Project description:OBJECTIVE:To evaluate a possible physiological mechanism underlying links between low childhood socioeconomic status (SES) and poor adult health by (a) testing whether childhood SES is prospectively related to cardiovascular responses to laboratory stress in adulthood, and (b) by determining whether psychological resources buffer cardiovascular reactivity and promote better recovery from stress. METHOD:Participants (n = 246; 55% Black; mean age = 32 years) were from a population-based sample of men in Pittsburgh, PA. Childhood SES was measured through the Hollingshead index (parental education and occupation) across 10 waves between the ages of 6 and 16. In adulthood, cardiovascular measures, including systolic and diastolic blood pressure (SBP, DBP), heart rate (HR), and high-frequency heart rate variability (HF-HRV), were taken during and following standardized laboratory psychological stressors. Participants completed measures of optimism, purpose in life, self-esteem, positive affect, and self-mastery, which were combined into a psychological resource factor. RESULTS:Lower childhood SES predicted higher HR and SBP at recovery, independent of age, race, body mass index, current smoking, task demand, and current SES. Psychological resources moderated the association between childhood SES and SBP. Lower childhood SES predicted SBP recovery only among men with fewer psychological resources. CONCLUSIONS:Psychological resources may buffer the relation between low childhood SES and cardiovascular recovery from stress. This buffering may improve adult health to the extent that cardiovascular recovery contributes to the risk of low childhood SES for subsequent disease. (PsycINFO Database Record

Project description:ObjectiveThe current study examined race differences in how childhood socioeconomic status (SES) predicted midlife inflammation. It also tested psychological resources (purpose in life, optimism, and conscientiousness) as moderators of the association between childhood SES and inflammation among Black and White adults.MethodData came from the biomarker subsamples of the Midlife in the United States Core and Refresher studies (n = 1,578 White and n = 395 Black participants). Childhood SES was operationalized as a composite of parental education, perceived financial status, and welfare status. Outcomes included circulating IL-6 and CRP.ResultsChildhood SES did not predict IL-6 or CRP among Black or White adults in fully adjusted models. Among Black adults with low optimism, lower childhood SES predicted higher IL-6 and CRP. Among Black adults with low purpose in life, lower childhood SES predicted higher CRP (but not IL-6). Conscientiousness did not moderate childhood SES-inflammation associations among Black adults. Among White adults with low conscientiousness or low optimism, lower childhood SES predicted higher IL-6 (but not CRP). Purpose in life did not moderate associations among White adults. Effect sizes were small (≤1% variance explained) and comparable to effects of clinical risk factors in this sample (e.g., age, chronic conditions).ConclusionsRace differences in the childhood SES and inflammation association were not apparent. Childhood SES was linked to inflammation more strongly among those with fewer psychological resources across both racial groups. Psychological resources may be important moderators of inflammation in the context of early life SES disadvantage. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Project description:American Heart Association (AHA) developed a new metric to evaluate ideal cardiovascular health based on optimal levels of 7 cardiovascular risk factors and health behaviors. We evaluated the relationships of parenting characteristics and academic achievement in adolescence in relation to ideal cardiovascular health in midlife men.We measured cardiovascular risk factors in 171 Black and 136 White men and their ideal cardiovascular health score was constructed based on AHA guidelines. When the participants were 13-16 years old, annual measures of parent-child communication, positive relationship, parental monitoring, family cohesion, boys' involvement in family activities, and academic achievement were recorded and averaged.Confirmatory factor analysis of adolescent parenting measures revealed a single Parenting Composite. Multiple linear regressions showed a significant Race by Parenting Composite interaction term, ? = -.19, p = .03; better parenting was significantly related to more ideal cardiovascular health in Blacks only, ? = -.23, p = .004, which remained after adjustments for adolescent and adult socioeconomic status (SES). Academic achievement was related to ideal cardiovascular health, ? = -.13, but was no longer significant after controls for adult SES. Adult SES was a strong correlate of ideal cardiovascular health in Black and White men.Black men exposed to positive parenting during adolescence had more ideal cardiovascular health based on AHA guidelines. Improving academic achievement in adolescence may indirectly benefit adult cardiovascular health through improving adult SES. This is the first study of adolescent family predictors of the extent of ideal cardiovascular health. (PsycINFO Database Record

Project description:Childhood socioeconomic status (SES) is inversely associated with adult weight in high income countries. Whether the influence of childhood SES on adult weight is best described using a critical period model or an accumulation of risk model is not yet settled. This research tests whether childhood SES is associated with adult BMI and likelihood of obesity independent of adult socioeconomic status and neighborhood characteristics. Data on individual childhood and adult characteristics come from the Health and Retirement Study (N = 13,545). Data on neighborhood characteristics come from the 2000 Decennial Census and American Community Survey (2005-2009). In the fully adjusted models, perceived financial hardship before the age of sixteen and having a father who was unemployed are associated with higher BMI among males and, among females, paternal education remains associated with adult BMI. However, childhood SES is not associated with likelihood of obesity after fully adjusting for adult SES and neighborhood characteristics, suggesting that the direct effects of early childhood SES on BMI are small relative to the other factors associated with obesity in adulthood.

Project description:Social and economic disadvantage are hypothesized to increase the risk of disease and death via accelerated biological aging. Given that US blacks are socially and economically disadvantaged relative to whites, health disparities scholars expected that blacks would have shorter telomere length-a biomarker of cell aging-than whites. Yet the majority of studies have found that blacks have longer telomere length than whites. Using data from the National Health and Nutrition Examination Survey (n = 3,761; 28.3% non-Hispanic black, 71.7% non-Hispanic white), we found that leukocyte telomere length was 4.00% (95% CI: 1.12%, 6.87%) longer among blacks compared to whites in the full sample, but differences were greatest among those with lower SES (5.66%; 95% CI: 0.10%, 10.32%), intermediate among those with middle SES (4.14%; 95% CI: 0.05%, 8.24%), and smallest among those with higher SES (2.33%; 95% CI: -3.02%, 7.67%). These results challenge purely genetic explanations for race differences in telomere length and point to a potential social-environmental cause of longer telomere length in US blacks.

Project description:PURPOSE:To assess whether the higher prevalence of childhood trauma exposure but lower prevalence of alcohol use in Black vs. White adolescent girls reflects a lower magnitude of association between trauma and alcohol use initiation in Black girls; and additionally, whether low socioeconomic status (SES) and neighborhood factors account in part for the link between trauma and early alcohol use. METHODS:Data were drawn from annual interviews conducted with an urban sample of girls and their primary caregivers from ages 5-8 (baseline) through age 17 (n?=?2068, 57.7% Black, 42.3% White). Cox proportional hazards regression analyses using race and childhood trauma to predict alcohol use initiation were conducted in two stages, with SES and neighborhood factors added in the second stage. RESULTS:Childhood trauma was more prevalent (29.0 vs. 17.5%) and alcohol use initiation less prevalent (37.7 vs. 54.4%) in Black vs. White girls, but we found no evidence for differences in liability conferred by trauma. However, significant changes in hazards ratios (HRs) from the unadjusted to adjusted models were observed for Black race (HR?=?0.57, CI 0.50-0.65 to HR?=?0.66, CI 0.54-0.80) and childhood trauma (HR?=?1.70, CI 1.46-1.99 to HR?=?1.34, CI 1.05-1.71). CONCLUSIONS:Findings indicate that childhood trauma is an equally potent risk factor for early drinking onset for Black and White girls; the risk for early alcohol use in Black girls who have experienced traumatic events should not be underestimated. Results further indicate that low SES and neighborhood factors contribute to the associations of childhood trauma and race with alcohol use initiation.

Project description:Study objectives: This study examines the influence of individual and neighbourhood socioeconomic status (SES) on mortality among black, Mexican-American, and white women and men in the US. The authors had three study objectives. Firstly, they examined mortality rates by both individual level SES (measured by income, education, and occupational/employment status) and neighbourhood level SES (index of neighbourhood income/wealth, educational attainment, occupational status, and employment status). Secondly, they examined whether neighbourhood SES was associated with mortality after controlling for individual SES. Thirdly, they calculated the population attributable risk to estimate the reduction in mortality rates if all women and men lived in the highest SES neighbourhoods.DesignNational Health Interview Survey (1987-1994), linked with 1990 census tract (neighbourhood proxy) and mortality data through 1997.Setting/participantsNationally representative sample of 59 935 black, 19 201 Mexican-American, and 344 432 white men and women (six gender and racial/ethnic groups), aged 25-64 at interview.Main resultsMortality rates for all six gender and racial/ethnic groups were two to four times higher for those with the lowest incomes (lowest quartile) who lived in the lowest SES neighbourhoods (lowest tertile) compared with those with the highest incomes who lived in the highest SES neighbourhoods. For the six groups, the age adjusted mortality risk associated with living in the lowest SES neighbourhoods ranged from 1.43 to 1.61. The mortality risk decreased but remained significant (p values <.05) after adjusting for each of the three individual measures of SES, with the exception of Mexican-American women. Furthermore, the mortality risk associated with living in the lowest SES neighbourhoods remained significant after simultaneously adjusting for all three individual measures of SES for white men (p<0.001) and white women (p<0.05). Deaths would hypothetically be reduced by about 20% for each subgroup if everyone had the same death rates as those living in the highest SES neighbourhoods (highest tertile).ConclusionsLiving in a low SES neighbourhood confers additional mortality risk beyond individual SES.

Project description:OBJECTIVES:To investigate Black-White disparities in suboptimal sleep and cardiometabolic health by government-assisted rental housing status. DESIGN:National Health Interview Survey (NHIS) pooled cross-sectional data (2004-2016). SETTING:United States. PARTICIPANTS:Black and White adult participants (n?=?80,880). MEASUREMENTS:Poisson regression with robust variance was used to estimate prevalence ratios (PRs) and 95% confidence intervals for self-reported unrecommended (<6 hours), short (?6-<7 hours), and long (>9 hours) sleep duration (each separately vs recommended (?7-9 hours)) and sleep difficulties (eg, trouble falling/staying asleep ?3 days/week) (yes vs no) among Blacks compared to Whites within rental housing categories (government-assisted vs unassisted), separately, for men and women. Within sex/housing categories, we applied the same approach to compare cardiometabolic health outcomes (ie, overweight/obesity, hypertension, diabetes, heart disease, stroke) between Blacks with worse sleep and Whites with recommended sleep. Models were adjusted for age and other potential confounders. RESULTS:Participants' mean age was 42?±?18 years, 57% were female, and 30% Black. Blacks in unassisted housing had a higher prevalence of unrecommended and short sleep (PR?=?1.22 [1.15-1.30] -men, PR?=?1.14 [1.08-1.21] -women) compared to their White counterparts (phousing?race?=?0.001 -men, phousing?race?=?0.008 -women), but no Black-White differences (PR?=?0.88 [0.73-1.07] -men, PR?=?0.98 [0.89-1.09] -women) were observed among government-assisted renters. Generally, Blacks were less likely to report sleep difficulties than Whites. Cardiometabolic health disparities between Blacks with worse sleep and Whites with recommended sleep were generally smaller among government-assisted renters, but relationships varied by sex. CONCLUSIONS:There were no racial disparities in short sleep duration, and cardiometabolic health disparities were generally attenuated when Blacks and Whites resided in government-assisted rental housing.

Project description:We examined children's sleep at age 9 as a predictor of developmental trajectories of cognitive performance from ages 9 to 11 years. The effects of sleep on cognition are not uniform and thus we tested race/ethnicity, socioeconomic status (SES), and sex as moderators of these associations. At the first assessment, 282 children aged 9.44 years (52% boys, 65% European American [EA], 35% African American [AA]) participated. Two more waves of data collection spaced 1 year apart followed. The majority of children (63%) were living at or below the poverty line. Children's sleep was measured objectively with actigraphy and 2 well-established sleep parameters were derived: duration, indexed by sleep minutes between sleep onset and wake time, and quality, indexed by efficiency. Multiple cognitive functioning domains were examined with the Woodcock Johnson Tests of Cognitive Abilities (WJ III). Across the sample, higher sleep efficiency, but not duration, was associated with better cognitive performance. Significant moderation effects emerged. Controlling for SES, AA children scored lower on general intellectual ability and working memory (WM) at age 11 only if they experienced lower sleep efficiency at age 9. Further, boys scored lower on general abilities and processing speed (PS) at age 11 only if their sleep efficiency was lower at age 9. Findings indicate that lower sleep efficiency may contribute to lower cognitive functioning especially for AA children and boys. These vulnerabilities appear to emerge early in development and are maintained over time. Results underscore the importance of individual differences in explicating relations between sleep and children's cognitive performance. (PsycINFO Database Record

Project description:The association between childhood socioeconomic status (SES) and brain development is an emerging area of research. The primary focus to date has been on SES and variations in gray matter structure with much less known about the relation between childhood SES and white matter structure. Using a longitudinal study of SES, with measures of income-to-needs ratio (INR) at age 9, 13, 17, and 24, we examined the prospective relationship between childhood SES (age 9 INR) and white matter organization in adulthood using diffusion tensor imaging. We also examined how changes in INR from childhood through young adulthood are associated with white matter organization in adult using a latent growth mixture model. Using tract-based spatial statistics (TBSS) we found that there is a significant prospective positive association between childhood INR and white matter organization in the bilateral uncinate fasciculus, bilateral cingulum bundle, bilateral superior longitudinal fasciculus, and corpus callosum (p?<?.05, FWE corrected). The probability that an individual was in the high-increasing INR profile across development compared with the low-increasing INR profile was positively associated with white matter organization in the bilateral uncinate fasciculus, left cingulum, and bilateral superior longitudinal fasciculus. The results of the current study have potential implications for interventions given that early childhood poverty may have long-lasting associations with white matter structure. Furthermore, trajectories of socioeconomic status during childhood are important-with individuals that belong to the latent profile that had high increases in INR having greater regional white matter organization in adulthood.
