摘要：Background: Non-alcoholic hepatic steatosis is characterized
by the buildup of triglycerides in hepatocytes, surpassing
5 to 10% of the total weight of the organ. Excess abdominal
fat is related to excess fat in the neck region, which is responsible
for a greater systemic release of free fatty acids in
comparison to the visceral region. However, although the
measurement of neck circumference is used for the evaluation
of excess body fat and is an efficient manner for identifying
obese individuals.
Objective: Evaluate the usefulness of the use of neck circumference
as an anthropometric tool for the nutritional assessment
of individuals with Non-alcoholic hepatic steatosis.
Methods: A cross-sectional study was conducted at a university
hospital in the city of Brazil, between July-December
2016. 49 male and female patient were analyzed.
Sociodemographic, behavioral, clinical and nutritional data
were collected. The statistical analysis was performed with
the aid of the Statistical Package for Social Sciences.
Results: The group of patients with larger neck circumference
values had larger mean values for waist-to-height ratio
(p<0.01), body mass index (p<0.001), waist circumference
(p<0.001) and arm circumference (p<0.01). Neck circumference
was also correlated with waist circumference (p<0.001),
body mass index (p<0.001), waist-to-hip ratio (p=0.003) and
arm circumference (p<0.001).
Discussion: Based on the neck circumference, 51% of the
sample was classified as obese, which is in agreement with
findings described by Frizon and Boscain who evaluated 155
healthy individuals in the state of Rio Grande do Sul and
found that 55% had an increased NC (p< 0.001).
Conclusion: Neck circumference is a simple, reliable, lowcost
tool that can be easily used in clinical practice and is associated
with abdominal obesity, proving to be a good method
of anthropometric evaluation for patients with Non-alcoholic
hepatic steatosis.
