Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases with a high prevalence in the general population. The association between NAFLD and cardiovascular disease has been well addressed in previous studies. However, whether NAFLD is associated with carotid artery disease in a community-based Chinese population remained unclear. The aim of this study was to investigate the association between NAFLD and carotid artery disease.
Methods: A total of 2612 participants (1091 men and 1521 women) aged 40 years and older from Jidong of Tangshan city (China) were selected for this study. NAFLD was diagnosed by abdominal ultrasonography. The presence of carotid stenosis or plaque was evaluated by carotid artery ultrasonography. Logistic regression was used to analyze the association between NAFLD and carotid artery disease.
Results: Participants with NAFLD have a higher prevalence of carotid stenosis (12.9% vs. 4.6%) and carotid plaque (21.9% vs. 15.0%) than those without NAFLD. After adjusting for age, gender, smoking status, income, physical activity, diabetes, hypertension, triglyceride, waist-hip ratio, and high-density lipoprotein, NAFLD is significantly associated with carotid stenosis (odds ratio [OR]: 2.06, 95% confidence interval [CI]: 1.45–2.91), but the association between NAFLD and carotid plaque is not statistically significant (OR: 1.10, 95% CI: 0.8–1.40).
Conclusion: A significant association between NAFLD and carotid stenosis is found in a Chinese population.
结果：患有非酒精性脂肪肝的受试者中颈动脉狭窄患病率（12.9％vs 4.6％）和颈动脉斑块患病率（21.9％vs 15.0％）均高于未患有非酒精性脂肪肝的受试者。在调整年龄，性别，吸烟状况，收入，体力活动，糖尿病，高血压，甘油三酯，腰臀比和高密度脂蛋白等因素后，我们发现非酒精性脂肪肝与颈动脉狭窄显著相关(OR: 2.06, 95% CI: 1.45-2.91)，但非酒精性脂肪肝与颈动脉斑块之间的关联却无统计学意义(OR: 1.10, 95% CI: 0.86-1.40)。
