The aims of this longitudinal study were to assess: (a) the development of sleep patterns among infants, (b) the development of maternal cognitions regarding infant sleep, and (c) the relations between these domains during the 1st year of life. Eighty-five mothers were recruited during pregnancy and completed a questionnaire aimed at a...

Abstract Study Objectives Sleep plays an important role in cardiometabolic health. Although the importance of considering sleep as a multidimensional construct is widely appreciated, studies have largely focused on individual characteristics. The association between actigraphy-derived profiles and health healthy adults children has not been examined. Methods This study used actigraphy-measured ...

620 T he Multiple Sleep Latency Test (MSLT) is an important tool in the evaluation of excessive daytime sleepiness. It is indicated for the diagnosis of narcolepsy and the evaluation of idiopathic hypersomnia. 1 However, the MSLT results can be affected by a variety of extraneous variables that must be controlled or minimized to obtain interpretable diagnostic data. 2 Prior sleep deprivation is...

RESEARCH DESIGN AND METHODS—This was an ancillary study to the Coronary Artery Risk Development in Young Adults (CARDIA) Study. Habitual sleep duration and fragmentation were estimated from 6 days of wrist actigraphy collected in 2003–2005. Insomnia was defined as self-reported difficulty falling asleep or waking up in the night three or more times per week plus average sleep efficiency of ,80%...

Delayed sleep phase (and sometimes free-run) is common in the Antarctic winter (no natural sunlight) and optimizing the artificial light conditions is desirable. This project evaluated sleep when using 17,000 K blue-enriched lamps compared with standard white lamps (5000 K) for personal and communal illumination. Base personnel, 10 males, five females, 32.5±8 years took part in the study. From ...
