"No Papers, No Treatment": a scoping review of challenges faced by undocumented immigrants in accessing emergency healthcare.

BACKGROUND: Undocumented immigrants face many obstacles in accessing emergency healthcare. Legal uncertainties, economic constraints, language differences, and cultural disparities lead to delayed medical care and thereby exacerbate health inequities. Addressing the healthcare needs of this vulnerable group is crucial for both humanitarian and public health reasons. Comprehensive strategies are needed to ensure equitable health outcomes. OBJECTIVE: This study aimed to identify and analyze the barriers undocumented immigrants face in accessing emergency healthcare services and the consequences on health outcomes. METHODS: We used a scoping review methodology that adhered to established frameworks. Utilizing MEDLINE/PubMed, Embase, Web of Science, PsychoInfo, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), we identified 153 studies of which 12 focused on the specific challenges that undocumented immigrants encounter when accessing emergency healthcare services based on the inclusion and exclusion criteria. RESULTS: The results show that undocumented immigrants encounter significant barriers to emergency healthcare, including legal, financial, linguistic, and cultural challenges. Key findings were the extensive use of emergency departments as primary care due to lack of insurance and knowledge of alternatives, challenges faced by health professionals in providing care to undocumented migrants, increased hospitalizations due to severe symptoms and lack of healthcare access among undocumented patients, and differences in emergency department utilization between irregular migrants and citizens. The findings also serve as a call for enhanced healthcare accessibility and the dismantling of existing barriers to mitigate the adverse effects on undocumented immigrants' health outcomes. CONCLUSIONS: Undocumented immigrants' barriers to emergency healthcare services are complex and multifaceted and therefore require multifaceted solutions. Policy reforms, increased healthcare provider awareness, and community-based interventions are crucial for improving access and outcomes for this vulnerable population. Further research should focus on evaluating the effectiveness of these interventions and exploring the broader implications of healthcare access disparities.

Sexual and Reproductive Health Rights and Service Use among Undocumented Migrants in the EU: A Systematic Literature Review.

Most EU member states fail to provide essential sexual and reproductive health services to undocumented migrants, a vulnerable population facing limited access, utilization, and worse health-related outcomes. This study systematically reviewed the literature on access to and use of these services, as well as related health, economic, and migratory outcomes for undocumented migrants in the EU-EFTA region. The systematic review is reported based on the PRISMA 2020 checklist and includes 37 studies published between 2017 and 2024. Included studies were based upon original quantitative, qualitative, or mixed-methods data; conducted in one or more European countries; and published in one or more of the following languages: English, Spanish, French, Portuguese, or Romanian. A quality assessment was conducted using the CASP checklist for qualitative studies and the NHLBI Study Quality Assessment Tools for quantitative studies. The findings revealed numerous access barriers, including refusal of care, lack of knowledge about national healthcare schemes, bureaucratic hurdles, and affordability issues. Even when care was available, stigma, fear of deportation, socio-economic precarity, and abuse further hindered utilization. These barriers contributed to generally worse reproductive health outcomes for undocumented migrants in Europe, though the findings may not generalize to all EU-EFTA countries.

Ethical and Epistemological Implications of Conducting Ethnographic Fieldwork as a Researcher-cum-Clinician in Brussels, Belgium.

We draw on ethnographic fieldwork conducted in Brussels (Belgium) on the health care experiences of undocumented migrants. We explore the implications of the double position of the ethnographer, who is both a researcher and a practicing doctor. We describe how the intimate knowledge the ethnographer-cum-clinician holds about the health care system influenced and shaped the data collection, analysis and subsequent policy recommendations. We examine the ethical dilemmas in conducting research from an engaged position about care practices toward vulnerable populations in one's own professional field. We conclude with recommendations on how to challenge and interrupt complexities faced by multi-positioned ethnographers.

Healthcare Utilization and Chronic Disease Management for Non-Medicaid-Eligible Patients in a City-Wide Safety-Net Healthcare Access Program.

BACKGROUND: In 2019, New York City (NYC) launched NYC Care (NYCC), a healthcare access program through NYC Health + Hospitals (H + H) for individuals who are ineligible for federally funded health insurance programs or cannot purchase insurance through the State Marketplace, predominantly undocumented individuals. OBJECTIVE: To examine the sociodemographic characteristics, healthcare use patterns, and chronic disease quality measures for diabetes mellitus (DM) and hypertension among NYCC patients compared with Medicaid patients seen at NYC H + H. DESIGN: Observational study. PARTICIPANTS: Adults aged 18 years and older enrolled in NYCC (N = 83,003) or Medicaid (N = 512,012) as of January 1, 2022. Patients were included if they had at least one visit between January 1, 2021, and December 31, 2021. MAIN MEASURES: Sociodemographic characteristics, healthcare use patterns, and quality measures for DM and hypertension. KEY RESULTS: NYCC patients (n = 83,003) were, on average, older, more likely to be Hispanic with Spanish as their preferred language, had more comorbidities, and had more primary care (adjusted incidence rate ratio 2.75 [95% confidence interval 2.71, 2.80]) and specialty care (2.22 [2.17, 2.26]) visits compared to Medicaid patients (n = 512,012). Rates of emergency department visits were similar between the two groups (1.02 [1.00, 1.04]), but NYCC patients had relatively fewer hospitalizations (0.64 [0.62, 0.67]). NYCC patients with DM or hypertension had higher rates of having a documented hemoglobin A1c or blood pressure in 2022, respectively, and clinically similar rates of chronic disease control (mean difference in hemoglobin A1c - 0.05 [- 0.09, - 0.01] in patients with DM and mean difference in blood pressure - 0.38 [- 0.67, - 0.10]/ - 0.64 [- 0.82, - 0.46]) compared with Medicaid patients. CONCLUSIONS: NYCC effectively enrolled a large number of uninsured participants and provided them with healthcare access similar to that of Medicaid patients. Future studies should evaluate the impact of NYCC enrollment on healthcare utilization and disease outcomes.

The changing context of Postings and Transfer with subsequent postings: A frontline perspective from India.

The deployment of the health workforce, carried out through initial and subsequent Posting and Transfer (PT) is a key element of health workforce management. However, the focus of the currently available PT literature is mostly on subsequent PT, and the distinction between initial and subsequent PT has received little research attention. Drawing on this gap, in this paper, we examine how doctors experience their subsequent PT compared to their initial postings in two states in India. The distinctions have been drawn using the prism of six norms that we developed as evidence for implied policy in the absence of documented policy. This mixed methods study used in depth interviews of doctors and key informants, with job histories providing quantitative data from their accounts of their PT experience. Based on the interviews of these front-line doctors and other key policy actors, this paper brings to light key differences between initial and subsequent postings as perceived by the doctors: compared to initial postings, where the State demands to meet service needs dominated, in subsequent postings, doctors exercised greater agency in determining outcomes, with native place a central preoccupation in their choices. Our analysis provides a nuanced understanding of PT environment through this shift in doctor's perceptions of their own position and power within the system, with a significant change in their behaviour of doctors in subsequent PT compared to their initial postings. The paper brings to light the changing behaviour of doctors with subsequent PT, providing a deeper understanding of PT environment, expanding the notion of PT beyond the simple dichotomy between service needs and doctors' requests.

The Health Status of Undocumented Immigrants from Asian Countries in the United States: A Scoping Review and Recommendations for Future Directions.

Immigrants from Asian countries are the fastest-growing undocumented population in the United States (U.S.), yet not much is known about their health. This scoping review identifies the nature and extent of scientific literature on the health of undocumented Asian immigrants in the U.S. We conducted a comprehensive search of six electronic databases in 2024. Inclusion criteria were empirical articles written in English, published in peer-reviewed scientific journals from 2010 to 2024, and focused on a health outcome or health-related issue involving undocumented Asian immigrants. Results are summarized narratively. We identified 13 peer-reviewed publications. Nine studies were quantitative, and four were qualitative. Eight studies were conducted in California; two studies used national secondary data sources. Studies were mixed in their research focus. They covered a range of health outcomes and issues, such as mental health (n = 4), health services and access (n = 2), contraceptive use (n = 1), COVID-19 (n = 2), and HIV (n = 1). Three studies measured self-rated health alongside other conditions, such as disability, health insurance coverage, chronic health conditions, and obesity. Scholarship on the health of undocumented Asian immigrants is a growing research area. Given the small number of studies identified, future research with larger diverse samples, more robust methodology, and greater topical variety are warranted to understand the health of this population better and reduce potential inequities.

Prevalence and factors associated with undocumented children under-five in Haiti.

BACKGROUND: Despite many efforts to provide children with legal existence over the last decades, 1 in 4 children under the age of 5 (166 million) do not officially exist, with limited possibility to enjoy their human rights. In Latin America and the Caribbean, Haiti has one of the highest rates of undocumented births. This study aimed to analyze the prevalence and the determinant factors of undocumented childhood in Haiti. METHODS: For analysis of undocumented childhood and related socioeconomic determinants, data from the 2016/17 Haiti demographic and health survey were used. The prevalence and the associated factors were analyzed using descriptive statistics and the binary logistic regression model. RESULTS: The prevalence of undocumented childhood in Haiti was 23% (95% CI: 21.9-24.0) among children under-five. Among the drivers of undocumented births, mothers with no formal education (aOR = 3.88; 95% CI 2.21-6.81), children aged less than 1 year (aOR = 20.47; 95% CI 16.83-24.89), children adopted or in foster care (aOR = 2.66; 95% CI 1.67-4.24), children from the poorest regions like "Artibonite" (aOR = 2.19; 95% CI 1.63-2.94) or "Centre" (aOR = 1.51; 95% CI 1.09-2.10) or "Nord-Ouest" (aOR = 1.61; 95% CI 1.11-2.34), children from poorest households (aOR = 6.25; 95% CI 4.37-8.93), and children whose mothers were dead (aOR = 2.45; 95% CI 1.33-4.49) had higher odds to be undocumented. CONCLUSION: According to our findings, there is an institutional necessity to bring birth documentation to underprivileged households, particularly those in the poorest regions where socioeconomic development programs are also needed. Interventions should focus on uneducated mothers who are reknown for giving birth outside of medical facilities. Therefore, an awareness campaign should be implemented to influence the children late-registering behavior.

Migration and Mental Health in Two Contemporary Memoirs.

This article examines two autobiographical texts that address the relationship between migration and struggles with mental health: Karla Cornejo Villavicencio's The Undocumented Americans (2021) and Dina Nayeri's The Ungrateful Refugee: What Immigrants Never Tell You (2020). Both memoirs help bring mental health issues to light in situations of precarity, and the texts indicate that it is not just the experience of physical dislocation that may cause or exacerbate struggles with mental health, but the disconnect from other people, from citizenship, and the nation itself. Nayeri and Cornejo Villavicencio do not focus on narratives of recovery or healing but provide space for the experiences of other undocumented migrants trying to navigate the European asylum system or difficulties in obtaining American citizenship. The article argues that the two authors use their experiences of migration and mental illness for greater advocacy purposes with regard to human rights. The struggles with mental health present in the two memoirs intertwine with the treatment of undocumented migrants as described by the two authors, going beyond the personal experience of mental health, or illness, connecting it with migration practices and policies in the United States and Europe.

Everyday Violence: Immigration Enforcement, COVID-19, and Depression among Undocumented Young Adults in California.

Background: The immigration enforcement system has significant effects on the health of immigrants, their families, and society. Exposure to the immigration enforcement system is linked to adverse mental health outcomes, which may have been exacerbated by sustained immigration enforcement activities during the COVID-19 pandemic. Objectives: This study was conducted to investigate the association between exposure to immigration enforcement and the mental health of undocumented young adults in California during the COVID-19 pandemic. Methods: Data are from the COVID-19 BRAVE (Building Community Raising All Immigrant Voices for Health Equity) Study, a community-engaged cross-sectional survey of the impacts of the COVID-19 pandemic on undocumented immigrants in California. A total of 366 undocumented immigrants between 18 and 39 years of age completed the online survey, which was conducted between September 2020 and February 2021. Multivariable logistic regression models were fit to examine the association between immigration enforcement exposure and depression. Results: Almost all participants (91.4%) disclosed exposure to the immigration enforcement system, with most reporting an average of 3.52 (SD=2.06) experiences. Multivariate analyses revealed that an increase in the immigration enforcement exposure score was significantly associated with higher odds of depression (adjusted odds ratio [aOR]=1.24; 95% confidence interval [CI]: 1.10, 1.40), and women were 92% more likely to report depression than were men (aOR=1.92; 95% CI: 1.12, 3.31). Those who reported deportation fears were significantly more likely to be depressed (aOR=1.24; 95% CI: 1.10, 1.40). Conclusions: Researchers should consider the mental health implications of a punitive immigration enforcement system, and policymakers should examine the impacts of immigration policies on local communities.

Dignity of Work and at Work: The Relationship between Workplace Dignity and Health among Latino Immigrants during the COVID-19 Pandemic.

Latino immigrants living in the United States were highly vulnerable to the health and economic consequences brought on by the COVID-19 pandemic. We use the conceptual framing of workplace dignity, worth that is acknowledged based on performance of job responsibilities, to explore Latino immigrants' experiences during the early months of the pandemic. A qualitative study was conducted with La Clínica del Pueblo (La Clínica), a community health center serving low-income Latino immigrants. From June to December 2020, we conducted in-depth video interviews with 29 Latino immigrant clients to explore pandemic-related challenges, including workplace changes, discriminatory experiences, and effects on health. We conducted thematic analysis using Dedoose software. Nearly half of participants were undocumented immigrants. Most participants were unemployed or underemployed due to the pandemic and 26-49 years of age; one-third were still working, and one-quarter were 50 years or older. About half were cisgender women and two were transgender women. Employed participants experienced a lack of dignity through being socially isolated and stigmatized at work; receiving no compensation for their extra labor or for sick leave; and experiencing discriminatory labor practices. Unemployed participants experienced a lack of dignity in being the first to lose their jobs without government support; losing self-esteem; and not being rehired. Participants associated denial of dignity with worsening health conditions and increased anxiety and depression. Our study suggests that denial of workplace dignity-through job loss, underemployment, and poor working conditions-is linked to adverse health outcomes for Latino immigrants. More research should recognize workplace dignity as an important social determinant of health.

Pathway Programs That Support Students From Immigrant Backgrounds in Becoming Physicians.

Pathways programs are critical to promoting access and success for careers in healthcare for students from immigrant backgrounds. Three cases are presented that demonstrate the successful elements of pathways programs. Excellence in pediatrics requires the inclusion of talent from immigrant communities. Community capacity building and systems level change can be achieved through coliberatory practice of mutual action, investment, and benefit. Navigation, mentorship, and structural support for educational, social, and monetary capital are key components of pathways programs.

Perinatal mortality among pregnant undocumented migrants in Norway 1999-2020: A register-based population study.

BACKGROUND: Irregular legal status is a recognized health risk factor in the context of migration. However, undocumented migrants are rarely included in health surveys and register studies. Adverse perinatal outcomes are especially important because they have long-term consequences and societal risk factors are modifiable. In this study, we compare perinatal outcomes in undocumented migrants to foreign-born and Norwegian-born residents, using a population-based register. METHODS: We included women 18-49 years old giving birth to singletons as registered in the Medical Birth Registry of Norway from 1999 to 2020. Women were categorized as 'undocumented migrants' (without an identity number), 'documented migrants' (with an identity number and born abroad), and 'non-migrants' (with an identity number and born in Norway). The main outcome was perinatal mortality, i.e., death of a foetus ≥ gestational week 22, or neonate up to seven days after birth. We used log-binominal regression to estimate the association between legal status and perinatal mortality, adjusting for several maternal pre-gestational and gestational factors. Direct standardization was used to adjust for maternal region of origin. ETHICAL APPROVAL: Regional Ethical Committee (REK South East, case number 68329). RESULTS: We retrieved information on 5856 undocumented migrant women who gave birth during the study period representing 0.5% of the 1 247 537 births in Norway. Undocumented migrants had a relative risk of 6.17 (95% confidence interval 5.29 ̶7.20) of perinatal mortality compared to non-migrants and a relative risk of 4.17 (95% confidence interval 3.51 ̶4.93) compared to documented migrants. Adjusting for maternal region of origin attenuated the results slightly. CONCLUSION: Being undocumented is strongly associated with perinatal mortality in the offspring. Disparities were not explained by maternal origin or maternal health factors, indicating that social determinants of health through delays in receiving adequate care and factors negatively influencing gestational length may be of importance.

Exploring risky health behaviors and vulnerability to sexually transmitted diseases among transnational undocumented labor migrants from Bangladesh: a qualitative study.

BACKGROUND: In Bangladesh, remittances constitute a substantial portion of the country's foreign exchange earnings and serve as a primary source of income. However, a considerable number of Bangladeshi citizens reside overseas without proper documentation, exposing them to significant challenges such as limited access to healthcare and socioeconomic opportunities. Moreover, their irregular migration status often results in engaging in risky health behaviors that further exacerbate their vulnerability. Hence, this study aimed to investigate the risky health behavior and HIV/STI susceptibility of Bangladeshi irregular international migrants residing across the globe with undocumented status. METHODS: Using a qualitative Interpretative Phenomenological Approach (IPA), 25 illegal migrants were interviewed who are currently living illegally or returned to their home country. The author used a thematic approach to code and analyze the data, combining an integrated data-driven inductive approach with a deductive approach. Concurrent processing and coding were facilitated by employing the Granheim model in data analysis. RESULTS: The study identified four risky health behaviors among irregular Bangladeshi migrants: hazardous living conditions, risky jobs, suicidal ideation, and tobacco consumption. Additionally, the authors found some HIV/STI risk behavior among them including engaging in unprotected sex, consuming alcohol and drugs during sexual activity, and having limited access to medical facilities. CONCLUSIONS: The findings of this study can be used by health professional, governments, policymakers, NGOs, and concerned agencies to develop welfare strategies and initiatives for vulnerable undocumented migrant workers.

"We want our freedom back, that's our only need": a qualitative study of health and social needs among asylum seekers and undocumented migrants crossing the borders from Belarus to Lithuania.

Background: The influx of undocumented migrants and asylum seekers into Lithuania, particularly during the COVID-19 pandemic, presents unique public health challenges. This study employs the Social Determinants of Health framework to explore the healthcare and social needs of this vulnerable population. Methods: In May 2022, we carried out a qualitative study through semi-structured interviews with asylum seekers across four centers in Lithuania. Employing both purposive and snowball sampling techniques, we selected participants for our investigation. The study comprised 21 interviews-19 conducted in Arabic and 2 in English-with durations ranging between 20 and 40 min each. We audio-recorded all interviews, transcribed them verbatim, and subsequently performed a thematic analysis using Atlas.ti software. This process of design and analysis strictly followed the principles of thematic analysis as outlined by Braun and Clarke, guaranteeing methodological precision and rigor. Findings: 21 interviews revealed critical insights into the healthcare access challenges, mental health issues, and social integration barriers faced by the participants. Key themes included 'Healthcare Needs and the Impact of the COVID-19 Pandemic 'and 'Social needs and Aspirations Amidst Pandemic-Induced Uncertainty '. The findings highlight the multifaceted healthcare and social needs of asylum seekers, juxtaposed against significant barriers they face. Access to medical services is hindered by long waiting times and financial constraints, especially for specialized care such as dental services. Communication issues during medical appointments due to language barriers and the lack of gender-specific healthcare, such as access to gynecological services, further exacerbate the challenges. Additionally, the COVID-19 pandemic introduces hurdles such as limited testing, isolation measures, language-specific information barriers, and insufficient social distancing practices. Mental health has emerged as a critical concern, with asylum seekers reporting significant stress and emotional exhaustion due to uncertainty and restrictive living conditions. Social needs extend to delayed asylum application processes, inconsistent language education opportunities, inadequate clothing, and nutrition that lacks cultural sensitivity, and living conditions characterized by overcrowding and insufficient facilities. The restricted freedom of movement within asylum seeking centres severely impacts their psychological well-being, underscoring a deep longing for autonomy and a better life despite the myriad of challenges faced. Discussion: The study illustrates the complex interplay between migration, health, and social factors in the context of a global pandemic. It highlights the need for culturally sensitive healthcare services, mental health support, and structured language education programs. Offering educational avenues alongside language courses for children and adults is essential for fostering social inclusion and securing economic prosperity. Addressing the challenge of language barriers is of utmost importance, as these barriers significantly impede undocumented migrants' and asylum seekers employment opportunities and their access to crucial services. The findings emphasized immigration as a health determinant and underscored the importance of inclusive health policies and advocacy for undocumented migrants and asylum seekers' rights and needs. Conclusion: There is an urgent need for comprehensive policies and practices that are grounded in the principles of equity, compassion, and human rights. Additionally, advocating for practice adaptations that are culturally sensitive, linguistically inclusive, and responsive to the unique challenges faced by undocumented migrants and asylum seekers. As global migration continues to rise, these findings are crucial for informing public health strategies and social services that cater to the diverse needs of this vulnerable population.

The mental health of migrants living in limbo: A mixed-methods systematic review with meta-analysis.

The number of forcibly displaced people has more than doubled over the past decade. Many people fleeing are left in limbo without a secure pathway to citizenship or residency. This mixed-methods systematic review reports the prevalence of mental disorders in migrants living in limbo, the association between limbo and mental illness, and the experiences of these migrants in high income countries. We searched electronic databases for quantitative and qualitative studies published after January 1, 2010, on mental illness in precarious migrants living in HICs and performed a meta-analysis of prevalence rates. Fifty-eight articles met inclusion criteria. The meta-analysis yielded prevalence rates of 43.0 % for anxiety disorders (95 % CI 29.0-57.0), 49.5 % for depression (40.9-58.0) and 40.8 % for posttraumatic stress disorder (30.7-50.9). Having an insecure status was associated with higher rates of mental illness in most studies comparing migrants in limbo to those with secure status. Six themes emerged from the qualitative synthesis: the threat of deportation, uncertainty, social exclusion, stigmatization, social connection and religion. Clinicians should take an ecosocial approach to care that attends to stressors and symptoms. Furthermore, policymakers can mitigate the development of mental disorders among migrants by adopting policies that ensure rapid pathways to protected status.

"Because We Are Afraid": voices of the undocumented in a new immigrant destination in the United States.

The purpose of this study is to explore immigrants' perceptions of their daily lives in a state with anti-immigrant policies in the United States. Using snowball sampling, researchers recruited a sample of 30 Latino immigrants in southwest Montana. The research team conducted semi-structured interviews in Spanish and analyzed the data using thematic analysis. We identified four themes: difficulty accessing healthcare, frustration over the inability to obtain driver's licenses, challenges related to employment, and desire to make a life in Montana. Fear permeated all topics. Lack of documentation presents complex economic, health, and social challenges that prevent immigrants from fully integrating into their communities. These are exacerbated in states that employ anti-immigrant policies. As Western states continue to experience growth in immigrant populations, it is critical to develop policies to support integration and equitable access to health and social services.

The Psychological Health Symptoms of DACA Recipients: A Systematic Review at the Ten-Year Mark of the Program.

The purpose of this systematic review was to identify the mental health symptoms endorsed by DACA recipients. This study included qualitative and quantitative original, peer-reviewed articles related to mental health or psychological state or wellbeing of DACA recipients. Articles were abstracted from PsychInfo, PubMed, and GoogleScholar. The results included a total of fifteen articles, which were divided into qualitative and quantitative findings. The qualitative articles had a common theme of endorsement of depressive symptoms and negative affect associated to changes in familial and financial responsibilities and living in a difficult sociopolitical climate in the United States. The quantitative articles identified lower odds or symptom severity of depression and other internalizing symptoms compared to undocumented individuals. This summary review was limited by the ample exclusion of access to health care studies among DACamented individuals, which could have provided a broader picture about the health and accessibility for DACA recipients. Despite the limitations, this review identifies DACA as a policy that allows this group to improve their social function and quality of life compared to undocumented individuals but still endorse high levels of negative affect related to perceived challenging sociopolitical atmospheres.

Cardiovascular risk and access to primary care: Comparisons among Chinese documented and undocumented immigrants.

AIMS: The aim of this study was to examine main risk factors of undocumented Chinese migrants living in Italy when compared with Chinese migrants registered with National Health Service (NHS). METHODS: A cohort of 3435 Chinese first-generation immigrants living in Prato underwent blood pressure (BP) measurement and blood tests. Hypertension was diagnosed for BP ≥ 140/90 mmHg at 2 visits, and/or antihypertensive drug use; type 2 diabetes (T2DM) for fasting glucose ≥ 126 mg/dL at 2 visits, and/or use of hypoglycemic drugs; hypercholesterolemia (HC) for cholesterol ≥ 240 mg/dL and/or statins use. Subjects diagnosed with hypertension, T2DM, or HC unaware of their condition were considered newly diagnosed. Comparisons were performed using multivariable adjusted logistic regression analysis. RESULTS: A large proportion of Chinese migrants were undocumented (1766, 51 %); newly diagnoses of risk factors were performed especially among undocumented migrants; registration with NHS was associated with higher level of awareness for hypertension and T2DM and with 6 times higher rate of treatment for T2DM. Only a small minority of subjects with high cholesterol were treated with statins. CONCLUSIONS: Undocumented immigrants had high prevalence of risk factors with lower levels of awareness than migrants registered with the NHS. Health policies targeting this hard-to-reach population needs to be improved.
