Malnourished Children Prone to Diabetes, Heart Disease as Adults: Study

Recent study conducted by scientists in baboons sheds light on why people who are malnourished in early childhood often experience poor health as adults.

The study found that baboons born in times of famine are more vulnerable to food shortages later in life.

Most of the Elderly Patients in Emergency Department are Malnourished
Among the emergency department patients age 65 and older, more than half of those seen in UNC Hospitals during an 8-week period were either malnourished or at risk for malnutrition.

After the plains of southern Kenya experienced a severe drought in 2009 that took a terrible toll on wildlife, researchers at the Duke and the Princeton Universities looked at how 50 wild baboons coped with the drought, and whether the conditions they faced in infancy played a role.

"The data suggest that early adversity carries lifelong costs," said study author Jenny Tung from Duke University.

During the drought, the grasslands the animals depend on for food dried up and watering holes disappeared, leaving many animals starving or weak from hunger.

Nutrition Therapy may Not Lead to Long-Term Benefits for Malnourished Children
Researchers suggest that while nutrition therapy can save the lives of millions of malnourished infants, it may not be able to restore the imbalance.

"We lost 98 percent of the wildebeest population, 75 percent of the zebra population and 30 percent of the elephant population," said study co-author Susan Alberts from Duke University.

Most baboons made it, but the drought left them underweight and many females stopped ovulating.

In the study scheduled to appear in American Naturalist, the researchers compared two groups of females - one group born during low rainfall years and the other born during normal rainfall years.

During the 2009 drought, baboons born during low rainfall years were 60 percent less likely to become pregnant, whereas pregnancy rates dipped by only 10 percent for females born during normal rainfall years.

In Sunderbans A Third of All Kids Malnourished
The Sunderbans, the world's largest mangrove forests, has seen rampant malnutrition among children.

Drought babies born to higher-status mothers were less affected by the 2009 event.

The findings help explain why people who are malnourished in early childhood go on to have higher rates of obesity, diabetes and heart disease as adults.

"It’s bad to be born in bad times, but with the right social or economic environment, that can be mitigated," Alberts added.
