This study was the first to use a school-based sleep intervention with a cognitive behavior framework to improve adolescents’ sleep problems, and it was also the first to use a controlled design with a long-term follow up.

A study in the March 1 issue of the journal SLEEP suggests that it is the rate of change in sleep problems across development, rather than the initial level of sleep problems, that may affect cognitive abilities in late adolescence.

This is the first study to compare in-home measurements of sleep architecture in chil¬dren with ADHD and no co-morbidities with that of con¬trols, while also controlling for potential confounders.

Findings of this study suggest that efforts to manage tension-type headache pain by going to sleep might serve as a behavioral risk factor for developing insomnia.

This study is the first to demonstrate through the use of twin studies that genetics is the most important factor in explaining the link between sleep problems early in life and the later development of depression.

The activation of pro-inflammatory cytokines may be a mechanism by which short and long sleep durations affect health.

This study is the first to evaluate the extent to which any associations between obstructive sleep apnea severity and daytime functional impairments were confounded by short sleep duration in a population-based sample of older men.

The study finds a striking association between pregnancy-related restless legs syndrome (RLS) and increased levels of the steroid hormone estradiol.

Findings show that factors other than central sleep apnea may contribute to poor sleep quality in heart-failure patients.
