According to a research abstract presented 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.

Earlier parental-mandated bedtimes could help protect teens from depression and suicidal thoughts by lengthening sleep duration, according to a research abstract presented at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

The study by James Gangwisch, PhD, of Columbia University in New York, examined data from 15,659 adolescents. A total of 1,143 teens (7.3 percent) suffered from depression and 2,038 (13 percent) had suicidal thoughts. Adolescents with parental-mandated bedtimes at midnight or later were 25 percent more likely to suffer from depression and 20 percent more likely to have suicidal ideation compared with adolescents who had parental-mandated bedtimes of 10 p.m. or earlier.

“It is a common perception and societal expectation that adolescents do not need as much sleep as preadolescents, yet studies suggests that adolescents may actually require more sleep,” said Gangwisch. “Studies have found that adolescents do not go to bed early enough to compensate for earlier school start times, and transitions to earlier school start times have been shown to be associated with significant sleep deprivation.”

According to Gangwisch, the study supports the argument that inadequate sleep could lead to depression. “Adolescents with later parental-mandated bedtimes went to bed later, got less sleep, and were less likely to get enough sleep. Short sleep duration explained the relationship between parental-mandated bedtimes and depression, functioning as a risk factor for depression and suicidal ideation.”

Meditation may be an effective behavioral intervention in the treatment of insomnia, according to a research abstract presented at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies

Results indicate that patients saw improvements in subjective sleep quality and sleep diary parameters while practicing meditation. Sleep latency, total sleep time, total wake time, wake after sleep onset, sleep efficiency, sleep quality and depression improved in patients who used meditation.

According to principal investigator Ramadevi Gourineni, MD, director of the insomnia program at Northwestern Memorial Hospital in Evanston, Ill., insomnia is believed to be a 24-hour problem of hyperarousal, and elevated measures of arousals are seen throughout the day.

“Results of the study show that teaching deep relaxation techniques during the daytime can help improve sleep at night,” said Gourineni.

The study gathered data from 11 healthy subjects between the ages of 25 and 45 years with chronic primary insomnia. Participants were divided into two intervention groups for two months: Kriya Yoga (a form of meditation that is used to focus internalized attention and has been shown to reduce measures of arousal) and health education. Subjective measures of sleep and depression were collected at baseline and after the two-month period.

Both groups received sleep hygiene education; members of the health education group also received information about health-related topics and how to improve health through exercise, nutrition, weight loss and stress management.
