A Study on the Trend of Hepatitis B Positive Prevalence Rate in a steel manufacturing company - Result on Surveys from 1998 to 2002 -

The 5 year follow up study was conducted to assess the positive seroprevalence of HbsAg and magnitude of new cases in a steel manufacturing big scale workpalce. About 2,000 serum samples collected from 1998 to 2002 for hepatititis B surface antigen(HBsAg), antibody to HBsAg(anti-HBs), sAST, sALT, r-GTP, total cholesterol, and triglyceride were tested. The commercially available enzymelinked immunosorbent assay was utilized in serologic test of hepatititis B surface antigen (HBsAg), and antibody to HBsAg(anti-HBs). The preceived seroprevalence rates in the study were ranged 6.3～6.9%. The seroprevalences of HbsAg were 4.3～4.9% among the age of thirties, a significantly decreased seroprevalence compared with those among other age groups(in forties, 7.1～8.2%, and in fifties 7.1～7.6%). The positive seroprevalence of anti-HBs were 71.0～77.9%. A new case was not detected in the group.
