Adverse Childhood Experiences and Their Impact on Sleep in Adults: A Systematic Review

Childhood Traumas and Depressive Symptoms: The Moderating Role of Anxiety Sensitivity

Purpose

Depression is one of the most common public health problems. Considering the frequency of childhood trauma in people with depressive symptoms, determining mediating factors is important in understanding the relationship between them. Our study aimed to evaluate the mediating effect of anxiety sensitivity, one of the cognitive structures that plays a role in the etiology and maintenance of psychopathologies, on depression symptoms of childhood traumas.

Patients and Methods

The study included 110 participants aged between 18 and 65, diagnosed with depression, and applied to the psychiatry outpatient clinic. Of the participants, 35 were male and 75 were female. The majority of participants were in the 18-25 age group (39.1%), followed by a smaller percentage in the 25-35 age group (32.7%). The Beck Depression Inventory (BDI-I), Childhood Trauma Questionnaire (CTQ), and Anxiety Sensitivity Index (ASI-3) were administered to participants between 15 February and 15 April 2024.

Results

When the sample was examined according to the history of depressive symptoms, it was found that the score of the cognitive subscale of ASI-3 and the scores of the physical neglect, emotional neglect, and emotional abuse subscales of the CTQ were significantly higher in the group with depressive symptoms. When the mediating effect of the scores of "Emotional neglect", "Physical neglect", and "Emotional abuse" subscales of CTQ, and the score of "Cognitive" subscale of ASI-3 score was examined with regression models, it was found that the history of emotional neglect and abuse in childhood predicted depressive symptoms through the cognitive sub-group of AS.

Conclusion

In our study, it was shown that childhood trauma, which could cause a person to evaluate stressful life events as more depressogenic and the formation of negative cognitions about themselves and the world, predicted the severity and occurrence of depressive symptoms through fear of cognitive dysfunction.

A scientometric review of the association between childhood trauma and sleep

Sleep is a complex state which involves interactions between neurophysiological, psychological and neurochemical processes which in turn have an important impact on brain functioning, immune responses, mental health, and quality of life. The incidence of Adverse Childhood Experiences (ACEs) varies across different countries and have been linked with lifespan sleep disturbances with further effects on people's physical and mental health functioning. This review aims to explore the significance of ACE and its impact on sleep by identifying key documents, thematic trends, and knowledge gaps in the literature. A document co-citation analysis of 882 documents from Scopus was conducted to achieve this goal. Research trends focused on the long-term consequences of childhood adverse events with respect to sleep, with emphasis on the role of type, timing and accumulation of these experiences. A recent study has also taken advantage of machine learning and network analysis for discovering essential factors could offer useful information about adults with history of childhood adversity and sleep problems. The studies show unanimously that ACEs are associated with multiple sleep disturbances/disorders which can persist into adulthood, with consequences for suboptimal cognitive and behavioral functioning. Such neurobiological scars can be associated with an increased risk of mental disorders. Future studies are needed that focus on longitudinal analysis of the relationship between early adversity, sleep, and resilience characteristics in adult populations exploring the use of objective assessment measures as well as neurobiological markers.

Association of parental adverse childhood experiences with offspring sleep problems: the role of psychological distress and harsh discipline

BACKGROUND

Sleep problems are common in early childhood and may be affected by parental adverse childhood experiences (ACEs). However, few studies have examined the longitudinal effect of parental ACEs on offspring sleep problems and the underlying mechanism. This study examined parents' psychological distress and harsh discipline (psychological aggression and corporal punishment) as mediators in the longitudinal pathway from parental ACEs to offspring sleep problems.

METHODS

The participants included 617 3-year-old children (mean age of 43.13 months, SD = 3.82) and their parents (mean age of 33.24 years, SD = 4.01) from Wuhu, China. The participants completed an online questionnaire on ACEs, psychological distress, and demographic characteristics in September 2022 (Time 1). Parents completed another online questionnaire in September 2023 (Time 2) on harsh discipline and offspring sleep problems. A path model was used to examine the associations.

RESULTS

Parental ACEs did not directly predict offspring sleep problems. Psychological distress (β = 0.041, 95% CI [0.005, 0.111]) and harsh discipline in the form of psychological aggression (β = 0.019, 95% CI [0.006, 0.056]) separately mediated the relationship between parental ACEs and offspring sleep problems. Psychological distress and psychological aggression also played a serial mediating role in the association of parental ACEs with offspring sleep problems (β = 0.014, 95% CI [0.007, 0.038]).

CONCLUSIONS

Our findings showed the importance of psychological distress and psychological aggression in the intergenerational effect of trauma on offspring sleep problems. Specific interventions aimed at improving mental health and parenting practices should be provided for parents who were exposed to ACEs.

Re-Evaluating Recommended Optimal Sleep Duration: A Perspective on Sleep Literacy

A significant number of adolescents experience sleepiness, primarily due to sleep deprivation. The detrimental effects of inadequate sleep on both physical and mental health are well documented, particularly during adolescence-a critical developmental stage that has far-reaching implications for later life outcomes. The International Classification of Diseases 11th Revision recently introduced the disorder termed 'insufficient sleep syndrome,' characterized by a persistent reduction in sleep quantity. However, diagnosing this condition based solely on sleep duration is challenging due to significant individual variation in what constitutes optimal sleep. Despite this, managing sleep debt remains difficult without a clear understanding of individual optimal sleep needs. This review aims to reassess recommended sleep durations, with a focus on enhancing sleep literacy. Beginning with an exploration of insufficient sleep syndrome, this review delves into research on optimal sleep duration and examines foundational studies on sleep debt's impact on the developing brain. Finally, it addresses the challenges inherent in sleep education programs from the perspective of sleep literacy. By doing so, this review seeks to contribute to a deeper understanding of the chronic sleep debt issues faced by adolescents, particularly those affected by insufficient sleep syndrome.

The Association Between Adverse Childhood Experiences and Sleep in Children with Autism Spectrum Disorder

Children with autism spectrum disorder are at higher risk for adverse childhood experiences (ACEs). They are also more vulnerable to sleep problems and are less likely to obtain the recommended number of hours of sleep than neurotypical children. In the general population, ACEs have been linked to future sleep difficulties. Despite increased vulnerabilities to both ACEs and sleep problems, no study has examined this association in ASD. Using the National Survey of Children's Health across four cohorts, we examined whether ACEs were a risk factor to obtaining the recommended number of hours of sleep, while accounting for demographic and health factors typically associated with sleep duration. Findings indicate that children with ASD with more ACEs were less likely to get the recommended number of hours of sleep than children with fewer ACEs. Other factors associated with sleep included race, anxiety, autism severity, and overall health. These findings indicate that sleep problems in children with ASD are complex and multifaceted. Among other considerations, it is important for clinicians to screen children with ASD for ACEs and consider the possible impact of ACEs on sleep.

Allostasis, health, and development in Latin America

The lifespan is influenced by adverse childhood experiences that create predispositions to poor health outcomes. Here we propose an allostatic framework of childhood experiences and their impact on health across the lifespan, focusing on Latin American and Caribbean countries. This region is marked by significant social and health inequalities nested in environmental and social stressors, such as exposure to pollution, violence, and nutritional deficiencies, which critically influence current and later-life health outcomes. We review several manifestations across cognition, behavior, and the body, observed at the psychological (e.g., cognitive, socioemotional, and behavioral dysfunctions), brain (e.g., alteration of the development, structure, and function of the brain), and physiological levels (e.g., dysregulation of the body systems and damage to organs). To address the complexity of the interactions between environmental and health-related factors, we present an allostatic framework regarding the cumulative burden of environmental stressors on physiological systems (e.g., cardiovascular, metabolic, immune, and neuroendocrine) related to health across the life course. Lastly, we explore the relevance of this allostatic integrative approach in informing regional interventions and public policy recommendations. We also propose a research agenda, potentially providing detailed profiling and personalized care by assessing the social and environmental conditions. This framework could facilitate the delivery of evidence-based interventions and informed childhood-centered policy-making.

Struggling Can Also Show on the Inside: Current Knowledge of the Impact of Childhood Maltreatment on Biomarkers in Mood Disorders

The link between childhood maltreatment and mood disorders is complex and involves multiple bio-psycho-social factors that affect multiple molecular pathways. The present narrative review aims to clarify the current understanding of the impact of childhood maltreatment on biomarkers in patients with mood disorders and their first-degree relatives. Neurotransmitters, such as serotonin, dopamine, norepinephrine, and hormones (eg the stress hormone cortisol), play a crucial role in regulating mood and emotion. Childhood maltreatment can alter and affect the levels and functioning of these neurotransmitters in the brain; further, childhood maltreatment can lead to structural and connectivity changes in the brain, hence contributing to the development of mood disorders and moderating illness presentation and modifying response to treatments. Childhood maltreatment information, therefore, appears mandatory in treatment planning and is a critical factor in therapeutic algorithms. Further research is needed to fully understand these pathways and develop new treatment modalities for individuals with mood disorders who have experienced childhood maltreatment and effective preventive interventions for individuals at risk of developing mood disorders.

The Negative Effects of Travel on Student Athletes Through Sleep and Circadian Disruption

Collegiate athletes must satisfy the academic obligations common to all undergraduates, but they have the additional structural and social stressors of extensive practice time, competition schedules, and frequent travel away from their home campus. Clearly such stressors can have negative impacts on both their academic and athletic performances as well as on their health. These concerns are made more acute by recent proposals and decisions to reorganize major collegiate athletic conferences. These rearrangements will require more multi-day travel that interferes with the academic work and personal schedules of athletes. Of particular concern is additional east-west travel that results in circadian rhythm disruptions commonly called jet lag that contribute to the loss of amount as well as quality of sleep. Circadian misalignment and sleep deprivation and/or sleep disturbances have profound effects on physical and mental health and performance. We, as concerned scientists and physicians with relevant expertise, developed this white paper to raise awareness of these challenges to the wellbeing of our student-athletes and their co-travelers. We also offer practical steps to mitigate the negative consequences of collegiate travel schedules. We discuss the importance of bedtime protocols, the availability of early afternoon naps, and adherence to scheduled lighting exposure protocols before, during, and after travel, with support from wearables and apps. We call upon departments of athletics to engage with sleep and circadian experts to advise and help design tailored implementation of these mitigating practices that could contribute to the current and long-term health and wellbeing of their students and their staff members.

Early adverse childhood experiences and adolescent sleep outcomes

BACKGROUND

Sleep is critical for physical, mental, and emotional health. This may be particularly true for adolescents experiencing rapid physiological changes. Relatively little is known about how adverse childhood experiences (ACEs) are implicated in adolescent experiences with sleep.

OBJECTIVE

We use data (from the Future of Families and Child Wellbeing Study (FFCWS, n = 3444) to assess the relationship between early ACE exposure (by age 5) and various adolescent sleep outcomes. We anticipate that early ACEs will be associated with poor adolescent sleep outcomes.

METHODS

FFCWS data includes survey responses from parents and/or primary caregivers and children at birth and approximately one, three, five, nine, and 15 years later. The FFCWS oversampled unmarried parents with low educational attainment, income, and from marginalized racial-ethnic groups. Models of sleep outcomes included ordinary least squares, Poisson, negative binomial, logistic, and order logistic regression, as appropriate.

RESULTS

Despite a high number of ACEs, adolescent hours of sleep were consistent with published recommendations. Other measures of sleep indicated adolescents in the sample experience worse sleep on most other measures. ACE exposure was associated with difficulty falling asleep and staying asleep. More ACEs was also related with problematic sleep environments (i.e., place slept) and increased snoring. There was some evidence that ACEs were related to less sleep on weekends and increased social jet lag (different patterns of sleep between weekdays and weekends).

CONCLUSIONS

Our findings suggest that ACEs could be important diagnostic data for clinicians in primary care and behavioral sleep medicine practice.

Unveiling hidden dimensions: A novel bifactor approach to unraveling adverse childhood experiences

BACKGROUND

Adverse Childhood Experiences (ACEs) are associated with diverse negative health outcomes and are commonly screened for in primary care, research, and clinical practice. However, more research is needed surrounding the conceptualization, measurement, and application of ACEs measures.

OBJECTIVE

This study examines the bifactor structure and internal reliability of a short, practical, and commonly used ACEs questionnaire and assesses how the factor structure is associated with correlates of ACEs.

PARTICIPANTS AND SETTING

Data from Utah's 2020 Behavioral Risk Factor Surveillance System, a telephone survey assessing the prevalence of health-related behaviors among a sample of adults in Utah (N = 8978, Mage = 51.5, SD = 19.4, Range = 18-99; 50 % female, 87.1 % White) was analyzed.

METHODS

Exploratory and confirmatory factor analyses were conducted to determine the best-fitting factor structure and examined correlations between the identified factors and poor health and substance use with structural equation modeling.

RESULTS

A three-factor bifactor model best fit the data and its components had associations of different direction and magnitude with outcomes (bifactor: health β = 0.83, p < .001, substance use β = 0.14, p = .025; household hardship: health ß = -0.49, p < .001, substance use ß = 0.23, p < .001; general abuse: health ß = -0.63, p < .001, substance use ß = 0.18, p = .036; sexual abuse: health ß = -0.25, p < .001).

CONCLUSIONS

Results highlight the importance of using a bifactor approach to examine and score ACEs measures rather than a traditional total sum score method.

Adverse childhood experiences and depressive symptoms among middle-aged or older adults in China and the mediating role of short sleep duration

BACKGROUND

Limited research has simultaneously examined the link between adverse childhood experiences (ACEs), short sleep duration, and depressive symptoms among middle-aged or older Chinese adults. This study aims to investigate the association between ACEs and later-life depressive symptoms, and to examine the mediating role of short sleep duration (<6 h/night) in this association.

METHODS

Data of 11,452 participants aged ≥45 years were obtained from the China Health and Retirement Longitudinal Study. Information on ACEs, depressive symptoms, and sleep duration were reported via questionnaires. The mediating effect of short sleep duration in the association between ACEs and depressive symptoms was examined by Baron and Kenny's causal steps method and Karlson/Holm/Breen (KHB) method.

RESULTS

Compared to non-exposed group, exposure to ACEs was significantly associated with increased odds of depressive symptoms in a dose-response pattern. The odds ratio of depressive symptoms increased from 1.27 (95 % CI: 1.11-1.46) for one ACE to 3.38 (95 % CI: 2.92-3.90) for ≥4 ACEs. The KHB method identified significant mediating role of short sleep duration in the association between experiencing three or more ACEs and depressive symptoms, with the proportional mediation estimated at 8.96 % and 8.85 % for the groups with 3 ACEs and ≥4 ACEs, respectively. The results were consistent across genders and gender did not moderate these associations.

LIMITATIONS

The cross-sectional design limited the ability to make causal inference.

CONCLUSIONS

ACEs were positively associated with depressive symptoms, and short sleep duration partially mediated this association. Promoting optimal sleep duration among ACE-exposed individuals might improve their mental health.

The association between adverse childhood experiences and insomnia symptoms from adolescence to adulthood: Evidence from the Add Health study

OBJECTIVES

Adverse childhood experiences are potentially traumatic events that occur up to age 17, including abuse, neglect, and household dysfunction. Such trauma often results in chronic stress and poor sleep health, which are linked to negative health outcomes across the lifespan. This study examines the longitudinal association between adverse childhood experiences (ACEs) and insomnia symptoms from adolescence to adulthood.

METHODS

Data from the National Longitudinal Study of Adolescent to Adult Health were used to examine the association between ACEs and insomnia symptoms (trouble falling asleep or staying asleep, dichotomized based on self-reported frequency of 3 times per week or more). We used weighted logistic regression to examine the association between cumulative ACE score (0, 1, 2-3, 4+), 10 specific ACEs, and insomnia symptoms.

RESULTS

Of 12,039 participants, 75.3% experienced at least one adverse childhood experience and 14.7% experienced 4 or more. We found specific adverse childhood experiences, including physical abuse, emotional abuse, neglect, parental incarceration, parental alcoholism, foster home placement, and community violence were associated with experiencing insomnia symptoms throughout the entire 22-year follow-up period from adolescence to mid-adulthood (p < .05), while childhood poverty was only associated with insomnia symptoms in mid-adulthood. The number of adverse childhood experiences showed a dose-response association with insomnia symptoms in adolescence (1 adverse childhood experience: adjusted odds ratio (aOR)=1.47 [1.16, 1.87], 4+ adverse childhood experiences: aOR= 2.76, [2.18, 3.50]), early adulthood (1 adverse childhood experience: aOR= 1.43 [1.16, 1.75], 4+ adverse childhood experiences: aOR= 3.07 [2.47, 3.83]) and mid-adulthood (1 adverse childhood experience: aOR= 1.13 [0.94, 1.37], 4+ adverse childhood experiences: aOR= 1.89 [confidence interval: 1.53, 2.32]).

CONCLUSIONS

Adverse childhood experiences are associated with an increased risk for insomnia symptoms across the lifespan.
