RESUMO

BACKGROUND: Due to the prevalence and associated adverse health consequences of negative body image among adolescents globally, there is a need to develop acceptable, effective, and scalable interventions. School-based body image interventions delivered by trained teachers show promise in reducing negative body image in adolescents. However, there is currently a lack of evidenced-based body image interventions for use in low- and middle-income countries (LMICs). This paper outlines a protocol for the development and evaluation of Dove Confident Me Indonesia: Single Session, a single-session, teacher-led body image intervention for Indonesian adolescents. METHOD: The effectiveness of the intervention will be evaluated using a cluster randomised controlled trial design. Due to the COVID-19 pandemic, the trial will be conducted online. Trained teachers or school guidance counsellors will deliver the intervention. Self-report questionnaires will be collected at three time points: baseline, post-intervention, and two-month follow-up. The primary outcome is body esteem. Secondary outcomes are internalisation of appearance ideals, mood, engagement in life activities, tendency to engage in appearance comparisons, and skin shade satisfaction. A minimum of 1000 participants will provide 95% power to detect small-to-medium intervention effects. To account for attrition and potential internet issues, the sample will comprise of 2000 Indonesian adolescents in grades 7-9, attending state junior high schools in Surabaya, East Java. Quantitative and qualitative data on acceptability of the intervention will also be collected from teachers and students. Additionally, fidelity of lesson implementation will be assessed. This project received ethical approval from the Universitas Indonesia and the University of the West of England. The intervention will be disseminated in junior high schools throughout Indonesia via UNICEF's Life Skills Education (LSE) programme, which will be freely available for teachers to download. DISCUSSION: This paper presents Dove Confident Me Indonesia: Single Session, a culturally adapted school-based intervention designed to improve Indonesian adolescents' body image. It details the plan for evaluation, highlighting the strengths and limitations of the proposed study design. It will be informative for others aiming to adapt evidence-based school curricula to promote well-being among adolescents in LMICs. TRIAL REGISTRATION: NCT04665557 . Registered 11th December 2020.

RESUMO

Research on eating disorders (EDs) and body image disturbances has focused mostly on females from Western countries, and little is known about EDs in male populations in China, which is partially due to the lack of validated assessment measures. The current work aims to translate the Muscularity-Oriented Eating Test (MOET), Drive for Muscularity Scale (DMS) and Muscle Dysmorphic Disorder Inventory (MDDI) into Chinese and examine their psychometric properties. The factor structures, reliability and validity of the translated scales were examined with two samples: male university students (n = 295, Mage = 18.92 years) and general adult men (n = 406, Mage = 28.53 years). With confirmatory factor analyses, the original factor structures are replicated for the MOET, DMS and MDDI. The results also support the adequate internal consistency for both samples. Strong evidence of convergent and incremental validity for the three measures is also found in both samples. Overall, the three measures prove to be good instruments for use among Chinese male university students and general adult men.

RESUMO

Obesity has become a serious public health problem worldwide and is linked to an increased risk of non-communicable diseases (NCDs). Poor self-perception of body weight is postulated to play a negative role in curbing increased rates of obesity. This study investigated the views of own body weight and perceived risk of developing NCDs in South African adults. This was a community-based quantitative study. Descriptive statistics were used, and logistic regression analysis was conducted on the data. A total of 1050 respondents took part in the study. Of the 161 respondents who perceived themselves to be normal weight, 98.8% (n = 159) misperceived their body weight. The majority of respondents (>90%) who were overweight according to the calculated BMI perceived no risk of developing obesity-related diseases. Most of the respondents, 46% (n = 253), believed that body weight was influenced by heredity. The method used for weight loss by 57% (n = 173) of the respondents was exercising at home. There was a statistically significant association between Body Mass Index (BMI), employment status, risk of developing diabetes, and body weight misperception (p < 0.05). Misperception of body weight was common among the study respondents and may influence weight control intervention strategies. Health promotion targeting personal behaviour, such as body weight self-perception, is crucial in supporting targeted strategies to address obesity in South Africa.

RESUMO

Large surveys indicate that many people perceive that their health behaviors (i.e., eating behaviors, physical activity, and self-care routines) and body image have changed during COVID-19; however, large individual variation exists. A person's cognitive appraisal of COVID-19 disruptions may help account for individual differences. Those with a negative problem orientation perceive problems as "threats", whereas those with a positive problem orientation reframe problems as "opportunities". The present experimental study examined the impact of appraisals, specifically being prompted to reflect on the changes in health routines precipitated by COVID-19 restrictions as either "threats" or "opportunities", on problem orientation, coping behaviours, body image, and perceptions of eating behaviors and physical activity in a sample of female undergraduate students (N = 363). The group that reflected on challenges/barriers reported having a more negative problem orientation, being more negatively impacted by COVID-19, engaging in more maladaptive coping behaviors, and having less positive body image compared to participants who reflected on opportunities presented during the pandemic. Findings suggest that appraisals and problem orientation are malleable, and that people who tend to fixate on the challenges associated with COVID-19 may benefit from strategically reflecting on their own resilience and new opportunities that have arisen for engaging in health behaviors.

RESUMO

The 10-item Body Appreciation Scale-2 (BAS-2) is a measurement for individuals to self-report the extent to which they accept and respect their bodies. Although the BAS-2 has been translated into the Malay language and found to have promising qualities, the psychometric characteristics of the English version of BAS-2 remain unknown in the Malaysian context. The present study thus administered the English version BAS-2 and selfie-editing frequency scale to 797 individuals aged 18 to 56 years old in Malaysia. The dataset that was randomly divided into two halves were submitted to exploratory factor analysis and confirmatory factor analysis respectively. Both of the factor analyses consistently support a one-factor model. The Cronbach's alpha and McDonald omega coefficients were greater than 0.90, indicating that the BAS-2 has good internal consistency. The incremental validity is also evident. A hierarchical multiple regression showed that the BAS-2 score had a positive relationship with selfie-editing frequency after controlling for age and gender. Moreover, the measurement invariance test supported scalar invariance between genders, and an analysis of covariance did not find significant gender differences. Overall, the findings replicate past findings and regularly support the usability of the BAS-2 in the Malaysian context. The implications of the BAS-2 and future directions are also discussed.

RESUMO

This study investigated the perception of above ideal body weight among adolescents in the city of Recife, Brazil, and its association with anthropometric profile and lifestyle. A cross-sectional study was conducted with a sample of 2480 adolescents from the "Study of Cardiovascular Risks in Adolescents." The conceptual model also assessed demographic and socioeconomic variables. Body weight perception was analyzed by asking the question: "In your opinion, your current body weight is … ?" Answers included: below ideal, ideal and above ideal body weight. Statistics were identified using Poisson Regression analysis. The mean age was 14.7 years (SD = 1.6), 53.7% were female, and 70.7% were eutrophic according to the body mass index/age (BMI/A). Perception of body weight was answered by 48.8% of the adolescents. 36.8% and 63.2% saw themselves as below and above their ideal weight, respectively. After adjustments, the variables associated with the perception of body weight above the ideal (outcome variable) were the female sex, age 12 to 14 years, mother's schooling > 8 years, BMI/A in the ideal range, being postpubescent, having breakfast and meals with parents occasionally. Demographic, anthropometric and lifestyle variables were more likely to be associated with body weight perception above the ideal.

RESUMO

PURPOSE: This study's objective was to investigate the effects of programs that improve adolescents' body image, using a systematic review and meta-analysis. METHODS: A literature search was performed in eleven electronic databases, using preferred reporting items for systematic reviews and meta-analysis guidelines. Population characteristics, contents of the programs, and measured outcomes were systematically reviewed from 21 selected studies. To estimate the size of the effects, meta-analysis was conducted using Comprehensive Meta-Analysis software. RESULTS: The contents of the programs that aimed to improve body image included physical, psychological, interpersonal, and sociocultural interventions. Sixteen studies were meta-analyzed to estimate the effect size of body-image improvement programs. Results showed that the program for body-image improvement had significant effects on body satisfaction (effect size [ES] = 0.56, 95% confidence interval [CI] = 0.23 to 0.89), and body dissatisfaction (ES = - 0.15, 95% CI = - 0.23 to - 0.08). CONCLUSION: The program for body image improvement in adolescents includes a combination of physical, psychological, interpersonal relationship, and socio-cultural dimensions. The program that seeks to improve body image appears to be effective at increasing body satisfaction, and at reducing body dissatisfaction in adolescents. Thus, it is necessary to develop and apply multidimensional programs for adolescents to have a positive body image.

RESUMO

Melanoma is one of the most lethal and rapidly growing cancers, causing many deaths each year. This cancer can be treated effectively if it is detected quickly. For this reason, many algorithms and systems have been developed to support automatic or semiautomatic detection of neoplastic skin lesions based on the analysis of optical images of individual moles. Recently, full-body systems have gained attention because they enable the analysis of the patient's entire body based on a set of photos. This paper presents a prototype of such a system, focusing mainly on assessing the effectiveness of algorithms developed for the detection and segmentation of lesions. Three detection algorithms (and their fusion) were analyzed, one implementing deep learning methods and two classic approaches, using local brightness distribution and a correlation method. For fusion of algorithms, detection sensitivity = 0.95 and precision = 0.94 were obtained. Moreover, the values of the selected geometric parameters of segmented lesions were calculated and compared for all algorithms. The obtained results showed a high accuracy of the evaluated parameters (error of area estimation <10%), especially for lesions with dimensions greater than 3 mm, which are the most suspected of being neoplastic lesions.

RESUMO

As the object of care in medical treatment, the body is apprehended and invested in by patients from the point of view of the subject. The social, cultural and historical background of the subjects shapes their relationship with their body and regulates the possible impact of its transformations. These elements are important to take into account in the identification of body image disturbances and access to dedicated care. The experience of carers in dealing with these "marked" bodies must also be taken into account.

RESUMO

The confrontation with the diagnosis of cancer and its treatment leads to an experience of fragmentation. Working in a multidisciplinary manner enables the patient to be accompanied in the phase of reappropriating a body schema modified by surgery. In this context, socio-aesthetics offers the patient the possibility of regaining harmony between body and mind, with a view to improving the quality of life during and after treatment. Crossed views based on the testimony of a patient.

RESUMO

Chronic illnesses, such as diabetes, have an impact on the body, but also on the psyche, disturbing the body image of the child or adolescent. This must be integrated into their"growing up process". To this end, health care professionals specialising in these populations provide the most appropriate support during these periods of doubt and uncertainty.

RESUMO

Background and Objectives: It is well known that among all cancers, cancers of the head and neck (HNC) have a major impact on patients' quality of life. Disfigurement, anxiety and disabling physical and psychological symptoms affect people with HNC to such an extent that the suicide rate in this category of patients is exceeded only by that of patients with pancreatic cancer. The aim of this review was to summarize the published literature describing the severity of body image and quality of life impairment in patients with HNC over time, and to examine the psychosocial and functional associations and interventions implemented to improve body image and quality of life. Materials and Methods: We conducted a literature search from 1 January 2018 to June 2021 that included electronic searches of six major databases (PubMed, ScienceDirect, ProQuest, PsycINFO, PsychArticles and Scopus) and review of references of articles screened. Of 620 records, only 9 articles met the eligibility criteria. Results: Numerous studies have been conducted to analyze various psychological variables, but there is still a lack of standardization in the assessment of body image perception (BI) and quality of life, resulting in small-scale testing of interventions with poor results. Conclusions: Expected longitudinal studies describing the flow of body image problems and the mediation and balance factors associated with body image will allow researchers to design methods aimed at limiting body image disorders and thus improving quality of life of patients with head and neck cancer.

RESUMO

Improving our understanding of what physical activities are enjoyed and the factors that are associated with physical activity liking can promote participation in regular physical activity. We aimed to study physical activity (PA) liking in college women by modelling interactions between body size perception and dietary behaviors on PA liking, and by examining discrepancies between PA liking versus engagement on body size perception and dietary behaviors. Women (n = 251; 74% white) utilized an online survey to report their level of liking for PA types (scored into a PA liking index) and frequency of PA participation. They also reported their perceived body size, level of dietary restraint, and frequency of consuming foods (scored into a diet quality index). In multivariate analyses, a greater perceived body size was directly associated with lower PA liking and indirectly through greater dietary restraint but lower diet quality. Healthiest dietary behaviors were reported by women who both liked and engaged in PA. Women who reported high PA liking but low PA participation reported a higher dietary restraint and lower diet quality. These findings support the empowerment of women across all body sizes to identify physical activities that they enjoy. Health promotion efforts should encourage women to couple physical activity liking and engagement with a healthy level of dietary restraint and consumption of a healthy diet.

RESUMO

BACKGROUND: Fitness inspiration or fitspiration is a term used to describe web-based images of fit people, people in the gym, health foods, or inspirational quotes relating to diet and fitness being shared and consumed via visual social media. The popularity of this content is most notable via the Instagram platform. Currently, the majority of fitspiration research has focused on women's experiences; however, increasingly, studies have pointed to the need to explore the gendered ways by which people engage with this content. OBJECTIVE: The aim of this study is to explore how young men and women engage in fitspiration content on Instagram and provide a gendered analysis of how and why they consume this content. METHODS: This study used a cross-sectional web-based survey (N=1213) of UK-based fitspiration users aged 18-24 years consisting of closed-ended questions to capture quantitative data. RESULTS: The majority actively using Instagram for fitspiration (therefore eligible participants) were women (826/1175, 70.30%). Men were more likely to view content posted by athletes (χ21, N=1153=71.8; P=.001) and bodybuilders (χ21, N=1153=32.8; P<.001), whereas women were more likely to view content related to weight loss (χ21, N=1153=36.8; P<.001), diet plans (χ21, N=1153=11.9; P<.001), and celebrities' content (χ21, N=1153=33.5; P<.001). Men were more likely to use fitspiration as a source of inspiration to exercise to gain muscle or get stronger (χ21, N=1147=17.9; P<.001), whereas women were more likely to use fitspiration as inspiration for healthy eating (χ21, N=1147=37.7; P<.001), or to exercise to diet or lose weight (χ21, N=1147=13.5; P<.001). Women were more likely to engage in passive behaviors such as viewing content on their feed (χ21, N=1139=7.9; P=.005) or scrolling through accounts (χ21, N=1139=15.2; P<.001), whereas men were more likely to engage in active consumption by tagging fitspiration accounts in posts (χ21, N=1139=7.2; P=.007), commenting on posts (χ21, N=1139=8.1; P=.004), and posting fitspiration content (χ21, N=1139=6.4; P=.01). CONCLUSIONS: Female fitspiration consumers engaged with content that reinforced the feminine thin but shapely ideal, whereas male users sought out content that reinforced the masculine muscular ideal. Male users were more likely to engage actively with content (eg, posting fitspiration content), while female users were more likely to engage passively (eg, scrolling through accounts, posts, or images). Future research should consider how fitspiration consumption reflects and reproduces oppressive gender ideology.

RESUMO

Autism is a neurodevelopmental disorder characterized by impaired social skills, motor and perceptual atypicalities. These difficulties were explained within the Bayesian framework as either reflecting oversensitivity to prediction errors or - just the opposite - slow updating of such errors. To test these opposing theories, we administer paced finger-tapping, a synchronization task that requires use of recent sensory information for fast error-correction. We use computational modelling to disentangle the contributions of error-correction from that of noise in keeping temporal intervals, and in executing motor responses. To assess the specificity of tapping characteristics to autism, we compare performance to both neurotypical individuals and individuals with dyslexia. Only the autism group shows poor sensorimotor synchronization. Trial-by-trial modelling reveals typical noise levels in interval representations and motor responses. However, rate of error correction is reduced in autism, impeding synchronization ability. These results provide evidence for slow updating of internal representations in autism.

RESUMO

BACKGROUND: Body image concerns have been widely documented in the literature as one reason why most women shorten the breastfeeding duration of their infants. Negative body image concerns among breastfeeding mothers may lead to depressive symptoms. There is a paucity of literature on how body image affects the breastfeeding practices of nurses and midwives. Therefore, this study explored the perspectives of breastfeeding nurses and midwives on how their body image affected their breastfeeding practices. METHODS: A qualitative design was used in this study. Five focus group discussions were conducted with each group having five members. The study was conducted in the Greater Accra Region of Ghana between November and December of 2020. Participants were recruited into the study using a purposive sampling method. Focus group sessions were audiotaped and transcribed verbatim. Data were analyzed using a content analysis. RESULTS: Three main themes emerged from the data analysis: body image concerns and breastfeeding, sociocultural pressures and breastfeeding and coping strategies. Participants had concerns regarding weight gain due to the need to eat adequately while breastfeeding. Body image concerns included increase in abdominal size, sagging breasts and generalized weight gain. These concerns and pressures negatively affected the breastfeeding practices of participants. Body image concerns reflected sociocultural pressures such as negative comments from loved ones and in the social media. The coping strategies adopted by the mothers were self-motivation and the love they had for their children. CONCLUSIONS: The perspectives of breastfeeding nurses and midwives on the ways their body image affected their breastfeeding practices identified the need for support in order to successfully breastfeed.

RESUMO

Objective: A relative can be an asset in dealing with chronic illnesses, such as acromegaly, where quality of life (QoL) is altered even after remission. However, it has been shown that quality of life of caregivers can also be impacted. Our main objective was to compare the perception of acromegaly in remission in the patient-relative dyad. Methods: In this observational study, 27 patients in remission and relatives were first asked to complete QoL, anxiety/depression and coping strategy questionnaires. Then, the patient's body image and self-esteem were evaluated from both the patient's and the relative's point of view using the same questionnaires with modified instructions. Results: Relatives had overall an accurate estimation of patient body image using the Figure Rating Scale by Stunkard. However, there were wide variations between the patient's and the relative's responses regarding self-esteem and body perception. The QoL of relatives was not altered and was significantly higher in the social domain than for the patient. Conclusions: Our results show that relatives require education concerning all the steps involved in the management of acromegaly, as they likely do not fully understand the sequelae of acromegaly.

RESUMO

BACKGROUND: Although no severity specifiers are noted in the Diagnostic and Statistical Manual of Mental Disorders - 5 for other specified feeding or eating disorder (OSFED), shape/weight overvaluation is a proposed eating disorder (ED) severity specifier. We used structural equation modeling (SEM) Trees to empirically determine values of shape/weight overvaluation that differentiate OSFED severity. We additionally tested whether the SEM Tree-defined thresholds or a clinical cutoff for shape/weight overvaluation differentiated severity more meaningfully. METHODS: Participants were 690 females with OSFED presenting to residential ED treatment. SEM Tree analyses specified an outcome model of OSFED severity and then recursively partitioning the outcome model into severity groups. The SEM Tree-defined and clinical cutoff severity groups were compared on clinical characteristics. RESULTS: SEM Trees identified one split that occurred at value 5.12 on our shape/weight overvaluation items from the Eating Disorder Examination Questionnaire. The subgroup with higher overvaluation had significantly greater intensity of ED and depressive symptoms and longer lengths of stay. The subgroups created from the shape/weight overvaluation clinical-cut off value of 4 differed on the same clinical characteristics as the SEM Tree-derived groups, with the exception of laxative use frequency. Effect sizes were larger for the clinical cutoff as compared to the SEM Tree severity specification scheme. LIMITATIONS: These cross-sectional data were used from a predominately white and female residential treatment sample; this likely skewed the subgroups and may limit generalizability. CONCLUSIONS: Shape/weight overvaluation can meaningfully differentiate OSFED severity. The clinical cutoff slightly outperformed the empirically determined thresholds for shape/weight overvaluation.

RESUMO

Rhythmic gymnasts (RGs) are more likely to be dissatisfied with their body mass and shape compared to untrained controls (UCs). However, due to the lack of information, the aim of this study was to investigate the associations of body image perception (BIP) with body composition, daily energy consumption and different blood biochemical markers in adolescent RGs compared to UCs. Thirty-three highly trained RG girls and 20 UC girls aged 14-18 years participated in this cross-sectional study. Height, body mass, body composition, energy intake, resting energy expenditure, training volume and different blood biochemical markers were measured. The body attitude test (BAT) was used to evaluate the BIP of the participants. There were no differences in the total BAT scores between the groups. In RGs, the BAT score correlated positively with the serum resistin level (r = 0.35; p = 0.047). A stepwise multiple regression analysis showed that 40.8% of the variability in the BAT score was determined by resistin and BMI. The association of BIP with resistin values was observed only in RGs. In conclusion, our findings add to the increasing evidence that resistin may be a link between BIP and body composition, most likely through fat mass, in adolescent female RGs.
