To analyze the prevalence of non-alcoholic fatty liver disease (NAFLD) and its influencing factors, and to explore the role of residual lipoprotein (RC) in risk assessment of NAFLD in the elderly.
The elderly over 60 years old in Xinzheng city, Henan Province in 2021 were selected as the research subjects, and the basic information, physical examination data, and laboratory indexes were collected. The role of RC in risk assessment of NAFLD in the elderly population was investigated by t test, χ2 test, and multivariate Logistic regression analysis with the use of SPSS 26.0 software and R4.2.2.
A total of 62 730 elderly people were included in this study, and the prevalence rate of NAFLD was 26.02%. In univariate analysis, with the increase of RC level, the prevalence rate of the elderly population increased steadily, with the lowest in the first quartile and the highest in the second quartile (23.77% and 30.43%, respectively). Multivariate Logistic regression showed that the risk of NAFLD in women was 1.728 times higher than that in men (95%CI: 1.607-1.858), and the increase of age, BMI,waist circumference, fasting blood-glucose (FBG), triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol(LDL-C), and RC increased the risk of NAFLD. For every unit increase in RC, the risk of disease increased by 56.30% (95%CI:1.433-1.704), and after adjusting for confounding factors, RC was still a risk factor for NAFLD.
The prevalence of NAFLD is high in the elderly, and there is an independent correlation between RC and NAFLD.
