Abstract:

Objective     To analyze the prevalence rate of nonalcoholic fatty liver disease (NAFLD) and its influential factors in railway workers. Methods     12094 physical examination results of Jinan railway workers in 2008 were involved. Single factor analysis and multivariate logistic regression analysis were used. Results     The prevalence rate of NAFLD in railway workers was 33.8%, and there were significant differences in the prevalence rate among different age and gender groups. Single factor analysis showed that smoking, alcohol, and high levels of blood pressure (BP), fasting plasma glucose (FPG), triglycerides (TG) and body mass index (BMI) were the risk factors of NAFLD; multivariate logistic regression analysis showed that gender, age, smoking, alcohol, abnormal FPG, high TG, and high BMI were the risk factors of NAFLD. Conclusion    The prevalence rate of NAFLD is at a high level and the prevention and treatment of NAFLD in railway workers should be strengthened.
