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.

Background/Objectives: Anethole, a terpenoid with several pharmacologic effects, is the major constituent of the essential oil of Croton zehntneri (EOCz), Pax & K. Hoffm, Euphorbiaceae. Due to the mild renal toxicity associated with high doses of EOCz, its potential therapeutic effects on several diseases, and the fact that its chemical composition consists of 80% anethole, the renal effects of anethole in mice were investigated. Methods: Mice were randomly divided into eight groups, dosed daily as follows: Group 1—CTRL (control; vehicle only); Groups 2—A100, 3—A125_2x, and 4—A250 (dosed with 100, 125 twice daily, and 250 mg/kg, per os anethole); Group 5—_SUBAKI (i.p. albumin to induce hyperproteinemia and proteinuria; subclinical acute kidney injury); and Groups 6—_SUBAKI+A100, 7—_SUBAKI+A125_2x, and 8—_SUBAKI+A250 (per os anethole + i.p. albumin). Results: The A125_2x and A250 groups significantly increased urinary proteinuria and interstitial inflammation (p < 0.001, for these groups). _SUBAKI+A100, _SUBAKI+A125_2x, and _SUBAKI+A250 showed a neither protective nor additive effect in the proteinuria induced by anethole and by administered albumin. The anethole-induced proteinuria was spontaneously reversible in approximately 4 weeks. In vitro experiments showed that anethole (300 µg/mL) inhibits albumin uptake from the culture medium by tubular cells. Conclusions: Anethole at high doses bears renal acute toxicity that, although mild and spontaneously fully reversible, must be taken into consideration in a cost–benefit analysis.

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.

Objetivo: o presente estudo teve como objetivo analisar o perfil de estilo de vida de acadêmicos do curso de Licenciatura em Educação Física em uma Instituição particular de ensino superior. Metodos: foram avaliados 100 acadêmicos de ambos os sexos, através do questionário Pentáculo do Bem-Estar. Resultados e discussão: pôde ser constatada a presença de afirmações que declararam comportamentos com predominância de índices positivos em todos os itens, muito embora, também tenham sido encontrados alguns índices considerados regulares e para o resultado positivo do grupo, não prevaleceu em nenhum componente o índice negativo. Portanto, sugere-se que o perfil do estilo de vida dos acadêmicos investigados está, mesmo com poucas ressalvas, referente há alguns poucos índices regulares, em conformidade com o que preconiza a literatura, já que obtiveram a prevalência de índices positivos em todos os componentes. Considerações finais: diante do que foi tratado neste trabalho, sugere-se ao público alvo que adote meios para estarem sempre em busca do índice de estilo de vida positivo, assim como, a Instituição onde foi realizada a pesquisa, a realização de ações de conscientização e de incentivo para uma melhora do estilo de vida de seus acadêmicos.

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.
