CHILDREN born in developing countries this year will lose more than $177 billion in potential life-time earnings because of stunting and other delays in physical development, scientists said last
Children who have poor growth in their first years of life tend to perform worse at school, which usually leads to poorer earning power later on. The Harvard scientists calculated that every dollar invested in eliminating poor early growth would yield a $3 return.
“$177 billion is a big pay cheque that the world is missing out on – about half a percentage point of GDP of these countries,” said Peter Singer, head of Grand Challenges Canada, which funded the research through its Saving Brains programme.
“We have to stop wasting the world’s most precious economic and social asset and ensure children thrive.”
Poor nutrition, premature birth, low breastfeeding rates and early exposure to infection are among several causes of stunting that affects three in 10 children in the developing world.
World Bank president Jim Yong Kim recently warned that childhood stunting was “a great unrecognised disaster”, adding that countries that failed to invest in early child development would be left behind in an increasingly complex, digital world.
Echoing his remarks, Singer said the economic value of investing in children’s early years was “absolutely humongous”.
The Harvard scientists arrived at the $177 billion figure after looking at indicators for the 123 million children born in 2010 in 137 low and middleincome countries.
The estimated reduction in earnings due to poor early growth was largest in south Asia where children born in any given year can expect to lose $46.6 billion in potential earnings over their lifetimes, followed by Latin America ($44.7 billion) and sub-Saharan Africa ($34.2 billion).
Countries with the most to gain in terms of future incomes were India ($37.9 billion), Mexico ($18.5 billion) and China ($13.3 billion).
