目的:探讨元宝山区中小学生乙型肝炎的流病学规律。方法:采用酶联免疫吸附试验,检测血清样本中的HBsAg、HBeAg、抗-HBc的阳性率。结果:中、小学生HBsAg的阳性率分别为4.1％、3.31％;男、女分别为4.23％、3.71％;城、乡分别为3.11％、4.49％。HBsAg、HBeAg、抗-HBc三项皆为阳性的中、小学生阳性率分别为2.26％、2.36％,男、女分别为2.17％、2.36％,城、乡分别为1.30％、2.83％。结论:元宝山区不同学校、不同性别的阳性率差异无显著性意义,但无论HBsAg阳性率,还是HBsAg+HBeAg+抗-HBc指标的阳率农村显著高于城镇。
Objective: To explore the epidemiological rules of hepatitis B in primary and secondary school students in Yuanba Mountain. Methods: The positive rate of HBsAg, HBeAg and anti-HBc in serum samples was detected by enzyme-linked immunosorbent assay. Results: The positive rates of HBsAg in primary and secondary school students were 4.1% and 3.31%, respectively; 4.23% and 3.71% for males and females respectively; 3.11% and 4.49% for urban and rural areas respectively. The positive rates of HBsAg, HBeAg and anti-HBc in all primary and secondary school students were 2.26% and 2.36% respectively, with 2.17% and 2.36% for males and females respectively, and 1.30% and 2.83% for urban and rural areas respectively. Conclusion: There is no significant difference in the positive rates of different schools and different sexes in Yuanbaoshan district, but the positive rate of HBsAg positive rate or HBsAg + HBeAg + anti-HBc index is significantly higher in rural areas than in urban areas.
