摘　　要：目的了解重庆市长寿区2002年以前出生的学龄前儿童乙型肝炎（下称乙肝）疫苗接种率及乙肝表面抗原（HBsAg）携带率。方法随机抽取该城区适龄儿童267例、农村儿童248例进行调查。结果该区3-6岁儿童乙肝疫苗接种率为72．23％，首针及时接种率为62．14％，全程接种率为65．45％，全程及时接种率为53．20％；城市儿童的几项接种率均明显高于农村儿童（X^2=56．42、31．97、35．94和9、00，P〈0.005）；城市儿童HBsAg携带率明显低于农村儿童（X^2=4．00，P〈0．05）。结论乙肝疫苗纳入计划免疫后如何提高农村地区儿童的接种率，是今后工作的重点。Objective To investigate the inoculation rate of hepatitis B vaccine and HBsAg carrier rate in preschool children born before 2002 in Changshou District, Chongqing City. Methods 267 targeted children in urban area （urban group） and 248 in rural area （rural group） were enrolled in the investigation by random sample method. Results The inoculation rate of hepatitis B vaccine was 72.23% in children aged 3 to 6, the timely inoculation rate of the first dose of hepatitis B vaccine for newborns was 62.14%, whole range inoculation rate was 65.45%, and whole range timely inoculation rate was 53.20%. The above inoculation rates were much higher in urban group than those of rural group （X^2 =56.42, 31.97, 36.94 and 9.00,P〈0. 005）, whereas the CHBsAg carrier rate was signifi- cantly lower in urban group than that of rural group （X^2=4.00,P〈0.05）. Conclusion How to improve the inoculation rate of hepatitis B vaccine of children living in rural area is the focal point in the future with the background that HB vaccine is adopted into Expanded Programme on Immunization （EPI）.
