Childhood asthma, chronic illness, and psychiatric disorders

Approach to difficult-to-treat asthma in childhood: a narrative review

ABSTRACT

Asthma is a major chronic disease affecting children, and children with difficult-to-treat asthma account for a disproportionate share of resource utilisation and healthcare costs. This review presents a comprehensive and up-to-date overview of the treatment strategies in difficult-to-treat paediatric asthma. Mimickers of asthma must first be ruled out, and the diagnosis confirmed with objective tests whenever possible. The effect of comorbid conditions such as obesity, smoking, other atopic conditions and psychosocial factors on asthma control and severity should be considered. Treatment can then be optimised by implementing personalised strategies, including the use of appropriate drug delivery devices and adherence monitoring. Biologics can be an alternative treatment option for selected patients but should not be a substitute for addressing poor adherence. Many patients with difficult-to-treat asthma may not have severe asthma, and the physician should work with patients and families to achieve good asthma control via an individualised approach.

Obesity and overweight among children and adolescents with bipolar disorder from the general population: A review of the scientific literature and a meta-analysis

There is substantial evidence of the high prevalence of obesity (OB) and overweight (OW) and their association with increased medical and psychiatric burden among adults with bipolar disorder (BD). However, little is known regarding its prevalence among young people with BD, other than the risk from psychotropic medication, which has been the focus of research in this population. We present a systematic review and meta-analysis of the literature on prevalence and correlates of OB and OW children and adolescents with BD using a different perspective than impact of medication. Four studies met inclusion criteria. The prevalence of OB in children and adolescents with BD was 15% (95% CI 11-20%). We observed a higher prevalence of OB in comparison to the general population. Different studies found significant associations between OB, OW, and BD in young populations including non-Caucasian race, physical abuse, suicide attempts, self-injurious behaviours, psychotropic medication, and psychiatric hospitalizations.

Association between Psychiatric Disorders and Glomerular Disease

Introduction

Patients with chronic health conditions, particularly chronic kidney disease, are at heightened risk for psychiatric disorders; yet, there are limited data on those with primary glomerular disease.

Methods

This study included patients with glomerular disease enrolled in the kidney research network multisite patient registry. Registry data include encounter, diagnoses, medication, laboratory, and vital signs data extracted from participants' electronic health records. ICD-9/10 diagnosis codes were used to identify a subset of psychiatric disorders focused on anxiety, mood, and behavioral disorders. Time-varying Cox proportional hazard models were used to analyze time from the onset of kidney disease to diagnosis of psychiatric disorder. Adjusted models retained significant covariates from the full list of potential confounders, including age, sex, race, ethnicity, time-varying treatment, the estimated glomerular filtration rate, and proteinuria (urine protein-to-creatinine ratio [UPCR]). Analogous models examined diagnosis of psychiatric disorder as a predictor of time to end-stage kidney disease (ESKD).

Results

Data were available for 950 participants, with a median of 58 months of follow-up. 110 (12%) participants were diagnosed with psychiatric disorder during the follow-up. The estimated rate of psychiatric diagnosis after kidney disease was 14.7 cases per 1,000 person-years and was highest among those of adolescent age at the time of kidney disease diagnosis. Adjusted analyses found adolescent age (vs. adult, hazard ratio [HR] = 3.11, 95% confidence interval [CI] 1.87-5.17) and Asian race (vs. white, HR = 0.34, 95% CI 0.16-0.71) were associated with psychiatric diagnosis. A higher UPCR per 1 log unit (HR 1.13, 95% CI 1.01-1.27) and a higher total number of oral medications were associated with psychiatric disorder (p < 0.001). Psychiatric diagnosis was also associated with progression to ESKD (HR = 2.45, 95% CI 1.53-3.92) in adjusted models.

Discussion/Conclusion

Psychiatric disorders were documented in approximately one-eighth of patients with glomerular disease and correlated with clinical disease characteristics such as age, race, proteinuria, and oral medication burden. These findings suggest mental health screening is warranted in patients of all ages with glomerular disease.

Psychological burden of asthma in adolescents and their parents

INTRODUCTION

Asthma, a common chronic disease in adolescents is impacted by factors affecting quality of life. This study aimed to determine the psychosocial factors of adolescents with asthma and their parents.

METHODS

The study included 122 adolescents with asthma, 82 healthy controls, and their parents who completed the Asthma Control Test (ACT), Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and the Brief Symptom Inventory (BSI).

RESULTS

The mean age was 14.2 ± 1.9 years. ACT score was high and depression was low in patients with good treatment compliance. As the age of the first asthma symptoms/diagnosis increased, somatization, anxiety, hostility and general psychopathology scores increased, as did the somatization score of parents. Parental anxiety score was not related with adolescent BSI scores in the controls but in the study group when it was higher, the anxiety, depression, somatization, and general psychopathology scores were higher. PAQLQ showed that anxiety, negative self-esteem, somatization, depression, and general psychopathology were higher in patients concerned about asthma. Depression and somatization scores were higher in the parents of patients who perceived that "Treatment does not contribute to asthma control." Somatization scores were higher among parents of patients who noted: "Asthma will not pass in the long-term" and "I cannot control asthma."

CONCLUSION

Higher scores of asthma patients who were anxious about the disease and families who were despondent about treatment demonstrate that health care providers should spend more time informing patients and caregivers. Increasing patient treatment compliance during early adolescence will lessen the psychological burden of the disease.

Anxiety in asthma: a systematic review and meta-analysis

BACKGROUND

Background: Growing evidence from observational studies indicates a high prevalence of anxiety in asthma. However, prevalence rates of coexisting anxiety symptoms and comorbid anxiety disorders vary widely across studies. We aimed to evaluate the associations between anxiety and asthma and provide more precise comorbidity estimates.

METHODS

We systematically reviewed the literature from case-controlled studies and conducted a meta-analysis to evaluate the pooled prevalence estimates and risks of anxiety symptoms and anxiety disorders in asthma individuals. Screening, data extraction, and quality assessment were undertaken following PRISMA guidelines for preferred reporting of systematic reviews and meta-analysis. A random-effects model was used to calculate pooled prevalence rates. Meta-analysis was conducted using Review Manager 5.3. Multiple databases including PubMed, ScienceDirect, PsychINFO, and PsycARTICLES were searched for publications before 1 December 2019. The review protocol was registered on PROSPERO (ref: CRD42020176028).

RESULTS

In total, 19 studies involving 106813 participants were included. The pooled prevalence of anxiety symptoms and anxiety disorders in individuals with asthma was 0.32 (95% CI 0.22-0.43) and 0.24 (95% CI 0.13-0.41), respectively. The risks of coexisting anxiety symptoms and comorbid anxiety disorders were significantly higher in asthma patients than in non-asthma controls indicated by OR 1.89 (95% CI 1.42-2.52; Z = 4.37; p < 0.001) and OR 2.08 (95% CI 1.70-2.56; Z = 6.97; p < 0.001), respectively. Anxiety symptoms and anxiety disorders occur at increased frequency among patients with asthma.

CONCLUSIONS

Our findings highlight the need for appropriate assessments for these comorbid conditions, which may help to identify a subgroup of patients who might benefit from interventions designed to reduce anxiety and enhance the quality of life.

Inhaled corticosteroids as treatment for adolescent asthma: effects on adult anxiety-related outcomes in a murine model

RATIONALE

Allergic asthma, typically controlled with inhaled corticosteroids (ICS), is the leading chronic health condition for youth under 18 years of age. During this peri-adolescent period, significant brain maturation occurs. Prior studies indicate that both chronic inflammation and corticosteroid medications increase risk for developing an internalizing disorder like anxiety.

OBJECTIVES

To determine if chronic ICS treatments exacerbate or alleviate anxiety symptoms associated with developmental allergic asthma, we used a mouse model to isolate the influence of ICS (fluticasone propionate, FLU) vs. airway inflammation (induced with house dust mite extract, HDM).

METHODS

During development, male and female BALB/cJ mice were repeatedly exposed to HDM or saline plus one of four FLU doses (none/vehicle, low, moderate, or high). In adulthood, we assessed lung inflammation, circulating and excreted corticosteroids, anxiety-like behavior, and gene expression in stress and emotion regulation brain regions.

RESULTS

FLU treatment decreased body weight and anxiety-like behavior and increased fecal corticosterone metabolite concentrations and Crhr2 gene expression in ventral hippocampus. FLU effects were only observed in saline/non-HDM-exposed mice, and the FLU doses used did not significantly decrease HDM-induced airway inflammation. Females had greater serum and fecal corticosterone concentrations, less anxiety-like behavior, and lower Crhr1 gene expression in ventral hippocampus and prefrontal cortex than males.

CONCLUSIONS

These findings suggest that steroid medications for youth with allergic asthma may not exacerbate anxiety-related symptoms, and that they should be avoided in children/adolescents without a health condition. The results are informative to future work on the use of corticosteroid medications during childhood or adolescent development.

Peri-adolescent asthma: Acute impacts on innate immune response, corticosterone, and microglia in mice

Asthma is highly comorbid with anxiety in youth. We investigated the hypothalamic-pituitary-adrenal (HPA) axis and microglia as mechanisms underlying asthma and anxiety comorbidity. We induced asthma symptoms in developing BALB/cJ mice with house dust mite (HDM) for airway inflammation and methacholine (MCH) for bronchoconstriction. On the last day of exposure, we analyzed samples at six timepoints. Lung IL-5 and IL-1β expression peaked 4 h after final HDM exposure. Circulating corticosterone was blunted in a sex- and treatment-specific temporal pattern. Hippocampal IL-1β expression and microglial area were marginally increased 24 h after MCH exposure. These results provide a foundation for further work investigating asthma-anxiety mechanisms.

Systematic Review: Anxiety in Children and Adolescents With Chronic Medical Conditions

OBJECTIVE

Youth with chronic medical conditions (CMCs) have been reported to be at increased risk for developing anxiety disorders. Importantly, suffering from anxiety may also have an impact on their disease-related outcomes. This study set out to systematically review the literature on anxiety and seven CMCs (asthma, congenital heart disease, diabetes, epilepsy, inflammatory bowel disease, juvenile idiopathic arthritis, and sickle cell disease) among youth.

METHOD

A systematic review was performed according to the PRISMA statement. Searches were conducted across PubMed, PsycNET, Embase, and reference lists of the included studies (1990-2018). Three independent reviewers screened titles and abstracts and conducted full-text assessment. Studies were included if they reported the prevalence of anxiety or the association of anxiety on disease-related outcomes in children and/or adolescents with the focal CMCs.

RESULTS

A total of 53 studies met the predetermined inclusion criteria. Across the CMCs, the prevalence of anxiety disorder was increased in youths with CMCs compared to the general population. Evidence for a relationship between anxiety and adverse disease-related outcomes was limited. For asthma, inflammatory bowel disease, and sickle cell disease, there was some evidence indicating that anxiety was associated with adverse outcomes; supported by two longitudinal studies, one in asthma and one in inflammatory bowel disease. For diabetes, results were inconsistent; with some studies indicating that anxiety was associated with worse and others with better treatment adherence.

CONCLUSION

The prevalence of anxiety disorders in youth with CMCs is higher than that in the general population. Anxiety may also be associated with adverse disease-related outcomes for youths, but it is not possible to draw definitive conclusions. Longitudinal studies making use of parent/youth composite anxiety measures and a combination of parent/youth reported and objective measures of disease-related outcomes are needed. Given the burden of disease of anxiety disorders, regardless of the impact on the disease outcomes, screening for and treatment of anxiety is recommended in youths with CMCs.

COPE for asthma: Outcomes of a cognitive behavioral intervention for children with asthma and anxiety

Asthma is the most common childhood chronic condition and a major contributor to school absences and lost instructional time. Children with asthma have a higher risk of internalizing disorders, such as anxiety and depression, which can further complicate asthma management. The purpose of this pilot study was to assess the feasibility, acceptability, and preliminary effects of a manualized, cognitive-behavioral skills-building intervention for children with asthma and anxiety. The design for this study was a one-group, pre/posttest preexperimental with a 6-week follow-up. This article presents the immediate posttest follow-up results. Children between 8 and 12 years of age and their caregivers were recruited from three elementary schools in a large public school district in Ohio. Thirty-two children with asthma and symptoms of anxiety completed the Creating Opportunities for Personal Empowerment (COPE) for Asthma program. Caregivers completed surveys, but they did not participate in the intervention. Results indicated that the program was feasible to implement in small groups during the school day. Self-reported findings indicated a significant reduction in separation anxiety and increased personal beliefs, child-management self-efficacy, and asthma illness representations. Parents and caregivers reported symptom reduction in their children on the Pediatric Symptom Checklist. The subgroup of children scoring high on anxiety at baseline showed reductions with the intervention, having large positive effect sizes for separation and social anxiety as well as medium and large positive effect sizes on the personal beliefs and asthma illness representations, respectively.

Evaluation of neuropsychiatric comorbidities and their clinical characteristics in Chinese children with asthma using the MINI kid tool

Background

The mental health and quality of life in children with asthma have attracted widespread attention. This study focused on the evaluation of mental health conditions and their clinical characteristics in Chinese children with asthma.

Methods

A total of 261 children with asthma aged 6 to 16 years old and 261 age- and gender-matched children from the general population were recruited to participate in this study from Guizhou Provincial People’s Hospital. The parents of all subjects were interviewed using the MINI Kid and were required to finish a clinical characteristics questionnaire. Logistic regression analysis was performed to evaluate risk factors.

Results

The prevalence of mental health conditions in the asthma group was significantly higher than that in the control group (26.4% vs 14.6%, P < 0.001). A total of 10 mental health conditions was identified in the asthma group, the most common of which was ADHD (11.5%; 30/261), followed by oppositional defiant disorder (ODD) (10.7%; 28/261), separation anxiety disorder (6.1%; 16/261), social anxiety disorder (3.8%; 10/261), specific phobias (2.3%; 6/261), agoraphobia without panic (1.5%; 4/261), (mild) manic episodes (1.1%; 3/261), major depressive episodes (MDEs) (0.8%; 2/261), movement (tic) disorder (0.8%; 2/261), and dysthymia (0.4%; 1/261). A total of 6 neuropsychiatric conditions was detected in the control group, including ODD (5.7%; 15/261), ADHD (4.6%; 12/261), social anxiety disorder (3.1%; 8/261), seasonal anxiety disorder (SAD) (2.3%; 6/261), specific phobias (1.1%; 3/261), and agoraphobia without panic (0.4%; 1/261). The prevalence rates of ODD, ADHD, and SAD differed significantly between the two groups (P < 0.05). Multiple regression analysis revealed that severe persistent asthma (OR = 3.077, 95% CI 1.286–7.361), poor asthma control (OR = 2.005, 95% CI 1.111–3.619), and having asthma for > 3 years (OR = 2.948, 95% CI 1.580–5.502) were independent risk factors for the presence of mental health conditions in asthmatic children.

Conclusions

Children with asthma have a higher rate of mental health conditions than non-asthmatic children. Standardized diagnosis and treatment may help reduce the risk of neuropsychiatric conditions.

Comparing Parent and Child Self-report Measures of the State-Trait Anxiety Inventory in Children and Adolescents with a Chronic Health Condition

Anxiety symptoms in children and adolescents with a chronic health condition have been estimated as high as 40% lifetime prevalence. Clinicians often rely on parent/caregiver information to supplement or substitute child self-report related to pediatric physical and mental health. We developed a caregiver proxy version (STAI-P) for the State-Trait Anxiety Inventory (STAI) State Anxiety Scale that was compared with a child self-report version in 201 parent-child dyads to evaluate its utility in measuring state anxiety in chronically ill youth. For patients aged 7-12, self-reports of state anxiety were moderately associated with parent distress and health provider-reported functional status, but negatively associated with parent STAI-P scores. For patients aged 13-17, self-reports of state anxiety were significantly associated with STAI-P scores, parent distress, and health provider-reported functional status. The STAI-P parent version may be a useful tool in identifying and addressing anxiety symptoms in youth living with a chronic health condition.

Allergies, asthma, and psychopathology in a nationally-representative US sample

BACKGROUND

Symptoms of depressed mood and anxiety have been associated with immune dysregulation and atopic disorders, however it is unclear whether this relationship spans other forms of psychopathology. The objective of this study was to use a large, population-based sample to examine the association between several common psychiatric conditions and two atopic disorders: seasonal allergies and asthma. This study also examined whether comorbidity between psychiatric disorders confounded the relationship between atopy and each psychiatric disorder.

METHODS

Data come from the Comprehensive Psychiatric Epidemiology Surveys, a nationally-representative sample of US adults (N = 10,309). Lifetime history of major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder (PD), and post-traumatic stress disorder (PTSD) was assessed using the Composite International Diagnostic Inventory. History of seasonal allergies and asthma were assessed by self-report. Weighted logistic regression was used to evaluate the association between allergies and asthma and psychopathology. Psychiatric comorbidities were also examined as potential confounders.

RESULTS

Approximately 36.6% had a history of allergies and 11.5% a history of asthma. Seasonal allergies were positively associated with odds of MDD (Odds ratio (OR): 1.24, 95% Confidence Interval (CI): 1.06-1.46), GAD (OR: 1.54 (1.28-1.84)), PD (OR: 1.54 (1.24-1.91)), and PTSD (OR: 1.32 (1.09-1.59)). Asthma was not significantly associated with any psychiatric disorder. All significant associations persisted after adjustment for psychiatric comorbidities.

LIMITATIONS

Limitations include self-reporting of atopic disorder status and of all disorder ages of onset.

CONCLUSIONS

This study confirms the association between MDD and PD and seasonal allergies, and extends this relationship to GAD and PTSD.

Mothers' emotional states and attitudes regarding their children with asthma

OBJECTIVES

The aim of this study was to investigate the associations of asthma with the psychological profile (depression and anxiety) of children with asthma and their mothers as well as the attitudes of these mothers toward their children and their family relationships.

METHODS

Sixty-four children with asthma, 60 healthy children and their mothers were included in the study. The Children's Depression Inventory (CDI) and Childhood Anxiety Sensitivity Index (CASI) were applied to the children. All mothers completed the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Parental Attitude Research Instrument and the Family Assessment Device.

RESULTS

CASI scores were significantly higher in children with asthma (p < 0.001) than in healthy children. The increasing duration and severity of asthma were associated with increasing anxiety levels in children with asthma. Depression and anxiety scores were significantly higher in the mothers of children with asthma than in the comparison group. The mothers of children with asthma did not have supportive and friendly relationships with their children. In addition, these mothers had significantly higher Attitude of Hostility and Rejection, Attitude of Over-parenting and Authoritarian Attitude scores than those of the comparison group. Increasing duration and severity of asthma influenced family functions and the attitude of the mothers of children with asthma. There was a correlation between an increasing number of emergency department visits and increasing depression in the mothers of children with asthma.

CONCLUSIONS

This cross-sectional study revealed that the disease may negatively affect the lives of children with asthma and their mothers and their family relationships.

Psychosocial Factors in Severe Pediatric Asthma

Asthma is the most common chronic illness among children in the United States and can impact nearly all aspects of functioning. Most research suggests that children with severe asthma display more emotional and behavioral problems than their healthy peers. These psychological difficulties are associated with increased risk for functional impairments and problematic disease course. Multidisciplinary teams that assess and treat these psychosocial factors using psychoeducational and behavioral interventions are important for children whose asthma is poorly controlled. Future research should examine the ways in which stress, emotions, and immune functions interact, so as to develop more preventative interventions.

Anxiety in youth with asthma: A meta-analysis

OBJECTIVES

Anxiety often presents comorbidly with asthma in youth under 18; however, prevalence rates are unclear. The aim of this review was to provide an up-to-date analysis of the literature investigating the prevalence of anxiety disorders, and comparisons of anxiety disorders and symptomatology in youth with asthma, compared to those without.

METHODS

A systematic search was conducted using the databases PsycINFO, MEDLINE, EMBASE, and CINAHL.

RESULTS

The search process produced 15 studies (n = 7443) reporting data on youth with asthma and anxiety disorders, 11 studies (n = 10 332) reporting data on youth with and without asthma and anxiety disorders, and 28 studies (n = 5848) reporting data on youth with and without asthma and anxiety symptomatology. Youth with asthma had an anxiety disorder prevalence rate of 22.7%. Youth with asthma also had a greater number of anxiety disorders, compared to those without asthma (d = 0.37, 95%CI: 0.24-0.50, P < 0.001), and higher levels of anxiety symptomatology than youth without asthma (d = 0.29, 95%CI: 0.19-0.39, P < 0.001).

CONCLUSIONS

Youth with asthma display a prevalence rate for anxiety disorders that is more than three times higher than the prevalence in healthy youth. For the specific anxiety disorders investigated, elevated prevalence rates for youth with asthma were also found. Future research needs to focus on the factors that mediate or predict the development and maintenance of anxiety in youth with asthma and the development of clinically efficacious treatments.

The pro-inflammatory cytokines, salivary cortisol and alpha-amylase are associated with generalized anxiety disorder (GAD) in patients with asthma

Generalized anxiety disorder (GAD) is common in patients with asthma. High levels of GAD may lead both to exacerbation of the condition and poor management. However, the physiological mechanisms of GAD in asthma patient is unclear. This study investigated the associations between the diurnal rhythm of sputum cytokines, salivary cortisol, α-amylase and GAD in asthma patients. Patients with co-morbid GAD and asthma showed higher sputum IL-1 AUC, sputum IL-6 AUC and sAA AUC. And there were positive correlations between Hamilton anxiety scale (HAMA) scores and sputum IL-1 AUC concentrations (r=0.37, P=0.002), HAMA scores and sputum IL-6 AUC (r=0.56, P<0.001), HAMA scores and sAA AUC (r=0.75, P<0.001). Also, there were positive correlations between Sputum IL-1 AUC and sAA AUC (r=0.40, P<0.001), between Sputum IL-6 AUC and sAA AUC. Stepwise multiple regression analyses showed the combination of sputum sAA AUC, IL-1 AUC, IL-6 AUC and cortisol AUC was the best predictor of HAMA scores (ΔR²=0.439, F(4,63)=14.086, p<0.001). Therefore, pro-inflammatory cytokines, salivary cortisol and alpha-amylase may all be involved in the occurrence of GAD in asthma patients.

Predictors of Caregiver Burden among Mothers of Children with Chronic Conditions

Objective: The complex medical regimens of children and adolescents with chronic conditions can have a significant impact on families and households. Caregivers may experience burden, which can lead to negative health consequences and poor quality of life. The objective of this study was to determine child-related predictors and risk factors for caregiver burden among parents of children with chronic conditions. Methods: We distributed an institutional review board (IRB)-approved, online cross-sectional survey to parents of children who attended the Victory Junction therapeutic camp. Parents provided information on child demographics, disease characteristics, and healthcare utilization. Parents also answered the adapted Zarit Burden Interview, which measured caregiver burden. Children completed scales about self-management and self-efficacy. Linear regression analyses determined how children’s disease characteristics, health utilization, and self-management skills were associated with caregiver burden. Results: We enrolled 150 mother-child dyads. The mean age of child participants was 12.23 years (±2.5), with an age range of 6 to 16 years. It was determined that children’s number of medicines and injections (β = 0.161, p = 0.047), a diagnosis of attention-deficit/hyperactivity disorder (ADHD) in addition to the primary medical condition (β = 0.216, p = 0.008), frequent visits with a primary care provider (PCP) (β = 0.209, p = 0.026) and emergency room (ER) visits (β = 0.197, p = 0.038), and lower child self-efficacy (β = −0.241, p = 0.041) were predictors of increased caregiver burden. Conclusions: We identified risk factors for caregiver burden among mothers. Future studies should explore additional child-related characteristics as they relate to caregiver burden, and should determine if interventions for mothers of children with chronic conditions can lead to positive outcomes.

Functioning Among Youth with Comorbid Mood Disorder and Chronic Physical Illness in Public Sector Care

OBJECTIVE

The current study examines parent/caregiver and youth report of psychosocial and health-related functioning among youth served in public systems of care, with mood disorder only, comorbid mood disorder and chronic physical illness, and chronic physical illness only.

METHOD

Participants were 539 youths (ages, 11-18; 64% male) with a mood disorder and/or chronic physical illness enrolled in a study of public sector care. Presence of mood disorder was based on youth report on the Diagnostic Interview Schedule for Children-IV. Parents reported whether they had been told by a school or health professional that their child had 1 of 8 categories of chronic physical illnesses. Psychosocial functioning was assessed with the Child Behavior Checklist and Youth Self Report. Parent and child versions of the Child Health Questionnaire assessed health-related functioning. Covariates included demographic variables, substance use, mental health service utilization, disruptive behavior disorders, and anxiety disorders. Multivariate analysis of covariances assessed differences on outcome measures among the 3 groups.

RESULTS

Parents and youths reported significantly worse psychosocial and health-related functioning for youth with comorbid mood and physical illnesses. Generally, parents reported lower functioning in youth with a physical illness compared with mood disorder, and youth with mood disorders reported lower functioning than those with physical illness.

CONCLUSION

Youth with comorbid mood disorder and chronic physical illness experience high levels of impairment. Increased screening of mood disorders in pediatric health settings is warranted. Health systems, clinics, and clinicians should focus on integrating mental and physical health diagnosis and treatment.

Health Issues in Hispanic/Latino Youth

This review focuses on obesity, asthma and mental health functioning as salient health issues affecting Hispanic youth. Burden of these conditions and consequences for adult health are also discussed. Hispanic youth are affected by obesity at an early age; the prevalence of obesity among Hispanic children 6-11 years old is twice as high as the prevalence for non-Hispanic White children of the same age, but among 2-5 years old is 4 times higher. Asthma disproportionally affects certain Hispanic groups, notably children of Puerto Rican ancestry, and the comorbidity of asthma and obesity is an emerging health issue. Another area of concern is the scant data on mental health functioning among Hispanic youth. Research on Hispanic youth mental health have reported high rates of depressive symptomatology and high rates of alcohol use among Hispanic adolescents but despite these findings, they have inadequate access to mental health services. This review highlights the need for better data to gain a better understanding of the health status of Hispanic youth and help develop preventive programs that addresses the need of this population. Improving access to health services, in particular mental health services, is also a crucial aspect.

The Role of the Microbiome in the Relationship of Asthma and Affective Disorders

The effect of stress, anxiety and other affective states on inflammatory conditions such as asthma is well documented. Although several immune pathway mechanisms have been proposed and studied, they cannot fully explain the relationship. In this chapter we present a new perspective on asthma development and exacerbation that integrates findings on the role of psychological factors in asthma with the microbiome and the hygiene hypothesis in asthma development.

The association of childhood asthma with mental health and developmental comorbidities in low-income families

OBJECTIVE

The objective of the study was to determine the relationship of childhood asthma with mental health and developmental indicators in low-income families.

METHODS

Parents/guardians of approximately 400 children, aged 2-14 years, were recruited from a charity hospital serving low income neighborhoods in the outskirts of Karachi, Pakistan. Mothers of children were interviewed in their local language by a trained nurse. Eight self-reported comorbidities were grouped into two constructs based on factor analysis and conveniently labeled as mental health (anxiety, attention and behavioral problems) and developmental problems (learning, developmental delay, hearing impairment, sleep and speech problems). Data were analyzed using multiple logistic regression, adjusted for age, sex, presence of older siblings, number of people in the household, child birth weight, presence of mold, and family history of asthma or hay fever.

RESULTS

Children with asthma had 18 times greater odds of mental health problems (adjusted OR = 18.0, 95% CI: 9.2, 35.1) as compared to children without asthma. The odds of developmental problems were more than 14 times greater for children with asthma (adjusted OR = 14.3, 95% CI: 7.8, 26.1) as compared to children without asthma.

CONCLUSIONS

This study found mental and developmental adverse consequences of childhood asthma in low-income families. Identifying and treating asthma at an early age could reduce the burden of comorbidities in this population.

Do Panic Symptoms Affect the Quality of Life and Add to the Disability in Patients with Bronchial Asthma?

Background. Anxiety and panic are known to be associated with bronchial asthma with variety of impact on clinical presentation, treatment outcome, comorbidities, quality of life, and functional disability in patients with asthma. This study aims to explore the pattern of panic symptoms, prevalence and severity of panic disorder (PD), quality of life, and disability in them. Methods. Sixty consecutive patients of bronchial asthma were interviewed using semistructured proforma, Panic and Agoraphobia scale, WHO Quality of life (QOL) BREF scale, and WHO disability schedule II (WHODAS II). Results. Though 60% of the participants had panic symptoms, only 46.7% had diagnosable panic attacks according to DSM IV TR diagnostic criteria and 33.3% had PD. Most common symptoms were “sensations of shortness of breath or smothering,” “feeling of choking,” and “fear of dying” found in 83.3% of the participants. 73.3% of the participants had poor quality of life which was most impaired in physical and environmental domains. 55% of the participants had disability score more than a mean (18.1). Conclusion. One-third of the participants had panic disorder with significant effect on physical and environmental domains of quality of life. Patients with more severe PD and bronchial asthma had more disability.

Assessing anxiety in nonhuman primates

Anxiety can be broadly described as a psychological state in which normally innocuous environmental stimuli trigger negative emotional expectations. Human anxiety disorders are multidimensional and may be organic or acquired, situational or pervasive. The broad ranging nature of the anxiety phenotype speaks to the need for models that identify its various components and root causes to develop effective clinical treatments. The cross-species comparative approach to modeling anxiety disorders in animals aims to understand mechanisms that both contribute to and modulate anxiety. Nonhuman primate models provide an important bridge from nonprimate model systems because of the complexity of nonhuman primates' biobehavioral capacities and their commonalities with human emotion. The broad goal of this review is to provide an overview of various procedures available to study anxiety in the nonhuman primate, with a focus on the behavioral aspects of anxiety. Commonly used methods covered in this review include assessing animals in their home environment or in response to an ethologically relevant threat, associative conditioning and startle response tests, and cognitive bias tests. We also discuss how these procedures can help veterinarians and researchers care for captive nonhuman primates.

Association between mental disorders and physical diseases in adolescents from a nationally representative cohort

OBJECTIVE

Pediatric health care and research focus mostly on single morbidities, although the single-disease framework has been challenged. The main objective was to estimate associations between childhood mental disorders and physical diseases.

METHODS

This study is based on weighted data (n = 6482) from the National Comorbidity Survey Replication Adolescent Supplement (age, 13-18 years). Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition lifetime mental disorders were assessed using the fully structured World Health Organization Composite International Diagnostic Interview, complemented by parent report. Lifetime medical conditions and doctor-diagnosed diseases were assessed by adolescent self-report.

RESULTS

Of 6469 participants, 2137 (35.33%) reported at least one mental disorder and one physical disease. The most substantial associations included those between affective disorders and diseases of the digestive system (odds ratio [OR] = 3.46, 95% confidence interval [CI] = 2.28-5.24), anxiety disorders and arthritis (OR = 2.27, CI = 1.34-3.85), anxiety disorders and heart diseases (OR = 2.41, CI = 1.56-3.73), anxiety disorders and diseases of the digestive system (OR = 2.18, CI = 1.35-3.53), and eating disorders and epilepsy/seizures (OR = 5.45, CI = 1.57-18.87). Sociodemographic factors did not account for the association between mental disorders and physical diseases.

CONCLUSIONS

Findings suggest that mental disorders and physical diseases often co-occur in childhood. This association is a major public health challenge, and the child health system needs additional strategies in patient-centered care, research, medical education, health policy, and economics to develop well-coordinated interdisciplinary approaches linking mental and physical care in children.

The Common Sense Model in early adolescents with asthma: longitudinal relations between illness perceptions, asthma control and emotional problems mediated by coping

OBJECTIVE

The present study examined the longitudinal relations between illness perceptions and asthma control and emotional problems (i.e., anxiety, depression, stress), respectively, in adolescents with asthma. Furthermore, the mediating effects of asthma-specific coping strategies on these relations were examined, as specified in the Common Sense Model (CSM).

METHODS

In 2011, 2012, and 2013, adolescents (aged 10-15) with asthma were visited at home (N=253) and completed questionnaires about their illness perceptions, asthma-specific coping strategies, asthma control, symptoms of anxiety and depression, and perceived stress. Path analyses were used to examine the direct relations of illness perceptions with asthma control and emotional problems and the mediating effects of coping strategies cross-sectionally and longitudinally.

RESULTS

Perceptions of less perceived control and attributing more complaints to asthma were associated with better asthma control. Perceptions of more concern, less coherence, and increased influence of asthma on emotional well-being were associated with more emotional problems. Longitudinally, perceptions of more treatment control and fewer concerns predicted less emotional problems over time. More worrying mediated the cross-sectional relation between perceiving more concern about asthma and less asthma control and the longitudinal relation between perceiving more concern about asthma and more emotional problems.

CONCLUSION

Illness perceptions were associated with asthma control and emotional problems; however, over time, illness perceptions only predicted changes in emotional problems. Most coping strategies did not mediate the relation between illness perceptions and outcomes. Interventions aimed to change illness perceptions in adolescents with asthma could decrease emotional problems.

Psychiatric comorbidities in Asian adolescent asthma patients and the contributions of neuroticism and perceived stress

PURPOSE

Psychiatric comorbidity is reported to be common among adolescents with asthma, but little is known about its underlying psychological factors.

OBJECTIVE

This study explored the profile of anxiety and depressive comorbidities among adolescents with well-controlled and poorly controlled asthma and the contribution of neuroticism and perceived stress.

METHODS

The Revised Child Anxiety and Depression Scale, Neuroticism subscale of Big Five Inventory, Perceived Stress Scale, and Asthma Control Test were administered to 198 adolescents (aged 12-19 years) with well-controlled (n = 137) and poorly controlled asthma (n = 61) as well as 171 healthy neighborhood controls.

RESULTS

Adolescents with poorly controlled asthma, compared with well-controlled asthma patients and healthy controls, had higher scores of depression (p = .006), panic attacks (p = .002), total anxiety (p = .038), and total internalizing symptoms (p = .017), after adjusting for gender, age, ethnicity, smoking status, and family housing type. Adolescents with asthma had higher neuroticism (p = .025), perceived stress (p = .022), and body mass index (p = .006) and lower self-rated health (p < .001) than healthy controls. No significant differences in psychiatric comorbidity scores were observed after accounting for differences in underlying psychological and physical factors. Among asthma patients, increased asthma control was associated with decreased scores of psychiatric comorbidity (p < .01), but the association was not significant after allowing for decreased neuroticism and perceived stress.

CONCLUSIONS

The diagnosis of asthma and poor asthma control in adolescents is associated with excess psychiatric comorbidity, which is likely due to increased neuroticism and perceived stress.

Global health benefits of being raised in a rural setting: results from the National Comorbidity Survey

AIM

The aim of this study was to examine the association between being raised in a rural setting and physical and mental health among adults in the USA.

METHODS

Data were drawn from the National Comorbidity Survey (n = 8098), a household probability sample representative of adults aged 15-54 years in the USA. Multiple logistic regression analyses were used to determine the association between being raised in a rural area and the likelihood of mental disorders, physical disorders, suicide behavior, and parental mental health. Odds ratios (OR) with 95% confidence intervals were calculated, adjusting for differences in demographic characteristics.

RESULTS

Being raised in a rural setting was associated with decreased odds of ulcer (OR = 0.56 [0.34, 0.91]). Mental disorders (any lifetime) (OR = 0.74 [0.64, 0.85]), any anxiety disorder (OR = 0.75 [0.6, 0.92]) and any substance use disorder (OR = 0.79 [0.65, 0.94]) were significantly less likely among adults who were raised in a rural setting. Maternal psychopathology and exposure to trauma were significantly lower among those raised in a rural setting, compared with those who were not. These relations were not explained by sociodemographic differences.

CONCLUSIONS

These data provide preliminary evidence that being raised in a rural environment lowers the risk of mental and physical health problems in adulthood. Being raised in a rural community also appears to be associated with significantly lower likelihood of exposure to trauma and maternal psychopathology. Future studies that can identify potential protective factors and mechanisms underlying these pathways are needed next.

Asthma and mental health among youth in high-risk service settings

OBJECTIVE

To investigate the prevalence of asthma and mental health problems among representative samples of youth in high-risk service settings and the community, and to examine the relationship between asthma and mental health in these groups.

METHODS

Data were drawn from the Alternative Service Use Patterns of Youth with Serious Emotional Disturbance Study (SED) (n = 1181), a combined representative, cross-sectional sample of youth in various clinical settings and the community. Multiple logistic regression analyses were used to examine the association between asthma and mental disorders. Demographic characteristics were investigated as potential confounders.

RESULTS

Asthma was common among 15.2% of youth in service settings and 18.8% of youth in the community. The prevalence of mental disorders was extremely high among youth with and without asthma in all service settings, and asthma was associated with increased prevalence of mental disorders among youth in the community, but not among youth in service settings. The relationship between asthma and internalizing disorders among youth in the community does not appear entirely attributable to confounding by demographics.

CONCLUSIONS

Findings are consistent with and extend previous data by showing that both asthma and mental disorders are disproportionately common among youth in high-risk service settings. Almost half of youth with asthma in service settings meet diagnostic criteria for a mental disorder. Clinicians and policy makers who are responsible for the health care of youth in these high-risk groups should be aware that asthma is common, and that the prevalence of internalizing disorders are especially common among those with asthma.

Inflammation in children and adolescents with neuropsychiatric disorders: a systematic review

OBJECTIVE

There has been rapid growth in research regarding inflammation in neuropsychiatric disorders as it relates to youth. We therefore set out to systematically review the literature on inflammation and neuropsychiatric disorders in children and adolescents.

METHOD

A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were included if proinflammatory markers (PIMs) in children and/or adolescents with neuropsychiatric disorders were measured.

RESULTS

Sixty-seven studies were included, involving 3,952 youth. Evidence for a proinflammatory state is strongest for autism spectrum disorders (ASD). PIMs are elevated in children and adolescents with major depressive disorder (MDD), bipolar disorder (BD), post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), Tourette's disorder (TD), attention-deficit/hyperactivity disorder (ADHD), and schizophrenia (SZ). However, the data are inconsistent. Evidence for specific PIMs is equivocal at this stage, although the findings in youth with MDD, BD, and PTSD converge with the extant adult literature in these areas. Definitive conclusions are limited by methodologic factors including cross-sectional and retrospective study design, between-study differences in specific markers and methods of analysis, small sample size, and other sources of heterogeneity.

CONCLUSION

The literature regarding inflammation among children and adolescents with neuropsychiatric disorders represents nearly 4,000 youth. There is preliminary evidence for elevated markers of inflammation in this population. Larger, prospective studies are needed to realize the goal of inflammatory markers informing clinical practice. In the interim, present findings suggest that further examination of this topic is warranted.

The long-term effects of maternal depression: early childhood physical health as a pathway to offspring depression

PURPOSE

Cross-sectional and retrospective studies have highlighted the long-term negative effects of maternal depression on offspring physical, social, and emotional development, but longitudinal research is needed to clarify the pathways by which maternal depression during pregnancy and early childhood affects offspring outcomes. The current study tested one developmental pathway by which maternal depression during pregnancy might negatively impact offspring mental health in young adulthood, via poor physical health in early childhood.

METHODS

The sample consisted of 815 Australian youth and their mothers who were followed for 20 years. Mothers reported on their own depressive symptoms during pregnancy and offspring early childhood. Youth completed interviews about health-related stress and social functioning at age 20 years, and completed a questionnaire about their own depressive symptoms 2 to 5 years later.

RESULTS

Path analysis indicated that prenatal maternal depressive symptoms predicted worse physical health during early childhood for offspring, and this effect was partially explained by ongoing maternal depression in early childhood. Offspring poor physical health during childhood predicted increased health-related stress and poor social functioning at age 20. Finally, increased health-related stress and poor social functioning predicted increased levels of depressive symptoms later in young adulthood. Maternal depression had a significant total indirect effect on youth depression via early childhood health and its psychosocial consequences.

CONCLUSIONS

Poor physical health in early childhood and its effects on young adults' social functioning and levels of health related stress is one important pathway by which maternal depression has long-term consequences for offspring mental health.

Health care needs of children with Tourette syndrome

To document the impact of Tourette syndrome on the health care needs of children and access to health care among youth with Tourette syndrome, parent-reported data from the 2007-2008 National Survey of Children's Health were analyzed. Children with Tourette syndrome had more co-occurring mental disorders than children with asthma or children without Tourette syndrome or asthma and had health care needs that were equal to or greater than children with asthma (no Tourette syndrome) or children with neither asthma nor Tourette syndrome. Health care needs were greatest among children with Tourette syndrome and co-occurring mental disorders, and these children were least likely to receive effective care coordination. Addressing co-occurring conditions may improve the health and well-being of children with Tourette syndrome. Strategies such as integration of behavioral health and primary care may be needed to improve care coordination.

Asthma and suicidal ideation and behavior among Puerto Rican older children and adolescents

There is growing evidence of a positive association between asthma and suicidal ideation and behavior in the general community, although information on this potential association is scarce among older children and adolescents and Puerto Ricans, groups at risk for both conditions. Data came from wave 3 of the Boricua Youth Study, a longitudinal study of youth in the Bronx and San Juan conducted from 2000 to 2004. Logistic regressions for correlated data (Generalized Estimating Equation) were conducted, with asthma predicting suicidal ideation and behavior among participants 11 years or older. After adjustment for survey design; age; sex; poverty; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, mental disorders; cigarette smoking; and stressful life events, asthma was positively associated with suicidal ideation and behavior among the Puerto Rican older children and adolescents. Public health interventions targeting Puerto Rican older children and adolescents with asthma and future studies investigating potential biological and psychological mechanisms of association are warranted.

Severity and persistence of asthma and mental health: a birth cohort study

BACKGROUND

The goal of the current study was to investigate asthma and mental health among youth in the community, and to consider the role of asthma severity and persistence in this link. Method Data were drawn from the Raine Study, a population-based birth cohort study in Western Australia. Logistic regression models and generalized estimating equations were used to examine the relationship between asthma at age 5 years and the range of internalizing and externalizing mental health problems at ages 5-17 years. Analyses were stratified by asthma severity and persistence, and adjusted for a range of potential confounders.

RESULTS

More severe and persistent asthma at age 5 was associated with significantly increased odds of affective, anxiety, somatic, oppositional defiant and conduct problems at ages 5-17. Mild asthma and remitted asthma were not associated with heightened vulnerability to mental disorders.

CONCLUSIONS

Our results suggest that youth with symptomatic asthma are more likely to suffer from a wide range of mental health problems, and that the likelihood of mental health problems appears to increase as a function of asthma severity. Youth with poorly controlled and/or more severe and persistent asthma may be considered a vulnerable group who might benefit from mental health screening in clinical, school and community settings.

The link between asthma and smoking explained by depressive feelings and self-efficacy

OBJECTIVE

Adolescents with asthma consistently smoke at higher or similar rates as non-asthmatic peers, although smoking might involve more health risks. This study examined possible mechanisms (i.e. depressive feelings and self-efficacy to refrain from smoking) explaining the association between asthma and smoking initiation.

METHODS

An indirect path from asthma to self-efficacy through depressive feelings was examined in two independent samples. Sample 1 consisted of 4531 adolescents (mean age 12.8) and sample 2 consisted of 1289 children (late childhood, mean age 10.1). Data were gathered from maternal and self-report. In the adolescent sample, whether the relationship between depressive feelings at baseline and smoking initiation two years post-baseline runs via self-efficacy was also examined.

RESULTS

Higher amounts of depressive feelings decreased adolescents' self-efficacy to refrain from smoking, which subsequently increased the risk to initiate smoking. A diagnosis of asthma was also associated with higher levels of depressive feelings which in turn decreased self-efficacy. A marginal significant indirect effect was found in the childhood sample.

CONCLUSION

Smoking prevention efforts should start as early as mid to late childhood. The results indicate that focus should be placed on preventing depressive feelings with the aim of increasing children's self-efficacy to refrain from smoking. This is especially important for children and adolescents with asthma.

Asthma and wheezing are associated with depression and anxiety in adults: an analysis from 54 countries

Background. Asthma and depression are important public-health concerns worldwide. While some epidemiologic studies have shown asthma and wheezing to be associated with depression and anxiety, the patterns are unclear at the multinational level due to the lack of cross-study comparability. Our study examined the associations of self-reported asthma diagnosis and current wheezing with self-reported depression diagnosis and 30-day anxiety using an international survey. Methods. Using the 2002 World Health Survey, a standardized international survey conducted by the WHO, we estimated the associations between diagnosed asthma and current wheezing with diagnosed depression and 30-day anxiety via multiple logistic regressions for 54 countries worldwide. Results. Diagnosed depression and 30-day anxiety were associated with diagnosed asthma in 65% and 40% of the countries, respectively. Diagnosed depression and 30-day anxiety were associated with current wheezing in 83% and 82% of the countries, respectively. Conclusions. The association between asthma and depression was generally seen at the global level. These results indicated the importance of addressing the asthma-depression comorbidity as public-health and clinical management priorities, in order to improve the overall health of the countries.

Asthma and mental health among youth: etiology, current knowledge and future directions

Asthma and mental health problems, such as depression, anxiety and behavior disorders, are common among youth and are significant sources of morbidity. There is a consistent association between asthma and anxiety/depression and a less consistent association between asthma and behavior disorders. Possible biological and psychological mechanisms may include inflammatory processes as well as the stress of having to live with a life-threatening condition. Future studies are warranted with longitudinal designs to establish temporality as well as measures of potential confounds. Biological and psychological measures would complement the longitudinal design to further establish causality. In addition, more information on the degree to which asthma and mental health have reciprocal influences on each other over time - and the mechanisms of these relationships - are needed in order to develop more effective intervention strategies to improve asthma control and mental health among those with both.

Childhood respiratory symptoms and mental health problems: the role of intergenerational smoking

OBJECTIVE

The aim of this study was to investigate the potential role of youth smoking, parental cigarette smoking and parental anxiety/depressive disorders in the relationship between respiratory symptoms and mental health problems among youth.

WORKING HYPOTHESIS

Adjusting for both parental smoking and parental anxiety/depressive disorders in the association between respiratory symptoms and mental health problems among young persons will significantly reduce the strength of the observed relationship.

STUDY DESIGN

Prospective cohort study. PATIENT-SUBJECT SELECTION: Data were drawn from a school-based sample of 1709 young persons in Oregon.

METHODOLOGY

Physical and mental health data were collected on youth.

RESULTS

Respiratory symptoms were associated with significantly increased odds of mental health problems among youth. After adjusting for youth smoking, the relationship between respiratory symptoms and depressive disorders was no longer statistically significant. The relationships between respiratory symptoms and anxiety and depressive disorders were no longer significant after adjusting for parental smoking. Parental anxiety/depressive disorders did not appear to influence these relationships.

CONCLUSIONS

These results provide initial evidence that exposure to parental smoking may play a role in the observed co-occurrence of respiratory and mental health problems in youth, and youths' own smoking appears to influence the link with depressive disorders, but not anxiety disorders.

Quality of life and adjustment in youths with asthma: the contributions of family rituals and the family environment

This cross-sectional study explored the relationships among family ritual meaning, cohesion, conflict, and health-related quality of life (both specific to chronic health conditions and in general), and the emotional and behavioral problems reported by youths with asthma. Participants included 149 Portuguese children and adolescents between the ages of 8 and 18 who had been diagnosed with asthma and attended outpatient services at three public hospitals. The results showed that stronger family ritual meaning predicted a more positive family environment (i.e., higher cohesion levels and lower conflict levels), better health-related quality of life, and fewer emotional and behavior problems in youths. Furthermore, family cohesion and conflict mediated the links between family ritual meaning and health-related quality of life, and emotional and behavioral problems. These results did not change after controlling for participant age, gender, and asthma severity. The findings of this study suggest that family ritual meaning contributes to the adaptation of youths with asthma via its positive association with the family environment. The implications for multicontextual interventions with families are briefly discussed with regard to the positive role of family rituals and of their potential as a modifiable factor in families with increased health challenges.

Prevalence of anxiety and depressive symptoms in adolescents with asthma: a meta-analysis and meta-regression

It remains unclear whether anxiety and depressive symptoms are more prevalent in adolescents with asthma when compared with healthy individuals. This meta-analysis aimed to evaluate the difference in the aggregate prevalence of depressive and anxiety symptoms between adolescents with asthma and healthy controls and to explore the underlying moderators that potentially explain the heterogeneity of the effect size. A meta-analysis of published work was performed using the random effects model. The differences in aggregate prevalence of depressive and anxiety symptoms between adolescents with asthma and healthy controls were determined. Meta-regression and subgroup analysis were performed to identify factors that may contribute to heterogeneity. A total of eight studies were eligible for analysis. The aggregate prevalence of depressive and anxiety symptoms was significantly higher among 3546 adolescents with asthma than that of 24,884 controls (depression, 0.27; 95% CI, 0.18.6-0.39 vs. 0.13; 95% CI, 0.09-0.19; anxiety, 0.33; 95% CI, 0.19-0.52 vs. 0.21; 95% CI, 0.12-0.33). The risk of developing depression and anxiety is significantly higher among adolescents with asthma when compared with controls (depression: pooled odds ratio, 2.09; 95% CI, 1.65-2.64; p < 0.001; anxiety: pooled odds ratio, 1.83; 95% CI, 1.63-2.07; p < 0.001). Meta-regression revealed that the proportions of Caucasian (p = 0.008) and smokers (p < 0.001) were significant moderators which explained the significant heterogeneity when comparing the risk of developing depressive symptoms among adolescent asthma patients vs. controls while age, gender, and severity of asthma were not significant. Family doctors, pediatricians, and healthcare providers should formulate strategies to detect depressive and anxiety symptoms in adolescents with asthma and offer psychological interventions to reduce the burden of psychiatric comorbidity.

The longitudinal relationship between parental reports of asthma and anxiety and depression symptoms among two groups of Puerto Rican youth

OBJECTIVES

This study aims to examine the relationship between parental reports of child asthma and levels and slopes of anxiety and depression symptoms among two contrasting groups of Puerto Rican youth, and to determine whether asthma is a special risk above and beyond parents' reports of other youths' medical conditions.

METHODS

Two probability samples of youth in San Juan and Caguas, Puerto Rico (n=673) and in the south Bronx, New York (n=598), and their caretakers were interviewed in three yearly assessments. Parental reports of their children's asthma during each assessment were used to indicate whether youth had intermittent (PR=34%, NY=23%) or persistent (PR=7%, NY=16%) asthma. Youths' depression and anxiety symptoms were assessed using self reports to the DISC-IV. Information on youths' medical comorbidity was gathered through parental reports.

RESULTS

Multilevel analyses adjusting for comorbid medical conditions indicated that parental reports of youths' intermittent and persistent asthma were related to higher levels, but similar slopes, of anxiety and depression among youth in New York. In Puerto Rico, youth with persistent asthma experienced less improvement in anxiety over time than youth without asthma, but no other associations were found.

CONCLUSION

Having asthma, based on parental reports, represents a risk factor for Puerto Rican youths' internalizing symptoms, even after adjusting for comorbid medical conditions. This risk is more pronounced among youth living in New York, which highlights the importance of considering the social context in which youth develop and minority status when examining associations between physical health risk factors and mental health.

Screening for adolescent anxiety disorders in a pediatric emergency department

OBJECTIVES

Adolescence is a time of increasing risk for some anxiety disorders. Scant data exist on adolescent anxiety in emergency department (ED) settings. We sought to characterize select clinical characteristics and health care use associated with anxiety disorders in a pediatric ED.

METHODS

We screened a convenience sample of 100 adolescent-parent dyads presenting to the ED for the presence of child anxiety disorders using the 5-item Screen for Child Anxiety Related Emotional Disorders, parent (SCARED-P) and child (SCARED-C) versions. Additional demographic and clinical data were also collected.

RESULTS

The SCARED-P and SCARED-C screens identified probable anxiety disorder(s) in 26% to 33% of adolescent participants, respectively. Correlates of positive SCARED-C screens were female sex, asthma, presenting complaint involving headache or migraine, and school absenteeism due to physical problems. Correlates of positive SCARED-P screens were lower parental educational level, presenting complaint involving headache or migraine, and more medical specialty and total medical visits. Few anxious adolescents had received mental health services in the past 6 months. In multivariate models, female sex was independently associated with SCARED-C total score, and presenting complaint involving headache or migraine was independently associated with SCARED-P total score.

CONCLUSIONS

The current pilot data suggest that anxiety disorders are more prevalent among adolescent ED patients than among the general population but largely untreated. Several demographic and clinical variables may help to identify occult anxiety disorders. Greater awareness of anxiety disorders in this population may assist in redirecting a pattern of low use of mental health services but higher overall health care use.

Allergic disease in the first year of life is associated with differences in subsequent neurodevelopment and behaviour

BACKGROUND

Recent trials suggest a link between neuropsychological function, atopy and allergic disease particularly in early childhood; however the nature of this association remains unclear.

AIMS

To investigate the relationship between early allergic disease and sensitisation at 12 months of age and neurodevelopmental outcomes at 18 months.

STUDY DESIGN

Linear or binary logistic regression analysis was used to determine whether allergic diseases or sensitization at 12 months of age was a significant predictor of neurodevelopmental test scores at the 18 months.

SUBJECTS

Infants with a maternal history of allergic disease (n=324).

OUTCOME MEASURES

Allergic outcomes at 12 months of age included allergen sensitisation, eczema, IgE-mediated and food allergy, and neurodevelopmental outcomes at 18 included the Bayley Scales of Infant Toddler Development III Edition, the Achenbach Child Behaviour Checklist and the Macarthur Scales of Infant Toddler Development.

RESULTS

Children with any diagnosed allergic disease at 12 months had evidence of reduced motor scores (p=.016), and this was most apparent for a diagnosis of eczema (p=.007). Non-IgE mediated food allergy was significantly positively associated with problem Internalising Behaviours (p=.010), along with a trend for effects on the Social-Emotional composite score for IgE-Mediated food allergies (p=.052). Allergic sensitisation was not independently associated with any effects on neurodevelopmental outcomes.

CONCLUSION

This study provides evidence that an allergic phenotype in infancy is associated with effects on neurodevelopment. Further research is required to investigate the nature of this relationship.

Factors related to emotional responses in school-aged children who have asthma

A systematic review of the literature was performed to answer the following questions (a) What factors contribute to the emotional responses of school-age children who have asthma? (b) What are the potential gaps in the literature regarding the emotional responses of school-age children (ages 6-12) who have asthma? (c) Are children with a lower socioeconomic status (SES) and those who are minorities represented in the literature proportionate to their prevalence? Two main focus areas regarding emotional responses were identified: (a) factors related to children who have asthma and (b) factors related to caregivers of children who have asthma. Internalizing disorders were reported consistently for children and caregivers of children who have asthma. Negative consequences of asthma for children included panic and asthma attacks, missed school days, and behavioral problems. Issues for caregivers included higher levels of anxiety and depressive symptoms, asthma management deficits, and lower caregiver warmth and involvement. Gaps in the literature included separated studies for children ages 6-12, a lack of a standardized method to define SES, studies that were of a more experimental nature, and a disparate number of studies of minority children and caregivers relative to their asthma prevalence.

Psychological considerations of the child with asthma

Asthma, the most common chronic disease in children and adolescents in industrialized countries, is typified by airway inflammation and obstruction leading to wheezing, dyspnea, and cough. However, the effect of asthma does not end with pulmonary changes. Research has shown a direct link between asthma and stress and psychiatric illness, which if untreated results in heightened morbidity and effects on society. The link between asthma and psychiatric illness, however, is often underappreciated by many pediatric and child mental health professionals. This article reviews the diagnosis and treatment of asthma as well as the correlation between asthma and psychiatric illness in children in an effort to improve management and treatment strategies for this prevalent disease.

Treatment of psychological factors in a child with difficult asthma: a case report

Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy. Although it was recognized that he had a number of potential medical complicating factors including allergies, chronic sinusitis, and gastroesophageal reflux, a psychological intervention using hypnosis ultimately appeared to help alleviate his symptoms completely. Thus, psychological evaluation and intervention should be considered early in the course of management of a patient with difficult asthma, because it may help avoid time-consuming and expensive investigations of potential complicating factors, and it may yield rapid improvement in the patient's clinical condition.

Specificity in the association of anxiety, depression, and atopic disorders in a community sample of adolescents

The specificity of relationships between anxiety and depressive symptoms, with each of the major atopic disorders of asthma, allergic rhinitis (AR), and atopic dermatitis (AD) was systematically investigated within a single study sample. Participants included 367 adolescents who participated in a community, longitudinal study investigating risk factors for the development of psychiatric and physical health problems. Mental health symptoms were assessed at 7, 9, 11, and 13 years of age. Lifetime history of atopic disorders was assessed by parent report at age 13. Analysis of variance was used to investigate the specificity of the associations between anxiety and depression, and each of the atopic disorders. Results indicated that anxiety was associated with a lifetime history of atopic disorders as a group. The association was significantly strengthened when controlling for depression and externalizing psychiatric symptoms. Among atopic disorders, "pure" anxiety was associated with asthma and AR, and having both asthma and AR strengthened the association compared to having either disorder alone. The association of "pure" anxiety with asthma and AR is consistent with existing data suggesting a relationship between anxiety and respiratory disorders. Having both asthma and AR appeared to confer an additive "dose effect" on the strength of the association. The lack of an association with depression suggests that other factors may contribute to the differential expression of anxiety and depression with atopic disorders. Findings demonstrate the importance of assessing the impact of co-morbid psychiatric symptoms and atopic disorders within individual studies to determine the specificity of underlying relationships between these conditions.

Youth and Parent Versions of the Asthma-Related Anxiety Scale: Development and Initial Testing

Among adults, anxiety related to asthma has been acknowledged to influence asthma self-management. However, it has not been addressed in pediatric samples and there have been no measures developed to assess asthma-related anxiety in youth or parents. The objective of this study was to develop and test the psychometric properties of novel instruments assessing asthma-related anxiety: the Youth Asthma-Related Anxiety Scale (YAAS) and Parent Asthma-Related Anxiety Scale (PAAS). Scale items were analyzed for content validity. We determined the factor structure using exploratory factor analysis and tested the scales' psychometric properties with 285 Hispanic and African American early adolescents with uncontrolled asthma (mean age=12.8) and their parents (n=230) who participated in a larger randomized control trial testing the efficacy of an asthma intervention; control group families (134 youth and 103 parents) provided follow-up data to assess temporal stability. Both the YAAS and PAAS contained 2 factors with Cronbach alpha coefficients ranging from 0.75 to 0.90. The 2 factors, anxiety about asthma severity and about disease-related restrictions, were highly correlated within each measure. The measures displayed content and construct validity and demonstrated moderate temporal stability over 2-3 months (range: 0.36-0.42). The YAAS and PAAS have adequate psychometric properties and can meaningfully contribute to the assessment of asthma-related anxiety in adolescents and their parents, filling a clinical need in this population.

Young adult outcomes of children growing up with chronic illness: an analysis of the National Longitudinal Study of Adolescent Health

OBJECTIVE

To examine young adult outcomes in a nationally representative US cohort of young adults growing up with a chronic illness.

DESIGN

Secondary analysis of nationally representative data from wave III (in 2001) of the National Longitudinal Study of Adolescent Health.

SETTING

United States.

PARTICIPANTS

The analytic sample comprised 13 236 young adults aged 18 to 28 years at wave III.

MAIN EXPOSURE

Self-report of a chronic physical illness (asthma, cancer, diabetes mellitus, or epilepsy) in adolescence. Respondents with asthma or nonasthmatic chronic illness (cancer, diabetes mellitus, or epilepsy) were compared with individuals without these conditions.

MAIN OUTCOME MEASURES

Self-report of high school graduation, ever having employment, currently having employment, living with a parent/guardian, and ever receiving public assistance.

RESULTS

Three percent of young adults had nonasthmatic chronic illness (cancer, diabetes, or epilepsy), and 16.0% had asthma. Most young adults with chronic illness graduated high school (81.3%) and currently had employment (60.4%). However, compared with healthy young adults, those with nonasthmatic chronic illness were significantly less likely to graduate high school, ever have had employment, or currently have employment and were more likely to receive public assistance. Compared with young adults with asthma, those with nonasthmatic chronic illness again had significantly worse young adult outcomes on all measures.

CONCLUSIONS

Most young adults growing up with a chronic illness graduate high school and have employment. However, these young adults are significantly less likely than their healthy peers to achieve these important educational and vocational milestones.
