1 in 10 babies worldwide are born early

An estimated 13.4 million babies were born early (before 37 full weeks of pregnancy) in 2020 – which is around 1 in 10 of all live births – according to a detailed study published in the Lancet by authors from the World Health Organization (WHO), the United Nations Children’s Fund (UNICEF) and the London School of Hygiene and Tropical Medicine.

Since prematurity is the leading cause of death in children’s early years, there is an urgent need to strengthen both care for preterm babies as well as prevention efforts – particularly maternal health and nutrition – so as to improve childhood survival. For those who live, preterm birth also significantly increases the likelihood of suffering major illnesses, disability and developmental delays, and even chronic diseases as adults like diabetes and heart conditions.

As with other major trends relating to maternal health, no region of the world has significantly reduced rates of preterm births over the last decade. The annual global rate of reduction in preterm births between 2010 and 2020 was just 0.14%.

“Preterm babies are especially vulnerable to life-threatening health complications and they need special care and attention,” said Dr Anshu Banerjee, Director of Maternal, Newborn, Child and Adolescent Health and Ageing at WHO: “These numbers show an urgent need for serious investment in services available to support them and their families as well as a greater focus on prevention – in particular, ensuring access to quality health care before and during every pregnancy. »

The paper, National, regional, and global estimates of preterm birth in 2020, with trends from 2010: a systematic analysis, provides global, regional and country estimates and trends for preterm births between 2010 and 2020, revealing large disparities between regions and countries. Around 65% of preterm births in 2020 occurred in sub-Saharan Africa and southern Asia, where over 13% babies were born preterm. The rates in the worse affected countries – Bangladesh (16.2%), Malawi (14.5%) and Pakistan (14.3%) – are three or four times higher than those in the least affected countries – Serbia (3.8%), Moldova (4%) and Kazakhstan (4.7%).

Preterm birth is not just an issue in low and middle-income countries, however, and the data shows clearly that it affects families in all parts of the world. Rates of 10% or higher occur in some high-income countries such as Greece (11.6%) and the United States of America (10%).

Maternal health risks, such as adolescent pregnancy, infections, poor nutrition, and pre-eclampsia, are closely linked to preterm births. Quality antenatal care is critical to detect and manage complications, to ensure accurate pregnancy dating through early ultrasound scans and if needed, to delay labour through approved treatments.
