Objective To investigate the serological patterns of hepatitis B, understand the prevalence of hepatitis B infection in neonates, infants and preschool children based on hospital data in Zhejiang province and provide a basis for prevention and control of local pediatric hepatitis B infection. Methods Five serological markers were detected on electrochemiluminescence analyzer Roche E601. The results of all serological markers in children with hepatitis B from 2006 to 2010 were exported from laboratory information system and 24 892 (15 810 boys and 9 082 girls) cases were selected for further analysis according to the exclusion criterion including duplicate analysis, children older than 7 years and children living out of Zhejiang province. SPSS13.0 software and EXCEL 2003 were employed for statistical analysis in this study. Results Average HBV vaccination coverage rates among 15 413 boys and 8 840 girls were 99. 16%(98. 87% -99. 45%) and 99. 17% (98. 29% -99. 53%), respectively. Seventeen serological patterns of hepatitis B were observed, and "anti-HBs(+)alone"(64. 997%) was the dominant patterns followed by "negative" (18. 231%), "anti-HBc(+)anti-HBs(+)"(9.911%) and "anti-HBe(+)antiHBc(+) anti-HBs(+)"(4.395%), and the positive rates for other patters were 0. 004% -0. 992%. There were significant difference of detection rates for "anti-HBc(+)alone" and "anti-HBe(+)anti-HBs(+)"patterns between male and female (χ2=7.143,8.123, all P<0.01), and there were no significant difference of detection rates for the other 15 patterns between male and female (all P >0.05). Ninety-four HBsAg positive cases were detected, accounting for 0.38%. Totally 19 899 anti-HBs positive cases were detected, accounting for 79.94%. Totally 16 187 cases were "anti-HBs(+) alone", accounting for 81.3%of the total anti-HBs(+) cases. The group of 1-2 years and 2 day-2 week had the highest and lowest rate for anti-HBs(+)alone respectively. The ratios in three groups with different anti-HBs levels (10-100 mIU/ml,100-1000 mIU/ml and > 1000 mIU/ml) in 16 178 anti-HBs(+) children were 23. 64%, 27.66% and 13. 70%, respectively. Totally 3 904 cases with anti-HBc(+) were detected, accounting for 15.68%. The highest positivity rate and lowest positivity rate were in the group of 2-4 week and 3-4 week respectively. In total 1 565 cases with negative results, the lowest negativity rate and highest negativity rate were in the group of 9-12 month (3. 25%) and 6-7 age (36. 21%) respectively. Conclusions The dominant serological patterns of hepatitis B in local young children is "anti-HBs (+) alone" and most of the anti-HBs concentrations ranged from 100 to 1000 mIU/ml, followed by "negative". The total positive rate of HBsAg is mild. The rate of hepatitis B serological patterns in children is associated with ages but independent of gender. For interpretation of serological patterns of HBV in children below 12 months (especially in 3 months) the status of their mothers' HBV infection should also be taken into consideration.
