If You're a Teen, Obese and Don't Sleep Much, You're at High Risk of Deadly Diseases

Here's another reason teens need to get their sleep.  Those who are obese and don't get enough heighten their chances of heart attack, stroke and diabetes, according to a new study.

Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases in adults and young children, newswise.com reports.

The adolescents were fitted with a physical activity monitor, worn 24 hours a day for seven days, to measure typical patterns of physical activity and sleep.
"One-third of the participants met the minimum recommendation of being physically active at least 60 minutes a day," the Web site notes. Most participants slept approximately seven hours each night, usually waking up at least once. Only five of the participants met the minimal recommended eight-and-a- half hours of sleep per night.

Even after controlling for factors that may have an impact on cardiac and metabolic risk, like BMI and physical activity, low levels of sleep remained a significant predictor of this kind of risk in obese teens.
Although the study cannot determine whether lack of sleep causes cardiometabolic disease or if obesity, or other factors cause sleep disturbances, decreased sleep duration did predict increased cardiometabolic risk.
