The homeless population is aging; older homeless adults may be at high risk of experiencing violent victimization. To examine whether homelessness is independently associated with experiencing physical and sexual abuse, we recruited 350 adults, aged 50 and older in Oakland, California, who met criteria for homelessness between July 2013 and June 2014. We interviewed participants at 6-month intervals for 3 years in Oakland about key variables, including housing status. Using generalized estimating equations, we examined whether persistent homelessness in each follow-up period was independently associated with having experienced physical or sexual victimization, after adjusting for known risk factors. The majority of the cohort was men (77.4%) and Black American (79.7%). At baseline, 10.6% had experienced either physical or sexual victimization in the prior 6 months. At 18-month follow-up, 42% of the cohort remained homeless. In adjusted models, persistent homelessness was associated with twice the odds of victimization (adjusted odds ratio [AOR] = 2.01; 95% confidence interval [CI]: [1.41, 2.87]). Older homeless adults experience high rates of victimization. Re-entering housing reduces this risk. Policymakers should recognize exposure to victimization as a negative consequence of homelessness that may be preventable by housing.

AimsTo examine the prevalence of and factors associated with unmet need for mental health and substance use treatment in older homeless adults.MethodsAmong 350 homeless adults aged ≥50, we examined prevalence of mental health and substance use problems and treatment. Using logistic regression, we examined factors associated with unmet treatment need.ResultsAmong those with a mental health problem, being aged ≥65 was associated with an increased odds, while having a regular healthcare provider and case manager were associated with a decreased odds of having unmet need for mental health treatment. A first homelessness episode at age ≥50 was associated with increased, while spending time in jail/prison or having a case manager was associated with decreased odds of unmet needs for substance use treatment.ConclusionOlder homeless adults have a high prevalence of unmet behavioral health treatment need. There is a need for targeted services for this population.

Difficulty performing activities of daily living ("functional impairment") is common in homeless adults aged 50 and older. However, little is known about the trajectory of these impairments, nor the extent to which these trajectories are similar to those of older adults in the general population. We identified trajectories of functional impairment in homeless adults aged 50 and older, and risk factors for differing trajectories. We conducted a prospective cohort study of 350 homeless adults, aged 50 and older, recruited via population-based sampling in Oakland, California and interviewed at 6-month intervals for up to 3 years. We assessed functional trajectories based on self-reported difficulty performing 5 activities of daily living. We used multivariable multinomial logistic regression to identify baseline risk factors for each trajectory. At baseline, participants' mean age was 58 years (SD, 5.3), 24.1% were women, 80.9% were African American, and 38.6% had difficulty performing 1 or more activities of daily living. We identified 4 distinct functional trajectories: minimal impairment in 136 participants (41.1%); persistent impairment in 81 (25.4%); partial improvement in 74 (23.5%); and decline in 28 (10.0%). Risk factors for persistent impairment included falls in the 6 months before baseline, depressive symptoms, and low physical performance. Although functional impairment improved in some homeless adults, it persisted or worsened in many others. These findings suggest that, similar to older adults in the general population, functional impairment among older homeless persons is not a transient phenomenon, but instead a chronic issue requiring long-term solutions.

PurposeTo examine attitudes toward tobacco control policies among older African American homeless-experienced smokers.ApproachA qualitative study.SettingOakland, California.ParticipantsTwenty-two African American older homeless-experienced smokers who were part of a longitudinal study on health and health-related outcomes (Health Outcomes of People Experiencing Homelessness in Older Middle Age Study).MethodWe conducted in-depth, semistructured interviews with each participant to explore beliefs and attitudes toward tobacco use and cessation, barriers to smoking cessation, and attitudes toward current tobacco control strategies including raising cigarette prices, smoke-free policies, and graphic warning labels. We used a grounded theory approach to analyze the transcripts.ResultsCommunity social norms supportive of cigarette smoking and co-use of tobacco with other illicit substances were strong motivators of initiation and maintenance of tobacco use. Self-reported barriers to cessation included nicotine dependence, the experience of being homeless, fatalistic attitudes toward smoking cessation, substance use, and exposure to tobacco industry marketing. While participants were cognizant of current tobacco control policies and interventions for cessation, they felt that they were not specific enough for African Americans experiencing homelessness. Participants expressed strong support for strategies that de-normalized tobacco use and advertised the harmful effects of tobacco.ConclusionOlder African American homeless-experienced smokers face significant barriers to smoking cessation. Interventions that advertise the harmful effects of tobacco may be effective in stimulating smoking cessation among this population.

Individuals experiencing homelessness in the United States are aging; little is known about chronic pain in this population. In a cross-sectional, population-based study, we interviewed 350 homeless individuals aged 50 years and older to describe pain experienced by older persons experiencing homelessness and to assess factors associated with chronic moderate to severe pain, defined as pain lasting ≥3 months, with a past week average severity score of 5 to 10 (scale 0-10). The median age of participants was 58 years. Participants were predominantly African American (79.6%) and male (77.3%). Overall, 46.8% reported chronic moderate to severe pain. Almost half of participants reported a diagnosis of arthritis (44.3%) and one-third reported symptoms consistent with post-traumatic stress disorder (PTSD; 32.8%). Three-quarters (75.3%) endorsed a personal history of abuse. In multivariate analyses, PTSD (adjusted odds ratio [AOR]: 2.2, 95% confidence interval [CI], 1.4-3.7), arthritis (AOR: 4.8, 95% CI, 3.0-7.8), and history of experiencing abuse (AOR: 2.4, 95% CI, 1.3-4.3) were associated with chronic moderate to severe pain. HIV status, diabetes, depressive symptoms, and substance use were not associated with pain. Clinicians should consider the management of associated mental health conditions and the sequelae of experiencing abuse in the treatment of chronic pain in older adults experiencing homelessness.PerspectiveThis article describes the prevalence and factors associated with chronic pain in older homeless adults. Almost half report chronic pain, which was associated with PTSD, arthritis, and personal history of abuse. Clinicians should address chronic pain, trauma, and the associated mental health conditions in this high-risk population.

Purpose of the studyOlder homeless adults living in shelters have high rates of geriatric conditions, which may increase their risk for acute care use and nursing home placement. However, a minority of homeless adults stay in shelters and the prevalence of geriatric conditions among homeless adults living in other environments is unknown. We determined the prevalence of common geriatric conditions in a cohort of older homeless adults, and whether the prevalence of these conditions differs across living environments.Design and methodsWe interviewed 350 homeless adults, aged 50 and older, recruited via population-based sampling in Oakland, CA. We evaluated participants for common geriatric conditions. We assessed living environment using a 6-month follow-back residential calendar, and used cluster analysis to identify participants' primary living environment over the prior 6 months.ResultsParticipants stayed in 4 primary environments: unsheltered locations (n = 162), multiple locations including shelters and hotels (n = 88), intermittently with family/friends (n = 57), and, in a recently homeless group, rental housing (n = 43). Overall, 38.9% of participants reported difficulty performing 1 or more activities of daily living, 33.7% reported any falls in the past 6 months, 25.8% had cognitive impairment, 45.1% had vision impairment, and 48.0% screened positive for urinary incontinence. The prevalence of geriatric conditions did not differ significantly across living environments.ImplicationsGeriatric conditions were common among older homeless adults living in diverse environments, and the prevalence of these conditions was higher than that seen in housed adults 20 years older. Services that address geriatric conditions are needed for older homeless adults living across varied environments.

ObjectiveTo examine whether childhood adversity is associated with depressive symptoms, suicide attempts, or psychiatric hospitalization.MethodsHistory of seven childhood adversities (physical neglect, verbal abuse, physical abuse, sexual abuse, parental death, parental incarceration, and child welfare system placement) was gathered through in-person interviews. Multivariate models examined associations between history of childhood adversities and moderate to severe depressive symptoms, lifetime history of suicide attempt, or lifetime history of psychiatric hospitalization. The study enrolled 350 homeless adults, aged 50 and older, in Oakland, California, using population-based sampling methods. Moderate to severe depressive symptoms were measured on a Center for Epidemiologic Studies-Depression Scale (≥22), self-reported lifetime history of suicide attempt, and self-reported lifetime history of psychiatric hospitalization.ResultsParticipants with exposure to one childhood adversity had elevated odds of reporting moderate to severe depressive symptoms (adjusted odds ratio [AOR]: 2.0; 95% confidence interval [CI]: 1.1-3.7) and lifetime history of suicide attempt (AOR: 4.6; 95% CI: 1.0-21.6) when compared with those who had none; the odds of these two outcomes increased with exposure to additional childhood adversities. Participants with four or more childhood adversities had higher odds of having a lifetime history of psychiatric hospitalization (AOR: 7.1; 95% CI: 2.8-18.0); no increase with fewer adversities was found.ConclusionChildhood adversities are associated with poor mental health outcomes among older homeless adults. Clinicians should collect information about childhood adversities among this high-risk population to inform risk assessment and treatment recommendations.

BackgroundThe median age of the single adult homeless population is 50 and rising. Although the prevalence of substance use decreases as individuals age, older adults now have a higher prevalence of substance use than older adults did 10 years ago. Homeless individuals have a higher prevalence of substance use disorders than the general population. However, little is known about substance use in older homeless adults.MethodsThe objective of the study was to examine prevalence of and factors associated with substance use in a population-based sample (N = 350) of homeless individuals aged 50 and older in Oakland, California. Dependent variables included moderate or greater severity illicit drug symptoms (Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) score >3) and moderate or greater alcohol symptoms (Alcohol Use Disorders Identification Test (AUDIT) score >7). Independent variables included demographics, mental health problems, and negative life course events such as physical and sexual abuse, school expulsion, and onset of homelessness.ResultsAlmost two thirds of participants, 64.6%, had moderate or greater severity symptoms for at least 1 illicit drug; 25.8% had moderate or greater severity alcohol symptoms. History of psychiatric hospitalization was associated with moderate or greater illicit drug symptoms (adjusted odds ratio [AOR] = 1.9, 1.0-3.6). The presence of major depressive symptoms was associated with moderate or greater severity alcohol symptoms (AOR = 1.8, 1.1-3.0).ConclusionsIn this sample of older homeless adults, substance use is common. There is a need for substance use treatment programs, integrated with mental health services, which are targeted towards the needs of older homeless adults.

ObjectiveThe median age of single homeless adults is over 50, yet little is known about their emergency department (ED) use. We describe use of and factors associated with ED use in a sample of homeless adults 50 and older.MethodsWe recruited 350 participants who were homeless and 50 or older in Oakland, California. We interviewed participants about residential history in the prior 6 months, health status, health-related behaviors, and health services use and assessed cognition and mobility. Our primary outcome was the number of ED visits in the prior 6 months based on medical record review. We used negative binomial regression to examine factors associated with ED use.ResultsIn the 6 months prior to enrollment, 46.3% of participants spent the majority of their time unsheltered; 25.1% cycled through multiple institutions including shelters, hospitals, and jails; 16.3% primarily stayed with family or friends; and 12.3% had become homeless recently after spending much of the prior 6 months housed. Half (49.7%) of participants made at least one ED visit in the past 6 months; 6.6% of participants accounted for 49.9% of all visits. Most (71.8%) identified a regular non-ED source of healthcare; 7.3% of visits resulted in hospitalization. In multivariate models, study participants who used multiple institutions (incidence rate ratio [IRR] = 2.27; 95% confidence interval [CI] = 1.08 to 4.77) and who were unsheltered (IRR = 2.29; 95% CI = 1.17 to 4.48) had higher ED use rates than participants who had been housed for most of the prior 6 months. In addition, having health insurance/coverage (IRR = 2.6; CI = 1.5 to 4.4), a history of psychiatric hospitalization (IRR = 1.80; 95% CI = 1.09 to 2.99), and severe pain (IRR = 1.72; 95% CI = 1.07 to 2.76) were associated with higher ED visit rates.ConclusionsA sample of adults aged 50 and older who were homeless at study entry had higher rates of ED use in the prior 6 months than the general U.S. age-matched population. Within the sample, ED use rates varied based on individuals' residential histories, suggesting that individuals' ED use is related to exposure to homelessness.

IntroductionTobacco-attributable deaths contribute significantly to the increased mortality observed among homeless adults aged 50 years or more. Little is known about the epidemiology of tobacco use among older homeless individuals. This longitudinal cohort study examines smoking behaviors and factors associated with smoking cessation among homeless individuals aged 50 years or more.MethodsWe recruited a prospective cohort of 350 homeless individuals sampled from the community in Oakland, California. At 6 months follow-up, participants reported their cigarette quit attempts and 30-day abstinence. We used multivariable logistic regression to examine factors associated with making a quit attempt at follow-up, hypothesizing that heavier smokers would be less likely to make a quit attempt.ResultsOf the 272 ever-smokers, 229 (84.2%) were current smokers (quit ratio 15.8). Among current smokers at enrollment who had a follow-up interview at 6 months, 43.6% (n = 71) reported making a quit attempt during the follow-up. Of those who reported making a quit attempt, 14.3% (n = 10) reported 30-day abstinence at follow-up. Among those who had reported making a quit attempt at follow-up, 22.5% had used nicotine replacement therapy (NRT). Staying in shelters (adjusted odds ratio [AOR] = 2.5, 95% confidence interval [CI] = 1.0-5.8) was associated with higher odds of making a quit attempt at follow-up. Higher cigarette consumption was associated with lower odds of making a quit attempt (AOR = 0.9, 95% CI = 0.8-0.9).ConclusionsIn this study of tobacco use in older homeless adults, rates of quit attempts were similar to that observed in the general population, but successful quitting was lower.ImplicationsThe current study is among the first studies to focus specifically on tobacco use and cessation behaviors among older homeless adults. The high prevalence of smoking and the low rates of successful quitting highlight numerous opportunities to intervene to increase quitting rates among this population. Among these, increasing access to smoke-free living environments and identifying effective cessation therapies will be critical to reducing tobacco-related disease burden among older homeless adults.

Adults aged 50 and older make up half of individuals experiencing homelessness and have high rates of morbidity and mortality. They may have different life trajectories and reside in different environments than do younger homeless adults. Although the environmental risks associated with homelessness are substantial, the environments in which older homeless individuals live have not been well characterized. We classified living environments and identified associated factors in a sample of older homeless adults. From July 2013 to June 2014, we recruited a community-based sample of 350 homeless men and women aged fifty and older in Oakland, California. We administered structured interviews including assessments of health, history of homelessness, social support, and life course. Participants used a recall procedure to describe where they stayed in the prior six months. We performed cluster analysis to classify residential venues and used multinomial logistic regression to identify individual factors prior to the onset of homelessness as well as the duration of unstable housing associated with living in them. We generated four residential groups describing those who were unsheltered (n = 162), cohabited unstably with friends and family (n = 57), resided in multiple institutional settings (shelters, jails, transitional housing) (n = 88), or lived primarily in rental housing (recently homeless) (n = 43). Compared to those who were unsheltered, having social support when last stably housed was significantly associated with cohabiting and institution use. Cohabiters and renters were significantly more likely to be women and have experienced a shorter duration of homelessness. Cohabiters were significantly more likely than unsheltered participants to have experienced abuse prior to losing stable housing. Pre-homeless social support appears to protect against street homelessness while low levels of social support may increase the risk for becoming homeless immediately after losing rental housing. Our findings may enable targeted interventions for those with different manifestations of homelessness.

Little is known about pathways to homelessness among older adults. We identified life course experiences associated with earlier versus later onset of homelessness in older homeless adults and examined current health and functional status by age at first homelessness. We interviewed 350 homeless adults, aged 50 and older, recruited via population-based sampling. Participants reported age at first episode of adult homelessness and their life experiences during 3 time periods: childhood (

Respiratory dysfunction is common with HIV infection, but few studies have directly assessed whether HIV remains an independent risk factor for pulmonary function abnormalities in the antiretroviral therapy era. Additionally, few studies have focused on pulmonary outcomes in HIV+ women. We tested associations between risk factors for respiratory dysfunction and pulmonary outcomes in 63 HIV+ and 36 HIV-uninfected women enrolled in the Women's Interagency HIV Study. Diffusing capacity (DL(CO)) was significantly lower in HIV+ women (65.5% predicted vs. 72.7% predicted, P = 0.01), and self-reported dyspnea in HIV+ participants was associated with both DL(CO) impairment and airflow obstruction. Providers should be aware that DL(CO) impairment is common in HIV infection, and that either DL(CO) impairment or airflow obstruction may cause respiratory symptoms in this population.
