| Objective: Analyze fatty liver disease(FLD)prevalence rate of health check-up crowd with different occupations and its influencing factors; Explore the influence of different occupations to FLD prevalence rate and its associated risk factors such as weight, blood lipid, blood pressure, blood glucose, and metabolic disorders; Provide scientific basis for the prevention and control of the disease.Methods:1 Choose the physical examination data of four different groups of occupation from a hospital from January 2014 to December 2014. There are 8250 cases totally. Then, randomly select the male physical examinees from 36 to 55 years old and eliminate examinees with coronary artery, active hepatitis cirrhosis and examinees with disorder related laboratory test data as the research object with a total number of 1319 cases, in which, 346 cases of agency personnel, 332 cases of company white-collar worker, 341 cases of scientific research personnel and 300 cases of workers are included.2 All the object of study will be measured height, weight, systolic pressure and diastolic pressure and be inquired medical history by professional trained medical staff. They will also accept abdominal ultrasound, fasting blood glucose, blood lipid, liver result examination, etc.3 To compare FLD prevalence rate situations of examinees with different occupation and analyze the influence of different influence factors, such as body mass index, blood glucose, blood lipids, blood pressure, smoking, drinking and so on, on prevalence rate of FLD.4 Use software of Excel2007 and SPSS21.0 for data collection and statistical analysis.Results:1 Situation of FLD prevalence rate of health check-up crowd with different occupationsIn groups of people with different occupation, the FLD prevalence rate of agency personnel, company white-collar worker, scientific research personnel and workers were respectively 59.54%、52.71%、46.92% and 35.00% and the FLD prevalence rate difference of different occupational population was statistically significant(c2=40.499, P<0.05). The FLD prevalence rate of agency personnel was the highest and that of workers was lowest with that of white-collar worker and scientific research personnel in the middle. The result of comparing the FLD prevalence rate of any two groups is that the difference of FLD prevalence rate between workers and that of the other occupational groups is statistically significant, so is the difference of that between agency personnel and scientific research personnel. The difference of that between the other groups is not statistically significant.The different occupational groups are given stratification according to age. It can be seen that the FLD prevalence rate of agency personnel was the highest at any age level and that of worker is the lowest. The FLD prevalence rate peak of agency personnel and company white-collar worker is in the group of 51-55 years old. The FLD prevalence rate peak of scientific research personnel and workers is in the group of 41-50 years old. The FLD prevalence rate difference of any group of weight index, such as normal group, overweight group and obesity group, between different occupational groups is statistically significant. The FLD prevalence rate increased with the increase of body weight index. In the obesity group, the FLD prevalence rate of company white-collar workers is the highest(91.04%) and that of worker is the lowest(76.06%).Smoking just has influence on FLD prevalence rate of agency personnel and company white-collar workers and the difference of that is statistically significant. Drinking has the influence on that of scientific research personnel and the difference is statistically significant.The FLD prevalence rate of different occupational groups increased with the increase of blood pressure, fasting blood glucose and blood lipid(total cholesterol and triglycerides). The FLD prevalence rate of high blood pressure group was 64.06%, which was significantly higher than that of normal blood pressure group(42.20%). Among them, The FLD prevalence rate of agency personnel is the highest(72.36%) and that of scientific research personnel is the lowest(56.19%). The FLD prevalence rate of high blood sugar group was 72.35%, which was significantly higher than that of normal blood sugar group(44.37%). Among them, The FLD prevalence rate of company white-collar workers is the highest(85.37%) and that of scientific research personnel is the lowest(58.23%). The FLD prevalence rate of high total cholesterol group(the company white-collar workers, scientific research personnel and workers) was significantly higher than the normal group, and that of workers is the highest(86.67%). The FLD prevalence rate of agency personnel and workers increased with the increase of triglycerides, in which, that of agency personnel is the highest(71.52%) and that of workers is the lowest(52.24%).2 The Logistic regression analysis of FLD risk factors The multi-factors Logistic regression model is used in the study to regression analyzed step by step. The result shows that occupation, body mass index(BMI), fasting blood glucose(FBG), total cholesterol(TC), triglyceride(TG) and total bilirubin(DBIL) are associated with FLD. Occupation is closely related to the prevalence rate of FLD and is a risk factor for FLD. Among them, the OR value of agency personnel, company white-collar workers and scientific research personnel are respectively 2.537, 2.404, and 1.720 times of that of workers. Age,high blood pressure, alanine aminotransferase(ALT), aspertate aminotransferase(AST), direct bilirubin(TBIL), have no correlation with FLD.Conclusions:1 The FLD prevalence rate of different occupational groups is different. That of agency personnel is the highest and that of workers is the lowest.2 Occupation, obesity, fasting blood glucose(FBG), total cholesterol(TC)and triglyceride(TG) are closely related to the prevalence rate of FLD and the risk factors causing FLD. Age, high blood pressure, ALT, AST, DBIL has no correlation with male prevalence rate of FLD. |
