Anomaly in the education-health gradient: Biomarker profiles among adults with subbaccalaureate attainment levels

Student Debt and Cardiovascular Disease Risk Among U.S. Adults in Early Mid-Life

INTRODUCTION

Student loan debt has become common for young adults in the U.S. and is correlated with poor physical and mental health. It is unclear how the accumulation or repayment of student debt is associated with longer-term cardiovascular risks and chronic inflammation.

METHODS

Nationally representative data collected between 1994 and 2018 from >4,000 participants of a U.S. cohort study were analyzed in 2021 to assess the associations among change in student debt between young adulthood and early mid-life, 30-year Framingham cardiovascular disease risk scores, and C-reactive protein levels.

RESULTS

Ordinary least squares regression revealed higher cardiovascular disease and C-reactive protein risks among those in households who became indebted or were consistently in debt between young adulthood and early mid-life than among those in households who were either never in debt or repaid their loans. This pattern persisted after adjustments for degree completion, socioeconomic measures, and other sources of debt.

CONCLUSIONS

These findings provide a benchmark for widening health inequalities among a cohort bearing more student debt than any other in U.S.

HISTORY

As student debt accumulates, within-cohort disparities in cardiovascular disease and related morbidities may undermine the health benefits of postsecondary education.

Lifecourse Educational Trajectories and Hypertension in Midlife: An Application of Sequence Analysis

BACKGROUND

Higher educational attainment predicts lower hypertension. Yet, associations between nontraditional educational trajectories (eg, interrupted degree programs) and hypertension are less well understood, particularly among structurally marginalized groups who are more likely to experience these non-traditional trajectories.

METHODS

In National Longitudinal Survey of Youth 1979 cohort data (N = 6 317), we used sequence and cluster analyses to identify groups of similar educational sequences-characterized by timing and type of terminal credential-that participants followed from age 14-48 years. Using logistic regression, we estimated associations between the resulting 10 educational sequences and hypertension at age 50. We evaluated effect modification by individual-level indicators of structural marginalization (race, gender, race and gender, and childhood socioeconomic status [cSES]).

RESULTS

Compared to terminal high school (HS) diploma completed at traditional age, terminal GED (OR: 1.32; 95%CI: 1.04, 1.66) or Associate degree after

CONCLUSIONS

Both type and timing to terminal credential matter for hypertension but effects may vary by experiences of structural marginalization. Documenting the nuanced ways in which complex educational trajectories are associated with health could elucidate underlying mechanisms and inform systems-level interventions for health equity.

The relationship between postsecondary education and adult health behaviors

Nearly 80% of American adults between the ages of 33-44 have at least some postsecondary education, which ranges from vocational training to a doctorate or professional degree. However, in education-health studies, postsecondary credentials are often grouped into a limited number of categories. This is an important omission as it obscures differentiations between the various types of postsecondary credentials. This study provides the first comprehensive analysis of disparities in health behaviors across detailed levels of postsecondary education. Data comes from Wave 5 of the 2018 National Longitudinal Study of Adolescent to Adult Health (Add Health). A covariance-weighting technique is used to produce behavioral index scores that identify the full spectrum of health behaviors influenced by postsecondary educational attainment. Estimates are initially produced in aggregate for the total sample population, with interaction models subsequently being used to test differences across gender and race/ethnicity population subgroups. The aggregate results indicate that adults with at least a bachelor's degree exhibit healthier lifestyles; however, no difference is observed among adults with lower-level postsecondary credentials, compared to high school graduates. Women experience steeper gradients at higher levels of postsecondary education, compared to men. Both White and Hispanic American adults exhibit comparable health lifestyles across levels of postsecondary education; however, Black Americans were found to experience no returns except at the doctorate or professional degree level. These findings have important implications particularly as adults in their thirties and forties continue to exhibit troubling health and mortality trends.

Educational Attainment and Psychological Distress Among Working-Age Adults in the United States

This study builds on a growing body of literature analyzing the education-health gradient across detailed educational categories, which documents that US working-age adults who attended college but did not earn a bachelor's degree report equal or worse health than adults with a high school diploma. This is known as the "anomaly" in the education-health gradient. The purpose of this study is to test whether this pattern extends to measures of serious psychological distress (SPD) and individual symptoms by using data from the National Health Interview Survey (NHIS, 1997-2018) and a series of logistic regression models. We find that the anomaly in the education-health gradient is present for a summary measure of SPD as well as for five of the six symptoms that make up this measure. The exception was reporting feeling sad most or all the time during the last month, where adults with "some college" were found to have lower odds than those with a high school diploma. Further stratified analysis by sex revealed that this result for feeling sad was driven by women. In terms of associate degrees, our models show that adults with a vocational/technical associate degree have statically similar odds of SPD and reporting four out of six symptoms (exceptions were feeling hopeless and sadness), while those with an academic associate degree have significantly lower odds in all outcomes. The robustness of the models used is supported by an extensive sensitivity analysis. Overall, we find evidence of the anomaly in the education-health gradient in SPD and individual symptoms of psychological distress at the sub-baccalaureate level, adding to previous studies that document the anomaly in markers of physiological dysregulation, health conditions, vision problems, functional limitations, and pain.

The Relationship Between Education and Pain Among Adults Aged 30-49 in the United States

Pain is a major health problem among U.S. adults. Surprisingly little, however, is known about educational disparities in pain, especially among the nonelderly. In this study, we analyze disparities in pain across levels of educational attainment. Using data from the 2010 to 2017 National Health Interview Survey among adults aged 30 to 49 (N = 74,051), we estimate logistic regression models of pain prevalence using a dichotomous summary pain index and its 5 constituent pain sites (low back, joint, neck, headache/migraine, and facial/jaw). We find a significant and steep pain gradient: greater levels of educational attainment are associated with less pain, with 2 important exceptions. First, adults with a high-school equivalency diploma (GED) and those with "some college" have significantly higher pain levels than high school graduates despite having an equivalent or higher attainment, respectively. Second, the education-pain gradient is absent for Hispanic adults. After taking into account important covariates including employment, economic resources, health behaviors, physical health conditions, and psychological wellbeing, educational disparities in pain are no longer statistically significant except for the GED and "some college" categories, which still show significantly higher pain levels than high school graduates. We thus document the overall education-pain gradient in most younger U.S. adult populations, and identify groups where pain is higher than expected (certain educational categories) or lower than expected (eg, less-educated Hispanics). Understanding the causes of these anomalous findings could clarify factors shaping pain prevalence and disparities therein. PERSPECTIVE: Over 50% of U.S. adults age 30 to 49 report pain. Overall, more educated Americans report substantially less pain than the less educated. However, adults with a GED and "some college" report more pain than other groups. Understanding the causes could help illuminate the mechanisms through which social factors influence pain.

Educational differences in mortality associated with central obesity: Decomposing the contribution of risk and prevalence

Thousands of preventable deaths are attributed to obesity in the United States. However, the harmfulness of obesity varies across the population; individuals' education determines access to healthful resources and exposure to competing risks, dampening/amplifying obesity-associated mortality risk. Using restricted U.S. National Health and Nutrition Examination Survey data (N = 40,058; 1988-2015), this study estimates educational differences in mortality attributable to central obesity (waist-to-height ratio ≥0.5) - a dangerous form of abdominal adiposity. Over 30% of excess deaths are attributable to central obesity among college-educated adults, compared to 1-10% among their less-educated counterparts. This difference is larger for cardiometabolic-related mortality, as central obesity may explain 60-70% of excess deaths among college-educated adults. Decomposition analyses show differences are driven by greater obesity-associated risk among college-educated adults, rather than prevalence. Policies targeting health disparities should recognize central obesity as a key risk among highly-educated adults, but only one of many encountered by those with less education.

Prostate Cancer Screening in Middle-Aged and Older American Men: Combined Effects of Ethnicity and Years of Schooling

BACKGROUND

Prostate cancer screening is more commonly utilized by highly educated people. As shown by marginalization-related diminished returns (MDRs), the effects of socioeconomic status (SES) such as education on the health outcomes are considerably smaller for ethnic minorities than for Whites. The role of MDRs as a source of ethnic health disparities is, however, still unknown.

OBJECTIVES

The current study had two aims: first, to explore the association between years of schooling and having taken a prostate-specific antigen (PSA) test among men in the US, and second, to explore ethnic differences in this association.

METHODS

This study was a secondary analysis of data from the National Health Interview Survey (NHIS-2015). The data of 5,053 men aged 55 years or older who were either Latino, non-Latino, African-American, or White were analyzed. Years of schooling was the independent variable. The dependent variable was taking a PSA test sometime during one's lifetime. Age, region, and employment were the control variables. Ethnicity was the focal moderating variable. Binary logistic regression was used for data analysis.

RESULTS

A higher number of years of schooling was associated with higher odds of having taken a PSA test, net of all confounders. Ethnicity showed a significant statistical interaction with years of schooling on having taken a PSA test. This interaction was suggestive of a smaller slope for Latino men than non-Latino men. White and African American men did not show differential effects of years of schooling on having taken a PSA test.

CONCLUSION

Similar to the MDRs patterns in other domains, non-Latino White men show more health gain from their years of schooling than Latino men. Highly educated Latino men still need programs to encourage their use of prostate cancer screening.

Combined Effects of Race and Educational Attainment on Physician Visits Over 24 Years in a National Sample of Middle-Aged and Older Americans

Background

The literature on Minorities' Diminished Returns (MDRs) have shown worse than expected health of the members of racial and ethnic minority groups particularly Blacks. Theoretically, this effect can be in part due to weaker effects of educational attainment on preventive care and disease management in highly educated racial and ethnic minorities.

Objectives

The current study explored the racial and ethnic differences in the effect of baseline educational attainment on % adherance to the routine physician visits among middle-aged and older adults in the US.

Methods

This is a prospective study with 24 years of follow up. The Health and Retirement Study (HRS: 1992-2016) included 10 880 middle-aged and older adults who were Hispanic, non-Hispanic, Black or White. The independent variable was educational attainment. The dependent variable was adherance to the routine physician visits (%). Age, gender, marital status, income, health behaviors (smoking and drinking) and health (depression, self-rated health, and chronic diseases) were the covariates. Race and ethnicity were the focal moderators. Linear regression was used for data analysis.

Results

Overall, higher educational attainment was associated with higher % of adherance to the routine physician visits over the course of follow-up, net of all confounders. Race showed a significant statistical interaction with educational attainment suggesting of a smaller effect of high education attainment on % adherance to the routine physician visits for Black than White middle-aged and older adults. A similar interaction could not be found for the comparison of Hispanic and non-Hispanic middle-aged and older adults.

Conclusion

Educational attainment is associated with a larger increase in preventive and disease management doctor visits for White than Black middle-aged and older adults. This is a missed opportunity to improve the health of highly educated middle-aged and older adults. It is not race/ethnicity or class that shapes health behaviors but race/ethnicity and class that shape people's pro-health behaviors. At least some of the racial health disparities is not due to low SES but diminished returns of SES.

Diminished Returns of Educational Attainment on Heart Disease among Black Americans

Background

Socioeconomic Status (SES) indicators, such as educational attainment, are social determinants of heart disease. Marginalization related Diminished Returns (MDRs) refer to smaller health benefits of high SES for racial and ethnic minorities compared to the majority group. It is still unknown, however, if MDRs also apply to the effects of education on heart disease.

Purpose

Using a nationally representative sample, we explored racial/ethnic variation in the link between educational attainment and heart disease among American adults.

Methods

We analyzed data (n=25,659) from a nationally representative survey of American adults in 2013. The first wave of the Population Assessment of Tobacco and Health - Adult (PATH-Adult) study was used. The independent variable was education (college graduate, high school graduate, less than a high school diploma). The dependent variable was any heart disease. Age and gender were the covariates. Race, as well as ethnicity, were the moderators. Logistic regressions were used to analyze the data.

Results

Individuals with higher educational attainment had lower odds of heart disease. Race and ethnicity showed statistically significant interactions with education, suggesting that the protective effect of higher education on reducing odds of heart disease was smaller for Hispanic and Black people than for non-Hispanic and White individuals.

Conclusion

Education reduces the risk of heart disease better among non-Hispanic Whites than for Hispanics and Blacks. Therefore, we may expect a disproportionately higher than expected risk of heart disease in Hispanics and Blacks with high educational attainment. Future research should test if the presence of high levels of environmental and behavioral risk factors contribute to the high risk of heart disease in highly educated Black and Hispanic Americans. Policymakers should not reduce health inequalities to just gaps in SES because disparities are present across SES levels, with high SES Blacks and Hispanics remaining at risk of health problems.

Educational Attainment Better Increases the Chance of Breast Physical Exam for Non-Hispanic Than Hispanic American Women: National Health Interview Survey

Background

The Minorities' Diminished Returns (MDRs) theory suggests that the health effect of educational attainment is considerably smaller for members of racial and ethnic minority groups than for Whites.

Objective

The current study explored the racial and ethnic differences in the association between educational attainment and breast physical exam (BPE) among women in the U.S.

Methods

The National Health Interview Survey (NHIS 2015) included 12 510 women who were Hispanic or non-Hispanic Black or White people. The independent variable was the level of educational attainment. The dependent variable was lifetime BPE. Age, region, marital status, and employment were the covariates. Race and ethnicity were the focal moderators. Logistic regressions were used for data analysis.

Results

Overall, higher educational attainment was associated with higher odds of BPE, net of all confounders (odds ratio [OR] = 1.11, 95% CI = 1.09-1.13). Ethnicity showed a significant statistical interaction with educational attainment on BPE (OR = 0.96, 95% CI = 0.93-1.00), which was suggestive of a smaller effect of high education attainment on BPE for Hispanic than non-Hispanic women. The same interaction could not be found for the comparison of White and Black women (OR = 0.98, 95% CI =0.94-1.02).

Conclusion

In line with other domains, non-Hispanic White women show a larger amount of health gain from their educational attainment than Hispanic women. It is not ethnicity or class but ethnicity and class that shapes how people engage in pro-health behaviors. This result may help hospitals and healthcare systems to better reduce health disparities in their target populations.

Race, Ethnicity, Socioeconomic Status, and Chronic Lung Disease in the U.S

BACKGROUND

Higher socioeconomic status (SES) indicators such as educational attainment and income reduce the risk of chronic lung diseases (CLDs) such as Chronic Obstructive Pulmonary Disease (COPD), emphysema, chronic bronchitis, and asthma. Marginalization-related Diminished Returns (MDRs) refer to smaller health benefits of high SES for marginalized populations such as racial and ethnic minorities compared to the socially privileged groups such as non-Hispanic Whites. It is still unknown, however, if MDRs also apply to the effects of education and income on CLDs.

PURPOSE

Using a nationally representative sample, the current study explored racial and ethnic variation in the associations between educational attainment and income and CLDs among American adults.

METHODS

In this study, we analyzed data (n = 25,659) from a nationally representative survey of American adults in 2013 and 2014. Wave one of the Population Assessment of Tobacco and Health (PATH)-Adult study was used. The independent variables were educational attainment (less than high school = 1, high school graduate = 2, and college graduate =3) and income (living out of poverty =1, living in poverty = 0). The dependent variable was any CLDs (i.e., COPD, emphysema, chronic bronchitis, and asthma). Age, gender, employment, and region were the covariates. Race and ethnicity were the moderators. Logistic regressions were fitted to analyze the data.

RESULTS

Individuals with higher educational attainment and those with higher income (who lived out of poverty) had lower odds of CLDs. Race and ethnicity showed statistically significant interactions with educational attainment and income, suggesting that the protective effects of high education and income on reducing odds of CLDs were smaller for Blacks and Hispanics than for non-Hispanic Whites.

CONCLUSIONS

Education and income better reduce the risk of CLDs among Whites than Hispanics and Blacks. That means we should expect disproportionately higher than expected risk of CLDs in Hispanics and Blacks with high SES. Future research should test if high levels of environmental risk factors contribute to the high risk of CLDs in high income and highly educated Black and Hispanic Americans. Policy makers should not reduce health inequalities to SES gaps because disparities sustain across SES levels, with high SES Blacks and Hispanics remaining at risk of health problems.

Being Married Increases Life Expectancy of White but Not Black Americans

Objective: The positive effect of high socioeconomic position (SEP) on health is well established. According Minorities' Diminished Returns (MDRs) theory, however, the SEP-health link is smaller for Blacks compared to Whites. Using a 25-year follow up data of a national sample, this study tested racial differences in the effects of marital status on life expectancy among American adults. Materials and methods: The data of Americans' Changing Lives (ACL, 1986 - 2011) were used. The ACL is a nationally representative longitudinal cohort study followed 3,361 White or Blacks adults from 1986 to 2011. The predictor of interest was marital status in 1986. Confounders included demographic factors (age and gender), SEP (education and employment), health behaviors (drinking, smoking, and physical activity), and health status (depressive symptoms, chronic disease, and self-rated health) all measured at baseline. Race was the moderator variable. All-cause mortality was the main dependent variable (outcome). Cox proportional hazard modeling was applied for data analysis. Results: In the overall sample, individuals who were married at baseline had a lower risk of mortality during the 25 years of follow up. Race altered the effect of marital status on life expectancy, indicating smaller protective effect for Blacks relative to Whites. Race -specific Cox regression models showed an association between marital status and life expectancy for White but not Black Americans. Conclusion: In line with the MDRs theory, the health gain that follows marital status is diminished for Black Americans compared to White Americans. Only equalizing SEP across racial groups may not be adequate for eliminating racial/ethnic health inequalities. Policies should go beyond SEP and reduce societal and structural barriers that disproportionately hinder Blacks from translating their SEP indicators to desirable health outcomes.

Educational Attainment and Exercise Frequency in American Women; Blacks' Diminished Returns

BACKGROUND

Minorities' Diminished Returns (MDRs) refer to smaller protects health effects of socioeconomic status (SES) indicators for Blacks and other minority groups than Whites.

OBJECTIVES

The current study aimed to explore Black- White differences in the association between educational attainment and exercise frequency among women in the US.

METHODS

For the current study, we used the National Survey of American Life's (NSAL) data which included 3,175 women who were either White (n = 876) or Black (n = 2,299). The independent variable was educational attainment. The dependent variable was exercise frequency. Age, region, household income, financial distress, marital status, unemployment, and depression were the covariates. Race was the focal moderator. Linear regression was applied for data analysis.

RESULTS

In the overall sample of women, high educational attainment was associated with higher exercise frequency (b = 0.07, 95% CI = 0.02-0.12). Race and educational attainment showed a significant interaction (b = -0.09, 95% CI = -0.19-0.00), suggestive of a smaller effect of education attainment on exercise frequency for Black women than White women. In race specific models, high educational attainment was associated with higher exercise frequency for White (b = 0.12, 95% CI =0.04-0.20) but not Black (b = 0.03, 95% CI = -0.03-0.08) women.

CONCLUSION

In line with the past research on MDRs, White women gain more health from their educational attainment than Black women. It is not race or class but race and class that shape the health behaviors of American women.

The Relationship Between Education and Health: Reducing Disparities Through a Contextual Approach

Adults with higher educational attainment live healthier and longer lives compared with their less educated peers. The disparities are large and widening. We posit that understanding the educational and macrolevel contexts in which this association occurs is key to reducing health disparities and improving population health. In this article, we briefly review and critically assess the current state of research on the relationship between education and health in the United States. We then outline three directions for further research: We extend the conceptualization of education beyond attainment and demonstrate the centrality of the schooling process to health; we highlight the dual role of education as a driver of opportunity but also as a reproducer of inequality; and we explain the central role of specific historical sociopolitical contexts in which the education-health association is embedded. Findings from this research agenda can inform policies and effective interventions to reduce health disparities and improve health for all Americans.

Graduating into Lower Risk: Chlamydia and Trichomonas Prevalence among Community College Students and Graduates

BACKGROUND

Community colleges enable youth from economically disadvantaged and minority populations to access college and may enable social mobility including improved health outcomes. However, educational health disparities studies rarely assess the health outcomes for community college graduates.

METHODS

Chlamydia and trichomonas prevalence were assessed with nucleic acid based tests in a nationally representative sample of 6233 high school graduates (ages 18-25) from five educational levels: young adults without post-secondary credentials who were not enrolled in college, community college students, 4-year college students, associate's degree, and bachelor's degree. To reduce confounding between educational attainment and STI status, we used full matching to balance on 22 measures of demographics, socioeconomic status, educational factors, and sexual risk-taking. Estimates of associations between educational attainment and STI status were obtained from multivariate regression in the full (n=6233) and matched (n=1655) samples.

RESULTS

Four-year college students (adjusted incidence rate ratio (IRR) = 0.41, 95% CI [0.27, 0.61], p<0.001), associate's degree holders (IRR = 0.38 [0.15, 0.98], p=0.05), and bachelor's degree holders (IRR = 0.45 [0.23, 0.90], p=0.02) were less than half as likely to test positive for chlamydia than non-college-enrolled high school graduates in multivariate regression. After full matching, associate's degree holders were also less likely to test positive for chlamydia (IRR 0.46 (0.23, 0.85), p=0.03) than community college students. Four-year college students (IRR = 0.52 [0.24, 1.12], p=0.10) and associate's degree holders (IRR = 0.34 [0.12, 0.97], p=0.04) were half as likely to test positive for trichomonas than nonstudents/non-graduates in multivariate regression but did not differ after full matching.

CONCLUSIONS

Community college students come from populations with greater health risks than 4-year college students, but community college graduation may reduce the likelihood of chlamydia infection. STI interventions can meet the needs of young adults who access college through community college by partnering with community college health clinics to encourage continued STI prevention, testing, and treatment after the intervention ends. Public health studies that use inclusive educational attainment measures that incorporate sub-baccalaureate credentials will better capture health disparities.

Gender and Health Behavior Clustering among U.S. Young Adults

U.S. trends in population health suggest alarming disparities among young adults, who are less healthy across most measureable domains than their counterparts in other high-income countries; these international comparisons are particularly troubling for women. To deepen our understanding of gender disparities in health and underlying behavioral contributions, we document gender-specific clusters of health behavior among U.S. young adults using nationally representative data from the National Longitudinal Study of Adolescent to Adult Health. We find high levels of poor health behavior, but especially among men; 40 percent of men clustered into a group characterized by unhealthy behavior (e.g., poor diet, no exercise, substance use), compared to only 22 percent of women. Additionally, women tend to age out of unhealthy behaviors in young adulthood more than men. Further, we uncover gender differences in the extent to which sociodemographic position and adolescent contexts inform health behavior clustering. For example, college education was more protective for men, whereas marital status was equally protective across gender. Parental drinking mattered for health behavior clustering among men, whereas peer drinking mattered for clustering among women. We discuss these results in the context of declining female advantage in U.S. health and changing young adult social and health contexts.
