Education-based differences in alcohol health literacy in Germany.

Alcohol health literacy is critical for informed consumer decision making but has yet received limited attention in public health research. We therefore seek to measure alcohol health literacy and its educational distribution in Germany. In this cross-sectional study, we developed and applied a brief nine-item questionnaire on alcohol health literacy in an adult convenience sample (n = 391; February to April 2023). The association of educational attainment with 'insufficient' alcohol health literacy was tested in adjusted logistic regression models. Insufficient alcohol health literacy was recorded in 47.8% of men and 41.1% of women in our sample. While most respondents correctly identified common misconceptions and wrong beliefs about alcohol and were able to specify low-risk drinking limits for women and women during pregnancy, only few correctly identified all alcohol-related health conditions, especially respiratory and infectious diseases. Respondents with low education were 1.35 (risk ratio [RR], 95% confidence interval 1.09-1.50, p = 0.014) times more likely to have been classified as having insufficient alcohol health literacy than high-educated respondents. There was no statistically significant difference between respondents with medium versus high education (RR = 1.22, 95% confidence interval 0.99-1.43, p = 0.060). Educational gaps in alcohol health literacy question a policy rationale that is fundamentally based on the premise of informed consumer choice. Strategies to raise alcohol health literacy must ensure that they reach all population groups, for instance, by providing health warning labels on alcohol containers.

Controlling for polygenic genetic confounding in epidemiologic association studies

Epidemiologic associations estimated from observational data are often confounded by genetics due to pervasive pleiotropy among complex traits. Many studies either neglect genetic confounding altogether or rely on adjusting for polygenic scores (PGS) in regression analysis. In this study, we unveil that the commonly employed PGS approach is inadequate for removing genetic confounding due to measurement error and model misspecification. To tackle this challenge, we introduce PENGUIN, a principled framework for polygenic genetic confounding control based on variance component estimation. In addition, we present extensions of this approach that can estimate genetically unconfounded associations using GWAS summary statistics alone as input and between multiple generations of study samples. Through simulations, we demonstrate superior statistical properties of PENGUIN compared to the existing approaches. Applying our method to multiple population cohorts, we reveal and remove substantial genetic confounding in the associations of educational attainment with various complex traits and between parental and offspring education. Our results show that PENGUIN is an effective solution for genetic confounding control in observational data analysis with broad applications in future epidemiologic association studies.

Associations of educational attainment with Sepsis mediated by metabolism traits and smoking: a Mendelian randomization study.

Sepsis constitutes a significant global healthcare burden. Studies suggest a correlation between educational attainment and the likelihood of developing sepsis. Our goal was to utilize Mendelian randomization (MR) in order to examine the causal connection between educational achievement (EA) and sepsis, while measuring the mediating impacts of adjustable variables. We collected statistical data summarizing educational achievement (EA), mediators, and sepsis from genome-wide association studies (GWAS). Employing a two-sample Mendelian randomization (MR) approach, we calculated the causal impact of education on sepsis. Following this, we performed multivariable MR analyses to assess the mediation proportions of various mediators, including body mass index (BMI), smoking, omega-3 fatty acids, and apolipoprotein A-I(ApoA-I). Genetic prediction of 1-SD (4.2 years) increase in educational attainment (EA) was negatively correlated with sepsis risk (OR = 0.83, 95% CI 0.71 to 0.96). Among the four identified mediators, ranked proportionally, they including BMI (38.8%), smoking (36.5%), ApoA-I (6.3%) and omega-3 (3.7%). These findings remained robust across a variety of sensitivity analyses. The findings of this study provided evidence for the potential preventive impact of EA on sepsis, which may be influenced by factors including and metabolic traits and smoking. Enhancing interventions targeting these factors may contribute to reducing the burden of sepsis.

Causal effects of educational attainment on temporomandibular disorders and the mediating pathways: A Mendelian randomization study.

As one of the most important indicators of socioeconomic status, educational attainment (EA) exhibits a strong association with temporomandibular disorders (TMDs). Despite this link, there is a lack of evidence regarding the causal role of EA in either facilitating or preventing TMDs. This study aimed to investigate the causal effect of education on TMDs and explore potential mediating pathways. Utilizing summary statistics from genome-wide association studies on years of schooling (N = 766 345) and TMDs (N = 211 023), we conducted Mendelian randomization (MR) to assess the overall effect of education. Additionally, a two-step MR approach was employed to evaluate 30 potential mediators and calculate the mediation proportions in the association. Comprehensive sensitivity analyses were used to verify the robustness, heterogeneity, and pleiotropy. Univariable MR analyses revealed a causal effect of lower EA on an increased risk of TMDs (OR: 0.53, 95% CI: 0.43-0.66, p < .001). Five out of 30 modifiable factors were identified as causal mediators in the associations of EA with TMDs, including feeling nervous (mediation proportion: 11.6%), feeling tense (10.2%), depression (9.6%), feeling worry (7.6%) and daily smoking (8.9%). Meanwhile, no pleiotropy was detected in the analyses (p > .05). Our findings supported that higher EA has a protective effect on the onset of TMDs, with partial mediation by psychological disorders and daily smoking. Interventions on these factors thus have the potential of substantially reducing the burden of TMDs attributed to low education.

Association of educational attainment with hypertension and type-2 diabetes: A Mendelian randomization study

BACKGROUNDDue to the long time interval between exposure and outcome, it is difficult to infer the causal relationship between educational attainment (EA) and common chronic diseases. Therefore, we utilized Mendelian randomization (MR) to predict the causal relationships of EA with hypertension and type-2 diabetes (T2DM).METHODSA two-sample MR analysis was conducted using genome-wide association studies (GWASs) combined with inferential measurements. A GWAS meta-analysis including 1,131,881 European individuals was used to identify instruments for EA. Hypertension and T2DM data were obtained from a Finnish database.MR analyses were performed using inverse-variance weighted meta-analysis (IVW), weighted median regression, MR‒Egger regression, simple mode regression, weighted mode regression and the MR-Pleiotropy RESidual Sum and Outlier test. Sensitivity analyses were further performed using the leave-one-out method to test the robustness of our findings.RESULTSUsing the MR approach, our results showed that EA was significantly associated with a reduced risk of hypertension (OR = 0.63; P = 2.94 × 10−47; [95% CI: 0.59, 0.67]) and type-2 diabetes (OR = 0.59; P = 1.25 × 10−16; [95% CI: 0.52, 0.67]).CONCLUSIONSThis study showed that EA is causally linked to the risk of chronic diseases, including high blood pressure and T2DM.

Association of educational attainment with cancer mortality in a national cohort study of black and white adults: A mediation analysis

BackgroundLow educational attainment is associated with excess cancer mortality. However, the mechanisms driving this association remain unknown. MethodsUsing data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, we evaluated the associations of participant and parental/caregiver education with cancer mortality using Cox proportional hazards models, adjusting for socio-demographic characteristics and health conditions. We used principal components analysis to generate indices of measures representing the social determinants of health (SDOH) and health behaviors. We used structural equation modeling to determine if the association between educational attainment and cancer mortality was mediated by these domains. ResultsAmong 30,177 REGARDS participants included in this analysis, 3798 (12.6%) had less than a high school degree. In fully adjusted models, those without a high school education experienced about 50% greater risk of death than high school graduates and higher (White participants HR: 1.47; 95% CI: 1.23, 1.76 and Black HR: 1.54; 95% CI: 1.33, 1.79). There was evidence of a modest mediation effect for the association between education and cancer mortality by the SDOH domain score (White total effect HR: 1.25; 95% CI: 1.18, 1.33, indirect effect HR: 1.04; 95% CI: 1.03, 1.05, direct effect HR: 1.21; 95% CI: 1.14, 1.28 and Black total effect HR: 1.24; 95% CI: 1.18, 1.29, indirect effect HR: 1.04; 95% CI: 1.03, 1.05, direct effect HR: 1.19; 95% CI: 1.14, 1.24). There was no evidence of mediation by the health behaviors score. No significant associations were found for female caregiver/mother's or male caregiver/father's education (N = 13,209). ConclusionsIn conclusion, participant education was strongly associated with cancer mortality, and this association was partially mediated by the SDOH domain score.

Race or ethnicity and education in cardiac rehabilitation enrollment

BackgroundAlthough cardiac rehabilitation (CR) has established benefits for cardiovascular health, it remains significantly underutilized, with substantial differences in participation related to factors such as educational attainment (EA), race, and ethnicity. We studied a geographically and racially diverse cohort of insured individuals in a health claims database to (1) evaluate differences in CR participation by EA and race or ethnicity and (2) assess how EA modifies associations between race or ethnicity and CR participation. MethodsWe conducted a retrospective cohort study of individuals identified in Optum's de-identified Clinformatics® database between 1/1/2016 and 12/31/2019. Eligible individuals included those aged ≥18 years with a hospitalization for an incident CR-qualifying diagnosis. We calculated incidence rates of CR enrollment by EA and race or ethnicity, as well as associations of EA and race or ethnicity with CR enrollment, and evaluated interaction between EA and race or ethnicity with respect to CR participation. ResultsWe identified 171,297 individuals eligible for CR with a mean ± SD age of 70.4 ± 11.6 years; 37.4 % were female, and 68.3 % had >high school education. We observed a dose-response association between EA and rate of participation in CR. After adjustment, compared to White individuals, the odds of attending CR was 24 % lower for Asian individuals [95 % confidence interval (CI): 17 %, 30 %], 13 % lower for Black individuals (95 % CI: 9 %, 17 %), and 32 % lower for Hispanic individuals (95 % CI: 28 %, 35 %), all p < 0.0001. However, Black individuals with ≥bachelor's degree had a similar odds of CR enrollment as White individuals with ≥bachelor's degree (odds ratio 1.01, 95 % CI: 0.85, 1.20, p = 0.95). ConclusionsEA was positively associated with CR enrollment across racial and ethnic groups. Higher EA might partially attenuate racial and ethnic differences in CR participation, but significant disparities persist. Our findings support increased attention to individuals with limited education to improve CR enrollment.

Heterogenous trajectories in physical, mental and cognitive health among older Americans: Roles of genetics and life course contextual factors

We investigate the roles of genetic predispositions, childhood SES and adult educational attainment in shaping trajectories for three important components of the overall health of older adults -- BMI, depressive symptoms and cognition. We use the Health & Retirement Study (HRS) and group-based trajectory modeling (GBTM) to identify subgroups of people who share the same underlying trajectories ages 51–94 years. After identifying common underlying health trajectories, we use fractional multinomial logit models to estimate associations of (1) polygenic scores for BMI, depression, ever-smoked, education, cognition and subjective wellbeing, (2) childhood SES and (3) educational attainment with the probabilities of trajectory group memberships. While genetic predispositions do play a part in predicting trajectory group memberships, our results highlight the long arm of socioeconomic factors. Educational attainment is the most robust predictor—it predicts increased probabilities of belonging to trajectories with BMI in the normal range, low depressive symptoms and very-high initial cognition. Childhood circumstances are manifested in trajectories to a lesser extent, with childhood SES predicting higher likelihood of being on the low depressive symptoms and very-high initial cognition trajectories. We also find suggestive evidence that associations of educational attainment on the probabilities of being on trajectories with BMI in the normal range, low depressive symptoms and very-high initial cognition vary with genetic predispositions. Our results suggest that policies to increase educational attainment may improve population health by increasing the likelihood of belonging to “good” aging trajectories.

Association of educational attainment with esophageal cancer, Barrett's esophagus, and gastroesophageal reflux disease, and the mediating role of modifiable risk factors: A Mendelian randomization study.

Observational studies have reported that educational attainment has been related to the risk of esophageal cancer (EC) and its precancerous lesions. However, the causal relationship remains controversial. We aimed to apply the Mendelian randomization (MR) design to determine the causal associations between genetically predicted educational attainment and EC, Barrett's esophagus (BE), and gastroesophageal reflux disease (GERD), and to explore whether modifiable risk factors play a mediating role. Using summary statistics from genome-wide association studies (GWASs) based on European ancestry individuals of several years in education (EduYears, primary analysis, n = 293,723), college completion (College, secondary analysis, n = 95,427), EC (n = 420,531), BE (n = 361,194), and GERD (n = 420,531), genetic associations between two education phenotypes and EC, BE, and GERD were tested by two-sample MR analyses. Then, two-step MR mediation analyses were used to assess the proportion of the aforementioned association that might be mediated by body mass index (BMI), major depressive disorder (MDD), smoking, drinking, carbohydrates, fat, and protein intake. Genetically predicted EduYears was negatively associated with the risk of EC, BE, and GERD {odds ratio (OR), 0.64 [95% confidence interval (CI) 0.44-0.94], 0.86 (95% CI, 0.75-0.99), and 0.62 (95%CI, 0.58-0.67)}. EduYears was negatively associated with BMI, MDD, and smoking (range of OR: 0.76-0.84). There were positive associations between BMI, smoking with EC, BE, and GERD, as well as between MDD with GERD (range of OR: 1.08-1.50). For individual mediating effect, BMI and smoking mediated 15.75 and 14.15% of the EduYears-EC association and 15.46 and 16.85% of the EduYears-BE association. BMI, MDD, and smoking mediated 5.23, 4.98, and 4.49% of the EduYears-GERD association. For combined mediation, the aforementioned mediators explained 26.62, 28.38, and 11.48% of the effect of EduYears on EC, BE, and GERD. The mediating effects of drinking and dietary composition were not significant in the effect of education on EC, BE, and GERD. Our study supports that genetically predicted higher educational attainment has a protective effect on EC, BE, and GERD, and is partly mediated by reducing adiposity, smoking, and depression.

Can participation in learning abroad mobility support pro-European Union attitudes among youth?

The role of education in the development of pro-EU attitudes is often examined by focusing on the association of educational attainment and the development of pro-EU attitudes. However, student exchanges and youth mobility have also become pillars of the foundation of the European Higher Education Area, figuring out the Maastricht Treaty and the Bologna Declaration. Accordingly, based on a utilitarian approach, the current study investigates the role of participation in learning abroad mobility in the development of positive views on the EU. In doing so, Flash Eurobarometer 478 data was used and multinomial logistic regression analyses were performed by student and non-students groups of youth in the new (NMS) and old (EU15) member states. The findings show that the role of participation depends on the degree of positive views, and it makes a significant contribution to having Very Positive views on the EU among non-students in both national groups and students in the NMS. Findings also demonstrate that participation is more important than consideration in the development of Very Positive views. So, even if respondents could have already been supportive of the EU before participation, participation also takes their positive views on the EU to a higher level.

The Association of Patient Educational Attainment With Cardiac Rehabilitation Adherence and Health Outcomes.

Participating in cardiac rehabilitation (CR) after a cardiac event provides many clinical benefits. Patients of lower socioeconomic status (SES) are less likely to attend CR. It is unclear whether they attain similar clinical benefits as patients with higher SES. This study examines how educational attainment (one measure of SES) predicts both adherence to and improvements during CR. This was a prospective observational study of 1407 patients enrolled between January 2016 and December 2019 in a CR program located in Burlington, VT. Years of education, smoking status (self-reported and objectively measured), depression symptom level (Patient Health Questionnaire), self-reported physical function (Medical Outcomes Survey), level of fitness (peak metabolic equivalent, peak oxygen uptake, and handgrip strength), and body composition (body mass index and waist circumference) were obtained at entry to, and for a subset (n = 917), at exit from CR. Associations of educational attainment with baseline characteristics were examined using Kruskal-Wallis or Pearson's χ 2 tests as appropriate. Associations of educational attainment with improvements during CR were examined using analysis of covariance or logistic regression as appropriate. Educational attainment was significantly associated with most patient characteristics examined at intake and was a significant predictor of the number of CR sessions completed. Lower educational attainment was associated with less improvement in cardiorespiratory fitness, even when controlling for other variables. Patients with lower SES attend fewer sessions of CR than their higher SES counterparts and may not attain the same level of benefit from attending. Programs need to increase attendance within this population and consider program modifications that further support behavioral changes during CR.

Discordant associations of educational attainment with ASD and ADHD implicate a polygenic form of pleiotropy

Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are complex co-occurring neurodevelopmental conditions. Their genetic architectures reveal striking similarities but also differences, including strong, discordant polygenic associations with educational attainment (EA). To study genetic mechanisms that present as ASD-related positive and ADHD-related negative genetic correlations with EA, we carry out multivariable regression analyses using genome-wide summary statistics (N = 10,610–766,345). Our results show that EA-related genetic variation is shared across ASD and ADHD architectures, involving identical marker alleles. However, the polygenic association profile with EA, across shared marker alleles, is discordant for ASD versus ADHD risk, indicating independent effects. At the single-variant level, our results suggest either biological pleiotropy or co-localisation of different risk variants, implicating MIR19A/19B microRNA mechanisms. At the polygenic level, they point to a polygenic form of pleiotropy that contributes to the detectable genome-wide correlation between ASD and ADHD and is consistent with effect cancellation across EA-related regions.

The Contradictions of Liminal Legality: Economic Attainment and Civic Engagement of Central American Immigrants on Temporary Protected Status.

This study examines how Temporary Protected Status (TPS) may shape immigrants' integration trajectories. Building on core themes identified in the immigrant incorporation scholarship, it investigates whether associations of educational attainment with labor market outcomes and with civic participation, which are well established in the general population, hold for immigrants who live in the "liminal legality" of TPS. Conducted in 2016 in five U.S. metropolitan areas, the study is based on a unique survey of Salvadoran and Honduran TPS holders, the majority of immigrants on this status. The analyses find that TPS holders with higher levels of educational attainment do not derive commensurate significant occupational or earnings premiums from their education. In contrast, the analysis of the relationship between educational attainment and civic engagement detects a positive association: more educated TPS holders are more likely to be members of community organizations and to participate in voluntary community service, compared to their less educated counterparts. These findings illustrate the contradictions inherent to TPS as it may hinder certain aspects of immigrant integration but not others. This examination contributes to our understanding of the implications of immigrants' legal statuses and of immigration law and policy for key aspects of immigrant integration trajectories.

Association of Educational Attainment With Incidence of CKD in Young Adults

IntroductionChronic kidney disease (CKD) is greatly affected by social determinants of health. Whether low educational attainment is associated with incident CKD in young adults is unclear.MethodsWe evaluated the association of education with incident CKD in 3139 Coronary Artery Risk Development in Young Adults participants. We categorized education into low (high school and less), medium (college), and high (master’s and professional studies) groups. Incident CKD was defined as new development of estimated glomerular filtration rate (eGFR) <60 ml/min per 1.73 m2 or urine albumin to creatinine ratio (ACR) ≥30 mg/g. Change in eGFR over 20 years was a secondary outcome.ResultsAt baseline, mean age was 35.0 ± 3.6 years, 47% were Black, and 55% were women. Participants with lower educational attainment were less likely to have high income and health insurance and to engage in a healthy lifestyle. Over 20 years, 407 participants developed CKD (13%). Compared with individuals with low educational attainment, those with medium and high educational attainment had an unadjusted hazard ratios for CKD of 0.79 (95% confidence interval [CI] 0.65–0.97) and 0.44 (95% CI, 0.30–0.63), respectively. This association was no longer significant after adjusting for income, health insurance, lifestyle, and health status. Low educational attainment was significantly associated with a change in eGFR in crude and adjusted analyses, although the association was attenuated in the multivariable models (low: –0.83 [95% CI, –0.91 to –0.75], medium: –0.80 (95% CI, –0.95 to –0.64), and high: –0.70 (95% CI, –0.89 to –0.52) ml/min per 1.73 m2 per yr).ConclusionsHealth care access, lifestyle, and comorbid conditions likely help explain the association between low educational attainment and incident CKD in young adults.

Association of Educational Attainment With Adiposity, Type 2 Diabetes, and Coronary Artery Diseases: A Mendelian Randomization Study.

Background: Observational studies showed that educational attainment (EA) is associated with cardiometabolic diseases, but the long interval between exposure and outcome makes it difficult to infer causality. We herein used Mendelian randomization (MR) to examine the causal effects of EA on adiposity, type 2 diabetes (T2D), and coronary artery disease (CAD).Methods: A two-sample MR analysis was conducted using genome-wide association study (GWAS) summary statistics. Seventy-four instrumental variables (IVs) were used to determine the causal effect of EA on cardiometabolic diseases. Sensitivity analyses were also performed to detect the pleiotropy of the IVs.Results: Using the MR approach, we found that each additional year in EA is associated with a reduction in the body mass index (BMI) (β −0.17 [95% CI −0.23, −0.10], P = 8.85 × 10−7), a 39% reduction in the odds of having T2D (OR 0.61 [95% CI 0.50, 0.75], P = 1.16 × 10−6), and a 36% reduction in the odds of having CAD (OR 0.64 [95% CI 0.55, 0.75], P = 2.38 × 10−8) at the Bonferroni-adjusted level of significance.Conclusion: Our findings suggest a causal role of EA on the cardiometabolic diseases including adiposity, T2D, and CAD.

Association of Educational Attainment and Race/Ethnicity With Exposure to Tobacco Advertisement Among US Young Adults

Associations of educational attainment with improved health outcomes have been found to be weaker among racial/ethnic minority groups compared with those among the racial/ethnic majority group. Recent research has also documented higher than expected prevalence of smoking in highly educated African American and Hispanic adults. To compare the association of educational attainment with exposure to tobacco advertisements among racial/ethnic groups of US young adults. This cross-sectional study included data from 6700 young adults who participated in wave 1 of the Population Assessment of Tobacco and Health Study, a nationally representative survey of US adults in 2013. Educational attainment was classified as less than high school diploma, high school graduate, or college graduate. Analysis was conducted between September 20 and October 4, 2019. The independent variable was educational attainment (less than high school diploma, high school graduate, and college graduate). The dependent variable was any exposure to tobacco advertisements in the past 12 months. Race/ethnicity, age, sex, poverty status, unemployment, and region were the covariates. Binary logistic and Poisson regression were used to analyze the data. The study included 6700 participants (3366 [50.2%] men) between ages 18 and 24 years. Most participants were non-Hispanic (5257 participants [78.9%]) and white (5394 participants [80.5%]), while 1443 participants (21.5%) were Hispanic. Educational levels included 1167 participants (17.4%) with less than a high school diploma, 4812 participants (71.8%) who were high school graduates, and 4812 participants (10.8%) who were college graduates. A total of 4728 participants (70.6%) reported exposure to tobacco advertisements in the past 12 months. Exposure to tobacco advertising was reported by 383 participants (53.1%) who were college graduates, 3453 participants (71.8%) who were high school graduates, and 892 participants (76.4%) with less than high school educational attainment. In regression analysis, high school graduation (odds ratio, 0.79; 95% CI, 0.68-0.92) and college graduation (odds ratio, 0.46; 95% CI, 0.39-0.54) were associated with lower odds of exposure to tobacco advertisements compared with young adults with lower educational attainment. Compared with non-Hispanic participants, high school education had a weaker protective association for tobacco advertisement exposure among Hispanic participants (odds ratio, 1.44; 95% CI, 1.03-2.01; P = .03), suggesting that the association of high school graduation with lower exposure to tobacco advertisement is weaker among Hispanic young adults than non-Hispanic young adults. This study found that high school graduation had a weaker inverse association with tobacco advertisement exposure among Hispanic than non-Hispanic young adults. Future research should explore the role of targeted marketing strategies of the tobacco industry that largely advertise tobacco in areas with high concentrations of racial/ethnic minority groups. Future research should also evaluate the efficacy of more restrictive marketing policies on racial/ethnic disparities in tobacco use.

Different Associations of Socioeconomic Status on Protein Intake in the Korean Elderly Population: A Cross-Sectional Analysis of the Korea National Health and Nutrition Examination Survey.

Socioeconomic status affects food choices. This study examined the relationships between socioeconomic status (SES) and animal and plant protein intake in the Korean elderly population whose protein intake is insufficient. We used cross-sectional data from 3512 Koreans aged 60 years or older, who had participated in the Nutrition Survey of the 2013–14 Korea National Health and Nutrition Examination Survey (KNHANES). One day 24-h recall data was used to estimate the daily total, animal, and plant protein intake. Household income and educational attainment were assessed by trained interviewers. After making adjustment, household income was positively associated with animal protein intake with a statistical significance in females (p = 0.030) and with a marginal significance in males (p = 0.069). However, plant protein intake did not show any significant association. In both sexes, educational attainment was positively associated with animal protein intake (p = 0.007 for males, p = 0.001 for females). Association of educational attainment with plant protein intake was negative in males (p = 0.037) and non-significant in females. (p = 0.945). High SES was associated with higher total protein intake and animal protein intake in the Korean elderly. Health policies and nutrition education are needed to improve protein intake of the vulnerable Korean elderly with low SES.

Declining association with persistent gender asymmetric structure: patterns and trends in educational assortative marriage in Japan, 1950–1979

This paper investigates the patterns and trends of educational assortative marriage in Japan. Using data from the Employment Status Survey and the Comprehensive Survey of Living Conditions of the People on Health and Welfare, we investigated the trends of association between husbands’ and wives’ educational attainment (481,144 couples) by applying log-linear, log-multiplicative layer effects, and regression-type models. The analysis revealed that, in general, educational assortative marriage has decreased continuously. In terms of the log-odds ratios, the association of educational attainment between spouses for women born between 1975 and 1979 decreased by about 25%, in comparison with that of women born between 1950 and 1954. The regression-type models showed that the pattern of association was asymmetric while patterns of change were symmetric with respect to sex. We discuss what caused the decline in educational assortative marriage with a persistent gender asymmetric structure.

Association of Educational Attainment and Cardiovascular Risk in Hispanic Individuals

Hispanic individuals are the fastest growing ethnic group in the United States and face lower socioeconomic status compared with non-Hispanic white (NHW) individuals. However, Hispanic individuals tend to experience better health outcomes than expected, a phenomenon known as the Hispanic paradox. Little is known about how higher socioeconomic status is associated with Hispanic cardiovascular risk factor burden and outcomes. To determine cardiovascular risk and outcomes among highly educated Hispanic vs NHW individuals in a preventive medicine clinic. Retrospective cohort analysis of participants from the Cooper Center Longitudinal Study who underwent preventive medical examinations at the Cooper Clinic in Dallas, Texas, from October 1972 to November 2017. Analysis began April 2018. Ethnicity, self-defined as Hispanic or NHW. Prevalence of major metabolic risk factors and cardiorespiratory fitness were compared, as were changes among participants with at least 2 visits. Ethnic differences adjusted for age, examination year, and educational attainment were estimated using regression models. Age-matched comparisons of coronary artery calcium scores were performed. All-cause mortality was summarized using the Kaplan-Meier method. This study included 1351 Hispanic and 43 736 NHW participants aged 20 to 80 years, body mass index between 18.5 and 50.0, and were not missing key cardiometabolic or fitness variables. Both Hispanic and NHW participants had high educational attainment, with a mean of more than 15 years of total education. Hispanic women and men had a higher prevalence of metabolic syndrome (71 of 518 [13.1%] vs 1477 of 13 732 [10.8%] for women and 255 of 833 [30.6%] vs 7902 of 30 004 [26.3%] for men, respectively). Although Hispanic individuals were twice as likely to have diabetes, there was no difference in calculated 10-year atherosclerotic cardiovascular disease risk scores by ethnicity. Both Hispanic and NWH individuals experienced a statistically significant worsening in cardiometabolic parameters during follow-up, although this was not statistically significantly different between groups. In age-matched analyses, there were no significant differences in the prevalence of coronary artery calcium scores between Hispanic and NWH individuals. During a mean (SD) follow-up of 12.9 (7.5) years, there was no difference in mortality between Hispanic and NHW individuals. Hispanic and NHW men and women with high educational attainment had similar atherosclerotic cardiovascular disease risk, subclinical coronary atherosclerosis, and mortality during follow-up. These findings do not support the Hispanic paradox in a highly educated Hispanic population.

Does education attenuate the genetic risk of obesity? Evidence from U.K. Twins

More education is associated with a lower body mass index (BMI) and likelihood of being obese. Obesity and BMI also have a strong genetic basis. Given these observations, we investigate whether more education can reduce obesity by attenuating the underlying genetic risk of being obese, through gene-environment (GxE) interactions. We estimate associations between (i) education, (ii) a genetic risk score (GRS) and (iii) GxE interactions between education and the GRS through Ordinary least Squares (OLS) and twins fixed-effect regressions using data on female twins from the TwinsUK database. OLS estimates show that there are significant associations of education and genetics. Female twins with a university education are 14.3 percentage points less likely to be obese compared to twins with less than compulsory education, and a 1 standard deviation increase in the GRS increases the likelihood of being obese by 5.2 percentage points. The GxE interactions are statistically insignificant, suggesting that the marginal association of the GRS with obesity does not differ by educational attainment. When controlling for confounding through twins fixed-effects, we find a smaller role of genetics. The association of the GRS with obesity decreases to 0.040. Associations of educational attainment are substantially reduced and insignificant. GxE interactions also remain insignificant. Overall, we find little evidence of any GxE interactions.
