为了解云南省贫困山区儿童乙型肝炎 (乙肝 )疫苗接种率及乙肝病毒表面抗原 (HBsAg)携带状况 ,对寻甸回族彝族自治县和景东彝族自治县进行调查 ,结果显示 :两个县 1995～ 1999年和 2 0 0 0年产妇住院分娩率分别为4 3 77%和 5 1 6 3%。 1995～ 1999年和 2 0 0 0年出生儿童乙肝疫苗在出生后 4 8h内首针及时接种率分别为 1 6 9%和 31 4 8% ,新生儿乙肝疫苗接种率分别为 3 74 %和 4 6 0 7% ,乙肝疫苗 3针全程免疫接种率分别为 30 4 3%和79 6 5 %。实施中国肝炎防治基金会乙肝疫苗扶贫项目后 ,2 0 0 0年出生儿童乙肝疫苗首针及时接种率、新生儿乙肝疫苗接种率、乙肝疫苗 3针全程免疫接种率 ,均有明显提高。 1995～ 1999年出生儿童及其母亲HBsAg阳性率分别为 1 0 7%和 3 74 % ,2 0 0 0年出生儿童及其母亲HBsAg阳性率分别为 1 15 %和 3 4 5 %。
In order to understand the hepatitis B (hepatitis B) vaccination rate and HBsAg carrier status of children in impoverished mountainous areas in Yunnan Province, we investigated the Xundian Hui Autonomous County and the Jingdong Yi Autonomous County. The results showed that: Hospital delivery rates in males and females in 2004 and 2007 were 43.77% and 51.63% respectively. Hepatitis B vaccine born in 1995 ~ 1999 and 2000 in the first 48 hours after birth, the first-dose timely vaccination rates were 1.69% and 31.48%, neonatal hepatitis B vaccination rates were 3 74% and 4 6 0 7%. The 3-dose whole-dose immunization rate of hepatitis B vaccine was 30 4 3% and 79 6 5% respectively. After the implementation of Hepatitis Prevention and Treatment Foundation’s Hepatitis B Vaccine Poverty Alleviation Project, the timely introduction rate of the first needles of hepatitis B vaccine, the vaccination rate of newborn’s hepatitis B vaccine and the 3-needle full immunization rate of hepatitis B vaccine were all significantly increased. The positive rates of HBsAg between born children and their mothers in 1995-1999 were 107% and 374% respectively. The positive rates of HBsAg in children and their mothers in 2000 and 1999 were respectively 115% and 345%.
