Objective The purpose of this study was to explore the similarities and differences between nonalcoholic fatty liver (FL) disease (NAFLD) and abdominal obesity in their association with insulin resistance and metabolic syndrome (MetS). Methods The Survey on Prevalence in East China for Metabolic Diseases and Risk Factors (SPECT‐China) is a population‐based survey of Chinese adults. A total of 9,685 participants (median age, 53 years; interquartile range, 44‐63) were grouped into four categories by waist circumference (WC) and NAFLD status: NWC/FL(−), NWC/FL(+), HWC/FL(−), and HWC/FL(+) [FL(−), without NAFLD; FL(+), with NAFLD; HWC, higher WC; NWC, normal WC]. Logistic regression models were used to obtain the odds ratios as estimates of the associations between different categories and MetS. Results Male participants with HWC/FL(−) had higher homeostatic model assessment for insulin resistance scores than subjects with NWC/FL(+), but female subjects showed the opposite results. Compared with NWC/FL(+), HWC was associated with an increased likelihood of blood pressure disorder and a decreased likelihood of triglyceride and blood glucose disorders in men, but in women, HWC was associated with only a lower likelihood of triglyceride disorder. Despite these differences, patients with NWC/FL(+) and HWC/FL(−) had almost equally serious degrees of metabolic disorders (MetS z score). Conclusions There are significant differences between sexes regarding the association between NAFLD and abdominal obesity status and MetS components.
