The preceding birth technique, an indirect method for estimating early childhood mortality based on ascertaining the survival of previous children, was applied in rural Ethiopia within a system of demographic surveillance. Trained community health workers acted as interviewers and transmission flow of the routine health information system was used for data reporting. Data were collected for a median 12 month period from 39 sampled villages of Ticho district in Arsi region. From 1064 mothers having at least a second birth, the proportion dead of the last birth was 0.138 (95% CI 0.117-0.150), corresponding approximately to the probability of dying between birth and age two. It approximates to an infant mortality rate of about 100 x 1000 live-births. From 974 mothers having at least a higher-order birth, the proportion dead of the second to last birth was 0.203 (95% CI 0.178-0.228), equivalent to the risk of dying between 0 and age 5. In spite of the progressive migration of the surveyed population, the process and the outcome of the study suggest that PBT may well be inserted into a primary health care information system run by trained community health workers.
先前的出生技术是一种基于确定先前子女的存活情况来估计幼儿死亡率的间接方法，该方法在埃塞俄比亚农村地区的人口监测系统中得到应用。经过培训的社区卫生工作者担任访谈员，并利用常规卫生信息系统的传输流程进行数据报告。在阿尔西地区蒂乔区的39个抽样村庄中，数据收集期中位数为12个月。在1064名至少生育过二胎的母亲中，上一胎死亡的比例为0.138（95%置信区间为0.117 - 0.150），大致相当于出生至两岁之间的死亡概率。这近似于每1000例活产中约有100例的婴儿死亡率。在974名至少生育过三胎的母亲中，倒数第二胎死亡的比例为0.203（95%置信区间为0.178 - 0.228），等同于0岁至5岁之间的死亡风险。尽管被调查人群存在逐步迁移的情况，但研究过程和结果表明，先前出生技术很可能可以纳入由经过培训的社区卫生工作者管理的初级卫生保健信息系统。
