Bidirectional links between sleep and pain among heavy-drinking veterans with insomnia.

Study Objectives: Military veterans often suffer from chronic pain and sleep issues at a greater frequency than the general population, leading some to self-medicate with alcohol. While research shows a connection between sleep and pain, few studies have examined bidirectional links between sleep and pain at the daily level-or the extent to which alcohol use may moderate these associations.

Methods: Heavy-drinking veterans seeking treatment for insomnia ( = 109, 82.

Associations between neighborhood factors and insomnia and their spatial clustering in Philadelphia, Pennsylvania.

Background: Neighborhood-level adverse social determinants may be a risk factor for sleep health disparities. We examined the associations between neighborhood factors and insomnia and explored their spatial clustering in the city of Philadelphia, Pennsylvania.

Methods: We conducted a cross-sectional analysis of data from Philadelphia residents who participated in online screening for insomnia-related research.

Sleep Disturbances Associated With Posttraumatic Stress Disorder.

Sleep disturbances, namely insomnia and recurrent nightmares, are ubiquitous following trauma exposure and are considered hallmarks of posttraumatic stress disorder (PTSD). Other sleep disorders frequently co-occur with PTSD. This article describes research examining sleep problems most common in PTSD, including prevalence and clinical characteristics.

Objective and subjective sleep patterns and biomarkers of stress among women with a history of sexual abuse in childhood.

Objective: Childhood sexual abuse (CSA) is associated with posttraumatic stress symptoms (PTSSs) and sleep disturbance into adulthood. The latter is thought to emerge from dysregulation in biobehavioral systems, including nighttime hyperarousal; however, studies investigating specific mechanisms to explain these long-term sleep problems are limited. The present study examined presleep arousal, fear of sleep, and the cortisol awakening response (CAR) as putative mediators between PTSS and sleep disturbance in women with a history of CSA.

Neighborhood disadvantage is associated with sleep disturbance in a sample of trauma-exposed Veterans.

Objectives: This study examined associations among neighborhood disadvantage, all-night respiratory sinus arrhythmia, fear of sleep, nightmare frequency, and sleep duration in a sample of trauma-exposed Veterans.

Methods: Participants completed baseline assessments and slept on a mattress actigraphy system for seven nights. Neighborhood disadvantage was assessed with the Area Deprivation Index, a census-based socioeconomic index.

Prospective associations between pre-sleep electronics use and same-night sleep in healthy school-aged children.

Electronic devices are routinely associated with adverse effects on sleep; however, prospective studies among healthy children are unavailable. This study examined relationships among specific and total electronic device use within the hour before bed and same-night sleep patterns among 55 pre-pubertal children (7-11 years) without medical, psychiatric or sleep disorders. Sleep was assessed via subjective reports and actigraphy for 5 weeknights and pre-bed device use was assessed via daily diary.

Validation of the Mental Health Checklist (MHCL) during COVID-19 lockdown.

The COVID-19 pandemic resulted in unprecedented disruption to everyday life, including widespread social distancing and self-quarantining aimed at reducing the virus spread. The Mental Health Checklist (MHCL) is a measure developed to assess psychological health during extended periods of isolation and confinement, and has shown strong psychometric properties in community samples and during Antarctic missions. This study validated the MHCL in a sample of 359 U.

Main and Interactive Effects of Nicotine Product Type on Sleep Health Among Dual Combustible and E-Cigarette Users.

Background And Objectives: E-cigarette use is associated with concurrent use of combustible cigarettes among adults and may increase the risk of future combustible cigarette use in adolescents and young adults. Detrimental effects of combustible cigarette use on sleep health are well documented, but little is known about the additive effects of concurrent e-cigarette use. The current study examined the main and interactive effects of daily nicotine product frequency on various components of sleep health.

Bidirectional relationships between sleep and biomarkers of stress and immunity in youth.

Insufficient sleep during childhood can lead to physical and mental health issues. In adults, sleep disturbances have been associated with altered levels of stress hormones and inflammatory cytokines, but data in youth is lacking. The aim of this study was to explore relationships between objective measures of sleep and salivary biomarkers in children and adolescents.

Which objective sleep elements predict children's perceptions of good sleep quality? A preliminary investigation based on polysomnography and actigraphy.

Objectives: Objective sleep elements that underlie child ratings of sleep quality are largely unknown. Child-based sleep recommendations, therefore, typically focus on duration. An expert panel recently provided specific recommendations regarding objective sleep parameters that correspond with higher quality sleep, but child-based studies from which to draw conclusions were notably limited.

Combat exposure, post-traumatic stress symptoms, and health-related behaviors: the role of sleep continuity and duration.

Study Objectives: Aggression, substance misuse, and other health risk behaviors are common among combat veterans. We examined whether sleep quality and quantity predict the association between combat exposure, post-traumatic stress symptoms, and adverse health-related behaviors.

Methods: Soldiers (N = 2420) from a brigade combat team completed surveys assessing combat experiences, and psychological and behavioral health factors, approximately 3 months following deployment to Afghanistan in 2011.

Limited Efficacy of Caffeine and Recovery Costs During and Following 5 Days of Chronic Sleep Restriction.

Objectives: To investigate the effects of caffeine on psychomotor vigilance and sleepiness during sleep restriction and following subsequent recovery sleep.

Methods: Participants were N = 48 healthy good sleepers. All participants underwent five nights of sleep satiation (time-in-bed [TIB]: 10 hours), followed by five nights of sleep restriction (TIB: 5 hours), and three nights of recovery sleep (TIB: 8 hours) in a sleep laboratory.
