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.

Leveraging biosocial methods to examine and address structural determinants of health and promote health equity.

BACKGROUND: Biosocial approaches in nursing research have largely focused on the ways that social determinants of health influence individual-level outcomes, including symptom management, family and social support, and educational interventions. PURPOSE: Theoretical, methodological, and practical strategies are needed to expand current biosocial methods for nursing science and focus on upstream, structural determinants of health and the policies that underlie health inequities. METHODS: This paper summarizes presentations given at the 2023 Council for the Advancement of Nursing Science Advanced Methods Conference, Biosocial Methods to Advance Health Equity, in a panel titled "Individual, community, systems and policy related to biosocial methods." DISCUSSION: Nurses are uniquely positioned to examine upstream, structural determinants of health by leveraging expertise in biosocial methods, collaborating with interdisciplinary researchers and community members, and advocating for policy change. By conducting theory-grounded biosocial research, nurse researchers can significantly advance scientific knowledge and promote health equity for individuals and communities. CONCLUSION: Nurse scientists are conducting research using biosocial methods and provide recommendations for expansion of this approach in the field.

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.

Diaper Need as a Measure of Material Hardship During COVID-19.

BACKGROUND: Diaper need is a lack of reliable access to a sufficient quantity of diaper supplies. It is an essential pediatric social determinant of health measure that is useful for exploring the effects of the COVID-19 pandemic on families of young children. OBJECTIVE: This study aimed to identify the predictors of diaper need and the associations between diaper need and psychosocial outcomes among underresourced families with neurodiverse children. METHODS: This cross-sectional study included 129 caregivers of children aged 0-36 months who completed an online survey in early 2021, during the height of the COVID-19 pandemic. Participants completed a diaper need assessment, the Hunger Vital Signs Food Insecurity Screener, the Perceived Stress Scale, and the Infant Behavioral Questionnaire subscale. Relationships were explored using independent-samples t-tests, chi-square tests, and multiple regression analyses. RESULTS: Seventy-six percent of caregivers reported some diaper need, and 87.6% reported food insecurity. Greater than one third (39.5%) reported high diaper need. Common mitigation strategies included using a towel or other cloth like a diaper, not using a diaper, and keeping the child in the same diaper for longer than usual. In multivariate modeling, food insecurity, household size, and parent age were significantly associated with high diaper need. Families experiencing food insecurity were 4.24 times more likely to experience high diaper need than food-secure families. High diaper need compared to low or no diaper need was associated with increased parent perceived stress. DISCUSSION: We found high levels of diaper need and food insecurity for families during the COVID-19 pandemic. The association of high diaper need and stress indicates an inadequate supply of diapers adversely affects parent stress. Nurses may consider including diaper need in social determinants of health screening and prioritize connecting families to appropriate resources.

Birth-Related Outcomes for Second Children Following Home Visiting Program Enrollment for New Parents of First Children.

INTRODUCTION: Home visiting (HV) programs aim to promote child and family health through perinatal intervention. HV may benefit second children through improving subsequent pregnancy and birth outcomes. However, HV impacts on birth outcomes of second children have not been examined in a naturalistic setting. METHODS: Using data from Connecticut Nurturing Families Network (NFN) home visiting program of families enrolled from 2005 to 2015, we compared birth-related outcomes (birthweight, preterm birth, Cesarean section delivery, prenatal care utilization) of second children (n = 1758) to demographically similar propensity-score-matched families that were not enrolled in NFN (n = 5200). We examined whether the effects of NFN differed by maternal age, race and ethnicity, or visit attendance pattern. RESULTS: There was no program effect for the full sample. The effect of NFN did not differ by maternal age or visit attendance pattern but did differ by maternal race and ethnicity. Black women in NFN were more likely to receive adequate prenatal care during their second pregnancy (OR 1.05; 95% CI 1.01, 1.09) and Hispanic women in NFN were less likely to deliver by Cesarean section for their second birth (OR 0.97; 95% CI 0.94, 0.99), compared to Black and Hispanic women in the comparison group respectively. There was a protective program effect on prematurity of the second child (OR 0.92; 95% CI 0.85, 0.996) for women with a preterm first birth. DISCUSSION: These findings suggest that benefits of HV extend to subsequent birth-related outcomes for women from marginalized racial/ethnic groups. HV may help buffer some harmful social determinants of health.

Using probabilistic record linkage and propensity-score matching to identify a community-based comparison population.

In retrospective cohort studies of interventions disseminated to communities, it is challenging to find comparison groups with high-quality data for evaluation. We present one methodological approach as part of our study of birth outcomes of second-born children in a home visiting (HV) program targeting first-time mothers. We used probabilistic record linkage to link Connecticut's Nurturing Families Network (NFN) HV program and birth-certificate data for children born from 2005 to 2015. We identified two potential comparison groups: a propensity-score-matched group from the remaining birth certificate sample and eligible-but-unenrolled families. An analysis of interpregnancy interval (IPI) is presented to exemplify the approach. We identified the birth certificates of 4822 NFN families. The propensity-score-matched group had 14,219 families (3-to-1 matching) and we identified 1101 eligible-but-unenrolled families. Covariates were well balanced for the propensity-score-matched group, but poorly balanced for the eligible-but-unenrolled group. No program effect on IPI was found. By combining propensity-score matching and probabilistic record linkage, we were able to retrospectively identify relatively large comparison groups for quasi-experimental research. Using birth certificate data, we accessed outcomes for all of these individuals from a single data source. Multiple comparison groups allow us to confirm findings when each method has some limitations. Other researchers seeking community-based comparison groups could consider a similar approach.

The Association Between Neighborhood Social Vulnerability and Cardiovascular Health Risk Among Black/African American Women in the InterGEN Study.

BACKGROUND: Black/African American women in the United States are more likely to live in neighborhoods with higher social vulnerability than other racial/ethnic groups, even when adjusting for personal income. Social vulnerability, defined as the degree to which the social conditions of a community affect its ability to prevent loss and suffering in the event of disaster, has been used in research as an objective measure of neighborhood social vulnerability. Black/African American women also have the highest rates of hypertension and obesity in the United States. OBJECTIVES: The purpose of this study was to examine the relationship between neighborhood social vulnerability and cardiovascular risk (hypertension and obesity) among Black/African American women. METHODS: We conducted a secondary analysis of data from the InterGEN Study that enrolled Black/African American women in the Northeast United States. Participants' addresses were geocoded to ascertain neighborhood vulnerability using the Centers for Disease Control and Prevention's Social Vulnerability Index at the census tract level. We used multivariable regression models to examine associations between objective measures of neighborhood quality and indicators of structural racism and systolic and diastolic blood pressure and obesity (body mass index > 24.9) and to test psychological stress, coping, and depression as potential moderators of these relationships. RESULTS: Seventy-four percent of participating Black/African American women lived in neighborhoods in the top quartile for social vulnerability nationally. Women living in the top 10% of most socially vulnerable neighborhoods in our sample had more than a threefold greater likelihood of hypertension when compared to those living in less vulnerable neighborhoods. Objective neighborhood measures of structural racism (percentage of poverty, percentage of unemployment, percentage of residents >25 years old without a high school diploma, and percentage of residents without access to a vehicle) were significantly associated with elevated diastolic blood pressure and obesity in adjusted models. Psychological stress had a significant moderating effect on the associations between neighborhood vulnerability and cardiovascular risk. DISCUSSION: We identified important associations between structural racism, the neighborhood environment, and cardiovascular health among Black/African American women. These findings add to a critical body of evidence documenting the role of structural racism in perpetuating health inequities and highlight the need for a multifaceted approach to policy, research, and interventions to address racial health inequities.

Maternal Experiences of Racial Discrimination, Child Indicators of Toxic Stress, and the Minding the Baby Early Home Visiting Intervention.

BACKGROUND: Racism is a significant source of toxic stress and a root cause of health inequities. Emerging evidence suggests that exposure to vicarious racism (i.e., racism experienced by a caregiver) is associated with poor child health and development, but associations with biological indicators of toxic stress have not been well studied. It is also unknown whether two-generation interventions, such as early home visiting programs, may help to mitigate the harmful effects of vicarious racism. OBJECTIVE: The purpose of this study was to examine associations between maternal experiences of racial discrimination and child indicators of toxic stress and to test whether relationships are moderated by prior participation in Minding the Baby (MTB), an attachment-based early home visiting intervention. METHODS: Ninety-seven maternal-child dyads (n = 43 intervention dyads, n = 54 control dyads) enrolled in the MTB Early School Age follow-up study. Mothers reported on racial discrimination using the Experiences of Discrimination Scale. Child indicators of toxic stress included salivary biomarkers of inflammation (e.g., C-reactive protein, panel of pro-inflammatory cytokines), body mass index, and maternally reported child behavioral problems. We used linear regression to examine associations between maternal experiences of racial discrimination and child indicators of toxic stress and included an interaction term between experiences of discrimination and MTB group assignment (intervention vs. control) to test moderating effects of the MTB intervention. RESULTS: Mothers identified as Black/African American (33%) and Hispanic/Latina (64%). In adjusted models, maternal experiences of racial discrimination were associated with elevated salivary interleukin-6 and tumor necrosis factor-α levels in children, but not child body mass index or behavior. Prior participation in the MTB intervention moderated the relationship between maternal experiences of discrimination and child interleukin-6 levels. DISCUSSION: Results of this study suggest that racism may contribute to the biological embedding of early adversity through influences on inflammation, but additional research with serum markers is needed to better understand this relationship. Improved understanding of the relationships among vicarious racism, protective factors, and childhood toxic stress is necessary to inform family and systemic-level intervention.

Acceptability and Feasibility of Hair and Salivary Biomarker Collection Among Multiethnic School-Age Children.

OBJECTIVE: As noninvasive biological markers gain increasing popularity in pediatric research, it is critical to understand how study participants perceive these measures, especially among groups underrepresented in biobehavioral research, like children and people of color. The purpose of this study was to examine acceptability and feasibility of hair and salivary biomarker collection in an urban community sample of ethnically diverse children (age 4 to 10 years). METHODS: Ninety-seven mother-child dyads were recruited for a cross-sectional follow up study of the Minding the Baby® home visiting intervention. Children were Hispanic (63%), Black (34%), and multi-racial (3.1%). A conventional content analysis was conducted using two sources of data: (1) mothers' responses to open-ended interview questions on their views and suggestions regarding biomarker collection, and (2) field notes recorded by investigators. RESULTS: Forty-four percent of mothers reported biomarker-related questions or concerns, including questions about the purpose of biomarker testing, and concerns about cosmetic issues, child discomfort, and future use of biomarker data. Mothers also offered positive feedback and advice for collection. Issues affecting feasibility included children's hair length and style, refusal to participate, and behavioral or developmental issues. CONCLUSIONS: Hair and salivary biomarker collection was largely acceptable and feasible in this sample. Strategies for promoting ethical and sensitive biomarker collection include respectful explanations and parental involvement, creating a comfortable and safe environment for the child, flexible collection strategies, and attention to development, cultural preferences and perspectives.

Parenting Among Mothers Who Experienced Child Sexual Abuse: A Qualitative Systematic Review.

Child sexual abuse (CSA) represents a significant public health problem. While CSA is associated with several adverse outcomes, recent attention has been given to its effect on maternal parenting. Despite a growing literature on this topic, a comprehensive systematic review has not been conducted. Thus, this review aimed to fill this gap. Several search strategies were used, including searches in academic databases. Two reviewers completed screening, full-text review, data extraction, and quality determinations. Extracted qualitative data were synthesized for the 108 studies meeting inclusion criteria. The primary themes emerging from women's accounts of the effects of CSA on their current parenting included abuse of child, breastfeeding, child-rearing practices, coping related to parenting, mother-child relationship, perceptions of child, perceptions of motherhood, and protection of children from abuse. Given the current lack of interventions designed for these mothers, the results of this review may aid in the development of evidence-based interventions.

Maternal Adverse Childhood Experiences, Family Strengths, and Chronic Stress in Children.

BACKGROUND: Researchers have demonstrated that maternal adverse childhood experiences (ACEs), such as abuse and neglect, are associated with prenatal risk factors and poor infant development. However, associations with child physiologic and health outcomes, including biomarkers of chronic or "toxic" stress, have not yet been explored. OBJECTIVES: The purpose of this study was to examine the associations among past maternal experiences, current maternal posttraumatic stress disorder (PTSD) symptoms, and children's indicators of exposure to chronic stress in a multiethnic sample of mothers and children at early school age (4 to 9 years). METHODS: This cross-sectional study included maternal-child dyads (N = 54) recruited from urban community health centers in New Haven, Connecticut. Mothers reported history of ACEs, family strengths, and current PTSD symptoms. Child measures included biomarkers and health and developmental outcomes associated with chronic stress. Correlational and regression analyses were conducted. RESULTS: Childhood trauma in mothers was associated with higher systolic blood pressure percentile (ρ = .29, p = .03) and behavioral problems (ρ = .47, p = .001) in children, while maternal history of family strengths was associated with lower salivary interleukin (IL)-1ß (ρ = -.27, p = .055), salivary IL-6 (ρ = -.27, p = .054), and body mass index z-scores (ρ = -.29, p = .03) in children. Maternal PTSD symptoms were associated with more child behavioral problems (ρ = .57, p < .001) and higher odds of asthma history (ρ = .30, p = .03). DISCUSSION: Results indicate that past maternal experiences may have important influences on a child's health and affect his or her risk for experiencing toxic stress.

Associations Between Maternal Experiences of Discrimination and Biomarkers of Toxic Stress in School-Aged Children.

OBJECTIVE: To examine associations between maternal experiences of discrimination and child biomarkers of toxic stress in a multiethnic, urban sample of mothers and children (4-9 years). METHODS: Data were drawn from a cross-sectional study of maternal-child dyads (N = 54) living in low-income neighborhoods in New Haven, Connecticut, USA. Mothers reported experiences of discrimination. Noninvasive biomarkers of toxic stress were collected to assess neuroendocrine (hair cortisol), immune (salivary cytokines, c-reactive protein), and cardiovascular (blood pressure) functioning in children. RESULTS: Maternal experiences of discrimination were associated with increased log-transformed salivary interleukin-6 (IL-6) levels in children (ß = 0.15, p = 0.02). CONCLUSIONS: Vicarious racism, or indirect exposure to discrimination experienced by caregivers, is associated with poor health outcomes for children. Immune pathways may be a biological mechanism through which racial discrimination "gets under the skin," but additional research is needed to fully understand these relationships. Uncovering the physiological mechanisms linking vicarious racism with child health is an important step towards understanding possible early roots of racial and ethnic health inequities.

Birth outcomes of second children after community-based home visiting: A research protocol.

Birth-related outcomes, such as birth weight, have lifelong impacts on health. Home visiting (HV) is an established approach to improve the health of children and families, parenting practices, and connections to social and health services. Many HV programs target first-time mothers, in part because HV activities related to a first-birth may improve birth outcomes for subsequent children, but few researchers have examined these effects. We will link data from a statewide HV program (Nurturing Families Network [NFN]) to birth certificate data to create comparison groups and measure outcomes in this observational study. Specifically, we will compare birth outcomes for NFN second-children (n = 3000) to those for: (a) first-child older siblings whose birth/gestation led to NFN enrollment (n = 3000); (b) second children of families who were screened as eligible for NFN, but not offered the program due to home visitor availability and other logistical reasons (n = 650); and (c) non-NFN second children in a propensity-score-matched group created using the likelihood of enrollment in NFN based on maternal health, demographics, and neighborhood characteristics (n = 6000). The outcomes we will examine are birth spacing, prenatal care received, cesarean section rate, gestational age, and birth weight in second-children. We will also examine the associations between program attendance (i.e., missed visits, dropout) and birth outcomes, that will generate evidence that may be used in programmatic decisions regarding continued funding and/or modification of NFN, prioritization of specific retention efforts, and targeting of first-time mothers. Use of this evidence should improve outcomes for future NFN families and may inform similar programs.

Maternal, Infant, and Early Childhood Home Visiting: A Call for a Paradigm Shift in States' Approaches to Funding.

Early home visiting is a vital health promotion strategy that is widely associated with positive outcomes for vulnerable families. To expand access to these services, the Maternal, Infant, and Early Childhood Home Visiting (MIECHV) program was established under the Affordable Care Act, and over $2 billion have been distributed from the Health Resources and Services Administration to states, territories, and tribal entities to support funding for early home visiting programs serving pregnant women and families with young children (birth to 5 years of age). As of October 2018, 20 programs met Department of Health and Human Services criteria for evidence of effectiveness and were approved to receive MIECHV funding. However, the same few eligible programs receive MIECHV funding in almost all states, likely due to previously established infrastructure prior to establishment of the MIECHV program. Fully capitalizing on this federal investment will require all state policymakers and bureaucrats to reevaluate services currently offered and systematically and transparently develop a menu of home visiting services that will best match the specific needs of the vulnerable families in their communities. Federal incentives and strategies may also improve states' abilities to successfully implement a comprehensive and diverse menu of home visiting service options. By offering a menu of home visiting program models with varying levels of service delivery, home visitor education backgrounds, and targeted domains for improvement, state agencies serving children and families have an opportunity to expand their reach of services, improve cost-effectiveness, and promote optimal outcomes for vulnerable families. Nurses and nursing organizations can play a key role in advocating for this approach.

Toxic stress and protective factors in multi-ethnic school age children: A research protocol.

Exposure to stressful environments in early childhood can cause a toxic stress response and lead to poor health outcomes, including obesity, cardiac disease, diabetes, and mental illness. In animals and maltreated children, the presence of a nurturing caregiver can buffer against the physiological disruptions associated with a toxic stress response; however, the specific caregiver and parenting characteristics that best promote a protective relationship in humans remain largely unexplored, particularly in families living in high-risk environments. In this study, framed in an ecobiodevelopmental (EBD) model, a cross-sectional design is being used to study 54 multi-ethnic, urban maternal-child dyads with children at early school age (4-9 years). Mothers' past experiences, mental health, and caregiving patterns and children's hair cortisol, C-reactive protein, pro-inflammatory cytokines, blood pressure, BMI, behavior, and school performance are being analyzed to identify maternal characteristics that may protect against children's toxic stress response in families at high risk for exposure to stressors such as poverty, trauma, or exposure to violence.

A diaper bank and home visiting partnership: Initial exploration of research and policy questions.

OBJECTIVES: The cost of diapering an infant can place a significant financial strain on families living in poverty. Partnerships between diaper banks and home visiting programs for young families may offer an innovative solution to expanding the reach and impact of diaper banks in low-income communities. The purpose of this pilot study was to uncover preliminary information about the functions of diaper distribution through home visiting programs, and to inform future research and policy questions regarding diaper distribution to families in need. DESIGN AND SAMPLE: In this descriptive qualitative pilot study, semi-structured interviews were conducted with 6 home visitors from Minding the Baby® (MTB), a home visiting intervention for young parents. MTB clinicians routinely distribute diapers in partnership with The Diaper Bank in Connecticut. We used directed content analysis to code and analyze interview transcripts. RESULTS/CONCLUSION: These preliminary findings indicate that partnerships between home visiting programs and diaper banks may benefit families by improving diaper access, reducing stigma, and fostering trusting relationships with home visitors. Home visiting program benefits including engagement or re-engagement with families may need to be balanced with potential effects on clinical and therapeutic relationships. Recommendations for next steps in research and related policy questions are discussed.

Psychosocial Influences on Acceptability and Feasibility of Salivary Cortisol Collection From Community Samples of Children.

Salivary cortisol is considered to be a safe and noninvasive measure of hypothalamic-pituitary-adrenal axis functioning, and is a commonly measured biomarker of the human stress response in pediatric research. However, cortisol is highly variable and sensitive to a wide range of factors, creating a challenge for reliable salivary cortisol collection in the community setting. Furthermore, the acceptability of salivary cortisol collection in community samples of children is largely unknown. The purpose of this integrative review was to investigate current evidence on the acceptability and feasibility of salivary cortisol collection in community samples of children. In an analysis framed by the Theory of Planned Behavior, data extracted from 31 studies revealed six categories of psychosocial influences on acceptability and feasibility: uncertainty and misconceptions, cultural and ethnic values, family rules and values, difficulty following protocols and procedures, burden of multiple samples, and child refusal or resistance. Further research is required to fully understand the factors that influence acceptability and feasibility of salivary cortisol collection in community samples of children. Understanding individual, family, and community perceptions of biobehavioral research will lead to more culturally sensitive and feasible community-based research methods. © 2016 Wiley Periodicals, Inc.

Social determinants of inflammatory markers linking depression and type 2 diabetes among women: A scoping review.

OBJECTIVE: Inflammation is implicated in the pathophysiology of depression and type 2 diabetes (T2D) and is linked to social determinants of health (SDoH) associated with socioeconomic disadvantage. The objective of this review is to identify and map the range of SDoHs associated with inflammation in depression, T2D, or their co-occurrence among women. METHODS: PubMed, CINAHL, PsychINFO, and Web of Science were searched March-July 2023 to identify studies where 1) an SDoH was a predictor or independent variable, 2) depression or T2D was a clinical focus, 3) inflammatory markers were collected, and 4) analysis was specific to women. We used the National Institute on Minority Health and Health Disparities research framework to guide searching SDoHs, organize findings, and identify gaps. RESULTS: Of the 1135 studies retrieved, 46 met criteria. Within the reviewed studies, the most used inflammatory measures were C-reactive protein, interleukin-6, and tumor necrosis factor-α, and the most studied SDoHs were early life stress and socioeconomic status. Individual and interpersonal-level variables comprised the bulk of SDoHs in the included studies, while few to no studies examined built environment (n = 6) or health system level (n = 0) factors. Disadvantageous SDoHs were associated with higher levels of inflammation across the included studies. CONCLUSION: The scope and intersection of depression and T2D represent a syndemic that contributes to and results from socioeconomic inequities and disproportionately affects women. Simultaneous inclusion of social and inflammatory measures, particularly understudied SDoHs, is needed to clarify potent targets aimed at advancing health and equity.

Participation in an Attachment-Based Home Visiting Program Is Associated with Lower Child Salivary C-Reactive Protein Levels at Follow-Up.

OBJECTIVE: Exposure to early childhood adversity is associated with an increased risk for physiological disruption, including increased inflammation. Early interventions that support the mother-child relationship have been shown to potentially buffer negative psychosocial outcomes related to early adversity, but it is unclear whether these interventions have long-term biological effects. We evaluated whether prior participation in Minding the Baby® (MTB), an attachment-based home visiting intervention for young mother-infant dyads living in underserved communities, is associated with lower child salivary inflammatory biomarkers compared with controls at follow-up. METHODS: Ninety-seven maternal-child dyads (n = 43 intervention and n = 54 controls) enrolled in a follow-up study of the MTB randomized controlled trial, an average of 4.6 years after RCT completion. Children provided salivary specimens. We used adjusted linear regression to examine the relationship between MTB participation and child salivary inflammatory biomarkers (C-reactive protein [CRP], interleukin [IL]-1ß, IL-6, IL-8, and TNF-α). RESULTS: Children were on average 6.6 years old, 48% female, and identified as non-Hispanic/Latino Black/African American (34%) and Hispanic/Latino (63%). Participation in MTB was associated with lower salivary CRP levels (ß = -0.31, SE = 0.28, p = 0.003) compared with controls. Participation in MTB was not associated with salivary cytokine levels. DISCUSSION: Participation in an intensive two-generation home visiting intervention such as MTB may reduce salivary inflammatory biomarkers associated with early childhood adversity. Replication and further research are needed to improve the understanding of the potential for early childhood interventions to buffer the biological embedding of early adversity.
