Mental health effects prevalence in children and adolescents during the COVID-19 pandemic: A systematic review

Unlocking NAC's potential ATF4 and m6A dynamics in rescuing cognitive impairments in PTSD

In this study, we investigated the therapeutic potential of N-acetylcysteine (NAC) in a mouse model of post-traumatic stress disorder (PTSD) induced by a single prolonged stress (SPS) protocol. Our findings demonstrate that NAC treatment significantly improved cognitive function and mitigated hippocampal neuronal apoptosis in PTSD model mice. These positive effects were accompanied by a reduction in m6A methylation levels and activating transcription factor 4 (ATF4) expression. Silencing ATF4 further attenuated hippocampal neuronal apoptosis and cognitive dysfunction, while ATF4 overexpression partially reversed the beneficial effects of NAC. It suggests that NAC's efficacy in PTSD may be mediated by its regulation of ATF4 expression and m6A methylation levels. Overall, our study provides valuable insights into the potential mechanism of action for NAC in PTSD treatment, offering promising avenues for future therapeutic strategies.

Initial Results of the Québec Resilience Project (QRP): a Longitudinal and Representative Population-Based Study of Children's Development Prior to and During the COVID-19 Pandemic (2017-2022)

The COVID-19 pandemic instigated changes in almost all aspects of youth's life. While numerous studies have been implemented to understand how these changes are related to youth's development, few concerned large representative samples. This study introduces the methodology and initial results of the Quebec (Canada) Resilience Project (QRP), a representative longitudinal study. The QRP encompassed three phases: (a) 2017 census survey assessing school readiness in kindergarteners before the pandemic (n = 83,335, aged 6 years); (b) 2021 questionnaire study assessing family functioning during COVID-19-related lockdowns (n = 4524, aged 10 years); and (c) 2022 questionnaire survey assessing children's school performance and mental health post-lockdowns (n = 8217, aged 11 years). In total, 3871 children were assessed either by parents or teachers in the three phases. We explored factors associated with children school performance (maths, reading, and writing) and mental health (emotional, withdrawal, hyperactivity/impulsivity/inattention, and conduct problems symptoms). Population weights were estimated from census data to maintain the representativeness of the population. School readiness vulnerability in kindergarten and parental anxiety and depression during lockdowns were associated with both children's lower school performances and higher levels of all mental health symptoms post-lockdown. Loss in family income and parental difficulties in maintaining work-life balance during lockdowns were associated with children's lower school performance and higher levels of some mental health symptoms (emotional and hyperactivity/impulsivity/inattention) post-lockdown. The results underscore that pandemic-related disruptions were negatively associated with children's school performance, emphasizing the need for interventions in the school environment. Associations between pandemic-related disruptions and children mental health were less consistent yet emphasize the importance of parental mental health.

The Relationship Between Self-Control and Non-Suicidal Self-Injury in Adolescent Psychiatric Outpatients: Exploring the Role of Self-Control

BACKGROUND

Non-suicidal self-injury (NSSI) is a significant public health concern that threatens the physical and mental health of adolescents. Given its high prevalence among adolescents, understanding the characteristics and contributing factors of NSSI is crucial. This study aimed to characterize NSSI and examine the relationship between self-control and NSSI among adolescent psychiatric outpatients.

METHOD

This study was conducted in a psychiatric department of a hospital in Hubei Province, China, involving 206 adolescent psychiatric outpatients (135 females, 12-18 years old). Assessments included the Ottawa Self-Injury Inventory (OSI), the Self-Control Scale (SCS), and a self-designed sociodemographic questionnaire.

RESULT

In this sample, 77.18% reported a history of NSSI. The prevalence of NSSI was significantly higher in females than in males (χ2 = 19.059, p < 0.01). The NSSI group had significantly lower self-control scores compared to the non-NSSI group (F = 27.458, p < 0.01). In the NSSI group (n = 156), self-control was negatively associated with NSSI frequency and fully mediated by NSSI function.

CONCLUSIONS

These findings highlight the complete mediating role of NSSI function between self-control and NSSI frequency, offering insights for future prevention and intervention efforts.

Psychiatric hospitalizations among adolescents during the pandemic in Italy: a retrospective study

OBJECTIVES

The COVID-19 pandemic has negatively impacted child and adolescent mental health. The study outcome was the evaluation of the pandemic impact on adolescents' hospitalizations in an acute psychiatric ward.

METHODS

With an observational and retrospective design, we collected selected variables among adolescents hospitalized in an acute psychiatric ward from 01/07/2017 to 30/06/2022. Data were statistically processed.

RESULTS

Our sample consisted of 118 minors with an average age of 15.7 ± 1.2 SD, mostly represented by females (61 %) and Italians (60.2 %), who made 204 hospitalizations in the study period. The admissions by years drastically decreased in 2020 concomitantly with the lockdown and increased in the first half of 2022. The admission rate was higher in winter and spring, except in 2020 when all admissions decreased (p=0.000). Females more frequently were hospitalized for suicidal behavior and acute anxiety (p=0.000) and were discharged with acute stress reactions, eating disorders, and mood disorder diagnoses (p=0.000). Differently, males more frequently were hospitalized for aggressive behavior (p=0.000) and discharged with ADHD diagnosis (p=0.000). At multiple linear regression, the duration of hospitalization (dependent variable) was negatively associated with "the pandemic period" (p=0.017) and "absent aggressive behavior" (p=0.003), and positively with "autism" diagnosis (p=0.000).

CONCLUSIONS

We highlighted the more stressful impact of COVID-19 pandemic on female adolescents, who required more frequently psychiatric hospitalizations due to suicidal behavior, anxiety and mood disorders.

Exploring adolescent suicide attempts before and during the coronavirus disease 2019 pandemic: a cross-sectional study

OBJECTIVE

The objective of this study was to analyze suicide attempts in adolescents treated in the emergency department before and during the coronavirus disease 2019 pandemic.

METHODS

This cross-sectional, documentary, and retrospective study assessed the medical records of adolescents treated for suicide attempts in two emergency rooms linked to a teaching hospital in São Paulo, Brazil. Data were collected from the pre-pandemic period (between January 1, 2015, and March 10, 2020) and the pandemic period (between March 11, 2020, and May 5, 2023), characterizing the adolescents, risk factors for suicide attempts during the pandemic, and treatment. Data were subjected to descriptive and inferential analyses, including association tests and trend analysis, with a p-value of <0.05 considered statistically significant. The national ethical guidelines were followed.

RESULTS

Data on 140 suicide attempts were collected, of which 54 occurred during the pandemic. The trend in these cases remained stable (p>0.05). We observed an association between adolescents who had completed high school and cases during the pandemic, with a previous mental disorder diagnosis and pre-pandemic cases, and a higher number of suicide attempt notifications to the Brazilian epidemiological surveillance system during the pandemic period (p<0.05). Feelings of loneliness were the most prevalent risk factor during the pandemic.

CONCLUSIONS

The COVID-19 pandemic did not show an influence on the number of suicide attempt cases in adolescents. However, it was observed that the cases during this period were not related to previous mental disorder diagnoses, as seen in the pre-pandemic period, which may suggest that other risk factors were associated with suicide attempt cases during the pandemic.

A Snapshot of Peer Relationships in Children and Youth: Pre- Versus During COVID-19

Strong peer relationships are an essential component of a healthy, happy, and long lifetime. Given that there is little understanding of the impact of COVID-19 on peer relationships, this study explored the effects of the COVID waves on peer relationships for clinically referred children and youth while controlling for age, sex, and income. 11,281 children and youth between the ages of 4 and 18 years, who were receiving services from mental health agencies across Ontario from January 2018-March 2022, were assessed using the interRAI ChYMH. Chi-square tests of independence and logistic regression analysis was performed. Overall, as expected, there were significantly fewer peer relationship difficulties during COVID-19 compared to the pre-pandemic period. Despite the general decline of peer issues, individuals between the ages of 8-18, particularly males, were more likely to experience peer relationship difficulties compared to those 4-7 years old. Additionally, children from the lowest income households experienced greater peer relationship difficulties during COVID-19 when compared to those from the highest income households. The findings from this study demonstrate the nuanced changes in social behaviours due to the ongoing pandemic for children and youth and highlight those youth who are most in need of social and behavioural interventions.

Unraveling the complexities of adolescent depression: A call for action

The adolescent years are a period of profound change, both physically and psychologically. For many, these years are marked by excitement and exploration, but for others, they are fraught with challenges that can lead to significant mental health issues. Depression, in particular, has become an increasingly prevalent concern among adolescents worldwide, and its multifaceted etiology requires a comprehensive approach to understanding and intervention. A recent study on the relationships among negative life events, dysfunctional attitudes, social support, and depressive symptoms in Chinese adolescents offers valuable insights into the complex interplay between various factors contributing to adolescent depression. The authors explore a moderated mediation model to better understand how these factors interact with and contribute to the onset of depression. This article aims to delve into the key findings of the study, highlight its implications for clinical practice, and encourage further research in this critical area.

Feasibility study of the e-learning version of the "Journey of the Brave:" a universal anxiety-prevention program based on cognitive behavioral therapy

BACKGROUND

School-based cognitive behavioral therapy (CBT) programs could contribute toward preventing anxiety disorders in children. However, setting aside class time for such programs is difficult. Internet-based CBT (I-CBT) is an efficient way to provide CBT. However, studies on I-CBT for anxiety prevention remain scarce, including I-CBT for school-based universal prevention programs. Therefore, we developed an e-learning version of a school-based anxiety-prevention CBT program, "Journey of the Brave," which was effective in Japan, to make it more flexible and accessible. This study evaluated its feasibility.

METHODS

We conducted a single-arm study based on 44 parents and children. Children aged 10-12 years took the e-learning program at home. Parents and children responded to a questionnaire three times: before the learning (Pre), after the learning (Post), and three months later (FU: Follow-up). Feasibility was comprehensively evaluated through dropout rates, satisfaction and learning records, and changes in scores on psychological scales assessing anxiety symptoms, emotion-regulation skills, and children's emotional and behavioral problems.

RESULTS

Of the 44 children, 42 started the e-learning, and 32 continued it (dropout rate of 23.8%). Furthermore, 83.9% of the children and 96.8% of the parents responded "agree" or "somewhat agree" regarding overall satisfaction. The parent-rated Spence Children's Anxiety Scale(SCAS) (SCAS-P) showed a significant decrease between Pre and FU (p = 0.014, 95% CI = (-9.22, -0.84)); however, the child-rated SCAS (SCAS-C) reduction was not significant (p = 0.08). The Emotion‑Regulation Skills Questionnaire (ERSQ) also increased significantly between Pre and FU (p = 0.045, 95% CI = (0.18, 18.31)). The Total Difficulties Score of the Strengths and Difficulties Questionnaire(SDQ) decreased significantly from Pre to Post (p = 0.025, 95% CI = (-3.62, -0.19)); however, it was not significantly different between Pre and FU (p = 0.67).

CONCLUSION

The e-learning version showed low dropout rates and high satisfaction ratings from parents and children. Moreover, this study did not rule out the possibility that the program reduced children's anxiety and improved their emotional-regulation skills. Therefore, its potential and feasibility were indicated.

Effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents

OBJECTIVE

The daily lives of adolescents have changed significantly because of COVID-19 pandemic. We investigated the effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents.

METHODS

Data from the 2021 Korea Youth Risk Behavior Survey were used. In total, 54,848 survey participants were included in the analysis. Allergic diseases included allergic rhinitis, atopic dermatitis, and asthma. Changes attributed to COVID-19 included family economic difficulties, physical activity, breakfast skipping frequency, alcohol consumption, smoking, and depressive moods. Chi-square tests and multiple logistic regression analyses were conducted to examine the impact of changes in daily life attributed to COVID-19 on allergic diseases.

RESULTS

Among the Korean adolescents surveyed, 29.8% experienced a deterioration in their economic status due to COVID-19, 49.1% reported decreased physical activity, 2.8% reported increased alcohol consumption, 1.0% reported an increase in their smoking behavior, and 36.9% reported an increase in depressive moods. Those diagnosed with atopic dermatitis, allergic rhinitis, or asthma within the previous 12 months accounted for 17.1%, 6.2%, and 1.0% of the population, respectively. Adolescents who were significantly affected by COVID-19 in their daily lives were frequently diagnosed with allergic diseases within the last 12 months.

CONCLUSION

Changes in daily life due to COVID-19, including decreased physical activity and increased depressive mood, were common in adolescents and were associated with an increased prevalence of allergic diseases. Since changes in daily life due to the pandemic may increase the burden of allergic disease, additional interventions for disease management should be considered.

Exploring the Feasibility of a Cancer Awareness Program for High School Students in a Brazilian School: A Pilot Study

Cancer is a leading cause of mortality globally and is projected to be the primary cause of death in Brazil by 2030. Yet, for high school students, information and understanding about cancer are primarily offered through standard biology lessons. This study aimed to assess the feasibility of a brief educational intervention related to cancer among high school students in a Brazilian private school. Participants attended a 1-h online session regarding different aspects of cancer. A self-reported questionnaire about the main topics addressed in the session was filled out before [pre] and after [post] the educational intervention and the results were compared by McNemar's chi-square test. From 900 parents invited, 44 (4.9%) responded to the invitation and agreed with their children's participation, and 24 students attended the activity. The questionnaire was easy to fill out for the students and allowed us to measure differences after the educational intervention. The high school students considered the most interesting topics cancer myths and protective/risk factors. The project was feasible and showed easy application and better knowledge after the educational intervention. The main challenge is related to the access to parents to authorize their children's participation. Designing interventions that focus on cancer education might be a viable way to increase prevention and early diagnosis with implications for students, their families, and the community.

Associations of adverse childhood experiences with depression and anxiety among children in the United States: Racial and ethnic disparities in mental health

OBJECTIVE

To assess associations of ACEs with depression and anxiety, with special emphasis on potential racial and ethnic disparities.

METHOD

Data were from the National Survey of Children's Health (NSCH), 2021-2022, a large, cross-sectional, nationally representative, population-based study of United States children aged 0-17. The associations of cumulative ACEs with depression and anxiety among 104,205 children and adolescents were assessed via multivariable logistic regression, including adjustment for age, sex, race, household income, and parental educational attainment.

RESULTS

ACEs were associated with depression and anxiety in a linear, dose-dependent manner. After adjustment for covariates, compared to no ACE exposures, participants with exposures to one, two, and three ACEs exhibited significantly higher odds of depression (fully-adjusted ORs and 95 % CIs = 2.18 [2.03, 2.35], 4.95 [4.55, 5.39], and 11.39 [10.18, 12.75], respectively). For anxiety, compared to no ACEs exposures, participants with exposure to one, two, and three ACEs had significantly higher odds of anxiety (fully-adjusted ORs and 95 % CIs = 1.90 [1.81, 2.00], 3.66 [3.44, 3.90], and 6.91 [6.30, 7.58], respectively). Notably, stratified analyses indicated potential effect modification by race, wherein the associations of ACEs with depression and anxiety were strongest in Black and White participants.

CONCLUSION

ACEs were robustly associated with depression and anxiety in a national sample of U.S. children and adolescents, with differential impacts of ACES on mental health observed across racial and ethnic groups. These findings underscore the need for urgent government and healthcare interventions and policies to ameliorate ACEs' health effects, especially among disproportionately impacted minority groups.

Psychological Interventions and Those With Elements of Positive Psychology for Child and Youth Mental Health During the COVID-19 Pandemic: Literature Review, Lessons Learned, and Areas for Future Knowledge Dissemination

BACKGROUND

There was a marked decline in child and teenage mental health worldwide during the pandemic, with increasing prevalence of depression, anxiety, and suicide. Research indicates that positive psychological interventions may be beneficial for mental health.

OBJECTIVE

The aims of this review were to evaluate positive psychological interventions for child and youth mental health implemented during the COVID-19 pandemic and assess overall effectiveness for mental health and knowledge.

METHODS

We undertook a literature search of PubMed, MEDLINE, and Google Scholar for all eligible studies on digital and hybrid in-person psychological interventions for youth mental health during the COVID-19 pandemic. A particular emphasis was placed on positive psychological interventions or interventions that had components of positive psychology, including gratitude, acceptance, positive emotions, or resilience building.

RESULTS

A total of 41 interventions were included in this review. Most of the interventions were digital. Overall, most of the interventions assisted with one or more mental health or psychological indicators, such as depression, anxiety, posttraumatic stress disorder, stress, and resilience. However, findings were mixed when it came to targeting both depression and anxiety together. The interventions that promoted youth mental health most often had a range of diverse positive psychology components and were evidence based. Not all studies measured changes in mindfulness. Few studies examined knowledge acquired on mental health self-care, managing mental health problems, knowledge of positive psychological techniques, mindfulness knowledge, or mental health self-efficacy.

CONCLUSIONS

Diverse multicomponent interventions appear to assist with youth mental health overall, although their effects on both depression and anxiety are less clear. There is also a need for more research on knowledge gains to determine whether the interventions improved knowledge on mental health-supportive behaviors, which may be sustained beyond the intervention. Finally, more studies need to evaluate whether the interventions assisted with increasing self-efficacy for practicing positive psychological techniques as well as changes in mindfulness levels. Future studies should not only assess effectiveness for mental health outcomes but also assess knowledge translation, with valid measures of knowledge and self-efficacy for mental health-supportive behaviors and positive psychological skills acquired (eg, the ability to practice mindfulness).

The Impact of COVID-19 on Neuropsychological and Emotional-Behavioural Development in a Group of 8- and 9-Year-Old Children

Introduction: The rapid spread of the COVID-19 pandemic has had a significant impact on the psychological well-being of millions of people around the world, and even more so among children. Contracting SARS-CoV-2, resulting in home confinement and restrictions on daily and school activities, led to negative effects on the mental health of the paediatric population. Although children suffering from COVID-19 had milder general symptoms compared to adults, impairments in cognitive, neuropsychological, and emotional-behavioural development were noted. Objective: The main aim of the present study was to detect possible changes in the neuropsychological and emotional-behavioural development of children after infection with the SARS-CoV-2 virus. The second aim was to investigate possible relationships between cognitive abilities and psychosocial characteristics. Methods: A total of 40 patients aged 8-9 years were recruited and divided into two groups: children who contracted (CG) and did not contract (NCG) SARS-CoV-2. The BVN 5-11 (Neuropsychological evaluation battery for developmental age from 5 to 11 years) instrument was administered to assess attention, memory, verbal recall, planning, phonemics, and categorical fluency domains in the paediatric population. Data on changes in emotional-behavioural profile and daily activities were collected through a questionnaire to parents. Results: The Wilcoxon signed-rank test revealed a significant change in mood after the COVID-19 period only in the CG participants (p = 0.019). However, the neuropsychological performance of the two identified groups on BVN 5-11 sub-items was below the cutoff of clinical significance. Correlations were found between sub-items of the BVN 5-11 battery, extracurricular activities, and children's psycho-motor development. Significant positive correlations were observed between Naming on visual presentation and Reading time (p = 0.006), backward digit span and time of motor activity (p = 0.009), Visual attention and Reading time (p = 0.048), and Phonemic fluency and time observed using devices (p = 0.030). Positive statistically significant correlations were also found between Mood and Free behaviour (p = 0.000), between Mood and Structured behaviour (p = 0.005), and between Mood and peer Interaction (p = 0.013). Conclusions: SARS-CoV-2 infection negatively affected the emotional development of children contracting the virus. The neuropsychological functioning of the paediatric population was influenced by psychosocial variables and time spent on daily activities, which played a protective role in children's cognitive development.

Adolescents Hospitalized in an Acute Psychiatric Ward: The Difference between Males and Females in the Pre- and Pandemic/Post-Pandemic Periods

(1) Background: The pandemic lowered by 10% the psychological wellness among adolescents worldwide. (2) Methods: This observational retrospective study compared the demographic and clinical variables of male and female adolescents hospitalized in an acute psychiatric ward during the pre-pandemic, from 1 July 2017 to 28 February 2020, and the pandemic/post-pandemic, from 1 March 2020 to 30 June 2023. (3) Results: In total, 153 adolescents of 15.8 years on average (±1.14 DS) were more frequently hospitalized (n = 131, 54.4%) in the pre-pandemic than in the pandemic/post-pandemic (n = 110, 45.6%), but female hospitalizations increased in the post-pandemic more than male hospitalizations (62.9% vs. 37.1%) (Pearson Chi2 = 8.54, p = 0.003); in the pandemic/post-pandemic, we reported increased aggressive behavior and schizophrenia spectrum and emotional disorders in males, whereas in females, depressive and emotional disorders were prevalent; more adolescents previously treated in Child Mental Health Services were hospitalized in the pandemic/post-pandemic period; and males hospitalized in the study period reported higher Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) scores. (4) Conclusions: In the pandemic/post-pandemic, females more frequently required hospitalizations for depressive behavior and males for aggressive behavior and schizophrenia spectrum disorders, whereas, in both males and females, hospitalizations due to emotional disorders increased. Our results suggest the need for mental health prevention in adolescents, who represent the most vulnerable population in the case of disaster.

Suicidal ideation in Chinese adolescents: prevalence, risk factors, and partial mediation by family support, a cross-sectional study

Background

Suicidal ideation is a pressing public health concern, particularly among adolescents. The objective of this study was to examine the prevalence of and factors associated with suicidal ideation in Chinese adolescents, addressing an important gap in current research.

Methods

This study employed an online survey of 3443 adolescents in Lianyungang, using a cross-sectional design. The assessment included the use of the Patient Health Questionnaire-9, the seven-item Generalized Anxiety Disorder instrument, and the Perceived Social Support Scale to evaluate suicidal ideation, anxiety symptoms, and social support in adolescents, respectively.

Results

In adolescents, the prevalence of suicidal ideation was 22.1%, with a significantly higher proportion among female adolescents than among males (27.9% vs 16.9%, P < 0.001). Binary regression analysis identified (OR = 1.788, 95% CI: 1.467-2.177, P < 0.001), anxiety symptoms (OR = 10.035, 95% CI: 7.441-13.534, P < 0.001), total PHQ-9 scores of mothers (OR = 1.040, 95%CI: 1.003 - 1.078, P = 0.034), total GAD-7 scores of mothers (OR = 0.958, 95%CI: 0.919 - 0.998, P = 0.039), and moderate parental relationships (OR = 2.042, 95% CI: 1.630-2.557, P < 0.001) to be risk factors for suicidal ideation; family support was a protective factor (OR = 0.888, 95% CI: 0.859-0.918, P < 0.001). Furthermore, family support partially mediates the relationship between anxiety symptoms and suicidal ideation among adolescents (9.28%).

Conclusions

This study highlights high adolescent suicidal ideation rates and recommends gender-specific interventions, anxiety management, and family support for improvement in mental health status.

Comparison of antipsychotic drug use in children and adolescents in the Netherlands before and during the COVID-19 pandemic

This study aims to describe the patterns and trends in antipsychotic prescription among Dutch youth before and during the corona virus disease 2019 (COVID-19) pandemic (between 2017 and 2022). The study specifically aims to determine whether there has been an increase or decrease in antipsychotic prescription among this population, and whether there are any differences in prescription patterns among different age and sex groups. The study utilized the IADB database, which is a pharmacy prescription database containing dispensing data from approximately 120 community pharmacies in the Netherlands, to analyze the monthly prevalence and incidence rates of antipsychotic prescription among Dutch youth before and during the pandemic. The study also examined the prescribing patterns of the five most commonly used antipsychotics and conducted an autoregressive integrated moving average (ARIMA) analysis using data prior to the pandemic, to predict the expected prevalence rate during the pandemic. The prescription rate of antipsychotics for Dutch youth was slightly affected by the pandemic, with a monthly prevalence of 4.56 [4.50-4.62] per 1000 youths before COVID-19 pandemic and 4.64 [4.59-4.69] during the pandemic. A significant increase in prevalence was observed among adolescent girls aged 13-19 years. The monthly incidence rate remained stable overall, but rose for adolescent girls aged 13-19 years. Aripiprazole, and Quetiapine had higher monthly prevalence rates during the pandemic, while Risperidone and Pipamperon had lower rates. Similarly, the monthly incidence rates of Aripiprazole and Olanzapine went up, while Risperidone went down. Furthermore, the results from the ARIMA analysis revealed that despite the pandemic, the monthly prevalence rate of antipsychotic prescription was within expectation. The findings of this study suggest that there has been a moderate increase in antipsychotic prescription among Dutch youth during the COVID-19 pandemic, particularly in adolescent females aged 13-19 years. However, the study also suggests that factors beyond the pandemic may be contributing to the rise in antipsychotic prescription in Dutch youth.

Adolescents' Mental Health Concerns in Pre- and During COVID-19: Roles of Adverse Childhood Experiences and Emotional Resilience

Limited research has explored the trend of adolescent mental health concerns pre- and during the COVID-19 pandemic and how such mental health concerns are explained by emotional resilience and Adverse Childhood Experiences (ACEs). The purpose of this study is to investigate the prevalence and severity of mental health concerns among U.S. adolescents and examine the mediating role of emotional resilience in the relationship between ACEs and mental health concerns (i.e., anxiety and depression). Using the 2018-2021 National Survey of Children's Health, we analyzed a large sample of 12-17 aged adolescents. Descriptive statistics of the prevalence and severity of mental health concerns were conducted. Further, four separate mediation analyses were conducted to examine the association between ACEs, emotional resilience, and mental health concerns for each year. Two key findings are as follows. First, the prevalence and severity of mental health concerns have shown an upward trend across pre- and during COVID-19. Second, all paths in the mediation models were found to be statistically associated with one another over four years. We used parents' reports for variables of interest; further we used a single item to capture emotional resilience. This study not only demonstrates the trend of adolescent mental health concerns before and during COVID-19 but also highlights the crucial role of emotional resilience as a mediator of ACEs and mental health concerns. Findings emphasize the imperative for prevention and intervention efforts to strengthen adolescents' emotional capacity to cope with childhood adversities and additional life challenges.

Adherence of Brazilian Minors to the 24-Hour Movement Guidelines after In-Person School Return

The levels of adequacy of movement behaviors after returning to in-person school activities following the COVID-19 pandemic are not yet well understood. This study aimed to assess the adherence of Brazilian minors to the recommendations of the 24-Hour Movement Guidelines (moderate to vigorous physical activity, recreational screen time, and sleep duration), as well as overall adherence to these guidelines, after the relaxation of COVID-19 social isolation measures and the resumption of in-person schooling. A cross-sectional study was conducted with parents or guardians (39 ± 7.8) of minors aged up to 18 years of age (3.8 ± 2.5). A total of 172 individuals responded to the questionnaire. Data were compared with those obtained in the Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic. There was an 18.6 percentage decrease (p-value < 0.001) in overall adherence to the 24-Hour Movement Guidelines when comparing the periods before the COVID-19 pandemic (March 2020) and after the return to in-person schooling (March 2021). The largest percentage drop in adherence between these periods was observed for moderate to vigorous physical activity (27.4%; p-value < 0.001) and the lowest for sleep (10.5%; p-value < 0.001). Adherence to the 24-Hour Movement Guidelines did not return to pre-pandemic levels with the resumption of in-person school activities.

Physical activity and mental health trends in Korean adolescents: Analyzing the impact of the COVID-19 pandemic from 2018 to 2022

Objective

Mental health significantly affects the physical and emotional development of adolescents. The aim of the current study was to examine how physical activity (PA) and mental health among Korean adolescents changed before and after the start of the COVID-19 pandemic.

Methods

We used comparative cross-sectional methods, gathering information from the Korea Disease Control and Prevention Agency databases and conducting Chi-square testing and correlation analysis for evaluation.

Results

The findings indicate that before and during the pandemic, participation in both moderate- and high-intensity PA, as well as strength training, mitigated stress, depression, and suicidal ideation. Furthermore, the findings confirm the beneficial effects of various physical activities on mental well-being.

Conclusions

These insights emphasize the vital role of regular PA in improving mental health among adolescents, particularly during a health crisis such as the pandemic.

Omega-3 alleviates behavioral and molecular changes in a mouse model of stress-induced juvenile depression

Introduction

Depression is increasingly diagnosed in adolescence, necessitating specific prevention and treatment methods. However, there is a lack of animal models mimicking juvenile depression. This study explores a novel model using ultrasound (US) stress in juvenile mice.

Methods

We employed the US stress model in one-month-old C57/BL6 mice, exposing them to alternating ultrasound frequencies (20-25 kHz and 25-45 kHz) for three weeks. These frequencies correspond to negative and neutral emotional states in rodents and can induce a depressive-like syndrome. Concurrently, mice received either an omega-3 food supplement (FS) containing eicosapentaenoic acid (EPA; 0.55 mg/kg/day) and docosahexaenoic acid (DHA; 0.55 mg/kg/day) or a vehicle. Post-stress, we evaluated anxiety- and depressive-like behaviors, blood corticosterone levels, brain expression of pro-inflammatory cytokines, and conducted metabolome analysis of brain, liver and blood plasma.

Results

US-exposed mice treated with vehicle exhibited decreased sucrose preference, a sign of anhedonia, a key feature of depression, increased anxiety-like behavior, elevated corticosterone levels, and enhanced TNF and IL-1β gene expression in the brain. In contrast, US-FS mice did not display these changes. Omega-3 supplementation also reduced anxiety-like behavior in non-stressed mice. Metabolomic analysis revealed US-induced changes in brain energy metabolism, with FS increasing brain sphingomyelin. Liver metabolism was affected by both US and FS, while plasma metabolome changes were exclusive to FS. Brain glucose levels correlated positively with activity in anxiety tests.

Conclusion

Chronic omega-3 intake counteracted depressive- and anxiety-like behaviors in a US model of juvenile depression in mice. These effects likely stem from the anti-inflammatory properties of the supplement, suggesting potential therapeutic applications in juvenile depression.

Suicidal ideation and suicide attempts among students aged 12 to 24 after the lifting of COVID-19 restrictions in China: prevalence and associated factors

Objective

To investigate the prevalence and associated factors of suicidal ideation and suicide attempts among adolescent and young adults in China from December 14, 2022 to February 28, 2023, when COVID-19 restrictions were lifted.

Methods

Students in middle and high schools and colleges and universities in the province of Sichuan, China were asked to complete on-line cross-sectional surveys. Information was collected about sociodemographics, experiences related to the COVID-19 pandemic, suicidal ideation and suicide attempts. Participants also filled out the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7 and the Social Support Rate Scale surveys. Factors associated with suicidal ideation or suicide attempts were explored using logistic regression.

Results

Of the 82,873 respondents (aged 12 to 24 years), 21,292 (25.7%) reported having thought of suicide at least once in their lifetime, 10,382 (12.5%) reported having thought about suicide within the previous 12 months, and 1,123 (1.4%) reported having attempted it within the previous 12 months. Risk of lifetime suicidal ideation was higher among middle school students than among older students. Risk of suicidal ideation and risk of suicide attempts correlated directly with severity of symptoms of depression and anxiety, and inversely with level of social support. Greater risk of suicidal ideation and suicidal attempts was associated with: being female, living in an urban environment, attending a boarding school, currently being in love, having parents who divorced or remarried, having parents who exhibit non-authoritative parenting behavior, having higher family income, having been COVID-19 infected, having been quarantined for a long time, and being dissatisfied with one's education.

Conclusions

Suicidal ideation and suicide attempts remain prevalent among young people in China. The potential associated factors identified in our study may be useful for targeting appropriate psychosocial interventions and developing mental health policies.

School-Based Tele-Behavioral Health: A Scoping Review of the Literature

BACKGROUND

Telehealth utilization exploded during the COVID-19 pandemic, including within school-based health programs. School-based tele-behavioral health can help programs overcome barriers of access to care, but the current state and effectiveness of such programs are unknown.

METHODS

A scoping literature review was conducted. Studies were included if they described in-school behavioral health services delivered via telehealth for children ages 5 to 18. From the included studies, population, location, setting, intervention, telehealth modality, clinician type, and outcomes assessed were extracted.

FINDINGS

Eighteen studies met inclusion criteria. All described psychotherapy or medication management delivered by psychologists (n = 7) and/or psychiatrists (n = 11). Treatment included psychotherapy (N = 8), psychiatric consultation (N = 7), medication management (N = 4), crisis stabilization (N = 1), and caregiver education (N = 1). Eight studies provide qualitative or quantitative outcomes, with 4 examining clinical effectiveness.

CONCLUSIONS

Despite limited findings in the literature, school-based tele-behavioral health is feasible, effective, and acceptable for delivery of behavioral health care to children and adolescents.

It's all in the hair: Association between changes in hair cortisol concentrations in reaction to the COVID-19 pandemic and post-traumatic stress symptoms in children over time

After exposure to a stressful/traumatic event, some individuals will develop post-traumatic stress symptoms (PTSS). In adults, low cortisol levels appear to be a risk factor for the development of PTSS. Indeed, both lower pre-trauma cortisol levels and low cortisol levels in the aftermath of a traumatic event have been associated with greater PTSS. In contrast, studies conducted in children showed that elevated cortisol levels shortly after trauma exposure are associated with more severe post-traumatic stress symptomatology. The few studies that have examined how pre-trauma cortisol levels predict PTSS in children have found no effect. Given that a pandemic can induce PTSS in certain individuals, we investigated whether cortisol secretion prior to and in the early stages of the COVID-19 pandemic in Quebec (Canada) predicted PTSS in children. In June 2020, we collected a hair sample from 71 children (8-15 y/o, M = 11.65; 54.93% girls) without a history of psychopathology or exposure to previous traumatic events. Hair samples allowed us to derive cumulative measures of cortisol levels for the months prior to (from mid-December 2019 to mid-March 2020) and at the beginning of the pandemic (from mid-March 2020 to mid-June 2020). PTSS were assessed every 3 months between June 2020 (T1) and March 2021 (T4). The results showed that a greater increase in hair cortisol at the beginning of the pandemic predicted less PTSS at T1, with an increase in these symptoms over time. This study highlights the utility of using hair cortisol during future chronic stressful events to better understand its association with the evolution of distress.

Caregiver and Child Mental Health During 3 Years of the COVID-19 Pandemic

BACKGROUND AND OBJECTIVES

Coronavirus disease 2019 (COVID-19) lockdowns (stay-at-home orders) had significant mental health consequences in 2020 to 2021 for caregivers and children. Little is known about "postlockdown" periods in 2022 to 2023. We investigated the mental health experiences of Australian families throughout the 3 years of the COVID-19 pandemic (2020-2023), by demographic characteristics and lockdown length.

METHODS

A total N = 12 408 caregivers (N = 20 339 children, aged 0-17 years) completed Australia's only representative, repeated, cross-sectional, National Child Health Poll across 6 waves (June 2020-April 2023). Caregivers reported mental health for themselves (Kessler-6, poor versus not) and each child (self-rated mental health, poor/fair versus good/very good/excellent), and perceived impacts of the pandemic on own/child mental health (negative versus none/positive). Binary logistic models were fitted to predict marginal probabilities of each mental health measure by state/territory group (proxy for lockdown length), over time, adjusted for potential demographic confounders.

RESULTS

Poor caregiver Kessler-6 was similar between genders but more common for sole caregivers, and those with a home language other than English and lower education. Poor/fair child self-rated mental health was similar between genders and increased with child age. Perceived negative impacts were more common for females and socially advantaged caregivers. Overall, negative mental health experiences increased with lockdown length, peaking with the height of lockdown in July 2021, before declining.

CONCLUSIONS

Negative mental health experiences of Australian caregivers and children decreased during postlockdown periods of 2022-2023; however, social gradients persisted. These data can inform more precise mental health policies that enable better use of limited mental health infrastructure.

Inter-relationships between suicidality and depressive symptoms among children and adolescents experiencing crisis: A network perspective

OBJECTIVES

Suicidality and depressive symptoms have emerged as major mental health issues reported among children and adolescents experiencing crises. In light of these concerns, this study was conducted to elucidate interrelationships between depressive symptoms and suicidality at an item level within this population during the COVID-19 pandemic, a worldwide public health crisis affecting children and adolescents.

METHOD

A cross-sectional study design was used. Primary and secondary school students completed the Children's Depression Inventory - Short Version (CDI-S) and two standard suicidality questions tapping suicidal ideation and suicide plans, respectively. A network analysis was performed to examine inter-connections between depressive symptoms and suicidality.

RESULTS

A total of 5380 students participated in the study. Prevalence of suicidal ideation and suicide plans were 12.8 % (95 % CI = 11.9 %-13.7 %) and 9.9 % (95 % CI = 9.2 %-10.8 %), respectively; the prevalence of depressive symptoms was 41.2 % (95%CI = 39.8 %-42.5 %). The network analysis identified CDI4 (self-hatred) as the most influential node with the highest centrality, followed by CDI8 (loneliness), CDI5 (crying), and CDI1 (sadness). Additionally, CDI5 (crying), CDI1 (sadness), CDI4 (self-hatred), and CDI10 (feeling unloved) were the most meaningful nodes linking depressive symptoms with suicidality.

CONCLUSIONS

Critical depressive symptoms linked with suicidality among children and adolescents living through the COVID-19 pandemic included self-hatred, loneliness, crying, and sadness. Interventions that target these depressive symptoms may have increased utility in reducing the risk of suicidality within this population.

Neuropsychological Symptoms and Quality of Life during the COVID-19 Pandemic in Children: A Survey in a Pediatric Population in the Abruzzo Region, Italy

BACKGROUND

The SARS-CoV-2 pandemic has significantly affected the pediatric population. Long-term sequelae (Long COVID-19) may particularly involve the central nervous system, with possible effects on psychological well-being and quality of life (QoL), aspects that were already influenced by the restrictive measures and general social impact of the pandemic.

METHODS

We conducted a cross-sectional survey that aims at investigating the neuropsychological effects and the QoL impairment of SARS-CoV-2 on a cohort of children and adolescents in the Abruzzo region (Italy). A questionnaire was submitted to caregivers with the help of the PEDIATOTEM platform. A control group of healthy subjects was also included to distinguish between the effects of infection from the general influence of the pandemic.

RESULTS

A total of 569 subjects responded: 396 COVID-19 patients (99 of whom had Long COVID-19) and 111 controls. After the pandemic, when compared with the COVID-19 group, the controls reported significantly increased appetite, sleeping habits, and time spent remotely with friends and a reduction in physical activity and time spent in person with friends. A significant higher rate of controls asked for psychological/medical support for emotional problems. On the other hand, the Long COVID-19 group showed more fatigue and emotional instability with respect to non-Long-COVID-19 subjects. No differences in QoL results (EuroQOL) were found between the COVID-19 patients and controls, while the Long-COVID-19 subgroup showed significantly higher rates of pain/discomfort and mood instability, as confirmed by the analysis of variation of responses from the pre-COVID-19 to the post-COVID-19 period.

CONCLUSIONS

Among COVID-19 patients, neuropsychological and QoL impairment was more evident in the Long COVID-19 subgroup, although emotional and relational issues were also reported by uninfected patients, with a growing request for specialist support as a possible consequence of social restriction.

The evidence-based COPE program: Reducing the time between diagnosing and treating depression and anxiety in youth

ABSTRACT

The soaring prevalence of depression and anxiety in children, teenagers, and young adults is now a public health epidemic, yet access to timely evidence-based mental health treatment is often lacking due to a severe shortage of mental health providers. This article provides an overview of the current state of depression and anxiety in children and adolescents as well as first-line evidence-based treatment. The Creating Opportunities for Personal Empowerment (COPE) program, a cognitive-behavioral skills-building intervention, is highlighted as an evidence-based intervention for timely treatment that can be delivered by NPs, physicians, and physician associates/assistants in primary care settings, school-based health centers, and chronic care clinics with reimbursement as well as in schools and universities as a preventive mental health intervention.

Psychological Experiences of Parents of Pediatric Cancer Patients during and after COVID-19 Pandemic

BACKGROUND

Family members dealing with the devastating impact of a cancer diagnosis are now facing even greater vulnerability due to the COVID-19 pandemic. Alongside the already overwhelming trauma, they must also bear the distressing burden of the infection risks. The purpose of this study was to examine and explore the effects in parents of pediatric cancer patients two years after the start of the COVID-19 pandemic to compare these data with the previous data.

METHODS

We conducted a single-center prospective observational study, enrolling 75 parents of 42 pediatric oncology patients. Four questionnaires (IES-R; PSS; STAI-Y and PedsQL) were given to the parents 2 years after the first evaluation.

RESULTS

The bivariate matrix of correlation found a strong significant positive correlation between IES-R and PSS scores (r = 0.526, p < 0.001) as in T1. Stress symptoms (t = 0.00, p < 0.001) and levels of anxiety (trait) (t = 0.32, p < 0.001) remained unchanged; anxiety state levels appeared to have increased (t = 0.425, p < 0.001); there was a significant decrease in the PedsQL tot (t = 5.25, p < 0.001).

CONCLUSIONS

The COVID-19 pandemic has influenced the levels of stress and anxiety of parents and the quality of life of patients, also correlating with the traumatic impact of the diagnosis.

Implementation of a Childcare-Based Obesity Prevention Program for Vulnerable Families During the COVID-19 Pandemic: Lessons for School Nurses

COVID-19 brought significant changes to the role of school nurses, necessitating the development of remote health education programs. However, there is a lack of evidence and pedagogical lessons for digitally transforming education for socially vulnerable children. This qualitative study analyzes the health educational needs and barriers faced by children and service providers in a childcare-based obesity prevention program during the pandemic in South Korea. Through a thematic content analysis, four core themes emerged: (a) heightened concerns about obesity and the pandemic's impact on facilities, (b) unexpected positive outcomes of the program, (c) digital readiness gaps, and (d) insufficient program satisfaction (better than nothing). When designing a digital-based health education program for vulnerable children, assessing individual readiness and facility suitability is crucial. Additionally, school nurses should incorporate hybrid pedagogy, integrating technology-mediated activities. By leveraging technology effectively and considering individual and environmental factors, educators can provide comprehensive and accessible health education.

Risk Factors and Trends in Adolescent's Suicide Attempt Rates Before and After the Coronavirus Disease 2019 Pandemic

BACKGROUND

Understanding adolescents' mental health during the coronavirus disease 2019 (COVID-19) pandemic and identifying those most at risk is an urgent public health challenge. This study explored the trend of suicide attempts and the association between loneliness, family financial stress, and suicide attempts during the COVID-19 pandemic among adolescents.

METHODS

Data of the 2020 to 2022 Korea Youth Risk Behavior Surveys for adolescents aged 13-18 years were used. Multivariate logistic regression analyses were performed to examine the association between suicide attempts, family financial stress, and loneliness during the COVID-19 pandemic.

RESULTS

The trend of suicide attempt rates was lowest in 2020 (1.9%, 1,034 out of 53,534) and it showed an increasing trend with rates of 2.2% (1,159 out of 53,445) in 2021 and 2.5% (1,271 out of 50,455) in 2022. The risk of suicide attempt was higher among adolescents who experienced financial stress (in 2020: adjusted odds ratio [AOR], 1.53, 95% confidence interval [CI], 1.26-1.88; in 2021: AOR, 1.63, 95% CI, 1.03-1.54) and felt lonely (in 2020: AOR, 2.19, 95% CI, 1.78-2.70; in 2021: AOR, 2.65, 95% CI, 2.16-3.26; in 2022: AOR, 1.3, 95% CI, 1.04-1.55) than those who did not.

CONCLUSION

The COVID-19 pandemic affected the suicide attempts of adolescents, with financial stress and feelings of loneliness closely linked to this impact. Although the pandemic nears its end, the persistent risk of suicide attempts among adolescents remains a concern. Therefore, it is imperative to implement targeted screening and interventions to address adolescent suicide risk.

School children's mental health during the COVID-19 pandemic

Introduction

The COVID-19 pandemic significantly impacted the daily routines of children, with social distancing and quarantine leading to reduced social interactions and potential increased conflicts within families. These factors can increase the risk for anxiety and depression while reducing overall quality of life.

Methods

Our study included 1843 school children aged 8 to 12 from 56 schools over a 2.5-year period before and during the pandemic. This multi-wave cross-sectional study utilized baseline data from an optimization trial of an indicated preventive intervention. The main outcomes were self-reported symptoms of anxiety and depression, and quality of life was the secondary outcome measure. Furthermore, responses to COVID-relevant questions were measured using a self-composed scale. Our objectives were to compare anxiety and depression symptom levels between cohorts of children who participated in the study before and during the pandemic, to examine if anxiety or depression predicted the COVID response, and whether anxiety and depression and subtypes of anxiety had an impact on quality of life during the pandemic. Linear regression and interaction models were used to examine relevant associations.

Results

Levels of anxiety and depression were higher in all waves compared to pre-pandemic levels. Quality of life was lower during the pandemic than before the pandemic, particularly among children with generalized anxiety symptoms. Quality of life was negatively associated with loneliness.

Discussion

Our study revealed that children reported higher anxious and depressive symptoms during the pandemic compared to pre-pandemic levels, as well as reduced quality of life. Lockdowns and restrictions may have contributed to this burden. Additionally, self-reported loneliness was a significant possible consequence of the restrictive measures imposed on children during the pandemic. Additional research is needed to investigate the long-term effects of the pandemic on children, particularly regarding the stability of elevated levels of anxiety and depression. Such studies could examine whether these conditions are indicative of a trajectory toward more severe internalizing disorders.Clinical trial registration: NCT04263558.

Mental health in the COVID-19 pandemic: A longitudinal analysis of the CLoCk cohort study

BACKGROUND

Little is known about the long-term mental health consequences of the pandemic in children and young people (CYP), despite extremely high levels of exposure to the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus and the disruption to schooling and leisure activities due to the resultant restrictions. There are mixed findings from systematic reviews of how the pandemic affected CYP's mental health, which may be due to heterogeneous methods and poor quality studies. Most, but not all, suggest deterioration in mental health but population level studies may obscure the differing experiences of subgroups. The study questions are: (i) are there subgroups of CYP with distinct mental health profiles over the course of the second year of the Coronavirus Disease 2019 (COVID-19) pandemic (between April 2021 and May 2022); and (ii) do vulnerability factors influence CYP's mental health trajectories.

METHODS AND FINDINGS

A matched longitudinal cohort study of non-hospitalised test-positive and test-negative 11- to 17-year-old CYP in England were recruited from the UK Health Security Agency having undergone PCR testing for COVID-19. They completed the Strengths and Difficulties Questionnaire (SDQ) at least twice over a 12-month follow-up period. Overall, 8,518 of 17,918 (47.5%) CYP who returned their first SDQ at 3 or 6 months post-testing were included in the analytical sample. Associations between age, sex, ethnicity, socioeconomic status (SES), and an educational health and care plan (EHCP, indicating special educational needs) on SDQ score trajectories were examined separately, after adjusting for PCR test result. Findings from multilevel mixed-effects linear regression model showed that on average mental health symptoms as measured by the total SDQ score increased over time (B = 0.11 (per month), 95% CI = 0.09 to 0.12, p < 0.001) although this increase was small and not clinically significant. However, associations with time varied by age, such that older participants reported greater deterioration in mental health over time (B = 0.12 (per month), 95% CI = 0.10 to 0.14 for 15 to 17y; 0.08 (95% CI = 0.06 to 0.10) for 11 to 14y; pinteraction = 0.002) and by sex, with greater deterioration in girls. Children with an EHCP experienced less deterioration in their mental health compared to those without an EHCP. There was no evidence of differences in rate of change in total SDQ by ethnicity, SES, or physical health. Those with worse prior mental health did not appear to be disproportionately negatively affected over time. There are several limitations of the methodology including relatively low response rates in CLoCk and potential for recall bias.

CONCLUSIONS

Overall, there was a statistically but not clinically significant decline in mental health during the pandemic. Sex, age, and EHCP status were important vulnerability factors that were associated with the rate of mental health decline, whereas ethnicity, SES, and prior poor physical health were not. The research highlights individual factors that could identify groups of CYP vulnerable to worsening mental health.

Olfactory Epithelium Infection by SARS-CoV-2: Possible Neuroinflammatory Consequences of COVID-19

Background

The loss of smell is a typical diagnostic symptom of coronavirus disease 2019 (COVID-19). This sensorial deprivation may be expressed as quantitative (anosmia or hyposmia) or qualitative (dysosmia) alterations as a consequence of anatomical disturbances of the nasal epithelium structure. The olfactory system sends direct neuronal connections to brain structures that are involved in emotional processing, including deep temporal nuclei. This anatomical and functional feature may be related to the occurrence of emotional disorders among COVID-19 patients.

Summary

We identify a possible sequence of events, from typical olfactory dysfunction that is associated with COVID-19 and caused by olfactory epithelium damage to disturbances in the quality of life and emotional state of infected patients that is attributable to possible neuroinflammatory processes. Sensorial deprivation causes deleterious actions on mood, negatively affecting quality of life. Olfactory dysfunction that is associated with COVID-19 occurs concurrently with psychological distress, symptoms of anxiety, and depressive disorders and impinges on self-perceived quality of life.

Key Messages

Changes in mood are certainly associated with multiple factors, including the environment and isolation, but the observation that the virus may penetrate the central nervous system through the olfactory bulb and the connection between the olfactory system and prefrontal and orbitofrontal cortices and the amygdala-hippocampus do not allow one to discard neural factors that are involved in the pathophysiology of emotional symptoms in post-COVID-19 patients. Behavioral symptoms of COVID-19 involve local olfactory actions and the participation of central neuronal systems.

Pandemic life in families with health anxiety symptoms, parental perspectives

Background

The covid-19 pandemic has influenced children and parents worldwide. The pandemic has also been suggested to especially affect and exacerbate health anxiety (HA) symptoms in children and adolescents. However, there is limited understanding of the potential mechanisms challenges of families where parents themselves experience mental health issues such as high degree of HA symptoms.

Objective

The aim of this study was to explore parental experiences of pandemic life in families with continuously high levels of HA symptoms during the covid-19 pandemic.

Method

Six parents, identified with high levels of HA symptoms, participated in qualitative individual semi-structured interviews. Interviews were analysed according to Interpretative Phenomenological Analysis principles.

Results

Three main themes emerged. Theme 1) "Anxious children in a pandemic world" explores how pandemic - independent child factors including anxious temperament may have influenced the child pandemic experience. Theme 2) "Parental influences on child anxiety" describes parental reflections on their possible influence on child anxious thoughts. Theme 3) "Living with pandemic guidelines and restrictions" demonstrates the varying parental experiences of interventions and how these may affect HA thoughts.

Conclusion

Parents who themselves experience HA symptoms see their children, who also experience HA symptoms, to be particularly susceptible and vulnerable to both content and rhetoric of pandemic information. These children may however, experience school lockdown to be anxiety relieving. Parents who themselves have illness-related fears may not see themselves as perpetuating for their child's anxious thoughts.

Reduced Psychosocial Well-Being among the Children of Women with Early-Onset Breast Cancer

BACKGROUND

Approximately 27% of female breast cancer patients are diagnosed before the age of 55, a group often comprising mothers with young children. Maternal psychosocial well-being significantly impacts these children's psychosocial well-being. This study assesses the well-being of children with mothers who have early-onset breast cancer.

METHODS

We examined the eldest child (up to 15 years old) of women with nonmetastatic breast cancer (<55 years old, mean age: 40) enrolled in the mother-child rehab program 'get well together'. Using maternal reports on children's well-being (the Strengths and Difficulties Questionnaire; SDQ), we describe the prevalence of abnormally high SDQ scores and identify protective and risk factors via linear regression.

RESULTS

The mean SDQ scores of 496 children (4-15 years old, mean age: 8) fell below the thresholds, indicating psychosocial deficits. However, most SDQ scores deviated negatively from the general population, especially for emotional problems, with one in ten children displaying high and one in five displaying very high deficits. Female sex, more siblings, a positive family environment and maternal psychosocial well-being were protective factors for children's psychosocial well-being.

CONCLUSIONS

Children of mothers with breast cancer may benefit from improved maternal well-being and family support. Further research is needed to identify appropriate interventions.

Parental anxiety and depression are associated with adverse mental health in children with special needs during the COVID-19 pandemic

Introduction

The coronavirus disease 2019 (COVID-19) pandemic has led to restrictions in various areas of life, including social life, work, leisure, health, and education. Vulnerable groups, such as children with special needs and their parents, may be at increased risk of experiencing exacerbated mental health problems during stressful periods such as the COVID-19 lockdowns.

Materials and methods

Telephone interviews were conducted with 954 parents of children with special needs. We assessed parental levels of generalized anxiety and depression using the validated GAD-7 and PHQ-8 scales. Parents were asked to rate family burden and their worry about the COVID-19 crisis, as well as their children's adverse mental health symptoms and health behaviors. Parents also reported their children's worries about the COVID-19 crisis. We conducted regressions to examine the relationship between parents' mental health problems and their children's adverse mental health symptoms and health behaviors. Qualitative data from open-ended questions were coded thematically and major themes of parental worry about the COVID-19 crisis were identified.

Results

Parental anxiety and depression symptoms predicted adverse mental health symptoms and behaviors in children with special needs. Criteria for current depression were met by 7.9% of parents of children with special needs, whereas 4.7% of the general population in Vorarlberg met the criteria for current depression according to data from the Austrian Health Interview Survey in 2019. Parental self-ratings of both depression and anxiety were highly correlated. The majority of parents reported being burdened (79.1%) or worried (67.8%) about the COVID-19 crisis. The main themes of parental worry about the COVID-19 crisis included COVID-19 infection (40.6%), economic situation (13.1%), uncertainty (8.4%), lack of social contact with family and friends (8.1%), family health status (7.5%), and school life (7.5%).

Discussion

Mental health symptoms in parents of children with special needs were strongly associated with increased adverse mental health symptoms and health behaviors in their children. Parents of children with special needs were more likely to be depressed during the COVID-19 pandemic than adults in 2019. We call for additional mental health support to reduce the mental health burden in families with children with special needs.

Impact of COVID-19 on the mental health of children and young people: an umbrella review

BACKGROUND

Over the past 3 years, a multitude of studies have highlighted the impact of the COVID-19 pandemic on the mental health of children and young people (CYP). In this umbrella review, we synthesise global evidence on the impact of COVID-19 on the mental health of CYP from existing systematic reviews with and/or without meta-analysis.

METHODS

Adopting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we evaluated 349 citations and identified 24 eligible reviews with medium to high methodological quality to be reviewed narratively.

RESULTS

Most of the reviews reported a high prevalence of anxiety disorders, depression, suicidal behaviour, eating disorders and other mental health problems. Most studies that used data at multiple time points indicate a significant increase in mental health problems in CYP, particularly in females and older adolescents.

CONCLUSIONS

Multipronged psychosocial care services, policies and programmes are needed to alleviate the burden of mental health problems in CYP as a consequence of the COVID-19 pandemic and associated global health measures.

Anxiety, self-efficacy, and their determinants in school students during the COVID-19 pandemic: a survey in Southeastern Iran

BACKGROUND

The COVID-19 pandemic has been linked to various psychological disorders, including anxiety, particularly among the general public. It is crucial to monitor the mental health of school students, who are considered a vulnerable group in society, and assess their self-efficacy, as it can significantly affect their mental health. This study aimed to investigate the levels of anxiety and self-efficacy among school students during the COVID-19 pandemic.

METHODS

This cross-sectional study utilized convenience sampling to examine a sample of 335 school students from Sistan and Baluchestan province in southeastern Iran. An online questionnaire, distributed through social media platforms, was used to collect data. The questionnaire included demographic information, COVID-19 related items, the Multidimensional Anxiety Scale for Children-MASC, and the Self-Efficacy Questionnaire for Children-SEQ-C. Data analysis was conducted using IBM SPSS version 24, with a significance level set at < 0.05.

RESULTS

The study revealed a significant negative correlation between children's anxiety and self-efficacy (r = -0.23, P < 0.001). Several factors were identified as predictors of anxiety, including low self-efficacy (β = -0.29, P < 0.001), female gender (β = 0.27, P < 0.001), concern about family members contracting COVID-19 (β = 0.18, P < 0.001), persistent advice of others to adopt preventive measures (β = 0.14, P < 0.005), level of education (β = -0.12, P < 0.017), and perceived risk of COVID-19 infection (β = -0.11, P < 0.030). These variables collectively accounted for 17% of the variance in anxiety.

CONCLUSION

The findings of the study highlight the importance of addressing the mental health of school students, specifically their anxiety levels, during epidemics. The results also indicate that enhancing self-efficacy among students during a pandemic could be a beneficial strategy for promoting their mental health.

SARS-CoV-2 sero-immunity and quality of life in children and adolescents in relation to infections and vaccinations: the IMMUNEBRIDGE KIDS cross-sectional study, 2022

PURPOSE

The study evaluates the effects on sero-immunity, health status and quality of life of children and adolescents after the upsurge of the Omicron variant in Germany.

METHODS

This multicenter cross-sectional study (IMMUNEBRIDGE Kids) was conducted within the German Network University Medicine (NUM) from July to October 2022. SARS-CoV-2- antibodies were measured and data on SARS-CoV-2 infections, vaccinations, health and socioeconomic factors as well as caregiver-reported evaluation on their children's health and psychological status were assessed.

RESULTS

497 children aged 2-17 years were included. Three groups were analyzed: 183 pre-schoolchildren aged 2-4 years, 176 schoolchildren aged 5-11 years and 138 adolescents aged 12-18 years. Positive antibodies against the S- or N-antigen of SARS-CoV-2 were detected in 86.5% of all participants (70.0% [128/183] of pre-schoolchildren, 94.3% of schoolchildren [166/176] and 98.6% of adolescents [136/138]). Among all children, 40.4% (201/497) were vaccinated against COVID-19 (pre-schoolchildren 4.4% [8/183], schoolchildren 44.3% [78/176] and adolescents 83.3% [115/138]). SARS-CoV-2 seroprevalence was lowest in pre-school. Health status and quality of life reported by the parents were very positive at the time of the survey (Summer 2022).

CONCLUSION

Age-related differences on SARS-CoV-2 sero-immunity could mainly be explained by differences in vaccination rates based on the official German vaccination recommendations as well as differences in SARS-CoV-2 infection rates in the different age groups. Health status and quality of life of almost all children were very good independent of SARS-CoV-2 infection and/or vaccination.

Prevalence and impact of psychiatric disorders on hospitalized pediatric patients with chronic pancreatitis

BACKGROUND

Patients with chronic pancreatitis (CP) often have a debilitating clinical course characterized by high disease burden, and poor quality of life and these factors adversely affect mental health. However, there is paucity of literature on the prevalence and impact of psychiatric disorders on hospitalized pediatric patients with CP.

METHOD

ology: We analyzed the Kids Inpatient Database, and National Inpatient Sample, between 2003 and 2019 and included patients up to 21 years of age. Pediatric CP patients with psychiatric disorders were compared with patients without any of the psychiatric disorders using the ICD diagnostic codes. Various demographic and clinical factors were compared between the groups. Length of hospitalization and total hospital charges were used as surrogates to compare the hospital resource utilization between the groups.

RESULTS

We analyzed a total of 9,808 hospitalizations with CP and the overall prevalence rate of psychiatric disorders was 19.8%. The prevalence rate increased from 19.1% in 2003 to 23.4% in 2019, p = 0.006. The peak prevalence rate of 37.2% was noted at 20 years of age. Depression was noted at 7.6% of the total hospitalizations followed by substance abuse (6.5%), and anxiety (4.4%). Multivariate linear regression analysis showed that among CP patients, psychiatric disorders were independently associated with 1.3 additional days of stay and incurred $15,965 higher charges.

CONCLUSIONS

The prevalence of psychiatric disorders is increasing in pediatric CP. The concomitant presence of psychiatric disorders was found to be associated with prolonged hospital stay and incurred higher healthcare charges than those CP patients without psychiatric disorders.

Internalizing the COVID-19 pandemic: Gendered differences in youth mental health

We review research on gendered patterns of internalizing behaviors in adolescents and emerging adults during the COVID-19 pandemic. We find that young women reported worse mental health than young men. Transgender and gender-diverse (TGD) youth are underrepresented in mental health research but often report the highest internalizing disorders of any gender group. Finally, we use intersectionality as a lens to acknowledge how gender and other social identities (e.g., race, socioeconomic position) impact mental health. Overall, this review points to gender as a meaningful social construct that is relevant for understanding young people's internalizing symptoms during the pandemic. We call attention to the structural factors underlying gender disparities and the need for intersectionality-informed approaches to work towards mental health equity.

Adolescent Mental Health during the COVID-19 Pandemic: The Interplay of Age, Gender, and Mental Health Outcomes in Two Consecutive Cross-Sectional Surveys in Northern Italy

The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on the mental health and well-being of adolescents. This study aimed to investigate the development of health-related quality of life (HRQoL) and mental health among adolescents in Northern Italy by comparing cross-sectional surveys conducted in 2021 and 2022, with a particular focus on the influence of age and gender. The sample included adolescents aged 11-19 years from public schools in South Tyrol. Validated psychometric instruments were used to assess HRQoL, anxiety and depression symptoms, and psychosomatic complaints. Sociodemographic variables, COVID-19 burden, and pandemic-related factors were measured. Statistical analyses included chi-square tests, correlation coefficients, and logistic regression analyses. The results indicated that while the self-reported burden of adolescents decreased significantly in 2022 (n = 1885) compared to 2021 (n = 1760), there were no significant differences in symptoms of anxiety, depressive symptoms, low HRQoL, and increased psychosomatic complaints between the two surveys for both early and late adolescents. Females consistently had higher percentages for all outcome variables, and symptoms of anxiety increased with age in females, but not in males. Both genders experienced an increase in depressive symptoms and low HRQoL with age. The co-occurrence of mental health outcomes was observed, suggesting overlapping patterns among anxiety, depression, low HRQoL, and psychosomatic complaints. These findings underscore the intricate relationship between age, gender, and mental health outcomes among adolescents during the pandemic. It is important to recognize that late adolescents may exhibit distinct vulnerabilities and may require tailored support approaches to address their specific mental health challenges, differing from those needed for early adolescents.

Grit, academic engagement in math and science, and well-being outcomes in children during the COVID-19 pandemic: A study in Hong Kong and Macau

There is evidence showing that the triarchic model of grit and its dimensions (i.e., perseverance of effort, consistency of interests, and adaptability to situations) predict engagement and well-being outcomes in high school and undergraduate students during the COVID-19 pandemic outbreak. However, there has been limited research on how this model of grit relates to engagement and optimal psychological outcomes in primary school students. This research investigates the association of grit's dimensions with academic engagement in math and science as well as well-being outcomes (i.e., positive emotions, negative emotions, and flourishing) in primary school students. Participants were primary school students (Mage = 10.42; SDage = 1.26) from Hong Kong (n = 279) and Macau (n = 124). Results showed that perseverance of effort positively predicted cognitive and behavioral engagement in math as well as positive emotions even after controlling for demographic covariates (i.e., age, gender, setting, and year level), conscientiousness, and achievement goal orientations. Adaptability to situations positively predicted cognitive and social engagement in math and flourishing. Consistency of interests negatively predicted both cognitive engagement in science and negative emotions. Indeed, this study indicates that perseverance and adaptability may facilitate children's positive academic and psychological functioning during the COVID-19 pandemic outbreak.

Maternal Chronic Ultrasound Stress Provokes Immune Activation and Behavioral Deficits in the Offspring: A Mouse Model of Neurodevelopmental Pathology

Neurodevelopmental disorders stemming from maternal immune activation can significantly affect a child's life. A major limitation in pre-clinical studies is the scarcity of valid animal models that accurately mimic these challenges. Among the available models, administration of lipopolysaccharide (LPS) to pregnant females is a widely used paradigm. Previous studies have reported that a model of 'emotional stress', involving chronic exposure of rodents to ultrasonic frequencies, induces neuroinflammation, aberrant neuroplasticity, and behavioral deficits. In this study, we explored whether this model is a suitable paradigm for maternal stress and promotes neurodevelopmental abnormalities in the offspring of stressed females. Pregnant dams were exposed to ultrasound stress for 21 days. A separate group was injected with LPS on embryonic days E11.5 and E12.5 to mimic prenatal infection. The behavior of the dams and their female offspring was assessed using the sucrose test, open field test, and elevated plus maze. Additionally, the three-chamber sociability test and Barnes maze were used in the offspring groups. ELISA and qPCR were used to examine pro-inflammatory changes in the blood and hippocampus of adult females. Ultrasound-exposed adult females developed a depressive-like syndrome, hippocampal overexpression of GSK-3β, IL-1β, and IL-6 and increased serum concentrations of IL-1β, IL-6, IL-17, RANTES, and TNFα. The female offspring also displayed depressive-like behavior, as well as cognitive deficits. These abnormalities were comparable to the behavioral changes induced by LPS. The ultrasound stress model can be a promising animal paradigm of neurodevelopmental pathology associated with prenatal 'emotional stress'.

Behavioral and Sleep Disorders in Children and Adolescents following COVID-19 Disease: A Case-Control Study

INTRODUCTION

Recent studies show that neuropsychiatric disorders are the most frequent sequelae of COVID-19 in children.

PURPOSE

Our work aimed to evaluate the impact of SARS-CoV-2 infection on behavior and sleep in children and adolescents.

MATERIALS AND METHODS

We enrolled 107 patients aged 1.5-18 years who contracted COVID-19 between one year and one month prior to data collection, referred to the University of Campania Luigi Vanvitelli in Italy. We asked their parents to complete two standardized questionnaires for the assessment of behavior (Child Behavior CheckList (CBCL)) and sleep (Sleep Disturbance Scale for Children (SLDS)). We analysed and compared the results with a control group (pre-COVID-19 pandemic).

RESULTS

In the COVID-19 group, the major results were found for sleep breathing disorders, sleep-wake transition disorders and disorders of initiating and maintaining sleep for the SDSC questionnaire, and internalizing scale, total scale and anxiety/depression for the CBCL questionnaire. The comparison of the CBCL results of the cases with the controls revealed statistically significant differences for the following items: internalizing scale, externalizing scale, somatic complaints, total score, thought problems [(p < 0.01)], anxious/depressed problems and withdrawn [(p < 0.001)].

CONCLUSIONS

COVID-19 has impacted children's and adolescents' mental health. Adolescents were the most affected patient group for internalizing problems, including anxiety and depression.

Parents voice their experiences of caring for children with special healthcare needs amid the COVID-19 pandemic

PURPOSE

The purpose of this study was to understand the experiences of parents and caregivers of children with special healthcare needs during the COVID-19 pandemic.

DESIGN AND METHODS

In this descriptive phenomenological study, the researchers used purposive and snowball sampling to recruit nineteen participants, ranging in age from 21 to 55 years of age until saturation was established. Colaizzi's method guided data analysis. Iterative examination of the interview transcripts, an audit trail, bracketing, and validation of findings with a subset of participants established trustworthiness.

RESULTS

Navigating the COVID-19 Pandemic was the overarching theme. Four major themes emerged under Navigating the COVID-19 Pandemic as follows: Disruptions in Daily Life, Shifts in Daily Life, Innovations in Daily Life, and Surprising Silver Linings.

CONCLUSION

This study elucidated an in-depth understanding of the positive and negative impacts of the pandemic on the lives of families living with a child with special needs. The COVID-19 pandemic profoundly affected families and parenting approaches. Parents of children with special healthcare needs in this study found day-to-day living especially difficult in similar and unique ways. For virtually all parents the pandemic added new challenges in meeting their child's physical, mental, social, and educational needs. Parents and caregivers revealed innovative ways of maintaining a sense of normalcy during the height of the pandemic.

PRACTICE IMPLICATIONS

These findings demonstrate the importance of developing interventions and creating public health policies as we move beyond the current pandemic and plan for potential outbreaks in the future.

Psychological Resilience Interventions for Adolescents during the COVID-19 Pandemic

The COVID-19 pandemic has had severe mental health effects on adolescents. Psychological resilience is the ability to recover quickly from adversity and can help adolescents cope with the stress and dangers brought by the pandemic better. Therefore, the current study aimed to explore the developmental pattern of psychological resilience in adolescents and to find the sensitive period for psychological resilience intervention to promote resilience in adolescents during the pandemic. The study measured the psychological resilience of a total of 559 adolescents using the Connor-Davidson resilience scale (CD-RISC) in four grades: grade 7 and grade 8 in a junior high school, and grade 10 and grade 11 in a high school. It was found that the resilience level of the adolescents decreased in grade 10 and then increased significantly in grade 11 (F = 4.22, p = 0.006). A 4-week resilience intervention was conducted in the four grades using both psychological course training and physical training. The results revealed that the psychological course training was effective in promoting resilience in the 7th (F = 4.79, p = 0.03) and 8th (F = 4.75, p = 0.03) grades, but not in the 10th and 11th grades. The result suggests that the 7th and 8th grades may be a critical period for psychological resilience interventions for adolescents.

Mental Health among Italian Children and Adolescents during and after the SARS-CoV-2 Pandemic: A Professionals' Focus Group Study

The SARS-CoV-2 pandemic had a negative impact on the mental health of children and adolescents. Eight focus groups and six individual hearings were conducted to gain insights from the perspectives of 97 Italian professionals from a variety of disciplines, including child and adolescent neuropsychiatrists, pediatricians, general practitioners, social workers, psychologists, teachers, school deans, non-governmental organizations, and a researcher. Urban and rural settings were represented. The present research has been promoted by the Italian Independent Authority for Children and Adolescents (Autorità Garante per l'Infanzia e l'Adolescenza, AGIA) in collaboration with the National Institute of Health (Istituto Superiore di Sanità, ISS) and the Ministry of Education and its scientific value has been supervised by a Scientific Committee. The results of the focus groups' discussions revealed increased vulnerability, with the onset of new mental health disorders in healthy individuals and those in a condition of disadvantage, migratory contexts, and with disabilities. The already critical pre-pandemic structural and operational issues of existing services have been exacerbated. In healthcare, the activation of telemedicine has been a great asset but at the same time has generated challenges and critical issues that are still unresolved. Professionals emphasized the need to pay special attention to planning integrated responses aimed at overcoming inequalities and fragmentation. The result of this initiative translates into a set of operational recommendations useful for guiding investments and policies directed toward the protection of the mental health of minors in the health, educational, and social spheres from the outset.

A Comprehensive Examination of Pediatric Behavioral Health Service Demand and Utilization in a Large, Academic Health System from 2019 to 2021

Studies of the effects of COVID-19 on youth suggest a worsening in mental health globally. We performed a retrospective analysis of data from January 2019-November 2021 for all outpatient referrals, as well as outpatient, inpatient, and emergency department (ED) encounters for behavioral health (BH) reasons in children aged < 18 in a large academic health system in the United States. Mean weekly rates of outpatient psychiatry referrals, outpatient psychiatry visits, ED visits, and inpatient admissions for BH reasons were compared between pre-pandemic and pandemic periods. The average weekly rate of ambulatory referrals (8.0 ± 0.33 to 9.4 ± 0.31) and completed appointments (194.2 ± 0.72 to 213.1 ± 0.71) significantly increased during the pandemic, driven largely by teenagers. The weekly average of ED pediatric encounters for BH did not increase during the pandemic, although the percentage of all pediatric ED encounters that were for BH did increase from 2.6 to 4.1% (p < 0.001). Length of stay for pediatric BH ED patients increased from 1.59 ± 0.09 days pre-pandemic to 1.91 ± 0.11 days post-pandemic (p < 0.0001). Inpatient admissions for BH reasons overall decreased during the pandemic, due to a decrease in inpatient psychiatric bed capacity. However, the weekly percentage of inpatient hospitalizations for BH reasons that occurred on medical units increased during the pandemic (15.2% ± 2.8-24.6% ± 4.1% (p = 0.0006)). Taken together, our data suggest the COVID-19 pandemic had varying degrees of impact, depending on the setting of care.

Evolution of Youth's Mental Health and Quality of Life during the COVID-19 Pandemic in South Tyrol, Italy: Comparison of Two Representative Surveys

BACKGROUND

The coronavirus disease 2019 pandemic has led to an increase in youth mental health problems worldwide. Studies have revealed substantial variation in the incidence of these problems across different regions. Longitudinal studies of children and adolescents in Italy are lacking. This study aimed to investigate the development of health-related quality of life (HRQoL) and mental health in Northern Italy by comparing surveys conducted in June 2021 and in March 2022.

METHODS

A representative, large cross-sectional, online survey investigated HRQoL, psychosomatic complaints, and symptoms of anxiety and depression among 5159 and 6675 children and adolescents in 2021 and 2022, respectively, using the KIDSCREEN-10 index, HBSC symptom checklist, SCARED, CES-DC, and PHQ-2 instruments. Statistical analyses included a multivariate linear regression analysis.

RESULTS

Baseline characteristics showed significant differences in demographic variables between the two surveys. Girls and their parents reported a significantly lower HRQoL in 2021 than in 2022. Psychosomatic complaints differed significantly between sexes, and the results showed no decrease in psychosomatic complaints, anxiety, or depression between 2021 and 2022. Predictors of HRQoL, anxiety, depressive symptoms, and psychosomatic complaints in 2022 differed from those in 2021.

CONCLUSIONS

The characteristics of the 2021 pandemic, including lockdowns and home schooling, may have contributed to the differences between the two surveys. As most pandemic restrictions ended in 2022, the results confirm the need for measures to improve the mental and physical health of children and adolescents after the pandemic.
