Toevaluate the association between insulin resistance and non-alcoholic fatty liver disease (NAFLD) using the insulin resistance metabolic score (METS-IR).
The study included 1 315 participants from the National Health and Nutrition Examination Survey (NHANES) database from 2017 to 2018, including 740 people with NAFLD and 575 people without NAFLD. Multivariate logistic regression analysis was used to assess the association between METS-IR and the risk of developing NAFLD. Restricted cubic spline regression analysis was performed to examine dose-response relationship after adjustment. Finally, receiver operatingcharacteristic curve analysis was conducted to evaluate the diagnostic performance of METS-IR for NAFLD.
The multivariate logistic regression analysis showed that each unit increase in METS-IR was associated with a 7% higher risk of developing NAFLD (OR=1.07; 95% CI:1.02-1.11). When categorizing METS-IR into quartiles, individuals in the highest quartile had a 3.35 times increased risk compared to those in the lowest quartile (OR=4.35;95% CI:1.38-13.75), showing a significant trend (P-trend <0.05). When the cutoff value is 39.767, the area under the ROC curve for METS-IR in diagnosing NAFLD was 0.788 (SE=0.0126; 95% CI:0.764-0.809).
There is a positive correlation between METS-IR and risk of developing NAFLD, suggesting that it could be used as a potential indicator in the diagnosis of NAFLD.
