Neck circumference as a measure of neck fat and abdominal visceral fat in Chinese adults

摘要

Background Visceral adipose tissue (VAT) is a unique pathogenic fatty deposit, in that it is closely correlated with risk of cardiovascular diseases. The present study is to investigate the usefulness of neck circumference (NC) to indicate VAT. Methods Participants aged 35 to 75?years who had taken abdomen and neck computer tomography (CT) examination were included in this study. Neck adipose tissue, abdominal VAT and subcutaneous adipose tissue (SAT) areas, as well as sagittal abdominal diameter (SAD) were measured by CT. Body anthropometrics and metabolic parameters including blood glucose, lipid profiles and blood pressure were also measured. Results A lower abdomen CT examination was carried out on a total of 177 patients (87 male and 90 female) with a mean age of 59?years. Of the 177 participants, 15 men and 15 women also took a neck CT examination. With a comparable age and BMI, neck adipose area was correlated with abdominal VAT area significantly in men (r?=?0.57, p?=?0.028) and women (r?=?0.53, p?=?0.041). NC is positively correlated with VAT both in men (r?=?0.49, p? Conclusion Significant correlation between NC and VAT was present in Chinese men and women, which may be accounted by the fact that neck fat area is significantly correlated with abdominal VAT. Meanwhile, SAD is the best predictor for visceral fat in the Chinese population.
