- Abstract: Objective To investigate the association between plasma atherogenic index of plasma(AIP)and metabolism-associated steatotic liver disease(MASLD),and to evaluate the potential value of AIP as a predictive marker for MASLD risk.Methods We enrolled a total of 4 850 health check-up participants from The Second Affiliated Hospital of Xi'an Jiaotong University between June 2021 and May 2023.The participants were divided into quartiles(Q1-Q4)according to their AIP level.Biochemical indicators and MASLD prevalence were compared across groups.Logistic regression,subgroup analysis,and restricted cubic splines(RCS)were used to explore the relationship between AIP and MASLD.Results Among the 4 850 participants,the prevalence of MASLD was 26.08％(1 265/4 850).MASLD prevalence increased across AIP quartiles:4.0％,13.8％,30.8％,and 55.6％in Q1-Q4,respectively(P＜0.001).Compared with Q1,Q2-Q4 groups showed higher proportions of males,BMI,smokers,overweight/obesity,central obesity,prediabetes,hypertension,serum uric acid,and fatty liver index(FLI)(all P＜0.001).Lipid profiles worsened with increased AIP:total cholesterol,triglycerides,and LDL-C increased,while HDL-C decreased(P＜0.001).RCS analysis demonstrated a significant linear relationship between AIP and MASLD risk.After adjusting for confounders,the participants in Q4 had an 8.71-fold higher risk of MASLD than those in Q1(OR:8.71,95％CI:6.20-12.23,P＜0.001).A composite model incorporating AIP,BMI,and FLI showed superior discriminative performance(AUC:0.883,95％CI:0.873-0.892).Interaction analysis suggested that AIP had significant interactions with BMI,hypertension,and prediabetes(P＜0.05).In individuals without these metabolic abnormalities,the association between AIP and MASLD was more pronounced.Conclusion Elevated AIP was significantly associated with an increased risk of MASLD,with a stronger association observed in individuals with normal BMI,blood pressure,and blood glucose levels,suggesting that AIP may serve as a potential indicator for early screening of MASLD.
