为了解乡村≤ 15岁人群乙型肝炎 (乙肝 )疫苗接种率及乙肝病毒表面抗原 (HBsAg)阳性现状 ,于 2 0 0 2年采取整群抽样法 ,对全县 14个乡村 35 786名≤ 15岁人群 ,用胶体金试纸快速检测方法进行了乙肝疫苗接种率调查及HBsAg检测。结果显示 :乡村≤ 15岁人群乙肝疫苗接种率为 5 1 6 0 % ,0～ 3岁、4～ 7岁、8～ 12岁、13～ 15岁人群接种率分别为 74 10 %、6 1 2 4 %、4 9 35 %、37 39% ,各年龄组人群接种率差异有非常显著的统计学意义 ;HBsAg阳性率为 17 93% ,0～ 3岁、4～ 7岁、8～ 12岁、13～ 15岁人群HBsAg阳性率分别为 7 94 %、10 93%、19 70 %、2 5 2 9% ,各年龄组人群HBsAg阳性率差异有非常显著的统计学意义 ;有接种史和无接种史人群HBsAg阳性率分别为 11 34%和 2 4 96 % ,差异有非常显著的统计学意义 ;0～ 3岁、4～ 7岁、8～ 12岁有接种史人群HBsAg阳性率分别为 1 75 %、4 73%、12 5 2 % ,均非常显著低于同年龄组无接种史人群 ,13～ 15岁人群有无接种史HBsAg阳性率差异无显著的统计学意义。提示需进一步提高新生儿乙肝疫苗接种率 ,对大年龄组人群进行血清学检测 ,对适宜接种对象进行预防接种。
In order to understand the hepatitis B (hepatitis B) vaccination rate and the positive status of hepatitis B virus surface antigen (HBsAg) in the rural population aged ≤ 15 years, a cluster sampling method was adopted in 2002, and 35 786 ≤ 15 Year-old population, rapid test methods using colloidal gold test for hepatitis B vaccine coverage and HBsAg detection. The results showed that the vaccination rate of hepatitis B vaccine was 51.6% in rural areas ≤ 15 years old, 0 to 3 years old, 4 to 7 years old, 8 to 12 years old, and the vaccination rates of 13 to 15 years old groups were 74 10% and 61 2 The prevalence of HBsAg was 17 93%, 0-3 years, 4-7 years old, 8-12 years old, The positive rates of HBsAg in 13 ~ 15-year-old population were 794%, 1093%, 1970% and 259% respectively. There was significant difference in HBsAg positive rate among all age groups. The positive rates of HBsAg in the history population were 11 34% and 24 96%, respectively, and the difference was statistically significant. The positive rates of HBsAg in 0-3 years old, 4-7 years old and 8-12 years old group were 1 75 %, 4 73% and 125 2%, respectively, were significantly lower than those in the same age group with no history of vaccination. There was no significant difference in the positive rate of HBsAg between the ages of 13 and 15 in the vaccination history. Prompted to further improve the neonatal hepatitis B vaccination rates, serological detection of large age groups, the appropriate vaccination against vaccination.
