Oral microbiota reveals signs of acculturation in Mexican American women.

The oral microbiome has been linked to a number of chronic inflammatory conditions, including obesity, diabetes, periodontitis, and cancers of the stomach and liver. These conditions disproportionately affect Mexican American women, yet few studies have examined the oral microbiota in this at-risk group. We characterized the 16S rDNA oral microbiome in 369 non-smoking women enrolled in the MD Anderson Mano a Mano Mexican American Cohort Study. Lower bacterial diversity, a potential indicator of oral health, was associated with increased age and length of US residency among recent immigrants. Grouping women by overarching bacterial community type (e.g., “Streptococcus,” “Fusobacterium,” and “Prevotella” clusters), we observed differences across a number of acculturation-related variables, including nativity, age at immigration, time in the US, country of longest residence, and a multi-dimensional acculturation scale. Participants in the cluster typified by higher abundance of Streptococcus spp. exhibited the lowest bacterial diversity and appeared the most acculturated as compared to women in the “Prevotella” group. Computationally-predicted functional analysis suggested the Streptococcus-dominated bacterial community had greater potential for carbohydrate metabolism while biosynthesis of essential amino acids and nitrogen metabolism prevailed among the Prevotella-high group. Findings suggest immigration and adaption to life in the US, a well-established mediator of disease risk, is associated with differences in oral microbial profiles in Mexican American women. These results warrant further investigation into the joint and modifying effects of acculturation and oral bacteria on the health of Mexican American women and other immigrant populations. The oral microbiome presents an easily accessible biomarker of disease risk, spanning biological, behavioral, and environmental factors.

Latent Profiles of Acculturation and Their Implications for Health: A Study With Asian Americans in Central Texas.

The present study identified profiles of acculturation in Asian Americans and explored their implications for health. Pointing out the upward selection bias of Asian Americans in English-only surveys, the study calls attention to the importance of obtaining Asian American samples that reflect the group's cultural and linguistic diversities. Data were drawn from 2,602 participants (age range = 18-98) in the 2015 Asian American Quality of Life (AAQoL) Survey, conducted in central Texas. To reach out to diverse groups of Asian Americans, culturally and linguistically sensitive approaches (e.g., survey questionnaire in Asian languages, bilingual/bicultural recruiters and survey assistants, and partnerships with key individuals and organizations within ethnic communities) were employed, resulting in a sample almost half of which were surveyed in their native languages. Latent profile analysis based on acculturation-related variables (nativity, proportion of life lived in the United States, English speaking ability, familiarity with host culture, familiarity with heritage culture, identity toward ethnic origin, and sense of belonging to the community of ethnic origin) identified a 4-cluster solution: fully bicultural, moderately bicultural, alienated from host culture, and alienated from heritage culture. The fully bicultural group was most advantaged in terms of self-ratings of physical, oral, and mental health. The alienated from heritage culture group demonstrated a particular risk for physical and mental health, whereas the alienated from host culture group was at risk for oral health. Findings not only help understand the heterogeneity of acculturation in Asian Americans but also provide implications for health interventions.

Health risk behaviors and depressive symptoms among Hispanic adolescents: Examining acculturation discrepancies and family functioning.

Drawing from a theory of bicultural family functioning 2 models were tested to examine the longitudinal effects of acculturation-related variables on adolescent health risk behaviors and depressive symptoms (HRB/DS) mediated by caregiver and adolescent reports of family functioning. One model examined the effects of caregiver-adolescent acculturation discrepancies in relation to family functioning and HRB/DS. A second model examined the individual effects of caregiver and adolescent acculturation components in relation to family functioning and HRB/DS. A sample of 302 recently immigrated Hispanic caregiver-child dyads completed measures of Hispanic and U.S. cultural practices, values, and identities at baseline (predictors); measures of family cohesion, family communications, and family involvement 6 months postbaseline (mediators); and only adolescents completed measures of smoking, binge drinking, inconsistent condom use, and depressive symptoms 1 year postbaseline (outcomes). Measures of family cohesion, family communications, and family involvement were used to conduct a confirmatory factor analysis to estimate the fit of a latent construct for family functioning. Key findings indicate that (a) adolescent acculturation components drove the effect of caregiver-adolescent acculturation discrepancies in relation to family functioning; (b) higher levels of adolescent family functioning were associated with less HRB/DS, whereas higher levels of caregiver family functioning were associated with more adolescent HRB/DS; (c) and only adolescent reports of family functioning mediated the effects of acculturation components and caregiver-adolescent acculturation discrepancies on HRB/DS.

Gender Matters: The Influence of Acculturation and Acculturative Stress on Latino College Student Depressive Symptomatology.

The purpose of the study was to examine the relationship between acculturation-related variables with depressive symptomatology among Latino college students and the extent to which acculturative stress mediates the association. The extent to which gender moderates these relationships was also examined. Participants were 758 Latina and 264 Latino college students from 30 colleges and universities around the United States. Participants completed measures of acculturation, acculturative stress, and depression. Multigroup path analysis provided excellent model fit and suggested moderation by gender. Acculturative stress mediated the acculturation-depression relationship. One indirect effect was moderated by gender with effects stronger for men: Heritage-culture retention to depressive symptoms via Spanish Competency Pressures. Acculturation and acculturative stress contribute to depression differently for male and female Latino college students. Future research should note the influence of gender socialization on the acculturation process and mental health.

Abstract 5038: Telomere length linking social contexts and cancer risk in Mexican Americans

Abstract Social contexts have a strong impact on chronic disease risk, including cancer, but how these influences “get under the skin” remains unclear. We hypothesize that telomere length may serve as the molecular link between social contexts and cancer risk. Using quantitative real-time PCR, we measured relative telomere length (TL) on baseline whole blood DNA samples collected from 6,574 participants of the ongoing Mano-a-Mano Mexican American Cohort study. We found that TL decreased linearly with increasing age (P-trend<0.001). In multivariable-adjusted Cox proportional-hazard regression models, longer TL was directly associated with a 2.66-fold increased risk of all-cancer incidence (95% CI= 1.40-5.03). TL was positively associated with several acculturation-related variables. For example, participants with a higher acculturative score with greater stays in the US had a longer TL among participants older than the median age of 38 (P=0.05 and 0.04, respectively). Participants born in the US and with at least a high school education were also more likely to have a longer TL. Among the modifiable risk factors, TL was inversely associated with sedentary or sitting time among women (P=0.01) and among young participants (P=0.01). In other chronic diseases, we found that longer TL was associated with diabetes and gallbladder disease in older participants (P=0.04 and 0.01, respectively). Our results suggest that TL may mediate the relationship between acculturation and related risk factors such as physical inactivity, education, and cancer risk among Mexican Americans. This is our first step in a continuum of research focused on understanding how social and behavioral disparities influence biological pathways in cancer development.

Change in Self-Reported Health Status among Immigrants in the United States: Associations with Measures of Acculturation

Although acculturation may have positive effects for immigrants, including better socioeconomic profiles and increased occupational opportunities, their health profiles deteriorate with longer duration in the U.S. Prior research indicates that increasing acculturation is associated with some poorer health outcomes among immigrants in the U.S. However, most of these studies have used length of stay or English language proficiency as proxies for acculturation, and have mainly examined self-reported “current” health outcomes. This study advances knowledge on associations between acculturation and health among immigrants by explicitly examining self-reported “change” in health since immigration, in relation to acculturation-related variables. We use data from the New Immigrant Survey (NIS; 2003-2004), a cross-sectional study of legal immigrants to the U.S. In addition to testing more conventionally examined proxies of acculturation (length of stay and English proficiency), we also examine English language use and self-reported change in diet. Multivariable logistic regression analyses on 5,982 participants generally supported previous literature indicating a deleterious impact of acculturation, with increasing duration of stay and greater self-reported change in diet being associated with a poorer change in health since moving to the U.S. Although English language proficiency and use were associated with greater odds of reporting a worse change in health when examined individually, they were non-significant in multivariable models including all acculturation measures. Findings from this study suggest that when taking into account multiple measures of acculturation, language may not necessarily indicate unhealthy assimilation and dietary change may be a pathway leading to declines in immigrant health. Increasing duration in the U.S. may also reflect the adoption of unhealthy behaviors, as well as greater exposure to harmful sources of psychosocial stress including racial and anti-immigrant discrimination. Our study suggests that multiple indicators of acculturation may be useful in examining the effect of acculturation on changes in health among immigrants.

Beyond Acculturation: An Investigation of the Relationship of Familism and Parenting to Behavior Problems in Hispanic Youth

In the adolescent research literature, acculturation processes have been linked to the development of serious behavior problems in Hispanic adolescents, but not enough is known about how that process takes place. This article reports an investigation that sought to shed light on empirically plausible mechanisms by which family processes (i.e., familism and parenting practices) may operate as mediators of acculturation-related factors on adolescent problem behaviors among 167 Hispanic sixth- or seventh-grade early adolescents. SEM analyses identified an empirically plausible mediated pathway through which parenting practices may operate as a mediator of the effects of acculturation-related variables on adolescent problem behaviors. Second, although the role of familism as a mediator was not supported, the results did provide support for familism having indirect effects on behavior problems also through parenting practices. The findings are discussed in the context of existing research and clinical developments in the treatment of Hispanic adolescents and families.

Culturally Sensitive Depression Assessment for Chinese American Immigrants: Development of a Comprehensive Measure and a Screening Scale Using an Item Response Approach.

The present mixed methods study developed a comprehensive measure and a screening scale of depression for Chinese American immigrants by combining an emic approach with item response analysis. Clinical participants were immigrants diagnosed by licensed clinicians who worked in the community. Qualitative interviews with clinicians and clinical participants (N = 63) supported the definition of the construct of depression-which guided scale development-and a 47-item pilot scale. Clinical and community participants (N = 227) completed the pilot scale and measures of neurasthenia and acculturative stress, and the Patient Health Questionnaire Depression Module (PHQ-9). A Rasch Partial Credit Model of 42-items-representing psychological, somatic and interpersonal domains of distress-best fit the data. Twenty-three items overlapped with the DSM-IV symptoms of major depression. Twenty-seven items were biased by acculturation-related variables. Nine items appropriate for self-report screening in primary care and community organizations were chosen to form a brief scale. Both measures showed strong reliability and concurrent and convergent validity. The 9-item scale had better content validity than the PHQ-9. Implications regarding the impact of culture for assessment are highlighted.

Change in Friendship Homophily

This longitudinal study investigated friendship homophily (i.e., the preference for intra-ethnic over inter-ethnic friends) among immigrant adolescents in Israel and Germany. Based on acculturation theories and known differences between Israel and Germany in the establishment of Russian-speaking immigrant communities in these countries, it was hypothesized that levels and rates of change in friendship homophily would differ. Associations between context- and acculturation-related variables and levels and rates of change in adolescent friendship homophily were also tested. The sample consisted of 877 Russian Jewish and 358 ethnic German Diaspora migrant adolescents (i.e., migrants returning to the country of their ancestors from the former Soviet Union). Results confirmed higher levels and a less pronounced decrease of friendship homophily in Israel as compared to Germany. Especially acculturation-related variables were found to be best at predicting intercept and slope of friendship homophily. Findings also showed that differences in levels and rates of change in adolescent friendship homophily between both countries could be explained by language use; thus, using the new host language more often appeared to be a crucial variable for lower levels of friendship homophily. Overall, results suggest very similar adaptation processes toward lower friendship homophily in the two countries but at a different pace over time.

Applying General Strain Theory to Examine Perceived Discrimination’s Indirect Relation to Mexican-Heritage Youth’s Alcohol, Cigarette, and Marijuana Use

Latent growth curve modeling was used to test four hypotheses. First, this study hypothesized that acculturation-related variables (e.g., Mexican-heritage youth's country of origin, time spent in the U.S., and language preference with family and friends) would be associated with initial levels of perceived discrimination. Guided by general strain theory (GST), this study then posed a second hypothesis: Initial levels of perceived discrimination would be indirectly related to initial levels of substance use through initial levels of acculturation stress. Third, this study hypothesized that changes in perceived discrimination would be indirectly related to changes in substance use through changes in acculturation stress. As a fourth hypothesis, it was postulated that initial levels of perceived discrimination would be indirectly related to changes in substance use through changes in acculturation stress. Mexican-heritage youth (N = 1,106) from 29 schools in Phoenix, AZ completed surveys at six waves from 5th through 8th grades. In partial support of the first hypothesis, more time spent in the U.S. and speaking English with friends were associated with lower levels of perceived discrimination. The second hypothesis was not supported. Initial levels of perceived discrimination were positively associated with initial levels of acculturation stress; however, this association was not found between initial levels of acculturation stress and substance use. The third and fourth hypotheses were supported, which buttressed predictions derived from GST. Both initial levels and increases in perceived discrimination were indirectly related to increases in substance use through increases in acculturation stress.

Acculturation and Violence in Minority Adolescents: A Review of the Empirical Literature

Although seminal reviews have been published on acculturation and mental health in adults and adolescents, far less is known about how acculturation influences adolescent interpersonal and self-directed violence. This article aims to fill this gap by providing a comprehensive review of research linking acculturation and violence behavior for adolescents of three minority populations: Latino, Asian/Pacific Islander (A/PI), and American Indian/Alaskan Native (AI/AN). The preponderance of evidence from studies on Latino and A/PI youth indicate that higher levels of adolescent assimilation (i.e., measured by time in the United States, English language use, U.S. cultural involvement, or individualism scales) were a risk factor for youth violence. Ethnic group identity or culture-of-origin involvement appear to be cultural assets against youth violence with supporting evidence from studies on A/PI youth; however, more studies are needed on Latino and AI/AN youth. Although some evidence shows low acculturation or cultural marginality to be a risk factor for higher levels of fear, victimization, and being bullied, low acculturation also serves as a protective factor against dating violence victimization for Latino youth. An important emerging trend in both the Latino and, to a lesser extent, A/PI youth literature shows that the impact of acculturation processes on youth aggression and violence can be mediated by family dynamics. The literature on acculturation and self-directed violence is extremely limited and has conflicting results across the examined groups, with high acculturation being a risk factor for Latinos, low acculturation being a risk factor of A/PI youth, and acculturation-related variables being unrelated to suicidal behavior among AI/AN youth. Bicultural skills training as a youth violence and suicide prevention practice is discussed.

Acculturation Among Three Racial/Ethnic Groups of Host and Immigrant Adolescents

This study compares Latino host, Latino immigrant, Asian-American host, Asian-American immigrant and European-American host groups of adolescents with respect to four acculturation-related variables: ethnic identity exploration, ethnic identity affirmation/belonging, outgroup orientation, and American identity. Using the five ethno-generational categories as a grouping variable, we conducted analyses of 313 survey responses to the acculturation items at two time periods, 9 weeks apart. Results showed that differences among the three host racial/ethnic groups can best be explained by a group dominance perspective, whereby the two racial/ethnic minority groups are more similar to each other than they are to the European-American group. Furthermore, the relationship between American identity and ethnic identity components is stronger among the three host groups, as compared to the immigrant groups. Implications for future research with adolescent members of the host group whose heritage culture is non-European are drawn.

The Validity of a Proxy Acculturation Scale Among U.S. Hispanics

This study examines the validity of a proxy acculturation scale composed of four acculturation-related variables. The authors use data from a nationally representative sample of 1,437 U.S. Hispanics. Results indicate good internal scale reliability, a high degree of correlation between the proxy scale and the full acculturation measure, and substantial agreement between dichotomized versions of the two scales. Although reliability declines slightly, validity increases with removal of generational status from the scale. Validity is found to be high for the three largest subpopulations by country of ancestry (Mexico, Puerto Rico, and Cuba). The proxy acculturation scale is a useful tool for the measurement of acculturation level among the majority of U.S. Hispanics when use of a more comprehensive acculturation scale is infeasible or impractical.

Correlates of Living Alone among Single Elderly Chinese Immigrants in Canada

According to traditional Chinese culture, families will care for their elderly. Therefore, it appears to be uncommon for elderly Chinese to live alone. This study examines the correlates for single elderly Chinese immigrants in Canada to live alone. Using a probability sample of single elderly Chinese immigrants (N = 660) in seven urban centers, hierarchical logistic regression analysis was performed to analyze the effects of socio-demographic resource variables, health, and cultural variables. The findings show that 39.1% of single elderly Chinese immigrants reported to be living alone. Variables related to resources, functioning capacity, and acculturation related variables are the key correlates for the elderly Chinese immigrants to maintain independence in the community. The findings imply a need to develop culturally sensitive programs to strengthen the social support, financial stability, and functioning capacity of the elderly immigrants.

Acculturation-Related Variables, Sexual Initiation, and Subsequent Sexual Behavior Among Puerto Rican, Mexican, and Cuban Youth.

The relationship among acculturation-related variables, past sexual activity, and subsequent sexual behavior was examined for a sample of Latino youth in the United States over a 12-month period. A subsample from the National Longitudinal Study of Adolescent Health database was analyzed by means of a prospective design. History of sexual intercourse predicted subsequent sexual behavior over the ensuing 12 months. The acculturation-related variables were related to whether an adolescent reported being sexually active at Wave 1 but in a complex fashion. Among recent immigrants, youth from English-speaking homes were less likely to be sexually active than those from Spanish-speaking homes. The opposite was observed for youth who were born in the United States or who had resided in the United States most of their lives.

Binge drinking among Latino youth: role of acculturation-related variables.

This research examined the relationship between acculturation-related variables and binge drinking behavior among nationally representative samples of Mexican American, Cuban American, and Puerto Rican youth. It explored the relationship between length of residence in the United States, type of language spoken in the home (Spanish vs. English) and binge drinking in each of these subgroups. Results suggest that Latino youths with no prior history of alcohol consumption remain largely unaffected by these acculturation-related variables. Youth with a previous history of alcohol consumption experience greater likelihood of binge drinking as a function of the acculturation-related variables, but the relationships are complex.
