Insufficient progress has been made in most developing countries to meet the United Nations' target of halving the proportion of children who suffer from hunger by 2015 compared with 1990 levels, according to a systematic analysis of data on children's height and weight, published today in the Lancet. Although the nutritional status of children under five has improved overall since 1985, one in five infants and children in developing countries is still moderately or severely underweight, amounting to an estimated 110 million children worldwide. Another 148 million are mildly underweight.
The UN set the target as part of its Millennium Development Goals. This new analysis, led by Professor Majid Ezzati from the School of Public Health at Imperial College London, estimates that while 61 out of the 141 developing countries studied are likely to meet this target, the developing world as a whole has less than a 5% chance of succeeding. Progress has been uneven between regions, with Asia and Latin America making the strongest improvements and sub-Saharan Africa falling behind.
Because nutrition has a strong effect on children's growth, nutritional status in children can be assessed using scores based on their height and weight relative to their age, called height-for-age and weight-for-age Z scores (HAZ and WAZ).
Researchers from Imperial College London, the World Health Organisation and universities in the US compiled HAZ and WAZ data from national surveys and other sources, and used statistical methods to estimate average Z scores and the prevalence of undernutrition (defined as insufficient food intake and absorption) for entire countries.
The results show that:
