If existing maternal and child nutrition interventions were implemented in poor countries, cases of stunting among under 3s could be reduced by a third, and deaths by up to a quarter, according to new research being published today.
Professor Simon Cousens, of the London School of Hygiene & Tropical Medicine, is one of the authors of a paper which appears as part of the Lancet Maternal and Child Undernutrition Series, which is being launched this week. Professor Cousens, along with four other series authors, is presenting his findings at a press event at the Science Media Centre.
178 million children under five are stunted, and most of these live in Sub-Saharan Africa and south-central Asia. 160 million stunted children (90%) live in just 36 countries, and make up 46% of the 348 million children in those countries. In addition, 19 million children are affected by severe acute malnutrition.
Historical evidence of improvements in nutrition in developed countries has shown that stature, living standards, reduced disease exposure and education are linked, and that almost all stunting is avoidable. Stunting is difficult to reverse after the age of three, so it is important to focus on interventions in pregnancy and in young children, especially those aged under two. In the past most nutrition programme reports and assessments have focused on weight gain rather than linear growth, and linear-growth retardation has been viewed as difficult to change. However, in the short term, about one third of stunting could be averted with existing interventions, say the authors. These include strategies to promote improved complementary feeding, micronutrient interventions, and interventions aimed at reducing the burden of disease.
