Sleep Duration, Sleep Quality, Excessive Daytime Sleepiness, And Chronotype In University Students In India: A Systematic Review, Christen Dunn, Octavia Goodman, Mariana Szklo-Coxe

Community & Environmental Health Faculty Publications

Introduction: Optimal sleep is an important aspect of academic performance and mental health. However, poor sleep health is often present among university students due to their lifestyle and academic requirements. University students in India have been shown to have poor sleep health. Though self-reported sleep issues have been evaluated among university students in India, these results have not been synthesized to date. We aimed to identify factors that may be associated with poor sleep health among university students in India from January 2010 to April 2021, inclusive. As a secondary aim, we sought to evaluate factors associated with sleep among …

An Exploratory Study Examining The Associations Between Sunlight Exposure, Sleep Behaviours And Sleep Outcomes During An Arctic Summer, Margaret M. Lubas, Ralitsa S. Maduro, Mariana Szklo-Coxe

Few evidence-based recommendations exist for maintaining healthy sleep during Arctic summers. Our study aimed to examine associations between sleep hygiene, sunlight exposure and sleep outcomes in workers living in and/or near the Arctic Circle during a 24-h light period. A survey was administered July 2017 to 19 workers at 3 Arctic base camps in Northeastern Alaska. Participants with poorer sleep hygiene reported increased sleepiness (r=.62, p=0.01); this correlation remained moderately strong, albeit not statistically significant (NS), after controlling for shift work (r=.46, p=0.06). No other statistically significant correlations between sleep hygiene and sleep outcomes were found. Weekly daytime (8pm) sunlight …

Longitudinal Association Of Sleep-Disordered Breathing And Nondipping Of Nocturnal Blood Pressure In The Wisconsin Sleep Cohort Study, Khin Mae Hla, Terry Young, Laurel Finn, Paul E. Peppard, Mariana Szklo-Coxe, Maryan Stubbs

Community & Environmental Health Faculty Publications

Study objectives: The association of sleep-disordered breathing (SDB) and blunting of normal nocturnal lowering of blood pressure (BP) (nondipping) has only been examined cross-sectionally. The purpose of this study is to investigate whether SDB is prospectively associated with nondipping.

Methods: The longitudinal association between SDB and incident nondipping was examined in a subsample of 328 adults enrolled in the Wisconsin Sleep Cohort Study who completed 2 or more 24-hour ambulatory BP studies over an average of 7.2 years of follow-up. SDB identified by baseline in-laboratory polysomnography was defined by apnea-hypopnea index (AHI) categories. Systolic and diastolic nondipping was defined by …

Depression: Relationships To Sleep Paralysis And Other Sleep Disturbances In A Community Sample, Mariana Szklo-Coxe, Terry Young, Laurel Finn, Emmanuel Mignot

Community & Environmental Health Faculty Publications

Sleep disturbances are important correlates of depression, with epidemiologic research heretofore focused on insomnia and sleepiness. This epidemiologic study’s aim was to investigate, in a community sample, depression’s relationships to other sleep disturbances: sleep paralysis (SP), hypnagogic/hypnopompic hallucinations (HH), cataplexy – considered rapid eye movement-related disturbances – and automatic behavior (AB). Although typical of narcolepsy, these disturbances are prevalent, albeit under-studied, in the population. Cross-sectional analyses (1998–2002), based on Wisconsin Sleep Cohort Study population-based data from 866 participants (mean age 54, 53% male), examined: depression (Zung Self-Rating Depression Scale), trait anxiety (Spielberger State-Trait Anxiety Inventory, STAI-T ≥ 75th percentile), and …
