Chronic pain in adolescents is associated with suicidal thoughts and behaviors

Adverse Childhood Experiences Moderate the Relationship Between Pain and Later Suicidality Severity Among Youth: A Longitudinal High-Risk Cohort Study

Pain in adolescence can lead to the development of serious mental health issues, including suicidality. This risk may be strengthened among youth exposed to more adverse childhood experiences (ACEs; abuse, neglect, household challenges). This longitudinal study examined the role of ACEs in the relationship between pain and later suicidality onset and severity among a cohort of adolescents at risk for developing mental health problems. Participants were 139 healthy youth (Mage = 13.74 years, standard deviation = 1.56, 64% female) between the ages of 11 to 17 years, recruited based on parental history of depression or anxiety. Youth completed validated measures of internalizing symptoms, ACEs, and pain characteristics at baseline and follow-up diagnostic interviews 9 and/or 18 months later to assess for onset and severity of suicidality. After controlling for demographics, baseline internalizing symptoms, and ACEs, worse pain interference and increased ACEs at baseline predicted increased suicidality severity at follow-up. Moderation analyses revealed that there was a significant interaction between ACEs and pain interference and pain intensity. Increased pain interference (b = 7.65, P < .0001) or intensity (b = 6.96, P = .0003) was only associated with increased suicidality severity at follow-up in youth with high levels of ACEs. This study demonstrates that ACEs strengthen the relationship between pain and later suicidality severity among youth at risk of developing mental health problems. Findings underscore the critical need to adopt a trauma-informed lens to pediatric pain prevention and treatment (eg, screening for ACEs) and for the pain to be on the child's mental health agenda. PERSPECTIVE: This article provides evidence that, while pain is a risk factor for future increased suicidality severity, it is a particularly strong risk factor in youth who experienced increased childhood adversity. These results may help identify youth at greatest risk for suicidality.

Suicidal Ideation and Attempts Among Youth With Physical-Mental Comorbidity in Canada: Proposal for an Epidemiological Study

BACKGROUND

Evidence suggests that having a chronic physical illness (CPI; eg, asthma, diabetes, and epilepsy) is an independent risk factor for suicidality (ie, suicidal ideation or attempts) among youth. Less is known about the mechanisms linking CPI and suicidality. Some evidence suggests that mental illness (eg, depression and anxiety) or neurodevelopmental disorder (eg, attention-deficit/hyperactivity disorder) mediates or moderates the CPI-suicidality association. Missing from the knowledge base is information on the association between having co-occurring CPI and mental illness or neurodevelopmental disorder (MIND) on youth suicidality.

OBJECTIVE

This study uses epidemiological data from the 2019 Canadian Health Survey of Children and Youth (CHSCY) to study the intersection of CPI, MIND, and suicidality in youth. We will estimate prevalence, identify predictors, and investigate psychosocial and service use outcomes for youth with CPI-MIND comorbidity versus other morbidity groups (ie, healthy, CPI only, and MIND only).

METHODS

Conducted by Statistics Canada, the CHSCY collected data from 47,850 children (aged 1-17 years) and their primary caregiving parent. Measures of youth CPI, MIND, family environment, and sociodemographics are available using youth and parent informants. Information on psychiatric services use is available via parent report and linkage to national administrative health data found in the National Ambulatory Care Reporting System and the Discharge Abstract Database, which allow the investigation of hospital-based mental health services (eg, emergency department visits, hospitalizations, and length of stay in hospital). Questions about suicidality were restricted to youths aged 15-17 years (n=6950), which form our analytic sample. Weighted regression-based analyses will account for the complex survey design.

RESULTS

Our study began in November 2023, funded by the American Foundation for Suicide Prevention (SRG-0-008-22). Access to the linked CHSCY microdata file was granted in May 2024. Initial examination of CHSCY data shows that approximately 20% (1390/6950) of youth have CPI, 7% (490/6950) have MIND, 7% (490/6950) seriously considered suicide in the past year, and 3% (210/6950) had attempted suicide anytime during their life.

CONCLUSIONS

Findings will provide estimates of suicidality among youth with CPI-MIND comorbidity, which will inform intervention planning to prevent loss of life in this vulnerable population. Modeling correlates of suicidality will advance understanding of the relative and joint effects of factors at multiple levels-information needed to target prevention efforts and services. Understanding patterns of psychiatric service use is vital to understanding access and barriers to services. This will inform whether use matches need, identifying opportunities to advise policy makers about upstream resources to prevent suicidality. Importantly, findings will provide robust baseline of information on the link between CPI-MIND comorbidity and suicidality in youth, which can be used by future studies to address questions related to the impact of the COVID-19 pandemic and associated countermeasures in this vulnerable population of youth.

Drug Safety and Suicidality Risk of Chronic Pain Medications

Chronic pain is one of the main leading causes of disability in the world at present. A variety in the symptomatology, intensity and duration of this phenomenon has led to an ever-increasing demand of pharmacological treatment and relief. This demand for medication, ranging from well-known groups, such as antidepressants and benzodiazepines, to more novel drugs, was followed by a rise in safety concerns of such treatment options. The validity, frequency, and diversity of such concerns are discussed in this paper, as well as their possible effect on future prescription practices. A specific caution is provided towards the psychological safety and toll of these medications, regarding suicidality and suicidal ideation. Most significantly, this paper highlights the importance of pharmacovigilance and underscores the necessity of surveillance programs when considering chronic pain medication.

Prevalence of suicidal behavior in patients with chronic pain: a systematic review and meta-analysis of observational studies

Objective

Chronic pain is a leading cause of disability, severely impairing an individual's daily activity and quality of life. In addition, this condition may contribute to suicidal thoughts by leading to neuropsychological impairments, a perceived lack of meaning in life, and pain-related catastrophizing. This systematic review aimed to comprehensively investigate the prevalence and associated factors of suicidal behaviors (SBs) including suicidal ideation (SI) and suicide attempt (SA) or its complete, in individuals with chronic pain.

Methods

Five electronic databases were searched up to October 4, 2022. Only observational studies investigating the prevalence of SB in individuals with chronic pain were included. The methodological quality of the included studies was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. A meta-analysis was conducted to quantify the prevalence of SB in the population, and the command "Metaprop" was used in STATA/MP 16. In addition, factors explaining the association between chronic pain and SB identified through regression analysis were investigated.

Results

A total of 19 studies were included in this review (N = 3,312,343). The pooled lifetime prevalence of SI and SA was 28.90% (95% confidence interval, 17.95 to 41.26%) and 10.83% (5.72 to 17.30%), respectively, in a mixed sample comprising various chronic pain conditions. Importantly, the pooled prevalence of past 2-week SI was as high as 25.87% (18.09 to 34.50%). The methodological quality of the included studies was not optimal, and studies using validated SB assessment tools were lacking. Potential protective factors against SB in this population included pain coping and self-efficacy, older age, certain race/ethnicity groups, and marriage.

Conclusion

This systematic review and meta-analysis demonstrated the high prevalence of SB in individuals with chronic pain. Specifically, around 1 in 4 individuals with chronic pain had SI within the last 2 weeks. However, there was considerable heterogeneity in the pooled prevalence of SB in this population.

'A whirlwind of everything': The lived experience of adolescents with co-occurring chronic pain and mental health symptoms

BACKGROUND

Co-occurring chronic pain and mental health issues are prevalent in adolescents, costly to society and can lead to increased risk of complications throughout the lifespan. While research has largely examined paediatric chronic pain and mental health in isolation, little is known about the unique challenges faced by adolescents who experience these co-occurring symptoms. This idiographic study examined the lived experience of adolescents with co-occurring chronic pain and mental health symptoms to identify salient issues for this population.

METHODS

Semi-structured telephone interviews were conducted with seven adolescents (11-19 years) self-reporting diagnoses of both pain and mental health issues for a duration of 3 months or longer. Participants were recruited from UK-based schools, pain clinics and charities. Interview transcripts were analysed using interpretative phenomenological analysis.

RESULTS

Analyses generated two themes 'a whirlwind of everything' and 'putting up fronts', which describe how the experience of co-occurring chronic pain and mental health symptoms typically disrupted adolescents' ability to regulate their physical, psychological and social wellbeing and identity. Adolescents described their symptom experience as like an internal storm over which they had no control. Such experiences required adolescents to embrace a variety of symptom management strategies, with adolescents reporting deliberate efforts to minimize their symptoms to external individuals.

CONCLUSION

Co-occurring pain and mental health symptoms may be experienced in similar ways to individually experienced pain or mental health symptoms, but together, the experience may be both more difficult to manage and more socially isolating.

SIGNIFICANCE

Adolescents with co-occurring chronic pain and mental health symptoms describe the experience as if there was a storm inside of them disrupting their sense of physical, emotional and social wellbeing. This inner chaos interferes with their self-identity and relationships with others. Challenges articulating their experiences, and negative encounters associated with their symptoms, further impact feelings of isolation and difficulties accessing support.

Physical activity and education about physical activity for chronic musculoskeletal pain in children and adolescents

BACKGROUND

Chronic pain is a major health and socioeconomic burden, which is prevalent in children and adolescents. Among the most widely used interventions in children and adolescents are physical activity (including exercises) and education about physical activity.

OBJECTIVES

To evaluate the effectiveness of physical activity, education about physical activity, or both, compared with usual care (including waiting-list, and minimal interventions, such as advice, relaxation classes, or social group meetings) or active medical care in children and adolescents with chronic musculoskeletal pain.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, PEDro, and LILACS from the date of their inception to October 2022. We also searched the reference lists of eligible papers, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared physical activity or education about physical activity, or both, with usual care (including waiting-list and minimal interventions) or active medical care, in children and adolescents with chronic musculoskeletal pain.

DATA COLLECTION AND ANALYSIS

Two review authors independently determined the eligibility of the included studies. Our primary outcomes were pain intensity, disability, and adverse events. Our secondary outcomes were depression, anxiety, fear avoidance, quality of life, physical activity level, and caregiver distress. We extracted data at postintervention assessment, and long-term follow-up. Two review authors independently assessed risk of bias for each study, using the RoB 1. We assessed the overall certainty of the evidence using the GRADE approach. We reported continuous outcomes as mean differences, and determined clinically important differences from the literature, or 10% of the scale.

MAIN RESULTS

We included four studies (243 participants with juvenile idiopathic arthritis). We judged all included studies to be at unclear risk of selection bias, performance bias, and detection bias, and at high risk of attrition bias. We downgraded the certainty of the evidence for each outcome to very low due to serious or very serious study limitations, inconsistency, and imprecision. Physical activity compared with usual care Physical activity may slightly reduce pain intensity (0 to 100 scale; 0 = no pain) compared with usual care at postintervention (standardised mean difference (SMD) -0.45, 95% confidence interval (CI) -0.82 to -0.08; 2 studies, 118 participants; recalculated as a mean difference (MD) -12.19, 95% CI -21.99 to -2.38; I² = 0%; very low-certainty evidence). Physical activity may slightly improve disability (0 to 3 scale; 0 = no disability) compared with usual care at postintervention assessment (MD -0.37, 95% CI -0.56 to -0.19; I² = 0%; 3 studies, 170 participants; very low-certainty evidence). We found no clear evidence of a difference in quality of life (QoL; 0 to 100 scale; lower scores = better QoL) between physical activity and usual care at postintervention assessment (SMD -0.46, 95% CI -1.27 to 0.35; 4 studies, 201 participants; very low-certainty evidence; recalculated as MD -6.30, 95% CI -18.23 to 5.64; I² = 91%). None of the included studies measured adverse events, depression, or anxiety for this comparison. Physical activity compared with active medical care We found no studies that could be analysed in this comparison. Education about physical activity compared with usual care or active medical care We found no studies that could be analysed in this comparison. Physical activity and education about physical activity compared with usual care or active medical care We found no studies that could be analysed in this comparison.

AUTHORS' CONCLUSIONS

We are unable to confidently state whether interventions based on physical activity and education about physical activity are more effective than usual care for children and adolescents with chronic musculoskeletal pain. We found very low-certainty evidence that physical activity may reduce pain intensity and improve disability postintervention compared with usual care, for children and adolescents with juvenile idiopathic arthritis. We did not find any studies reporting educational interventions; it remains unknown how these interventions influence the outcomes in children and adolescents with chronic musculoskeletal pain. Treatment decisions should consider the current best evidence, the professional's experience, and the young person's preferences. Further randomised controlled trials in other common chronic musculoskeletal pain conditions, with high methodological quality, large sample size, and long-term follow-up are urgently needed.

Pain and insomnia as risk factors for first lifetime onsets of anxiety, depression, and suicidality in adolescence

ABSTRACT

Chronic pain and mental health problems have both been identified as public health emergencies and co-occur at high rates. This prospective, longitudinal investigation examined whether chronic pain status, pain-related symptoms (intensity, interference), pain catastrophizing, and insomnia severity predicted first lifetime onset of depressive and/or anxiety disorders as well as suicidality in a cohort of youth with a parental history of mood and/or anxiety disorders. Participants included 145 youth (Mage = 13.74 years; 64% female) who completed structured diagnostic interviews at baseline and at 9- and 18-month follow-up to assess depressive and anxiety disorders as well as suicidality. Participants completed baseline questionnaires assessing depressive and anxiety symptoms, pain symptoms and characteristics, pain interference, pain catastrophizing, and insomnia severity. Approximately 25% of youth reported having chronic pain at baseline. Nearly half (47.3%) developed a depressive disorder (21.3%), anxiety disorder (15.7%), or both (10.3%), and 34% endorsed experiencing suicidality at follow-up. Increased pain interference, intensity, catastrophizing, and insomnia severity predicted increased likelihood of first lifetime onset of a depressive disorder at follow-up, over and above sex and baseline symptoms. Chronic pain at baseline was associated with the increased likelihood of onset of suicidality at follow-up. Increased pain intensity and interference at baseline predicted increased severity of suicidality at follow-up. Insomnia severity predicted increased likelihood of anxiety disorder onset. The presence of chronic pain and elevated pain-related symptoms and insomnia are premorbid risk factors for the development of significant mental health disorders and issues in youth.

Identifying and Managing Suicidality in Children and Adolescents with Chronic Pain: Evidence-Based Treatment Strategies

Children and adolescents with chronic pain are at an increased risk of suicidality. This narrative review article aims to inform clinical practice in the assessment and management of suicidality in youth with chronic pain. The article begins with a survey of the background and prevalence of youth with chronic pain. A review of the current evidence behind the increased risk of suicidality in youth with chronic pain follows. Contextualization of this data with general tenets of child and adolescent suicide risk and risk assessment is provided. Suicidology theory including the interpersonal theory of suicide is overviewed to help clinicians to conceptualize the reviewed data. Guiding parameters for the suicide risk assessment and management planning is presented. Concluding recommendations are made to guide clinical practice in the assessment and management of suicidality in youth with chronic pain.

Does depression moderate the relationship between pain and suicidality in adolescence? A moderated network analysis

BACKGROUND

Whilst growing research suggests that pain is associated with suicidality in adolescence, it remains unclear whether this relationship is moderated by co-morbid depressive symptoms. The present study aimed to investigate whether the pain-suicidality association is moderated by depressive symptoms.

METHODS

We performed secondary analyses on cross-sectional, pre-intervention data from the 'My Resilience in Adolescence' [MYRIAD] trial (ISRCTN ref: 86619085; N=8072, 11-15 years). Using odds ratio tests and (moderated) network analyses, we investigated the relationship between pain and suicidality, after controlling for depression, anxiety, inhibitory control deficits and peer problems. We investigated whether depression moderates this relationship and explored gender differences.

RESULTS

Overall, 20% of adolescents reported suicidality and 22% reported pain, whilst nine percent of adolescents reported both. The experience of pain was associated with a four-fold increased risk of suicidality and vice versa (OR=4.00, 95%-CI=[3.54;4.51]), with no gender differences. This cross-sectional association remained significant after accounting for depression, anxiety, inhibitory control deficits and peer problems (aOR=1.39). Depression did not moderate the pain-suicidality association.

LIMITATIONS

The item-based, cross-sectional assessment of pain and suicidality precludes any conclusions about the direction of the effects and which aspects of suicidality and pain may drive this association.

CONCLUSIONS

Our findings underscore the need to consider pain as an independent risk correlate of suicidality in adolescents. Longitudinal research should examine how this relationship develops during adolescence. Clinically, our findings emphasise the need to assess and address suicidality in adolescents with pain, even in the absence of depressive symptoms.

Prospective Associations of Frequent Pain Symptoms With Suicidal Behavior in Adolescents

Chronic pain and suicidal behavior are prevalent in adolescents. This longitudinal study examined the associations between pain symptoms and suicidal behavior in adolescents. A total of 7,072 adolescents participated in a follow-up study of behavior and health in Shandong, China. A self-administered structured questionnaire was used to assess pain symptoms (headache, stomachache, and other nonspecific pain), insomnia, anxiety/depression, substance use, stressful life events, prior suicidal behavior, and family environment in November-December in 2015. One year later, a follow-up survey was conducted. Mean age of the sample was 14.6 years, and half were female. Of the sample, 44.8% and 8.4% reported having one or more pain symptoms "sometimes" and "often", respectively. A total of 22.4% and 10.6% reported having lifetime suicidal behavior at baseline and subsequent suicidal behavior over the 1-year follow-up, respectively. Frequent pain was significantly associated with increased risk of suicidal behavior at baseline (OR=1.64, 95%CI=1.32-2.03) and during the subsequent year (OR=1.50, 95%CI=1.17-1.93) while adjusting for adolescent individual and family covariates. Among adolescents without a history of prior suicidal behavior, frequent pain was significantly associated with an approximately 70% increased risk of incident suicidal behavior (OR= 1.69, 95%CI=1.14-2.51). In conclusion, frequent pain appears to be predictive of adolescent suicidal behavior one year later. PERSPECTIVE: This article presents the prospective associations of frequent pain symptoms with suicidal behavior in adolescents. Frequent pain was associated with a 50-70% increased risk of suicidal behavior 1 year later. The finding underscores the importance of pain assessment and treatment in comprehensive suicide prevention efforts in adolescents.

Exploring the relationship between pain and self-harm thoughts and behaviours in young people using network analysis

BACKGROUND

Self-harm thoughts and behaviours (SHTBs) are a serious public health concern in young people. Emerging research suggests that pain may be an important correlate of SHTBs in young people. However, it remains unclear whether this association is driven by the shared association with other correlates of SHTBs. This study used network analysis to delineate the relationship between SHTBs, pain and other correlates of SHTBs in a population-based sample of young people.

METHODS

We performed secondary analyses, using data from 7977 young people aged 5-16 years who participated in the British Child and Adolescent Mental Health Survey in 2004. We used χ2 tests and network analysis to examine the complex interplay between SHTBs, pain and other correlates of SHTBs, including psychiatric disorders, childhood trauma, stressful life events, parental distress, family dysfunction, peer problems and inhibitory control deficits.

RESULTS

Pain was associated with a doubled risk of SHTBs, and likewise, SHTBs were associated with a doubled risk of pain. Furthermore, network analysis showed that although pain was significantly associated with all measured correlates of SHTBs, except family dysfunction, pain was most strongly associated with SHTBs, after accounting for these measured correlates.

CONCLUSIONS

To the best of our knowledge, this is the first study to utilise network analysis to provide novel insights into the complex relationship between SHTBs, pain and other known correlates of SHTBs in young people. Results suggest that pain is an independent correlate of SHTBs. Future research should aim to identify underlying mechanisms.

Associations between adolescent sleep deficiency and prescription opioid misuse in adulthood

STUDY OBJECTIVES

The main aim of this study was to estimate the association between sleep deficiency in adolescence and subsequent prescription opioid misuse in adulthood using United States nationally representative longitudinal data.

METHODS

Self-reported data captured in the National Longitudinal Study of Adolescent to Adult Health at baseline (Wave 1; mean age = 16 years) and 12 year follow-up (Wave 4; mean age = 29 years). Participants (n = 12,213) reported on four measures of sleep during adolescence (Wave 1) and on lifetime prescription opioid misuse during adulthood (Wave 4). Associations between adolescent sleep and adult opioid misuse were estimated using multivariate logistic regression analysis controlling for sociodemographics, chronic pain, mental health, childhood adverse events, and a history of substance use.

RESULTS

During adolescence, 59.2% of participants reported sleep deficiency. Prospectively, adolescents reporting not getting enough sleep, chronic unrestful sleep, and insomnia were associated with an increased risk for prescription opioid misuse (adjusted odds ratios [OR] = 1.2, p < 0.005 for all three variables). Short sleep duration was not associated with opioid misuse.

CONCLUSION

This is the first study to longitudinally link sleep deficiency as an independent risk factor for the development of prescription opioid misuse. Sleep deficiency could be a driver of the opioid crisis affecting young people in the United States. Future studies should determine whether early and targeted sleep interventions may decrease risk for opioid misuse in high-risk patients prescribed opioids for pain.

Long-term impact of adolescent chronic pain on young adult educational, vocational, and social outcomes

Despite evidence of broad impact on daily functioning in adolescence, little is known regarding the life course effects of childhood chronic pain. This is the first nationally representative study to characterize the disruptive impact of chronic pain in adolescence on key educational, vocational, and social outcomes in young adulthood (12 years later). Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) were used, including 3174 youth with chronic pain and 11,610 without chronic pain. Multivariate regression analyses controlling for sociodemographic factors and adolescent depression found that chronic pain in adolescence was associated with long-term risk of a constellation of impairments indicative of socioeconomic disparities. Specifically, adolescent chronic pain was subsequently associated with reduced educational attainment (eg, lower odds of attaining a high school diploma and bachelor's degree), poor vocational functioning (eg, lower odds of receiving employer-provided benefits and higher odds of receiving public aid), and social impairments (eg, early parenthood, lower self-reported romantic relationship quality) in young adulthood. These findings provide a window into the future of adolescents with chronic pain, contributing to the limited knowledge base of the scope of adverse long-term outcomes during the transition to adulthood. However, several questions remain. Increased research attention is needed to understand the life course impact of pediatric chronic pain, including early risk factors and underlying mechanisms that drive adverse outcomes as they unfold across the lifespan.

The Co-occurrence of Pediatric Chronic Pain and Depression: A Narrative Review and Conceptualization of Mutual Maintenance

OBJECTIVES

Internalizing mental health issues co-occur with pediatric chronic pain at high rates and are linked to worse pain and functioning. Although the field has prioritized anxiety and posttraumatic stress disorder, little is known about co-occurring depression and chronic pain in youth, despite its high prevalence. The purpose of this narrative review was to examine the existing literature on the co-occurrence of pediatric chronic pain and depressive disorders and symptoms and propose a conceptual model of mutual maintenance to guide future research.

METHODS

The literature from both fields of pediatric pain and developmental psychology were searched to review the evidence for the co-occurrence of pediatric chronic pain and depression. Conceptual models of co-occurring mental health issues and chronic pain, as well as child depression, were reviewed. From both literatures, we provide evidence for a number of proposed child, parent, and neurobiological factors that may serve to mutually maintain both conditions over time. On the basis of this evidence, we propose a conceptual model of mutual maintenance and highlight several areas for future research in this area.

RESULTS

Evidence was found for the prevalence of depression in pediatric chronic pain as well as the co-occurrence of both conditions. The key mutually maintaining factors identified and proposed included neurobiological, intrapersonal (eg, cognitive biases, sleep disturbances, emotion regulation, and behavioral inactivation), and interpersonal (eg, parent mental health and pain, genes, and parenting) factors.

DISCUSSION

Given the dearth of research on mutual maintenance in this area, this review and conceptual model could drive future research in this area. We argue for the development of tailored treatments for this unique population of youth to improve outcomes.

Pain as a risk factor for suicidal ideation. A population-based longitudinal cohort study

OBJECTIVE

To examine the longitudinal association between pain and suicidal ideation in the general adult population.

METHOD

Data were used from two waves (baseline and three-year follow-up) of the Netherlands Mental Health Survey and Incidence Study-2. Persons without prior 12-month suicidal ideation at baseline were included in this study (N = 5242). Pain severity and interference due to pain in the past month were measured using the 36-item Short Form Health Survey. Suicidal ideation and DSM-IV mental disorders were assessed using the Composite International Diagnostic Interview. Logistic regression analyses were performed.

RESULTS

Moderate to very severe pain (OR 3.39, p < .001) and moderate to very severe interference due to pain (OR 2.35, p .01) were associated with a higher risk for incident suicidal ideation at follow-up after adjustment for baseline sociodemographic variables and mental disorders. No interaction effects were found between pain severity or interference due to pain and mental disorders.

CONCLUSION

Moderate to severe pain and interference due to pain are risk factors for suicidal ideation independently of concomitant mental disorders. We suggest taking assessment and management of suicidal ideation in patients with pain into account both in clinical treatment as well as in suicide prevention action plans.

The relationship between pain and suicidal vulnerability in adolescence: a systematic review

Leading suicide theories and research in adults suggest that pain can exacerbate the suicidal risk of an individual. Although pain and suicidality (including suicidal ideation, behaviour, and death by suicide) both increase in prevalence during adolescence, the relationship between these factors remains unclear. We aimed to systematically review the empirical evidence for such an association in adolescence. We included 25 observational studies published between January 1961 and December 2018, exploring the potential association between pain and suicidality in adolescents aged 10-19 years. Across various samples and manifestations of pain and suicidality, we found that pain approximately doubles the suicidal risk in adolescents, with a few studies suggesting that pain can predict suicidality longitudinally. Although depression was an important factor, it did not fully explain the association between pain and suicidality. Evidence for associations between pain characteristics and suicidality is sparse and inconclusive, and potentially hides developmental differences between adolescents and adults. Identification of psychological mediators and moderators is required to develop interventions tailored to the needs of adolescents experiencing pain. This study is registered with the PROSPERO database, number CRD42018097226.

Neurocognitive and psychological effects of persistent pain in pediatric sickle cell disease

BACKGROUND

Pain is a major complication of sickle cell disease (SCD), spanning vaso-occlusive crises and persistent pain. Although it is known that persistent pain is associated with considerable impairment in youth without SCD, little is known about the functional effects of persistent pain in SCD. The current study aimed to (a) characterize persistent pain in youth with SCD and (b) determine the extent to which youth with SCD and persistent pain differ in disease morbidity, functional impairment, and neurocognitive and psychological functioning.

PROCEDURE

Eighty-nine participants (ages 7-16) and caregivers completed questionnaires (BRIEF [Behavior Rating Inventory of Executive Function], Conners-3 [Conners-third edition], and PedsQL™-SCD Module, where PedsQL is Pediatric Quality of Life Inventory). Participants completed neurocognitive tests WISC-V [Wechsler Intelligence Scale for Children-fifth edition], WJ-III [Woodcock Johnson Tests of Achievement-third edition], and WIAT-III [Wechsler Individual Achievement Test-third edition]). Youth were classified as having persistent pain if they reported daily pain for 7 days. Chi-square and independent sample t-test analyses were used to assess group differences (those with vs without persistent pain).

RESULTS

Patients with persistent pain (n = 18) reported lower health-related quality of life (P = .000). Caregivers were more likely to rate youth with persistent pain as having lower planning/organization abilities (P = .011) and clinically elevated symptoms of defiance/aggression and oppositional defiance (Ps = .00; .01). Patients with persistent pain demonstrated poorer working memory (P = .023) and processing speed (P = .027), and fewer demonstrating reading fluency abilities in the average or above range (P = .026).

CONCLUSIONS

Youth with SCD and persistent pain are at risk for psychosocial and neurocognitive impairments, suggesting that persistent pain may be an important indicator of disease burden. Furthermore, disease management may be enhanced by assessing cognitive and psychosocial functioning and incorporating interdisciplinary treatments addressing impairment associated with persistent pain.

Best-Evidence for the Rehabilitation of Chronic Pain Part 1: Pediatric Pain

Chronic pain is a prevalent and persistent problem in middle childhood and adolescence. The biopsychosocial model of pain, which accounts for the complex interplay of the biological, psychological, social, and environmental factors that contribute to and maintain pain symptoms and related disability has guided our understanding and treatment of pediatric pain. Consequently, many interventions for chronic pain are within the realm of rehabilitation, based on the premise that behavior has a broad and central role in pain management. These treatments are typically delivered by one or more providers in medicine, nursing, psychology, physical therapy, and/or occupational therapy. Current data suggest that multidisciplinary treatment is important, with intensive interdisciplinary pain rehabilitation (IIPT) being effective at reducing disability for patients with high levels of functional disability. The following review describes the current state of the art of rehabilitation approaches to treat persistent pain in children and adolescents. Several emerging areas of interventions are also highlighted to guide future research and clinical practice.

Cognitive, emotional, and behavioral profile in children and adolescents with chronic pain associated with rheumatic diseases: A case-control study

BACKGROUND

The prevalence of chronic pain is about 30% in children and adolescents which suffer from severe emotional distress. The aim of this observational study is to investigate cognitive, emotional and behavioral consequences of benign chronic pain in children and adolescents suffering of reumathologic diseases.

MATERIALS AND METHODS

A total of 49 participants, chronic pain participants (CPPs) and controls (CGPs), affected by rheumatic diseases, were enrolled. Assessment included collection of sociodemographic data, pain characteristics, and administration of Visual Analog Scale (VAS), Depression Inventory for Children and Adolescents (CDI), Conners' Parent Rating Scales-Revised (CPRS-R), Child Behavior Checklist (CBCL), and Screen for Child Anxiety-Related Disorders (SCARED). For the statistical analysis, Student's t-test for independent samples and Pearson's correlation were used. The significance value was set at p less than .05.

RESULTS

A significant difference of mean scores of CBCL items and of CPRS items between the two groups was found. In CPPs, a significant correlation between VAS and mean scores of several CBCL items and between VAS and mean scores of several CPRS items was found.

CONCLUSION

Chronic pain is a real syndrome in which an interdisciplinary treatment should be applied, considering the psychopathological risk, especially in developmental age.

Self-Directed Violence After Medical Emergency Department Visits Among Youth

INTRODUCTION

Identifying medical encounters that precede self-directed violence may allow for important prevention opportunities. This study examined the risk of self-directed violence after visiting the emergency department for a range of physical health conditions among youth.

METHODS

This retrospective cohort study used 2012-2013 statewide emergency department data from six states. Among patients aged 15-29 years, the exposure group included 2,192,322 emergency department visits for 16 selected conditions, coded by whether visits for those conditions were the first, second, or third or later visit for that condition. Emergency department visits for a minor infection served as the reference group (n=149,163). A Cox proportional hazard model was used to assess the risk of a self-directed violence event within 6 months for each condition. Analyses were conducted in 2017.

RESULTS

Overall, 8,489 (0.4%) of all patients visited the emergency department for self-directed violence over a 6-month period. Initial visits for epilepsy or seizures conveyed a markedly elevated hazard ratio for subsequent self-directed violence at 6.0 and 5.7, respectively (p<0.001). Initial visits for other conditions showed moderately elevated risk with hazard ratios primarily <2. Second visits for various pain symptoms, syncope, vomiting, or non-self-directed violence injury also had a 3- to 5-fold increase in hazard ratios for subsequent self-directed violence. Hazard ratios for third or later visit increased to 8.8 for back pain, 6.9 for headache, about 5 for abdominal pain, dental complaints, and non-self-directed violence injury (p<0.001).

CONCLUSIONS

Young people presenting to the emergency department for certain medical conditions are at an increased risk of subsequent self-directed violence. An awareness of these patterns may help guide screening efforts for suicide prevention in clinical settings.

Chronic pain and suicide risk: A comprehensive review

Death by suicide is one of the leading causes of mortality worldwide. Because individuals with chronic pain are at least twice as likely to report suicidal behaviors or to complete suicide, it is of utmost importance to target which risk factors contribute the most to increasing suicidality. This comprehensive review aims to provide an update on research advancements relating to the identification of potential risk factors for suicidality in individuals with chronic pain. Supporting the results of prior reviews, we found robust evidence that chronic pain itself, regardless of type, was an important independent risk factor for suicidality. The only sociodemographic factor found to be associated with suicidality in individuals with chronic pain was being unemployed/disabled. Depressive symptoms, anger problems, harmful habits (e.g. smoking, alcohol misuse, illicit drugs), childhood or adulthood adversities, and family history of depression/suicide were all also identified as general risk factors. Regarding pain-related factors, sleep problems, poorer perceived mental health, concurrent chronic pain conditions, and more frequent episodes of intermittent pain, were all found to be predictors of suicidality. Unexpectedly, pain characteristics (e.g. type, duration, and intensity/severity) and physical status (e.g. pain interference or disability) were not related to suicide risk. We also identified promising new psychosocial factors (e.g. mental defeat, pain catastrophizing, hopelessness, perceived burdensomeness and thwarted belongingness) associated with suicidality outcomes. A large number of these factors are amenable to change through targeted intervention, highlighting the importance of comprehensively assessing chronic pain patients at risk for suicide, while also incorporating a suicide prevention component into chronic pain management programs.

Associations Between Adolescent Chronic Pain and Prescription Opioid Misuse in Adulthood

Prescription opioid misuse is a serious public health concern, yet antecedent factors are poorly described. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 14,784), we examined the longitudinal relationship between a history of adolescent chronic pain and the odds of misusing prescription opioids in adulthood. The primary predictor variable was chronic pain status during adolescence. The primary outcome variables were prescription opioid misuse during early adulthood and adulthood. Multivariate models controlled for known risk factors of opioid misuse, including sociodemographics (sex, race, and ethnicity), adolescent mental health symptoms (anxiety, depression), adolescent self-reported physical health status, adolescent substance use/abuse, childhood trauma, and adult legitimate opioid use. We found that adults with a history of adolescent chronic pain were more likely to misuse opioids than those without history of chronic pain, even after controlling for other known risk factors. Further, we found that among individuals with history of adolescent chronic pain that race (white), other substance use, and exposure to trauma were risk factors for later opioid misuse. Longitudinal associations between adolescent chronic pain and subsequent adult prescription opioid misuse highlight the need for early targeted screening and prevention efforts that may reduce later opioid misuse. Perspective: Using a large, nationally representative sample, we found that chronic pain during adolescence was an independent risk factor for opioid misuse in adulthood, over and above other known risk factors. Furthermore, among those individuals with adolescent chronic pain, substance use, exposure to trauma, and race were associated with opioid misuse.

Suicide Attempts Among Adolescents with Self-Reported Disabilities

This study examines the relative risk for suicide attempts (SA) among high-school students self-identifying with one or more disability classifications (nine); assesses the extent to which youth with disabilities are disproportionately vulnerable to risk factors that predict suicidal behavior among all adolescents; and explores whether disability status adds to risk for SA after accounting for a comprehensive set of known risk and protective factors for SA. Analyses using Wisconsin's 2012 Dane County Youth Assessment Survey data found that youth in each disability category were 3-9 times more likely to report suicide attempt(s) relative to peers, and the endorsement of multiple disabilities tripled the risk SA relative to youth reporting a single disability. Some disability sub-groups, including youth reporting autism spectrum disorder, hearing, and vision impairments reported surprisingly high rates of SA. While youth with disabilities reported disproportionate exposure to adversity in every life domain examined, similar to youth reporting SA, disability status added unique risk for suicidal behavior. This suggests that disability may be a 'fundamental cause' of suicidal behavior, a question that requires further investigation.

The association between pain and suicidal behavior in an English national sample: The role of psychopathology

Pain has been linked with an increased risk of engaging in suicidal behavior. However, the role of common mental disorders (CMDs) and borderline personality disorder (BPD) traits in this association is largely unknown. This study was based on data from the 2007 Adult Psychiatric Morbidity Survey (N = 7403). Suicidal behavior referred to past 12-month suicidal ideation and suicide attempt. Pain was assessed in terms of the level of its interference with work activity in the past four weeks. BPD traits were assessed with the structured interview for DSM disorders questionnaire, and CMDs with the Clinical Interview Schedule Revised (CIS-R). Multivariate logistic regression and mediation analyses were conducted to analyze the association between pain and suicidal behavior, and the role of CMDs and BPD traits in this association. The prevalence of past 12-month suicidal ideation and suicide attempt increased from 2.7% to 11.5% and 0.2% to 2.4%, respectively, between no pain and extreme pain. Pain was found to be significantly associated with suicidal ideation (ORs = 1.61-2.92) and suicide attempt (ORs = 2.95-6.70). CMDs were significant mediators in the pain-suicidal behavior relationship but did not fully explain the association. BPD had little influence in this association. Assessing suicide risk in individuals with pain may be important for suicide prevention. Treating CMDs may reduce risk for suicide in these individuals but other factors leading to higher risk for suicidal behavior should also be investigated in future studies.

Metacognition and Headache: Which Is the Role in Childhood and Adolescence?

Headache, in particular migraine, is one of the most frequent neurological symptoms in children and adolescents and it affects about 60% of children and adolescents all over the world. Headache can affect several areas of child’s functioning, such as school, physical activities, peer, and family relationship. The global and severe burden of this disease requires a multidisciplinary strategy and an effective treatment addressed all of the patient’s needs and based on cutting-edge scientific research. In recent years, research has focused on cognitive factors specifically in functions called metacognitive processes. Metacognition can be defined as the knowledge, beliefs, and cognitive processes involved in monitoring, control, and assessment of cognition. Metacognition seems to be closely related to the ability of theory of mind, the ability to infer, and reason about the mental states of other people in order to predict and explain own behavior. Recent studies found a relationship between metacognitive skills and anxiety, depression, motivation, academic performance, human social interactions, and stress symptoms. This relationship is very interesting for headache treatment, because these factors are the most commonly reported triggers in this disorder and there is a high comorbidity with anxiety and depression in children and adolescents with headache. So, headache and these comorbidities, in particular anxiety and depression, may have in common persistent and maladaptive patterns of thinking which are related to maladaptive metacognitive beliefs. Further research should assess metacognitive processes of children and adolescents with headache in order to increase their ability to control their own cognitive processes and consequently monitor factors which may trigger the attacks.

Suicidal Behaviour Among Adolescents and Young Adults with Self-Reported Chronic Illness

OBJECTIVE

The aims of this study were to estimate the: (1) 12-mo prevalence of suicidal thoughts, plans, and attempts in a population sample of adolescents and young adults with and without chronic illness; (2) associations among chronic illness and suicidal thoughts and behaviour (STB); and, (3) moderating roles of mood and substance use disorder on this association.

METHOD

Individuals were aged 15 to 30 y ( n = 5,248) from the Canadian Community Health Survey-Mental Health. Twelve-month STB and psychiatric disorder were measured using the World Health Organization Composite International Diagnostic Interview 3.0. Multinomial logistic regression examined associations between chronic illness and STB, adjusting for relevant sociodemographic and health characteristics. Product term interactions among chronic illness, mood, and substance use disorders were included in the regression models to examine potential moderating effects.

RESULTS

Prevalence of suicidal thoughts, plans, and attempts was higher in individuals with chronic illness ( P < 0.01 for all). After adjustment, chronic illness increased the odds for suicidal thoughts [OR = 1.28 (1.01 to 1.64)], plans [OR = 2.34 (1.22 to 4.39)], and attempts [OR = 4.63 (1.52 to 14.34)]. In the presence v. absence of a mood disorder, the odds for suicidal thoughts were higher among individuals with chronic illness [OR = 1.89 (1.06 to 5.28)].

CONCLUSIONS

Suicidal thoughts and behaviours are common among adolescents and young adults with chronic illness, particularly among those with comorbid mood disorders. Health professionals should routinely ask about STB during assessments of their adolescent and young adult patients.

Chronic pain in adolescence and internalizing mental health disorders: a nationally representative study

Chronic pain in childhood and adolescence has been shown to heighten the risk for depressive and anxiety disorders in specific samples in adulthood; however, little is known about the association between a wider variety of chronic pains and internalizing mental health disorders. Using nationally representative data, the objectives of this study were to establish prevalence rates of internalizing mental health disorders (anxiety and depressive disorders) among cohorts with or without adolescent chronic pain, and to examine whether chronic pain in adolescence is associated with lifetime history of internalizing mental health disorders reported in adulthood. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) was used (N = 14,790). Individuals who had chronic pain in adolescence subsequently reported higher rates of lifetime anxiety disorders (21.1% vs 12.4%) and depressive disorders (24.5% vs 14.1%) in adulthood as compared with individuals without a history of adolescent chronic pain. Multivariate logistic regression confirmed that chronic pain in adolescence was associated with an increased likelihood of lifetime history of anxiety disorders (odds ratio: 1.33; 95% confidence interval: 1.09-1.63, P = 0.005) and depressive disorders (odds ratio: 1.38; confidence interval: 1.16-1.64, P < 0.001) reported in adulthood. Future research is needed to examine neurobiological and psychological mechanisms underlying these comorbidities.

Association Between Lifetime Headache and History of Suicide Attempts in the Elderly

Background

Pain-related conditions have been reported to play a key role among risk factors for suicide. Headache in particular has been repeatedly associated with suicidal thoughts and behaviors. The aims of this study were: 1) to assess the association between lifetime headache (both non-migrainous headache and migraine) and lifetime suicide attempts (SA); 2) to differentiate, within subjects with lifetime SA, patients with and without lifetime headache in terms of socio-demographic and clinical features.

Methods

We studied 1965 subjects from a cohort of community-dwelling persons aged 65 years and over without dementia (the ESPRIT study), divided in two groups: those with (n = 75), and those without a lifetime SA (n = 1890). Logistic regression analyses were used to compare these groups according to lifetime headache status.

Results

After adjusting for gender, living alone, tobacco and alcohol consumption, and depressive, manic/hypomanic and anxiety disorders, lifetime headache frequency was significantly higher in subjects with a lifetime SA compared with controls (OR = 1.92 [1.17–3.15]). Additionally, different factors were identified as being associated with lifetime SA in participants with lifetime headache (female gender, a lower level of high-density lipoprotein cholesterol, insomnia, lifetime major depression) versus participants without headache (glycemia and lifetime major depression).

Conclusions

Lifetime headache was associated with lifetime SA. Subjects who are women and report the co-occurrence of headache and insomnia as well as lifetime major depression require higher attention and a careful screening for suicidal thoughts and behaviors.

Chronic Pain in Children and Adolescents: Diagnosis and Treatment of Primary Pain Disorders in Head, Abdomen, Muscles and Joints

Primary pain disorders (formerly "functional pain syndromes") are common, under-diagnosed and under-treated in children and teenagers. This manuscript reviews key aspects which support understanding the development of pediatric chronic pain, points to the current pediatric chronic pain terminology, addresses effective treatment strategies, and discusses the evidence-based use of pharmacology. Common symptoms of an underlying pain vulnerability present in the three most common chronic pain disorders in pediatrics: primary headaches, centrally mediated abdominal pain syndromes, and/or chronic/recurrent musculoskeletal and joint pain. A significant number of children with repeated acute nociceptive pain episodes develop chronic pain in addition to or as a result of their underlying medical condition "chronic-on-acute pain." We provide description of the structure and process of our interdisciplinary, rehabilitative pain clinic in Minneapolis, Minnesota, USA with accompanying data in the treatment of chronic pain symptoms that persist beyond the expected time of healing. An interdisciplinary approach combining (1) rehabilitation; (2) integrative medicine/active mind-body techniques; (3) psychology; and (4) normalizing daily school attendance, sports, social life and sleep will be presented. As a result of restored function, pain improves and commonly resolves. Opioids are not indicated for primary pain disorders, and other medications, with few exceptions, are usually not first-line therapy.

Increased rates of body dissatisfaction, depressive symptoms, and suicide attempts in Jamaican teens with sickle cell disease

BACKGROUND

This study aims to examine the association of body image and weight perceptions with risk of depression and suicidal attempts in Jamaican adolescents with sickle cell disease (SCD).

METHODS

Adolescents with SCD and a national sample of Jamaican adolescents completed a questionnaire examining body image, weight perceptions, and risk for depression.

RESULTS

Perceived and desired body images were similar for both groups. Adolescents with SCD had higher levels of "negative body satisfaction" (43.9% vs. 33.9%; P = 0.03), risk for depression (28.7% vs. 19.3%; P = 0.01), and attempted suicide (12.4% vs. 6.6%; P = 0.02) than national sample. Risk of depression was higher in those who perceived themselves to be over or underweight, and lower in those with more friends and attending school. Females and those with body image dissatisfaction were more likely to have attempted suicide. Within the SCD adolescents, girls were at greater odds of having mental health issues.

CONCLUSIONS

Jamaican adolescents with SCD have significantly higher rates of negative body satisfaction and depressive symptoms, and nearly twice the rate of attempted suicide, compared with their healthy peers. This underscores the need for healthcare professionals to better explore and discuss healthy weight, body satisfaction, and coping with the demands and uncertainties of having a chronic illness with Jamaican adolescents with SCD, even while promoting body acceptance and good self-esteem. Screening for mood disorders is strongly recommended and gender-specific interventions should be developed. Healthcare professionals need to encourage positive social interactions that improve adolescents' mental health.

Pain-related and Psychological Symptoms in Adolescents With Musculoskeletal and Sleep Problems

Objectives:

Two-thirds of adolescents with chronic musculoskeletal pain report a concurrent sleep problem. Both musculoskeletal pain and sleep problems can have deleterious effects on physiological and psychological well-being. We explored the prevalence of sleep problems and musculoskeletal pain, using data on 3568 adolescents from the Avon Longitudinal Study of Children.

Materials and Methods:

A comprehensive battery of questionnaires was administered to derive clinical phenotypes of musculoskeletal pain. Adolescents with single symptoms were compared with those reporting both musculoskeletal pain and sleep problems. Linear and logistic regression analyses were used to compare groups on pain-related variables and psychological complaints. The association between sociodemographic variables and comorbid musculoskeletal pain and sleep problems was assessed using logistic regression.

Results:

Over half the sample was female (n=2076, 58.2%) and the majority of European ancestry (n=3174, 97.7%). Only 5.5% (n=196) of participants were identified as having a pain condition, while 21.2% (n=749) reported a significant sleep problem, and 2.8% (n=99) reported comorbid musculoskeletal pain and sleep problems. Adolescents with comorbid problems experienced greater pain intensity and pain-related anxiety. Other psychological complaints were also higher in those who experienced concurrent problems, including depression, fatigue, concentration, and overall severity of psychological symptoms.

Discussion:

Comorbid sleep and pain problems were associated with a higher incidence of pain-related and psychological symptoms. Sleep problems may therefore be an important modifiable risk factor for alleviating distress in adolescents with musculoskeletal pain.

Subanesthetic ketamine infusions for the treatment of children and adolescents with chronic pain: a longitudinal study

BACKGROUND

Chronic pain is common in children and adolescents and is often associated with severe functional disability and mood disorders. The pharmacological treatment of chronic pain in children and adolescents can be challenging, ineffective, and is mostly based on expert opinions and consensus. Ketamine, an N-methyl-D-aspartate receptor antagonist, has been used as an adjuvant for treatment of adult chronic pain and has been shown, in some instances, to improve pain and decrease opioid-requirement. We examined the effects of subanesthetic ketamine infusions on pain intensity and opioid use in children and adolescents with chronic pain syndromes treated in an outpatient setting.

METHODS

Longitudinal cohort study of consecutive pediatric patients treated with subanesthetic ketamine infusions in a tertiary outpatient center. Outcome measurements included self-reported pain scores (numeric rating scale) and morphine-equivalent intake.

RESULTS

Over a 15-month period, 63 children and adolescents (median age 15, interquartile range 12-17 years) with chronic pain received 277 ketamine infusions. Intravenous administration of subanesthetic doses of ketamine to children and adolescents on an outpatient basis was safe and not associated with psychotropic effects or hemodynamic perturbations. Overall, ketamine significantly reduced pain intensity (p < 0.001) and yielded greater pain reduction in patients with complex regional pain syndrome (CRPS) than in patients with other chronic pain syndromes (p = 0.029). Ketamine-associated reductions in pain scores were the largest in postural orthostatic tachycardia syndrome (POTS) and trauma patients and the smallest in patients with chronic headache (p = 0.007). In 37% of infusions, patients had a greater than 20 % reduction in pain score. Conversely, ketamine infusions did not change overall morphine-equivalent intake (p = 0.3).

CONCLUSIONS

These data suggest that subanesthetic ketamine infusion is feasible in an outpatient setting and may benefit children and adolescents with chronic pain. Further, patients with CRPS, POTS, and a history of trauma-related chronic pain are more likely to benefit from this therapeutic modality.

The impact of physical pain on suicidal thoughts and behaviors: Meta-analyses

Although the relationship between physical pain and suicidal thoughts and behaviors has been explored in multiple epidemiologic and clinical studies, it is still far from being well understood. Consequently, we conducted a meta-analysis of studies comparing rates of suicidal thoughts and behaviors in individuals with and without physical pain. We searched MEDLINE and PsycINFO (May 2015) for studies comparing rates of current and lifetime suicidal thoughts and behaviors (death wish, suicide ideation, plan, attempt and death: DW, SI, SP, SA, SD) in individuals with any type of physical pain (headache, back, neck, chest, musculoskeletal, abdominal and pelvic pains, arthritis, fibromyalgia, medically unexplained pain, and other not specified pain) versus those without it. Data were analyzed with Cochrane Collaboration Review Manager Software (RevMan, version 5.3). We assessed the methodological quality of the studies with the STROBE statement. Of the 31 included studies, three focused on lifetime DW, twelve focused on current SI (six lifetime), six focused on current SP (two lifetime), nine focused on current SA (11 lifetime) and eight on SD. Individuals with physical pain were more likely to report lifetime DW (p = 0.0005), both current and lifetime SI (both p < 0.00001), SP (current: p = 0.0008; lifetime: p < 0.00001), and SA (current: p < 0.0001; lifetime: p < 0.00001). Moreover, they were more likely to report SD (p = 0.02). In all analyses, the between study heterogeneity was high. Moreover, the presence of publication bias has been detected in the main outcomes. Physical pain is a consistent risk factor for suicidal thoughts and behaviors. Further research is required to investigate the specific impact of: 1) chronic versus acute pain, 2) different types of pain (e.g., medically unexplained pain), and 3) risk factors for suicide in chronic pain patients.

The association of self-injurious behaviour and suicide attempts with recurrent idiopathic pain in adolescents: evidence from a population-based study

BACKGROUND

While several population-based studies report that pain is independently associated with higher rates of self-destructive behaviour (suicidal ideation, suicide attempts, and self-injurious behaviour) in adults, studies in adolescents are rare and limited to specific chronic pain conditions. The aim of this study was to investigate the link between self-reported idiopathic pain and the prevalence and frequency of self-injury (SI) and suicide attempts in adolescents.

METHODS

Data from a cross-sectional, school-based sample was derived to assess SI, suicide attempts, recurrent pain symptoms and various areas of emotional and behavioural problems via a self-report booklet including the Youth Self-Report (YSR). Adolescents were assigned to two groups (presence of pain vs. no pain) for analysis. Data from 5,504 students of 116 schools in a region of South Western Germany was available. A series of unadjusted and adjusted multinomial logistic regression models were performed to address the association of pain, SI, and suicide attempts.

RESULTS

929 (16.88%) respondents reported recurrent pain in one of three areas of pain symptoms assessed (general pain, headache, and abdominal pain). Adolescents who reported pain also reported greater psychopathological distress on all sub-scales of the YSR. The presence of pain was significantly associated with an increased risk ratio (RR) for SI (1-3 incidences in the past year: RR: 2.96; >3 incidences: RR: 6.04) and suicide attempts (one attempt: RR: 3.63; multiple attempts: RR: 5.4) in unadjusted analysis. Similarly, increased RR was observed when adjusting for sociodemographic variables. While controlling for psychopathology attenuated this association, it remained significant (RRs: 1.4-1.8). Sub-sequent sensitivity analysis revealed different RR by location and frequency of pain symptoms.

CONCLUSIONS

Adolescents with recurrent idiopathic pain are more likely to report previous incidents of SI and suicide attempts. This association is likely mediated by the presence of psychopathological distress as consequence of recurrent idiopathic pain. However, the observed variance in dependent variables is only partially explained by emotional and behavioural problems. Clinicians should be aware of these associations and interview adolescents with recurrent symptoms of pain for the presence of self-harm, past suicide attempts and current suicidal thoughts. Future studies addressing the neurobiology underpinnings of an increased likelihood for self-injurious behaviour and suicide attempts in adolescents with recurrent idiopathic pain are necessary.

Psychosocial correlates of suicidal ideation in rural South African adolescents

Suicide is a prevalent problem among young people in Southern Africa, but prevention programs are largely absent. This survey aimed to identify the behavioral and psychosocial correlates of suicidal ideation among adolescents in Limpopo. A two-stage cluster sample design was used to establish a representative sample of 591 adolescents. Bivariate correlations and multiple linear regression analyses were conducted. Findings show that suicidal ideation is prevalent among adolescents. The psychosocial factors perceived social support and negative feelings about the family and the behavioral factors forced sexual intercourse and physical violence by the partner were found to increase the risk of suicidal ideation. Depression mediated the relationship between these psychosocial and behavioral risk factors and suicidal ideation. This study increased our understanding of the psychosocial and behavioral predictors of adolescent suicidal ideation. The findings provide target points for future intervention programs and call for supportive structures to assist adolescents with suicidal ideation.

Adolescent Nonmedical Use of Prescription Pain Relievers, Stimulants, and Depressants, and Suicide Risk

BACKGROUND

Although the link between drug abuse and suicide risk is established, few studies have examined the relationship between the nonmedical use of prescription drugs (NMUPD) and suicide risk, particularly among adolescents.

OBJECTIVES

To explore the relationship between NMUPD and suicide risk among 4,148 adolescents in grades 9-12 enrolled in five public high schools.

METHODS

Logistic regression models were constructed for the nonmedical use of prescription pain relievers, depressants, stimulants, and a composite measure for any NMUPD. Models were estimated before and after controlling for key covariates.

RESULTS

About 21% of respondents reported lifetime NMUPD. After covariate adjustment, students who had reported any NMUPD were between 1.7 and 2.3 times more likely to report suicidal ideation, but not a suicide attempt (p < .0001). When stratified by sex and drug, nonmedical use of pain relievers, stimulants, and depressants were significantly associated with greater odds of suicidal ideation and behavior for both males and females (p < .05). However, NMUPD of pain relievers were not associated with greater odds of suicide attempts for males or females or among males who reported nonmedical use of stimulants. Nonmedical use of depressants was associated with greater odds of suicide attempts for both males and females (OR = 1.61 and 2.25, respectively) and among females who reported nonmedical use of stimulants (OR = 2.06, p < .01).

CONCLUSIONS/IMPORTANCE

Results suggest that some adolescents may be inappropriately self-medicating psychological distress with prescription medications or NMUPD may promote suicide risk, especially for males and females who use depressants and females who use stimulants.

Factors Associated with Sexual Orientation and Gender Disparities in Chronic Pain Among U.S. Adolescents and Young Adults

OBJECTIVE

This research investigated factors associated with sexual orientation disparities in chronic pain frequency among youth.

METHOD

Data were analyzed from 4534 female and 3785 male youth from Waves I-IV (1995-2009) of the U.S. National Longitudinal Study of Adolescent to Adult Health. Gender-stratified weighted logistic regression models controlled for sociodemographic characteristics and included sexual orientation (primary predictor) and frequency of three types of chronic pain (outcomes). Models with sexual orientation only were compared to models with factors hypothesized to increase or decrease risk of pain. Significant odds ratios (OR) for chronic pain frequency (daily/weekly vs. rarely) with confidence intervals (CI) and associated factors are reported.

RESULTS

Compared to same-gender heterosexual females, mostly heterosexuals were more likely to report headaches (OR=1.40, CI=1.09, 1.79) and mostly heterosexuals and bisexuals were more likely to report muscle/joint pain (mostly heterosexual OR=1.69, CI=1.29, 2.20; bisexual OR=1.87, CI=1.03, 3.38). Compared to same-gender heterosexual males, gay males were more likely to report headaches (OR=2.00, CI=1.06, 3.82), but less likely to report muscle/joint pain (OR=0.28, CI=0.11, 0.74). Significant disparities were attenuated by up to 16% when associated factors were added to the model.

CONCLUSION

Sexual orientation disparities in chronic pain were partially explained by associated factors, but more research is needed to develop intervention and prevention strategies.

Change in suicidal ideation after interdisciplinary treatment of chronic pain

OBJECTIVES

To examine suicidal ideation (SI) in individuals with chronic pain, especially change in suicidal thinking after interdisciplinary treatment.

MATERIALS AND METHODS

Consecutive patients (n=250) admitted to a 4-week, group-based chronic pain management program completed measures of pain intensity, functional limitations, depressive symptoms, overall distress, pain catastrophizing, self-perceived burden, and SI at pretreatment and posttreatment.

RESULTS

Before treatment, 30 (12.0%) participants were classified as having a high level of SI, 56 (22.4%) had a low level of SI, and 164 (65.6%) reported none. After treatment, there was a significant reduction in SI and improvements in all other outcomes, but there were still some individuals with high (n=22, 8.8%) or low (n=28, 11.2%) levels at discharge. Patients with high SI at baseline differed from those with no suicidal thinking on pretreatment and posttreatment measures of depression, distress, catastrophizing, and self-perceived burden, but not on pain intensity or functional limitations. Patients high in SI endorsed greater pain catastrophizing and self-perceived burden than those low in suicidal thinking. Sustained SI after treatment was associated with higher baseline levels of suicidal thinking and self-perceived burden to others, as well as a more limited overall response to treatment.

DISCUSSION

SI was common in individuals with chronic pain, although mostly at a low level. Interdisciplinary treatment may result in reduced suicidal thinking; however, some patients continue to express thoughts of self-harm. Future studies could examine processes of change and interventions for treatment-resistant suicidal concerns.

The pain suicidality association: a narrative review

OBJECTIVES

The objective of this narrative review was to examine recent evidence and, when necessary, past evidence on the association between pain and suicidality.

DESIGN

Fifty-eight research reports were found on this topic, which had not previously been reviewed. These reports were divided into groups by whether they addressed suicide ideation (SI), suicide attempts (SAs), or suicide completion (SC), and what population they represented (acute pain patients [APPs], chronic pain patients [CPPs], other than APPs/CPPs) and whether they controlled for relevant confounders. Information as to whether the results of these studies supported/did not support the association of pain and suicidality was abstracted. For each group of studies (above), a vote counting method was utilized to determine the overall percentage of studies supporting/not supporting the association of pain and suicidality. According to this percentage, the consistency of the data supporting this association was rated according to Agency for Healthcare Research and Quality guidelines.

RESULTS

The following groups of studies received an A consistency rating (consistent evidence from multiple studies): SI, SA, and SC for other than APPs/CPPs; and SI, SA, and SC for CPP prevalence greater than an appropriate control group. Also, a subgroup of the SI, SA, and SC studies for other than APPs/CPPs had controlled for behavioral issues (potential confounders). These three subgroups also received an A consistency rating. The 58 studies also identified a number of new predictor variables for SI, SA, and SC in CPPs.

CONCLUSIONS

These studies solidify the evidence for an association between pain and SI, SA, and SC in both CPPs and other than APPs/CPPs.

Pain relief as a primary treatment goal: at what point does functioning and well-being become more important? A case study of an adolescent with debilitating chronic pain

BACKGROUND

Pediatric chronic pain is a common problem with significant economic implications and devastating consequences on quality of life. The present report describes a case involving a 15-year-old girl with severe and debilitating chronic pain.

RESULTS

Before her referral to a pain rehabilitation program, the patient saw numerous specialists who treated her with an aggressive medical regimen and two spinal cord stimulators. She was then referred for intensive interdisciplinary treatment and, after three weeks of rehabilitation, she reported clinically significant changes in anxiety, pain catastrophizing and functional disability. The patient was successfully titrated off all of her opioid medications and, eventually, both neurostimulator implants were removed.

DISCUSSION

Interdisciplinary pain rehabilitation is a useful treatment for patients with chronic pain. With its primary emphasis on functional restoration as opposed to strictly pain reduction, patients can regain a higher quality of life with reduced pain and fewer medications, surgeries and hospitalizations.

Presentation and management of chronic pain

Chronic pain is an important clinical problem affecting significant numbers of children and their families. The severity and impact of chronic pain on everyday function is shaped by the complex interaction of biological, psychological and social factors that determine the experience of pain for each individual, rather than a straightforward reflection of the severity of disease or extent of tissue damage. In this article we present the research findings that strongly support a biopsychosocial concept of chronic pain, describe the current best evidence for management strategies and suggest a common general pathway for all types of chronic pain. The principles of management of some of the most important or frequently encountered chronic pain problems in paediatric practice; neuropathic pain, complex regional pain syndrome (CRPS), musculoskeletal pain, abdominal pain and headache are also described.

Do headache and abdominal pain in childhood predict suicides and severe suicide attempts? Finnish nationwide 1981 birth cohort study

This study investigated associations between pain symptoms in mid-childhood and severe suicidality in adolescence and early adulthood. Severe suicidality was defined as completed suicide or suicidal attempt requiring hospital admission. In a nationwide prospective population-based study (n = 6,017), parents and children were asked about the child's headache and abdominal pain at age eight. The outcome was register-based data on suicide or suicidal attempt requiring hospital treatment by age 24. Family composition, parental educational level, and the child's psychiatric symptoms reported by the child, parents and teacher at baseline were included as covariates in statistical analyses. Boys' abdominal pain reported by the parents was associated with later severe suicidality after adjusting for family composition, parental educational level, and childhood psychiatric symptoms at baseline. In addition, the association between boys' own report of headache and later severe suicidality reached borderline significance in unadjusted analysis. Girls' pain symptoms did not predict later severe suicidality.

Psychological processing in chronic pain: a neural systems approach

Our understanding of chronic pain involves complex brain circuits that include sensory, emotional, cognitive and interoceptive processing. The feed-forward interactions between physical (e.g., trauma) and emotional pain and the consequences of altered psychological status on the expression of pain have made the evaluation and treatment of chronic pain a challenge in the clinic. By understanding the neural circuits involved in psychological processes, a mechanistic approach to the implementation of psychology-based treatments may be better understood. In this review we evaluate some of the principle processes that may be altered as a consequence of chronic pain in the context of localized and integrated neural networks. These changes are ongoing, vary in their magnitude, and their hierarchical manifestations, and may be temporally and sequentially altered by treatments, and all contribute to an overall pain phenotype. Furthermore, we link altered psychological processes to specific evidence-based treatments to put forth a model of pain neuroscience psychology.

Current analgesic use predicts low emotional quality of life in youth: a cross-sectional survey among university students in Sikkim, North East India

BACKGROUND & OBJECTIVES

Occurrence of chronic physical pain is increasingly identified among youth, and medically unsupervised analgesic use is a possible risk factor for opioid dependence and other mental diseases in later life. Therefore, the present study was carried out in young student population in Sikkim, India, to explore predictors (including current chronic pain and current analgesic use) of low QoL in youth to identify a subset of population vulnerable to substance use and mental diseases in later life.

METHODS

The study was conducted in a health university setting in Sikkim, North East India. In this cross-sectional study, 156 participants were enrolled with almost equal number of males and females. Generic instruments for demographics and current analgesic use and SF - 36, for assessment of quality of life (QoL), were used. QoL was measured in general, physical and emotional domains. Presence of chronic physical pain during past four weeks was captured using SF - 36.

RESULTS

Almost two-third participants reported presence of current physical pain (69%, n=108); and (14%, n=22) reported current analgesic use for pain. In logistic regression model controlled for age, ethnicity, gender and residence, higher body mass index (BMI) (β=-0.16, P=0.02) and current analgesic use (β=1.6, P=0.006) predicted low QoL in emotional domain (less accomplishment due to emotional problem). Current analgesic use also predicted low QoL in another measure of emotional domain (depressed β=2.0, P=0.001).

INTERPRETATION & CONCLUSIONS

This study identified a subset of participants in their youth with low QoL in emotional domain predicted by current analgesic use and possible overweight problem. Low QoL in more than one emotional domain also identifies possibility of later psychiatric impairment. However, chronic pain did not emerge as a significant predictor of low QoL in emotional domain.

Chronic daily headache in children and adolescents: science and conjecture

SUMMARY Chronic daily headache comprises a group of headache disorders in which headaches occur almost daily or continuously over several months. Although chronic daily headache is one of the most common chronic pain disorders in pediatrics, data on pathophysiological mechanisms and relative efficacy of treatments remain sparse. In this review, we aim to provide contemporary information on classification, epidemiology, etiology and treatment of pediatric chronic daily headache based on extant empirical data when available, or general consensus in the field when not.
