Pediatric bipolar disorder (BD) rates have notably increased over the past three decades. Given the significant morbidity and mortality associated with BD, efforts are needed to identify factors useful in earlier detection to help address this serious public health concern. Sleep is particularly important to consider given the sequelae of disrupted sleep on normative functioning and that sleep ...

Few studies have examined relationships among neurophysiological, psychological, and behavioral factors with regard to their effects on sleep quality. We used a structure equation model to investigate behavioral and psychological factors that influence neurophysiological regulation of sleep in shift workers. Using a cross-sectional study design, we tested the model with a sample of 338 female n...

Abstract Chronotype refers to the time of day that people prefer be active or sleep and varies predictably across lifespan. In younger samples, morning-chronotype is related greater levels physical activity (PA) improved health outcomes. It unclear whether this pattern holds in older adults, a group commonly exhibits an “early bird” preference. We investigated differences PA patterns between ch...

Abstract Introduction Students’ lifestyles change after entering the university negatively impacting effective sleep regulation, daytime alertness, motivation to learn, and mental health. An evening chronotype has been increasingly associated with negative impacts upon performance well-being. Greater understanding of differences in sleep-related, health, daily life characteristics is needed dev...

Abstract Nightshift work can negatively impact sleep, performance, and health. Careful manipulation of light exposure patterns help reduce these negative effects but is challenging in conditions rapidly rotating shiftwork due to individual differences. As chronotype related tolerance, we explored sleepiness, during the first day nightshift between earlier later chronotypes, based on data from a...
