Hypothalamic-pituitary-adrenal axis activation in a high-risk sample of children, adolescents and young adults in residential youth care - Associations with adverse childhood experiences and mental health problems

The time sensitive and dose-responsive association between parental corporal punishment and sleep disturbances in preschoolers: A prospective cohort study

BACKGROUND

To examine whether parental corporal punishment is associated with increased risk of concurrent and later sleep disturbances among preschoolers, and whether the association is time-sensitive or dose-responsive.

METHODS

This 3-year prospective cohort study used data from the Shanghai Children's Health, Education and Lifestyle Evaluation, Preschool(SCHEDULE-P). Participants were newly enrolled preschoolers in November 2016(wave 1) and followed up in April 2018(wave 2) and April 2019(wave 3). Parents reported the children's corporal punishment experiences and sleep disturbances at each wave survey. Children's risk of sleep disturbances in relation to corporal punishment was examined using logistic regression, adjusting for children's age, gender, emotional/behavioral problems, family annual income, and maternal educational level.

RESULTS

The participants of 19,668 children included 9436(47.98 %) females, with a mean age of 3.73(SD = 0.29) years at wave 1. Exposure to corporal punishment was associated with increased odds of concurrent sleep disturbances at wave 1, 2, and 3 (aOR,1.57; 95 % CI, 1.40-1.75; P < .001; aOR,1.60; 95 % CI, 1.43-1.80; P < .001; aOR,1.74; 95 % CI, 1.54-1.95; P < .001), respectively. Exposure to corporal punishment at any wave of preschool was associated with increased odds of sleep disturbances at wave 3, and the risks were greater for proximal and accumulative corporal punishment exposure.

CONCLUSION

There is a time-sensitive and dose-responsive association between corporal punishment and sleep disturbance among preschoolers, with greater risk of sleep disturbances for proximal and accumulative exposure of corporal punishment. Promoting positive parenting strategies and avoiding corporal punishment can be a promising strategy to prevent and intervene sleep disturbances in preschoolers.

Outcomes of adverse childhood experience during late adolescence: Evidence from college and community samples

Scant studies have investigated adverse childhood experience (ACE) outcomes and mastery during adolescence in different cultural contexts. This cross-sectional study examines the impact of ACEs on subjective well-being, health complaints, and healthcare utilization during late adolescence, including the mediating role of the sense of mastery in the Saudi context. Adolescents (N = 396) aged 17-21 years were recruited via convenience sampling from colleges and local communities from two regions in Saudi Arabia. Data were collected using a paper-pencil anonymous survey and analyzed using path analysis. Of the sample, 85.5% experienced at least one ACE. ACEs had a direct effect on subjective well-being (p = 0.034), health complaints (p < 0.001), healthcare utilization (p < 0.001), and sense of mastery (p < 0.001). Sense of mastery had an effect on subjective well-being (p < 0.001) and health complaints (p < 0.001), but not on healthcare utilization (p = 0.436). Sense of mastery partially mediated the relationship between ACEs and subjective well-being (p = 0.034) and health complaints (p < 0.001), but not healthcare utilization (p = 0.438). ACEs have detrimental effects on adolescent health. Attention should be paid to primary prevention and early detection to avoid further harm, and interventions that address the role of the sense of mastery should be developed for adolescents.

Adverse Childhood Experiences and Problematic Cannabis Use: The Role of Emotion Dysregulation and Affective Impulsivity

Problematic cannabis use is highly prevalent among postsecondary students. Consequently, there is a need to examine risk factors associated with problematic cannabis use in this population. The present study investigated whether emotion dysregulation mediates the relationship between adverse childhood experiences (ACEs) and problematic cannabis use, and whether affective impulsivity (negative and positive urgency) uniquely moderates this relationship. Participants consisted of current cannabis users (N = 586) recruited from five universities across Canada. Participants completed an online survey containing self-report measures of ACEs, emotion dysregulation, negative and positive urgency, and problematic cannabis use. Among the sample of postsecondary students, 36% (n = 213) met the threshold for problematic cannabis use. Moderated-mediation analyses revealed that ACEs were positively associated with emotion dysregulation and problematic cannabis use. There was also a significant indirect effect of emotion dysregulation on the association between ACEs and problematic cannabis use at moderate and high (but not low) levels of negative urgency, and at moderate and high (but not low) levels of positive urgency. The moderated-mediation models remained significant when controlling for other facets of impulsivity. Results suggest that elevated levels of emotion dysregulation and urgency are important proximal risk factors for problematic cannabis use among postsecondary students with a history of ACEs. While ACEs cannot be modified given their occurrence in the past, interventions that aim to build mindfulness and adaptive emotion regulation skills may be beneficial for reducing the likelihood that these students will engage in impulsive behaviors, such as cannabis use, when experiencing emotional distress.

Relationship between COVID-related stressors and internalizing symptoms: Gendered neuroendocrine risk profiles

The COVID-19 pandemic generated significant life stress and increases in internalizing disorders. Moreover, COVID-related stressors disproportionately impacted women, consistent with outcomes showing a gender gap in stress-related disorders. Gender-related stress vulnerability emerges in adolescence alongside gender-specific changes in neuroendocrine signaling. Most research on the neuroendocrinology of stress-related disorders has focused on differences in the hypothalamic-pituitary-adrenal (HPA) axis effector hormone cortisol. More recent studies, however, emphasize dehydroepiandrosterone (DHEA), a neuroprotective and neuroactive hormone released concurrently with cortisol that balances its biobehavioral actions during stress. Notably, women show lower cortisol responses and higher DHEA responses to stress. However, lower cortisol and higher DHEA are associated with internalizing disorders in women, while those associations are opposite in men. Thus, gender-specific factors perhaps result in a neuroendocrine profile that places women at greater risk for stress-related disorders. The current study prospectively examined socially evaluated cold-pressor task (SECPT) induced neuroendocrine responses at age 15 and internalizing symptoms during the COVID-19 pandemic at age 21 in a cohort of 175 primarily Black low-socioeconomic status participants, while controlling for internalizing symptoms at age 15. The association between COVID-related stress and internalizing symptoms was not stronger in women. Lower DHEA-cortisol ratios were associated with a weaker relationship between COVID-related stress and internalizing symptoms in women, while higher ratios were associated with a weaker relationship in men. These findings suggest gender differences in the relationship between DHEA and cortisol and internalizing outcomes during a stressful period, and support differential neuroendocrine protective and risk pathways for young men and women.

Adverse Childhood Experiences and alcohol use among U.S.-born and immigrant Latinx youth: the roles of social support and stress hormones

The biobehavioral correlates of Adverse Childhood Experiences (ACEs) among Latinx youth have been strikingly understudied. The purpose of this study was to 1) examine the effects of T-ACEs (e.g., maltreatment, family dysfunction) and E-ACEs (e.g., family deportation, community violence) in alcohol use, 2) test whether social support moderated these associations and 3) explore whether ACEs and alcohol use were related via adrenocortical hormones (i.e., cortisol, dehydroepiandrosterone [DHEA]). A total of 100 Latinx youth, between the ages of 13 and 19, participated in this study (53% female). Community samples of United States (U.S.)-born (N = 54) and immigrant Latinx (N = 46) youth provided morning saliva samples and completed self-report questionnaires. Results highlighted that for immigrant youth, social support buffered the effects of E-ACEs on alcohol use, F(9,89)= 3.34, p = .01, R2 = .25. Although our mediation hypothesis was not supported, the direct effects of T-ACEs (β = .25, t (94) = 2.21, p = .03) and E-ACES (β = -.24, t (94) = -2.23, p = .03) on DHEA were significant for the entire sample. Preventing maltreatment and reducing community-level adversities seem critical for optimal child development, as exposure to these may increase alcohol use risk and affect HPA Axis functioning. Increasing extrafamilial support may be particularly salient for immigrant Latinx youth, as many experience extended immigration-related periods of separation from family members.

Screen use before sleep and emotional problems among adolescents: Preliminary evidence of mediating effect of chronotype and social jetlag

BACKGROUND

Screen use before sleep is shown to be positively related to emotional problems. However, whether this relationship was mediated by circadian phenotypes (i.e., chronotype and social jetlag) remains unclear.

METHODS

Data from two independent adolescent surveys among 2685 and 1368 adolescents, respectively, were used. Adolescents reported screen use before sleep (yes/no and screen time), chronotype, social jetlag, and emotional problems using questionnaires. Serial mediation analyses were performed.

RESULTS

Adolescents who reported screen use before sleep showed later chronotype and greater social jetlag, which was further associated with a higher level of emotional problems. Such relationships held for screen use as a yes/no variable and screen time. The serial indirect effect of chronotype and social jetlag accounted for 6.2%-16.7% of the total effect of screen use before sleep on emotional problems.

LIMITATIONS

The use of a cross-sectional design did not allow the establishment of causal links between the variables. All data were self-reported by adolescents, and might be subject to report bias and recall bias.

CONCLUSIONS

These findings contributed to the existing literature by examining the mediating effect of chronotype and social jetlag in the relationship between screen use before sleep and emotional problems from a circadian rhythm perspective. Healthy media use habits and interventions targeting circadian characteristics may work towards promoting emotional health in adolescents.

Outrunning a bad diet: interactions between exercise and a Western-style diet for adolescent mental health, metabolism and microbes

Adolescence is a period of biological, psychological and social changes, and the peak time for the emergence of mental health problems. During this life stage, brain plasticity including hippocampal neurogenesis is increased, which is crucial for cognitive functions and regulation of emotional responses. The hippocampus is especially susceptible to environmental and lifestyle influences, mediated by changes in physiological systems, resulting in enhanced brain plasticity but also an elevated risk for developing mental health problems. Indeed, adolescence is accompanied by increased activation of the maturing hypothalamic-pituitary-adrenal axis, sensitivity to metabolic changes due to increased nutritional needs and hormonal changes, and gut microbiota maturation. Importantly, dietary habits and levels of physical activity significantly impact these systems. In this review, the interactions between exercise and Western-style diets, which are high in fat and sugar, on adolescent stress susceptibility, metabolism and the gut microbiota are explored. We provide an overview of current knowledge on implications of these interactions for hippocampal function and adolescent mental health, and speculate on potential mechanisms which require further investigation.

Personal Stories of Young Women in Residential Care: Health-Promoting Strategies and Wellbeing

Interdisciplinary social work practice produces and circulates narratives of young women in residential care. The dominant narratives often present negative descriptions of this group, and less attention has been paid to their resistance to these "big stories". This study's aim is to illuminate this resistance of young women in residential care and to explore how they narrate their experiences of being children at risk who have become women managing everyday life. This study utilises a narrative approach and includes three selected personal stories: two from the participants and one from the first author's reflections on resistance. Through contextual analysis at the macro, meso and micro levels, we focus on how personal stories can influence interdisciplinary social work services. We found resistance to dominant narratives on the different levels in the chosen stories. Resistance can create space to reconstruct and renarrate reality together and help understand the meaning and power of storytelling and silence. Participants' resistance can be a tool to rebalance the power between social work practitioners and service users. Based on this analysis, we suggest that interdisciplinary collaborative social work should emphasise service users' personal stories to a higher degree and, in this way, increase user participation in residential care.

Higher hair cortisol concentrations associated with shorter leukocyte telomere length in high-risk young adults

Chronic stress is associated with accelerated biological aging as indexed by short age-adjusted leukocyte telomere length (LTL). Exploring links of biological stress responses with LTL has proved challenging due to the lack of biological measures of chronic psychological stress. Hair cortisol concentration (HCC) has emerged as a measure of chronic hypothalamic pituitary adrenal (HPA) axis activation, allowing the examination of relationships between aggregate cortisol concentrations over time and LTL. Our sample includes 92 participants (38% women, M_age = 26 ± 3.7 years) from a high-risk sample of young adults with previous residential care placements. Two cm hair was collected for HCC, reflecting approximately eight weeks of cortisol secretion. LTL was measured with quantitative polymerase chain reaction (qPCR) in whole blood samples. All samples for LTL were run in triplicate and assayed twice. Linear and polynomial regression models were used to describe the association between HCC and LTL, adjusting for age and sex. HCC and LTL showed negative associations (std. ß = − 0.67, 95% CI [− 0.83, − 0.52], p < .001) in age- and sex-adjusted analyses, indicating that higher HCCs are associated with shorter LTL. Using polynomial regression, we found a curvilinear relationship indicating a stronger negative association at lower cortisol concentrations. Higher HCCs were associated with shorter LTL, supporting the hypothesized involvement of prolonged cortisol secretion in telomere attrition. Thus, HCC may prove useful as a biological indicator of chronic stress associated with aging-related processes in samples exposed to high levels of stress.

Hair cortisol concentrations among urban and rural-dwelling mother-child dyads, La Romana, Dominican Republic

Hair cortisol concentrations (HCC) were studied in mother-child dyads of La Romana, Dominican Republic (DR), a low-income city, and of the surrounding bateyes, sugarcane plantation villages with inhabitants frequently of Haitian descent. Populations of low socioeconomic status (SES) experience hypothalamic-pituitary-adrenal (HPA) axis dysregulation. Urban communities may be increasingly exposed to stressors such as crime and concentrated poverty whereas rural communities may be devoid of important community resources. As a result, the experience of stress in poverty may differ by place of residence. The goal of this study was to examine differences in HCC among urban and rural-dwelling mother-child dyads in socioeconomically disadvantaged communities surrounding La Romana, DR. Forty-five mother/child dyads were enrolled in La Romana and 45 at several bateyes surrounding La Romana. Mothers were ≥18 years and children were between 7 and 14 years. Mothers self-reported perceived stress and demographic factors. Hair samples were collected from mothers and children, and HCC was assessed using enzyme-linked immunosorbent assays. General linear models examined associations between socioeconomic factors and HCC, and between maternal and child HCC. HCC were measured in 88 maternal and 87 child samples (N = 175). Mothers living in a batey had higher HCC than those living in La Romana (p = 0.001). HCC was positively associated among maternal-child dyads (p = 0.001). Further, Haitian-born mothers as a population who frequently live in a rural batey experienced higher HCC (p = 0.025) that may partially be explained by discriminatory practices in the DR. This research helps to elucidate the impact of urban and rural environmental settings on HCC.Lay summaryThis study focuses on chronic stress, measured by hair cortisol levels, among a low-income population of Dominican and Haitian mother-child pairs who live in urban and rural settings. We found that Haitian-born mothers, who frequently live in a rural batey, had higher hair cortisol levels than Dominican born mothers. Hair cortisol levels between mothers and their children were positively associated. This study addresses the impact of urban and rural environments on the stress response among socioeconomically disadvantaged persons living in an upper middle income country who bear an excessive burden of psychosocial stress.

Untangling the relationship between early adversity, placement breakdowns, and obesity in a secure adolescent developmental disorder service: A cross-sectional study

BACKGROUND

Obesity is a growing global health concern, and those with a developmental disorder are at particular risk. Elevated levels of childhood trauma, placement breakdowns and obesity have been documented in the developmental disorder population, yet their relative associations remain unclear.

OBJECTIVE

A previous study (Morris et al., 2020) highlighted a high prevalence of adverse childhood experiences (ACEs) and obesity in adolescents with developmental disorders residing in a secure inpatient setting. The current cross-sectional study sought to further explore the prevalence of placement breakdowns and its relationship with Body Mass Index (BMI) in this sample.

METHODS

Secondary analysis was conducted on existing data for 34 adolescents, aged 10-17 years at admission, held in a secure mental health hospital developmental disorder service in the United Kingdom (UK) under the Mental Health Act.

RESULTS

Almost half of participants had experienced a placement breakdown (47.1%), the majority of whom typically experienced multiple breakdowns (M = 3.94, SD = 2.14). Placement breakdowns significantly predicted BMI and had a predictive effect that was independent to and above that of ACEs.

CONCLUSIONS

Placement breakdowns significantly contribute to risk for obesity, above that explained by early adversity. Those who have experienced placement breakdowns have a greater risk for obesity, irrespective of their level of exposure to ACEs. A history of previous placement breakdowns may act as a red flag for obesity.

[Legal Aspects of Child Protection]

Legal Aspects of Child Protection Several legal codes (e. g. family, social and criminal law) are of importance in child protection cases in Germany. The intention of legal codes differs between family law (relations between family members), social law (support for families) and criminal law (penal aspects). Mental health professionals have to know the prevailing legal norms concerning child-welfare. Collaborative work between medicine and youth welfare and child protection services (CPS) requires a weighing of data protection issues and the risk for the child. German child protection law provides a stepped model for health care professionals to inform CPS. This includes a careful weighing of the risk for child abuse and own competences to provide support. Medical personnel should be aware of several further legislative regulations concerning child protection issues.

The Stress of Caring-Resilience and HPA-Axis Activity in Hair Samples of Youth Residential Caregivers

Background: Professional caregivers in youth residential care institutions experience frequent verbal and physical aggression as well as multiple stressors as part of their everyday work, leading to high levels of burnout and staff turnover. Resilience might buffer against psychophysiological stress response and therefore be crucial for well-being in professional caregivers. Objectives: We aimed to investigate if measures related to resilience [sense of coherence (SoC), self-efficacy and self-care] and attachment security of caregivers were cross-sectionally associated with stress markers in hair samples [cortisol and dehydroepiandrosterone (DHEA)]. Method: Participants (n = 134; 64.2% women) reported on individual resilience measures and provided hair samples for cortisol and DHEA assays. Attachment was assessed in a subsample using the Adult Attachment Projective Picture System (AAP, n = 69). Linear regression models were fitted to estimate the association between resilience measures and the Cortisol:DHEA ratio, cortisol and DHEA, controlling for gender and age. Results: SoC was associated with a lower Cortisol:DHEA ratio (β = -0.36, p < 0.001), driven by a positive association between SoC and DHEA levels (β = 0.28, p = 0.002). Self-care was also associated with lower Cortisol:DHEA ratios (β = -0.24, p = 0.005), due to self-care being associated with higher DHEA (β = 0.21, p = 0.016). HPA-axis measures were not associated with self-efficacy nor with attachment patterns in a subsample. Conclusions: Our findings imply that youth residential care institutions might benefit from programs focusing on enhancing SoC and self-care practices. Fostering a meaningful, comprehensible and manageable professional climate in caregiving environments and implementing self-care in routine practices might enhance not only well-being but also physical health of professional caregivers and in this way buffer adverse health effects of chronic stressors.

Mechanisms of Psychiatric Comorbidities in Epilepsy

Psychiatric illnesses, including depression and anxiety, are highly comorbid with epilepsy (for review see Josephson and Jetté (Int Rev Psychiatry 29:409-424, 2017), Salpekar and Mula (Epilepsy Behav 98:293-297, 2019)). Psychiatric comorbidities negatively impact the quality of life of patients (Johnson et al., Epilepsia 45:544-550, 2004; Cramer et al., Epilepsy Behav 4:515-521, 2003) and present a significant challenge to treating patients with epilepsy (Hitiris et al., Epilepsy Res 75:192-196, 2007; Petrovski et al., Neurology 75:1015-1021, 2010; Fazel et al., Lancet 382:1646-1654, 2013) (for review see Kanner (Seizure 49:79-82, 2017)). It has long been acknowledged that there is an association between psychiatric illnesses and epilepsy. Hippocrates, in the fourth-fifth century B.C., considered epilepsy and melancholia to be closely related in which he writes that "melancholics ordinarily become epileptics, and epileptics, melancholics" (Lewis, J Ment Sci 80:1-42, 1934). The Babylonians also recognized the frequency of psychosis in patients with epilepsy (Reynolds and Kinnier Wilson, Epilepsia 49:1488-1490, 2008). Despite the fact that the relationship between psychiatric comorbidities and epilepsy has been recognized for thousands of years, psychiatric illnesses in people with epilepsy still commonly go undiagnosed and untreated (Hermann et al., Epilepsia 41(Suppl 2):S31-S41, 2000) and systematic research in this area is still lacking (Devinsky, Epilepsy Behav 4(Suppl 4):S2-S10, 2003). Thus, although it is clear that these are not new issues, there is a need for improvements in the screening and management of patients with psychiatric comorbidities in epilepsy (Lopez et al., Epilepsy Behav 98:302-305, 2019) and progress is needed to understand the underlying neurobiology contributing to these comorbid conditions. To that end, this chapter will raise awareness regarding the scope of the problem as it relates to comorbid psychiatric illnesses and epilepsy and review our current understanding of the potential mechanisms contributing to these comorbidities, focusing on both basic science and clinical research findings.
