Objective

Although commuting time is an extension of working hours, few studies have examined the relationship between commuting time and insomnia symptoms in relation to working time. Thus, this study investigated the relationship between commuting time and working time and their link to sleep disturbance.

Methods

This study included employees with ≥35 weekly working hours (n = 30,458) using data from the Sixth Korean Working Conditions Survey conducted in Korea between October 2020 and April 2021. The association between commuting time (≤60, 61-120, and >120 minutes) and insomnia symptoms based on working hours (35-40, 41-52, and >52 h/wk) or shift work was investigated using survey-weighted logistic regression analysis.

Results

Long commuting time (>120 min/d) combined with >52 working hours/week (OR: 7.88, 95% CI: 2.51-24.71) or combined with 41-52 h/wk (OR: 3.64, 95% CI: 2.15-6.14) was associated with a higher risk of insomnia symptoms compared with the reference group (working hours: 35-40 h/wk; daily commuting time: ≤60 minutes), after controlling for sex, age, socioeconomic factors, and work-related factors. Among shift workers, those with daily commuting time ≤60 minutes (OR: 1.71, 95% CI: 1.39-2.09), 61-120 minutes (OR: 2.63, 95% CI: 1.21-5.74), and >120 minutes (OR: 5.16, 95% CI: 2.14-12.44) had higher odds of insomnia symptoms than nonshift workers with ≤60 minutes daily commuting time.

Conclusion

Long working hours and shift work are associated with greater risk of insomnia symptoms.

Objectives

To examine the association of biopsychosocial stress indicators (perceived stress, perceived discrimination, stressful life events, and allostatic load) with sleep outcomes (sleep duration and insomnia symptoms) and to examine sex and age interactions for associations between stress and sleep in older Puerto Rican adults.

Methods

Secondary analyses were performed with 830 participants (72% female) from wave 2 (2006-2011) of the Boston Puerto Rican Health Study (BPRHS), a prospective population-based cohort study (45-75 years at baseline) and Boston Puerto Rican Osteoporosis Study (BPROS) (2007-2012), an ancillary study of the BPRHS. Recruitment occurred in randomly selected census blocks using door-to-door and community-based activities. In-home data collection visits included a baseline assessment and follow-up interviews. Questionnaires assessed perceived stress, discrimination, stressful life events, and sleep. Allostatic load indicators were measured objectively. Regression models controlled for sociodemographic, behavioral, and health factors, with interaction analyses, followed by sex- and sex-by-age-stratified analyses.

Results

In the prior 2 years, participants with chronic stress had 50% greater odds of reporting nonoptimal sleep duration (<7 or >9 hours). Life events trajectories were significantly related to insomnia symptoms. Men ≥65 years who experienced chronic stress had greater insomnia symptoms than women, or than men with low stress or acute stress.

Conclusions

Stressful life events may affect sleep duration and insomnia symptoms among older Puerto Rican adults, particularly men 65 years and older who experienced chronic stress. Given the differences in sleep patterns experienced by older adults and their relationships with health outcomes, identifying methods to support sleep health among those with chronic stress is important.

Objectives

In this research, we conceptualize status-striving sleep deprivation disclosure as talking about one’s lack of sleep with the intention of enhancing one’s image. We propose that workers may disclose discretionary information about their sleep deprivation to highlight their potential contributions to the group because of the personal costs of sleep deprivation (e.g., physiological and psychological impediments), which in turn, predicts higher status conferral. We further propose that perceptions of status-striving sleep deprivation disclosure are influenced by gender stereotypes.

Methods

To test our theory, we designed three studies: an experimental study (study 1), a two-wave panel multisource field study (study 2), and another experimental study (study 3).

Results

The results showed that status-striving sleep deprivation disclosure predicted status conferral, and this indirect effect was explained by perceptions of strength for men. We also found support that when team performance ambiguity is lower, which meant that members’ contributions are more well-known within the group, the indirect effect was explained by perceptions of self-sacrifice for women.

Conclusion

People talk about sleep deprivation in their workplaces and can gain status for having done so. For men, status-striving sleep deprivation disclosure enhances their status by enhancing others’ perception of their strength. For women, status-striving sleep deprivation disclosure enhances their status by enhancing others’ perception of their self-sacrifice, but only under conditions of low team performance ambiguity.

Objectives

Short sleep duration has been associated with an increased risk of childhood overweight and obesity in high-income countries, but data from low- and middle-income countries are scarce. Independently, short sleep and food insecurity may increase the risk of overweight/obesity, but it is unknown whether they concurrently affect it.

Methods

We included 3350 adolescents aged 10-14 from the 2012 and 2016 Mexican National Health and Nutrition Survey. Short sleep was categorized as less than 9 hours for ages 10-12 and less than 8 hours for ages 13-14. Overweight/obesity was assessed via anthropometry. Modified Poisson regression models assessed prevalence ratios between short sleep and overweight, examining effect modification by food security status.

Results

86% met sleep duration recommendations. Short sleep was associated with an increased prevalence of overweight/obesity (prevalence ratio, 1.16; 95% CI, 1.05, 1.31). Multiplicative interaction was found between low and very low food security status and short sleep: adolescents in low food secure households with short sleep had 1.38 (95% CI: 1.10, 1.75) times the prevalence of overweight/obesity compared to adequate sleepers. Very low food secure households had 1.16 (95% CI: 1.14, 1.31) times the prevalence compared to adequate sleepers. This association was not significant in fully or marginally food secure households.

Conclusions

Short sleep is associated with an increased obesity risk among Mexican adolescents 10-14 years, particularly in the context of low and very low food security. These findings highlight the importance of addressing both sleep hygiene and food security in strategies to reduce obesity risk.

Objective

People who use opioids are vulnerable to sleep disturbances due to a range of factors, including the substances they use and the various structural vulnerabilities they face. We aimed to understand the burden of sleep-related impairment and problems pertaining to sleep context and schedule among people who use opioids.

Methods

We explored sleep quality and problems among a suburban sample of people who use opioids experiencing extensive structural vulnerabilities (N = 170). Participants reported their most urgent concern in the past week (e.g., sleep, drug use, housing), their sleep context, sleep problems, sleep schedules, and scores on the PROMIS Sleep-Related Impairment measure. We then quantified associations between Sleep-Related Impairment scores and sociodemographics and substance use.

Results

Participants were primarily men (66%) and non-Hispanic Black (67%) with a mean age of 42 (SD: 12.1). Many experienced hunger (44%) and literal homelessness (40%). One-quarter (28%) reported that sleep was their most urgent concern in the past week. The most common problems when falling or staying asleep were mental health-related symptoms (81%) and pain/discomfort (32%). Literal homelessness (β = 2.2, 95% CI: 0.6, 3.7), hunger (β = 2.3, 95% CI: 1.0, 3.6), and frequent alcohol use (β = 1.5, 95% CI: 0.2, 2.7) were significantly associated with Sleep-Related Impairment scores.

Conclusions

Homelessness and hunger are associated with sleep-related impairment in people who use opioids. Poor sleep quality, substance use, structural vulnerability, and mental health problems are all interrelated sources of functional impairment in this population. Interventions that address poverty as an underlying cause of sleep-related impairment and provide safe sleeping environments are needed.

Objectives

Parental interpartner conflict is a highly prevalent form of family risk that is stressful for adolescents with ramifications for their sleep. Multiple studies have demonstrated that adolescents from high-conflict homes are at risk for sleep problems. Building on this literature, we conducted novel analyses and investigated whether exposure to interpartner conflict in adolescence predicts sleep problems in the subsequent developmental period of emerging adulthood.

Methods

We used a rigorous four-wave design spanning 8 years (collected between 2012-2020). At wave 1, participants were 245 adolescents from diverse backgrounds (M age = 15.74 years; 67% White/European American, 33% Black/African American; 52% girls). Individuals participated again in their adolescence at wave 2 (M age = 16.77) and wave 3 (M age = 17.69). Participants returned for wave 4 in emerging adulthood (M age = 22.97). Adolescents reported on their parents’ interpartner conflict (intense and frequent conflict). Sleep duration (minutes) and quality (efficiency, long wake episodes) were measured using actigraphy.

Results

After controlling for autoregressive effects and several covariates, findings from a structural equation model revealed that greater exposure to parental interpartner conflict in adolescence predicted reduced sleep efficiency and more long wake episodes in emerging adulthood.

Conclusions

Results build on the literature to consider sleep in the family context and are among the first to illustrate that exposure to parental interpartner conflict in adolescence predicts sleep problems in emerging adulthood. Continued investigations into the antecedents of sleep problems in emerging adulthood may benefit from considering past exposure to family risk.

Background

Public health measures in response to the COVID-19 pandemic forced individuals to spend more time at home. We sought to investigate the relationship between housing characteristics and sleep duration in the context of COVID-19.

Methods

Our exploratory study was part of the COvid-19: Health and Social Inequities across Neighborhoods (COHESION) Study Phase-1, a pan-Canadian population-based cohort involving nearly 1300 participants, launched in May 2020. Sociodemographic, household and housing characteristics (dwelling type, dissatisfaction, access to outdoor space, family composition, etc.), and self-reported sleep were prospectively collected through COHESION Study follow-ups. We explored the associations between housing and household characteristics and sleep duration using linear regressions, as well as testing for effect modification by income satisfaction and gender.

Results

Our study sample involved 624 COHESION Study participants aged 50 ± 16 years (mean ± SD), mainly women (78%), White (86%), and university graduates (64%). The average sleep duration was 7.8 (1.4) hours. Sleep duration was shorter according to the number of children in the household, income dissatisfaction, and type of dwelling in multivariable models. Sleep was short in those without access to a private outdoor space, or only having a balcony/terrace. In stratified analyses, sleep duration was associated with housing conditions dissatisfaction only in those dissatisfied with their income.

Conclusion

Our exploratory study highlights the relationship between housing quality and access to outdoor space, family composition and sleep duration in the context of COVID-19. Our findings also highlight the importance of housing characteristics as sources of observed differences in sleep duration.

Objectives

To examine differences in psychological detachment from work during nonwork time by nurses’ personal and work-related characteristics, and to examine the moderating and mediating effects of psychological detachment on the relationships between nursing workload and fatigue and sleep.

Methods

This study employed a cross-sectional design with a self-administered online survey. Survey data from 827 hospital nurses providing direct patient care in the United States were used. Moderating and mediating effects of psychological detachment between workload and fatigue/sleep relationships were assessed using Hayes’ PROCESS macro in SPSS.

Results

There were significant differences in psychological detachment from work based on age, highest nursing degree, work experience, shift length, weekly work hours, and frequency of providing care to patients with COVID-19. The associations of workload with physical fatigue, mental fatigue, and sleep quality were weakened when psychological detachment was high. Psychological detachment statistically mediated the associations between workload and fatigue and sleep problems.

Conclusion

Healthcare organizations are encouraged to facilitate nurses’ psychological detachment during time-off to protect them from fatigue and sleep problems.

Objectives

African American children are documented as having poor sleep health due to shorter sleep duration, sleep timing, and sleep behaviors compared to White peers, contributing to child health disparities. Identifying cultural-environmental, and societal factors impacting a child’s sleep among African American families is essential for developing interventions for this population.

This study evaluated holistically why African American children may have poorer sleep health by examining sleep duration, timing, and behaviors. This was assessed by examining sleep-related beliefs, barriers, and facilitators to sleep schedules and routines. We also explored parental ideas for a sleep intervention.

Methods

African American mothers of preschool-aged children (2-5 years) were recruited using local partnerships and social media. Individual semistructured interviews were conducted by phone. Interviews were transcribed, coded, and analyzed thematically using grounded-theory.

Results

Eighteen African American mothers completed the study. Five themes related to sleep emerged: The importance of adequate nighttime sleep, the influence of family and friends on parental sleep practices, the relationship between environmental and home dynamics on child sleep duration, the impact of acute and chronic societal-level stressors on family sleep health, and considerations for culturally tailored interventions to improve child sleep health.

Conclusions

Good sleep health was important among African American mothers. Cultural-environmental and societal factors significantly impact children's sleep health. Clinicians and researchers should be aware of financial resources and home dynamics leading to challenges with adequate sleep health when developing or adapting sleep interventions. Identifying cultural-environmental, and societal factors must be considered for targeted efforts to improve sleep health in African American children.

Objectives

Similar to women overall, Black women are socialized to be communal and “self-sacrificing,” but unlike women from other racial/ethnic backgrounds, Black women are also socialized to be “strong” and “invulnerable.” This phenomenon is labeled Superwoman schema. This study examined associations between Superwoman schema endorsement and subjective sleep quality.

Methods

Participants included 405 Black women (ages 30-46). Superwoman schema was measured using a 35-item scale capturing five dimensions: obligation to present strength, suppress emotions, resistance to vulnerability, motivation to succeed, and obligation to help others. Superwoman schema overall and the five dimensions/subscales were analyzed. The Pittsburgh Sleep Quality Index (PSQI) was used to investigate overall subjective sleep quality (range: 0-19), poor sleep quality (PSQI >5), and specific sleep domains (eg, sleep duration, sleep disturbances). We fit linear and binary logistic regression models, adjusting for health-related and sociodemographic factors.

Results

Superwoman schema dimension obligation to help others was associated with lower overall subjective sleep quality (β: .81, 95%CI = 0.29, 1.32) and poor sleep quality (OR: 1.55, 95%CI = 1.10, 2.19), as well as bad subjective sleep quality (OR: 1.76, 95%CI = 1.18, 2.66), sleep disturbances (β: .73, 95%CI  = 0.07, 1.41), and daytime sleepiness (OR: 2.01, 95%CI = 1.25, 3.26). Suppress emotions (OR: 1.41, 95%CI = 1.01, 1.99) was associated with poor subjective sleep quality. Superwoman schema overall was associated with daytime sleepiness (OR: 2.01, 95%CI = 1.06, 3.82).

Conclusion

Superwoman schema endorsement, especially obligation to help others and suppress emotions, may be important psychosocial risk factors for Black women’s sleep health.
