Brief Summary:
Aim 1 To characterize allostatic load AL biomarkers in a sample of low-income early adolescents N 225 How many children living in low-income homes have atypical or out-of-range biomarker levels on which biomarkers and in what combinations Aim 1a Do AL biomarker elevations predict physical and mental health problems in early adolescence Aim 1b How much and what type of change in AL biomarkers occurs between ages 11 and 14 Aim 1c
Aim 2 To investigate in the same sample of early adolescents exposed to varying levels of early life stress ELS the relative contributions made by ELS recent past year and cumulative since age 5 stress exposures to initial AL levels at T1 Aim 2a and to changes in AL across the two years of the study Aim 2b
Aim 3 To explore the extent to which coping resources including childrens coping skills childrens physiologic self-regulation and parental coping socialization uniquely and synergistically influence AL levels and accumulations in these early adolescents

Detailed Description:
Childhood adversity is associated with premature diseases of aging most forms of psychopathology and early mortality and chronic stress is a critical mechanism of this phenomenon Biologically informed interventions are sorely needed to break this pernicious cycle but very little research has examined potentially malleable psychobiological risk and protective processes during childhood that could be leveraged in interventions Allostatic Load AL-the accumulation of biological insults sustained by the bodys attempts to maintain homeostasis in the face of chronic stress-is recognized as one such risk process Most AL research has thus far been conducted with adults but the emerging research with adolescents suggests that in-depth examination of AL accumulation processes during early adolescence may yield critical insights needed to develop psychobiologically potent interventions Coping and self-regulation are potential malleable protective processes but they have not received much attention in AL research to date This R01 project will therefore examine the accumulation of AL biomarkers in early adolescence and will test the contributions of stress early life cumulative recent and of coping resources coping skills parent coping socialization physiologic regulation to AL accumulation In addition we will examine associations between AL and the emergence of premature diseases of aging eg type II diabetes metabolic syndrome by mid-adolescence
Elevated AL biomarkers have been detected in samples of disadvantaged preadolescents eg Evans 2003 Keller et al 2012 Rogosch et al 2011 and are correlated with health problems in this population Nevertheless numerous important gaps in our understanding of youth AL processes remain First AL is not well characterized in child or adolescent samples Most existing research involving children focuses only on select aspects of the AL index such as cortisol and a comprehensive assessment of the major classes of biomarkers indicated in AL metabolic cardiovascular immunologic neuroendocrine in at-risk children is lacking Second the absence of clinical benchmarks linking AL to disease in children is a major limiting factor which coupled with lower base rates of AL-linked diseases in children calls into question the typical practice of calculating an AL index using adult thresholds ie upper quartile of range Third it is unclear to what extent recent and cumulative stressors experienced after the early life period birth to age 5 contribute to the development of AL over and above early life stress ELS in any age group and many AL studies do not include in-depth assessments of life stress Fourth little is known about the extent to which coping resources youth coping skills coping socialization can buffer children from the development andor worsening of AL over time This is a critical question as the lead PIs research has shown that coping skills and resources can buffer at-risk children eg in poverty from common stressors and that coping has effects on primary neuroendocrine mediators of AL such as the HPA Wadsworth et al 2016 Bendezu Wadsworth 2017
The present project will build on the unique strengths and capacities of the two PIs and their co-investigator and will include state-of-the-art assessments of stress coping resources and AL to fully capture these processes at multiple levels of analysis Two-hundred 11-12 year old Medicaid-enrolled patients will be recruited by experienced pediatric research nurses at Penn State Hershey Hope Drive Pediatrics Twenty-five additional 11-12 year old patients whose families are not Medicaid eligible will serve as a middle class comparison group for biomarker benchmarking This research affiliated pediatrics practice conducts 40000 patient visits per year and enrolls patients from both rural and urban communities across central PA Youth will be followed across two years and participate in three annual assessments Biological samples will include blood draws overnight urine and saliva samples taken at each time point Assessments will further include a parent and child Youth Life Stress Interviews to obtain indices of early recent and cumulative life stress and b the Trier Social Stress Test to measure adolescent SAM and HPA activation patterns and parent coping socialization Parent-child parasympathetic co-regulation and reports of psychological symptoms parenting parent-child attachment and coping skills will also be obtained We will examine levels and correlates of AL biomarkers at T1 as well as predictors of the changes that occur between T1 T2 and T3 AL accumulation Study aims are as follows
Aim 1 To characterize AL biomarkers in a sample of low-income preadolescents N 200 How many children living in low-income homes have atypical or out-of-range biomarker levels as compared to middle class comparison group Aim 1a Do prior AL biomarker elevations predict physical and mental health problems at age 13-14 Aim 1b How much and what type of change in AL biomarkers occurs between ages 11 and 14 Aim 1c
Aim 2 To investigate in the same sample of preadolescents exposed to varying levels of ELS the relative contributions made by ELS recent past year and cumulative since age 5 stress exposures to initial AL levels at T1 Aim 2a and to changes in AL across the two years of the study Aim 2b
Aim 3 To examine how coping resources including childrens coping skills childrens physiologic self-regulation parent-child attachment and parent coping socialization uniquely and synergistically influence AL levels and accumulations in early adolescence
