早产是全球 5 岁以下儿童死亡的主要原因。尽管高收入国家的早产儿存活率有所提高，但由于许多低收入和中等收入国家缺乏足够的新生儿护理，早产儿仍然会死亡。我们估算了 2014 年全球、区域和国家的早产率，以及一些选定国家随时间变化的趋势。我们在国家民事登记和生命统计（CRVS）数据库中系统地检索了 194 个 WHO 会员国 1990 年至 2014 年的早产数据。我们还检索了没有 CRVS 数据或 CRVS 数据有限的国家的人口代表性调查和研究。对于2014年拥有高质量早产数据的38个国家，直接报告数据。对于 1990 年至 2014 年间至少有三个数据点的国家，我们使用线性混合回归模型来估计早产率。我们还计算了 2014 年区域和全球早产的估计值。我们确定了 107 个国家的 1241 个数据点。据估计，2014 年全球早产率为 10·6%（不确定性区间为 9·0–12·0），相当于 2014 年估计有 14·84 百万（12·65 百万–16·73 百万）活早产。其中 12·70 万（81·1%）早产发生在亚洲和撒哈拉以南非洲。 2014 年各地区早产率从北非的 13·4% (6·3–30·9) 到欧洲的 8·7% (6·3–13·3)。 2014年，印度、中国、尼日利亚、孟加拉国和印度尼西亚占全球1.39亿活产中的57·900万（41×4%），早产占6·600万（44×6%）。在拥有高质量数据的38个国家中，自2000年以来，26个国家的早产率有所上升，12个国家的早产率有所下降。我们估计，2000年全球早产率为9×8%（8×3–10×9），2014年为10×6%（9×0–12×0）。早产仍然是儿童死亡率和提高孕产妇和新生儿护理质量的一个关键问题。为了更好地了解早产的流行病学，需要提高数据的质量和数量，包括定义、测量和报告的标准化。世界卫生组织和一毛钱游行。
Preterm birth is the leading cause of death in children younger than 5 years worldwide. Although preterm survival rates have increased in high-income countries, preterm newborns still die because of a lack of adequate newborn care in many low-income and middle-income countries. We estimated global, regional, and national rates of preterm birth in 2014, with trends over time for some selected countries. We systematically searched for data on preterm birth for 194 WHO Member States from 1990 to 2014 in databases of national civil registration and vital statistics (CRVS). We also searched for population-representative surveys and research studies for countries with no or limited CRVS data. For 38 countries with high-quality data for preterm births in 2014, data are reported directly. For countries with at least three data points between 1990 and 2014, we used a linear mixed regression model to estimate preterm birth rates. We also calculated regional and global estimates of preterm birth for 2014. We identified 1241 data points across 107 countries. The estimated global preterm birth rate for 2014 was 10·6% (uncertainty interval 9·0–12·0), equating to an estimated 14·84 million (12·65 million–16·73 million) live preterm births in 2014. 12· 0 million (81·1%) of these preterm births occurred in Asia and sub-Saharan Africa. Regional preterm birth rates for 2014 ranged from 13·4% (6·3–30·9) in North Africa to 8·7% (6·3–13·3) in Europe. India, China, Nigeria, Bangladesh, and Indonesia accounted for 57·9 million (41×4%) of 139·9 million livebirths and 6·6 million (44×6%) of preterm births globally in 2014. Of the 38 countries with high-quality data, preterm birth rates have increased since 2000 in 26 countries and decreased in 12 countries. Globally, we estimated that the preterm birth rate was 9×8% (8×3–10×9) in 2000, and 10×6% (9×0–12×0) in 2014. Preterm birth remains a crucial issue in child mortality and improving quality of maternal and newborn care. To better understand the epidemiology of preterm birth, the quality and volume of data needs to be improved, including standardisation of definitions, measurement, and reporting.
