Link between sleep disorders, diet, exercise and technology use in adolescents

Jun 9 2009

According to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, adolescent obesity is associated with having less sleep. Reduction in sleep could be related to a higher caffeine intake, more hours of technology use and increased symptoms of sleep disorders (such as snoring).

Results indicate that children who slept less consumed more caffeine and had more hours of screen time (use of television, Internet, computer and video games). A higher body mass index (BMI) was also associated with shorter sleep duration. More hours of screen time were also associated with higher caffeine consumption.

According to lead author Amy Drescher, PhD, research specialist at the University of Arizona in Tucson, there are many reasons that kids gain weight, and inadequate sleep is just one of them.

"Boys had significantly more vigorous exercise, recreational activity than girls," said Drescher. "The sleep and obesity connection is not always seen because factors such as exercise may keep weight in check."

The study gathered data from 320 children who completed detailed dietary and physical activity questionnaires. Correlation and regression analysis were used to study the relationships among diet, physical activity and self-reported sleep duration and screen time. Mean age of the sample group was 13.3 years; 51.8 percent of participants were male, 65 percent were Caucasian and 35 percent were Hispanic.

Inadequate sleep combined with increased electronic screen time and caffeine intake may have negative implications for adolescents' health, psychosocial well-being and academic performance.

The annual SLEEP meeting brings together an international body of 6,000 leading researchers and clinicians in the field of sleep medicine to present and discuss new findings and medical developments related to sleep and sleep disorders.

More than 1,300 research abstracts will be presented at the SLEEP meeting, a joint venture of the AASM and the Sleep Research Society. The three-and-a-half-day scientific meeting will bring to light new findings that enhance the understanding of the processes of sleep and aid the diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.
