RESUMEN
Study Background/Objectives: Sleep is an underexplored factor in the health of people involved in the criminal legal system. This study addresses the paucity of research on how individual, social, and physical environmental factors impact sleep health during and after incarceration by highlighting the voices of people involved in the criminal legal system through a community-engaged qualitative research approach. Methods: We conducted 20 semi-structured interviews with men recently released from prison for a study on trauma and healthcare during incarceration and after release. Interviews were coded and analyzed using reflexive thematic analysis and a critical realist framework. Our research team included people with a history of incarceration who performed central roles in the research process. Results: Three themes emerged from participants' descriptions of sleep during and after incarceration: (1) concerns about health contributing to sleep problems, (2) lack of access to treatment for sleep disorders leading to ongoing sleep problems, and (3) issues of safety contributing to sleep problems during incarceration and after release. Conclusions: This study identifies factors and domains influencing sleep during and after incarceration. By identifying which interpersonal, environmental, and structural factors impact sleep quality, medical and carceral staff are better equipped to ameliorate sleep health disparities within populations with a history of incarceration and those actively bound by the criminal legal system. Future research should examine other factors impacting sleep in incarcerated and recently released populations and develop multi-level interventions to improve sleep health. This paper is part of the Sleep and Circadian Health in the Justice System Collection.
RESUMEN
OBJECTIVES: To evaluate age-related differences in sleep-wake symptoms. DESIGN: Cross-sectional. SETTING: Technologist-attended, laboratory-based polysomnography (PSG). PARTICIPANTS: Community-dwelling adults aged 20 to 89 (N = 201): 52 aged 18 to 39, 72 aged 40 to 59, and 77 aged 60 and older. MEASUREMENTS: Medical burden (Charlson Comorbidity Index, medications, health status), PSG-defined sleep disorders (sleep-disordered breathing (SDB), sleep-associated hypoxemia, periodic limb movements in sleep (PLMS)), sleep-wake symptoms (Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), fatigue (Facit-F Scale)). RESULTS: Medical burden increased significantly with age (Charlson Comorbidity Index and number of medications, P < .001; health status, P = .005). Severity of sleep disorders also increased significantly with age (SDB and hypoxemia, P < .001; PLMS, P = .008). Conversely, sleep-wake symptoms decreased with age (daytime drowsiness (ESS ≥ 10), P = .02; insomnia (ISI ≥ 8), P = .04; fatigue, P < .001). In adjusted models, a 1-year increase in age was significantly associated with a 4% decrease in the odds of having daytime drowsiness (odds ratio (OR) = 0.96, 95% confidence interval (CI) = 0.93-0.98). Similarly, but only in those with mild SDB, a 1-year increase in age was significantly associated with a 5% decrease in the odds of having insomnia (OR = 0.95, 95% CI = 0.92-0.99). CONCLUSION: Older age was characterized by less-severe sleep-wake symptoms (daytime drowsiness, insomnia, fatigue), despite an age-related increase in disease severity (medical burden, sleep disorders). Because the increase in disease severity included well-established risk factors for having sleep-wake symptoms, the age-related decrease in sleep-wake symptoms may reflect a decrease in symptom awareness.
