RESUMO

The physical boundaries of our body do not define what we perceive as self. This malleable representation arises from the neural integration of sensory information coming from the environment. Manipulating the visual and haptic cues produces changes in body perception, inducing the Full Body Illusion (FBI), a vastly used approach to exploring humans' perception. After pioneering FBI demonstrations, issues arose regarding its setup, using experimenter-based touch and pre-recorded videos. Moreover, its outcome measures are based mainly on subjective reports, leading to biased results, or on heterogeneous objective ones giving poor consensus on their validity. To address these limitations, we developed and tested a multisensory platform allowing highly controlled experimental conditions, thanks to the leveraged use of innovative technologies: Virtual Reality (VR) and Transcutaneous Electrical Nerve Stimulation (TENS). This enabled a high spatial and temporal precision of the visual and haptic cues, efficiently eliciting FBI. While it matched the classic approach in subjective measures, our setup resulted also in significant results for all objective measurements. Importantly, FBI was elicited when all 4 limbs were multimodally stimulated but also in a single limb condition. Our results behoove the adoption of a comprehensive set of measures, introducing a new neuroscientific platform to investigate body representations.

RESUMO

Despite high levels of muscularity concerns among sexual-minority men, most of the existing literature on the drive for muscularity and muscle dysmorphia focuses on heterosexual men and has mainly been conducted in Western and English-speaking regions. The present study aimed to evaluate the psychometric properties of the Drive for Muscularity Scale (DMS) and the Muscle Dysmorphic Disorder Inventory (MDDI) in Brazilian cisgender gay and bisexual adult men who were 18-50 years old. We evaluated the factor structure of both measures using a two-step, split-sample exploratory (EFA; n = 704) and confirmatory (CFA; n = 705) factor-analytic approach, which supported the original three-factor structure of the MDDI and resulted in a reduced two-factor solution with 13 items for the DMS. Convergent validity was supported through associations of the DMS and the MDDI with eating disorder symptoms, body-ideal internalization, self-objectification beliefs and behaviors, and body appreciation measures. Additionally, we found good internal consistency, and test-retest reliability of both measures. Results support the validity and reliability of the DMS and the MDDI in Brazilian cisgender gay and bisexual adult men and will support future studies exploring these constructs in Brazilian sexual-minority men.

RESUMO

Research suggests that exposure to social networking sites portraying a thin and often sexualized beauty ideal reduces young women's body satisfaction, while exposure to body-positive content improves it. However, it is unclear whether sexualization could impair the beneficial effects of body-positivity messages. Young Italian women were exposed to one of three experimental conditions showing sexualized beauty ideals, sexualized body positivity, or non-sexualized body positivity that appeared either on Instagram (Study 1, N = 356) or TikTok (Study 2, N = 316). Across the two studies, results showed that, regardless of sexualization, exposure to body positivity increased body satisfaction and positive mood compared with pre-exposure measures, while exposure to sexualized beauty ideals reduced it. Participants in the sexualized beauty ideal condition also engaged in upward appearance social comparison whereas body positivity elicited downward comparison. Problematic social networking sites' use moderated the effects of condition on body satisfaction, appearance social comparison, and positive mood, while downward comparison mediated the relation between condition and body satisfaction and positive mood. Our results highlight both beneficial and critical aspects of body positivity that should be taken into consideration when designing body image interventions and policymaking.

RESUMO

BACKGROUND: Given the heightened emphasis on physical appearance and the prevalence of social media in young women, they are particularly vulnerable to experiencing negative body image and disordered eating. Therefore, modified social media portrayals of pregnancy could cause young women to have negative attitudes toward a potential pregnancy and subsequently not properly utilize care and resources. The present study examined the influence of disordered eating and modified portrayals of pregnancy on young women's attitudes toward a potential pregnancy and various feelings associated with pregnancy. METHODS: The sample consisted of 154 women aged 18-30, who were given the Eating-Attitudes Test-26, randomly shown either modified or unmodified social media portrayals of pregnancy, then given the Attitudes Toward Potential Pregnancy Scale and the Gestational Weight Gain Psychosocial Risk Assessment Tool. RESULTS: A series of hierarchal regressions revealed that there were no significant main effects or interactions for young women's attitudes toward potential pregnancy. However, women who viewed modified portrayals of pregnancy had higher self-efficacy, and women with higher levels of disordered eating had lower self-efficacy, more positive attitudes toward gestational weight gain, and lower current body image satisfaction. CONCLUSIONS: These results highlight the myriad of different attitudes that young women have toward a potential pregnancy and how these attitudes are influenced by disordered eating and social media. Our findings can be used for educating caregivers and implementing intervention strategies for women.


Young women are more likely to have a negative body image and an unhealthy relationship with food because they are more focused on their physical appearance, especially with the rise of social media. If young women with these struggles see edited representations of pregnancy, they can develop a negative attitude about becoming pregnant in the future. This study examined how unhealthy eating habits and highly edited pictures of pregnant women impact young women's attitudes toward a potential pregnancy. Our participants answered questions designed to see if they possess unhealthy eating thoughts and behaviors, then they were randomly shown either highly edited or not highly edited pictures of pregnant women from social media. Then, they answered questions about their attitude toward a potential pregnancy. We found that women with particularly unhealthy relationships with food were less confident about maintaining healthy eating habits throughout pregnancy. However, we also found that women who viewed the highly edited pictures were more confident about maintaining healthy eating habits throughout pregnancy. We can use these results to educate caregivers and help women get better care.

RESUMO

This study investigated a novel technique to improve body image among women who have undergone bariatric surgery-namely, by having them focus on their body functionality (everything the body can do, rather than how it looks). Participants were 103 women (Mage = 46.61) who had undergone bariatric surgery 5-7 months prior to the study. They were randomized to the 1-week online intervention, comprising three functionality-focused writing exercises (Expand Your Horizon; Alleva et al., 2015), or to a wait-list control group. Body appreciation, appearance and functionality satisfaction, body awareness, self-objectification, self-esteem, and self-kindness were assessed at pretest, posttest, and at 1-week and 3-month follow-up. Multilevel modeling analyses showed that, compared to the control, the intervention group experienced improved body appreciation at posttest, and these improvements persisted at both follow-ups. These findings were nonsignificant when intent-to-treat analyses were performed. Both available case and intent-to-treat analyses showed that all participants experienced improvements in facets of body image across time. Qualitative analyses of participants' responses to the intervention writing exercises provided more insight. Via coding reliability thematic analysis, we identified 11 themes that together provide evidence that intervention participants experienced facets of a more positive body image, while also facing challenges to their body image and well-being. Together, findings suggest that focusing on body functionality may contribute to improved body image among women who have undergone bariatric surgery, but effects may be nuanced compared to prior functionality research among general samples of women. The study was registered retrospectively (ClinicalTrials.gov; identifier NCT04883268).

RESUMO

BACKGROUND: Both depression and anxiety are worldwide burden that is not being abated with our current knowledge and treatment of the condition. Numerous clinical trials have supported that physical activity (PA) can reduce the depression and anxiety in adolescents, but little is known about its mechanism of action. Therefore, the study objectives were to explore the potential relationship between physical activity and depression and anxiety from the perspective of body image and body mass index (BMI), and to provide an important reference for future self-esteem education and health promotion intervention. METHODS: The participants in this study were 251 Chinese college students between 17 and 22 years old. Participants completed the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Body Image Questionnaire (BIQ), the Self-rating Depression Scale (SDS) and the Self-rating Anxiety Scale (SAS). A descriptive and correlational approach was used, using the PROCESS macro for Statistical Package for the Social Sciences (SPSS). RESULTS: (1) Physical activity was significantly negatively correlated with both depression and anxiety (t = -0.216, p < 0.001; t = -0.184, p < 0.01). (2) Body image had a significant moderating effect on the relationship between physical activity and anxiety among college students, but there was no moderating effect between depression and physical activity. BMI has no moderating effect on the two interrelationships. CONCLUSION: There is only body image that moderates the relationship between anxiety and physical activity.

RESUMO

En un contexto de incertidumbre, estrés, incorporación de tecnología y procesos formativos híbridos se requiere de alternativas innovadoras sencillas y eficientes con posibilidades de mejorar la actuación y compromiso académico de los estudiantes en los procesos de enseñanza-aprendizaje del área de Educación Física (EF). El estudio tuvo por objetivo determinar el efecto de la sofropedagogía como estrategia de regulación motivacional para el aprendizaje de capacidades referidas al desarrollo de conciencia del esquema corporal y activación mental positiva en el área curricular de EF. Es una investigación cuasiexperimental con pre y post prueba sin grupo control, desarrollada en procesos formativos presenciales y no presenciales durante dos semestres académicos, con 150 estudiantes del ciclo inicial, intermedio y superior de la Escuela Profesional de Educación Física/Universidad Nacional del Altiplano, Puno-Perú. Los resultados destacan la factibilidad de incluir la sofropedagogía como un entrenamiento motivacional-inductor en los procesos formativos híbridos de enseñanza-aprendizaje, cuyos efectos en el aprendizaje de capacidades en EF fueron significativos: 0.000 menor a 0.05 según la prueba de rangos con signo de Wilconxon. Se concluye que la sofropedagogía ha mostrado otorgar opciones de autonomía-flexibilidad para planificar, ejecutar y monitorear acciones en relación a objetivos propuestos en el área de EF y se adapta fácilmente a calendarios, espacios y ritmos de aprendizaje individual-colectivo de los estudiantes de EF.

RESUMO

The Sense of Ownership (SoO) and the Sense of Agency (SoA) are two key components of bodily self-consciousness. In this experiment, we investigated how they are affected by variations in the ecological validity of the moving Rubber Hand Illusion (mRHI) paradigm, which typically include three movement conditions: active congruent, passive congruent, and active incongruent. These conditions were either in a session in which no auditory feedback associated with finger-tapping was eliminated, or in a session in which such a feedback occurred. Since the presence of the auditory feedback more closely corresponds to what individuals experience in daily life when they tap their finger on a surface, sessions with feedback are more ecologically valid, and should thus result in a more marked SoO. Results indicated that in the active movement condition in which the illusion is typically found (congruent), the effect was enhanced when the feedback was present. This advantage emerged on both on objective and subjective measures of SoO. The SoA, on the other hand, is not affected by the auditory feedback.

RESUMO

The aim of this study was to determine the prevalence of orthorexia nervosa (ON) among professional dancers in Greece, as well as its relationship with nutrition, body mass index (BMI), body image flexibility, and parental bonding. The participants were 96 professional dancers, with a mean age of 23.41 ± 5.13 years, who completed a battery of questionnaires recording sociodemographic, clinical, and anthropometric characteristics; adherence to the Mediterranean diet (MedDiet); indications of ON, as determined by the ORTHO-15 questionnaire; body image flexibility, using the body image-acceptance and action questionnaire (BI-AAQ-5); and their recollection of their parents' attitudes towards them during the first 16 years of life, with the parental bonding instrument (PBI). The study population was classified into two groups, based on BMI: normal weight, and underweight. ON was shown to be significantly correlated with BMI (p = 0.006)-present in normal weight subjects- and body image inflexibility (p < 0.001). Parental body image inflexibility was significantly correlated with a low bonding relationship as perceived in childhood. In conclusion, disordered eating attitudes and body shape concerns are prevalent among professional dancers and appear to be associated with their parental relationship during childhood. Identification of potential ON and development of preventive mechanisms could help to eliminate such concerns and improve the nutrition of professional dancers.

RESUMO

OBJECTIVE: To assess secular trends in body image dissatisfaction and associated factors among adolescents over a 10-year period (2007-2017/2018). METHODS: The sample included 1,479 (2007, n = 531; 2017/2018, n = 948) high school adolescents of both sexes, aged 14 to 18 years, of schools in a city in southern Brazil, in 2007 and 2017/2018. Data were collected on sex, age, physical activity (IPAQ, short form), anthropometric measurements (body weight, height, and triceps and subscapular skinfolds), and body image dissatisfaction (figure rating scale). The variables were compared with Independent samples t-test and Mann-Whitney U-test. The associations between sex and other variables were examined with chi-square test, and the factors associated with body image were identified with multinomial logistic regression. RESULTS: Most adolescents were dissatisfied with their body image in 2007 (65,2%) and 2017/2018 (71,1%). The prevalence of body dissatisfaction increased by 9.2% over the 10-year period, particularly dissatisfaction with thinness (21.3%). After stratification by sex, in 2017/2018 sample, dissatisfaction with overweight was 46.1% greater in boys, and dissatisfaction with thinness was 66.9% greater in girls. Factors found to be significantly associated with body image dissatisfaction were physical activity level, and body adiposity. CONCLUSIONS: There was a secular trend toward increased body image dissatisfaction in both sexes. Future efforts should go beyond scientific production, in public and private environments aimed at increasing awareness of health issues related to body care in the physical, psychological, and environmental domains.

RESUMO

BACKGROUND AND AIM: The objective was to decrease patient menopausal symptoms, sleep disturbance, and body image using a nonpharmacological therapy for cultivating key healthy lifestyle habits in patients with breast cancer. MATERIALS AND METHODS: The participants were 26 women with breast cancer who had recently received structured mindfulness-based stress reduction (MBSR) training in a clinical trial. Focus groups and interviews were conducted, during which the participants were asked semistructured, open-ended questions regarding the experiences of MBSR. RESULTS: The participants indicated that MBSR helped them to alleviate hot flashes and night sweats, and improve sleep quality and be more at ease with the external aspect of their body. On the other hand, during MBSR intervention in a group manner, the participants felt more psychological support and an outlet for sharing negative emotional experiences. CONCLUSION: This study identified the short-term benefits associated with group-based MBSR for women with breast cancer. In addition, our research identified the difficulties of intervention measures and coping methods. The study described the benefits of MBSR for patients with breast cancer. The findings of this study will help nursing staff identify the main coping menopausal symptoms and control negative mental health.

RESUMO

Purpose Body image encompasses body-related self-perceptions and personal attitudes. Dissatisfaction with body image during the early stages of adolescence is negatively related to self-esteem and other health problems. A few publications focused on positive body image and directly related to the experiences and interactions of adolescents themselves. To explore positive body image in adolescents and describe the familial and educational factors that contribute to its development.Methods A qualitative study was conducted. Purposive sampling was used, and 9 adolescents, 6 families, and 8 teachers participated in semi-structured interviews, which were then theme analyzed. Results Self-care, body acceptance, confronting messages that attack body image, and the influence of social media have been identified as emerging themes in adolescents' positive body image experiences. Therefore, the pubertal period, family values, fostering, and educational actions as well as media literacy were identified as factors promoting self-esteem and positive body image in the family and educational environment. Conclusions Their parents also expressed aspects such as those that contribute to the development of healthy self-esteem, confidence, and positive body image. Alternatively, the teachers indicated educational activities to work on self-image and self-esteem when faced with situations of concern in the classroom.

RESUMO

OBJECTIVE: To translate the cancer-specific Body Image Scale (BIS) into German and assess its psychometric properties. METHODS: The BIS was translated in accordance with current guidelines. In a prospective, cross-sectional two center study (psychosocial counselling center for cancer patients Leipzig, oncological inpatient ward Berlin), we assessed composite reliability and factor structure using confirmatory factor analysis. Additional item response theory (IRT) modelling was performed. Convergent validity was assessed via correlation with the Body Appreciation Scale (BAS) as well as psychological symptom burden (PHQ-9, GAD-2 and Distress Thermometer). Discriminant validity was assessed via demographic and clinical group comparisons. RESULTS: 677 patients participated (response rate 78%). Composite reliability was 0.95 and the one-factor structure was confirmed (standardized root mean square residual = 0.051, average variance extracted ≥50%, no indications of local dependence). In IRT models, all items had a discriminating power above the established threshold of b = 0.5 and relatively high "difficulty" parameters (b = 0.89-2.06). The BIS was negatively correlated with the BAS (rho = -0.62, p < 0.001) and positively with psychological symptom burden (e.g. PHQ-9: rho = 0.49, p < 0.001). Patients who were younger, female, had undergone chemotherapy, radiotherapy or surgery and those who were distressed by fatigue, their appearance or sexual problems had significantly higher BIS scores. CONCLUSION: The German version of the BIS is a valid tool to assess BID in patients with cancer that is now available for clinical or research contexts.

RESUMO

Part of the multifaceted pathophysiology of Complex Regional Pain Syndrome (CRPS) is ascribed to lateralized maladaptive neuroplasticity in sensorimotor cortices, corroborated by behavioral studies indicating that patients present difficulties in mentally representing their painful limb. Such difficulties are widely measured with hand laterality judgment tasks (HLT), which are also used in the rehabilitation of CRPS to activate motor imagery and restore the cortical representation of the painful limb. The potential of these tasks to elicit motor imagery is critical to their use in therapy, yet, the influence of the body's biomechanical constraints (BMC) on HLT reaction time, supposed to index motor imagery activation, is rarely verified. Here we investigated the influence of BMC on the perception of hand postures and movements in upper-limb CRPS. Patients were slower than controls in judging hand laterality, whether or not stimuli corresponded to their painful hand. Reaction time patterns reflecting BMC were mostly absent in CRPS and controls. A second experiment therefore directly investigated the influence of implicit knowledge of BMC on hand movement judgments. Participants judged the perceived path of movement between two depicted hand positions, with only one of two proposed paths that was biomechanically plausible. While the controls mostly chose the biomechanically plausible path, patients did not. These findings show non-lateralized body representation impairments in CRPS, possibly related to difficulties in using correct knowledge of the body's biomechanics. Importantly, they demonstrate the challenge of reliably measuring motor imagery with the HLT, which has important implications for the rehabilitation with these tasks.

RESUMO

Body image is a construct of the multifaceted representation of body identity that involves self-perception, beliefs, attitudes about the body itself, which can be influenced by several factors. This study evaluated the association of body image with anthropometric and lifestyle indicators among adolescents. The sample comprised 465 adolescents aged 10 to 17 years from public schools in the city of Salvador-Bahia. The Silhouettes Scale assessed the body image. The anthropometric data (body mass index and waist circumference), the lifestyle (Physical Activity Questionnaire for Adolescents and television time), economic and demographic data were evaluated. Polytomous logistic regression assessed associations of interest by STATA, version 16.0. Overweight (OR:9,7; CI95%:5,4-17,5) and abdominal obesity (OR:14,0; CI95%: 5,0-39,3) were positively associated with body dissatisfaction. However, there was no association with lifestyle variables (physical activity: OR: 1,7, CI: 0,9-2,9, and TV time: OR:1,2; CI:0,8-1,9). The conclusion reached is that anthropometric status is an essential indicator of adverse body image outcomes in adolescents.


A imagem corporal é um constructo da representação multifacetada da identidade corporal, envolve autopercepção, crenças e atitudes sobre o próprio corpo, podendo ser influenciada por diversos fatores. Este estudo avaliou a associação da imagem corporal com indicadores antropométricos e do estilo de vida em adolescentes. Constituíram a amostra 465 adolescentes de 10 a 17 anos de escolas públicas da cidade de Salvador, na Bahia. A imagem corporal foi avaliada pela Escala de Silhuetas. Os dados antropométricos (índice de massa corporal e a circunferência da cintura), de estilo de vida (Physical Activity Questionnaire for Adolescents e o tempo de televisão), econômicos e demográficos foram avaliados. Regressão logística politômica avaliou as associações de interesse. Os dados foram analisados pelo software STATA, versão 16.0. O sobrepeso/obesidade (OR: 9,7; IC95%: 5,4-17,5) e a obesidade abdominal (OR: 14,0; IC95%: 5,0-39,3) se mostraram positivamente associados à insatisfação corporal, mas não foi observada associação com as variáveis de estilo de vida (atividade física: OR: 1,7; IC95%: 0,9-2,9; e tempo de TV: OR: 1,2; IC95%: 0,8-1,9). Conclui-se que o estado antropométrico é um importante indicador dos desfechos negativos da imagem corporal em adolescentes.

RESUMO

The aim was to investigate the relationship between lower extremity lymphedema and pelvic floor functions, sleep quality, kinesiophobia, body image in patients with gynecological cancer the effect of lymphedema severity on pelvic floor dysfunction (PFD), sleep quality, fear of movement, and body image in patients with lower extremity lymphedema after gynecologic cancer. A total of 103 patients (52 patients with lymphedema and 51 patients without lymphedema) after gynecologic cancer surgery were included in March-June 2022. Bilateral circumferential measurements were taken with a tape measure at different levels to create groups. These measurements determined limb volumes by summing segment volumes derived from the truncated cone formula. For data collection, all patients were presented with the Gynecologic Cancer Lymphedema Questionnaire (GCLQ), the Global Pelvic Floor Bother Questionnaire (GPFBQ), the Pittsburgh Sleep Quality Index (PSQI), the Tampa Scale of Kinesiophobia (TSK) and the Body Image Scale (BIS) one time. The severity of lymphedema symptoms was quite high in patients with lymphedema (GCLQ Total: 13.6) (p < .05). Patients with lymphedema had higher GCLQ total scores, GPFBQ1 (stress urinary incontinence), GPFBQ4 (urge urinary incontinence), GPFBQ8 (fecal incontinence), kinesiophobia and, body image scores than patients without lymphedema (p < .05). The sleep quality levels of patients with lymphedema and patients without lymphedema were similar (p > .05). A significant negative correlation was found between GLCQ total score and body image (p < .05). There was a positive correlation between kinesiophobia and pelvic floor symptoms and a negative correlation between kinesiophobia and body image (p < .05). In this study, it was observed that in patients who developed lymphedema after gynecologic cancer surgery, pelvic floor symptoms and kinesiophobia increased and the severity of lymphedema negatively affected body image. Reducing lymphedema in these patients may improve pelvic floor health, mobility, and body image.

RESUMO

OBJECTIVE: Individuals who are preoccupied with food are more likely to develop maladaptive eating behaviours and eating disorders. Thus, it is advisable to investigate the factors that increase vulnerability to food preoccupation (FP) to prevent its harmful impact on physical and mental health. Our objective in this study was to investigate the relationship between body mass index (BMI) and FP in Polish women (N = 407) and examine a possible pathway through body-related shame and body-related guilt and self-esteem. METHOD: Participants completed an abbreviated version of the Eating Attitudes Test-26, the Body and Appearance Self-Conscious Emotions Scale, and the Rosenberg Self-Esteem Scale. RESULTS: The findings demonstrated a positive indirect effect of BMI on FP through body-related shame and body-related guilt. However, this effect was moderated by self-esteem only for body-related shame; namely, in women with a low or average level of self-esteem, higher BMI was related to higher body-related shame, which, in turn, was associated with higher levels of FP. These associations were not observed in women with a high level of self-esteem. DISCUSSION: Body-related shame may help explain the relationship between BMI and FP. Moreover, self-esteem serves as a protective factor against body-related shame related to higher BMI and, as a result, against FP.

RESUMO

Emerging evidence highlights the intricate link between identity and one's body, however, integrative longitudinal research on this identity-body interplay is lacking. The current study used three-wave longitudinal data (Time 1: N = 403; 52.1% female; Mage = 14.85, SD = 0.89, range = 13-19 years) spanning two years (2019-2021; T1 and T2 being pre-pandemic, T3 peri-pandemic) to identify identity trajectory classes and examine their co-development with negative and positive body image and various body-related variables (i.e., sociocultural pressures, internalization of appearance ideals, self-objectification, appearance comparison, and eating disorder symptoms). First, four identity classes emerged using latent class growth analysis (achievement, moratorium, carefree diffusion, and troubled diffusion). Second, using multigroup latent growth curve modeling, adolescents in less adaptive identity trajectory classes (i.e., engaging less in pro-active processes and more in ruminative processes) displayed higher levels of negative body image and body-related symptoms. The current study testified to the clinically meaningful associations linking identity formation to adolescents' body image and other body-related symptoms.
