Diabetes in Children Is Linked to Later Ills

Children who get Type 2 diabetes face a much higher risk of kidney failure and death by middle age than people who develop diabetes as adults, a study suggests.

The study offers strong evidence of the consequences of the nation's growing epidemic of obesity-related diabetes in children, said co-author William C. Knowler of the National Institute of Diabetes and Digestive and Kidney Diseases.

The study, in today's Journal of the American Medical Association, involved Pima Indians in Arizona, who have high rates of diabetes and obesity.

Of the 1,865 participants with Type 2 diabetes, 96 developed it in childhood. The researchers calculated that the incidence of end-stage kidney failure and death by age 55 was nearly five times as high in those who developed Type 2 diabetes before age 20 as in those who developed diabetes in adulthood.

Riskier Lifestyles Cited In Young Men's Deaths

Young men all over the world have higher death rates than women because of their riskier lifestyles, researchers said yesterday.

Accidents and suicide are the leading killers in men 15 to 34 years old; deaths from heart disease, cancer and chronic liver disease rise sharply in those 35 to 44.

"In every country there is an excess of male deaths due to potentially avoidable reasons. The main causes of death are those that are more or less directly attributable to lifestyle and risk-taking," said Alan White of Leeds Metropolitan University in England.

In a study published in the Journal of Men's Health and Gender, White and his colleague Mike Holmes analyzed the causes of death in men and women ages 15 to 44 in 44 countries.

Monkey Study Offers Insight Into Language

A study has found that language centers in the brains of rhesus macaques light up when the monkeys hear calls and screams from other monkeys, suggesting language skills evolved early in primates.

Researchers who scanned the brains of monkeys while playing them various sounds found the animals used the same areas of the brain when they heard monkey calls as humans do when listening to speech.

Writing in this week's issue of the journal Nature Neuroscience, the researchers said this finding suggests that early ancestors of humans possessed the brain structures needed for language before they developed language itself.

Allen R. Braun of the National Institute on Deafness and Other Communication Disorders and colleagues trained rhesus monkeys to sit quietly in PET scanners used to see which parts of the brain are active. They played coos and screams made by monkeys that the test animals did not know, as well as "nonbiological sounds" such as music and computer-generated noises.
