Global preterm birth rates reached 11.1 percent of all livebirths in 2010
In short: Researchers conducting a systematic analysis of 184 countries found that approximately 14.9 million babies were born preterm in 2010. This accounted for 11.1% of all livebirths worldwide, with rates varying significantly by region, from roughly 5% in several European nations to 18% in some African countries.
This study provides a comprehensive global overview of preterm birth trends, highlighting that over 60% of these births occurred in South Asia and sub-Saharan Africa. By analyzing national registries, surveys, and various studies, the researchers established a baseline for understanding this major cause of child mortality.
The researchers used multilevel statistical models and loess regression to estimate rates, though the findings are limited by the fact that preterm birth data are not routinely collected by UN agencies.
Why it matters: Preterm birth is a substantial global health burden that is increasing in regions with reliable data.
