Hispanic Health and Nutrition Examination Survey: methodological considerations

Proton Pump Inhibitor Use and Cognitive Function in the Boston Puerto Rican Health Study

BACKGROUND

There is a lack of consensus among studies on the association between proton pump inhibitor (PPI) use and cognitive impairment. This association is not well studied among minority populations, including among Puerto Ricans. Therefore, we sought to examine this association among Boston-area Puerto Ricans.

METHODS

The Boston Puerto Rican Health Study is an ongoing longitudinal cohort that enrolled 1499 Boston-area Puerto Rican adults, aged 45-75 years at baseline. Complete outcome and exposure data was available for 1290 baseline participants. Covariate-adjusted linear regression and linear mixed effects models were used to examine the association between PPI use, and global cognition, executive function, and memory cross-sectionally and longitudinally over ~12.7 years of follow-up. Furthermore, we examined the cross-sectional association between long-term PPI use (continuous use of ~6.2 years) and global cognition, executive function, and memory.

RESULTS

Among 1 290 participants at baseline, 313 (24.3%) self-reported PPI use. Baseline PPI use was not associated with baseline global cognition, executive function, or memory. Baseline PPI use also did not alter the trajectory of global cognition, executive function, or memory over ~12.7 years of follow-up. Long-term PPI use was not associated with global cognition, executive function, or memory over ~12.7 years of follow-up.

CONCLUSION

In this study of Boston-area Puerto Ricans, we did not observe an association between PPI use and global cognition, executive function, or memory either cross-sectionally or over 12.7 years of follow-up.

Endocrine Health and Health Care Disparities in the Pediatric and Sexual and Gender Minority Populations: An Endocrine Society Scientific Statement

Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

Critical data at the crossroads: the National Health and Nutrition Examination Survey faces growing challenges

NHANES needs urgent attention to ensure its future, which is facing emerging challenges associated with data collection, stagnant funding that has undercut innovation, and the increased call for granular data for subpopulations and groups at risk. The concerns do not rest merely on securing more funding but focus on the need for a constructive review of the survey to explore new approaches and identify appropriate change. This white paper, developed under the auspices of the ASN's Committee on Advocacy and Science Policy (CASP), is a call to the nutrition community to advocate for and support activities to prepare NHANES for future success in a changing nutrition world. Furthermore, because NHANES is much more than a nutrition survey and serves the needs of many in health fields and even commercial arenas, effective advocacy must be grounded in alliances among the survey's diverse stakeholders so that the full range of expertise and interests can engage. This article highlights the complicated nature of the survey along with key overarching challenges to underscore the importance of a measured, thoughtful, comprehensive, and collaborative approach to considering the future of NHANES. Starting-point questions are identified for the purposes of focusing dialog, discussion forums, and research. In particular, the CASP calls for a National Academies of Sciences, Engineering, and Medicine study on NHANES to articulate an actionable framework for NHANES going forward. With a well-informed and integrated set of goals and recommendations that could be provided by such a study, a secure future for NHANES is more readily achievable.

Ataque de nervios: The impact of sociodemographic, health history, and psychological dimensions on Puerto Rican adults

Introduction

Ataque de nervios (ADN) is a cultural syndrome prevalent in Puerto Ricans characterized as an episode of intense emotional upset due to overwhelming stress.

Methods

The Ataque de Nervios Questionnaire, developed at the Center for the Study and Treatment for Fear and Anxiety (CETMA), served as the diagnostic tool for this retrospective secondary data analysis. We evaluated three models regarding ADN's function as a marker of (1) sociodemographic vulnerability, (2) health history risk, and (3) psychological vulnerability. This last model was subdivided to assess the scores of screening tests regarding anxiety (Anxiety Sensitivity Inventory, Beck Anxiety Inventory, and State-Trait Anxiety Inventory), affect (Beck Depression Inventory, Emotional Dysregulation Scale, Positive and Negative Affective Schedule), personality (NEO Five-Factor Inventory), and trauma (considering the responses to the Childhood Trauma Questionnaire and the Life Event Checklist).

Results

Our study sample had a total of 121 Puerto Rican adult patients from CETMA out of which 75% had ADN. We differentiated subjects according to their ADN status with t-tests and Mann-Whitney U tests and evaluated our models using logistic regressions. People with ADN showed more anxiety, depressive symptoms, emotional dysregulation, and negative affect than those without ADN. They also revealed lower positive affect and agreeableness. Highly extraverted but minimally agreeable personalities related to ADN. Living with a partner and being employed were risk factors for ADN. Having higher educational levels showed the strongest effect size: it greatly reduced the odds of an ataque.

Discussion

These characteristics suggest a distinct profile of ADN seen in employed, educated, adult Puerto Ricans living on the Island experiencing anxiety. Our study provides clinical tools to comprehend our patients' ADN experience, enriching our practice as culturally competent health providers.

Food insecurity and physical functioning in Boston area Puerto Rican older adults

Objective:

Prior studies have found evidence of a relationship between food insecurity and functional limitations among older populations in the USA.

Design:

This is a longitudinal investigation of food security in relation to functional limitations, assessed as Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scores.

Setting:

The Greater Boston, MA area.

Participants:

1461 Boston Puerto Rican Health study participants, predominantly (70·5 %) female and aged 57·1 years (sd ± 7·6) at baseline followed for 6·2 (sd ± 0·98) years.

Results:

In cross-sectional analysis at baseline, participants reporting severe food insecurity had greater functional limitations (higher ADL; β = 2·34; 95 % CI (1·48, 3·19)) and higher IADL (β = 1·17, 95 % CI (0·68, 1·65)) compared with food secure participants. In longitudinal linear mixed models, severely food insecure participants at baseline had greater functional limitations over 5 years, as assessed by ADL (β = 1·74; 95 % CI (0·95, 2·53); P < 0·001) and IADL (β = 0·93, 95 % CI (0·48, 1·38)) compared with food secure participants. However, baseline food security did not significantly alter the 5-year trajectory in ADL (P-interaction between baseline food security and time for ADL and IADL = 0·41 and 0·47, respectively).

Conclusions:

In this cohort of Boston area Puerto Rican adults, those who are food insecure had consistently higher ADL and IADL scores over time, compared with those who are food secure. Baseline food security did not appear to alter the trajectory in ADL or IADL score.

From Sea to Shining Sea and the Great Plains to Patagonia: A Review on Current Knowledge of Diabetes Mellitus in Hispanics/Latinos in the US and Latin America

The past two decades have witnessed many advances in the prevention, treatment, and control of diabetes mellitus (DM) and its complications. Increased screening has led to a greater recognition of type 2 diabetes mellitus (type 2 DM) and prediabetes; however, Hispanics/Latinos, the largest minority group in the US, have not fully benefited from these advances. The Hispanic/Latino population is highly diverse in ancestries, birth places, cultures, languages, and socioeconomic backgrounds, and it populates most of the Western Hemisphere. In the US, the prevalence of DM varies among Hispanic/Latino heritage groups, being higher among Mexicans, Puerto Ricans, and Dominicans, and lower among South Americans. The risk and prevalence of diabetes among Hispanics/Latinos are significantly higher than in non-Hispanic Whites, and nearly 40% of Hispanics/Latinos with diabetes have not been formally diagnosed. Despite these striking facts, the representation of Hispanics/Latinos in pharmacological and non-pharmacological clinical trials has been suboptimal, while the prevalence of diabetes in these populations continues to rise. This review will focus on the epidemiology, etiology and prevention of type 2 DM in populations of Latin American origin. We will set the stage by defining the terms Hispanic, Latino, and Latin American, explaining the challenges identifying Hispanics/Latinos in the scientific literature and databases, describing the epidemiology of diabetes-including type 2 DM and gestational diabetes mellitus (GDM)-and cardiovascular risk factors in Hispanics/Latinos in the US and Latin America, and discussing trends, and commonalities and differences across studies and populations, including methodology to ascertain diabetes. We will discuss studies on mechanisms of disease, and research on prevention of type 2 DM in Hispanics/Latinos, including women with GDM, youth and adults; and finalize with a discussion on lessons learned and opportunities to enhance research, and, consequently, clinical care oriented toward preventing type 2 DM in Hispanics/Latinos in the US and Latin America.

Personalized medicine and Hispanic health: improving health outcomes and reducing health disparities - a National Heart, Lung, and Blood Institute workshop report

Persons of Hispanic/Latino descent may represent different ancestries, ethnic and cultural groups and countries of birth. In the U.S., the Hispanic/Latino population is projected to constitute 29% of the population by 2060. A personalized approach focusing on individual variability in genetics, environment, lifestyle and socioeconomic determinants of health may advance the understanding of some of the major factors contributing to the health disparities experienced by Hispanics/Latinos and other groups in the U.S., thus leading to new strategies that improve health care outcomes. However, there are major gaps in our current knowledge about how personalized medicine can shape health outcomes among Hispanics/Latinos and address the potential factors that may explain the observed differences within this heterogeneous group, and between this group and other U.S. demographic groups. For that purpose, the National Heart, Lung, and Blood Institute (NHLBI), in collaboration with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and the Food and Drug Administration (FDA), held a workshop in which experts discussed (1) potential approaches to study medical treatments and health outcomes among Hispanics/Latinos and garner the necessary evidence to fill gaps of efficacy, effectiveness and safety of therapies for heart, lung, blood and sleep (HLBS) disorders and conditions--and their risk factors; (2) research opportunities related to personalized medicine to improve knowledge and develop effective interventions to reduce health disparities among Hispanics/Latinos in the U.S.; and (3) the incorporation of expanded sociocultural and socioeconomic data collection and genetic/genomic/epigenetic information of Hispanic/Latino patients into their clinical assessments, to account for individual variability in ancestry; physiology or disease risk; culture; environment; lifestyle; and socioeconomic determinants of health. The experts also provided recommendations on: sources of Hispanic/Latino health data and strategies to enhance its collection; policy; genetics, genomics and epigenetics research; and integrating Hispanic/Latino health research within clinical settings.

Selecting an Acculturation Measure for Use With Latino Older Adults

The purpose of this article is to ascertain the degree to which acculturation measures have been validated for use with older Latino adults and to offer recommendations to assist practitioners and researchers in selecting an empirically sound acculturation measure. The authors analyzed the psycho-metric properties of 15 subjective acculturation instruments that sampled Latino older adult respondents in their development or validation. In general, the limited data suggest a tendency for lower acculturation scores among older Latinos. A number of scales suffer from methodological flaws or lack sufficient psychometric data. The effect of age on acculturation was infrequently analyzed, and no measure was designed specifically for use with older adults, although several measures appear to have promise for use with Latino older adults. Because Latinos are one of the fastest growing sectors of the older adult population, further attention to the development and validation of acculturation measures for this population is urged.

Test of a Nonlinear Relationship between Linguistic Acculturation and Ethnic Identification

Following a review of the literature concerning the relationship between acculturation (acquisition of a dominant culture) and ethnic identification (retention of culture of origin), the authors propose that linguistic acculturation is nonlinearly related to ethnic identity. An empirical study was conducted to test this relationship between linguistic acculturation and ethnic identification using data gathered from multiple studies investigating four different ethnic groups in Eastern Canada over a period of 7 years. Regression analysis results indicate that the two underlying dimensions of ethnicity are related and that the postulated function exhibits an excellent fit, thus providing support for the proposition.

Substance Use among Texas Hispanics and Non-Hispanics: Who's Using, Who's Not, and Why

The prevalence ofpast-yearand lifetime substance use, problem indicators, and the most important reasons for abstaining (among nonusers) were compared between Texas Hispanics and non-Hispanics, as well as among three subgroups of Hispanics who represented different levels of acculturation: Mexican born (i.e., least acculturated), U.S. born but relatively unacculturated, and U.S. born/highly acculturated. In general, prevalence rates among Hispanics increased as a function of U.S. acculturation, with the most acculturated group's rates more closely resembling non-Hispanics than Mexicanborn Hispanics. There were also significant variations by level of acculturation in the reasons given for abstinence. Whereas health was the most commonly cited reason for abstinence regardless of ethnicity, other important reasons (e.g., moral reasons versus influence of family and friends) varied significantly by ethnicity and acculturation. Results are interpreted with special regard to prevention.

Assessment of a Refined Short Acculturation Scale for Latino Preteens in Rural Colorado

Acculturation level was assessed among 137 fourth- and fifth-grade children in rural, southern Colorado, using the Short Acculturation Scale for Hispanic Youth (SASH-Y), a 12-point, unidimensional instrument adapted for this audience. Reliability was determined by test-retest (70.8% agreement) with a small subsample of this population. Eleven children were considered Mexican, 33 Mexican American, and 93 Euro-American. Analysis of the sample yielded a strong internal consistency (α=.89) and split-half reliability (.84). Based on factor analysis, personal language use, external language use, and ethnic social relations accounted for 82.6%, 13.5%, and 5.9% of all variance, respectively. Latino self-identification did not correlate with acculturation. The findings demonstrate that the SASH-Y, especially questions related to language use, is robust with a young, rural-based Latino population.

Association of diabetes with tooth loss in Hispanic/Latino adults: findings from the Hispanic Community Health Study/Study of Latinos

OBJECTIVES

To investigate the association between diabetes mellitus and missing teeth in Hispanic/Latino adults from diverse heritage groups who reside in the USA.

RESEARCH DESIGN AND METHODS

The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a multicenter, population-based study of 18-74 years old who underwent a physical and oral examination (n=15 945). Glycemic status was categorized as diabetes, impaired, or normal, based on medication use, and American Diabetes Association criteria for fasting glucose and glycosylated hemoglobin (HbA1c). HbA1c<7% indicated good glycemic control, and HbA1c>7% indicated uncontrolled diabetes. We estimated ORs and 95% CIs for missing >9 teeth and being edentulous (missing all natural teeth), after adjustment for age, income, education, Hispanic background, study site/center, nativity, last dental visit, health insurance, diet quality, cigarette smoking, obesity, periodontitis, and C reactive protein.

RESULTS

Persons with uncontrolled diabetes had a significant increased likelihood of missing >9 teeth and being edentulous as compared with persons with normal glycemic status (adjusted OR=1.92, 95% CI 1.44 to 2.55 and adjusted OR=1.73, 95% CI 1.22 to 2.46, respectively). The association appeared to be stronger at younger ages (18-44 years old; p for interaction <0.0001). However, we found no associations of either impaired glycemia or controlled diabetes with tooth loss in adjusted models.

CONCLUSIONS

Dentists should be aware of their Hispanic patients' diabetes status and whether or not they are well controlled, because these may affect tooth loss and impair oral function, which can lead to poor nutrition and complications of diabetes.

Challenges in preventing heart disease in hispanics: early lessons learned from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

The challenge of preventing cardiovascular disease (CVD) in US Hispanics depends upon being able to understand and communicate about the diversity within this population in terms of environmental exposures, health behaviors, socio-cultural experiences and genetic background to CVD risk factor profiles and disease burdens. Recent publications from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) launched by the National Institutes of Health (NIH) have begun to accomplish this task. In this article we review some of the HCHS/SOL findings concerning cardiometabolic and other CVD risk factors and relate them to the need for increased access to health care and attention to lifestyle variables including nutrition. A major challenge that needs to be accomplished is to alert our lawmakers, public health officials, health care providers and the Hispanic population at large about how to lighten the CVD risk factor and disease burdens now carried by our Hispanic population.

Are sleep symptoms predictors of resistant hypertension in a population-based sample? Findings from the National Health and Nutritional Examination Survey

The aim of this study was to test the association of self-reported sleep symptoms to those identified with severe hypertension in a nationally representative sample of adults. Self-reported and study-measured health and sleep characteristics were collected by the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2008. Of 10,526 individuals with completed sleep surveys participating in the study, the authors identified 379 patients with severe hypertension defined as those treated with ≥ 3 antihypertensive medications including a diuretic; 110 of these had resistant hypertension (RHTN) despite therapy, while 269 were controlled for severe hypertension (CSHTN). Patients with RHTN were more likely to be married, less educated, smoke, and self-report unsatisfactory health and diabetes when compared with patients with CSHTN. Multivariate analyses showed that poorly controlled diabetes (glycated hemoglobin >7%) was the strongest predictor of RHTN (odds ratio, 3.0; 95% confidence interval, 1.2-7.9). Unsatisfactory health (odds ratio, 1.7; 95% confidence interval, 1.7-2.7) was also associated with RHTN. Poorly controlled diabetes and self-reported unsatisfactory heath showed significant association with RHTN. Contrary to expectations, there was no significant association between self-reported snoring/snorting and RHTN, when other factors were examined. The association between poorly controlled diabetes and RHTN warrants further emphasis on strict control of diabetes in these individuals.

Lifetime risks of cardiovascular disease

BACKGROUND

The lifetime risks of cardiovascular disease have not been reported across the age spectrum in black adults and white adults.

METHODS

We conducted a meta-analysis at the individual level using data from 18 cohort studies involving a total of 257,384 black men and women and white men and women whose risk factors for cardiovascular disease were measured at the ages of 45, 55, 65, and 75 years. Blood pressure, cholesterol level, smoking status, and diabetes status were used to stratify participants according to risk factors into five mutually exclusive categories. The remaining lifetime risks of cardiovascular events were estimated for participants in each category at each age, with death free of cardiovascular disease treated as a competing event.

RESULTS

We observed marked differences in the lifetime risks of cardiovascular disease across risk-factor strata. Among participants who were 55 years of age, those with an optimal risk-factor profile (total cholesterol level, <180 mg per deciliter [4.7 mmol per liter]; blood pressure, <120 mm Hg systolic and 80 mm Hg diastolic; nonsmoking status; and nondiabetic status) had substantially lower risks of death from cardiovascular disease through the age of 80 years than participants with two or more major risk factors (4.7% vs. 29.6% among men, 6.4% vs. 20.5% among women). Those with an optimal risk-factor profile also had lower lifetime risks of fatal coronary heart disease or nonfatal myocardial infarction (3.6% vs. 37.5% among men, <1% vs. 18.3% among women) and fatal or nonfatal stroke (2.3% vs. 8.3% among men, 5.3% vs. 10.7% among women). Similar trends within risk-factor strata were observed among blacks and whites and across diverse birth cohorts.

CONCLUSIONS

Differences in risk-factor burden translate into marked differences in the lifetime risk of cardiovascular disease, and these differences are consistent across race and birth cohorts. (Funded by the National Heart, Lung, and Blood Institute.).

Language use and adherence to multiple cancer preventive health behaviors among Hispanics

Hispanics have lower cancer mortality rates than non-Hispanic Whites and Blacks, despite demographic profiles previously associated with higher cancer mortality. Differences in adherence to multiple cancer-preventive behaviors by acculturation may offer one explanation for this "Hispanic paradox," but the relationship is not well understood. We examined this relationship using the 2000 National Health Interview Survey, which provides cross-sectional data on a nationally representative sample of US Hispanics. Multinomial logistic regression models estimated relationships between language use (a measure of acculturation) and patterns of adherence, by gender, to multiple cancer-preventive health behaviors using adherence scores. Hispanics had greater odds of adherence to multiple behaviors compared to Non-Hispanics (OR = 2.76 [2.27, 3.36]). Hispanics with greater English language use had lower odds of adherence (OR = 0.45 [0.29, 0.69]). Women were more adherent than men (P < 0.01) and their language use was associated with patterns of behavioral adherence more so than among men. Differences by gender and language use were identified in patterns of adherence to behavioral recommendations among the Hispanic population. Greater English language use was negatively associated with tobacco, alcohol, fruit and vegetable recommendation adherence but not with exercise. Study findings support evidence behaviors occur in combination and contributes to understanding of the role of language use in patterns of behavioral adherence.

An exploration of differences in sleep characteristics between Mexico-born US immigrants and other Americans to address the Hispanic Paradox

STUDY OBJECTIVES

Decreased sleep duration and quality are associated with poor health. Given that Mexico-born US immigrants (MI) often have favorable health status relative to the general US population (USALL), we tested the hypothesis that MI have better sleep as compared to USALL and to Mexican-Americans (MA) born in the US.

RESEARCH DESIGN AND METHODS

Cross-sectional analysis of a stratified multistage probability sample of 18 years and older civilian non-institutionalized USALL enrolled in NHANES during 2005-2006. Age-adjusted population prevalence rates and adjusted odd ratios of short habitual sleep time (SHST) and insomnia were calculated using weighted analyses.

SETTING

Computer assisted personal bilingual (English/Spanish) interviews in the participants' home using a sleep questionnaire.

PARTICIPANTS

5160 USALL participants, including 1046 MA, of whom 620 were MI.

RESULTS

In logistic regression models unadjusted and adjusted for socioeconomic characteristics, health related behavior risk factors, health status, and depression, MI status was significantly associated with lower odds of SHST (OR = 0.7, 95%CI [0.6-0.9]), insomnia (OR = 0.3, 95%CI [0.2-0.5]), and sleep-associated functional impairments (OR = 0.4, 95%CI [0.2-0.8]). In MA males, MI status was associated with reduced odds of SHST < 7 h/weeknight and insomnia symptoms. Cultural changes measured by increased levels of English compared to Spanish language spoken at home were associated with an increased risk of poor sleep in MA men in univariate models, and may partially explain better sleep in MI men compared to their US-born counterparts.

CONCLUSION

Compared to the general US poplulation, Mexican-born US immigrants have more favorable sleep, possibly contributing to their lower reported risk of diabetes, hypertension, CVD, and all-cause mortality (the "Hispanic Paradox").

Relationship between perceived stress and dietary and activity patterns in older adults participating in the Boston Puerto Rican Health Study

Previous research supports a relationship between psychological stress and chronic disease in Puerto Rican adults living in the Boston, Massachusetts area. Stress may affect health by influencing dietary and physical activity patterns. Therefore, perceived stress and two hypothesized mediators of stress-related food intake, insulin and cortisol, were examined for possible associations with dietary and activity patterns in >1300 Puerto Ricans (aged 45-75 years; 70% women) living in the Boston, Massachusetts area. Data were analyzed using multiple linear regression and ANCOVA. Greater perceived stress was associated with lower fruit, vegetable, and protein intake, greater consumption of salty snacks, and lower participation in physical activity. Stress was associated with higher intake of sweets, particularly in those with type 2 diabetes. Cortisol and stress were positively associated in those without diabetes. Cortisol was associated with higher intake of saturated fat and, in those with diabetes, sweet foods. Independent of diabetes, perceived stress was associated with higher circulating insulin and BMI. Our findings support a link between stress, cortisol, and dietary and activity patterns in this population. For high-sugar foods, this relationship may be particularly important in those with type 2 diabetes. Longitudinal research to determine causal pathways for these identified associations is warranted.

Maternal predictors of behavioral problems among Mexican migrant farmworker children

This study investigated the impact of maternal parenting factors on the emotional and behavioral health of Mexican Migrant Head Start children. Although the majority of children sampled in this study did not exhibit problematic behaviors, the findings concluded that children who demonstrated emotional and behavioral problems experienced a more rejecting maternal parenting style, greater parenting stress, and mothers reporting feelings of depression. Gender differences were found between the behavioral and emotional problems of sons and daughters. Surprisingly, years in the United States, maternal birthplace, income, education, and language spoken in the home were not associated with child behavioral problems.

Allostatic load is associated with chronic conditions in the Boston Puerto Rican Health Study

Puerto Ricans living in the United States mainland present multiple disparities in prevalence of chronic diseases, relative to other racial and ethnic groups. Allostatic load (AL), or the cumulative wear and tear of physiological responses to stressors such as major life events, social and environmental burden, has been proposed as a possible mechanism for the inequalities observed in minority groups, but has not been studied in Puerto Ricans. The aim of this study was to determine the association of AL to six chronic diseases (abdominal obesity, hypertension, diabetes, and self-reported cardiovascular disease (CVD), arthritis and cancer) in Puerto Ricans, and to contrast AL to metabolic syndrome (MetS). Participants of the Boston Puerto Rican Health Study (n=1116, ages 45-75 years) underwent a home-based interview, where questionnaires were completed and biological samples collected. A summary definition of AL was constructed using clinically-defined cutoffs and medication use for 10 physiological parameters in different body systems. Logistic regression models were run to determine associations between AL score and disease status, controlling for age, sex, smoking, alcohol use, physical activity, total fat intake and energy intake. Parallel models were also run with MetS score replacing AL. We found that increasing categories of AL score were significantly associated with abdominal obesity, hypertension, diabetes and self-reported cardiovascular disease (CVD) and arthritis, but not with self-reported cancer. The strength of associations of AL with all conditions, except diabetes and cancer, was similar to or larger than those of MetS score. In conclusion, Puerto Rican older adults experienced physiological dysregulation that was associated with increased odds of chronic conditions. AL was more strongly associated with most conditions, compared to MetS, suggesting that this cumulative measure may be a better predictor of disease. These results have prospective research implications for Puerto Ricans and other ethnic groups.

Latina self-reported mental health and delay in health care in a new Latino destination

Understanding how depression and/or anxiety affects use of health care among Latinas in rapidly growing new Latino destinations, population where the growth rate of the Latino population exceeds the national average, may enhance community engagement efforts. Using community-based participatory research, a questionnaire assessing health care use was administered to 289 Latinas. Most (70%) reported delaying healthcare, and self-reported depression/anxiety was associated with a 3.1 fold (95% CI: 1.6-5.9) increase in delay, after adjusting for current health status, acculturation, age, education, and place of birth. Mental health disparities exist among Latinas, which are related to delays in use of health care. A gap exists regarding health education interventions for Latinas. More research is needed to identify successful models, especially in new Latino destinations as they may be particularly vulnerable to delay care.

Feasibility of collecting biologic specimens in population-based surveys: experiences from the epidemiology of hepatitis C in the household, adult population of Puerto Rico study

The Behavioral Risk Factor Surveillance System (BRFSS) collects data on preventive health practices and risk behaviors that are linked to chronic diseases, injuries, and preventable infectious diseases that affect the adult population in all states and territories in the US. The BRFSS is currently the only survey conducted annually in Puerto Rico in the population aged 18 years and older; however, prevalence estimates are based on self-reports and therefore are subject to reporting errors. Although surveillance data are useful for the purpose of evaluation, program planning and health policy, surveys that collect biological specimens and clinical data provide a more accurate assessment of prevalence and a comprehensive picture of disease distribution and their risk factors. This article summarizes the methodology employed in a population-based study to estimate the seroprevalence of hepatitis C and other viral infections in Puerto Rico and shows the feasibility of combining different modes of data collection in population-based surveys that collect biologic specimens.

The Boston Puerto Rican Health Study, a longitudinal cohort study on health disparities in Puerto Rican adults: challenges and opportunities

BACKGROUND

The Boston Puerto Rican Health Study is an ongoing longitudinal cohort study designed to examine the role of psychosocial stress on presence and development of allostatic load and health outcomes in Puerto Ricans, and potential modification by nutritional status, genetic variation, and social support.

METHODS

Self-identified Puerto Ricans, aged 45-75 years and residing in the Boston, MA metro area, were recruited through door-to-door enumeration and community approaches. Participants completed a comprehensive set of questionnaires and tests. Blood, urine and salivary samples were extracted for biomarker and genetic analysis. Measurements are repeated at a two-year follow-up.

RESULTS

A total of 1500 eligible participants completed baseline measurements, with nearly 80% two-year follow-up retention. The majority of the cohort is female (70%), and many have less than 8th grade education (48%), and fall below the poverty level (59%). Baseline prevalence of health conditions is high for this age range: considerable physical (26%) and cognitive (7%) impairment, obesity (57%), type 2 diabetes (40%), hypertension (69%), arthritis (50%) and depressive symptomatology (60%).

CONCLUSIONS

The enrollment of minority groups presents unique challenges. This report highlights approaches to working with difficult to reach populations, and describes some of the health issues and needs of Puerto Rican older adults. These results may inform future studies and interventions aiming to improve the health of this and similar communities.

Cigarette smoking among adult Latinos: the California Tobacco Baseline Survey

This article presents probability estimates of smoking prevalence for the Latino adult population in California and examines differences in smoking prevalence and nicotine dependence between different levels of education and acculturation and between different ethnic and gender groups. Prevalence estimates are based on the California Baseline Tobacco Survey (CTS). The CTS is a Random Digit Dial Survey including N=70,997 non-Latino Whites and 28,000 Latino adults. Overall smoking prevalence among Latinos was estimated at 24.4% for men and 12.0% for women. Multiple logistic regression analyses suggest higher smoking prevalence and higher nicotine dependence for men than for women, for individuals who have not finished high school, for non-Latinos when compared to Latinos, and for Latinos of high level of acculturation when compared to Latinos of low level of acculturation. These estimates can serve as baselines to evaluate progress toward year 2000 health objectives. Findings stress the importance of taking into account socio-economic level when comparing Latinos and other ethnic groups on health behaviors. Moreover, findings suggest that interventions helping Latinos quit smoking are most needed for men with twelve years or less of formal education and stress the importance of programs to prevent smoking uptake, specifically among Latinos of low level of acculturation.

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.

Chronic obstructive pulmonary disease in Hispanics

Hispanics are individuals whose ancestry can be traced to Spain and/or areas previously under Spanish control (e.g., Mexico, Puerto Rico). They are a rapidly growing subset of the population of the United States and are quite diverse in their racial ancestry, country of origin, area of residence, socioeconomic status, tobacco use, and access to health care. Current evidence suggests that the prevalence and morbidity of chronic obstructive pulmonary disease (COPD) vary widely among Hispanic-American nations, with similar but limited findings among Hispanic subgroups in the United States. Potential reasons for such variation include differences in racial ancestry and genetic susceptibility, exposure to tobacco smoke and/or biomass smoke, access to health care, and disease management. Future studies of COPD in Hispanics should include large samples of subgroups that are well defined with regard to self-reported ethnicity, country of origin, area of residence, tobacco use, and socioeconomic status. Areas that need to be carefully examined include validation of COPD diagnoses for epidemiologic studies (e.g., by radiologic assessment), COPD in high-risk groups (e.g., Puerto Ricans), impact of biomass smoke (in rural areas) and air pollution (in urban areas) on COPD morbidity, effects of migration and acculturation on COPD prevalence and morbidity among Hispanic subgroups in the United States, development of reference values for spirometry, smoking cessation, and overcoming barriers to management. Public health measures, such as effective smoking prevention and cessation programs, reduction of air pollution and exposure to biomass smoke, and improved access to health care, would help reduce the burden of COPD among Hispanics in the United States and Latin America.

Prevalence of self-reported diabetes and exposure to organochlorine pesticides among Mexican Americans: Hispanic health and nutrition examination survey, 1982-1984

BACKGROUND

The prevalence of diabetes is higher among Mexican Americans than among non-Hispanic whites. Higher serum levels of organochlorine pesticides in Mexican Americans have been reported. Few studies have explored the association between pesticide exposure and diabetes.

OBJECTIVES

We set out to examine the association between self-reported diabetes and serum concentrations of organochlorine pesticides among Mexican Americans residing in the southwestern United States from 1982 to 1984.

METHODS

This study was conducted among a sample of 1,303 Mexican Americans 20-74 years of age from the Hispanic Health and Nutrition Examination Survey. Serum concentrations were available for seven pesticides or pesticide metabolites at quantifiable levels in at least 1% of the study population: p,p'-DDT (dichlorodiphenyltrichloroethane), p,p'-DDE (dichlorodiphenyldichloro-ethylene), dieldrin, oxychlordane, beta-hexachlorocyclohexane, hexachlorobenzene, and trans-nonachlor. We used logistic regression to evaluate the association of self-reported diabetes with exposure to organochlorine pesticides, with and without adjustment for total serum lipids. Nonfasting serum glucose values were compared among exposure groups.

RESULTS

Self-reported diabetes was significantly associated with serum levels above the detectable limit for trans-nonachlor, oxychlordane, and beta-hexachlorocyclohexane and among those with the highest level of exposure to p,p'-DDT and p,p'-DDE. On adjustment for total serum lipids, the association with p,p'-DDT remained significant. Serum glucose levels were elevated among those exposed to trans-nonachlor and beta-hexachlorocyclohexane.

CONCLUSION

This study suggests that higher serum levels of certain organochlorine pesticides may be associated with increased prevalence of diabetes. Additional studies with more extensive clinical assessment are needed to confirm this association.

High blood pressure trends in children and adolescents in national surveys, 1963 to 2002

BACKGROUND

Secular trend data on hypertension in children and adolescents are scarce and inconsistent. In the face of growing obesity, we sought to assess high blood pressure (HBP) secular trends in children and adolescents enrolled in national surveys and to determine whether the HBP trend reversed its course with the rise in obesity.

METHODS AND RESULTS

National survey data obtained from multistage probability sampling of the US noninstitutionalized population from 1963 to 2002 were examined; 8- to 17-year-old non-Hispanic blacks and whites and Mexican Americans were included. HBP ascertainment was based on age-, gender-, and height percentile-specific systolic and diastolic BPs. Weighted analyses were performed to account for the complex design. The BP, pre-HBP, and HBP trends were downward from 1963 to 1988 and upward thereafter. Pre-HBP and HBP increased 2.3% (P=0.0003) and 1% (P=0.17), respectively, between 1988 and 1999. Obesity increase, more so abdominal than general obesity, partially explained the rise in HBP and pre-HBP from 1988 to 1999. BP and HBP reversed their downward trends 10 years after the increase in the prevalence of obesity. Additionally, an ethnic and gender gap appeared in 1988 for pre-HBP and in 1999 for HBP; non-Hispanic blacks and Mexican Americans had a greater prevalence of HBP and pre-HBP than non-Hispanic whites, and males had a greater prevalence than females.

CONCLUSIONS

HBP and pre-HBP in children and adolescents are on the rise. These new findings have implications for the cardiovascular disease public health burden, particularly the risk of a new cardiovascular disease transition. They reinforce the urgent call for early prevention of obesity and HBP and illustrate racial/ethnic disparities in this age group.

Acculturation in Mexican immigrants: a concept analysis

The concept of acculturation in Mexican immigrants was analyzed using the concept analysis technique developed by Walker and Avant. The related concepts for acculturation are assimilation, separation, and marginalization. The defining attributes identified for acculturation are original cultural identity, exposure to a culture different from one's own, and changes in the behavioral, affective, and/or cognitive domains of one's functioning after exposure to a new culture. An antecedent for acculturation is that identification with one's culture of origin must be well established. Another antecedent is the willingness to modify one's original cultural identity. Transition is identified as a consequence of acculturation. Acculturation is a complex, multifaceted concept and cannot be adequately captured by measures that use language preference alone. Other factors such as social class, employment, education, and income should also be considered when acculturation is a factor in nursing practice and research.

Hearing loss in migrant agricultural workers

BACKGROUND

Farmers have high rates of hearing loss, yet little is known about the hearing status of migrant agricultural workers. We performed a cross-sectional survey to assess the prevalence and impact of hearing loss in this population.

METHODS

One hundred fifty migrant and seasonal agricultural workers were surveyed at a series of health fairs held at migrant camps. A bilingual questionnaire included items related to hearing loss risk factors and subjective hearing difficulties. Pure tone audiometry and tympanometry were performed in a mobile testing van.

RESULTS

More than half the subjects had some degree of hearing loss at audiometric frequencies between 500 and 6,000 Hz, especially in the higher frequencies. Hispanic males in the sample had significantly greater prevalence of high-frequency hearing loss compared to adults in the national Hispanic Health and Nutrition Examination Survey (HHANES). More than 35% of respondents complained of subjective difficulty hearing or understanding speech, yet no workers reported use of hearing aids. Even after adjusting for measured hearing loss, Hispanic farm workers were more likely than their English- speaking counterparts to complain of difficulty hearing or understanding speech, suggesting that language barriers could worsen the impact of hearing loss. Risk factors for hearing loss included age and abnormal tympanometry. Occupational exposures to noise from tractors and other machinery as well as pesticides were frequently reported, while use of hearing protection was rare.

CONCLUSION

Hearing loss is a significant and under-recognized problem in the migrant worker population. Further preventive and treatment efforts are warranted.

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.

Age at natural menopause and exposure to organochlorine pesticides in Hispanic women

A cross-sectional study was conducted to evaluate the relationship between exposure to selected organochlorine pesticides (OCP) (p,p'-DDT, p',p'-DDE, dieldrin, hexachlorobenzene, beta-hexachlorocyclohexane [beta-HCH], oxychlordane, trans' nonachlor) and age at natural menopause in a sample of 219 menopausal women participating in the Hispanic Health and Nutrition Examination Survey in 1982-1984. Information on age at menopause, reproductive history, demographic variables, and potential confounding variables was collected via interview. Analysis of variance was employed to compare adjusted mean age at natural menopause among women by category of serum OCP level. Serum levels of p,p'-DDT, p,p'-DDE, beta-HCH, and trans-nonachlor were associated with a younger age at menopause. In particular, women with exposure levels in the highest exposure categories (serum p,p'-DDT > or = 6ppb, beta-HCH > or = 4ppb, or trans-nonachlor > or = 2ppb) had an adjusted mean age at menopause on average 5.7, 3.4, and 5.2 yr earlier, respectively, than women with serum levels of these pesticides below the detection limit. Women with serum p,p'-DDE levels greater than 23.6 ppb (highest quintile) had an adjusted mean age at menopause 1.7 yr earlier than women with serump,p'-DDE levels less than 5.5 ppb (lowest quintile). However, no consistent dose-response effect was apparent across low, medium, and high exposure categories. Interactions were detected for p,p'-DDT in combination with beta-HCH, trans-nonachlor, or oxychlordane, as well as beta-HCH in combination with oxychlordane.

Tuberculosis and diabetes in southern Mexico

OBJECTIVE

To determine the impact of diabetes on the rates of tuberculosis in a region where both diseases are prevalent.

RESEARCH DESIGN AND METHODS

Data from a population-based cohort of patients with pulmonary tuberculosis undergoing clinical and mycobacteriologic evaluation (isolation, identification, drug-susceptibility testing, and IS6110-based genotyping and spoligotyping) were linked to the 2000 National Health Survey (ENSA2000), a national probabilistic, polystage, stratified, cluster household survey of the civilian, noninstitutionalized population of Mexico.

RESULTS

From March 1995 to March 2003, 581 patients with Mycobacterium tuberculosis culture and fingerprint were diagnosed, 29.6% of whom had been diagnosed previously with diabetes by a physician. According to the ENSA2000, the estimated prevalence of diabetes in the study area was 5.3% (95% CI 4.1-6.5). The estimated rates of tuberculosis for the study area were greater for patients with diabetes than for nondiabetic individuals (209.5 vs. 30.7 per 100000 person-years, P < 0.0001).

CONCLUSIONS

In this setting, the rate of tuberculosis was increased 6.8-fold (95% CI 5.7-8.2, P < 0.0001) in patients with diabetes due to increases in both reactivated and recently transmitted infection. Comorbidity with diabetes may increase tuberculosis rates as much as coinfection with human immunodeficiency virus (HIV), with important implications for the allocation of health care resources.

Parent-reported asthma in Puerto Rican children

We conducted a survey to determine parent-reported asthma prevalence, morbidity, and healthcare utilization among 3527 children attending public schools (n = 2849) and private schools (n = 678) in San Juan, Puerto Rico. Schools were randomly selected from each of 12 geographic regions of the San Juan metropolitan area. Parents of children age 4-7 years old completed a 12-item questionnaire on asthma diagnosis, respiratory symptoms and morbidity, and healthcare utilization. Parents of children in public schools and private schools reported similar rates of a physician having previously diagnosed asthma in their children (43.2% vs. 39.4%); however, significantly more children in public schools were reported to still have asthma at the time of the survey (32.6% vs. 23.7%). Children attending public schools vs. private schools were reported to have missed significantly more school and to have had more hospitalizations and emergency department visits. Among children reported to still have asthma, significantly more children visited an emergency department, were hospitalized, and missed more school days due to respiratory symptoms in the past year. The high prevalence of parent-reported asthma, respiratory symptoms, and healthcare utilization among Puerto Rican children in San Juan calls for further studies using objective methods for ascertaining asthma and asthma-related morbidity. Differences in healthcare utilization between children attending public vs. private schools suggest that socioeconomic factors play a role in asthma management in Puerto Rico.

Risk factors for hysterectomy among Mexican-American women in the US southwest

The purpose of this study was to assess risk factors associated with a history of hysterectomy among Mexican-American women living in the United States Southwest. Mexican-American women ages 20-74 at time of interview were defined as a subpopulation among adults in the Hispanic Health and Nutrition Examination Survey (HHANES), 1982-1984. Language preference, reproductive history, level of education, poverty status, generation of immigration, marital status, and insurance coverage were examined in relation to risk of hysterectomy using weighted tabulation and logistic regression for data resulting from complex survey designs. Heretofore, language preference has not been a variable considered in relation to risk of hysterectomy. In the HHANES, over 60% of women who spoke English most often rather than Spanish reported a history of hysterectomy. Women who had previously been pregnant were almost four times as likely (odds ratio 3.972) to have had a hysterectomy compared to women who had never been pregnant. Women who expressed any preference for English were twice as likely (odds ratio 2.050) to have had a hysterectomy than were those who responded that they exclusively preferred Spanish. Age, higher levels of education, and higher economic status also increased the risk of hysterectomy. In contrast, reproductive history, marital status, prior tubal ligation, generation of immigration, and health insurance did not have substantial effects on the risk of hysterectomy. This study suggests that, in the future, the effect of language preference should not be overlooked when considering risk factors for hysterectomy.

Oral health and use of dental services among Hispanics

OBJECTIVES

This study examined factors related to oral health and dental service use among Mexican-Americans, Cuban-Americans, and Puerto Ricans from the Hispanic Health and Nutrition Examination Survey, 1982-84 (HHANES).

METHODS

Categorical measures of oral health were created: (1) perceived oral health status, (2) evaluated oral health status, (3) decayed permanent teeth, (4) teeth missing due to caries, (5) total permanent teeth present, and (6) periodontal classification. The effects of acculturation, education, dental insurance, and perceived condition of teeth and gums on dental service use in the past two and five years were examined using logistic regression. All analyses were performed separately for each of the three samples using SAS-callable SUDDAN.

RESULTS

Dental insurance and education were the most important factors in determining use of dental cleanings and use of dental care. For Mexican-Americans, Cuban-Americans, and Puerto Ricans, acculturation was a factor in determining use of dental care in the past five years.

CONCLUSIONS

While dental insurance and education appear to be the most important factors for determining both use of dental cleaning services and use of dental care in all three samples, acculturation also had some impact for determining use of dental care.

Nonresponse in follow-back surveys of ethnic minority groups: an analysis of the Puerto Rican Maternal and Infant Health Study

OBJECTIVES

This study documents the levels and sources of nonresponse in the first large-scale maternal-infant health survey administered to representative samples of Puerto Rican mothers on both the U.S. mainland and the island of Puerto Rico.

METHODS

The data source is the Puerto Rican Maternal and Infant Health Study, which was administered to a vital records-based sample of 2763 mothers of infants. An additional 805 women were nonrespondents. Nonresponse is examined as a function of several characteristics measured from vital records using logistic regression.

RESULTS

The response rate for this survey compares favorably to response rates for similar surveys. Although nonresponse is not associated with most characteristics measured from vital records, it is higher among mainland residents and mothers of infants who died. The absence of significant associations is due to opposite relationships between several covariates and the failure to locate and refusal. For example, nonresponse in the birth sample is not associated with migration, despite the difficulty of locating migrants. The lower likelihood of locating migrants is offset by their willingness to participate.

CONCLUSIONS

Selectivity due to nonresponse is minimal. Nevertheless, researchers who design "binational" surveys should be aware of setting-specific circumstances that affect the ability to locate sampled individuals and secure their cooperation.

The impact of language barriers on the health care of Latinos in the United States: a review of the literature and guidelines for practice

Although Spanish was the primary language of an estimated 11 % of adults in the year 2000, the U.S. health care system is largely geared toward serving English speakers. A systematic review was conducted of studies published in biomedical journals from 1990 to 2000 examining language barriers in health care for Latino populations. Aspects of the problem examined were access to health care, quality of care, and health status/health outcomes. Five (55%) of the nine studies examining access to care found a significant adverse effect of language; three (33%) found mixed or weak evidence that language affected access. Six (86%) of the seven studies evaluating quality of care found a significant detrimental effect of language barriers. Two of the three studies examining health status or outcomes found language to be a risk factor for adverse outcomes. Evidence was mixed as to the level of importance attributable to language when access to care is considered; however, non-English-speaking status was a marker of a population at risk for decreased access. Solid evidence showed that language barriers can adversely affect quality of care. Health care practitioners are recommended to devise an effective strategy to bridge language barriers in their setting. National laws and policies are discussed; practical guidelines and resources for providing language access in health care are provided. This article is intended to supply basic knowledge for providers and institutions in devising effective strategies for bridging the language barrier.

Uncorrected binocular distance visual impairment in U.S. Hispanic children and adolescents

PURPOSE

To assess and compare uncorrected binocular distance visual impairment rates in U.S. Hispanic children and adolescents.

METHODS

Data from the Hispanic Health and Nutrition Examination Survey, 1982-1984, were analyzed for 6-19 year-old Cuban-Americans (n = 317), Mexican-Americans (n = 2519), and Puerto Ricans (n = 988). Visual acuity was assessed using Sloan Letters or Landolt Rings.

RESULTS

Prevalence rates of uncorrected binocular distance visual impairment (20/30 or worse) were 15.5%, 14.9%, and 23.6% for Cuban-Americans, Mexican-Americans, and Puerto Ricans, respectively. After adjusting for age and gender, the differences between Puerto Ricans and both Cuban-Americans and Mexican-Americans were significant (p < 0.05). Children 6-12 years of age had lower visual impairment rates than 13-19 year-old adolescents. Girls had higher age-adjusted visual impairment rates than boys; these gender differences were statistically significant among Mexican-Americans (OR = 1.6, 95% CI = 1.1, 2.2) and Puerto Ricans (OR = 1.7, 95% CI = 1.2, 2.4).

CONCLUSIONS

Among Hispanics, Puerto Rican children and adolescents have the highest prevalence rate of uncorrected binocular distance visual impairment; older age and female gender are associated with higher rates of uncorrected visual impairment.

Prevalence of usual-corrected distance visual acuity impairment in Hispanic and non-Hispanic children and adolescents

Data from the Hispanic Health and Nutrition Examination Survey and the National Health and Nutrition Examination Survey I were analysed to determine the prevalence of visual acuity impairment among US Hispanics and non-Hispanics aged 6-19 years. The prevalence of 20/30 or worse distance visual acuity with usual or habitual correction ranged from 10.8% in non-Hispanic whites to 19.1% in Puerto Ricans. Puerto Rican boys aged 13-19 years had significantly greater rates of moderate or greater impairment (20/70 or worse) than 6-12-year-old Puerto Rican boys (5.7% vs. 0.7%). The prevalence of visual impairment was generally greater in girls than in boys. Assessment and comparison of refractive error and eye disease prevalence rates are necessary in future studies to determine factors influencing prevalence of visual acuity impairment in children.

Acculturation and disordered eating patterns among Mexican American women

OBJECTIVE

This quantitative study examined the relationship between acculturation and disordered eating patterns among different generations of Mexican American women.

METHOD

Participants included 139 Mexican American women (mean age = 29.1) drawn from local undergraduate courses and community agencies. The posttest-only design included a demographic measure, Acculturation Rating Scale for Mexican Americans (ARSMA), and the Eating Attitudes Test (EAT-26).

RESULTS

Of the five generations studied, second-generation women endorsed the most disordered eating patterns and the highest degrees of concurrent acculturation. Moreover, there was a significant, positive correlation between acculturation and Factor III of the EAT which highlights control of eating and perceived pressure from others to gain weight. Participants scoring beyond the EAT cut-off score endorsed bulimic symptoms.

DISCUSSION

Differing intergenerational ideals regarding weight may create special strains for second-generation Mexican American women. Criteria for disordered eating in a population previously not considered at risk should be further assessed and clinicians should be careful not to underdiagnose among this group.

Current Depression, Lifetime History of Depression, and Visual Acuity in Hispanic Adults

This study used data from the Hispanic Health and Nutrition Examination Survey to examine associations between bilateral visual acuity and depression among Cuban American, Mexican American, and Puerto Rican adults. Among Mexican Americans, the odds of current depression were significantly higher for those with moderate and greater impairment distance acuity (20/80 or worse). Among Cuban Americans, the odds of lifetime history of major depressive disorder were significantly higher for those with a distance visual acuity worse than 20/50. There were no significant associations between either past or current depression and impaired visual acuity in Puerto Ricans. These findings provide only limited support for the hypothesis that odds of past and current depression are greater in Hispanics with impaired visual acuity than in Hispanics who are fully sighted.

Sociodemographic correlates of visual acuity impairment in Hispanic children and adolescents

Sociodemographic correlates of visual impairment were examined in 6- to 19-year-old Hispanic children and adolescents using data from the Hispanic Health and Nutrition Examination Survey. Mexican American and Puerto Rican children whose parents had 0 to 6 years of education were more likely to remain visually impaired even when tested with their glasses or contact lenses, if any (i.e., with usual correction) than children whose parents reported 12 to 17 years of education. Mexican Americans residing below versus at or above the poverty line were more likely to remain visually impaired even with the usual correction. Mexican Americans enrolled in the Medicaid program or who were without health insurance were more likely to remain visually impaired than Mexican Americans with private health insurance. When tested without glasses or contact lenses, Cuban Americans and Mexican Americans born outside of the mainland United States had lower rates of visual impairment compared to those born in the United States; however, children in this latter group were more likely to remain visually impaired with usual correction than U.S.-born Mexican Americans. These findings suggest that Hispanic children from economically disadvantaged households and those born outside the United States may not be receiving optimal eye care that could improve visual function.

Changes in the smoking behavior of elderly Mexican Americans in the Southwest from 1982-1984 to 1993-1994

OBJECTIVES

The aim of this work was to examine changes in the smoking behavior of elderly Mexican Americans in the southwestern United States from the early 1980s to the early 1990s.

METHODS

Data from the 1993-1994 Hispanic EPESE study (n = 2,809) on persons ages 65 to 74 and 75 to 84 residing in the five southwestern states were compared with data from the 1982-1984 Hispanic HANES study (n = 753, persons ages 55 to 74), which included a Mexican American sample from the same five southwestern states.

RESULTS

Rates of current smoking in 1993-1994 for persons ages 65 to 74 were approximately half the rates for persons of the same age a decade earlier. Smoking rates for persons ages 75 to 84 in 1993-1994 were significantly lower than rates for persons ages 65 to 74 a decade earlier. Finally, rates for persons ages 65 to 74 in 1993-1994 were significantly lower than those for persons ages 55 to 64 in 1982-1984.

CONCLUSIONS

Although some of the declines in smoking in recent years represent aging effects (including declines due to greater mortality among smokers), the much lower rates for same-age people (65 to 74) over the 10-year period are more significant in that they represent cohort differences. It appears that the broader public health message that is causing the general population to quit smoking is reaching the elderly Mexican American population of the Southwest.

Acculturation and breast cancer screening among Hispanic women in New York City

OBJECTIVES

This study investigated whether acculturation was associated with the receipt of clinical breast examinations and mammograms among Colombian, Ecuadorian, Dominican, and Puerto Rican women aged 18 to 74 years in New York City in 1992.

METHODS

A bilingual, targeted, random-digit-dialed telephone survey was conducted among 908 Hispanic women from a population-based quota sample. Outcome measures included ever and recent use of clinical breast examinations and mammograms. Multivariate logistic regression models were used to assess the effect of acculturation on screening use.

RESULTS

When demographic, socioeconomic, and health system characteristics and cancer attitudes and beliefs were controlled for, women who were more acculturated had significantly higher odds of ever and recently receiving a clinical breast examination (P < or = .01) and of ever (P < or = .01) and recently (P < or = .05) receiving a mammogram than did less acculturated women. For all screening measures, there was a linear increase in the adjusted probability of being screened as a function of acculturation.

CONCLUSIONS

Neighborhood and health system interventions to increase screening among Hispanic women should target the less acculturated.

Diabetes and hearing impairment in Mexican American adults: a population-based study

Reports on the relationship between diabetes and hearing loss have been controversial. The present study examined this relationship in 1,740 Mexican American adults using data from the Hispanic Health and Nutrition Examination Survey. Hearing threshold levels were obtained for each participant at the following frequencies: 500, 1000, 2000, and 4000 Hertz (Hz). The thresholds from the worse hearing ear were used in the analyses. Diabetes and insulin use were assessed by self-report. The mean crude hearing thresholds in diabetics were significantly higher than in non-diabetics at each of the four frequencies. However, after adjustment for age, gender, and socioeconomic status, diabetics had a significantly higher mean threshold than non-diabetics only at 500 Hz (mean difference +/- SE: 2.8 +/- 1.2, p = 0.04). Diabetics who were not using insulin had significantly higher thresholds than those who were using insulin at 2000 (mean difference +/- SE: 5.6 +/- 2.6, p = 0.03) and 4000 Hz (7.7 +/- 3.3, p = 0.02). Also, at 4000 Hz, insulin users had a significantly lower mean threshold than non-diabetics (mean difference +/- SE: -4.9 +/- 1.6, p = 0.02). Our data suggest that associations between diabetes and decreased hearing acuity in the higher frequencies are present only amongst diabetic Mexican-Americans who do not use insulin.

Prevalence of unilateral hearing loss in children: the National Health and Nutrition Examination Survey II and the Hispanic Health and Nutrition Examination Survey

We compared population-based prevalence rates of unilateral hearing loss among African-American, Cuban-American, Mexican-American, Puerto Rican, and non-Hispanic White children 6 to 19 yr of age. The prevalence (per thousand) of overall hearing loss (average decibel HTL >30) ranged from 6.4 in Mexican-Americans to 12.3 in Cuban-Americans. The prevalence of moderate to profound unilateral hearing loss (average decibel HTL >50) ranged from 0.0 in Cuban-Americans to 5.2 in Puerto Ricans. No statistically significant age or gender differences were found within any of the ethnic groups. Among these five ethnic groups, it is estimated that approximately 391,000 school-aged children in the United States have unilateral hearing loss.
