Childhood socioeconomic status and cardiovascular reactivity and recovery among Black and White men: Mitigating effects of psychological resources.

ABSTRACT: 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:BackgroundReducing disparities in men with prostate cancer (PCa) that may be caused by racial and socioeconomic differences is a major public health priority. Few reports have studied whether these disparities have changed over time.MethodsMen diagnosed with PCa from January 1, 2000 to December 31, 2015 were identified from the Massachusetts and Pennsylvania cancer registries. All-cause mortality and PCa and cardiovascular cause-specific mortality were assessed. To estimate neighborhood socioeconomic position (nSEP), a summary score was generated using census tract-level measures of income, wealth, educational attainment, and racial and income segregation. Participants were grouped by diagnosis year (2000-2003, 2004-2007, 2008-2011, or 2012-2015), and changing trends in the mortality rate ratio by race and nSEP were estimated using covariate-adjusted Cox models with follow-up for up to 10 years, until death, or until censoring on January 1, 2018.ResultsThere were 193,883 patients with PCa and 43,661 deaths over 1,404,131 person-years of follow-up. The Black-White adjusted hazard ratio (aHR) from 2000 to 2003 through 2012 to 2015 was stable for all-cause mortality (aHR, 1.14 to 0.97; P for heterogeneity = .42), decreased for PCa-specific mortality (aHR, 1.38 to 0.93; P for heterogeneity = .005), and increased for cardiovascular mortality (aHR, 1.09 to 1.28; P for heterogeneity = .034). The aHR comparing those in the lowest versus the highest nSEP quintile increased significantly for all-cause mortality (aHR, 1.54 to 1.79; P for heterogeneity = .008), but not for PCa-specific mortality (aHR, 1.60 to 1.72; P for heterogeneity = .40) or cardiovascular mortality (aHR, 1.72 to 1.89; P for heterogeneity = .085).ConclusionsAlthough Black-White disparities in prostate mortality declined in Massachusetts and Pennsylvania over the study period, nSEP mortality disparity trends were stagnant or increased, warranting further attention.Lay summaryFew reports have examined whether racial and socioeconomic disparities in prostate cancer mortality have widened or narrowed in recent years. Using data from 2 state registries (Massachusetts and Pennsylvania) with differing intensities of government-mandated health insurance, trends in racial and neighborhood socioeconomic disparities were studied among Black and White men diagnosed from 2000 to 2015. Overall, trends in racial disparities were stagnant for all-cause mortality, shrank for prostate mortality, and widened for cardiovascular mortality. Disparities associated with neighborhood socioeconomic status either were stagnant or widened across all mortality end points. In general, disparities were more pronounced in Pennsylvania than in Massachusetts.

Project description:Research on resilience after trauma has often focused on individual-level factors (eg, ability to cope with adversity) and overlooked influential neighborhood-level factors that may help mitigate the development of posttraumatic stress disorder (PTSD). To investigate whether an interaction between residential greenspace and self-reported individual resources was associated with a resilient PTSD trajectory (ie, low/no symptoms) and to test if the association between greenspace and PTSD trajectory was mediated by neural reactivity to reward. As part of a longitudinal cohort study, trauma survivors were recruited from emergency departments across the US. Two weeks after trauma, a subset of participants underwent functional magnetic resonance imaging during a monetary reward task. Study data were analyzed from January to November 2023. Residential greenspace within a 100-m buffer of each participant's home address was derived from satellite imagery and quantified using the Normalized Difference Vegetation Index and perceived individual resources measured by the Connor-Davidson Resilience Scale (CD-RISC). PTSD symptom severity measured at 2 weeks, 8 weeks, 3 months, and 6 months after trauma. Neural responses to monetary reward in reward-related regions (ie, amygdala, nucleus accumbens, orbitofrontal cortex) was a secondary outcome. Covariates included both geocoded (eg, area deprivation index) and self-reported characteristics (eg, childhood maltreatment, income). In 2597 trauma survivors (mean [SD] age, 36.5 [13.4] years; 1637 female [63%]; 1304 non-Hispanic Black [50.2%], 289 Hispanic [11.1%], 901 non-Hispanic White [34.7%], 93 non-Hispanic other race [3.6%], and 10 missing/unreported [0.4%]), 6 PTSD trajectories (resilient, nonremitting high, nonremitting moderate, slow recovery, rapid recovery, delayed) were identified through latent-class mixed-effect modeling. Multinominal logistic regressions revealed that for individuals with higher CD-RISC scores, greenspace was associated with a greater likelihood of assignment in a resilient trajectory compared with nonremitting high (Wald z test = -3.92; P < .001), nonremitting moderate (Wald z test = -2.24; P = .03), or slow recovery (Wald z test = -2.27; P = .02) classes. Greenspace was also associated with greater neural reactivity to reward in the amygdala (n = 288; t277 = 2.83; adjusted P value = 0.02); however, reward reactivity did not differ by PTSD trajectory. In this cohort study, greenspace and self-reported individual resources were significantly associated with PTSD trajectories. These findings suggest that factors at multiple ecological levels may contribute to the likelihood of resiliency to PTSD after trauma.
