A Study on the Correlation between the Income of Chinese Population and Non-alcoholic Fatty Liver Disease

Objective The study was to analyze the correlation between the income of the Chinese population and non-alcoholic fatty liver disease (NAFLD). Method 930 subjects were divided into three groups according to their liver fat content (LFC). (1) normal group: LFC 20% 201 cases. All participants' clinical and social background were collected, including fasting routine test for related index. We compared the differences among the three groups with one way ANOVA, to analyze the relation between the income and each index with Pearson correlation, for the independent factors of LFC with Binary logistic regression. Results (1) Within the retirees, the prevalence rate of female NAFLD (81.2%) was greater than the male (75%), however, falling with age: the highest was between 40 to 49 years old (87.5%), while the lowest occurred above 70 years old (68%). (2) The incomes of the subjects were positively correlated with TG, SUA and LFC (P 5000RMB). Thus, to increase the income without improving education level or health awareness, the prevalence rate of NAFLD will get higher.
