There is a growing recognition that positive psychological functioning (which includes constructs such as optimism and hope) influences health. However, the understanding of these underlying mechanisms in relation to health is limited. Therefore, this review sought to identify what the scientific literature says about the influence of optimism and hope on chronic disease treatment. A search was conducted in the PsycINFO, Scopus, Pubmed, and Web of Science databases using the indexing terms optimism, hope, chronic diseases, randomized controlled trial, and treatment between 1998 and 2015. In the articles, we identified the most studied diseases in context, the assessment instruments used, the participant characteristics investigated, the results found, and the publication dates. From our analysis of the articles that met our inclusion criteria, it appears that the study of these constructs is recent and there is evidence that individuals with greater optimism and hope seek to engage in healthier behaviors, regardless of their clinical status, and that this contributes to chronic disease treatment. More research is needed so that targeted interventions can be carried out effectively in chronic disease treatment.

ResumoObjetivo: Avaliar a concordância entre diferentes classificações de Índice de Massa Corporal (IMC) e verificar modelos de fórmulas propostas para estimativa de peso e altura que podem ser aplicadas na população idosa do Sul do Brasil. Método: Estudo transversal que avaliou 131 idosos residentes de três instituições de longa permanência para idosos (ILPIs) no Sul do Brasil, por meio de uma avaliação antropométrica, utilizando peso, estatura, altura do joelho, dobra cutânea subescapular, circunferência da panturrilha, circunferência do braço, circunferência abdominal e hemienvergadura. Resultados: A idade média da amostra foi de 78,9 anos, sendo 41,2% homens e 58,8% mulheres. De acordo com a classificação da Organização Mundial da Saúde (OMS), apenas dois idosos (1,5%) apresentaram baixo-peso, 63 idosos (48,1%) foram classificados como eutróficos e 66 (50,4%) foram classificados com sobrepeso, obesidade grau I e II. Já os pontos de corte estipulados por Lipschitz determinaram que 21 idosos (16%) se encontram com baixo-peso, 69 (52,7%) eutróficos e 41 (31,3%) com sobrepeso. Ao comparar as medidas de peso e altura aferidas com as mesmas medidas estimadas, percebe-se que a única que não mostrou diferença significativa foi a fórmula de estimativa de altura de Rabito. Conclusão: Os pontos de corte utilizados apresentaram moderada concordância, sendo que Lipschitz salienta uma maior faixa de risco para desnutrição. Comparando as medidas de peso e altura aferidas com as medidas estimadas, foi observado que somente a fórmula de estimativa de altura de Rabito pode ser aplicada para esta população. AbstractObjective: Assessing the concordance between different classifications of body mass index (BMI) and verify if the formulas to estimate weight and height, that can be applied to the elderly population in Southern Brazil.

Background: Metabolic syndrome is associated with increased risk of cardiovascular events disease and type 2 diabetes. Treatment includes modifications on life style, diet and physical activity. Treatment adherence plays a crucial role in the successful treatment of this disease.

Coconut oil (CO) has generated discussions about its possible effects on health, especially for being an oil rich in saturated fat, which is known to contribute to the development of atherosclerosis and cardiovascular diseases. On the other hand, CO contains high levels of lauric acid that is directly absorbed by enterocytes and may prevent the fat deposition in blood vessels. In addition, flavonoids and polyphenols present in CO may be beneficial in reducing the oxidative stress involved in the etiology of various diseases, for instance, cardiovascular diseases and cancer. This article aimed to review the likely benefits of CO and its effects related to oxidative stress, hyperlipidemia and chronicle diseases in humans.

Together with an analysis of previous works, we suggest that green juice did not cause an improvement in metabolic function and there is a need for further research on this issue, mainly through different interventions and other samples.

Objective: To verify the knowledge about food and nutrition and its association with the nutritional status of obese patients with noncommunicable diseases (NCDs), and to identify the relationship between information sources and level of knowledge. Method: Cross-sectional study that included 263 outpatients of a cardiology referral hospital in Porto Alegre, Rio Grande do Sul, Brazil. The participants filled out a questionnaire on socioeconomic data and knowledge about food and nutrition and had their nutritional status evaluated by body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR). Results: BMI showed a significant inverse association with the percentage of correct answers (p=0.002), as well as WC (p=0.000) and WHR (p<0.001). This was also true for education (p<0.001) and female gender (p=0.005) compared to males. More than 60% of patients reported using television and 23% reported using newspaper as sources of nutritional information. Conclusion: Our study revealed a significant association between BMI and the level of knowledge about foods, showing that there is need for more information on obesity-related NCDs for greater understanding by patients.
