Psychiatric diagnoses of medical service users: evidence from the Epidemiologic Catchment Area Program.

Based on data from the five sites of the National Institute of Mental Health-sponsored Epidemiologic Catchment Area (ECA) Program, this paper examines the prevalence of psychiatric disorder among recent medical service users versus nonusers, with a particular focus on affective disorders, substance abuse/dependence, and phobias. The rate of current Diagnostic Interview Schedule (DIS) disorders among medical users in all five ECA sites is 21.7 per cent (slightly higher than general population rates) versus 16.7 per cent among nonusers; there is generally no difference between users and nonusers with past DIS diagnoses. Affective disorders were among the most common mental disorders of medical service users, especially among females, with little variation between sites: females: users: 6.9 per cent to 9.3 per cent, nonusers: 3.4 per cent to 6.4 per cent, and males: users: 3.3 per cent to 6.5 per cent, nonusers: 1.2 per cent to 4.1 per cent. Rates of phobias among persons using medical services are also higher than among nonusers. Substance abuse disorders are at least as common among persons who use medical services (8 per cent to 14 per cent of male users) as among those who do not (9 per cent to 11 per cent of male nonusers). The high rates of affective disorders among women and of substance abuse among male medical service users underscore the need to increase the ability of general medical practitioners to recognize and manage or refer these conditions.     

Nutrition and health services needs among the homeless

This review discusses nutrition and related health problems among homeless Americans, summarizes recent information, and identifies needs for services and future research. The nature of homelessness today provides a context for the discussion. Many homeless persons eat fewer meals per day, lack food more often, and are more likely to have inadequate diets and poorer nutritional status than housed U.S. populations. Yet many homeless people eligible for food stamps do not receive them. While public and private agencies provide nutritious food and meals for homeless persons, availability of the services to homeless persons is limited. Many homeless people lack appropriate health care, and certain nutrition-related health problems are prevalent among them. Compared with housed populations, alcoholism, anemia, and growth problems are more common among homeless persons, and pregnancy rates are higher. The risks vary among homeless persons for malnutrition, nutrition-related health problems, drug and alcohol abuse, and mental illness. For example, among homeless persons, fewer heads of families than single adults are substance abusers, and mental illness varies in prevalence among single men, single women, and parents in homeless families. Homeless persons need improved access to food, nutrition, and health services. More nutrition education needs to be available to them and to service providers. Use of representative samples and validation of self-reported nutrition and health data will help future investigators to clarify the relationships between the characteristics of the homeless and their nutritional status.     

Differences in health status,health behaviour and healthcare utilisation between Immigrant and native homeless people in Spain: An exploratory study

Few studies have examined the differences between immigrant and native-born homeless populations. Our aim was to conduct an exploratory study to examine the differences in health status, health behaviour and healthcare utilisation in a sample of Spanish immigrant and native homeless people. Study was conducted in eight different temporary accommodations in the Valencia region in August 2018. Overall, 86 participants were included in the analysis who answered questionnaires concerning socio-demographic characteristics, immigration status, health status and behaviour, healthcare utilisation and experienced discrimination in healthcare and health literacy. In total, 76.7% were men with a mean age of 41.91 (14.17) years, with 60.4% having immigration background with an average of 4.8 (4.2) years since arrival in Spain. No differences were found in the subjective health status, however, native homeless participants reported significantly higher prevalence of heart disease (87.5% vs. 12.5%), hypertension (84.6% vs. 15.4%), psychological illness (63.6% vs. 36.4%) and were also more often smokers (73.5% vs. 28.8%), reported smoking more cigarettes per day (12.0 vs. 7.4) and were more often illegal drug users (17.6% vs. 2.0%). Immigrant participants were significantly more often not insured, reported more problems in healthcare access and had lower rates of visits to general practitioners and less hospital admissions. Differences were also observed in social status with the native homeless more often reporting receiving income, and living in less crowded accommodations. Our results show a variety of issues that the immigrant homeless population in Spain is confronted with that also prevents adequate social inclusion and achieving good health. However, the immigrant population engaged less often in risky health behaviour. More, and continuous, monitoring of social, mental and physical health of the homeless population is necessary. Public health interventions aiming at health promotion in the immigrant homeless populations need to focus on increasing overall social integration.     

Risk factors for homelessness among schizophrenic men: a case-control study.

OBJECTIVES. To identify risk factors for homelessness among the severely mentally ill, we conducted a case-control study of 100 indigent schizophrenic men meeting criteria for literal homelessness and 100 such men with no homeless history. METHODS. Subjects were recruited from shelter, clinic, and inpatient psychiatric programs in Upper Manhattan. Clinical interviewers employed standardized research instruments to probe three domains of risk factors: severity of mental illness, family background, and prior mental health service use. RESULTS. Homeless subjects showed significantly higher levels of positive symptoms, higher rates of a concurrent diagnosis of drug abuse, and higher rates of antisocial personality disorder. Homeless subjects experienced greater disorganization in family settings from birth to 18 years and less adequate current family support. Fewer homeless subjects than subjects in the never-homeless comparison group had a long-term therapist. These differences remained when demographic variables were adjusted statistically. CONCLUSIONS. Homeless schizophrenic men differed from their domiciled counterparts in all three domains we investigated; family background, nature of illness, and service use history. Findings are discussed in relation to policy and programs for the severely mentally ill.     

Surveillance for tuberculosis among residents of hostels for homeless men

Abstract: Tuberculosis has been recognised as an important health problem among homeless persons. The New South Wales tuberculosis screening program for residents of hostels for the homeless has been in operation for several years, but has not yet been evaluated. This study reviewed the performance of the tuberculosis surveillance program (which uses mobile chest x–ray screening) between 1989 and 1993 at the five major hostels for homeless men in the eastern Sydney area. Reports of the screening x–rays and records of subsequent follow–up examinations at chest clinics were examined; information on cases detected by the screening program was compared with notifications in the same population. Of 3555 residents screened during 23 visits, 506 (14.2 per cent) were found to have an abnormal chest x–ray. However, only two active cases of tuberculosis were diagnosed as a result of the screening program, while seven cases were notified on the basis of clinical presentation. About 50 per cent of those with an abnormal chest x–ray from the screening program were lost to follow–up. Possible reasons for loss to follow–up were: long delays in making chest clinic appointments; short–stay residents changing shelters without trace; and high prevalence of severe mental illness or organic brain syndrome among residents. Raising awareness of the disease among primary health care and welfare staff who work with homeless men may be a more effective approach to improving identification of cases of active tuberculosis in this population.

Needs of homeless people coping with psychiatric problems: findings from an innovative advocacy project

In this article the authors report on the self-perceived needs of 40 homeless people who are coping with psychiatric problems. These people were among 207 with psychiatric problems participating in an innovative advocacy project based outside the formal mental health system. Compared with domiciled participants, the homeless participants had more accentuated and somewhat different major daily living needs in the areas of income and benefits, housing, legal services, employment, and health care. On the basis of these findings, the authors draw implications for social work practice with homeless people coping with psychiatric problems.     

Urban homelessness and poverty during economic prosperity and welfare reform: Changes in self-reported comorbidities,insurance, and sources for usual care, 1995–1997

Little is known of how homeless and other urban poor populations have fared during the robust economy and within structural changes in health care delivery and entitlement programs of the 1990s. This is important in determining the need for population-specific services during a vigorous economy with low unemployment and increasing Medicaid managed-care penetration. This study compared health insurance status and availability of a source for usual medical care, psychiatric and substance abuse comorbidities, and perceived causes of homelessness in homeless adults surveyed in 1995 and 1997. Cross-sectional, community-based surveys were conducted in 1995 and 1997 at sites frequented by urban homeless adults residing in Pittsburgh, Pennsylvania. Self-reported medical, mental health, and substance abuse comorbidities, health insurance, and source for usual care were measured. Compared to the 388 individuals surveyed in 1995, the 267 homeless adults surveyed in 1997 had more medical comorbidity (56.6% vs. 30.2%, P<.001) and mental health comorbidity (44.9% vs. 36.9%, P=.04) and required more chronic medication (52.1% vs. 30.3%, P<.001). More respondents in 1997 than 1995 reported having no health insurance (41.4% vs. 29.4%, P<.001). While there was no difference in the overall proportion reporting a source for usual care (78.3% in 1997 vs. 80.2% in 1995, P=.55), fewer persons reported use of the emergency department and more persons reported using a shelter-based clinic for usual care in 1997 compared with 1995. These findings suggest more need for medical care among homeless and urban poor persons in 1997 compared with 1995 and support the continued need for outreach and support services despite a vigorous economy.     

The prevalence and health impact of shiftwork.

Data from the National Center for Health Statistics National Survey of Personal Health Practices and Consequences were analyzed to determine the impact of variable shift schedules on health-related behaviors of persons in the United States labor force. Twenty-six per cent of men and 18 per cent of women in the US labor force reported working a variable shift in Spring 1980. As compared to men working non-variable work schedules, those working variable shifts exhibited higher rates of heavy drinking, job stress, and emotional problems. Female variable shift workers reported higher rates of sleeping pill, tranquilizer, and alcohol use, as well as lower social network scores, more job stress, and more emotional problems.     

Where do people go when they first become homeless? A survey of homeless adults in the USA

The longer a person is homeless, the more likely he or she is to experience poor health and be placed at higher risk for premature death. This makes interventions early in one's homelessness an important prevention strategy. However, little is known about where someone goes for help when they first become homeless and how well those sites are prepared to address the multitude of issues facing a homeless person. In order to address this question, we conducted a cross-sectional community-based survey in two US cities in 1997 using population proportionate sampling of homeless persons identified at 91 sites to identify 'first-stop' access sites and reasons for seeking help at those sites. A total of 230 persons participated in the face-to-face interview (93% response rate). From a list of 20 possible 'first-stop' sites, 105 (45.7%) reported going to a soup kitchen, 71 (30.9%) went to a welfare office, 64 (27.8%) sought admission to a detoxification centre, 60 (26.1%) met with a homeless outreach team, 57 (24.8%) went to a family member, and 54 (23.5%) went to an emergency room. Individuals with a chronic medical or mental health condition were significantly more likely to access a healthcare site (medical: 62.6% vs. 47.6%, P = 0.02; mental health: 62.4% vs. 38.8%, P < 0.01) or social service agency (medical: 64.0% vs. 43.3%, P = 0.02; mental health: 59.1% vs. 40.7%, P < 0.01). Those persons reporting a need for alcohol treatment were significantly more likely to first go to a healthcare site (46.4% vs. 29.1%, P < 0.01) and those with alcohol abuse/dependence were less likely to seek help from family or friends (66.7% vs. 81.9%, P < 0.01). Most respondents sought assistance for concerns directly associated with an immediate need as opposed to seeking care for issues causing their actual homelessness. These findings suggest the need to expand and integrate the availability of services at 'first-stop' access sites that facilitate early exits from homelessness.     

Overrepresentation of women veterans among homeless women

OBJECTIVES: This study estimated the proportion of veterans among homeless women and their risk of homelessness relative to that of nonveterans. METHODS: Data came from 2 surveys of homeless women (1 clinical and 1 nonclinical) and 1 survey of domiciled women. RESULTS: The proportion of veterans (4.4%, 3.1%) among homeless women was greater than the proportion among domiciled women (1.3%, 1.2%). When we computed odds ratios for being a veteran among homeless women compared with nonhomeless women, homeless women were significantly more likely than nonhomeless women to be veterans. CONCLUSIONS: Women veterans are at greater risk for homelessness than are nonveterans. Further study is needed to determine whether increased risks for veterans are a product of military service or reflect volunteers' self-selection into the armed forces.     

Perceived health status among the new urban homeless

Homelessness may be the leading social problem in the United States in the mid 1980s. While there may be anywhere from 250,000 to three million homeless persons, few empirically based published studies are available concerning the correlates of mental and physical health status among the homeless. Los Angeles, where the present study was conducted, has been designated by the U.S. Department of Housing and Urban Development to have one of the largest homeless populations (34,000-50,000) in the U.S. The current study is based on 269 in-depth interviews with homeless men and women in Los Angeles County, California. The homeless were found to be younger, better educated and disproportionately non-white compared to the profiles of the skidrow homeless of the past decades. Nearly half the men were veterans of military services, including 30% who were veterans of the Vietnam War. Respiratory infections and hypertension were the most prevalent health problems. The data suggest that a large segment of the homeless persons were depressed, 15.6% reported lifetime prevalence of hospitalization for emotional or nervous problems, and 12.6% reported hospitalization for substance abuse disorders. Multiple regression was utilized to test the validity of a perceived health status index as measured among the homeless and to identify the correlates of health. The health index reflect primarily an affliction by a chronic disease, the severity of an acute condition, the duration of depressed mood, and the alcoholism symptomatology. Length of unemployment, education, gender, and number of nights spent in a shelter were the best predictors of poor health in this population. Evidence from this study, as well as others, suggests that efforts should be made to avoid using the term homeless metaphorically. The causes of homelessness are multiple and complex and the resulting subgroups among the homeless population have different problems which require a variety of strategies to meet their needs.     

Gender Differences and Risk of Arrest Among Offenders with Serious Mental Illness

Despite the increasing number of men and women with serious mental illness (SMI) incarcerated in America's jails, little research exists on the role gender may play in arrest among persons with SMI. This study examined correlates of arrests among offenders with SMI, specifically the role of gender. County criminal justice records, as well as county and statewide social service archival databases, were used to identify jail inmates with SMI in a large urban county in Florida. Of the 3,769 inmates identified, 41% were female. This study identified three distinct classes of male and female offenders within which persons had similar trajectories of arrests over the 4-year study period representing those with minimal, low, and high arrest rates. Findings suggest some important differences between women and men in risk factors for re-arrests. Attention to these factors may improve the ability to prevent future recidivism among men and women with SMI.     

Emergency department use among the homeless and marginally housed: results from a community-based study

OBJECTIVES: This study examined factors associated with emergency department use among homeless and marginally housed persons. METHODS: Interviews were conducted with 2578 homeless and marginally housed persons, and factors associated with different patterns of emergency department use were assessed in multivariate models. RESULTS: Findings showed that 40.4% of respondents had 1 or more emergency department encounters in the previous year; 7.9% exhibited high rates of use (more than 3 visits) and accounted for 54.5% of all visits. Factors associated with high use rates included less stable housing, victimization, arrests, physical and mental illness, and substance abuse. Predisposing and need factors appeared to drive emergency department use. CONCLUSIONS: Efforts to reduce emergency department use among the homeless should be targeted toward addressing underlying risk factors among those exhibiting high rates of use.     

Diet and other life-style factors in high and low socio-economic groups (Dutch Nutrition Surveillance System)

Insight into the occurrence of and the association between certain socio-economic variables and life-style characteristics is necessary for preventive nutrition and health policy. The prevalence of and the interdependencies among these variables were examined in 1930 men and 2204 women aged 19 to 85 who participated in the Dutch National Food Consumption Survey 1987-1988. Dietary data were based on a two-day record. The associations among discrete variables were analysed using log-linear models. Analysis of covariance was used to explore the effects of the aggregate socio-economic status (SES) on dietary intake and anthropometry, whereas differences in food intake and SES were assessed by the non-parametric test of Kruskal and Wallis. In comparison to subjects with a high SES in people with a low SES a higher proportion of smokers (48 vs 32 per cent) was observed, a higher prevalence of obesity (39 vs 28 per cent), a higher percentage of heavy coffee drinkers (greater than six cups per day, 23 vs 17 per cent), and more subjects who skipped breakfast (19 vs 11 per cent). In the highest SES class more subjects used nutritional supplements (18 vs 11 per cent), more subjects followed a dietary rule (five vs two per cent), such as a vegetarian diet, and a higher proportion used more than three alcoholic drinks per day (19 vs 15 per cent). A higher SES was associated with a lower fat intake, but the differences (expressed as per cent of energy intake) were rather small and even absent among women when the contribution of alcohol to energy was not taken into account. In general, dietary intake among subjects in higher SES groups tended to be closer to dietary recommendations. The results indicate that a lower SES is accompanied by a higher prevalence of several indicators of an unhealthy life-style.     

A population-based assessment of the health of homeless families in New York City, 2001-2003

Objectives. We compared estimated population-based health outcomes for New York City (NYC) homeless families with NYC residents overall and in low-income neighborhoods.Methods. We matched a NYC family shelter user registry to mortality, tuberculosis, HIV/AIDS, and blood lead test registries maintained by the NYC Department of Health and Mental Hygiene (2001–2003).Results. Overall adult age-adjusted death rates were similar among the 3 populations. HIV/AIDS and substance-use deaths were 3 and 5 times higher for homeless adults than for the general population; only substance-use deaths were higher than for low-income adults. Children who experienced homelessness appeared to be at an elevated risk of mortality (41.3 vs 22.5 per 100 000; P < .05). Seven in 10 adult and child deaths occurred outside shelter. Adult HIV/AIDS diagnosis rates were more than twice citywide rates but comparable with low-income rates, whereas tuberculosis rates were 3 times higher than in both populations. Homeless children had lower blood lead testing rates and a higher proportion of lead levels over 10 micrograms per deciliter than did both comparison populations.Conclusions. Morbidity and mortality levels were comparable between homeless and low-income adults; homeless children''s slightly higher risk on some measures possibly reflects the impact of poverty and poor-quality, unstable housing.Most studies examining the health of homeless populations have involved single adults and have identified higher rates of death, tuberculosis (TB), HIV/AIDS, mental health disorders, substance use, poor birth outcomes, and cardiovascular disease than in the general population.^1–7 Whether these findings can be generalized to homeless families is not known, as the 2 populations differ greatly. Nationally, homeless families overwhelmingly consist of a young female head of household with children, whereas single homeless adults are mostly men aged 31 to 50 years.⁸ Homeless families are also distinct in their reasons for becoming homeless, citing poverty more often and substance use and mental illness less often than is the case for their single adult counterparts.⁹ Based on their demographic and socioeconomic profiles, the health of homeless families may be more like that of other low-income families than that of homeless single adults.Recent economic conditions have led to a rise in the number of homeless families nationwide. Although overall US homelessness held fairly constant from 2007 to 2008, the number of homeless families increased by 9%. According to the latest available national data, an estimated 516 700 adults and children were sheltered as families over a 1-year period in 2008, constituting roughly a third of the overall sheltered homeless population during that time.⁸ More recent data from a sampling of localities found that, as of September 2009, the count of sheltered families had increased 10% from the previous quarter, as foreclosure and unemployment rates continued to rise.¹⁰In New York City (NYC), the Department of Homeless Services (DHS) supplies apartment-style shelters and support services such as childcare, housing assistance, and health care referral to homeless families. Because the city provides emergency shelter to eligible families, virtually all homeless families use shelter facilities. In 7 years of an annual count of street homeless, a family has never been found on the street.¹¹ A small share of homeless families is sheltered by city agencies other than DHS. However, analyses based on DHS shelter registry likely include the vast majority of the NYC homeless family population.Our objective was to systematically characterize the health of adults and children who used the NYC family shelter system. We matched the DHS family shelter registry with 4 health registries managed by the NYC Department of Health and Mental Hygiene, and we compared estimates of morbidity and mortality in the homeless family population with those of the NYC general and lowest-income neighborhood populations.     

Health status and access to health services among the urban homeless.

Self-reported health status and access to care were reported for 238 homeless adults in Los Angeles. One-third reported their health as fair or poor; women reported more health problems than men. Half (53 per cent) of the sample reported no regular source of care, and most (81 per cent) were without health insurance. Lack of financial resources and health insurance were reported as important barriers to care.     

Use of psychiatric services by homeless veterans

Patients treated in a Department of Veterans Affairs (VA) emergency room were evaluated to delineate the differences in use of services between homeless and domiciled veterans who have mental disorders. Data were obtained and compared on DSM-III-R diagnoses, number of hospitalizations, lengths of stay, and outpatient visits in the preceding year. Homeless veterans with mental disorders were significantly more likely to have emergency visits and psychiatric admissions in the preceding 12 months than were the domiciled veterans. However, the average length of stay was shorter for the homeless group. These differences must be accounted for in the design of programs targeting homeless veterans with mental illness. Earlier versions of this article were presented at the International Congress on Emergency Psychiatry, October 1993, in Quebec, and at the annual meeting of the American Psychiatric Association, May 1994, in Philadelphia. This work was partially supported by a Health Services Research and Development grant from the Department of Veterans Affairs.     

The Reality of Homeless Mobility and Implications for Improving Care

Homeless persons are perceived as a highly mobile population, and have high rates of co-morbid conditions, including mental health and substance use issues. This study sought to determine the characteristics of the mobility and reported health conditions of homeless persons. The sample for this cross sectional study (n = 674) accounted for 88 % of the homeless population in a medium sized southern city in the United States. Participants were recruited from a homeless shelter operating during the winter season. Homeless persons were less mobile than the general state population (46.11 % were born in-state vs. 40.7 % of the general population) and less transient than the general state population (78 % reported an in-state zip code for the last permanent residence). 31.9 % reported a disabling condition of a serious and long term nature. These findings challenge the concept that homeless persons are primarily a mobile population. Furthermore, homeless persons in this sample were more likely to remain in the state where they lived after becoming homeless. Thus, provider perceptions that homeless persons would not benefit from referral to a regular source of outpatient care may be misinformed. As homeless persons often seek care in emergency departments for conditions that could be addressed through outpatient care, if a medical care system implemented standard practices specifically for homeless patients, this could decrease recidivism. Such interventions represent significant opportunities to reduce costs, conserve resources, and improve care through policy modification that ensures a focus on a successful, active linkage to outpatient care and programs specific to the homeless population.     

Gender, social relations and mental health: prospective findings from an occupational cohort (Whitehall II study)

Gender differences in social support tend to suggest that women have larger social networks and both give and receive more support than men. Nevertheless, although social support has been identified as protective of mental health, women have higher rates of psychological distress than men. We examine the prospective association between social support and psychological distress by gender in a cohort study of middle aged British Civil Servants, the Whitehall II study. In this sample we found that women have a larger number of close persons than men although men have larger social networks. We also found that the effects of marital status, social support within and outside the workplace and social networks on subsequent occurrence of psychological distress were similar for men and women independently of baseline mental health status.     

Responding to the needs of the homeless mentally ill

The homeless mentally ill represent a pivotal and urgent challenge to the mental health field in the 1980s. Those homeless who have extended histories of psychiatric hospitalization stand as harsh reminders of the failures of deinstitutionalization, while young mentally ill homeless adults who never have been treated as inpatients testify to the gaps and unrealized promises of community-based care under deinstitutionalization. Homelessness and mental illness are social and clinical problems, respectively, distinct in some ways but intertwined in others. Some of the factors that contribute to homelessness--such as economic deprivations, a dearth of low-cost housing, discontinuities in social service systems, and radical changes in the composition of American families--are felt particularly keenly by many persons who are mentally ill. And symptoms of mental disorders, in turn, frequently impede an individual's capacities to cope with those, as well as other, stressors. Developing appropriate and effective responses to the needs of homeless people who are mentally ill requires precise definition and identification of the target population, innovations in the mental health service system, encouragement of those who staff it to work with homeless mentally ill patients, and public education. Ultimately, however, fundamental answers will be found in an improved understanding of severe mental illness, enhanced treatment capacities, and greater attention to the rehabilitative needs of mentally ill persons.
