Examining Parent Adverse Childhood Experiences as a Distal Risk Factor in Pediatric Chronic Pain

Interpersonal dyadic influences on transitions between pain states: a narrative review and synthesis

ABSTRACT

Pain is not experienced in isolation; it is affected by and affects other people. Interactions between parents and partners and people living with pain affect beliefs, emotions and behaviours, and pain progress and change. We searched systematically for longitudinal studies of associations between specific familial, dyadic, interpersonal factors and quantitative pain transitions. We coded studies for risk of bias. For the narrative synthesis, we grouped findings by dyads-parents and children, and people with pain and their partners (usually spouses), and then by the psychosocial mechanism/s. We described certainty of evidence for each pain transition and each mechanism. Patient and public contributors were involved throughout. Of 52 studies, 38 were of parents and children (27,814 dyads) and 14 of partners (4904 dyads). Three groups of predictive factors were identified for parent and child studies: parent mental health, parent cognitions, and parent behaviours. Parental anxiety (but not depression) predicted children's onset of pain and worsening; the evidence was of moderate certainty and almost exclusively involved mothers. Evidence that some parental behaviours, such as protective behaviours, were associated with worse child pain was of very low certainty. The evidence for partners was of poor quality, precluding synthesis. The review highlights that most interpersonal pain research fails to capture the complex dynamics of longstanding relationships and highlights the difficulty of doing so using simple models.

Examining the epigenetic transmission of risk for chronic pain associated with paternal post-traumatic stress disorder: a focus on veteran populations

Chronic pain is a public health problem that significantly reduces quality of life. Although the aetiology is often unknown, recent evidence suggests that susceptibility can be transmitted intergenerationally, from parent to child. Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder, often associated with chronic pain, that has high prevalence rates in military personnel and Veterans. Therefore, we aimed to characterise the epigenetic mechanisms by which paternal trauma, such as PTSD, is transmitted across generations to confer risk in the next generation, specifically focusing on Veterans where possible. Numerous overlapping neurological pathways are implicated in both PTSD and chronic pain; many of which are susceptible to epigenetic modification, such as DNA methylation, histone modifications, and RNA regulation. Hence, epigenetic changes related to pain perception, inflammation, and neurotransmission may influence an individual's predisposition to chronic pain conditions. We also examine the effects of PTSD on parenting behaviours and discuss how these variations could impact the development of chronic pain in children. We highlight the need for further research regarding the interactions between paternal trauma and epigenetic processes to ultimately generate effective prevention and therapeutic strategies for Veterans who have been affected by PTSD and chronic pain.

A nationwide longitudinal survey of infantile injury and its recurrence in Japan

Injury recurrence in young children is a significant public health concern, as it may indicate an unfavorable home environment. This study evaluates whether infantile injuries increase recurrence during preschool years, contributing to more effective prevention strategies for vulnerable families. The study included 20,191 children from "The Longitudinal Survey of Babies in the 21st Century," a representative sample of infants born in Japan between May 10 and 24, 2010. We conducted a logistic regression analysis to compare injury recurrence risk between children aged 18 months to seven years with and without infantile injury histories. The study revealed that infants with a history of injuries had a higher risk of subsequent hospital visits for injuries during preschool years (crude Odds Ratio (cOR) 1.52, 95% CI, 1.41-1.64, adjusted OR (aOR) 1.48, 95% CI 1.37-1.60). Specific injuries, such as falls (aOR 1.34, 95% CI, 1.26-1.43), pinches (aOR 1.22, 95% CI, 1.15-1.29), drowning (aOR 1.29, 95% CI, 1.19-1.40), ingestion (aOR 1.35, 95% CI, 1.17-1.55), and burns (aOR 1.47, 95% CI, 1.31-1.65), independently increased the risk of future injuries. Our findings highlight the necessity of universal safety measures in the home environment and targeted interventions for families with a history of high-risk injuries.

Parental narrative style moderates the relation between pain-related attention and memory biases in youth with chronic pain

ABSTRACT

Negatively biased pain memories robustly predict maladaptive pain outcomes in children. Both attention bias to pain and parental narrative style have been linked with the development of these negative biases, with previous studies indicating that how parents talk to their child about the pain might buffer the influence of children's attention bias to pain on the development of such negatively biased pain memories. This study investigated the moderating role of parental narrative style in the relation between pain-related attention and memory biases in a pediatric chronic pain sample who underwent a cold pressor task. Participants were 85 youth-parent dyads who reminisced about youth's painful event. Eye-tracking technology was used to assess youth's attention bias to pain information, whereas youth's pain-related memories were elicited 1 month later through telephone interview. Results indicated that a parental narrative style using less repetitive yes-no questions, more emotion words, and less fear words buffered the influence of high levels of youth's attention bias to pain in the development of negatively biased pain memories. Opposite effects were observed for youth with low levels of attention bias to pain. Current findings corroborate earlier results on parental reminiscing in the context of pain (memories) but stress the importance of matching narrative style with child characteristics, such as child attention bias to pain, in the development of negatively biased pain memories. Future avenues for parent-child reminiscing and clinical implications for pediatric chronic pain are discussed.

Critical Windows: Exploring the Association Between Perinatal Trauma, Epigenetics, and Chronic Pain

Chronic pain is highly prevalent and burdensome, affecting millions of people worldwide. Although it emerges at any point in life, it often manifests in adolescence. Given that adolescence is a unique developmental period, additional strains associated with persistent and often idiopathic pain lead to significant long-term consequences. While there is no singular cause for the chronification of pain, epigenetic modifications that lead to neural reorganization may underpin central sensitization and subsequent manifestation of pain hypersensitivity. Epigenetic processes are particularly active during the prenatal and early postnatal years. We demonstrate how exposure to various traumas, such as intimate partner violence while in utero or adverse childhood experiences, can significantly influence epigenetic regulation within the brain and in turn modify pain-related processes. We provide compelling evidence that the burden of chronic pain is likely initiated early in life, often being transmitted from mother to offspring. We also highlight two promising prophylactic strategies, oxytocin administration and probiotic use, that have the potential to attenuate the epigenetic consequences of early adversity. Overall, we advance understanding of the causal relationship between trauma and adolescent chronic pain by highlighting epigenetic mechanisms that underlie this transmission of risk, ultimately informing how to prevent this rising epidemic.

Parent Anxiety, Depression, Protective Responses, and Parenting Stress in the Context of Parent and Child Chronic Pain: A Daily Diary Study of Parent Variability

Parents with (vs without) chronic pain report poorer psychosocial functioning (eg, worse mental health, parenting difficulties), which has been linked to poorer child outcomes (eg, child pain). However, emerging research suggests that individuals vary in their functioning from day-to-day, particularly those with chronic pain. This study used daily diaries to compare parents with (versus without) chronic pain on variability in their anxiety, mood, protective responses, and parenting stress. We also examined parent chronic pain status as a moderator of the associations between parent variability and youth daily pain and interference. Participants were 76 youth with chronic pain (Mage = 14.26; 71.1% female) and one of their parents (89.5% mothers; n = 38 or 50.0% endorsing chronic pain). Parents and youth completed self-report questionnaires and 7 days of diaries. Parent variability was calculated to reflect the frequency and size of day-to-day changes. Multilevel models revealed that parents with (vs without) chronic pain were significantly more variable in their parenting stress, but not in their anxiety, mood, or protective responses. Contrary to hypotheses, parent variability was not significantly related to youth daily pain intensity or interference and parent chronic pain did not moderate any associations. Instead, mean levels of parent anxiety, protective responses, and parenting stress across the week significantly predicted youth daily pain interference. Findings suggest that while variability was observed among parents (with and without chronic pain) of youth with chronic pain, it did not significantly predict youth's daily pain-related functioning. Further research is needed to confirm these initial findings. PERSPECTIVE: Parents with chronic pain have expressed concerns that the variable nature of their pain negatively impacts their children. Our results found that parents (with and without chronic pain) were variable in their anxiety, mood, protective responses, and parenting stress, but this variability did not significantly predict youth's chronic pain-related functioning.

The association between parent mental health and pediatric chronic pain: a systematic review and meta-analysis

ABSTRACT

Mental health problems are common among parents of children with chronic pain and associated with worse outcomes for the child with chronic pain. However, the effect sizes of these associations between parent mental health and pediatric chronic pain vary widely across studies. The aim of this systematic review and meta-analysis was to generate pooled estimates of the (1) prevalence of mental health problems among parents of children with chronic pain and (2) associations between parent mental health and the (2a) presence of child chronic pain and (2b) functioning of children with chronic pain. Embase, MEDLINE, PsycINFO, Web of Science, and CINAHL were searched up to November 2022. Observational studies that examined symptoms or diagnoses of parent anxiety, depression, or general distress and the presence of child chronic pain and/or related functioning were included. From 32,848 records, 2 coders identified 49 studies to include in random-effects meta-analyses. The results revealed that mental health problems among parents of children with chronic pain were common (anxiety: 28.8% [95% CI 20.3-39.1]; depression: 20.0% [15.7-25.2]; general distress: 32.4% [22.7-44.0]). Poorer parent mental health was significantly associated with the presence of chronic pain (anxiety: OR = 1.91 [1.51-2.41]; depression: OR = 1.90 [1.51-2.38]; general distress: OR = 1.74 [1.47-2.05]) and worse related functioning (ie, pain intensity, physical functioning, anxiety and depression symptoms; r s = 0.10-0.25, all P s < 0.05) in children. Moderator analyses were generally nonsignificant or could not be conducted because of insufficient data. Findings support the importance of addressing parent mental health in the prevention and treatment of pediatric chronic pain.

A role for adverse childhood experiences and depression in preeclampsia

Introduction

Adverse childhood experiences (ACEs) are a measure of childhood adversity and are associated with life-long morbidity. The impacts of ACEs on peripartum health including preeclampsia, a common and dangerous hypertensive disorder of pregnancy, remain unclear, however. Therefore, we aimed to determine ACE association with peripartum psychiatric health and prevalence of preeclampsia using a case-control design.

Methods

Clinical data were aggregated and validated using a large, intergenerational knowledgebase developed at our institution. Depression symptoms were measured by standard clinical screeners: the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS). ACEs were assessed via survey. Scores were compared between participants with (N = 32) and without (N = 46) prior preeclampsia.

Results

Participants with ACE scores ≥4 had significantly greater odds of preeclampsia than those with scores ≤ 3 (adjusted odds ratio = 6.71, 95% confidence interval:1.13-40.00; p = 0.037). Subsequent speculative analyses revealed that increased odds of preeclampsia may be driven by increased childhood abuse and neglect dimensions of the ACE score. PHQ-9 scores (3.73 vs. 1.86, p = 0.03), EPDS scores (6.38 vs. 3.71, p = 0.01), and the incidence of depression (37.5% vs. 23.9%, p = 0.05) were significantly higher in participants with a history of preeclampsia versus controls.

Conclusions

Childhood sets the stage for life-long health. Our findings suggest that ACEs may be a risk factor for preeclampsia and depression, uniting the developmental origins of psychiatric and obstetric risk.

Maternal and Paternal Adverse Childhood Experiences (ACEs) and Offspring Health and Wellbeing: A Scoping Review

BACKGROUND

Adverse childhood experiences (ACEs) are common, often co-occur, and are associated with poor health outcomes across the life course. Emerging research has emphasized the lasting consequences of ACEs across generations, suggesting parental ACEs are associated with poor physical and mental health outcomes in children. However, the individual effects of fathers' ACEs and pathways of transmission remain unclear. A scoping review was conducted to summarize the current knowledgebase of the intergenerational consequences of parental ACEs on offspring health, clarify pathways of transmission, understand how ACEs are operationalized in the intergenerational literature, and identify gaps in knowledge.

METHODS

Six electronic databases were searched for articles published in English from 1995 to 2022 relating to the long-term consequences of parental ACEs on offspring physical and mental health. Articles underwent title, abstract, and full-text review by two investigators. Content analysis was performed to integrate findings across the included studies.

RESULTS

The search yielded 14,542 unique articles; 49 met the inclusion criteria. Thirty-six articles focused exclusively on mothers, one solely on fathers, and 12 included both mothers and fathers in their analyses. Six studies used an expanded definition of ACEs. Both direct and indirect associations between parental ACEs and poor offspring outcomes were identified, primarily through biological and psychosocial pathways.

CONCLUSIONS

Findings underscore the importance and oversight of fathers and the need to solidify a unified definition and measure of ACEs. This review identified modifiable protective factors (social support, father involvement) and pathways of transmission (parental mental health, parenting); both having important implications for intervention development.

Intergenerational Transmission of Parental Adverse Childhood Experiences and Children's Outcomes: A Scoping Review

Adverse childhood experiences (ACEs) are among the leading environmental causes of morbidity and mortality. Extending research on within-generation effects, more recent scholarship has explored between-generation consequences of ACEs. Despite growing interest in the intergenerational effects of parents' ACEs on children's outcomes, this line of scholarship has yet to be coalesced into a comprehensive review. The current study is a scoping review on the intergenerational transmission of parental ACEs and children's outcomes. Ten databases such as PubMed, APA PsycArticles, and Social Work Abstracts were searched. To be included, empirical studies must have been published in English and analyzed associations between a cumulative measure of at least four parental ACEs and children's outcomes. Sixty-eight studies qualified for the review and, among these, 60 were published in the most recent 5 years (2018-2022). Fifty-one studies had sample sizes smaller than 500, and 55 focused on the effect of maternal ACEs. Nearly all studies demonstrated that parental ACEs could affect children's outcomes directly or indirectly via mechanisms like maternal mental health problems or parenting-related factors. By scoping the extant literature, this review advances the knowledge base regarding the intergenerational impacts of parental childhood trauma and children's outcomes. It also reveals methodological limitations that should be addressed in future research to strengthen causal inferences along with practical implications for interventions that aim to interrupt the intergenerational transmission of trauma.

Caregiver Psychological Burden in Pediatric Chronic Pain: A Systematic Review and Meta-Analysis of Associations with Caregiver Sociodemographic and Biopsychosocial Variables

OBJECTIVE

To investigate, via systematic review and meta-analysis, caregiver sociodemographic and biopsychosocial factors associated with anxiety, depression, posttraumatic stress symptoms, and stress of caregivers in the pediatric chronic pain context.

METHODS

EMBASE, Medline, and PsycINFO databases were searched from their inception to the search date (April 4, 2022). Studies were included if they examined caregivers of youth with chronic pain, were published in a peer-reviewed journal and assessed at least one quantitative association between relevant variables. Qualitative and intervention studies were excluded. A total of 3,052 articles were screened. Risk of bias was assessed using the JBI Checklist for analytical cross-sectional studies. Meta-analyses were conducted using robust variance estimation for associations reported in at least three studies, as well as a narrative synthesis of the evidence.

RESULTS

Fourteen studies assessing 1,908 caregivers were included in this review. Meta-analytic results showed a positive pooled correlation coefficient between caregiver catastrophizing about their child's pain and caregiver anxiety (r = 0.51; 95% CI: 0.35-0.65; p<.01) and depression (r = 0.45; 95% CI: 0.29-0.58; p < .01). Self-blame and helplessness were related to increased caregiver anxiety (r = 0.55; 95% CI: 0.40-0.67; p<.01), but not depression. No significant relationship was found for pain-promoting behavior and anxiety or depression. The qualitative synthesis of all other eligible studies showed associations between relevant psychological burden variables and various caregiver factors, which were mainly psychosocial.

CONCLUSION

Results should be interpreted with caution due to the small number of studies. Further research is needed to get a better understanding of these relationships and to examine the causal direction of effects.

The relationship between parental adverse childhood experiences and the health, well-being and development outcomes of their children: a systematic review

OBJECTIVES

A growing body of research is emerging regarding the relationship between parental adverse childhood experiences (ACEs) and negative health, well-being and developmental outcomes in their children. This systematic review seeks to understand the relationship between parental ACEs and the health, well-being and developmental outcomes of their children and whether the relationships differ according to the number and type of parental ACEs.

STUDY DESIGN

Systematic review.

METHOD

The review includes articles published between 2000 and 2021 from studies using quantitative longitudinal methods and multivariate analysis to investigate the relationship between parental ACEs and their offspring's outcomes. Relevant studies were identified through a systematic search of five databases and findings synthesised using a narrative synthesis. This review was registered on PROSPERO (CRD42021274068).

RESULTS

Nineteen studies met the inclusion criteria and were included in the review. This resulted in a combined population sample of 124,043 parents and 128,400 children. Diversity in measurement of parental ACE exposure and in the type of ACEs measured within the studies precluded a meta-analysis. Offspring of parents exposed to ACEs had a higher risk of a range of negative health, well-being and developmental outcomes. This relationship differs according to the number and type of parental ACEs, with a positive relationship observed between the number of parental ACEs and the risk of negative health, well-being and development outcomes in their children.

CONCLUSIONS

These findings indicate that screening for parental ACEs by health visitors, midwives and other health or social care staff may identify an at-risk population of infants, children and adolescents and improve child outcomes.

A Pilot Study Investigating the Role of Gender in the Intergenerational Relationships between Gene Expression, Chronic Pain, and Adverse Childhood Experiences in a Clinical Sample of Youth with Chronic Pain

Chronic pain is a highly prevalent and costly issue that often emerges during childhood or adolescence and persists into adulthood. Adverse childhood experiences (ACEs) increase risk for several adverse health conditions, including chronic pain. Recent evidence suggests that parental trauma (ACEs, post-traumatic stress disorder (PTSD) symptoms) confers risk of poor health outcomes in their children. Intergenerational relationships between parental trauma and child chronic pain may be mediated by epigenetic mechanisms. A clinical sample of youth with chronic pain and their parents completed psychometrically sound questionnaires assessing ACEs, PTSD symptoms, and chronic pain, and provided a saliva sample. These were used to investigate the intergenerational relationships between four epigenetic biomarkers (COMT, DRD2, GR, and SERT), trauma, and chronic pain. The results indicated that the significant biomarkers were dependent upon the gender of the child, wherein parental ACEs significantly correlated with changes in DRD2 expression in female children and altered COMT expression in the parents of male children. Additionally, the nature of the ACE (maltreatment vs. household dysfunction) was associated with the specific epigenetic changes. There may be different pathways through which parental ACEs confer risk for poor outcomes for males and females, highlighting the importance of child gender in future investigations.
