Abstract

Objective  To investigate the prevalence of metabolic associated fatty liver disease (MAFLD) and its influencing factors in an administrative district of Wuhan. 

Methods  The study in-cluded 20,502 residents aged 65 years or older receiving a free physical examination in this area in 2018. The prevalence of MAFLD among different genders, ages and BMI grades were compared. Uni-variate analysis was performed using the χ2 test and the OR with associated 95% CI for MAFLD was cal-culated using the multivariate non-conditional logistic regression method. 

Results The prevalence of MAFLD was 38.75%, being higher in women than men (41.44% vs. 35.53%), and those aged 65~69 years had the highest prevalence (40.91%). The prevalence of MAFLD also showed an increasing trend with increasing BMI (P<0.001). The Logistic regression results showed that, after adjusting for age, gender and education levels, drinking alcohol [OR=1.348, 95%CI(1.181, 1.539)], dyslipidemia [OR=1.769, 95%CI(1.655, 1.891)], hypertension [OR=1.354, 95%CI(1.259, 1.456)], overweight/obesity [OR=4.859, 95%CI(4.476, 5.274)], central obesity [OR=2.517, 95%CI(2.348, 2.698)], ALT abnormity [OR=2.223, 95%CI(1.906, 2.592)] and impaired fasting glucose [OR=1.485, 95%CI(1.346, 1.638)] may be risk factors for the increased prevalence of MAFLD. 

Conclusion The prevalence of MAFLD among residents aged 65 years and older is high in this district. We should enhance health education and con-trol alcohol consumption. Besides, targeted interventions should be implemented for residents with dyslipidemia and hypertension, and for those elderly residents with overweight/obesity and central obesity. Routine monitoring of people with abnormal ALT and impaired fasting blood glucose also needs to be increased.
