Adverse Childhood Experiences and Immune System Inflammation in Adults Residing on the Blackfeet Reservation: The Moderating Role of Sense of Belonging to the Community

Adverse childhood experiences and diet quality in the national sample of poles: The mediating role of emotion regulation

Adverse childhood experiences (ACEs) increase the risk of adverse psychological and physical outcomes and chronic disease in adulthood. The mechanism of this relationship is still unclear. ACEs might exert their negative influence on adult health via both dietary and psychological axes. Our study aimed to examine the relationship between ACEs and diet quality in the national sample of Poles. We also aimed to determine whether difficulty in regulating emotions act as a mediator of this relationship. The national Polish sample of adults (n = 3557) took part in this study. ACEs were assessed via the Adverse Childhood Experiences Questionnaire. Data on food consumption frequency over the past year, body weight and height were collected using the self-administered version of the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN®). Two diet quality scores were evaluated: Pro-Healthy-Diet-Index-10 (pHDI) and Non-Healthy-Diet-Index-14 (nHDI). Emotion regulation (ER) was evaluated via the Difficulties in Emotion Regulation Scale (DERS). Path analysis was used to examine the associations between the variables, firstly formulated by theoretical assumptions expressed by directed acyclic graphs (DAGs). A higher number of ACEs was related to higher difficulties in ER in adults (p < 0.001), which in turn was related to lower pHDI (p < 0.001) and higher nHDI (p = 0.027). Our findings strengthen the rationale for ACEs screening as a potential risk factor for diet-related chronic disease in adulthood. They provide a framework for public health prevention strategies via interventions targeting diet quality and emotional regulation in the setting of multidisciplinary practice.

Inflammation as a mediator between adverse childhood experiences and adult depression: A meta-analytic structural equation model

Exposure to adverse childhood experiences (ACEs) confers a higher risk of developing depression in adulthood, yet the mediation of inflammation remains under debate. To test this model, we conducted a systematic review and two-stage structural equation modelling meta-analysis of studies reporting correlations between ACEs before age 18, inflammatory markers and depression severity in adulthood. Scopus, Pubmed, Medline, PsycInfo, and CINAHL were searched up to 2 October 2023. Twenty-two studies reporting data on C-reactive protein (CRP, n = 12,935), interleukin-6 (IL-6, n = 4108), tumour necrosis factor-α (TNF-α, n = 2256) and composite measures of inflammation (n = 1674) were included. Unadjusted models revealed that CRP (β = 0.003, 95 % LBCI 0.0002 to 0.0068), IL-6 (β = 0.003, 95 % LBCI 0.001 to 0.006), and composite inflammation (β = 0.009, 95 % LBCI 0.004 to 0.018) significantly mediated the association between ACEs and adult depression. The mediation effects no longer survived after adjusting for BMI; however, a serial mediation model revealed that BMI and IL-6 sequentially mediated the association between ACEs and depression (β = 0.002, 95 % LBCI 0.0005 to 0.0046), accounting for 14.59 % and 9.94 % of the variance of IL-6 and depressive symptoms, respectively. Due to the cross-sectional nature of assessment of inflammation and depression findings should be approached with caution; however, results suggest that complex interactions of psychoneuroimmunological and metabolic factors underlie the association between ACEs and adulthood depression.

Childhood trauma exposure, age and self-compassion as predictors of later-life symptoms of depression and anxiety in American Indian adults

BACKGROUND

Although previous research has established a relationship between childhood trauma and later-life anxiety and depression symptoms in American Indian samples, less is known about protective factors that may reduce the strength of this relationship.

OBJECTIVE

The purpose of the present study was to investigate in a sample of American Indian adults, whether age moderates the relationship between self-compassion and poor mental health associated with childhood trauma.

PARTICIPANTS AND SETTING

Seven hundred and twenty-nine self-identifying American Indian adults (age 18-95) residing in the United States completed an online survey.

METHOD

All participants were self-identifying American Indian adults recruited via Qualtrics, which utilized targeted recruiting through managed research panels. Participants self-reported age, gender, income, and completed measures of self-compassion, childhood trauma, and symptoms of anxiety and depression.

RESULTS

Lower self-compassion predicted higher levels of both anxiety symptoms (β = -2.69, R2change = 0.24, t(718) = -15.92, p < .001) and depression symptoms (β = -2.23, R2change = 0.26, t(718) = -16.30, p < .001). In line with our hypothesis, there was a significant three-way interaction between age, childhood trauma exposure and self-compassion in predicting later-life symptoms of anxiety (β = -0.68, t(712) = -3.57, p < .001, R2change = 0.01) and depression (β = -0.54, t(712) = -3.32, p = .001, R2change = 0.01).

CONCLUSIONS

The findings indicate that for older American Indian adults, self-compassion may be a particularly promising protective factor for symptoms of depression for those who have experienced high levels of childhood trauma, and for symptoms of anxiety regardless of childhood trauma exposure.

Adverse childhood experiences and dental anxiety among Chinese adults in Hong Kong: a cross-sectional study

Introduction

This study aimed to investigate the relationship between adverse childhood experiences (ACEs) and dental anxiety among Chinese adults in Hong Kong.

Methods

A cross-sectional survey was conducted at a university in Hong Kong. The recruiting period and data collection started in January 2023 and ended in June 2023. Participants completed an online questionnaire that assessed ACEs (using the Adverse Childhood Experiences International Questionnaire - ACE-IQ) and dental anxiety (using the Modified Dental Anxiety Scale - MDAS and Dental Fear Survey - DFS). The study examined the impacts of both cumulative (i.e., total number) and independent ACE components on dental anxiety. To explore the relationships between cumulative ACEs, individual ACE components and dental anxiety (MDAS and DFS score), Pearson correlations, linear regression and logistic regression were conducted.

Results

Significant associations were observed between ACEs and dental anxiety among 171 subjects. Cumulative ACEs were positively correlated with MDAS scores (r = 0.169, p = 0.027) and DFS scores (r = 0.253, p < 0.001). The odds of an individual having high dental anxiety increased by 26-43% for every additional increase in the number of ACEs. Individual types of ACEs, such as emotional and physical neglect, sexual abuse, and household substance abuse, significantly influenced the likelihood of having high dental anxiety.

Discussion

The results showed a positive association between ACEs and dental anxiety, highlighting the impact of ACEs on dental anxiety. Dental practitioners should consider inquiring about a patient's ACE history to develop personalized treatment plans.

A Strategy To Support Perinatal Mental Health By Collaborating With Tribal Communities In Montana

Among Indigenous women and birthing people, reported rates of perinatal mental health complications are consistently higher than in the general US population. However, perinatal mental health programs and interventions tend to focus on the general population and do not account for the unique experiences and worldviews of Indigenous Peoples. We highlight a collaborative strategy employed by a Montana nonprofit to engage Tribal communities in completing a statewide online resource guide designed to help pregnant and parenting families find resources, including mental health and substance use treatment options, within and beyond their local communities. Based on this strategy, cultural resources relevant to Tribal communities were added to the resource guide. Agencies committed to addressing perinatal mental health disparities among Indigenous populations should consider similar strategies to share power with Tribal communities and collaboratively create culturally congruent programs and interventions.

Influencing Factors of Healthy Aging Risk Assessed Using Biomarkers: A Life Course Perspective

Assessing individual risks of healthy aging using biomarkers and identifying associated factors have become important areas of research. In this study, we conducted a literature review of relevant publications between 2018 and 2023 in both Chinese and English databases. Previous studies have predominantly used single biomarkers, such as C-reactive protein, or focused on specific life course stages and factors such as socioeconomic status, mental health, educational levels, and unhealthy lifestyles. By summarizing the progress in this field, our study provides valuable insights and future directions for promoting healthy aging from a life course perspective.

Depressive symptoms mediate associations of adverse childhood experiences and chronic lung diseases: A mediation effect analysis

BACKGROUND

Adverse childhood experiences (ACEs) have been found to be related to the risk of chronic lung diseases (CLDs). However, the role of depressive symptoms (DS) in this link has not been fully examined. The present study aimed to explore the mediating effect of DS on the relationship between ACEs and CLDs.

METHODS

Data for this retrospective cohort study were obtained from participants enrolled in the China Health and Retirement Longitudinal Study (CHARLS). To assess DS, the 10-item Center for Epidemiological Research Depression Scale was utilized. Logistic regression was employed to explore the associations between ACEs and DS, ACEs and CLDs, as well as depressive symptoms- chronic lung diseases (DS-CLDs). Mediation analysis was conducted to assess the mediating role of DS in the relationship between ACEs and CLDs.

RESULTS

A total of 12,277 participants, comprising 5942 males and 6335 females, were included in this study. Logistic regression analysis identified associations between ACEs and the risk of DS, CLDs, and DS-CLDs. Mediating effect analysis demonstrated that DS had partial mediating effects on the association between CLDs and 7 ACEs, including feel alone, peer bullied, self-reported poor health status, health limitations, death of siblings, physical abuse, and parental mental health. Additionally, DS fully mediated the relationship between CLDs and hunger.

CONCLUSIONS

Our study establishes a significant association between ACEs and CLDs, as well as with DS and DS-CLDs in the elderly population. Furthermore, DS acts as a mediating factor in the ACEs and CLDs relationship.

Profiles of historical loss and childhood trauma as predictors of mental and cardiometabolic health in American Indian adults

Cardiometabolic disease and mental health conditions are two major contributors to persistent inequities in health and life expectancy for American Indian adults. The atrocities associated with European colonization are linked to intergenerational psychological and emotional wounding (i.e., historical trauma) and high incidence of childhood trauma. Prior work has examined the independent relationships of childhood trauma and thoughts about historical loss with cardiometabolic and mental health in American Indians. In the current work, we used a data-driven approach to identify profiles of childhood trauma and frequency of thoughts about historical loss, and then examined how these profiles related to cardiometabolic and mental health in a sample of American Indian adults from across the United States (N = 727). We found that a profile characterized by high levels of childhood trauma and high frequency of thoughts about historical losses was associated with the greatest risk for mental health conditions. The profile characterized by the highest levels of childhood trauma and by moderate frequency of thoughts about historical losses was associated with the largest risk of cardiometabolic conditions. The findings represent an important first step towards understanding how childhood trauma and thoughts about historical loss may simultaneously inform enduring inequities in American Indian health.

Resilience and health in American Indians and Alaska Natives: A scoping review of the literature

American Indians and Alaska Natives suffer from disproportionately high rates of chronic mental and physical health conditions. These health inequities are linked to colonization and its downstream consequences. Most of the American Indian and Alaska Native health inequities research uses a deficit framework, failing to acknowledge the resilience of American Indian and Alaska Native people despite challenging historical and current contexts. This scoping review is based on a conceptual model which acknowledges the context of colonization and its consequences (psychological and health risk factors). However, rather than focusing on health risk, we focus on protective factors across three identified domains (social, psychological, and cultural/spiritual), and summarize documented relationships between these resilience factors and health outcomes. Based on the scoping review of the literature, we note gaps in extant knowledge and recommend future directions. The findings summarized here can be used to inform and shape future interventions which aim to optimize health and well-being in American Indian and Alaska Native peoples.

Anorexia Nervosa in Juvenile Systemic Lupus Erythematosus (SLE): A Causality Dilemma

Juvenile-onset systemic lupus erythematosus (jSLE) is an autoimmune disorder with multifaceted clinical findings in different organ systems. Neuropsychiatric manifestations affect more than half of SLE patients, and there is increasing evidence that anorexia nervosa (AN), a feeding and eating disorder (FED) characterized by significantly reduced energy intake, is among them. Herein, a review of the literature on the potential association between jSLE and AN was performed. Reported clinical cases were identified, and putative pathophysiological mechanisms were sought that could potentially explain the observed relationship between these two pathological entities. Four reports of isolated cases and a case series including seven patients were identified. In this limited patient pool, the diagnosis of AN preceded that of SLE in the majority of cases, whereas in all cases both entities were diagnosed within a time span of two years. Many explanations for the observed relationships have been proposed. AN has been associated with the stress of chronic disease diagnosis; on the other hand, the chronic inflammation associated with AN may contribute to the development/appearance of SLE. Adverse childhood experiences, concentrations of leptin, shared autoantibodies, and genetic traits appear to be important factors in this well-established interplay. In essence, it seems important to increase clinician awareness of the concomitant development of AN and SLE and invite further research on the subject.

Maternal early life stress is associated with pro-inflammatory processes during pregnancy

Early life stress (ELS) is common in the United States and worldwide, and contributes to the development of psychopathology in individuals with these experiences and their offspring. A growing body of research suggests that early life stress may contribute to adverse health partly through modulation of immune (and particularly inflammatory) responses. Therefore, increased maternal prenatal inflammation has been proposed as a mechanistic pathway by which the observed cross-generational effects of parental early life stress on child neuropsychiatric outcomes may be exerted. We examined associations between early life stress and molecular markers of inflammation (specifically pro-inflammatory gene expression and receptor-mediated transcription factor activity) and a commonly studied circulating marker of inflammation (C-Reactive Protein) in a diverse group of women in or near their third trimester of pregnancy, covarying for age, race/ethnicity, BMI, concurrent infection, concurrent perceived stress, and per capita household income. Mothers who experienced higher levels of early life stress had significantly increased pro-inflammatory (NF-κB) and decreased anti-viral (IRF) transcription factor activity. Transcripts that were up or down regulated in mothers with high ELS were preferentially derived from both CD16+ and CD16- monocytes. Early life stress was not associated with elevated CRP. Taken together, these findings provide preliminary evidence for an association between ELS and a pro-inflammatory transcriptional phenotype during pregnancy that may serve as a mechanistic pathway for cross-generational transmission of the effects of early life stress on mental and physical health.

The association between childhood adversity and the conserved transcriptional response to adversity (CTRA) in sexual minority men

Adverse childhood experiences (ACES) increase risk for mental and physical health disorders in adulthood, particularly in individuals from sexual and ethnic minority groups. The effects of ACES on health may be mediated by the immune system. The exact mechanisms by which an environmental exposure, such as childhood adversity, can affect the immune system are still unknown. The aim of this study was to determine whether early adversity predicts significant changes in the expression of a predefined set of immune-related genes, known as the conserved transcriptional response to adversity (CTRA), in a diverse group of sexual minority men (SMM). Participants included HIV positive and negative males from the mSTUDY. Expression data from 53 CTRA genes were obtained at baseline and 12-month follow-up. Childhood adversity was measured with the 10-item ACES questionnaire. Wilcoxon rank sum and chi-squared tests were used to assess differences in sociodemographic variables and HIV status between exposed (cumulative ACES ≥ 3) and unexposed groups (cumulative ACES ≤ 2). Linear mixed models were used to determine associations between ACES (cumulative score, dichotomous measure and subscales) and CTRA gene expression. There were no differences in age and employment status between the exposed and unexposed groups. A larger number of exposed participants were HIV positive than in the unexposed group (p = 0.03). There were no significant associations between any of the ACES variables and CTRA gene expression. A range of factors may have contributed to this unexpected finding. Further studies are needed to assess the biological effects of ACES in adulthood.

Canada's Colonial Genocide of Indigenous Peoples: A Review of the Psychosocial and Neurobiological Processes Linking Trauma and Intergenerational Outcomes

The policies and actions that were enacted to colonize Indigenous Peoples in Canada have been described as constituting cultural genocide. When one considers the long-term consequences from the perspective of the social and environmental determinants of health framework, the impacts of such policies on the physical and mental health of Indigenous Peoples go well beyond cultural loss. This paper addresses the impacts of key historical and current Canadian federal policies in relation to the health and well-being of Indigenous Peoples. Far from constituting a mere lesson in history, the connections between colonialist policies and actions on present-day outcomes are evaluated in terms of transgenerational and intergenerational transmission processes, including psychosocial, developmental, environmental, and neurobiological mechanisms and trauma responses. In addition, while colonialist policies have created adverse living conditions for Indigenous Peoples, resilience and the perseverance of many aspects of culture may be maintained through intergenerational processes.

The immunomodulatory effects of social isolation in mice are linked to temperature control

Living in isolation is considered an emerging societal problem that negatively affects the physical wellbeing of its sufferers in ways that we are just starting to appreciate. This study investigates the immunomodulatory effects of social isolation in mice, utilising a two-week program of sole cage occupancy followed by the testing of immune-inflammatory resilience to bacterial sepsis. Our results revealed that mice housed in social isolation showed an increased ability to clear bacterial infection compared to control socially housed animals. These effects were associated with specific changes in whole blood gene expression profile and an increased production of classical pro-inflammatory cytokines. Interestingly, equipping socially isolated mice with artificial nests as a substitute for their natural huddling behaviour reversed the increased resistance to bacterial sepsis. Together these results suggest that the control of body temperature through social housing and huddling behaviour are important factors in the regulation of the host immune response to infection in mice and might provide another example of the many ways by which living conditions influence immunity.

Using Microbiome-Based Approaches to Deprogram Chronic Disorders and Extend the Healthspan following Adverse Childhood Experiences

Adverse childhood experiences (ACEs), which can include child trafficking, are known to program children for disrupted biological cycles, premature aging, microbiome dysbiosis, immune-inflammatory misregulation, and chronic disease multimorbidity. To date, the microbiome has not been a major focus of deprogramming efforts despite its emerging role in every aspect of ACE-related dysbiosis and dysfunction. This article examines: (1) the utility of incorporating microorganism-based, anti-aging approaches to combat ACE-programmed chronic diseases (also known as noncommunicable diseases and conditions, NCDs) and (2) microbiome regulation of core systems biology cycles that affect NCD comorbid risk. In this review, microbiota influence over three key cyclic rhythms (circadian cycles, the sleep cycle, and the lifespan/longevity cycle) as well as tissue inflammation and oxidative stress are discussed as an opportunity to deprogram ACE-driven chronic disorders. Microbiota, particularly those in the gut, have been shown to affect host–microbe interactions regulating the circadian clock, sleep quality, as well as immune function/senescence, and regulation of tissue inflammation. The microimmunosome is one of several systems biology targets of gut microbiota regulation. Furthermore, correcting misregulated inflammation and increased oxidative stress is key to protecting telomere length and lifespan/longevity and extending what has become known as the healthspan. This review article concludes that to reverse the tragedy of ACE-programmed NCDs and premature aging, managing the human holobiont microbiome should become a routine part of healthcare and preventative medicine across the life course.

Psychological Stress During Childhood and Adolescence and Its Association With Inflammation Across the Lifespan: A Critical Review and Meta-Analysis

Psychological stress during childhood and adolescence increases risk of health problems across the lifecourse, and inflammation is implicated as an underlying mechanism. To evaluate the viability of this hypothesis, we used meta-analysis to quantify the association between childhood/adolescent stress and inflammation over the lifecourse. Furthermore, we addressed three unresolved conceptual questions: (a) Does the strength of this association change over the lifecourse? (b) Are different types of childhood/adolescent stressors differentially associated with inflammation? (c) And which components of the inflammatory response are involved? A systematic search identified 187 articles reporting 922 associations. Meta-analyses were conducted using a three-level multilevel approach and controlled for study quality, conversion confidence, and whether effect sizes were unadjusted or adjusted (n = 662, 72%). Results indicated a small but reliable overall adjusted association ( r ^ = .04 ) . The magnitude of the association strengthened across the lifecourse-effect sizes were smallest in studies that measured inflammation in childhoodr ^ = .02 and became progressively larger in studies of adolescencer ^ = .04 and adulthoodr ^ = .05 , suggesting the impact of early stress strengthens with time. By contrast, effect sizes did not vary by adversity type (socioeconomic disadvantage, maltreatment, other interpersonal stressors, and cumulative exposure across stressors), or component of inflammation (circulating biomarkers of low-grade inflammation vs. cytokine responses to microbial stimuli). Implications and future directions are discussed.

Adverse Childhood Experiences and Trajectories of ADL Disability among Middle-Aged and Older Adults in China: Findings from the CHARLS Cohort Study

OBJECTIVES

There is little evidence on the association between adverse childhood experiences (ACEs) and disability trajectories among middle-aged and older adults. This study aimed to investigate the association between ACEs and activities of daily living (ADL) trajectories over eight years of follow-up and the mediation role of different chronic diseases on this relationship.

DESIGN

Prospective cohort study, eight-year follow-up.

SETTING

China Health and Retirement Longitudinal Study(CHARLS).

PARTICIPANTS

A total of 10651 participants age 45 and over from CHARLS 2011 to 2018 were included in this study.

MEASUREMENTS

Five ACEs exposure groups were formed based on the cumulative ACE scores. A 6-item ADL score was used, including bathing, dressing, eating, getting in/out of bed, using the toilet, and controlling urination, to measure the ADL disability, and the group-based trajectory model (GBTM) was used to identify the ADL disability trajectories. Multinomial logistic regression was performed to investigate the association between ACEs and ADL disability trajectory memberships, and KHB-method was used to estimate the contribution of different chronic diseases on this relationship.

RESULTS

Of the 10651 participants, 9.64% showed a mild-increasing trajectory in terms of change in ADL score during follow-up, followed by the low-mild trajectory (32.00%) and low-low trajectory (58.36%). Compared with those without ACEs exposure, participants who had ≥4 ACEs were associated with an increased risk of being on low-mild trajectory (OR 1.32, 95%CI:1.11-1.57) and mild-increasing trajectory (OR 1.41, 95%CI: 1.06-1.89), respectively. Besides, mediation analysis revealed chronic diseases had a mediation effect in this association, with the largest effect from arthritis or rheumatism (over 60%), followed by digestive system disease (around 14%), respiratory disease (around 12%), and cardio-metabolic disease (around 5%).

CONCLUSION

This study suggested that exposure to ACEs was associated with a higher risk of being worse ADL disability trajectories. Moreover, chronic disease accounts for a meaningful proportion of this association. Further studies are needed to clarify how chronic diseases mediate the association between ACEs and ADL disability trajectories.

Adverse childhood experiences and adult diet quality

Childhood trauma is strongly associated with poor health outcomes. Although many studies have found associations between adverse childhood experiences (ACEs), a well-established indicator of childhood trauma and diet-related health outcomes, few have explored the relationship between ACEs and diet quality, despite growing literature in epidemiology and neurobiology suggesting that childhood trauma has an important but poorly understood relationship with diet. Thus, we performed a cross-sectional study of the association of ACEs and adult diet quality in the Southern Community Cohort Study, a largely low-income and racially diverse population in the southeastern United States. We used ordinal logistic regression to estimate the association of ACEs with the Healthy Eating Index-2010 (HEI-10) score among 30 854 adults aged 40-79 enrolled from 2002 to 2009. Having experienced any ACE was associated with higher odds of worse HEI-10 among all (odds ratio (OR) 1⋅22; 95 % confidence interval (CI) 1⋅17, 1⋅27), and for all race-sex groups, and remained significant after adjustment for adult income. The increasing number of ACEs was also associated with increasing odds of a worse HEI-10 (OR for 4+ ACEs: 1⋅34; 95 % CI 1⋅27, 1⋅42). The association with worse HEI-10 score was especially strong for ACEs in the household dysfunction category, including having a family member in prison (OR 1⋅34; 95 % CI 1⋅25, 1⋅42) and parents divorced (OR 1⋅25; 95 % CI 1⋅20, 1⋅31). In summary, ACEs are associated with poor adult diet quality, independent of race, sex and adult income. Research is needed to explore whether trauma intervention strategies can impact adult diet quality.

Inflammation and early life stress: An updated review of childhood trauma and inflammatory markers in adulthood

Inflammation, as a neurobiological consequence of childhood trauma, has frequently been reported across research, however, recent investigations suggest this relationship may be dependent on specificities such as type of trauma, type of inflammatory marker, and additional mediatory variables - such as body mass index (BMI), age, and sex. As an updated version of a previous review by Baumeister et al., the current review comprised a search of PubMed, which identified 37 articles that collectively assessed 4 inflammatory markers (CRP, IL-6, TNFα and IL-1β). A review of the studies revealed predominantly non-significant associations between childhood trauma and elevated levels of all inflammatory markers in adulthood. However, in line with previous research, discrepancies in significance arose when considering type of trauma, type of inflammatory marker, and additional variables. Compared to neglect, abuse showed greater significant associations with elevated inflammatory markers in adulthood, though this was dependent on the individual subtypes (emotional, physical or sexual). Mediation analyses reported BMI as a significant mediator, though, when controlled for, no significant differences were found. Sex differences were reported but investigations were sparse. Future research should investigate the mediatory role of sex differences in the inflammatory effects of childhood trauma. Many studies in the review were restricted by use of the same trauma measure - the Childhood Trauma Questionnaire. To assess greater variety of trauma types, future studies should utilize other standardized measures to explore these avenues.

Does being psychologically resilient assist in optimising physical outcomes from a spinal cord injury? Findings from a systematic scoping review

PURPOSE

To systematically search for current research on the role of resilience in the physical rehabilitation of SCI and describe the research to date.

MATERIALS AND METHODS

The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) approach was used. Five databases were searched for papers published up to March 2020. The sample included adults who have sustained an SCI; outcomes included a physical rehabilitation outcome and a measure of psychological or personal resilience/resilience training.

RESULTS

The initial search found 2074 studies. 12 studies were included. Six suggest positive effects of resilience on physical functioning/recovery, six report resilience as not affecting physical functioning/recovery.

CONCLUSIONS

Resilience may positively affect physical outcomes; however, the relationship is under-researched and contrasting findings may be due to measurements and methods employed by research. Future research may distinguish between two sources of resilience following an SCI: prior resilient experiences, and resilience as a product of the injury. Individuals' past events that triggered resilient behaviour may be able to promote a resilient response to an SCI. Focussing on emotional coping may result in poorer outcomes than building a sense of control. Resilience training may affect psychosocial rehabilitation; it is difficult to establish if it would affect physical outcomes. A negative approach to an injury can have negative effects on functioning; when identifying patients for psychoeducational training, those with the presence of negative appraisals of their injury are most in need.IMPLICATIONS FOR REHABILITATIONResilience may positively affect physical outcomes; however, the relationship is under-researched.Individuals' past events that triggered resilient behaviour may be able to promote a resilient response to an SCI.Focussing on emotional coping may result in poorer outcomes than building a sense of control.When identifying patients for psychoeducational training, it may be those with the presence of negative appraisals of their injury that are most in need.

Historical Loss: Implications for Health of American Indians in the Blackfeet Community

BACKGROUND

Historical loss in American Indians (AIs) is believed to contribute to high incidence of mental health disorders, yet less is known about the associations between historical loss and physical health.

PURPOSE

To investigate whether frequency of thought about historical loss predicts risk factors for chronic physical health conditions in an AI community.

METHODS

Using Community Based Participatory research (CBPR) and Ecological Momentary Assessment (EMA), we measured frequency of thoughts about historical loss in 100 AI adults residing on the Blackfeet reservation. Participants completed a 1-week monitoring period, during which ambulatory blood pressure and daily levels of psychological stress were measured. At the end of the week, we collected a dried blood spot sample for measurement of C-reactive protein (CRP).

RESULTS

In hierarchical linear regression models controlling for demographics and relevant covariates, greater frequency of thoughts about historical loss predicted higher average daily psychological stress (B = .55, t = 6.47, p < .001, ΔR2 = .30) and higher levels of CRP (B = .33, t = 3.93, p < .001, ΔR2 = .10). Using linear mixed modeling with relevant covariates, we found that greater thoughts about historical loss were associated with higher systolic ambulatory blood pressure (B = .32, 95% CI = .22-.42, t = 6.48, p < .001, ΔR2 = .25; Fig. 1c) and greater diastolic ambulatory blood pressure (B = .19, 95% CI = .11-.27, t = 4.73, p < .001, ΔR2 = .19).

CONCLUSIONS

The data suggest that frequency of thought about historical loss may contribute to increased subclinical risk for cardiovascular disease in the Blackfeet community.

Racial/Ethnic Differences in Food Allergy

Immunoglobulin E-mediated food allergy is an increasingly prevalent public health concern globally. In North America, particularly in the United States, racial and ethnic differences in food allergy prevalence and rates of sensitization have become apparent. Black and Hispanic children in the United States have been estimated to have the highest rates of food allergy. Beyond rates of prevalence, food allergy outcomes, such as health care utilization, psychosocial outcomes, and economic burden, also vary considerably by race and ethnicity. It is important to consider socioeconomic status in conjunction with race and ethnicity in studying differences in food allergy outcomes.

Challenges in researching the immune pathways between early life adversity and psychopathology

Exposure to childhood adversity is a critical risk factor for the development of psychopathology. A growing field of research examines how exposure to childhood adversity is translated into biological risk for psychopathology through alterations in immune system functioning, most notably heightened levels of inflammation biomarkers. Though our knowledge about how childhood adversity can instantiate biological risk for psychopathology is growing, there remain many challenges and gaps in the field to understand how inflammation from childhood adversity contributes to psychopathology. This paper reviews research on the inflammatory outcomes arising from childhood adversity and presents four major challenges that future research must address: (a) the measurement of childhood adversity, (b) the measurement of inflammation, (c) the identification of mediators between childhood adversity and inflammation, and (d) the identification of moderators of inflammatory outcomes following childhood adversity. We discuss synergies and inconsistencies in the literature to summarize the current understanding of the association between childhood adversity, a proinflammatory phenotype, and the biological risk for psychopathology. We discuss the clinical implications of the inflammatory links between childhood adversity and psychopathology, including possibilities for intervention. Finally, this review conclude by delineates future directions for research, including issues of how best to detect, prevent, and understand these “hidden wounds” of childhood adversity.

Intersections of Adverse Childhood Experiences, Race and Ethnicity and Asthma Outcomes: Findings from the Behavioral Risk Factor Surveillance System

Racial and ethnic minority subpopulations experience a disproportionate burden of asthma and adverse childhood experiences (ACEs). These disparities result from systematic differences in risk exposure, opportunity access, and return on resources, but we know little about how accumulated differentials in ACEs may be associated with adult asthma by racial/ethnic groups. We used Behavioral Risk Factor Surveillance System data (N = 114,015) from 2009 through 2012 and logistic regression to examine the relationship between ACEs and adult asthma using an intersectional lens, investigating potential differences for women and men aged 18 and older across seven racial/ethnic groups. ACEs were significantly related to asthma, adjusting for race/ethnicity and other covariates. Compared to the reference group (Asians), asthma risk was significantly greater for Black/African American, American Indian and Alaska Native (AIAN), White, and multiracial respondents. In sex-stratified interactional models, ACEs were significantly related to asthma among women. The relationship between ACEs and asthma was significantly weaker for Black/African American and AIAN women compared to the reference group (Asian women). The findings merit attention for the prevention and early detection of ACEs to mitigate long-term health disparities, supporting standardized screening and referrals in clinical settings, evidence-based prevention in communities, and the exploration of strategies to buffer the influence of adversities in health.
