Prevalence of and risk factors for suicidal ideation in adolescents during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND AND OBJECTIVES: Pandemic-related life changes may have had a deleterious impact on suicidal behaviours. Early detection of suicidal ideation and identification of subgroups at increased risk could help prevent suicide, one of the leading causes of death among adolescents worldwide. Here, we aimed to investigate the prevalence of and risk factors for suicidal ideation in adolescents using a population-based sample from Switzerland, two years into the pandemic. METHODS: Between December 2021 and June 2022, adolescents aged 14 to 17 years already enrolled in a population-based cohort study (State of Geneva, Switzerland) were asked about suicidal ideation over the previous year. In addition to a regression model, we conducted a network analysis of exposures which identified direct and indirect risk factors for suicidal ideation (i.e. those connected through intermediate risk factors) using mixed graphical models. RESULTS: Among 492 adolescents, 14.4% (95% CI: 11.5-17.8) declared having experienced suicidal ideation over the previous year. Using network analysis, we found that high psychological distress, low self-esteem, identifying as lesbian, gay or bisexual, suffering from bullying, extensive screen time and a severe COVID-19 pandemic impact were major risk factors for suicidal ideation, with parent-adolescent relationship having the highest centrality strength in the network. CONCLUSION: Our results show that a significant proportion of adolescents experience suicidal ideation, yet these rates are comparable with pre-pandemic results. Providing psychological support is fundamental, with a focus on improving parent-adolescent relationships.

Parental functioning improves the developmental quotient of pediatric liver transplant recipients.

Psychomotor development in pediatric liver transplant (LT) recipients depends on several factors. Our aim was to evaluate the importance of parental involvement and family dynamics on psychomotor development by assessing (i) children and parents individually, (ii) the parent-child relationship, and (iii) the correlation between parental functioning and patient outcome, all before and after LT. Age-appropriate scales were used before and after LT. Twenty-one patients, 19 mothers, and 16 fathers were evaluated. Developmental quotient (DQ): No subjects scored in the "very good" range. The proportion of children with deficits increased from LT to two yr: 17.6% vs. 28.6%. Subjects 0-2 yr were more likely to have normal DQ at transplant (66.7% vs. 50% for older children). Abnormal DQ was more prevalent two yr post-LT in children older at LT (p = 0.02). The mother-child relationship was normal in 59% of families pre-LT and in 67% at two yr. The relationship was more favorable when the child received a transplant as an infant (p = 0.014 at 12 months post-LT). Normal DQ was associated with higher maternal global functioning score pre-LT (p = 0.03). Paternal performance scores were higher than maternal scores. Children transplanted after two yr of age suffer greater long-term deficits than those transplanted as infants.

Impact of the COVID-19 pandemic on children and adolescents: determinants and association with quality of life and mental health-a cross-sectional study.

BACKGROUND: The medium-term impact of the COVID-19 pandemic on the wellbeing of children and adolescents remains unclear. More than 2 years into the pandemic, we aimed to quantify the frequency and determinants of having been severely impacted by the COVID-19 pandemic and estimate its impact on health-related quality of life (HRQoL) and mental health. METHODS: Data was drawn from a population-based cohort of children and adolescents, recruited between December 2021 and June 2022, in Geneva, Switzerland. The Coronavirus impact scale was used to assess the multidimensional impact of the pandemic on children through parent's report. A score higher than one standard deviation above the mean was deemed a severe impact. Parents additionally reported about their offspring HRQoL and mental health with validated scales. Determinants of having been severely impacted were assessed with logistic models, as were the associations between having experienced a severe impact and poor HRQoL or mental health. RESULTS: Out of 2101 participants aged 2-17, 12.7% had experienced a severe pandemic impact. Having a lasting health condition, a pandemic-related worsening of lifestyle habits or an unfavorable family environment were associated with having been severely impacted by the pandemic, while a previous anti-SARS-CoV-2 infection was not. Participants who had experienced a severe pandemic impact were more likely to present poor HRQoL (aOR = 3.1; 95% CI 2.3-4.4) and poor mental health (aOR = 3.9; 95% CI 2.5-6.2). CONCLUSION: The COVID-19 pandemic may have persistent consequences on the wellbeing of children and adolescents, especially among those with health and family vulnerabilities.

Socioeconomic conditions and children's mental health and quality of life during the COVID-19 pandemic: An intersectional analysis.

Background: Children and adolescents are highly vulnerable to the impact of sustained stressors during developmentally sensitive times. We investigated how demographic characteristics intersect with socioeconomic dimensions to shape the social patterning of quality of life and mental health in children and adolescents, two years into the COVID-19 pandemic. Methods: We used data from the prospective SEROCoV-KIDS cohort study of children and adolescents living in Geneva (Switzerland, 2022). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy by nesting participants within 48 social strata defined by intersecting sex, age, immigrant background, parental education and financial hardship in Bayesian multilevel logistic models for poor health-related quality of life (HRQoL, measured with PedsQL) and mental health difficulties (measured with the Strengths and Difficulties Questionnaire). Results: Among participants aged 2-17 years, 240/2096 (11.5%, 95%CI 10.1-12.9) had poor HRQoL and 105/2135 (4.9%, 95%CI 4.0-5.9) had mental health difficulties. The predicted proportion of poor HRQoL ranged from 3.4% for 6-11 years old Swiss girls with highly educated parents and no financial hardship to 34.6% for 12-17 years old non-Swiss girls with highly educated parents and financial hardship. Intersectional strata involving adolescents and financial hardship showed substantially worse HRQoL than their counterparts. Between-stratum variations in the predicted frequency of mental health difficulties were limited (range 4.4%-6.5%). Conclusions: We found considerable differences in adverse outcomes across social strata. Our results suggest that, post-pandemic, interventions to address social inequities in HRQoL should focus on specific intersectional strata involving adolescents and families experiencing financial hardship, while those aiming to improve mental health should target all children and adolescents.

Factor structure of borderline personality disorder symptomatology in adolescents.

OBJECTIVE: To examine the factor structure of the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, criteria for borderline personality disorder (BPD) in a sample of adolescents with a borderline symptomatology. METHOD: The latent structure of borderline criteria, assessed with the Structured Interview for DSM-IV Personality, was explored with a principal factor analysis in a sample of 107 adolescents with a borderline symptomatology drawn from a European research project on BPDs. RESULTS: The principal component analysis revealed 2 homogeneous factors accounting for 66.8% of the variance. The first factor included internally oriented criteria, such as avoidance of abandonment, identity disturbance, chronic feeling of emptiness, and stress-related paranoid ideation. The second factor included externally oriented criteria, such as unstable relationships, impulsivity, suicidal or self-mutilating behaviours, and inappropriate anger. Affective instability was the only criterion loading on both factors. CONCLUSIONS: The results of our study suggests that an internal or external dichotomy may be an appropriate way to conceptualize the structure of borderline criteria in adolescents with a borderline symptomatology, with affective instability being a core feature of BPD at this age.

Determinants of adolescents' Health-Related Quality of Life and psychological distress during the COVID-19 pandemic.

BACKGROUND: We examined the determinants of adolescents' Health-Related Quality of Life (HRQoL) and psychological distress (self-reported and parent-reported) during the COVID-19 pandemic, using a random sample of the population of Geneva, Switzerland. METHODS: Data was drawn from participants aged 14-17 years, who participated with their families to a serosurvey conducted in November and December 2020. Adolescents' HRQoL was evaluated using the validated adolescent-reported KIDSCREEN-10 and parent-reported KINDL® scales. Psychological distress was assessed with self-reported sadness and loneliness, and using the KINDL® emotional well-being scale. Using generalized estimating equations, we examined the role of socio-demographic, family and behavioural characteristics in influencing adolescents' mental health status and wellbeing. RESULTS: Among 240 adolescents, 11% had a low HRQoL, 35% reported sadness and 23% reported loneliness. Based on parents' perception, 12% of the adolescents had a low HRQoL and 16% a low emotional well-being. Being a girl (aOR = 3.20; 95%CI: 1.67-6.16), increased time on social media (aOR = 2.07; 95%CI: 1.08-3.97), parents' average to poor mood (aOR = 2.62; 95%CI: 1.10-6.23) and average to poor household financial situation (aOR = 2.31; IC95%: 1.01-6.10) were associated with an increased risk of sadness. Mismatches between adolescents' and their parents' perception of HRQoL were more likely for girls (aOR = 2.88; 95%CI: 1.54-5.41) and in households with lower family well-being (aOR = 0.91; 95%CI: 0.86-0.96). CONCLUSIONS: A meaningful proportion of adolescents experienced low well-being during the second wave of COVID-19, and average well-being was lower than pre-pandemic estimates. Adolescents living in underprivileged or distressed families seemed particularly affected. Monitoring is necessary to evaluate the long-term effects of the pandemic on adolescents.

A population-based serological study of post-COVID syndrome prevalence and risk factors in children and adolescents.

Post-COVID syndrome remains poorly studied in children and adolescents. Here, we aimed to investigate the prevalence and risk factors of pediatric post-COVID in a population-based sample, stratifying by serological status. Children from the SEROCoV-KIDS cohort study (State of Geneva, Switzerland), aged 6 months to 17 years, were tested for anti-SARS-CoV-2 N antibodies (December 2021-February 2022) and parents filled in a questionnaire on persistent symptoms in their children (lasting over 12 weeks) compatible with post-COVID. Of 1034 children tested, 570 (55.1%) were seropositive. The sex- and age-adjusted prevalence of persistent symptoms among seropositive children was 9.1% (95%CI: 6.7;11.8) and 5.0% (95%CI: 3.0;7.1) among seronegatives, with an adjusted prevalence difference (ΔaPrev) of 4.1% (95%CI: 1.1;7.3). Stratifying per age group, only adolescents displayed a substantial risk of having post-COVID symptoms (ΔaPrev = 8.3%, 95%CI: 3.5;13.5). Identified risk factors for post-COVID syndrome were older age, having a lower socioeconomic status and suffering from chronic health conditions, especially asthma. Our findings show that a significant proportion of seropositive children, particularly adolescents, experienced persistent COVID symptoms. While there is a need for further investigations, growing evidence of pediatric post-COVID urges early screening and primary care management.

Violent behavior of patients admitted in emergency following drug suicidal attempt: a specific staff educational crisis intervention.

OBJECTIVE: In spite of much effort to create guidelines on the management of violent behavior (VB) in emergency departments, little is known about the impact of such guidelines on a real-life emergency environment. The aim of this study is to investigate the impact of a staff educational crisis intervention (SECI) on the reduction of VB in patients admitted to emergency departments following drug suicidal attempt. METHOD: The impact of a SECI on VB of patient consulting the ER following a drug suicide attempt was assessed by comparing the occurrence of VB before (5 months) and after (5 months) the introduction of a SECI. RESULTS: A significant reduction in VB (from 17.32% to 7.14%) was found with the comparison of two 5-month periods: before (254 patients) and after (224 patients) the introduction of a SECI program (chi(2)=11.238; P=.0008). CONCLUSION: These preliminary data suggest the need for further prospective randomized studies aiming to prevent VB in emergency departments by developing specific SECI programs.

Clinical response and risk for reported suicidal ideation and suicide attempts in pediatric antidepressant treatment: a meta-analysis of randomized controlled trials.

CONTEXT: The US Food and Drug Administration (FDA) has issued warnings that use of antidepressant medications poses a small but significantly increased risk of suicidal ideation/suicide attempt for children and adolescents. OBJECTIVE: To assess the efficacy and risk of reported suicidal ideation/suicide attempt of antidepressants for treatment of pediatric major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and non-OCD anxiety disorders. DATA SOURCES AND STUDY SELECTION: PubMed (1988 to July 2006), relevant US and British regulatory agency reports, published abstracts of important scientific meetings (1998-2006), clinical trial registries, and information from authors. Studies were published and unpublished randomized, placebo-controlled, parallel-group trials of second-generation antidepressants (selective serotonin reuptake inhibitors, nefazodone, venlafaxine, and mirtazapine) in participants younger than 19 years with MDD, OCD, or non-OCD anxiety disorders. DATA EXTRACTION: Information was extracted on study characteristics, efficacy outcomes, and spontaneously reported suicidal ideation/suicide attempt. DATA SYNTHESIS: Twenty-seven trials of pediatric MDD (n = 15), OCD (n = 6), and non-OCD anxiety disorders (n = 6) were selected, and risk differences for response and for suicidal ideation/suicide attempt estimated by random-effects methods. Pooled risk differences in rates of primary study-defined measures of responder status significantly favored antidepressants for MDD (11.0%; [95% confidence interval {CI}, 7.1% to 14.9%]), OCD (19.8% [95% CI, 13.0% to 26.6%), and non-OCD anxiety disorders (37.1% [22.5% to 51.7%]), corresponding to a number needed to treat (NNT) of 10 (95% CI, 7 to 15), 6 (4 to 8), and 3 (2 to 5), respectively. While there was increased risk difference of suicidal ideation/suicide attempt across all trials and indications for drug vs placebo (0.7%; 95% CI, 0.1% to 1.3%) (number needed to harm, 143 [95% CI, 77 to 1000]), the pooled risk differences within each indication were not statistically significant: 0.9% (95% CI, -0.1% to 1.9%) for MDD, 0.5% (-1.2% to 2.2%) for OCD, and 0.7% (-0.4% to 1.8%) for non-OCD anxiety disorders. There were no completed suicides. Age-stratified analyses showed that for children younger than 12 years with MDD, only fluoxetine showed benefit over placebo. In MDD trials, efficacy was moderated by age, duration of depression, and number of sites in the treatment trial. CONCLUSIONS: Relative to placebo, antidepressants are efficacious for pediatric MDD, OCD, and non-OCD anxiety disorders, although the effects are strongest in non-OCD anxiety disorders, intermediate in OCD, and more modest in MDD. Benefits of antidepressants appear to be much greater than risks from suicidal ideation/suicide attempt across indications, although comparison of benefit to risk varies as a function of indication, age, chronicity, and study conditions.

Emergent suicidality in a clinical psychotherapy trial for adolescent depression.

OBJECTIVE: The authors' goal was to examine the incidence and predictors of emergent suicidality that occurred during a clinical trial of psychotherapy for adolescent depression. METHOD: The rates and predictors of emergent suicidality in 88 medication-free depressed adolescent outpatients who reported no current suicidality during an intake interview were assessed over 12 to 16 weeks of psychotherapy treatment. RESULTS: The incidence of emergent suicidality was 12.5% (11 of 88 subjects). Self-reported suicidal thoughts at intake were a significant predictor of emergent suicidality, even when suicidality was denied at intake interview. CONCLUSIONS: Emergent suicidality is a common occurrence in psychosocial treatment of adolescent depression, with rates similar to those reported recently in antidepressant trials. To evaluate accurately the role of treatment in emergent suicidality, it is important to assess self-reported suicidality at intake and to balance treatment groups on this key predictor of emergent suicidality.

Clinical differences between suicidal and nonsuicidal depressed children and adolescents.

OBJECTIVE: To examine the clinical symptoms and comorbid psychiatric disorders of depressed children and adolescents with and without clinically significant suicidal ideation. METHOD: Children and adolescents aged 7 to 17 years with current DSM-III-R major depressive disorder (MDD) (N = 135) were recruited between January 1987 and April 2002. Current MDD symptoms and lifetime comorbid psychiatric disorders were assessed using either a combination of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Epidemiologic and -Present Episode versions or the -Present Lifetime version. Thirty-two percent (N = 43) of the depressed subjects were classified as suicidal (at least suicidal ideation with a plan). RESULTS: Depressed suicidal youth presented with a more severe episode (p = .001) and a poorer functional status (p = .019), were more hopeless (p = .001), and presented more frequently with insomnia (p = .011). There was an interaction between suicide x sex x pubertal status for severity of MDD (p = .013), the presence of hopelessness (p < .001), poor functional status (p = .023), and comorbidity with a lifetime history of any disruptive behavior (p = .019). Among pre-pubertal depressed males, suicidal boys had significantly increased severity of MDD (p = .025) and poorer functional status (p = .044) than non-suicidal boys. Among postpubertal depressed females, suicidal girls were more frequently hopeless (p = .008) and presented an increased severity of MDD (p = .022) and more frequent lifetime history of any disruptive behavior (p = .03) when compared with nonsuicidal girls. CONCLUSION: There appears to be a sex difference for some clinical features, particularly hopelessness, among depressed suicidal children and adolescents. Whether hopelessness is a sex-specific characteristic of depressed suicidal children and adolescents requires further study.

Lifetime history of sexual abuse, clinical presentation, and outcome in a clinical trial for adolescent depression.

OBJECTIVE: To investigate the impact of sexual abuse on clinical presentation and treatment outcome in depressed adolescents. METHOD: 107 adolescent outpatients, 13 to 18 years old, with DSM-III-R major depression were randomly assigned to cognitive-behavioral therapy (CBT), systemic behavioral family therapy (SBFT), or nondirective supportive therapy (NST) from Oct. 1, 1991 through May 31, 1995. Subjects were classified on the basis of the presence or absence of lifetime history of sexual abuse. Since only 1 subject assigned to SBFT had a history of sexual abuse, we restricted our analyses to those 72 subjects assigned to either CBT or NST. The impact of lifetime history of sexual abuse on service use, depression, and treatment outcome was examined. RESULTS: Depressed adolescents with a past history of sexual abuse were more likely, at 2-year follow-up, to have had a psychiatric hospitalization and have a depressive relapse, even controlling for maternal depression, source of referral, race, and treatment assignment. CBT was more efficacious than NST in absence of sexual abuse but was not better than NST in those with a history of sexual abuse. CONCLUSION: Sexual abuse is a negative predictor of long-term outcome in adolescent depression. CBT for depression may not be as efficacious for those depressed adolescents with a history of sexual abuse. These findings suggest that a history of sexual abuse should be assessed not only in clinical practice, but also in research studies of depressive outcome. Further work is indicated to understand the relationship between sexual abuse and poor outcome in order to help restore these high-risk youths to an optimal developmental trajectory.

Suicidality and its relationship to treatment outcome in depressed adolescents.

This study investigates the impact of suicidality on treatment outcome in 107 depressed adolescents who participated in a clinical trial, and received either cognitive-behavioral (CBT), systemic-behavioral-family (SBFT), or non-directive-supportive therapy (NST). Suicidal depressed adolescents had a higher dropout rate and were more likely to be depressed at the end of treatment, in large part due to the particularly poor response of suicidal patients to NST. The relationship between suicidality and treatment response was mediated by severity of depression and hopelessness at intake. Hopelessness should be specifically targeted early in treatment. Suicidal depressed adolescents should not receive NST but a specific treatment like CBT.

Screening for bipolar disorder in adolescents with the mood disorder questionnaire-adolescent version (MDQ-A) and the child bipolar questionnaire (CBQ).

AIM: Screening instruments for bipolar disorders (BDs) in children and adolescents have been developed recently. The present study examined performances of the French versions of the mood disorder questionnaire-adolescent version (MDQ-A) and child bipolar questionnaire (CBQ) in a sample of in- and outpatients. METHODS: Seventy-six adolescents (age 13-18) and parents first completed the MDQ-A (adolescent and parent versions) and CBQ screening instruments. About 3 weeks later, they had a diagnostic interview with the Kiddie-schedule for affective disorders and schizophrenia-present and lifetime (K-SADS-PL), and the adolescent MDQ-A self-report was completed a second time. RESULTS: Eight of 76 patients (10.5%) met K-SADS-PL diagnostic criteria for BD. Test-retest reliability of the adolescent MDQ-A self-report was moderate (kappa = 0.66), whereas agreement between adolescent and parent reports was poor (kappa = 0.07). Sensitivity and specificity of the MDQ-A with respect to K-SADS-PL were 75.0% and 57.4% for the adolescent version, and 87.5% and 63.2% for the parent version. Corresponding figures were 50.0% and 73.5% for the CBQ. All three screening instruments had low positive predictive values (17.1% for the MDQ-A adolescent version; 21.9% for the MDQ-A parent version; 18.2% for the CBQ), whereas negative predictive values were higher than 90%. CONCLUSIONS: The present study points to modest performances of the MDQ-A and CBQ to detect BDs in adolescents, with diagnostic criteria for BD being unmet for a majority of patients who screened positive.

Impaired decision making in adolescent suicide attempters.

OBJECTIVE: Decision-making deficits have been linked to suicidal behavior in adults. However, it remains unclear whether impaired decision making plays a role in the etiopathogenesis of youth suicidal behavior. The purpose of this study was to examine decision-making processes in adolescent suicide attempters and never-suicidal comparison subjects. METHOD: Using the Iowa Gambling Task, the authors examined decision making in 40 adolescent suicide attempters, 13 to 18 years old, and 40 never-suicidal, demographically matched psychiatric comparison subjects. RESULTS: Overall, suicide attempters performed significantly worse on the Iowa Gambling Task than comparison subjects. This difference in overall task performance between the groups persisted in an exact conditional logistic regression analysis that controlled for affective disorder, current psychotropic medication use, impulsivity, and hostility (adjusted odds ratio = 0.96, 95% confidence interval = 0.90-0.99, p < 0.05). A two-way repeated-measures analysis of variance revealed a significant group-by-block interaction, demonstrating that attempters failed to learn during the task, picking approximately the same proportion of disadvantageous cards in the first and final blocks of the task. In contrast, comparison subjects picked proportionately fewer cards from the disadvantageous decks as the task progressed. Within the attempter group, overall task performance did not correlate with any characteristic of the index attempt or with the personality dimensions of impulsivity, hostility, and emotional lability. CONCLUSIONS: Similar to findings in adults, impaired decision making is associated with suicidal behavior in adolescents. Longitudinal studies are needed to elucidate the temporal relationship between decision-making processes and suicidal behavior and to help frame potential targets for early identification and preventive interventions to reduce youth suicide and suicidal behavior.

ABCB1 polymorphisms and neuropsychiatric adverse events in oseltamivir-treated children during influenza H1N1/09 pandemia.

AIMS: To examine the safety profile of oseltamivir in children and evaluate the impact of P-glycoprotein polymorphisms on the incidence of neuropsychiatric adverse events (NPAE) in oseltamivir-treated children. SUBJECTS & METHODS: This prospective cohort study was conducted in our tertiary care pediatric hospital (University Hospitals of Geneva, Switzerland) during the H1N1 pandemia, between 1 October 2009 and 31 January 2010. All newborn to 18 year-old patients presenting at the emergency department with a flu-like illness were eligible for inclusion. Adverse events were systematically recorded by pediatricians and/or by parents at home using a diary card, with a 30-day follow-up period. The causality assessment of oseltamivir in NPAE was performed by two clinical pharmacologists. After informed consent, enrolled patients were also genotyped for ABCB1 3435C>T (rs1045642) and 2677G>T/A (rs2032582) polymorphisms. RESULTS: Among the 42 H1N1-infected, oseltamivir-treated children who were genotyped for ABCB1 3435C>T and 2677G>T/A variants, 36% presented NPAE. When examining the association between the diplotype and the development of NPAE, we observed that the frequency of NPAE displayed a 'genotype-trend effect' with the variant and the wild-type subgroups at the two far ends. A total of 11% of the 2677GG-3435CC individuals (wild-type homozygous) presented NPAE, compared with 39% of the individuals being heterozygous for at least one variant allele and 67% of the 2677TT-3435TT individuals (homozygous variants) (p = 0.149, nonsignificant). CONCLUSION: These observations suggest a potential influence of ABCB1 polymorphisms in oseltamivir-related NPAE, maybe as a result of an enhanced permeability of the blood-brain barrier to oseltamivir
