"To see adults in this condition, it's a very serious situation," Mieke Steenssens, a volunteer nurse with Doctors Without Borders, said as she registered the 5-foot-4 Usheto's weight at just 73 pounds.
Aid groups say the older victims suggest there is an escalation in the crisis in Ethiopia, a country that drew international attention in 1984 when a famine compounded by communist policies killed 1 million people.
This year's crisis, brought on by a countrywide drought and skyrocketing global food prices, is far less severe. But while figures for how many adults and older children are affected are not available, at least four aid groups said they noticed a troubling increase.
"We're overwhelmed," said Margaret Aguirre, a spokeswoman for the International Medical Corps, an aid agency based in Santa Monica, Calif. "There's not enough food and everyone's starving, and that's all there is to it.
"Older children are starting to show the signs of malnutrition when normally they might be able to withstand shocks to the system," she added. "What's particularly concerning is that the moderately malnourished are soaring. It's increasing so much that it means those children are going to slide into severe malnutrition."
Ethiopia is not alone in suffering through the worldwide food crisis, which is threatening to push the number of hungry people in the world toward 1 billion. Last week, a UN summit of 181 countries pledged to reduce trade barriers and boost agricultural production to combat rising food prices.
But in Ethiopia, food production is hampered by drought, meaning the country has been hit with a double blow. Drought is especially disastrous in Ethiopia because more than 80 percent of people live off the land. Agriculture drives the economy, accounting for half of all domestic production and 85 percent of exports.
Sending more food is one solution, but there already is a global crunch as rising fuel prices drive up the cost of fertilizers, farm vehicle use, and transport of food to market. Biofuels, which are made from crops such as sugar cane and corn, are another contentious issue, with critics saying they compete with food crops.
