Health and financial burden of adverse childhood experiences in England and Wales: a combined primary data study of five surveys

Effects of childhood adversities on alexithymia features vary between sexes. Results of a prospective population study

Introduction: Adverse childhood experiences (ACEs) associate with various mental disorders, including personality features. Our understanding of how ACEs influence alexithymia features in the general population is limited. In a prospective population setting, we studied whether ACEs associate with alexithymia, and the role of sex and emotional symptoms in this association.Methods: In a Finnish population-based prospective study, 3,142 individuals aged between 30 and 64 years completed eleven ACE questions and the Toronto Alexithymia Scale in 2000 and 2011, and the Hopkins Symptoms Checklist in 2011. The effect of ACEs on alexithymia and its subdomains - difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and externally oriented thinking (EOT) in 2000 and 2011 - was analysed using repeated measures ANOVA.Results: The number of ACEs and their main component, childhood social disadvantage, associated positively with total alexithymia scores and its subdomains DIF and DDF, and negatively with EOT. After controlling for the effect of depression and anxiety, the strength of these associations was reduced, but the effect of social disadvantage on DIF and EOT remained significant in females. Childhood family conflicts associated positively with DIF in males and negatively with EOT in females. Additionally, maternal mental problems associated positively with DIF and DDF in females.Discussion: In the general population, ACEs, particularly social disadvantage, are associated with adult alexithymia features. Alexithymia features, detectable from youth, may predispose individuals to emotional disturbances caused by childhood adversities. The effect of family conflicts and maternal mental problems on alexithymia features varies between sexes.

Adverse childhood experiences exacerbate peripheral symptoms of autism spectrum disorder in adults

AIM

Adverse childhood experiences are potentially traumatic events with long-lasting effects on the health and well-being of patients with autism spectrum disorder (ASD). It is important to clarify which types of long-lasting autism-related symptoms are influenced by childhood experiences to design future intervention studies. However, few studies have examined the association between childhood experiences and autistic symptoms in large samples of adults with ASD and individuals with typical development (TD). In this study, we evaluate the effects of adverse childhood experiences on multiple ASD phenotypes among both individuals with ASD and those with TD.

METHOD

We combined questionnaire evaluations; Childhood Abuse and Trauma Scale, the Japanese version of the Autism-Spectrum Quotient, Conners' Adult ADHD Rating Scale, the Japanese version of the Impact of Event Scale-Revised, and the Japanese version of the Adolescent/Adult Sensory Profile.

RESULTS

Individuals with ASD and those with TD (n = 205 and 104, respectively) were included. There were significant correlations between the extent of adverse childhood experiences and severity of attention-deficit/hyperactivity disorder symptoms, posttraumatic stress disorder symptoms, and hypersensitivity in both participants with ASD and those with TD. By contrast, ASD core symptoms showed no significant correlation with adverse childhood experiences in either group. These results remained consistent after adjusting for age, sex, and the estimated intelligence quotient.

CONCLUSION

These findings suggest the need for a detailed disentanglement of ASD-related core and peripheral symptoms of adverse childhood experiences, which may help to appropriately set outcomes for future early interventions for the childhood experiences of individuals with ASD.

Noradrenergic alterations associated with early life stress

Significant stress in childhood or adolescence is linked to both structural and functional changes in the brain in human and analogous animal models. In addition, neuromodulators, such as noradrenaline (NA), show life-long alterations in response to these early life stressors, which may impact upon the sensitivity and time course of key adrenergic activities, such as rapid autonomic stress responses (the 'fight or flight response'). The locus-coeruleus noradrenergic (LC-NA) network, a key stress-responsive network in the brain, displays numerous changes in response to significant early- life stress. Here, we review the relationship between NA and the neurobiological changes associated with early life stress and set out future lines of research that can illuminate how brain circuits and circulating neurotransmitters adapt in response to childhood stressors.

Adverse Childhood Experiences and Risk of Abnormal Body Mass Index: A Global Systematic Review and Meta-Analysis

(1) Objectives: The impact of abnormal body mass index (BMI) on health is extensive, and various risk factors contribute to its effects. This study aimed to examine the association between adverse childhood experiences (ACEs) and BMI categories, including underweight, overweight, obesity, severe obesity, and morbid obesity; (2) Methods: Three databases were searched: Web of Science, PubMed, and Scopus. Manual searches were conducted using Google Scholar and ResearchGate. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between ACEs and BMI. A random-effects model was used to combine the ORs and CIs across studies; (3) Results: This meta-analysis included 71 studies. The pooled ORs for the relationship between ACEs and obesity was 1.42 (95% CI: 1.24-1.63, Z = 4.96, p < 0.001), indicating a significant association. ACEs showed a positive association with overweight (OR = 1.16, 95% CI: 1.06-1.27, Z = 3.24, p = 0.001). Specifically, ACEs ≥ 4 were strongly associated with obesity (OR = 2.06, 95% CI: 1.27-3.36, Z = 2.90, p = 0.004). Sexual abuse was also found to be significantly associated with obesity (OR = 1.46, 95% CI: 1.29-1.65, Z = 5.98, p < 0.001); (4) Conclusion: This study finds that individuals who have experienced ACEs are more likely to have a higher BMI in adulthood. Therefore, ACEs should be considered a factor associated with abnormal BMI.

Exploring clinicians' knowledge and attitudes toward the care needs of complex adult users of an Emergency Department: A descriptive mixed methods study

BACKGROUND

Adults who frequently present (FPAs) to emergency departments (EDs) often have a history of adverse childhood experiences (ACEs) and related adult health sequelae. Implications for ED care of this group remains poorly understood. This study explored clinicians' knowledge and attitudes toward the care needs of FPAs who have an ACEs history, providing preliminary evidence to inform further research and interventions.

METHODS

A purposive sample of ED clinicians completed an investigator developed mixed-methods survey. Descriptive statistics and content analysis were applied.

RESULTS

Forty-three ED clinicians completed the survey. Most perceived that ACEs were common among FPAs and influenced their ED presentations. Clinicians were more aware of the psychosocial impacts of ACEs than the risks to physical health. While most clinicians agreed that FPAs should be asked about ACEs for management planning, most never asked, describing multiple barriers to doing so. Consumer's healthcare needs were often described as unmet by clinicians who desired additional support to provide care for this group.

CONCLUSIONS

This study highlights clinicians' perceptions of gaps in healthcare for this patient group and introduces requirements for appropriate knowledge and resources to partner with consumers to provide patient-centred and trauma-informed health care responses.

Service evaluation of an independent domestic violence advocate post in a children's hospital

Domestic violence and abuse (DVA) has detrimental effects on the health and well-being of children and young people exposed to it, whether they witness or experience it. The introduction of independent domestic violence advocates in UK hospitals has enhanced the safety of victims of DVA. In 2020-2021 an independent domestic violence advocate post was piloted at a children's hospital for one year, the advocate's role being to train hospital staff and support women who had experienced DVA. A service evaluation showed that the training and support provided by the independent domestic violence advocate had benefits for women, children and staff. It also confirmed that the commissioning of services for children exposed to DVA is often underfunded and overshadowed by the provision of support to adults.

Examining relationships between adverse childhood experiences and coping during the cost-of-living crisis using a national cross-sectional survey in Wales, UK

OBJECTIVES

Adverse childhood experiences (ACEs) can affect individuals' resilience to stressors and their vulnerability to mental, physical and social harms. This study explored associations between ACEs, financial coping during the cost-of-living crisis and perceived impacts on health and well-being.

DESIGN

National cross-sectional face-to-face survey. Recruitment used a random quota sample of households stratified by health region and deprivation quintile.

SETTING

Households in Wales, UK.

PARTICIPANTS

1880 Welsh residents aged ≥18 years.

MEASURES

Outcome variables were perceived inability to cope financially during the cost-of-living crisis; rising costs of living causing substantial distress and anxiety; and self-reported negative impact of rising costs of living on mental health, physical health, family relationships, local levels of antisocial behaviour and violence, and community support. Nine ACEs were measured retrospectively. Socioeconomic and demographic variables included low household income, economic inactivity, residential deprivation and activity limitation.

RESULTS

The prevalence of all outcomes increased strongly with ACE count. Perceived inability to cope financially during the cost-of-living crisis increased from 14.0% with 0 ACEs to 51.5% with 4+ ACEs. Relationships with ACEs remained after controlling for socioeconomic and demographic factors. Those with 4+ ACEs (vs 0 ACEs) were over three times more likely to perceive they would be unable to cope financially and, correspondingly, almost three times more likely to report substantial distress and anxiety and over three times more likely to report negative impacts on mental health, physical health and family relationships.

CONCLUSIONS

Socioeconomically deprived populations are recognised to be disproportionately impacted by rising costs of living. Our study identifies a history of ACEs as an additional vulnerability that can affect all socioeconomic groups. Definitions of vulnerability during crises and communications with services on who is most likely to be impacted should consider childhood adversity and history of trauma.

Tobacco use behavior among adults exposed to cumulative adverse childhood experiences: A systematic review and meta analysis

BACKGROUND

Tobacco use remains one of the most used substances among adults globally and substantially impacts individuals and society. Adverse childhood experiences (ACEs) contribute to tobacco use. However, the association between cumulative ACEs and tobacco use behaviors (TUB) has not been established in the literature. In this review, we aimed to estimate the prevalence of ACEs among adult tobacco users and evaluated the relationship between cumulative ACEs and TUB.

METHODS

We identified original articles published before October 2022 by searching PubMed, CINAHL, and Psych INFO databases. Inclusion criteria were: English language, adults and used instruments assessing for cumulative ACEs defined as four or more ACEs.

RESULTS

Forty-two studies, totaling 674,087 participants; predominantly cohort and cross-sectional in study design (n = 33). Exposure to 4 ≥ ACEs was significantly associated with increasing the odds of current tobacco use (n = 35), ever or former tobacco use (n = 13), tobacco use initiation, (n = 3) nicotine dependence (n = 1), and ever using electronic cigarettes (n = 1). In the meta-analysis, as compared to those without ACEs, those with 4 ≥ ACEs were twice as likely to have ever used tobacco (OR = 2.16, 95 %CI:1.73-2.70) and approximately four times more likely to have used tobacco currently (OR = 3.73, 95 %CI:2.69-5.18).

CONCLUSION

The cumulative ACEs exposure can increase the risk for TUB. However, the evidence is limited primarily to cigarette use. Ongoing research into the effects of cumulative ACEs on TUB is needed to integrate trauma-informed intervention in treating tobacco use and guide public health initiatives aimed to reduce the prevalence of ACEs and TUB among adults.

Making Connections: Neurodevelopmental Changes in Brain Connectivity After Adverse Experiences in Early Adolescence

Adverse childhood experiences have been linked to detrimental mental health outcomes in adulthood. This study investigates a potential neurodevelopmental pathway between adversity and mental health outcomes: brain connectivity. We used data from the prospective, longitudinal Adolescent Brain Cognitive Development (ABCD) study (N ≍ 12.000, participants aged 9-13 years, male and female) and assessed structural brain connectivity using fractional anisotropy (FA) of white matter tracts. The adverse experiences modeled included family conflict and traumatic experiences. K-means clustering and latent basis growth models were used to determine subgroups based on total levels and trajectories of brain connectivity. Multinomial regression was used to determine associations between cluster membership and adverse experiences. The results showed that higher family conflict was associated with higher FA levels across brain tracts (e.g., t (3) = -3.81, β = -0.09, p bonf = 0.003) and within the corpus callosum (CC), fornix, and anterior thalamic radiations (ATR). A decreasing FA trajectory across two brain imaging timepoints was linked to lower socioeconomic status and neighborhood safety. Socioeconomic status was related to FA across brain tracts (e.g., t (3) = 3.44, β = 0.10, p bonf = 0.01), the CC and the ATR. Neighborhood safety was associated with FA in the Fornix and ATR (e.g., t (1) = 3.48, β = 0.09, p bonf = 0.01). There is a complex and multifaceted relationship between adverse experiences and brain development, where adverse experiences during early adolescence are related to brain connectivity. These findings underscore the importance of studying adverse experiences beyond early childhood to understand lifespan developmental outcomes.

Mediating pathways that link adverse childhood experiences with cardiovascular disease

OBJECTIVES

There is uncertainty about which factors mediate the association between adverse childhood experiences (ACEs) and cardiovascular disease (CVD). This could inform secondary prevention targets.

STUDY DESIGN

Mediation analysis of a prospective cohort study.

METHODS

English Longitudinal Study of Ageing (ELSA) wave 3 data (2006/7) were used to measure retrospective exposure to 12 individual ACEs and waves 2 to 4 (2004/5 to 2008/9) data to measure current exposure to potential mediators [smoking, physical activity, alcohol consumption, body mass index, depression, and C-reactive protein (CRP)]. Waves 4 to 9 ELSA data (2008/9 to 2018/19) were used to measure incident CVD. Cumulative ACE exposure was categorised into experiencing 0, 1 to 3, or ≥4 individual ACEs. Associations were tested between ACE categories, potential mediators, and incident CVD, to inform which variables were analysed in causal mediation models.

RESULTS

The analytical cohort consisted of 4547 participants (56% women), with a mean age of 64 years (standard deviation = 9 years). At least one ACE had been experienced by 45% of the cohort, and 24% developed incident CVD over a median follow-up period of 9.7 years (interquartile range: 5.3-11.4 years). After adjusting for potential confounders, experiencing ≥4 ACEs compared with none was associated with incident CVD [odds ratio (OR): 1.55; 95% confidence interval (CI): 1.10, 2.17], and the association of one to three ACEs compared with none was non-significant (OR: 1.08; 95% CI: 0.93, 1.24). There were two statistically significant mediators of the association between ≥4 ACEs and incident CVD: CRP and depression, which accounted for 10.7% and 10.8% of the association, respectively.

CONCLUSIONS

Inflammation and depression partially mediated the association between ACEs and CVD. Targeting these factors may reduce the future incidence of CVD.

Economic Burden of Health Conditions Associated With Adverse Childhood Experiences Among US Adults

Importance

Adverse childhood experiences (ACEs) are preventable, potentially traumatic events in childhood, such as experiencing abuse or neglect, witnessing violence, or living in a household with substance use disorder, mental health problems, or instability from parental separation or incarceration. Adults who had ACEs have more harmful risk behaviors and worse health outcomes; the economic burden associated with these issues is uncertain.

Objective

To estimate the economic burden of ACE-associated health conditions among US adults.

Design, Setting, and Participants

In this economic evaluation, regression models of cross-sectional survey data from the 2019-2020 Behavioral Risk Factor Surveillance System (BRFSS) and previous studies were used to estimate ACE population-attributable fractions (PAFs) (ie, the fraction of total cases associated with a specific exposure) for selected health outcomes (anxiety, arthritis, asthma, cancer, chronic obstructive pulmonary disease, depression, diabetes, heart disease, kidney disease, stroke, and violence) and risk factors (heavy drinking, illicit drug use, overweight and obesity, and smoking) among the 2019 US adult population. Adverse childhood experience PAFs were used to calculate the proportion of total condition-specific medical spending and lost healthy life-years related to ACEs using Global Burden of Disease Study data. Data analysis was performed from September 10, 2021, to November 29, 2022.

Exposure

Adverse childhood experiences (age <18 years).

Main Outcomes and Measures

Monetary valuation of ACE-associated morbidity and mortality using standard US value of statistical life methods and presented in terms of annual and lifetime per affected person and total population estimates at the national and state levels.

Results

A total of 820 673 adults, representing 255 million individuals, participated in the BRFSS in 2019 and 2020. An estimated 160 million of the total 255 million US adult population (63%) had 1 or more ACE, associated with an annual economic burden of $14.1 trillion ($183 billion in direct medical spending and $13.9 trillion in lost healthy life-years). This was $88 000 per affected adult annually and $2.4 million over their lifetimes. The lifetime economic burden per affected adult was lowest in North Dakota ($1.3 million) and highest in Arkansas ($4.3 million). Twenty-two percent of adults had 4 or more ACEs and comprised 58% of the total economic burden-the estimated per person lifetime economic burden for those adults was $4.0 million.

Conclusions and Relevance

In this cross-sectional analysis of the US adult population, the economic burden of ACE-related health conditions was substantial. The findings suggest that measuring the economic burden of ACEs can support decision-making about investing in strategies to improve population health.

Impact of adverse childhood experiences on life expectancy with depression in the U.K. population: The mitigating role of educational attainment

BACKGROUND

Adverse childhood experiences (ACEs) are associated with depression in later life.

OBJECTIVE

This study aimed to measure the impact of ACEs on life expectancy with depression (DLE) and to assess how educational attainment affected expectations.

PARTICIPANTS AND SETTING

The study used data on 5597 participants from the English Longitudinal Study of Aging (2006-2013).

METHODS

Depression was assessed through the eight-item short version of the Centre for Epidemiologic Studies Depression. We used discrete-multistate life table models to estimate total life expectancy and life expectancy with depression.

RESULTS

Older adults with ACEs had longer DLE and a higher proportion of remaining life with depression compared with those without ACEs. For example, men aged 60 years with ACEs could expect to live 5.2 (95 % confidence interval (CI): 4.2, 6.2) years with depression compared with 2.8 (95 % CI: 2.3, 3.3) years for men without ACEs. Women aged 60 years who reported ACEs could expect to live 9.4 (95 % CI: 7.6, 11.1) years with depression compared with 6.0 (95 % CI: 5.1, 7.0) years for women without ACEs. With a high level of educational attainment, older adults from younger cohorts with ACEs lived fewer depression years and spent a higher proportion of their life being free of depression than adults with ACEs and had a low level of educational attainment.

CONCLUSION

Our results indicated that ACEs may increase years of life with depression among U.K. adults. Meanwhile, high educational attainment could mitigate the mental health burden associated with ACEs.

Prospective longitudinal associations between adverse childhood experiences and adult mental health outcomes: a protocol for a systematic review and meta-analysis

BACKGROUND

Research cites a strong, dose-response relationship between adverse childhood experiences (ACEs) and poor adult mental health outcomes including anxiety, depression, post-traumatic stress disorder (PTSD), self-harm, suicidality, and psychotic-like experiences.

AIM

To systematically investigate the existence and strength of association between ACEs and adult mental health outcomes in prospective longitudinal studies. The review will focus on the outcomes: anxiety, depression, PTSD, self-harm, suicidal ideation, and psychotic-like experiences.

METHODS

Twelve electronic databases will be searched: Embase, PsycINFO, MEDLINE, and Global Health through the OVID interface. ProQuest will be used to search Public Affairs Information Service (PAIS), Dissertations and Theses, Sociology Database (including Sociological Abstracts and Social Services Abstracts), PTSDpubs (formerly The Published International Literature on Traumatic Stress (PILOTS) Database) and Applied Social Sciences Index and Abstracts (ASSIA). CINAHL, World Health Organisation (WHO) Global Index Medicus, and WHO Violence Info will also be searched. Eligible studies will be double screened, assessed, and their data will be extracted. Any disagreement throughout these processes will be settled by a third reviewer. If enough studies meet the criteria and the methodological quality of each study is sufficient, a meta-analysis will be conducted.

ANALYSIS

A narrative synthesis of included studies and the associations between ACEs and adult mental health will be completed. If the number of studies included per mental health outcome is two or more, a multi-level meta-analysis will be completed using odds ratio effect sizes as outcomes.

DISCUSSION

This review will contribute to the existing body of literature supporting the long-term effects of ACEs on adult mental health. This review adds to previous reviews that have either synthesised cross-sectional associations between ACEs and mental health outcomes, synthesised longitudinal studies exploring the effect of ACEs on different physical and mental health outcomes or synthesised longitudinal studies exploring the effect of ACEs on the same mental health outcomes using different methods. This review aims to identify methodological weaknesses and knowledge gaps in current literature that can be addressed in future primary studies.

SYSTEMATIC REVIEW REGISTRATION

This protocol has been registered in PROSPERO (CRD42021297882).

Measuring changes in adult health and well-being during the COVID-19 pandemic and their relationship with adverse childhood experiences and current social assets: a cross-sectional survey

BACKGROUND

Adverse childhood experiences (ACEs) can impact mental and physical health, leaving people with less resilience to health challenges across the life-course. This study examines whether individuals' levels and changes in levels of mental health, physical health and sleep quality reported across the first year of the COVID-19 pandemic are associated with ACEs and moderated by social assets such as having trusted family and friends.

METHODS

A cross-sectional household telephone survey in England (a North West local authority) and Wales (nationally) using landline and mobile numbers stratified by health areas, deprivation quintile and age group and supplemented by an online survey. Data were collected from 4,673 English and Welsh residents aged ≥ 18 years during national COVID-19 restrictions (December 2020 to March 2021). Measures included nine types of ACE; self-reported mental health, physical health and sleep quality at time of survey (in pandemic) and one-year earlier (pre-pandemic); numbers of trusted family members and friends, knowledge of community help; and COVID-19 infection.

RESULTS

ACEs were strongly related to moving into poorer mental health, physical health, and sleep categories during the pandemic, with likelihoods more than doubling in those with ≥ 4 ACEs (vs. 0). ACEs were also associated with increased likelihood of moving out of poorer health and sleep categories although this was for a much smaller proportion of individuals. Individuals with more trusted family members were less likely to move into poorer health categories regardless of ACE counts.

CONCLUSIONS

ACEs are experienced by large proportions of populations and are associated with poorer health even in non-pandemic situations. However, they also appear associated with greater vulnerability to developing poorer health and well-being in pandemic situations. There is a minority of those with ACEs who may have benefited from the changes in lifestyles associated with pandemic restrictions. Connectedness especially with family, appears an important factor in maintaining health during pandemic restrictions.

Comparing relationships between single types of adverse childhood experiences and health-related outcomes: a combined primary data study of eight cross-sectional surveys in England and Wales

OBJECTIVES

Adverse childhood experiences (ACEs) show strong cumulative associations with ill-health across the life course. Harms can arise even in those exposed to a single ACE type but few studies examine such exposure. For individuals experiencing a single ACE type, we examine which ACEs are most strongly related to different health harms.

DESIGN

Secondary analysis of combined data from eight cross-sectional general population ACE surveys.

SETTING

Households in England and Wales.

PARTICIPANTS

20 556 residents aged 18-69 years.

MEASURES

Ten self-reported outcomes were examined: smoking, cannabis use, binge drinking, obesity, sexually transmitted infection, teenage pregnancy, mental well-being, violence perpetration, violence victimisation and incarceration. Adjusted ORs and percentage changes in outcomes were calculated for each type of ACE exposure.

RESULTS

Significance and magnitude of associations between each ACE and outcome varied. Binge drinking was associated with childhood verbal abuse (VA), parental separation (PS) and household alcohol problem (AP), while obesity was linked to sexual abuse (SA) and household mental illness. SA also showed the biggest increase in cannabis use (25.5% vs 10.8%, no ACEs). Household AP was the ACE most strongly associated with violence and incarceration. PS was associated with teenage pregnancy (9.1% vs 3.7%, no ACEs) and 5 other outcomes. VA was associated with 7 of the 10 outcomes examined.

CONCLUSION

Exposure to a single ACE increases risks of poorer outcomes across health-harming behaviours, sexual health, mental well-being and criminal domains. Toxic stress can arise from ACEs such as physical and SA but other more prevalent ACEs (eg, VA, PS) may also contribute substantively to poorer life course health.

Association between early life adversity and allostatic load in girls with precocious puberty

CONTEXT

The mechanisms underlying the elevated long-term health risk in girls with precocious puberty remain unclear, but might result from physiological wear and tear associated with greater exposure to early life adversity.

OBJECTIVE

This study aims to explore early life adversity in girls with precocious puberty and its association with allostatic load.

METHODS

Early life adversity and hair cortisol concentration were measured among 213 girls with precocious puberty (8.21 ± 1.07). Allostatic load score is constructed by using 13 physiological biomarkers representing four systems and hair cortisol concentration. Multivariate linear regression models have estimated the associations between cumulative early life adversity exposure with total and system-specific allostatic load scores. Associations between cumulative early life adversity and the risk of high allostatic load (3 + high-risk biomarkers) were tested using binary logistics regression.

RESULTS

More than two-thirds (67.6%) of girls with central precocious puberty reported two or more early life adversity exposure. Compared to those with no early life adversity exposure, girls who reported early life adversity score ≥ 2 had significantly higher total allostatic load score (β: 1.20-1.64, P < 0.001). Metabolic system was more sensitive to cumulative early life adversity exposure, each form of early life adversity exposure was associated with 0.48-unit increases in metabolic allostatic load score (95%CI: 0.06, 0.90, P = 0.026). Girls reported early life adversity score ≥ 3 were three times more likely to have a high allostatic load compared with those without early life adversity exposure in both unadjusted and adjusted models (OR_adjusted=3.83, 95%CI: 1.17, 12.55, P = 0.001).

CONCLUSION

Multisystem physiological dysregulation is observed in girls with central precocious puberty, which might result from cumulative wear-and-tear associated with early life adversity.

The interactive association of adverse childhood experiences and polygenic susceptibility with depressive symptoms and chronic inflammation in older adults: a prospective cohort study

BACKGROUND

Adverse childhood experiences (ACEs) and genetic liability are important risk factors for depression and inflammation. However, little is known about the gene-environment (G × E) mechanisms underlying their aetiology. For the first time, we tested the independent and interactive associations of ACEs and polygenic scores of major depressive disorder (MDD-PGS) and C-reactive protein (CRP-PGS) with longitudinal trajectories of depression and chronic inflammation in older adults.

METHODS

Data were drawn from the English longitudinal study of ageing (N~3400). Retrospective information on ACEs was collected in wave3 (2006/07). We calculated a cumulative risk score of ACEs and also assessed distinct dimensions separately. Depressive symptoms were ascertained on eight occasions, from wave1 (2002/03) to wave8 (2016/17). CRP was measured in wave2 (2004/05), wave4 (2008/09), and wave6 (2012/13). The associations of the risk factors with group-based depressive-symptom trajectories and repeated exposure to high CRP (i.e. ⩾3 mg/L) were tested using multinomial and ordinal logistic regression.

RESULTS

All types of ACEs were independently associated with high depressive-symptom trajectories (OR 1.44, 95% CI 1.30-1.60) and inflammation (OR 1.08, 95% CI 1.07-1.09). The risk of high depressive-symptom trajectories (OR 1.47, 95% CI 1.28-1.70) and inflammation (OR 1.03, 95% CI 1.01-1.04) was also higher for participants with higher MDD-PGS. G×E analyses revealed that the associations between ACEs and depressive symptoms were larger among participants with higher MDD-PGS (OR 1.13, 95% CI 1.04-1.23). ACEs were also more strongly related to inflammation in participants with higher CRP-PGS (OR 1.02, 95% CI 1.01-1.03).

CONCLUSIONS

ACEs and polygenic susceptibility were independently and interactively associated with elevated depressive symptoms and chronic inflammation, highlighting the clinical importance of assessing both ACEs and genetic risk factors to design more targeted interventions.

1000 Days: The "WeCare Generation" Program-The Ultimate Model for Improving Human Mental Health and Economics: The Study Protocol

INTRODUCTION

The COVID-19 pandemic stressed the necessity of a new resilience of the human population and health system. The "WeCare Generation" program is a new proposal of territorial intervention, with a new paradigm, on the diseases of the human body and mind.

BACKGROUND

In recent decades, the independent strands of investigation on brain plasticity and early trauma consequences have demonstrated that traumatic experiences in the period from pregnancy to the age of 3 years have an enormous impact on an individual's future development, and both physical and mental health. Research shows that adverse child experiences (ACEs) are associated with a strong risk of conditions such as: harmful alcohol use, smoking, illicit drug use, high body-mass index, depression, anxiety, interpersonal violence, cancer, type 2 diabetes, cardiovascular diseases, stroke respiratory diseases and, as a consequence, to a high financial cost in Italy and also across Europe (1-9% GDP) and the USA (total annual costs estimated to be USD 581 billion in Europe and USD 748 billion in North America). All this suggests that an early intervention on that traumatized-slice of population leads to multiplied savings.

METHODS

A multi-center, randomized, controlled trial was designed. The parents of the future neonatal population (from pregnancy to delivery) with trauma will be enrolled, and randomized to treatment, or control arm. The article describes in detail how the primary outpoint (cost to the national health system), and some secondary outpoints, will be collected.

DISCUSSION

An overall rate of return on investment (ROI) statistically significant 13.0% per annum with an associated benefit/cost ratio (BCR) of 6.3 is expected as the primary outcome of the "WeCare Generation" program. Our proposed model predicts a new medical paradigm aiming to empower new generations, with a strong return on economy and health.

Associations between Adverse Childhood Experiences (ACEs) and Lifetime Experience of Car Crashes and Burns: A Cross-Sectional Study

Unintentional injury is a significant cause of disease burden and death. There are known inequalities in the experience of unintentional injuries; however, to date only a limited body of re-search has explored the relationship between exposure to adverse childhood experiences (ACEs) and unintentional injury. Using a cross-sectional sample of the adult general public (n = 4783) in Wales (national) and England (Bolton Local Authority), we identify relationships between ACE exposure and experience of car crashes and burns requiring medical attention across the life course. Individuals who had experienced 4+ ACEs were at significantly increased odds of having ever had each outcome measured. Furthermore, compared to those with no ACEs, those with 4+ were around two times more likely to report having had multiple (i.e., 2+) car crashes and over four times more likely to report having had burns multiple times. Findings expand the evidence base for the association between ACEs and negative health consequences and emphasise the need for effective interventions to prevent ACEs and their impact on life course health and well-being. Such knowledge can also be used to develop a multifaceted approach to injury prevention.

Development and Validation of the Weighted Index for Childhood Adverse Conditions (WICAC)

BACKGROUND

Adverse experiences in childhood are a major public health concern, promoting social inequality in health through biopsychosocial mechanisms. So far, no known measures comprehend the complexity and variations of severity of adverse events. This study aims to develop and validate a new index: the Weighted Index for Childhood Adverse Conditions (WICAC).

METHODS

The population consists of 7493 randomly invited men and women aged 18-72 years. Data were collected in 2012-2015 as part of the Danish Study of Functional Disorders (DanFunD). Content and construct validation of the WICAC was performed with the hypothesis testing of multiple biopsychosocial outcomes: cardiovascular disease, cancer, poor health, back pain, BMI, obesity, anxiety, depression, low vitality, subjective social status, lower education, smoking, and alcohol consumption. Data were analysed with binominal and linear regression models with risk ratios (RR) and mean differences (MD).

RESULTS

Content validation is fitting for WICAC. The strongest associations observed were for most severe adversity: Poor Health RR = 2.16 (1.19-2.91), Anxiety RR = 3.32 (2.32-4.74), Heavy Drinking RR = 4.09 (1.85-9.04), and Subjective Social Status MD = -0.481 (-0.721-(-0.241)). Similar results were found for the remaining outcomes. Discriminative validation was undecided.

CONCLUSIONS

WICAC is an adequate instrument for measuring cumulative adverse life events in childhood and adolescence for research purposes.

Socioeconomic position and adverse childhood experiences as risk factors for health-related behaviour change and employment adversity during the COVID-19 pandemic: insights from a prospective cohort study in the UK

Background

Non-pharmaceutical interventions to reduce the spread of COVID-19 may have disproportionately affected already disadvantaged populations.

Methods

We analysed data from 2710 young adult participants of the Avon Longitudinal Study of Parents and Children. We assessed the associations of socioeconomic position (SEP) and Adverse Childhood Experiences (ACEs, e.g. abuse, neglect, measures of family dysfunction) with changes to health-related behaviours (meals, snacks, exercise, sleep, alcohol and smoking/vaping), and to financial and employment status during the first UK lockdown between March–June 2020.

Results

Experiencing 4+ ACEs was associated with reporting decreased sleep quantity during lockdown (OR 1.53, 95% CI: 1.07–2.18) and increased smoking and/or vaping (OR 1.85, 95% CI: 0.99–3.43); no other associations were seen between ACEs or SEP and health-related behaviour changes. Adverse financial and employment changes were more likely for people with low SEP and for people who had experienced multiple ACEs; e.g. a history of 4+ ACEs was associated with being furloughed or on other leave during lockdown (OR 1.92, 95% CI: 1.35–2.74).

Conclusions

In this sample of young adults, there was little evidence that lockdown worsened inequalities in health-related behaviours. However, adverse financial and employment consequences of lockdown were more likely to be experienced by people who have already experienced socioeconomic deprivation or childhood adversity, thereby widening social inequalities and demonstrating the need for support into adulthood for those with a history of ACEs.

Adverse childhood experiences and adolescent drug use in the UK: The moderating role of socioeconomic position and ethnicity

Rationale

There is a paucity of prospective UK studies exploring the role of Adverse Childhood Experiences (ACEs) on adolescent teenage drug use and even less is known about the complex interplay between ACEs and adolescent social, demographic, and economic characteristics. To address these gaps, we use rich longitudinal data from the nationally representative Millennium Cohort Study.

Methods

Sex-stratified survey logistic regression modelling was applied using data from 9,476 adolescents and their parents to examine associations between ACEs between ages 3 and 14 years and drug use at ages 14 and 17 years. We a) explore the extent to which associations are robust to adjustment for ethnicity, family income, parental social class, and parental education, b) examine whether associations differ by these factors, and c) estimate the proportion of drug use at ages 14 and 17 years attributable to ACEs after controlling for these factors.

Results

Half of MCS cohort members had been exposed to at least one ACE and approximately 1 in 11 were exposed to 3+ ACEs. Multivariable analyses suggest that ACEs were associated with a higher likelihood of drug use at age 14 than age 17, especially for girls. No evidence was found that either advantaged socio-economic position or ethnicity acted as a buffer against the negative effects of ACEs in relation to adolescent drug use. Finally, we found that prevention of exposure to sexual violence, bullying and violence within the household (if causal) is more important for girls' drug use at age 14 than age 17.

Conclusions

ACEs are associated with adolescent drug use with potential consequences on wider aspects of young people's lives, regardless of their social, ethnic, or economic background, adding further urgency to the need to reduce the incidence of these negative experiences.

An evaluation of a short film promoting kindness in Wales during COVID-19 restrictions #TimeToBeKind

BACKGROUND

In response to successive COVID-19 restrictions in Wales, the Welsh ACE Support Hub launched the #TimeToBeKind campaign in March 2021. The campaign used a short film broadcast on national television and promoted on social media to encourage behaviour change for kindness. We evaluated the #TimeToBeKind campaign film to identify whether watching the film would result in increased intention to act in ways that promote kindness to others and if intentions were associated with being emotionally affected by the film.

METHODS

A mixed methods evaluation was employed, using a short online survey and interaction with the film on the Twitter social media platform. The online survey measured public (n = 390) attitudes towards the film including feelings invoked, and behavioural intentions for acts of kindness as a result of viewing the film. Tweets which interacted with the film (n = 59; likes, re-tweets or comments), and tweet sentiment (positive, negative, or neutral) towards the film were also explored.

RESULTS

The majority of participants reported positive attitudes to the film and agreed that they understood the campaign message (91.8%). 67.9% reported that the film made them feel upset or sad and for 22.6% the film resonated with their lockdown experience. As a result of seeing the film, 63.6% reported intentions to be kinder to others, 65.6% intended to try and help other members of their community, and 70.5% were more likely to check in on friends, family and neighbours. A higher proportion of individuals who were emotionally affected by the film (e.g. upset or sad, hopeful or encouraged, gained something positive) and those for whom the film resonated with their lockdown experience reported increased kindness behavioural intentions as a result of seeing the film.

CONCLUSIONS

Film can be an effective tool to promote behaviour change for kindness. Films that provoke strong emotional reactions can still be perceived positively and lead to behaviour change. With the COVID-19 pandemic accelerating a move online for many, the findings of the present evaluation are relevant to how public health messaging can adapt and utilise this space to target individuals and promote behaviour change.

A Refugee Rose of competencies and capabilities for mental healthcare of refugees

In this paper, I set out the challenges of care for refugees and suggest approaches to assessment and intervention. I discuss clinical interventions that can address the immediate concern of the clinician in a bio-psycho-social framework, and the value of considering eco-social and structural influences that can hinder recovery and perpetuate inequalities. Refugees face multiple adversities before, during and after escaping from life-threatening situations, political violence, torture and persecution. They present with complex health needs and encounter hostility from host countries and public services, which see their needs as an additional demand on the public purse. Regrettably, existing care practice and training of professionals do not often include skills for working across cultures, including cultural formulations and fair assessment, cultural adaptation of interventions, cultural competence and cultural consultation methods, including clinical ethnography and exploration of cultural identity and explanatory models. There are little data on effective and kind models of interpretation and translation. Care systems are rarely designed to fully address the needs of refugees. Health practitioners are not trained to address structural and institutional racism and discrimination, which leads to exclusion of the most marginalised, with little attention to social justice and fair processes as part of appropriate healthcare.

The Contributing Role of Family, School, and Peer Supportive Relationships in Protecting the Mental Wellbeing of Children and Adolescents

Globally, mental disorders are the leading cause of disability in children and adolescents. Previous research has demonstrated that supportive relationships are a key protective factor against poor mental health in children, particularly amongst those who have experienced adversity. However, fewer studies have examined the relative impact of different types of supportive relationships. The current study examined the association between level of family adult support, school adult support, and school peer support and mental wellbeing in a sample of children (age 8-15 years, N = 2,074) from schools in the UK. All three sources of support were independently associated with mental wellbeing. Analyses demonstrated a graded relationship between the number of sources of support and the odds of low mental wellbeing (LMWB), reflecting a cumulative protective effect. While all three sources of support were best, it was not vital, and analyses demonstrated a protective effect of school sources of support on LMWB amongst children with low family support. Peer support was found to be particularly important, with prevalence of LMWB similar amongst children who had high peer support (but low family and school adult support), and those who had high family and school adult support, (but low peer support), indicating that high peer support has an equivalent impact of two other protective factors. Findings from the study highlight the crucial context schools provide in fostering positive peer relationships and supportive teacher-student relationships to promote mental health and resilience for all children, including both those with and without supportive home environments.

The Long-Term Health and Human Capital Consequences of Adverse Childhood Experiences in the Birth to Thirty Cohort: Single, Cumulative, and Clustered Adversity

Human capital-that is the cumulative abilities, education, social skills, and mental and physical health one possesses-is increasingly recognized as key to the reduction of inequality in societies. Adverse childhood experiences have been linked to a range of human capital indicators, with the majority of research in high-income, western settings. This study aims to examine the link between adverse childhood experiences and adult human capital in a South African birth cohort and to test whether associations differ by measurement of adversity. Secondary analysis of data from the Birth to Thirty study was undertaken. Exposure data on adversity was collected prospectively throughout childhood and retrospectively at age 22. Human capital outcomes were collected at age 28. Adversity was measured as single adverse experiences, cumulative adversity, and clustered adversity. All three measurements of adversity were linked to poor human capital outcomes, with risk for poor human capital increasing with the accumulation of adversity. Adversity was clustered by quantity (low versus high) and type (household dysfunction versus abuse). Adversity in childhood was linked to a broad range of negative outcomes in young adulthood regardless of how it was measured. Nevertheless, issues of measurement are important to understand the risk mechanisms that underlie the association between adversity and poor human capital.

Associations between adverse childhood experiences, attitudes towards COVID-19 restrictions and vaccine hesitancy: a cross-sectional study

OBJECTIVES

Adverse childhood experiences (ACEs) can affect life-course health and well-being, including risk-taking behaviour and trust. This study explored associations between ACEs and trust in health information on COVID-19, attitudes towards and compliance with COVID-19 restrictions and vaccine hesitancy.

DESIGN

National cross-sectional telephone survey using a sample of landline and mobile numbers stratified by Health Board, deprivation quintile and age group.

SETTING

Households in Wales during national COVID-19 restrictions (December 2020 to March 2021).

PARTICIPANTS

2285 Welsh residents aged ≥18 years.

MEASURES

Nine ACEs; low trust in National Health Service (NHS) COVID-19 information; supporting removal of social distancing and mandatory face coverings; breaking COVID-19 restrictions; and vaccine hesitancy (rejection or uncertainty of vaccination).

RESULTS

Increasing ACE counts were independently related to low trust in NHS COVID-19 information, feeling unfairly restricted by government and ending mandatory face coverings. High ACE counts (4+ vs 0 ACEs) were also associated with supporting removal of social distancing. Breaking COVID-19 restrictions increased with ACE count with likelihood doubling from no ACEs to 4+ ACEs. Vaccine hesitancy was threefold higher with 4+ ACEs (vs 0 ACEs) and higher in younger age groups. Thus, modelled estimates of vaccine hesitancy ranged from 3.42% with no ACEs, aged ≥70 years, to 38.06% with 4+ ACEs, aged 18-29 years.

CONCLUSIONS

ACEs are common across populations of many countries. Understanding how they impact trust in health advice and uptake of medical interventions could play a critical role in the continuing response to COVID-19 and controlling future pandemics. Individuals with ACEs suffer greater health risks throughout life and may also be excluded from interventions that reduce infection risks. While pandemic responses should consider how best to reach those suffering from ACEs, longer term, better compliance with public health advice is another reason to invest in safe and secure childhoods for all children.

Association of Childhood Adversity With Morbidity and Mortality in US Adults: A Systematic Review

IMPORTANCE

Childhood adversity (CA) is a powerful determinant of long-term physical and mental health that is associated with elevated risk for chronic disease and psychopathology. However, the degree to which CA contributes to mortality as a preventable driver of ill-health and death is unknown.

OBJECTIVE

To estimate the contribution of CA to health behaviors, including smoking and sedentary behavior, as well as the annual mortality attributable to CA in the US through influences on leading causes of death (eg, cardiovascular disease).

EVIDENCE REVIEW

For this systematic review, the PsycINFO and MEDLINE databases were searched on November 15, 2019. The databases were searched for publications from inception (1806 for PsycINFO, 1946 for MEDLINE) to November 15, 2019. Meta-analyses of the associations between CA and morbidity outcomes were included. The population attributable fraction (PAF) was calculated from these associations along with the estimated US prevalence of CA. The PAF was then applied to the number of annual deaths associated with each cause of death to estimate the number of deaths that are attributable to CA. Additionally, the PAF was applied to the incidence of health behaviors to derive the number of cases attributable to CA. Exposure to 1 or more experiences of adversity before the age of 18 years was analyzed, including abuse, neglect, family violence, and economic adversity.

FINDINGS

A total of 19 meta-analyses with 20 654 832 participants were reviewed. Childhood adversity accounted for approximately 439 072 deaths annually in the US, or 15% of the total US mortality in 2019 (2 854 838 deaths), through associations with leading causes of death (including heart disease, cancer, and suicide). In addition, CA was associated with millions of cases of unhealthy behaviors and disease markers, including more than 22 million cases of sexually transmitted infections, 21 million cases of illicit drug use, 19 million cases of elevated inflammation, and more than 10 million cases each of smoking and physical inactivity. The greatest proportion of outcomes attributable to CA were for suicide attempts and sexually transmitted infections, for which adversity accounted for up to 38% and 33%, respectively.

CONCLUSIONS AND RELEVANCE

The results of this systematic review suggest that CA is a leading contributor to morbidity and mortality in the US and may be considered a preventable determinant of mortality. The prevention of CA and the intervention on pathways that link these experiences to elevated disease risk should be considered a critical public health priority.

Health and financial costs of adverse childhood experiences in 28 European countries: a systematic review and meta-analysis

BACKGROUND

Adverse childhood experiences (ACEs) are associated with increased health risks across the life course. We aimed to estimate the annual health and financial burden of ACEs for 28 European countries.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, CINAHL, PsycINFO, Applied Social Sciences Index and Abstracts, Criminal Justice Databases, and Education Resources Information Center for quantitative studies (published Jan 1, 1990, to Sept 8, 2020) that reported prevalence of ACEs and risks of health outcomes associated with ACEs. Pooled relative risks were calculated for associations between ACEs and harmful alcohol use, smoking, illicit drug use, high body-mass index, depression, anxiety, interpersonal violence, cancer, type 2 diabetes, cardiovascular disease, stroke, and respiratory disease. Country-level ACE prevalence was calculated using available data. Country-level population attributable fractions (PAFs) due to ACEs were generated and applied to 2019 estimates of disability-adjusted life-years. Financial costs (US$ in 2019) were estimated using an adapted human capital approach.

FINDINGS

In most countries, interpersonal violence had the largest PAFs due to ACEs (range 14·7-53·5%), followed by harmful alcohol use (15·7-45·0%), illicit drug use (15·2-44·9%), and anxiety (13·9%-44·8%). Harmful alcohol use, smoking, and cancer had the highest ACE-attributable costs in many countries. Total ACE-attributable costs ranged from $0·1 billion (Montenegro) to $129·4 billion (Germany) and were equivalent to between 1·1% (Sweden and Turkey) and 6·0% (Ukraine) of nations' gross domestic products.

INTERPRETATION

Availability of ACE data varies widely between countries and country-level estimates cannot be directly compared. However, findings suggest ACEs are associated with major health and financial costs across European countries. The cost of not investing to prevent ACEs must be recognised, particularly as countries look to recover from the COVID-19 pandemic, which interrupted services and education, and potentially increased risk factors for ACEs.

Perceptions of a short animated film on adverse childhood experiences: a mixed methods evaluation

OBJECTIVES

An evaluation of a short animated film on adverse childhood experiences (ACEs) to explore attitudes and sentiment towards the film including, for a subsample of professionals, associations between attitudes and personal experience of ACEs.

DESIGN

Mixed-method exploratory design.

SETTING

Professionals and the general public.

PARTICIPANTS

A short online survey with 239 professionals. Interaction and user sentiment towards with the film on social media (Twitter, YouTube).

PRIMARY AND SECONDARY OUTCOME MEASURES

Survey: participants' attitudes towards the film including feelings invoked, learning gained and ACE count prevalence. Twitter user and YouTube viewer sentiment (positive, negative or neutral) and interaction (likes, retweets or comments) with the film.

RESULTS

Attitudes to the film were positive: 94.1% and 93.7%, respectively, agreed that it provided a helpful explanation of ACEs and trusted that the film was credible. Of those who reported ACE exposure, 88.9% agreed that those with ACEs would benefit from watching the film. Despite 50.6% reporting that the film had made them feel sad or upset, the majority (66.4%) reported they found the film hopeful or encouraging. Across 358 publicly available tweets from 313 users, 39.1% of tweets expressed positive sentiment, with only 1.4% negative (59.5% neutral). However, there was no association between tweet sentiment and interaction. Thirteen YouTube versions of the film received 171 812 views, 97.3% (n=889/914) ratings were positive (ie, 'thumbs up').

CONCLUSIONS

Despite being emotionally arousing, many professionals reflected positive impacts of the film including a perceived increased ability to discuss ACEs. Public sentiment demonstrated a positive reaction to and acceptability of the film. Understanding the professional and public response to materials developed to increase ACE awareness, such as the film explored here, is important given the growing number of international movements which seek to increase ACE awareness, prevent ACEs and mitigate their lifelong negative effects.

Building Resilience Through Sport in Young People With Adverse Childhood Experiences

Interventions focused on young people at risk of anti-social and criminal behaviour frequently involve physical exercise and/or participation in sporting activities as a primary vehicle to bring about behavioural change in both the short to medium term. Anecdotal evidence suggests that sporting activities positively influence individual well-being alongside a sense of purpose and belonging centred around sporting clubs and activities. Empirically, participation in sport has been identified as a key resilience factor for young people with numerous Adverse Childhood Experiences (ACEs) and investment and policy initiatives target investment in these opportunities. However, the psychological mechanisms which underpin these improvements in well-being and building of resilience are less clearly articulated. This article will review current and developing research in this field to synthesise future applications of sport-related interventions with young people, with a particular emphasis on furthering understanding of the pathways to capacity building at individual and community level which sport and exercise can generate.

The Intersection Between Adverse Childhood Experiences and Environmental Tobacco Smoke in U.S. Households With Children

INTRODUCTION

Environmental tobacco smoke (ETS) is a potent risk factor for secondhand smoke (SHS) exposure. Research reveals, moreover, that children who are exposed to SHS are at an increased risk of disease and premature mortality. Limited research, however, has examined whether households with children experiencing accumulating adverse childhood experiences (ACEs) are also more likely to be characterized by ETS-particularly in the form of family members smoking inside the housing unit.

AIMS AND METHODS

The current study employs a nationally representative sample of 102 341 households with children from the three most recent cohorts of National Survey of Children's Health. Both multinomial logistic regression and a strategic comparison approach are used to examine the association between ACEs and ETS categories.

RESULTS

A large majority of households characterized by ETS report one or more ACEs, while households without ETS are largely void of ACEs. Findings indicate that this association is not merely a function of general family member smoking, as ACEs are strongly and uniquely associated with family smoking inside the housing unit-above and beyond family members smoking more generally.

CONCLUSIONS

Households exhibiting an accumulation of ACEs may benefit from interventions providing resources and education supporting smoke-free home environments. Such families may also be screened and referred through existing family and parenting programs administered in the home environment (eg, home visiting).

IMPLICATIONS

Public health initiatives designed to mitigate child adversities from early life stages may help reduce ETS in housing units-thereby diminishing the risk of secondhand smoke (SHS) exposure among children.

Childhood Emotional Neglect and Adolescent Depression: Assessing the Protective Role of Peer Social Support in a Longitudinal Birth Cohort

Introduction: Childhood adversities have been shown to increase psychopathology risk, including depression. However, the specific impact of childhood emotional neglect on later depression has been understudied. Moreover, few studies have investigated relational protective factors that may offset the risk of depression for children who experienced emotional neglect. Analyzing data (n = 3,265) from the Avon Longitudinal Study of Parents and Children (ALSPAC) study, a longitudinal birth cohort of children born to pregnant women residing in Avon, UK from 1990 to 1992, we assessed the prospective relationship between childhood emotional neglect and depressive symptoms in late adolescence, and tested whether peer social support in mid-adolescence moderates this relationship. Methods: Childhood emotional neglect, defined as the absence of parental attention and support, was measured across seven assessments from age 8 to 17.5. Peer social support was measured at age 15. Depressive symptoms were measured at age 18. We analyzed the associations between emotional neglect and depressive symptoms, and between peer support and depressive symptoms, and also tested interactive effects of peer support on the association between emotional neglect and depressive symptoms. Results: Higher levels of emotional neglect were associated with increased depressive symptoms at 18. Conversely, strong peer social support was associated with reduced depressive symptoms, though no significant interaction with emotional neglect was detected. Conclusion: Although childhood emotional neglect is a risk factor for later depression, our results suggest that strong peer social support at age 15 may generally reduce the risk of depressive symptoms by the time children reach late adolescence. Fostering strong peer support in youth may help offset depression risk for all youth, even among those who have experienced emotional neglect.
