19 million babies at risk

NEARLY 19 million babies born globally every year — 14 per cent — are at risk of permanent yet preventable brain damage and reduced cognitive function because a lack of iodine in the earliest years of life, according to a new joint report by UNICEF and GAIN released early this month. More than one in four of these children — 4.3 million — live in South Asia.
Brighter futures: Protecting early brain development through salt iodisation notes that iodine deficiency is a leading cause of preventable brain damage worldwide. Insufficient iodine during pregnancy and infancy results in neurological and psychological deficits, reducing a child’s IQ by eight to 10 points. This translates into major losses in the cognitive capital of entire nations and thus their socioeconomic development.
“The nutrients a child receives in the earliest years of life influence their brain development for life, and can make or break their chance of a prosperous future,” said UNICEF senior nutrition adviser Roland Kupka. “By protecting and supporting children’s development in early life, we are able to achieve immense results for children throughout their lifespan.”
Salt iodisation is both cost-effective and economically beneficial at only $US0.02-0.05 ($F0.04-0.10) per child annually. Every dollar spent on salt iodisation is estimated to return $US30 ($F60) through increased future cognitive ability.
“We acknowledge the work countries in the Pacific have done on legislating for iodised salt, which is vital to ensure that babies receive the correct nutrients for brain development in the early years of life,” said UNICEF Pacific representative Sheldon Yett.
“However, it’s important that governments take actions to strengthen their regulation systems, especially as there is such a close link with brain development in early childhood based on iodine consumption,” he said.
While South Asia is home to the largest proportion of babies at risk globally, the region has the second highest iodised salt coverage rate at 87 per cent of the population, preceded by East Asia and the Pacific at 91 per cent coverage. The lowest coverage with iodised salt was seen in Eastern and Southern Africa, where around 25 per cent of the population do not have access to iodised salt, leaving 3.9 million babies every year unprotected against iodine deficiency disorders.
“Iodine is critical for childhood development,” said Greg S Garrett director of food policy at GAIN. “Due to the collective efforts of governments, industry, civil society, UNICEF, GAIN and others, we are on the verge of being able to ensure sustainable iodine intakes for all children. But there is still much more to be done to end iodine deficiency and we hope others join our efforts to further scale up salt iodisation in the hardest to reach areas.”
The earliest moments of life, from conception up to age two, are the most critical for a child’s development. Nutrition — along with protection and stimulating activities like play and early learning — during a child’s first 1000 days shape brain development for life.
The report outlines urgent steps to reduce the risk of mental impairment to babies’ growing brains:
p Integrate salt iodisation into national plans to support children’s nutrition and brain development in early childhood;
p Align salt iodisation and salt reduction agendas;
p Establish surveillance systems to identify unreached populations;
p Strengthen regulatory systems to enforce existing legislation on salt iodisation; and
p Recognise the growing importance of fortified foods as potential sources of iodised salt.
UNICEF and GAIN have been working together for the past 10 years to tackle iodine deficiency disorders:
o In Europe and Central Asia, the salt industry has made iodisation part of good manufacturing practices;
o In East Asia and the Pacific, strong policies and legislation helped establish iodised salt as the norm for households and industry;
o In Eastern and Southern Africa, regional commissions have championed salt iodisation in the context of a broader nutrition agenda;
o In South Asia, salt iodisation has successfully improved population iodine status and a major focus is now to achieve universal coverage and achieve program sustainability;
o In West and Central Africa, changing trade patterns have affected the salt industry, but there has been remarkable co-operation in harmonising standards, including those for iodised salt.
