycle of weight teasing, psychological distress, and disordered eating.

METHODS

A total of 689 adolescents aged between 13 and 16 years recruited from 37 classes in three middle schools in New Taipei City from March to June 2019 were included for analysis. Path analysis was performed using Hayes' PROCESS module.

RESULTS

The study found that weight teasing is directly and indirectly associated with disordered eating through psychological distress. Peer support plays a role in moderating the relationship between weight teasing and psychological distress; however, it is not significantly associated with decreased risk of disordered eating among adolescents experiencing weight teasing.

CONCLUSION

While peer support can be used against the adverse effects of weight teasing, it is not the absolute solution, and additional interventions are warranted.

Social support and overeating in young women: The role of altering functional network connectivity patterns and negative emotions

Research suggests that social support has a protective effect on emotional health and emotionally induced overeating. Women are especially more sensitive to benefits from social support when facing eating problems. Although it has been demonstrated that social support can affect the neural processes of emotion regulation and reward perception, it is unclear how social support alters synergistic patterns in large-scale brain networks associated with negative emotions and overeating. We used a large sample of young women aged 17-22 years (N = 360) to examine how social support influences the synchrony of five intrinsic networks (executive control network [ECN], default mode network, salience network [SN], basal ganglia network, and precuneus network [PN]) and how these networks influence negative affect and overeating. Additionally, we explored these analyses in another sample of males (N = 136). After statistically controlling for differences in age and head movement, we observed significant associations of higher levels of social support with increased intra- and inter-network functional synchrony, particularly for ECN-centered network connectivity. Subsequent chain-mediated analyses showed that social support predicted overeating through the ECN-SN and ECN-PN network connectivity and negative emotions. However, these results were not found in men. These findings suggest that social support influences the synergistic patterns within and between intrinsic networks related to inhibitory control, emotion salience, self-referential thinking, and reward sensitivity. Furthermore, they reveal that social support and its neural markers may play a key role in young women's emotional health and eating behavior.

A feminist approach to eating disorders in China: a qualitative study

BACKGROUND

As women continue to be more at risk from eating disorders, gender has often been a focus of concern in transcultural research. Yet feminist, qualitative studies which prioritize the voices of women/girls remain rare within transcultural work suggesting the need for greater interaction between these fields. This article seeks to contribute to the exploration of the applicability of feminist paradigmslargely developed in the West-to experiences of EDs in non-western contexts.

METHODS

This article draws on semi-structured interviews with 12 women from urban China with self-reported experience of Bulimia Nervosa (BN) and binge eating disorder (BED) in order to explore the complex ways in which gender may be implicated within eating/body distress from a transcultural point of view. The data is analysed through Reflexive Thematic Analysis.

RESULTS

The data analysis suggested two broad themes: (1) Chinese versus Western codes for judging female appearance: from surveillance to liberation (2) Discipline, appetite and control: the gendered/cultural meanings of binging and purging. In terms of the first theme, many participants had spent time in the West which was understood as a less regulated context in terms of gendered body surveillance and eating. Complicating existing assumptions about the 'Westernisation' thesis, different communication codes and peer interactions across Chinese and Western contexts played a central role in how participants experienced their bodies. In the second theme, binging and purging emerged as a way to manage a number of contradictions surrounding Chinese femininity, including respecting familial food cultures, contradictory discourses on female 'appetite', and the need to display a female body which signified cultural imperatives of self-restraint and discipline.

CONCLUSIONS

The data emphasises the importance of examining the culturally specific meanings of eating problems and their gendered contexts, whilst there is clearly much that echoes Western feminist work on Western samples. Although limited, the study crucially points to the importance of examining how ED subcategories other than AN can be explored from a transcultural and feminist point of view.

Altered effective connectivity between reward and inhibitory control networks in people with binge eating episodes: A spectral dynamic causal modeling study

BACKGROUND

Converging evidence points to the crucial role of brain connectivity involved in aberrant behavioral control and reward reactivity in the onset and maintenance of binge eating. However, the directional interaction pattern between brain's reward and inhibitory control systems in people with binge eating episodes is largely unknown.

METHODS

Resting-state fMRI data were collected from 36 adults with binge eating episodes (age: 19.05 ± 0.90) and 36 well-matched controls (age: 18.88 ± 0.78). We applied spectral dynamic causal modeling approach to estimate effective connectivity of the executive control network (ECN) and reward network (RN) with 15 predefined regions of interest, and investigate the between-group differences in directional connectivity.

RESULTS

Compared with controls, the positive connections within the ECN were significantly strengthened in individuals with binge eating episodes, while the negative connections from the ECN to RN and from the RN to ECN were significantly weakened. In adults with binge eating episodes, the RN→ECN connectivity was positively related to binge frequency even controlling for age, sex, and body mass index.

CONCLUSION

This study represents an important first step in addressing the role of directional integration between reward and inhibitory control networks in binge eating, and provides novel evidence that the ability of people with binge eating episodes to maintain a balance between inhibitory control and reward reactivity is decreased, as reflected by diminished bidirectional negative effects of prefrontal-subcortical circuitry at rest.

Negative family body talk and negative emotional eating among Chinese adolescent girls and young adult women: The role of body dissatisfaction and feminism consciousness

Negative emotional eating has been increasingly a prominent disordered eating and public health problem among young women, especially during COVID-19. Although previous studies have attempted to explain the relationship between body talk and negative emotional eating, limited studies focused on examining the potential mechanisms, especially the potential protective mechanism. Thus, the current study aimed to examine the relationship between negative family body talk (NFBT) and negative emotional eating, as well as its underlying mechanism - the mediating role of body dissatisfaction (BDIS) and the moderating role of feminism consciousness (FC). A cross-sectional study was employed among a sample of Chinese girls and young women (n = 813, M_age = 19.4 years) from a junior college in central China. Participants completed surveys assessing NFBT (Adapted Body Talk Scale), BDIS (Body Image State Scale), negative emotional eating (Dutch Eating Behavior Questionnaire), and FC (Synthesis Subscale from Feminist Identity Composite). A moderated mediation analysis was conducted. The results showed that: (1) after controlling for age and BMI, NFBT was positively associated with negative emotional eating, and BDIS could significantly mediate this relationship (mediating effect = 0.03, 95% CI [0.02, 0.06]); (2) FC significantly moderated both the direct relationship between NFBT and negative emotional eating and the relationship between NFBT and BDIS. Specifically, these two associations were not significant for participants with higher FC (+1SD above average). This study deepens our understanding of the relationship between NFBT and negative emotional eating, as well as the protective role of FC. If future studies demonstrate causal relationships, this evidence could point to a need for programs to prevent negative emotional eating in young women by increasing their level of feminism consciousness.

Comparative efficacy of remotely delivered mindfulness-based eating awareness training versus behavioral-weight loss counseling during COVID-19

Introduction

Dysregulated eating (emotional eating, cue-elicited eating, and dietary restraint and restriction) has been linked to being overweight or obese. The present investigation used a random controlled trial (RCT) to test the differential efficacy of remotely delivered Mindfulness-Based Eating Awareness Training (MB-EAT) and Behavioral Weight Loss (BWL) counseling.

Methods

The sample was recruited through advertisements that offered help to people "with problems controlling their eating" or "interested in improving their relationship with food" (n = 135).

Results

Retention was low in both groups (42%), but not dissimilar to retention rates reported in related clinical trials delivered "in person." Among the participants who completed treatment, we found no between-group differences in any of the treatment outcomes, but participants in both groups experienced significant increases in eating-related mindfulness [Mindful Eating Questionnaire (MEQ) and awareness [Multidimensional Assessment of Interoceptive Awareness (MAIA), and significant decreases in unhealthy eating patterns [Dutch Eating Behavior Questionnaire (DEBQ); Binge Eating Scale (BES), and weight over the course of treatment. Participants in both groups also experienced increases in self-reported depression and anxiety symptoms [Hospital Anxiety and Depression Scale (HADS)], although these increases likely reflected normative changes observed in the population at large during COVID-19.

Discussion

Overall, the results suggest that dysregulated eating and weight loss intervention delivered remotely via teleconference can be effective.

The Association of Eating Behaviour with Physical Activity and Screen Time among Adolescents in the Klang Valley, Malaysia: A Cross-Sectional Study

Over the last few decades, the time adolescents spend using electronic devices has increased significantly. The aim of this study was to evaluate the impact of screen time and physical activity on eating behaviour in adolescents. This study used the Physical Activity Questionnaire for Adolescents (PAQ-A) Malay version and the Dutch Eating Behaviour Questionnaire (DEBQ) Malay version methods with secondary students around the Klang Valley. The sampling technique used was purposive sampling. With parents' consent, an online survey was conducted among adolescent school children aged between 13 and 17 years during the COVID-19 pandemic in the Klang Valley, Malaysia. There were 372 respondents participating in this study. The results showed that 99.4% of them had more than 4 h screen time a day, and that 38.5% have more than three devices at home. Moreover, there was a significant mean difference in screen time for console games without a handheld device between male and female adolescents (p < 0.05). There was also a significant mean difference in the emotional, restricted and external eating behaviour scores between male and female adolescents (p < 0.001). There was a significant relationship between physical activity and the time duration spent on a television, telephone and laptop during weekends (p < 0.05). There was a significant relationship between eating behaviour and time spent watching television and using laptops during weekends (p < 0.05). Based on the moderation model, gender as a moderator variable indicated that there was a significant relationship between screen time and interaction screen time and gender with emotional eating (p < 0.001). Female adolescents had a stronger relationship between screen time and emotional eating compared to male adolescents (p < 0.05). Meanwhile, for physical activity level as a moderator variable, the results showed that there was a significant interaction between screen time and physical activity for emotional eating behaviour (p < 0.05). In conclusion, this study indicates that screen time was higher among female adolescents and significantly related to emotional eating behaviour. Therefore, the educational sector should emphasise the motivation of adolescents to engage in physical activity, reduce their screen time and eat healthy foods such as fruits and vegetables.

Differential pathways to disordered eating for immigrant and native adolescents in Taiwan

BACKGROUND

Few studies have investigated disparities in disordered eating between new immigrant and native adolescents in Taiwan. This study examines the differential pathways to disordered eating in these two populations.

METHODS

This cross-sectional study analyzed data collected from March to June 2019. In total, 729 adolescents aged between 13 and 16 years recruited from 37 classes in 3 middle schools in New Taipei City were included in the final analysis. Standardized assessment tools measured disordered eating (EAT-26) and psychological distress (BSRS-5). Generalized structural equation modeling was used to conduct the path analysis.

RESULTS

The prevalence of disordered eating was significantly higher in immigrant adolescents than in their native counterparts. Multipath models indicated that weight-teasing driven by overweight and obese status and weight overestimation could lead to disordered eating through psychological distress; however, the pathways differed for the two groups studied. Family weigh-teasing indirectly leads to disordered eating through psychological distress for native adolescents; by contrast, for immigrant adolescents, friend weigh-teasing indirectly leads to disordered eating through psychological distress. Additionally, weight overestimation directly leads to disordered eating and indirectly through psychological distress to disordered eating for immigrant adolescents.

CONCLUSION

This study offers a plausible explanation of the differences in the paths to disordered eating between immigrant and native adolescents in Taiwan, which was not reported previously. The study urges the need for school-based prevention programs to improve immigrant students' mental health.

The Mediating Role of Eating Attitudes in Sociocultural Attitudes toward the Body in Predicting Obligatory Exercise among Young People: A Polish and Chinese Comparison

The main aims of this study were to determine which sociocultural predictors of obligatory exercise are universal for young men or women and which are specific to particular cultural conditions (Polish or Chinese culture) and to examine the mediating role of eating attitudes. A cross-sectional study was conducted among Poles (n = 259) and Chinese (n = 208) aged 18 to 30. Descriptive and comparative statistics, Spearman's rho, and multiple regression analysis were used. The main analyses showed that Internalization-Athlete was a common positive direct predictor of obligatory exercise among young Polish and Chinese women; Information and Internalization-Athlete were only specific direct positive predictors of obligatory exercise in young Chinese men; some variables in eating attitudes mediated the development of obligatory exercise in young Polish and Chinese men and women and indicated that there were cross-cultural differences. In understanding obligatory exercise among young people, attention should be paid to their sociocultural attitudes toward the body and eating, and cultural and gender differences need to be considered.

Associations of harsh, unpredictable environment, amygdala connectivity and overeating for children

OBJECTIVE

In harsh and unpredictable environments, individuals tend to engage in activities that yield immediate rewards as delayed benefits can be unavailable. Substantial evidence suggests that a harsh and unpredictable childhood environment is associated with overeating. However, the neuromechanisms underlying this association remain unclear. This study aimed to investigate amygdala connectivity in relation to environmental harshness and unpredictability (EHU) from an evolutionary perspective and examine their relationship with overeating in children.

METHODS

Eighty-five children aged 8 to 12 years were scanned using a magnetic resonance imaging machine to assess resting-state functional connectivity (RSFC) of the two subregions of the amygdala (i.e., centromedial amygdala [CMA]; basolateral amygdala [BLA]). Self-reports of EHU and parental reports of overeating, including food responsiveness and enjoyment of food, were obtained cross-sectionally. Furthermore, findings indicated that children completed high- and low-calorie food portion choice tasks in the absence of hunger at 12 months of follow-up.

RESULTS

EHU was positively associated with parental reports of overeating, including food responsiveness and enjoyment, as well as children's selection of high-calorie food portion sizes. Moreover, static RSFC analyses revealed that EHU was negatively associated with bilateral BLA-left inferior frontal gyrus (IFG) connectivity, while dynamic RSFC analyses found that EHU was negatively associated with right CMA, left inferior parietal lobule, and right CMA-right precuneus connectivity. Particularly, the left BLA-left IFG connectivity mediated the association between EHU and parental reports of food responsiveness.

CONCLUSION

EHU was negatively associated with amygdala connectivity, which is implicated in the intrinsic processing of emotional regulation. Furthermore, deficits in emotional regulation resulted in increased energy intake. These insights provide a new perspective for understanding the developmental neuromechanisms underlying obesity.

The association between social media addiction and orthorexia nervosa, eating attitudes, and body image among adolescents

AIM

This study was planned to determine the relationship between social media addiction and orthorexia nervosa (ON), eating attitude and body image among adolescents.

METHOD

This cross-sectional study was conducted with 1232 high school-going adolescents. Data were collected using the Social Media Addiction Scale for Adolescents, Eating Attitude Test-26 (EAT-26), Body Image Scale (BIS) and ORTO-11 questionnaire.

RESULTS

Social media addiction levels were higher in girls than in boys (p < 0.05). Multiple linear regression analysis showed that a better body image was associated with lower social media addiction scores (β =  - 0.268, p < 0.001). Social media addiction was significantly associated with a greater risk of eating behavior disorders (OR: 1.07, 95% Cl: 1.04-1.10) and ON tendency (OR: 1.02, 95% Cl = 1.00-1.04). Adolescents who stated that they always or often read nutrition-related posts on social media had an increased likelihood of eating behavior disorder risk (OR: 6.77, 95% CI: 3.84-11.94) and ON tendency (OR: 5.49, 95% CI: 3.39-8.88).

CONCLUSION

This study demonstrated that social media addiction was associated with a higher eating behavior disorder risk, ON tendency and lower body image. Moreover, frequent reading of posts about nutrition on social media was positively associated with ON tendency and eating behavior risk. These results highlight that adolescents should be educated about social media use and its content to minimize the negative effects of constant exposure to unrealistic body images and nutrition-related misinformation and reduce the risk of eating disorders and ON among adolescents.

Psychometric properties of the Chinese version of the Female Muscularity Scale among Chinese young women

PURPOSE

The Female Muscularity Scale (FMS) was specifically developed for assessing drive for muscularity in women. The current study aimed to translate the FMS into Chinese (FMS-C) and examine its psychometric properties among Chinese young women.

METHODS

Based on standard procedures, the FMS was translated into Chinese. By using the psych and lavaan packages on R version 4.0.3, the current study examined the factor structure, reliability, and convergent and incremental validity of the FMS-C with a sample of 517 Chinese women college students ([Formula: see text]= 18.86 years).

RESULTS

Results showed a 2-factor structure including attitudes and behaviors of the FMS-C. The internal consistency reliability (Cronbach's α) was .91 for the total FMS-C scale and .89 and .88 for the Attitudes and Behaviors subscales, respectively. Results also revealed evidence for good convergent and incremental validity of the FMS-C.

CONCLUSION

Findings suggest that the FMS-C can be a useful tool to measure both attitudes and behaviors underlying drive for muscularity and muscle tone concerns among Chinese young women.

Association between high levels of body-esteem and increased degree of midcingulate cortex global connectivity: A resting-state fMRI study

Multiple neuroimaging studies have examined the neural underpinnings of body image disturbances in patients with eating disorders. However, key brain regions related to body image, such as body-esteem (BE), among healthy individuals are understudied. Given the extremely crucial role of BE in eating behaviors and physical and mental health, the current study conducted data-driven analysis and characterized the neurobiological correlates of BE with the network properties of the resting brain using the voxel-wise degree centrality (DC) measures of resting-state functional magnetic resonance imaging (rs-fMRI) data and seed-based resting-state functional connectivity (RSFC). A total of 694 healthy young adults (females = 474, mean age = 18.38 years, range = 17-22) underwent rs-fMRI, and completed the Body-Esteem Scale for Adolescents and Adults, the Eating Disorder Diagnosis Scale, and the Restraint Scale. After correcting for differences in age, gender, body mass index, and head motion, whole-brain correlation analyses revealed that a high level of BE was associated with increased DC within the right midcingulate cortex (MCC) and subsequent high levels of MCC-based RSFC strengths. Furthermore, MCC connectivity patterns related to BE were inversely associated with disordered eating behaviors. These findings suggest that adaptive cognitive and emotional regulation (i.e., self-evaluation and emotion based on body image) may explain the potential relationship between MCC connectivity patterns and BE to a certain extent. As such, future studies should investigate these interesting possibilities.

Body and mirror paradox of nursing students: Vicious cycle of popular diets

PURPOSE

To examine the popular dietary habits of nursing students and associated factors.

DESIGN AND METHODS

A mixed study with quantitative and qualitative dimensions. Following the evaluation of quantitative data, interviews were conducted with 12 students, and data were analyzed by content analysis.

FINDINGS

The two main themes created were my mirror and the mirror of society as a vicious cycle. The reasons for being on a popular diet were determined to be the expectation of rapid weight loss, negative emotions, and body and beauty perception of society.

PRACTICE IMPLICATIONS

It is concluded that students are in a vicious cycle of popular diets depending on different factors and that professional educator nurses have important duties in breaking this cycle.

Body Dissatisfaction and Disordered Eating Behaviors: The Mediation Role of Smartphone Addiction and Depression

This study aimed to determine whether smartphone addiction and depression sequentially mediate the relationship between body dissatisfaction and disordered eating behaviors (e.g., restrained eating, emotional eating and external eating). A total of 5986 participants (54.1% females, average age = 19.8 years, age range = 17–32) completed the Satisfaction and Dissatisfaction with Body Parts Scale, the Three-Factor Eating Questionnaire, the Smartphone Addiction Scale and the Patient Health Questionnaire-9. Mediational analysis showed that, after controlling for age, sex and body mass index, body dissatisfaction was related to disordered eating behaviors through (a) the mediating effect of smartphone addiction, (b) the mediating effect of depression, and (c) the serial mediating effect of smartphone addiction and depression. In conclusion, our study showed for the first time that smartphone addiction and depression can be sequential mediator variables in the association between body dissatisfaction and disordered eating. However, this study is a cross-sectional study; future longitudinal studies could further test the causal associations between these study variables.

Testing links between unfavorable living conditions, fast life-history strategy adoption, and overeating: a four-wave longitudinal study

Although overeating increases risk for chronic illness and premature mortality, evolutionary life-history theorists posit that such behaviors arise as a potential outcome of using fast life-history strategies to function in environments that are harsh or unpredictable. To test this premise, we examined links between harsh, unpredictable living conditions (HULC), the adoption of fast life-history (LH) strategies, and overeating among early adolescents using a four-wave longitudinal design. Participants were 2547 Chinese adolescents (1202 girls, 1345 boys) who completed baseline questionnaires assessing experiences of HULC, preferences for use of fast LH strategies, and overeating. Measures were re-administered in follow-ups 7, 13, and 20 months later. Analyses indicated HULC predicted increased use of fast LH strategies within each gender. However, fast LH strategy adoption contributed to increases in overeating only among girls. Findings supported specific tenets of life-history theory and underscored gender as an important consideration in understanding links between living conditions, the adoption of fast LH strategies, and risk for overeating. Interventions focused on reducing poverty and increasing stable, nurturing family, and community environments may aid in reducing overeating and obesity for adolescents.

Gender and Cultural Differences in the Relationships between Self-Esteem Contingency, Body Talk, and Body Esteem

This study analyzed the positive and negative body talk of male and female adolescents cross-culturally with an emphasis on the role of appearance-contingent and others' approval-contingent self-worth. A cross-national survey in Austria, Belgium, Spain, and South Korea among 12- to 16-year-olds (982 female and 993 male) found that (1) positive body talk was positively related and negative body talk was negatively related to body esteem; (2) appearance contingency was positively related to negative body talk; (3) appearance contingency increased positive body talk among girls (except Korean girls); and (4) contingency on other's approval increased positive body talk among boys in all four countries. Overall, gender differences were more prominent than cultural differences and positive body talk was instrumental in promoting adolescents' body esteem.
