Abstract:
Objective:Based on the occupational cohort of Beijing Medical Examination Center, to explored the relevant factors of nonalcoholic fatty liver disease (NAFLD), and to provide scientific basis for screening and early diagnosis of NAFLD in high-risk population.Methods:Based on the cohort of occupational population who underwent physical examination in Beijing physical examination center from January to December 2009, the physical examination indexes were collected, and a retrospective survival cohort with a follow-up period of 3 years was established.According to the idea of nested case-control study, each case was randomly matched with the same gender, age and physical examination time in the same month by using the method of random sampling without putting back.Conditional logistic regression model was established by using the matched data.The diagnostic value of related indicators for NAFLD was analyzed by receiver operating characteristic curve (ROC).Results:A total of 1 194 subjects were included, including 684 males (57.3%, 684/1 194) and 510 females (42.7%, 510/1 194). The age was (50.8±11.6) years.The age ranged from 24.0 to 88.0 years.There were 597 patients with NAFLD, including 342 males and 255 females.Logistic regression analysis showed that body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid and urea nitrogen were statistically significant in male model (all P<0.05). Body mass index( OR=1.242, 95% CI 1.143-1.349, P<0.001), hemoglobin( OR=1.034, 95% CI 1.015-1.053, P<0.001), platelet( OR=1.005, 95% CI 1.002-1.009, P=0.005), uric acid( OR=1.004, 95% CI 1.001-1.006, P=0.004), high density lipoprotein cholesterol( OR=0.377, 95% CI 0.184-0.775, P=0.008) and urea nitrogen( OR=0.807, 95% CI 0.693-0.938, P=0.005) were protective factors for NAFLD in male patients..Body mass index( OR=1.552, 95% CI 1.366-1.762, P<0.001), triglyceride ( OR=2.606, 95% CI 1.616-4.204, P<0.001), blood glucose( OR=2.199, 95% CI 1.332-3.631, P=0.002), uric acid( OR=1.005, 95% CI 1.001-1.010, P=0.024) in female model were statistically significant ( P<0.05), and were risk factors for NAFLD in female patients. Conclusion:The incidence rate of NAFLD was different among different gender and age, body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid, urea nitrogen, triglyceride and blood glucose were closely related to the incidence of NAFLD.
