This research letter discusses the experience of violence during homelessness, its impact on health, and recommendations for intervention. In the California Statewide Study of People Experiencing Homelessness, 38% of participants experienced violence during their current homelessness episode, and 74% of participants reported experiencing violence at some point in their lives. These results highlight the need to address violence against people experiencing homelessness through safer housing options, trauma-informed care, and long-term violence prevention strategies.

Existing literature on people experiencing homelessness (PEH) draws on non-representative samples from service providers, populations with comorbidities, or areas with disproportionately high sheltered homelessness, leading to bias. Nearly a third of PEH in the US and over half of unsheltered PEH live in California. Researchers from the UCSF Benioff Homelessness and Housing Initiative designed a rigorous state-representative survey of PEH to investigate the antecedents of homelessness, understand health, and inform policy solutions. This is the first large representative study of PEH, beyond a single county, to draw inference on a large population that did not depend on service utilization.

Intimate partner violence (IPV) is a risk factor for people experiencing homelessness. Few studies have examined the interplay between IPV, homelessness, and housing. Researchers purposefully sampled 104 adults who reported experiencing IPV in the California Statewide Study of People Experiencing Homelessness (CASPEH), a representative, mixed-methods study. They identified six primary themes regarding IPV and homelessness.

Loneliness is often more common in older adults and those who face structural vulnerabilities, including those who experience homelessness. In the United States, 48% of single homeless adults are 50 and older. There is a limited information about loneliness among older adults who have experienced homelessness. This study used qualitative data collected as part of a longitudinal mixed-methods study, Health Outcomes of People Experiencing Homelessness in Older Middle Age (HOPE HOME). The study aimed to examine the intersection between social isolation, functional and cognitive impairment, and use of supportive services among a cohort of older adults experiencing homelessness in Oakland, California. Researchers found that homeless-experienced older adults with cognitive or functional impairments exhibited diverse loneliness experiences.

This paper describes the qualitative component of a large mixed method study, the California Statewide Study of People Experiencing Homelessness. The qualitative study consisted of seven sub-studies across eight counties, each exploring different dimensions of homelessness. BHHI researchers recruited participants from the overall sample, a statewide representative sample of adults experiencing homelessness recruited in eight counties, based on their responses to questions from the survey interviews. The researchers' mereological study design presents an approach for developing complex qualitative policy studies across a range of topic areas.

Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults. This exploratory study examined the factors associated with poor sleep quality in a cohort of older adults in Oakland, California. Researchers found that participants had higher prevalence of poor sleep and worse Pittsburgh Sleep Quality Index (PSQI) scores than in studies of housed adults 20 years older.

Little is known how older adults with a current or recent experience of homelessness navigated the switch to telehealth during the COVID-19 pandemic. Researchers examined the perceptions and use of telehealth, sampling from a larger longitudinal study on homeless-experienced adults in Oakland, CA. They found that the participants experienced challenges accessing the necessary technologies for telehealth.

In this cohort study, UCSF BHHI researchers found that most older homeless-experienced adults needed caregiving assistance and few received such assistance. Interventions that increase caregiving access for homeless-experienced individuals may help avoid poor health outcomes and costly long-term care needs due to untreated disabilities.

In this long-term study of 450 homeless adults age 50 and older, BHHI researchers examined how factors like regaining housing, using drugs, and having various chronic conditions, such as diabetes, affected participants' risk of dying. They found that 26% of the participants died within a few years of being enrolled, and people who first became homeless at age 50 or older were about 60% more likely to die than those who had become homeless earlier in life, and those who remained homeless were about 80% more likely to die than those who were able to return to housing. These findings illustrate an urgent need for policy approaches to prevent and end homelessness among older adults in the United States and suggest that addressing older adults’ barriers to health care and high rates of institutionalization may prevent premature mortality.

The homeless population in the United States is aging, however, there is limited studies on the neurologic etiologies of cognitive impairment in this population. Researchers observed a wide range of focal neurological deficits in the study participants, most notably deficits in cranial nerve function, motor function, coordination, and peripheral sensory functions. This study lays the foundation for the development of a longitudinal study of neurocognitive health among unhoused older adults in San Francisco.

Recently the demographic characteristics of people experiencing individual homelessness have changed; more individuals over the age of 50 are experiencing homelessness. BHHI researchers examined the motivations for and challenges of older adults experiencing homelessness staying with or moving in with family or friends. Researchers found barriers to stay such as feelings of shame and concerns about burdening the hosts. Findings suggest that family members and friends may play an important role in supporting older adults experiencing homelessness.

The homeless population is aging and adults who experience homelessness for the first time in older age are more likely to progress to chronic homelessness. To prevent or delay homelessness, many people live temporarily live with family or friends. In this qualitative study of homeless older adults, researchers conducted 46 semi-structured interviews. They found that structural barriers to family and friends providing housing for temporary or permanent exits from homelessness included housing regulations, geographic and transportation challenges, and environments inconducive to older adults.

The homeless population is aging and people experiencing homelessness are at a heightened risk of experiencing physical and sexual victimization. This study examined whether homelessness is independently associated with experiencing physical or sexual abuse. Researchers found that older homeless adults experience high rates of victimization.
