Abstract

Background: The aim of this study was to investigate the relationship among apolipoprotein E (APOE) polymorphism, body mass index (BMI), and dyslipidemia and how these factors modify overall mortality in a cohort of hospitalized elderly patients. Methods: Plasma concentrations of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), BMI, and APOE genotype were evaluated in 1,012 hospitalized elderly patients, who were stratified into three groups according to their baseline BMI and APOE allele status. Multivariate logistic regression analysis was used to assess whether APOE genotype, BMI, and dyslipidemia are associated with mortality, adjusting for potential confounders. Interaction analysis was also performed. Results: Obese patients have significantly higher levels of TC and LDL-C compared to normal-weight and overweight subjects, for both sexes. APOE ε4 carriers have significantly higher levels of TC and LDL-C compared with ε2 and ε3 carrier both in males and females. Interaction analysis showed that women with TC
