The Magic Number Is ...

1 Longevity Tied to Sleep Duration

The secret to long life may be the amount of sleep you get, finds research begun 14 years ago. Scientists from UC San Diego revisited studies conducted between 1995 and 1999 that monitored 459 women to determine their sleep habits and whether they affected mortality. The women wore wrist monitors to record sleep durations and, at the time, scientists posited that sleeping for 6.5 to 7.5 hours was best for longevity. Fourteen years later, 444 of the participants were still alive and, according to Dr. Daniel F. Kripke, lead researcher, “the best survival was observed among women who slept 5 to 6.5 hours. This means that women who sleep as little as five to six-and-a-half hours have nothing to worry about since that amount of sleep is evidently consistent with excellent survival.”

Lowers Risk Significantly

2 CV Disease Risk Down in Women Who Visit Dentist

Women who see their dentist regularly have a significantly lower risk for heart attack, stroke and other cardiovascular problems, finds a new study from UC Berkeley that indicates the risk is reduced by as much as 30 percent. The study of 7000 people, ages 44 to 88, did not find a similar benefit for men. "We think the findings reflect differences in how men and women develop cardiovascular disease," said study co-author Dr. Stephen Brown. "Other studies suggest that estrogen has a protective effect against heart disease because it helps prevent the development of atherosclerosis. It's not until women hit menopause around age 50 to 55 that they start catching up with men." The study considered risk factors such as tobacco and alcohol use and high blood pressure, among others.

Making Them Non-Addictive

3 Experts Urge Reduction of Nicotine in Cigarettes

Tobacco research experts called for an urgent reduction of nicotine in cigarettes to non-addictive levels saying this will have a major impact on public health. Lowering nicotine levels in cigarettes will reduce the number of smoking-related annual deaths, decrease adolescent experimentation with cigarettes and reduce overall dependence on tobacco among currently addicted smokers. At present, about 20 percent of US adults, or 44 million people smoke cigarettes. The study’s authors say this number can be reduced to about 5 percent by cutting nicotine levels. Saying that “nicotine addiction sustains tobacco use,” researchers cite current studies that say a reduction in cigarettes’ nicotine levels does not lead to smoking more cigarettes but decreases smoking overall.

Despite Education Awareness

4 Americans Don’t Eat Enough Vegetables

Despite two decades of education awareness about the importance of eating a balanced diet that includes vegetables, Americans pass up greens in favor of less healthy foods, finds the Centers for Disease Control and Prevention’s nationwide behavioral study which says that only 26 percent of US adults eat vegetables three or more times a day. Americans eat less than half of what the guidelines set up by the federal government more than a decade ago recommend. Here, some of the more salient points of the study: The number of dinners prepared at home that included a salad was 17%, down from 22% in 1994; salad was ordered as a main course at restaurants about 5% of the time; only 23% of meals served in US households included a vegetable. And, sadly for some, French fries don't count.

Guilty of Intentional Syphilis

5 U.S. Apologies for Sex Studies Done 64 Years Ago

The U.S. has apologized to Guatemala for unethical medical studies completed in 1946 to 1948, reports CNN. For the research on the effectiveness of penicillin for treatment or prevention of syphilis, doctors intentionally infected mental patients, commercial sex workers, prisoners and soldiers with sexually transmitted diseases. The study, called Public Health Service Sexually Transmitted Disease Inoculation Study, involved unknowing research participants in Guatemala. The shameful research was revealed recently when Wellesley College researcher Susan Reverby found archivied notes from the project. According to the research notes, more than 696 people were infected with syphilis, 772 with gonorrhea and 142 with chancres.

Medication May Be the Link

6 Kidney Disease Linked to Hearing Loss in New Study

A study involving adults 50 years and older suggests that those with moderate kidney disease should have their hearing tested. Fifty-four percent of the adults with moderate kidney diseases had hearing loss to some degree, while 30 percent had severe hearing loss. According to the National Institute on Deafness and Other Communication Disorders, only 18 percent of adults aged 45 to 64 in the general population suffer from hearing loss. Previous studies have linked both conditions in some rare syndromes, but this study suggests hearing loss can be linked to any older adult with kidney disease. The results do not suggest a cause and effect relationship between the two conditions and it was noted that some of the medications used to treat kidney disease can have an effect on hearing.
