ESRD among Immigrants to Ontario, Canada: A Population-Based Study.

Background The epidemiology of ESRD requiring maintenance dialysis (ESRD-D) in large, diverse immigrant populations is unclear.Methods We estimated ESRD-D prevalence and incidence among immigrants in Ontario, Canada. Adults residing in Ontario in 2014 were categorized as long-term Canadian residents or immigrants according to administrative health and immigration datasets. We determined ESRD-D prevalence among these adults and calculated age-adjusted prevalence ratios (PRs) comparing immigrants to long-term residents. Among those who immigrated to Ontario between 1991 and 2012, age-adjusted ESRD-D incidence was calculated by world region and country of birth, with immigrants from Western nations as the referent group.Results Among 1,902,394 immigrants and 8,860,283 long-term residents, 1700 (0.09%) and 8909 (0.10%), respectively, presented with ESRD-D. Age-adjusted ESRD-D prevalence was higher among immigrants from sub-Saharan Africa (PR, 2.17; 95% confidence interval [95% CI], 1.84 to 2.57), Latin America and the Caribbean (PR, 2.11; 95% CI, 1.90 to 2.34), South Asia (PR, 1.45; 95% CI, 1.32 to 1.59), and East Asia and the Pacific (PR, 1.34; 95% CI, 1.22 to 1.46). Immigrants from Somalia (PR, 4.18; 95% CI, 3.11 to 5.61), Trinidad and Tobago (PR, 2.88; 95% CI, 2.23 to 3.73), Jamaica (PR, 2.88; 95% CI, 2.40 to 3.44), Sudan (PR, 2.84; 95% CI, 1.53 to 5.27), and Guyana (PR, 2.69; 95% CI, 2.19 to 3.29) had the highest age-adjusted ESRD-D PRs relative to long-term residents. Immigrants from these countries also exhibited higher age-adjusted ESKD-D incidence relative to Western Nations immigrants.Conclusions Among immigrants in Canada, those from sub-Saharan Africa and the Caribbean have the highest ESRD-D risk. Tailored kidney-protective interventions should be developed for these susceptible populations.

Behavioral and Academic Adjustment of Remotely Acculturating Adolescents in Urban Jamaica.

Remote acculturation (RA) is a modern form of non-migrant acculturation toward distant cultures prompted by indirect/intermittent globalization-related cultural exposure. RA theory holds that not only are global cultures now pouring into local neighborhoods, but many youth are also internalizing these remote cultures. How well do they fare? Prior studies in Jamaica and elsewhere have reported that U.S./Western-oriented adolescents exhibit poorer health habits. However, no studies have yet investigated adolescents' behavioral or academic adjustment in the context of RA, whether in Jamaica or elsewhere. Therefore, 245 adolescents and their mothers from high schools in Kingston, Jamaica (Madolescent_age   = 13.3; Mmother_age  = 40.2) completed questionnaires assessing their RA in terms of behaviors and values, as well as the adolescents' behavioral resilience and grades. SEM analyses revealed that RA was, indeed, linked to adolescent behavioral and academic adjustment in Jamaica. Overall, Jamaican orientation was associated with better adaptation whereas European American orientation was associated with worse.

Precarious patients: health professionals' perspectives on providing care to Mexican and Jamaican migrants in Canada's Seasonal Agricultural Worker Program.

INTRODUCTION: The intersecting vulnerabilities of migrant agricultural workers (MAWs) impact both their health and their access to health care in rural areas, yet rural clinicians' voices are rarely documented. The purpose of this study was to explore health professionals' perspectives on health care for MAWs in sending countries and rural Ontario, Canada. METHODS: Qualitative research design occurred over three distinct projects, using a multi-methodological approach including semi-structured interviews in Mexico, Jamaica and rural Ontario (n=43), and session field notes and questionnaires administered to healthcare providers (n=65) during knowledge exchange sessions in rural Ontario. A systematic analysis of these data was done to identify common themes, using NVivo software initially and then Microsoft Excel for application of a framework approach. RESULTS: Structural challenges posed by migrant workers' context included difficulties preventing and managing work-related conditions, employers or supervisors compromising confidentiality, and MAWs' fears of loss of employment and return to countries of origin prior to completing treatments. Structural challenges related to health services included lack of adequate translation/interpretation services and information about insurance coverage and MAWs' work and living situations; scheduling conflicts between clinic hours and MAWs' availability; and difficulties in arranging follow-up tests, treatments and examinations. Intercultural challenges included language/communication barriers; cultural barriers /perceptions; and limited professional knowledge of MAWs' migration and work contexts and MAWs' knowledge of the healthcare system. Transnational challenges arose around continuity of care, MAWs leaving Canada during/prior to receiving care, and dealing with health problems acquired in Canada. A range of responses were suggested, some in place and others requiring additional organization, testing and funding. CONCLUSION: Funding to strengthen responses to structural and intercultural challenges, including research assessing improved supports to rural health professionals serving MAWs, are needed in rural Canada and rural Mexico and Jamaica, in order to better address the structural and intersecting vulnerabilities and the care needs of this specific population.

Feel American, Watch American, Eat American? Remote Acculturation, TV, and Nutrition Among Adolescent-Mother Dyads in Jamaica.

Globalization prompts remote acculturation toward U.S. culture in Jamaica; this study used a bioecological systems approach to examine its proximal impact on nutrition through U.S. cable TV consumption, and maternal influences in the home. Overall, 330 randomly selected adolescent-mother dyads from schools in Kingston, Jamaica (Madolescent_age  = 13.8 years, SDadolescent_age  = 1.8) completed questionnaires reporting American identity and behavioral preferences, daily time spent watching U.S.-produced TV programs, and frequency of eating unhealthy foods. Actor-partner interdependence models revealed that girls' American identity/behavior directly predicted their unhealthy eating, whereas girls' mothers and boys' American identity/behavior indirectly predicted unhealthy eating as mediated by their U.S. TV hours. Additionally, mothers' American identity/behavior predicted daughters' unhealthy eating as mediated by mothers' U.S. TV hours. Remote acculturation theory may facilitate more targeted research and prevention/intervention.

Maternal Origin and Risk of Neonatal and Maternal ICU Admission.

OBJECTIVES: To evaluate maternal world region of birth, as well as maternal country of origin, and the associated risk of admission of 1) a mother to a maternal ICU, 2) her infant to a neonatal ICU, or 3) both concurrently to an ICU. DESIGN: Retrospective population-based cohort study. SETTING: Entire province of Ontario, Canada, from 2003 to 2012. PATIENTS: All singleton maternal-child pairs who delivered in any Ontario hospital. MEASUREMENTS AND MAIN RESULTS: We explored how maternal world region of birth, and specifically, maternal country of birth for the top 25 countries, was associated with the outcome of 1) neonatal ICU, 2) maternal ICU, and 3) both mother and newborn concurrently admitted to ICU. Relative risks were adjusted for maternal age, parity, income quintile, chronic hypertension, diabetes mellitus, obesity, dyslipidemia, drug dependence or tobacco use, and renal disease. Compared with infants of Canadian-born mothers (110.7/1,000), the rate of neonatal ICU admission was higher in immigrants from South Asia (155.2/1,000), Africa (140.4/1,000), and the Caribbean (167.3/1,000; adjusted relative risk, 1.41; 95% CI, 1.36-1.46). For maternal ICU, the adjusted relative risk was 1.79 (95% CI, 1.43-2.24) for women from Africa and 2.21 (95% CI, 1.78-2.75) for women from the Caribbean. Specifically, mothers from Ghana (adjusted relative risk, 2.71; 95% CI, 1.75-4.21) and Jamaica (adjusted relative risk, 2.74; 95% CI, 2.12-3.53) were at highest risk of maternal ICU admission. The risk of both mother and newborn concurrently admitted to ICU was even more pronounced for Ghana and Jamaica. CONCLUSIONS: Women from Africa and the Caribbean and, in particular, Ghana and Jamaica, are at higher risk of admission to ICU around the time of delivery, as are their newborns.

Prostate cancer among Jamaican men: exploring the evidence for higher risk.

BACKGROUND: Historically, black men of African descent have been disproportionately affected by prostate cancer compared with Caucasian men. African-Caribbean men are generally at higher risk of prostate cancer, with Jamaican men noted to have the highest incidence in the world. No robust evidence exists for the increased incidence among Jamaican men, or indeed, a clear explanation for the reasons these men are at a greater risk of developing the disease in comparison with other African-Caribbean men. METHODS AND FINDINGS: A literature review was undertaken. The findings indicated that black men of African descent, specifically Jamaican men, are at greater risk of prostate cancer and this finding applies to Africa, the Caribbean, the UK and USA. CONCLUSIONS: Current evidence for the higher incidence of prostate cancer among Jamaican men remains inconclusive and does not provide a clear explanation for its prevalence. More comparative studies are required to identify any predisposing factors responsible for this anomaly, worldwide. The involvement of health professionals in these research undertakings is important to obtaining insight into prostate cancer and in devising strategies to improve management and health outcomes.

Internationally recruited neonatal nurses' experiences in the National Health Service in London.

The aim of this study was to explore internationally recruited neonatal nurses' (IRNNs) perceptions of their experiences of working in the National Health Service (NHS) in London. This was an exploratory study. A purposive sample of 13 nurses (all females) from two teaching hospitals in London participated in this study. Semi-structured face-to-face interviews were used to capture IRNNs views of working in the NHS in London. Five themes emerged, namely: motivation to migrate, lack of preparation for neonatal nurses, environmental conditions impacting on care delivery, neonatal nurses deskilling, and role restrictions as well as professional development. The findings of this study provide first-hand insights from the subjective perspectives of IRNN experiences. IRNNs experienced some challenges to their working lives; however, good preparation is important when recruiting them to work in the NHS.

Obeah-illness versus psychiatric entities among jamaican immigrants: cultural and clinical perspectives for psychiatric mental health professionals.

In order to provide culturally authentic healthcare, psychiatric-mental health nurses and other professionals must familiarize themselves with the culture-specific syndromes, idioms of distress, beliefs and practices that may present among the diverse patient groups with whom they work. Psychiatric conditions relating to the Jamaican belief in "Obeah" are specific, culturally-interpreted phenomena that psychiatric nurses may encounter among Jamaican patients. This paper describes the phenomenon of Obeah and its influences on the worldview of life, health, illness; psychiatric conditions in the form of culture-bound syndromes; and help-seeking behaviors throughout Jamaican cultural communities. Inability to understand the obeah-illness concept from a culturally-interpreted perspective may be constrictive and result in less-than-optimal care. Armed with the knowledge of the concept of Obeah from a core belief perspective, how it influences psychiatric presentations, and embracing its significance to the Jamaican health belief model will assist in building a workable, caring, best-practice framework aimed toward a clinical and practice paradigm for this unique folk-health belief system.

The Influence of Spirituality on Health Behaviors in an Afro-Caribbean Population.

Spirituality is an integral part of the Afro-Caribbean experience. This study explored spirituality's influence on health in a church-going Afro-Caribbean population in order to further develop the concept of Spiritually-Guided Health risk Interception (SGHRI). Using a naturalistic approach, ten (10) members of local Pentecostal churches including ministry leaders, were interviewed. Items from the Spiritual Health Locus of Control scale (SHLC) guided the sessions. Content analysis was used to examine the data, and three themes emerged: compassion for service, divine authority, and shared responsibility. The findings of this study suggested that Afro Caribbean church-goers are fervent in their spirituality and dedication to social services provided by the church. While they rely on church leaders for guidance in health matters, recognition of personal role in health promotion was acknowledged. This valuable resource may be used to combine the fundamental principles associated with their spiritual practices and with health risk interceptions.

Demographic characteristics of world class Jamaican sprinters.

The dominance of Jamaican sprinters in international meets remains largely unexplained. Proposed explanations include demographics and favorable physiological characteristics. The aim of this study was to analyze the demographic characteristics of world class Jamaican sprinters. Questionnaires administered to 120 members of the Jamaican national team and 125 controls elicited information on place of birth, language, ethnicity, and distance and method of travel to school. Athletes were divided into three groups based on athletic disciplines: sprint (s: 100-400 m; n = 80), jump and throw (j/t: jump and throw; n = 25) and, middle distance (md: 800-3000 m; n = 15). Frequency differences between groups were assessed using chi-square tests. Regional or county distribution of sprint differed from that of middle distance (P < 0.001) but not from that of jump and throw athletes (P = 0.24) and that of controls (P = 0.59). Sprint athletes predominantly originated from the Surrey county (s = 46%, j/t = 37%, md = 17, C = 53%), whilst middle distance athletes exhibited excess from the Middlesex county (md = 60%). The language distribution of all groups showed uniformity with a predominance of English. A higher proportion of middle distance and jump and throw athletes walked to school (md = 80%, j/t = 52%, s = 10%, and C = 12%) and travelled greater distances to school. In conclusion, Jamaica's success in sprinting may be related to environmental and social factors.

Interdisciplinary approach to the demography of Jamaica.

BACKGROUND: The trans-Atlantic slave trade dramatically changed the demographic makeup of the New World, with varying regions of the African coast exploited differently over roughly a 400 year period. When compared to the discrete mitochondrial haplotype distribution of historically appropriate source populations, the unique distribution within a specific source population can prove insightful in estimating the contribution of each population. Here, we analyzed the first hypervariable region of mitochondrial DNA in a sample from the Caribbean island of Jamaica and compared it to aggregated populations in Africa divided according to historiographically defined segments of the continent's coastline. The results from these admixture procedures were then compared to the wealth of historic knowledge surrounding the disembarkation of Africans on the island. RESULTS: In line with previous findings, the matriline of Jamaica is almost entirely of West African descent. Results from the admixture analyses suggest modern Jamaicans share a closer affinity with groups from the Gold Coast and Bight of Benin despite high mortality, low fecundity, and waning regional importation. The slaves from the Bight of Biafra and West-central Africa were imported in great numbers; however, the results suggest a deficit in expected maternal contribution from those regions. CONCLUSIONS: When considering the demographic pressures imposed by chattel slavery on Jamaica during the slave era, the results seem incongruous. Ethnolinguistic and ethnographic evidence, however, may explain the apparent non-random levels of genetic perseverance. The application of genetics may prove useful in answering difficult demographic questions left by historically voiceless groups.

8q24 risk alleles in West African and Caribbean men.

BACKGROUND: Multiple genetic studies have confirmed associations of 8q24 variants with susceptibility to prostate cancer (CaP). However, the magnitude of risk conferred in men living in West Africa is unknown. METHODS: Here we determine the prevalence of 8q24 risk alleles and test for association with CaP risk alleles in West African (WA) descent populations from rural Nigeria, Cameroon, and the Caribbean island of Jamaica. Ten 8q24 SNPs were genotyped in histologically confirmed CaP cases (n = 308) and clinically evaluated controls (n = 469). In addition, unrelated individuals from Sierra Leone (n = 380) were genotyped for comparison of allele frequency comparisons. RESULTS: SNPs rs6983561, rs7008482, and rs16901979 were significantly associated with CaP risk in WAs (P < 0.03). No associations with CaP were observed in our Caribbean samples. Risk alleles for rs6983267, rs7008482, and rs7000448 were highly prevalent (>84%) in West Africa. We also reveal that the A-risk allele for the 'African-specific' SNP bd11934905 was not observed in 1,886 chromosomes from three WA ethnic groups suggesting that this allele may not be common across West Africa, but is geographically restricted to specific ethnic group(s). CONCLUSIONS: We provide evidence of association of 8q24 SNPs with prostate cancer risk in men from Nigeria and Cameroon. Our study is the first to reveal genetic risk due to 8q24 variants (in particular, region 2) with CaP within two WA countries. Most importantly, in light of the disparate burden of CaP in African-Americans, our findings support the need for larger genetic studies in WA descent populations to validate and discern function of susceptibility loci in the 8q24 region.

Is the prevalence of ER-negative breast cancer in the US higher among Africa-born than US-born black women?

Previous studies have reported that the prevalence of ER-negative tumors in breast cancer patients is much higher in black women than in white women in the US. Herein, we examine whether the proportion (prevalence) in Africa-born black breast cancer patients residing in the US is similar to those in US-born black patients. We obtained information on invasive female breast cancers diagnosed during 1996-2008 in 17 Surveillance Epidemiology and End Results cancer registries according to select place of birth: Western-Africa-born, Eastern-Africa-born, Jamaica-born, and US-born blacks and US-born whites. The majority of Western-Africa-born and Eastern-Africa-born blacks were from Nigeria (64 %) and Ethiopia (74 %), respectively. We examined group variations in ER status using Chi-squared tests and the prevalence of ER-negative tumors in Africa-born blacks compared to US-born blacks, expressed as prevalence ratio (PRR), using multivariable regression models. The prevalence of ER-negative tumors significantly varied from 22.0 % (n = 41/186) in Eastern-Africa-born to 32.9 % (n = 47/143) in Western-Africa-born blacks. After adjustment for differences in age at diagnosis and other covariates, compared to US-born blacks, the prevalence was similar in Western-Africa-born (PRR = 0.87; 95 % CI 0.70-1.08) and Jamaica-born blacks (PRR = 0.88; 95 % CI 0.74-1.03), but significantly lower in Eastern-Africa-born blacks (PRR = 0.58; 95 % CI 0.44-0.75). Notably, the ER-negative prevalence in Eastern-Africa-born black was comparable to the US-born whites with breast cancer. Our findings highlight the heterogeneity of breast cancer among black women in the US, which should be considered in future studies of hormone receptor status in these women.

Tridimensional acculturation and adaptation among Jamaican adolescent-mother dyads in the United States.

A bidimensional acculturation framework cannot account for multiple destination cultures within contemporary settlement societies. A tridimensional model is proposed and tested among Jamaican adolescent-mother dyads in the United States compared to Jamaican Islander, European American, African American, and other Black and non-Black U.S. immigrant dyads (473 dyads, M adolescent age = 14 years). Jamaican immigrants evidence tridimensional acculturation, orienting toward Jamaican, African American, and European American cultures. Integration is favored (70%), particularly tricultural integration; moreover, Jamaican and other Black U.S. immigrants are more oriented toward African American than European American culture. Jamaican immigrant youth adapt at least as well as nonimmigrant peers in Jamaica and the United States. However, assimilated adolescents, particularly first generation immigrants, have worse sociocultural adaptation than integrated and separated adolescents.

Health status of migrant farmworkers in the Shenandoah Valley.

The purpose of this study is to describe the characteristics and health status of a sample of migrant farmworkers in the Shenandoah Valley. The methodology for this study is a retrospective record review and analysis of data on 390 male migrant farmworkers. The group included men from Mexico (57. 2%), Jamaica (26. 9%), and Haiti (13. 0%) with a mean age of 38.5 years. The most common health problems reported were work-related and included musculoskeletal pain, irritated eyes, and respiratory symptoms. This study identifies areas for community and public health nurses to target interventions to address health promotion/disease prevention efforts.

Vesiculobullous variant of adult T-cell leukemia/lymphoma in a Caribbean Émigré.

Adult T-cell leukemia/lymphoma (ATLL) results from human T-cell lymphotropic virus (HTLV) type I infection and may present as a diverse array of cutaneous findings. Often these clinical manifestations are non-specific and overlap significantly with cutaneous T-cell lymphoma (CTCL). However, it is exceedingly rare for a patient suffering from ATLL to develop vesicular or bullous pathology and only a handful of such cases have been reported in the literature. The authors describe a patient of Jamaican descent afflicted with ATLL who developed an impressive vesiculobullous eruption. This case provides further support of the near complete clinical overlap between ATLL and CTCL. Patients from HTLV endemic areas with consistent clinical manifestations should have viral serologies drawn as the treatment and prognosis of ATLL and CTCL differ greatly.

Federal court allows application for judicial review of HIV-positive woman from Jamaica.

On 26 January 2011, the Federal Court allowed an application for judicial review by Ferona Elaine Mings-Edwards, who based her application for permanent residence on humanitarian and compassionate grounds, including the hardship that she claimed that she would face in Jamaica from her former domestic partner and because of her HIV-positive status.
