Abstract:
Objective
To explore the correlation of serum uric acid (SUA) and serum uric acid/creatinine (SUA/SCr) ratio with metabolic associated fatty liver disease (MAFLD) in young men, and to compare the value of the two in the preliminary screening of MAFLD.
Methods
Demographic data,laboratory results, and imaging data of young males from the physical examination population were collected.The research subjects were divided into Q1~Q4 groups and Q1’~Q4’ groups according to the quartiles of SUA and SUA/SCr ratio, respectively.
Results
A total of 419 subjects were included (147 in MAFLD group and 272 in non-MAFLD group). The MAFLD group had higher age (36 years vs 35 years, P<0.01), body mass index (BMI; 27.05 vs 24.19, P<0.001), systolic blood pressure (128.11 mmHg vs 121.26 mmHg,P<0.001), diastolic blood pressure (77.13 mmHg vs 72.82 mmHg, P<0.001), fasting blood glucose (5.36 mmol/L vs 5.15 mmol/L, P<0.001), triglycerides (1.75 mmol/L vs 1.10 mmol/L, P<0.001), and eGFR(115.44 ml/min vs 102.81 ml/min, P<0.001) levels, but a lower high-density lipoprotein (1.39 mmol/L vs 1.54 mmol/L, P<0.001) level than the non-MAFLD group. There were statistically significant differences in SUA and SUA/Scr between the two groups. In the Q1~Q4 group divided by SUA, the positive rate of MAFLD accounted for 12.9%, 25.2%, 25.9%, and 36.1% of all MAFLD cases, respectively (χ2=24.98, P<0.001). In the Q1’~Q4’ group divided by SUA/SCr ratio, the positive rate of MAFLD was 12.9%, 22.4%, 29.9%, and 34.7%, respectively (χ2=25.60, P<0.001). After adjusting for age, SBP, DBP, BMI, HDL-C, LDL-C, TG,FBG, etc., the risk of MAFLD in the Q4 group was 2.28 times that of the Q1 group (P=0.04), and the risk of MAFLD in the Q4’ group was still 2.94 times that of the Q1’ group (P=0.007). There was no significant difference in the area under the ROC curve between SUA (0.655) and SUA/SCr ratio (0.663) for screening for MAFLD.
Conclusion
SUA and SUA/SCr ratio are both risk factors for MAFLD. The screening value of SUA/SCr ratio for MAFLD is not superior to that of SUA in young men.
