- Abstract
We examined three generations (grandparents, mothers, and grandchildren) to assess the association between grandparents' educational attainment and their grandchildren's epigenetic-based age acceleration and whether the association was mediated by parental educational attainment and mothers' life course health-related factors. Mothers were recruited to the NHLBI Growth and Health Study at 9-10 years and followed for 10 years (1987-1998). Mothers were then re-contacted three decades later (ages 37-42) to participate in the National Growth and Health Study (NGHS), and health information from their youngest child (i.e., grandchildren; N = 241, ages 2-17) was collected, including their saliva samples to calculate epigenetic age. Five epigenetic-based age acceleration measures were included in this analysis, including four epigenetic clock age accelerations (Horvath, Hannum, GrimAge, and PhenoAge) and DunedinPACE. Grandparents reported their highest education during the initial enrollment interviews. Parental educational attainment and mothers' life course health-related factors (childhood BMI trajectories, adult cardiovascular health behavioral risk score, and adult c-reactive protein) are included as mediators. Grandparents' education was significantly associated with Horvath age acceleration (b = -0.32, SE = 0.14, p = 0.021). Grandchildren with college-degree grandparents showed significantly slower Horvath age accelerations than those without college degrees. This association was partially mediated by parental education and mothers' health-related factors, especially adult cardiovascular health behavioral risk score and CRP, but not mothers' childhood BMI trajectory. This ability to conserve the speed of biological aging may have considerable consequences in shaping health trajectories across the lifespan., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Importance: Low childhood socioeconomic status (SES) is a social hallmark of aging that contributes to adult health disparities and earlier morbidity and mortality. Childhood perceptions of stress are associated with child health outcomes and may contribute to premature biological aging into adulthood., Objective: To describe the association of childhood SES and perceived stress with midlife insulin resistance and epigenetic age and to explore whether late adolescent adiposity mediates the observed associations., Design, Setting, and Participants: The longitudinal cohort National Heart, Lung, and Blood Institute Growth and Health Study enrolled girls aged 10 years from January 1987 to May 1988, and followed them up to 19 years of age. Participants from Richmond, California, were recruited again at midlife in 2016 to assess insulin resistance and epigenetic age. Analyses were conducted from August 2, 2023, to March 18, 2024. A total of 433 participants were eligible and included in the analyses (specific sample sizes ranged across analyses from 303 to 391)., Exposures: Childhood levels of SES at 10 years of age (parental educational level and income) and perceived stress at 11 years of age., Main Outcomes and Measures: The hypotheses tested were formulated after data collection. Outcomes included the homeostatic model assessment of insulin resistance (HOMA-IR) and the GrimAge and DunedinPACE epigenetic clocks. Waist circumference in late adolescence was tested as a mediator., Results: Among the 433 participants, the mean (SD) age was 39.4 (1.2) years; 218 (50.3%) were Black and 215 (49.7%) were White; and 135 (31.2%) had parents with a college degree or higher. Higher parental educational level was associated with lower HOMA-IR (B = -0.22 [95% CI, -0.41 to -0.02]; P = .03), lower midlife GrimAge (B = -1.76 [95% CI, -2.85 to -0.66] years; P = .002), and slower midlife DunedinPACE (B = -0.03 [95% CI, -6.29 to -0.002]; P = .04). Childhood perceived stress was indirectly associated through late adolescent adiposity with midlife HOMA-IR (B = 0.01 [95% CI, 0.001-0.01]; P = .02) and midlife GrimAge (B = 0.02 [95% CI, 0.003-0.04] years; P = .01)., Conclusions and Relevance: In this longitudinal cohort study of midlife health and aging, childhood social hallmarks of aging were associated with midlife insulin resistance and epigenetic age (GrimAge and DunedinPACE). Future studies should identify malleable factors that may slow the impact of social hallmarks of aging.

- Abstract
Background: The current study examined if early adversity was associated with accelerated biological aging, and if effects were mediated by the timing of puberty., Methods: In early mid-life, 187 Black and 198 White ( M
age = 39.4, s.d.age = 1.2) women reported on early abuse and age at first menstruation (menarche). Women provided saliva and blood to assess epigenetic aging, telomere length, and C-reactive protein. Using structural equation modeling, we created a latent variable of biological aging using epigenetic aging, telomere length, and C-reactive protein as indicators, and a latent variable of early abuse using indicators of abuse/threat events before age 13, physical abuse, and sexual abuse. We estimated the indirect effects of early abuse and of race on accelerated aging through age at menarche. Race was used as a proxy for adversity in the form of systemic racism., Results: There was an indirect effect of early adversity on accelerated aging through age at menarche ( b = 0.19, 95% CI 0.03-0.44), in that women who experienced more adversity were younger at menarche, which was associated with greater accelerated aging. There was also an indirect effect of race on accelerated aging through age at menarche ( b = 0.25, 95% CI 0.04-0.52), in that Black women were younger at menarche, which led to greater accelerated aging., Conclusions: Early abuse and being Black in the USA may both induce a phenotype of accelerated aging. Early adversity may begin to accelerate aging during childhood, in the form of early pubertal timing.- Published

- Abstract
Background: The number of breast cancer survivors is increasing, yet evidence to inform dietary and lifestyle guidelines is limited., Methods: This analysis included 3,658 participants from the Pathways Study, a prospective cohort of women diagnosed with invasive breast cancer. A healthy plant-based dietary index score (hPDI), an American Cancer Society (ACS) nutrition guidelines score, a 2015 Healthy Eating Index score (HEI), hours per week of moderate to vigorous physical activity (PA), and lifetime cumulative pack-years of cigarette smoking (SM) were each measured at diagnosis, 6, 24, and 72 months. Using g-computation, 5- and 10-year risk ratios (RR), risk differences, and 95% confidence intervals (CI) for all-cause mortality under hypothetical interventions on diet quality, PA, and SM, compared with the natural course (no intervention) were calculated., Results: Hypothetical moderate to extreme interventions on hPDI, ACS, and HEI, each in combination with PA and SM, showed 11% to 56%, 9% to 38%, and 9% to 49% decreases in 5-year risks of all-cause mortality compared with no intervention, respectively [(hPDI: RRmoderate = 0.89, 95% CI: 0.82-0.94; RRextreme = 0.44, 95% CI: 0.26-0.67), (ACS: RRmoderate = 0.91, 95% CI: 0.85-0.96; RRextreme = 0.62, 95% CI: 0.43-0.82), (HEI: RRmoderate = 0.91, 95% CI: 0.84-0.95; RRextreme = 0.51, 95% CI: 0.33-0.72)]. While 10-year relative risks were slightly attenuated, absolute risk reductions were more pronounced., Conclusions: Interventions to improve diet quality, increase PA, or reduce SM at the time of diagnosis may improve survival among breast cancer survivors., Impact: We estimate that over 10% of deaths could be delayed by even moderate adoption of these behaviors., (©2023 American Association for Cancer Research.)

- Abstract
Purpose: The National Heart, Lung and Blood Institute Growth and Health Study (NGHS) prospectively collected anthropometric, biospecimens, clinical, health behaviour and psychosocial measures associated with cardiovascular disease from childhood to young adulthood. The aim of the current study was to assess the impact of stress, dysregulated eating and social genomic biomarkers on cardiometabolic risk factors among the original participants now in midlife and their children., Participants: Beginning in 1987-1988, NGHS recruited black and white girls (age 9-10 years) from socioeconomically diverse backgrounds from from three sites: Cincinnati, Ohio; Washington, DC; and Western Contra Costa County, California (N=2379) and followed them for 10 years. The study maintained an 89% retention rate. The current study is 30 years after the start of the original study and focused on the participants of California (n=887) and their children aged 2-17 years. We re-enrolled 624 of 852 eligible participants (73%): 49.2% black and 50.8% white. The mean age was 39.5 years. Among the 645 eligible biological children, 553 were enrolled; 49% black and 51% white, with 51.5% girls and 48.5% boys. The mean age was 9.3 years., Findings to Date: Longitudinal analysis of adolescent drive for thinness predicted higher scores for drive for thinness during midlife, which was indirectly associated with greater adult body mass index through adult drive for thinness. Latent trajectory modelling of adolescent growth over 10 years found that women with persistently high weight trajectory had twice the odds of having children who met the definition for obesity compared with the persistently normal group, adjusting for adult weight., Future Plans: New studies on neighbourhood socioeconomic status, food insecurity and additional biomarkers of chronic stress, microbiome and accelerated ageing (ie, telomere length and epigenetic clock) are underway. We are developing a 10-year follow-up to understand changes in ageing biomarkers of the participants and their children., Trial Registration Number: NCT00005132., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

- Abstract
Evidence suggests that adversity experienced during fetal development may shape infant physiologic functioning and temperament. Parental sensitivity is associated with child stress regulation and may act as a buffer against risk for intergenerational health effects of pre- or postnatal adversity. Building upon prior evidence in a racially and ethnically diverse sample of infants (M infant age = 6.5 months) and women of low socioeconomic status, this study examined whether coded parenting sensitivity moderated the association between an objective measure of prenatal stress exposures (Stressful Life Events (SLE)) and infant parasympathetic (respiratory sinus arrhythmia; RSA) or sympathetic (pre-ejection period; PEP) nervous system functioning assessed during administration of the Still-Face-Paradigm (SFP) ( n = 66), as well as maternal report of temperament ( n = 154). Results showed that parental sensitivity moderated the associations between prenatal stress exposures and infant RSA reactivity, RSA recovery, PEP recovery, and temperamental negativity. Findings indicate that greater parental sensitivity is associated with lower infant autonomic nervous system reactivity and greater recovery from challenge. Results support the hypothesis that parental sensitivity buffers infants from the risk of prenatal stress exposure associations with offspring cross-system physiologic reactivity and regulation, potentially shaping trajectories of health and development and promoting resilience.

- Abstract
Background: Early childhood is a pivotal period for the development of healthy eating practices. One way to promote child health is to identify early modifiable factors that affect child eating and weight. Given the intergenerational transmission of eating behaviors, this study examined how mothers' eating behaviors were associated with child feeding practices, and whether child weight-for-length (z-WFL) moderated this relation, in a community sample., Methods: Participants were 72 mother-child dyads. Maternal eating behaviors-emotional, external and restrained-were assessed 9-months postpartum, using the Dutch Eating Behavior Questionnaire. Child feeding-restrictive, pressure, and concern about overeating/overweight or undereating/underweight-was measured using the Infant Feeding Questionnaire, and child z-WFL were assessed 18-months postpartum. Linear regressions were used to test the main effect of maternal eating and the interaction effect of maternal eating and child z-WFL, on child feeding practices., Results: Maternal restrained eating was associated with child pressure feeding, and contrarily with concerns about overeating/overweight. However, a significant interaction between child z-WFL and both maternal emotional and external eating were found with regard to concern about child undereating/underweight. Paradoxically, among children who weighed more, greater maternal emotional and greater external eating were associated with greater concern about child undereating/underweight., Conclusions: In this community sample, mothers were more likely to report contradictory feeding practices and concerns, suggesting complicated relations among a mother's own eating behavior, her child's weight, and her perceptions of child eating and weight. This may indicate a need for better communication and support of infant feeding practices., Trial Registration: Data was collected as part of two grants (MAMAS Grant ID: HL097973-01; SEED Grant ID: HL116511-02) conducted at the University of California, San Francisco (UCSF). All subjects gave their informed consent for inclusion before they participated in the study. The study was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by institutional review board at UCSF., (© 2023. The Author(s).)

- Abstract
Objective: Depression is a public health crisis, and scalable, affordable interventions are needed. Although many psychosocial interventions are effective, there is little research investigating their sustained, long-term influence on well-being. The purpose of this study was to examine whether a prenatal mindfulness intervention with demonstrated benefit for women's depressive symptoms during the early postpartum period would exert effects through 8 years., Method: The sample of 162 lower income women was racially and ethnically diverse. Women were assigned to receive an 8-week mindfulness-based intervention during pregnancy (MIND) or treatment as usual (TAU). Repeated assessments of depressive symptoms were collected using the Patient Health Questionnaire-9 at baseline, postintervention, and following childbirth (1, 2, 3-4, 5, 6, and 8 years from baseline). The most recent assessment of depressive symptoms was collected during the COVID-19 pandemic., Results: MIND and TAU women were equivalent on sociodemographic factors and depressive symptoms at baseline. Depressive symptoms at all follow-up assessments through 8 years were significantly lower among women in MIND compared to TAU. The odds of moderate or higher depressive symptoms were greater among TAU compared to MIND women at all time points except the 6-year assessment. By Year 8, 12% of women in MIND reported moderate or more severe depressive symptoms compared to 25% of women in TAU., Conclusions: Results suggest the effects of a group-based psychosocial intervention during pregnancy may endure for years, well beyond the initial perinatal period. Investing in prevention and intervention efforts for mental health during pregnancy may have sustained benefits for the well-being of women.

- Abstract
Objective: Subjective social status (SSS), an individual's assessment of their own social status in relation to others, is associated with health and mortality independently of objective SES; however, no studies have tested whether SSS influences epigenetic aging. The current study examines if SSS is associated with epigenetic age acceleration in both Black and White women, independently of objective SES measured during both childhood and adulthood., Method: For 9- and 10-year-old Black and White girls, parental education and annual household income was obtained. At ages 39-42, 361 participants (175 Black, 186 White) reported their current education, household income, and SSS, and provided saliva to assess age acceleration using the GrimAge epigenetic clock. Linear regression estimated the association of SSS with epigenetic age acceleration, controlling for objective SES (current education, current income, parents' education, income during childhood), smoking, and counts of cell types., Results: When all objective SES variables were included in the model, SSS remained significantly associated with epigenetic age acceleration, b = - 0.31, p = .003, ß = - 0.15. Black women had significantly greater age acceleration than White women, (t(359) = 5.20, p > .001, d = 0.55) but race did not moderate the association between SSS and epigenetic age acceleration., Conclusions: Women who rated themselves lower in SSS had greater epigenetic age acceleration, regardless of income and education. There was no difference by race for this association., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

- Abstract
Objective: Maternal health and wellness during pregnancy are associated with long-term health outcomes in children. The current study examined whether infants of women who participated in a mindfulness-based intervention during pregnancy that reduced levels of stress and depression, increased physical activity, and improved glucose tolerance differed on biobehavioral markers of psychopathological and physical health risk compared with infants of women who did not., Methods: Participants were 135 mother-infant dyads drawn from a racially and ethnically diverse, low-income sample experiencing high stress. The women participated in an intervention trial during pregnancy that involved assignment to either mindfulness-based intervention or treatment-as-usual (TAU). Infants of women from both groups were assessed at 6 months of age on sympathetic (preejection period), parasympathetic (respiratory sinus arrhythmia), and observed behavioral (negativity and object engagement) reactivity and regulation during the still face paradigm. Linear mixed-effects and generalized linear mixed-effects models were used to examine treatment group differences in infant outcomes., Results: Relative to those in the intervention group, infants in the TAU group showed a delay in sympathetic activation and subsequent recovery across the still face paradigm. In addition, infants in the intervention group engaged in higher proportions of self-regulatory behavior during the paradigm, compared with the TAU group. No significant effect of intervention was found for parasympathetic response or for behavioral negativity during the still face paradigm., Conclusions: Findings provide evidence that maternal participation in a short-term, group mindfulness-based intervention during pregnancy is associated with the early development of salutary profiles of biobehavioral reactivity and regulation in their infants. Because these systems are relevant for psychopathology and physical health, prenatal behavioral interventions may benefit two generations., (Copyright © 2022 The Author(s).

- Abstract
Objective: Although exposure to abuse in early life predicts earlier pubertal timing, especially for girls, it is unclear if this association generalizes to nonabuse stressors. In addition, the impact of race on the stress-maturation association remains unknown. To address these issues, we examined whether race moderates the effects of early adversity on pubertal timing and tempo using a longitudinal study design., Methods: In a cohort of 9- and 10-year-old Black and White girls, pubertal (areolar and pubic hair) maturation was assessed annually for 7 years. In adulthood, 368 participants (186 Black, 182 White) reported on abuse and nonabuse stressors they experienced from ages 0 to 12 years., Results: Early life abuse was associated with earlier pubertal timing, as indexed by younger age at menarche (b = -0.22, p = .005, 95% confidence interval [CI] = -0.39 to -0.06) and greater pubic hair development (b = 0.11, p = .003, 95% CI = 0.04 to 0.18), in addition to slower pubertal tempo, as indexed by slower rate of pubic hair (b = -0.03, p < .001, 95% CI = -0.05 to -0.01) and areolar (b = -0.02, p = .02, 95% CI = -0.03 to -0.003) development. These associations were not found for nonabuse adversity. Black girls with early life abuse had greater pubic hair development (b = 0.23, p < .001, 95% CI = 0.12 to 0.35) and were slower in pubic hair tempo (b = -0.07, p < .001, 95% CI = -0.09 to -0.04) than their White counterparts., Conclusions: Screening for early life abuse may help address health disparities related to earlier pubertal timing., (Copyright © 2022 by the American Psychosomatic Society.)

- Abstract
The prevalence of overweight and obesity is greatest amongst Black women in the U.S., contributing to disproportionately higher type 2 diabetes prevalence compared to White women. Insulin resistance, independent of body mass index, tends to be greater in Black compared to White women, yet the mechanisms to explain these differences are not completely understood. The gut microbiome is implicated in the pathophysiology of obesity, insulin resistance and cardiometabolic disease. Only two studies have examined race differences in Black and White women, however none characterizing the gut microbiome based on insulin sensitivity by race and sex. Our objective was to determine if gut microbiome profiles differ between Black and White women and if so, determine if these race differences persisted when accounting for insulin sensitivity status. In a pilot cross-sectional analysis, we measured the relative abundance of bacteria in fecal samples collected from a subset of 168 Black (n = 94) and White (n = 74) women of the National Growth and Health Study (NGHS). We conducted analyses by self-identified race and by race plus insulin sensitivity status (e.g. insulin sensitive versus insulin resistant as determined by HOMA-IR). A greater proportion of Black women were classified as IR (50%) compared to White women (30%). Alpha diversity did not differ by race nor by race and insulin sensitivity status. Beta diversity at the family level was significantly different by race (p = 0.033) and by the combination of race plus insulin sensitivity (p = 0.038). Black women, regardless of insulin sensitivity, had a greater relative abundance of the phylum Actinobacteria (p = 0.003), compared to White women. There was an interaction between race and insulin sensitivity for Verrucomicrobia (p = 0.008), where among those with insulin resistance, Black women had four fold higher abundance than White women. At the family level, we observed significant interactions between race and insulin sensitivity for Lachnospiraceae (p = 0.007) and Clostridiales Family XIII (p = 0.01). Our findings suggest that the gut microbiome, particularly lower beta diversity and greater Actinobacteria, one of the most abundant species, may play an important role in driving cardiometabolic health disparities of Black women, indicating an influence of social and environmental factors on the gut microbiome., Competing Interests: The authors have declared that no competing interests exist.
