Associations Between Maternal Caregiving and Child Indicators of Toxic Stress Among Multiethnic, Urban Families

The CARING study: Examining biological, behavioral, and genetic mechanisms in the intergenerational transmission of toxic stress

When children experience extreme or persistent stressors (e.g., maltreatment, housing insecurity, intimate partner violence), prolonged elevation of the stress-response system can lead to disrupted development of multiple physiological systems. This response, known as toxic stress, is associated with poor physical and mental health across the life course. Emerging evidence suggests that the effects of toxic stress may be transmitted through generations, but the biological and behavioral mechanisms that link caregivers' childhood history with the health of the children they care for remain poorly understood. The purpose of this report is to describe the research protocol for The CARING (Childhood Adversity and Resilience In the Next Generation) Study, a cross-sectional study of caregivers with children aged 3-5 years designed to (1) examine the intergenerational transmission of toxic stress and protective factors; (2) explore three hypothesized pathways of transmission: parenting, daily routines, stressors, and supports; and (3) explore the extent to which genotypic variation in candidate genes related to caregiving and stress contribute to caregivers' and children's susceptibility to the effects of early childhood experiences (i.e., gene × environment interactions). We expect that findings from this study will provide critical data needed to identify targets for precision health interventions, reduce health disparities related to toxic stress, and prevent cycles of adversity among families at risk.

Parenting experiences and outcomes among former adolescent mothers: A mixed methods study

The purpose of this explanatory sequential mixed methods study was to examine parenting outcomes and experiences over time among marginalized adolescent mothers enrolled in randomized clinical trials (RCT) between 2002 and 2016 testing Minding the Baby® (MTB), an early home visiting program. The quantitative phase examined associations between measures of maternal experiences and parenting outcomes from 71 participants 2-8 years since RCT completion. MTB mothers reported less hostile parenting and fewer child behavior problems. The sequential qualitative phase involved interviews with a subsample (n = 31) and revealed six themes about their personal and parenting maturation. Through integration of quantitative and qualitative data, we generated metainferences, revealing a nuanced understanding of participants' experiences. Integrated findings revealed the complex personal and parenting experiences among former adolescent mothers during their developmental phases of emerging and early adulthood. Findings inform clinical and research approaches to promote personal growth and positive parenting outcomes over time among women who began childbearing in adolescence.

Safe haven in adolescence: Improving parental reflective functioning and youth attachment and mental health with the Connecting and Reflecting Experience

Attachment security provides a well-documented protective developmental function for children exposed to individual- and community-level trauma, yet the effectiveness of prevention and intervention efforts targeting attachment during adolescence has been relatively underexplored. The Connecting and Reflecting Experience (CARE) program is a transdiagnostic, bi-generational, group-based, mentalizing-focused parenting intervention developed to dismantle the intergenerational transmission of trauma and support secure attachment relationships across the developmental spectrum within an under-resourced community. This exploratory study evaluated outcomes among caregiver-adolescent dyads (N = 32) in the CARE condition of a nonrandomized clinical trial at an outpatient mental health clinic within a diverse, urban U.S. community with disproportionate trauma exposure exacerbated by COVID-19. Caregivers predominantly identified as Black/African/African American (47%), Hispanic/Latina (38%), and/or White (19%). At pre- and post-intervention, caregivers completed questionnaires regarding parental mentalizing and their adolescents' psychosocial functioning. Adolescents completed scales regarding attachment and psychosocial functioning. Results showed a significant decrease in caregivers' prementalizing on the Parental Reflective Functioning Questionnaire, improvement in adolescent psychosocial functioning on the Youth Outcomes Questionnaire, and an increase in adolescents' reports of attachment security on the Security Scale. These preliminary findings suggest that mentalizing-focused parenting interventions may be effective in fostering improved attachment security and psychosocial functioning during adolescence.

Definitions, theories, and measurement of stress in children

PROBLEM

Stress in children remains a complex concept to examine due to the inherent subjectivity and lack of specific manifestations, as well as the multiple ways stress can be defined and measured in children. Because stress is multifactorial,is experienced daily by children, and undergirds adolescent health and early mental illness, it is crucial to have a clear understanding of stress and the effects of stress in children from infancy through age twelve years.

ELIGIBILITY CRITERIA

To be included in this review, literature must pertain to and highlight theories, definitions/classifications, and measurements of stress in children from infancy to 12 years of age.

SAMPLE

The most pertinent articles identified through database searches (PubMed, Scopus, PsycINFO, CINAHL, Google Scholar), gray literature sources (e.g., child health websites), and reference lists of identified articles were included in this narrative overview.

RESULTS

The results of this review are organized by themes and include: classifications and definitions of stress, stress-related theories, and tools to measure stress in children.

CONCLUSIONS

Research addressing stressors and stress in children is limited, and there is wide variation in how researchers define and classify stress in children. Existing measures of stress in children younger than 12 address physiological, psychological, and observational components, but may be inconsistent and threaten validity of otherwise well-designed and well-executed studies.

IMPLICATIONS

Improving the understanding and accurate measurement of stress in children enables researchers and clinicians to curtail undesirable health outcomes.

Cross-sectional relation of long-term glucocorticoids in hair with anthropometric measurements and their possible determinants: A systematic review and meta-analysis

BACKGROUND

Long-term glucocorticoids (HairGC) measured in scalp hair have been associated with body mass index (BMI), waist circumference (WC), and waist-hip-ratio (WHR) in several cross-sectional studies. We aimed to investigate the magnitude, strength, and clinical relevance of these relations across all ages.

METHODS

We performed a systematic review and meta-analysis (PROSPERO registration CRD42020205187) searching for articles relating HairGC to measures of obesity. Main outcomes were bivariate correlation coefficients and unadjusted simple linear regression coefficients relating hair cortisol (HairF) and hair cortisone (HairE) to BMI, WC, and WHR.

RESULTS

We included k = 146 cohorts (n = 34,342 individuals). HairGC were positively related to all anthropometric measurements. The strongest correlation and largest effect size were seen for HairE-WC: pooled correlation 0.18 (95%CI 0.11-0.24; k = 7; n = 3,158; I²  = 45.7%) and pooled regression coefficient 11.0 cm increase in WC per point increase in 10-log-transformed HairE (pg/mg) on liquid-chromatography-(tandem) mass spectrometry (LC-MS) (95%CI 10.1-11.9 cm; k = 6; n = 3,102). Pooled correlation for HairF-BMI was 0.10 (95%CI 0.08-0.13; k = 122; n = 26,527; I²  = 51.2%) and pooled regression coefficient 0.049 kg/m² per point increase in 10-log-transformed HairF (pg/mg) on LC-MS (95%CI 0.045-0.054 kg/m² ; k = 26; n = 11,635).

DISCUSSION

There is a consistent positive association between HairGC and BMI, WC, and WHR, most prominently and clinically relevant for HairE-WC. These findings overall suggest an altered setpoint of the hypothalamic-pituitary-adrenal axis with increasing central adiposity.

An Examination of the Components of Toxic Stress in Childhood and Biological Markers of Physical Health in Emerging Adulthood

Experiencing severe and enduring adversity in childhood without the support of adult figures has been linked to an extensive list of physical health outcomes. This finding is closely tied to the concept of toxic stress, which is regularly studied using a combination of sources, including childhood adversity, unmet basic needs, and unmet social needs. Despite these findings, previous work has typically compiled various sources associated with toxic stress into a single construct, limiting existing knowledge on the contribution of each individual source to physical health. To address these concerns, the current study utilizes data from the National Longitudinal Study of Adolescent to Adult Health to examine the association between independent and collective sources of toxic stress in childhood and individual differences in biomarkers tapping cardiometabolic functioning in emerging adulthood. Results indicate a significant association between a composite measure of sources of toxic stress and cardiometabolic risk, with subsequent models examining the independent influence of each source revealing that this association was largely driven by childhood adversity and unmet basic needs, but not unmet social needs. These findings suggest that the individual sources of toxic stress may differentially contribute to physical health outcomes.

School age effects of Minding the Baby-An attachment-based home-visiting intervention-On parenting and child behaviors

Multiple interventions have been developed to improve the caregiver-child relationship as a buffer to the effects of early life adversity and toxic stress. However, relatively few studies have evaluated the long-term effects of these early childhood interventions, particularly on parenting and childhood behaviors. Here we describe the early school-age follow-up results of a randomized controlled trial of Minding the Baby ® (MTB), a reflective, attachment-based, trauma-informed, preventive home-visiting intervention for first-time mothers and their infants. Results indicate that mothers who participated in MTB are less likely to show impaired mentalizing compared to control mothers two to eight years after the intervention ended. Additionally, MTB mothers have lower levels of hostile and coercive parenting, and their children have lower total and externalizing problem behavior scores when compared to controls at follow-up. We discuss our findings in terms of their contribution to understanding the long-term parenting and childhood socio-emotional developmental effects of early preventive interventions for stressed populations.

Mediation of Mothers' Anxiety and Parenting in Children's Behavior Problems during COVID-19

The outbreak of COVID-19 is affecting the lives of millions of families around the world. The current study was carried out in Israel, following the pandemic's initial outbreak and during the resulting enforced quarantine, confining parents and children to their homes. A sample of 141 Israeli mothers with at least one child between the ages of 3 and 12 (M = 6.92, SD = 2.55) participated as volunteers. About half the sample (50.7%) consisted of girls. Most mothers were cohabiting with a spouse (93%). Mothers completed online questionnaires about their perceptions about the health and economic threats of COVID-19, availability of social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and their children's behavior problems. Results showed expected significant associations between the mothers' reports about having little social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and children's externalizing problems. Likewise, expected significant associations were found between mothers' perceptions about the health and economic threats of COVID-19, their anxiety symptoms, hostile/coercive parenting behavior, and children's internalizing and externalizing problems. Importantly, maternal anxiety and hostile/coercive parenting behavior mediated the associations between lack of support, negative perceptions about the health and economic threats of COVID-19, and children's behavior problems. These findings stress the importance of mothers' mental health and parenting behaviors for children's socioemotional adaptation in the context of COVID-19. Implications of the findings for family interventions intended to help parents and children at this time are suggested.
