Chronic disruptive pain in emerging adults with and without chronic health conditions and the moderating role of psychiatric disorders: Evidence from a population-based cross-sectional survey in Canada

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.

Validating the 12-item proxy-administered World Health Organization Disability Assessment Schedule (WHODAS) 2.0 in young children with chronic physical illness in Canada

PURPOSE

This study investigated the psychometric properties of the 12-item proxy-administered World Health Organization Disability Assessment Schedule (WHODAS) 2.0 in young children with chronic physical illness in Canada.

MATERIALS AND METHODS

Data come from the Multimorbidity in Youth across the Life-course, a longitudinal study of Canadian youth with physical illnesses (n = 263). Baseline parent-reported data from children (2-9 years, n = 143) and adolescents (10-16 years, n = 117) were analyzed. Wilcoxon's tests examined differences in WHODAS 2.0 scores between subgroups. Internal consistency was estimated, and confirmatory factor analysis modeled the WHODAS 2.0 factor structure. Regression modeling examined if the WHODAS 2.0 could discriminate between children with vs. without mental comorbidity.

RESULTS

Differences were found between children and adolescents regarding self-care and getting along, and for the item on emotional affect. Inter-item correlations were similar between subgroups and internal consistency was strong for children (α = 0.90) and adolescents (α = 0.93). The factor structure of the WHODAS 2.0 was confirmed; parameter estimates were similar between subgroups. The association between mental comorbidity and disability did not differ by age - comorbidity was associated with greater disability (β = 5.87, p < 0.01).

CONCLUSIONS

The 12-item proxy-administered WHODAS 2.0 appears valid and reliable in young children with physical illness and can be used in this population.Implications for rehabilitationThe 12-item proxy-administered WHODAS 2.0 has acceptable inter-item correlations and internal consistency in young Canadian children with chronic physical illness, and its factor structure is consistent with previous reportsExpansion of its use in measuring disability in young children provides the opportunity to use the WHODAS 2.0 across the life-course, facilitating the interpretation of changes in disability over time or in response to treatmentAdditional research is needed to determine responsiveness to change and the minimal clinically important difference of the WHODAS 2.0 in this population.

Prevalence and Correlates of Physical-mental Multimorbidity in Outpatient Children From a Pediatric Hospital in Canada

OBJECTIVE

The aim of this study was to estimate the six-month prevalence of mental illness in children with chronic physical illness (multimorbidity), examine agreement between parent and child reports of multimorbidity, and identify factors associated with child multimorbidity.

METHOD

The sample included 263 children aged 2-16 years with a physician-diagnosed chronic physical illness recruited from the outpatient clinics at a pediatric hospital. Children were categorized by physical illness according to the International Statistical Classification of Diseases and Related Health Problems (ICD)-10. Parent and child-reported six-month mental illness was based on the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID).

RESULTS

Overall, 101 (38%) of children had a parent-reported mental illness; 29 (25%) children self-reported mental illness. There were no differences in prevalence across ICD-10 classifications. Parent-child agreement on the MINI-KID was low (κ = 0.18), ranging from κ = 0.24 for specific phobia to κ = 0.03 for attention-deficit hyperactivity. From logistic regression modeling (odds ratio [OR] and 95% confidence interval), factors associated with multimorbidity were: child age (OR = 1.16 [1.04, 1.31]), male (OR = 3.76 [1.54, 9.22]), ≥$90,000 household income (OR = 2.57 [1.08, 6.22]), parental symptoms of depression (OR = 1.09 [1.03, 1.14]), and child disability (OR = 1.21 [1.13, 1.30]). Similar results were obtained when modeling number of mental illnesses.

CONCLUSIONS

Findings suggest that six-month multimorbidity is common and similar across different physical illnesses. Level of disability is a robust, potentially modifiable correlate of multimorbidity that can be assessed routinely by health professionals in the pediatric setting to initiate early mental health intervention to reduce the incidence of multimorbidity in children.

Correlates of Mental Health in Adolescents and Young Adults with Cerebral Palsy: A Cross-Sectional Analysis of the MyStory Project

Background: It is important to gain a better understanding of mental health issues in adolescents and young adults (AYA) with cerebral palsy (CP). In this cross-sectional study, we explore if demographics, social and clinical questionnaire scores, and cortisol levels in hair samples from AYA with CP are associated with higher scores on anxiety and/or depression questionnaires. Methods: Data from a community-based sample of 63 AYA with CP (30 females; ages 16 to 30 (median age of 25)) were analyzed. Forty-one (65%) participants (20 females) provided a hair sample. Outcomes were assessed using bivariate linear regression analyses and hierarchical regression analyses. Results: Clinical depressive and anxiety symptoms were present in 33% and 31% of participants, respectively. Family functioning, B = 9.62 (95%CI: 5.49–13.74), fatigue, B = 0.15 (95%CI: 0.05–0.25), and pain, B = 1.53 (95%CI: 0.48–2.58) were statistically significant predictors of depressive symptoms. Fatigue, B = 0.24 (95%CI: 0.12–0.35) and pain, B = 1.63 (95%CI: 0.33–2.94) were statistically significant predictors of anxiety. Cortisol levels from hair samples were not found to be associated with depressive symptoms or anxiety. Conclusions: A high prevalence of mental health problems and co-occurring physical problems was found in AYA with CP. Integrating mental support into regular care for AYA with CP is recommended.

Mood and anxiety profiles differentially associate with physical conditions in US adolescents

BACKGROUND

Mood and anxiety are widely associated with physical conditions, but research and treatment are complicated by their overlap, clinical heterogeneity, and manifestation on a spectrum rather than as discrete disorders. In contrast to previous work relying on threshold-level disorders, we examined the association between empirically-derived profiles of mood and anxiety syndromes with physical conditions in a nationally-representative sample of US adolescents.

METHODS

Participants were 2,911 adolescents (aged 13-18) from the National Comorbidity Survey-Adolescent Supplement who provided information on physical conditions and reported at least one lifetime mood-anxiety 'syndrome' based on direct interviews with the Composite International Diagnostic Interview Version 3.0. Mood-anxiety syndromes reflected 3-level ratings from subthreshold to severe distress/impairment, and subtyped mood episodes. Stepwise latent profile analysis identified mood-anxiety profiles and tested associations with physical conditions.

RESULTS

Three mood-anxiety profiles were identified: "Mood-GAD" (25.6%)-non-atypical depression, mania, generalized anxiety; "Atypical-Panic" (11.3%)-atypical depression, panic; and "Reference" (63.1%)-lower mood and anxiety except specific phobia. Headaches were more prevalent in Mood-GAD and Atypical-Panic than Reference (47.9%, 50.1%, and 37.7%, respectively; p=0.011). Heart problems were more common in Mood-GAD than Atypical-Panic (7.4% v 2.2%, p=0.004) and Reference, with back/neck pain more prevalent in Mood-GAD than Reference (22.5% v 15.3%, p=0.016).

LIMITATIONS

Broad categories of physical conditions without information on specific diagnoses; replication regarding specificity is recommended.

CONCLUSIONS

Heart problems and pain-related conditions were differentially associated with specific mood-anxiety profiles. Subtyping depression and anxiety-inclusive of subthreshold syndromes-and their patterns of clustering may facilitate etiologic and intervention work in multimorbidity.

Investigating Specialized Chronic Pain Care Among Emerging Adults

BACKGROUND

  AIMS: To investigate characteristics of emerging adults accessing a specialized chronic non-cancer pain clinic and describe interventions offered and utilized by this group.

DESIGN

A retrospective chart review was conducted of emerging adults and middle-aged adults with chronic pain receiving care over a six-month period.

SETTING

A chronic pain clinic in Southeastern Ontario.

PARTICIPANTS

82 participants comprised of 41 emerging adults (aged 18-29) and 41 middle-aged adults (aged 30-64) METHODS: Groups were matched on sex and number of pain sites. Demographic and pain characteristics, interventions, referrals, and clinic utilization were examined using bivariate and multivariate analysis.

RESULTS

Emerging adults reported lower pain severity scores (t(80) = -2.15, p = .035), were more likely to receive referrals for additional consultation and/or diagnostic investigations (X²(1, n = 82) = 4.97, p = .026) and to have at least one psychology visit (X² = 7.29, p = .007). Moreover, emerging adults with higher depression scores were more likely to see a psychologist (OR 1.23, 95% CI 1.014-1.492).

CONCLUSIONS

Pain presentation and care patterns differed between emerging adults and middle-aged adults. Increased use of non-pharmacologic interventions in emerging adults may reflect differences in pain presentations as well as clinician's sensitivity to emerging adult's particular developmental needs but further research is needed. Further research is needed to contribute to nurses' understanding of the quality and efficacy of pain management approaches.

Physical-mental multimorbidity in children and youth: a scoping review

OBJECTIVE

Efforts to describe the current state of research are needed to advance the field of physical-mental multimorbidity (ie, the co-occurrence of at least one physical illness and at least one mental disorder) among children and youth. Our objective was to systematically explore the breadth of physical-mental multimorbidity research in children and youth and to provide an overview of existing literature topics.

DESIGN

Scoping review.

METHODS

We conducted a systematic search of four key databases: PubMed, EMBASE, PsycINFO and Scopus as well as a thorough scan of relevant grey literature. We included studies of any research design, published in English, referring to physical-mental multimorbidity among children and youth aged ≤18 years. Studies were screened for eligibility and data were extracted, charted and summarised narratively by research focus. Critical appraisal was employed using the modified Quality Index (QI).

RESULTS

We included 431 studies and 2 sources of grey literature. Existing research emphasises the co-occurrence of anxiety, mood and attention disorders among children with epilepsy, asthma and allergy. Evidence consists of mostly small, observational studies that use cross-sectional data. The average QI score across applicable studies was 9.1 (SD=1.8).

CONCLUSIONS

There is a pressing need for more robust research within the field of child physical-mental multimorbidity.

Physical Morbidity and Mental Health Care Among Young People

PURPOSE

This epidemiological study examined associations between morbidity status and mental health care use among young people.

METHODS

Data come from individuals aged 15-29 years (n = 5,630) in the Canadian Community Health Survey-Mental Health (2012). Physical health problems were measured using a standard checklist. The Composite International Diagnostic Interview assessed 12-month mental health and substance use problems. Individuals were asked which types of mental health care they had received in the past year. Logistic, ordinal, and multinomial regression models were computed and the method of variance estimates recovery was used to compare estimates.

RESULTS

Individuals with comorbid physical health problems had higher odds of mental health care use for those with mental (odds ratio [OR] = 12.54 [7.07, 22.25]) and substance use problems (OR = 2.97 [1.75, 5.05]). While these estimates were higher than for individuals without physical comorbidity, differences were not statistically significant. For mental health care needs not being met, associations were found for individuals with mental (OR = 2.56 [1.24, 5.26]) or substance use problems only (OR = 2.48 [1.06, 5.82]).

CONCLUSIONS

Odds of perceiving the need for and using mental health care were high in individuals with a physical comorbidity, but similar to those with mental health or substance use problems only. Young people with a physical comorbidity were less likely to report that their mental health needs are not being met compared to those with mental health or substance use problems only. Research is needed to understand barriers and facilitators faced by young people with mental health or substance use problems as they navigate the health system.

Substance use disorders among youth with chronic physical illness

This study estimated prevalence of substance use disorder in youth with chronic physical illness; quantified magnitudes of association between different chronic physical illnesses with substance use disorder; and, tested whether mental disorder moderates these associations. Data come from 6,377 individuals aged 15-30 years in the Canadian Community Health Survey-Mental Health. Alcohol, cannabis, or other drug use disorder measured using the WHO Composite International Diagnostic Interview 3.0. Individuals with chronic physical illness were more likely to have other drug use disorder compared to healthy controls (2.4% vs. 1.3%; p < .001), but not more likely to have alcohol (7.8% vs. 6.8%) or cannabis use disorder (5.0% vs. 3.6%). Odds of alcohol use disorder were higher among individuals with musculoskeletal conditions, OR = 1.41 (1.03-1.93), but lower among individuals with neurological conditions, OR = 0.49 (0.33-0.72), compared to healthy controls. No associations were found for cannabis use disorder. Odds of other drug use disorder were higher among individuals with endocrine conditions, OR = 2.88 (1.37-6.06). In the presence vs. absence of major depressive disorder, odds for substance use disorder were higher among individuals with respiratory or endocrine conditions. However, odds were lower among individuals with comorbid neurological and major depressive disorders or comorbid respiratory and generalized anxiety disorders. The complexity of the association between chronic physical illness and substance use disorder is compounded when accounting for the moderating effect of mental disorder, which in some contexts, results in a reduced likelihood of substance use disorder in youth with chronic physical illness.

Hair Cortisol Concentration and Mental Disorder in Children With Chronic Physical Illness

Background

To examine changes in hair cortisol concentrations (HCC) in children with chronic physical illness and identify patterns of association between HCC and mental comorbidity.

Methods

A sample of 50 children aged 6 to 16 years were recruited within six months of being diagnosed with a chronic physical illness. Data were collected via hair samples, structured interviews, and behavioral checklists.

Results

There was no change in HCC over six months. Baseline HCC was associated with internalizing—odds ratio (OR) = 1.29 (90% confidence interval (CI): 1.01–1.66)—and externalizing disorders—OR = 1.32 (90% CI: 1.07–1.64). Externalizing disorder at six months was associated with elevated baseline—OR = 1.25 (90% CI: 1.02–1.53)—and six-month HCC—OR = 1.25 (90% CI: 1.02–1.54). Associations between HCC and mental disorder weakened over time, and for internalizing disorders, changed direction (i.e., inverse association), albeit not significantly.

Conclusion

Results provide preliminary evidence that physiological stress, measured using HCC, may be implicated in the relationship between physical and mental illness, and these associations align with attenuated stress responses over time.
