Cardiovascular health in Hispanics/Latinos: a reexamination of the Hispanic paradox

Racial and ethnic disparities in chronic disease risk in adolescence after prenatal polydrug exposure: Examination of the Hispanic paradox

Racial disparities exist in fetal development which in turn can influence growth and development of chronic disease later in life. The purpose of this study was to explore potential racial and ethnic differences in chronic disease risk factors throughout the pediatric years given prenatal exposure to substance use. Data from the Maternal Lifestyle Study cohort was used for this analysis. Urine toxicology confirmed maternal substance use (y/n) and offspring height, weight, and systolic blood pressure (SBP) data at 16 years was analyzed. Linear mixed effects modeling with an interaction term for adolescent race/ethnicity and maternal drug use assessed growth trajectories (body mass index (BMI) percentile) and cardiovascular disease risk factors (elevated SBP). Of the sample (n = 1,388 mother/infant dyads), 23% (n = 319) of mothers used three substances during pregnancy and 14% (n = 200) used four or five. Controlling for BMI, Hispanic adolescents prenatally exposed to any singular substance had 13 mmHg higher SBP at age 16 than their unexposed counterparts (95% Confidence Interval [CI]: 12.24, 14.01). Prenatal exposure to >1 substance significantly lowered SBP in Hispanic adolescents only. Results here showed that Hispanic adolescents exposed to singular substance are at higher risk of elevated SBP in adolescence, but SBP decreased when exposed to >1 substance. The Hispanic paradox may play a role; future studies should continue to explore this. Additionally, barriers to prenatal care for Hispanic women should be addressed in order to prevent substance use during pregnancy which can reduce chronic disease risk in offspring adolescence.

Unique Cardiovascular Disease Risk Factors in Hispanic Individuals

Purpose of Review

This review summarizes contemporary data on unique cardiovascular disease (CVD) risk factors in Hispanic individuals in the USA, and how addressing these factors is important in addressing health equity.

Recent Findings

Recent studies have shown high rates of traditional CVD risk factors in Hispanic individuals such as obesity, hypertension, diabetes, hyperlipidemia, and emerging CVD risk factors like hypertensive disorders of pregnancy, psychological stress, and occupational exposures. However, most studies fail to consider the significant heterogeneity in risk factor burden and outcomes in atherosclerotic CVD by Hispanic subgroup. Heart failure and rhythm disorders are less well studied in Hispanic adults, making risk assessment for these conditions difficult. High levels of CVD risk factors in Hispanic youth given an aging Hispanic population overall highlight the importance of risk mitigation among these individuals.

Summary

In brief, these data highlight the significant, unique burden of CVD risk among Hispanic individuals in the USA and predict a rising burden of disease among this growing and aging population. Future CVD research should focus on including robust, diverse Hispanic cohorts as well as specifically delineating results for disaggregated Hispanic groups across CVDs. This will allow for better risk assessment, prevention, and treatment decisions to promote health equity for Hispanic patients.

Diminished Health Returns of Educational Attainment Among Immigrant Adults in the United States

Objectives: Marginalization-related diminished returns (MDRs) refer to weaker health effects of educational attainment for socially marginalized groups compared to the socially privileged groups. Most of the existing literature on MDRs, however, has focused on marginalization due to race, ethnicity, and sexual orientation. Thus, very limited information exists on MDRs of educational attainment among immigrant populations in the United States. Aims: Building on the MDRs framework and using a nationally representative sample of US adults, we compared immigrant and native-born adults for the effects of educational attainment on psychological distress, self-rated health (SRH), and chronic diseases (CDs). Methods: The 2015 National Health Interview Survey (NHIS) has enrolled 33,672 individuals who were either immigrant (n = 6,225; 18.5%) or native born (n = 27,429; 81.5%). The independent variable (IV) was educational attainment, which was treated as a categorical variable. The dependent variables included psychological distress, SRH, and CDs, all of which were dichotomous variables. Age, gender, race, ethnicity, and region were confounders. Immigration (nativity status) was the moderator. Results: Higher educational attainment was associated with lower odds of psychological distress, poor SRH, and CDs. However, immigration showed a significant statistical interaction with college graduation on all outcomes, which were suggestive of smaller protective effects of college graduation on psychological distress, poor SRH, and CDs for immigrant than native-born adults. Conclusions: In the US, the associations between educational attainment and psychological distress, SRH, and CDs are all weaker for immigrant than native-born adults. To prevent health disparities, it is essential to decompose health inequalities that are due to low educational attainment from those that are due to diminished returns of educational attainment (i.e., MDRs). There is a need to help highly educated immigrant adults secure positive health outcomes, similar to their native-born counterparts. Such changes may require bold and innovative economic, public, and social policies that help immigrant adults to more effectively mobilize their educational attainment to secure tangible outcomes. Elimination of health disparities in the US requires efforts that go beyond equalizing access to education.

Does education modify the effect of ethnicity in the expression of ideal cardiovascular health? The Baptist Health South Florida Employee Study

BACKGROUND

Despite the progress made to decrease risk factors for cardiovascular diseases, disparities still exist. We examined how education and ethnicity interact to determine disparities in cardiovascular health (CVH) as defined by the American Heart Association.

HYPOTHESIS

Education modifies the effect of ethnicity on CVH.

METHODS

Individual CVH metrics (smoking, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose) were defined as ideal, intermediate, or poor. Combined scores were categorized as inadequate, average, or optimal CVH. Education was categorized as postgraduate, college, some college, and high school or less; ethnicity was categorized as white, Hispanic, black, and other. Main and interactive associations between education, ethnicity, and the measures of CVH were calculated with multinomial logistic regression.

RESULTS

Of 9056 study participants, 74% were women, and mean age was 43 (±12) years. Over half were Hispanic, and two-thirds had at least a college education. With postgraduate education category as the reference, participants with less than a college education were less likely to achieve ideal status for most of the individual CVH metrics, and also less likely to achieve 6 to 7 ideal metrics, and optimal CVH scores. In most of the educational categories, Hispanic participants had the highest proportion with optimal CVH scores and 6 to 7 ideal metrics, whereas black participants had the lowest proportion. However, there were no statistically significant interactions of education and ethnicity for ideal CVH measures.

CONCLUSIONS

Higher educational attainment had variable associations with achieved levels of ideal CVH across race/ethnic groups. Interventions to improve CVH should be tailored to meet the needs of target communities.
