When some people think about heart disease, they think primarily of older adults. However, both doctors and young patients miss opportunities to recognize symptoms of heart problems and treat them proactively, according to research presented at the American Heart Association conference.
A study discussed Tuesday found a common risk factor for heart disease - high blood pressure, or hypertension - often goes undiagnosed in younger patients.
"This research directly addresses the public health burden in the U.S. as far as rising rates of hypertension among young adults, especially with the growing rate of obesity," said Dr. Heather Johnson, lead study author from the University of Wisconsin School of Medicine and Public Health.

Lack of quality sleep for adults may negatively impact heart health. Evidence now suggests that sleep problems during adolescence may increase health risks as well.
The research appeared Monday in the Canadian Medical Association Journal.
"When most people think about cardiovascular risk factors and risk behaviors, they don't necessarily think of sleep," said Dr. Brian McCrindle, senior author and cardiologist at SickKids in Toronto, Ontario. "This study ... shows a clear association between sleep disturbance (in adolescents) and a greater likelihood of having high cholesterol, high blood pressure and being overweight or obese." FULL POST

If your adolescent is sexting, they may be already sexually active and engaging in risky behavior, a new study suggests.
Researchers are trying to better understand if young people are at greater risk for HIV or other sexually transmitted diseases because they are sending sexually explicit photos or text messages via cell phones.
"Sexting" is not an alternative to "real world" sexual behavior among adolescents, according to a new study published Monday in the journal Pediatrics.
"The same teens who are engaging in digital sex risk taking through sexting are also the same teens that are engaging in sex risk with their bodies in terms of being sexually active and not using condoms," said lead study author Eric Rice, an assistant professor at the University of Southern California's School of Social Work in Los Angeles.

Marijuana may double the risk of testicular cancer among young men, particularly tumors that are more severe, according to a new study published in the American Cancer Society's journal, Cancer.
"This is a very consistent finding now that marijuana seems to be associated with the worst kind of testis cancer that occurs in young men ... (it) may well be causal," said study author Victoria Cortessis, an assistant professor of preventive medicine at the University of Southern California's Keck School of Medicine in Los Angeles.

What would happen if the entire population of adults in the U.S. reduced the amount of time they spent sitting or watching television?
Researchers, whose work is published in the British Medical Journal Open, say Americans may live longer. They estimate a gain of two years to life expectancy for reducing sitting to less than three hours a day, or an additional 1.38 years if everybody limited the time they spent plopped in front of the television to two hours.
"Right now, if you're born in the U.S. this year, your life expectancy is 78.5 years," said Peter Katzmarzyk, Professor of Epidemiology at Pennington Biomedical Research Center in Baton Rouge, Louisiana. "What we're saying is, if you got everyone in the U.S. to sit less, that population-level life expectancy would be two years higher. Our life expectancy as a country would be 80 years."

Some people who suffer from chronic weight issues may soon get some help from a pill.
The U.S. Food and Drug Administration Wednesday approved Belviq, or lorcaserin hydrochloride, to be combined with a reduced-calorie diet and exercise, for treatment of chronic weight problems.
Specifically, the FDA says, it is approved for overweight or obese adults who have one or more medical conditions due to their weight, such as high blood pressure, type 2 diabetes or high cholesterol.

The number of hospitalizations for children with high blood pressure more than doubled from 1997 to 2006, according to a new study. The number rose from 12,661 hospitalizations in 1997 to 24,602 in 2006. The study is published in the American Heart Association journal, Hypertension.
"There have been some published studies that have demonstrated an increase in frequency of hypertension among kids in the outpatient settings in the clinics," said Dr. Cheryl Tran, study author and fellow in the Department of Pediatric Nephrology at the University of Michigan.
"In our study, we found we also are seeing this trend in the inpatient setting," she said.
"It definitely was surprising- we may be seeing a reflection of that from the rise in hypertension from the outpatient setting, but I think what was also alarming was the economic burden created by the inpatient pediatric hypertension."
The cost of the hospitalizations in the 10 years reviewed reached an estimated $3.1 billion, according to the study.

While children do not make or break friendships based on physical activity, a new study suggests their social network of friends can greatly influence how much they move. The research was published in the journal Pediatrics on Monday.
"We tend to think of teenagers as being very influential amongst their peers, but now we're seeing this in a younger age group as well," said study author Sabina Gesell, assistant professor of Pediatrics at the Vanderbilt University School of Medicine.

News flash: Texting while driving can have serious, catastrophic consequences.
All sarcasm aside, you will most likely have heard this message by now and seen the PSA's meant to convince you that this is a bad idea. You've heard that many states ban texting while driving and hopefully are heeding the warnings. But some of the youngest drivers still don't realize that it is a problem.
Some teens, however, do and are taking matters into their own hands.
Determined to educate their peers about on the dangers of texting while driving, a group of student leaders in Oklahoma started Generation tXt.
They focus on those recently behind the wheel for the first time.
