Abstract

high frequency of animal oil (odds ratio = 1.71, 95% confidence interval: 1.11–2.63, for high vs. low intake) and high intake of oil were positively related to non-alcoholic fatty liver disease (odds ratio: 2.00; 95% CI: 1.04– 3.82), while high consumption of tea was associated with a decreased risk (odds ratio: 0.57; 95% confidence interval: 0.36–0.90). For both males and females, results of relationship between non-alcoholic fatty liver disease and anthropometric and biochemical measurements showed that incremental triglyceride was related to an increased risk of non-alcoholic fatty liver disease with the highest odds ratios (2.24 for males and 1.88 for females, respectively). Conclusion Non-alcoholic fatty liver disease in adults was highly prevalent in the Beijing community. High consumption of tea was associated with a decreased risk of non-alcoholic fatty liver disease, while high frequency of animal oil, high intake of oil and triglyceride were positively related to non-alcoholic fatty liver disease. These findings need to be confirmed in prospective studies and randomised controlled trials designed to further clarify the pathogenesis of non-alcoholic fatty liver disease and to establish evidence-based dietary recommendations for its prevention and treatment.
