title: [Shifting in seroprevalence of HBsAg and anti-HCV during recent 10 years in adults resident in Daegu and Gyeongbuk province].
abstract: OBJECTIVE
  There have been only few studies on the population-adjusted seroprevalence of HBV and HCV and on the change of them for more than 10 years in Korea. Therefore, this study was performed to evaluate them at a single health center in Daegu and Gyeongbuk province considering the population composition ratio.
  
  
  METHODS
  We analyzed the seromarkers of HBV and HCV of 6,237 randomly sampled adults who had received health screening at the health promotion center in Dongsan hospital during the periods from year 1997 to 1999 (Period A) and from 2007 to 2009 (Period B).
  
  
  RESULTS
  The seroprevalences of HBsAg, anti-HBs, anti-HBc and anti-HCV were 4.8%, 70.2%, 47.4%, and 0.5%, respectively. There is no difference in the seroprevalence of HBsAg between period A and B. However, downward tendency of prevalence through A to B from 6.8% to 4.5% could be found in 40s, and upward tendency from 4.7% to 6.8% in 50s. As for the seroprevalence of anti-HCV, although there was no difference through A to B, for 50s, it decreasd from 2.0% to 0.3% (p=0.007). However, for 60s, it increased as much as decreasd for 50s.
  
  
  CONCLUSIONS
  The seroprevalence of HBsAg in Daegu/Gyeongbuk province was 4.8% and showed no difference through the time period of 10 years. The seroprevalence of anti-HCV was 0.5% and also showed no difference through the time periods.
