Does living in a neighbourhood with others of the same ethnic background contribute to health of Canada's immigrant children?

OBJECTIVES

To understand how neighbourhood characteristics affect the health of immigrant children in Canadian cities. We question whether the health of children is influenced by immigrants living in enclaves of people with similar ethnic and socio-economic backgrounds.

METHODS

Two datasets were used: the New Canadian Children and Youth Study (NCCYS) and Statistics Canada census data. The NCCYS comprises children from Hong Kong, the Philippines and Mainland China living in Canada's largest cities. Logistic regression was used to examine the influence of neighbourhood ethnic concentrations and mean income on health.

RESULTS

Girls were more likely to be reported to have excellent health compared to boys, as were children living in neighbourhoods with lower mean parental education. Children from Hong Kong were less likely to have excellent health compared to the reference group. For the Mainland Chinese group only, there was an inverse relationship between reported health status and the concentration of people from the same ethnic background in the neighbourhood.

CONCLUSION

The health of children from different ethnic backgrounds is influenced by different social and economic factors. In practice and in research, "immigrants" and even broadly defined cultural groupings, such as "Asian immigrants", should be considered as heterogeneous.

Antenatal depression in a multi-ethnic, community sample of Canadian immigrants: psychosocial correlates and hypothalamic-pituitary-adrenal axis function

OBJECTIVES

Immigrant women living in Canada present with higher rates of prenatal depressive symptomatology than Canadian-born women; however, the associated psychosocial correlates remain understudied. Antenatal depression and stress negatively affect maternal health and infant development, in part through changes in maternal hypothalamic-pituitary-adrenal (HPA) axis activity. We aimed to examine the factors associated with prenatal depressive symptoms, including altered HPA axis function, in an ethnically diverse community sample of Canadian immigrant women.

METHODS

Seventy-eight pregnant immigrant women were recruited from the community at 19 weeks' gestation and provided information on health, mood, stressful life events (SLEs), and social support. Fifty-seven of these women also provided saliva samples for measurement of the cortisol awakening response and nighttime cortisol levels.

RESULTS

Seventeen per cent of the sample had a high level of prenatal depressive symptoms, and these women reported more perceived stress, more somatic symptoms, lower social support, and were less often working or attending school during pregnancy. Controlling for wake time, parity, and region of origin, high levels of prenatal depressive symptoms were associated with elevated nighttime cortisol levels, whereas SLEs were not associated with any measures of HPA axis activity.

CONCLUSIONS

High levels of prenatal depressive symptoms are common in immigrant women living in Canada, and are associated with identifiable factors. Preliminary evidence suggests a similar pattern of HPA axis activity characterizing depressive symptomatology in this subpopulation as previously seen in clinically depressed patients.

Factors associated with degree of atopy in Latino children in a nationwide pediatric sample: the Genes-environments and Admixture in Latino Asthmatics (GALA II) study

BACKGROUND

Atopy varies by ethnicity, even within Latino groups. This variation might be due to environmental, sociocultural, or genetic factors.

OBJECTIVE

We sought to examine risk factors for atopy within a nationwide study of US Latino children with and without asthma.

METHODS

Aeroallergen skin test responses were analyzed in 1830 US Latino subjects. Key determinants of atopy included country/region of origin, generation in the United States, acculturation, genetic ancestry, and site to which subjects migrated. Serial multivariate zero-inflated negative binomial regressions stratified by asthma status examined the association of each key determinant variable with the number of positive skin test responses. In addition, the independent effect of each key variable was determined by including all key variables in the final models.

RESULTS

In baseline analyses African ancestry was associated with 3 times (95% CI, 1.62-5.57) as many positive skin test responses in asthmatic participants and 3.26 times (95% CI, 1.02-10.39) as many positive skin test responses in control participants. Generation and recruitment site were also associated with atopy in crude models. In final models adjusted for key variables, asthmatic patients of Puerto Rican (exp[β] [95% CI], 1.31 [1.02-1.69]) and mixed (exp[β] [95% CI], 1.27 [1.03-1.56]) ethnicity had a greater probability of positive skin test responses compared with Mexican asthmatic patients. Ancestry associations were abrogated by recruitment site but not region of origin.

CONCLUSIONS

Puerto Rican ethnicity and mixed origin were associated with degree of atopy within US Latino children with asthma. African ancestry was not associated with degree of atopy after adjusting for recruitment site. Local environment variation, represented by site, was associated with degree of sensitization.

The influences of immigration on health information seeking behaviors among Korean Americans and Native Koreans

Korean Americans (KAs) have low screening rates for cancer and are often not well informed about their chronic diseases. Reduced access to health-related information is one reason for gaps in knowledge and the widening health disparities among minority populations. However, little research exists about KAs' health information seeking behaviors. Guided by the Structural Influence Model, this study examines the influence of immigration status on KAs' trust in health information sources and health information seeking behaviors. Cross-sectional surveys were conducted in the Washington, D.C., metropolitan area as well as in the Gwangju metropolitan city in South Korea during 2006-2007. Two hundred and fifty-four KAs and 208 native Koreans who were 40 years of age or older completed the surveys. When comparing native Koreans to KAs, we found KAs were 3 times more likely to trust health information from newspapers or magazines (odds ratio [OR] = 3.13; 95% confidence interval [CI] = 1.49-6.54) and 11 times more likely to read the health sections of newspapers or magazines (OR = 11.35; 95% CI = 3.92-32.91) in multivariate adjusted models. However, they were less likely to look for health information from TV (OR = 0.29; 95% CI = 0.12-0.72) than native Koreans. Our results indicate that immigration status has profound influences on KAs' health information seeking behaviors. Increasing the availability of reliable and valid health information from printed Korean language magazines or newspapers could have a positive influence on increasing awareness and promoting screening behaviors among KAs.

The migration process as a stress factor in pregnant immigrant women in Spain

Spain has seen a significant increase of the immigrant population in the past two decades. There are 5.6 million registered immigrants in this country, and 63% of them range in age between 16 and 41 years; 47% of the immigrant population are women. This situation requires additional health care, particularly as it pertains to the sexual and reproductive health of female immigrants. The objective of our study was to determine if there were differences between women of Spanish origin and immigrant women in terms of obstetric outcomes (obstetric history, gestational age at end of gestation, and at delivery) and various psychological variables during the immediate postpartum period. This was a cross-sectional study-we evaluated 30 women of Spanish origin and 30 immigrant women during the immediate postpartum period. During the 4 months after delivery, we proceeded to gather perinatal data for the study participants from their health records, partograms, and nursing assessment notes. Additionally, and following the immediate postpartum period, participants filled out the Stress Perception and Stress Vulnerability Questionnaires, as well as the Optimism Scale. Immigrant women have greater perception of stress (p = .00) and vulnerability to stress (p = .001) than do Spanish women. However, no group differences were found in obstetric variables.

Depressive symptoms of midlife Latinas: effect of immigration and sociodemographic factors

Immigrant Latinas may have different cultural attitudes toward menopause and aging, and may experience higher levels of distress associated with adaptation to their new environment. The purpose of this secondary analysis was to describe the frequency of depressive symptoms experienced by premenopausal Latinas (40-50 years of age) living in the United States and compare Latinas born in the US with immigrant Latinas on stress and sociodemographic factors that influence depressive symptom experience. Analysis was conducted on a subsample of 94 self-identified Latinas who participated in a longitudinal study and completed the Center for Epidemiological Studies-Depression (CES-D) scale at enrollment and 6 months. Immigrant Latinas had a significantly higher CES-D (14.4 ± 11.1) than US-born Latinas (10.0 ± 7.9) and the difference remained at 6 months. There was no difference in age, body mass index (BMI), self-report of general health, or perceived stress. Higher BMI, work-related stress, and insufficient income for essential daily needs were associated with depressive symptom scores in immigrant Latinas. High BMI and less education were associated with depressive symptom scores in the US-born Latinas.

Acculturative stress and diminishing family cohesion among recent Latino immigrants

This study investigates a theorized link between Latino immigrants' experience of acculturative stress during their two initial years in the United States (US) and declines in family cohesion from pre- to post-immigration contexts. This retrospective cohort study included 405 adult participants. Baseline assessment occurred during participants' first 12 months in the US. Follow-up assessment occurred during participants' second year in the US. General linear mixed models were used to estimate change in family cohesion and sociocultural correlates of this change. Inverse associations were determined between acculturative stress during initial years in the US and declines in family cohesion from pre-immigration to post-immigration contexts. Participants with undocumented immigration status, those with lower education levels, and those without family in the US generally indicated lower family cohesion. Participants who experienced more acculturative stress and those without family in the US evidenced a greater decline in family cohesion. Results are promising in terms of implications for health services for recent Latino immigrants.

Blood pressure in Afghan male immigrants to Denmark

PURPOSE

Immigration from a Third-World society to a Western society can be associated with higher blood pressure and salt sensitivity. We therefore tested whether immigrants from Afghanistan to Denmark compared with non-immigrant Danes exhibit a (i) higher 24-h ambulatory blood pressure (24-h ABP) and (ii) blunted renin response to a change in salt intake.

METHODS

Twenty-four-hour ABP was measured in 40 men of Afghan (Afghans) and 40 men of Danish (Danes) origin. Each group was divided into young (20-30 years, n = 20) and middle aged (40-60 years, n = 20). A 3-day low (70 mmol per 24-h) and a 3-day high (250 mmol per 24-h) salt intake were in addition instituted in subgroups of the young groups (n = 18).

RESULTS

Young and middle-aged Afghans exhibited a lower 24-h mean arterial pressure (24-h MAP) than the same respective age groups of Danes (83 ± 1 versus 90 ± 1 mm Hg, P<0·05, and 89 ± 2 versus 100 ± 1 mm Hg, P<0·05). 24-h ABP did not change in any of the young groups during increased salt intake, whereas the Danes exhibited a greater decrease in plasma renin activity (PRA) (P<0·05). Plasma noradrenaline (PNA ) was significantly higher among the young Afghans.

CONCLUSIONS

Afghan immigrants to Denmark exhibit a lower 24-h ABP than Danes. In young Afghans, PRA is less sensitive to changes in salt intake, while PNA is higher and may reflect their lower systolic blood pressure and/or arterial pulse pressure. Whether these hormonal differences can explain the lower 24-h ABP in Afghans should be further explored.

The Hispanic Paradox and older adults' disabilities: is there a healthy migrant effect?

The "Hispanic Paradox" suggests that despite rates of poverty similar to African Americans, Hispanics have far better health and mortality outcomes, more comparable to non-Hispanic White Americans. Three prominent possible explanations for the Hispanic Paradox have emerged. The "Healthy Migrant Effect" suggests a health selection effect due to the demands of migration. The Hispanic lifestyle hypothesis focuses on Hispanics' strong social ties and better health behaviors. The reverse migration argument suggests that the morbidity profile in the USA is affected when many Hispanic immigrants return to their native countries after developing a serious illness. We analyzed data from respondents aged 55 and over from the nationally representative 2006 American Community Survey including Mexican Americans (13,167 U.S. born; 11,378 immigrants), Cuban Americans (314 U.S. born; 3,730 immigrants), and non-Hispanic White Americans (629,341 U.S. born; 31,164 immigrants). The healthy migrant effect was supported with SES-adjusted disability comparable between Mexican, Cuban and non-Hispanic Whites born in the USA and all immigrants having lower adjusted odds of functional limitations than U.S. born non-Hispanic Whites. The reverse migration hypothesis was partially supported, with citizenship and longer duration in the USA associated with higher rates of SES-adjusted disability for Mexican Americans. The Hispanic healthy life-style explanation had little support in this study. Our findings underline the importance of considering nativity when planning for health interventions to address the needs of the growing Hispanic American older adult population.

Immigration and Prosecutorial Discretion

Immigration has become an increasingly salient national issue in the US, and the Department of Justice recently increased federal efforts to prosecute immigration offenses. This shift, however, relies on the cooperation of US attorneys and their assistants. Traditionally federal prosecutors have enjoyed enormous discretion and have been responsive to local concerns. To consider how the centralized goal of immigration enforcement may have influenced federal prosecutors in regional offices, we review their prosecution of immigration offenses in California using over a decade's worth of data. Our findings suggest that although centralizing forces influence immigration prosecutions, individual US attorneys' offices retain distinct characteristics. Local factors influence federal prosecutors' behavior in different ways depending on the office. Contrary to expectations, unemployment rates did not affect prosecutors' willingness to pursue immigration offenses, nor did local popular opinion about illegal immigration.

Coming ‘Home’ to (post)Colonial Medicine: Treating Tropical Bodies in Post-War Britain

While investment and popular enthusiasm have fuelled significant growth in the history of medicine since the 1980s, it remains by some metrics well outside of the historical mainstream. Yet developments in the history of medicine could offer traction to historians more generally. Through its close critical attention to power, embodiment and hegemonic institutions and knowledges, the history of medicine also presents a unique perspective from which to interrogate ‘postcolonialism’. Here, post-war British examples demonstrate the potential of a medical and postcolonial lens for historians exploring policy making, immigration or identity. In this period, civil servants, biomedical researchers, policy makers, and publics including migrants actively shaped medical and governmental responses to an apparently novel phenomenon: the mass migration to Britain of its former tropical subjects. Postcolonial analysis uncovers new models of community, and highlights the importance of the late twentieth-century and the post-imperial city as sites of historiographic and theoretical development.

Migration challenges among Zimbabwean refugees before, during and post arrival in South Africa

BACKGROUND

Zimbabweans are immigrating to South Africa with a commonly cited reason being economic opportunities. Prospects of finding employment may be a significant reason to leave behind family, friends, and community, sources that buffer and offer social support against life's challenges. Currently, there is a dearth of research examining the motivators for Zimbabweans immigrating and the experiences encountered along the way and after arrival in South Africa. Such research is essential as large numbers of Zimbabweans may be at risk for emotional and physical trauma during this process.

METHODS

Two gender specific focus group discussions, each lasting 90-minutes and consisting of homeless Zimbabwean refugees, were conducted in the Limpopo Province of South Africa. A semi-structured interview assessed for experiences in and reasons for leaving Zimbabwe, as well as experiences en-route and within South Africa. Discussions were audio-recorded, transcribed, and analyzed using consensual qualitative research and a constant comparison qualitative method.

RESULTS

Three temporal themes were identified and included challenges and trauma experienced in Zimbabwe (pre-migration), during the immigration journey (mid-migration), and upon arrival in South Africa (post-migration). While there were some experiential differences, Zimbabwean men and women shared numerous traumatic commonalities. In addition to the themes, three subthemes contributing to reasons for leaving Zimbabwe, two subthemes of negative and traumatic experiences incurred mid-migration, and two post-migration subthemes of challenges were identified.

CONCLUSIONS

Despite the difficulties encountered in their homeland, newly arrived Zimbabweans in South Africa may be exchanging old struggles for a new array of foreign and traumatic challenges. Reasons to immigrate and the psychological and physical toll of migration exacted at the individual and community levels are discussed. Recommendations advocating for culturally congruent mental health research, the training of culturally competent researchers and clinicians, and the development of policies that could influence the quality of life of Zimbabwean refugees are provided.

Depression, anxiety, and suicidal ideation among Chinese Americans: a study of immigration-related factors

The aim of this study was to identify anxiety, depression, and suicidal ideation disparities among Chinese Americans and how immigration-related factors affected the outcomes. We tried to explain the differences as a function of the Chinese culture. Data were derived from the National Latino and Asian American Study, the first national epidemiological survey of these populations in the United States. We used only the Chinese sample (N = 600) and focused on depressive disorder, anxiety disorder, and suicidal ideation. The United States-born Chinese and those Chinese who immigrated to the United States at 18 years or younger were at higher risk for lifetime depressive or anxiety disorders or suicidal ideation than were their China-born counterparts who arrived in the country at or after 18 years of age. For Chinese Americans, immigration-related factors were associated with depression and anxiety disorders and suicidal ideation. The higher prevalence of these disorders might be attributed to the psychological strains experienced by those who are at higher risk of cultural conflicts.

Native Competition and Low-Skilled Immigrant Inflows

This paper demonstrates that immigration decisions depend on local labor market conditions by documenting the change in low-skilled immigrant inflows in response to supply increases among the US-born. Using pre-reform welfare participation rates as an instrument for changes in native labor supply, I find that immigrants competing with native entrants systematically prefer cities with smaller supply shocks. The extent of the response is substantial: for each native woman working due to reform, 0.5 fewer female immigrants enter the local labor force. These results provide direct evidence that international migration flows tend to equilibrate returns across US local labor markets.

Health care usage among immigrants and native-born elderly populations in eleven European countries: results from SHARE

Differences in health care utilization of immigrants 50 years of age and older relative to the native-born populations in eleven European countries are investigated. Negative binomial and zero-inflated Poisson regression are used to examine differences between immigrants and native-borns in number of doctor visits, visits to general practitioners, and hospital stays using the 2004 Survey of Health, Ageing, and Retirement in Europe database. In the pooled European sample and in some individual countries, older immigrants use from 13 to 20% more health services than native-borns after demographic characteristics are controlled. After controlling for the need for health care, differences between immigrants and native-borns in the use of physicians, but not hospitals, are reduced by about half. These are not changed much with the incorporation of indicators of socioeconomic status and extra insurance coverage. Higher country-level relative expenditures on health, paying physicians a fee-for-service, and physician density are associated with higher usage of physician services among immigrants.

Minimum package for cross-border TB control and care in the WHO European region: a Wolfheze consensus statement

The World Health Organization (WHO) European region estimates that more than 400,000 tuberculosis (TB) cases occur in Europe, a large proportion of them among migrants. A coordinated public health mechanism to guarantee TB prevention, diagnosis, treatment and care across borders is not in place. A consensus paper describing the minimum package of cross-border TB control and care was prepared by a task force following a literature review, and with input from the national TB control programme managers of the WHO European region and the Wolfheze 2011 conference. A literature review focused on the subject of TB in migrants was carried out, selecting documents published during the 11-yr period 2001-2011. Several issues were identified in cross-border TB control and care, varying from the limited access to early TB diagnosis, to the lack of continuity of care and information during migration, and the availability of, and access to, health services in the new country. The recommended minimum package addresses the current shortcomings and intends to improve the situation by covering several areas: political commitment (including the implementation of a legal framework for TB cross-border collaboration), financial mechanisms and adequate health service delivery (prevention, infection control, contact management, diagnosis and treatment, and psychosocial support).

Bilingualism enriches the poor: enhanced cognitive control in low-income minority children

This study explores whether the cognitive advantage associated with bilingualism in executive functioning extends to young immigrant children challenged by poverty and, if it does, which specific processes are most affected. In the study reported here, 40 Portuguese-Luxembourgish bilingual children from low-income immigrant families in Luxembourg and 40 matched monolingual children from Portugal completed visuospatial tests of working memory, abstract reasoning, selective attention, and interference suppression. Two broad cognitive factors of executive functioning-representation (abstract reasoning and working memory) and control (selective attention and interference suppression)-emerged from principal component analysis. Whereas there were no group differences in representation, the bilinguals performed significantly better than did the monolinguals in control. These results demonstrate, first, that the bilingual advantage is neither confounded with nor limited by socioeconomic and cultural factors and, second, that separable aspects of executive functioning are differentially affected by bilingualism. The bilingual advantage lies in control but not in visuospatial representational processes.

Asymptotic behavior of cell populations described by two-type reducible age-dependent branching processes with non-homogeneous immigration()

Stem and precursor cells play a critical role in tissue development, maintenance, and repair throughout the life. Often, experimental limitations prevent direct observation of the stem cell compartment, thereby posing substantial challenges to the analysis of such cellular systems. Two-type age-dependent branching processes with immigration are proposed to model populations of progenitor cells and their differentiated progenies. Immigration of cells into the pool of progenitor cells is formulated as a non-homogeneous Poisson process. The asymptotic behavior of the process is governed by the largest of two Malthusian parameters associated with embedded Bellman-Harris processes. Asymptotic approximations to the expectations of the total cell counts are improved by Markov compensators.

Age at Immigration and the Adult Attainments of Child Migrants to the United States

Immigrants' age at arrival matters for schooling outcomes in a way that is predicted by child development theory: the chances of being a high school dropout increase significantly each year for children who arrive in a host country after the age of eight. The authors document this process for immigrants in the United States from a number of regions relative to appropriate comparison regions. Using instrumental variables, the authors find that the variation in education outcomes associated with variation in age at arrival influences adult outcomes that are important in the American mainstream, notably English-language proficiency and intermarriage. The authors conclude that children experience migration differently from adults depending on the timing of migration and show that migration during the early years of child development influences educational outcomes. The authors also find that variation in education outcomes induced by the interaction of migration and age at arrival changes the capacity of children to become fully integrated into the American mainstream as adults.

Durational and generational differences in Mexican immigrant obesity: is acculturation the explanation?

Using the Los Angeles Family and Neighborhood Survey (L.A.FANS-2; n = 1610), we explore the link between Mexican immigrant acculturation, diet, exercise and obesity. We distinguish Mexican immigrants and 2nd generation Mexicans from 3rd+ generation whites, blacks and Mexicans. First, we examine variation in social and linguistic measures by race/ethnicity, duration of residence and immigrant generation. Second, we consider the association between acculturation, diet and exercise. Third, we evaluate the degree to which acculturation, diet, exercise, and socioeconomic status explain the association between race/ethnicity, immigrant exposure to the US (duration since immigration/generation), and adult obesity. Among immigrants, we find a clear relationship between acculturation measures, exposure to the US, and obesity-related behaviors (diet and exercise). However, the acculturation measures do not clearly account for the link between adult obesity, immigrant duration and generation, and race/ethnicity.

Neighborhood inequalities in adverse pregnancy outcomes in an urban setting in Spain: a multilevel approach

The aim of the present study was to describe socioeconomic inequalities in low birth weight (LBW), premature birth (PM) and small size for gestational age at birth (SGA) between 2000 and 2005 in Barcelona, Spain, jointly evaluating the effect of mother's country of origin, and neighborhood of residence socioeconomic level measured using unemployment and educational level. We performed a cross-sectional study of births to mothers aged 12-49 years who were residents in the city of Barcelona in 2000-2005, analyzing adverse pregnancy outcomes (n = 61,676). Weighted multilevel logistic regression models were fitted with individual data on level 1 and neighborhood data on level 2, to obtain adjusted odds ratios (aOR) with 95% confidence intervals and residual variance. Individually, pregnancy outcomes are more favorable in births to older mothers and to mothers from Maghrib and Central and South America than from developed countries (including Spain) or from other developing countries. After adjusting for individual variables, poor pregnancy outcomes were associated with poor neighborhoods (more unemployment was associated to LBW: aOR = 1.56; PM aOR = 1.51; SGA aOR = 1.66). The same trend was observed for associations with illiteracy rate. The present study shows that there are socioeconomic inequalities in adverse pregnancy outcomes in the city of Barcelona. One of the main challenges in perinatal health continues to be the reduction of adverse pregnancy outcomes in the city.

Migration, Socio-cultural Factors, and Local Cultural Worlds among Fuzhounese Chinese Immigrants: Implications for Mental Health Interventions

The last two decades have seen a rapid increase of Fuzhounese immigrants (from Fujian Province, China) to the U.S. This group spurred the interest of researchers because of their new immigrant status and their demographic and sociocultural background that places them at a significant disadvantage compared with the majority of already-established Chinese immigrants. This paper synthesizes existing research on the Fuzhounese's historical/cultural and migration experiences and examines ways in which socio-cultural forces interact with post-migration stressors to impact the onset, manifestation, diagnosis, and treatment of symptoms in this group. From prior ethnographic work, we suggest that the pursuit of four core social goals plays a key role in interfering with psychiatric treatment adherence: 1) To pay off their smuggling debt (often >$80,000); 2) To send money to their natal families to improve social standing; 3) To save money for a dowry to perpetuate the familial lineage by marrying and producing offspring; and 4) To attain legal status. To offer more insight on how these core social motivations impact psychiatric disability, we present a case vignette of a Fuzhounese man diagnosed with schizophrenia. We relate his treatment issues to specific fundamental values that infuse both the lived experience of mental illness and inform clinical and community treatment strategies for this group. We also extend relevant treatment recommendations to migratory workers from other ethnic groups.

Origins of the New Latino Underclass

Over the past four decades, the Latino population of the United States was transformed from a small, ethnically segmented population of Mexicans in the southwest, Puerto Ricans in New York, and Cubans in Miami into a large national population dominated by Mexicans, Central Americans, and South Americans. This transformation occurred through mass immigration, much of it undocumented, to the point where large fractions of non-Caribbean Hispanics lack legal protections and rights in the United States. Rising illegality is critical to understanding the disadvantaged status of Latinos today. The unauthorized population began to grow after avenues for legal entry were curtailed in 1965. The consequent rise in undocumented migration enabled political and bureaucratic entrepreneurs to frame Latino migration as a grave threat to the nation, leading to a rising frequency of negative framings in the media, a growing conservative reaction, and increasingly restrictive immigration and border policies that generated more apprehensions. Rising apprehensions, in turn, further enflamed the conservative reaction to produce even harsher enforcement and more still more apprehensions, yielding a self-feeding cycle in which apprehensions kept rising even though undocumented inflows had stabilized. The consequent militarization of the border had the perverse effect of reducing rates of out-migration rather than inhibiting in-migration, leading to a sharp rise in net undocumented population and rapid growth of the undocumented population. As a result, a majority of Mexican, Central American, and South American immigrants are presently undocumented at a time when unauthorized migrants are subject to increasing sanctions from authorities and the public, yielding down-ward pressure on the status and well-being of Latinos in the United States.

Immigration and Status Exchange in Australia and the United States

This paper evaluates the status exchange hypothesis for Australia and the United States, two Anglophone nations with long immigration traditions whose admission regimes place different emphases on skills. Using log-linear methods, we demonstrate that foreign-born spouses trade educational credentials via marriage with natives in both Australian and U.S. marriage markets and, moreover, that nativity is a more salient marriage barrier for men than for women. With some exceptions, immigrant spouses in mixed nativity couples are better educated than native spouses in same nativity couples, but status exchange is more prevalent among the less-educated spouses in both countries. Support for the status exchange hypothesis is somewhat weaker in Australia partly because of lower average levels of education compared with the United States and partly because of less sharply defined educational hierarchy at the postsecondary level.

Management of immigration and pregnancy screening in northeastern Italy

This study assesses the impact of immigration in Friuli Venezia Giulia, a region of northeastern Italy, on the epidemiological features of hemoglobin patterns and on prothrombotic and trisomy risk in pregnancy for patients of non-Italian origin. This study follows a series of studies on the incidence of thalassemia and other hemoglobinopathies with reduced globin chain synthesis, that were performed during the postwar (1939–45) period in Friuli Venezia Giulia following immigration into the region from Istria and Sardinia (regions of northern and central Italy). Current data show that today’s constantly growing immigration into the region differs from previous decades, in terms of origin and quantity of migrants, who mainly come from third world countries. This has a significant impact on health care issues, and more specifically on prospective health screening for foreigners. The authors conclude that scholastic education and hospital services, either public or private, and voluntary associations, may contribute to solving the problem, but only in terms of training and organization, for non-European Union citizens arriving in northern Italy and neighboring areas, especially those from Africa, Asia, Latin America, and eastern Europe.
