Diet and Acculturation Among Hispanic/Latino Older Adults in the United States: A Review of Literature and Recommendations

Among U.S. and foreign-born Hispanic/Latino older adults living in the United States, associations of dietary acculturation and health outcomes have yielded no consistent findings. The purpose of this review was to present current knowledge and research disparities on acculturation, dietary intake, and health outcomes among the fastest growing minority group in the United States. Fifteen peer-reviewed studies that measured dietary acculturation among Mexican, Puerto Rican, and Dominican older adults living in the United States were identified and examined. This literature review divulged contradictory associations between dietary acculturation and dietary intake, along with nutritional and general health outcomes. Conclusive evidence has yet to be attained due to use of cross-sectional study designs and numerous acculturation measures as well as unique cultural and dietary patterns across diverse Hispanic/Latino populations. Further research is needed to ascertain dietary acculturation among U.S. and foreign-born Hispanic/Latino older adults in the United States and should strive to develop instruments that consider the social, economic, and political environments that influence the dietary acculturation process. Furthermore, longitudinal study designs and qualitative methodologies are warranted.     

The Hispanic Community Children's Health Study/Study of Latino Youth (SOL Youth): design,objectives, and procedures

PurposeThis article describes the design and methodology of the Study of Latino Youth (SOL Youth) study, a multicenter study of Hispanic/Latino children living in the United States.MethodsParticipants are children aged 8–16 years whose parents/legal guardians participated in the Hispanic Community Health Study/Study of Latinos, a large community-based cohort study of Hispanic/Latino adults living in the United States.ResultsBetween 2012 and 2014, 1600 children recruited from four field centers (Bronx, Chicago, Miami, and San Diego) will undergo a 3.5-hour examination to collect biospecimens, obtain anthropometric measures, blood pressure, fitness level, dietary intake, and physical activity. Psychosocial and environmental characteristics are assessed by questionnaire. Primary study aims are to examine associations of youth's lifestyle behaviors and cardiometabolic risk factors with (1) youth's acculturation and parent-child differences in acculturation; (2) parenting strategies, family behaviors, and parental health behaviors; and (3) youth's psychosocial functioning.ConclusionsSOL Youth will determine the prevalence and distribution of obesity-promoting lifestyle behaviors, cardiometabolic risk profiles, and novel biomarkers associated with obesity and insulin resistance. This article describes the study methodology and considers advantages and limitations of embedding a cohort of children within a well-characterized cohort of adults.     

Intake and food sources of macronutrients among older Hispanic adults: association with ethnicity, acculturation, and length of residence in the United States

OBJECTIVE: To describe the food intake and food sources of macronutrients in diets of older Hispanic adults in the Northeastern United States and to explore relationships between acculturation, years in the United States, and macronutrient intake. DESIGN: Cross-sectional study using a representative sample of older Hispanic adults and a comparison group of non-Hispanic whites. SUBJECTS/SETTING: Hispanic (n = 711) and non-Hispanic white (n = 226) persons, aged 60 years and older, residing in Massachusetts. STATISTICAL ANALYSIS: Macronutrient intakes, collected by 24-hour dietary recall, were compared across ethnic groups by means of the general linear models procedure (with Bonferroni adjustments). Associations between macronutrient intake and predictor variables were tested with Pearson correlations and linear regression. The contribution of foods to total intake of macronutrients was determined by use of a rank procedure. RESULTS: Hispanic elderly subjects consumed significantly less saturated fat and simple sugars and more complex carbohydrates than did non-Hispanic whites. Hispanics residing in the United States for a longer time tended to have macronutrient profiles more similar to those of the non-Hispanic whites. Rice for Hispanic and bread for non-Hispanics were the major contributors of energy. More acculturated Hispanic elders consumed fewer ethnic foods and more foods related to the non-Hispanic-white eating patterns than those less acculturated. APPLICATIONS/CONCLUSIONS: Efforts to promote better diets among Hispanic elders need to emphasize maintenance or adoption of healthful dietary patterns based on ethnic and modern foods that will satisfy their biological, emotional, and social needs. Dietitians and other dietetics practitioners can use the information presented here in studying nutrition-related chronic diseases, in public health planning, and in nutrition education and promotion efforts directed to ethnic-specific, elderly Hispanic groups.     

Acculturation and sociocultural influences on dietary intake and health status among Puerto Rican adults in Massachusetts

BackgroundPrevious studies have shown the negative consequences of acculturation on lifestyle factors, health status, and dietary intake of Hispanic immigrants in the United States. Despite prevalent type 2 diabetes and low socioeconomic status among Puerto Rican adults living on the US mainland, little is known about acculturation in this group.ObjectiveWe investigated associations among acculturation, lifestyle characteristics, health status, and carbohydrate nutrition in Puerto Rican adults. A secondary objective was to investigate possible confounding and/or effect modification on these associations by socioeconomic status.DesignCross-sectional data from the Boston Puerto Rican Health Study, which included 1,219 Puerto Ricans in the Boston area, aged 45 to 75 years.Statistical analysesCharacteristics were compared using analysis of covariance, linear trend, and Pearson's χ² tests across quartiles of acculturation. Tests for interaction by poverty status were conducted. Proportional contributions of foods to intake of total carbohydrate and fiber were assessed using SAS RANK (version 9.1.3, 2002-2003, SAS Institute, Cary, NC).ResultsLevels of acculturation were low, despite young age at first arrival to the US mainland (25.4±12.3 years) and long length of stay (34.2±12.2 years). Greater English language use was associated with higher socioeconomic status, alcohol consumption, physical activity, better perceived health, and less central obesity. Acculturation was associated with lower legume fiber and greater cereal fiber intake. Among those above the poverty threshold, acculturation was associated with lower dietary glycemic index and starch intake, and greater fruit and nonstarchy vegetable intake.ConclusionsIn contrast to studies with Mexican Americans, the association of acculturation with dietary quality in these Puerto Rican adults was mixed, but tended toward better carbohydrate quality. Dietary recommendations should include maintenance of traditional, healthful dietary practices, including consumption of legumes, but also reduction in refined grains, and greater inclusion of fruit, nonstarchy vegetables, and whole grains. Interventions to improve access to better quality carbohydrate sources are necessary for this group disproportionately affected by diabetes.     

The role of acculturation in nutrition, lifestyle, and incidence of type 2 diabetes among Latinos

Latinos have become the largest ethnic minority group in the U.S. and will become 25% of the population by 2050. The purpose of this critical review is to examine the influence of acculturation on type 2 diabetes and corresponding risk factors, including 1) dietary intake, 2) physical activity patterns, 3) smoking and alcohol consumption, and 4) obesity. Among Latinos, acculturation has been associated with obesity risk, suboptimal dietary choices including lack of breast-feeding, low intake of fruits and vegetables, a higher consumption of fats and artificial drinks containing high levels of refined sugar, smoking, and alcohol consumption. In contrast, acculturation has been positively associated with physical activity and a lower likelihood of type 2 diabetes among Latinos. However, findings have been inconsistent across acculturation indicators and appear to be strongly modified by Latino subethnicity and gender. It is important to improve existing acculturation measures available. Mexican Americans have been the target group in the majority of studies. Research in this group must continue but it is important to conduct additional research with other Latino subgroups that have been left out of most of the acculturation, lifestyles, and health outcomes research. Differences between acculturation and health-related outcomes may be confounded by socio-economic status, age, and movement from urban to rural areas. Longitudinal multivariate acculturation research is essential to disentangle these relations and to develop sound behavioral change theories that adequately predict behavioral change among Latinos.     

A systematic review of the relationship between acculturation and diet among Latinos in the United States: implications for future research

Dietary intake is an important determinant of obesity and numerous chronic health conditions. A healthful diet is an essential component of chronic disease self-management. Researchers have indicated that the healthfulness of the Latino diet deteriorates during the acculturation process. However, given the many operationalizations of acculturation, conclusive evidence regarding this relationship is still lacking. This comprehensive and systematic literature review examines the relationship between acculturation and diet by examining national, quantitative, and qualitative studies involving Latinos living in the United States. Studies of diet included those that examined dietary intake using one of several validated measures (eg, food frequency questionnaire, 24-hour dietary recall, or dietary screener) and/or dietary behaviors (eg, away-from-home-eating and fat avoidance). Articles were identified through two independent searches yielding a final sample of 34 articles. Articles were abstracted by two independent reviewers and inter-rater reliability was assessed. Analyses examined the extent to which various measures of acculturation (ie, acculturation score, years in the United States, birthplace, generational status, and language use) were associated with macronutrient intake, micronutrient intake, and dietary behaviors. Several relationships were consistent irrespective of how acculturation was measured: no relationship with intake of dietary fat and percent energy from fat; the less vs more acculturated consumed more fruit, rice, beans, and less sugar and sugar-sweetened beverages. Additional observed relationships depended on the measure of acculturation used in the study. These findings suggest a differential influence of acculturation on diet, requiring greater specificity in our dietary interventions by acculturation status.     

Conceptions of acculturation: a review and statement of critical issues

This article reviews evidence for re-conceptualizing acculturation status and acculturation process in health care research with United States (U.S.) Latino populations. Prior literature on acculturation has focused on: (a) acculturative change towards the dominant culture, (b) acculturation as it occurs with Mexican Americans, and (c) language as the principal component of acculturation. We review empirically based health research on acculturation and propose an ecodevelopmental framework for better understanding the process of acculturation. We then offer recommendations that may assist public health researchers, policymakers and program developers in better understanding "real world" acculturation. This includes understanding acculturation within this ecodevelopmental context for a more complete understanding of the acculturation process and its influences on health-related behaviors, with aims of reducing or eliminating health disparities in Latino populations.     

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.     

The relationship of education and acculturation with vigorous intensity leisure time physical activity by gender in Latinos

Objectives: Latinos have poorer health outcomes among certain conditions (e.g. diabetes, obesity, mental health) compared to non-Latino Whites in the U.S., in part due to difference in the amount of physical activity, which are heavily influenced by sociocultural factors such as educational attainment and acculturation. Vigorous-intensity leisure time physical activity (VLTPA) may provide health benefits with a shorter amount of time than moderate-to-light physical activity. However, VLTPA has been significantly understudied compared to LTPA in general. The purpose of this study is to examine the associations between educational attainment, acculturation, and VLTPA by gender among Latino adults in the U.S.

Design: Nationally representative samples of Latino adults aged 25 years and older (n?=?4393) from the 2010 National Health Interview Survey were analyzed. VLTPA was measured as the number of hours per week of VLTPA consisting of heavy sweating or large increases in breathing and heart rate. Acculturation was measured as the degree to which the English language versus the Spanish language was spoken most often. The zero-inflated Poisson regression model was constructed using the full information maximum likelihood estimation and controlling for a series of sociodemographic characteristics and relevant health behaviors.

Results: Educational attainment was positively associated with VLTPA among Latino adults [exp(b)?=?1.09, p?b)?=?1.10, p?Conclusions: Education had a positive association and acculturation had negative association with the hours/week of VLTPA among Latinos. Also, the association between education and VLTPA was significantly stronger among women than men. These findings inform culturally and socially sensitive approaches to improve the health of Latinos, in hopes to address health disparities by race/ethnicity the U.S.     

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 and the sexual and reproductive health of Latino youth in the United States: a literature review

CONTEXT: The high birthrate among Latina teenagers in the United States has generated increased interest in the role of acculturation in their sexual and reproductive health. It is critical to identify gaps in the existing research and to ascertain the relationship between acculturation and Latino sexual behavior. METHODS: PUBMED, ERIC and POPLINE were searched for journal articles published between 1985 and 2006 that explicitly examined acculturation and sexual and reproductive health among Latino youth. All fertility-related outcomes (pregnancy, birth, abortion) and their proximate determinants (attitudes, knowledge, norms, sexual activity, contraceptive use) were considered sexual or reproductive health outcomes. Eligible studies used a cross-sectional or longitudinal design; had a sample of males, females or both aged 25 or younger; and included Latino-specific analyses. RESULTS: Seventeen studies met the screening criteria, and these studies used 23 distinct measures of acculturation that captured four primary dimensions: time (duration of exposure to U.S. culture), language, culture and residence. The measures' robustness varied, and none of the studies was widely generalizable. Ten studies investigated sexual initiation, and eight of these found a positive association between the likelihood of this outcome and acculturation. Acculturation also was associated with increased condom use and with beliefs and norms related to healthy outcomes, although the evidence was less conclusive. CONCLUSIONS: Ideal studies of acculturation would stratify analyses by gender and country of origin, and would include time measures related to acculturation. When feasible, studies should be population-based and longitudinal, and should build on existing theories of the relationship between acculturation and the sexual behavior, norms and beliefs that are unique to Latino culture.     

Toward a theory-driven model of acculturation in public health research

Interest in studying the impact of acculturation on immigrant health has increased in tandem with the growth of the Latino population in the United States. Linear assimilation models continue to dominate public health research despite the availability of more complex acculturation theories that propose multidimensional frameworks, reciprocal interactions between the individual and the environment, and other acculturative processes among various Latino groups. Because linear and unidimensional assessments (e.g., nativity, length of stay in the United States, and language use) provide constricted measures of acculturation, the rare use of multidimensional acculturation measures and models has inhibited a more comprehensive understanding of the association between specific components of acculturation and particular health outcomes. A public health perspective that incorporates the roles of structural and cultural forces in acculturation may help identify mechanisms underlying links between acculturation and health among Latinos.     

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.     

Acculturation and diabetes among Hispanics: evidence from the 1999-2002 National Health and Nutrition Examination Survey

OBJECTIVE: Hispanic individuals in the United States have a greater prevalence of diabetes mellitus than non-Hispanic white individuals; however, it is unclear whether Hispanics' risk of diabetes differs based on their level of acculturation. The purpose of our research was to examine acculturation among Hispanic Americans with respect to prevalence and control of diabetes. METHODS: We conducted an analysis of the National Health and Nutrition Examination Survey (NHANES), 1999-2002, a nationally representative sample of the noninstitutionalized U.S. population. We evaluated data on Hispanic adults (> or = 18 years of age, unweighted n=2,696), analyzing diagnosed diabetes, glycemic blood pressure and lipid control, and diabetes complications according to acculturation as measured by language and birth outside the United States. RESULTS: Hispanics with low acculturation were more likely to be without a routine place for health care, have no health insurance, and have low levels of education. In adjusted analyses, individuals with low acculturation, measured by language, were more likely to have diabetes (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.02, 3.54). Among individuals with diagnosed diabetes, no significant association was yielded between acculturation and diabetes control. However, individuals with low language acculturation were more likely to have the diabetes complication of peripheral neuropathy (OR 4.01, 95% CI 1.40, 11.48). CONCLUSIONS: Acculturation as measured through language is associated with diabetes and complications among Hispanics even after controlling for a variety of demographic characteristics including health insurance and education. The findings suggest that even within a "single" minority ethnic group, there are differences in disease prevalence and complications and access to health care.     

Ethnic variation in health and the determinants of health among Latinos

The purpose of this research is to document and explain ethnic variation in health among Latino adults in the United States. Results of analyses of data pooled from the 1997-2001 National Health Interview surveys reveal that health patterns are clearly different among Latino ethnic groups. Mexicans have health advantages, whereas Puerto Ricans experience health disparities. Cubans and Dominicans reveal a mix of health disparities and advantages, depending on the health outcome. The effects of social determinants of health are also contingent upon ethnicity. For example, worse health is associated with higher levels of socioeconomic status (SES) and acculturation among Mexicans, but with lower levels of SES and acculturation among Latinos whose origins are from Caribbean islands. We conclude that racial/ethnic comparative health research should avoid pan-ethnic groupings, and explicitly acknowledge ethnic group distinctiveness.     

Higher fat intake and lower fruit and vegetables intakes are associated with greater acculturation among Mexicans living in Washington State

OBJECTIVE: To examine associations of diet with acculturation among Hispanic immigrants from Mexico to Washington state and to compare dietary patterns of Hispanic with non-Hispanic white residents. DESIGN: Data are part of the baseline assessment for a community-randomized cancer prevention trial. The Fat-Related Diet Habits questionnaire and the National 5-A-Day for Better Health program dietary assessment instruments were used to collect data on fat and fruit and vegetable intake, respectively. Data were also collected on demographic characteristics and acculturation status. SUBJECTS/SETTING: A total of 1,689 adult Hispanic and non-Hispanic white residents of 20 communities in the Yakima Valley, WA, completed in-person interviews. STATISTICAL ANALYSES PERFORMED: Mixed model regression analyses tested associations of acculturation with diet. These models compared the fat and the fruit and vegetable intake of Hispanics vs non-Hispanic white residents. Additional analyses compared the diets of highly acculturated Hispanics with low-acculturated Hispanics. All models included age, sex, income, and education and were also adjusted for the random effect of community. RESULTS: Dietary patterns varied by ethnicity and acculturation status. On average, compared with non-Hispanic white residents, Hispanics consumed one more serving of fruits and vegetables per day (P<.001). Dietary habits changed as Hispanics acculturated to the United States. Highly acculturated Hispanics ate fewer servings of fruits and vegetables per day compared with those not highly acculturated (P<.05). Highly acculturated Hispanics had slightly higher, but not statistically significant, scores on the Fat-Related Diet Habits questionnaire, which corresponds to a higher fat intake, compared with low-acculturated Hispanics. The early dietary changes made on acculturation included adding fat at the table to breads and potatoes. APPLICATIONS/CONCLUSIONS: Nutrition professionals should encourage their Hispanic clients to maintain their traditional dietary practices, such as a high intake of fruits and vegetables and eating bread and potatoes without added fat.     

Dietary intake and risk of coronary heart disease differ among ethnic subgroups of black Americans

Coronary heart disease (CHD) morbidity and mortality are more prevalent in Blacks than Whites in the United States. Most studies evaluate the dietary intake and health of Black Americans as one group and do not consider possible differences among ethnic subgroups within the U.S. Black population. We used data from NHANES III to assess whether dietary intake, CHD risk factors, and predicted 10-y risk of CHD differed between non-Hispanic Black adults born in the United States (NHB-US), and non-Hispanic and Hispanic Black adults born outside of the United States (NHB-non US, HB-non US). Data were provided from single 24-h dietary recalls, biochemical measures, the medical examination, and self-reported responses to survey questions. NHB-US had higher intakes of energy, fat, protein, meat, added sugars, and sodium, and lower intakes of fruits, fiber, and most micronutrients. NHB-US also had higher predicted 10-y risk of developing CHD (5.8%) than NHB-non US (3.7%, P<0.001) or HB-non US (4.7%, P=0.017). Both immigrant groups had better CHD risk profiles and lower proportions of persons with metabolic syndrome and other CHD-related conditions. Our findings show differences in dietary intake and risk of CHD and related health conditions among ethnic subgroups of Blacks living in the United States. Future studies of diet and health should consider cultural differences within the Black population to better understand and reduce overall health disparities in the United States.     

Acculturation and smoking patterns among Hispanics: a review

OBJECTIVE: To conduct a systematic review of published studies investigating the association of acculturation and smoking patterns among Hispanic men and women in the United States. METHODS: Online bibliographic databases were searched from 1985 to 2003 using three key search terms. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study population, study methods, exposure assessment, outcomes measured, acculturation measures used, and results. RESULTS: The literature search identified 78 articles from MEDLINE, PubMed, and PsychINFO databases; of these, 11 studies met the inclusion criteria. Seven regional studies based in the western United States and four nationwide studies were included in the review. Seven studies used formal acculturation scales, three used language spoken, and one used language spoken and country of birth to indicate acculturation status. Nine studies showed a positive association between acculturation and smoking among women, and one study involving men showed a negative association. CONCLUSIONS: The findings suggest that the association of acculturation and smoking is gender-specific. In this instance, increased smoking prevalence with increased acculturation is consistently observed among Hispanic women but not among men. As Hispanic women acculturate, their cigarette smoking may increase because their behavior becomes more strongly influenced by the norms and practices of the dominant group than among men. Immigrant- and gender-specific public health interventions need to be designed to combat the increase in smoking rates among Hispanics in the United States.     

Acculturation, ethnic identity, and dating violence among Latino ninth-grade students

BACKGROUND: Studies of dating violence among Latino men and women have found that victims who are less acculturated have lower rates of dating violence. None of these studies have focused on adolescents. We assessed acculturation, ethnic identity, and dating violence victimization among Latino ninth-grade students. METHODS: Students from 13 high schools representing 24% of ninth-grade students in the Texas Lower Rio Grande Valley during 2000-2001 completed questionnaires. This analysis is restricted to students age 14 years or older who self-identified as Hispanic or Latino (n = 4,525). Logistic regression was performed to estimate the risk of dating violence associated with measures of acculturation and ethnic identity. RESULTS: Latino female adolescents were more likely to report dating violence victimization in the past 12 months (8.7%) than were males (6.4%). Parental birthplace outside of the United States was significantly associated with a reduced likelihood of dating violence victimization among females. Reporting a great deal of ethnic discrimination was strongly associated with increased dating violence victimization among females. CONCLUSIONS: These findings suggest that greater acculturation may be associated with greater prevalence of dating violence victimization among females. Understanding those aspects of Latino culture that may impact risk of dating violence could have important public health implications.     

Individual and Neighborhood Differences in Diet Among Low-Income Foreign and U.S.-Born Women

BACKGROUND: Research on the "immigrant" or "Latino health paradox" has demonstrated that Latinos exhibit better health than U.S.-born whites, for multiple health outcomes, despite adjusting for socioeconomic status. However, little empirical research has focused on women and even less has focused on how the neighborhood residential environment is associated with these health differences, particularly in the area of diet. METHODS: We analyzed baseline data from 641 low-income women, nested within 184 census tracts, enrolled in a nutrition intervention trial for postpartum women. Individual-level variables, including race/ethnicity, nativity, duration of time in the United States, language acculturation, emotional and instrumental support, and socioeconomic position, were merged with tract-level variables from U.S. Census data (2000) based on residential address. We assessed daily fruit and vegetable servings through a semiquantitative food frequency questionnaire. Using MLWin 2.0 software, we employed a 2-level linear regression model to ascertain associations of neighborhood immigrant, racial, and socioeconomic composition with individual diet, adjusting for individual-level sociodemographic characteristics. RESULTS: In our fully adjusted model, we observed a statistically significant increase of 1/3 of fruit and vegetable daily servings for each 10-percentage point increase in the tract foreign-born population. Each 10-percentage point increase in the tract Black population was associated with a significant 1/5 serving decrease in individual daily fruit and vegetable intake. CONCLUSIONS: Among this population of U.S. and foreign-born women, neighborhood composition was associated with individual diet, above and beyond individual-level characteristics, illuminating neighborhood context, immigrant health, and diet.
