Abstract

Neck circumference (NC) reflects the fat deposition in upper body and has potential to be used as a predictor of Non-Alcoholic Fatty Liver Disease (NAFLD). Our objectives were to examine the association of NC with NAFLD prevalence, and to determine the optimal cut-off of NC in identifying the presence of NAFLD among the employees of an academic institution in Bangkok, Thailand. In this cross-sectional study, 635 employees of an academic institution underwent anthropometric measurement and transient elastography following an overnight fast. NAFLD was defined as a CAP value >238 dB.m-1. The NAFLD prevalence in men and women were 66.17% and 46.22%, respectively. The mean NCs for men and women with NAFLD were higher (38.53±0.31 cm and 35.83±0.48 cm, respectively) than those without NAFLD (33.58±0.24 and 31.098±0.14 cm, respectively) (p<0.001). Metabolic markers including age, weight, BMI, NC, WC, WHR, FBS, triglycerides were significantly higher, HDL was significantly lower among participants with NAFLD compared to those without NAFLD (p<0.05). NC was independently associated with NAFLD among women with OR (95%CI) of 1.17 (1.05, 1.32). The optimal cut-offs of NC to predict NAFLD were 37.07 cm (sensitivity: 70.50%; specificity: 68.90%) and 32.07 cm (sensitivity: 70.70%; specificity: 62.10%), respectively for men and women. NC significantly correlated with NAFLD in women. The optimal cut-off points of 32 cm and 37 cm for men and women, which similar to Chinese populations. Therefore, it can be used as a cost-effective tool to predict NAFLD. Trial Registration: Thai Clinical Trials Registry (TCTR20210329006)
