Abstract

Abstract 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.Resumo Objetivo: Avaliar a associação entre razão Triglicerídeos e HDL-colesterol (TG/HDL-c) e fatores de risco cardiovascular em idosos. Método: Estudo epidemiológico transversal, com amostra probabilística de idosos (n=349), de ambos os sexos, atendidos na Estratégia Saúde da Família do município de Viçosa, MG. O risco cardiovascular foi calculado pela relação entre os níveis de TG sobre os níveis de HDL-c, sendo considerado em risco um valor maior que 3,5. Foram investigadas variáveis sociais e econômicas de estilo de vida, doenças crônicas não transmissíveis, níveis séricos de glicose, circunferência da cintura (CC) e índice de massa corporal. Para avaliar a associação entre a razão TG/HDL-c e as demais variáveis, foi utilizada regressão linear múltipla. As variáveis que se associaram à variável dependente com nível de significância menor que 0,20, na análise de regressão univariada, foram incluídas no modelo final (Stepwise-forward), adotando-se nível de significância p<0,05. Resultados: Os maiores valores da razão TG/HDL-c associaram-se com a presença da hipertensão arterial, ter sido ou ser fumante, apresentar elevados níveis séricos de glicose e possuir maior CC. Conclusão: Os achados refletem a importância de estudos sobre risco cardiovascular em idosos, devendo os profissionais da área da saúde ter familiaridade com os parâmetros que classificam os indivíduos com risco cardiovascular, sendo a razão TG/HDL-c um método confiável, com fácil aplicabilidade e boa correlação com efeitos adversos à saúde.
