CDC: H1N1 Flu Killing at Epidemic Levels
The H1N1 flu virus has been killing at epidemic levels since mid-January, according to new data from the U.S. Centers for Disease Control and Prevention (CDC). While flu is known to disproportionately affect the very young and very old, this strain—also known as the swine flu and the cause of the 2009 global pandemic that killed tens of thousands—has so far caused 243 deaths of residents younger than 65 this year in California alone, with an additional 41 unconfirmed cases. In the 2012-13 season there were 26 deaths at this point and in the 2011-12 season there were nine. According o the CDC the average age of someone diagnosed with flu this season is 28.5 years. “These severe flu outcomes are a reminder that flu can be a very serious disease for anyone, including young, previously healthy adults,” CDC spokesman Jason McDonald said to The Washington Post.

Teens Who Text About Condoms, Birth Control More Likely to Use Them
Teens who talk about condoms and other types of birth control over text message and other technology are more likely to use them, according to a new study in the Journal of Adolescent Health. Researchers studied 176 high school juniors and seniors, finding that half of the 64 who reported being sexually active also failed to use condoms consistently. According to the U.S. Centers of Disease Control and Prevention, close to 40 percent of the 47 percent of high school students who reported having sex did not use a condom the last time. However, the study found that students who texted or used other private electronic technology to discuss condoms or other forms of birth control were approximately four times more likely to use them. It also found that the odds of consistently using condoms doubled among students reporting discussions of pregnancy or sexual limits. "Although prior research and media attention has focused on the risks of technology use, like sexting, we found that adolescents might also use electronic tools to communicate about ways they might promote their sexual health," said study lead author Laura Widman, who studies adolescent sexuality at the University of North Carolina at Chapel Hill. "It's not all about risky behavior. It might be another way that teens can have these conversations that can be a little bit awkward.” Read more on sexual health.
Study: Average Obese Woman Gets Only One Hour of Vigorous Exercise Each Year
The average obese woman in the United States gets only one hour of vigorous exercise each year, and the average obese man gets only 3.6 hours, according to a new study in Mayo Clinic Proceedings. The study utilized the results of a 2005-2006 government survey of adults aged 20 to 74, which covered areas such as weight, diet and sleep patterns of the nearly 2,600 adults and use accelerometer devices to track their movements. The study defined "vigorous" exercise as fat-burning activities such as jogging and jumping rope. “They're living their lives from one chair to another," said Edward Archer, a research fellow with the Nutrition Obesity Research Center at the University of Alabama at Birmingham. "We didn't realize we were that sedentary. There are some people who are vigorously active, but it's offset by the huge number of individuals who are inactive." According to the U.S. Centers for Disease Control and Prevention (CDC), approximately one in three U.S. adults is obese, which increases the risk of cardiovascular problems such as heart disease and stroke, diabetes and some cancers.
