Nativity and Cigarette Smoking among Lower Income Blacks: Results from the Healthy Directions Study

Blacks in the United States bear the greatest disease burden associated with cigarette smoking. Previous studies have shown that the rapidly increasing population of foreign-born Blacks has lower smoking rates compared to their native-born counterparts. However, less is known about whether cigarette smoking among Blacks varies by region of birth (US, Africa, or the Caribbean), generational status, or acculturation. We examined the association between nativity and cigarette smoking among 667 Black adult men and women enrolled in the Harvard Cancer Prevention Program project. In multi-variable analyses, US-born Blacks were more likely to be smokers compared to those born in the Caribbean (OR = 0.16, 95% CI 0.08, and 0.34) or in Africa (OR = 0.24, 95% CI 0.08, and 0.74). Language acculturation was positively associated with cigarette smoking (OR = 2.62, 95% CI 1.17, and 5.85). We found that US-born Blacks were more likely to be current cigarette smokers than those born in either Caribbean or African countries. Our findings highlight the importance of intervening early new Black immigrants to stem the uptake of cigarette smoking behaviors as individuals become acculturated.     

Perinatal HIV Prevention Outcomes in U.S.-Born Versus Foreign-Born Blacks,PSD Cohort, 1995–2004

We examined differences in HIV-infected U.S.-born and foreign-born black mothers who delivered perinatally HIV-exposed and -infected children during 1995–2004 in the Pediatric Spectrum of HIV Disease Project, a longitudinal cohort study. Prevalence ratios were calculated to explain differences in perinatal HIV prevention opportunities comparing U.S.-born to foreign-born and African-born to Caribbean-born black mothers. U.S.-born compared with foreign-born HIV-infected black mothers were significantly more likely to have used cocaine or other non-intravenous illicit drugs, exchanged money or drugs for sex, known their HIV status before giving birth, received intrapartum antiretroviral (ARV) prophylaxis, and delivered a premature infant; and were significantly less likely to have received prenatal care or delivered an HIV-infected infant. African-born compared with Caribbean-born black mothers were more likely to receive intrapartum ARV prophylaxis. These differences by maternal geographical origin have important implications for perinatal HIV transmission prevention, and highlight the validity of disaggregating data by racial/ethnic subgroups.     

US Black vs White disparities in foetal growth: physiological or pathological?

BACKGROUND: Birthweight for gestational age is lower in US Black infants than in US White infants. It is unknown, however, whether this difference is 'normal' (i.e. physiological) or reflects pathological foetal growth restriction. METHODS: We applied an analytic approach based on foetuses at risk to compare gestational age-specific rates of live birth, 'revealed' small-for-gestational-age (SGA), and neonatal mortality among singleton infants >or=22 weeks of gestation and >or=500 g born in 1998-2000 to US White (n = 9 012 194), US-born Black (n = 1 554 382), and foreign-born Black (n = 200 395) mothers. Graphical methods and Cox proportional hazards regression analyses were used to compare outcomes in the three ethnic groups. RESULTS: Rates of live birth and neonatal mortality were highest at all gestational ages in US-born Blacks, lowest in Whites, and intermediate in foreign-born Blacks. The revealed SGA pattern cohered much more closely with the observed pattern for neonatal mortality when SGA was defined based on a single, overall standard of birthweight for gestational age than when based on ethnic group-specific standards. CONCLUSION: The closer coherence of revealed SGA and neonatal mortality rates based on a single standard and the intermediate pattern among foreign-born Blacks strongly suggest that Black-White differences in birthweight for gestational age are pathological, rather than physiological.     

Health status, health insurance, and health care utilization patterns of immigrant Black men

OBJECTIVES: This study sought to describe the health status, health insurance, and health care utilization patterns of the growing population of immigrant Black men. METHODS: We used data from the 1997-2000 National Health Interview Survey to examine and then compare health variables of foreign-born Black men with those of US-born Black and White men. Logistic regression analyses were used to examine health outcomes. RESULTS: Foreign-born Black men were in better overall health than their US-born Black counterparts and were much less likely than either US-born Black or White men to report adverse health behaviors. Despite these health advantages, foreign-born Black men were more likely than either US-born Black or White men to be uninsured. CONCLUSIONS: In the long term, immigrant Black men who are in poor health may be adversely affected by lack of health care coverage.     

Variation in Birth Outcomes by Mother’s Country of Birth Among Non-Hispanic Black Women in the United States

Rates of prematurity (PTB) and small-for-gestational age (SGA) were compared between US-born and foreign-born non-Hispanic black women. Comparisons were also made between Sub-Saharan African-born and Caribbean-born black women and by maternal country of birth within the two regions. Comparisons were adjusted for sociodemographic, health behavioral and medical risk factors available on the birth record. Birth record data (2008) from all states (n = 27) where mother’s country of birth was recorded were used. These data comprised 58 % of all singleton births to non-Hispanic black women in that year. Pearson Chi square and logistic regression were used to investigate variation in the rates of PTB and SGA by maternal nativity. Foreign-born non-Hispanic black women had significantly lower rates of PTB (OR 0.727; CI 0. 726, 0.727) and SGA (OR 0.742; CI 0.739–0.745) compared to US-born non-Hispanic black women in a fully adjusted model. Sub-Saharan African-born black women compared to Caribbean-born black women had significantly lower rates of PTB and SGA. Within each region, the rates of PTB and SGA varied by mother’s country of birth. These differences could not be explained by adjustment for known risk factors obtained from vital records. Considerable heterogeneity in rates of PTB and SGA among non-Hispanic black women in the US by maternal nativity was documented and remained unexplained after adjustment for known risk factors.     

Variations in Health and Health Behaviors by Nativity Among Pregnant Black Women in Philadelphia

Objectives. We compared health behaviors and health outcomes among US-born, African-born, and Caribbean-born pregnant Black women and examined whether sociodemographic and psychosocial characteristics explained differences among these population subgroups.Methods. We analyzed data from a prospective cohort study conducted in Philadelphia, Pennsylvania, with a series of nested logistic regression models predicting tobacco, alcohol, and marijuana use and measures of physical and mental health.Results. Foreign-born Black women were significantly less likely to engage in substance use and had better self-rated physical and mental health than did native-born Black women. These findings were largely unchanged by adjustment for sociodemographic and psychosocial characteristics. The foreign-born advantage varied by place of birth: it was somewhat stronger for African-born women than for Caribbean-born women.Conclusions. Further studies are needed to gain a better understanding of the role of immigrant selectivity and other characteristics that contribute to more favorable health behaviors and health outcomes among foreign-born Blacks than among native-born Blacks in the United States.Studies examining health differences among immigrant subgroups and their native-born counterparts have largely focused on Hispanics. This literature consistently shows that Hispanics born outside the United States have lower mortality rates and better health and reproductive outcomes than do US-born Hispanics.^1–3 These studies also reveal that the protective effect of foreign-born status varies by country of origin.^4,5 For example, Cho et al. found that Mexican immigrants had better self-reported health status, fewer activity limitations, and fewer sick days confined to bed than did persons from Cuba and Central America,⁴ and Hummer et al. reported a similar variation for infant mortality rates.³Far less is known about the health of foreign-born Black immigrants, who make up an expanding proportion of US immigrants. For example, in 1960 fewer than 1% of Black US residents were foreign born; by 2005 this figure increased to 8%.^6,7 Studying health differentials among native-born and foreign-born Blacks may shed light on factors that contribute to racial health disparities in the United States.Previous studies showed that health behaviors, health status, and reproductive outcomes were more favorable among foreign-born Blacks than among native-born Blacks.^3,8–10 However, only a handful of studies have examined health status¹¹ or birth outcomes^12–15 among foreign-born Blacks by region of birth. These studies found that foreign-born Black women, whether from the Caribbean¹⁴ or Africa,¹² were less likely than US-born Black women to have low-birth-weight infants. A recent study of 2000 vital records for New York, New York, observed that although the risk of low birth weight was lower among infants of foreign-born Black mothers than among infants of native-born Black mothers, that risk varied by the foreign-born mothers'' place of birth: infants born to women from the Dominican Republic had the lowest risk, and infants born to women from Haiti had the highest risk.¹⁵ Proposed explanations for more favorable birth outcomes and better health status among the foreign-born include selective migration, greater social support, and fewer adverse health behaviors.^{4,5,9,13,14,16–18}We examined the role of nativity in health behaviors and health status among pregnant Black women in Philadelphia, Pennsylvania. We compared health behaviors and status among Black women born in the United States, the Caribbean, and Africa. Our data, collected through extensive face-to-face interviews, allowed us to examine whether individual-level sociodemographic and psychosocial characteristics explained differences in behavior and health among Black women by region of birth.     

HIV/AIDS Surveillance Data for New York City West Indian–Born Blacks: Comparisons With Other Immigrant and US-Born Groups

Objectives. Although the risk of HIV among New York City West Indian–born Black immigrants often is assumed to be high, population-based data are lacking, a gap we aimed to address.Methods. Using 2006–2007 HIV/AIDS surveillance data from the New York City Department of Health and Mental Hygiene and population data from the US Census American Community Survey 2007, we compared the rate of newly reported HIV diagnoses, prevalence of people living with HIV/AIDS, and distribution of transmission risk categories in West Indian–born Blacks, 2 other immigrant groups, and US-born Blacks and Whites.Results. The age-adjusted rate of newly reported HIV diagnoses for West Indian–born Blacks was 43.19 per 100 000 (95% confidence interval [CI] = 38.92, 49.10). This was higher than the rate among US-born Whites (19.96; 95% CI = 18.63, 21.37) and Dominican immigrants and lower than that among US-born Blacks (109.48; 95% CI = 105.02, 114.10) and Haitian immigrants. Heterosexual transmission was the largest risk category in West Indian–born Blacks, accounting for 41% of new diagnoses.Conclusions. Although much lower than in US-born Blacks, the rate of newly reported HIV diagnoses in West Indian–born Blacks exceeds that among US-born Whites. Additional work is needed to understand the migration-related sources of risk.Immigrants from English-speaking Caribbean basin countries, often referred to as the West Indians, have been migrating to the United States for many decades, and they and their descendants constitute a large and culturally significant population in major Eastern seaboard cities, including New York City (NYC). The majority (81%) identify as Black, with a significant minority identifying as East Indian.1 Considering only those who are first-generation immigrants, the latest estimates (2007–2008) show that West Indians represent 21% of foreign-born persons in NYC and almost 25% of the NYC Black population.2 Despite the size of this immigrant group, in HIV/AIDS surveillance reports they have not been disaggregated from all Blacks nor from the Caribbean-born population overall, although some data suggest their HIV risk may be high.3     

Pregnancy risk factors and birth outcomes in Washington State: a comparison of Ethiopian-born and US-born women.

This study compared birth outcomes of three cohorts of women with singleton live births in Washington State between 1980 and 1991: all Black Ethiopian-born women (n = 264) and samples of US-born Black (n = 526) and White (n = 546) women. Ethiopians were older, more likely to be married, and less likely to smoke than were US-born women, and they were less likely to have anemia than US-born Blacks. The adjusted low-birthweight risk among Ethiopians was similar to that of US-born Blacks (relative risk [RR] = 0.9) and Whites (RR = 1.1). Ethiopians were more likely to have high-birthweight infants than were US-born Blacks (RR = 4.0). Cultural and behavioral etiologies may explain these favorable birth outcomes.     

Ethnicity, nativity, and the health of American Blacks

There have been few empirical studies of ethnic differences in health within the American Black population. Logistic regressions were used to examine the relationships among ethnicity, nativity, depressive symptoms, and physical health in the two largest ethnic groups of American Blacks, African Americans and Caribbean Blacks. The data were from the National Survey of American Life, a national household survey representative of the non-institutionalized U.S. Black population. We found that African Americans, U.S.-born Caribbean Blacks, and Caribbean-born Blacks had significantly different self-ratings of their health and self-reports of being diagnosed with a chronic physical health condition: Caribbean-born Blacks had the best health outcomes and U.S.-born Caribbean Blacks had the worst. This finding remained significant even after considering self-reported depressive symptoms. This study highlights the importance of considering ethnic diversity, nativity and immigration as independent sources of variation in health status within the American Black population.     

Differences in the self-reported racism experiences of US-born and foreign-born Black pregnant women

Differential exposure to minority status stressors may help explain differences in United States (US)-born and foreign-born Black women's birth outcomes. We explored self-reports of racism recorded in a survey of 185 US-born and 114 foreign-born Black pregnant women enrolled in Project Viva, a prospective cohort study of pregnant women in Boston, Massachusetts, USA. Self-reported prevalence of personal racism and group racism was significantly higher among US-born than foreign-born Black pregnant women, with US-born women having 4.1 and 7.8 times the odds, respectively, of childhood exposure. In multivariate analyses, US-born women's personal and group racism exposure also was more pervasive across the eight life domains we queried. Examined by immigrant subgroups, US-born women were more similar in their self-reports of racism to foreign-born women who moved to the US before age 18 than to women who immigrated after age 18. Moreover, US-born women more closely resembled foreign-born women from the Caribbean than those from Africa. Differential exposure to self-reported racism over the life course may be a critically important factor that distinguishes US-born Black women from their foreign-born counterparts.     

Enigma of maternal race and infant birth weight: a population-based study of US-born Black and Caribbean-born Black women

The authors used 1985-1990 Illinois' vital records to determine the low birth weight components of infants delivered to US-born Black women, Caribbean-born Black women, and US-born White women. The moderately low birth weight rate (1,500-2,499 g) was 10% for infants with US-born Black mothers (n = 67,357) and 6% for infants with Caribbean-born mothers (n = 2,265) compared with 4% for infants with US-born White mothers (n = 34,124); the relative risk equaled 2.7 (95% confidence interval (CI): 2.5, 2.8) and 1.7 (95% CI: 1.4, 2.0), respectively. The very low birth weight rate (<1,500 g) was 2.6% for infants delivered to US-born Black women and 2.4% for infants to Caribbean-born women compared with 0.7% for infants to US-born White women; the relative risk equaled 3.6 (95% CI: 3.1, 4.1) and 3.3 (95% CI: 2.5, 4.4), respectively. Among the lowest risk mothers, the relative risk of moderately low birth weight for infants with US-born Black mothers and Caribbean-born mothers (compared with US-born White mothers) was 2.7 (95% CI: 2.1, 3.4) and 1.2 (95% CI: 0.4, 3.1), respectively; the relative risk of very low birth weight for infants with US-born Black mothers and Caribbean-born mothers was 6.7 (95% CI: 3.8, 12) and 4.2 (95% CI: 1.0, 18), respectively. The authors conclude that Caribbean-born women and US-born Black women have disparate moderate rates but equivalent very low birth weight rates.     

Differences in low-birthweight among documented and undocumented foreign-born and US-born Latinas

In the USA foreign-born women tend to have fewer low-birthweight births than US-born women from the same ethnicity. This "healthy migrant" effect could be caused by immigration of the fittest or by healthy people being deliberately selected in the immigration process. This study tests these hypotheses by comparing self-reported history of low-birth-weight among foreign-born documented and undocumented Latinas and US-born Latinas. The sample includes 2398 (57.5%) documented foreign-born Latinas, 782 (18.7%) undocumented foreign-born Latinas, and 993 (23.4%) US-born Latinas who initiated prenatal care at MIC-Women's Health Services/MHRA in New York City during 1996-1997. Only women who reported previous live births were included in the sample. Documented foreign-born Latinas were less likely than US-born Latinas to have low-birth-weight babies taking into account parity, age, risk, and education. There were no significant differences between rates of low-birthweight for undocumented foreign-born Latinas and US-born Latinas, or documented foreign-born Latinas. There was, however, a significant trend for rates of low-birthweight to increase from documented foreign-born to undocumented foreign-born to US-born women. This suggests that both official screening and migration of the fittest play a role in lower rates of low-birthweight among foreign-born Latinas compared to US-born Latinas.     

Veneral infections in three ethnic groups in Sacramento.

Blacks treated in Sacramento County (CA) Clinics were most likely to have gonorrhea. Chicanos were slightly more likely to have nonspecific urethritis and other sexually transmitted diseases, and Whites were most likely to be uninfected. Whites tended to name greater numbers of different sexual partners, but differences among the three groups were not statistically significant. Black men more frequently reported to clinics with genitourinary symptoms and delayed significantly longer before seeking treatment. Future research should assess the relative contributions of sexual and health behaviors to the distributions of different sexually transmitted diseases in different groups.     

Differences in socioeconomic status and survival among white and black men with prostate cancer

After diagnosis with prostate cancer, Black men in the United States have poorer survival than White men, even after controlling for differences in cancer stage. The extent to which these racial survival differences are due to biologic versus non-biologic factors is unclear, and it has been hypothesized that differences associated with socioeconomic status (SES) might account for much of the observed survival difference. The authors examined this hypothesis in a cohort study, using cancer registry and US Census data for White and Black men with incident prostate cancer (n = 23,334) who resided in 1,005 census tracts in the San Francisco Bay Area during 1973-1993. Separate analyses were conducted using two endpoints: death from prostate cancer and death from other causes. For each endpoint, death rate ratios (Blacks vs. Whites) were computed for men diagnosed at ages <65 years and at ages > or =65 years. These data suggest that differences associated with SES do not explain why Black men die from prostate cancer at a higher rate when compared with White men with this condition. However, among men with prostate cancer, SES-associated differences appear to explain almost all of the racial difference in risk of death from other causes.     

Internalized racism and mental health among African-Americans,US-born Caribbean Blacks,and foreign-born Caribbean Blacks

Objectives. The tripartite model of racism includes personally mediated racism, institutionalized racism, and the less-oft studied internalized racism. Internalized racism – or negative beliefs about one’s racial group – results from cultural racism that is endemic in American society. In this project, we studied whether these negative stereotypes are associated with mental health among African-Americans and Caribbean Blacks.

Design. Using secondary data from the National Survey of American Life, we investigated the association between internalized racism and mental health (measured by depressive symptoms and serious psychological distress (SPD)) among these two groups. We also explored whether ethnicity/nativity and mastery moderate the association between internalized racism and mental health among African-Americans and Caribbean Blacks.

Results. Internalized racism was positively associated with depressive symptoms and SPD among all Black subgroups. However, internalized racism was a weaker predictor of SPD among foreign-born Caribbean Blacks than US-born Caribbean Blacks and US-born African-Americans. Additionally, higher mastery was protective against distress associated with internalized racism.

Conclusion. Internalized racism is an important yet understudied determinant of mental health among Blacks. Future studies should take into account additional heterogeneity within the Black population (e.g. African-born individuals) and other potential protective mechanisms in addition to mastery (e.g. self-esteem and racial identity).     

Profiles of depressive symptoms among African Americans and Caribbean Blacks

Latent profile analysis was used to summarize profiles of depressive symptoms among a nationally representative sample of US-born and Caribbean-born Blacks. Analyses are based on the responses of 4915 African Americans and Caribbean Blacks from the National Survey of American Life. A high symptoms and a low symptoms class were identified. Age, gender, negative interaction within the individual's social network (e.g., conflict, demands, criticism) and racial discrimination were associated with depressive symptoms in the low symptoms class, whereas socioeconomic status, gender, emotional support and negative interaction were associated with depressive symptoms in the high symptoms class. The findings demonstrate the heterogeneity within the Black population in the USA and the distinct sociodemographic, family network and stress correlates of depressive symptoms for each latent class.     

Reproductive health differences among Latin American- and US-born young women

Investigations of reproductive health within Lationos living in the United States suggest that sexual behaviors and contraception use practices vary by ethnicity and between foreign- and US-born adolescents. This article compares high-risk sexual behaviors and reproductive health among foreign-born Latinas, US-born Latinas, and US-born non-Latinas aged 15–24 years. We recruited 361 females from reproductive health clinics in the San Francisco Bay Area of California between 1995 and 1998; these women completed an interview that assessed sexual risk behaviors and history of pregnancy, abortion, and sexually transmitted infections. Current chlamydial and gonococcal infections were detected through biological testing. Among participants aged 15–18 years, US-born Latinas were more likely to have been pregnant (odds ratio [OR] comparing US-born Latinas and US-born non-Latinas=3.9, 95% confidence interval [CI] 1.3, 11.4), whereas among respondents aged 19–24 years, foreign-born Latinas were more likely to have been pregnant than US-born Latinas (OR=11.3, 95% CI 1.0, 130.8) and US-born non-Latinas (OR=64.2, 95%CI 9.9, 416.3). US-born Latinas were most likely to have had an abortion (OR comparing US-born Latinas and US-born non-Latinas=2.0, 95% CI 0.9, 4.7). They were also most likely to have chlamydial infection at study enrollment (8.2% prevalence compared to 2.2% and 1.0% for foreign-born Latinas and US-born non-Latinas, respectively; P=0.009). Reproductive health differences between foreign and US-born females and within the US-born population warrant further examination and highlight the need for targeted prevention.     

Influence of Nativity Status on Breast Cancer Risk Among US Black Women

Black women are at increased risk for breast cancer mortality. The black category is assumed to be homogeneous, an assumption that may be misleading. This study aims to examine the relationship between nativity and breast cancer risk factors among women identified as black. A sample of 236 black women over 18 years of age in Brooklyn, New York, was recruited. Data were collected on race/ethnicity, breast cancer risk factors, and other sociodemographic, behavioral, and early life experience factors. Logistic regression analyses were used to estimate prevalence ratios for association between nativity and breast cancer risk factors. US-born blacks were more likely to be unemployed, smoke, not breastfeed, and breastfeed for a shorter duration than foreign-born blacks (all p≤0.01). Foreign-born blacks were more likely to have parents who achieved at least a high school education (p<0.05). After adjustment for smoking, employment, and parental education, US-born blacks were twice as likely to never breastfeed (PR 2.2, 95% CI: 1.1, 4.46) compared to foreign-born blacks. Among women who breastfed, US-born blacks were also less likely to breastfeed for 6–11 months or more than 12 months, but these associations were not statistically significant. Because lactation reduces breast cancer risk and is a leading modifiable risk factor, understanding its variation within black women will help physicians and public health practitioners to target patient counseling and education of breast cancer risk.

HIV/AIDS Among African-Born Residents in the United States

The number of African-born residents living in the United States (US) increased by more than 750 % between 1980 and 2009. HIV diagnosis rates in this population are six times higher than estimated incidence in the general US population. African-immigrants with HIV are also diagnosed at later stages of infection than US-born residents, but they paradoxically have lower mortality after diagnosis. There are higher rates of HIV among women, higher rates of heterosexual transmission, and lower rates of injection-drug-use-associated transmission among African-born residents in the US relative to the general US population. Despite this distinct epidemiologic profile, surveillance reports often group African-born residents with US-born Blacks. The high rates of HIV among African-born residents in the US combined with increasing immigration and incomplete surveillance data highlight the need for more accurate epidemiologic data along with appropriate HIV service programs.     

Breast cancer screening and health behaviors among African American and Caribbean Women in New York City

A telephone-based survey regarding breast cancer screening practices among 300 African American and Caribbean women age 40 and over in New York City revealed that while U.S.-born women had significantly different sociodemographic profiles (in terms of insurance status, marital status, educational attainment), they were no more likely to have had a mammogram than the foreign-born women. Adjusting for insurance status and source of care, women with a provider recommendation were 8 times more likely ever to have had a mammogram (AOR 8.01, 95%CI: 3.74-17.14). Among foreign-born Caribbean women in the U.S. for less than half their lives, only 52% ever had a provider recommend a mammogram, compared with 77% of U.S.-born women. The findings confirm previous reports of the importance of physician recommendation in increasing mammography screening among urban Black women, and suggest that efforts to reach Caribbean-born women with breast cancer screening messages should emphasize the important role of providers.
