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. Method: Cross-sectional analysis was applied to 131 elders from three long-stay institutions in Southern Brazil. They were Palavras-chave: Idoso. Índice de Massa Corporal.

Malnutrition was frequent and hand-grip strength seemed to be the most sensitive method for its diagnosis. Calories and protein intakes were inadequate. Considering that the predicted resting energy expenditure was higher than the measured one and the need to offer higher caloric intake, the use of the predicting equation may replace indirect calorimetry.

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.

Background Carriers of hepatitis C virus have lower levels of total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein- cholesterol and triglycerides compared to uninfected patients. With the progression of liver disease, the values ​​for cholesterol and its fractions reduce linearly, with reduction ratio of lipid profile and markers Child-Pugh and MELD. Aim To determine the relationship between decrease dlipid profile with clinical outcome presented (liver transplantation or death pre-transplant). Methods Was conducted a cross sectional analytical study of a follow-up study performed by reviewing medical records. Cirrhotic patients treated at theClinic of Gastroenterology from a large tertiary hospital with cirrhosis of viral etiology and/or alcohol were studied. The clinical characteristics (gender, age and etiology of cirrhosis) and lipid profile data from150 patients were collected in the year 2010.To analyze the occurrence of clinical outcomes (liver transplantation or death pre-transplant) patients were evaluated after four years. Results The prevalent cause was hepatitis C virus (53,3%), followed by alcohol (32%) and hepatitis C and alcohol (14,6%). Males represented 62% of the sample and the average age was 63.1±9.11 years. The prevalent lipid changes were hypocholesterolemia associated with hypotriglyceridemia (36,6%) and isolated hypocholesterolemia (34,6%). Analyzing groups of patients that showed abnormalities related to lipid profile, was identified a significant association between isolated hypocholesterolemia and clinical outcome-liver transplant(p <0.025) and 18% probability of performing liver transplantation in this group of patients. There was no association between decreased lipid profile and death. Conclusion Isolated hypocholesterolemia contributes to assess the progression of liver disease, because of the association between lowering cholesterol and its fractions and the clinical outcome - liver transplant

Malnutrition is frequently in hepatitis C virus patients. They have high prevalence of inadequate energy, protein and micronutrients intake, even in the absence of cirrhosis.
