    Abstract
  •   Objective  To screen for the patients with metabolic dysfunction-associated fatty liver disease （MAFLD） among the physical examination population， to observe the characteristics of MAFLD patients， and to compare the differences in lifestyle between the MAFLD population and the non-MAFLD population.  Methods  A cross-sectional study was conducted among 6 206 individuals who underwent physical examination in a physical examination institution in Beijing from December 2015 to December 2019， and according to the new diagnostic criteria for MAFLD， the examination population was divided into MAFLD group and non-MAFLD group. Based on body mass index （BMI）， the MAFLD group was further divided into lean MAFLD group （BMI<24 kg/m2） and non-lean MAFLD group （BMI ≥24 kg/m2）. Related data were compared between groups， including demographic indicators， education level， work pressure， physical measurement indicators， and lifestyles such as sleep， diet， and exercise. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups.  Results  Of all individuals in this study， 1 926 （31.1%） had MAFLD and 4 280 （68.9%） did not have MAFLD. Compared with the non-MAFLD group， the MAFLD group had significantly higher age （Z=-14.459， P<0.001）， proportion of male patients （χ2=72.004， P<0.001）， work pressure （χ2=7.744， P=0.005）， body weight （Z=-43.508， P<0.001）， BMI （Z=-47.621， P<0.001）， waist circumference （Z=-48.515， P<0.001）， hip circumference （Z=-42.121， P<0.001）， and waist-hip ratio （Z=-43.535， P<0.001）， as well as a significantly lower education level （χ2=33.583， P<0.001）. In terms of behavior， the MAFLD group had a significantly shorter sleep time （χ2=5.820， P=0.016） and a significantly faster eating speed （χ2=74.476， P<0.001）. In terms of diet， the patients in the MAFLD group consumed more high-sodium， high-sugar， and high-calorie diets （χ2=42.667， P<0.001） and low-fiber diet （χ2=4.367， P=0.008）. In terms of exercise， the MAFLD group had a significantly higher proportion of patients without exercise habits （χ2=10.278， P=0.001）. Further analysis showed that there were 202 individuals （10.5%） in the lean MAFLD group and 1 724 （89.5%） in the non-lean MAFLD group. Compared with the non-lean MAFLD group， the lean MAFLD group had significantly higher age （Z=3.368， P=0.001） and education level （χ2=9.647， P=0.002） and significantly lower proportion of male patients （χ2=27.664， P<0.001）， body weight （Z=-18.483， P<0.001）， BMI （Z=-23.286， P<0.001）， waist circumference （Z=-18.565， P<0.001）， and hip circumference （Z=-18.097， P<0.001）， and in terms of behavior， the non-lean MAFLD group had a significantly faster eating speed （χ2=4.549， P=0.033）.  Conclusion  There is a relatively high prevalence rate of MAFLD among the physical examination population in Beijing， with a higher number of people with unhealthy lifestyles compared with the non-MAFLD population.
