In this Series paper, we review trends since the 2005 Lancet Series on Neonatal Survival to inform acceleration of progress for newborn health post-2015. On the basis of multicountry analyses and multi-stakeholder consultations, we propose national targets for 2035 of no more than 10 stillbirths per 1000 total births, and no more than 10 neonatal deaths per 1000 livebirths, compatible with the under-5 mortality targets of no more than 20 per 1000 livebirths. We also give targets for 2030. Reduction of neonatal mortality has been slower than that for maternal and child (1-59 months) mortality, slowest in the highest burden countries, especially in Africa, and reduction is even slower for stillbirth rates. Birth is the time of highest risk, when more than 40% of maternal deaths (total about 290,000) and stillbirths or neonatal deaths (5·5 million) occur every year. These deaths happen rapidly, needing a rapid response by health-care workers. The 2·9 million annual neonatal deaths worldwide are attributable to three main causes: infections (0·6 million), intrapartum conditions (0·7 million), and preterm birth complications (1·0 million). Boys have a higher biological risk of neonatal death, but girls often have a higher social risk. Small size at birth--due to preterm birth or small-for-gestational-age (SGA), or both--is the biggest risk factor for more than 80% of neonatal deaths and increases risk of post-neonatal mortality, growth failure, and adult-onset non-communicable diseases. South Asia has the highest SGA rates and sub-Saharan Africa has the highest preterm birth rates. Babies who are term SGA low birthweight (10·4 million in these regions) are at risk of stunting and adult-onset metabolic conditions. 15 million preterm births, especially of those younger than 32 weeks' gestation, are at the highest risk of neonatal death, with ongoing post-neonatal mortality risk, and important risk of long-term neurodevelopmental impairment, stunting, and non-communicable conditions. 4 million neonates annually have other life-threatening or disabling conditions including intrapartum-related brain injury, severe bacterial infections, or pathological jaundice. Half of the world's newborn babies do not get a birth certificate, and most neonatal deaths and almost all stillbirths have no death certificate. To count deaths is crucial to change them. Failure to improve birth outcomes by 2035 will result in an estimated 116 million deaths, 99 million survivors with disability or lost development potential, and millions of adults at increased risk of non-communicable diseases after low birthweight. In the post-2015 era, improvements in child survival, development, and human capital depend on ensuring a healthy start for every newborn baby--the citizens and workforce of the future.
在本系列论文中,我们回顾了自 2005 年《柳叶刀》新生儿生存系列报告以来的趋势,以期为 2015 年后新生儿健康的加速发展提供信息。基于多国分析和多方利益攸关方协商,我们提出了 2035 年的国家目标,即每 1000 例总分娩中死产不超过 10 例,每 1000 例活产中新生儿死亡不超过 10 例,这与每 1000 例活产中 5 岁以下儿童死亡率不超过 20 例的目标一致。我们还给出了 2030 年的目标。新生儿死亡率的下降速度慢于母婴(1-59 个月)死亡率,在负担最重的国家最慢,特别是在非洲,死产率的下降速度甚至更慢。分娩时的风险最高,每年有超过 40%的孕产妇死亡(总计约 29 万)和死产或新生儿死亡(550 万)发生。这些死亡发生得很快,需要医护人员迅速做出反应。全世界每年有 290 万新生儿死亡,主要归因于三个原因:感染(60 万)、分娩期间状况(70 万)和早产并发症(100 万)。男孩的新生儿死亡生物学风险较高,但女孩的社会风险往往较高。出生体重较小--由于早产或小于胎龄(SGA),或两者兼而有之--是超过 80%的新生儿死亡的最大风险因素,并增加了新生儿后死亡率、生长发育不良和成年后非传染性疾病的风险。南亚的 SGA 发生率最高,撒哈拉以南非洲的早产率最高。这些地区的足月 SGA 低出生体重儿(1040 万)有发育迟缓及成年后代谢疾病的风险。1500 万例早产,特别是妊娠 32 周以下的早产,面临着最高的新生儿死亡风险,以及持续的新生儿后死亡率风险和重要的长期神经发育损伤、发育迟缓及非传染性疾病风险。每年有 400 万新生儿患有其他危及生命或致残的疾病,包括分娩期间相关脑损伤、严重细菌感染或病理性黄疸。全世界一半的新生儿没有出生证明,几乎所有的死产和死产都没有死亡证明。要计算死亡人数,必须改变这种情况。如果到 2035 年仍不能改善出生结局,预计将有 1.16 亿人死亡,9900 万人有残疾或丧失发展潜力,数百万人因出生体重低而面临非传染性疾病风险增加。在后 2015 年时代,儿童生存、发展和人力资本的改善取决于确保每个新生儿都有一个健康的开端--这是未来的公民和劳动力。
