High prevalence rates of diabetes and hypertension among refugee psychiatric patients

There is increasing evidence that immigrants and traumatized individuals have elevated prevalence of medical disease. This study focuses on 459 Vietnamese, Cambodian, Somali, and Bosnian refugee psychiatric patients to determine the prevalence of hypertension and diabetes. The prevalence of hypertension was 42% and of diabetes was 15.5%. This was significantly higher than the US norms, especially in the groups younger than 65. Diabetes and hypertension were higher in the high-trauma versus low-trauma groups. However, in the subsample with body mass index (BMI) measurements subjected to logistic regression, only BMI was related to diabetes, and BMI and age were related to hypertension. Immigrant status, presence of psychiatric disorder, history of psychological trauma, and obesity probably all contributed to the high prevalence rate. With 2.5 million refugees in the country, there is a strong public health concern for cardiovascular disease in this group.

Psychiatric epidemiology of an Indian village : a 19-year replication study

This 1988 study reports the point and lifetime prevalence of psychiatric disorders, using DSM-III-R criteria, of a sample (approximately 25%) of adult members of an Indian village previously studied in 1969. The basic instrument was the Schedule for Affective Disorders and Schizophrenia, augmented by available medical information and administered by experienced psychiatrists. Subjects were interviewed and results were weighed for the age- and sexdistributed population. The results indicated a high point prevalence of alcohol dependence (32.8%), with a lifetime prevalence of 72.8%, among males. The lifetime prevalence of affective disorders among women was also high (36.8%), but less so among men (19.3%). When compared with the DSM-III-R diagnoses of the 1969 study, the point prevalence rates of alcohol dependence and abuse disorders fell from 39% to 21%. Also, fewer subjects were judged to be psychiatrically impaired. Even though the prevalence of psychiatric disorders was lower in the current study, the rates for alcohol disorders and affective disorders were still far higher than those reported in Epidemiologic Catchment Area studies. Alcohol dependence (especially among young men) and affective disorder (among women) were major problems.

Criterion validity of the center for epidemiologic studies depression scale in a population sample from an American Indian village

The criterion validity of the Center for Epidemiologic Studies Depression Scale (CES-D) is examined in 120 adult Northwest Coast American Indians. The criterion was a DSM-III-R diagnosis derived from the Lifetime version of the Schedule for Affective Disorders and Schizophrenia. Sensitivity for major depression was 100% (95% confidence limits 36%, 100%); specificity was 82.1% (75.1%; 89%). For a broad category of depressive disorders (n = 9), sensitivity was 77.8% and specificity was 84.7%. Cut points based on receiver operating characteristic analyses did not greatly improve the performance of the CES-D. The use of factor scores instead of total scores made little difference.

Use of the CES-D in an American Indian village

In this paper, we examine the performance of a pencil-and-paper screening questionnaire on depressive symptoms (the Center for Epidemiologic Studies Depression Scale, or CES-D) in a sample of 120 adult American Indians belonging to a single Northwest Coast tribe. Results of factor analyses suggest that somatic complaints and emotional distress are not well differentiated from each other in this population. CES-D scores (which have shown good sensitivity and specifity for depressive disorders in this sample) also show weak and apparently nonsignificant trends to be elevated in the presence of other psychiatric diagnoses (including alcoholism) or general impairment. However, because of the use of a convenience sample (rather than a probability sample), analyses of associations between study factors - including comorbidity - are liable to produce spurious results due to selection bias (including Berkson bias). On this basis, we suggest that the use of probability samples should assume a high priority in cross-cultural studies. The study of the entire population of interest is another solution to the sampling problem, particularly in small communities.

Group therapy with Southeast Asian refugees

This report describes a one-year experience with a new program of group therapy for Southeast Asians who were treated in a psychiatric program for Indochinese refugees. Cultural factors involving communication styles, respect for authority, and traditional social relationships greatly influence the group process. Socialization experiences which encouraged traditional activities and practical information were the most acceptable medium by all the groups. Psychological issues of losses, cultural conflicts, and persistent discussion of somatic symptoms were voiced throughout the activities. Formal group psychotherapy was periodically useful in some groups. Flexibility, meeting concrete needs, keeping a bicultural focus, and maintaining the individual therapy sessions contributed to the acceptance by the patient.

Cross-cultural psychiatric residency training: the Oregon experience.

ObjectiveThe purpose of this article is to describe the goals and structure of cross-cultural psychiatric training at Oregon Health and Science University (OHSU). This training in core knowledge, skills, and attitudes of cultural psychiatry over the past three decades has included medical students, residents, and fellows, along with allied mental health personnel. The curriculum includes both didactic sessions devoted to core topics in the field and varied clinical experiences in community settings and the Intercultural Psychiatric Program under the supervision of experienced academic faculty.MethodsThe authors review the central elements of the training experiences and include a detailed description of the core clinical settings and experiences.ResultsAt the conclusion of their clinical experiences, trainees have specialized cross-cultural psychiatric knowledge and skills, including treatment of refugees and immigrants, sociocultural variables that influence the assessment and treatment of a wide range of psychiatric conditions, and comfort with cultural dynamics that influence both the doctor/patient relationship and collaboration with a wide range of mental health professionals.ConclusionBecause of rapid demographic changes in the U.S. population, providing cross-cultural training for students, residents, and fellows is an essential foundation for the education of the next generation of clinicians and health care leaders. OHSU has provided a long-term model for this training in a busy clinical and academic setting that places an emphasis on multi-disciplinary and multicultural collaboration.

The natural history of medical and psychiatric disorders in an American Indian community

In 1969, a Pacific Northwest American Indian community cohort (n=100) was interviewed for the presence of physical and psychiatric illnesses. The same community was studied again in 1988. This study describes the outcome among the original 100 subjects. The schedule for Affective Disorders and Schizophrenia Lifetime Version (SADS-L) served as the basic interview instrument, supplemented by data from medical records, death certificates, and medical and community informants. Twenty-five subjects had died, 13 from cardiovascular disorders and seven from alcohol-related illnesses. Among the 46 subjects re-interviewed, hypertension, heart disease, and diabetes had become significant sources of medical morbidity. Alcoholism was the most significant cause of psychiatric morbidity, particularly among males. This study indicates that greater attention should be focused upon prevention and treatment of alcoholism, cardiovascular disorders, and diabetes in this community and in other American Indian populations.

The Intercultural Psychiatric Program at Oregon Health and Science University

The Intercultural Psychiatric Program at Oregon Health and Science University, founded in 1978, is a community-based clinic that serves refugees and immigrants from around the world. Besides its clinical mission, the program also trains medical and mental health professionals in numerous aspects of cross-cultural mental health care and has made substantial contributions to the refugee and immigrant mental health literature. This narrative reviews the history of the program, discusses its clinical model and its education mission, and highlights its most significant research contributions. In addition, financial and management challenges are discussed in the context of almost four decades of successful operation.
