Which aspects of education are health protective? a life course examination of early education and adulthood cardiometabolic health in the 30-year study of early child care and Youth Development (SECCYD).

BACKGROUND: Past research describes robust associations between education and health, yet findings have generally been limited to the examination of education as the number of years of education or educational attainment. Little is known about the specific features or processes underpinning education that are health protective. The objective of the current study was to address this gap by examining specific aspects of early education pertaining to student characteristics and experiences, as well as features of the classroom environment, in predicting cardiometabolic health in adulthood. METHODS: Subjects were 1364 participants in the NICHD Study of Early Child Care and Youth Development (SECCYD, 1991-2009) and recent SECCYD 30-year follow-up, the Study of Health in Early and Adult Life (SHINE, 2018-2022). Models examined individual education indicators (student social skills, student-teacher relationship quality, and classroom emotional and instructional quality in the period of elementary school and student academic performance between ages 54 months and 15 years) in relation to a composite of cardiometabolic risk in adulthood (ages 26-31), reflecting central adiposity, blood pressure, insulin resistance, inflammation, and dyslipidemia. Models were adjusted for key explanatory factors including socio-demographics, infant characteristics, parental socioeconomic status (SES), and child health status. Follow-up analyses were performed to test potential mediators of early education effects on adult health, including adult SES (educational attainment, household income) and health behaviors (diet quality, activity level, sleep duration, smoking). RESULTS: In adjusted models, results showed greater student social skills, indexed by a mean of annual teacher ratings between kindergarten and 6th grade, predicted lower cardiometabolic risk in adulthood (ß=-0.009, p <.05). In follow-up analyses, results showed the protective effect of student social skills on cardiometabolic risk may be mediated by adult income (ß=-0.0014, p <.05) and diet quality (ß=-0.0031, p <.05). Effects of the other early education indicators were non-significant (ps > 0.05). CONCLUSIONS: Findings point to the potential significance of early student social competence as a link to long-term health, possibly via the acquisition of resources needed for the maintenance of health, as well as through engagement in health behaviors supporting healthy eating. However, more research is needed to replicate these findings and to elaborate on the role of early student social competence and the pathways explaining its effects on cardiometabolic health in adulthood.

Effects of Early Life Adversity on Pubertal Timing and Tempo in Black and White Girls: The National Growth and Health Study.

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.

The relative contributions of adiposity and activity levels to physical performance in children with excess weight.

OBJECTIVE: This study examined predictors of physical performance, a key aspect of quality of life, in children with excess weight. METHODS: Participants were 269 children aged 6-12 years with a body mass index above the 85th percentile. Children completed a standardized physical performance task capturing lower extremity strength, balance, and gait speed. Height, weight, and waist circumference were objectively measured, and daily moderate-vigorous physical activity (min/day) and sedentary time (% of day) were assessed with a 7-day accelerometer protocol. RESULTS: Physical performance task completion averaged 15.0 (SD = 2.5) seconds. Children with higher body mass index z-scores and waist circumferences had significantly longer task completion times. The task took 1.8 additional seconds per 1.0 body mass index z-score (p < .001), and 1.2 additional seconds for every 20 cm higher waist circumference (p < .001). Daily moderate-vigorous physical activity and sedentary time were unrelated to physical performance, and did not moderate its associations with the adiposity measures. CONCLUSION: Among children with excess weight, physical performance declines with increasing levels of total and central adiposity. Daily activity levels do not moderate this association. Interventions that directly target weight reduction would likely yield the greatest improvement in physical performance in children with overweight or obesity.

Timing, duration, and differential susceptibility to early life adversities and cardiovascular disease risk across the lifespan: Implications for future research.

Early life adversities (ELA), include experiences such as child maltreatment, household dysfunction, bullying, exposure to crime, discrimination, bias, and victimization, and are recognized as social determinants of cardiovascular disease (CVD). Strong evidence shows exposure to ELA directly impacts cardiometabolic risk in adulthood and emerging evidence suggests there may be continuity in ELA's prediction of cardiometabolic risk over the life course. Extant research has primarily relied on a cumulative risk framework to evaluate the relationship between ELA and CVD. In this framework, risk is considered a function of the number of risk factors or adversities that an individual was exposed to across developmental periods. The cumulative risk exposure approach treats developmental periods and types of risk as equivalent and interchangeable. Moreover, cumulative risk models do not lend themselves to investigating the chronicity of adverse exposures or consider individual variation in susceptibility, differential contexts, or adaptive resilience processes, which may modify the impact of ELA on CVD risk. To date, however, alternative models have received comparatively little consideration. Overall, this paper will highlight existing gaps and offer recommendations to address these gaps that would extend our knowledge of the relationship between ELA and CVD development. We focus specifically on the roles of: 1) susceptibility and resilience, 2) timing and developmental context; and 3) variation in risk exposure. We propose to expand current conceptual models to incorporate these factors to better guide research that examines ELA and CVD risk across the life course.

Early Life Adversity and Pubertal Timing: Implications for Cardiometabolic Health.

OBJECTIVE: To identify early life adversity (ELA) risk factors for earlier pubertal timing, itself a risk factor for poor cardiometabolic health, and to determine whether such ELA-related risk may be mediated by pre-pubertal body mass index (BMI). METHODS: Subjects included 426 female participants in a prospective birth cohort study, the NICHD Study of Early Child Care and Youth Development. Survival analysis models were fit to examine ELA exposures, representing childhood socioeconomic status (SES), maternal sensitivity, mother-child attachment, and negative life events, along with child health indicators and covariates, in relation to pubertal timing outcomes, including age at menarche and ages at Tanner stage II for breast and pubic hair development. RESULTS: Higher childhood SES emerged as an independent predictor of older age at menarche, showing each one standard deviation increase in childhood SES corresponded to a 1.3% increase in age at menarche (factor change = 1.013; 1.003-1.022; p < .01), but did not predict breast or pubic hair development (ps > .05). In mediation analyses, indirect (mediated) effects of mother-child attachment on the pubertal timing outcomes, via pre-pubertal BMI, were all statistically significant (ps < .05). CONCLUSIONS: Higher childhood SES predicted directly, and secure (vs. insecure) mother-child attachment predicted indirectly (via pre-pubertal BMI), later pubertal timing, suggesting these factors may protect girls from earlier pubertal development. By extension, clinical implications are that intervention strategies designed to lessen ELA- and pre-pubertal obesity-related risk may be effective in remediating life course pathways linking ELA, accelerated pubertal development, and cardiometabolic risk.

Preexisting Executive Function Deficits and Change in Health Behaviors During the COVID-19 Pandemic.

BACKGROUND: Executive functions (EF) support engagement in goal-directed behaviors, including several health behaviors. Stressful and cognitively demanding events can disrupt EFs and interfere with health behavior, possibly to a greater extent in those with preexisting EF deficits. This study examined the association between preexisting EF deficits and subsequent negative changes in eating patterns, physical activity, sedentariness, and alcohol/substance use during the COVID-19 pandemic. METHOD: Participants were 374 young adults in a follow-up study of the longitudinal, multisite Study of Early Child Care and Youth Development (SECCYD). Preexisting EF deficits were assessed with the Barkley Deficits in Executive Function Scales-Short Form, and personally impactful negative changes in four health behaviors (physical activity, unhealthy eating, sedentary time, alcohol/substance use) during the COVID-19 pandemic were subsequently assessed with the Epidemic-Pandemic Impacts Inventory. RESULTS: In ordered logistic regression models, higher preexisting total EF deficits were associated with greater negative impactful changes in physical activity and unhealthy eating, independent of sociodemographic variables, obesity, and (as relevant) accelerometer-based physical activity and pre-COVID-19 diet quality. Socioeconomic status moderated the association between total EF deficits and impactful change in alcohol/substance use, with EF deficits linked to greater impactful change in alcohol/substance use only in higher socioeconomic strata. CONCLUSION: Individuals with preexisting EF deficits appear more vulnerable to the negative impact of the COVID-19 pandemic on several key health behaviors. As the pandemic unfolds, strategies may be needed to identify those with EF deficits (e.g., screening tools) and provide them with tailored support for chronic disease risk reduction.

Does secure base script knowledge mediate associations between observed parental caregiving during childhood and adult romantic relationship quality and health?

Increasingly, attachment representations are being assessed via secure base script knowledge - the degree to which individuals show awareness of the temporal-causal schema that summarizes the basic features of seeking and receiving effective support from caregivers during times of need. Limited research has assessed the links between secure base script knowledge and aspects of adult functioning and the role that secure base script knowledge may play in accounting for associations between early caregiving quality and adulthood functioning. We used follow-up assessments of the NICHD Study of Early Child Care and Youth Development cohort (N = 585) to examine whether secure base script knowledge at age 18 years: (a) is associated with later romantic relationship quality, depressive symptoms, and body mass index (BMI) at age 26 years, and (b) mediates expected associations between the quality of maternal and paternal sensitivity across the first 15 years of life and age-26 outcomes. More access to, and elaborated knowledge of the secure base script predicted less extreme hostility with romantic partners, and better emotional and physical health. Moreover, secure base script knowledge mediated the links between early maternal and paternal sensitivity and both later romantic partner hostility and depressive symptoms, but not BMI.

Neighborhood socioeconomic status during childhood versus puberty in relation to endogenous sex hormone levels in adult women.

BACKGROUND: Socioeconomic adversity in early life is related to cardiovascular risk in adulthood; however, no studies have examined whether such adversity may be related to endogenous sex hormones, which are themselves associated with cardiovascular outcomes, or whether the timing of adversity exposures (childhood vs. puberty) matters. OBJECTIVE: The goal of the current study was to separately examine neighborhood socioeconomic status (SES) during periods of childhood and puberty in relation to adulthood levels of endogenous sex hormones (estradiol [E2], testosterone), sex hormone binding globulin (SHBG), and a derived index of bioavailable testosterone (free androgen index). METHODS: In a sample of 143 premenopausal women (mean age = 36.8 [SD = 5.5]; 51.7% White, 32.2% African American, 5.6% Latina, 7.0% Chinese, and 3.5% Filipina), retrospective reports of residential address information in designated periods of childhood and puberty were used to derive U.S. census-based neighborhood SES composite scores characterizing the socioeconomic environments of women during these periods. RESULTS: In covariate-adjusted analyses, higher neighborhood SES in puberty predicted higher levels of SHBG in adulthood, but neighborhood SES during childhood did not (standardized regression coefficient = .24, p = .01 vs. standardized regression coefficient = .04, p = .75, respectively). Neighborhood SES was not predictive of other hormones (E2, testosterone, and free androgen index). DISCUSSION: The current findings suggest that puberty may be a time of particular vulnerability to the effects of neighborhood SES on SHBG levels, which have been linked to cardiovascular risk factor profiles and atherosclerotic disease progression.

Association between neighborhood poverty and ovarian reserve: the ovarian aging study.

OBJECTIVE: This study aimed to examine the association between neighborhood poverty and ovarian reserve. METHODS: Among 1,019 healthy premenopausal women in the Ovarian Aging Study, aggregate exposure to neighborhood poverty was examined in relation to biomarkers of ovarian reserve, antimüllerian hormone (AMH) and antral follicle count (AFC). Specifically, the interaction of age-x-neighborhood poverty was assessed cross-sectionally to determine whether AMH and AFC declines across women may be greater in women exposed to more neighborhood poverty. Neighborhood poverty was assessed by geocoding and linking women's residential addresses in adulthood to US Census data. RESULTS: Independent of covariates, a significant interaction term showed the association between age and AMH varied by degree of exposure to neighborhood poverty in adulthood ( b = -0.001, P < 0.05). AMH declines increased progressively across women exposed to low, medium, and high levels of neighborhood poverty. In addition, main effects showed that higher neighborhood poverty was related to higher AMH in the younger women only ( b = 0.022, P < 0.01). Results related to AFC were all nonsignificant ( P > 0.05). CONCLUSIONS: Across women, greater aggregate exposure to neighborhood poverty in adulthood was related to lower ovarian reserve, indexed by AMH. In addition, there was a positive association between neighborhood poverty and AMH in younger women that attenuated in the older women. Together, results suggest that neighborhood disadvantage may have detrimental impacts that manifest as initially higher AMH, resulting in greater ovarian follicle loss over time. However, it remains unclear whether these results examining differences across women may replicate when AMH declines by neighborhood poverty are examined longitudinally.

Pubertal timing: A life course pathway linking early life risk to adulthood cardiometabolic health.

OBJECTIVE: To evaluate a series of prospective life course models testing whether the timing of pubertal development is a pathway through which prepubertal risk factors may influence adulthood cardiometabolic health. METHODS: Subjects were 655 female participants in the NICHD Study of Early Child Care and Youth Development (SECCYD) and recent SECCYD 30-year follow-up, the Study of Health in Early and Adult Life (SHINE). Prepubertal risk factors included maternal menarcheal age, child race/ethnicity, child health status indicators, and child adversity indicators. Pubertal timing was indexed by breast development onset (Tanner stage [TS] II), pubic hair onset (TS II) and menarcheal age. Adulthood cardiometabolic risk (CMR) was indexed by a composite of waist circumference, systolic blood pressure, diastolic blood pressure, hemoglobin A1c, C-reactive protein, and high-density lipoprotein. RESULTS: Inspection of paths between the prepubertal risk factors, pubertal timing indicators, and adulthood CMR composite showed later breast development onset (-0.173, p < .01), later pubic hair onset (-0.182, p < .01), and later menarche (-0.145, p < .01) each predicted lower adulthood CMR, and each pubertal timing indicator mediated effects of prepubertal risk factors on adulthood CMR. Specifically, the timing of breast development onset and menarche mediated effects of maternal menarcheal age, Black (vs. White), Asian/PI (vs. White), child BMI percentile, and child SES on adulthood CMR (all ps < .05), and the timing of pubic hair onset mediated effects of maternal menarcheal age, Black (vs. White), and child BMI percentile on adulthood CMR (all ps < .10). CONCLUSION: Findings in the current study contribute to the broader literature by identifying pubertal development and its timing as a potentially important pathway through which early life exposures may shape adulthood cardiometabolic health and disease. These findings have important implications for novel opportunities for increased surveillance and potential intervention focusing on pubertal development as a target to improve health more broadly.

Thirty-year follow-up of the NICHD Study of Early Child Care and Youth Development (SECCYD): the challenges and triumphs of conducting in-person research at a distance.

PURPOSE: The purpose of the current study, The National Institute of Child Health and Human Development (NICHD) Study of Health in Early and Adult Life (SHINE), was to build on the landmark Study of Early Child Care and Youth Development (SECCYD), a longitudinal birth cohort initiated in 1991, by conducting a health-focused follow-up of the now adult participants. This effort has produced an invaluable resource for the pursuit of life course research examining links between early life risk and resilience factors and adulthood health and disease risk. PARTICIPANTS: Of the 927 NICHD SECCYD participants available for recruitment in the current study, 705 (76.1%) participated in the study. Participants were between 26 and 31 years and living in diverse geographic locations throughout the USA. FINDINGS TO DATE: In descriptive analyses, the sample exhibited risk on health status indicators, especially related to obesity, hypertension and diabetes. Of particular concern, the prevalence of hypertension (29.4%) and diabetes (25.8%) exceeded national estimates in similar-age individuals. Health behaviour indicators generally tracked with the parameters of poor health status, showing a pattern of poor diet, low activity and disrupted sleep. The juxtaposition of the sample's relatively young age (mean=28.6 years) and high educational status (55.6% college educated or greater) with its poor health status is noteworthy, suggesting a dissociation between health and factors that are typically health protective. This is consistent with observed population health trends, which show a worsening of cardiometabolic health status in younger generations of Americans. FUTURE PLANS: The current study, SHINE, lays the groundwork for future analyses in which the uniquely robust measures collected as a part of the original NICHD SECCYD will be leveraged to pinpoint specific early life risk and resilience factors as well as the correlates and potential mechanisms accounting for variability in health and disease risk indicators in young adulthood.

Fertility treatment response: is it better to be more optimistic or less pessimistic?

OBJECTIVE: To evaluate the prospective relation between dispositional traits of optimism and pessimism and in vitro fertilization (IVF) treatment failure among women seeking medical intervention for infertility. METHODS: Among 198 women (aged 24-45 years, mean [standard deviation] = 35.1 [4.1] years; white, 77%), the outcome of each participant's first IVF treatment cycle was examined. Treatment outcome was classified as being successful (versus failed) if the woman either delivered a baby or was pregnant because of the cycle by the end of the 18-month study period. At baseline, optimism and pessimism were measured as a single bipolar dimension and as separate unipolar dimensions according to the Life Orientation Test total score and the optimism and pessimism subscale scores, respectively. RESULTS: Optimism/pessimism, measured as a single bipolar dimension, predicted IVF treatment failure initially (B = -0.09, p = .02, odds ratio [OR] = 0.917, 95% confidence interval [CI] = 0.851-0.988), but this association attenuated after statistical control for trait negative affect (B = -0.06, p = .13, OR = 0.938, 95% CI = 0.863-1.020). When examined as separate unipolar dimensions, pessimism (B = 0.14, p = .04, OR = 1.146, 95% CI = 1.008-1.303), not optimism (B = -0.09, p = .12, OR = 0.912, 95% CI = 0.813-1.023), predicted IVF treatment failure independently of risk factors for poor IVF treatment response and trait negative affect. CONCLUSIONS: Being pessimistic may be a risk factor for IVF treatment failure. Future research should attempt to delineate the biological and behavioral mechanisms by which pessimism may negatively affect treatment outcomes.

Disparities in COVID-19-related stressful life events in the United States: Understanding who is most impacted.

Impacts of the COVID-19 pandemic in the United States have been exacerbated by pre-existing inequities in resources and opportunities, leaving the most vulnerable to face a multitude of hardships. The goal of the current study was to characterise COVID-19-related stressful life events in specific life domains and to identify the sociodemographic characteristics of individuals who are more likely to experience such events. Participants (n = 372, 57% female) in a follow-up study of the NICHD Study of Early Child Care and Youth Development completed the Epidemic-Pandemic Impacts Inventory (June-August 2020) to assess COVID-19-related stressors. Sociodemographic factors (gender, race/ethnicity, socioeconomic status and wealth) were examined simultaneously as predictors of the number of stressful life events in separate categories of work/finances, home life, social activity, health and healthcare, adjusted for covariates (household size, community COVID-19 transmission risk). In negative binomial regression analyses, being female (vs. male) predicted a 31%, 64%, 13% and 94% increase in the number of stressful life events in domains of work/finances, home life, social activity and healthcare, respectively, whereas each one standard deviation increase in wealth predicted a 17%, 16% and 21% reduction in the number of stressful life events in domains of work/finances, COVID-19 infection and healthcare, respectively. Findings highlight the pronounced and far-reaching impacts of the COVID-19 pandemic on women as well as the unique role wealth may play in lessening such impacts. This new knowledge may be leveraged to develop intervention and policy-related strategies to remediate impacts of COVID-19-related stressors on those most vulnerable.

Early maternal sensitivity and markers of physical health: Enduring or transient associations from childhood to adulthood?

Individual differences in the quality of early experiences with primary caregivers have been reliably implicated in the development of socioemotional adjustment and, more recently, physical health. However, few studies have examined the development of such associations with physical health into the adult years. To that end, the current study used prospective, longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,306, 52% male, 77% White/non-Hispanic) to investigate whether associations between direct observations of maternal sensitivity in the first 3 years of life and repeated assessments of two commonly used, objective indicators of physical health (i.e., body mass and mean arterial blood pressure) remained stable or diminished in magnitude over time. Associations between early maternal sensitivity and lower body mass remained relatively stable from age 54 months to 26 years and were robust to the modeling of autoregressive and second-order stability processes as well as the inclusion of potential demographic confounders. In contrast, although associations between early caregiving and lower mean arterial pressure remained relatively stable from Grade 4 to age 15 years (the oldest age for which mean arterial pressure was assessed thus far), these associations were not robust to the inclusion of covariates and the modeling of second-order stability processes.

Adverse childhood experiences and repeat induced abortion.

OBJECTIVE: The objective of the study was to characterize the backgrounds of women who have repeat abortions. STUDY DESIGN: In a cross-sectional study of 259 women (mean age, 35.2 ± 5.6 years), the relation between adverse experiences in childhood and risk of having 2 or more abortions vs 0 or 1 abortion was examined. Self-reported adverse events occurring between the ages of 0 and 12 years were summed. RESULTS: Independent of confounding factors, women who experienced more abuse, personal safety, and total adverse events in childhood were more likely to have 2 or more abortions vs 0 abortions (odds ratio [OR], 2.56; 95% confidence interval [CI], 1.15-5.71; OR, 2.74; 95% CI, 1.29-5.82; and OR, 1.59; 95% CI, 1.21-2.09, respectively) and vs 1 abortion (OR, 5.83; 95% CI, 1.71-19.89; OR, 2.23; 95% CI, 1.03-4.81; and OR, 1.37; 95% CI, 1.04-1.81, respectively). Women who experienced more family disruption events in childhood were more likely to have 2 or more abortions vs 0 abortions (OR, 1.75; 95% CI, 1.14-2.69) but not vs 1 abortion (OR, 1.16; 95% CI, 0.79-1.70). CONCLUSION: Women who have repeat abortions are more likely to have experienced childhood adversity than those having 0 or 1 abortion.

Targeting Parenting Quality to Reduce Early Life Adversity Impacts on Lifespan Cardiometabolic Risk.

Mounting evidence that early life adversity (ELA) exposures confer risk for cardiometabolic disease over the lifespan motivated this narrative review to examine parenting quality as a potential intervention target to reduce ELA exposures or mitigate their impact as a way of reducing or preventing cardiometabolic disease. We describe findings from the limited number of family-based intervention studies in ELA-exposed children that have tested parenting impacts on cardiometabolic health outcomes. We then describe the implications of this work and make recommendations for future research that will move this field forward.

Randomized trial of promoting first relationships for new mothers who received community mental health services in pregnancy.

The effectiveness of Promoting First Relationships (PFR), a 10-week home visiting program with video feedback, was tested in a randomized controlled trial involving 252 mothers and their 8- to 12-week-old infants. Mothers were eligible if they initiated treatment after mental health screening (depression, anxiety, posttraumatic stress disorder [PTSD]) at a community or public health primary care center in pregnancy. At baseline, 51% had mild to severe depression symptoms, 54% had mild to severe anxiety, and 35% had PTSD. Their ages ranged from 18 to 42 years. Mothers were 66% White, 18% Black, and 16% other races. Forty-seven percent identified as Hispanic, and 33% preferred to read and speak in Spanish. The median family annual income was less than $20,000. The PFR program or receipt of a resource packet (control condition) followed the baseline assessment and randomization; we assessed outcomes when infants were age 6 and 12 months. Compared to mothers in the control condition, mothers in the PFR condition had significantly (ps < .05) higher observed sensitivity scores at both follow-up time points (d = .25, d = .26), had improved understanding of infant-toddler social-emotional needs at both time points (d = .21, d = .45), and reported less infant externalizing behavior at age 12 months (d = .28). This study is the fourth completed randomized controlled trial of the PFR program, all involving populations experiencing adversity. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Patterns of Early Life Weight Gain and Female Onset of Puberty.

Context: Prepubertal obesity is a well-established predictor of earlier pubertal onset, which is itself a risk factor for poor health and well-being. Identifying specific patterns of weight gain in early life may help explain differential risk for earlier pubertal onset. Objective: The objective of the study was to examine patterns of weight gain across infancy and early childhood in relation to pubertal onset outcomes. Design Setting and Participants: Participants were 426 girls in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, a longitudinal birth cohort of children and their families followed between birth and adolescence. Main Outcome Measures: Three pubertal onset outcomes were examined, including age at menarche and ages at Tanner stage II for dimensions of breast and pubic hair development. Results: In infancy (birth to 15 months), greater percent weight gain and higher birthweight predicted earlier pubertal onset for all outcomes (Ps < 0.05). In early childhood (24 months to grade 1), body mass index (BMI) trajectories reflecting BMI values that were persistently high or changed from low to high over time (vs BMI values that were stable at median or low levels), predicted younger ages at menarche and the onset of breast (Ps < 0.05), but not pubic hair (Ps > 0.05), development. All associations were independent of breastfeeding, maternal menarcheal age, and race/ethnicity. Conclusions: Distinct patterns of early life weight gain predict differential risk for earlier onset puberty. Focusing on these patterns for earlier and more targeted intervention may help lessen life course linkages between prepubertal obesity, accelerated pubertal development, and negative postpubertal outcomes.

Early life predictors of positive change during the coronavirus disease pandemic.

BACKGROUND: The COVID-19 pandemic is a crisis unprecedented in its size and scope. Yet studies of resilience suggest most individuals will successfully negotiate this challenge and some may even experience growth and positive change. Some evidence suggests that the capacity to enact positive change in the face of adversity may be shaped by early life experiences. METHODS: In a subset of 374 participants (57% female, mean age = 29 years) in the Study of Early Child Care and Youth Development (SECCYD), a longitudinal, birth cohort, prospective models were tested to determine whether early life adversities in family and neighborhood contexts predict positive change events in response to the COVID-19 pandemic. Childhood family and neighborhood contexts were assessed using a combination of self-report questionnaires and US Census data. Adulthood positive change events (e.g., becoming more appreciative of things usually taken for granted) were assessed using the Epidemic-Pandemic Impacts Inventory (EPII). RESULTS: In regression analyses, neighborhood disadvantage in childhood, measured both by objective and subjective assessments, predicted a higher number of positive change events in response to the COVID-19 pandemic (ß = .18, p = .004 and ß = .15, p = .006, respectively). Examination of the positive change event subscales showed neighborhood disadvantage in childhood predicted increases in events related to 'perspective taking and charitable giving' (ß = .20, p = .022 and ß = .17, p = .002, respectively) and improved 'social relationships' (ß = .18, p = .004 and ß = .13, p = .020, respectively), but not to positive 'health behaviors' (ps > .05). All associations were independent of sociodemographic factors and childhood family dysfunction. CONCLUSIONS: Findings suggest that neighborhood disadvantage in childhood may shape prosocial responses to stress in adulthood, potentially through early life adaptions to stress that are protective when facing adversity. There are several notable implications of the study findings. Although adversity in early life has clear negative impacts, it is possible that adversity experiences may also provide opportunities to develop adaptive strategies that foster resilience and growth when facing stress. Intervention efforts should consider leveraging such stress-adapted strengths to reduce the many negative impacts of early life adversity.
