To examine the role of delayed childbearing in the prevention of obstetric fistulas (OFs).
Data on 4798 deliveries in Niger (1995-1998), 3552 in Nigeria (1996-1999), and 6789 in Tanzania (1991-1996) were analyzed with logistic regression models.
Young maternal age and primiparous status were identified as correlates of prolonged/obstructed labor. The annual incidence of OFs in Nigeria was found to be 2.11 per 1000 births, with 9817 cases developing each year, 28% in women and girls younger than 20 years. The predicted proportion of women experiencing prolonged/obstructed labor would be reduced by 11.2% in Niger, 11.4% in Nigeria, and 13.1% in Tanzania if the risks associated with young maternal age at first delivery and primiparity were eliminated.
Community programs to educate young, newly married women about delaying childbearing until they reach physical maturity should be implemented in countries with a high incidence of OFs.
探讨晚育在预防产科瘘管病（OFs）中的作用。
采用逻辑回归模型分析了尼日尔（1995 - 1998年）4798例分娩、尼日利亚（1996 - 1999年）3552例分娩以及坦桑尼亚（1991 - 1996年）6789例分娩的数据。
年轻产妇年龄和初产状态被确定为产程延长/梗阻性分娩的相关因素。尼日利亚产科瘘管病的年发病率为每1000例分娩中有2.11例，每年有9817例发病，其中28%发生在20岁及以下的妇女和女孩中。如果消除首次分娩时产妇年龄小和初产相关的风险，预计尼日尔产程延长/梗阻性分娩的妇女比例将降低11.2%，尼日利亚降低11.4%，坦桑尼亚降低13.1%。
在产科瘘管病高发国家，应实施社区项目，教育年轻的新婚妇女推迟生育，直至身体发育成熟。
