目的 了解海南垦区学生乙肝表面抗原 (HBsAg)携带状况 ,为制定防治乙肝策略提供科学依据。方法 采用RPHA检测。结果 检测学生 30 5 0 9人 ,检出HBsAg 2 777人 ,携带率为 9.11% ;不同单位学生的HBsAg携带在 5 .97%～ 13.12 %之间 ,差异有极显著性 (x2 =2 44.0 7,P <0 .0 0 5 ) ;三个地区农场学生携带率明显高于城市学生 ,差异有极显著性 (x2 =137.2 9,P <0 .0 0 5 ) ;男女携带率分别为 9.63%和 8.46% ,差异有极显著性 ;年龄组间的差异亦有极显著性(x2 =2 44.0 7,P <0 .0 0 5 ) ,携带率随年龄的增长呈上升的趋势。结论 应加强对基层学校学生HBsAg的检测 ,推广使用乙肝疫苗以降低HBV感染率
Objective To understand the status of hepatitis B surface antigen (HBsAg) carrier in Hainan reclamation area and provide a scientific basis for formulating strategies for prevention and treatment of hepatitis B infection. Methods RPHA detection. Results A total of 30 599 students were detected, of whom 2 777 HBsAg were detected, with a carrying rate of 9.11%. HBsAg among students of different units was between 5.97% and 13.12%, with a significant difference (x2 = 2 44.0 7 , P <0.05). The carrying rate of farm students in three areas was significantly higher than that of urban students (x2 = 137.29, P <0.05). The male and female carrying rates were 9.63% And 8.46% respectively. The difference between age groups was also significant (x2 = 2 44.0 7, P <0.05). The carrying rate increased with age. Conclusion It is necessary to strengthen the detection of HBsAg in primary school students, promote the use of hepatitis B vaccine to reduce the HBV infection rate
