- Abstract: ObjectiveTo perform metabolic associated fatty liver disease (MAFLD) screening among individuals attending community health institutions, to identify the patients at a low, moderate or high risk of advanced liver fibrosis based on fibrosis-4 index (FIB-4) and liver stiffness measurement (LSM) measured by liver transient elastography, and to implement stratified management. MethodsA cross-sectional study was conducted among 630 individuals attending Beijing Baizhifang Community Health Service Center from January to July 2024, and they were divided into MAFLD group and non-MAFLD group. According to body mass index (BMI), the MAFLD group was further divided into lean MAFLD group (BMI<23 kg/m2) and non-lean MAFLD group (BMI≥23 kg/m2). The above groups were compared in terms of demographic features, laboratory markers, hepatic steatosis, and LSM. Fibrosis risk stratification was performed for MAFLD patients based on FIB-4 and LSM, and a closed-loop management system involving referral to tertiary hospitals and follow-up at community health institutions was implemented. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsThere were 445 individuals (70.6%) in the MAFLD group and 185 individuals (29.4%) in the non-MAFLD group. Compared with the non-MAFLD group, the MAFLD group had a significantly lower proportion of male individuals (χ2=4.299, P<0.05), a significant reduction in the level of high-density lipoprotein cholesterol (Z=3.484, P<0.05), and significant increases in body weight (Z=-7.366, P<0.05), BMI (Z=-9.740, P<0.05), waist circumference (Z=-6.397, P<0.05), hip circumference (Z=-6.935, P<0.05), alanine aminotransferase (ALT) (Z=-2.765, P<0.05), fasting blood glucose (Z=-3.646, P<0.05), triglyceride (TG) (Z=-6.569, P<0.05), total cholesterol (Z=-2.033, P<0.05), low-density lipoprotein cholesterol (Z=-2.935, P<0.05), controlled attenuation parameter (CAP) (Z=-19.784, P<0.05), and LSM (Z=-5.703, P<0.05). Within the MAFLD group, there were 124 individuals (27.9%) in the lean MAFLD group and 321 individuals (72.1%) in the non-lean MAFLD group. Compared with the non-lean MAFLD group, the lean MAFLD group had significantly lower body weight (Z=-12.414, P<0.05), BMI (Z=-16.363, P<0.05), waist circumference (Z=-7.733, P<0.05), hip circumference (Z=-8.595, P<0.05), ALT (Z=-2.835, P<0.05), aspartate aminotransferase (Z=-1.972, P<0.05), TG (Z=-2.407, P<0.05), CAP (Z=-4.429, P<0.05), degree of steatosis (χ2=16.588, P<0.05), and LSM (Z=-3.908, P<0.05). Based on the results of FIB-4 and LSM, 76 patients at a moderate or high risk of liver fibrosis should be referred to a higher-level hospital for further management. ConclusionThe detection rate of MAFLD reaches 70.6% among the individuals attending community health institutions, among whom 76 (17.1%) should be referred to a higher-level hospital. Establishing a liver fibrosis risk stratification and management system based on FIB-4 and LSM among MAFLD individuals in communities provides a practical pathway for chronic disease management and referral system construction in community health institutions.
