Hi, I'm Dr. Cindy Haines of HealthDay TV... making news this week ... vitamin D and memory and suppressed anger and heart attacks and MP3 players and hearing damage. First up: Researchers have found that most older people in the United States may be deficient in vitamin D. A recent study in the Archives of Internal Medicine finds that this might hamper their brain function. Researchers included more than 800 adults ages 65 or older, who provided blood samples for vitamin D testing and took mental tests periodically over six years. People who were severely deficient in vitamin D were 60 percent more likely to have substantial declines on one of the tests. Moving on: Patients with heart disease may want to take a look at how they deal with anger. In a recent study from the American Journal of Cardiology, researchers included 644 people with coronary artery disease who answered questions about their anger and their personality. In the following years, people who suppressed their anger were more likely to have a heart attack or die of a heart-related cause. The researchers suggest that people with heart disease who have a lot of suppressed anger may want to learn new ways to handle their anger. And finally: A lot of people are listening to portable MP3 players these days - and they could be putting their hearing at risk. In a recent study from Belgium, 21 volunteers listened to six hour-long music sessions using an MP3 player. Afterward, the participants had temporary changes in hearing sensitivity. According to the researchers, these findings suggest that the devices may be harmful to hearing. Experts say that if other people can hear your music while you're wearing headphones or earbuds, it's most likely too loud. I'm Dr. Cindy Haines of HealthDay TV, with the news that doctors are reading; health news that matters to you.
