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.

A qualitative investigation of optimal perinatal health: the perspectives of south Asian grandmothers living in southern Ontario, Canada.

BACKGROUND: Perinatal health-seeking behaviours are influenced by various factors, including personal beliefs. South Asian women, who often live within a wide kinship system, can be influenced by the advice and guidance of their mothers and/or mothers-in-law. METHODS: To explore the cultural health perceptions of South Asian grandmothers within this context, we used constructivist grounded theory to sample and interview 17 South Asian grandmothers who reside in Southern Ontario, Canada. Interviews were audio-recorded, transcribed verbatim, and coded/analyzed by three independent coders. RESULTS: Many grandmothers emphasized that the preconception phase should focus on building healthy habits around nutrition, physical activity, and mental wellness; the pregnancy period should encompass an enriched environment (positive relationships, healthy routines, nutritional enhancement); and the postpartum phase should emphasize healing and restoration for both the mother and newborn (self-care, bonding, rebuilding healthy habits). Many of the grandmothers conceptualized these stages as a cyclical relationship where healing and restoration transitions gradually to re-establishing healthy habits before having a subsequent child. They also expressed responsibility in supporting their daughters and/or daughters-in-law with their family units and encouraging the transfer of perinatal health information. CONCLUSIONS: South Asian grandmothers are involved in supporting the family units of their children and involving them in perinatal health programming can be an effective way to translate health knowledge to South Asian women. Video abstract. In order to impact a broad, diverse audience of community members, we collaborated with a South Asian film-maker to distil the research findings, write an impactful script, and produce a short digital story based on the research findings. Currently available on social media (https://www.youtube.com/watch?v=tjcNUVOwatU), the film was celebrated with a CIHR Institute for Human Development, Child and Youth Health Video Talks Prize in 2016.

Developmental origins of variability in pelvic dimensions: Evidence from nulliparous South Asian women in the United Kingdom.

OBJECTIVES: Pelvic growth may be sensitive to early-life nutrition, with implications for maternal risk of obstructed labor. However, the "developmental origins" of adult pelvic variability require further investigation. We tested whether adult pelvic dimensions are associated with two components of height, indexing different periods of linear growth: tibia length, a proxy for early postnatal growth, and height-residual (height regressed on tibia length), a proxy for later growth. We also tested whether adult pelvic dimensions are associated with birth weight, a marker of nutritional investment in utero. METHODS: In this cross-sectional study, data were obtained on 68 nulliparous young women of South Asian ancestry. Pelvic dimensions (bi-iliac and bi-acetabular breadth, anteroposterior pelvic inlet and outlet, interspinous and intertuberous diameter) were measured using magnetic resonance imaging. Height and tibia length were measured manually. Birth weight and gestational age were obtained by recall. Multivariable regression models were fitted with a given pelvic dimension regressed on height-residual, tibia, and birth weight, with the latter adjusted for gestational age. RESULTS: Controlling for birth weight, height-residual was predictive of bi-acetabular breadth, bi-iliac breadth, and the pelvic inlet, while tibia length significantly predicted all dimensions except interspinous diameter. Controlling for the linear growth variables, birth weight was predictive of bi-iliac breadth only. CONCLUSIONS: Markers of linear growth during both early and later development were associated with adult pelvic dimensions, whereas size at birth was poorly predictive. Efforts to reduce stunting in early life may facilitate the attainment of maximum potential growth for both height and the pelvis.

Perceptions of palliative care in a South Asian community: findings from an observational study.

BACKGROUND: Patients often view "palliative care" (PC) as an approach that is synonymous with end-of-life and death, leading to shock and fear. Differing cultural and social norms and religious affiliations greatly determine perception of PC among diverse populations. METHODS: This prospective observational study aimed to explore perceptions of PC among South Asian community members at one Canadian site. Patients who identified themselves as being of South Asian origin were consented and enrolled at a PC Clinic at a community hospital in Brampton, Ontario serving a large South Asian population. Participants filled out an 18-question survey created for the study and responded to a semi-structured interview consisting of 8 questions that further probed their perceptions of PC. Survey responses and semi-structured interviews content were analyzed by four authors who reached consensus on key exploratory findings. RESULTS: Thirty-four participants of South Asian origin were recruited (61.8% males), and they were distributed by their age group as follows: [(30-49) - 18%; (50-64) - 21%; (65-79) - 41%; (≥ 80) - 21%]. Five main exploratory findings emerged: (i) differing attitudes towards talking about death; (ii) the key role of family in providing care; (iii) a significant lack of prior knowledge of PC; (iv) a common emphasis on the importance of alleviating suffering and pain to maintain comfort; and (v) that cultural values, faith, or spiritual belief do not pose a necessary challenge to acceptance of PC services. CONCLUSIONS: Observations from this study provide a source of reference to understand the key findings and variability in perceptions of palliative care in South Asian communities. Culturally competent interventions based on trends observed in this study could assist Palliative Physicians in delivering personalized care to South Asian populations.

Treatment of alcohol use disorder among people of South Asian ancestry in Canada and the United States: A narrative review.

To explore access and treatment for alcohol use disorders (AUDs) among people of South Asian ancestry living in Canada or the United State, EQUATOR guidelines were applied to 34 manuscripts identified through an English language literature search (1946-2017) for this narrative review. The population studied has poor access to and engagement with treatment for AUD. Early evidence suggests benefit from adopting language-specific materials, offering South Asian-specific therapy groups, and incorporating traditional healers. Specific engagement and therapy considerations may increase AUD treatment access and effectiveness among South Asians living in Canada or the United States.

[Study on parent-to-child transmission related to Sri Lanka's civil war]. / La transmission parents-enfants liée à la guerre civile du Sri Lanka.

The dynamics of transmission between Tamil parents who fled the civil war in Sri Lanka and their children born in France were studied. The possible trauma that results from the transmission can affect the following generations in a more or less conscious way. The qualitative methodology was based on T-MADE, a method of transcultural analysis of the children's drawings, linked to the analysis of the parents' narrative.

A lifestyle intervention programme for the prevention of Type 2 diabetes mellitus among South Asian women with gestational diabetes mellitus [LIVING study]: protocol for a randomized trial.

AIM: This study aims to determine whether a resource- and culturally appropriate lifestyle intervention programme in South Asian countries, provided to women with gestational diabetes (GDM) after childbirth, will reduce the incidence of worsening of glycaemic status in a manner that is affordable, acceptable and scalable. METHODS: Women with GDM (diagnosed by oral glucose tolerance test using the International Association of the Diabetes and Pregnancy Study Groups criteria) will be recruited from 16 hospitals in India, Sri Lanka and Bangladesh. Participants will undergo a repeat oral glucose tolerance test at 6 ± 3 months postpartum and those without Type 2 diabetes, a total sample size of 1414, will be randomly allocated to the intervention or usual care. The intervention will consist of four group sessions, 84 SMS or voice messages and review phone calls over the first year. Participants requiring intensification of the intervention will receive two additional individual sessions over the latter half of the first year. Median follow-up will be 2 years. The primary outcome is the proportion of women with a change in glycaemic category, using the American Diabetes Association criteria: (i) normal glucose tolerance to impaired fasting glucose, or impaired glucose tolerance, or Type 2 diabetes; or (ii) impaired fasting glucose or impaired glucose tolerance to Type 2 diabetes. Process evaluation will explore barriers and facilitators of implementation of the intervention in each local context, while trial-based and modelled economic evaluations will assess cost-effectiveness. DISCUSSION: The study will generate important new evidence about a potential strategy to address the long-term sequelae of GDM, a major and growing problem among women in South Asia.

Stillbirth in relation to maternal country of birth and other migration related factors: a population-based study in Norway.

BACKGROUND: Migrant women's overall increased risk of adverse pregnancy outcomes is well known. The aim of this study was to investigate possible associations between stillbirth and maternal country of birth and other migration related factors (paternal origin, reason for immigration, length of residence and birthplace of firstborn child) in migrant women in Norway. METHODS: Nationwide population-based study including births to primiparous and multiparous migrant women (n = 198,520) and non-migrant women (n = 1,156,444) in Norway between 1990 and 2013. Data from the Medical Birth Registry of Norway and Statistics Norway. Associations were investigated by multiple logistic regression and reported as odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Primiparous women from Sri-Lanka and Pakistan, and multiparous women from Pakistan, Somalia, the Philippines and Former Yugoslavia had higher odds of stillbirth when compared to non-migrant women (adjusted OR ranged from 1.58 to 1.79 in primiparous and 1.50 to 1.71 in multiparous women). Primiparous migrant women whose babies were registered with Norwegian-born fathers had decreased odds of stillbirth compared to migrant women whose babies were registered with foreign-born fathers (aOR = 0.73; CI 0.58-0.93). Primiparous women migrating for work or education had decreased odds of stillbirth compared to Nordic migrants (aOR = 0.58; CI 0.39-0.88). Multiparous migrant women who had given birth to their first child before arriving in Norway had higher odds of stillbirth in later births in Norway compared with multiparous migrant women who had their first child after arrival (aOR = 1.28; CI 1.06-1.55). Stillbirth was not associated with length of residence in Norway. CONCLUSIONS: This study identifies sub-groups of migrant women who are at an increased risk of stillbirth, and highlights the need to improve care for them. More attention should be paid to women from certain countries, multiparous women who had their first baby before arrival and primiparous women whose babies have foreign-born fathers.

Drinking water and chronic kidney disease of unknown aetiology in Anuradhapura, Sri Lanka.

This paper examines how people in Anuradhapura District in Sri Lanka affected by endemic chronic kidney disease of unknown aetiology (CKDu) explain the factors causing the illness and their cultural meanings. The research found that the issue of contaminated water raised by the local community and the cultural meaning of water have influenced the government policy, health programmes, research agendas and the work of the media. Media reports on sociocultural, biomedical and epidemiological research into the aetiology of kidney disease have strengthened the perspective of the villagers who believe that polluted water has a direct relationship to kidney disease. This new understanding among villagers in Anuradhapura District has led to changes in their behaviours relating to the use and consumption of water, an important factor that has reinforced existing social hierarchies.

Differences in prevalence of diabetes among immigrants to Canada from South Asian countries.

AIMS: The prevalence of diabetes is high in South Asians migrants. However, most previous research has studied South Asians as a collective whole. The aim of this study was to examine diabetes prevalence among immigrants from five South Asian countries living in Ontario, Canada. METHODS: Population-based health care and immigration databases were used to compare crude and adjusted diabetes prevalence on 1 January 2012 between immigrants to Ontario from different South Asians countries and the non-immigrant population. The prevalence of diabetes was also stratified by various sociodemographic factors. RESULTS: There were 431 765 first-generation South Asian immigrants; 68 440 (crude prevalence of 15.9%) of whom had a diagnosis of diabetes. After standardization for age, sex and income, diabetes prevalence was highest among South Asians from Sri Lanka (26.8%) followed by Bangladesh (22.2%), Pakistan (19.6%), India (18.3%) and Nepal (16.5%) in comparison with the non-immigrant population (11.6%). Increased prevalence was evident among men compared with women in each country of South Asia. Sociodemographic indicators including income, education, English proficiency and refugee status were associated with increased prevalence of diabetes in specific populations from South Asia. CONCLUSION: Striking differences in the prevalence of diabetes are evident among immigrants from different countries of South Asia. Awareness of the heterogeneity will help in recognizing priorities for the delivery of primary care for specific South Asian migrant populations with a range of settlement needs that also encompass social determinants of health.

Cross-cultural generalizability of suicide first aid actions: an analysis of agreement across expert consensus studies from a range of countries and cultures.

BACKGROUND: A number of Delphi expert consensus studies have been carried out with different countries and cultural groups to develop guidelines on how a member of the public should provide assistance to a person who is suicidal. The present study aimed to determine whether cross-culturally generalizable suicide first aid actions are possible by comparing agreement across these Delphi studies. METHODS: Data on endorsement rates for items were compared across six Delphi studies. These studies involved panels of professionals and consumer advocates from English-speaking countries, professionals from Sri Lanka, professionals from Japan, professionals from India, professionals from the Philippines, and professionals and consumer advocates in refugee and immigrant mental health. Correlations were calculated between item endorsement rates across panels. RESULTS: There were 18 items that were highly endorsed across all eight of the Delphi panels and an additional 15 items highly endorsed across the panels from the three lower middle-income countries (India, Philippines and Sri Lanka). Correlations across panels in item endorsement rates were all 0.60 or above, but were higher between panels from countries that are socioeconomically similar. CONCLUSIONS: There is broad agreement across the diverse expert panels about what are appropriate suicide first aid actions for members of the public, indicating that cross-cultural generalizability is possible. However, there is also some cultural specificity, indicating the need for local tailoring.

Seeking Help for Harm from Others' Drinking in Five Asian Countries: Variation Between Societies, by Type of Harm and by Source of Help.

AIMS: This study aims to measure the prevalence rates and patterns of help-seeking behavior as a consequence of being harmed by drinkers in five Asian countries (India, Sri Lanka, Vietnam, Lao PDR and Thailand). METHODS: A total of 9832 respondents aged 18-65 years from the WHO/ThaiHealth Collaborative Project were surveyed between 2012 and 2014 about their experiences of being negatively affected due to another's drinking, and whether and where they sought help, focusing on four adverse aspects of harms from others' drinking. RESULTS: The prevalence of seeking help from any source in the past year due to harm from others' drinking ranged from 7% to 20%. The most common service used by those who were affected by other people's drinking was asking for help from friends, followed by calling the police and using health-related services. The largest proportion of help-seeking was among those reporting property harm, followed by those being harmed physically and sexually by drinkers. CONCLUSION: Given a wide range of harms from others' drinking in the general population and different needs of those affected, prevalence rates for help-seeking behavior due to others' drinking in South and South East Asian countries were low and the help sought was often informal. There is a large knowledge gap in our understanding of the mechanisms of help-seeking behavior and the pathways for access to help among those affected. Further studies are important for enhancing the social response services available and making these more accessible to those who need help.

Betel quid chewing among adult male immigrants from the Indian subcontinent to Italy.

OBJECTIVE: Betel quid chewing (BQC) is an important oral cancer risk factor widespread in the Indian subcontinent. This usage also is common among migrants from this region. As the number of immigrants from South-East Asia is dramatically increasing in Italy, this survey was aimed at investigating BQC prevalence among immigrants from the Indian subcontinent. SUBJECTS AND METHODS: First-generation adult male immigrants coming from Pakistan, India, Sri Lanka, and Bangladesh, living in Rome, were consecutively selected. They were interviewed using a validated questionnaire. Descriptive statistics were performed, and factors associated to regular BQC were investigated through regression analysis. RESULTS: A total of 211 subjects (mean age, 33.8 years) living in Rome for 11 years, on average, participated in the study. BQC prevalence was 37.9% with few differences between Pakistani, Sri Lankans, and Indians. Prevalence among Bangladeshi was 7.3%. 69% of the consumers chewed BQ at least twice daily, 90% chewed BQ with tobacco; 30.3% subjects were smokers and chewers. Chewing parents, smoking, health illiteracy were associated with BQC. Most chewers believed that BQ helps to relieve stress. CONCLUSIONS: The number of oral cancers in Italy is expected to increase because of BQC dissemination. Therefore, specific awareness campaigns directed to residents of South-East Asian origin are needed.

Agency, activation and compatriots: the influence of social networks on health-seeking behaviours among Sri Lankan migrants and Anglo-Australians with depression.

The nexus between social networks and illness behaviours is important in uptake of health care, however scant research has explored this relationship in South Asian migrants living with mental illness. We explored the interplay between culture, social networks and health seeking in Sri Lankan migrants and Anglo-Australians living with depression. Forty-eight in-depth interviews were conducted and data were analysed through the theoretical prism of the network episode model. Results showed that social networks were important in negotiating care. Decisions to initiate care occurred along a continuum of choice and agency; some took charge of their care, others were coerced into care, however some Sri Lankan migrants were led through various informal channels of care. Selective activation of compatriots - those perceived to understand mental illness-became increasingly important to participants through their illness careers. Compatriots were considered of greater benefit as participants progressed through depression than otherwise meaningful social networks based on ethnicity, culture and kinship. We argue that the role of social networks is pivotal in uptake of formal care, and engaging with communities to improve responses of social networks to mental illnesses may provide a bottom-up avenue for improving uptake of mental health services in migrant communities.

"If One Does Not Fulfil His Duties, He Must Not Be a Man": Masculinity, Mental Health and Resilience Amongst Sri Lankan Tamil Refugee Men in Canada.

Refugee men face unique mental health stressors in the pre- and post-migratory periods. However, there has been little in-depth research on the mental health of refugee men in Canada. Given this situation, the overall aim of this study is to explore the psycho-social experience of Sri Lankan Tamil refugee men in Canada. Particular objectives include better understanding any inter-relationship between war-trauma, migration, concepts of masculinity and mental health. The study employed a two-phase participatory action research design based on the grounded theory approach. Phase 1 involved an 8-month ethnography conducted in Sri Lanka. Phase 2 consisted of qualitative interviews with 33 Sri Lankan Tamil refugee men living in Canada. Consistent with grounded theory, analysis was conducted inductively and iteratively. Four specific themes emerged from the data (i) gendered helplessness of war: participants commonly reported ongoing negative rumination regarding experiences where they were unable to adequately protect loved ones from physical suffering or death; (ii) reduced capacity: participants frequently felt unable to fulfill culturally sanctioned duties, such as supporting their family, due to ongoing pre- and post-migratory stress; (iii) redundancy: many participants felt that they were useless in Canada, as they could not fulfill typical masculine social roles (e.g. provider) due to factors such as unemployment and underemployment; (iv) intimate criticism: some participants reported that their spouses would often attempt to 'shame' them into greater achievement by constantly reminding them of their 'failures'. Many found this distressing. These various failures culminated in a state that we label "depleted masculinity", which participants linked to emotional and behavioural problems. Participants reported that they actively tried to rebuild their masculine identity, for example by adopting leadership roles in community organizations, which fostered resiliency. Results suggest a need to review and rebuild masculine identity to support the mental health of refugee men.

Health seeking narratives of unwell Sri Lankan Tamil refugees in Melbourne Australia.

Sri Lankan Tamil refugees are among the largest group of refugees to resettle in Australia in the last decade. The aim of this study is to characterise the narratives of health-seeking among unwell Sri Lankan Tamil refugees in Melbourne, Victoria, Australia. Drawing on a qualitative, phenomenological perspective, we conducted in-depth interviews in Tamil and English with 12 participants who identified as being unwell for 6 months or more. Findings revealed three narratives of health-seeking: the search for the 'good life' that was lost or never experienced, seeking help from familiar channels in an unfamiliar context, and the desire for financial and occupational independence. These three narratives are undergirded by the metanarrative of a hope-filled recovery. These narratives of Tamil refugees' lived experience provide new insights into clinical care and health service delivery.

Comorbidity of Posttraumatic Stress Disorder and Depression in Tortured, Treatment-Seeking Refugees.

Comorbid posttraumatic stress disorder (PTSD) and depression is common in refugee groups; however, little is known about the predictors and correlates of comorbidity in treatment-seeking refugees. Participants in this study were 134 refugees resettled in Switzerland. Most participants were from Turkey, Iran, and Sri Lanka, and 92.7% had been exposed to torture. Self-report measures were implemented to assess PTSD, depression, mental and physical health-related quality of life (QoL), as well as pre- and postmigration experiences. Findings indicated that approximately half the sample met criteria for PTSD and depression, 33.6% met criteria for depression only, and only 2.2% met criteria for PTSD only. Several variables emerged as predictors of comorbidity in contrast to no diagnosis: female gender, odds ratio (OR) = 0.17; age, OR = 0.93; time in Switzerland, OR = 1.16; and trauma exposure, OR = 1.19. Postmigration stress was also associated with greater likelihood of comorbidity compared with no diagnosis, OR = 1.32, and a single diagnosis, OR = 1.14. Further, dual diagnosis was associated with significantly poorer mental health-related and physical health-related QoL (mental health-related QoL: dual diagnosis vs. single diagnosis, d = -0.52 and dual diagnosis vs. no diagnosis, d = -1.30; physical health-related QoL: dual diagnosis vs. single diagnosis, d = -0.73 and dual diagnosis vs. no diagnosis: d = -1.04). Findings indicated that comorbidity was highly prevalent in this sample of treatment-seeking refugees and was associated with a substantial impairment burden. Psychological interventions for refugees should consider the dual impact of PTSD and depression symptoms to optimally decrease distress and improve QoL in this vulnerable group.

Provider- and patient-related determinants of diabetes self-management among recent immigrants: Implications for systemic change.

OBJECTIVE: To examine provider- and patient-related factors associated with diabetes self-management among recent immigrants. DESIGN: Demographic and experiential data were collected using an international survey instrument and adapted to the Canadian context. The final questionnaire was pretested and translated into 4 languages: Mandarin, Tamil, Bengali, and Urdu. SETTING: Toronto, Ont. PARTICIPANTS: A total of 130 recent immigrants with a self-reported diagnosis of type 2 diabetes mellitus who had resided in Canada for 10 years or less. MAIN OUTCOME MEASURES: Diabetes self-management practices (based on a composite of 5 diabetes self-management practices, and participants achieved a score for each adopted practice); and the quality of the provider-patient interaction (measured with a 5-point Likert-type scale that consisted of questions addressing participants' perceptions of discrimination and equitable care). RESULTS: A total of 130 participants in this study were recent immigrants to Canada from 4 countries of origin-Sri Lanka, Bangladesh, Pakistan, and China. Two factors were significant in predicting diabetes self-management among recent immigrants: financial barriers, specifically, not having enough money to manage diabetes expenses (P = .0233), and the quality of the provider-patient relationship (P = .0016). Participants who did not have enough money to manage diabetes were 9% less likely to engage in self-management practices; and participants who rated the quality of their interactions with providers as poor were 16% less likely to engage in self-management practices. CONCLUSION: Financial barriers can undermine effective diabetes self-management among recent immigrants. Ensuring that patients feel comfortable and respected and that they are treated in culturally sensitive ways is also critical to good diabetes self-management.

Genetic diversity of variants involved in drug response and metabolism in Sri Lankan populations: implications for clinical implementation of pharmacogenomics.

BACKGROUND: Interpopulation differences in drug responses are well documented, and in some cases they correspond to differences in the frequency of associated genetic markers. Understanding the diversity of genetic markers associated with drug response across different global populations is essential to infer population rates of drug response or risk for adverse drug reactions, and to guide implementation of pharmacogenomic testing. Sri Lanka is a culturally and linguistically diverse nation, but little is known about the population genetics of the major Sri Lankan ethnic groups. The objective of this study was to investigate the diversity of pharmacogenomic variants in the major Sri Lankan ethnic groups. METHODS: We examined the allelic diversity of more than 7000 variants in genes involved in drug biotransformation and response in the three major ethnic populations of Sri Lanka (Sinhalese, Sri Lankan Tamils, and Moors), and compared them with other South Asian, South East Asian, and European populations using Wright's Fixation Index, principal component analysis, and STRUCTURE analysis. RESULTS: We observed overall high levels of similarity within the Sri Lankan populations (median FST=0.0034), and between Sri Lankan and other South Asian populations (median FST=0.0064). Notably, we observed substantial differentiation between Sri Lankan and European populations for important pharmacogenomic variants related to warfarin (VKORC1 rs9923231) and clopidogrel (CYP2C19 rs4986893) response. CONCLUSION: These data expand our understanding of the population structure of Sri Lanka, provide a resource for pharmacogenomic research, and have implications for the clinical use of genetic testing of pharmacogenomic variants in these populations.

'We are all scared for the baby': promoting access to dental services for refugee background women during pregnancy.

BACKGROUND: Vulnerable populations such as people with refugee backgrounds are at increased risk of poor oral health. Given that maternal characteristics play a significant role in the development of dental caries in children, antenatal care offers an opportunity to both provide information to women about the importance of maternal oral health and accessing dental care. Although pregnant women are recognised for 'priority' care under Victorian state-government policy, rarely do they attend. This study aims to describe Afghan and Sri Lankan women's knowledge and beliefs surrounding maternal oral health, barriers to accessing dental care during pregnancy, and to present the perspectives of maternity and dental service providers in relation to dental care for pregnant women. METHODS: One agency comprising both dental and maternity services formed the setting for the study. Using participatory methods that included working with bicultural community workers, focus groups were conducted with Afghan and Sri Lankan refugee background participants. Focus groups were also completed with midwives and dental service staff. Thematic analysis was applied to analyse the qualitative data. RESULTS: Four community focus groups were conducted with a total of 14 Afghan women, eight Sri Lankan women, and three Sri Lankan men. Focus groups were also conducted with 19 dental staff including clinicians and administrative staff, and with ten midwives. Four main themes were identified: perceptions of dental care during pregnancy, navigating dental services, maternal oral health literacy and potential solutions. Key findings included women and men's perception that dental treatment is unsafe during pregnancy, the lack of awareness amongst both the midwives and community members of the potential impact of poor maternal oral health and the overall lack of awareness and understanding of the 'priority of access' policy that entitles pregnant women to receive dental care cost-free. CONCLUSION: This study highlights a significant policy-to-practice gap which if not addressed has the potential to widen oral health inequalities across the life-course. Stakeholders were keen to collaborate and support action to improve the oral health of mothers and their infants with the over-riding priority being to develop inter-service relationships to promote seamless access to oral health care.
