ABSTRACT

Objective:

To investigate the association between neck circumference and anthropometric, clinical, and biochemical parameters in chronic kidney failure patients on hemodialysis.

Methods:

This is a cross-sectional study with patients with chronic kidney disease undergoing hemodialysis in Western Bahia. For the data collection, anthropometric measures were taken and clinical and biochemical data were gathered from the patient records and employing a structured questionnaire. A multiple linear regression was applied to evaluate the relationship between neck circumference and the anthropometric, clinical, and biochemical parameters.

Results:

A total of 119 patients were evaluated, of which 63.03% were men and 57.98% were aged between 35 and 59 years old. The mean neck circumference of the patients was 36.2±3.8 cm. A negative association was found between neck circumference and the female sex (p<0.001), while waist circumference (p<0.001), the body adiposity index (p=0.002), and pre-dialysis serum urea concentration (p=0.006) were positively associated with neck circumference.

Conclusion:

Neck circumference is inversely associated with the female sex and positively associated with a high waist circumference, body adiposity index, and serum urea concentration in patients with chronic kidney disease on hemodialysis.
