Cultural epidemiology: An introduction and overview

Socio-cultural determinants of anticipated acceptance of an oral cholera vaccine in Western Kenya

Determinants of anticipated acceptance of an oral cholera vaccine (OCV) were studied in urban and rural communities of Western Kenya. An explanatory model interview administered to 379 community residents assessed anticipated vaccine acceptance at various prices from no cost to full-cost recovery, socio-cultural features of cholera and social characteristics. Nearly all (99%) residents indicated willingness to accept a no-cost OCV, 95% at a price of US$ 0·8, 73% at US$ 4·2 and 59% at US$ 8·4. Logistic regression models analysed socio-cultural determinants of anticipated OCV acceptance. Prominence of non-specific symptoms for cholera was negatively associated with acceptance. A cholera-specific symptom (thirst), self-help referring to prayer, income and education were positively associated. In the high-cost model, education was no longer significant and reliance on herbal treatment was a significant determinant of vaccine non-acceptance. Findings suggest high motivation for OCVs, if affordable. Socio-cultural determinants are better predictors of anticipated acceptance than socio-demographic factors alone.

Drug use opportunities as opportunities for drug use prevention: Bogotá, Colombia a case in point

BACKGROUND

As drugs become more ubiquitous and fewer resources are available for drug prevention and treatment, understanding the early stages of drug use involvement becomes increasingly important for prevention efforts. This study aims to explore the concept of drug use opportunity, and to disentangle, from a socio-ecological perspective, the factors associated with experiencing a drug use opportunity.

METHODS

Data from 2279 standardized questionnaires administered in 23 schools in Bogotá was analyzed. Schools were selected in a multistage probability cluster sample. Multilevel logistic regression modeling estimated the effects of multiple level factors on the likelihood of having experienced an opportunity to use illicit drugs or inhalants.

RESULTS

One-third of respondents (32.1%) reported having had an opportunity to use drugs. Even among those who perceived drugs to be readily available and/or expressed intentions to use drugs in the near future, most reported never having experienced an opportunity to use drugs. For most of the drugs assessed, peer drug use, cigarette smoking, alcohol drinking, problematic behavior, and degree of school safety were the strongest correlates of having had a drug use opportunity.

CONCLUSIONS

Despite living in an environment of high drug availability, most adolescents do not experience opportunities to use drugs. The likelihood of experiencing an opportunity is influenced by multiple interacting individual and macro-social factors, just as drug use is. Drug use opportunities were mainly promoted by friends, suggesting the need to consider their role within close social networks, alongside that of drug suppliers, in the design of intervention activities and drug policy development.

Impact of migration on explanatory models of illness and addiction severity in patients with drug dependence in a Paris suburb

Objectives of this study were to assess explanatory models (considering illness experience and meaning), addiction severity among patients with drug dependence, and the role of migration. Adapted Explanatory Model Interview Catalogue interviews were conducted with 70 outpatients in a Paris suburb. Among them, 42 were either first- or second-generation immigrants, most from North Africa. Explanatory models were analyzed qualitatively and quantitatively according to migration status, assessing potential confounders with multivariate linear models. Explanatory models were heterogeneous. Compared with nonmigrants, migrants reported fewer somatic and violence-related symptoms. They attributed the causes of their addiction more frequently to social and magico-religious factors and less to psychological factors. Conversely, no difference in addiction severity was found between migrants and nonmigrants. Considering local patterns of illness experience and meaning of drug dependence is a critical component of culturally sensitive clinical care.

Social and cultural determinants of anticipated acceptance of an oral cholera vaccine prior to a mass vaccination campaign in Zanzibar

Despite improvements in sanitation and water supply, cholera remains a serious public health burden. Vaccination is included among recommendations for cholera control. Cultural concepts of illness are likely to affect vaccine acceptance. This study examined social and cultural determinants of anticipated acceptance of an oral cholera vaccine (OCV) prior to a mass vaccination campaign in Zanzibar. Using a cultural epidemiological approach, 356 unaffected adult residents were studied with vignette-based semi-structured interviews. Anticipated acceptance was high for a free OCV (94%), but declined with increasing price. Logistic regression models examined social and cultural determinants of anticipated acceptance at low (USD 0.9), medium (USD 4.5) and high (USD 9) price. Models including somatic symptoms (low and high price), social impact (low and medium) and perceived causes (medium and high) explained anticipated OCV acceptance better than models containing only socio-demographic characteristics. Identifying thirst with cholera was positively associated with anticipated acceptance of the low-priced OCV, but acknowledging the value of home-based rehydration was negatively associated. Concern about spreading the infection to others was positively associated at low price among rural respondents. Confidence in the health system response to cholera outbreaks was negatively associated at medium price among peri-urban respondents. Identifying witchcraft as cause of cholera was negatively associated at medium and high price. Anticipated acceptance of free OCVs is nearly universal in cholera-endemic areas of Zanzibar; pre-intervention assessments of community demand for OCV should not only consider the social epidemiology, but also examine local socio-cultural features of cholera-like illness that explain vaccine acceptance.

Cultural epidemiology of neurasthenia spectrum disorders in four general hospital outpatient clinics of urban Pune, India

Disorders emphasizing symptoms of fatigue and/or weakness, collectively termed Neurasthenia Spectrum Disorders (NSDs), typically emphasize a biological basis in the West and social origins in East Asia. In India, explanatory concepts are diverse. To clarify, 352 outpatients in Psychiatry, Medicine, Dermatology, and Ayurved clinics of an urban hospital were interviewed with a version of the Explanatory Model Interview Catalogue. Comparisons of categories and narratives of illness experience and meaning across clinics indicated both shared and distinctive features. Explanatory models of NSDs highlighted social distress, ''tensions,'' and both general and clinic-specific physical, psychological, and cultural ideas. Findings indicate the importance of social contexts and cultural meaning in explanatory models of neurasthenia, as well as the potential clinical relevance of the construct of Neurasthenia Spectrum Disorder.

Developing a function impairment measure for children affected by political violence: a mixed methods approach in Indonesia

OBJECTIVE

Practitioners in political violence-affected settings would benefit from rating scales that assess child function impairment in a reliable and valid manner when designing and evaluating interventions. We developed a procedure to construct child function impairment rating scales using resources available in low- and middle-income countries.

DESIGN

We applied a mixed methods approach. First, rapid ethnographic methods (brief participant observation, collection of diaries and a focus group with children) were used to select daily activities that best represented children's functioning. Second, rating scales based on these activities were examined for their psychometric properties. Construct validity was assessed through a confirmatory factor analysis procedure.

SETTING

Central Sulawesi, Indonesia.

PARTICIPANTS

Qualitative data were collected for 53 children and psychometric testing was done with 403 children [average age: 9.9 (SD = 1.21), 49% girls] and 385 parents.

RESULTS

Using locally available resources, we developed separate child-rated and parent-rated scales, both containing 11 items. The child-rated scale evidenced good internal, test-retest and inter-rater reliability and acceptable convergent and discriminant validity. Construct validity was confirmed by fit of the theorized factor structure-a social-ecological clustering of daily activities.

CONCLUSIONS

The procedure resulted in a reliable and valid rating scale to assess child function impairment in the context of political violence. Practitioners can apply this procedure to develop new locally adequate rating scales to strengthen epidemiological surveys, baseline assessments, monitoring and evaluation and eventually, interventions. Further research should address the importance of gender differences and criterion-related validity.

Mental illness stigma and ethnocultural beliefs, values, and norms: an integrative review

The current literature on the problem of mental illness stigma in the United States must be expanded to better account for the role of culture. This article examines the relationship between mental illness stigma and culture for Americans of American Indian, Asian, African, Latino, Middle Eastern, and European descent. In this review, culture refers to the shared beliefs, values, and norms of a given racial or ethnic group. The reviewed literature indicates that there are differences in stigma among the various cultural groups; however, explanations as to why these differences exist are scant. Qualitative and quantitative studies indicate that cultural values are important with regard to stigma, particularly for Asian Americans and African Americans. Less is known about the interaction between cultural values and mental illness stigma for other cultural groups. Continued research in the area requires better organization and more exploration of the role of cultural history and values as they relate to mental illness stigma. To that end, a detailed, systematic approach to future research in the area is proposed.

Explaining socio-economic inequalities in daily smoking: a social-ecological approach

BACKGROUND

This study assessed the contributions of individual, household and neighbourhood-level factors to socio-economic inequalities in smoking.

METHODS

Data came from 2706 participants of the 2004 wave of the Dutch GLOBE study. Participants were asked about several social and material characteristics of their households, neighbourhoods and smoking in their environment. Indicators of socio-economic position were education and income. Associations with daily smoking were examined using logistic regression analyses.

RESULTS

Education and income were independently associated with daily smoking (mutually adjusted odds ratios for the lowest education and income groups: odds ratio (OR): 2.87, 95% confidence interval (95% CI): 1.78-4.62; OR: 1.55, 95% CI: 1.09-2.23, respectively). Individual beliefs about smoking contributed most to the association of education with daily smoking. Individual beliefs about smoking and household material adversity contributed most to the association of income with daily smoking. We found no evidence that negative perceptions of the neighbourhood contributed to smoking inequalities. In fully adjusted models, associations between income and smoking were fully attenuated, but an independent association between education and smoking remained.

CONCLUSION

Education and income were related to smoking through partly different pathways. Reducing inequalities in smoking may require a multidimensional approach targeting material and social factors, with strategies targeted towards the individual and the household level.

Current clinical advances and future perspectives in the psychiatry/mental health field of Latin America

The history of Mental Health in Latin America is relatively young. It dates back to the mid nineteenth century and widely developed during the twentieth century, with formidable scientific, social, political, and ethical challenges. Latin American psychiatry has contributed in the fields of epidemiology, phenomenology, social psychiatry, psychiatric and epistemological research, and clinical genetics as well. More recent advances can also be seen in clinical psychotherapy and psychopharmacology. Now, there is a formal and informal recognition of various areas of expertise, such as children and adolescents, addictions, anxiety disorders, among others. However, we need to solve the health problems resulting from mental illnesses as well as the disorders related to the social, environmental, political, and economic factors of a continent marked by the precariousness of underdevelopment, which have a high impact on population health. Therefore, considering and trying to minimize the impact of those factors, contributing to the destigmatization of mental illnesses and their consequences, together with the growing number of non-governmental organizations (NGOs), human rights defenders, public figures, etc., and collaborating in building a society that guarantees the right to mental health and adequate treatment and rehabilitation are part of our present challenges in Latin America.

Culture and Psychopathology: Foundations, Issues, Directions

The present article offers an overview of the historical influences, conceptual assumptions, and major findings and issues associated with the study of culture and psychopathology. The article traces continuing reductionistic resistance to the incorporation of cultural considerations in the etiology, expression, and treatment of psychopathology to historical and contemporary forces. These forces include ‘cultural context’ of Western psychiatry and psychology, which choose to locate the determinants of behaviour in the human mind and brain. A definition of culture that acknowledges its internal and external representations is offered, and steps in the cultural construction of reality are proposed. Within this context, the risks of imposing Western cultural views universally are noted, especially attempts to homogenise classification and diagnostic systems across cultures. ‘Culture-bound’ disorders are used as example of Western bias via the assumption that they have ‘real’ disorders, while the other cultures have disorders that are shaped by culture. Cultural considerations in understanding the rate, etiology, and expression are presented, including recommended criteria for conducting epidemiological studies across cultural boundaries, especially ‘schizophrenic’ disorders as this problematic diagnostic category is subject to multiple cultural variations. The article closes with discussions of ‘cultural competence’ and ‘multilevel’ approaches to behaviour.

Social and cultural features of cholera and shigellosis in peri-urban and rural communities of Zanzibar

Background

Responding to the high burden of cholera in developing countries, the WHO now considers vaccination as a supplement to the provision of safe drinking water and improved sanitation in the strategy for cholera control in endemic settings. Cultural concepts of illness affect many aspects of public health. In the first step of a two-step strategy to examine determinants of cholera vaccine acceptance, this study identified social and cultural features of diarrhoeal illness for cholera control in endemic communities.

Methods

A cultural epidemiological study with locally adapted vignette-based interviews was conducted in two cholera-endemic communities of Zanzibar. A random sample of unaffected peri-urban (n = 179) and rural (n = 177) adults was interviewed to study community ideas of cholera and shigellosis, considering categories of distress, perceived causes, and help-seeking behaviour.

Results

Cholera was recognised by 88%. Symptoms of dehydration were most prominent in reports at the peri-urban site. Interference with work leading to strain on household finances was frequently emphasised. Dirty environment was the most prominent perceived cause, followed by unsafe drinking water and germ-carrying flies. Causes unrelated to the biomedical basis of cholera were reported more often by rural respondents. Rural women had more difficulty (20%) to identify a cause than men (7.1%, p = 0.016). Peri-urban self treatment emphasised rehydration; the rural community preferred herbal treatment and antibiotics. Shigellosis was recognised by 70%. Fewer regarded it as very serious compared with cholera (76% vs. 97%, p < 0.001) and regarded it as less likely to be fatal (48% vs. 78%, p < 0.001). More respondents could not explain causes of shigellosis (23%) compared with cholera (7.3%, p < 0.001). Community respondents less frequently identified dehydration and contagiousness for shigellosis. Government facilities were preferred healthcare providers for both conditions.

Conclusions

This study clarified local views of cholera and shigellosis relevant for diarrhoeal disease control in Zanzibar. The finding that rural women were less likely than men to specify causes of cholera suggests more attention to them is required. Better health education is needed for cholera in rural areas and for shigellosis in general. This study also identified variables for subsequent analysis of social and cultural determinants of cholera vaccine acceptance.

Structural forces and the production of TB-related stigma among Haitians in two contexts

In recent years renewed interest in health-related stigma has underscored the importance of better understanding the structural underpinnings of stigma processes. This study investigated the influence of sociocultural context on perceived components of tuberculosis-related stigma in non-affected persons by comparing Haitians living in South Florida, USA, with Haitians residing in Léogane Commune, Haiti. Using the methods of cultural epidemiology, a two-phase study based on fieldwork between 2004 and 2007 collected ethnographic data on the cultural context and components of tuberculosis (TB) stigma, and administered a stigma scale developed specifically for these populations. Thematic analysis of stigma components expressed in interviews, focus groups and observation revealed commonalities as well as distinctive emphases of TB stigma in the two comparison groups. Factor analyses of stigma scale scores confirmed the thematic differences revealed in ethnographic findings and highlight the influence of political and economic factors in shaping the meaning and experience of illness. Perceived components of TB stigma among Haitians in South Florida incorporated aspects of Haitian identity as a negatively stereotyped minority community within the larger society, while in Haiti, stigma was associated primarily with poverty, malnutrition, and HIV co-infection. Discussion of findings focuses on the social production of perceived and anticipated stigma as it is influenced by structural forces including the influences of politics, economics, institutional policies, and health service delivery structures. The findings also demonstrate the value of a transnational framework encompassing both sending and receiving countries for understanding TB-related stigma in immigrant communities.

Culture, cultural factors and psychiatric diagnosis: review and projections

This paper aims to provide conceptual justifications for the inclusion of culture and cultural factors in psychiatric diagnosis, and logistic suggestions as to the content and use of this approach. A discussion of the scope and limitations of current diagnostic practice, criticisms from different quarters, and the role and relevance of culture in the diagnostic encounter, precede the examination of advantages and disadvantages of the approach. The cultural content of psychiatric diagnosis should include the main, well-recognized cultural variables, adequate family data, explanatory models, and strengths and weaknesses of every individual patient. The practical aspects include the acceptance of "cultural discordances" as a component of an updated definition of mental disorder, and the use of a refurbished cultural formulation. Clinical "telescoping" strategies to obtain relevant cultural data during the diagnostic interview, and areas of future research (including field trials on the cultural formulation and on "culture bound syndromes"), are outlined.

Pediatric therapeutics and medicine administration in resource-poor settings: a review of barriers and an agenda for interdisciplinary approaches to improving outcomes

The lack of affordable, available pediatric drug formulations presents serious global health challenges. This article argues that successful pharmacotherapy for children demands an interdisciplinary approach. There is a need to develop new medicines to address acute and chronic illnesses of children, but also to produce formulations of essential medicines to optimize stability, bioavailability, palatability, cost, accurate dosing and adherence. This, in turn, requires an understanding of the social ecologies in which treatment occurs. Understanding health worker, caregiver and patient practices, limitations, and expectations with regard to medicines is crucial to guiding effective drug development and administration. Using literature on pediatric tuberculosis as a reference, this review highlights sociocultural, pharmacological, and structural barriers that impede the delivery of medicines to children. It serves as a basis for the development of an intensive survey of patient, caregiver, and health care worker understandings of, and preferences for, pediatric formulations in three East African countries.

Mental health, substance use and suicidal behaviour among young indigenous people in the Arctic: a systematic review

The Arctic has been a subject to various socio-cultural changes; indigenous people living in the region have experienced injustice and oppression in different forms. Furthermore, there are currently various new social, political and environmental challenges. It has been assumed that the continuous socio-cultural transition has an influence on indigenous people's wellbeing. We conducted a systematic literature review with regard to epidemiological mental health research on Arctic indigenous children and adolescents. The aim was to describe the nature and scope of research conducted and to explore for possible regional and ethnic differences in mental health. It was found that current epidemiological knowledge is based mainly on cross-sectional studies from selected regions and limited to substance use and suicidal behaviour. Youth suicide rates are alarmingly high in many parts of the Arctic, particularly in Greenland and Alaska. Differences between indigenous and non-indigenous groups are also most evident and uniform across suicide studies, with rates being systematically higher among indigenous youth. Substance use is common throughout the Arctic, however, regional and ethnic differences in usage vary considerably. Other psychosocial problems remain largely unexplored. In addition, very little is known about the causes of mental health problems in general and the impact of rapid socio-cultural changes in particular. There are several methodological limitations in the studies included here, many related to the validity of research instruments in different cultural contexts. There is a need for longitudinal comparative studies from the entire Arctic with culturally relevant instruments addressing mental health in early childhood as well.

Explaining Suicide in an Urban Slum of Mumbai, India

Background: Health demographic mortality studies use verbal autopsies to identify suicide as a cause of death. Psychological autopsies focus almost exclusively on associated high-risk psychiatric disorders. New approaches considering contextual factors are needed for preventing suicide and promoting mental health. Aims: This study examined explanations of suicide reported by surviving family members or close friends with reference to social, cultural, and environmental conditions as well as the challenges of life in the Malavani slum of Mumbai. Methods: An EMIC (Explanatory Model Interview Catalog) interview based on a cultural epidemiological framework considered underlying problems, perceived causes, and sociocultural contexts. It was administered to survivors of 76 people who had died by suicide (56.6% women). Results: Accounts of underlying problems typically referred to various aspects of tension (73.7%). Perceived causes often identified multiple factors. The sociocultural contexts of suicide included the victimization of women, the personal and social impact of problem drinking, marital problems, physical health problems, mental tension, possession and sorcery. Women were particularly vulnerable to the impact of problem drinking by a spouse or father. Conclusions: This study demonstrates the value of an approach to sociocultural autopsy examining local contexts and explanations of suicide. Findings highlight needs for both mental health services and culturally sensitive social interventions.

Oral cholera vaccine use in Zanzibar: socioeconomic and behavioural features affecting demand and acceptance

BACKGROUND

Cholera remains a serious public health problem in low-income countries despite efforts in the past to promote oral rehydration therapy as major treatment. In 2007, the majority of worldwide cases (94%) and deaths (99%) were reported from Africa. To improve cholera control efforts in addition to maintaining and improving existing water supply, sanitation and hygiene behaviour measures, the World Health Organization has recently started to consider the use of vaccines as an additional public health tool. To assess this new approach in endemic settings, a project was launched in Zanzibar to vaccinate 50,000 individuals living in communities at high risk of cholera with an oral two-dose vaccine (Dukoral). Immunisation programmes in low-income countries have suffered a reduced coverage or were even brought to a halt because of an ignorance of local realities. To ensure the success of vaccination campaigns, implementers have to consider community-held perceptions and behaviours regarding the infectious disease and the vaccine of interest. The main aim of this study is to provide advice to the Ministry of Health and Social Welfare of Zanzibar regarding routine introduction of an oral cholera vaccine from a socioeconomic and behavioural perspective as part of a long-term development for a sustained cholera prevention strategy.

METHODS AND DESIGN

Qualitative and quantitative methods of health social science research will be applied on four stakeholder levels before and after the mass vaccination campaign. Rapid assessment individual interviews and focus groups will be used to describe cholera- and vaccine-related views of policy makers, health care professionals and community representatives. The cultural epidemiological approach will be employed on the individual household resident level in a repeated cross-sectional design to estimate determinants of anticipated and actual oral cholera vaccine acceptance.

DISCUSSION

The study presented here is designed to inform about people's perceptions regarding cholera and about socioeconomic and behavioural factors determining anticipated and actual oral cholera vaccine acceptance in Zanzibar. Its pre- and post-intervention design using a mixed-methods approach on different stakeholder levels in communities at high risk of cholera outbreaks will ensure the collection of locally valid data relevant for public health action and planning.

Gender, suicide, and the sociocultural context of deliberate self-harm in an urban general hospital in Mumbai, India

Recognizing the complementary effects of social contexts and psychiatric disorders, this study clarifies the role of gender in suicidal behavior in urban Mumbai by considering psychiatric diagnoses and patient-identified sociocultural features. The cultural epidemiological approach suggests the critical impact of situational sociocultural factors that complement the customary psychopathological accounts for those who harm or kill themselves. The cultural epidemiology of deliberate self-harm (DSH), it is argued, is critical to planning for suicide prevention, community mental health and psychiatric practice. This study, based on a cultural epidemiological framework, compares male and female admissions for DSH, evaluating conditions with SCID-I and EMIC interviews. We assessed features and narratives of suicidal behavior, patient-identified underlying problems, their perceived causes and triggers. The study included 92 women and 104 men. A diagnosis of depressive disorder was made for 48.9 percent of women and 39.4 percent of men. Many patients (50.0 percent of women and 41.3 percent of men) did not fulfill the criteria for any diagnosis, or did so only for an adjustment disorder or a V-code. Men typically explained DSH with reference to work problems, financial problems and problem drinking. Women typically discussed domestic problems, in-law relations and victimization. Problem drinking affected women living with men who drank. Social and situational factors appear to play a relatively greater role than psychiatric illness in self-harm and suicide in Mumbai, as in other Asian studies, compared with Europe and North America.

Obstacles to prompt and effective malaria treatment lead to low community-coverage in two rural districts of Tanzania

Background

Malaria is still a leading child killer in sub-Saharan Africa. Yet, access to prompt and effective malaria treatment, a mainstay of any malaria control strategy, is sub-optimal in many settings. Little is known about obstacles to treatment and community-effectiveness of case-management strategies. This research quantified treatment seeking behaviour and access to treatment in a highly endemic rural Tanzanian community. The aim was to provide a better understanding of obstacles to treatment access in order to develop practical and cost-effective interventions.

Methods

We conducted community-based treatment-seeking surveys including 226 recent fever episodes in 2004 and 2005. The local Demographic Surveillance System provided additional household information. A census of drug retailers and health facilities provided data on availability and location of treatment sources.

Results

After intensive health education, the biomedical concept of malaria has largely been adopted by the community. 87.5% (78.2–93.8) of the fever cases in children and 80.7% (68.1–90.0) in adults were treated with one of the recommended antimalarials (at the time SP, amodiaquine or quinine). However, only 22.5% (13.9–33.2) of the children and 10.5% (4.0–21.5) of the adults received prompt and appropriate antimalarial treatment. Health facility attendance increased the odds of receiving an antimalarial (OR = 7.7) but did not have an influence on correct dosage. The exemption system for under-fives in public health facilities was not functioning and drug expenditures for children were as high in health facilities as with private retailers.

Conclusion

A clear preference for modern medicine was reflected in the frequent use of antimalarials. Yet, quality of case-management was far from satisfactory as was the functioning of the exemption mechanism for the main risk group. Private drug retailers played a central role by complementing existing formal health services in delivering antimalarial treatment. Health system factors like these need to be tackled urgently in order to translate the high efficacy of newly introduced artemisinin-based combination therapy (ACT) into equitable community-effectiveness and health-impact.

The development of valid subtypes for depression in primary care settings: a preliminary study using an explanatory model approach

A persistent theme in the debate on the classification of depressive disorders is the distinction between biological and environmental depressions. Despite decades of research, there remains little consensus on how to distinguish between depressive subtypes. This preliminary study describes a method that could be useful, if implemented on a larger scale, in the development of valid subtypes of depression in primary care settings, using explanatory models of depressive illness. Seventeen depressed Hispanic patients at an inner city general practice participated in explanatory model interviews. Participants generated illness narratives, which included details about symptoms, cause, course, impact, health seeking, and anticipated outcome. Two distinct subtypes emerged from the analysis. The internal model subtype was characterized by internal attributions, specifically the notion of an "injured self." The external model subtype conceptualized depression as a reaction to life situations. Each subtype was associated with a distinct constellation of clinical features and health seeking experiences. Future directions for research using explanatory models to establish depressive subtypes are explored.

Child and adolescent mental disorders: the magnitude of the problem across the globe

OBJECTIVE

Describe objectively the global gaps in policy, data gathering capacity, and resources to develop and implement services to support child mental health.

METHODS

Report on the World health Organization (WHO) child and adolescent mental health resources Atlas project. The Atlas project utilized key informants and was supplemented by studies that focused on policy. This report also draws on current epidemiological studies to provide a context for understanding the magnitude of the clinical problem.

RESULTS

Current global epidemiological data consistently reports that up to 20% of children and adolescents suffer from a disabling mental illness; that suicide is the third leading cause of death among adolescents; and that up to 50% of all adult mental disorders have their onset in adolescence. While epidemiological data appears relatively uniform globally, the same is not true for policy and resources for care. The gaps in resources for child mental health can be categorized as follows: economic, manpower, training, services and policy. Key findings from the Atlas project include: lack of program development in low income countries; lack of any policy in low income countries and absent specific comprehensive policy in both low and high income countries; lack of data gathering capacity including that for country-level epidemiology and services outcomes; failure to provide social services in low income countries; lack of a continuum of care; and universal barriers to access. Further, the Atlas findings underscored the need for a critical analysis of the 'burden of disease' as it relates to the context of child and adolescent mental disorders, and the importance of defining the degree of 'impairment' of specific disorders in different cultures.

CONCLUSIONS

The recent finding of substantial gaps in resources for child mental health underscores the need for enhanced data gathering, refinement of the economic argument for care, and need for innovative training approaches.

Malaria risk and access to prevention and treatment in the paddies of the Kilombero Valley, Tanzania

Background

The Kilombero Valley is a highly malaria-endemic agricultural area in south-eastern Tanzania. Seasonal flooding of the valley is favourable to malaria transmission. During the farming season, many households move to distant field sites (shamba in Swahili) in the fertile river floodplain for the cultivation of rice. In the shamba, people live for several months in temporary shelters, far from the nearest health services. This study assessed the impact of seasonal movements to remote fields on malaria risk and treatment-seeking behaviour.

Methods

A longitudinal study followed approximately 100 randomly selected farming households over six months. Every household was visited monthly and whereabouts of household members, activities in the fields, fever cases and treatment seeking for recent fever episodes were recorded.

Results

Fever incidence rates were lower in the shamba compared to the villages and moving to the shamba did not increase the risk of having a fever episode. Children aged 1–4 years, who usually spend a considerable amount of time in the shamba with their caretakers, were more likely to have a fever than adults (odds ratio = 4.47, 95% confidence interval 2.35–8.51). Protection with mosquito nets in the fields was extremely good (98% usage) but home-stocking of antimalarials was uncommon. Despite the long distances to health services, 55.8% (37.9–72.8) of the fever episodes were treated at a health facility, while home-management was less common (37%, 17.4–50.5).

Conclusion

Living in the shamba does not appear to result in a higher fever-risk. Mosquito nets usage and treatment of fever in health facilities reflect awareness of malaria. Inability to obtain drugs in the fields may contribute to less irrational use of drugs but may pose an additional burden on poor farming households. A comprehensive approach is needed to improve access to treatment while at the same time assuring rational use of medicines and protecting fragile livelihoods.

Cancer and communication in the health care setting: experiences of older Vietnamese immigrants, a qualitative study

BACKGROUND

As patients grow older, accurate communication with health care providers about cancer becomes increasingly important. However, little is known about the cancer communication experiences of older Asian immigrants.

OBJECTIVE

To learn about the cancer-related communication experiences of older Vietnamese immigrants from the insider perspective.

DESIGN

Qualitative study (grounded theory, constant comparative method) using individual interviews with older Vietnamese immigrants with the purpose of discussing how they learn about cancer. Interviews were conducted in Vietnamese.

PARTICIPANTS

Vietnamese immigrants aged 50-70 years, recruited through community-based organizations. Most had low education and limited English proficiency. The sample size of 20 was sufficient to achieve theoretical saturation.

RESULTS

We identified 3 categories of themes concerning informants' experiences with cancer communication in the health care setting: (1) attitudes about addressing screening with providers, (2) issues/problems communicating with physicians about cancer, and (3) language/translation difficulties. There was substantial overlap between informants who mentioned each theme category, and 40% of the participants mentioned all 3 categories.

CONCLUSION

Clinicians should be aware of and act upon specific cancer communication needs/challenges of their older immigrant patients. Moreover, health care systems need to be prepared to address the needs of an increasingly multiethnic and linguistically diverse patient population. Finally, community-level interventions should address baseline knowledge deficits while encouraging immigrant patients to engage their doctors in discussions about cancer screening.

Cultural differences in the experience of everyday symptoms: a comparative study of South Asian and European American women

This paper describes a study of medically ambiguous symptoms in two contrasting cultural groups. The study combined a qualitative, meaning-centered approach with a structured coding system and comparative design. Thirty-six South Asian immigrants and thirty-seven European Americans participated in a semistructured health history interview designed to elicit conceptual models of medically unexplained illness. The groups reported similar symptoms, but the organization of illness episodes and explanatory models associated with these episodes differed sharply. A variety of cultural variables and processes is proposed to account for observed differences, including somatization, the role of local illness categories, and the divergent core conflicts and values associated with gender roles. It is argued that the comparative design of the study provided insights that could not have been achieved through the study of a single group.

Diagnostic concordance of neurasthenia spectrum disorders in Pune, India

BACKGROUND

Clinically significant fatigue or weakness is a common but understudied clinical problem in India. The applicability and relevance of Western clinical criteria in this setting are not studied. Alternative criteria sets used in different clinical contexts suggest a range of conditions constituting neurasthenia spectrum disorders (NSDs). We therefore aimed to determine frequency of patients with these complaints in four specialty outpatient clinics of an urban general hospital. We compared the concordance of four diagnostic criteria sets of fatigue disorders among the same patients.

METHODS

Patients from the clinics of Psychiatry, Medicine, Dermatology, and Ayurved were screened for clinically significant fatigue or weakness and assessed for CFS, ICD-10 neurasthenia, DSM-IV draft criteria for neurasthenia, and CCMD-2 neurasthenia.

RESULTS

For 352 patients, sensitivity of CDC criteria for CFS (13.4%) was poorest. CFS was most frequent in the Medicine clinic. CCMD-2 criteria were the most frequently met (77.6%) with no significant difference across clinics. Two-way concordance of neurasthenia categories was no better than fair (< or =0.4) and few patients (8.0%) met criteria for all four categories.

DISCUSSION

Four NSD criteria sets identified different clinical subgroups. CFS, considering fatigue and ignoring weakness, was least relevant for identifying NSD patients in these clinics. Poor concordance among the four diagnostic systems studied indicates the need for reviewing the nosology of these disorders. Focus on clinical significance alone is likely to avoid the discordant confusion arising from cross-cultural differences.

Understanding and improving access to prompt and effective malaria treatment and care in rural Tanzania: the ACCESS Programme

Background

Prompt access to effective treatment is central in the fight against malaria. However, a variety of interlinked factors at household and health system level influence access to timely and appropriate treatment and care. Furthermore, access may be influenced by global and national health policies. As a consequence, many malaria episodes in highly endemic countries are not treated appropriately.

Project

The ACCESS Programme aims at understanding and improving access to prompt and effective malaria treatment and care in a rural Tanzanian setting. The programme's strategy is based on a set of integrated interventions, including social marketing for improved care seeking at community level as well as strengthening of quality of care at health facilities. This is complemented by a project that aims to improve the performance of drug stores. The interventions are accompanied by a comprehensive set of monitoring and evaluation activities measuring the programme's performance and (health) impact. Baseline data demonstrated heterogeneity in the availability of malaria treatment, unavailability of medicines and treatment providers in certain areas as well as quality problems with regard to drugs and services.

Conclusion

The ACCESS Programme is a combination of multiple complementary interventions with a strong evaluation component. With this approach, ACCESS aims to contribute to the development of a more comprehensive access framework and to inform and support public health professionals and policy-makers in the delivery of improved health services.

Health-related stigma: rethinking concepts and interventions

As a feature of many chronic health problems, stigma contributes to a hidden burden of illness. Health-related stigma is typically characterized by social disqualification of individuals and populations who are identified with particular health problems. Another aspect is characterized by social disqualification targeting other features of a person's identity-such as ethnicity, sexual preferences or socio-economic status-which through limited access to services and other social disadvantages result in adverse effects on health. Health professionals therefore have substantial interests in recognizing and mitigating the impact of stigma as both a feature and a cause of many health problems. Rendering historical concepts of stigma as a discrediting physical attribute obsolete, two generations of Goffman-inspired sociological studies have redefined stigma as a socially discrediting situation of individuals. Based on that formulation and to specify health research interests, a working definition of health-related stigma is proposed. It emphasizes the particular features of target health problems and the role of particular social, cultural and economic settings in developing countries. As a practical matter, it relates to various strategies for intervention, which may focus on controlling or treating target health problems with informed health and social policies, countering the disposition of perpetrators to stigmatize, and supporting those who are stigmatized to limit their vulnerability and strengthen their resilience. Our suggestions for health studies of stigma highlight needs for disease- and culture-specific research that serves the interests of international health.

A mixed-methods approach to understanding loneliness and depression in older adults

OBJECTIVE

Depression in late life may be difficult to identify, and older adults often do not accept depression treatment offered. This article describes the methods by which we combined an investigator-defined definition of depression with a person-derived definition of depression in order to understand how older adults and their primary care providers overlapped and diverged in their ideas about depression.

METHODS

We recruited a purposive sample of 102 persons aged 65 years and older with and without significant depressive symptoms on a standardized assessment scale (Center for Epidemiologic Studies-Depression scale) from primary care practices and interviewed them in their homes. We applied methods derived from anthropology and epidemiology (consensus analysis, semi-structured interviews, and standardized assessments) in order to understand the experience and expression of late-life depression.

RESULT

Loneliness was highly salient to older adults whom we asked to describe a depressed person or themselves when depressed. Older adults viewed loneliness as a precursor to depression, as self-imposed withdrawal, or as an expectation of aging. In structured interviews, loneliness in the week prior to interview was highly associated with depressive symptoms, anxiety, and hopelessness.

DISCUSSION

An improved understanding of how older adults view loneliness in relation to depression, derived from multiple methods, may inform clinical practice.

Socio-cultural determinants of treatment delay for childhood malaria in southern Ghana

We studied socio-cultural determinants of timely appropriate treatment seeking for children under 5 years suspected of having a perceived malaria-related illness. Caretakers of children with suspected malaria were interviewed about illness-related experiences, meanings and behaviour in two endemic villages in southern Ghana. Only 11% of children suspected of having a perceived malaria-related illness received timely appropriate treatment consistent with the Abuja target of treating malaria within 24 h of illness onset; 33% of children received appropriate treatment within 48 h. Reported perceived causes of phlegm predicted timely, appropriate treatment within 24 h of illness onset (P = 0.04) in a multivariate logistic regression model; playing on the ground (P < 0.01) predicted such treatment within 48 h. Two categories of distress, paleness or shortage of blood (P = 0.05) and sweating profusely (P = 0.03), also predicted timely, appropriate treatment within 24 h in a multivariate logistic regression model. Knowing that mosquitoes transmit malaria was not associated with timely, appropriate help seeking for the children, even though such knowledge may promote personal protective measures, especially use of bednets. Patterns of distress and PC were related to timely, appropriate help seeking, but not as expected. Effects on health seeking of illness-related experience and meaning are complex, and explaining their role may strengthen interventions for childhood malaria.

Cultural context and impact of alcohol use in the Sundarban Delta, West Bengal, India

Hazardous alcohol consumption is a worldwide problem with many locally distinctive features across cultures, but studies to guide policy in developing countries are notably lacking. This community study aimed to clarify local patterns of alcohol use in six villages of West Bengal, India. It considered the variety of local alcoholic preparations, who consumed them, when, and where. It sought to determine how social changes in the region influence changing patterns of acceptable and problem use of alcohol. Ethnographic methods included participant observation and focus group discussions. The qualitative data analysis of field notes and transcripts included a review of full texts and a computer-assisted analysis of thematically coded segments with reference to a structured agenda. We found that drinking is an integral feature of the cultural landscape. Locally brewed rice beer (handia), palm wine (tadi), distilled country liquor (chullu), and so-called Indian-made foreign liquor (IMFL) are consumed in these villages. Each is identified with particular segments of society and settings in these communities. Reported effects of problem drinking included social disturbances, family discord, and domestic violence. Increasing problem alcohol use was attributed by villagers to social changes resulting from development, which were otherwise valued, such as improved transportation and communications. In a field dominated by Western and urban studies, this research clarifies features of alcohol availability, use, and acceptance in a neglected rural area of India. It illustrates the limitations of western clinical models of dependence and the importance of clarifying sociocultural conditions that define locally acceptable and problem use.

Clinical diagnostic and sociocultural dimensions of deliberate self-harm in Mumbai, India

Patients' accounts complement psychiatric assessment of deliberate self-harm (DSH). In this study we examined psychiatric disorders, and sociocultural and cross-cultural features of DSH. SCID diagnostic interviews and a locally adapted EMIC interview were used to study 196 patients after DSH at a general hospital in Mumbai, India. Major depression was the most common diagnosis (38.8%), followed by substance use disorders (16.8%), but 44.4% of patients did not meet criteria for an enduring Axis-I disorder (no diagnosis, V-code, or adjustment disorder). Psychache arising from patient-identified sociocultural contexts and stressors complements, but does not necessarily fulfill, criteria for explanatory psychiatric disorders.

The view from the Hogan: cultural epidemiology and the return to ethnography

Alexander Leighton's seminal work has clearly demonstrated how ethnographic experience provides the rich cultural context in which epidemiological data are best interpreted. This article reviews recent trends in cultural epidemiology, and especially the emergence of the EMIC (Explanatory Model Interview Catalogue) as a quantitatively oriented tool designed to assess culture. It is suggested that such efforts do not reflect more recent trends in culture theory, and tend to view 'cultures' as easily bounded and largely homogenous units to facilitate the generation of quantitative data. It is argued that cultural epidemiologists should take a step back and ask, 'what is the culture in question here?' and 'how do I know if it is appropriate to place any given member of my sample into a specific cultural category?' before proceeding with any 'culturally appropriate' instrument. The answer to these questions begins with a return to ethnography as a means to elucidate and describe culture within the context in which it is being presented and studied.

Community concepts of malaria-related illness with and without convulsions in southern Ghana

Background

Malaria, both with or without convulsions, is a serious hardship for people living in endemic areas, especially in sub-Saharan Africa. Community references to malaria, however, may encompass other conditions, which was collectively designated malaria-related illness (MRI). Inasmuch as the presence or absence of convulsions reportedly affects timely help-seeking for malaria, a local comparison of these conditions is needed to inform malaria control.

Methods

Vignette-based EMIC interviews (insider-perspective interviews) for MRI with convulsions (convulsion positive, MRI-CP) and without convulsions (convulsion negative, MRI-CN) were developed to study relevant features of MRI-related experience, meaning and behaviour in two rural communities in Ghana. These semi-structured interviews elicited both qualitative narrative and categorical codes for quantitative analysis. Interviews with 201 respondents were conducted.

Results

The conditions depicted in the vignettes were well recognized by respondents and named with various local terms. Both presentations were considered serious, but MRI-CP was more frequently regarded potentially fatal than MRI-CN. More than 90.0% of respondents in both groups acknowledged the need to seek outside help. However, significantly more respondents advised appropriate help-seeking within 24 (p = 0.01) and 48 (p = 0.01) hours for MRI-CP. Over 50.0% of respondents responding to questions about MRI-CP identified MRI-CN as a cause of convulsions.

Conclusion

Local comparison of MRI-CP and MRI-CN based on vignettes found a similar profile of reported categories of perceived causes, patterns of distress, help-seeking and preventive measures for both presentations. This differs from previous findings in sub-Saharan Africa, which assert communities regard the two conditions to be unrelated. The perceived relationships should be acknowledged in formulating strategies to control malaria through timely help-seeking and treatment to reduce childhood mortality.

Impact of migration on illness experience and help-seeking strategies of patients from Turkey and Bosnia in primary health care in Basel

Migration, particularly among refugees and asylum seekers, poses many challenges to the health system of host countries. This study examined the impact of migration history on illness experience, its meaning and help-seeking strategies of migrant patients from Bosnia and Turkey with a range of common health problems in general practice in Basel, Switzerland. The Explanatory Model Interview Catalogue, a data collection instrument for cross-cultural research which combines epidemiological and ethnographic research approaches, was used in semi-structured one-to-one patient interviews. Bosnian patients (n=36) who had more traumatic migration experiences than Turkish/Kurdish (n=62) or Swiss internal migrants (n=48) reported a larger number of health problems than the other groups. Psychological distress was reported most frequently by all three groups in response to focussed queries, but spontaneously reported symptoms indicated the prominence of somatic, rather than psychological or psychosocial, problems. Among Bosnians, 78% identified traumatic migration experiences as a cause of their illness, in addition to a range of psychological and biomedical causes. Help-seeking strategies for the current illness included a wide range of treatments, such as basic medical care at private surgeries, outpatients department in hospitals as well as alternative medical treatments among all groups. Findings provide a useful guide to clinicians who work with migrants and should inform policy in medical care, information and health promotion for migrants in Switzerland as well as further education of health professionals on issues concerning migrants health.

[Finding a meaning for illness: from medical anthropology to cultural epidemiology]

Every illness raises questions concerning its causes and even more its meaning. Why me? Why him? Why now? These questions call for an interpretation which goes beyond a simple application to the individual body and the medical diagnosis. This search for meaning is by no means an archaic attitude and does not only concern the cryptic fields of medicine as several studies in medical anthropology and transcultural psychiatry have shown. A review of literature in anthropology points out the basic concepts of "health care system", "explanatory models", "etiological theories", and "causality of illness". The contribution of these studies to epidemiology and public health of infectious and tropical diseases is discussed through the development of so called cultural epidemiology based on the methodology of the Explanatory Model Interview Catalogue.

Somatization revisited: diagnosis and perceived causes of common mental disorders

The assessment of somatoform disorders is complicated by persistent theoretical and practical questions of classification and assessment. Critical rethinking of professional concepts of somatization suggests the value of complementary assessment of patients' illness explanatory models of somatoform and other common mental disorders. We undertook this prospective study to assess medically unexplained somatic symptoms and their patient-perceived causes of illness and to show how patients' explanatory models relate to professional diagnoses of common mental disorders and how they may predict the short-term course of illness. Tertiary care patients (N=186) with prominent somatoform symptoms were evaluated with the Structured Clinical Interview for DSM-IV, a locally adapted Explanatory Model Interview to elicit patients' illness experience (priority symptoms) and perceived causes, and clinical self-report questionnaires. The self-report questionnaires were administered at baseline and after 6 months. Diagnostic overlap between somatoform, depressive, and anxiety disorders occurred frequently (79.6%). Patients explained pure somatoform disorders mainly with organic causal attributions; they explained pure depressive and/or anxiety disorders mainly with psychosocial perceived causes, and patients in the diagnostic overlap group typically reported mixed causal attributions. In this last group, among patients with similar levels of symptom severity, organic perceived causes were related to a lower physical health sum score on the MOS Short Form, and psychosocial perceived causes were related to less severe depressive symptoms, assessed with the Hospital Anxiety and Depression Scale at 6 months. Among patients meeting criteria for comorbid somatoform with anxiety and/or depressive disorders, complementary assessment of patient-perceived causes, a key element of illness explanatory models, was related to levels of functional impairment and short-term prognosis. For such patients, causal attributions may be particularly useful to clarify clinically significant features of common mental disorders and thereby contribute to clinical assessment.

Cultural concepts of tuberculosis and gender among the general population without tuberculosis in rural Maharashtra, India

Gender-specific patterns of experience, meaning, and behaviour for tuberculosis (TB) require consideration to guide control programmes. To clarify concepts of gender, culture, and TB in a rural endemic population of Maharashtra, India, this study of 80 men and 80 women employed qualitative and quantitative methods of cultural epidemiology, using a locally adapted semi-structured Explanatory Model Interview Catalogue (EMIC) interviews are instruments for cultural epidemiological study of the distribution of illness-related experiences, meanings, and behaviours. This interview queried respondents without active disease about vignettes depicting a man and woman with typical features of TB. Emotional and social symptoms were frequently reported for both vignettes, but more often considered most distressing for the female vignette; specified problems included arranging marriages, social isolation, and inability to care for children and family. Job loss and reduced income were regarded most troubling for the male vignette. Men and women typically identified sexual experience as the cause of TB for opposite-sex vignettes. With wider access to information about TB, male respondents more frequently recommended allopathic doctors and specialty services. Discussion considers the practical significance of gender-specific cultural concepts of TB.

Schizophrenia and the cultural epidemiology of stigma in Bangalore, India

Illness-related stigma is a complex and important issue, and its social impact contributes to a hidden burden of many health problems. Mitigating effects of stigma are a priority for mental health policy, especially for schizophrenia. Although numerous studies document its impact on patients and their families, health studies of stigma typically regard it in global terms without adequate attention to the conceptual and practical importance of sociocultural contexts and the particular features of illness that evoke stigma. Research at a psychiatric referral center in Bangalore, India, studied the cultural epidemiology of schizophrenia and stigma in interviews with family caretakers of 60 patients, using a locally adapted EMIC interview and the Positive and Negative Symptom Scale. An index of 13 stigma queries based on Goffman's formulation covered relevant aspects and proved to be internally consistent (Cronbach alpha = 0.81). Multivariate statistical regression and qualitative analysis of narratives were used to analyze this stigma index and identify explanatory variables based on cultural patterns of distress (PD), perceived causes (PC), and previous help seeking (HS). Significant variables included suspiciousness and inappropriate sexual behavior (PD), heredity and bad deeds (PC), and informal help seeking (HS). Previous allopathic help seeking was negatively associated with stigma. Analysis of coded text segments from respondent narratives showed how these variables were related to family-perceived stigma, with reference to marriage practices, moral meanings of schizophrenia, and ways in which effective allopathic care minimized stigma. Findings identify features of schizophrenia-related stigma in India, contribute to comparative culture studies, and inform practical approaches to mitigate stigma through community awareness and improved mental health services.
