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 Status and Utilization of Healthcare Services Among Venezuelan Immigrants in Peru.

BACKGROUND: In general, migrants in illegal situations encounter a greater barrier to accessing medical care because of their migration status due to not having the required documentation to be able to obtain insurance in the receiving country. OBJECTIVE: To evaluate the association between migration status and the use of health services in the Venezuelan population residing in Peru. METHODS: Data from the second Survey Directed to the Venezuelan Population Residing in Peru (ENPOVE) of 2022 were analyzed. The dependent variable was use of health services in the last month. The exposure variable was migration status (legal/illegal). Generalized linear models of the Poisson family with link log function were used to obtain crude and adjusted prevalence ratios (aPR), for potential confounding variables. Additionally, we evaluated the association of interest, stratified by gender. FINDINGS: Data from 1569 migrants were analyzed. Participants with illegal migration status represented 32.4% (men: 24.3%; women: 36.7%); likewise, 58.1% did not use health services. Illegal migration status was associated with lower health care use (aPR: 0.75; 95%CI: 0.61-0.92). Likewise, after stratifying by sex, the association was maintained only in male migrants (aPR: 0.53; 95%CI: 0.39-0.82) but not in women (aPR: 0.84; 95%CI: 0.67-1.05). CONCLUSION: 58.1% of Venezuelan migrants in Peru did not seek medical attention despite having health problems. Having an illegal immigration status leads to a lower probability of using these services, especially in men.

COVID-19 and Vaccination: Knowledge, Attitudes and Practices of People Working on Illegal Gold Mining Sites in French Guiana.

INTRODUCTION: French Guiana is a French territory bordering Brazil and Suriname where the COVID-19 pandemic has severely strained the French Guianese health system. The people working on illegal gold mining sites in French Guiana, also known as garimpeiros, are mainly of Brazilian origin. Their health conditions are precarious, they live under the radar of the surveillance system and therefore, assessment of their health is quite challenging.. The objective of this study was to describe their knowledge, attitudes and practices regarding COVID-19 and vaccination against this infection. METHODS: We conducted an international multicenter cross-sectional survey between 1 March 2022 and 30 April 2022 in French Guiana and Suriname, using a structured questionnaire. RESULTS: Eighty persons were included, 95.0% of whom were Brazilian. Most had good general knowledge of COVID-19. Antibiotic prophylaxis had been practiced by 10.0% of participants. Forty-three people thought they had been infected with COVID-19 (53.8%). Self-medication was frequent, often with antibiotics (32.6%, mostlychloroquine, ivermectin or azithromycin) and most had not consulted a physician for symptoms of COVID-19. A majority (62.5%) had received at least one dose of vaccine. Those who were ever tested for COVID-19 were the most likely to be vaccinated (PR = 1.98, p = 0.009). CONCLUSIONS: Garimpeiros have a good level of knowledge about COVID-19 but the high consumption of antibiotics raises concerns about the selection of resistant bacteria. The vaccination rate was higher than that of the Guianese population. The most vaccinated individuals were those who had already taken a COVID test suggesting that these individuals had more exposure to the disease, were more health conscious, or had easier access to health centers.

Sexual and reproductive health of migrant women and girls from the Northern Triangle of Central America.

Objective: To understand the sexual and reproductive health (SRH) experiences of migrant women and girls of reproductive age (15-49 years) from the Northern Triangle of Central America (El Salvador, Guatemala and Honduras) during their journey to the United States. Methods: A descriptive, qualitative research design included 39 in-depth interviews with migrant women and unaccompanied migrant girls from El Salvador, Guatemala and Honduras from January to June 2022. Participants were recruited using purposive sampling. Interviews were transcribed, coded and analyzed using thematic analysis. Results: Migrant women and girls lack information and resources to manage their SRH during migration. The SRH of those traveling with smugglers is compromised due to their limited access to menstrual pads, water and sanitation services; the risks of transactional sex and sexual violence; the high risk of sexually transmitted infections; the inability to report sexual violence; the lack of access to SRH and prenatal services; and limited knowledge about their sexual and reproductive rights. Conclusions: There is a significant need for improved interventions during the predeparture phase of migration to inform migrant women and girls about the SRH risks they may encounter and to provide information and resources to support their SRH throughout their journey. Special attention should be directed towards trying to reach girls and women who will travel with smugglers.

Post-Rape Experiences of Undocumented Mexican Women in the U.S.-Mexico Border Region: A Critical Ethnography.

Introduction: Numerous undocumented immigrant women in the United States have survived rape, and many have experienced physical and psychological consequences. Although rape disclosure can facilitate early intervention and improve health outcomes, most undocumented immigrant women do not disclose rape, and little is known about their post-rape experiences. Methods: This critical ethnography explored the post-rape experiences of undocumented immigrant women of Mexican (UIWM) origin living in the U.S. Mexico border region. Data collection and analysis were guided by Carspecken's framework for critical qualitative research. Six women, who identified as UIWM participated in the study. Each was interviewed using a semistructured approach. Results: Interview data revealed three domains: Glimpses of Support, Barrier After Barrier, and Overcoming. In accordance with Carspecken's framework, a theoretical lens was applied to these domains. The application of Feminist Intersectional Theory and Standpoint Theory united the domains into the theme Struggling to Heal. Conclusion: This study suggests that the marginalization of these survivors detrimentally impacts their post-rape experiences and describes the intersections of multiple forces on their experiences, including the cultural and sociopolitical context of the border region. This study lays the foundation for future research aimed at mitigating disclosure and help-seeking barriers for this marginalized group.

Undocumented Mexican mothers of children with autism: navigating the health care and educational service systems.

In the field of education and health care, researchers and educators attempt to close the diagnosis/identification and service gaps that persist for low-resourced, underrepresented families with children with autism. One group of families particularly difficult to engage in research and interventions is undocumented immigrant families. We know little about whether these families are obtaining a timely diagnosis or services for their children with autism. This study addresses how undocumented Mexican immigrant mothers of children with autism navigate the special education and health care systems, challenges they face in doing so, and the helpers who assist in navigating the process. Six undocumented Mexican immigrant mothers of children with autism participated in one-on-one interviews. Participants were interviewed in a semi-structured format and transcription, coding, and final analysis were conducted in Spanish using analytic software. Three broad themes emerged during the content analysis process: (1) immigration driving force and experience, (2) autism-specific challenges, and (3) autism-specific helpers. Additionally, a case study of each participant is presented and discussed.

Data-driven approach in a compartmental epidemic model to assess undocumented infections.

Nowcasting and forecasting of epidemic spreading rely on incidence series of reported cases to derive the fundamental epidemiological parameters for a given pathogen. Two relevant drawbacks for predictions are the unknown fractions of undocumented cases and levels of nonpharmacological interventions, which span highly heterogeneously across different places and times. We describe a simple data-driven approach using a compartmental model including asymptomatic and pre-symptomatic contagions that allows to estimate both the level of undocumented infections and the value of effective reproductive number R t from time series of reported cases, deaths, and epidemiological parameters. The method was applied to epidemic series for COVID-19 across different municipalities in Brazil allowing to estimate the heterogeneity level of under-reporting across different places. The reproductive number derived within the current framework is little sensitive to both diagnosis and infection rates during the asymptomatic states. The methods described here can be extended to more general cases if data is available and adapted to other epidemiological approaches and surveillance data.

COVID-19 Underreporting in Brazil among Patients with Severe Acute Respiratory Syndrome during the Pandemic: An Ecological Study.

Underreporting of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection is a global problem and might hamper Coronavirus Disease (COVID-19) epidemiological control. Taking this into consideration, we estimated possible SARS-CoV-2 infection underreporting in Brazil among patients with severe acute respiratory syndrome (SARS). An ecological study using a descriptive analysis of the SARS report was carried out based on data supplied by the Influenza Epidemiological Surveillance Information (SIVEP)-Flu (in Brazilian Portuguese, Sistema de Vigilância Epidemiológica da Gripe) in the period between January 2015 and March 2021. The number of SARS cases and related deaths after infection by SARS-CoV-2 or Influenzae was described. The estimation of underreporting was evaluated considering the relative increase in the number of cases with undefined etiological agent comparing 2020 to 2015−2019; and descriptive analysis was carried out including data from January−March/2021. In our data, SARS-CoV-2 infection and the presence of SARS with undefined etiological agent were associated with the higher number of cases and deaths from SARS in 2020/2021. SARS upsurge was six times over that expected in 2020, according to SARS seasonality in previous years (2015−2019). The lowest possible underdiagnosis rate was observed in the age group < 2 y.o. and individuals over 30 y.o., with ~50%; while in the age groups 10−19 and 20−29 y.o., the rates were 200−250% and 100%, respectively. For the remaining age groups (2−5 and 5−9 y.o.) underreporting was over 550%, except for female individuals in the age group 2−5 y.o., in which a ~500% rate was found. Our study described that the SARS-CoV-2 infection underreporting rate in Brazil in SARS patients is alarming and presents different indices, mainly associated with the patients' age groups. Our results, mainly the underreporting index according to sex and age, should be evaluated with caution.

Everyday Acts of Resistance: Mexican, Undocumented Immigrant Children and Adolescents Navigating Oppression With Mentor Support.

Study aims were to examine oppression in education among Mexican immigrant youth with undocumented status and how mentors and other adults helped them resist oppression. Qualitative, narrative one-on-one interviews were conducted with 17 Mexican immigrant young adults with undocumented or DACA status in the U.S. Participants provided retrospective accounts from childhood through older adolescence. Analyses revealed critical junctures in which participants experienced oppression: (1) developmental milestones and school events, (2) college application process, (3) unforeseen life events, and (4) incidents of racial discrimination. Mentors and other adults helped participants to resist oppression through advocacy, social capital efforts, role modeling, and emotional, instrumental, and financial support. This study fills gaps in the literature on mentoring and immigrant youth who are undocumented.

The New System of Mexican Migration: The Role of Entry Mode-Specific Human and Social Capital.

Between 2000 and 2020, undocumented migration declined, temporary labor migration rose, and legal permanent residents arrived at a steady pace-together creating a new system of Mexico-U.S. migration based on the circulation of legal temporary workers and permanent residents. Drawing on data from the U.S. Department of Homeland Security and the Mexican Migration Project, we specify multinomial event-history models to predict the likelihood of departure on first and later trips via four entry categories: no documents, noncompliant tourist visas, temporary work visas, and legal residence visas. The models reveal how the accumulation of entry mode-specific social and human capital powered a system of undocumented migration that emerged between 1965 and 1985, and how that system deteriorated from 1985 to 2000. After 2000, employers took advantage of new visa categories to recruit legal temporary workers, leading to the accumulation of migration-related human and social capital specific to that mode of entry and the emergence of a new system of Mexico-U.S. migration.

A southwestern grassroots community coalition of undocumented Mexican community members: A location for bridging resources and sociopolitical action.

The current nativist and ethnocentric policies and rhetoric put forward in the United States have compromised the safety of undocumented Hispanic/Latinx Americans. Many in these communities abstain from overt action toward change. Nonetheless, there are examples of community members who embrace the narrative "undocumented and unafraid." Through in-depth individual interviews and focus groups, we qualitatively examined how undocumented Mexican community coalition members (N = 10), focused on enacting socio-political change on behalf of their predominantly Mexican southwestern community, understood the role of their group as a venue for bridging resources and social action. Findings centered on three specific broad themes: (1) Meeting Community Needs: A Disconnection from Resources; (2) Community Coalition as a Space for Bridging Resources; and (3) Community Coalition as a Space for Activism and Social Change.

The mechanism and pattern of injuries of undocumented immigrants crossing the Texas-Mexico border along the Rio Grande Valley.

BACKGROUND: Apprehensions of undocumented immigrants in the Rio Grande Valley sector of the U.S.-Mexico border have grown to account for nearly half of all apprehensions at the border. The purpose of this study is to report the prevalence, mechanism, and pattern of traumatic injuries sustained by undocumented immigrants who crossed the U.S.-Mexico border at the Rio Grande Valley sector over a span of 5 years and were treated at a local American College of Surgeons verified Level II trauma center. METHODS: A retrospective chart review was conducted from January 2014 to December 2019. Demographics, comorbidities, injury severity score (ISS), mechanism of injury, anatomical part of the body affected, hospital and ICU length of stay (LOS), and treatment costs were analyzed. Descriptive statistics for demographics, injury location and cause, and temporal trends are reported. The impact of ISS or surgical intervention on hospital LOS was analyzed using an analysis of covariance (ANCOVA). RESULTS: Of 178 patients, 65.2% were male with an average age of 31 (range 0-67) years old and few comorbidities (88.8%) or social risk factors (86%). Patients most commonly sustained injuries secondary to a border fence-related incident (33.7%), fleeing (22.5%), or motor vehicle accident (16.9%). There were no clear temporal trends in the total number of patients injured, or in causes of injury, between 2014 and 2019. The majority of patients (60.7%) sustained extremity injuries, followed by spine injuries (20.2%). Border fence-related incidents and fleeing increased risk of extremity injuries (Odds ratio (OR) > 3; p < 0.005), whereas motor vehicle accidents increased risk of head and chest injuries (OR > 4; p < 0.004). Extremity injuries increased the odds (OR: 9.4, p < 0.001) that surgery would be required. Surgical intervention was common (64%), and the median LOS of patients who underwent surgery was 3 days more than those who did not (p < 0.001). CONCLUSION: In addition to border fence related injuries, undocumented immigrants also sustained injuries while fleeing and in motor vehicle accidents, among others. Extremity injuries, which were more likely with border fence-related incidents, were the most common type. This type of injury often requires surgical intervention and, therefore, a longer hospital stay for severe injuries.

Skeletal evidence of structural violence among undocumented migrants from Mexico and Central America.

OBJECTIVES: We examine the prevalence and sociodemographic risk factors of skeletal indicators of stress in forensic samples of undocumented migrants from Mexico and Central America. MATERIALS AND METHODS: Cranial and dental remains of 319 migrants recovered in the Arizona and Texas borderlands were assessed for porotic hyperostosis (PH), cribra orbitalia (CO), and linear enamel hypoplasias (LEH). Logistic regression models for each condition were estimated to test for associations with biological sex, age, recovery location, and whether individuals were identified. Additional models estimated for a subsample of identified migrants included region of origin, residential context, and community indigeneity. RESULTS: The full sample shows moderate crude prevalence of CO (9.6%) and LEH (34.1%), and a high prevalence of PH (49.6%). Significantly higher odds of PH are associated with being male (2.16 times higher), unidentified (1.89 times higher), and recovered in Arizona (3.76 times higher). Among identified migrants, we fail to find associations significant at the p < 0.05 level between skeletal stress and all sociodemographic variables except age. DISCUSSION: The factors associated with PH may be related to influences on decisions to migrate and diversity among migrant sending regions. The skeletal evidence for early life stress is generally consistent with common public health concerns among impoverished communities in the region. The lesions themselves are viewed as embodied risk of physiological disturbance when resource access is structured by higher-level social, economic, and political forces. Forensic anthropologists would benefit from increased sensitivity to embodied structural violence among the vulnerable individuals and communities they serve.

Snapshot Models of Undocumented Immigration.

Accurately estimating the size of the undocumented immigrant population is a critical component of assessing the health and security risks of undocumented immigration to the United States. To provide one such estimate, we use data from the Mexican Migration Project (MMP), a study that includes samples of undocumented Mexican immigrants to the United States after their return to Mexico. Of particular interest are the departure and return dates of a sampled migrant's most recent sojourn in the United States, and the total number of such journeys undertaken by that migrant household, for these data enable the construction of data-driven undocumented immigration models. However, such data are subject to an extreme physical bias, for to be included in such a sample, a migrant must have returned to Mexico by the time of the survey, excluding those undocumented immigrants still in the United States. In our analysis, we account for this bias by jointly modeling trip timing and duration to produce the likelihood of observing the data in such a "snapshot" sample. Our analysis characterizes undocumented migration flows including single-visit migrants, repeat visitors, and "retirement" from circular migration. Starting with 1987, we apply our models to 30 annual random snapshot surveys of returned undocumented Mexican migrants accounting for undocumented Mexican migration from 1980 to 2016. Scaling to population quantities and supplementing our analysis of southern border crossings with estimates of visa overstays, we produce lower bounds on the total number of undocumented immigrants that are much larger than conventional estimates based on U.S.-based census-linked surveys, and broadly consistent with the more recent estimates reported by Fazel-Zarandi, Feinstein, and Kaplan.

Mental Health Needs of an Emerging Latino Community.

Over the last decade, Baltimore has become a non-traditional sanctuary city, receiving an unprecedented influx of Latino immigrants, mostly from Central America's Northern Triangle, who are often fleeing violence in their home countries. This study explored the nature and frequency of healthcare utilization for mental health problems among uninsured/uninsurable Latinos who received outpatient care between 2012 and 2015 through an academic hospital-affiliated program that covers primary and specialty services to uninsured patients without regard to documentation status. Encounters for mental health disorders were the most common category, accounting for 14.88% of all visits. Mood (78%) and anxiety disorders (16%) were the most prevalent mental health diagnoses. The most frequent reason to seek care was symptom, signs, and ill-defined conditions (37.47%), and within this subgroup, pain was the leading cause of seeking care (88%), which may indicate high rates of somatization of mental health distress. This study presents a unique opportunity to explore the burden and nature of mental health needs among a population for which healthcare information is rarely attainable and highlights the need for culturally competent screening mechanisms and interventions to address the stressors faced by emergent communities.

Receptionists, doctors, and social workers: Examining undocumented immigrant women's perceptions of health services.

In this paper, we examine the attitudes, experiences, and perceptions of health care among unauthorized immigrant women in Philadelphia, Pennsylvania. Research on health care utilization among undocumented immigrants usually focuses on barriers to securing health care access, but little attention has been paid to how these barriers shape patients' experiences. Patients' experiences are important because they affect persistence in care seeking, adherence to treatment regimens, and self-reported health. Drawing from interviews with undocumented Mexican women, we find that receptionists, staff, and social workers play an important role in shaping women's perceptions of health care. In contrast to previous research which finds that negative experiences with providers lead undocumented immigrants to withdraw from seeking medical services, without fail, our respondents persisted and sought care elsewhere. This strategy ensured that all women eventually found care with which they were satisfied, but sometimes after significant delays.

Spatial Distributions of Oxygen Stable Isotope Ratios in Tap Water From Mexico for Region of Origin Predictions of Unidentified Border Crossers.

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ18 O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.

Lethal Violence and Migration in Mexico: An Analysis of Internal and International Moves.

We analyze the effect of homicide in Mexico on patterns and processes of internal and international migration. Linking municipal-level homicide rates from 1990 through 2018 with data from the Mexican Migration Project, we estimate a series of multinomial discrete time event history models to assess the effect that exposure to lethal violence has on the likelihood of migration within Mexico and to the United States without documents. Statistical estimates indicate that the homicide rate negatively predicts the likelihood of taking a first undocumented trip to the United States but positively predicts the likelihood of taking a first trip within Mexico. Among those undocumented migrants who have already taken a first U.S. trip, lethal violence also negatively predicts the likelihood of taking a second undocumented trip. Among returned internal migrants whose first trip was to a Mexican destination, the odds of taking a first U.S. trip were also negatively predicted by the municipal homicide rate. We conclude that rising violence in Mexico is not a significant driver of undocumented migration to the United States. Instead it contributes to the decline in undocumented out-migration observed since 2007, in combination with the rising age of those at risk of migration and the growing access of Mexicans to legal entry visas.

Analizamos el efecto de homicidio en México sobre patrones y procesos de migración interna y internacional. Conectando tasas de homicidio municipales desde 1990 a 2018 con datos del Proyecto Mexicano de Migración, estimamos una serie de modelos multinomiales de tiempo discreto para evaluar el efecto de la violencia mortal sobre la probabilidad de migrar dentro de México o hacia los Estados Unidos sin documentos. Estimaciones indican que la tasa de homicidio predice negativamente la probabilidad de tomar un primero viaje a los Estandos uniods per predice positivamente la probabilidad de tomar un primero viaje dentro de México. Entre los migrantes indocumentados quien ya se han hecho un primer viaje a los Estados Unidos, violencia mortal también predice negativamente la probabilidad de hacer un segundo viaje indocumentado. Entre migrantes retornados de un primer viaje dentro de México, la probabilidad de hacer un primero viaje indocumentado a los EE. UU. también están predicidos negativamente por la tasa de homicide municipal. Concluimos que el crecimiento de violencia mortal en México no es una causa de la migración indocumentada a los Estados Unidos. Al contrario, la violencia contribuya a la la disminución en migración indocumentada observada desde 2007, en combinación con el aumento de la edad promedia y el acceso creciente a visas legales para entrar los EE. UU.

Salud de migrantes internacionales en situación irregular: una revisión narrativa de iniciativas / Health of international migrants in an irregular situation: a narrative review of initiatives

RESUMEN La población migrante internacional en situación irregular (MISI) suele encontrarse en una condición de particular vulnerabilidad que impacta en su salud, y sumado a esto, enfrenta múltiples barreras que dificultan e incluso impiden su acceso a los servicios de salud. La presente revisión tiene por objetivo identificar y describir iniciativas que abordan el acceso a los servicios de salud en población MISI. Para ello, se realizó una revisión narrativa en PubMed, Embase, Health Systems Evidence, Cochrane, LILACS y Scielo entre julio y agosto de 2017. Se encontraron 787 artículos, de los cuales se incluyeron 26, los que dieron cuenta de 31 iniciativas. La mayoría de estas iniciativas se sitúan en América Septentrional (61%), Asia Sudoriental (10%) y Europa Septentrional (10%); se refieren mayoritariamente a servicios de nivel primario (48%) y terciario (52%), servicios de urgencia/emergencia (39%), brindan accesibilidad administrativa (65%) y financiera (45%), y responden a necesidades en la etapa de «destino¼ del proceso migratorio (97%). Se puede concluir que existen diversas iniciativas que abordan la problemática del acceso a los servicios de salud de la población MISI. No obstante, no se hallaron iniciativas dirigidas a la rehabilitación y salud sexual; contacto y calidad; perspectiva de género y competencia cultural en salud.

ABSTRACT The population of international migrants in an irregular situation (IMIS) often finds itself in a condition of particular vulnerability that has an impact on its health. Additionally to this, these migrants face multiple barriers that hinder or even impede their access to health services. This review aims at identifying and describing initiatives that address access to health services in the IMIS population. To this end, a narrative review was conducted in PubMed, Embase, Health Systems Evidence, Cochrane, LILACS, and Scielo, between July and August of 2017. Seven hundred and eighty-seven (787) articles were found, of which 26 have been included, accounting for 31 initiatives. Most of these initiatives are located in North America (61%), South-East Asia (10%), and Northern Europe (10%). They refer mostly to primary (48%) and tertiary (52%) services; urgency/emergency services (39%); provide administrative (65%) and financial accessibility (45%); and respond to needs at the "destination" stage of the migration process (97%). It can be concluded that there are several initiatives that deal with the problems faced by the IMIS population in terms of access to healthcare services. However, no initiatives were found aimed at rehabilitation and sexual health; contact and quality, gender perspective, and cultural competence in health.
