Overall, it is estimated that 15%
to 20% of all births worldwide are low birth weight,
representing more than 20 million births a year. The goal
is to achieve a 30% reduction in the number of infants
born with a weight lower than 2500 g by the year 2025
(1). This would translate into a 3% relative reduction
per year between 2012 and 2025 and a reduction from
approximately 20 million to about 14 million infants
with low weight at birth.
