Diabetes among migrants in Denmark: Incidence, mortality, and prevalence based on a longitudinal register study of the entire Danish population

Survival outcomes and healthcare utilization between immigrant patients and Danish-born patients with hematological cancers: a Danish population-based study

Overall survival (OS) for patients with a hematological cancer may differ between immigrant and Danish-born patients due to disparities in socioeconomic status, health literacy, and language proficiency. This cohort study aimed to investigate survival and hospitalization according to immigrant status while controlling for confounders. Patients with newly diagnosed hematological cancer in 2000-2020 were identified in the Danish nationwide hematological registers and stratified into Danish-born, Western, and non-Western patients. Patients were followed from diagnosis until death, 31st December 2021, or emigration, whichever came first. Crude OS, standardized OS, and 5-years OS differences were computed using flexible parametric models and hazard ratios using Cox regression. Number of hospitalization days in the year before and after diagnosis, respectively, were calculated using Poisson regression. A total of 2,241 immigrants and 41,519 Danish-born patients with a hematological cancer were included. Standardized 5-years OS was similar between groups with 58% (95% confidence interval 57-58%) for Danish-born patients, 57% (55-60%) for Western, and 56% (53-58%) for non-Western immigrant patients. Subgroup analyses identified OS differences in selected subgroups. Non-Western immigrant patients had 1.3 (0.5-2.1) more hospitalization days in the year before diagnosis and an adjusted incidence rate ratio of hospitalization days of 1.14 (1.13-1.15) in the year after diagnosis compared with Danish-born patients. In conclusion, there were no overall differences in survival when comparing immigrant patients to Danish-born patients after controlling for relevant confounders. Healthcare utilization was slightly higher among non-Western immigrant patients before and after diagnosis, but differences were small on an individual patient level.

Acquisition, application, and distribution of health literacy from culturally sensitive type 2 diabetes education among Arabic-Speaking migrants in Denmark: A longitudinal qualitative analysis

BACKGROUND

Effective self-management of type 2 diabetes requires adequate health literacy (HL) and a supportive network. Diabetes self-management education and support programmes play a crucial role in improving these factors. However, limited research exists on how such programmes can support health literacy among migrants and facilitate the dissemination of knowledge within their social networks.

AIM

This study aimed to investigate the perspectives of Arabic-speaking informants with a migrant background in relation to how their type 2 diabetes-related health literacy was acquired, applied and distributed within social networks through participation in a culturally sensitive diabetes self-management education and support (DSMES) programme.

METHODS

Semi-structured interviews were conducted with 12 informants during the programme and three to 7 months later, from September 2019 to May 2020. Abductive analysis was applied using HL and distributed health literacy (DHL) theory as frameworks.

RESULTS

The analysis generated three themes: (1) sources of health information and the development of health literacy; (2) changes towards active self-management; and (3) distributed health literacy. Prior to programme participation, informants faced challenges in navigating conflicting information from family, friends and social media. After participating in the programme, they reported improvements in HL, particularly in knowledge acquisition. Many became more actively engaged in decision-making and exhibited improved health behaviours, such as dietary choices. Nonetheless, some informants continued to struggle with choosing appropriate prevention and treatment strategies. Notably, certain informants acted as HL mediators, sharing their newly acquired knowledge within their social networks in Denmark and abroad.

CONCLUSION

Culturally sensitive diabetes self-management education programmes have the potential to enhance HL among migrants, leading to the distribution of relevant diabetes knowledge within their social networks. Future studies should explore how members of migrants' social networks perceive their supportive role in type 2 diabetes management. Programmes can benefit from emphasising critical HL and exploring how participant-informants effectively communicate diabetes-related knowledge within their networks to address misinformation and conflicting information.

Guideline-level monitoring, biomarker levels and pharmacological treatment in migrants and native Danes with type 2 diabetes: Population-wide analyses

The prevalence of type 2 diabetes (T2D) is higher in migrants compared to native populations in many countries, but the evidence on disparities in T2D care in migrants is inconsistent. Therefore, this study aimed to examine this in Denmark. In a cross-sectional, register-based study on 254,097 individuals with T2D, 11 indicators of guideline-level care were analysed: a) monitoring: hemoglobin-A1c (HbA1c), low-density lipoprotein cholesterol (LDL-C), screening for diabetic nephropathy, retinopathy, and foot disease, b) biomarker control: HbA1c and LDL-C levels, and c) pharmacological treatment: glucose-lowering drugs (GLD), lipid-lowering drugs, angiotensin-converting enzyme-inhibitors/angiotensin receptor blockers, and antiplatelet therapy. Migrants were grouped by countries of origin: Middle East, Europe, Turkey, Former Yugoslavia, Pakistan, Sri Lanka, Somalia, Vietnam. In all migrant groups except the Europe-group, T2D was more prevalent than in native Danes (crude relative risk (RR) from 0.62 [0.61-0.64] (Europe) to 3.98 [3.82-4.14] (Sri Lanka)). In eight indicators, non-fulfillment was common (>25% among native Danes). Apart from monitoring in the Sri Lanka-group, migrants were at similar or higher risk of non-fulfillment than native Danes across all indicators of monitoring and biomarker control (RR from 0.64 [0.51-0.80] (HbA1c monitoring, Sri Lanka) to 1.78 [1.67-1.90] (LDL-C control, Somalia)), while no overall pattern was observed for pharmacological treatment (RR from 0.61 [0.46-0.80] (GLD, Sri Lanka) to 1.67 [1.34-2.09] (GLD, Somalia)). Care was poorest in migrants from Somalia, who had increased risk in all eleven indicators, and the highest risk in nine. Adjusted risks were elevated in some migrant groups, particularly in indicators of biomarker control (fully-adjusted RR from 0.84 [0.75-0.94] (LDL-C levels, Vietnam) to 1.44 [1.35-1.54] (LDL-C levels, Somalia)). In most migrant groups, T2D was more prevalent, and monitoring and biomarker control was inferior compared to native Danes. Migrants from Somalia received the poorest care overall, and had exceedingly high lipid levels.

Developing a Culturally Appropriate Tool to Support Self-Care in Migrants with Type 2 Diabetes - A Co-Design Study

Introduction

Migrants, especially from the Middle East, experience poorer health outcomes and face greater difficulties in accessing healthcare compared to native populations and there is a need for culturally appropriate education for this vulnerable group. The purpose of this study is to describe the process of developing a culturally appropriate tool to support self-care in migrants with type 2 diabetes.

Methods

In this Co-design study, a tool for supporting self-care in migrants with type 2 diabetes was developed. Migrant patients with type 2 diabetes, healthcare providers and researchers participated in the process, which was based on six elements; engage, plan, explore, develop, decide and change. From February 2021 to December 2022, idea groups were conducted, and a tool was developed through brainstorming, prioritizing and prototyping.

Results

In total, 14 migrant patients, ten health care providers and four researchers participated in the Co-design process. The patients wished to receive information about type 2 diabetes self-care behaviour in their own languages. The healthcare providers asked for clear instructions on where to guide their patients regarding reliable information about diabetes in the patient's own language. All participants agreed that information can be presented in different formats, either: text (paper or online), audio-visual via recorded videos and/or lectures and pictures.

Discussion

The Co-design process led to several important insights and experiences related to the importance of diverse cultural backgrounds. When conducting a Co-design study with end-users as stakeholders, it is significant that the stakeholders have a diverse background in experiences, both as patients as well as those who deliver or implement the health service. In this study it was of great importance to include patients with diverse backgrounds regarding; gender, age, health literacy, occupation, years living in Sweden and duration of diabetes.

Disparities in cardiovascular disease and treatment in the Nordic countries

The Nordic countries, including Denmark, Finland, Iceland, Norway, and Sweden have seen a steep decline in cardiovascular mortality in recent decades. They are among the most egalitarian countries by several measures, and all have universal, publicly funded welfare systems providing healthcare for all citizens. However, despite these seemingly ideal conditions, disparities in access to cardiovascular care and outcomes persist. To address this challenge, The Lancet Region Health-Europe convened experts from a broad range of countries to summarize the current state of knowledge on cardiovascular disease disparities across Europe. This Series Paper presents the main challenges in Nordic countries based on evidence from high-quality nationwide registries. Focusing on major cardiovascular health determinants, areas in need of improvement were identified. There is a need for addressing structural causes underlying these disparities, such as poverty and discrimination, but also to improve access to healthcare in deprived neighborhoods and to address underlying social determinants of health that may mitigate disparities in cardiovascular outcomes. Overall, while the Nordic countries have made great strides in promoting egalitarianism and providing universal healthcare, there is still much work to be done to ensure equitable access to care and improved cardiovascular outcomes for all members of society.

Improving Health and Diabetes Self-Management in Immigrants with Type 2 Diabetes Through a Co-Created Diabetes Self-Management Education and Support Intervention

To examine the impact of a co-created culturally sensitive diabetes self-management education and support (DSMES) intervention on the physical and mental health of immigrants with type 2 diabetes (T2D). Pre- and post-test among people with T2D whose primary language was Urdu, Arabic or Turkish (n = 97). Participants were offered a six-week intervention based on a person-centred approach using research-based dialogue tools to facilitate learning and reflection, which was developed in co-creation with immigrants and healthcare professionals. Data were collected at baseline, post-intervention and after 6 months and analysed using paired t-tests, Wilcoxon signed-rank tests, chi-square tests and regression models when appropriate. Several clinical outcomes were improved post-intervention, including HbA1c (P < 0.001), body fat percentage (P = 0.002), self-rated general health (P = 0.05), well-being (P = 0.004) and several self-management behaviours, e.g., physical activity (P < 0.001). Most outcomes remained improved after 6 months, but the effect on HbA1c was no longer statistically significant. Some outcomes were improved only at 6 months, including waist circumference (P < 0.001) and diabetes-related emotional distress (P < 0.001). Fatigue did not change. Attendance at more programme sessions was associated with better outcomes. The DSMES intervention developed in a co-creation process was highly effective in improving the health of immigrants with T2D.

Gestational Diabetes and International Migration

In many countries, immigrant women constitute a substantial proportion of women giving birth. With gestational diabetes being one of the most common complications in pregnancy, understanding gestational diabetes in the context of international migration becomes increasingly relevant. Here, we examine the current evidence related to international migration and gestational diabetes, including short- and long-term adverse outcomes and the experiences of immigrant women with gestational diabetes care and long-term follow-up. Existing evidence focuses on immigrants in high-income countries, and has mainly examined differences in the risk of developing gestational diabetes, or on the experiences of immigrant women diagnosed with gestational diabetes. Studies suggest that the risk of gestational diabetes may be influenced by migration and that immigrant women likely experience particular barriers to care and follow-up. Current research on perinatal outcomes is inconclusive and studies on long-term outcomes are practically absent. Future research should include data on country of origin and examine the role of premigration and postmigration factors in developing gestational diabetes and its associated short- and long-term outcomes. Understanding these factors will provide useful insights into improving the health and health care needs of migrating populations and enable inclusion of culturally appropriate health care practices, thereby improving the health of our current and future generations.

Migration health research in the Nordic countries: Priorities and implications for public health

The past 50 years have witnessed an increase in immigration to the Nordic countries from and beyond neighbouring countries in Europe. Diversity implies variations and differences in health status and health outcomes both within and across populations. Migrant health research has not been prioritized and health policies and practice, especially long-term national plans, often exclude migrants. In this article, we briefly trace the history, the groups, reasons for migration and the road to migrant health research in Norway, Sweden, Finland and Denmark. We discuss the case for data and research including needs, basis for data collection and the methodological challenges. We provide a brief snapshot of migrant health research, identify current gaps and discuss the implications for research. We recommend a regional Nordic strategy to promote intercountry exchange, sharing and learning. Finally, we reflect on the larger picture, implications for policy and practice that could enable societal conditions to reduce avoidable health inequalities.

Newly arrived refugees’ perception of health and physical activity in Denmark

•

The newly arrived refugees spoke of a broad and holistic perspective on health, where health is understood as a part of life and therefore more than just the absence of illness.

•

Physical activity was by the male newly arrived refugees explained as important instrument to ensure that they could provide for their family (e.g. economy and demands).

•

Female newly arrived refugees were more explicit on the compromises they had to make with being physical active, in order to be the “expected” caretaker of their family.

•

Refugees experienced several barriers for doing physical activity and living healthy lives. Time, pain, low income, job insecurity, mental strain, discourse of health and physical activity, external expectations and demands (municipality and government), precariat living conditions and general worrying, were amongst the most explicit barriers.

Refugees health status after receiving asylum in their new country is often poor, both physical and mentally. Despite that, European countries rarely offer programmes specifically targeted health and health behaviour for newly arrived refugees. This study investigated newly arrived refugees’ perspective on health and in particularly physical activity (PA) upon granted asylum in Denmark. A transnational migration perspective provides the theoretical framework in this study. Semi-structured interviews with twenty newly arrived refugees provide data for the interpretative phenomenological analysis (IPA). Health manifests itself in varied ways to the newly arrived refugees and a broad and holistic perspective on health, was evident. Overall PA had important benefits, such as pain relief, better physical fitness, lose weight, a stronger body, to stay active, cater to mental health and in general something of interest to the newly arrived refugees. However, the informants experienced several barriers for doing PA and living healthy lives. Time, pain, low income, job insecurity, mental strain, discourse of health and PA (health promotion), external expectations and demands (municipality and government in Denmark), precariat living conditions and general worrying were amongst the most explicit barriers. In addition, the question of how the newly arrived refugees are positioned in their families seems vital, as patriarchal family structures seem to prevent some from doing PA. Based on the results, we underline the importance of involving refugees in developing health promotion activities while considering of their unique experiences and transnational background.

Socioeconomic and demographic risk factors in COVID-19 hospitalization among immigrants and ethnic minorities

BACKGROUND

Immigrants and ethnic minorities have been shown to be at increased risk of hospitalization from COVID-19. Our aim was to analyse the contribution of socioeconomic and demographic risk factors on hospital admissions for COVID-19 among immigrants and ethnic minorities compared to the majority population.

METHODS

We used nationwide register data on all hospitalized COVID-19 cases between February and June 2020 (N = 2232) and random controls from the general population (N = 498 117). We performed logistic regression analyses and adjusted for age, sex, comorbidity, and socioeconomic and demographic factors. The main outcome measure was hospitalization with COVID-19 and was estimated using odds ratios (OR) and 95% confidence intervals (95% CI).

RESULTS

Among 2232 COVID-19 cases, the OR of hospitalization with COVID-19 among immigrants and descendants of non-Western origin was 2.5 times higher (95% CI: 2.23-2.89) compared with individuals of Danish origin with most pronounced results among individuals from Iraq, Morocco, Pakistan and Somalia. The OR was largely attributed to comorbidity and socioeconomic factors, especially household size, occupation, and population density.

CONCLUSION

There is a significantly higher OR of hospitalization with COVID-19 among non-Western immigrants and ethnic minorities compared with ethnic Danes. This knowledge is crucial for health policymakers and practitioners in both the current and future pandemics to identify more vulnerable groups and target prevention initiatives.

Risk of Developing Type 2 Diabetes in Individuals With a Psychiatric Disorder: A Nationwide Register-Based Cohort Study

OBJECTIVE

Previous studies have investigated the incidence of type 2 diabetes in individuals with psychiatric disorders, but most studies have focused on a specific psychiatric disorder or a selected sample. More population-based studies are needed to determine these associations in representative samples. We therefore aimed to determine these associations in a nationwide, register-based dynamic cohort study.

RESEARCH DESIGN AND METHODS

We analyzed data from 5,005,612 adults living in Denmark between 1995 and 2018, without prior diabetes. We investigated 10 different categories of psychiatric disorders and a composite group with any psychiatric disorder. Individuals with a psychiatric disorder were compared with individuals without using multivariable-adjusted Poisson regression to estimate incidence rate ratios (IRR) of type 2 diabetes. We modeled age-specific incidence rates (IR) for individuals with and without the specific psychiatric disorder. All models were stratified by sex.

RESULTS

In total, 334,739 individuals developed type 2 diabetes during follow-up. For all investigated categories of psychiatric disorders, we found increased IR of type 2 diabetes for individuals with versus those without a psychiatric disorder (IRR: men, 1.47 [95% CI 1.45-1.50]; women, 1.65 [95% CI 1.62-1.68]). When we examined age-specific IR, the largest differences were found in the younger population (<50 years).

CONCLUSIONS

We found that the IR of type 2 diabetes was higher in individuals with a psychiatric disorder compared with individuals without a psychiatric disorder and particularly high in the younger people with a psychiatric disorder. New studies into the prevention and early detection of type 2 diabetes in these groups are warranted.

Undocumented migrants in French intensive care units in 2011-2018: retrospective nationwide study

PURPOSE

Whether undocumented migrants admitted to intensive care units (ICUs) have specific features is unknown. We aimed to determine the features and outcomes of undocumented migrants admitted to French ICUs.

METHODS

We retrospectively included all undocumented adult migrants admitted in 2011-2018 and compared them to the general ICU population. We also compared these two groups matched on age, sex, severity, comorbidities, reason for ICU admission and public/private hospital.

RESULTS

We identified 14,554 ICU stays, with an increase from 2 to 4‰ of all ICU admissions over time. Shock (16.7%), post-operative care (13.8%), and trauma (10.5%) were the main reasons for ICU admission. Compared to general ICU patients, migrants were younger and had greater disease severity. After adjustment on age and sex, the following were more common in migrants: shock (OR 1.2 [1.14-1.25]; P < 0.0001), infections (1.48 [1.38-1.54]; P < 0.001), acute respiratory failure (1.09 [1.03-1.15]; P = 0.006), acute kidney injury (1.12 [1.05-1.19]; P < 0.001), obstetric events (1.53 [1.66-1.81]; P < 0.0001), and neurological deficits (1.19 [1.12-1.27]; P < 0.0001). In the matched study, migrants more often required vasopressors, mechanical ventilation, and renal replacement therapy; had longer ICU stays (median 4 [2-8] vs. 4 [2-7] days; P < 0.0001) and hospital stays (10 [5-20] vs. 8 [4-15]; P < 0.0001) and had higher hospital costs (14.2 ± 23.6 vs. 13.4 ± 11.5 K€; P < 0.0001). Hospital mortality was similar (6.7% vs. 6.6%; P = 0.69).

CONCLUSION

Admissions of undocumented migrants to French ICUs doubled from 2011 to 2018. The patients were younger and, although sicker, achieved similar outcomes to those in general ICU patients.

Incidence of stroke, transient ischaemic attack and determinants of poststroke mortality among immigrants in Denmark, 2004‒2018: a population-based cohort study

OBJECTIVE

Using recent registry data, we aimed to quantify the incidence of stroke and transient ischaemic attack (TIA) and to examine factors influencing the risk of poststroke mortality among immigrants compared with Danish-born individuals.

DESIGN

Population-based cohort study between 2004 and 2018. We estimated age-standardised incidence rate ratios (IRR) of stroke, stroke types and TIA for each ethnic group using Danish-born individuals as the reference by direct method of standardisation. We calculated the risk of poststroke mortality using Cox proportional hazard regression.

SETTING

The study was conducted using Danish nationwide registers.

PARTICIPANTS

All cases of first-ever stroke and TIA by country of origin (n=132 936) were included.

RESULTS

Overall, Western immigrants (IRR=2.25; 95% CI 2.20 to 2.31) and non-Western immigrants (IRR=1.37; 95% CI 1.30 to 1.44) had a higher risk of stroke than Danish-born individuals. The risk of TIA was higher in Western immigrants (IRR=2.08; 95% CI 1.93 to 2.23) followed by non-Western immigrants (IRR=1.45; 95% CI 1.27 to 1.63) than in Danish-born individuals. All-cause 1-year mortality hazard was higher but not significantly different in non-Western men (adjusted HR=1.38; 95% CI 0.92 to 2.08) compared with Danish-born men and additional adjustment for comorbidities reduced the HR to 0.85 (0.51 to 1.40) among ischaemic stroke cases. Among intracerebral haemorrhage cases, the adjusted mortality hazard was decreased in Western men (from HR of 1.76; 95% CI 1.09 to 2.85 to HR of 1.30; 95% CI 0.80 to 2.11) compared with Danish-born men after adjustment for stroke severity. Immigrants with ≤15 years of residence had a lower poststroke mortality hazard than Danish-born individuals after additional adjustment for sociodemographic factors (HR=0.36; 95% CI 0.14 to 0.91).

CONCLUSIONS

The age-standardised risk of stroke and TIA was significantly higher among the majority of immigrants than Danish-born individuals. Interventions that reduce the burden of comorbidities, improve acute stroke care and target sociodemographic factors may address the higher risk of poststroke mortality among immigrants.

The Danish "11 for Health" program raises health knowledge, well-being, and fitness in ethnic minority 10- to 12-year-olds

OBJECTIVES

This study investigated the effects of the health promotion intervention "11 for Health in Denmark" program on 10- to 12-year-old ethnic minority schoolchildren's enjoyment, health knowledge, well-being, and fitness.

METHODS

1122 Danish 5th grade schoolchildren with ethnic minority background from 154 schools were randomized (5:1) to an intervention group (IG, n = 944) or a control group (CG, n = 178). The IG and CG were also divided into subgroups of children active in a sports club (IGPA: n = 644; CGPA: n = 122) and not active in a sports club (IGPI: n = 300, CGPI: n = 56). IG participated in the "11 for Health in Denmark" 11-week program, consisting of 2 × 45 min per week of football drills, small-sided games, and health education, whereas CG continued their regular activities. Pre-post physical testing and questionnaires were applied (short version of the multidimensional well-being questionnaire KIDSCREEN-27, and a 34-item health knowledge questionnaire).

RESULTS

The "11 for Health in Denmark" program was rated moderate-to-high on a 1-5 scale for enjoyment by girls (3.57) and boys (3.65). The intervention had positive between-group effect on health knowledge in relation to hygiene (IG vs GC: 10.6% points (CI95%: 6.9:14.3), p < 0.05), nutrition (9.6% point (CI95%: 7.4:11.8), p < 0.01) and physical activity 4.4% points (CI95%: 2.2:6.6) as well as overall health knowledge (5.7% points, (CI95%: 4.3;7.1), p < 0.05), with similar effects for girls and boys. The IGPI subgroup showed a positive effect on well-being (p = 0.04, school and learning) and also fitness effects on performance and VO₂  max (p = 0.02: p = 0.01). The IGPA subgroup showed a positive effect on fitness scores (p = 0.02, BMI).

CONCLUSION

The intervention program was enjoyable and had a positive impact on health knowledge of ethnic minority background schoolchildren. In addition, the intervention program had the strongest positive effects on well-being and fitness scores for the non-sports club-active children.

Knowledge and perceptions around self-management of type 2 diabetes among a Sudanese community in Australia: A qualitative study

ISSUE ADDRESSED

People from Sudanese background are more likely to be diagnosed with type 2 diabetes (T2D) as compared to the general population. In recent years, there has been an increase in the number of migrants from Sudan to Australia. However, there is a dearth of research exploring the perceptions and experiences of self-management strategies for diabetes among this migrant Sudanese population residing in Australia. This study aims to explore these experiences and perceptions as well as to identify cultural aspects related to T2D self-management strategies for people from this migrant group.

METHODS

A qualitative study using semi-structured in-depth interviews with Sudanese participants (n = 12) living with T2D was conducted in Melbourne, Australia.

RESULTS

The thematic analysis found barriers to self-management of diabetes to include language differences, the burden of self-management, difficulties in accommodating traditional dietary practices in self-management, as well as the expectations of familial and social obligations. Enablers included positive relationships with health professionals, support networks, involvement in religion and adopting traditional remedies.

CONCLUSIONS

This study found cultural considerations, such as incorporating traditional dietary practices and familial obligations into self-management, to be the most significant influence for this group of Sudanese participants in the way they managed their diabetes.

SO WHAT

This study highlights the need for culturally appropriate provision of health services and resources for Sudanese people with T2D while recognising the value placed on traditional food choices. Importantly, the collectivist Sudanese culture must be considered for any future development and implementation of health promotion strategies.

The effect of migration on the incidence and mortality of bloodstream infection: a Danish register-based cohort study

OBJECTIVES

To investigate bloodstream infection (BSI) related to migrant status by comparing the incidence and mortality in migrants with that in non-migrants.

METHODS

In this register-based cohort study we linked a cohort of migrants and non-migrants with a bacteraemia database covering two regions in Denmark. We included first-time BSI between January 2000 and December 2015 in individuals ≥18 years. Migrants were categorized according to status: refugees or family-reunified migrants. Incidence rate ratio and mortality rate ratio were analysed using Poisson regression.

RESULTS

We identified 493 080 non-migrants, of which 3405 had BSI, and 80 740 migrants with 576 cases; of the latter, 40 222 were family-reunified migrants with 226 cases and 40 518 were refugees with 350 cases. Refugees had a higher risk of BSI than non-migrants (adjusted IRR 1.19, 95%CI 1.01-1.40). Family-reunified migrants and refugees had a higher risk of Gram-negative BSIs (adjusted IRR 1.23, 95%CI 1.00-1.51 and 1.57, 95%CI 1.32-1.86), respectively, and a lower risk of Gram-positive BSIs (adjusted IRR 0.65, 95%CI 0.51-0.83 and 0.77, 95%CI 0.63-0.95), respectively, compared to non-migrants. Originating from Southeast Asia and the Pacific was associated with an increased risk of BSI compared to non-migrants (adjusted IRR 1.26, 95%CI 1.07-1.49). We found no differences in the adjusted 30-day or 90-day mortality according to migrant status.

CONCLUSIONS

Vulnerability towards BSI differs according to migrant status. Refugees had a higher risk of BSI overall. Both refugees and family-reunified migrants had a higher incidence of Gram-negative BSI than non-migrants. Similarly, migrants from Southeast Asia and the Pacific had a higher risk of BSI than non-migrants.

Patterns of multimorbidity and demographic profile of latent classes in a Danish population-A register-based study

Background

Multimorbidity is an increasing public health concern and is associated with a range of further adverse outcomes. Identification of disease patterns as well as characteristics of populations affected by multimorbidity is important for prevention strategies to identify those at risk.

Aim

The aim of the study was to identify and describe demographic characteristics of multimorbidity classes in three age groups (16–44 years, 45–64 years, and 65+ years).

Methods

Based on register information on 47 chronic diseases and conditions, we used latent class analysis to identify multimorbidity classes in a random sample of the Danish population (n = 470,794). Information on sociodemographic characteristics (age, sex, region of origin, educational level, employment status, and marital status) was obtained from registers and linked to the study population. Age- and sex-adjusted multinomial logistic regression models were used to examine associations between multimorbidity classes and sociodemographic characteristics.

Results

We identified seven classes among individuals in the age groups 45–64 years and 65+ years and five classes in the age group 16–44 years. Overall, the classes were similar in the three age groups, but varied in size, i.e. the class ‘No or few diseases’ was larger in the younger age group. The class ‘Many diseases’ (a class with both somatic diseases and mental illnesses) was only seen in individuals aged 45–64 years and 65+ years. There were social inequalities in odds of belonging to the multimorbidity classes compared to the healthier class. These social inequalities varied but were especially strong in the classes named ‘Many diseases’ and ‘Mental illness, epilepsy’.

Conclusion

The results of the study suggest that there are social inequalities in multimorbidity but that these inequalities are not universal to all types of multimorbidity. This supports that multimorbidity is diverse and should be prevented and treated accordingly.

Prevalence, incidence and mortality of type 1 and type 2 diabetes in Denmark 1996-2016

INTRODUCTION

The objective of this study was to give an overview of prevalence, incidence and mortality of type 1 (T1D) and type 2 diabetes (T2D) in Denmark, and their temporal trends.

RESEARCH DESIGN AND METHODS

We constructed a diabetes register from existing population-based healthcare registers, including a classification of patients as T1D or T2D, with coverage from 1996 to 2016. Using complete population records for Denmark, we derived prevalence, incidence, mortality and standardized mortality ratio (SMR).

RESULTS

The overall prevalence of diabetes at 2016 was 0.5% for T1D and 4.4% for T2D, with annual increases since 1996 of 0.5% for T1D and 5.5% for T2D. Incidence rates of T1D decreased by 3.5% per year, with increase for persons under 25 years of age and a decrease for older persons. T2D incidence increased 2.5% per year until 2011, decreased until 2014 and increased after that, similar in all ages. The annual decrease in mortality was 0.3% for T1D and 2.9% for T2D. The mortality rate ratio between T1D and T2D was 1.9 for men and 1.6 for women. SMR decreased annually 2% for T1D and 0.5% for T2D.

CONCLUSIONS

Incidence and prevalence of diabetes is increasing, but mortality among patients with diabetes in Denmark is decreasing faster than the mortality among persons without diabetes. T1D carries a 70% higher mortality than T2D.

Site-specific cancer risk in patients with type 2 diabetes: a nationwide population-based cohort study in Korea

BACKGROUND/AIMS

We aimed to evaluate site-specific cancer risk in diabetic patients and to investigate causal and temporal relationships by analyzing organ-specific cancer risk according to the duration of diabetes.

METHODS

Using a database provided by the Korean National Health Insurance Service, we conducted a retrospective, population-based cohort study of adults aged ≥ 30 years from January 2005 to December 2013. To verify the possibility of detection bias or reverse causation, we compared hazard ratios (HRs) for each cancer according to the following duration of diabetes: less than 6 months, 6 months to 3 years, and more than 3 years.

RESULTS

The incidence of overall cancer per 1,000 person-years was higher in patients with diabetes than in those without diabetes (20.36 vs. 10.83). The overall cancer risk according to the duration of diabetes was the highest within the first 6 months after diagnosis (HR, 2.03; 95% confidence interval [CI], 1.99 to 2.07), and the HR decreased with the duration of diabetes, ranging from 1.19 (95% CI, 1.18 to 1.21) between 6 months and 3 years to 1.12 (95% CI, 1.11 to 1.13) after 3 years. Both overall cancer risk and HR remained significantly higher in patients with diabetes than in those without diabetes. The risk for prostate cancer was higher in men with diabetes than in those without diabetes (HR, 1.12; 95% CI, 1.10 to 1.14). In women, the risk for endometrial cancer was significantly higher in patients with diabetes than in those without diabetes throughout the duration of diabetes.

CONCLUSION

The risk for stomach, colorectum, liver, pancreas, and kidney cancer appeared to be higher in patients with diabetes than in those without diabetes regardless of the sex or duration of diabetes.

A Qualitative Exploration of Facilitators and Barriers for Diabetes Self-Management Behaviors Among Persons with Type 2 Diabetes from a Socially Disadvantaged Area

BACKGROUND

Enhancing diabetes self-management (DSM) in patients with type 2 diabetes (T2D) can reduce the risk of complications, enhance healthier lifestyles, and improve quality of life. Furthermore, vulnerable groups struggle more with DSM.

AIM

To explore barriers and facilitators related to DSM in vulnerable groups through the perspectives of patients with T2D and healthcare professionals (HCPs).

METHODS

Data were collected through three interactive workshops with Danish-speaking patients with T2D (n=6), Urdu-speaking patients with T2D (n=6), and HCPs (n=16) and analyzed using systematic text condensation.

RESULTS

The following barriers to DSM were found among members of vulnerable groups with T2D: 1) lack of access to DSM support, 2) interference and judgment from one's social environment, and 3) feeling powerless or helpless. The following factors facilitated DSM among vulnerable persons with T2D: 1) a person-centered approach, 2) peer support, and 3) practical and concrete knowledge about DSM. Several barriers and facilitators expressed by persons with T2D, particularly those who spoke Danish, were also expressed by HCPs.

CONCLUSION

Vulnerable patients with T2D preferred individualized and practice-based education tailored to their needs. More attention should be paid to training HCPs to handle feelings of helplessness and lack of motivation among vulnerable groups, particularly among ethnic minority patients, and to tailor care to ethnic minorities.

Longitudinal Study of Diabetic Differences between International Migrants and Natives among the Asian Population

Migration presents a substantial social and public health issue. However, it is unclear whether diabetes is worse among Asian migrants than natives of South Korea over time. This longitudinal study investigated the nationwide population, including 2,680,495 adults aged 20 years and older (987,214 Asian migrants and 1,693,281 natives), who received health check-ups, using the Korean National Health Insurance Service data (2009-2015). Joinpoint regression was used to estimate the annual percentage change of diabetes, and multivariable logistic regression was used to examine differences in incident type 2 diabetes between Asian migrants and natives adjusting for age, sex, economic status, body mass index, smoking status, any alcohol use, and physical activity. The age-adjusted prevalence of diabetes increased among native men (from 8.8% in 2009 to 9.7% in 2015, APC=1.64, p<0.05) compared to Asian migrant men, and the age-adjusted prevalence of diabetes increased among native women (from 6.0% in 2009 to 6.7% in 2015, APC=1.88, p<0.05) compared to Asian migrant women. In the multivariate analyses, Asian migrants were less likely to get type 2 diabetes than natives (odds ratio, 0.82; 95% CI, 0.78 to 0.86) between the first and last health check-ups. However, the odds ratio for developing type 2 diabetes was 1.15 (95% CI, 1.10 to 1.20) among low-income levels compared to high-income levels, regardless of whether they were Asian migrants or natives. The results could help to establish a new strategy for prevention, treatment, and management of diabetes among the Asian population.

The UCL-Lancet Commission on Migration and Health: the health of a world on the move

With one billion people on the move or having moved in 2018, migration is a global reality, which has also become a political lightning rod. Although estimates indicate that the majority of global migration occurs within low-income and middle-income countries (LMICs), the most prominent dialogue focuses almost exclusively on migration from LMICs to high-income countries (HICs). Nowadays, populist discourse demonises the very same individuals who uphold economies, bolster social services, and contribute to health services in both origin and destination locations. Those in positions of political and economic power continue to restrict or publicly condemn migration to promote their own interests. Meanwhile nationalist movements assert so-called cultural sovereignty by delineating an us versus them rhetoric, creating a moral emergency.

In response to these issues, the UCL-Lancet Commission on Migration and Health was convened to articulate evidence-based approaches to inform public discourse and policy. The Commission undertook analyses and consulted widely, with diverse international evidence and expertise spanning sociology, politics, public health science, law, humanitarianism, and anthropology. The result of this work is a report that aims to be a call to action for civil society, health leaders, academics, and policy makers to maximise the benefits and reduce the costs of migration on health locally and globally. The outputs of our work relate to five overarching goals that we thread throughout the report.

First, we provide the latest evidence on migration and health outcomes. This evidence challenges common myths and highlights the diversity, dynamics, and benefits of modern migration and how it relates to population and individual health. Migrants generally contribute more to the wealth of host societies than they cost. Our Article shows that international migrants in HICs have, on average, lower mortality than the host country population. However, increased morbidity was found for some conditions and among certain subgroups of migrants, (eg, increased rates of mental illness in victims of trafficking and people fleeing conflict) and in populations left behind in the location of origin. Currently, in 2018, the full range of migrants’ health needs are difficult to assess because of poor quality data. We know very little, for example, about the health of undocumented migrants, people with disabilities, or lesbian, gay, bisexual, transsexual, or intersex (LGBTI) individuals who migrate or who are unable to move.

Second, we examine multisector determinants of health and consider the implication of the current sector-siloed approaches. The health of people who migrate depends greatly on structural and political factors that determine the impetus for migration, the conditions of their journey, and their destination. Discrimination, gender inequalities, and exclusion from health and social services repeatedly emerge as negative health influences for migrants that require cross-sector responses.

Third, we critically review key challenges to healthy migration. Population mobility provides economic, social, and cultural dividends for those who migrate and their host communities. Furthermore, the right to the highest attainable standard of health, regardless of location or migration status, is enshrined in numerous human rights instruments. However, national sovereignty concerns overshadow these benefits and legal norms. Attention to migration focuses largely on security concerns. When there is conjoining of the words health and migration, it is either focused on small subsets of society and policy, or negatively construed. International agreements, such as the UN Global Compact for Migration and the UN Global Compact on Refugees, represent an opportunity to ensure that international solidarity, unity of intent, and our shared humanity triumphs over nationalist and exclusionary policies, leading to concrete actions to protect the health of migrants.

Fourth, we examine equity in access to health and health services and offer evidence-based solutions to improve the health of migrants. Migrants should be explicitly included in universal health coverage commitments. Ultimately, the cost of failing to be health-inclusive could be more expensive to national economies, health security, and global health than the modest investments required.

Finally, we look ahead to outline how our evidence can contribute to synergistic and equitable health, social, and economic policies, and feasible strategies to inform and inspire action by migrants, policy makers, and civil society. We conclude that migration should be treated as a central feature of 21st century health and development. Commitments to the health of migrating populations should be considered across all Sustainable Development Goals (SDGs) and in the implementation of the Global Compact for Migration and Global Compact on Refugees. This Commission offers recommendations that view population mobility as an asset to global health by showing the meaning and reality of good health for all. We present four key messages that provide a focus for future action.

Multimorbidity and mortality thereof, among non-western refugees and family reunification immigrants in Denmark - a register based cohort study

Background

The prevalence of multimorbidity, defined by having two or more chronic diseases, is increasing in many Western countries. Simultaneously, the migrant population in Western countries has increased, making up a growing proportion of European populations. This study aims i) to determine the quantity and quality of multimorbidity patterns among refugees and family reunification immigrants from non-Western countries compared to Danish-born, and ii) to compare the mortality burden among those with multimorbidity in the two groups.

Methods

Through the Danish Immigration Service, we conducted a historically prospective cohort study. We identified a total of 101,894 adult migrants who were sub-categorised into refugees and family reunification immigrants, and matched them to a Danish-born comparison group 1:6 on age and sex. Through the Danish National Patient Registry, we obtained information on all in- and outpatient data on hospitalised and ambulatory patients. To assess multimorbidity we used Charlson Comorbidity Index based on ICD-10 codes, together with ICD-10 diagnostic categories for psychiatric disease. We used Cox regression analysis to calculate risk of multimorbidity and risk of mortality in people with multimorbidity.

Results

Overall refugees had higher risk of multimorbidity compared to Danish-born, while family reunification immigrants had a lower risk. When adjusting for civil status and mean income, the risk was lower for all migrant groups compared to Danish-born. Risk of mortality in people with multimorbidity, was lower for all migrant groups, compared to Danish-born.

Conclusion

Refugees are an at-risk group for multimorbidity, however, mortality among those with multimorbidity is lower in all migrant groups compared to Danish-born.

Small scale migration along the interoceanic highway in Madre de Dios, Peru: an exploration of community perceptions and dynamics due to migration

Background

Madre de Dios, a southern state in the Peruvian Amazon basin, has experienced rapid development as well as an influx of migrants since the construction of the Interoceanic Highway (IOH) connecting Brazil, Bolivia, and the Peruvian coast. We explored perceptions of migration and development in up to eight communities along the IOH in Madre de Dios following construction of the highway.

Methods

We conducted a multiple methods study involving focus group (FG) discussions and interviews with key informants (KIs) in eight communities in Madre de Dios. The data was used to develop and apply a survey on demographics, financial, personal, social, human, and physical capital in four communities between February 2014 and March 2015.

Results

We conducted 12 FGs and 34 KI interviews. A total of 522 people participated in the survey. Comparing migrants (those who had moved to the area after construction of the IOH) and non-migrants, we found no difference in food security or access to health services. The majority (67.6%) of respondents from both groups reported that illness was their primary threat to well-being. Non-migrants owned more land than migrants (p < 0.001), were more likely to have piped water directly in their home (p = 0.046), and were more likely to participate in community groups (p = 0.012). Looking at perceptions about migrants, KIs and FGs discussed both positive perceptions of migrants (increased cultural exchange and new technology) and negative perceptions (increased drugs and alcohol in their communities and a lack of investment in the community). Both migrants and non-migrants reported trusting the local government more than the national government.

Conclusions

Although we hypothesized that migrants would have decreased access to food, water, health services, and land relative to non-migrants, our results show that the only significant differences were in land ownership and water access. Efforts to improve community infrastructure should be carried out at the local level and focus on improving issues reported by both groups, such as potable water, sewage, and increased access to health services. Furthermore, an emphasis on community cohesion, ensuring land rights, and increasing long-term job opportunities should help ease tensions between migrants and non-migrants.

Systematic health screening of refugees after resettlement in recipient countries: a scoping review

CONTEXT

Health screening of refugees after settlement in a recipient country is an important tool to find and treat diseases. Currently, there are no available reviews on refugee health screening after resettlement.

METHODS

A systematic literature search was conducted using the online Medical Literature Analysis and Retrieval System ('MEDLINE') database. Data extraction and synthesis were performed according to the PRISMA statement.

RESULTS

The search retrieved 342 articles. Relevance screening was conducted on all abstracts/titles. The final 53 studies included only original scientific articles on health screening of refugees conducted after settlement in another country. The 53 studies were all from North America, Australia/New Zealand and Europe. Because of differences in country policies, the screenings were conducted differently in the various locations. The studies demonstrated great variation in who was targeted for screening and how screening was conducted. The disease most frequently screened for was tuberculosis; this was done in approximately half of the studies. Few studies included screening for mental health and non-infectious diseases like diabetes and hypertension.

CONCLUSION

Health screening of refugees after resettlement is conducted according to varying local policies and there are vast differences in which health conditions are covered in the screening and whom the screening is available to.
