Prevalence and Predictors of Left Ventricular Diastolic Dysfunction in a Hispanic Patient Population

Minimal data exist on attributes of diastolic dysfunction in the Hispanic population. The purpose of this study was to evaluate the prevalence and predictors of diastolic dysfunction in a Hispanic patient population. We performed a retrospective review of 166 consecutive echocardiograms in a southwestern Texas Hospital that caters to a large Hispanic patient population. We identified all echocardiograms that met criteria for diastolic dysfunction and assessed baseline demographics and comorbidities in the cohort of Hispanic patients. A multivariate analysis was performed to identify the independent predictors of diastolic dysfunction. A total of 129 out of 166 patients (77.8%) were of Hispanic origin. Out of the 129 patients, 87 (67.4%) had some degree of diastolic dysfunction in this population suggesting a high prevalence in the study cohort. In the diastolic dysfunction group, the mean age was 64.5 ± 13.9, 37% were male and 63% female, 78% had diabetes, 85% had hypertension, and 49% had some degree of renal insufficiency (stages 3–5). A logistic multivariate analysis showed that diabetes was an independent predictor of diastolic dysfunction with odds ratio of 2.69 (95% confidence interval [CI], 1.06–6.28; p = 0.038). Similarly age (per year increase) and chronic kidney disease were independent predictors of diastolic dysfunction. We demonstrated that older age, presence of diabetes, and renal dysfunction are independent predictors of diastolic dysfunction in the Hispanic patient population. Strategies geared toward reducing diabetes and preventing renal dysfunction are likely to decrease prevalence of diastolic dysfunction and heart failure in this community.     

Acculturation and the prevalence of depression in older Mexican Americans: baseline results of the Sacramento Area Latino Study on Aging

OBJECTIVE: To determine the association between acculturation, immigration, and prevalence of depression in older Mexican Americans. DESIGN: Cross-sectional analysis from a cohort study. SETTING: Urban and rural counties of the Central Valley of Northern California. PARTICIPANTS: One thousand seven hundred and eighty-nine Latinos recruited from a population-based sample (85% Mexican Americans) with a mean age of 70.6 (range 60-100; standard deviation (SD) = 7.13); 58.2% were women. MEASUREMENTS: Depressive symptoms were assessed with the Center for Epidemiologic Studies--Depression scale (CES-D). Acculturation was measured with the Acculturation Rating Scale for Mexican Americans--II. Psychosocial, behavioral, and medical histories were also obtained. RESULTS: The prevalence of depression (CES-D > or = 16) was 25.4%. Women were at greater risk (32.0%) than men (16.3%; male/female odds ratio (OR) = 2.43, 95% confidence interval (CI) = 1.90-3.09). The prevalence of depression was higher among immigrants (30.4%, OR = 1.70, 95% CI = 1.36-2.13), bicultural participants (24.2%, OR = 1.66, 95% CI = 1.24-2.24), and less-acculturated participants (36.1%, OR = 2.95, 95% CI = 2.22-3.93) compared with U.S.-born (20.5%) and more-acculturated groups (16.1%). When adjustments for education, income, psychosocial, behavioral, and health-problem factors were made, the least-acculturated participants were at significantly higher risk of depression than highly acculturated Mexican Americans (OR = 1.56, 95% CI = 1.06-2.31). CONCLUSIONS: These findings are consistent with previously reported estimates of a higher prevalence of depression for older Mexican Americans than non-Hispanic Caucasians and African Americans and are the first to report the prevalence and risk of depression for older U.S.-born and immigrant Mexican Americans. The high prevalence of depression of the least acculturated group may be related to cultural barriers encountered by immigrants and less-acculturated older Mexican Americans and to poorer health status.     

A Path Analysis of Latino Parental,Teenager and Cultural Variables in Teenagers' Sexual Attitudes,Norms, Self-Efficacy,and Sexual Intentions

OBJECTIVE:

to test a theoretical model based on the Parent-Based Expansion of the Theory of Planned Behavior examining relation between selected parental, teenager and cultural variables and Latino teenagers'' intentions to engage in sexual behavior.

METHOD:

a cross-sectional correlational design based on a secondary data analysis of 130 Latino parent and teenager dyads.

RESULTS:

regression and path analysis procedures were used to test seven hypotheses and the results demonstrated partial support for the model. Parent familism and knowledge about sex were significantly associated with parents'' attitudes toward sexual communication with their teenagers. Parent Latino acculturation was negatively associated with parents'' self-efficacy toward sexual communication with their teenagers and positevely associated with parents'' subjective norms toward sexual communication with their teenagers. Teenager knowledge about sex was significantly associated with higher levels of teenagers'' attitudes and subjective norms about sexual communication with parents. Only the predictor of teenagers'' attitudes toward having sex in the next 3 months was significantly associated with teenagers'' intentions to have sex in the next 3 months.

CONCLUSION:

the results of this study provide important information to guide future research that can inform development of interventions to prevent risky teenager sexual behavior among Latinos.     

Enrollment in Hispanic Serving Institutions as a Moderator of the Relationship Between Drinking Norms and Quantity of Alcohol Use Among Hispanic College Students

Background: Hispanic college students represent a growing proportion of the college population. Studies have found that an individual's perception of the drinking of others is linked to one's own personal use and that college students frequently overestimate the drinking of their peers. The current study builds on previous college student drinking literature by examining the influence that attending a Hispanic-serving institution (HSI) has on the personal alcohol use and perception of peers’ drinking norms among Hispanic college students. Methods: This secondary data analysis utilized data from the American College Health Association's National College Health Assessment. Participants were self-identified Hispanics between the ages of 18 and 25 (N = 4336). Results: Results indicated that there was a significant interaction between attending an HSI and the perception of the number of drinks of a typical student. Specifically, the perception of others’ drinking was more strongly linked to personal drinking for students in non-Hispanic serving institutions. Conclusions: The protective effect of attending a Hispanic-serving institution may be related to a more culturally affirming college environment.     

Trends in Alcohol-Related Mortality among New Mexico's American Indians, Hispanics, and Non-Hispanic Whites

Reduction of alcohol-related mortality is a national goal for health promotion and disease prevention. We conducted this analysis to determine whether trends in New Mexico's Hispanics, non-Hispanic Whites, and American Indians were consistent with national trends in alcohol-related mortality, and whether differences in drinking patterns could account for racial and ethnic differences in rates. Age-adjusted, race-specific, and ethnic-specific alcohol-related mortality rates and 95% confidence intervals were calculated for 5-year periods for 1958–1991 using New Mexico vital statistics data. We estimated the prevalence of acute and chronic at-risk drinking behaviors and abstinence from data collected by the Behavioral Risk Factor Surveillance System (BRFSS) for the period 1986–1992. We found that alcohol-related mortality rates varied substantially by race, ethnicity, sex, age, and calendar period. American Indians had the highest rates for both sexes. Rates increased sharply from the period 1958–1962 until the late 1970s and the early 1980s, and then began to decrease rapidly. However, during the most recent decade, the rates have followed contrasting trends in the three ethnic and racial groups. Although rates have continued to decline among non-Hispanic Whites, rates for Hispanics and American Indians have not declined, and still remain substantially higher than rates during the 1958–1962 period. Differences in at-risk drinking behaviors reported to the BRFSS do not explain the contrast in race-specific and ethnic-specific mortality rates. Although progress has been made in reducing national per capita alcohol consumption and alcohol-related mortality, certain high-risk racial and ethnic groups may not be sharing in the progress.
