Comparison of Female Body Image Between Models and Non-Models Women / Comparação da Imagem Corporal Feminina entre Modelos de Passarela e Mulheres Não-Modelo / Comparación de la Imagen Corporal Femenina entre Modelos de Pasarela y Mujeres No Modelos

Abstract Women have been dissatisfied with their own appearance. This study aimed to evaluate whether the media can influence changes in body image regarding weight concern, satisfaction and dysfunctional investment of one's own appearance in female runway models and non-models. This survey was composed of Brazilian women, models who were linked with an agency, and non-models. Data collection was carried out using Google Forms, sending links to invite eligible subjects. In total, 102 models and 247 non-models participated in the survey. Sample Characterization Questionnaire, weight and height reports for the Body Mass Index, Sociocultural Attitudes Toward Appearance Questionnaire-3 (SATAQ-3), Multidimensional Body-Self Relations Questionnaire - Appearance Scales (MBRSQ /AS) and Appearance Schemas Inventory - Revised (ASI-R) were used. The result showed that non-models are more susceptible to pressure from the media and that having body measurements considered ideal, like models, reduces social pressure on the body.

Resumo Mulheres têm se mostrado insatisfeitas com a própria aparência. O objetivo do estudo foi avaliar se a mídia pode influenciar alterações na imagem corporal em relação à preocupação com o peso, satisfação e investimento disfuncional da própria aparência no público de mulheres modelos de passarela e não-modelos. Pesquisa utilizou brasileiras, modelos que foram vinculadas a uma agência, e não-modelos. Coleta foi realizada pelo Google Forms com envio de links convidando as participantes. Participaram da pesquisa 102 modelos e 247 não-modelos. Instrumentos utilizados foram um Questionário de Caracterização da Amostra, relato de peso/altura para o Índice de Massa Corporal, Sociocultural Attitudes Toward Appearance Questionnaire-3 (SATAQ-3), Multidimensional Body-Self Relations Questionnaire - Appearance Scales (MBRSQ/AS) e Appearance Schemas Inventory - Revised (ASI-R). Resultado demonstrou que as não-modelos estão mais suscetíveis às pressões da mídia e que ter as medidas corporais consideradas ideais, como as modelos, diminui a pressão social sobre o corpo.

Validation of the Muscle Dysmorphic Disorder Inventory (MDDI) in Brazilian Women.

Despite high levels of body dissatisfaction and an increasing drive for muscularity among Brazilian women, most of the existing literature on muscle dysmorphia focuses on men and has mainly been conducted in Western and English-speaking regions. As a result, one of the most widely used assessment tools for symptoms of the disorder, the Muscle Dysmorphic Disorder Inventory (MDDI), has not yet been evaluated in Brazilian women-an at-risk population. In the present study, we perform a psychometric evaluation of the Brazilian Portuguese translation of the MDDI in a sample of 515 women. We evaluated the factor structure using a two-step, split-sample exploratory and confirmatory factor analytic approach, which supported the original three-factor structure of the measure. Additionally, we found good internal consistency, convergent validity, and test-retest reliability of the measure. Collectively, these results support the use of the measure in Brazilian women and provide a foundation to expand the literature in this population.

Association between creatine kinase activity, oxidative stress and selenoproteins mRNA expression changes after Brazil nut consumption of patients using statins.

BACKGROUND & AIMS: Although the mechanisms by which statins promote muscle disorders remain unclear, supplementation with dietary antioxidants may mitigate statins' side effects. This study aimed to investigate whether the consumption of Brazil nuts modulates serum creatine kinase (CK) activity in patients regularly using statins. METHODS: The study was performed in the Ribeirão Preto Medical School University Hospital. Thirty-two patients in regular use of statins were divided according to CK activity levels (G1: increased or G2: normal) and received one unit of Brazil nut daily for 3 months. Body composition, blood selenium (Se) concentrations, erythrocyte glutathione peroxidase (GPX) activity, oxidative stress parameters, and CK activity were evaluated before and after supplementation. RESULTS: In both groups, supplementation with one Brazil nut daily for 3 months contributed to achieve decreased levels of CK activity in serum, with positive changes in plasma and erythrocyte Se concentrations (p < 0.0001), and increased levels of GPX activity. Among the parameters related to curbing of oxidative stress, we observed reduced levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in both groups after supplementation. We also found a moderately negative association between CK and GPX activity (r = -41; p < 0.02). Expression of selenoproteins GPX1, SELENOP, and SELENON after Brazil nut supplementation was unchanged. CONCLUSION: Brazil nut consumption enhanced the control of CK activity by improving oxidative stress biomarkers in patients using statins but did not modulate mRNA expression of selenoproteins.

Translation and validation of a Brazilian Portuguese version of the Body Appreciation Scale-2 in Brazilian adults.

We examined the psychometric properties of a Brazilian Portuguese translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). A sample of 990 Brazilian adults (560 women, 430 men; Mage = 31.10, SD = 8.94) completed the BAS-2 and measures of life satisfaction, self-esteem, actual-ideal weight discrepancy (women only), breast size dissatisfaction (women only), drive for muscularity (men only), and disordered eating behaviours. Exploratory factor analyses indicated that BAS-2 scores reduced to a single dimension with all 10 items in women and men. Confirmatory factor analysis supported the fit of this one-dimensional factor structure following freeing of error covariances between two pairs of items. BAS-2 scores achieved full scalar invariance across sex, and men had significantly higher BAS-2 scores than women. Internal consistency coefficients were adequate and test-retest reliability was supported up to three weeks in a subsample of 221 participants (140 women, 81 men). Evidence of construct validity was demonstrated through positive associations with indices of psychological well-being and negative associations with indices of negative body image and disordered eating behaviours. Availability of a Brazilian Portuguese translation of the BAS-2 should help to promote greater understanding of positive body image in the Brazilian context.

Psychometric properties of the Breast Size Rating Scale (BSRS) in Brazilian university women.

The present study examined the psychometric properties of a Brazilian Portuguese translation of the Breast Size Rating Scale (BSRS). A total of 194 Brazilian university women completed the BSRS along with measures of body satisfaction, body appreciation, weight discrepancy, and attitudes toward societal appearance ideals. They also had their actual bra size and body mass indices (BMIs) objectively measured. Results indicated evidence of adequate convergent validity insofar as greater breast size dissatisfaction was significantly associated with greater weight discrepancy, higher BMI, lower body appreciation, lower body satisfaction, greater use of information from society about appearance ideals, greater perceived pressure from society about appearance ideals, and greater internalisation of general and athletic appearance ideals, respectively. In our sample, 20.6% of women reported no breast size dissatisfaction, 65.5% desired a larger breast size, and 13.9% desired a smaller breast size. Findings demonstrate that BSRS scores are psychometrically sound and that breast size dissatisfaction is common among Brazilian women.

Effects of cafeteria diet and high fat diet intake on anxiety, learning and memory in adult male rats.

OBJECTIVE: The effects of cafeteria and high fat diets were investigated on animal models of behavior. METHODS: Male Wistar rats were treated with Control (C), Cafeteria (CD) and High Fat (FD) diets and tested in the Elevated Plus-Maze (EPM) and Morris Water Maze (MWM) procedures. Body weight, length, abdominal circumference, retroperitoneal and epididymal adipose tissues were recorded. Physical parameters, weight of tissues, EPM, and MWM data were subjected to ANOVA followed by Newman-Keuls test (P < 0.05). RESULTS: There were no differences on weight and length parameters between CD and C rats up to 98 days of age. However, abdominal circumferences were higher in CD as compared to C at 35 and 70 days of age, respectively, the 5th and the 7th weeks. FD presented lower measures of weight and abdominal circumference; nevertheless there was an increase on those parameters at the end of the nutritional treatment. Even without an apparent weight gain of CD and FD these animals presented a greater accumulation of retroperitoneal and epididymal adipose tissues. In addition, CD and FD demonstrated behaviors that can suggest lower anxiety. CD showed a better learning performance and FD showed better recall of previous learned information in the memory retention test. DISCUSSION: According to those data it was concluded that hypercaloric diet ingestion was capable of triggering metabolic alterations and possibly lowering anxiety associated to learning or memory improvement on a spatial task.

Estudo de validação e fidedignidade de escalas de silhuetas brasileiras em adolescentes / Validation and reliability study of the figure rating scales applied to brazilian adolescents

Objetivou-se avaliar a validade de construto e a fidedignidade das escalas de silhuetas de Kakeshita (2008) em adolescentes brasileiros.

Body image dissatisfaction, nutritional status, and eating attitudes in adolescents / Insatisfação corporal, estado nutricional e atitudes alimentares em adolescentes

The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls) aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT- 26) and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

O estudo investigou a relação entre insatisfação com a imagem corporal, estado nutricional e atitudes alimentares em adolescentes de uma pequena cidade do interior do Estado de São Paulo. Um total de 278 adolescentes (106 meninos e 172 meninas) entre 15 e 18 anos tiveram respondidas medidas de insatisfação com a imagem corporal, por meio de uma Escala de Figuras de Silhuetas, e de atitudes alimentares, pelo Eating Attitudes Test (EAT-26), além de terem seu peso e altura aferidos. Meninas relataram maiores índices de insatisfação e atitudes alimentares inadequadas quando comparadas aos meninos e, em ambos os sexos, os comportamentos alimentares inadequados tendem a aumentar conforme aumenta a insatisfação com a imagem. Além disso, a insatisfação foi maior entre os adolescentes com sobrepeso e obesidade. Estes resultados demonstram que a insatisfação com a imagem corporal e os comportamentos alimentares inadequados afetam adolescentes até mesmo de pequenas cidades de países em desenvolvimento, demonstrando a necessidade de mais estudos epidemiológicos para o reconhecimento precoce de populações em risco de desenvolver transtornos alimentares.

Geographic location, sex and nutritional status play an important role in body image concerns among Brazilian adolescents.

This study compared body image concerns among adolescents from different geographic locations in Brazil, and the influence of sex and nutritional status. Seven hundred eighty-eight adolescents completed the Body Shape Questionnaire (BSQ) and had their weight and height measured. There were significant cross-regional differences in BSQ scores. Also, body image concerns were more prevalent among girls and among overweight adolescents. It is suggested that sex and nutritional status may play an important role in body image concerns, which is more common between adolescents from urban areas. Furthermore, our findings contribute to the literature by examining patterns of body image concerns within subgroups of adolescents who have received little research attention on these issues.
