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

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.
