Use of neck circumference as a predictor of cardiovascular risk in chronic kidney patients undergoing hemodialysis candidates for transplantation.

INTRODUCTION Patients undergoing hemodialysis have a great cardiovascular risk. Neck circumference is a simple and low-cost measure that can estimate this risk precociously. OBJECTIVE To evaluate whether the cardiovascular risk obtained by Neck Circumference (NC) is associated with the main cardiometabolic risk factors in patients on hemodialysis treatment on waiting list for transplantation. METHODS cross-sectional study including 96 patients in a single transplantation center. Sociodemographic, clinical-laboratory and anthropometric data were collected. NC was considered as a dependent variable and the independent variables were body mass index (BMI), biochemical tests of fasting glycemia and lipid profile, triglyceride ratio and high density lipoprotein cholesterol (TGL / HDL-C) and triglyceride Index and glycemia (TyG). For the comparison of averages, we used the Mann Whitney and Students t Tests, as well as the one-way ANOVA and Kruskal Wallis tests. Bivariate and multivariate logistic regression was performed for the association between NC and cardiometabolic risk factors. A significance level of 5% was assumed. RESULTS There were higher BMI averages, blood glucose, triglycerides (TGL), TGL/HDL-C ratio and TyG index in the tertile 3 of the NC, whereas the HDL-c decreased as the tertile increased. There was a statistically significant risk of cardiovascular disease, according to NC, with overweight, high levels of TGL, TGL/HDL-c, TyG index, and low HDL-c. CONCLUSION NC has been shown to be associated with cardiometabolic risk factors in kidney patients undergoing hemodialysis on transplant waiting lists.
