Objective: To evaluate the association between triglycerides and HDL-cholesterol (TG/ HDL-c) ratio and cardiovascular risk factors among the elderly. Method: A cross-sectional epidemiological study with a random sample of elderly persons (n=349) of both genders, who received care under the Family Health Strategy in the municipality of Viçosa, in the state of Minas Gerais, was performed. Cardiovascular risk was calculated by the relationship between the TG and the HDL-c levels, with values greater than 3.5 considered a risk. Social and economic variables, lifestyle, noncommunicable chronic diseases, serum glucose levels, waist circumference (WC) and body mass index were evaluated. Multiple linear regression was used to evaluate the association between the TG/HDL-c ratio and other variables. Variables associated with the dependent variable with a level of significance lower than 0.20 in univariate regression analysis were included in the final model (stepwise-forward), applying a significance level of p<0.05. Results: The highest TG/HDL-c ratio values were associated with the presence of hypertension, having been or currently be a smoker, having elevated serum glucose and an increased waist circumference. Conclusion: The findings reflect the importance of studies on cardiovascular risk in the elderly, as health professionals should be familiar with the parameters that classify at risk individuals. The TG/HDL-c ratio is a reliable classification method that is easy to apply and correlates closely with adverse health effects.

Objective: To investigate the association between dietary patterns and the socioeconomic aspects of elderly patients registered with the Family Health Strategy in Viçosa, Minas Gerais. Method: A cross-sectional study with a probabilistic sample was employed. To identify dietary patterns, dietary intake was assessed through a Food Frequency Questionnaire (FFQ) adapted for an elderly population. From the FFQ dietary patterns were identified by factor analysis. After the identification of the dietary patterns, logistic regression was performed considering each different dietary pattern and the related socioeconomic variables. Results: The consumption of a Fat and sugar pattern was greater among women and lower in elderly persons who considered themselves as mixed race. The consumption of the Balanced pattern was also lower among mixed race, married individuals, with one to four years of schooling and from the CDE economic classes. The Fruit and fish pattern was less consumed by elderly persons with 1-4 years of schooling, while the opposite was observed among those with five years or more of study. But the consumption of a Leafy vegetables pattern was lower among those with five or more years of schooling. Conclusion: The evaluation of the consumption of dietary patterns and the establishment of a relationship with the socioeconomic aspects of the elderly helps to achieve a better understanding of risk and protective factors for health.

O presente estudo teve como objetivo verificar a acurácia de medidas antropométricas e do nível de atividade física (NAF) como preditores do risco de pressão arterial (PA) elevada, por sexo, em crianças. Participaram do estudo 187 crianças, média de idade de 9,90 ± 0,7 anos, de ambos os sexos, estudantes de nove escolas (públicas e privadas) do município de Viçosa-MG em 2009. As crianças foram submetidos a avaliação antropométrica, composição corporal e aferição da PA. Em seguida, preencheram registro de atividades físicas e utilizaram pedômetro por sete dias. Foram delineadas curvas Receiver Operating Characteristic (ROC) para testar a acurácia das medidas antropométricas e NAF em predizer o risco de PA elevada. IMC, perímetros de cintura mensurados em três pontos anatômicos, somatório de quatro dobras cutâneas e NAF foram acurados em predizer PA elevada para as meninas. Por outro lado, para os meninos apenas o número de passos/dia foi acurado na predição do PA elevada. NAF prediz PA elevada em crianças, independente do sexo, enquanto medidas antropométricas prediz PA elevada apenas para crianças do sexo feminino.

Resumo O objetivo deste estudo foi determinar e comparar a magnitude da associação entre indicadores antropométricos com fatores de risco cardiometabólico em idosos. Trata-se de estudo transversal com 402 idosos atendidos pela Estratégia Saúde da Família no município de Viçosa-MG. Os fatores de risco considerados foram o excesso de gordura corporal, hipertensão arterial, alteração da glicemia e dos lipídeos séricos. A associação entre o índice de conicidade (IC) e a relação cintura/estatura (RCE) com os fatores de risco cardiometabólico foi avaliada pela análise de regressão linear múltipla. A amostra foi composta por 60,4% de mulheres e 36,3% de idosos com excesso de peso. O índice de conicidade e a relação cintura/estatura estiveram elevados em 57,2% e 88,1% dos idosos, respectivamente. Os resultados demonstraram que o aumento da gordura corporal, da pressão arterial diastólica, dos triglicerídeos, da glicemia e a redução do HDL-colesterol estão relacionados a maiores valores dos índices antropométricos avaliados. No entanto, a relação cintura/estatura apresentou maior magnitude de associação com os fatores de risco cardiometabólico do que o índice de conicidade.
