Incorporating social media and muscular ideal internalization into the tripartite influence model of body image: Towards a modern understanding of adolescent girls' body dissatisfaction

Influence of TikTok on Body Satisfaction Among Generation Z in Indonesia: Mixed Methods Approach

BACKGROUND

As social media platforms gain popularity, their usage is increasingly associated with cyberbullying and body shaming, causing devastating effects.

OBJECTIVE

This study aims to investigate the impact of social media on Generation Z users' body image satisfaction. More specifically, it examines the impact of TikTok on body image satisfaction among TikTok users aged between 17 years and 26 years in Indonesia.

METHODS

The methodology used mixed-method approaches. Quantitative data were obtained from 507 responses to a questionnaire and analyzed using covariance-based structural equation modeling. Qualitative data were obtained from the interviews of 32 respondents and analyzed through content analysis.

RESULTS

This study reveals that upward appearance comparison is influenced by video-based activity and appearance motivation. Conversely, thin-ideal internalization is influenced by appearance motivation and social media literacy. Upward appearance comparisons and thin-ideal internalization comparisons detrimentally impact users' body image satisfaction.

CONCLUSIONS

The results of this study are expected to provide valuable insights for social media providers, regulators, and educators in their endeavors to establish a positive and healthy social media environment for users.

Risks and benefits of social media trends: The influence of "fitspiration", "body positivity", and text-based "body neutrality" on body dissatisfaction and affect in women with and without eating disorders

This online experimental study investigates the effects of the social media trends "fitspiration" (images of thin-muscular women promoting health and fitness), "body positivity" (images of larger female bodies motivating women to love their bodies), and "body neutrality" (illustrations encouraging women to appreciate the body's functions) on body dissatisfaction and affect in women with and without eating disorders (ED). Women with (n = 172) and women without ED (n = 210) were randomly assigned to the conditions "fitspiration", "body positivity", and text-based "body neutrality", each comprising the presentation of 30 Instagram posts. Before and after viewing the posts, participants answered state questionnaires on body dissatisfaction and affect. The results revealed that body dissatisfaction increased after viewing "fitspiration" images and decreased after viewing "body positivity" and text-based "body neutrality" posts. Positive affect decreased following exposure to "fitspiration" and text-based "body neutrality" but remained unchanged following "body positivity". Negative affect decreased following "body positivity" and text-based "body neutrality" content but did not change following exposure to "fitspiration". There was no differential effect on women with versus without ED. This study demonstrates harmful effects of "fitspiration" on body image and affect, indicating the need for prevention programs for both women with and without ED.

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.

The Pattern of Physique Preferences on Gay Dating App "Blued" in China: A Multiple Group Latent Class Analysis

Previous studies have indicated homogamy in partner preferences among gay and bisexual men. Individuals on Blued (the most popular gay dating app in China) could identify their body type and preferred physiques according to six categories: monkey (thin gay men), average, muscularity, bear (heavy and hairy gay men), baboon (smaller than bears), and pig (plumper than bears). This study examined patterns of physique preferences across body types as well as sexual self-labels (tops, bottoms, versatiles, and others). In total, 188,716 Blued profiles (Mage = 31.1, SD = 7.1) were obtained. Multiple group latent class analysis was used to examine the patterns of physique preferences across the body type groups. The results revealed seven classes of physique preference. The four common physique preferences shared by all body type groups were "like averages," "like monkeys," "like muscularity," and "like bears." Individuals with a monkey or average body type exhibited a specific pattern of physique preference: "dislike bears." The two physique preferences specific to gay bear men were "like averages and muscularity," and "dislike monkeys." The highest preference for each physique was observed among individuals of the same body type. Furthermore, tops were more likely to have a muscular body and prefer a monkey physique, whereas bottoms were more likely to have a monkey body and prefer a muscular physique. These findings indicate body type-specific physique preferences based on an individual's own body type and sexual self-label identification, thus partially supporting the concept of homogamy in the physique preferences of gay men.

Development and psychometric assessment of the Sociocultural Influences on Exercise Behaviours in Adolescents Questionnaire

OBJECTIVES

This research aimed to construct and psychometrically test a measure of multiple sociocultural dimensions (i.e. family, peers, media) theoretically associated with exercise behaviours/attitudes in adolescents; the Sociocultural Influences on Exercise Behaviours in Adolescents Questionnaire (SIEBAQ).

METHODS AND MEASUREMENT

Part 1 of this study focused on measure construction and psychometric testing, involving item generation and exploratory factor analysis (EFA) to refine the item pool, with 905 adolescents (Mage 13.66 years (SD = 0.94); girls = 442). Part 2 sought to explore the convergent validity of the SIEBAQ (n = 846; n = 414 girls).

RESULTS

EFA resulted in a 47-item measure with a nine-factor structure (including social media modelling, parent exercise expectations, peer co-participation; α = 0.72-0.92). Correlations revealed weak-moderate significant relationships between the SIEBAQ and related constructs (e.g. compulsive exercise, sociocultural attitudes towards appearance). Regression analyses with the SIEBAQ identified social media modelling of exercise as a significant predictor of compulsive exercise in boys and girls. Proving exercise ability to significant others also significantly predicted compulsive exercise outcomes.

CONCLUSION

This newly developed measure holds promise. Further psychometric testing and validation of the SIEBAQ is the recommended next step to confirm the measure's nine-factor structure identified through EFA.

A Qualitative Model of Weight Cycling

Weight cycling is a likely consequence of striving to lose weight after internalizing body image ideals, making upward social comparisons, and experiencing weight stigma. Despite weight cycling's potential physical and psychological consequences, the interplay of weight cycling, social pressures, and experienced and internalized stigma have not been qualitatively explored. Thus, through in-depth interviews of 36 weight-cycling adults, this study sought to understand how people negotiate weight cycling. Interviews informed the development of a qualitative model of weight cycling, which was derived from a theory-neutral inductive analysis. The model's stages included entering the cycle, undergoing the cycle, and challenging the cycle. Participants were triggered to enter the cycle due to weight stigma caused by social pressures. Within the cycle, interviewees internalized weight stigma and engaged in disordered weight management behaviors. Some participants challenged the cycle by becoming more self-aware and mitigating their toxic dieting behaviors. However, it was very difficult, if not impossible, for many to fully exit weight cycling and the restraints of previous weight management thinking and patterns. Our investigation underscores the seriousness of weight cycling and suggests ways to combat weight cycling on both macro and individual levels. It may also be useful to consider weight cycling as disordered eating in hopes of shifting society's dangerous focus on rapid weight loss.

An exploration of having social media influencers deliver a first-line digital intervention to improve body image among adolescent girls: A qualitative study

Social media influencers are popular among adolescents and could offer a unique way to reach young people at scale with body image interventions. This study explored girls' and influencers' views on having influencers deliver body image interventions through vlogs (video blogs) and to gain insight into their preferred format, content, and views on factors that encourage engagement with vlogs. Twenty-one UK based participants were recruited. Three online focus groups were conducted with adolescent girls (n = 16) aged 14-18 years and one with influencers (n = 5) aged 24-33 years, who had a collective following of over 1.5 million subscribers across social media platforms. Data were analysed using reflexive thematic analysis and four themes were generated: Choosing an influencer whose messages and core values are aligned with the topic of body image; the importance of influencer authenticity and personal experience; collaborating on content creation with mental health professionals; and the need for long-form (i.e., 10-20 min) content to address serious topics. Findings suggest having influencers deliver body image interventions to young people could be a useful approach. Results highlight the need to engage with end users from the outset of intervention development to increase the likelihood of intervention effectiveness and engagement.

Is my body better than yours? Validation of the German version of the Upward and Downward Physical Appearance Comparison Scales in individuals with and without eating disorders

Introduction

This study examines the psychometric properties of a German version of the Upward and Downward Physical Appearance Comparison Scales (UPACS and DACS).

Methods

A total of 2,114 participants, consisting of 1,360 women without eating disorders (M age = 25.73, SD age = 6.84), 304 men without eating disorders (M age = 24.48, SD age = 6.34), and 450 women with eating disorders (M age = 27.11, SD age = 7.21), completed the UPACS and DACS as well as further questionnaires on appearance comparisons, eating disorder pathology, and self-esteem.

Results

Structural equation modeling confirmed the proposed one-factor structure of the original English-language version of the DACS but not of the UPACS. Both scales showed good internal consistency and test-retest reliability. The UPACS and DACS showed the expected correlations with related constructs, indicating acceptable construct validity, with some limitations for women with eating disorders.

Discussion

Overall, this study indicates that the German versions of the UPACS and DACS are psychometrically suitable for assessing upward and downward physical appearance comparisons in women and men without eating disorders and women with eating disorders in research and clinical practice.

Reflections of well-being: navigating body image, chronic energy deficiency, and nutritional intake among urban and rural adolescents

Background

Adolescent growth and development is a period of very specific nutritional problems. As a result of poor growth and development, 36.3% of adolescents in Indonesia are at risk of developing CED. The purpose of this study was to determine the description of body image, the incidence of Chronic Energy Deficiency (CED), and nutritional intake in adolescents in urban and rural areas.

Methods

This study used a descriptive quantitative design with a cross-sectional study conducted in Bandung and Sumedang on 387 adolescents aged 13-15 years. The instruments used in this study were body image questionnaire Figure Rating Scale (FRS) method, 2 × 24-h food recall, and anthropometry for Measuring mid upper arm circumference (MUAC).

Results

Results of this study showed that more than half of adolescents in urban (54.0%) and rural areas (61.7%) were at risk of CED, had negative body image perceptions in urban (69.1%) and rural areas (62.3%), and underconsumption of macronutrients in both urban and rural adolescents.

Conclusion

Most adolescents in urban and rural areas still consume less energy, carbohydrates, and protein. Perceived body image and nutrient intake contribute to the incidence of CED in adolescents.

Identifying methods used to manage weight and shape by first year university students: A qualitative analysis

OBJECTIVE

To identify current strategies used by first-year university students to lose weight, maintain weight, or change their body shape.

METHODS

First-year university students (n = 661) completed an open-ended, web-based survey. Cross-sectional data were analyzed qualitatively using a reflexive thematic approach to identify strategies used to lose weight, maintain weight, or alter body shape/composition. Thematic maps were constructed for each weight- and shape-related goal.

RESULTS

Four main types of strategies were used to achieve all three weight or shape-related goals among first-year college students: changes in diet, changes in exercise, self-monitoring, and disordered eating. One behavioral strategy observed across all weight-related goals was prioritizing protein consumption, including protein gained from supplementation. However, there were also differences in strategies by weight- or shape-related goal. For example, only participants aiming to lose or maintain weight reported mindful strategies for monitoring diet. Individuals aiming to alter body composition reported heterogeneity in goal-related intentions, targeting specific body parts through exercise, and extensive supplement use.

CONCLUSIONS

First-year college students use a variety of strategies to manage their weight and shape. Some strategies were observed across goals, whereas others are specific to the weight- or shape-related goal. More research is needed to understand the impacts, both positive and negative, of using the strategies identified in the present study.

The Sociostructural-Intersectional Body Image (SIBI) framework: Understanding the impact of white supremacy in body image research and practice

White supremacy and racial inequities have long pervaded psychological research, including body image scholarship and practice. The experiences of white, heterosexual, able-bodied, cisgender (predominantly college) women from wealthy, Westernized nations have been centered throughout body image research and practice, thereby perpetuating myths of invulnerability among racialized groups and casting white ideals and experiences as the standard by which marginalized bodies are compared. Body image is shaped by multiple axes of oppression that exist within systemic and structural systems, ultimately privileging certain bodies above others. In this position paper, we highlight how white supremacy has shaped body image research and practice. In doing so, we first review the history of body image research and explain how participant sampling, measurement, interpretive frameworks, and dissemination of research have upheld and reinforced white supremacy. Next, grounded in inclusivity and intersectionality, we advance the Sociostructural-Intersectional Body Image (SIBI) framework to more fully understand the body image experiences of those with racialized and minoritized bodies, while challenging and seeking to upend white supremacy in body image research and practice. We encourage other scholars to utilize the SIBI framework to better understand body inequities and the body image experiences of all people, in all bodies.

How evaluative pairings improve body dissatisfaction in adult women: evidence from a randomized-controlled online study

BACKGROUND

Many young women are dissatisfied with their bodies. This study investigated the effect on current body dissatisfaction levels of a newly developed evaluative conditioning procedure that paired self-similar and self-dissimilar images of bodies with positive and neutral affective images, respectively. We hypothesized that learning the contingency that self-similar bodies predict positive affectivity is one process that could aid in explaining how these procedures function.

METHODS

Adult women without disordered eating pathology participated in an online experiment with random assignment to an intervention or a control condition. All participants initially rated body images in self-similarity and were subsequently asked to categorize positive and neutral images by valence as quickly and accurately as possible. In the intervention condition, self-similar bodies systematically preceded positive images, and self-dissimilar images preceded neutral images, creating a similar body → positive contingency. Pairings in the control condition were unsystematic such that no contingency was present. We measured categorization latencies and accuracies to infer contingency learning as well as current body dissatisfaction immediately before and after exposure to the pairings. All participants further completed measures of trait body image concerns and disordered eating psychopathology at baseline, which we examined as moderators of an expected relation between condition assignment, contingency learning, and body dissatisfaction improvements.

RESULTS

We analyzed data from N = 173 women fulfilling the inclusion criteria. Moderated mediation analyses showed that assignment to the intervention (vs. control) condition predicted increased similar body → positive contingency learning, which in turn predicted improved body dissatisfaction post-intervention, but only among women with higher pre-existing trait body image concerns or disordered eating levels.

CONCLUSIONS

The findings point toward the relevancy of further exploring the utility of pairing procedures. Similar body → positive contingency learning predicted improved body dissatisfaction in individuals with normatively high body image concerns, which suggests pairing procedures could help inform future research on reducing body dissatisfaction.

Body dissatisfaction and low self-esteem in elementary school-aged children: the role of media pressure and trust in parent-child relationships

Studies have indicated that the media plays a role in the development of body dissatisfaction in children. Nevertheless, there is limited understanding of the protective factors that may reduce this association, such as the parent-child relationship. Therefore, this study investigates children's body dissatisfaction and self-esteem and the role of media pressure and a trust in parent-child relationships herein. A sample of n = 246 participants (59.8% girls, aged 8-10) was recruited. Children completed self-report questionnaires that assessed body dissatisfaction, self-esteem, media pressure, and trust in parent-child relationships. Results revealed that higher scores on media pressure were linked to increased body dissatisfaction and decreased self-esteem. On the other hand, higher scores on trust in mother and father were associated with lower levels of body dissatisfaction and higher levels of self-esteem. However, the presence of trust in parent-child relationships did not attenuate the impact of media pressure on body dissatisfaction or self-esteem. Further investigation is necessary to gain a deeper understanding of how sociocultural and interpersonal factors interact and contribute to the development of body image problems. While current prevention and intervention programs predominantly focus on the individual, it may be beneficial to place greater emphasis on the family environment.

Exploring the tripartite influence model of body image and disordered eating among adolescent girls living in Australia, China, India, and Iran

The aim of this study was to evaluate the tripartite influence model of body image and disordered eating among 12-18-year-old girls (N = 900) living in Australia (n = 184), China (n = 293), India (n = 223), and Iran (n = 200). Participants completed measures about appearance pressures from family, peers, and media, thin-ideal internalization, appearance comparisons, appearance satisfaction, and disordered eating. Results indicated that media- pressures were most salient in Australia, whereas Iranians perceived family pressures to be the strongest. Indians felt the most pressure to look attractive from their family and peers, whereas Chinese felt similar levels of pressure from family, peers, and media. Path analyses suggested direct associations from one or more sociocultural factors to appearance satisfaction or disordered eating, with indirect paths via thin-ideal internalization and appearance comparisons emerging in all countries. Certain sociocultural factors contributed more strongly to the internalization of ideals and appearance comparisons within some countries. Multigroup path analyses demonstrated some cross-cultural variations in the strength of the pathways. Findings extend cross-cultural support for a modified tripartite influence model emphasizing culture-based specificities that can further guide preventative efforts to improve body image and eating attitudes among young girls in these four countries.

Birds of a feather flocking together on Instagram: How racially similar followers and followings on Instagram are linked to young women's body image

In light of recent studies demonstrating the detrimental effects of social media use on young women's body image, we examined the racial composition of young women's Instagram followers, as well as the racial composition of the individuals in young women's followed Instagram accounts, in relation to their appearance ideals and body image. Based on social identity theory (Tajfel & Turner, 1979), we tested two main propositions. First, women who have racially similar followers and followed accounts will be more likely to internalize body ideal preferences that are relevant to their in-group (i.e., thinness for Asian-American and White women; curviness for Black and Latina women). Second, following and being followed by people of one's racial identity in-group will have ameliorative effects on young women's body image (i.e., more body appreciation; less body dissatisfaction). Our sample included 533 U.S. women who identified as Asian-American (n = 97), Black (n = 101), Latina (n = 98), or White (n = 237). The results provided more support for the notion that racially similar followers and accounts followed are related to better body image outcomes rather than to the internalization of body ideals. Specifically, following a higher percentage of racially similar accounts was positively associated with body appreciation among Asian-American and White participants and negatively associated with body dissatisfaction among Asian-American participants. Likewise, being followed by a higher percentage of racially similar others was positively associated with body appreciation among Asian-American, Black, and White participants, and negatively associated with body dissatisfaction among Latina participants. The findings are discussed in light of social identity theory.

Exploring risk factors of drive for muscularity and muscle dysmorphia in male adolescents from a resource-limited setting in Burkina Faso

In low-income countries, Muscle Dysmorphia (MD) has only been investigated in adult south African amateur-bodybuilders. To date, there is no epidemic study about MD or its cardinal symptom "drive for muscularity" (DFM) and its impact on young men's lives in African low-income settings. We analyzed a population-representative cross-sectional study of 838 adolescent males aged 12-20 in the rural northwestern Burkina Faso. Participants were assessed for MD with the research criteria of Pope and its cardinal symptom DFM based on the DFM scale (DMS). Since DFM has not been studied in a comparable sample so far, all possible influencing variables were examined exploratively in a linear regression model. Many respondents were underweight (41.5%) and few overweight (1.3%). No-one met standard clinical MD criteria. While 60.1% of 837 wished to be more muscular, only 8.7% of 824 desired a lower body-fat percentage. Regression analysis revealed that higher DMS scores were associated with greater internalization of the muscular body ideal, going to school, living in a rural area, older age, and a history of having faced sexual harassment or assault, but not with media exposure. Our results show that levels of DMS in Burkinabe adolescents were elevated. Risk factors for DFM in environmental circumstances where undernutrition and poverty are common are discussed.

Can I Love My Body Even if It Doesn't Look Like the Porn Stars'? Longitudinal Associations Between Pornography Use Frequency and Body Appreciation in a Diverse Sample of Adolescents

Online technologies could play an important role in the sexual development of adolescents as they watch more pornography than before. Pornography may relate to adolescents' perceptions of their bodies, especially among those identifying as a sexual and/or gender minority (SGM) as they have an increased risk of body image concerns compared to their heterosexual, cisgender (HC) peers. The present study examined the cross-sectional and longitudinal associations over 3 years between adolescents' pornography use frequency and body appreciation, considering potential gender and sexual orientation-based differences. Results from linear univariate and parallel processes latent growth curve models with a multi-group approach among 2904 adolescents (MageT1 = 14.5 years, SD = 0.61; 51.4% girls, 16.3% sexual minority) demonstrated that HC and SGM girls' body appreciation slightly decreased over time. Moreover, HC boys, HC girls and SGM girls' pornography use frequency slightly increased over time. Cross-sectionally, greater pornography use frequency was associated with lower levels of body appreciation in HC girls and SGM boys, with a small effect size. However, longitudinally, pornography use frequency and body appreciation were not related to each other in either group. Our findings support that pornography use, in the short term, is negatively associated with adolescents' body appreciation, although these associations might not hold in the long term. Adolescents may be more critical of body ideals represented in pornography as they learn to think with more discernment about the pornographic depictions of bodies and sexuality.

The validity of the Czech version of Body Appreciation Scale-2 for adolescents

BACKGROUND

Understanding the formation of body image is critical for the prevention and treatment of eating disorders, especially in adolescence, when body image develops significantly. One of the important facets of body image is body appreciation, which consists of positive feelings and attitudes towards the body regardless of its perceived "flaws". To measure body appreciation, Body Appreciation Scale-2 (Tylka and Wood-Barcalow in Body Image 12:53-67, 2015a), a unidimensional 10-item measure, has been developed and routinely used in body image research. The current study examined the validity (i.e., factor structure, gender and age invariance, associations with other constructs) of the Czech version of Body Appreciation Scale-2 for adolescents.

METHODS

The study used two large samples of Czech adolescents, aged 13-18 (N1 = 613, M = 15.5, 52% girls; N2 = 1,530, M = 15.4, 50% girls). The data were collected in August 2021 (N1) and November 2020 (N2) through an online survey. For the data analysis, we used confirmatory factor analysis (CFA), multi-group confirmatory factor analysis (MG-CFA), and Structural Equation Modeling (SEM).

RESULTS

Our findings supported the proposed unidimensional factor structure and the gender (i.e., girls, boys) and age (i.e., 13-15, 16-18) scalar invariance of the Czech version of Body Appreciation Scale-2. The data also showed the expected positive correlations with body satisfaction and self-esteem, and negative correlations with media-ideal internalization, appearance schematicity, and depression. Furthermore, we discovered that body appreciation was more strongly connected to media-ideal internalization and depression for girls than boys.

CONCLUSIONS

The present study provided robust evidence that supports the validity of the Czech version of Body Appreciation Scale-2 and its usability for the assessment of body appreciation in Czech adolescents. We also proposed future directions for the research on body appreciation based on the explored gender differences.

Chinese TikTok (Douyin) challenges and body image concerns: a pilot study

BACKGROUND

Social media content on Western platforms promoting thinness, or thinspiration, has been found to negatively affect body image perception of users. Less is known about non-Western social media use and its effects on body image concerns. Chinese TikTok, known as Douyin, is a popular short video platform with 600 million daily active users. Recent trends on Douyin encourage users to demonstrate thinness through participation in 'body challenges'. This paper argues that such content is comparable to thinspiration, however, to date hardly any research has been undertaken on these challenges. Thus, this pilot study aimed to analyse the content of three viral challenges and investigate their impact on Douyin users.

METHODS

Thirty most viewed videos were collected for three challenges (N = 90): the Coin challenge, the A4 Waist challenge, and the Spider leg challenge. Videos were coded for variables relating to thin idealisation, including thin praise, sexualisation and objectification, and analysed through content analytic methods. Video comments (N ≈ 5500) were analysed through thematic analysis, and main themes were identified.

RESULTS

Preliminary findings showed that participants who objectified their bodies to a greater extent expressed more negative body image concerns. In addition, comments on the videos had themes of thin praise, self-comparison, and promotion of dieting behaviours. In particular, videos of the A4 Waist challenge were found to incite more negative self-comparison in viewers.

CONCLUSION

Preliminary findings suggest all three challenges promote the thin ideal and encourage body image concerns. Further research about the broader impact of body challenges is needed.

Associations between social media use, fitness- and weight-related online content, and use of legal appearance- and performance-enhancing drugs and substances

Prior research has documented the connection between social media use and engaging with fitspiration with body dissatisfaction, disordered eating behaviors, and various health risk behaviors (e.g., substance use). However, gaps remain in the knowledge base on whether social media use and engaging with fitness- and weight-related online content are associated with the use of legal appearance- and performance-enhancing drugs and substances (APEDS; e.g., whey protein), which was the aim of this study. Data from participants ages 16-30 years in Canadian Study of Adolescent Health Behaviors (N = 2731) were analyzed. Multiple modified Poisson regression analyses were conducted to determine the associations between hours per day of social media use and any engagement with fitness- and weight-related online content in the past 30 days and use of 10 different legal APEDS in the past 30 days. Greater time on social media was significantly associated with use of energy drinks and pre-workout drinks or powders in the past 30 days. Engaging with fitness- and weight-related online content was significantly associated with the use of caffeine, creatine monohydrate, pre-workout drinks or powders, probiotics, protein bars, and whey protein powders or shakes in the past 30 days. These findings expand prior research on the correlates of social media use and engagement with fitness- and weight-related online content among young people and have important implications for healthcare and public health professionals, as well as technology companies.

Social media, traditional media, and other body image influences and disordered eating and cosmetic procedures in Malaysia, Singapore, Thailand, and Hong Kong

In this study, we investigated the association between perceived sociocultural influences and the 3-month prevalence of disordered weight-control behaviors and lifetime prevalence of cosmetic procedures in four Asian countries, and if these associations were modified by gender. We conducted a cross-sectional online survey in September 2020 among adults ages 18-91 years (N = 5294) in Malaysia, Singapore, Thailand and Hong Kong. The 3-month prevalence of disordered weight control behaviors ranged from 25.2 % (Singapore) to 42.3 % (Malaysia), while the lifetime prevalence of cosmetic procedures ranged from 8.7 % (Singapore) to 21.3 % (Thailand). Participants who perceived their body image to be influenced by sociocultural factors were more likely to engage in disordered weight control behaviors (RRs ranged from 2.05 to 2.12) and have cosmetic procedures (RRs ranged from 2.91 to 3.89) compared to participants who perceived no sociocultural influence. Men who were influenced by traditional or social media were more likely to engage in disordered weight control behaviors and have cosmetic procedures than similarly influenced women. The high 3-month prevalence of disordered weight control behaviors and lifetime prevalence of cosmetic procedures in Asia is concerning. More research is needed to develop effective preventive interventions in Asia for men and women to promote a healthy body image.

Socio-cultural power of social media on orthorexia nervosa: An empirical investigation on the mediating role of thin-ideal and muscular internalization, appearance comparison, and body dissatisfaction

As social media continues to penetrate users' daily lives, concerns about its negative impact on body image issues and eating disorders are becoming focuses of research. It remains unclear whether social media should be held responsible for promoting orthorexia nervosa-a problematic and extreme fixation on healthy eating. The present study draws on socio-cultural theory and tests a social media-based model in the context of orthorexia nervosa to enhance knowledge of social media's influence on body image issues and orthorectic eating tendencies. The socio-cultural model was tested using structural equation modeling based on responses from a German-speaking sample (n = 647). The results indicate that social media users' involvement with health and fitness accounts is associated with higher orthorectic eating tendencies. Thin-ideal and muscular internalizations mediated this relationship. Interestingly, body dissatisfaction and appearance comparison were not mediators, which can be attributed to the characteristics of orthorexia nervosa. Higher involvement with health and fitness accounts on social media was also related to higher appearance comparisons. The results highlight the powerful influence of social media on orthorexia nervosa and the relevance of socio-cultural models in investigating the mechanisms underlying this influence.

Integrating social media variables as predictors, mediators, and moderators within body image frameworks: Potential mechanisms of action to consider in future research

In this article, we consider how social media variables may be integrated as predictors, mediators, and moderators within dominant theoretical frameworks of body image in order to identify potential mechanisms of action that can be empirically examined in future research and used to direct prevention and intervention efforts. To achieve this goal, we first articulate social media variables that have been investigated as predictors, mediators, and moderators in body image research. Next, we present the following critical and sociocultural theoretical frameworks: social comparison theory, tripartite influence model, objectification theory, developmental theory of embodiment, acceptance model of intuitive eating, cultivation theory, and uses and gratifications theory. Additionally, we present the theory of development of critical body awareness, a newly developed model that may provide further insight regarding the relationships between social media and body image-related outcomes. For each model, we articulate extant research that has explored social media variables within its context and explicate how social media variables could potentially be studied as predictors, mediators, and moderators within its structure. To conclude, we address pertinent limitations and gaps within this research space that could direct future research across the theoretical frameworks.

Engagement with social media content results in lower appearance satisfaction: An experience sampling study using a wrist-worn wearable and a physical analogue scale

Social media use is consistently associated with more negative body image, but much of this literature is cross-sectional and/or lacks ecological validity. To overcome these limitations, we examined associations between everyday social media engagement and appearance satisfaction using an experience sampling method. Fifty participants from Central Europe completed a 14-day experience sampling phase in which they reported their appearance satisfaction at two random time-points each day, as well as following active engagement with social media content, using a wrist-worn wearable and a physical analogue scale (PAS; i.e., angle of a participant's forearm between flat and fully upright as a continuous response scale). Results indicated that engagement with social media content was significantly associated with lower appearance satisfaction. Additionally, we found that engagement with the content of known others was associated with significantly lower appearance satisfaction than engagement with the content of unknown others. These effects were stable even after controlling for participant demographics, active vs. passive daily social media use, and body image-related factors. These results provide evidence that everyday social media engagement is associated with lower appearance satisfaction and additionally provides preliminary support for the use of a PAS in body image research using an experience sampling method.

Black adolescents' appearance concerns, depressive symptoms, and self-objectification: Exploring the roles of gender and ethnic-racial identity commitment

There is a dearth of research examining Black adolescents' body image, with even less work examining gender differences or the influence of ethnic-racial identity (ERI) commitment. It is critical to understand how culturally relevant aspects of appearance-beyond commonly measured ideals such as thinness and muscularity-are particularly relevant to Black adolescents. The present study of Black youth (n = 252; 55% girls, 45% boys, ages 13-18, M_age = 15.5) explored the roles of gender and ERI commitment in the associations between skin tone, hair, and facial satisfaction and appearance esteem, depressive symptomatology, and self-objectification. With a few exceptions, satisfaction with skin tone, hair, and face were significantly associated with higher appearance esteem and lower self-objectification and depressive symptoms, even when controlling for weight and muscle tone satisfaction. Findings were similar across genders, with some associations stronger among Black girls relative to boys. Among youth with higher ERI commitment, associations were stronger between skin tone, hair, and facial satisfaction and some indicators of wellbeing. Findings elucidate the role of culturally relevant appearance concerns of Black adolescents and the potential benefits of ERI commitment. This work can inform culturally sensitive research practices and therapeutic interventions related to Black youth's body image experiences.
