Experiences of parents of teenagers with life-threatening food allergies: a qualitative systematic review protocol

OBJECTIVE

The objective of this review is to synthesize the experiences of parents of teenagers with life-threatening food allergies.

INTRODUCTION

Life-threatening food allergies are increasing globally, with a significant effect on families, particularly parents. The teenage years are a time of increasing autonomy for young people; however, for parents living with and caring for a teenager with a life-threatening food allergy, this responsibility can have a considerable impact.

INCLUSION CRITERIA

This review will include qualitative studies on the experiences of parents of teenagers with life-threatening food allergies, including, but not limited to, caregiving, parenting, and psychosocial experiences; any day-to-day activities, happenings, thoughts, or feelings related to parenting a teenager with life-threatening food allergies; and the handing over of responsibility for the allergy to the teenager. The review will include studies on participants in the community and in health care settings such as inpatient hospitalizations, outpatient visits, school and sports events, family dinners, restaurants, and travel. Participants from all cultural backgrounds, socio-economic backgrounds, and countries will be included.

METHODS

The review will follow the JBI methodology for systematic reviews of qualitative evidence. The search for published studies will include CINAHL, MEDLINE, and PsycINFO (EBSCOhost); Embase (Ovid); LILACS, IBSS, and Sociological Abstracts (ProQuest). The search for unpublished studies will include ProQuest Dissertations and Theses, Open Access Theses and Dissertations (OATD), Bielefeld Academic Search Engine (BASE), Google, and Google Scholar. Databases will be searched from inception until the present. JBI tools and guidelines will be used to conduct critical appraisal, data extraction, data synthesis, and assessment of confidence in the findings.

Provision of Food Allergy Care in the United Kingdom and United States: Current Issues and Future Directions

Food allergy (FA) is a growing issue worldwide. The United Kingdom and United States are high-income, industrialized countries with reported increases in FA prevalence over the past few decades. This review compares delivery of FA care in the United Kingdom and United States and each country's response to the heightened demand and disparities for FA services. In the United Kingdom, allergy specialists are scarce and general practitioners (GPs) provide most allergy care. Whereas the United States has more allergists per capita than the United Kingdom, there is still a shortage of allergy services owing to the greater reliance on specialist care for FA in America and wide geographic variation in access to allergist services. Currently, generalists in these countries lack the specialty training and equipment to diagnose and manage FA optimally. Moving forward, the United Kingdom aims to enhance training for GPs so they may provide better quality frontline allergy care. In addition, the United Kingdom is implementing a new tier of semi-specialized GPs and increasing cross-center collaboration through clinical networks. The United Kingdom and United States aim to increase the number of FA specialists, which is critical at a time of rapidly expanding management options for allergic and immunologic diseases requiring clinical expertise and shared decision-making to select appropriate therapies. While these countries aim to grow their supply of quality FA services actively, further efforts to build clinical networks and perhaps recruit international medical graduates and expand telehealth services are necessary to reduce disparities in access to care. For the United Kingdom in particular, increasing quality services will require additional support from the leadership of the centralized National Health Service, which remains challenging.

App providing psychosocial and educational supports benefits caregivers of children with newly diagnosed food allergies

Background

Approximately 6 million children in the United States have a diagnosed food allergy, and 32% of caregivers experience significant psychological distress due to the diagnosis. Despite substantial impacts on psychosocial health and quality of life, few interventions aim to help caregivers of newly diagnosed children. There is a clear, unmet need for interventions to address caregiver distress, especially after the initial diagnosis.

Objective

We developed a mobile psychosocial health intervention, the Food Allergy Symptom Self-Management with Technology (FASST) app. Primary end points were to determine the app's feasibility and caregiver satisfaction.

Methods

This was a phase II, randomized controlled, implementation study (4-week duration) in caregivers (N = 30) of children ≤ 18 years of age who were newly diagnosed with a food allergy (≤90 days after the diagnosis). Caregivers (n = 20) were randomized to use the FASST app (intervention group) with access to individualized, self-help symptom relief interventions and food allergy support, and educational resources; or to use a limited app with a basic FASST interface and links to a few educational resources (control group [n = 10]). Ten participants (intervention group, n = 5; control group, n = 5) participated in semistructured interviews at week 4.

Results

Both groups found the app relatively easy to use. The intervention group scores for safety preparedness during social activities increased by 24%, whereas those in the control group experienced a 1% decline. The intervention group participants increased the use of websites to find food allergy information by 17% at week 4 compared with 4% for the control group. Although the intervention group participants showed greater gains than did those in the control group in their confidence to prepare for and prevent allergic reactions, and greater declines in perceived social limitations, more participants in the control group endorsed confidence in their ability to recognize (11% versus 5%, respectively) and treat (10% versus 6%, respectively) allergic reactions.

Conclusion

Analysis of our results suggests that the FASST app may provide a feasible means of delivering psychosocial and educational supports to caregivers of children recently diagnosed with a food allergy.Clinical trial NCT04512924, www.clinicaltrials.gov.

Posttraumatic stress and medication adherence in pediatric transplant recipients

Adolescent transplant recipients may encounter a range of potentially traumatic events (PTEs) pre- and posttransplant, yet little is known about the relationship between posttraumatic stress symptoms (PTSS) and medication adherence in this population. In the present study, adolescent recipients and caregivers completed psychosocial questionnaires at enrollment. Outpatient tacrolimus trough level data were collected over 1 year to calculate the Medication Level Variability Index (MLVI), a measure of medication adherence. Nonadherence (MLVI ≥2) was identified in 34.8% of patients, and most (80.7%) reported ≥1 PTE exposure. Levels of PTSS indicating likely posttraumatic stress disorder (PTSD) were endorsed by 9.2% of patients and 43.7% of caregivers. PTSS and MLVI were significantly correlated in the liver subgroup (r = .30, p = .04). Hierarchical multivariable linear regression analyses revealed overall patient PTSS were significantly associated with QoL (p < .001). PTEs are common in adolescent recipients; a minority may meet criteria for PTSD. PTSS screening to identify nonadherence risk requires further investigation and addressing PTSS may improve QoL. Caregivers appear at greater risk for PTSD and may require their own supports. The study was approved by each participating center's Institutional Review Board.

Food-allergy-specific anxiety and distress in parents of children with food allergy: A systematic review

BACKGROUND

Parenting a child with food allergy (FA) can lead to impaired quality of life and family functioning. Anxiety is a critical component of FA-associated distress and a potential target for therapeutic intervention. This systematic review aimed to clarify the concept of FA-specific anxiety (FAA) and its antecedents, consequences, and correlates and to determine the extent to which existing FA-specific outcome measures capture symptoms of parental distress and FAA.

METHODS

MEDLINE, EMBASE, PsycINFO, and CENTRAL were searched for qualitative and quantitative studies examining distress or anxiety in parents of children with FA through August 2020. This review was registered with PROSPERO (CRD42020208316) and conducted in accordance with PRISMA guidelines.

RESULTS

Ninety-eight studies were included in the final narrative synthesis. Most participants were mothers, and reporting of demographic data was limited. Parents identified anxiety as the most burdensome form of FA-specific emotional distress. Several allergy-related factors as well as medical and psychosocial interventions were associated with reduced parental anxiety and distress. However, affective, cognitive, and behavioral dimensions of FAA were only partially addressed by existing measures for general anxiety symptoms and FA-specific parental factors.

CONCLUSIONS

FAA contributes to distress and functional impairment among parents of children with FA. Current FA-specific parent measures fail to adequately capture dimensions of FAA, suggesting that further work is needed to improve the assessment and monitoring of FAA and its impacts. Characterization of this construct represents an initial step in developing standardized methods for assessing and monitoring FAA in clinical populations.

Food Allergy Symptom Self-Management With Technology (FASST) mHealth Intervention to Address Psychosocial Outcomes in Caregivers of Children With Newly Diagnosed Food Allergy: Protocol for a Pilot Randomized Controlled Trial

Background

Approximately 2.4 million children in the United States suffer from food-induced anaphylaxis, a condition that is annually responsible for over 200 deaths and 200,000 emergency room visits. As a result, caregivers of children newly diagnosed with severe and life-threatening food allergic reactions experience clinically significant symptoms of psychological distress, including fatigue, anxiety, depressed mood, social isolation, and substantially reduced quality of life. Despite this recognition, there is a lack of caregiver-centered self-management interventions to address these concerns.

Objective

In this protocol, we propose to develop and conduct feasibility testing of a technology-enhanced, self-management, mobile health, smartphone app intervention called Food Allergy Symptom Self-Management with Technology for Caregivers (FASST) designed to meet the psychosocial health needs of caregivers of children with a new diagnosis of food allergy.

Methods

This pilot study uses qualitative work (Phase I) to inform a 4-week longitudinal randomized controlled trial (Phase II). In Phase I, 10 caregivers of children (≤18 years old) with established food allergy (≥1 year from diagnosis) will participate in semistructured interviews to inform the development of the FASST app. In Phase II, 30 caregivers of children (≤18 years old) with a newly diagnosed food allergy (≤90 days from diagnosis) will be randomized 2:1 to receive the FASST intervention (n=20) or control condition (basic app with educational resources; n=10). Process measures include feasibility, caregiver acceptability, adherence, and satisfaction. Outcome measures include caregiver fatigue, anxiety, depression, sleep, self-efficacy, and quality of life measured at baseline, week 4, and 3 months post study completion.

Results

Phase I study activities have been completed, and Phase II participant enrollment into the randomized controlled trial is expected to commence in 2021.

Conclusions

With limited readily available resources at their disposal, the results from this study have the potential to provide caregivers of children with a newly diagnosed food allergy a tool to help them self-manage and mitigate negative psychosocial factors during a critical time period in the caregiving/condition trajectory.

A Study of Dietary and BMI Changes Over Time in Mothers of Children with Food Allergies

Few follow-up surveys have been conducted with regard to the changes in diet of mothers of children with food allergy. We examined changes in food and BMI over time in the mothers of children with food allergies. A total of 146 mothers completed a diet survey twice, with the first conducted in 2013-2016 and the second in 2018, and the dietary changes were examined. Furthermore, among the 120 mothers who eliminated eggs from their diet in the first survey, 98 continued to eliminate eggs and 22 reintroduced eggs during the second survey, and the change over time was examined. Additionally, factors related to BMI were analyzed. We observed a change in the amount of egg intake over time within each group. As the number of children who consumed eggs as the causative food declined, the amount of eggs consumed by the concerned mothers significantly increased (median: 7.8 g/1,000 kcal→12.7 g/1,000 kcal) (p<0.01), even in children who continued to not consume eggs. We found a negative correlation between BMI in mothers of children with FA and vegetable protein. The mothers indicated that their awareness on food allergy improved, which we believe led to increased consumption of foods that had been restricted thus far. BMI was believed to be related to synchronization with the elimination-substitution diet.

Qualitative analysis of perceived impacts on childhood food allergy on caregiver mental health and lifestyle

BACKGROUND

Approximately 8% of children have food allergy. Yet, little is known about how parents cope with the burden of this disease.

OBJECTIVE

This study aimed to describe the perceptions of food allergy-related mental health issues of parents of children with food allergy.

METHODS

Parents of children with pediatric allergist-diagnosed food allergy were recruited through allergy clinics and education centers in a large Canadian city. We used content analysis to identify overarching themes.

RESULTS

We interviewed 21 parents with children (boys [13/21; 62.9%]) aged younger than 12 months to 16 years. Interviews averaged 47 (range 33-82) minutes. Most children were diagnosed as infants, and few (7/21; 33.3%) were monoallergic. About one-half (7/16; 43.8%) had a history of anaphylaxis. Parents of children with a single food allergy spoke of "accommodation and adaptation." In contrast, parents of children with multiple food allergies described "anxiety and isolation" and spoke of being "depressed" and "terrified" about leaving their children in the care of others who may not be equipped to handle food allergy. Many parents felt "overwhelmed and alone," especially if they lacked support from extended family and/or their social circle. "Fear for today, fear for the future" was commonly described by parents, although a tenuous symbiotic coexistence was developed, with parents stating "Food allergy management has become our normal." Finally, a small group of parents reported that "Bullying happens, but we are alone to cope with it."

CONCLUSION

Multiple food allergies negatively affect the mental health of parents, in a variety of well-being domains.

The impact of caregiver post-traumatic stress and depressive symptoms on pediatric transplant outcomes

PTSS as well as symptoms of depression have been reported in children who experience a serious medical adversity as well as their caretakers. The adverse effects of PTSS, when experienced by the patients, on medical outcomes have been clearly documented. However, the impact of those symptoms, if any, when experienced by the caretakers on child outcomes has not been investigated prospectively. We evaluated whether caregiver PTSS and depression symptoms predict adherence to medications and medical outcomes in a prospective multisite study. Four hundred children participated in MALT. Caretaker PTSS were assessed by the IES and depressive symptoms by CES-D. During 2 years of follow-up, the MLVI was used to determine adherence. Centrally read, biopsy-confirmed organ rejection was the primary medical outcome. IES scores were not associated with either adherence or rejection outcomes. In contrast, there were significant correlations between CES-D (depression) scores and lower adherence, r = .13, P < .001, and a trend toward higher scores on the CES-D among those whose children had experienced rejection, 12.4 (SD = 10.9) versus 9.1 (SD = 8.6), P = .077. Caregivers' PTSS were not a risk factor for poor child outcomes in this cohort, whereas depression symptoms were associated with non-adherence and possibly increased rates of rejection. Further study can validate if caregivers' depression as opposed to PTSS confers greater risk and should be a focus during the clinical care of medically ill children.

Pediatric food allergy-related household costs are influenced by age, but not disease severity

Objective

The economic burden of food allergy on households is poorly understood. We evaluated the household costs associated with specialist-diagnosed pediatric food allergy, with focus on age and disease severity.

Study design

A cross-sectional study of 70 Swedish case-control pairs (59% boys) was conducted using Food Allergy Economic questionnaire. Household costs were analyzed between age- and gender-matched cases (children aged 0–17 years, with specialist-diagnosed food allergy) and controls (non-food allergic households).

Results

Parents were predominantly university-educated and employed full-time. Most cases had parent-reported previous anaphylaxis. Mean total annual household costs were comparable between cases and controls. However, compared to controls, cases had significantly higher direct medical-, and non-medical related costs; higher indirect medical-related costs, and higher intangible costs (all p < 0.05). In a sensitivity analyses of only cases aged 0–12 years, direct household costs, including lost earnings due to child's hospitalization, were significantly higher than controls. Results from only children with severe disease paralleled those of all cases vs. controls.

Conclusions

Although pediatric food allergy is not associated with higher total annual household costs, these households have significantly higher direct medical-related, indirect and intangible costs vs. non-food allergic households. Higher household costs were identified amongst younger children, but not disease severity.

Beyond Avoidance: the Psychosocial Impact of Food Allergies

Over the past few years, the rates of food allergies have dramatically increased. As a result, the lives of patients and their caregivers have been dramatically altered. While most attention surrounding food allergies has focused on treatment, less consideration has been given to the mental health ramifications of living with this condition, among them depression, anxiety, post-traumatic stress, being bullied, and an overall poorer quality of life. At the same time, patients' family lives are often disrupted. Parents of food-allergic children, especially mothers, report anxiety, depression, and a decreased quality of life. Indeed, mental health issues associated with food allergies are likely underrecognized. In this review, we describe not only the psychosocial impacts of food allergies but also survey treatments that can be used to address this burgeoning problem. Interventions include educating members of the greater community about food allergies, camps for food allergic children, and support groups for parents. For physicians, treatment options consist of oral challenges, proximity challenges, oral immunotherapy, and cognitive behavioral therapy. Although the existing research is built on an already strong foundation, ultimately more studies are needed to deepen our understanding of the relationship between food allergies and mental health.

Student and Parent Perspectives on Severe Food Allergies at College

INTRODUCTION

Constant vigilance to manage severe food allergies (FAs) can lead to high stress. Additional stress may develop during life-course transitions, such as the transition to college. However, few studies have evaluated everyday and FA-related stress in college students with FA and their parents. This analysis examined experiences of 26 college students with FA and their parents.

METHODS

Students and parents completed online surveys in a mixed-methods exploratory study of everyday and FA-related stressors, potential contributing factors, and FA management.

RESULTS

FA affected nearly all areas of students' lives. Management required constant vigilance because of issues of trust in others. However, nearly 40% of students did not consistently carry emergency medication to counteract reactions. Parents worried from a distance while learning to trust their child's FA management capabilities.

DISCUSSION

Additional preparation and support for college students with severe FA and their parents may help improve stress and FA management.

Integrated behavioral health care for management of stress in allergic diseases

OBJECTIVE

This article reviews current findings regarding the management of stress in allergic disease.

DATA SOURCES

The authors use articles and books published between 1995 and 2017. Approximately 85% of sources used were published in the last 10 years, and 60% were published in the last 5 years. Most of the sources are peer-reviewed articles.

STUDY SELECTIONS

Articles that focused on allergic diseases such as allergic rhinitis, food allergies, urticaria, and allergic asthma were included. Articles in which whether the underlying disorder was allergic in nature (for example, nonspecified asthma) were not included. Preference was given to articles published within the past five years.

RESULTS

Patients with allergic diseases, particularly those with chronic or co-occurring allergic diseases, often experience stress and, in turn, this experience of stress can exacerbate disease presentation. High rates of treatment nonadherence in patients with allergic disease also can increase disease burden and stress. Research supports the benefit of behavioral health interventions for patients with allergic disease. Interventions with multidisciplinary teams, which include behavioral health, as well as interventions at the school, workplace, and community level, are recommended.

CONCLUSION

Medical providers working with patients with allergic disease need to address patients' experience of stress and nonadherence to treatment recommendations. This could be done through routine screening and referrals to behavioral health or, ideally, through incorporation of a behavioral health provider within a multidisciplinary patient team.

Patterns of adaptation to children's food allergies

BACKGROUND

Families with food allergy (FA) are at risk of reduced quality of life and elevated anxiety. A moderate level of anxiety may be beneficial to sustain vigilance for food avoidance; however, excessive anxiety may increase risk for burden and maladjustment. The current study presents a framework for understanding the patterns of adaptation to FA across families and to identify typologies of families that would benefit from intervention.

METHODS

Participants included 57 children, 6-12 years old with documented FA, and their mothers. Families were assessed using the Food Allergy Management and Adaptation Scale. Families also completed measures of quality of life, anxiety, FA management, and psychosocial impairment.

RESULTS

A hierarchical cluster analysis revealed that 56 of the 57 families of food-allergic children were categorized into four groups that differed on their adequacy of family FA management, levels of anxiety, and balanced psychosocial functioning: balanced responders (n = 23; 41%), high responders (n = 25; 45%), and low responders (n = 3; 5%). The fourth group, anxious high responders (n = 5; 9%), was characterized by extremely high maternal FA anxiety scores and low scores for balanced integration of FA management and psychosocial functioning. Families in clusters differed across illness and psychosocial outcome variables.

CONCLUSION

Families with FA were characterized by patterns of FA management, anxiety, and ability to integrate FA demands into daily life. Identified adaptation patterns correspond with clinical impressions and provide a framework for identifying families in need of intervention.

Allocation of food allergy responsibilities and its correlates for children and adolescents

This study examined the degree to which children and adolescents with food allergy accept responsibility for their own care, and the extent to which greater self-management is associated with past history of a life-threatening allergic reaction or anxiety. For children (n = 190), caregiver and patient report of self-management was consistent, but agreement was poor for adolescent dyads (n = 59). History of a life-threatening allergic reaction was associated with greater self-management for children only, while among adolescents, it was associated with greater anxiety. Given that shifting to self-management may be challenging, discussion and preparation about this process is warranted.

Mental Health Screening Outcomes in a Pediatric Specialty Care Setting

OBJECTIVE

To evaluate whether a psychosocial screening program that included free and flexible access to mental health (MH) consultation resulted in increased rate of consultations.

STUDY DESIGN

This is a post hoc review of a clinical screening program in a pediatric food allergy clinic in New York City. Screening was limited to 2 days per week, providing an opportunity to compare screened and nonscreened cohorts. Previous results from more than 1000 other families were analyzed to create the 1-page screening questionnaire. Participants were children with allergies and their parents who sought care at the clinic between March and September 2013. Parents were screened for distress and quality of life burden related to their child's allergy, and children were screened for anxiety, bullying, and quality of life. The predefined primary outcome was the percentage of families who received the free MH consultation after screening vs no-screening days in the allergy clinic.

RESULTS

The 3143 encounters during the study period included 1171 on screening days and 1972 on no-screening days. Most (86%) eligible families completed the screen. Almost one-half (44%) met the initial screening thresholds. A total of 71 families (6.1% of screening days encounters) were referred to a MH consultation after a secondary review, but only 11 (1% of screening days encounters) scheduled a MH appointment. Eighteen families from the no-screening days came to a MH evaluation (1% of no-screening days encounters).

CONCLUSION

Screening did not lead to enhanced MH follow-up. Resources may be better used on ensuring the availability of MH care rather than on screening in pediatric specialty clinics.

Quality of Life in Food Allergy Patients and Their Families

Pediatric food allergy is a growing health problem in the United States that has been found to adversely impact the quality of life of both affected children and their caregivers. This article provides a review of how food allergy affects the quality of life of patients and their families within the domains of school, social activities, relationships, and daily life. Efforts to improve food allergy-related quality of life among caregivers are also discussed.

Topical Review: Pediatric Food Allergies Among Diverse Children

OBJECTIVE

To present a brief review of the literature regarding potential racial/ethnic disparities in pediatric food allergy (FA).

METHODS

Topical review considering data regarding FA prevalence, asthma comorbidity, epinephrine access/use, and psychosocial impact (e.g., burden, quality of life).

RESULTS

Methodological variation precludes firm conclusions regarding disparities in prevalence; however, some data suggest Black children may be at particular risk. The comorbidity of FA and asthma among urban populations may increase risk of negative outcomes. There are clear racial/ethnic and socioeconomic disparities in epinephrine access and use. Psychosocial measures are frequently validated on samples that are not racially or ethnically diverse. Studies investigating FA's psychosocial impact are often composed of mostly White, non-Hispanic participants (>85% of study sample).

CONCLUSIONS

Further research is needed to clarify prevalence patterns by race/ethnicity, to investigate the sources of disparity in epinephrine use, and to evaluate the differential impact of FA on diverse children.
