Four cohorts of urban women who delivered a child before reaching age 18 were followed for periods ranging from 6 to 12 years to determine use of abortion and sterilization. The two more recent cohorts had been served by comprehensive service programs. About 40 per cent of each of teh groups used abortion or sterilization to control fertility. Most of the women seeking abortion had no subsequent term or near term deliveries, suggesting that such a request may signal a desire to terminate childbearing, at least for a few years. A high proportion of the young mothers obtained abortions during the second trimister, even for repeat abortion.
对四组在18岁之前生育过孩子的城市女性进行了为期6至12年的跟踪,以确定她们使用堕胎和绝育的情况。最近的两组女性接受了综合服务项目。每组中约40%的女性使用堕胎或绝育来控制生育。大多数寻求堕胎的女性随后没有足月或接近足月分娩,这表明这样的请求可能意味着至少在几年内终止生育的愿望。很大一部分年轻母亲在孕中期进行了堕胎,即使是重复堕胎。
