Inadequate sleep predicts risk of heart disease, diabetes in obese adolescents

06.03.2014

Study suggests sleep assessment could screen kids at increased risk for cardiometabolic disease

Obese adolescents not getting enough sleep? A study in today's The Journal of Pediatrics, shows they could be increasing their risk for developing diabetes, heart disease and stroke.

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

However, the association is not as clear in adolescents, an age group known for lack of adequate sleep, and with an obesity and overweight prevalence of 30 percent in the United States.

Researchers at the University of Michigan Health System and Baylor University studied 37 obese adolescents, ages 11-17. Their risk factors for type 2 diabetes and cardiovascular disease, such as fasting cholesterol and blood sugar, waist circumference, body mass index, and blood pressure, were measured to create a continuous cardiometabolic risk score.

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. 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 impact cardiometabolic risk, like BMI and physical activity, low levels of sleep remained a significant predictor of cardiometabolic risk in obese teens.

This shows that even among those already considered at risk for cardiometabolic disease, in this case obese teens' decreased sleep duration was predictive of increased cardiometabolic risk. The study cannot determine whether lack of sleep causes cardiometabolic disease or if obesity, or other factors cause sleep disturbances.

"However, the strong association between sleep duration and cardiometabolic risk score independent of the effects of body composition and physical activity suggest a potential influence of sleep duration on cardiometabolic health in obese adolescents," says lead author Heidi IglayReger, Ph.D., supervisor of the Physical Activity Laboratory at the Michigan Metabolomics and Obesity Center.

These data provide evidence that objective sleep assessment may be a useful screening tool to identify at-risk adolescents.

Future studies are needed to determine if improving sleep duration would decrease the risk of developing cardiometabolic diseases.

Im Focus: Glaciers melt faster than ever

Glacier decline in the first decade of the 21st century has reached a historical record, since the onset of direct observations. Glacier melt is a global phenomenon and will continue even without further climate change. This is shown in the latest study by the World Glacier Monitoring Service under the lead of the University of Zurich, Switzerland.

The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together...

Im Focus: Quantum Matter Stuck in Unrest

Using ultracold atoms trapped in light crystals, scientists from the MPQ, LMU, and the Weizmann Institute observe a novel state of matter that never thermalizes.

Physicists from Regensburg and Marburg, Germany have succeeded in taking a slow-motion movie of speeding electrons in a solid driven by a strong light wave. In the process, they have unraveled a novel quantum phenomenon, which will be reported in the forthcoming edition of Nature.

The advent of ever faster electronics featuring clock rates up to the multiple-gigahertz range has revolutionized our day-to-day life. Researchers and...
