ABSTRACT
Workers', periodic health examination is the main tools used to manage the health problems of most workers in Korea. The most common health problem found in workers' periodic health examination is liver disorder. Liver disorder is also one of the most common health problems in general population and one of the leading causes of mortality in adult population. Regulation proposed by government(NO. 207, Ministry of Labor, 1992) defines the criteria for selection of workers with the liver dysfunction for further evaluative examination and the examination items used for diagnosis of the workers with liver dysfunction. This study was designed to evaluate the proficiency of each examination items presently defined in Regulation and propose the optimal examination items for detection of the liver disorders found by workers' periodic health examination. Study subjects are 186 workers with abnormal liver function tests in screening examination of workers' periodic health ex amination. Questionnaire survey including past history of liver disorder, drinking history, height and weight was done. Physical examination by physician, routine test items defined by Regulation (SGOT, SGPT, gamma- GTP, protein, albumin, total and direct bilirubin, alkaline phoshatase, alpha-feto protein, HBsAg and anti-HBs), anti-HCV antibody test and liver ultrasonography were done. Results are as follows; 1. Result of evaluative examination utilizing only the items defined in Regulation was; There were 75 workers with suspected liver disorder(40.3%), 63 with no liver dysfunction(33.90%), 13 with suspected hepatitis B(7.0%), 10 workers with hepatitis B(5.4%) 10 workers with hepatitis B carrier state(5.4%), 10 with alcoholic liver disorders(5.4%), 5 with fatty liver(2.7%). When alternative diagnostic criteria applying additional examination items (drinking history, body mass index, anti-HCV antibody and ultrasonography) diagnosability of liver disorder was increased. When all four items were included, final results were; 23 workers (l7.8%) with hepatitis B(10 carriers, 13 suspects and 10 hepatitis B), 10(5.4%) with hepatitis C(4 carriers, 5 suspects and 1 hepatitis C), 13(7.0%) with alcoholic liver disorder, 45 (24.2%) with fatty liver (40 suspects, 5 fatty liver), 41 0%) with suspected liver disorders and 44(23.7%) with normal liver. 2. Of examination items defined by Regulation, only SGOT, SGPT, gamma-GTP and HBsAg were significantly different in abnormal rate and mean value, and all other laboratory findings did not showed significant difference between two groups. Drinking history, body mass index and anti-HCV antibody test which are the items that authors included in this study, also showed significant difference between two groups. Utilization of body mass index(BMI) for abnormal liver function group in diagnosis of fatty liver had high specificity(97.6%) but sensitivity (22.3%) was low. Therefore we suggest that SGOT, SGPT, gamma-GTP, HBsAg, alcohol drinking history, BMI and anti-Hcv Ab were useful for diagnosis of liver disorders among worker's periodic health examination.
Key words: workers' periodic health examination; liver disorder; hepatitis C; fatty liver
