| Abstract: | BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a risk factor for carotid plaque in the general population; however, whether NAFLD is associated with carotid plaque in aged population remains unknown. This cross-sectional study was conducted to evaluate the association between NAFLD and carotid plaque in a Chinese aged population. METHODS: A total number of 12,990 Chinese aged adults (7,685 men and 5,305 women) were included. NAFLD was diagnosed based on the recommendation of Asia-Pacific Working Party on NAFLD and Chinese Association for the Study of Liver Disease and excessive alcohol consumption (weekly alcohol consumption ≤210 g in men and ≤140 g in women) was excluded. Carotid plaque was confirmed by ultrasonography. Potential confounders and biochemical findings were collected at baseline. Logistic regression model was employed to evaluate the association between NAFLD and carotid plaque. RESULTS: The prevalence of carotid plaque was significantly higher in aged participants with NAFLD than in those without NAFLD (22.4% vs. 16.3%, P<0.001). NAFLD is associated with carotid plaque [odd ratio (OR) =1.89, 95% confidence interval (CI): 1.59-2.24], after adjusting for age, gender, BMI, liver and kidney function, glucose level, lipid profiles, and white blood cell (WBC) count. The association between NAFLD and carotid plaque was attenuated when participants with elevated ALT (≥75 IU/L), a history of cardiovascular diseases (CVDs) and obesity were censored although the significant association remained. CONCLUSIONS: NAFLD is associated with carotid plaque in Chinese aged population. |
