RESUMO

OBJECTIVE: The Muscularity-Oriented Eating Test (MOET) is a 15-item unidimensional scale, designed to assess eating practices that occur in the pursuit of a muscular body. The aim of the present study was to describe the translation and cultural adaptation of the MOET to Brazilian Portuguese, to explore its factor structure and measurement invariance, and to evaluate its internal consistency, three-week test-retest reliability, and convergent validity in a community sample of Brazilian men and women. METHOD: After the back-translation procedure, the Brazilian MOET was administered online to a sample of 1246 adults (634 men and 612 women), along with measures of drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating behaviors, and exercise dependence. RESULTS: Findings from an exploratory factor analysis and a confirmatory factor analysis revealed a one-factor structure and adequate internal consistency for men (ω = 0.86; α = 0.86) and women (ω = .84; α = .83). Measurement invariance across gender was supported. In addition, the scale demonstrated good three week test-retest reliability for both men (ICC = .96; p < .001) and women (ICC = .92; p < .001), and the subscales revealed moderate to large associations with drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating, and exercise dependence. CONCLUSION: This study supports the validity and reliability of the MOET in a community sample of Brazilian men and women and represents an advance in measures of muscularity-oriented disordered eating in Brazilian adults, allowing for future cross-cultural studies in this field. PUBLIC SIGNIFICANCE: The Muscularity-Oriented Eating Test (MOET) is a measure of muscularity-oriented disordered eating, which assess strict adherence to diet rules, including the food's macronutrient content, regulation of protein intake, and eating less or more to influence muscle gain. This study evaluated the validity and reliability of the MOET in a community sample of Brazilian men and women. Our findings represent an advance in measures of muscularity-oriented disordered eating in Brazilian adults.

RESUMO

OBJECTIVE: The present study investigated the psychometric properties of the Brazilian adaptation of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales, a widely used instrument in body image research. METHODS: We translated the MBSRQ-AS and determined its psychometric properties among 2 community samples, totaling 387 men and 381 women, and 1 college sample of 104 men and 133 women, aged from 16 to 67 years old (totaling 1005 participants). Near half of the sample (n = 606) was recruited online (SurveyMonkey Database) and the other half was personally recruited from universities, technical schools and libraries. RESULTS: The translated version was similar to the original, and the items were easily understood. After the exclusion of the negatively worded questions, the Brazilian version had the same factor structure as the original MBSRQ-AS. Internal consistency ranged from .73 to .90 and test-retest reliability indices ranged from .76 to .92. The measure captured sex and weight status differences. Women reported significantly higher levels of investment in appearance, lower levels of satisfaction with specific parts of the body, higher concerns with being overweight, and classified themselves as heavier than men. Overweight and obese men and women reported lower satisfaction with specific parts of their bodies, higher concerns with being overweight, and classified themselves as heavier than their normal weight counterparts. Convergent validity was demonstrated by the significant correlations between the MBSRQ-AS subscales and investment in appearance, internalization of beauty ideals, disordered eating and self-esteem. CONCLUSIONS: In summary, the Brazilian MBSRQ-AS appears to be a good option for researchers in the country. Furthermore, the study provides substantial parameters for comparison with other adaptations of the instrument around the world. LEVEL OF EVIDENCE: Level V, descriptive study.

RESUMO

The ORTO-15 is a commonly used screening instrument for symptoms of Orthorexia Nervosa (ON), an obsessive overconcern with healthy eating. However, its limitations have been evidenced in several published factorial models. We analyzed the psychometric properties of seven different ORTO-15 factorial models using data from Brazilian adult participants (n = 1455; 71.4% women; M age = 29.5, SD = 8.9 years) from the country's five macro-regions who answered online questions for sample characterization and completed the Portuguese version of the ORTO-15 containing 15 items. We tested the fit of each model separately, analyzing data for men and women with separate confirmatory factor analysis, and using the Weighted Least Squares Mean and Variance Adjusted estimation method and goodness-of-fit indices. We also calculated the average variance extracted and the alpha ordinal and omega coefficients to analyze the convergent validity and reliability of the factors. None of the models tested presented adequate properties of validity and reliability. Although we found some acceptable reliability coefficients, they do not guarantee the validity of the data. Future investigators should be cautious when choosing the ORTO-15 for ON screening.

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

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.

RESUMO

Brazilian women are known to present high levels of physical appearance concerns, and data suggest they often compare themselves with others. Nevertheless, there is no validated instrument to systematically assess appearance comparisons in the Brazilian population. Thus, this study aimed to translate the Physical Appearance Comparison Scale-Revised (PACS-R) into Brazilian Portuguese and evaluate its factor structure, internal consistency, and convergent validity in Brazilian college women. The translated version into Brazilian Portuguese of the PACS-R was completed by 832 Brazilian college women and its factor structure was examined through exploratory and confirmatory factor analyses, internal consistency through McDonald's omega, and convergent validity through its associations with measures of eating disorder symptoms, internalization of appearance ideals, appearance-related sociocultural pressures, body satisfaction, and self-esteem. The results suggested an 11-item single-factor scale. The Brazilian Portuguese PACS-R showed adequate internal consistency and was significantly associated with all measures of convergent validity in the expected direction, indicating its adequate convergent validity. The Brazilian Portuguese PACS-R might be useful in the investigation of the appearance comparison among women in Brazil, as also in the study of body image and eating disorders.

RESUMO

The scope of this study was to estimate the prevalence of dissatisfaction with body image and verify the association between dissatisfaction with thinness or with overweight and health-related physical fitness components among adolescents. Participants included 1058 adolescents (570 girls and 488 boys), with mean age of 16.3 (±1.0) years. The investigated variables were dissatisfaction with body image (Figure Rating Scale), and health-related physical fitness: body fat (skin folds), muscle strength (handgrip strength) and cardiorespiratory fitness (mCAFT test). The association of body image and the health-related physical fitness variables was tested by Multinomial Regression analysis. The prevalence of body dissatisfaction was 75.2% (girls = 79.5%; boys = 70.3%). Girls and boys with high body fat were less likely to be dissatisfied with thinness and more likely to be dissatisfied with overweight. Those who needed to improve muscle strength and cardiorespiratory fitness were more likely to be dissatisfied with thinness and with overweight, respectively. In conclusion, physical fitness was associated with body image, with the adolescents with less healthy conditions of the components being more dissatisfied.


O objetivo deste estudo foi estimar a prevalência de insatisfação com a imagem corporal e verificar a associação entre a insatisfação pela magreza e pelo excesso de peso e componentes da aptidão física relacionada à saúde em adolescentes. Participaram 1.058 adolescentes (570 moças e 488 rapazes), com média de idade de 16,3(± 1,0) anos. As variáveis investigadas foram a insatisfação com a imagem corporal (escala de silhuetas), e as relativas à aptidão física relacionada à saúde: adiposidade corporal (dobras cutâneas), força muscular (preensão manual) e aptidão cardiorrespiratória (teste mCAFT). A associação entre a imagem corporal e as variáveis de aptidão física foi testada por meio da Regressão Multinomial. A prevalência de insatisfação corporal foi de 75,2% (moças = 79,5%; rapazes = 70,3%). Moças e rapazes com adiposidade corporal elevada tiveram menor chance de insatisfação pela magreza e maior chance de insatisfação pelo excesso de peso. Os que necessitavam melhorar a força muscular e a aptidão cardiorrespiratória tiveram maior chance de insatisfação pela magreza e pelo excesso de peso, respectivamente. Conclui-se que a aptidão física relacionada à saúde esteve associada à imagem corporal, sendo que os adolescentes com níveis menos saudáveis dos diferentes componentes foram os mais insatisfeitos.

RESUMO

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.

RESUMO

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.

RESUMO

Introdução: Dificuldades de acesso aos alimentos e o distanciamento social desencadearam mais ansiedade, estresse e consumo de alimentos de baixo custo e ultraprocessados. Objetivo: Investigar as mudanças no comportamento alimentar e a relação deste com os aspectos socioeconômicos. Método: Estudo realizado virtualmente entre maio e junho de 2020 com 949 adultos, com questionários de dados socioeconômicos, mudanças no comportamento alimentar, frequência do consumo alimentar e o TFEQ-21. A análise foi realizada de forma descritiva e o TFEQ-21 de acordo com os escores de cada fator. A relação entre as variáveis foi analisada pelo teste de correlação de Pearson. Resultados: 63% consideraram cozinhar mais alimentos, 41% e 38% referiram maior possibilidade comer com companhia e com tranquilidade, respectivamente. Além disso, 38,6% reduziram compra de fast-food, mas 43,2% aumentaram o consumo alimentar e 41,8% o consumo de doces. Em mulheres, quanto maior o IMC, maior alimentação emocional e restrição cognitiva (p<0,001). Nestas, o comer emocional era maior se não possuíam filhos nem ensino superior (p<0,001), e a restrição era maior com a atividade física, não possuir relacionamento estável, ter filhos (p<0,001), emprego e ensino superior (p<0,05). Nos homens, o comer emocional se relacionou ao maior IMC (p<0,05) e ambas variáveis estavam relacionados à atividade física (p<0,001). Conclusão: Mudanças como cozinhar mais, reduzir fast-food, comer com tranquilidade e com companhia foram observadas comparados a antes da pandemia. Nota-se que nas mulheres há maior relação da restrição e do comer emocional com diversos aspectos do contexto social e econômico (AU).


Introduction: Difficulties in accessing food and social distancing triggered more anxiety, stress and consumption of low-cost and ultra-processed foods. Objective: To investigate changes in eating behavior and its relationship with socioeconomic aspects. Method: Study conducted virtually between May and June 2020 with 949 adults, with questionnaires on socioeconomic data, changes in eating behavior, frequency of food consumption and the TFEQ-21. The analysis was performed descriptively and the TFEQ-21 according to the scores of each factor. The relationship between the variableswas analyzed using Pearson's correlation test. Results: 63% considered cooking more food, 41% and 38% said they were more likely to eat with company and in peace, respectively. 38.6% reduced fast-food purchases, but 43.2% increased food consumption and 41.8% consumption of sweets. In women, the higher the BMI, the greater the emotional eating and cognitive restriction (p<0.001). In these, emotional eating was greater if they did not have children or higher education (p<0.001), and the restriction was greater with physical activity, not having a stable relationship, having children (p<0.001), employment and higher education (p<0.05). In men, emotional eating was related to higher BMI (p<0.05) and both variables were related to physical activity (p<0.001). Conclusion: Changes such as cooking more, reducing fast food, eating calmly and with company were observed compared to before the pandemic. It is noted that in women there is a greater relationship between restriction and emotional eating with various aspects of the social and economic context (AU).

RESUMO

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.

RESUMO

ABSTRACT Objective: Evaluate differences in disordered eating symptoms between men and women who practice CrossFit and to evaluate its predictors in this population. Methods: A cross-sectional study (April to June 2019) was carried out with 194 adults (103 women and 91 men) enrolled in private CrossFit boxes in Brazil, with a mean age of 30.19 years (SD = 5.34). Participants answered a sociodemographic questionnaire, the Eating Attitudes Test-26 (disordered eating), the Sociocultural Attitudes Towards Appearance Questionnaire-3 (body-ideal internalization), and the Drive for Muscularity Scale (drive for muscularity). A series of Student's t-tests was applied to test differences in disordered eating symptoms between men and women. Multiple linear regressions were conducted to evaluate predictors of disordered eating for both sexes. Results: Women showed greater disordered eating symptoms, dietary restrictions and excessive concern about thinness than men. Moreover, younger women with a higher BMI are more likely to have disordered eating symptoms. Higher drive for muscularity and greater general body-ideal internalization were also associated with disordered eating among women. In men, muscularity-oriented behavior was the only predictor of disordered eating. Conclusion: These findings are relevant, as they point out that women who practice CrossFit seem to be a high risk group for the development of eating disorders. In addition, muscularity-oriented behaviors in men and the drive for muscularity, internalization of the ideal body, BMI and age in women are predictors of disordered eating in CrossFit practitioners.


RESUMO Objetivo: Avaliar possíveis diferenças nos sintomas de transtornos alimentares entre homens e mulheres que praticam CrossFit e seus preditores nessa população. Métodos: Realizou-se um estudo transversal (abril a junho de 2019) com 194 adultos (103 mulheres e 91 homens) matriculados em academias de CrossFit particulares de Ribeirão Preto, com média de idade de 30,19 anos (DP = 5,34). Foram respondidos um questionário sociodemográfico, o Eating Attitudes Test-26 (sintomas de transtornos alimentares), o Sociocultural Attitudes Towards Appearance Questionnaire-3 (internalização do ideal de corpo) e a Drive for Muscularity Scale (busca pela muscularidade). Resultados: As mulheres apresentaram mais sintomas de transtorno alimentar, maiores restrições alimentares e preocupação excessiva com a magreza. Além disso, mulheres mais jovens com IMC mais alto têm maior probabilidade de apresentar sintomas de distúrbios alimentares. Maior busca pela muscularidade e maior internalização geral dos padrões de corpo socialmente estabelecidos também foram associados com alimentação desordenada entre as mulheres. Nos homens, o comportamento orientado para a muscularidade foi o único preditor dos transtornos alimentares. Conclusão: Esses achados são relevantes, pois apontam que as mulheres praticantes de CrossFit parecem apresentar maior risco para o desenvolvimento de transtornos alimentares. Além disso, comportamentos orientados para a musculatura em homens e a busca pela muscularidade, internalização do ideal de corpo, IMC e idade nas mulheres são preditores de transtornos alimentares em praticantes de CrossFit.

RESUMO

The aim of this study was to investigate gender differences in the accuracy of body size estimation and body dissatisfaction among Brazilian undergraduates and their relationships with perceptions of the ideal body silhouettes that would be selected by same-gender and opposite-gender peers. A total of 159 undergraduates (79 males) from a public University in Ribeirao Preto, Sao Paulo, Brazil, participated in the study. They completed a Figure Rating Scale and indicated the figure that best describes the size of their own body (actual), their desired body, the body they judged would be ideal to same-gender peers, and the body they judged would be ideal to opposite-gender peers. The results showed that women were less precise in estimating their actual size and more dissatisfied. The mean Body Mass Index (BMI) that was selected as "current" by women was significantly higher than their desired and ideal BMIs, whereas the mean BMIs that were selected by men were practically the same. Men and women selected ideal silhouettes for their own gender that were the same as those that were selected as ideal by the opposite gender. The mean BMIs that were actually chosen by men and women as desired and ideal were closer to the upper end of normal weight and lower end of overweight, respectively. Such results contradict what has been assumed to be a normative characteristic of men and women in several countries, raising some doubts regarding the role of beliefs about judgments of the opposite gender in the development of body image disturbances.

RESUMO

ABSTRACT Purpose: to determine whether undernutrition in the first years of life affects the phonological awareness skills, the phonological working memory and the school performance of children. Methods: the participants were children with a history of moderate/severe undernutrition during their first years of life (G1) who achieved nutritional recovery (n = 15). The performance of G1 in different cognitive tasks (phonological awareness at the syllable and phoneme level, phonological working memory - repetition of digits and pseudowords, and reading, writing and arithmetic activities) was compared to that of children with school difficulties (G2) (n = 15) and without school difficulties (G3) (n = 15), all eutrophic ones. Results: the performance of G1 was worse than that of the other two groups in all tasks evaluated (mean score of G1, G2 and G3 and p-values: phonological awareness: 31, 41, 57 - 0.01; repetition of direct order digits: 18, 23, 28 - 0.001; writing: 4, 10, 22 - 0.001; reading: 26, 45, 65-0.001; arithmetic: 4, 7, 11- 0.001). Conclusion: the results demonstrate that undernutrition affected the cognitive development, causing changes in important cognitive skills for the development of written language.


RESUMO Objetivo: analisar se a subnutrição sofrida por crianças nos primeiros anos de vida afetou suas habilidades de consciência fonológica, memória de trabalho fonológica e desempenho escolar. Métodos: participaram crianças com histórico de subnutrição moderada/grave nos primeiros anos de vida (G1) que foram recuperadas nutricionalmente (n = 15). O desempenho desse grupo (G1) em diversas tarefas cognitivas (consciência fonológica no nível da sílaba e do fonema, memória de trabalho fonológica - repetição de dígitos e de pseudopalavras, atividades de leitura, escrita e cálculo aritmético) foi comparado, ao desempenho de crianças com dificuldades escolares (G2) (n = 15) e sem dificuldades escolares (G3) (n = 15), todas eutróficas desde o nascimento. Resultados: observou-se pior desempenho (diferença estatística significante) de G1 em relação aos outros dois grupos em todas as tarefas avaliadas (pontuação média do G1, G2 e G3 e p-valores: Consciência fonológica: 31, 41, 57 - 0.01; Repetição de dígitos ordem direta: 18, 23, 28 - 0.001; Escrita: 4,10,22 - 0.001; Leitura: 26, 45, 65 - 0.001; Aritmética: 4, 7, 11 - 0.001). Conclusão: os resultados evidenciaram que a subnutrição em idade precoce afetou o desenvolvimento cognitivo (habilidades de consciência fonológica e memória de trabalho fonológica) e, por consequência prejudicou o desempenho acadêmico.

RESUMO

Resumo O objetivo deste estudo foi estimar a prevalência de insatisfação com a imagem corporal e verificar a associação entre a insatisfação pela magreza e pelo excesso de peso e componentes da aptidão física relacionada à saúde em adolescentes. Participaram 1.058 adolescentes (570 moças e 488 rapazes), com média de idade de 16,3(± 1,0) anos. As variáveis investigadas foram a insatisfação com a imagem corporal (escala de silhuetas), e as relativas à aptidão física relacionada à saúde: adiposidade corporal (dobras cutâneas), força muscular (preensão manual) e aptidão cardiorrespiratória (teste mCAFT). A associação entre a imagem corporal e as variáveis de aptidão física foi testada por meio da Regressão Multinomial. A prevalência de insatisfação corporal foi de 75,2% (moças = 79,5%; rapazes = 70,3%). Moças e rapazes com adiposidade corporal elevada tiveram menor chance de insatisfação pela magreza e maior chance de insatisfação pelo excesso de peso. Os que necessitavam melhorar a força muscular e a aptidão cardiorrespiratória tiveram maior chance de insatisfação pela magreza e pelo excesso de peso, respectivamente. Conclui-se que a aptidão física relacionada à saúde esteve associada à imagem corporal, sendo que os adolescentes com níveis menos saudáveis dos diferentes componentes foram os mais insatisfeitos.


Abstract The scope of this study was to estimate the prevalence of dissatisfaction with body image and verify the association between dissatisfaction with thinness or with overweight and health-related physical fitness components among adolescents. Participants included 1058 adolescents (570 girls and 488 boys), with mean age of 16.3 (±1.0) years. The investigated variables were dissatisfaction with body image (Figure Rating Scale), and health-related physical fitness: body fat (skin folds), muscle strength (handgrip strength) and cardiorespiratory fitness (mCAFT test). The association of body image and the health-related physical fitness variables was tested by Multinomial Regression analysis. The prevalence of body dissatisfaction was 75.2% (girls = 79.5%; boys = 70.3%). Girls and boys with high body fat were less likely to be dissatisfied with thinness and more likely to be dissatisfied with overweight. Those who needed to improve muscle strength and cardiorespiratory fitness were more likely to be dissatisfied with thinness and with overweight, respectively. In conclusion, physical fitness was associated with body image, with the adolescents with less healthy conditions of the components being more dissatisfied.

RESUMO

CONTEXT AND OBJECTIVE: Malnutrition is one of the causes of changes in cell metabolism. The inner ear has few energy reserves and high metabolism. The aim of this study was to analyze whether malnutrition at an early age is related to impairment of auditory processing abilities and hearing abnormalities. DESIGN AND SETTING: Retrospective cohort study conducted in a tertiary public hospital. METHODS: 45 children participated, divided as follows: G1, children diagnosed with malnutrition in their first two years of life; G2, children without history of malnutrition but with learning difficulties; G3, children without history of malnutrition and without learning difficulties. Tympanometry, pure-tone audiometry and the Staggered Spondaic Word (SSW) test (auditory processing) were performed. Statistical inferences were made using the Kruskal-Wallis test (α = 5%) and the test of equality of proportions between two samples (α = 1.7%). RESULTS: None of the 45 children participating in this study presented hearing deficiencies. However, at six of the eight frequencies analyzed, the children in G1 presented hearing thresholds lower than those of the other groups. In the auditory processing evaluation test, it was observed that 100% of the children in G1 presented abnormal auditory processing and that G1 and G2 had similar proportions of abnormalities (P-values: G1/G2 = 0.1; G1/G3 > 0.001; G2/G3 = 0.008). CONCLUSIONS: Malnutrition at an early age caused lowering of the hearing levels, although this impairment could not be considered to be a hearing deficiency. Every child in this group presented abnormalities in auditory processing abilities.

RESUMO

OBJECTIVE: To analyze Brazilian literature on body image and the theoretical and methodological advances that have been made. METHODS: A detailed review was undertaken of the Brazilian literature on body image, selecting published articles, dissertations and theses from the SciELO, SCOPUS, LILACS and PubMed databases and the CAPES thesis database. Google Scholar was also used. There was no start date for the search, which used the following search terms: "body image" AND "Brazil" AND "scale(s)"; "body image" AND "Brazil" AND "questionnaire(s)"; "body image" AND "Brazil" AND "instrument(s)"; "body image" limited to Brazil and "body image". RESULTS: The majority of measures available were intended to be used in college students, with half of them evaluating satisfaction/dissatisfaction with the body. Females and adolescents of both sexes were the most studied population. There has been a significant increase in the number of available instruments. Nevertheless, numerous published studies have used non-validated instruments, with much confusion in the use of the appropriate terms (e.g., perception, dissatisfaction, distortion). CONCLUSIONS: Much more is needed to understand body image within the Brazilian population, especially in terms of evaluating different age groups and diversifying the components/dimensions assessed. However, interest in this theme is increasing, and important steps have been taken in a short space of time.

RESUMO

The scope of this article is to evaluate the body image of adolescents from rural cities and its relationship with nutritional status, sex and the adolescent phase. Adolescents of both sexes participated in the cross-sectional study. Body image was evaluated through the Body Shape Questionnaire (BSQ) and the Figure Rating Scale (FRS) for adolescents. Weight and height were measured for the evaluation of body mass index (BMI). Stages of adolescence were classified by age. Descriptive and inferential statistical analyses were conducted. Four hundred and forty-five adolescents (190 boys and 255 girls), with a mean age of 16.44 comprised the sample. Higher risk of body dissatisfaction was found among overweight and obese participants (BSQ: OR = 3.359 p < 0.001; ESA: OR = 1.572 p = 0.387) and the female sex (BSQ: OR = 3.694 p < 0.001; ESA: OR = 0.922, p = 0.840). Participants from the intermediary and final stages of adolescence revealed a lesser risk of dissatisfaction compared to those from the initial phase. Body dissatisfaction was related to overweight and obesity, to the female sex and to the initial period of adolescence. Intervention research is required to control the factors that influence excessive adolescent body dissatisfaction.

RESUMO

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.
