Are immigrant enclaves healthy places to live? The Multi-ethnic Study of Atherosclerosis

The growing size and changing composition of the foreign-born population in the USA highlights the importance of examining the health consequences of living in neighborhoods with higher proportions of immigrants. Using data from the Multi-ethnic Study of Atherosclerosis in four US cities, we examined whether neighborhood immigrant composition was associated with health behaviors (diet, physical activity) among Hispanic and Chinese Americans (n = 1902). Secondarily we tested whether neighborhoods with high proportions of immigrants exhibited better or worse neighborhood quality, and whether these dimensions of neighborhood quality were associated with healthy behaviors. Neighborhood immigrant composition was defined based on the Census 2000 tract percent of foreign-born from Latin-America, and separately, percent foreign-born from China. After adjustment for age, gender, income, education, neighborhood poverty, and acculturation, living in a tract with a higher proportion of immigrants was associated with lower consumption of high-fat foods among Hispanics and Chinese, but with being less physically active among Hispanics. Residents in neighborhoods with higher proportions of immigrants reported better healthy food availability, but also worse walkability, fewer recreational exercise resources, worse safety, lower social cohesion, and lower neighborhood-based civic engagement. Associations of neighborhood immigrant composition with diet persisted after adjustment for reported neighborhood characteristics, and associations with physical activity were attenuated. Respondent-reported neighborhood healthy food availability, walkability, availability of exercise facilities and civic participation remained associated with behaviors after adjusting for immigrant composition and other covariates. Results show that living in an immigrant enclave is not monolithically beneficial and may have different associations with different health behaviors.     

Acculturation Versus Cultural Retention: The Interactive Impact of Acculturation and Co-ethnic Ties on Substance Use Among Chinese Students in the United States

Acculturation is often found to increase substance use among immigrants in the U.S., but such effect may depend on how immigrants are attached to their co-ethnic community. Meanwhile, the high socioeconomic status of some new immigrant groups also challenges the classical assumption that ties to co-ethnic community are associated with deviance. With a sample (n?=?960) collected from a population of Chinese students in a large public university in the U.S., we tested how do the interplays between acculturation and co-ethnic ties affect substance use. This study establishes that: (1) different dimensions of acculturation have opposite effects on substance use; (2) acculturative stress does not explain the association between acculturation and substance use; (3) acculturation increases the likelihood of substance use only when one has weak attachment to their co-ethnic community. The findings are consistent for three dependent variables: smoking, drinking, and drunkenness, and for the different constructs of acculturation and co-ethnic ties. Ties to co-ethnic community may provide important social support for immigrants, while acculturation may alleviate the insular subculture that promotes at-risk behaviors. We encourage policy makers to consider the cooperative nature of acculturation and cultural retention for the improvement of health among this growing population.     

Measures of Acculturation are Associated with Cardiovascular Disease Risk Factors, Dietary Intakes, and Physical Activity in Older Chinese Americans in New York City

Cardiovascular disease (CVD) is the leading cause of death in the U.S. and affects Chinese Americans disproportionately compared to other ethnic groups in the American population. Studies of immigrant populations have shown that risk factors for CVD, including diet and physical activity, differ by acculturation. This cross-sectional study evaluated whether two measures of acculturation (region of birthplace, length of residence in the U.S.) were associated with CVD risk factors, dietary intakes, and physical activity of 125 older Chinese Americans who participated in health fairs conducted in NYC. In this study, mean waist circumference differed significantly by birthplace. Mean systolic and diastolic blood pressure differed significantly by length of residence in the U.S. Mean intake of vitamin B6, folate and calcium differed significantly by birthplace: Chinese Americans from Hong Kong had the highest mean vitamin B6 intake whereas older Chinese Americans from Northern China had the highest folate and calcium intakes. Mean intake of riboflavin differed significantly by length of residence in the U.S. with Chinese Americans adults who lived in the U.S. less than 10 years having the highest mean intake. Mean dairy intake of Chinese Americans differed significantly by birthplace, with adults from northern China having the highest mean dairy intake. Vigorous-intensity physical activity differed significantly by birthplace, with adults from Hong Kong reporting the most daily minutes of vigorous-intensity physical activity. This study suggests that acculturation may be associated with the cardiovascular health of older Chinese Americans living in NYC.     

Differences in self-rated health by immigrant status and language preference among Arab Americans in the Detroit Metropolitan Area

Arab Americans are a growing minority in the U.S., yet only a few studies have examined their health utilizing representative samples. Using data from the 2003 Detroit Arab American Study, which is based on a probability sample, we examined the self-rated health (SRH) of Arab Americans by two measures of acculturation – immigrant status and language preference. We specified logistic regression models to test whether immigrants report better or poorer health status compared to U.S.-born Arab Americans and whether language preference among the immigrant generation accounts for the association between immigrant status and SRH. Our findings reveal that the health status of Arab Americans improves with acculturation. Arab immigrants are more likely to report poorer SRH compared to U.S.-born Arab Americans. When language preference is taken into account, Arabic-speaking immigrants are more likely to report poorer SRH compared to both U.S.-born Arab Americans and to English-speaking immigrants. We discuss these findings in light of similar ones obtained in the literature on SRH among other immigrant groups in the U.S. We conclude by arguing that language is an important measure to include in SRH studies among Arab Americans as well as other non-English speaking ethnic groups.     

"So We Adapt Step by Step": Acculturation experiences affecting diabetes management and perceived health for Chinese American immigrants

This study examines how acculturation affects type 2 diabetes management and perceived health for Chinese American immigrants in the U.S. Acculturation experiences or cultural adaptation experiences affecting diabetes management and health were solicited from an informant group of immigrant patients and their spouses (N = 40) during group, couple and individual interviews conducted from 2005 to 2008. A separate respondent group of immigrant patients and their spouses (N = 19) meeting inclusion criteria reviewed and confirmed themes generated by the informant group. Using interpretive phenomenology, three key themes in patients’ and spouses’ acculturation experiences were identified: a) utilizing health care, b) maintaining family relations and roles, and c) establishing community ties and groundedness in the U.S. Acculturation experiences reflecting these themes were broad in scope and not fully captured by current self-report and proxy acculturation measures. In the current study, shifting family roles and evaluations of diabetes care and physical environment in the U.S. significantly affected diabetes management and health, yet are overlooked in acculturation and health investigations. Furthermore, the salience and impact of specific acculturation experiences respective to diabetes management and perceived health varied across participants due to individual, family, developmental, and environmental factors. In regards to salience, maintaining filial and interdependent family relations in the U.S. was of particular concern for older participants and coping with inadequate health insurance in the U.S. was especially distressing for self-described lower-middle to middle-class participants. In terms of impact, family separation and relocating to ethnically similar neighborhoods in the U.S. differentially affected diabetes management and health due to participants’ varied family relations and pre-migration family support levels and diverse cultural and linguistic backgrounds, respectively. Implications for expanding current conceptualizations and measures of acculturation to better comprehend its dynamic and multidimensional properties and complex effects on health are discussed. Additionally, implications for developing culturally-appropriate diabetes management recommendations for Chinese immigrants and their families are outlined.     

Does being an immigrant make a difference in seeking physician services?

The current study investigated the effects of immigration status, acculturation, and health beliefs on the use of preventive and non-preventive visits, through use of a nationally representative sample of U.S.-born and foreign-born adults. U.S.-born adults were found to have significantly more preventive and non-preventive visits than immigrants. The effects on predicting preventive visits of education, having a usual source of care, and having other public insurance were stronger among immigrants than among the U.S.-born. Health confidence and believing in the need for health insurance significantly predicted the numbers of both preventive and non-preventive visits among the U.S.-born but correlated little with either type of visit among immigrants. Among immigrant adults, acculturation affected only the number of preventive visits. The lower utilization of both preventive and non-preventive care among immigrants may be associated with a combination of better health and more limited enabling resources.     

Physical and mental health characteristics of U.S.- and foreign-born adults: United States, 1998-2003

OBJECTIVE: This report presents national prevalence estimates of selected measures of physical health status and limitations, health care access and utilization, and mental health status among the civilian noninstitutionalized population of U.S.- and foreign-born adults aged 18 years and over in four race-ethnicity groups in the United States. METHODS: The estimates in this report were derived from the Family Core and Sample Adult components of the 1998-2003 National Health Interview Surveys, conducted annually by the Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS). Estimates were generated and comparisons conducted using the SUDAAN statistical package to account for the complex survey sample design. Data were age adjusted to the 2000 U.S. standard population. RESULTS: In general, the foreign-born population was younger, less likely to have a high school diploma, more likely to be poor, heavily concentrated in the central cities of metropolitan areas, and more likely to live in large families, compared with their U.S.-born counterparts. Hispanic immigrants were the least likely to have health insurance or to have a usual source of health care compared with other immigrant groups. Non-Hispanic black and Hispanic adults, regardless of nativity, were more likely to be obese than non-Hispanic white and non-Hispanic Asian adults. However, non-Hispanic black and Hispanic immigrant adults were significantly less likely to be obese than their U.S.-born counterparts. Hispanic immigrants were more likely to be obese the longer they lived in the United States. Foreign-born nonHispanic black and Hispanic immigrant adults experienced fewer symptoms of serious psychological distress compared with their U.S.-born counterparts. CONCLUSIONS: There are significant differences in physical health status and mental health status among U.S.-born and foreign-born adults. Foreign-born adults enjoy considerable advantages over their U.S.-born counterparts for many health measures despite limited access to health care and unfavorable sociodemographic characteristics. Differences in the impact of length of stay in the United States on immigrant health suggest that the role of acculturation in understanding immigrant health is complex and may differ for various race/ethnicity groups.     

Negative Acculturation in Sleep Duration Among Mexican Immigrants and Mexican Americans

Negative acculturation, the increase in high-risk profiles as immigrants live longer in the U.S., is found for a range of health behaviors and outcomes among Latino populations. Yet it has never been explored with regard to sleep duration. Using the National Health Interview Survey, we investigate Mexican immigrant and U.S.-born Mexican-American sleep durations. U.S.-born Mexican Americans are around 40% (P < 0.05) more likely to be short sleepers than Mexican immigrants after adjusting for demographic characteristics. These relationships are attenuated with the addition of health behavior variables (OR = 1.25, n.s.). This is explained because U.S.-born Mexican Americans have higher rates of smoking and stress levels, both of which are associated with increased risks of short sleeping. Because chronic partial sleep deprivation may increase health risks directly and indirectly through impaired judgment, sleep may be a mechanism through which health disparities between Mexican immigrants and U.S.-born Mexican Americans emerge.     

Self-Assessments of Health by Korean Immigrant Women

The purpose of this study was twofold: to discover how Korean immigrant women perceived their health and to identify associations between social indicators and the health of Korean immigrant women. Participants in the study comprised a nonprobability sample of 137 Korean immigrant women living in the United States who submitted questionnaires about their health to the researcher by U.S. mail in 2004. Approximately 49% of the participants perceived their health as fair or poor. After age, income, education, marital status, and occupational status were controlled, the significant predictors of self-assessed health were involvement in exercise and length of residency in the United States. In future studies, the relationships between perception of health related to acculturation and self-rating health should be investigated.

Use of home care services by elderly Chinese immigrants

Using the Anderson Service model, this study examined the level and predictors of using selected home care services by elderly Chinese immigrants in Canada. Data from 1,537 randomly selected Chinese immigrants aged 65 years and older were used. Only 5.2% of participants reported using home care services. Being older, living alone, having a post-secondary education, immigrating from Hong Kong or Southeast Asia, having a higher level of agreement with Chinese health beliefs, higher social support, and poorer physical and mental health were predictors for home care service use among elderly Chinese. The probability of using homecare services lessens with increased self-rated financial adequacy. These findings point to the need for service providers to address the gap in use of home care between elderly Chinese immigrants and overall elderly Canadians through promoting appropriate use of home care among elderly Chinese immigrants.     

Insurance Status and Health Service Utilization Among Newly-Arrived Older Immigrants

Following the 1996 welfare reform, newly arrived older immigrants with less than 5 years of residence (NOIs) have been barred from Medicaid benefits. Neither are they eligible for Medicare due to lack of work history. This study examines the relationship between immigrant status (NOIs or not), health insurance, and health service use among older immigrants; whether insurance mediates the relationship between immigrant status and health service use. The 2000 National Health Interview Survey was analyzed. The sample includes respondents aged 65 or older who are foreign-born (N=1, 178). The adapted Andersen model was used. A series of logistic regressions show insurance is a complete mediator between immigrant status and health service use among older immigrants. Immigrant status was significantly related to the mediator, health insurance; older immigrants with longer than 5 years of residence were 31 times more likely than NOIs to have health insurance in terms of odds. Also, different from health service use among U.S.-born older adults, older immigrants’ service use is significantly related to their insurance status. There was no direct relationship between immigrant status and health service use.     

Does Acculturation Influence Physical Activity in Japanese American Older Adults?

PURPOSE: Despite the health benefits of physical activity, demographic and health factors as well as cultural backgrounds are thought to influence participation in physical activity. The aim of this study is to examine whether acculturation is associated with physical activity in a sample of Japanese American older adults living on the continental United States. METHODS: A survey was mailed to Japanese Americans identified from the mailing list of two community­based organizations. The survey included questions on physical activity, acculturation, demographics, health behaviors, and self­reported health status. Data were analyzed using bivariate and multiple regression techniques. FINDINGS: Acculturation was not a significant predictor of phsical activity in either community sample, or the pooled sample, after conrolling for other sociodemographic andhealth status variables. The models explained 23% to 2% of the variance in physical activity. Statistically significant predictors of physical activity included gender, work status, age, income, and health status. CONCLUSIONS: Our findings differ from studies of Japanese Americans in Hawaii and other racial/ethnic groups, suggesting that accultraion may have differential effects depending on the environment and the racial/ethnic group under study. KEY WORDS: Japanese American, physical activity, acculturation     

Immigrant status and acculturation influence substance use among New Zealand youth

Objective: To investigate the associations between generational status, acculturation and substance use among immigrant and non‐immigrant secondary school students in New Zealand. Methods: A nationally representative sample of secondary school students in New Zealand was selected using a two‐stage cluster sample design. Of the 8,999 students in the sample, 23.81% were first‐generation immigrants and 20.90% were second‐generation immigrants; the remaining 55.29% students are collectively referred to as ‘non‐immigrant’ peers. Logistic regression models adjusted the associations of interest for age, gender, ethnicity, socioeconomic status and experience of ethnic discrimination. Results: First and second‐generation immigrants showed significantly lower risks of smoking cigarettes compared with their non‐immigrant peers. Similar trends were apparent for consuming alcohol and marijuana weekly. The inclusion of some characteristics suggestive of acculturation in multivariable models did not influence the relationship between generational status and smoking cigarettes, but attenuated the apparent protective effect of being a first‐generation immigrant with regard to alcohol and marijuana use. Conclusions and implications: The study shows the lower likelihood of substance use among newer immigrants in a nationally representative sample of New Zealand youth. Policies and health programs that build on this positive profile and reduce the risk of adverse changes over time require attention.     

Health Behaviors,Chronic Disease Prevalence and Self-Rated Health of Older Asian Indian Immigrants in the U.S.

The purpose of this study was to examine the correlates of healthy behaviors and self-rated health in middle-aged and older Asian Indian immigrants in the U.S. Asian Indian men (n = 162) and women (n = 64), 50 years of age or older completed a telephone survey which collected information regarding demographics, behavioral risk factors, acculturation, perceived control, quality of social support, depression, body mass index, chronic disease prevalence, and self-rated health. Participants’ average length of residence in the U.S. was 25 years, 52% were normal weight, 41% were vegetarians, 55% incorporated aerobic activity into daily lifestyle, and only 5% smoked. Hypertension and diabetes were most common chronic diseases (31 and 18%, respectively). Younger age, longer length of residence and a bicultural or more American ethnic identity were associated with greater participation in physical activity. Likewise, higher income, a bicultural or more American ethnic identity and depression were associated with higher fat intake. Poor self-rated health was associated with older age, female gender, BMI > 25, satisfaction with social support, and greater number of chronic disease conditions. A multitude of factors influence the practice of healthy behaviors and the perceived health of Asian Indian immigrants, which should be addressed when developing culturally appropriate health promotion interventions.     

The Immigrant Experience and Alcohol Use: Heart Rate as a Source of Risk and Resilience

The immigration experience in the USA has been linked to a wide range of behavioral and physical outcomes. Studies report that immigrants, relative to native-born citizens, are less likely to develop alcohol use habits despite facing hardship during the acculturation process. Limited research, however, has examined whether and to what extent resting heart rate (RHR) plays a role in accounting for individual differences in the acculturation process in the USA. To begin to address this gap in research, cross-sectional self-report data (N?=?4775) from a nationally representative sample of US adults are analyzed to examine the association between the immigrant experience, alcohol use, and drunkenness. The role of low, mean, and high RHR on this association is investigated. The results reveal that respondents with higher levels of the immigrant experience report lower levels of alcohol use and drunkenness. RHR partially conditions the relationship between the immigrant experience and alcohol use, whereby respondents with higher levels of the immigrant experience and high RHR report less alcohol use and drunkenness, compared to more native respondents with low RHR. Immigrant experience and alcohol use were associated, but not with drunkenness among respondents with average RHR levels, relative to those with low RHR levels. The results suggest that RHR may be a potential source of both risk for and resilience to the development of alcohol use behaviors among immigrants going through the acculturation process in the USA.

     

Understanding Health,Violence, and Acculturation Among South Asian Women in the US

The devastating effects of experiencing violence in childhood are seen well into adulthood. This has been particularly difficult to assess among South Asians living in the U.S., due to a lack of disaggregated data on this ethnic group. In a web-based survey administered to a convenience sample of South Asian women living in the U.S. (n?=?535), information was gathered on experience/exposure to childhood violence; adult intimate partner violence; and adverse health outcomes, including ever suicide ideation/attempt, experiences of quality of life and body esteem in adulthood. Further, an individual’s acculturation levels were measured specifically looking at cultural identity which was guided by Berry’s biculturalism model. This study found that acculturation status is a key factor with respect to childhood verbal, physical, and sexual abuse, as well as body esteem and an individual’s well-being. These results suggest that acculturation plays a key role for childhood violence, as well as key adult health indicators. The findings in this study, suggest that more research is warranted to better understand the complex relationships between acculturation status and health. While studies of South Asian immigrants have increased substantially, the study on how acculturation influences family violence and health outcomes has lagged behind. The findings in this study will provide guidance for future work in understanding how acculturation can play a key role in addressing the health and well-being of South Asian women in the U.S.     

“My health has improved because I always have everything I need here…”: A qualitative exploration of health improvement and decline among immigrants

Immigrants in Canada constitute approximately 20% of the total population and will continue to account for a significant portion of the country's population in the future. Accordingly, a growing body of research has focused on examining the disparity in health status between the increasing foreign-born and the Canadian-born populations. The healthy immigrant effect, in particular, acknowledges that immigrants have better health status than their Canadian-born counterparts upon arrival in the country. However, studies have shown that over time the health of immigrants declines to a level on par with the Canadian-born population. There is much speculation as to the reasons for this decline including acculturation (i.e., uptake of unhealthy lifestyles) and a lack of access to health care. Yet, there have been few studies to examine possible reasons for potential declines in health, especially from the perspective of immigrants themselves. This study is one of the first to qualitatively examine perceived changes in health status and reasons for health status change among immigrants. The paper presents the results of 23 in-depth interviews with adults with recent (less than 3 years of residency), mid-term (3–10 years), and long-term (more than 10 years) immigrants living in the Greater Toronto Area. The results reveal that the majority of the participants believed their health had remained stable or even improved over time due to improved living standards and lifestyle behaviours in Canada. Those who perceived their health to have worsened over time attributed the change to the stress associated with migration, and the aging process rather than the adoption of an unhealthy lifestyle. Additionally, while the vast majority of participants reported improved access to resources upon migration, there were mixed reviews in terms of how beneficial these resources were or could be for health. The findings highlight the need for research to incorporate mental health into studies on changing immigrant health status and to focus on those factors contributing to high levels of stress among more recent immigrants.     

Neighborhood context and acculturation among Central American immigrants

Years in the US is often used as a proxy for acculturation, and level of acculturation may be an important predictor of differential health outcomes for immigrants. Some studies have examined the interaction between community level factors and acculturation, but not among Latinos. Level of acculturation and neighborhood concentration of Latinos was assessed in a sample of 194 Spanish-speaking, immigrant, pregnant Latinas. Neighborhood concentration of Latinos moderated the association between years living in the US and acculturation level. For individuals living in a high concentration of Latinos, longer time in the US was less related to higher levels of acculturation. In contrast, among Latinas living in a low concentration of other Latinos, the amount of time since immigrating to the US was strongly associated with level of acculturation. These findings have implications for health outcomes research done with immigrant groups, particularly Latinos.
