The Safe Childbirth Checklist aims to make childbirth safer for women and babies around the word by encouraging the use of essential, lifesaving childbirth practices at the health-care facility level.


Improving outcomes for infants around the world requires solutions to address gaps across the entire ecosystem of care. The BetterBirth Program is working to build the evidence base for solutions to help all infants survive and thrive.

Low Birthweight Infant Feeding Exploration (LIFE)

Launched in 2019, Ariadne Labs’ Low Birthweight Infant Feeding Exploration (LIFE) study documents current feeding practices, growth patterns, child development, and other health outcomes among more than 1,100 low birthweight infants in low- and middle-income countries. The study aims to identify which infants are at highest risk, determine effective interventions,  highlight remaining evidence gaps for future research, and contribute to global guidelines with evidence-based action steps.

Globally, 20.5 million infants are born with low birthweight each year. These infants account for more than 80% of newborn deaths, with 1.9 million dying annually, and are 20 times more likely to die than normal birthweight infants. They are also at increased risk for illness, growth deficits, and developmental delays. Low- and middle-income countries bear the greatest burden of low birthweight births and neonatal deaths.

In recent years, there has been an increased global focus on low birthweight infants. In 2015, the United Nations identified ending preventable deaths of newborns and children by 2030 as a Sustainable Development Goal, and in 2020, the WHO published standards for improving the quality of care for small and sick newborns in health facilities. 

To make progress toward these goals, researchers, policymakers, clinicians, and funders need an enhanced evidence base to strengthen existing global feeding guidelines and identify priority areas for further research. The LIFE study is filling this evidence gap to help ensure that low birthweight infants have the chance to survive and thrive.

A recently published Executive Summary details study findings for infants from birth to one year. The summary outlines key actions for an evidence-based approach to improve growth, survival, and development outcomes for these infants, with a focus on early identification of the highest risk infants to allow for early intervention.

Key Findings

  • Specific characteristics make some infants more vulnerable than others to illness, slow growth, and death. These outcomes can be avoided with focused interventions at key timepoints.
  • Growth monitoring soon after birth allows for early identification of risk and proactive intervention to prevent poor growth and developmental outcomes in later infancy.
  • Assessment tools designed specifically for low birthweight infants in resource limited settings are needed to facilitate clinical decision-making and allocation of scarce resources.
