New research says 35 percent of child deaths worldwide are caused by hunger. The research comes from poor to middle-income countries in Africa, Asia and Latin America.
Robert Black from the Bloomberg School of Public Health at Johns Hopkins University in Maryland is the lead writer of the research. He says more than 3.5 million mothers and children under five die in poor countries each year because of hunger.
He says about two million children die from underdevelopment, either before or after birth. Millions of others who survive face a lifetime of disabilities or early death and the effects are not just physical. Poor mental development also results from hunger as children grow. Then the
cycle of poverty and hunger often continues for their children.
Doctor Black says hungry children can have conditions like high blood pressure and heart disease as a result of hunger. He says the studies show that food programs need to place the greatest importance on the first two years of life. Hungry children can suffer their whole life damage from age two.
It is high time their diets were improved. Diets should include foods rich in vitamin A and other vitamins and minerals. The researchers say early help such as this could reduce child deaths by 25%.
This research has also faced some criticism. A medical aid group says the researchers underestimate(低估) the number of child deaths due to hunger. The researchers say there are findings that support this treatment but more studies are needed to compare it to hospital care.
