The effects of caregiver depression on childhood asthma: Pathways and mechanisms

Contribution of caregiver and child anxiety and depressive symptoms to child asthma-related quality of life

BACKGROUND

Depression and anxiety negatively affect asthma-related quality of life (QoL). Yet, little is known regarding mood and asthma-related factors that best uniquely explain asthma-related QoL in children.

OBJECTIVE

This cross-sectional study evaluated the unique variance explained by caregiver and child depressive and anxiety symptom severity in child asthma-related QoL, apart from that explained by demographics and asthma control.

METHODS

Children aged 7 to 17 years with asthma (n = 205) and their caregivers with major depressive disorder were included. A 3-stage hierarchical linear regression analysis was conducted with the Pediatric Asthma Quality of Life Questionnaire total scores considered as the outcome. Predictors included demographic characteristics (stage 1); asthma control assessed by the Asthma Control Test (stage 2); and caregiver depression and anxiety (Hamilton Rating Scale for Depression and the Spielberger State/Trait Anxiety Scale) and child depression and anxiety (Children's Depression Inventory and the Screen for Child Anxiety-Related Disorders) (stage 3).

RESULTS

Demographic characteristics accounted for only 5.5% of the Pediatric Asthma Quality of Life Questionnaire scores. Asthma control significantly increased variance explained in QoL to 32.6%, whereas caregiver and child depression and anxiety symptoms significantly increased variance explained to 42.6%. Child anxiety was found to uniquely explain the largest proportion of variance in QoL (rs2 = 0.584).

CONCLUSION

After adjusting variance in QoL for demographic characteristics and asthma control, caregiver and child depression and anxiety measures significantly increased the proportion of variance explained in a child's asthma-related QoL. In addition to better asthma control, child and caregiver depression and anxiety should be addressed to increase child asthma-related QoL.

Effects of comorbid asthma and eczema on child and family quality of life

Paediatric chronic health conditions are associated with poorer psychological wellbeing and quality of life for children and families. This study investigated differences in child and parent/family quality of life between families of children with asthma only, eczema only, or both asthma and eczema, and tested predictors of child and parent/family quality of life. A convenience sample of 106 families completed parent-report measures of child and parent/family quality of life, child emotional and behavioural difficulties, parent adjustment and parenting practices. Between-groups ANOVAs indicated no differences for child quality of life, whereas parent/family quality of life was worse for those with eczema only compared to asthma only. Multiple linear regression revealed that child emotional difficulties predicted worse child quality of life, whereas worse parent adjustment, child emotional difficulties and eczema only (compared to both asthma and eczema) predicted worse parent quality of life. Results suggest that families of children with eczema may be at particular risk for impaired parent/family quality of life. Interventions that take a family-centred approach to improving child and parent adjustment should be investigated as an adjunct to medical treatment to reduce the impact of chronic health conditions on quality of life for children and families.

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.

The biobehavioral family model and the family relational assessment protocol: Map and GPS for family systems training

The Biobehavioral Family Model (BBFM) was developed and evolved as a heuristic research model to support the investigation of pathways by which family relational function impacts individual family member wellbeing and disorder. Recently, the BBFM and its related assessment approach, the Family Relational Process Assessment Protocol (FRAP), have emerged as tools for clinical practice and training. The BBFM model will be presented, along with definitions of the dimensions constructed in the model, and research evidence in support of the model. To illustrate how the BBFM and FRAP are used in training, instructions for conducting the FRAP will be presented. Then, transcripts from two contrasting families participating in one of the interaction tasks will illustrate how, in training, the FRAP is interpreted through the BBFM lens to illuminate how these patterns of family relationship impact the identified patient. Finally, three applications of this training approach will exemplify the use of the BBFM and FRAP in the context of a Child and Adolescent Psychiatry Fellowship, a Family Medicine Fellowship, and a Family Therapy Training Program in Istanbul, Turkey. Limitations and future directions for the application of the BBFM in the exploration of multicultural aspects of family function for clinical and training purposes will be discussed.

Associations of allergy-related outcomes with depression in the US adults

Evidences showed the link between allergy and depression, while the relationships of depression with allergy-related outcomes is insufficient. The objective of this study is to evaluate and compare the relationship of depression with allergy-related outcomes assessed using two different outcome indicators, in a population-based study. A cross-sectional study was performed of 1094 participants in the 2005-2006 National Health and Nutrition Examination Survey (NHANES). The self-reported allergic symptoms of allergic rhinitis (AR) status and immunoglobulin E (IgE) were used to evaluate the allergy-related outcomes. The depression disorder was defined as the ≥ 10 points on the Patient Health Questionnaire-9. Logistic and linear regression models were performed to illustrate the associations of depression and allergy-related outcomes. The prevalence of AR and depression was 34.2% and 6.8%, respectively. The odds of depression were 8.6% higher in participants with AR patients compared those without AR [odds ratio (OR) = 1.739, 95% confidence interval (CI): (1.034, 2.933)], while the odds of depression in participants with allergic sensitization and without allergic sensitization were not found significant difference. Allergy is positively associated with depression disorder, and patients with allergy-related outcomes, such as AR, may be at higher risk of depression, while the IgE level was not founded to be related with depression. In the treatment of AR patients with depression symptoms, early detection and management of mental problems are of importance.

Implementation of caregiver depression screening in an urban, community-based asthma clinic: a quality improvement project

OBJECTIVE

Caregiver depressive symptoms are prevalent among children with asthma and associated with greater asthma morbidity. Identifying caregivers with depression and connecting them to appropriate treatment may reduce child asthma morbidity. The goal of this project was to implement a workflow for caregiver depression screening and treatment referral in an urban, community-based, asthma clinic serving under-resourced children.

METHODS

The Model for Improvement with weekly Plan-Do-Study-Act cycles was utilized. A two-item depression screening tool (Patient Health Questionnaire-2; PHQ-2) and an acceptability question using a 5-point Likert scale were added to an existing social needs screening checklist administered to all caregivers during the child's clinic visit. Caregivers with a positive PHQ-2 score (≥3) received the PHQ-9. Positive screens on the PHQ-9 (≥5) received information and referrals by level of risk. PHQ-9 positive caregivers received a follow-up phone call two weeks post-visit to assess connection to support, improvement in depressive symptoms, and satisfaction with resources provided.

RESULTS

The PHQ-2 was completed by 84.4% of caregivers (233/276). Caregivers had a mean age of 33.8 years (SD = 8.3; Range: 18-68) and were predominately female (86.4%), Black (80.4%), and non-Hispanic (78.4%). The majority (72.3%) found the screening acceptable (agree/strongly agree). Nearly one in six caregivers (37/233, 15.9%) reported depressive symptoms (PHQ-2 ≥ 3); 11.6% (27/233) had clinically significant symptoms (PHQ-9 score ≥ 10); and 2.1% (5/233) reported suicidal thoughts. Of those with depressive symptoms, 70.3% (26/37) participated in the follow-up phone call. While 50% (13/26) reported the resources given in clinic were "extremely helpful," no caregivers contacted or used them.

CONCLUSIONS

Caregiver depression screening was successfully integrated into a pediatric asthma clinic serving under-resourced children. While caregivers found screening to be acceptable, it did not facilitate short-term connection to treatment among those with depressive symptoms.

Childhood Asthma and Parental Antidepressant Use in a Nationwide Danish Cohort

Background

Paediatric asthma is associated with caregiver depression, which in turn is associated with poor asthma control. Although sociodemographic risk factors are associated with parental depression among children with asthma, the contribution of these factors to caregiver depression in free-to-access universal healthcare settings is unknown.

Methods

The association between childhood asthma and parental antidepressant use was investigated in a Danish nationwide cohort of children aged 2-17 years that redeemed inhaled corticosteroids in 2015. The odds of antidepressant use were estimated in comparison to control families that were matched 1:1 on the number of siblings, residence, income, and education.

Results

Among the families of 28,595 children with actively treated asthma, 12% of mothers and 6.2% of fathers were on antidepressant therapy, compared to 9.3% and 5.3% in controls (p<0.001). Paediatric asthma was associated with increased odds of parental antidepressant use (OR 1.29 (1.23-1.35)), even after adjusting for parental asthma. Poor asthma control, but not higher asthma severity, was associated with higher odds of antidepressant use (1.43 (1.31-1.56)). Compared with the controls, families with two or more children with asthma had higher OR (1.42 (1.29-1.56)) than those with a single child (OR 1.27 (1.21-1.34)). Low socioeconomic status was associated with parental antidepressant use.

Conclusion

Caregiver depression in a Danish cohort is more prevalent among mothers than among fathers and is associated with poor asthma control in children. Antidepressant use among caregivers was associated with total family asthma burden and was independent of socioeconomic status.

New Caregiver Diagnoses of Severe Depression and Child Asthma Controller Medication Adherence

BACKGROUND AND OBJECTIVES

Children with asthma who have depressed caregivers are known to be less adherent to medication regimes. However, it is less clear how adherence responds to a caregiver's new diagnosis of severe depression or whether there is a similar relationship with other serious caregiver diagnoses. The hypothesis is that adherence worsens both with new diagnoses of depression and possibly with new diagnoses of other serious conditions.

METHODS

This study follows a cohort of 341,444 continuously insured children with asthma before and after a caregiver's new diagnosis of severe depression or another serious health condition. The effect of a new depression diagnosis on a child's medication adherence is compared to the effect of new diagnoses of other common caregiver chronic conditions including diabetes, cancer, congestive heart failure, coronary artery disease, and chronic obstructive pulmonary disease.

RESULTS

Results show that children's medication adherence declines following a caregiver's new diagnosis of severe depression, but that it also declines following a caregiver's new diagnosis of diabetes. There is no association with new diagnoses of the other caregiver chronic conditions examined.

CONCLUSIONS

Children whose caregivers have a new diagnosis of depression or diabetes may be at increased risk of deterioration in their medication adherence. These caregivers may benefit from additional support and follow-up. The relationship between caregivers' health and children's medication adherence is complex and deserves further study.

Stressful life events, caregiver depressive symptoms, and child asthma symptom-free days: a longitudinal analysis

OBJECTIVE

To examine relationships among stressful life events (SLE), caregiver depression, and asthma symptom free days (SFDs) in publicly insured Black children aged 4-12 years with persistent asthma.

METHODS

Secondary analysis of longitudinal data from a clinical trial assessing the efficacy of a six-month parental stress management intervention. Using repeated measures Poisson regression, we constructed four models of SLE (Rochester Youth Development Stressful Life Events scale-Parent Items), caregiver depression (Center for Epidemiologic Studies Depression scale ≥ 11), and child asthma symptom-free days (SFDs) in the prior 14 days.

RESULTS

There was no association between SLE and child SFDs, but there was for caregiver depression (Incidence Rate Ratio [IRR]: 0.904; 95% CI 0.86-0.95). The interaction between SLE and caregiver depression was not significant. A specific SLE (recent serious family accident or illness) predicted fewer child SFDs (IRR: 0.91, 95% CI: 0.85-0.98). In the interaction model between caregiver depression and recent accident/illness, caregiver depression was associated with fewer child SFDs (IRR: 0.95, 95% CI: 0.91-0.99) as was the interaction between caregiver depression and recent accident/illness (IRR: 0.77, 95% CI 0.66-0.91); but the relationship between recent accident/illness and child SFDs was not (IRR: 1.00, 95% CI, 0.92-1.09), meaning accident/illness was only associated with fewer child SFDs among depressed caregivers.

CONCLUSIONS

In a sample of publicly insured Black children with persistent asthma, caregiver depression was negatively associated with child SFDs while overall SLE were not. A recent family accident or illness was negatively associated with child SFDs only when the caregiver was depressed.

Asthma, the central nervous system, and neurocognition: Current findings, potential mechanisms, and treatment implications

Accumulating behavioral evidence suggests that asthma is associated with cognitive deficits. A number of studies have identified potential biological contributions to cognition in asthma; however, mechanistic pathways of central nervous system (CNS) involvement in asthma are yet to be established. We therefore conducted a literature review to identify studies examining potential CNS contributions to cognition in asthma. In this review, we discuss our general understanding of the CNS in asthma in the context of cognitive performance and outline a working model of mechanistic pathways linking the proposed neural influences of asthma pathology with cognition. To this extent, we incorporate neural, behavioral, psychological, social and environmental factors. Finally, we underscore the clinical significance of the CNS and neurocognitive sequelae in asthma, highlighting potential opportunities for routine monitoring, therapeutic intervention, and recommend key areas for future research.

Medication Adherence and Common Barriers for Caregivers of Preschool Children with Pediatric Glaucoma

Purpose. To investigate the medication adherence among caregivers of preschool children with pediatric glaucoma and to elucidate common barriers leading to poor adherence. Methods. A cross-sectional study. Caregivers of preschool children with pediatric glaucoma completed a questionnaire on demographic information of caregivers, demographic and disease characteristics of children, caregivers-reported medication adherence (by an adapted Morisky Adherence Scale), and possible 13 barriers. Results. Overall 132 questionnaires were considered valid. Thirty-six percent of all reported poor medication adherence. Caregivers’ age and self-evaluated knowledge about pediatric glaucoma showed a significant difference between the adherent and nonadherent groups ( $P<0.05$ ). Nineteen percent of all reported only one barrier as important, 65% cited multiple barriers, and 16% cited no barriers. Anxiety and depression were cited as important by most caregivers in both groups. Univariate logistic regression analysis demonstrated that difficulty with the acquisition of medications (OR, 2.5; 95% CI, 1.1–5.7; $P=0.025$ ), difficulty with medication schedule (OR, 2.3; 95% CI, 1.0–5.0; $P=0.043$ ), and high expenses for medications (OR, 4.8; 95% CI, 1.4–15.9; $P=0.011$ ) were significantly associated with higher odds of poor adherence. Conclusions. Over one-third of caregivers of preschool children with pediatric glaucoma were in poor medication adherence. Nearly two-thirds of caregivers cited multiple barriers simultaneously as important hindrances to medication usage. Anxiety and depression, difficulty with the acquisition of medications, difficulty with the medication schedule, and high expenses for medications were prominent barriers. Individualized solutions should be provided according to reported barriers by each caregiver and the other most common barriers.

An application of the Biobehavioral Family Model: Examining the impact of maternal depression on child asthma mediated by insecure attachment and child depression

OBJECTIVE

Child asthma disparities are prevalent in socio-economically stressed single-parent families. Stress impacts childhood asthma mediated by immune and autonomic pathways, but specific family stress pathways are not well established. This study tests the hypothesis, derived from a version of the Biobehavioral Family Model, that single parent maternal depression impacts child asthma mediated by insecure attachment and child depression.

METHODS

In a cross-sectional study, children with asthma (age 7-17 years old) from a socio-economically disadvantaged population and their single parent mothers (N = 202) were assessed for depression and attachment security. Child asthma disease activity was assessed by symptom report and lung function tests. Structural equation modeling (SEM) was used to test a model in which caregiver depression impacts child asthma disease activity mediated by insecure attachment and child depression.

RESULTS

SEM results indicated that maternal depression statistically predicted child depression (β = 0.21, p < 0.01) and insecure mother-child attachment (β = 0.17, p < 0.05). In addition, insecure attachment statistically predicted child depression (β = 0.50, p < 0.001). Child depression mediated the adverse effects of maternal depression and insecure attachment on child asthma disease activity (β = 0.43, p < 0.01). There was no direct effect of insecure attachment on child asthma.

CONCLUSION

In single-parent families, maternal depression may impact child asthma disease activity, mediated serially by insecure attachment and child depression. Longitudinal and/or intervention studies are needed to establish a causal effect. These findings suggest that caregiver depression and parent-child relationships may be important targets for family intervention. These interventions may help improve child asthma outcomes and reduce health disparities.

Impact of caregiver depression on child asthma outcomes in Mexicans and Puerto Ricans

OBJECTIVE

Examine whether caregiver depressive symptoms at baseline predict longitudinal child asthma outcomes in the two populations with the largest asthma disparities: Mexicans and Puerto Ricans.

METHODS

Two hundred and sixty-seven Hispanic caregiver-child dyads (Mexican = 188, Puerto Rican = 79; children 5-12 years) were recruited from clinics and hospitals in Phoenix, AZ and the Bronx, NY. The Center for Epidemiological Studies Depression Scale assessed caregiver depressive symptoms; higher scores indicate greater depressive symptomology. Medical records verified child asthma diagnosis. Assessments for outcome variables occurred at baseline, 3, 6, 9, and 12-month follow-ups. Pulmonary function was measured by spirometry, asthma control was measured by the Asthma Control Test, steroid bursts and acute healthcare utilization were assessed by caregiver report and medical records, and adherence was measured by doser devices on controller medications. Structural equation modeling analyzed baseline caregiver depressive symptoms as a predictor of longitudinal child asthma outcomes, and differences between subgroups.

RESULTS

Higher caregiver depressive symptoms predicted better pulmonary function (β = .02, p = .001) in Mexican children, and fewer steroid bursts (β = -.41, p = .01) and better medication adherence (β = .02, p = .07) in Puerto Rican children. Caregiver depressive symptoms did not predict pediatric asthma control or acute healthcare utilization in either subgroup.

CONCLUSIONS

Caregiver depressive symptomology had unexpected effects on child asthma outcomes. Results may be explained by the Hispanic paradox, caregiver resilience, acculturation, and the study's longitudinal nature. Further research is needed on social determinants of health that may influence differences in child asthma outcomes in heterogeneous Hispanic communities.

Bi-directional associations between depressive symptoms and asthma in middle-aged and elderly adults in China

BACKGROUND

There is currently no evidence of an association between depressive symptoms and asthma among older adults in China. We explored the bi-directional associations between depressive symptoms and asthma, and their changes in middle-aged and elderly adults from a national cohort.

METHODS

A longitudinal cohort study was conducted with a total of 17,708 individuals from 150 urban communities and 450 rural villages in 28 provinces in China.

RESULTS

After making exclusions, 11,492 and 8604 participants were included for incident asthma and incident depressive symptoms analysis, respectively. The incidence density was 4.46 and 10.24 for every 1000 person-years, respectively. Baseline depressive symptoms were associated with a higher risk of incident asthma (Hazard ratio [HR] = 1.60, 95 % confidence interval [CI]: 1.27, 2.02). Decreased depressive symptoms during baseline or follow-ups or both baseline and follow-ups were associated with a lower risk of incident asthma (P_{for trend} < 0.0001). Every 1-score increment of CES-D score was associated with a 4 % increase in asthma, with a non-linear association (P = 0.04) between CES-D score (break point = 7) and asthma. Asthma status increased the risk of participants with severe depressive symptoms (HR = 1.51, 95 % CI: 1.19, 1.92), especially in males (P_{for interaction} = 0.02).

LIMITATIONS

Depressive symptoms and asthma were assessed by validated questionnaires instead of clinical diagnosis.

CONCLUSIONS

Bi-directional associations between asthma and depressive symptoms do exist. Effective measures should be taken to reduce depressive symptoms and the risk of incident asthma in middle aged and elderly adults in China.

Caregiver Depressive Symptoms and Primary Medication Nonadherence in Children With Asthma

INTRODUCTION

The purpose of this study was to identify risk factors for primary medication nonadherence among low-income minority children with persistent asthma.

METHOD

Data were from an environmental control and educational intervention for children with uncontrolled asthma who were treated in the emergency department for an asthma exacerbation. Presence or absence of pharmacy records for child asthma medications was the outcome of interest. A range of sociodemographic, health, and psychosocial measures were included in the binary logistic regression.

RESULTS

Of the 222 youths (mean age = 6.3 years; 93.7% Black), 25 (11.3%) lacked pharmacy records of asthma medications. For every 1-point increase in caregiver depressive symptoms, the odds of the child having a pharmacy record declined by 5% (odds ratio = 0.95; p = .012).

DISCUSSION

Providers should systematically assess and monitor caregiver depressive symptoms as a potential contributing factor for primary medication nonadherence in low-income minority children with persistent, uncontrolled asthma.

The Effects of Caregiver Social Support and Depressive Symptoms on Child Medication Adherence and Asthma Control

The purpose of this study was to examine relationships among caregiver social support, caregiver depressive symptoms, medication adherence, and asthma control in a sample of low-income, urban, Black children aged 3–12 years with uncontrolled asthma and their caregivers. Using longitudinal data from a randomized controlled trial (RCT) assessing the efficacy of an environmental control educational intervention, we used generalized estimating equations and ordered logistic regression models to evaluate the relationship between caregiver social support (Medical Outcomes Study Social Support Survey), depressive symptoms (Center for Epidemiologic Studies Depression scale), and two child asthma outcomes: (a) medication adherence (Asthma Medication Ratio) and (b) asthma control. At baseline, 45.7% of the 208 children had very poorly controlled asthma. Nearly a third of caregivers (97% female) had clinically significant depressive symptoms at each data collection point. Social support was not associated with either asthma outcome nor did it moderate the relationship between depressive symptoms and child asthma outcomes. Higher caregiver depressive symptoms predicted decreased medication adherence (b=−0.003, SE 0.002). Moderate asthma at baseline (OR: 0.305, SE: 0.251), severe asthma at baseline (OR: 0.142, SE: 0.299), household income < $20,000 per year (OR: 0.505, SE: 0.333), and fall season (OR: 0.643, SE: 0.215) were associated with poorer asthma control. Attending to the social context of low-income, urban, Black children with asthma is critical to reduce asthma morbidity. Maternal depressive symptoms are modifiable and should be targeted in interventions to improve child asthma outcomes in this vulnerable population. The RCT was registered with ClinicalTrials.gov (NCT01981564) in October 2013.

Cockroach exposure and perceived stress interact to predict clinical outcomes in childhood asthma

Background

Nonpharmacologic interventions for asthma management rely on identification and mitigation of important asthma triggers. Cockroach exposure is strongly associated with asthma morbidity. It is also associated with stress, another risk factor for asthma. Despite high prevalence of both in vulnerable populations, the impact of joint exposure has not been examined.

Methods

Participants included 173 children with asthma in New Orleans, Louisiana. Cockroach exposure was based on visual inspection using standard protocols. Caregiver stress was measured using Cohen’s 4-item Perceived Stress Scale. Outcomes included unscheduled clinic or emergency department (ED) visits, hospitalization, and pulmonary function. Multivariable logistic regression was performed to assess independent effects of the exposure on the outcome and effect modification was examined in stratified analysis based on stress. Path analysis to explore the mediation effect by stress was performed using a probit link with parameters based on Bayes’ method with non-informative priors.

Results

Adjusting for stress and other covariates, cockroach exposure was associated with unscheduled clinic/ED visits (aOR = 6.2; 95% CI 1.8, 21.7). Positive associations were also found for hospitalization and FEV₁ < 80%. High stress modified the relationship with unscheduled clinic/ED visits (high aOR = 7.7 95% CI 1.0, 60.2, versus normal aOR = 4.1 95% CI 0.8, 21.9). Path models identified direct and indirect effects (p = 0.05) indicating that a majority of the total effect on unscheduled clinic/ED visits is attributed directly to cockroach exposure.

Conclusion

The strong association between cockroach exposure and asthma morbidity is not due to uncontrolled confounding by stress. The combination of cockroach exposure and high stress, common in urban homes, are modifiable factors associated with poor asthma outcomes.

Childhood Allergies: The Role of Maternal Depression and Anxiety, and Family Strain

Maternal mental disorder and a negative family emotional climate are a great source of stress for many children, yet their role in the childhood development or expression of asthma and allergies remains poorly understood, particularly beyond the first 1–2 years of life. The current study tested whether childhood allergy onset and symptomatology would be predicted by (1) perinatal and any time exposure to maternal depression or anxiety and (2) current family emotional strain (whole family, mother-child). UK mothers of children aged 2–12 years (N = 328) living with them completed an online survey of measures. Children exposed to maternal depression were almost twice as likely to be diagnosed and almost five times as likely to screen positive for an allergic disorder. Perinatal depression was linked to childhood allergies, but more moderately. Any anxiety exposure, and not specific to the perinatal period, predicted allergy status. Family emotional strain contributed independently to variance in concurrent child allergic symptomatology. All results were independent of potential confounders and current mental distress. The findings highlight the importance of maternal mental health and family function in the child’s neuro-immune development, and that these factors need to be addressed in the treatment of childhood allergic disorders.

Participant-level characteristics differ by recruitment setting when evaluating a behavioral intervention targeting adolescents with asthma

OBJECTIVE

The recruitment setting plays a key role in the evaluation of behavioral interventions. We evaluated a behavioral intervention for urban adolescents with asthma in three randomized trials conducted separately in three different settings over the course of 8 years. We hypothesized that characteristics of trial participants recruited from the ED and clinic settings would be significantly different from that of youth participating in the school-based trials. The intervention evaluated was Puff City, a web-based program that uses tailoring to improve asthma management behaviors.

METHODS

The present analysis includes youth aged 13-19 years who reported a physician diagnosis of asthma and symptoms at trial baseline. In the three trials, all participants were randomized post-baseline to a web-based, tailored intervention (treatment) or generic web-based asthma education (control).

RESULTS

Compared to school-based trial participants, ED participants had significantly more acute-care visits for asthma (p < 0.001) and more caregiver depression (p < 0.001). Clinic-based participants were more likely to have computer/ internet access than participants from the school-based trial (p < 0.001). Both ED and clinic participants were more likely to report controller medication (p's < 0.001) and higher teen emotional support (p's < 0.01) when compared to the schools, but were less likely to report Medicaid (p's < 0.014) and exposure to environmental tobacco smoke (p < 0.001).

CONCLUSION

Compared to participants in the school-based trials, participants recruited from ED and clinic settings differed significantly in terms of healthcare use, as well as psychosocial and sociodemographic factors. These factors can inform intervention content, and may impact external validity of behavioral interventions for asthma.

The Critical Need to Recognize That Families Matter for Adult Health: A Systematic Review of the Literature

A systemic approach to researching families and health should capture the complex network within which family members are embedded, including multiple family relationships and larger systems of health care. However, much of the families and health research focused on adult family members has focused solely on intimate partnerships, usually the marital relationship. This neglects the remainder of the powerfully influencing family relationships adults retain, and may increasingly focus on as they age. We conducted a systematic review of the families and adult health literature, retaining 72 articles which were subsequently thematically coded to highlight main foci of this area of research. Results highlight six themes, which include family relationship quality, family composition, behavioral factors in health and health care, psychophysiological mediators, caregiving, and aging health. Findings support an underrepresentation of family members, other than the intimate partner, in research on adult health.

Money matters: a multicenter cross-sectional study of depressive symptoms among the caregivers of children on peritoneal dialysis in Mainland China

Background

The caregivers of children on peritoneal dialysis face heavy care burdens and may have a high risk of depression. This study aimed to describe the prevalence and severity of depression and identify its related demographic and socioeconomic factors in the caregivers of children on peritoneal dialysis in China.

Methods

A multicenter cross-sectional study was conducted in four pediatric dialysis centers in four tertiary children’s hospitals in mainland China. Primary caregivers of children with end-stage kidney disease and currently on peritoneal dialysis were screened and recruited from December 2018 to July 2019. A self-developed questionnaire and the Self-Rating Depression Scale (SDS) were administered to the participants by a trained nurse in each center. The chi-square test or Fisher’s exact test, one-way ANOVA, and the Mann-Whitney U test were used to compare the prevalence of depressive symptoms by demographic features. A multivariate logistic regression analysis was used to identify factors related to depressive symptoms in caregivers of children on peritoneal dialysis.

Results

One hundred twenty-one caregivers were included in the data analysis. The mean age of the caregivers was 40.1 ± 8.1 years. More than 75% of the participants were female, married, and unemployed. The overall prevalence of depressive symptoms was 59%. In total, 46 (38%), 20 (17%) and 5 (4%) caregivers reported mild, moderate, and severe depressive symptoms, respectively. In the univariate analysis, caregivers with an average household income per month under 4000 RMB and caregivers of children undergoing laparoscopic surgery had a higher prevalence of depressive symptoms. Characteristics such as treatment center, duration on PD, PD modalities, and history of peritonitis episodes showed no difference in terms of the prevalence of depressive symptoms. The multivariate logistic regression analysis demonstrated that an average household income per month under 4000 RMB was the associated factor for caregivers’ depressive symptoms.

Conclusions

The caregivers of children on peritoneal dialysis in mainland China were socially vulnerable and experienced depression. Those who had a higher average household income were less vulnerable to depression.

Maternal Depressive Symptoms, Lung Function, and Severe Asthma Exacerbations in Puerto Rican Children

BACKGROUND

Maternal depression has been linked to health care use for asthma in cross-sectional or short-term follow-up studies of school-aged children.

OBJECTIVE

To examine whether increased or persistent maternal depressive symptoms over approximately 5 years are associated with severe asthma exacerbations or worse lung function in youth.

METHODS

A prospective study of 386 youth living in Puerto Rico, aged 6 to 14 years at a baseline visit and 9 to 20 years at a second visit, was performed. Our exposure of interest was change in persistence of maternal depressive symptoms, assessed at both visits using the Center for Epidemiologic Studies Depression Scale (CESD). Our outcomes of interest were change in percent predicted forced expiratory volume in 1 second (FEV₁) and FEV₁/forced vital capacity (FVC) between the first and second visits in all subjects, and ≥1 severe asthma exacerbation in the year before the second visit in subjects with asthma.

RESULTS

In a multivariable analysis, each 1-point increment in the CESD score was associated with decrements of 0.15% in percent predicted FEV₁ (95% confidence interval [CI] = -0.28% to -0.01%; P = .03) and 0.10% in percent predicted FEV₁/FVC (95% CI = -0.20% to 0.001%; P = .05) between visits, as well as with 1.03 times increased odds of ≥1 severe asthma exacerbation at the second visit (95% CI for odds ratio = 0.99 to 1.06, P = .09). In a multivariable analysis, the presence of maternal depressive symptoms (a CESD score ≥21 points) at the second visit or at both visits was significantly associated with 3.17 to 3.52 times increased odds of ≥1 severe asthma exacerbation in the year before the second visit.

CONCLUSIONS

Increasing or persistent maternal depressive symptoms over approximately 5 years are associated with worse lung function measures and severe asthma exacerbations among Puerto Rican youth, a high-risk population.

Maternal common mental disorder over time and asthma control: The role of social support

BACKGROUND

Despite therapeutic advances, asthma prevalence remains high. Psychosocial factors, including maternal mental disorders, may be involved. This study aims to evaluate the association of maternal common mental disorders (CMDs) and their change over time with asthma morbidity in the child and to observe the effect of social support on this association.

METHODS

This prospective study involved 189 dyads of mothers and their asthmatic children aged between 2 and 14 years, assisted in specialized outpatient clinics. We measured the association of maternal CMD evolution (absent, maintained, or improved over time) with asthma control and visits to the emergency department (ED) due to asthma attacks through Poisson regression analysis. We further stratified the sample according to social support levels to identify a possible effect of this variable on the association of maternal psychological symptoms with asthma morbidity.

RESULTS

Compared with mothers who maintained CMD over time, maternal CMD absence had a protective effect on the occurrence of visits to the ED (RR: 0.45; 95% CI: 0.26-0.79) and maternal CMD improvement was associated with lower risk of uncontrolled asthma in the child (RR: 0.60; 95% CI: 0.37-0.97). There was a stronger association of maternal CMD improvement with asthma control in the child only for the stratum of mothers with high social support in its three dimensions (affective-social interaction, emotional-informational, and material dimensions).

CONCLUSIONS

Maternal CMD absence and improvement over the study period were protective factors for uncontrolled asthma in the child, mainly in the presence of high social support.

The role of parental psychological flexibility in childhood asthma management: An analysis of cross-lagged panel models

OBJECTIVE

This is a secondary analysis of a previously reported randomized controlled trial, aimed at examining the mediating role of parental psychological flexibility (PF) in an Acceptance and Commitment Therapy (ACT)-based childhood asthma management program for parents.

METHODS

The participants were 168 parents (mean age (SD) = 38.40 (5.90) years; 88.1% mothers) and their children who had been diagnosed with asthma (mean age (SD) = 6.81 (2.50) years; 62% boys). They were randomly allocated to either the program composed of a four-session, group-based ACT plus asthma education (ACT Group) or to a group-based asthma education talk plus three telephone follow-ups (Control Group). The parents underwent assessments at baseline, and immediately, 3-months, and 6-months after the intervention for the following outcomes: PF (Acceptance and Action Questionnaire-II), psychological distress of the parents (Depression Anxiety Stress Scale-21); and the asthma symptoms and use of inhaled bronchodilators of their children.

RESULTS

Cross-lagged panel models showed that the improvement in parental PF at post-intervention mediated the effect of ACT on reducing parental psychological distress (all beta coefficients (βs) ranged from -2.20 to - 2.30, all Ps < 0.01) and childhood asthma symptoms in terms of daytime symptoms (β = -0.22, 95% CI [-0.52, -0.02], P = 0.04), nighttime symptoms (β = -0.17, 95% CI [-0.33, -0.02], P = 0.04), and the use of bronchodilators (β = -0.22, 95% CI [-0.48, -0.02], P = 0.03) at 6-months post-intervention.

CONCLUSION

ACT makes a unique contribution to improving the health outcomes of parents and their children diagnosed with asthma through fostering parental PF.

Chronic stress and asthma in adolescents

OBJECTIVE

First, to review and critically discuss published evidence on psychosocial stressors, stress, and asthma in adolescents and, then, discuss potential future directions in this field.

DATA SOURCES

The data source is the National Library of Medicine (PubMed database).

STUDY SELECTIONS

A literature search was conducted for human studies on stressors or stress and asthma between 2000 and 2020. Studies that were published in English, contained a full text, and included adolescents were considered for inclusion in this review.

RESULTS

Compared with the available body of evidence in children and adults, relatively few studies have been published in adolescents. Current evidence suggests that exposure to stressors (at the individual, family, and community levels) or stress (acute and chronic) is associated with asthma and worse asthma outcomes, but such evidence must be cautiously interpreted owing to limitations in the design or the analytical approach of the published studies.

CONCLUSION

Future large studies with a prospective design should determine whether and how stressors or stress causes or worsens asthma in adolescents. At present, clinicians should assess exposure to stressors (eg, violence or abuse) and screen for anxiety and depressive disorders when caring for adolescents with asthma in addition to providing referrals to social workers or mental health professionals when appropriate. Public health policies are needed to reduce psychosocial stressors, such as gun violence and racism, in adolescents.

Early childhood risk exposures and inflammation in early adolescence

There is now reliable evidence that early psychosocial stress exposures are associated with behavioral health in children; the degree to which these same kinds of stress exposures predict physical health outcomes is not yet clear. We investigated the links between economic adversity, family and caregiving stress in early childhood and several markers of immune function in early adolescence. The sample is derived from the Family Life Project, a prospective longitudinal study of at-risk families. Socio-demographic and psychosocial risks have been assessed at regular intervals since the children were first assessed at 2 months of age. When the children were early adolescents, we conducted an in-depth health assessment of a subsample of families; blood samples were collected from venipuncture for interleukin(IL)-6, Tumor Necrosis Factor (TNF)-alpha, and C-reactive protein (CRP), as well as glucocorticoid resistance. Results indicated limited but reliable evidence of an association between early risk exposure and inflammation in adolescence. Specifically, caregiver depressive symptoms in early childhood predicted elevated CRP almost a decade later, and the prediction was significant after accounting for multiple covariates such as socio-economic adversity, health behaviors and body mass index. Our findings provide strong but limited evidence that early stress exposures may be associated with inflammation, suggesting one mechanism linking early stress exposure to compromised behavioral and somatic health.

Exploring a broader context of the home environment and its relationship with asthma control in American Indian children

In this cross-sectional study of 60 American Indian mother-child dyads from Southeastern North Carolina, we examined whether childhood asthma control was related to household-level factors, such as environmental tobacco smoke and family management behaviors. We also examined the relationships among family management behaviors and maternal depressive symptoms. We used logistic regression to assess the relationships among childhood asthma control, the presence of environmental tobacco smoke, and family management behaviors, specifically condition management ability (CMA) and condition management effort (CME). We used linear regression to evaluate the relationships between both CMA and CME and maternal depressive symptoms. Better asthma control in children was associated with the absence of environmental tobacco smoke in the home and the maternal perception of asthma as a manageable condition. Mothers perceived an increase in effort to manage their child's asthma as their depressive symptoms increased. These findings emphasize the importance of environmental triggers, perceptions of condition management, and maternal mental health in controlling asthma in American Indian children. Interventions to reduce environmental triggers, treat maternal depressive symptoms, and support mothers in their ability to manage childhood asthma may yield better asthma control and help to reduce existing racial disparities in this population.

Association between family management and asthma control in children with asthma

PURPOSE

The purpose of this study is to investigate the association between family management and asthma control in children with asthma.

DESIGN AND METHODS

This cross-sectional descriptive study recruited 142 children with asthma and their parents. We used the Family Management Measure (FaMM), the Childhood Asthma Control Test (C-ACT), and fractional exhaled nitric oxide (FeNO) detectors to assess family management and asthma control. The McNemar's test was used to determine the proportional difference between C-ACT and FeNO in evaluating asthma control. Pearson correlation analysis and multiple linear regression analysis were used to assess the relationship between family management and asthma control in children with asthma.

RESULTS

There was no significant difference in the proportion of C-ACT and FeNO in evaluating asthma control (McNemar's test p = .593). Child's Daily Life, Condition Management Ability, and Parental Mutuality were positively correlated with C-ACT (r = 0.398 to 0.655; all p < .05) and negatively correlated with FeNO (r = -0.245 to -0.402; all p < .05); Condition Management Effort, Family Life Difficulty, and View of Condition Impact were negatively correlated with C-ACT (r = -0.416 to -0.672; all p < .05) and positively with FeNO (r = 0.248 to 0.427; all p < 0.05). Child's Daily Life, Condition Management Effort, and View of Condition Impact dimensions significantly predicted the C-ACT results, and the Condition Management Effort and View of Condition Impact dimensions significantly predicted the FeNO results (p < .05).

PRACTICAL IMPLICATIONS

Pediatric nurses could provide family management education for parents to improve asthma control in children. In addition, pediatric nurses might assess asthma control condition of asthmatic children in combination with C-ACT and FeNO levels.

Targeting cell signaling in allergic asthma

Asthma is chronic inflammation of the airways characterized by airway hyper-responsiveness, wheezing, cough, and dyspnea. Asthma affects >350 million people worldwide. The Th2 immune response is a major contributor to the pathophysiology of asthma. Targeted therapy modulating cell signaling pathways can be a powerful strategy to design new drugs to treat asthma. The potential molecular pathways that can be targeted include IL-4-IL-13-JAK-STAT-MAP kinases, adiponectin-iNOS-NF-κB, PGD2-CRTH2, IFNs-RIG, Wnt/β-catenin-FAM13A, FOXC1-miR-PI3K/AKT, JNK-Gal-7, Nrf2-ROS, Foxp3-RORγt, CysLTR, AMP, Fas-FasL, PTHrP/PPARγ, PAI-1, FcɛRI-LAT-SLP-76, Tim-3-Gal-9, TLRs-MyD88, PAR2, and Keap1/Nrf2/ARE. Therapeutic drugs can be designed to target one or more of these pathways to treat asthma.
