Abstract
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.
