Body image self-conscious emotions get worse throughout adolescence and relate to physical activity behavior in girls and boys

The Relationships Between Body-Related Emotion Intolerance and Restrictive Eating as a Function of Multidimensional Perfectionism

OBJECTIVE

Emotion intolerance and perfectionism are two maintaining mechanisms to eating disorder symptomology. However, it is unclear how these mechanisms relate to one another. This study explored whether perfectionism is a vulnerability factor for facets of restrictive eating in the context of body-related emotions.

METHODS

Female undergraduate students (N = 148) completed questionnaires assessing baseline levels of self-critical perfectionism and personal standards perfectionism. Participants then engaged in an ecological momentary assessment protocol where body-related emotion intolerance and restrictive eating facets (cognitive restraint and behavioral restriction) were assessed over 10 consecutive days. Multilevel modeling and simple slopes analysis were used to explore these moderated relationships. Within-person (Level 1 body-related emotion intolerance) and between-person (Level 2 perfectionism dimensions) relationships were examined.

RESULTS

Based on the analyses, both self-critical and personal standards perfectionism dimensions interacted with body-related emotion intolerance to predict increases in restrictive eating facets.

CONCLUSION

These findings indicate that personal standards perfectionism, though conceptualized as the less maladaptive dimension of perfectionism, should not be ignored when conceptualizing and intervening with restrictive eating. Recommendations are provided on how to refine treatment targets to be more attuned with situations that elicit body-related emotion intolerance.

Daily Bursts of Body-Related Self-Conscious Emotions Relate to Attention and Reaction Time in Adolescents

Body-related self-conscious emotions (e.g., shame, guilt, envy, and embarrassment), which are particularly salient in sport, are foundational to adolescents' attention and performance. Adolescents' (N = 72) self-conscious emotions and attention were examined using self-reported single-item measures across 4 days. After completing these measures, adolescents' reaction time was measured using a hand laterality judgment task. Data were analyzed using multilevel regression models. Controlling for age and gender, attention, and reaction times were regressed on body-related self-conscious emotions in separate multilevel models. Results indicate that, on the days that adolescents experience higher levels of body-related shame, envy, and embarrassment, they had more difficulty blocking out distracting thoughts. Further, higher levels of body-related embarrassment related to longer reaction times. This study is consistent with previous research indicating that body image may significantly impact motor performance. In addition to adolescents' performance, these results may have implications for adolescents' participation and enjoyment of sport experiences.

Associations among negative weight-related experiences, weight bias internalization, and body-related self-conscious emotions in adolescents: A daily diary study

INTRODUCTION

The present study examined the between- and within-person associations among negative weight-related experiences, weight bias internalization, and body shame, embarrassment, and pride in adolescents.

METHODS

Participants were 93 Canadian students (Mage = 15.54, 59.10% girls, 40.86% white) who completed a 5-day daily diary study in 2021. Multilevel models were estimated to examine the between- and within-person associations, as well as the cross-level interactions.

RESULTS

Fifty-nine negative weight-related experiences were reported from 22 participants (23.66%) over the 5-day study period. Adolescents with higher average negative weight-related experiences (OR = 19.60, 95% CI = 1.90-202.67) and weight bias internalization (OR = 3.66, CI = 2.07-6.46) had greater odds of reporting shame. Similarly, higher average negative weight-related experiences (OR = 16.29, CI = 3.65-72.75) and weight bias internalization (OR = 2.08, CI = 1.53-2.82) was associated with greater odds of embarrassment. No within-person effects were noted, such that reporting more negative weight-related experiences or weight bias internalization than one's own average was not related to body emotions.

CONCLUSIONS

This distinction underscores that the persistent, rather than episodic, aspects of negative weight-related experiences and weight bias internalization are most impactful on adolescents' body image. These findings have implications for recruitment and screening for individual-level interventions for internalized weight bias and body image, and highlight the need for system-level policies and changes that prohibit negative weight-related experiences and messages to reduce likelihood of internalizing weight bias among adolescents.

Optimizing athletic engagement and performance of obese students: an adaptive approach through basketball in physical education

Introduction

Obesity in adolescents is associated with reduced physical activity and athletic engagement, highlighting the need for tailored physical education programs. This study evaluated the effects of a 7-week adapted basketball program on the performance and athletic engagement of students with obesity.

Methods

Sixty-two students with obesity (23 boys, 39 girls, aged 15-17) were randomly assigned to an experimental group (EG, n = 30; 11 boys, 19 girls) participating in adapted basketball sessions or a control group (CG, n = 32; 12 boys, 20 girls) attending standard basketball lessons. Both groups completed 52-minute sessions twice weekly. Pre- and post-intervention assessments included a questionnaire evaluating perceptions of physical education and athletic performance during final matches.

Results

The EG showed significant improvements in interest, motivation (p < 0.05), perceived competence (p < 0.001), and reduced exercise difficulty (p < 0.001). Perceived fitness levels increased significantly only in EG girls (p = 0.013). In contrast, no significant changes were observed in the CG before and after the intervention for any of the parameters. During matches, the EG outperformed the CG, with more successful shots (girls: p = 0.0004; boys: p = 0.012), fewer missed shots (girls: p = 0.033; boys: p = 0.046), and more successful passes (p = 0.032, η² = 0.042).

Discussion

These results demonstrate that adapted physical education programs can serve as effective interventions for improving physical activity and promoting inclusion among adolescents with obesity while also serving as a preventive measure against obesity.

Impact of neighborhood safety on adolescent physical activity in Saudi Arabia: gender and socio-economic perspectives

Background and objectives

Adolescent physical activity is a critical determinant of long-term physical and mental health. However, the factors influencing activity levels remain underexplored in rapidly urbanizing regions such as Saudi Arabia, where changing built environments pose unique challenges.

Methods

This study examined the relationship between neighborhood safety perceptions and physical activity levels among 1,500 adolescents aged 14-17 years in the cities of Riyadh, Jeddah, and Dammam, representing a mix of urban and suburban settings. This study used a cross-sectional design with data collected through a validated self-reported questionnaires and interviews; the data were analyzed through multivariate regression.

Results

The results indicate that adolescents who perceived higher traffic-related safety concerns engaged in 30% less physical activity compared to those in safer neighborhoods (p < 0.01). Female adolescents were 20% more likely than male adolescents to report safety concerns (p < 0.05), while those residing in villas engaged in 15% more physical activity than their peers living in flats (p < 0.05).

Conclusions

These findings underscore the significant role of neighborhood safety in shaping adolescent health behaviors, particularly regarding traffic management and accessibility. These results contribute to the growing evidence regarding the influence of built environments on youth health and wellbeing in rapidly urbanizing regions. The study offers actionable policy recommendations for urban planners and public health officials to create safer, more inclusive environments that encourage physical activity, especially among female adolescents. Future research should adopt longitudinal designs and incorporate objective measures, such as wearable activity trackers, to assess the long-term impact of neighborhood safety interventions on adolescent health outcomes.

Exploring adolescents' experiences navigating the intersection of their gender, sport, and dietary identities: an interpretative phenomenological study

Not all adolescents have positive sport experiences. Research has repeatedly identified ties between unfavorable eating patterns and food beliefs (i.e., a dietary identity) that hinder an athletes' health and performance. Gender norms and pressures over idealized bodies (e.g., boys are muscular whereas girls are thin) play a critical role in the manifestation of unfavorable eating habits. However, most research has focused on the experiences of athlete girls in elite sport spaces (e.g., high performance), leaving gaps in our understanding of how diverse youth in high school spaces are impacted. To address this gap, we aimed to explore the intersections between adolescents' sport, dietary and gender identities in high school. We conducted 33 interviews with high school athletes (n = 9 girls and n = 9 boys) and non-athletes (n = 4 non-binary, n = 6 boys and n = 5 girls) using methods informed by an interpretative phenomenological approach. We generated three themes capturing adolescents' experiences: (1) De-gendering protein and muscles; (2) Food displays what I value; and (3) Being [too] masculine is bad. Athletes recognized ties between masculinity and sport, but spoke about traditionally masculine eating habits (e.g., valuing protein) and body ideals (e.g., being muscular) as part of their athletic identity, not gender. Regardless of sport involvement, adolescents altered their outward expression of their dietary habits to demonstrate pieces of their identities, like being an athlete (e.g., eating protein) or feminine (e.g., smaller bites). Adolescents also spoke about using food to pursue idealized bodies that show deviation from traditional gender norms. Finally, adolescents held conflicting views about masculinity as being both toxic and useful for competition. By understanding identity intersections, coaches, trainers, parents, and sport decisions-makers can make more informed decisions about sport policy, programs, and practice that involve dietary advice to support this population.

Gender-specific effects of self-objectification on visuomotor adaptation and learning

Self-objectification can influence cognitive and motor task performance by causing resources to be reallocated towards monitoring the body. The present study investigated effects of recalling positive or negative body-related experiences on visuomotor adaptation in women and men. Moderating effects of positive and negative affect were also explored. Participants (100 women, 47 men) were randomly assigned to complete a narrative writing task focused on body-related pride or embarrassment before performing a visuomotor adaptation (cursor rotation) task. A retention test of the visuomotor task was completed after 24 h. Men in the embarrassment group were more impacted by the initial cursor rotation (in movement time and accuracy) than the pride group and showed poorer retention of movement time. Women in the embarrassment group were less accurate than the pride group following initial rotation. In women only, affect modulated the effects of the negative recalled scenario. Further analysis indicated that the differences between embarrassment and pride groups remained in a subset of participants (34 women, 28 men) who explicitly referred to their own movement within their recalled scenarios. These results demonstrate that recalling body-related self-conscious emotions can impact visuomotor adaptation and learning in both women and men, but effects may differ between genders.

Assessment of Binge Eating Behavior, Body Shape Concerns, and Associated Factors among Female Adolescents of Northern Saudi Arabia: A Cross-Sectional Study

Globally, binge eating behavior has emerged as a significant public health concern, especially among female adolescents. Body shape concerns in female adolescents can lead to body dissatisfaction and other mental health issues. Using a cross-sectional study design, we evaluated the frequency of binge eating behavior, body shape concerns, and associated factors among 400 female adolescents. We utilized a pretested Arabic binge eating scale (BES) and a body shape questionnaire-shorter version (BSQ-8C) to collect the required data. We performed Spearman's correlation analysis to find the strength and direction of the correlation between the BES and BSQ-8C scores. Finally, we applied binomial logistic regression analysis to identify the predictors of body shape concerns. Of the studied participants, 5.5% and 6.2% had medium and severe binge eating behavior. We found a significant positive correlation between the BES and BSQ-8C scores (rho = 0.434, p < 0.001). Also, we found that body shape concerns were significantly higher among the monthly family income category of 5000 to 7000 SAR (p = 0.005), the severe binge eating categories (p = 0.009), and obese adolescents (p = 0.001). The present study results can be applied to the development of focused interventions and strategies to address these concerns in this group.

Evaluating the Impact of the Nirvana Fitness and Functional Training Programs on Young Women's State Body Appreciation and Its Correlates

This study examined the effects of the Nirvana Fitness (NF) program on state body appreciation (BA) and its correlates, as well as the mechanisms that could explain these changes. The study participants were allocated to NF (n = 21) and functional training (control, n = 22) groups and participated in an 8-week exercise intervention. The mean age was 24.4 ± 6.7. The participants filled out online questionnaires on state measures of BA, body surveillance (BS), functionality appreciation, body-mind connection, mindfulness in physical activity (SMS-PA), intrinsic exercise motivation (IM), satisfaction of basic psychological needs, and perceived physical fitness (PPF) immediately after the first and last sessions. The results revealed a significant improvement in state BA and its correlates in both groups, with no changes in PPF in the NF group or IM in either group. An interaction between group and time effects was revealed in a change of relatedness, indicating a stronger effect in the NF group. Positive changes in SMS-PA, BS, and satisfaction of the need for relatedness significantly predicted improvement in state BA. These findings highlight the importance of targeting mindfulness, body surveillance, and relatedness during physical activity in interventions aimed at promoting positive body image in university-aged women.

Impact of symptoms, experiences, and perceptions of the menstrual cycle on recreational physical activity of cyclically menstruating individuals: A systematic review

OBJECTIVE

The menstrual cycle often presents barriers to participation in daily life activities, including physical activity (PA), which is a cornerstone of health and well-being. The purpose of this systematic review was to explore and summarize the impact of symptoms, experiences, and perceptions of the menstrual cycle on recreational PA (RPA), including sports, exercise and active recreation, in the general population.

METHODS

Six databases were searched for studies that investigated the impact of the menstrual cycle on PA among individuals who were cyclically menstruating, healthy, and not involved in professional sports training.

RESULTS

The search yielded 3025 studies that were screened for relevance and eligibility, resulting in 25 eligible studies, which were found to be of moderate-to-high quality following a quality and risk-of-bias assessment. Thematic synthesis of qualitative and quantitative data from the selected studies, constituting 16,557 adults and 3715 adolescents, identified the impact of menstrual symptoms on the physical and psychological capability to participate in RPA, social opportunity barriers to RPA (e.g., social pressure due to the sociocultural taboo against menstruation), as well reflective (knowledge) and automatic (habit) motivation on RPA behaviours.

CONCLUSION

The variability in menstrual symptoms and corresponding experiences suggested the need for an individualized approach to RPA promotion. Furthermore, this review highlighted the need to address the sociocultural taboo against menstruation, as well as improve the provision of knowledge and resources related to the menstrual cycle and RPA, in order to promote and facilitate RPA for cyclically menstruating individuals throughout the menstrual cycle.

Emotion in Motion: Weight Bias Internalization, Exercise Avoidance, and Fitness-Related Self-Conscious Emotions

Weight bias internalization (WBI), the process of internalizing negative attitudes and stereotypes towards overweight individuals, significantly impacts self-worth and health behaviors, such as exercise avoidance. In the current study, we focused on the mediating role of fitness-related self-conscious emotions, particularly shame and guilt. A cross-sectional study involving 150 self-described overweight Dutch women (age M = 49.63 ± 10.72) was conducted online. Participants completed measures assessing weight bias internalization, exercise avoidance, and body/fitness-related self-conscious emotions. Data were analyzed using linear regression and mediation analysis, controlling for age, BMI, and exercise frequency. The results show that weight bias internalization, guilt-free shame, and shame-free guilt uniquely predict exercise avoidance. Guilt-free shame partially mediated the relationship between weight bias internalization and exercise avoidance, indicating that increased internalized weight bias led to higher levels of guilt-free shame, which in turn contributed to exercise avoidance. Shame-free guilt did not act as a unique mediator. These findings underscore the importance of addressing weight bias internalization and fitness-related self-conscious emotions, particularly guilt-free shame, in interventions targeting exercise avoidance among overweight individuals. Strategies promoting self-compassion and reducing shame may prove beneficial in improving exercise behaviors and overall well-being.

Body-related emotions and subsequent physical activity behaviour: An ecological momentary assessment

Body-related shame and guilt are theorized to be time-varying affective determinants of physical activity, yet research has predominantly relied on self-report measures of physical activity and between-person associations. To address these limitations, the present study used ecological momentary assessment to examine within- and between-person associations between body-related shame and guilt, and subsequent time spent in moderate-to-vigorous physical activity (MVPA) measured by continuously worn accelerometers. University students (n = 98; 79.6% female; mage = 19.45) were prompted 49 times over seven days to report body-related shame and guilt, and wore activPAL accelerometers to monitor movement behaviours. Higher levels of within-person body-related guilt, but not shame, were associated with increased subsequent time spent in MVPA. Contrary to existing literature, neither body-related shame nor guilt demonstrated a significant association with average levels of MVPA between individuals. These findings support theoretical propositions that body-related guilt may impact engagement in physical activity in daily life.

Body-related shame disrupts attentional focus over time in adolescence

INTRODUCTION

Body-related shame is a negative self-conscious emotion that is heightened during adolescence and is associated with several adverse outcomes. Of particular interest, and informed by Objectification Theory, body-related shame may impact attentional focus because the experience of this intense emotion may limit cognitive resources required to effectively engage in tasks. The purpose of the present study was to examine the association between body-related shame and attentional focus over time during adolescence.

METHODS

Adolescents (n = 160; Mage  ± SD = 16.05 ± 0.98; 80% self-identifying girls) completed an online survey in 2022 at baseline (Time 1) and 3 months later (Time 2). Stepwise regression was used to test the association between body-related shame and attentional focus, with weight perception included as a covariate.

RESULTS

The regression model demonstrated that higher body-related shame predicted poorer attentional focus 3 months later (β = -0.44, p < .001), after controlling for weight perception (14% variance explained in attention).

CONCLUSIONS

Findings support and extend theoretical tenets by highlighting the potential importance of targeting body-related shame to reduce the negative impact on attentional focus among adolescents.

An integrative model of weight stigma, body image, and physical activity in adolescents

Negative weight-related experiences and internalized weight stigma have been associated with poorer body image and reduced physical activity in adolescents. However, exploring body image and physical activity as discrete weight stigma outcomes fails to consider the theoretically- and empirically-supported covariation between the two. The present study tested a novel integrated model of the associations among negative weight-related experiences and internalized weight stigma (via weight-related distress), body image (shame, authentic pride, body appreciation), and physical activity. Canadian adolescents (N = 311, M_age ± SD = 16.00 ± 1.01, 75.5% girls) completed a cross-sectional self-report survey. A structural equation model with maximum likelihood robust estimation was tested. Higher negative weight-related experiences were indirectly associated with poorer body image (i.e., higher shame; lower authentic pride and appreciation) through higher weight-related distress. Authentic pride was associated with moderate-to-vigorous physical activity. Higher negative weight-related experiences were indirectly associated with lower physical activity through higher weight-related distress and lower body-related authentic pride. These findings elucidate targetable individual mechanisms and larger systems that could improve body image and foster physical activity among adolescents who encounter negative weight-related experiences and internalized weight stigma.

Association between Motivation in Physical Education and Positive Body Image: Mediating and Moderating Effects of Physical Activity Habits

Concerns about body image might prevent adolescents from participating in physical education (PE) classes and physical activities during leisure-time. In this cross-sectional study, we assessed the relationships between teacher support of autonomy, student motivations for PE, and positive body image, in a sample of Lithuanian adolescents. A total of 715 adolescents (51.89% girls) participated in the study. Ages ranged from 14 to 18 years, with a mean age of 16.00 (SD = 0.79) for girls and 15.99 (SD = 0.75) for boys. The questionnaire consisted of demographic questions, the Learning Climate Questionnaire, the Revised Perceived Locus of Causality in Physical Education Questionnaire, the Body Appreciation Scale-2, the Self-Report Habit Index for Physical Activity (PA), perceived physical fitness (PPF), and Godin Leisure-Time Exercise Questionnaire. The results showed that teacher support for students' autonomy was associated with higher positive body image. In adolescent girls, autonomous motivation for PE was the mediator between teacher support of autonomy and positive body image. The associations between self-determined motivation in PE and positive body image were mediated by PPF on one hand, and through PA habits and PPF on the other hand of the structural equation model (in girls). PA habits moderated associations between PE motivation and PPF. Associations between PE motivation and PPF were stronger in girls with the lowest PA habits compared to girls with mean PA habits. These results suggest that PE classes are important for promoting students' positive body images. PE teachers are advised to use pedagogical strategies that promote the self-determined motivation of students for PE. Increased self-determined motivation for physical education might be an effective strategy for physical self-perception and positive body image promotion in adolescent girls, especially those with low PA habits.
