Our goal was to determine stillbirth rates in a multisite population-based study in community settings in the developing world.
Outcomes of all community deliveries in 5 resource-poor countries (Democratic Republic of Congo, Guatemala, India, Zambia, and Pakistan) and in 1 mid-level country (Argentina) were evaluated prospectively over an 18-month period. Births of > 1000 g with no signs of life were defined as stillbirth.
Outcomes of 60,324 deliveries were included. Stillbirth rates ranged from 34 per 1000 in Pakistan to 9 per 1000 births in Argentina. Increased stillbirth rates were associated significantly with lower skilled providers, out-of-hospital births, and low cesarean section rates. Maceration was present in 17.2% of stillbirths.
The stillbirth rates among births of > or = 1000 g in these developing countries were substantially higher than reported stillbirth rates in developed countries (3-5/1000 births). Because most developed countries define stillbirth as > or = 20 weeks of gestation or > or = 500 g and because almost one-half of all stillbirths are < 1000 g, the developing/developed country difference is actually larger than apparent from this study. Maceration was uncommon, which indicates that most of the deaths probably occurred during labor. The low rates of physician attendance, hospital delivery, and cesarean section deliveries suggest that stillbirth rates could be reduced by access to higher quality institutional deliveries.
我们的目标是在一项针对发展中世界社区环境的多地点人群研究中确定死产率。
对5个资源匮乏国家(刚果民主共和国、危地马拉、印度、赞比亚和巴基斯坦)以及1个中等水平国家(阿根廷)在18个月期间所有社区分娩的结果进行前瞻性评估。出生体重>1000克且无生命迹象的婴儿被定义为死产。
纳入了60324例分娩的结果。死产率从巴基斯坦的每1000例34例到阿根廷的每1000例分娩9例不等。死产率的增加与低技能医疗服务提供者、院外分娩以及低剖宫产率显著相关。17.2%的死产存在浸软现象。
这些发展中国家出生体重≥1000克的婴儿的死产率显著高于发达国家报告的死产率(每1000例分娩3 - 5例)。由于大多数发达国家将死产定义为妊娠≥20周或出生体重≥500克,并且几乎所有死产中有一半出生体重<1000克,因此发展中国家与发达国家的差异实际上比本研究显示的更大。浸软现象并不常见,这表明大多数死亡可能发生在分娩期间。医生出诊、住院分娩和剖宫产率较低表明,通过获得更高质量的机构分娩服务,死产率可能会降低。
