The current study aimed to investigate the association of MAP with non-alcoholic fatty liver disease (NAFLD) and to explore the differences in this association across populations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study used data from the NAGALA study from 1994 to 2016. MAP was calculated as 1\/3 systolic blood pressure (SBP)\u2009+\u20092\/3 diastolic blood pressure (DBP). Restricted cubic spline (RCS) and logistic regression models were used to examine the correlation of MAP with NAFLD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study population was 14,251 general people undergoing health screening, with a median (interquartile range) age of 42 (36\u201350) years; among them, 48% were women, and 2,507 (17.59%) were diagnosed with NAFLD. After fully controlling for confounders in the current dataset, MAP was positively and non-linearly associated with NAFLD [(odds ratios (ORs): 1.39, 95% confidence intervals (CIs): 1.15, 1.68); <jats:italic>P<\/jats:italic> for non-linearity\u2009=\u20090.024]; the dose-response curve showed that there was a transient saturation effect interval when MAP was between 85 and 95\u2005mmHg, where the risk of NAFLD was neither increased nor decreased. The results of the stratified analysis showed that the risk of NAFLD associated with MAP appeared to be influenced only by age (<jats:italic>P<\/jats:italic>-interaction\u2009=\u20090.002), but not by sex, body mass index (BMI), habits of exercise, drinking status, or smoking status (<jats:italic>P<\/jats:italic>-interaction\u2009&amp;gt;\u20090.05); further age-stratified RCS analysis showed that the non-linear association between MAP and NAFLD in the young and middle-aged and the middle-aged and elderly populations was consistent with the results of the whole population, whereas, in the elderly population, a U-shaped curve association between MAP and NAFLD was observed, with both low and high MAP increasing the risk of NAFLD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In the general population, MAP was positively and non-linearly associated with NAFLD, and this association only differed significantly by age, but not by sex, BMI, habits of exercise, drinking status, and smoking
