          Abstract

          Abstract The Tripartite Influence Model posits that sociocultural influences mediated by internalization and social comparison are predictors of disordered eating and body change behaviours. This study aimed to test the Tripartite Influence Model among Brazilian male university students, which has not been tested yet. 707 undergraduate students of the five Brazilian regions, completed measures of sociocultural influences, internalization, social comparison, body and muscularity dissatisfaction, disordered eating and body change behaviours. Structural equation modelling analyses showed good model-fitting. Parental influence was related to internalization, while peer influence with social comparison. Media influences were related to both internalization and social comparison. Internalization and social comparison are mediating variables that are related to body dissatisfaction and muscularity dissatisfaction. Finally, muscularity dissatisfaction was associated with body change behaviours.

          Resumo O modelo de influência dos três fatores indica que as influências socioculturais, mediadas pela internalização e a comparação social, são preditoras de comportamentos de risco para transtornos alimentares e comportamentos de mudança corporal. O estudo objetivou testar o Modelo de Influência dos Três Fatores para jovens adultos brasileiros, uma vez que o mesmo ainda não foi testado neste contexto. 707 homens, jovens universitários das cinco regiões brasileiras, responderam a instrumentos de avaliação das influências socioculturais, internalização, comparação social, insatisfação com o corpo e com a muscularidade, comportamentos de risco para transtornos alimentares e comportamentos de mudança corporal. Análise por meio de Modelagem de Equações Estruturais demonstrou adequados índices de ajustamento do modelo. As influências dos pais foram associadas com a internalização, enquanto as influências dos pares com a comparação social. Influência da mídia demonstrou associação tanto com a internalização quanto com a comparação social. A internalização e a comparação social são variáveis mediadoras que se relacionam com a insatisfação corporal e insatisfação com a muscularidade. Por fim, a insatisfação com a muscularidade esteve associada com os comportamentos de mudança corporal.

          Risk and maintenance factors for eating pathology: a meta-analytic review.

          Eric Stice (2002)
          This meta-analytic review of prospective and experimental studies reveals that several accepted risk factors for eating pathology have not received empirical support (e.g., sexual abuse) or have received contradictory support (e.g.. dieting). There was consistent support for less-accepted risk factors(e.g., thin-ideal internalization) as well as emerging evidence for variables that potentiate and mitigate the effects of risk factors(e.g., social support) and factors that predict eating pathology maintenance(e.g., negative affect). In addition, certain multivariate etiologic and maintenance models received preliminary support. However, the predictive power of individual risk and maintenance factors was limited, suggesting it will be important to search for additional risk and maintenance factors, develop more comprehensive multivariate models, and address methodological limitations that attenuate effects.

              The attractive female body weight and female body dissatisfaction in 26 countries across 10 world regions: results of the international body project I.

              This study reports results from the first International Body Project (IBP-I), which surveyed 7,434 individuals in 10 major world regions about body weight ideals and body dissatisfaction. Participants completed the female Contour Drawing Figure Rating Scale (CDFRS) and self-reported their exposure to Western and local media. Results indicated there were significant cross-regional differences in the ideal female figure and body dissatisfaction, but effect sizes were small across high-socioeconomic-status (SES) sites. Within cultures, heavier bodies were preferred in low-SES sites compared to high-SES sites in Malaysia and South Africa (ds = 1.94-2.49) but not in Austria. Participant age, body mass index (BMI), and Western media exposure predicted body weight ideals. BMI and Western media exposure predicted body dissatisfaction among women. Our results show that body dissatisfaction and desire for thinness is commonplace in high-SES settings across world regions, highlighting the need for international attention to this problem.
