Material and Methods : Retrospectively, 4210 boys and 2983 girls between 0-18 years who applied to Ankara Gazi Mustafa Kemal State Hospital between January 2009 and June 2014 and were examined for HBsAg and anti- HBs levels by using Micro ELİSA technics were included. Children were categorized into five age groups. Results: 4231 HBsAg levels were measured and HBsAg positivity was found to be 0.80% (34/4231). 64.70% (22/34) of these were male, 35.30%; (12/34) were female. There was no significant relationship between the two groups regarding HBsAg positivity (p=0,389). 2962 anti-HBs levels were measured and anti-HBs seropositivity was found as 75.30% (2231/2962); anti-HBS seropositivity were 73.40%; (1173/1599) for males and 77,60%; (1057/1363) for females. There was significant relationship between two groups regarding antiHBs seropositivity (p=0,011). According to the age groups, seropositivity ratios were found as 78.70% (118/150), 60.60% (260/429), 64.20% (312/486), 85.10% (798/938) and 77.40% (743/960) in first, second, third, fourth and fifth groups respectively; and statistically significant relationship was found between them. Conclusion: Our study is important for evaluating the seroepidemiology of hepatitis B vaccination that has been administered for 16 years and before. It may also be useful for similar studies comparing different regions. }, number={1}, publisher={Ankara Yildirim Beyazit University}
