Knowledge, attitudes and practices of South Asian immigrants in developed countries regarding oral cancer: an integrative review.

BACKGROUND: Oral cancer is a growing problem worldwide, with high incidence rates in South Asian countries. With increasing numbers of South Asian immigrants in developed countries, a possible rise in oral cancer cases is expected given the high prevalence in their source countries and the continued oral cancer risk behaviours of immigrants. The aim of this review is to synthesise existing evidence regarding knowledge, attitudes and practices of South Asian immigrants in developed countries regarding oral cancer. METHODS: Five electronic databases were systematically searched to identify original, English language articles focussing on oral cancer risk knowledge, attitudes and practices of South Asian immigrants in developed countries. All studies that met the following inclusion criteria were included: conducted among South Asian immigrants in developed countries; explored at least one study outcome (knowledge or attitudes or practices); used either qualitative, quantitative or mixed methods. No restrictions were placed on the publication date, quality and setting of the study. RESULTS: A total of 16 studies involving 4772 participants were reviewed. These studies were mainly conducted in the USA, UK, Italy and New Zealand between 1994 and 2018. Findings were categorised into themes of oral cancer knowledge, attitudes and practices. General lack of oral cancer risk knowledge (43-76%) among participants was reported. More than 50% people were found engaging in one or more oral cancer risk practices like smoking, betel quid/pan/gutka chewing. Some of the participants perceived betel quid/pan/gutka chewing habit good for their health (12-43.6%). CONCLUSION: This review has shown that oral cancer risk practices are prevalent among South Asian immigrants who possess limited knowledge and unfavourable attitude in this area. Culturally appropriate targeted interventions and strategies are needed to raise oral cancer awareness among South Asian communities in developed countries.

"In our community, a friend is a psychologist": An ethnographic study of informal care in two Bhutanese refugee communities.

The recent rise in suicide among Bhutanese refugees has been linked to the erosion of social networks and community supports in the ongoing resettlement process. This paper presents ethnographic findings on the role of informal care practiced by relatives, friends, and neighbors in the prevention and alleviation of mental distress in two Bhutanese refugee communities: the refugee camps of eastern Nepal and the resettled community of Burlington, Vermont, US. Data gathered through interviews ( n = 40, camp community; n = 22, resettled community), focus groups (four, camp community), and participant observation (both sites) suggest that family members, friends, and neighbors were intimately involved in the recognition and management of individual distress, often responding proactively to perceived vulnerability rather than reactively to help-seeking. They engaged practices of care that attended to the root causes of distress, including pragmatic, social, and spiritual interventions, alongside those which targeted feelings in the "heart-mind" and behavior. In line with other studies, we found that the possibilities for care in this domain had been substantially constrained by resettlement. Initiatives that create opportunities for strengthening or extending social networks or provide direct support in meeting perceived needs may represent fruitful starting points for suicide prevention and mental health promotion in this population. We close by offering some reflections on how to better understand and account for informal care systems in the growing area of research concerned with identifying and addressing disparities in mental health resources across diverse contexts.

Update: vitamin B12 deficiency among Bhutanese refugees resettling in the United States, 2012.

In 2008, clinicians performing routine medical examinations in the United States reported high rates of hematologic and neurologic disorders caused by vitamin B12 deficiency in resettled Bhutanese refugees. To confirm this finding, CDC screened Bhutanese refugees' serum samples for vitamin B12 levels and found vitamin B12 deficiency in 64% (n = 99) of samples obtained before departure and 27% (n = 64) of samples obtained after arrival in the United States. In response, CDC recommended that arriving Bhutanese refugees receive oral vitamin B12 supplements and nutrition advice. In 2012, based on anecdotal reports of decreasing rates of vitamin B12 deficiency in this population, CDC worked with select domestic refugee health programs to determine if the recommendations had reduced the vitamin B12 deficiency rate among Bhutanese refugees.

Christchurch earthquakes: how did former refugees cope?

AIM: This study investigated how former refugees now living in Christchurch (Canterbury Province, New Zealand) communities coped after the 4 September 2010 and subsequent earthquakes. METHOD: A systematic sample of one in three former refugees from five ethnic groupings (Afghanistan, Kurdistan, Ethiopia, Somalia and Bhutan) was selected from a list of 317 refugees provided by the Canterbury Refugee Council and invited to participate in the study. Seventy-two out of 105 potential participants completed a 26 item questionnaire regarding the impact of the quakes, their concerns and anxieties, coping strategies and social supports. The methodology was complicated by ongoing aftershocks, particularly that of 22 February 2011. RESULTS: Three-quarters of participants reported that they had coped well, spirituality and religious practice being an important support for many, despite less then 20% receiving support from mainstream agencies. Most participants (72%) had not experienced a traumatic event or natural disaster before. Older participants and married couples with children were more likely to worry about the earthquakes and their impact than single individuals. There was a significant difference in the level of anxiety between males and females. Those who completed the questionnaire after the 22 February 2011 quake were more worried overall than those interviewed before this. CONCLUSION: Overall, the former refugees reported they had coped well despite most of them not experiencing an earthquake before and few receiving support from statutory relief agencies. More engagement from local services is needed in order to build trust and cooperation between the refugee and local communities.

Vitamin B12 deficiency in resettled Bhutanese refugees--United States, 2008-2011.

Since 2008, approximately 30,000 Bhutanese refugees have been resettled in the United States. Routine medical examinations of refugees after arrival in resettlement states indicated hematologic and neurologic disorders caused by vitamin B12 deficiency. These cases were reported by examining physicians and state health departments to CDC, which initiated an investigation. This report summarizes the results of that investigation. Sera from overseas medical examinations, postarrival examinations in three state health departments (Minnesota, Utah, and Texas), and medical records and interviews at a health clinic in St. Paul, Minnesota, were evaluated. Vitamin B12 deficiency, defined as serum vitamin B12 concentration <203 pg/mL, was found in 64% (63 of 99) of overseas specimens, 27% (17 of 64) of postarrival medical screenings, and 32% (19 of 60) of Bhutanese refugees screened for vitamin B12 deficiency at the St. Paul clinic. Although the deficiencies might be multifactorial, the main cause is thought to be the diet consumed by these refugees for nearly two decades in Nepal, which lacked meat, eggs, and dairy products, the major dietary sources of vitamin B12. Additionally, infection with Helicobacter pylori might play a role. Clinicians should be aware of the risk for vitamin B12 deficiency in Bhutanese refugees. All Bhutanese refugees should be given nutrition advice and should receive supplemental vitamin B12 upon arrival in the United States. In addition, refugees with clinical manifestations suggestive of deficiency should be tested for adequate serum vitamin B12 concentrations and, if found to have a B12 deficiency, screened for underlying causes, treated with parenteral vitamin B12 or high-dose oral supplements, and evaluated for response to therapy.

High success rate of TB treatment among Bhutanese refugees in Nepal.

SETTING: Camps for refugees from Bhutan in south-east Nepal. OBJECTIVES: To evaluate the outcome of treatment of tuberculosis (TB) cases in the refugee camps. DESIGN: Cohort analysis of results of treatment of cases started on treatment from mid-July 1999 to mid-July 2004. RESULT: A total of 1214 patients with TB were notified in the programme. Among these, 631 (52%) were new smear-positive pulmonary tuberculosis (PTB) cases, 175 (14%) new smear-negative PTB cases, 290 (24%) new extra-pulmonary TB (EPTB) cases and 118 (10%) smear-positive retreatment cases. Treatment success was achieved in 1061 (94%). The proportion of new non-smear-positive cases who died on treatment was significantly higher than the corresponding figure for new smear-positive cases (RR 7.57, 95%CI 3.74-15.32 for new smear-negative and 4.22, 95%CI 2.08-8.55 for EPTB). CONCLUSION: High cure rates and low bacteriological failure rates can be achieved in refugee settings if there is close coordination and collaboration between the local health agencies and the National Tuberculosis Programme of the host country.

Mental illness among Bhutanese shamans in Nepal.

Despite efforts to promote traditional medicine, allopathic practitioners often look with distrust at traditional practices. Shamans in particular are often regarded with ambivalence and have been considered mentally ill people. We tested the hypothesis that shamanism is an expression of psychopathology. In the Bhutanese refugee community in Nepal, a community with a high number of shamans, we surveyed a representative community sample of 810 adults and assessed ICD-10 mental disorders through structured diagnostic interviews. Approximately 7% of male refugees and 0.5% of female refugees reported being shamans. After controlling for demographic differences, the shamans did not differ from the comparison group in terms of 12-month and lifetime ICD-10 severe depressive episode, specific phobia, persistent somatoform pain, posttraumatic stress, generalized anxiety, or dissociative disorders. This first-ever, community-based, psychiatric epidemiological survey among shamans indicated no evidence that shamanism is an expression of psychopathology. The study's finding may assist in rectifying shamans' reputation, which has been tainted by past speculation of psychopathology.

Infectious disease surveillance during emergency relief to Bhutanese refugees in Nepal.

OBJECTIVE: To implement simplified infectious disease surveillance and epidemic disease control during the relocation of Bhutanese refugees to Nepal. DESIGN: Longitudinal observation study of mortality and morbidity. SETTING: Refugee health units in six refugee camps housing 73,500 Bhutanese refugees in the eastern tropical lowland between Nepal and India. INTERVENTIONS: Infectious disease surveillance and community-based programs to promote vitamin A supplementation, measles vaccination, oral rehydration therapy, and early use of antibiotics to treat acute respiratory infection. MAIN OUTCOME MEASURES: Crude mortality rate, mortality rate for children younger than 5 years, and cause-specific mortality. RESULTS: Crude mortality rates up to 1.15 deaths per 10,000 persons per day were reported during the first 6 months of surveillance. The leading causes of death were measles, diarrhea, and acute respiratory infections. Surveillance data were used to institute changes in public health management including measles vaccination, vitamin A supplementation, and control programs for diarrhea and acute respiratory infections and to ensure rapid responses to cholera, Shigella dysentery, and meningoencephalitis. Within 4 months of establishing disease control interventions, crude mortality rates were reduced by 75% and were below emergency levels. CONCLUSIONS: Simple, sustainable disease surveillance in refugee populations is essential during emergency relief efforts. Data can be used to direct community-based public health interventions to control common infectious diseases and reduce high mortality rates among refugees while placing a minimal burden on health workers.
