Such investments - greatest during periods of GDP growth in many countries - had an ‘indirect impact’ in reducing malnutrition.
Dr Bárbara Soriano and Dr Alberto Garrido from the Technical University of Madrid in Spain used data from data from 1991–2012 to determine whether higher economic growth accelerated reductions in undernutrition in 27 low-income and middle-income countries. Four geographical regions were selected — South Asia (4 countries), East Asia (5), Latin America (11) and sub-Saharan Africa (7).
Improved access to drinking water had the greatest malnutrition impact, more than literacy and public health improvements, but change came at differing rates even when GDP improvement was similar among nations.
“These results conclude that around two years of annual revenue growth are necessary to achieve improvements in undernourishment,” the paper noted. “Over time economic growth’s impact on reducing undernourishment is higher, thus three to eight years growth is optimal when compared to the impact of economic growth in the short term.”
The researchers were quick to point out that the study omitted many direct interventions that have proved essential for reducing undernourishment, such as micronutrient supplementation, food fortification or diet supplementation for pregnant women.
Economy and undernutrition
Little research has been carried out in regards to links between economic growth and undernutrition reduction.
One study found that a number of developing countries experiencing economic growth have seen their nutritional status deteriorate.
One analysis of the impact of national income on child malnutrition found that growth and specific nutrition programs were paramount in halving the levels of child malnutrition.
A similar study looking at nutrient demand functions suggested income was overrated as a determinant of adequate nutrition.
