The Correlation of Neck Circumference with the Metabolic Age of Obesity

Abstract

Fat accumulation in obesity stimulates an increase in the production of pro-inflammatory mediators in the

body chronically, causing the cell’s metabolic age to be older than the chronological age. This situation

can cause a decrease in metabolic rate; therefore, the body is at risk of cardiometabolic disease. Neck

circumference (NC) is known as an anthropometry which is closely related to obesity, visceral fat, and

metabolic syndrome. The purpose of this study was to determine the correlation of NC with increasing

cell’s metabolic age so that it can serve as a simple anthropometry in predicting cell’s metabolic age. The

study was conducted with a cross-sectional design. The sample of the study was adult male and female with

age 30-59 years and following the inclusion and exclusion criteria. The anthropometric examination was

carried out in the form of body mass index, neck circumference, and cell’s metabolic age using Bioelectrical

Impedance Analyzer. Total samples obtained were 94 obese subjects with a mean BMI, NC and metabolic

age was 26.9 kg /m2, NC 34.1 cm, and 50 years. There was a significant positive correlation between NC and

cell’s metabolic age (p = 0.001; r = 0.42). In conclusion, NC is useful as simple and practical anthropometry

used to predict the increase in metabolic age of cells.
