To determine population-based neonatal mortality rates in low- and middle-income countries and to examine gestational age, birth weight, and timing of death to assess the potentially preventable neonatal deaths.
A prospective observational study was conducted in communities in five low-income countries (Kenya, Zambia, Guatemala, India, and Pakistan) and one middle-income country (Argentina). Over a 2-year period, all pregnant women in the study communities were enrolled by trained study staff and their infants followed to 28 days of age.
Between October 2009 and March 2011, 153,728 babies were delivered and followed through day 28. Neonatal death rates ranged from 41 per 1000 births in Pakistan to 8 per 1000 in Argentina; 54% of the neonatal deaths were >37 weeks and 46% weighed 2500 g or more. Half the deaths occurred within 24 hours of delivery.
In our population-based low- and middle-income country registries, the majority of neonatal deaths occurred in babies >37 weeks' gestation and almost half weighed at least 2500 g. Most deaths occurred shortly after birth. With access to better medical care and hospitalization, especially in the intrapartum and early neonatal period, many of these neonatal deaths might be prevented.
确定中低收入国家的人群新生儿死亡率,并检查胎龄、出生体重和死亡时间,以评估潜在可预防的新生儿死亡。
在五个低收入国家(肯尼亚、赞比亚、危地马拉、印度和巴基斯坦)和一个中等收入国家(阿根廷)的社区中进行了一项前瞻性观察研究。在两年期间,由经过培训的研究人员招募研究社区中的所有孕妇,并对其婴儿进行随访至 28 天。
2009 年 10 月至 2011 年 3 月期间,共有 153728 名婴儿分娩并随访至第 28 天。新生儿死亡率范围从巴基斯坦的每 1000 例活产 41 例到阿根廷的每 1000 例活产 8 例;54%的新生儿死亡发生在 37 周以上,46%的新生儿体重为 2500 克或以上。一半的死亡发生在分娩后 24 小时内。
在我们基于人群的中低收入国家登记处,大多数新生儿死亡发生在胎龄大于 37 周的婴儿中,几乎一半的婴儿体重至少为 2500 克。大多数死亡发生在出生后不久。如果能够获得更好的医疗保健和住院治疗,特别是在分娩期间和新生儿早期,许多这些新生儿死亡可能是可以预防的。
