Abstract
Introduction Cerebellum cortex fractional anisotropy is a proxy of the integrity of the cerebellum cortex. However, less is known about how it is shaped by race and socioeconomic status (SES) indicators such as parental education and household income. Purpose In a national sample of American pre-adolescents, this study had two aims: to test the effects of two SES indicators, namely parental education and household income, on cerebellum cortex fractional anisotropy, and to explore racial differences in these effects. Methods Using data from the Adolescent Brain Cognitive Development (ABCD) study, we analyzed the diffusion Magnetic Resonance Imaging (dMRI) data of 9565, 9-10-year-old pre-adolescents. The main outcomes were cerebellum cortex fractional anisotropy separately calculated for right and left hemispheres using dMRI. The independent variables were parental education and household income; both treated as categorical variables. Age, sex, ethnicity, and family marital status were the covariates. Race was the moderator. To analyze the data, we used mixed-effects regression models without and with interaction terms. We controlled for propensity score and MRI device. Results High parental education and household income were associated with lower right and left cerebellum cortex fractional anisotropy. In the pooled sample, we found significant interactions between race and parental education and household income, suggesting that the effects of parental education and household income on the right and left cerebellum cortex fractional anisotropy are all significantly larger for White than for Black pre-adolescents. Conclusions The effects of SES indicators, namely parental education and household income, on pre-adolescents' cerebellum cortex microstructure and integrity are weaker in Black than in White families. This finding is in line with the Marginalization-related Diminished Returns (MDRs), defined as weaker effects of SES indicators for Blacks and other racial and minority groups than for Whites.

Iveson MH, Deary IJ. Early-life predictors of retirement decisions and post-retirement health. SSM Popul Health 2019; 8:100430.

Abstract
It remains unclear whether retirement circumstances are associated with better or worse post-retirement health. This is partly due to confounding between measures of retirement circumstances and a tendency to account only for covariates around retirement age. The present study examined the contributions of both retirement age and retirement type, independently, to post-retirement health around age 77 years. It also examined whether these contributions remain once earlier life-course factors – social class, cognitive ability and education – were accounted for. Our sample was 742 Scottish people who took part in the Scottish Mental Survey 1947. In a path model including life-course predictors, retirement type (reason), but not age, significantly predicted post-retirement health, with ill-health retirement associated with poorer physical (β = 0.455, 95% CI [0.313, 0.597], p < 0.001) and mental health (β = 0.339, 95% CI [0.191, 0.486], p < 0.001), and redundancy retirement associated with poorer physical health only (β = 0.200, 95% CI [0.069, 0.331], p = 0.004). Of the life-course predictors, higher adult social class was associated with later retirement (β = 0.115, 95% CI [0.034, 0.196], p = 0.006) and higher childhood cognitive ability was associated with increased odds of voluntary retirement (OR = 1.054, 95% CI [1.005, 1.105], p = 0.032), but no indirect contribution to health (mediated by retirement circumstances) was significant. At the same time, higher childhood cognitive ability directly predicted better post-retirement physical health (β = -0.110, 95% CI [-0.216, -0.004], p = 0.041), independently of retirement circumstances. This study demonstrates the importance of considering retirement circumstances beyond age, and of accounting for confounding between retirement circumstances and earlier life-course factors. Retirement type, not age, predicted post-retirement physical and mental health. Higher childhood cognitive ability predicted better post-retirement physical health. Retirement circumstances did not mediate associations with post-retirement health.

Abstract
BACKGROUND Childhood socioeconomic status (SES) is related to risk for cardiovascular disease in adulthood, perhaps, in part, due to associations with inflammatory and hemostasis processes. We tested the hypotheses that childhood SES is related to C-reactive protein (CRP), fibrinogen, factor VIIc, and plasminogen activator inhibitor-1 (PAI-1) in midlife women and that the associations are mediated by adult SES and/or adult body mass index (BMI). METHODS Using data from the prospective Study of Women's Health Across the Nation, we classified 1067 black and white women into 3 multidimensional childhood SES groups based on latent class analysis. Biological measures were assessed across 7 years along with covariates and mediators and analyzed by mixed regression models, followed by tests for mediation. RESULTS Compared with women raised in high SES families, those from the lowest SES families had higher levels of CRP (b [standard error] = 0.37 [0.11]), PAI-1 (b = 0.23 [0.07]) factor VIIc (b = 0.05 [0.02]), and fibrinogen (b = 11.06 [4.89]), after adjustment for ethnicity, site, age, ratings of health between ages 11 and 18 years, visit, smoking status, menopausal status, stroke or heart attack, medications, and hormone use. Introduction of adult SES and BMI into the models reduced the childhood SES associations to nonsignificance for all four measures. Indirect mediation was apparent for adult education and BMI for CRP, and BMI for PAI-1. CONCLUSIONS Women raised in lower SES families had elevated markers of inflammation and hemostasis, in part, due to elevated BMI and education in adulthood.

Abstract
Background:
Coronary artery disease (CAD) is associated with cognitive decrements and risk of later dementia, but it is not known if shared genetic factors underlie this association. We tested whether polygenic risk for CAD was associated with cognitive ability in community-dwelling cohorts of middle-aged and older adults.
Methods:
Individuals from Generation Scotland: Scottish Family Health Study (GS:SFHS,
N
= 9865) and from the Lothian Birth Cohorts of 1921 (LBC1921,
N
= 517) and 1936 (LBC1936,
N
= 1005) provided cognitive data and genome-wide genotype data. Polygenic risk profile scores for CAD were calculated for all of the cohorts using the largest available genome-wide association studies (GWAS) data set, the CARDIoGRAM consortium (22 233 cases and 64 762 controls). Polygenic risk profile scores for CAD were then tested for their association with cognitive abilities in the presence and absence of manifest cardiovascular disease.
Results:
A meta-analysis of all three cohorts showed a negative association between CAD polygenic risk and fluid cognitive ability (β = −0.022,
P
= 0.016), verbal intelligence (β = −0.024,
P
= 0.011) and memory (β = −0.021,
P
= 0.028).
Conclusions:
Increased polygenic risk for CAD is associated with lower cognitive ability in older adults. Common genetic variants may underlie some of the association between age-related cognitive decrements and the risk for CAD.

Abstract
OBJECTIVE To investigate a life-span health-behavior mechanism relating childhood personality to adult clinical health. METHODS Childhood Big Five personality traits at mean age 10, adult Big Five personality traits, adult clinically assessed dysregulation at mean age 51 (a summary of dysregulated blood glucose, blood pressure, and lipids), and a retrospective, cumulative measure of life-span health-damaging behavior (lifetime smoking, physical inactivity, and body mass index from age 20) were assessed in the Hawaii Personality and Health Cohort (N = 759). Structural equation modeling was used to test the conceptual model with direct and indirect paths from a childhood Conscientiousness factor to an adult Conscientiousness factor, life-span health-damaging behaviors, educational attainment, adult cognitive ability, and adult clinical health. RESULTS For both men and women, childhood Conscientiousness influenced health-damaging behaviors through educational attainment, and life-span health-damaging behaviors predicted dysregulation. Childhood Conscientiousness predicted adult Conscientiousness, which did not predict any other variables in the model. For men, childhood Conscientiousness predicted dysregulation through educational attainment and health-damaging behaviors. For women, childhood Conscientiousness predicted dysregulation through educational attainment and adult cognitive ability. CONCLUSIONS Assessing cumulative life-span health behaviors is a novel approach to the study of health-behavior mechanisms. Childhood Conscientiousness appears to influence health assessed more than 40 years later through complex processes involving educational attainment, cognitive ability, and the accumulated effects of health behaviors, but not adult Conscientiousness.

Abstract
OBJECTIVE The association between personality traits and mortality might differ as a function of socioeconomic status (SES). Our aim was to evaluate the all-cause, cardiovascular disease (CVD), and cancer mortality risk associated with neuroticism or extraversion and their interactions with SES in a representative sample of the UK adult population. METHODS A total of 5450 participants (2505 men) from the Health and Lifestyle Survey completed the Eysenck Personality Inventory at baseline and were monitored for vital status over 25 years. SES was defined as a latent variable comprising occupational social class, educational attainment, and income. RESULTS A significant neuroticism-by-SES-by-sex interaction (p = .04) for CVD mortality revealed a neuroticism-by-SES interaction specific to women. Compared to women with average SES, those with both high neuroticism and low SES were at an increased risk for CVD mortality (hazard ratio = 2.02, 95% confidence interval = 1.45-2.80), whereas those with high neuroticism and high SES combined were at a decreased risk for CVD mortality (hazard ratio = 0.61, 95% confidence interval = 0.38-0.97, p for interaction = 0.003). The interaction term was not explained by health behaviors (10% attenuation) and physiological variables (11% attenuation). This interaction was not observed for all-cause and cancer mortality risks or among men for CVD mortality. CONCLUSIONS High neuroticism is a risk factor for cardiovascular mortality in women with low SES, whereas in women with higher SES, it is protective. Further research is needed to replicate this finding and identify the mechanisms behind the modifying effect of SES on neuroticism.

Abstract
Physical activity may promote cognitive health in older adults. Popular media play an important role in preventive health communication. This study examined articles discussing associations between physical activity and cognitive health in top-circulating magazines targeting older adults. 42,753 pages of magazines published from 2006 to 2008 were reviewed; 26 articles met inclusion criteria. Explanations regarding the link between physical activity and cognitive health were provided in 57.7% of articles. These explanations were generally consistent with empirical evidence; however, few articles included empirical evidence. Physical activity recommendations were presented in 80.8% of articles; a wide range was recommended (90–300 min of physical activity per wk). Socioeconomic status and education level were not mentioned in the text. Results suggest an opportunity for greater coverage regarding the role of physical activity in promoting cognitive health in popular media. Magazine content would benefit from including more empirical evidence, culturally sensitive content, and physical activity recommendations that are consistent with U.S. guidelines.
