Sleep Quality among Homeless-Experienced Older Adults: Exploratory Results from the HOPE HOME Study.

BACKGROUND: Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults. OBJECTIVE: To examine the factors associated with poor sleep quality in a cohort of older adults in Oakland, California recruited while homeless using venue-based sampling and followed regardless of housing status. DESIGN: Longitudinal cohort study. PARTICIPANTS: 244 homeless-experienced adults aged ≥ 50 from the Health Outcomes in People Experiencing Homelessness in Older Middle Age (HOPE HOME) cohort. MAIN MEASURES: We assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI). We captured variables via biannual questionnaires and clinical assessments. KEY RESULTS: Our sample was predominantly men (71.3%), Black (82.8%), and had a median age of 58.0 years old (IQR 54.0, 61.0). Two-thirds of participants (67.2%) reported poor sleep during one or more study visits; sleep duration was the worst rated subdomain. In a multivariable model, having moderate-to-severe depressive symptoms (AOR 2.03, 95% CI 1.40-2.95), trouble remembering (AOR 1.56, 95% CI 1.11-2.19), fair or poor physical health (AOR 1.49, 95% CI 1.07-2.08), two or more chronic health conditions (AOR 1.76, 95% CI 1.18-2.62), any ADL impairment (AOR 1.85, 95% CI 1.36-2.52), and being lonely (AOR 1.55, 95% CI 1.13-2.12) were associated with increased odds of poor sleep quality. Having at least one confidant was associated with decreased odds of poor sleep (AOR 0.56, 95% CI 0.37-0.85). Current housing status was not significantly associated with poor sleep quality. CONCLUSIONS: Homeless-experienced older adults have a high prevalence of poor sleep. We found that participants' physical and mental health was related to poor sleep quality. Poor sleep continued when participants re-entered housing. Access to physical and mental healthcare, caregiving support, and programs that promote community may improve homeless-experienced older adults sleep quality, and therefore, their overall health.

COVID-19 Testing and Vaccine Acceptability Among Homeless-Experienced Adults: Qualitative Data from Two Samples.

BACKGROUND: Homeless-experienced populations are at increased risk of exposure to SARS-CoV-2 due to their living environments and face an increased risk of severe COVID-19 disease due to underlying health conditions. Little is known about COVID-19 testing and vaccination acceptability among homeless-experienced populations. OBJECTIVE: To understand the facilitators and barriers to COVID-19 testing and vaccine acceptability among homeless-experienced adults. DESIGN: We conducted in-depth interviews with participants from July to October 2020. We purposively recruited participants from (1) a longitudinal cohort of homeless-experienced older adults in Oakland, CA (n=37) and (2) a convenience sample of people (n=57) during a mobile outreach COVID-19 testing event in San Francisco. PARTICIPANTS: Adults with current or past experience of homelessness. APPROACH: We asked participants about their experiences with and attitudes towards COVID-19 testing and their perceptions of COVID-19 vaccinations. We used participant observation techniques to document the interactions between testing teams and those approached for testing. We audio-recorded, transcribed, and content analyzed all interviews and identified major themes and subthemes. KEY RESULTS: Participants found incentivized COVID-19 testing administered in unsheltered settings and supported by community health outreach workers (CHOWs) to be acceptable. The majority of participants expressed a positive inclination toward vaccine acceptability, citing a desire to return to routine life and civic responsibility. Those who expressed hesitancy cited a desire to see trial data, concerns that vaccines included infectious materials, and mistrust of the government. CONCLUSIONS: Participants expressed positive evaluations of the incentivized, mobile COVID-19 testing supported by CHOWs in unsheltered settings. The majority of participants expressed a positive inclination toward vaccination. Vaccine hesitancy concerns must be addressed when designing vaccine delivery strategies that overcome access challenges. Based on the successful implementation of COVID-19 testing, we recommend mobile delivery of vaccines using trusted CHOWs to address concerns and facilitate wider access to and uptake of the COVID vaccine.

Cerebral blood flow in 5- to 8-month-olds: Regional tissue maturity is associated with infant affect.

Infancy is marked by rapid neural and emotional development. The relation between brain function and emotion in infancy, however, is not well understood. Methods for measuring brain function predominantly rely on the BOLD signal; however, interpretation of the BOLD signal in infancy is challenging because the neuronal-hemodynamic relation is immature. Regional cerebral blood flow (rCBF) provides a context for the infant BOLD signal and can yield insight into the developmental maturity of brain regions that may support affective behaviors. This study aims to elucidate the relations among rCBF, age, and emotion in infancy. One hundred and seven mothers reported their infants' (infant age M ± SD = 6.14 ± 0.51 months) temperament. A subsample of infants completed MRI scans, 38 of whom produced usable perfusion MRI during natural sleep to quantify rCBF. Mother-infant dyads completed the repeated Still-Face Paradigm, from which infant affect reactivity and recovery to stress were quantified. We tested associations of infant age at scan, temperament factor scores, and observed affect reactivity and recovery with voxel-wise rCBF. Infant age was positively associated with CBF in nearly all voxels, with peaks located in sensory cortices and the ventral prefrontal cortex, supporting the formulation that rCBF is an indicator of tissue maturity. Temperamental Negative Affect and recovery of positive affect following a stressor were positively associated with rCBF in several cortical and subcortical limbic regions, including the orbitofrontal cortex and inferior frontal gyrus. This finding yields insight into the nature of affective neurodevelopment during infancy. Specifically, infants with relatively increased prefrontal cortex maturity may evidence a disposition toward greater negative affect and negative reactivity in their daily lives yet show better recovery of positive affect following a social stressor.

Continued Homelessness and Depressive Symptoms in Older Adults.

Importance: Depression is common in adults experiencing homelessness. It is unclear whether continued homelessness is associated with more depressive symptoms. Objective: To examine the association between residential status and depressive symptoms in adults aged 50 years or older experiencing homelessness at study entry. Design, Setting, and Participants: This cohort study analyzed results from the Health Outcomes of People Experiencing Homelessness in Older Middle Age (HOPE HOME) project, which in 2013 began enrolling adults aged 50 years or older experiencing homelessness in Oakland, California, and conducted structured interviews every 6 months for a mean duration of 5.5 years through 2023 (for this cohort study). Eligible participants included those aged 50 years or older, able to speak English, and experiencing homelessness at enrollment. We analyzed data collected from 2013 to 2023. Exposures: The exposure of interest was residential status. At follow-up visits, residential status was categorized as (1) homelessness (meeting the HEARTH [Homeless Emergency Assistance and Rapid Transition to Housing] Act definition) or (2) housed (living in a noninstitutional environment and not meeting the HEARTH Act definition). Main Outcomes and Measures: The primary outcome was moderate to severe depressive symptoms (with Center for Epidemiologic Studies-Depression [CES-D] scale score ≥22). The augmented inverse probability of treatment weighting (AIPTW) approach was used to examine the association between continued homelessness and depressive symptoms. The AIPTW adjusted for the following variables: number of chronic health conditions, age, sex, visiting a health care practitioner, receiving outpatient mental health treatment, receiving mental health medication, exposure to abuse, substance use disorder, and binge drinking. Results: The cohort was composed of 450 participants, of whom 343 (76.2%) were males, and the mean (SD) age was 58.5 (5.2) years. Participants completed a median (IQR) of 8.9 (8-11) follow-up visits. With 1640 person-years of observation time, participants continued homelessness for 880 person-years (57.1%) and experienced being housed for 715 person-years (44.3%). Many participants (304 [78.0%]) were housed during at least 1 follow-up visit. The odds of a CES-D scale score of 22 or higher was significantly higher among participants who continued experiencing homelessness than among housed participants (marginal causal odds ratio, 1.08; 95% CI, 1.04-1.11; P < .001). Conclusions and Relevance: This cohort study found that continued homelessness was associated independently with increased odds of depressive symptoms. Obtaining housing may have a favorable role in depression and overall well-being of older adults experiencing homelessness and may be considered as a mental health intervention.

"We Remember the Pain": A qualitative study of intergenerational trauma among older adults experiencing homelessness in the HOPE HOME study.

Rates of homelessness among adults aged 50 and over are rising. Common strategies for exiting homelessness rely on social and family support. However, intergenerational trauma may disrupt these social support networks and contribute to homelessness. Understanding the impact of intergenerational trauma on living with family or friends may give insight into addressing homelessness among older adults. We purposefully sampled 46 adults who reported living with family or friends from the HOPE HOME study cohort (350 community-recruited adults, ≥ 50 years and experiencing homelessness in Oakland, California) and 19 family/friends who had hosted the participants in their living spaces. We conducted independent, semi-structured interviews and used grounded theory methodologies to analyze data. We identified four major themes from the interviews: (1) Intergenerational trauma was common and made it difficult to stay with family or friends; (2) Participants and hosts sought to protect future generations from intergenerational trauma; (3) Relationships endured despite intergenerational trauma; and (4) social structures exacerbated the impact of intergenerational trauma and played a significant role in perpetuating homelessness. Trauma-informed policies that confront the structures that propagate or exacerbate intergenerational trauma may mitigate their impact and facilitate housing for older adults.
