The study aimed to assess the determinants of immunization coverage in 12-23-month-old children born in 1997 and living in Gansu Province in West China. The World Health Organization's cluster sampling technique was used. Information was gathered by face-to-face interviews with caregivers and from immunization records. Bacille Calmette Guerin (BCG), Polio and Diphtheria, Tetanus, Pertussis (DTP) coverage at 3 months was 51.2%. At 8 and 12 months, including the Measles Vaccine, coverage was 71.3 and 86.0%, respectively. The variables associated with delay at 12 months were: low socio-economic level, low number of sources of information on vaccination and delayed immunization at 3 months. Improved immunization coverage could be achieved by improving access and delivery to poor and remote areas and by awarding incentives to providers at primary care level.
该研究旨在评估1997年出生且居住在中国西部甘肃省的12至23个月大儿童的免疫接种覆盖率的决定因素。采用了世界卫生组织的整群抽样技术。通过与看护者进行面对面访谈并从免疫接种记录中收集信息。3个月时卡介苗（BCG）、脊髓灰质炎疫苗以及白喉、破伤风、百日咳混合疫苗（DTP）的接种覆盖率为51.2%。在8个月和12个月时，包括麻疹疫苗在内，接种覆盖率分别为71.3%和86.0%。与12个月时延迟接种相关的变量有：社会经济水平低、疫苗接种信息来源数量少以及3个月时免疫接种延迟。通过改善贫困和偏远地区的可及性与服务提供，并对基层医疗服务提供者给予激励措施，可提高免疫接种覆盖率。
