OBJECTIVES: Cross-sectional research has found that shorter and poorer sleep are associated with lower work performance and greater work-to-family conflict (WTFC). However, we know little about daily mechanisms linking sleep, work performance, and WTFC. This study tested whether previous nights' sleep was linked to next day WTFC, mediated by work performance. DESIGN: Daily interview methodology. SETTING: US extended-care workplaces. PARTICIPANTS: One hundred seventy-one female employees with children aged 9 to 17 years...

INTRODUCTION: It is established that shiftwork causes sleep loss and circadian misalignment. Individuals who work non-traditional day shifts that encroach into typical sleep times, such as those in the service and transportation sectors, may also experience sleep and circadian disruption. We aimed to determine how neurobehavioral performance and sleep would be affected by work start time among individuals working a non-traditional daytime shift pattern. METHODS: We collected sleep diaries, wrist-worn actigraphy (CamNtech, Cambridge UK), and the psychomotor vigilance task (PVT) from 44 pilots (4F) who worked a shift rotation consisting of a five-day baseline block starting in the mid-morning (baseline), five early shifts (early), five high workload midday shifts (midday), and five days of late shifts (late), each separated by 3-4 days off...

OBJECTIVES: The objective of this study is to determine to what degree sleep disturbances predict academic success, relative to other known risk factors for decreased academic performance. METHODS: We performed regression analyses on data from the Spring 2009 American College Health Association National College Health Assessment II dataset (n=55,322 students) to isolate the relative contribution of the frequency of sleep problems in the previous week to GPA and the likelihood of withdrawing from a course...

OBJECTIVES: Previous work suggests that sleep restriction (SR) reduces cognitive control and may increase negative implicit biases. Here we investigated whether SR might influence decision making on a social-evaluative task where individuals had to make judgments of threat based on facial photographs. Furthermore, we investigated the effect of changes in negative implicit biases as a result of sleep restriction on this decision-making task. DESIGN: Fourteen healthy adults underwent two 3-week counterbalanced in-laboratory stays (chronic SR and control sleep [CS] conditions)...

OBJECTIVES: Insufficient sleep negatively impacts the cardiovascular system. No study has examined the association between sleep duration and heart age (person's predicted vascular age based on cardiovascular disease [CVD] risk profile). This study examines association between sleep duration and excess heart age (EHA; difference between heart age and chronological age) among US adults. DESIGN AND PARTICIPANTS: Cross-sectional 2007-2014 National Health and Nutrition Examination Survey data for respondents aged 30-74 years without CVD or stroke (n = 12,775)...

OBJECTIVE: To examine associations between health behavior patterns and childhood obesity, and the mediating effect of sleep duration. DESIGN: Population-based survey. PARTICIPANTS: Secondary analysis of data from the Infant Feeding Practices Study (age 6 years, n = 1073). MEASUREMENTS: Mothers self-reported their child's health behaviors including physical activity (PA), screen time, sleep duration, and diet. Latent class analysis determined the child's patterns based on health behaviors...

OBJECTIVE: The objective of this study was to examine the association between perceived stress and sleep health among a sample of sexual minority men (SMM). DESIGN: Cross-sectional survey. SETTING: Paris, France. PARTICIPANTS: Gay, bisexual and other SMM users ≥18 years on a geosocial networking application in Paris, France (N = 580). MEASUREMENTS: Participants were directed to a web-based survey measuring stress, sleep health, and socio-demographics...

OBJECTIVES: To examine whether perceptions of school safety and neighborhood safety are associated with insufficient sleep during adolescence. DESIGN: The Florida Youth Substance Abuse Survey (FYSAS) is a cross-sectional study of adolescents. SETTING: The state of Florida. PARTICIPANTS: Middle-school and high-school students (n = 7,958) attending public schools in 2017. MEASUREMENTS: Based on National Sleep Foundation recommendations, sleep was categorized as insufficient (less than 7 hours) or sufficient (7 or more hours) using self-reports of average sleep duration on school nights...

OBJECTIVES: To investigate Black-White disparities in suboptimal sleep and cardiometabolic health by government-assisted rental housing status. DESIGN: National Health Interview Survey (NHIS) pooled cross-sectional data (2004-2016). SETTING: United States. PARTICIPANTS: Black and White adult participants (n = 80,880). MEASUREMENTS: Poisson regression with robust variance was used to estimate prevalence ratios (PRs) and 95% confidence intervals for self-reported unrecommended (<6 hours), short (≤6-<7 hours), and long (>9 hours) sleep duration (each separately vs recommended (≤7-9 hours)) and sleep difficulties (eg, trouble falling/staying asleep ≥3 days/week) (yes vs no) among Blacks compared to Whites within rental housing categories (government-assisted vs unassisted), separately, for men and women...

INTRODUCTION: Adequate sleep duration and quality are protective against many adverse health outcomes. Many individual-level predictors of poor sleep have been examined, but few studies have examined neighborhood-level influences. Despite known associations between neighborhood green space and sleep influencing factors (eg, physical activity, mental health), few studies have examined green space and sleep's relationship. Furthermore, little work has examined the relationship between the magnitude and type of neighborhood sounds and sleep...

OBJECTIVES: This study examined self-reported sleepiness as a pathway of effects underlying racial and socioeconomic disparities in children's academic and cognitive performance. DESIGN: The study design was longitudinal, and path modeling was used to test study hypotheses. SETTING: Data were collected from participants residing in semirural communities and small towns surrounding Auburn, AL. PARTICIPANTS: Children (N = 282; 52% boys) participated in the study when they were 9 (M = 9...

STUDY OBJECTIVES: Maternal antenatal stress may influence offspring development and behavior, but any association with child sleep is unknown. METHODS: From 2007 to 2011, we recruited pregnant women in Mexico City to the Programming Research in Obesity, Growth, Environment, and Social Stressors prebirth cohort. Mothers completed the Perceived Stress Scale (PSS, a 4-item questionnaire assessing past-month stress) and the Crisis in Family Systems measure assessing negative life events (NLEs; how many domains among the 11 assessed in which the mother experienced a stressful event in the prior 6 months)-with higher scores reflecting higher stress-and provided 5 timed salivary samples per day on 2 consecutive days, from which we derived cortisol area under the curve, slope, and awakening response...

Sleep deprivation and sleep disturbance are pervasive among military personnel during and after combat deployment. However, occupational and other constraints often influence military workers to decline behavioral health services and prescription pharmaceutical sleep aids. This article, drawing on ethnographic interviews with National Guard veterans of combat deployment, demonstrates that soldiers with sleep disturbance frequently manage symptoms without medical supervision and by using ad hoc methods including alcohol use...
