Media influence may lead adolescents to internalize patterns of physical beauty, resulting in dissatisfaction with their own bodies when they are unable to match up to these patterns. In the constant search for an ‘ideal body’, adolescents may begin to develop risk behaviors for the development of eating disorders (ED). The object of this study was to analyze the influence of the mass media on body dissatisfaction (BD) and on ED in adolescents, comparing genders. We also analyzed the influence of BD on the risk of developing unsuitable eating behaviors, with risk of ED, comparing genders. A cross-sectional study was carried out with 1011 adolescents: 527 girls and 484 boys. The BMI of each adolescent was determined, and the instruments EAT-26, Sociocultural Attitudes towards Appearance Questionnaire-3 (SATAQ-3), and body shape questionnaire (BSQ), were applied. For statistical analysis, we used Student’s t-test, the chi-square test, Pearson’s correlation test, the odds ratio, and hierarchical multiple linear regression. The influence of the mass media is associated with a greater probability of adolescents presenting BD. An increase in BD is associated with an increased risk of developing ED in adolescents of both genders but is greater in girls than in boys. Furthermore, the influence of the MM and BMI are predictors of BD in both genders; and BD is a predictor of ED risk in both girls and boys.
Background: The present study investigated the influence of body dissatisfaction (BD) on the self-esteem of Brazilian adolescents. Methods: A cross-sectional study was carried out with 1011 students at public and private schools in the city of Fortaleza, Brazil. The body shape questionnaire and the Rosenberg self-esteem scale were applied. Chi-square test, Student’s t-test, Pearson’s correlation, the odds ratio and binary logistic regression were used. Results: The rate of low self-esteem was 33.8% in the adolescents; 27.8% of the adolescents presented some degree of BD, with severe BD in 5.8%. A significant low negative correlation was found between self-esteem and BD in all the adolescents. In the Odds Ratio analysis, it was observed that the odds of having low self-esteem increased in adolescents with BD as compared to adolescents without BD, being 3.85 times higher in females (CI 95%, 2.12–6.99), 2.83 times higher in males (CI 95%, 1.22–6.58), 5.79 times higher in adolescents attending public schools (CI 95% 2.06–16.26), and 2.96 times higher in adolescents attending private schools (CI 95%, 1.79–4.88). Conclusions: Low self-esteem affected one-third of the adolescents, both male and female. BD and education in public schools are predictor variables of low self-esteem in adolescents.
A preocupação com a aparência física é algo indispensável ao ser humano e é cada vez mais preponderante em nossa sociedade que, através de diversos meios, evidencia corpos esteticamente perfeitos. No decorrer dos últimos anos, houve uma crescente preocupação com a imagem corporal (IC). Como a maioria da população não se encaixa nos padrões que a mídia impõe, podem surgir distorções da IC. A imagem corporal configura-se como a figura mental que temos do nosso corpo, juntamente de como sentimos, de como queremos que ele seja. Objetivo: o objetivo da pesquisa foi realizar uma revisão de literatura sobre imagem corporal, identificando suas causas e implicações nos adolescentes. Método: a pesquisa realizada caracteriza-se como uma revisão de literatura. A busca dos artigos ocorreu nos meses de setembro a novembro de 2015, nas bases de dados eletrônicas Scielo, Medline, Pubmed, Scopus e Lilacs. Resultados: foram encontrados 56 artigos, conforme os requisitos da pesquisa; foram utilizados 23 artigos para revisão. Considerações finais: a influência das relações sociais, na transformação da IC, exerce um papel fundamental na atual sociedade. O fator simbólico do corpo tornou-se fator fundamental de inserção social, especialmente entre os jovens. INTRODUÇÃOA Imagem Corporal (IC) é a figuração do corpo formada em nossa mente, ou seja, o modo pelo qual o corpo se apresenta para nós.1 Ainda assim a autoimagem conceitua-se na figura mental que temos das partes do nosso corpo, no formato e sua medida, juntamente com sentimentos de desejo de como queremos que elas sejam. 2A imagem corporal reúne os fatores físicos, emocionais e mentais em cada ser humano e a saúde mental só é conseguida quando a percepção do corpo chega
Atualmente as pessoas têm relacionado problemas de saúde às mudanças climáticas de forma direta ou indireta, ocasionando o aumento da prevalência de certas doenças. Nessa perspectiva foi realizada uma revisão de literatura de 14 artigos que abrangem este assunto. A maior parte dos estudos indicou associação entre fatores do clima e desfechos na saúde humana. O objetivo deste artigo é dar a conhecer estudos desenvolvidos que revelam a associação entre o clima e a saúde humana. Observamos que ainda existem poucas pesquisas que relacionam mudanças climáticas e saúde e é de suma importância que novos estudos sejam realizados para melhor compreendermos este assunto.
The object of the present study was to carry out a literature review to analyze the influence of physical activity and dietary behavior on body mass index in school-age children and adolescents. A search was carried out using the PubMed and LILACS databases, in which 1,412 articles were found. After application of inclusion and exclusion criteria, 17 studies were selected for qualitative analysis. Overweight and obesity were related with incorrect dietary habits (skipping breakfast, consumption of foods with high fat contents and high-sugar soft drinks), low levels of physical activity and long hours devoted to sedentary activities (playing video games or watching TV) were also related.
