Research abstracts being presented as oral presentations this afternoon at SLEEP 2008 link sleep problems to attention-deficit/hyperactivity disorder (ADHD) and suicidal symptoms.
In a study of 882 ninth-grade students (ID# 0321), teens reported sleeping an average of 7.6 hours per school night. According to the American Academy of Sleep Medicine, teens need a little more than nine hours of sleep each night.
Getting less sleep on school nights increased students’ risk of having emotional disturbances and ADHD. Every additional hour of sleep on school nights decreased the risk of emotional disturbance by 25 percent and decreased the risk of ADHD by 34 percent.
In another study of 322 undergraduates at a large university (ID# 0958), sleep quality and insomnia severity were significantly associated with an increased risk of depression. Severe insomnia also was a significant predictor of an increased severity of suicidal thoughts. After controlling for depression, sleep quality and insomnia severity jointly predicted an increased severity of suicidal thoughts.
