Jagroep W, Cramm JM, Denktaș S, Nieboer AP. Behaviour change interventions to promote health and well-being among older migrants: A systematic review. PLoS One 2022; 17:e0269778. [PMID: 35709205 PMCID: PMC9202883 DOI: 10.1371/journal.pone.0269778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 05/27/2022] [Indexed: 11/25/2022] Open
Abstract
Background Whether behaviour change interventions are effective for the maintenance of older migrants’ health and well-being is uncertain. A systematic review was conducted to assess evidence for the capacity of behaviour change techniques (BCTs) to promote the health and well-being of older migrants. Methods Electronic databases (Cochrane CENTRAL, Embase, Ovid MEDLINE and Web of Science) were searched systematically to identify relevant randomised controlled trials, pre–post studies and quasi-experimental studies published before March 2021. Additional articles were identified through citation tracking. Studies examining BCTs used to promote the health and/or well-being of older migrants were eligible. Two independent reviewers used the Behaviour Change Technique Taxonomy version 1 to extract data on BCTs. Data on intervention functions (IFs) and cultural adaption strategies were also extracted. Intervention contents (BCTs, IFs, culture adaption strategies) were compared across effective and ineffective interventions according to health and well-being outcome clusters (anthropometrics, health behaviour, physical functioning, mental health and cognitive functioning, social functioning and generic health and well-being). Results Forty-three studies (23 randomised controlled trials, 13 pre–post studies and 7 quasi-experimental studies) reporting on 39 interventions met the inclusion criteria. Thirteen BCTs were identified as promising for at least one outcome cluster: goal-setting (behaviour), problem-solving, behavioural contract, self-monitoring of behaviour, social support (unspecified), instruction on how to perform the behaviour, information about health consequences, information about social and environmental consequences, demonstration of the behaviour, social comparison, behavioural practice/rehearsal, generalisation of a target behaviour and addition of objects to the environment. Three BCTs (instruction on how to perform the behaviour, demonstration of the behaviour, and social comparison) and two IFs (modelling and training) were identified as promising for all outcome clusters. Conclusions Thirteen distinct BCTs are promising for use in future interventions to optimise health and well-being among older migrants. Future research should focus on the effectiveness of these BCTs (combinations) in various contexts and among different subgroups of older migrants, as well as the mechanisms through which they act. Given the scarcity of interventions in which cultural adaption has been taken into account, future behavioural change interventions should consider cultural appropriateness for various older migrant (sub)groups.

The Morphology of Coronary Artery Disease in South Asians versus White Caucasians and its Implications. Can J Cardiol 2022; 38:1570-1579. [PMID: 35568268 DOI: 10.1016/j.cjca.2022.05.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 04/27/2022] [Accepted: 05/05/2022] [Indexed: 01/09/2023] Open
Abstract
South Asians (SAs) experience a higher prevalence and earlier onset of coronary artery disease and have worse outcomes relative to White Caucasians (WCs) following invasive revascularization procedures, a mainstay of coronary artery disease (CAD) management. We sought to review the differences in the CAD pattern and risk factors between SA and WC patients and discuss their potential impact on the development of coronary disease, acute coronary syndrome and revascularization outcomes. SAs have a more diffuse pattern with multi-vessel involvement compared to WCs. However, less is known about other morphological characteristics such as calcification of atherosclerotic plaque and coronary diameter in SA populations. Despite a similar coronary calcification burden, higher non-calcified plaque composition, elevated thrombosis and inflammatory markers likely contribute to the disease pattern. While the current evidence on the role of coronary vessel size remains inconsistent, smaller coronary diameters in SAs could play a potential role in the higher disease prevalence. This is especially important given the impact of coronary artery diameter on revascularization outcomes. In conclusion, SAs have a unique CAD risk profile comprised of traditional and novel risk factors. Our findings highlight the need for additional awareness of healthcare professionals of this specific risk profile and potential therapeutic targets, as well as the need for further research in this vulnerable population.

Physical Activity Experiences of South Asian Migrant Women in Western Australia: Implications for Intervention Development. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063585. [PMID: 35329275 PMCID: PMC8955647 DOI: 10.3390/ijerph19063585] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 03/10/2022] [Accepted: 03/15/2022] [Indexed: 11/17/2022]
Abstract
The benefits of physical activity are widely recognised; however, physical activity uptake remains low in South Asian populations. South Asian migrant women face health risks as they adapt to new cultures, and these risks are often intensified through their limited participation in physical activity as one of the behaviours that promote positive health outcomes. Three focus group discussions with sixteen South Asian migrant women aged between 33 and 64 years, with a median age of 48 years and who live in Western Australia, were conducted. Thematic analysis of the transcribed qualitative data was completed to explore and uncover South Asian women’s experiences with physical activity, as well as their motivation, beliefs, attitudes, and knowledge about physical activity. Five major themes emerged after coding and analysing the data. The themes included the women’s knowledge of physical activity, their general attitudes and beliefs surrounding physical activity, the advantages and disadvantages of participation in physical activity, their experiences with physical activity, and the barriers, challenges, and facilitators surrounding physical activity. Recommendations are proposed to increase physical activity among this group to improve overall health and wellbeing and implications for intervention development are discussed.

Abstract
Objective To assess weight loss maintenance, diabetes status, mortality and morbidity 15 years after a very low calorie diet programme (VLCD) in patients with obesity. Design General practice data bases were interrogated for subjects coded for group therapy with VLCD in the 1990s. Causes of death, occurrence of vascular disease and remission or development of diabetes were ascertained from patient records and national stroke and cardiovascular disease data bases. Results 325 subjects engaged in the programme and had sufficient data for analysis. Baseline characteristics were: age 47.8±12. 8 years; body mass index (BMI) 36.1±6.8 kg/m2; 79.1% female/20.9% male; 13.5% had type 2 diabetes. After 15±4 years weight had changed from 97.9±19 kg at baseline to 100±20.8 kg. 10 with diabetes at baseline were in remission at 3 months, but only two remained in remission at 5 years. 50 new cases of type 2 diabetes and 11 of impaired fasting glucose developed during follow-up. Only 5.9% who remained healthy at follow-up had maintained >10% body weight reduction. Neither diabetes incidence nor diabetes free survival were related to percentage body weight lost during VLCD. Only baseline BMI was related to development of new impaired fasting glucose or diabetes by 15 years (p=0.007). 37 subjects had a cardiovascular event. Age (p=0.000002) and degree of weight loss after VLCD (p=0.03) were significantly associated with subsequent vascular events. Conclusion Long-term maintenance of weight loss after VLCD was rare in this single centre retrospective study 15 years later. Glucose intolerance developed in 21.4%. Lasting remission of type 2 diabetes or prevention of later glucose intolerance were not achieved. Vascular events were more frequent in those who lost most weight. Risk management during weight regain should be studied in future to assess potential for reduction in adverse cardiovascular outcomes.

Abstract
BACKGROUND South Asians, and Indians in particular, are known to have a higher incidence of premature atherosclerosis and acute coronary syndromes (ACS) with worse clinical outcomes, compared to populations with different ethnic backgrounds. However, the underlying pathobiology accounting for these differences has not been fully elucidated. METHODS ACS patients who had culprit lesion optical coherence tomography (OCT) imaging were enrolled. Culprit plaque characteristics were evaluated using OCT. RESULTS Among 1315 patients, 100 were South Asian, 1009 were East Asian, and 206 were White. South Asian patients were younger (South Asians vs. East Asians vs. Whites: 51.6 ± 13.4 vs. 65.4 ± 11.9 vs. 62.7 ± 11.7; p < 0.001) and more frequently presented with ST-segment elevation myocardial infarction (STEMI) (77.0% vs. 56.4% vs. 35.4%; p < 0.001). On OCT analysis after propensity group matching, plaque erosion was more frequent (57.0% vs. 38.0% vs. 50.0%; p = 0.003), the lipid index was significantly greater (2281.6 [1570.8-3160.6] vs. 1624.3 [940.9-2352.4] vs. 1303.8 [1090.0-1757.7]; p < 0.001), and the prevalence of layered plaque was significantly higher in the South Asian group than in the other two groups (52.0% vs. 30.0% vs. 34.0%; p = 0.003). CONCLUSIONS Compared to East Asians and Whites, South Asians with ACS were younger and more frequently presented with STEMI. Plaque erosion was the predominant pathology for ACS in South Asians and their culprit lesions had more features of plaque vulnerability.

Abstract
South Asians (i.e., people who originate from India, Pakistan, Sri Lanka, Nepal, and Bangladesh) have higher cardiovascular disease rates than other populations, and these differences persist in their offspring. Nutrition is a critical lifestyle-related factor that influences fetal development, and infant and child health in early life. In high-income countries such as Canada, nutrition-related health risks arise primarily from overnutrition, most strikingly for obesity and associated non-communicable diseases. Evidence for developmental programming during fetal life underscores the critical influence of maternal diet on fetal growth and development, backed by several birth cohort studies including the Pune Maternal Nutrition Study, the South Asian Birth Cohort Study, and the Born in Bradford Study. Gestational diabetes mellitus is a strong risk factor for type 2 diabetes, future atherosclerosis and cardiovascular disease in the mother and increases the risk of type 2 diabetes in her offspring. Non-pharmacological trials to prevent gestational diabetes are few, often not randomized, and are heterogeneous with respect to design, and outcomes have not converged upon a single optimal prevention strategy. The aim of this review is to provide an understanding of the current knowledge around perinatal nutrition and gestational diabetes among the high-risk South Asian population as well as summarize our research activities investigating the role of culturally-tailored nutrition advice to South Asian women living in high-income settings such as Canada. In this paper, we describe these qualitative and quantitative studies, both completed and underway. We conclude with a description of the design of a randomized trial of a culturally tailored personalized nutrition intervention to reduce gestational glycaemia in South Asian women living in Canada and its implications.

Abstract
Background and aims. Approximately 10-30% of the patients with typical symptoms of angina pectoris have normal angiography showing normal macrovasculature. In these patients, however, the microvascular problems should be monitored. Hence, the main aim of this study is to evaluate retinal changes in normal angiographic patients.Methods. In this descriptive cross-sectional study, 60 normal angiographic patients with typical chest pain or anginal equivalents visiting Modarres Hospital Cardiology Research Center between 2018 and 2019 were enrolled and retinal changes were determined in Labbafinejad Hospital by Optical Coherence Tomography Angiography using Foveal Avascular Zone (FAZ), Superficial Vascular Density (SVD), and Deep Vascular Density (DVD).Results. The results of this study demonstrated that FAZ was normal in all subjects, but SVD and DVD were abnormal in 45% and 8.3%, respectively. Totally, 18.5% and 66.7% showed abnormal SVD among stable angina (SA) and unstable angina (UA) cases, respectively (P < 0.001). There was no statistically significant difference between abnormal DVD in SA and UA cases (P = 0.058). Abnormal SVD was significantly more common among diabetic patients (P < 0.001), while DVD was not related to diabetes presence in the study population (P > 0.05). Moreover, abnormal SVD was more common among patients with chest pain (P = 0.036), while there was no significant difference for DVD (P = 0.371). Interestingly, abnormal ECG was associated with both abnormal DVD and SVD.Conclusions. The results of this study showed that nearly half of the patients with angina pectoris or anginal equivalents who revealed normal angiographic findings may suffer from retinal changes. Thus, retinal assessment is needed in these patients to evaluate microvascular changes.

Abstract
Myocardial injury is still a serious condition damaging the public health. Clinically, myocardial injury often leads to cardiac dysfunction and, in severe cases, death. Reperfusion of the ischemic myocardial tissues can minimize acute myocardial infarction (AMI)-induced damage. MicroRNAs are commonly recognized in diverse diseases and are often involved in the development of myocardial ischemia/reperfusion injury. However, the role of miR-431 remains unclear in myocardial injury. In this study, we investigated the underlying mechanisms of miR-431 in the cell apoptosis and autophagy of human cardiomyocytes in hypoxia/reoxygenation (H/R). H/R treatment reduced cell viability, promoted cell apoptotic rate, and down-regulated the expression of miR-431 in human cardiomyocytes. The down-regulation of miR-431 by its inhibitor reduced cell viability and induced cell apoptosis in the human cardiomyocytes. Moreover, miR-431 down-regulated the expression of autophagy-related 3 (ATG3) via targeting the 3'-untranslated region of ATG3. Up-regulated expression of ATG3 by pcDNA3.1-ATG3 reversed the protective role of the overexpression of miR-431 on cell viability and cell apoptosis in H/R-treated human cardiomyocytes. More importantly, H/R treatments promoted autophagy in the human cardiomyocytes, and this effect was greatly alleviated via miR-431-mimic transfection. Our results suggested that miR-431 overexpression attenuated the H/R-induced myocardial damage at least partly through regulating the expression of ATG3.

Association Study of Coronary Artery Disease-Associated Genome-Wide Significant SNPs with Coronary Stenosis in Pakistani Population. DISEASE MARKERS 2020; 2020:9738567. [PMID: 32685059 PMCID: PMC7336215 DOI: 10.1155/2020/9738567] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 01/17/2020] [Accepted: 01/23/2020] [Indexed: 11/19/2022]
Abstract
Genome-wide association studies (GWAS) of coronary artery disease (CAD) have revealed multiple genetic risk loci. We assessed the association of 47 genome-wide significant single-nucleotide polymorphisms (SNPs) at 43 CAD loci with coronary stenosis in a Pakistani sample comprising 663 clinically ascertained and angiographically confirmed cases. Genotypes were determined using the iPLEX Gold technology. All statistical analyses were performed using R software. Linkage disequilibrium (LD) between significant SNPs was determined using SNAP web portal, and functional annotation of SNPs was performed using the RegulomeDB and Genotype-Tissue Expression (GTEx) databases. Genotyping comparison was made between cases with severe stenosis (≥70%) and mild/minimal stenosis (<30%). Five SNPs demonstrated significant associations: three with additive genetic models PLG/rs4252120 (p = 0.0078), KIAA1462/rs2505083 (p = 0.005), and SLC22A3/rs2048327 (p = 0.045) and two with recessive models SORT1/rs602633 (p = 0.005) and UBE2Z/rs46522 (p = 0.03). PLG/rs4252120 was in LD with two functional PLG variants (rs4252126 and rs4252135), each with a RegulomeDB score of 1f. Likewise, KIAA1462/rs2505083 was in LD with a functional SNP, KIAA1462/rs3739998, having a RegulomeDB score of 2b. In the GTEx database, KIAA1462/rs2505083, SLC22A3/rs2048327, SORT1/rs602633, and UBE2Z/rs46522 SNPs were found to be expression quantitative trait loci (eQTLs) in CAD-associated tissues. In conclusion, five genome-wide significant SNPs previously reported in European GWAS were replicated in the Pakistani sample. Further association studies on larger non-European populations are needed to understand the worldwide genetic architecture of CAD.

Abstract
OBJECTIVE There are large geographical differences in implantable cardioverter defibrillator (ICD) implantation rates for reasons not completely understood. In an increasingly multiethnic population, we sought out to investigate whether ethnicity influenced ICD implantation rates. METHODS This was a retrospective, cohort study of new ICD implantation or upgrade to ICD from January 2006 to February 2019 in recipients of Caucasian or South Asian ethnicity at a single tertiary centre in the UK. Data were obtained from a routinely collected local registry. Crude rates of ICD implantation were calculated for the population of Leicestershire county and were age-standardised to the UK population using the UK National Census of 2011. RESULTS The Leicestershire population was 980 328 at the time of the Census, of which 761 403 (77.7%) were Caucasian and 155 500 (15.9%) were South Asian. Overall, 2650 ICD implantations were performed in Caucasian (91.9%) and South Asian (8.1%) patients. South Asians were less likely than Caucasians to receive an ICD (risk ratio (RR) 0.43, 95% CI 0.37 to 0.49, p<0.001) even when standardised for age (RR 0.75, 95% CI 0.74 to 0.75, p<0.001). This remained the case for primary prevention indication (age-standardised RR 0.91, 95% CI 0.90 to 0.91, p<0.001), while differences in secondary prevention ICD implants were even greater (age-standardised RR 0.49, 95% CI 0.48 to 0.50, p<0.001). CONCLUSION Despite a universal and free healthcare system, ICD implantation rates were significantly lower in the South Asian than the Caucasian population residing in the UK. Whether this is due to cultural acceptance or an unbalanced consideration is unclear.

The Burden of Atherosclerotic Cardiovascular Disease in South Asians Residing in Canada: A Reflection From the South Asian Heart Alliance. CJC Open 2019; 1:271-281. [PMID: 32159121 PMCID: PMC7063609 DOI: 10.1016/j.cjco.2019.09.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Accepted: 09/25/2019] [Indexed: 12/15/2022] Open
Abstract
South Asians (SAs), originating from the Indian subcontinent (India, Pakistan, Sri Lanka, Bangladesh, Nepal, and Bhutan), represent one quarter of the global population and are the largest visible minority in Canada. SAs experience the highest rates of coronary artery disease in Canada. Although conventional cardiovascular risk factors remain predictive in SA, the excess risk is not fully explained by these risk factors alone. Abdominal obesity, metabolic syndrome, and insulin resistance likely contribute a greater risk in SAs than in other populations. The South Asian Heart Alliance has been recently formed to investigate and recommend the best strategies for the prevention of cardiometabolic disease in SAs in Canada. This topic review represents a comprehensive overview of the magnitude of cardiovascular disease in SAs in Canada, with a review of conventional and novel risk markers in the SA population. Both primary and secondary prevention strategies are suggested and when possible, adapted specifically for the SA population. The need for SAs and their healthcare professionals to be more aware of the problem and potential solutions, along with the need for population-specific research, is highlighted.

Abstract
BACKGROUND The burden of multimorbidity is likely higher in ethnic minority populations, as most individual diseases are more prevalent in minority groups. However, information is scarce. We examined ethnic inequalities in multimorbidity, and investigated to what extent they reflect differences in socioeconomic status (SES). METHODS We included Healthy Life in an Urban Setting study participants of Dutch (N = 4582), South-Asian Surinamese (N = 3258), African Surinamese (N = 4267), Ghanaian (N = 2282), Turkish (N = 3879) and Moroccan (N = 4094) origin (aged 18-70 years). Educational level, employment status, income situation and multimorbidity were defined based on questionnaires. We described the prevalence and examined age-adjusted ethnic inequalities in multimorbidity with logistic regression analyses. To assess the contribution of SES, we added SES indicators to the age-adjusted model. RESULTS The prevalence of multimorbidity ranged from 27.1 to 53.4% in men and from 38.5 to 69.6% in women. The prevalence of multimorbidity in most ethnic minority groups was comparable to the prevalence among Dutch participants who were 1-3 decades older. After adjustment for SES, the odds of multimorbidity remained significantly higher in ethnic minority groups. For instance, age-adjusted OR for multimorbidity for the Turkish compared to the Dutch changed from 4.43 (3.84-5.13) to 2.34 (1.99-2.75) in men and from 5.35 (4.69-6.10) to 2.94 (2.54-3.41) in women after simultaneous adjustment for all SES indicators. CONCLUSIONS We found a significantly higher prevalence of multimorbidity in ethnic minority men and women compared to Dutch, and results pointed to an earlier onset of multimorbidity in ethnic minority groups. These inequalities in multimorbidity were not fully accounted for by differences in SES.

Abstract
BACKGROUND Persons of South Asian origin (SAs) are the fastest growing minority group in the United States. Culturally competent care for patients and families of SA origin necessitates an understanding of the cultural factors that affect decision-making for palliative and end-of-life care. OBJECTIVE To better understand health-care providers' perspectives on decision-making among seriously ill persons of SA origin. METHOD Data were collected in a US Midwestern city, predominantly in 2 hospital-based health-care systems along with a few interviews of private practitioners. Researchers conducted a thematic analysis of data. Transcripts were coded individually, coding disagreements resolved through discussion and themes arrived upon by consensus. RESULTS Health-care providers reported that numerous factors interact to influence decision-making among SAs. Patient-based factors include education, time spent in the United States, expectations of physician-directed care, and spiritual beliefs. Family-based factors include a norm of family-based decision-making and a complex distribution of decision-making responsibilities among family members. Provider-based factors include challenges reconciling SA and American approaches to decision-making. Community-based factors include negative attitudes and a lack of education regarding palliative care and the potential role of community support in health-care decision-making. CONCLUSIONS A rich cultural context influences health-care decision-making among seriously ill SAs. An understanding of this context will enhance providers' cultural competence and likely improve services to this growing population.

Abstract
Unequivocal evidence suggests an increased prevalence of cardiovascular disease (CVD) amongst South Asian Canadians (SACs) compared to other ethnic cohorts, due to a combination of their unique cardiometabolic profile and environmental factors. This unfavorable CVD profile is characterized by an elevated risk of dyslipidemia, high apolipoprotein B/apolipoprotein A1 ratio, hypertension, glucose intolerance, type 2 diabetes mellitus, as well as increased BMI, body fat percentage, abdominal and visceral adiposity. Despite the overwhelming evidence for the effectiveness of physical activity (PA) in circumventing the onset of CVD and in the reduction of CVD risk factors, SACs are among the most physically inactive cohorts in Canada. This relates to a set of common and unique socio-cultural barriers, such as gender, beliefs and perceptions about illness, immigration, unfavorable PA environments, and their high prevalence of debilitating chronic diseases. Several strategies to improve PA participation rates in this high-risk population have been suggested, and include the implementation of culturally sensitive PA interventions, as well as clinician training in PA prescription through workshops that emphasize knowledge translation into clinical practice. Therefore, the purpose of this mini-review is to highlight and discuss: (1) the burden of heart disease in SACs (2) the cardiovascular benefits of PA for SACs; (3) factors affecting PA participation among SACs and how they can be addressed; (4) the impact of culturally sensitive PA prescription on CVD prevention; (5) barriers to culture-specific PA prescription by clinicians, and strategies to improve its use and impact.

The HELIUS study. Int J Hyg Environ Health 2018; 222:221-229. [PMID: 30316691 DOI: 10.1016/j.ijheh.2018.10.002] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 10/05/2018] [Accepted: 10/06/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Although there is growing evidence that depressed mood is affected by road traffic noise, previous results are not fully consistent. Furthermore, to our knowledge, no previous research has assessed ethnic and socioeconomic inequalities in the association of noise exposure with depressed mood. OBJECTIVE To investigate the association between road traffic noise with depressed mood and to determine to what extent this association varies between ethnic and socioeconomic groups. METHOD We investigated cross-sectional data collected between 2011 and 2015 from 23,293 HELIUS participants (18-70 years) living in Amsterdam. Our study included five different ethnic groups (Dutch, Moroccan, Turkish, South-Asian Surinamese and African Surinamese origin). All respondents were linked by their residential postal code to geographic data on road traffic noise levels (24 h noise average in A-weighted decibels [dB(A)]). Noise was categorized into five categories (45-54 dB(A), 55-59 dB(A), 60-64 dB(A), 65-69 dB(A), ≥70 dB(A)) and high noise exposure was defined as noise levels ≥65 dB(A). Depressed mood was defined as a sum-score of ≥10 on the 9-item Patient Health Questionnaire (PHQ-9). Logistic regression was performed to assess the relationship between road traffic noise and depressed mood. Multilevel analyses were used to take into account the clustering of observations within neighbourhoods. Lastly, logistic regression analyses were applied to estimate relative risks for depressed mood per different ethnic and socioeconomic groups exposed to high noise exposure ≥65 dB(A) compared to <65 dB(A). Analyses were adjusted for individual- and neighbourhood-level confounders. RESULTS Exposure to ≥70 dB(A) compared to the reference group of 45-54 dB(A) showed a significant positive association with depressed mood (OR: 1.65, 95% CI 1.10, 2.48). Participants exposed to 60-64 dB(A) showed a significantly lower odds ratio of 0.82 (95% CI 0.70, 0.97) compared to the reference group. We observed no differences between ethnic groups in the association of high noise exposure ≥65 dB(A) with depressed mood. Regarding socioeconomic groups, results were different for the medium-low educated group and unemployed group only. CONCLUSION This study adds new evidence regarding a positive association between high road traffic noise exposure and depressed mood in residential settings. We found no evidence for systematic ethnic or socioeconomic inequalities regarding this association.

Abstract
Dietary acculturation (adopting the eating patterns/practices of the host environment) of individuals who relocate to another country could be a risk factor for diet-related chronic diseases. A reliable and validated measure for the assessment of dietary acculturation may facilitate understanding of the relationship between dietary acculturation and diet-related chronic diseases in various nonnative populations. We aimed to determine the reliability and validity of a culturally sensitive Asian Indian Dietary Acculturation Measure (AIDAM) for Asian Indians. A cross-sectional survey was administered via Qualtrics Research Suite to 191 Asian Indian adults in the United States. The web survey consisted of AIDAM, a food frequency questionnaire consisting of Asian Indian (AI-FFQ) and non-Indian (NI-FFQ) foods and participant sociodemographic questions. Reliability and validity were examined through a polytomous Rasch model. Except for one item that was excluded due to misfit, 50 items were stable. The root mean square error was .08 for all the items, and the item and person reliabilities were .98 and .88, respectively. AIDAM was positively related to NI-FFQ ( r = .265) and negatively related to AI-FFQ ( r = -.432) based on correlations and linear regressions ( p < .001). Our preliminary analysis showed the AIDAM to have good reliability and validity when tested with a sample of Asian Indians in the United States. Further large studies with Asian Indians using AIDAM are needed to support our findings. This tool can be used by health professionals and researchers to determine the level of dietary acculturation as well as diet quality implications when assessing risk for diet-related diseases.

Abstract
The knowledge of ethnic-specific health needs is now essential to design effective health services and population-based prevention strategies. However, data on migrant populations living in Southern Europe are limited. The study is designed to investigate ethnic inequalities in hospitalization for acute myocardial infarction (AMI) in the Veneto region (Italy). Hospital admissions for AMI in Veneto for the whole resident population aged 20-59 years during 2008-2013 were studied. Age and gender-specific AMI hospitalization rates for immigrant groups (classified by country of origin according to the United Nations geoscheme) and Italians were calculated. The indirect standardization method was used to estimate standardized hospitalization ratios (SHR) for each immigrant group, with rates of Italian residents as a reference. Overall, 8200 AMI events were retrieved, 648 among immigrants. The highest risk of AMI is seen in South Asians males (SHR 4.2, 95% CI 3.6-4.9) and females (SHR 2.5, 95% CI 1.4-4.5). AMI rates in South Asian males sharply increase in the 30-39 years age class. Other immigrant subgroups (Eastern Europe, North Africa, Sub-Saharan Africa, other Asian countries, Central-South America, high-income countries) displayed age- and gender-adjusted hospitalization rates similar to the native population. Present findings stress the urgent need for implementation of ethnic-specific health policies in Italy. The awareness about the high cardiovascular risk in subjects from South Asia must be increased among general practitioners and immigrant communities.

Abstract
ObjectivesTo investigate ethnic differences in susceptibility to bradycardias in South Asian and white European patients in the UK by determining rates of permanent pacemaker (PPM) implantation for sinus node dysfunction (SND) and atrioventricular block (AVB) in each ethnic group.MethodsWe carried out a retrospective cohort study into new PPM implantation during the period from 1 May 2006 to 31 March 2014, in patients of South Asian and Caucasian ethnicity resident in Leicestershire, UK. Numbers of individuals at risk in each ethnic group were derived from UK National Census data of 2011. Crude, and age-standardised incidence rates and risk ratios per 1000 population of PPM implantation were calculated for Caucasians and South Asians.ResultsDuring the study period, 4883 individuals from the Leicestershire population of 980 328 underwent PPM implantation, a cumulative implantation rate of 4.98/1000 population. The population cumulative PPM implantation rate for SND was 1.74/1000, AVB 2.83/1000 and other indications 0.38/1000 population. The crude incidence in Caucasians (6.15/1000 population) was higher than in South Asians (1.07/1000 population) and remained higher after age standardisation (5.60/1000 vs 2.03/1000, P<0.001). The age-standardised cumulative PPM implantation rates were lower in South Asians for both SND (0.53/1000 in South Asians; 1.97/1000 in Caucasians, P<0.001) and AVB (1.30/1000 in South Asians; 3.17/1000 in Caucasians, P<0.001). Standardised risk ratios (95% CI) for PPM implantation in South Asians compared with Caucasians for all pacing indications, SND and AVB were 0.36 (95% CI 0.36 to 0.37), 0.27 (95% CI 0.27 to 0.28) and 0.41 (95% CI 0.41 to 0.42), respectively.ConclusionsRates of PPM implantation are lower in South Asians residing in the UK, compared with Caucasians. This observation raises the possibility of lower inherent susceptibility to bradycardias in South Asians compared with Caucasians. Studies aimed at identifying underlying mechanisms, including possible genetic differences, are warranted.

Abstract
South Asians have the highest rates of premature atherosclerotic cardiovascular disease amongst all ethnic groups in the world; however this risk cannot be fully explained by traditional risk factors. Participants from the Mediators of Atherosclerosis in South Asians Living in America Study were included in this cross-sectional analysis. The purpose of this study was to investigate the association of psychosocial factors (including anger, anxiety, depressive symptoms, current and chronic stress, and everyday hassles) with carotid intima-media thickness (CIMT). Three multivariate models were examined to evaluate the association between the psychosocial factors and CIMT. Findings suggest that the impact of psychosocial factors on subclinical atherosclerosis is differential for South Asian men and women. For men, anxiety and depression were associated; while for women, stress was associated with common carotid intima media thickness, independent of traditional CVD risk factors, diet and physical activity.

Abstract
PURPOSE Ethnic minority groups usually have a more unfavourable disease risk profile than the host population. In Europe, ethnic inequalities in health have been observed in relatively small studies, with limited possibilities to explore underlying causes. The aim of the Healthy Life in an Urban Setting (HELIUS) study is to investigate the causes of (the unequal burden of) diseases across ethnic groups, focusing on three disease categories: cardiovascular diseases, mental health and infectious diseases. PARTICIPANTS The HELIUS study is a prospective cohort study among six large ethnic groups living in Amsterdam, the Netherlands. Between 2011 and 2015, a total 24 789 participants (aged 18-70 years) were included at baseline. Similar-sized samples of individuals of Dutch, African Surinamese, South-Asian Surinamese, Ghanaian, Turkish and Moroccan origin were included. Participants filled in an extensive questionnaire and underwent a physical examination that included the collection of biological samples (biobank). FINDINGS TO DATE Data on physical, behavioural, psychosocial and biological risk factors, and also ethnicity-specific characteristics (eg, culture, migration history, ethnic identity, socioeconomic factors and discrimination) were collected, as were measures of health outcomes (cardiovascular, mental health and infections). The first results have confirmed large inequalities in health between ethnic groups, such as diabetes and depressive symptoms, and also early markers of disease such as arterial wave reflection and chronic kidney disease, which can only just partially be explained by inequalities in traditional risk factors, such as obesity and socioeconomic status. In addition, the first results provided important clues for targeting prevention and healthcare. FUTURE PLANS HELIUS will be used for further research on the underlying causes of ethnic differences in health. Follow-up data will be obtained by repeated measurements and by linkages with existing registries (eg, hospital data, pharmacy data and insurance data).

Abstract
OBJECTIVE To evaluate the quality of contemporary secondary prevention of cardiovascular disease (CVD), and the differences between six ethnic groups in a large, observational cohort. DESIGN We included participants with a self-reported history of CVD from the HEalthy LIfe in an Urban Setting (HELIUS) study, which investigates inequalities in health between six ethnic groups living in Amsterdam, the Netherlands. We quantified the proportions of patients who were at the preventive treatment goal according to the guidelines of the European Society of Cardiology for six risk factors: hypertension, dyslipidaemia, smoking, overweight, physical inactivity and diabetes mellitus, and the use preventive medication. RESULTS Of 22,165 participants, 1163 (5%) reported a history of CVD. Mean age was 54 years. Overall, 69% had a systolic blood pressure of <140 mm Hg, and 42% had a low-density lipoprotein (LDL) cholesterol of <2.5 mmol/l. Non-smoking was found in 67%. Body mass index (BMI) <25 kg/m2 was found in 24%, and 54% reported adequate physical activity. The mean number of risk factors per patient was three (±1.1) out of six, and only 2% had all risk factors on target. Across the ethnic groups, non-smoking was more prevalent in the Ghanaian and Moroccan groups than in the Dutch (p < 0.001 and p = 0.001, respectively); BMI <25 kg/m2 and adequate physical activity were less prevalent among all ethnic minority groups compared with the Dutch group. CONCLUSION We found large treatment gaps in secondary prevention of CVD. Ethnic differences in risk factors were found; however, strategies to improve overall risk factor management may be mandated before designing ethnic-specific strategies.

Abstract
BACKGROUND Unequivocally, cardiac rehabilitation (CR) in patients with established cardiovascular disease improves survival. However, its effect on higher-risk ethnic groups has not been explored. Accordingly, we evaluated the effect of CR on South Asian (SA) compared with European Canadians with coronary artery disease (CAD). METHODS Using the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) registry, 26,167 patients from Edmonton, Alberta who received coronary angiography with documented CAD were reviewed (January 2002 to March 2012). After excluding Chinese patients, 1027 SA patients were compared with 11,992 European Canadian patients using validated surname algorithms. Adjustment was performed using a Cox proportional hazard model. RESULTS Of the SA cohort, 50.6% attended CR, compared with 43.0% of the European Canadian cohort (P < 0.001). After adjustment, CR was associated with long-term survival irrespective of ethnic group (total study population: hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.52-0.63; P < 0.001; SA population: HR, 0.63; 95% CI, 0.40-0.99; P = 0.045; European population: HR, 0.57; 95% CI, 0.52-0.63; P < 0.001). When comparing SA vs European Canadians attending CR, improved survival was observed in SA patients (HR, 0.58; 95% CI, 0.40-0.85; P < 0.001). This benefit appeared limited to SA patients who completed CR (complete CR: HR, 0.37; 95% CI, 0.17-0.85; P = 0.02; incomplete CR: HR, 0.78; 95% CI, 0.45-1.35; P = 0.38). CONCLUSIONS Overall, referral rates to CR remains low but attendance appears higher in SA patients. Among those who attended CR, there is a strong association with improved survival irrespective of ethnic status. In SA patients with CAD, attendance and completion of CR should be strongly endorsed because of its incremental benefit.

Abstract
BACKGROUND Coronary artery disease is a major public health problem affecting both developed and developing countries. Acute coronary syndromes include unstable angina and myocardial infarction with or without ST-segment elevation (electrocardiogram sector is higher than baseline). Ventricular arrhythmia after myocardial infarction is associated with high risk of mortality. The evidence is out of date, and considerable uncertainty remains about the effects of prophylactic use of lidocaine on all-cause mortality, in particular, in patients with suspected myocardial infarction. OBJECTIVES To determine the clinical effectiveness and safety of prophylactic lidocaine in preventing death among people with myocardial infarction. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 3), MEDLINE Ovid (1946 to 13 April 2015), EMBASE (1947 to 13 April 2015) and Latin American Caribbean Health Sciences Literature (LILACS) (1986 to 13 April 2015). We also searched Web of Science (1970 to 13 April 2013) and handsearched the reference lists of included papers. We applied no language restriction in the search. SELECTION CRITERIA We included randomised controlled trials assessing the effects of prophylactic lidocaine for myocardial infarction. We considered all-cause mortality, cardiac mortality and overall survival at 30 days after myocardial infarction as primary outcomes. DATA COLLECTION AND ANALYSIS We performed study selection, risk of bias assessment and data extraction in duplicate. We estimated risk ratios (RRs) for dichotomous outcomes and measured statistical heterogeneity using I(2). We used a random-effects model and conducted trial sequential analysis. MAIN RESULTS We identified 37 randomised controlled trials involving 11,948 participants. These trials compared lidocaine versus placebo or no intervention, disopyramide, mexiletine, tocainide, propafenone, amiodarone, dimethylammonium chloride, aprindine and pirmenol. Overall, trials were underpowered and had high risk of bias. Ninety-seven per cent of trials (36/37) were conducted without an a priori sample size estimation. Ten trials were sponsored by the pharmaceutical industry. Trials were conducted in 17 countries, and intravenous intervention was the most frequent route of administration.In trials involving participants with proven or non-proven acute myocardial infarction, lidocaine versus placebo or no intervention showed no significant differences regarding all-cause mortality (213/5879 (3.62%) vs 199/5848 (3.40%); RR 1.02, 95% CI 0.82 to 1.27; participants = 11727; studies = 18; I(2) = 15%); low-quality evidence), cardiac mortality (69/4184 (1.65%) vs 62/4093 (1.51%); RR 1.03, 95% CI 0.70 to 1.50; participants = 8277; studies = 12; I(2) = 12%; low-quality evidence) and prophylaxis of ventricular fibrillation (76/5128 (1.48%) vs 103/4987 (2.01%); RR 0.78, 95% CI 0.55 to 1.12; participants = 10115; studies = 16; I(2) = 18%; low-quality evidence). In terms of sinus bradycardia, lidocaine effect is imprecise compared with effects of placebo or no intervention (55/1346 (4.08%) vs 49/1203 (4.07%); RR 1.09, 95% CI 0.66 to 1.80; participants = 2549; studies = 8; I(2) = 21%; very low-quality evidence). In trials involving only participants with proven acute myocardial infarction, lidocaine versus placebo or no intervention showed no significant differences in all-cause mortality (148/2747 (5.39%) vs 135/2506 (5.39%); RR 1.01, 95% CI 0.79 to 1.30; participants = 5253; studies = 16; I(2) = 9%; low-quality evidence). No significant differences were noted between lidocaine and any other antiarrhythmic drug in terms of all-cause mortality and ventricular fibrillation. Data on overall survival 30 days after myocardial infarction were not reported. Lidocaine compared with placebo or no intervention increased risk of asystole (35/3393 (1.03%) vs 14/3443 (0.41%); RR 2.32, 95% CI 1.26 to 4.26; participants = 6826; studies = 4; I(2) = 0%; very low-quality evidence) and dizziness/drowsiness (74/1259 (5.88%) vs 16/1274 (1.26%); RR 3.85, 95% CI 2.29 to 6.47; participants = 2533; studies = 6; I(2) = 0%; low-quality evidence). Overall, safety data were poorly reported and adverse events may have been underestimated. Trial sequential analyses suggest that additional trials may not be needed for reliable conclusions to be drawn regarding these outcomes. AUTHORS' CONCLUSIONS This Cochrane review found evidence of low quality to suggest that prophylactic lidocaine has very little or no effect on mortality or ventricular fibrillation in people with acute myocardial infarction. The safety profile is unclear. This conclusion is based on randomised controlled trials with high risk of bias. However (disregarding the risk of bias), trial sequential analysis suggests that additional trials may not be needed to disprove an intervention effect of 20% relative risk reduction. Smaller risk reductions might require additional higher trials.

Abstract
Cardiovascular disease (CVD) represents a significant cause of global mortality and morbidity. South Asians (SAs) have a particularly high burden of coronary artery disease (CAD). This review describes current literature regarding the prevalence, incidence, etiology, and prognosis of CVD in SA migrants to high-income nations. We conducted a narrative review of CVD in the SA diaspora through a search of MEDLINE and PubMed. We included observational studies, randomized clinical trials, nonsystematic reviews, systematic reviews, and meta-analyses written in English. Of 15,231 articles identified, 827 articles were screened and 124 formed the basis for review. SA migrants have a 1.5-2 times greater prevalence of CAD than age- and sex-adjusted Europids. Increased abdominal obesity and body fat and increased burden of type 2 diabetes mellitus and dyslipidemia appear to be primary drivers of the excess CAD burden in SAs. Sedentary lifestyle and changes in diet after immigration are important contributors to weight gain and adiposity. Early life factors, physical activity patterns and, in some cases, reduced adherence to medical therapy may contribute to increased CVD risks in SAs. Novel biomarkers like leptin and adipokines may show distinct patterns in SAs and provide insights into cardiometabolic risk determinants. In conclusion, SAs have distinct CVD risk predispositions, with a complex relationship to cultural, innate, and acquired factors. Although CVD risk factor management and treatment among SAs is improving, opportunities exist for further advances.

Abstract
Objectives To quantify and compare the association between the World Health Organizations’ Asian-specific trigger points for public health action [‘increased risk’: body mass index (BMI) ≥23 kg/m2, and; ‘high risk’: BMI ≥27.5 kg/m2] with self-reported cardiovascular-related conditions in Asian-Canadian sub-groups. Methods Six cycles of the Canadian Community Health Survey (2001–2009) were pooled to examine BMI and health in Asian sub-groups (South Asians, Chinese, Filipino, Southeast Asians, Arabs, West Asians, Japanese and Korean; N = 18 794 participants, ages 18–64 y). Multivariable logistic regression, adjusting for demographic, lifestyle characteristics and acculturation measures, was used to estimate the odds of cardiovascular-related health (high blood pressure, heart disease, diabetes, ‘at least one cardiometabolic condition’) outcomes across all eight Asian sub-groups. Results Compared to South Asians (OR = 1.00), Filipinos had higher odds of having ‘at least one cardiometabolic condition’ (OR = 1.29, 95% CI: 1.04–1.62), whereas Chinese (0.63, 0.474–0.9) and Arab-Canadians had lower odds (0.38, 0.28–0.51). In ethnic-specific analyses (with ‘acceptable’ risk weight as the referent), ‘increased’ and ‘high’ risk weight categories were the most highly associated with ‘at least one cardiometabolic condition’ in Chinese (‘increased’: 3.6, 2.34–5.63; ‘high’: 8.9, 3.6–22.01). Compared to normal weight South Asians, being in the ‘high’ risk weight category in all but the Southeast Asian, Arab, and Japanese ethnic groups was associated with approximately 3-times the likelihood of having ‘at least one cardiometabolic condition’. Conclusion Differences in the association between obesity and cardiometabolic health risks were seen among Asian sub-groups in Canada. The use of WHO’s lowered Asian-specific BMI cut-offs identified obesity-related risks in South Asian, Filipino and Chinese sub-groups that would have been masked by traditional BMI categories. These findings have implications for public health messaging, especially for ethnic groups at higher odds of obesity-related health risks.

Abstract
BACKGROUND The South Asian and Chinese populations represent a significant portion of the population of Ontario; however, little is known about the burden of respiratory OBJECTIVE: To investigate the prevalence of asthma and the associated health care burden among South Asian and Chinese populations living in Ontario. METHODS Using administrative health data for Ontario, the authors identified individuals of South Asian and Chinese descent using a validated surname algorithm and compared the prevalence of asthma in these groups with the general population using an established asthma case definition for the period 2002 to 2010. Also compared were the rates of asthma-specific emergency department visits and hospitalizations among the ethnic groups. RESULTS In 2010, the prevalence of asthma in South Asians residing in Ontario was similar to that of the general population (12.1% versus 12.4%), and was increasing at a faster rate than in the general population (0.51%⁄year versus 0.34%⁄year). Compared with the general population, the South Asian population had fewer emergency department visits for asthma, whereas the asthma-related hospitalization rate was greatest among the South Asian population (0.45 per 100 person-years). The Chinese population had the lowest asthma prevalence and associated health care use. CONCLUSION The burden of asthma among South Asians in Ontario is increasing and warrants further investigation to determine the reasons for this rise.

Abstract
People of South Asian (SA) descent are particularly susceptible to acute coronary syndromes (ACS). Yet, little information exists regarding their overall prognosis. The purpose of this study was to compare short- and long-term clinical outcomes of SA and European Canadians admitted with an ACS. Using the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease registry, 63,393 patients with ACS were reviewed (January 1999 to March 2012). After excluding Chinese patients, 1,825 SAs were compared with 60,791 European Canadians. Both groups were propensity matched, and outcomes were compared. Adjustment was performed using a 3:1 propensity matching technique. Adjusted 30-day and 1-year mortality rates were similar between SA and European patients with ACS (2.6% vs 2.7%, p = 0.93; 5.0% vs 4.8%, respectively, p = 0.75). Repeat angiography did not differ (9.9% vs 9.2%, p = 0.35), yet repeat revascularization within 1 year was greater in SA patients (9.8% vs 7.6%, p <0.01). Improved long-term survival (median 64 months, interquartile range 66 months) was noted with SA patients (hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.71 to 0.95). In particular, long-term survival was observed in SA patients receiving coronary artery bypass grafting (HR 0.75, 95% CI 0.52 to 1.08) and percutaneous coronary intervention (HR 0.75, 95% CI 0.59 to 0.96). In conclusion, SA patients treated with revascularization appear to have improved long-term survival after ACS, compared with European Canadians. As such, clinicians should be cognitive of ethnic-based outcomes when determining therapeutic strategies in patient management.

Abstract
South Asians (SAs), in their countries or after migration, are at high risk of coronary artery disease (CAD) and mortality compared to other ethnic groups. It has been shown that >90% of CAD global risk could be attributed to 9 modifiable risk factors (RFs) worldwide. However, these conventional RFs may not fully explain this high risk of CAD among SAs. Therefore, attention has been directed toward nonconventional RFs. In this narrative review, we evaluate the conventional and emerging cardiovascular RFs characterizing SAs. These factors may explain the high morbidity and mortality among SAs. Further prospective studies are urgently needed to set algorithms for the optimal management of these RFs in high-risk populations like SAs.

Abstract
BACKGROUND South Asians represent about 3% of the Canadian population and have a higher burden of certain cardiovascular risk factors and cardiovascular disease (CVD) compared with white people. The objective of this study was to review the literature to compare cardiovascular risk factors and disease management practices among adult South Asian and white Canadians. METHODS We searched MEDLINE, Embase, Cochrane and Cumulative Index to Nursing and Allied Health Literature databases from their inception through Feb. 17, 2014 and the reference lists of the selected articles. English-language studies of interventions and observational studies of biological mechanisms underlying CVD risk in South Asians conducted in Canada were eligible for inclusion. Where appropriate, we used random-effects meta-analyses to integrate results comparing the CVD risk profiles of South Asian and white Canadians. RESULTS We included 50 articles (n = 5 805 313 individuals) in this review. Compared with white Canadians, South Asian Canadians had a higher prevalence and incidence of CVD, an increased prevalence of diabetes (odds ratio [OR] 2.25, 95% confidence interval [CI] 1.81 to 2.80, p < 0.001) and hypertension (OR 1.11, 95% CI 1.02 to 1.22, p = 0.02), lower high-density lipoprotein cholesterol levels (mean difference -0.19 mmol/L, 95% CI -0.25 to -0.13 mmol/L, p < 0.001) and a higher percentage of body fat (men: absolute mean difference 3.23%, 95% CI 0.83% to 5.62%, p = 0.008; women: absolute mean difference 4.09%, 95% CI 3.46% to 4.72%, p < 0.001). South Asian people are also more sedentary, consume higher levels of carbohydrates and are less likely to smoke tobacco (OR 0.38, 95% CI 0.24 to 0.60, p < 0.001]) than white Canadians. No differences in access to diagnostic tests, outcomes following cardiovascular surgery or use of cardiac rehabilitation programs were apparent. INTERPRETATION Compared with white people, South Asian people living in Canada have a higher prevalence and incidence of CVD and possess a unique cardiovascular risk profile.

Abstract
BACKGROUND No studies have comprehensively examined the prevalence of dyslipidemia, a major risk factor for cardiovascular disease, among diverse racial/ethnic minority groups. The primary aim of this study was to identify racial/ethnic differences in dyslipidemia among minorities including Asian Americans (Asian Indian, Chinese, Filipino, Japanese, Korean, or Vietnamese), Mexican Americans, and blacks compared with non-Hispanic whites. METHODS AND RESULTS Using a 3-year cross section (2008-2011), we identified 169 430 active primary care patients (35 years or older) from an outpatient healthcare organization in northern California. Age-standardized prevalence rates were calculated for 3 dyslipidemia subtypes: high triglycerides (fasting laboratory value ≥150 mg/dL), low levels of high-density lipoprotein cholesterol (fasting laboratory value <40 mg/dL [men] and <50 mg/dL [women]), and high levels of low-density lipoprotein cholesterol (fasting laboratory value ≥130 mg/dL or taking low-density lipoprotein-lowering agents). Odds ratios were calculated by multivariable logistic regression, with adjustment for patient characteristics (age, measured body mass index, smoking). Compared with non-Hispanic whites, every minority subgroup had an increased prevalence of high triglycerides except blacks. Most minority groups had an increased prevalence of low high-density lipoprotein cholesterol, except for Japanese and blacks. The prevalence of high low-density lipoprotein cholesterol was increased among Asian Indians, Filipinos, Japanese, and Vietnamese compared with non-Hispanic whites. CONCLUSIONS Minority groups, except for blacks, were more likely to have high triglyceride/low high-density lipoprotein cholesterol dyslipidemia. Further research is needed to determine how racial/ethnic differences in dyslipidemia affect racial/ethnic differences in cardiovascular disease rates.

Abstract
BACKGROUND Populations in Europe are becoming increasingly ethnically diverse, and health risks differ between ethnic groups. The aim of the HELIUS (HEalthy LIfe in an Urban Setting) study is to unravel the mechanisms underlying the impact of ethnicity on communicable and non-communicable diseases. METHODS/DESIGN HELIUS is a large-scale prospective cohort study being carried out in Amsterdam, the Netherlands. The sample is made up of Amsterdam residents of Surinamese (with Afro-Caribbean Surinamese and South Asian-Surinamese as the main ethnic groups), Turkish, Moroccan, Ghanaian, and ethnic Dutch origin. HELIUS focuses on three disease categories: cardiovascular disease (including diabetes), mental health (depressive disorders and substance use disorders), and infectious diseases. The explanatory mechanisms being studied include genetic profile, culture, migration history, ethnic identity, socio-economic factors and discrimination. These might affect disease risks through specific risk factors including health-related behaviour and living and working conditions. Every five years, participants complete a standardized questionnaire and undergo a medical examination. Biological samples are obtained for diagnostic tests and storage. Participants' data are linked to morbidity and mortality registries. The aim is to recruit a minimum of 5,000 respondents per ethnic group, to a total of 30,000 participants. DISCUSSION This paper describes the rationale, conceptual framework, and design and methods of the HELIUS study. HELIUS will contribute to an understanding of inequalities in health between ethnic groups and the mechanisms that link ethnicity to health in Europe.

Feasibility of community-based screening for cardiovascular disease risk in an ethnic community: the South Asian Cardiovascular Health Assessment and Management Program (SA-CHAMP). BMC Public Health 2013; 13:160. [PMID: 23432996 PMCID: PMC3614427 DOI: 10.1186/1471-2458-13-160] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2012] [Accepted: 02/19/2013] [Indexed: 01/05/2023] Open
Abstract
Background South Asian Canadians experience disproportionately high rates of cardiovascular disease (CVD). The goal of this qualitative study was to determine the feasibility of implementing a sustainable, culturally adapted, community-based CVD risk factor screening program for this population. Methods South Asians (≥ 45 years) in Calgary, Alberta underwent opportunistic cardiovascular risk factor screening by lay trained volunteers at local religious facilities. Those with elevated blood pressure (BP) or ≥ 1 risk factor underwent point of care cholesterol testing, 10-year CVD risk calculation, counseling, and referral to family physicians and local culturally tailored chronic disease management (CDM) programs. Participants were invited for re-screening and were surveyed about health system follow-up, satisfaction with the program and suggestions for improvement. Changes in risk factors from baseline were estimated using McNemar’s test (proportions) and paired t-tests (continuous measures). Results Baseline assessment was completed for 238 participants (median age 64 years, 51% female). Mean TC, HDL and TC/HDL were 5.41 mmol/L, 1.12 mmol/L and 4.7, respectively. Mean systolic and diastolic blood pressures (mmHg) were 129 and 75 respectively. Blood pressure and TC/HDL ratios exceeded recommended targets in 36% and 58%, respectively, and 76% were at high risk for CVD. Ninety-nine participants (47% female) attended re-screening. 82% had accessed health care providers, 22% reported medication changes and 3.5% had attended the CDM programs. While BP remained unchanged, TC and TC/HDL decreased and HDL increased significantly (mean differences: -0.52 mmol/L, -1.04 and +0.07 mmol/L, respectively). Participants were very satisfied (80%) or satisfied (20%) with the project. Participants suggested screening sessions and CDM programs be more accessible by: delivering evening or weekends programs at more sites, providing transportation, offering multilingual programs/translation assistance, reducing screening wait times and increasing numbers of project staff. Conclusions SA-CHAMP demonstrated the feasibility and value of implementing a lay volunteer–led, culturally adapted, sustainable community-based CVD risk factor screening program in South Asian places of worship in Calgary, Alberta, Canada. Subsequent screening and CDM programs were refined based on the learnings from this study. Further research is needed to determine physician and patient factors associated with uptake of and adherence to risk reduction strategies.

Abstract
South Asians have a higher risk for coronary artery disease (CAD) due to both pathophysiological and life course-related risk factors. We performed a literature search and used qualitative synthesis to present evidence for CAD risk factors among South Asians. A large proportion of the higher risk of South Asians for CAD can be explained by conventional risk factors. However, several conditioning factors such as education, socioeconomic status, and fetal programming, and early life influences may contribute to excess CAD risk in South Asians, suggesting the need for a life course approach. Evidence on unconventional risk factors is provocative but comes from small studies. Large-scale, well-designed epidemiological studies are needed for an in-depth understanding of the CAD risk among South Asians.

Abstract
The most important goal in the treatment of patients with diabetes is to lower the risk of long-term diabetes complications. Hyperglycaemia is the most important risk factor for microvascular complications in diabetes, but, in addition to hyperglycaemia, several other risk factors, particularly dyslipidaemia, elevated blood pressure and smoking, also determine the risk of macrovascular complications. In this review, we present evidence from longitudinal population-based studies that hyperglycaemia is an important risk factor for long-term complications of diabetes and discuss the results from clinical trials of the effects of the treatment of hyperglycaemia on the prevention of long-term micro- and macrovascular complications in type 1 and type 2 diabetes. An HbA(1c) target of <7.0% for the treatment of diabetes is generally accepted on the basis of evidence from several trials, whereas a target of <6.5% may be reasonable for patients with a short duration of type 2 diabetes and without extensive atherosclerosis.

Abstract
Individuals of South Asian descent have a high prevalence of comorbidities that are risk factors for the development of heart failure (HF), including diabetes mellitus and metabolic syndrome. However, little is known about the prevalence of HF, its management and prognosis for this population compared to Caucasians. Therefore, a literature review relating to the nature, outcome and treatment of HF in South Asian patients compared to Caucasians was conducted. It was anticipated that collating existing studies in this manner would be useful for guiding professionals in managing HF within this ethnic group, given that to achieve optimal care, regimens need to take into account cultural differences that may impact on adherence. Reviewed literature showed that South Asians with HF were more likely to be younger and have diabetes and hypertension. These papers also implied that outcomes for South Asians with HF were similar or even better than for Caucasians. The review highlighted the under-representation of South Asians in HF trials, meaning that evidence-based recommendations tailored to this specific population are limited. This is an important consideration because ethnic differences in response to medication have been reported; it cannot be assumed that treatments shown to work for Caucasians will be efficacious for those from minority ethnic groups.

Abstract
OBJECTIVE This study investigated South Asians' explanatory models (EM) of CHD and compared them to the biomedical model as part of an effort to inform the development of culturally targeted CHD prevention messages. METHODS We conducted in-depth, semi-structured interviews in English, Hindi and Urdu with 75 respondents from a federally qualified health center and at a community center for South Asian immigrants in Chicago, Illinois. RESULTS While EMs of CHD included risk factors from the biomedical model, they also included psychosocial and spiritual risk factors. Respondents emphasized that stress causes CHD and suggested that CHD was caused by sudden or inexplicable factors. Few respondents discussed cholesterol, blood pressure, or diabetes as part of CHD prevention. Women and those with lower education had low perceptions of being at-risk for CHD. CONCLUSION South Asians' EMs of CHD encompassed the biomedical model; however, EMs also included psychosocial and spiritual factors. PRACTICE IMPLICATIONS Clinicians and health educators should be aware that South Asian individual's EM of CHD may include psychosocial and spiritual factors which can affect CHD prevention behaviors.

Abstract
OBJECTIVES To compare the prevalence and management of cardiovascular risk factors (CVRFs) between immigrant groups and Swiss nationals. METHODS The Swiss Health Surveys (SHS, N = 49,245) and CoLaus study (N = 6,710) were used. Immigrant groups from France, Germany, Italy, Portugal, Spain, former Yugoslavia, other European and other countries were defined. RESULTS Immigrants from Italy, France, Portugal, Spain and former Yugoslavia presented a higher prevalence of smoking than Swiss nationals. Immigrants reported less hypertension than Swiss nationals, but the differences were reduced when blood pressure measurements were used. The prevalence of dyslipidaemia was similar between immigrants and Swiss nationals in the SHS. When eligibility for statin treatment was assessed, immigrants from Italy were more frequently eligible than Swiss nationals. Immigrants from former Yugoslavia presented a lower prevalence of diabetes in the SHS, but a higher prevalence in the CoLaus study. Most differences between immigrant groups and Swiss nationals disappeared after adjusting for age, leisure-time physical activity, being overweight/obesity and education. CONCLUSIONS Most CVRFs are unevenly distributed among immigrant groups in Switzerland, but these differences are due to disparities in age, leisure-time physical activity, being overweight/obesity and education.

Abstract
BACKGROUND People of South Asian (SA) ancestry are susceptible to coronary artery disease (CAD). Although studies suggest that SA with CAD has a worse prognosis compared with Europeans, it is unknown whether corresponding differences in functional status and quality-of-life (QOL) measures exist. Accordingly, we compared symptoms, function, and QOL in SA and European Canadians with CAD using the Seattle Angina Questionnaire (SAQ). METHODS Using the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease, an outcomes registry that captures patients undergoing cardiac catheterization in Alberta, Canada, we identified 635 SA and 18,934 European patients with angiographic CAD from January 1995 to December 2006 who reported health status outcomes using the SAQ at 1 year after the index catheterization. To obtain comparable clinical variables among SA and Europeans, we used a propensity score-matching technique. RESULTS One-year adjusted mean (SD) scores were significantly lower in SA compared with European Canadians for most SAQ domains: exertional capacity (75 [23] vs 80 [23], P = .011), anginal stability (77 [28] vs 77 [27], P = .627), anginal frequency (86 [23] vs 88 [20], P < .001), treatment satisfaction (86 [19] vs 89 [16], P < .001), and SAQ QOL (71 [24] vs 76 [21], P < .001). These results could not be accounted for by differences in baseline QOL scores or changes in health status from baseline to 1 year. CONCLUSION South Asian Canadians with established CAD have significantly worse health status outcomes at 1 year after angiography compared with European Canadians. Further studies are warranted to improve functional outcomes in SA with CAD.
