Type 2 diabetes in Belgians of Turkish and Moroccan origin

Intercultural effectiveness in GPs' communication and clinical assessment: An experimental study

OBJECTIVE

This study aimed to investigate potential disparities in general practitioners' overall communication and clinical assessments based on patient ethnicity, while examining the influence of intercultural effectiveness.

METHODS

Employing a 2 × 2 experimental study design, online video recorded consultations with simulated patients were conducted and analyzed using OSCEs. Each GP (N = 100) completed a consultation with both an ethnic majority and an ethnic minority patient. Additionally, a follow-up survey was administered to gather supplementary data. Paired sample t-tests explored ethnic disparities, correlation and regression analyses determined associations with intercultural attitudes, traits and capabilities.

RESULTS

No statistically significant differences in GPs' communication or clinical assessment were found based on patients' ethnic background. Positive associations were observed between all aspects of intercultural effectiveness and GPs' consultation behavior. Intercultural traits emerged as a strong and robust predictor of clinical assessment of ethnic minority patients.

CONCLUSION

Intercultural traits, such as ethnocultural empathy, may play a critical role in GPs' clinical assessment skills during intercultural consultations.

PRACTICE IMPLICATIONS

Findings provide valuable insights into the determinants of intercultural effectiveness in healthcare, fostering promising targets for interventions and training programs aiming to ensure higher-quality and more equitable care delivery.

Exercise as a non-pharmacological intervention to protect pancreatic beta cells in individuals with type 1 and type 2 diabetes

AIMS/HYPOTHESIS

Diabetes is characterised by progressive loss of functional pancreatic beta cells. None of the therapeutic agents used to treat diabetes arrest this process; preventing beta cell loss remains a major unmet need. We have previously shown that serum from eight young healthy male participants who exercised for 8 weeks protected human islets and insulin-producing EndoC-βH1 cells from apoptosis induced by proinflammatory cytokines or the endoplasmic reticulum (ER) stressor thapsigargin. Whether this protective effect is influenced by sex, age, training modality, ancestry or diabetes is unknown.

METHODS

We enrolled 82 individuals, male or female, non-diabetic or diabetic, from different origins, in different supervised training protocols for 8-12 weeks (including training at home during the COVID-19 pandemic). EndoC-βH1 cells were treated with 'exercised' serum or with the exerkine clusterin to ascertain cytoprotection from ER stress.

RESULTS

The exercise interventions were effective and improved [Formula: see text] values in both younger and older, non-obese and obese, non-diabetic and diabetic participants. Serum obtained after training conferred significant beta cell protection (28% to 35% protection after 4 and 8 weeks of training, respectively) from severe ER stress-induced apoptosis. Cytoprotection was not affected by the type of exercise training or participant age, sex, BMI or ancestry, and persisted for up to 2 months after the end of the training programme. Serum from exercised participants with type 1 or type 2 diabetes was similarly protective. Clusterin reproduced the beneficial effects of exercised sera.

CONCLUSIONS/INTERPRETATION

These data uncover the unexpected potential to preserve beta cell health by exercise training, opening a new avenue to prevent or slow diabetes progression through humoral muscle-beta cell crosstalk.

Diabetes and Cardiovascular Diseases Risk Assessment in Community Pharmacies: An Implementation Study

The implementation of a new service is often challenging when translating research findings into routine clinical practices. This paper presents the results of the implementation study of a pilot project for a diabetes and cardiovascular diseases risk-assessment service in Belgian community pharmacies. To evaluate the implementation of the service, a mixed method was used that follows the RE-AIM framework. During the testing stage, 37 pharmacies participated, including five that dropped out due to a lack of time or COVID-19-related temporary obligations. Overall, 502 patients participated, of which 376 (74.9%) were eligible for according-to-protocol analysis. Of these, 80 patients (21.3%) were identified as being at high risk for the targeted diseases, and 100 (26.6%) were referred to general practice for further investigation. We presented the limited effectiveness and the key elements influencing optimal implementation. Additional strategies, such as interprofessional workshops, a data-sharing platform, and communication campaigns, should be considered to spread awareness of the new role of pharmacists. Such strategies could also promote collaboration with general practitioners to ensure the follow-up of patients at high risk. Overall, this service was considered easy to perform and feasible in practice but would require financial and external support to ensure its effectiveness, sustainability, and larger-scale implementation.

Microvascular and macrovascular complications in type 2 diabetes in a multi-ethnic population based in Amsterdam. The HELIUS study

OBJECTIVE

To assess ethnic differences in diabetes-related microvascular and macrovascular complication rates in a multi-ethnic population in the Netherlands.

STUDY, DESIGN AND SETTING

Data from the HELIUS study comprising of 165 Dutch, 591 South-Asian Surinamese, 494 African Surinamese, 272 Ghanaian, 368 Turkish, and 444 Moroccan participants with diabetes were analyzed. Logistic regression was used to assess ethnic differences in microvascular (nephropathy) and macrovascular (coronary heart disease (CHD), peripheral artery disease (PAD) and stroke) complications, with adjustments for age, sex, education, and the conventional risk factors.

RESULTS

In an age-sex adjusted model, ethnic minorities had higher odds of nephropathy than Dutch except for Ghanaians and African Surinamese. The difference remained statistically significant in South-Asian Surinamese (odds ratio: 2.29; 95% CI, 1.09-4.80), but not in the Turkish (1.01; 0.43-2.38) and Moroccan (1.56; 0.68-3.53) participants. The odds of CHD was higher in all ethnic minorities than in Dutch, with the odds ratios ranging from 2.73 (1.09-6.84) in Ghanaians to 6.65 (2.77-15.90) in Turkish in the fully-adjusted model. There were no ethnic differences in the odds of PAD and stroke.

CONCLUSIONS

The findings suggest ethnic inequalities in macrovascular and microvascular complications in diabetes, with nephropathy and CHD being the most common complications affecting ethnic minorities.

High rates of atherogenic dyslipidemia, β-cell function loss, and microangiopathy among Turkish migrants with T2DM

AIMS

Non-Caucasian migrants require dedicated approaches in diabetes management due to specific genetic; socio-cultural; demographic and anthropological determinants. Documenting such phenotypes allows for better understanding unmet needs and management priorities.

METHODS

This age- and sex-adjusted case-control (1:6 ratio) study compared 56 T2DM Turkish migrants (70% males) resident in Belgium [Tu] with 336 T2DM Caucasians [Ca], all benefiting from state-funded healthcare.

RESULTS

The 2 groups did not differ regarding BMI; waist circumference; fat mass; visceral fat; muscle mass; insulin sensitivity; insulinemia; metabolic syndrome; hypertension; lipid-modifying drugs; and macroangiopathy. They also had similar renal function and (micro)albuminuria. Education (low/high) and ethanol consumption were lower among [Tu]: 83/17% and 2.0 U/wk vs 43/57% and 13.6 U/wk in [Ca] (p < 0.0001). β-cell function loss (BCF) was higher in [Tu]: 1.58(0.45) vs 1.35(0.54)%/yr (p 0.0027), as was HbA1c: 8.39(1.91) vs 7.48(1.35)% in [Ca] (p < 0.0001). Diabetes duration and insulin use were increased in [Tu]: 19(9)yr and 70% vs 16(8)yr and 48% in [Ca] (p 0.0111 and 0.0024). Atherogenic dyslipidemia (AD) was more prevalent in [Tu]: 64% vs 49% (p 0.0309), who had higher non-HDL-C; apolipoprotein B₁₀₀; LDL-C; and triglycerides; and lower HDL-C and apolipoprotein A-I levels (all p < 0.05). Overall microangiopathy; retinopathy; and neuropathy were more prevalent in [Tu]: 55-35-37% vs 40-18-20% in [Ca] (all p < 0.05).

CONCLUSIONS

These results should raise concerns about poor glycaemic control; rapid BCF loss; severe AD; and microangiopathy among Turkish migrants with T2DM. Targeting AD could improve the cardiometabolic profile of this minority given the relationship between AD and residual vascular risk.

Leadership and cultural competence of healthcare professionals: a social network analysis

BACKGROUND

International migration is a global phenomenon challenging healthcare professionals to provide culturally competent care.

OBJECTIVES

The purpose of this study was to investigate the influence of leaders on the cultural competence of healthcare professionals.

METHODS

A cross-sectional survey was conducted from 2010 to 2012 to obtain data for a social network analysis in 19 inpatient services and five primary care services in Belgium. The Competences in Ethnicity and Health questionnaire was used. A total of 507 healthcare professionals, including 302 nurses, identified their social relationships with other healthcare professionals working in their service. Highest in-degree centrality was used to identify the leaders within each health service. Multiple regressions with the Huber sandwich estimator were used to link cultural competence of leaders with the cultural competence of the rest of the healthcare staff.

RESULTS

Cultural competence of the healthcare staff was associated with the cultural competence of the leaders. This association remained significant for two specific domains of cultural competence-mediation and paradigm-after controlling for contextual and sociodemographic variables. Interaction analysis suggested that the leadership effect varied with the degree of cultural competence of the leaders.

DISCUSSION

Cultural competence among healthcare professionals is acquired partly through leadership. Social relationships and leadership effects within health services should be considered when developing and implementing culturally competent strategies. This requires a cautious approach as the most central individuals are not always the same persons as the formal leaders.

Is the Chronic Care Model Integrated Into Research Examining Culturally Competent Interventions for Ethnically Diverse Adults With Type 2 Diabetes Mellitus? A Review

The chronic care model (CCM) concerns both the medical and the cultural and linguistic needs of patients through the inclusion of cultural competence in the delivery system design. This literature review attempted to@@ identify the domains of the CCM culturally competent (CC) interventions that the adults from ethnic minorities suffering from type 2 diabetes mellitus report. We identified the CCM and the CC components in the relevant studies published between 2005 and 2014. Thirty-two studies were included. Thirty-one articles focused on self-management and 20 on community resources. Twenty-three interventions integrated cultural norms from the patients’ backgrounds. CC interventions reported the CCM at the individual level but need to address the organizational level more effectively. The scope of CC interventions should be expanded to transform health care organizations and systems.

Understanding medication adherence among patients of Turkish descent with type 2 diabetes: a qualitative study

OBJECTIVES

To explore perspectives of Turkish migrants with type 2 diabetes mellitus (T2DM) on adherence to oral hypoglycaemic agents (OHA).

DESIGN

In-depth interviews with 21 T2DM patients of Turkish descent recruited from primary care and community sources in Ghent, Belgium, using a theoretical sampling procedure. Analysis was guided by a grounded theory approach, using Nvivo 8.

RESULTS

Respondents reported a multitude of barriers and facilitators of adherence to OHA. Some of these barriers are distinctive for T2DM patients of Turkish descent. Respondents' causal beliefs about stress and the Belgian climate often led to non-adherence during less stressful periods, like summer holidays in Turkey. Some respondents adjusted their medication use to food intake or during Ramadan fasting. Concerns about OHA were the main reason for the widespread use of herbal medicine in this sample. The religious framework used to interpret diabetes led, in combination with feelings of depression, to non-adherence in some respondents while it facilitated medication adherence in others. A potential gender effect with respect to the self-management of OHA was observed. Non-distinctive factors include: beliefs about OHA, polypharmacy, beliefs about the course of diabetes, forgetfulness, the perception of the doctor's medical expertise, feelings of depression and social support.

CONCLUSION

Health care providers should explore in detail and regularly patients' perspectives on illness beliefs, medication beliefs and their trust in doctors' medical expertise as this will provide useful starting points for promoting medication adherence. Whenever possible health care workers should engage with their patients in therapeutic alliances.

Culturally competent interventions in Type 2 diabetes mellitus management: an equity-oriented literature review

OBJECTIVES

Although, culturally competent (CC) interventions aim to reduce health inequalities for ethnic minorities, they have been criticized on the grounds that they increase prejudice and stereotyping. It remains unclear whether CC interventions really can reduce health inequalities among ethnic minorities. The purpose of this review is to assess whether CC interventions in the management of Type 2 diabetes mellitus (T2DM) match the recommendations to reduce health inequalities.

DESIGN

We identified CC interventions relating to T2DM among ethnic minority patients in the literature published between 2005 and 2011. Data were analyzed according to an equity-oriented framework. Each study was given a score based on its congruence with the reduction of health inequalities amongst ethnic minorities.

RESULTS

We reviewed 137 papers and found 61 studies that met the inclusion criteria. Most interventions focused on the individual level and the modification of patients' health behavior. Very few addressed the sociopolitical level. A minority of the studies acknowledged the role of socioeconomic deprivation in ethnic health inequalities. Half of the studies contained no information about the socioeconomic status of the patients. The patients receiving the interventions were socioeconomically deprived. Only 10 studies compared ethnic minority groups to majority groups. Thirty-three studies had a very low average congruence score. The highest score of congruence was achieved by one study.

CONCLUSION

Overall, CC interventions addressing T2DM are not congruent with the reduction of ethnic health inequalities. The future of CC interventions may involve going one step further and going back to basic tenets of cultural competence: the integration of difference, whatever its source, into the delivery of fair health care for patients.

Towards fair health policies for migrants and ethnic minorities: the case-study of ETHEALTH in Belgium

BACKGROUND

In Europe, progress in the development of health policies that address the needs of migrants and ethnic minorities has been slow. This is partly due to the absence of a strategic commitment by the health authorities. The Ministry of Public Health commissioned the ETHEALTH (EThnicity &HEALTH) group to formulate relevant recommendations to the public authorities with a view to reducing health inequalities among ethnic minorities. This paper describes the political process and the outcomes of the ETHEALTH expert group.

RESULTS

After ten meetings, the ETHEALTH group came up with 46 recommendations, which were presented at a national press conference in December 2011. Target groups concerned by these recommendations covered both irregular migrants and migrants entitled to the national insurance coverage. Recommendations were supported by the need of combining universal approaches to health care with more specific approaches. The scope of the recommendations concerned health care as well as prevention, health promotion and access to health care. When analysing the content of the recommendations, some ETHEALTH recommendations were not fully measurable, and time-related; they were, however, quite specific and realistic within the Belgian context. The weak political commitment of an executive agency was identified as a major obstacle to the implementation of the recommendations.

CONCLUSIONS

The ETHEALTH group was an example of scientific advice on a global health issue. It also demonstrated the feasibility of coming up with a comprehensive strategy to decrease ethnic health inequalities, even in a political context where migration issues are sensitive. Two final lessons may be highlighted at the end of the first phase of the ETHEALTH project: firstly, the combination of scientific knowledge and practical expertise makes recommendations SMART; and, secondly, the low level of commitment on the part of policymakers might jeopardise the effective implementation of the recommendations.

Migrant mortality from diabetes mellitus across Europe: the importance of socio-economic change

The first objective of this study was to determine and quantify variations in diabetes mortality by migrant status in different European countries. The second objective was to investigate the hypothesis that diabetes mortality is higher in migrant groups for whom the country of residence (COR) is more affluent than the country of birth (COB). We obtained mortality data from 7 European countries. To assess migrant diabetes mortality, we used direct standardization and Poisson regression. First, migrant mortality was estimated for each country separately. Then, we merged the data from all mortality registers. Subsequently, to examine the second hypothesis, we introduced gross domestic product (GDP) per capita of COB in the models, as an indicator of socio-economic circumstances. The overall pattern shows higher diabetes mortality in migrant populations compared to local-born populations. Mortality rate ratios (MRRs) were highest in migrants originating from either the Caribbean or South Asia. MRRs for the migrant population as a whole were 1.9 (95% CI 1.8-2.0) and 2.2 (95% CI 2.1-2.3) for men and women respectively. We furthermore found a consistently inverse association between GDP of COB and diabetes mortality. Most migrant groups have higher diabetes mortality rates than the local-born populations. Mortality rates are particularly high in migrants from North Africa, the Caribbean, South Asia or low-GDP countries. The inverse association between GDP of COB and diabetes mortality suggests that socio-economic change may be one of the key aetiological factors.

Ethnic differences in diabetes-related mortality in the Brussels-Capital Region (2001-05): the role of socioeconomic position

OBJECTIVES

To examine if and to what extent ethnic differences in diabetes-related mortality are associated with differences in education and housing status.

METHODS

The data consist of a cohort study linking the 2001 census to emigration and mortality data for the period 2001-05. The study population comprises all Belgian and North African inhabitants of the Brussels-Capital Region (BCR) aged 25-74. Age-standardized mortality rates (ASMRs) (direct standardization) and mortality rate ratios (MRRS) (Poisson regression) are computed.

RESULTS

North Africans have a higher diabetes-related mortality compared to Belgians. The ASMRs for North African and Belgian women are 54.8 (95% confidence interval (CI) 31.5-78.2) and 23.8 (95% CI 20.3-27.3), respectively. These differences in diabetes-related mortality largely disappear when differences in education are taken into account. The MRRs for North African versus Belgian origin drop from 1.62 (95% CI 1.11-2.37) to 1.19 (95% CI 0.73-1.93) in men and from 3.35 (95% CI 2.08-5.41) to 1.88 (95% CI 0.95-3.69) in women.

CONCLUSIONS

Differences in education play an important part in the excess diabetes-related mortality among North Africans in the BCR.
