The Human and Economic Cost of Hidden Hunger

Abstract

Background Micronutrient malnutrition is a public health problem in many developing countries. Its negative impact on income growth is recognized in principle, but there are widely varying estimates of the related economic cost. Objective To discuss available studies that quantify the cost of micronutrient malnutrition, and to develop an alternative framework and apply it to India. Methods Detailed burden of disease calculations are used to estimate the economic cost of micronutri- ent malnutrition based on disability-adjusted life years (DALYs) lost. Results The short-term economic cost of micronutri- ent malnutrition in India amounts to 0.8% to 2.5% of the gross domestic product. Conclusions Although the results confirm that micro- nutrient malnutrition is a huge economic problem, the estimates are lower than those of most previous studies. The differences may be due to differences in underlying assumptions, quality of data, and precision of calculation, but also to dynamic interactions between nutrition, health, and economic productivity, which are difficult to capture. Clear explanation of all calculation details would be desirable for future studies in order to increase credibility and transparency.
