  •   Objective  To investigate the clinical and metabolic factors associated with the development and regression of metabolic dysfunction-associated fatty liver disease (MAFLD) in the physical examination population.  Methods  A retrospective observational study was conducted on 6 809 individuals who underwent physical examination in a physical examination institution in Beijing from December 2013 to December 2019, with a mean follow-up time of 52.1±13.5 months. According to the new diagnostic criteria for MAFLD, these individuals were divided into MAFLD group and non-MAFLD group, and the two groups were compared in terms of demographic indicators, body measurement indicators, and laboratory indicators at the first (baseline) and last physical examinations. The two-independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data. A Logistic regression analysis was used to investigate the impact of various observation indicators on the development and regression of MAFLD.  Results  In this study, there were 4 533 individuals (66.6%) in the non-MAFLD group at baseline, among whom 15.6% developed MAFLD at the last physical examination. Compared with the non-MAFLD population, the MAFLD population had significantly higher age (Z=-6.739), number of male patients (χ2=178.534), body weight (Z=-22.302), body mass index (BMI) (Z=-22.818), waist circumference (Z=-23.117), hip circumference (Z=-18.446), systolic blood pressure (SBP) (Z=-13.301), diastolic blood pressure (DBP) (Z=-13.491), fasting blood glucose (FBG) (Z=-11.787), triglyceride (TG) (Z=-16.623), low-density lipoprotein cholesterol (LDL-C) (Z=-10.256), alanine aminotransferase (ALT) (Z=-14.250), aspartate aminotransferase (AST) (Z=-7.481), and proportion of patients with metabolic syndrome (MetS) at baseline (χ2=185.283), and there were more patients with increases in body weight, waist circumference, hip circumference, TG, TC, ALT, and AST at the final physical examination (all P<0.05); these patients had a lower level of HDL-C at baseline (Z=15.416), and there were more patients with a reduction at the last physical examination (P<0.05). There were 2 276 individuals (33.4%) in the MAFLD group at baseline, among whom 23.8% showed regression of MAFLD at the last physical examination. Compared with the population without regression of MAFLD, the population with regression of MAFLD had a significantly younger age (Z=2.185), a significantly higher number of female patients (χ2=0.340), significantly lower levels of body weight (Z=-8.909), BMI (Z=-10.205), waist circumference (Z=-11.183), hip circumference (Z=-7.178), SBP (Z=-3.627), DBP (Z=-3.443), TG (Z=-5.945), ALT (Z=-9.664), and AST (Z=-5.904), and a significantly lower proportion of patients with MetS (χ2=42.082), and there were more patients with reductions in body weight, waist circumference, hip circumference, blood pressure, TG, TC, ALT, and AST at the final physical examination (all P<0.05); these patients had a higher level of HDL-C at baseline (Z=6.778), and there were more patients with an increase at the last physical examination (P<0.05). The multivariate Logistic regression analysis showed that sex and changes in body weight and HDL-C during physical examination were independently associated with the development and regression of MAFLD (all P<0.05).  Conclusion  There is a relatively high prevalence rate of MAFLD among the physical examination population in Beijing, with a higher proportion of male patients. There are significant metabolic disorders and liver function abnormalities, and changes in body weight and HDL-C are the most important predictive indicators for the development and regression of MAFLD.
