An estimated 350 million people worldwide have diabetes, according to new research published in the Lancet. It describes the disease as a “rising global hazard” and says global diabetes rates have doubled from 1980 to 2008.
The study attributes 70% of the increase to population growth and aging – the risk of diabetes increases with age. But 30% of the additional cases were caused by other risk factors such as increases in obesity, according to the report.
There's new research to challenge the idea that a young convicted criminal can't change his or her behavior. A study in Proceedings of the National Academy of Sciences suggests that the brains of juvenile offenders aren't necessarily maturing abnormally; rather, they are delayed in their typical development.
"It raises very important questions about our treatment of juvenile offenders," said Benjamin Shannon, of the Department of Radiology at Washington University, St. Louis, and lead author of the study. "We need to have a discussion about the idea that these people deserve very harsh prison treatment, that someone at the age of 14 can be ruined for life."
Of women age 65 and older who undergo a mastectomy to treat advanced breast cancer, nearly half may not be receiving the optimal treatment, a new study finds. The oversight puts these women at greater risk of having the cancer return and increases their risk of dying from the disease.
If you haven't been tested for HIV, today's a good opportunity.
Today, June 27, is National HIV Testing Day, which was created by the The National Association of People with AIDS. You can find a testing site near you through the CDC's website hivtest.org.
Many organizations and communities have organized events around the Testing Day. In Houston, Texas, for instance, there's Hip Hop for HIV Awareness - you get a free ticket to a hip hop concert on July 31 when you get tested.
People unaware of their status transmit the majority of new HIV infections, the CDC says. And nearly 17,000 people with AIDS still die every year in the United States.

I'm a boy and I'm 14 years old. I'm also exactly 5 feet tall. What is wrong with me?
Since January, we've been tracking the training of Dr. Sanjay Gupta and six iReporters as they prep for the August 7 Nautica New York City Triathlon. Starting today, we're adding expert advice from our friends at Triathlete.com
Most triathletes take their training seriously. They are highly motivated, disciplined and willing to work hard to improve.
However, I also see most triathletes making the same training mistakes over and over again. I’m not talking about small mistakes in the details of training, but fundamental ones that impede progress in a major way. I’d like to talk about five such mistakes and show you how to avoid each of them.
Watching violence on television or TV before bedtime can lead to sleep problems for preschoolers, according to a new study in the journal Pediatrics. Experts have known for some time that too much TV time can negatively impact our sleep, but this new research finds that what young children watch and when they watch it can make a difference as well.
The study looked at the television viewing habits and sleep problems of more than 600 preschoolers in Seattle, Washington. When children watched age appropriate TV in the morning or afternoon, they didn't have problems with their sleep, but when the shows contained violence, young people were more likely to experience nightmares and walk up feeling tired.
Obesity experts have been saying for years that children who sit in front of the TV screen day in and day out tend to be heavier. It's the sedentary lifestyle. But now experts are finding it's not only the couch potato effect, but the television ads children are watching, along with other factors that can add inches to their waistlines.
According to a new policy statement from the American Academy of Pediatrics, titled, “Children, Adolescents, Obesity and the Media," junk food and fast food ads increase a child's desire to eat those types of foods. Studies also show that snacking while watching the tube increases. And if kids stay up late at night while watching the tube or playing video games, their lack of sleep can be a major factor in raising their risk for obesity.
“We’ve created a perfect storm for childhood obesity – media, advertising, and inactivity,” said the statement’s lead author, Dr.Victor Strasburger, a member of the AAP Council on Communications and Media. “American society couldn’t do a worse job at the moment of keeping children fit and healthy – too much TV, too many food ads, not enough exercise, and not enough sleep.”
