Recession Scared Teens Too

1 Teen Birth Rate for 2009 Lowest Ever

The number of teens giving birth fell to an all-time low in 2009 at 39 births per 1,000 teenage girls 15 through 19 years old. According to the government report released today, the teen birth rate for 2009 dropped 6 percent from 2008, making it the lowest rate since officials starting keeping track in 1940. According to MSNBC, surprised experts believe that the low birth rate is due to the economy. Experts believe that the recession, which lasted from December 2007 to June 2009, may have affected decisions of would-be teen mothers. Also, the birth rates for all women have dropped, except for women age 40 and older. The total number of babies born in 2009 is 4.1 million, a nearly 3 percent drop from 2008.

Late Bloomer

2 Ability to Recognize Faces Peaks at 30

When it comes to recognizing and remembering faces, people are at their best around ages 30 to 34, report researchers from Harvard University and Dartmouth College. The research, published in Cognition, is surprising given that most of our other mental abilities peak a decade earlier. For the study, researchers used the Cambridge Face Memory Test to examine facial recognition abilities of 44,000 volunteers ages 10 to 70. Researcher Laura T. Germine of Harvard says that the late-blooming nature of our facial recognition abilities may occur because we simply just get better with practice. "It may be that the parts of the brain we use to recognize faces require this extended period of tuning in early adulthood to help us learn and remember a wide variety of different faces," Germine notes.

3 Dead Butt Syndrome: Runners Be Careful

“Dead butt syndrome,” or gluteus medius tendinosis, occurs when tendons in one of three large butt muscles (gluteus medius) become inflamed. New York Times reports on the story of Jen Miller, a runner diagnosed with dead butt syndrome by her sports medicine doctor. Miller, who had been running for five years, had to stop marathon training because of stabbing pains in her hip. She had been so busy running that she didn't keep up with cross-training and strength training, and that was bad for her gluteus medius! Dr. Darrin Bright, a sports medicine physician, told New York Times that “In the last five to 10 years, we’ve just realized how much of an important role the gluteus medius plays in stabilizing the hips and the pelvis in running.”

4 Spirulina Supplements May Delay ALS Symptoms

Spirulina, a blue-green algae used as an ancient food source by the Aztecs, may have antioxidant and anti-inflammatory effects that could delay the onset of motor symptoms and disease progression in amyotrophic lateral sclerosis (ALS) or Lou Gehrig’s disease. University of South Florida researchers tested compounds from spirulina in pre-symptomatic mice that were bred to have ALS and found that the supplements over a 10-week period reduced inflammatory markers and motor neuron death. “Evidence for oxidative stress has been associated with ALS,” said study lead author Svitlana Garbuzova-Davis PhD DSc. “The future of our future ALS experiments will include…an examination of lifespan following dietary spirulina supplementation.”

5 Whole Fat Dairy Foods May Decrease Diabetes Risk

Despite the fact that most physicians and dietitians recommend lower fat dairy products, such as skim milk and reduced-fat cheese, researchers from Harvard suggest that whole fat dairy foods decrease the incidence of type 2 diabetes. The findings, based on research conducted during the Cardiovascular Health Study of 3,736 participants aged 65 and older, those with the highest levels of trans-palmitoleic acid had a 60 percent lower diabetes incident than those who had the lowest levels. The fatty acid is derived primarily from dairy and other ruminant trans fats, but is not associated with increased cardiovascular risk. The authors stress, however, that the study had limitations, including the fact that it only measured levels at a single point in time.

Increases Activity Ability

6 Beetroot Juice May Improve Senior Health

Beetroot juice, shown to be beneficial in the performance of athletes, may also have positive effects on the physical abilities of the elderly. Beetroot juice, which contains high levels of nitrate, widens blood vessels, reduces blood pressure and thereby improves circulation, explains University of Exeter doctoral student Katie Lansley. The juice also reduces the amount of oxygen the muscles need during activity, important for older adults or those with heart or lung conditions who have a decreased ability to take in enough oxygen to support even low-intensity activities. In her study, subjects used less oxygen while walking, effectively reducing the effort by 12 percent. “This could help people do things they wouldn’t otherwise be able to do,” she writes.

Time for Fat Crash Test Dummies

7 Obese People More Likely to Die in Car Crashes

Obese and morbidly obese individuals are more likely to die after a severe car crash than their normal-weight and underweight counterparts. A new study published in the American Journal of Emergency Medicine found that morbidly obese individuals have a 56 percent higher risk of death in a severe car crash, while moderately obese individuals have a 21 percent higher risk. Slightly overweight drivers have better survival chances in a severe crash than normal-weight and underweight drivers. Part of the problem is that cars aren't tested to protect overweight individuals. "Crash test dummies have saved lives and provided invaluable data on how human bodies react to crashes, but they are designed to represent normal-weight individuals," says Dietrich Jehle, MD, the lead author on the story.

Legislation Tackles Tainted Food

8 House Approves Food-Safety Bill 215-144

The House of Representatives approved the food safety bill cleared by the Senate last month with a vote of 215-144. It now awaits President Obama's signature. The legislation aims to protect consumers from tainted food and give the Food and Drug Administration the power to force importers to verify commodities' safety and demand recalls. The FDA would also have to inspect food production facilities regularly; currently, many facilities are only inspected every few years, according to the Los Angeles Times. If the bill receives President Obama's signature, it would be the first enhancement to U.S. food-safety laws since the Great Depression. The Washington Post states that the bill will cost $1.4 billion over the next four years.
