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.

[The access to health services and their use by immigrant patients: the voice of the professionals]

OBJECTIVE

To find out, from the health professionals' point of view, how different immigrant groups access and use the health services.

DESIGN

Qualitative, descriptive and phenomenological study carried out in Barcelona between September and December of 2007.

SETTING

The study was carried out in the 6 Basic Health Areas of Barcelona, where there is a higher percentage of immigrant population, and in 3 public hospitals.

PARTICIPANTS

A total of 73 hospital and primary health care professionals. Theoretical sampling was carried out on respondents who defined 4 professional profiles: directors or coordinators, physicians, nurses, and cultural mediators.

METHODS

There were 7 debate groups and 12 partly-structured interviews. Both the interviews and groups were analysed by a narrative analysis of the content.

RESULTS

The outcomes indicate that, according to the professionals, the immigrant patients do not find barriers that can make their access to health services more difficult. The perception that the emergency service is their main access gate for them is unanimous, as well as that most of the immigrant patients have less continuity of care. Finally, professionals detect differences in the access and use of health services depending on their origin and the level of social integration of the immigrant group.

CONCLUSIONS

Professionals attribute a higher use of emergencies, late access to the health services, and less continuity of care, to a series of factors related to economic precariousness and to aspects related to the social inclusion. There is the room for social inclusion policies to reduce these inequalities.

Phages limit the evolution of bacterial antibiotic resistance in experimental microcosms

The evolution of multi-antibiotic resistance in bacterial pathogens, often resulting from de novo mutations, is creating a public health crisis. Phages show promise for combating antibiotic-resistant bacteria, the efficacy of which, however, may also be limited by resistance evolution. Here, we suggest that phages may be used as supplements to antibiotics in treating initially sensitive bacteria to prevent resistance evolution, as phages are unaffected by most antibiotics and there should be little cross-resistance to antibiotics and phages. In vitro experiments using the bacterium Pseudomonas fluorescens, a lytic phage, and the antibiotic kanamycin supported this prediction: an antibiotic–phage combination dramatically decreased the chance of bacterial population survival that indicates resistance evolution, compared with antibiotic treatment alone, whereas the phage alone did not affect bacterial survival. This effect of the combined treatment in preventing resistance evolution was robust to immigration of bacteria from an untreated environment, but not to immigration from environment where the bacteria had coevolved with the phage. By contrast, an isogenic hypermutable strain constructed from the wild-type P. fluorescens evolved resistance to all treatments regardless of immigration, but typically suffered very large fitness costs. These results suggest that an antibiotic–phage combination may show promise as an antimicrobial strategy.

Canaries in a coalmine: Immigration and overweight among Mexican-origin children in the US and Mexico

The prevalence of overweight is higher for Hispanic children of immigrants than children of natives. This does not fit the pattern of the epidemiological paradox, the widely supported finding that immigrants tend to be healthier than their U.S.-born peers, and it suggests that exposure to the U.S. increases immigrant children's risk of overweight. This study's primary contribution is to better assess how exposure to the U.S. environment affects childhood overweight among a homogamous ethnic group, Mexican-Americans. We do so by using an innovative binational study design to compare the weight of Mexican-American children of immigrants, Mexican-American children of natives, and Mexican children in Mexico with different propensities of having immigrant parents. Cross-sectional data are derived from a pooled sample of 9982 6-19 year old children living in either Mexico or the United States in the early 2000s. Mexican-resident children with a very high propensity to have immigrant parents have significantly lower percentile BMIs and lower odds of overweight than Mexican children with lower propensities of emigration and U.S.-resident Mexican-American children. This suggests that selection into immigration streams does not account for the high prevalence of overweight among children of Mexican immigrants. Rather, U.S. exposure significantly raises children of Mexican immigrants' risk of being overweight. Moreover, second generation children have the highest percentile BMIs and greatest odds of overweight of all comparison groups, including children of natives. This suggests that they experience risks above and beyond the effects of exposure to American society.

Increasing incidence in liver cancer in Canada, 1972-2006: Age-period-cohort analysis

BACKGROUND/AIMS

Our study aimed to assess 1) the temporal trends in incidence and mortality of liver cancer and 2) age-period-cohort effects on the incidence in Canada.

METHODS

We analyzed data obtained from the Canadian Cancer Registry Database and Canadian Vital Statistics Death Database. We first examined temporal trends by sex, age group, and birth cohort between 1972 and 2006. Three-year period rates and annual percentage change (APC) were calculated to compare the changes over the study period. We used age-period-cohort modelling to estimate underlying effects on the observed trends in incidence.

RESULTS

The overall age-adjusted incidence rates increased from 2.6 and 1.5 per 100 000 in 1972-74 to 6.5 (APC: 2.9) and 2.2 (APC: 1.2) per 100 000 in 2004-06 among males and females, respectively. The age-adjusted mortality rates increased from 3.3 and 2.0 per 100 000 in 1972-74 to 6.0 (APC: 2.3) and 2.6 (APC: 1.2) per 100 000 in 2004-06 among males and females, respectively. The incidence increased most rapidly in men aged 45-54 years (APC: 4.1) and women aged 65-74 years (APC: 1.7) over the period of study.

CONCLUSIONS

The age-period-cohort analysis suggests that birth-cohort effect is underlying the increase in incidence. While the exact reason for the increased incidence of liver cancer remains unknown, reported increase in HBV and HCV infections, and immigration from high-risk regions of the world may be important factors.

Ethnic Residential Segregation by Nativity in Great Britain and the United States*

This study examines patterns of ethnic residential integration in Great Britain and the United States. Using data from 2000/2001 censuses from these two countries, we compute segregation indexes for comparably-defined ethnic groups by nativity and for specific foreign-born groups. We find that blacks are much less segregated in Great Britain than in the U.S, and black segregation patterns by nativity tend to be consistent with spatial assimilation in the former country (the foreign born are more segregated than the native born) but not in the latter. Among Asian groups, however, segregation tends to be lower in the United States, and segregation patterns by nativity are more consistent with spatial assimilation in the U.S. but not in Great Britain. These findings suggest that intergenerational minority disadvantage persists among blacks in the U.S. and among Asians in Great Britain. We caution, however, that there are important differences in levels of segregation among specific foreign-born Asian groups, suggesting that assimilation trajectories likely differ by country of origin. Finally, the fact that segregation levels are considerably higher in the U.S. for a majority of groups, including white foreign-born groups, suggests that factors not solely related to race or physical appearance drive higher levels of ethnic residential segregation in the U.S.

A cross-national study on Mexico-US migration, substance use and substance use disorders

BACKGROUND

Epidemiologic research has consistently found lower prevalence of alcohol and drug use disorders among Hispanic immigrants to the US than among US-born Hispanics. Recent research has begun to examine how this change occurs in the process of assimilation in the US. We aimed to study immigration, US nativity, and return migration as risk factors for alcohol and drug use among people of Mexican origin in both the US and Mexico.

METHODS

Data come from nationally representative surveys in the United States (2001-2003; n=1208) and Mexico (2001-2002; n=5782). We used discrete time event history models to account for time-varying and time-invariant characteristics.

RESULTS

We found no evidence that current Mexican immigrants in the US have higher risk for alcohol or alcohol use disorders than Mexicans living in Mexico, but current immigrants were at higher risk for drug use and drug use disorders. Current Mexican immigrants were at lower risk for drug use and drug disorders than US-born Mexican-Americans. US nativity, regardless of parent nativity, is the main factor associated with increasing use of alcohol and drugs. Among families of migrants and among return migrants we found increased risk for alcohol use, drug use and alcohol and drug use disorders. Evidence of selective migration and return of immigrants with disorders was found regarding alcohol use disorders only.

CONCLUSIONS

Research efforts that combine populations from sending and receiving countries are needed. This effort will require much more complex research designs that will call for true international collaboration.

Lymphoid malignancies in U.S. Asians: incidence rate differences by birthplace and acculturation

BACKGROUND

Malignancies of the lymphoid cells, including non-Hodgkin lymphomas (NHL), HL, and multiple myeloma, occur at much lower rates in Asians than other racial/ethnic groups in the United States. It remains unclear whether these deficits are explained by genetic or environmental factors. To better understand environmental contributions, we examined incidence patterns of lymphoid malignancies among populations characterized by ethnicity, birthplace, and residential neighborhood socioeconomic status (SES) and ethnic enclave status.

METHODS

We obtained data about all Asian patients diagnosed with lymphoid malignancies between 1988 and 2004 from the California Cancer Registry and neighborhood characteristics from U.S. Census data.

RESULTS

Although incidence rates of most lymphoid malignancies were lower among Asian than white populations, only follicular lymphoma (FL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), and nodular sclerosis (NS) HL rates were statistically significantly lower among foreign-born than U.S.-born Asians with incidence rate ratios ranging from 0.34 to 0.87. Rates of CLL/SLL and NS HL were also lower among Asian women living in ethnic enclaves or lower SES neighborhoods than those living elsewhere.

CONCLUSIONS

These observations support strong roles of environmental factors in the causation of FL, CLL/SLL, and NS HL.

IMPACT

Studying specific lymphoid malignancies in U.S. Asians may provide valuable insight toward understanding their environmental causes.

Mortality trends and disparities among racial/ethnic and sex subgroups in New York City, 1990 to 2000

New York City census data for 1990 and 2000 for all-cause and disease-specific mortality adjusted by age were examined by race/ethnicity. Primary cause of death was coded as HIV/AIDS, cardiovascular disease, coronary heart disease, acute myocardial infarction, stroke, diabetes, or cancer. For White, Black, Hispanic and Asian groups, relative mortality ratios (RMR) were derived for 2000 relative to 1990. Ratios of RMR's for minority groups were derived relative to Whites. From 1990 to 2000, HIV, cancer, CVD, CHD, AMI, and stroke-related mortality decreased. Decreases in HIV-related mortality were notably less for minority males. Diabetes mortality rates rose dramatically, with Hispanic and Asian males having notably greater increases than White males. Increases in mortality among Asians exceeded those of other groups, and appear to correspond with increased immigration/acculturation. Mortality shifts among different diseases and racial groups should alert public health officials to consider immigration patterns in designing, implementing, and evaluating interventions to prevent disease-related mortality, with a goal to eliminate disparities.

Region of Birth and Disability Among Recent U.S. Immigrants: Evidence from the 2000 Census

This study aimed to test the "healthy immigrant" hypothesis and assess health heterogeneity among newly arrived working-age immigrants (18-64 years) from various regions of origin. Using the 5% sample of the 2000 U.S. Census (PUMS), we found that, compared with their native-born counterparts, immigrants from all regions of the world were less likely to report mental disability and physical disability. Immigrants from selected regions of origin were, however, more likely to report work disability. Significant heterogeneity in disabilities exists among immigrants: Those from Eastern Europe and Southeast Asia reported the highest risk of mental and physical disability, and those from East Asia reported the lowest risk of physical disability. Furthermore, Mexican immigrants reported the lowest risk of mental disability, and Canadian immigrants reported the lowest risk of work disability. Socioeconomic status and English proficiency partially explained these differences. The health advantage of immigrants decreased with longer U.S. residence.

Celiac disease and immigration in Northeastern Italy: the "drawn double nostalgia" of "cozonac" and "panettone" slices

Many investigators consider children’s drawings to be an important test in the evaluation of stress and anxiety, but few studies have examined the reliability and validity of indicators of emotional distress in children’s projective drawings. In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the “drawn double nostalgia” of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are “cozonac” (from the native country) and “panettone” (Italian cake flavor) represents a problem that will be difficult to resolve. Only some children’s hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem.

NEIGHBORHOOD IMMIGRATION AND NATIVE OUT-MIGRATION

This study combines data from the Panel Study of Income Dynamics with data from four censuses to examine the effects of foreign-born populations in the immediate neighborhood of residence and surrounding neighborhoods on the residential mobility decisions of native-born black and white householders. We find that the likelihood of out-mobility for native householders is significantly and positively associated with the relative size of, and increases in, the immigrant population in the neighborhood. Consistent with theoretical arguments related to the distance dependence of mobility, large concentrations of immigrants in surrounding areas reduce native out-mobility, presumably by reducing the attractiveness of the most likely mobility destinations. A sizable share of local immigration effects can be explained by the mobility-related characteristics of native-born individuals living in immigrant-populated areas, but the racial composition of the neighborhood (for native whites) and local housing market conditions (for native blacks) also are important mediating factors. The implications of these patterns for processes of neighborhood change and broader patterns of residential segregation are discussed.

Disability among native-born and foreign-born blacks in the United States

Using the 5% Public Use Micro Data Sample (PUMS) from the 2000 U.S. census, we examine differences in disability among eight black subgroups distinguished by place of birth and Hispanic ethnicity. We found that all foreign-born subgroups reported lower levels of physical activity limitations and personal care limitations than native-born blacks. Immigrants from Africa reported lowest levels of disability, followed by non-Hispanic immigrants from the Caribbean. Sociodemographic characteristics and timing of immigration explained the differences between these two groups. The foreign-born health advantage was most evident among the least-educated except among immigrants from Europe/Canada, who also reported the highest levels of disability among the foreign-born. Hispanic identification was associated with poorer health among both native-born and foreign-born blacks.
