ITHACA, N.Y. -- Almost 40 percent, or about 184 million, of the developing world's children under age 5 outside of China have stunted growth due to inadequate nutrition, reports a Cornell University nutritionist and statistician.
Although the worldwide prevalence of stunting is declining by about 0.5 of a percentage point each year, more than half the children in some regions of the developing world, such as Southeast Asia, are severely below the normal height for their age, says Edward Frongillo, associate professor of nutritional sciences at Cornell.
"These figures are just the tip of the iceberg. They indicate that the whole population in certain regions is not growing as well as it should be," says Frongillo, who has been researching child growth and stunting for more than 20 years.
He reported his findings to the Federation of American Societies for Experimental Biology (FASEB) in San Francisco in April in a symposium he organized on why and how stunting occurs, and in the The Third Report on the World Nutrition Situation, published by the United Nations in December 1997. The UN report used data from the World Health Organization global database on child growth and malnutrition. This is the first time that information on global and regional trends in stunting has been available.
Child growth is considered a good indicator of overall socioeconomic development and human welfare in developing countries, says Frongillo. Stunting is a physical indicator of a broad spectrum of nutritional deficiencies and is often linked to poor mental development. Stunting is a cumulative process of poor growth that primarily occurs before the age of 3 years and is not easily reversed.
"It is very disturbing that in most of the developing world, a large proportion of children are suffering from malnutrition severe enough that they are not achieving near their developmental potential," Frongillo adds.
