Children's Food Allergies: Development of the Food Allergy Management and Adaptation Scale

Managing food allergies at school: A qualitative study

INTRODUCTION

The prevalence of childhood allergic diseases, including food allergies, has increased globally. Parents and children have experienced psychosocial and financial difficulties, decreased quality of life, anxiety, and depression in the management of food allergies in schools.

PURPOSE

The aim of the study was to determine the challenges experienced by mothers of children with food allergies during their children's school life.

DESIGN

A qualitative phenomenological study design was used.

METHODS

Online interviews were conducted with 9 mothers who have children with food allergies between June-August 2022. The data were analyzed using the content analysis method. The COREQ checklist was used in the study.

RESULTS

The ages of the mothers participating in the study ranged from 28 to 40. Four themes were generated from 75 codes: 1) Problems experienced in the process of utilizing health services, 2) Burden of care, 3) Coming out of the shell: The school process, and 4) Environmental and social perspective.

CONCLUSIONS

Mothers carried the burden of food allergy management during the school process, and the increased burden of care negatively impacted mothers emotionally, physically, and socially. Also, mothers were anxious about the safety of their school-age children with food allergies and their experiences with school administration, teachers, and other parents made it difficult for food allergy management in the school environment.

CLINICAL RELEVANCE

Children with chronic health problems such as food allergies need to be closely monitored by a health professional in school to ensure their safety. Nurses have a pivotal role in supporting families to address their child's food allergies competently, hence fostering positive health outcomes. This study showed that there was a need for the development of school health policies to ensure the safety of children with food allergies and to reduce anxiety and care burden among mothers.

Knowledge and Awareness About Food Allergy Among Mothers With Allergic Children in the Aseer Region, Saudi Arabia

Introduction Food allergies have become a significant health concern worldwide, affecting individuals of all age groups. It is particularly challenging for parents who have children diagnosed with food allergies, as they bear the responsibility of managing their child's condition and ensuring their safety. This study aimed to assess the knowledge and awareness about food allergies among mothers with allergic children in the Aseer region, Saudi Arabia. Methodology A cross-sectional study design was employed, and data were collected through a structured questionnaire administered to 400 mothers. The participants were selected through convenience sampling. Descriptive statistics, including frequencies and percentages, were used to summarize the demographic characteristics, knowledge and awareness levels, prevalence of allergenic foods, manifestations of food allergies, and factors influencing food allergies. Chi-squared tests were conducted to assess associations between variables. Results The study revealed a balanced representation across different age groups among the surveyed mothers, with the highest proportion falling in the 31-40 years range. A significant proportion of mothers had a university education, indicating a relatively higher level of education among the participants. The majority of mothers were employed in governmental positions, followed by housewives and those working in the private sector. Regarding knowledge and awareness, a substantial percentage of mothers correctly identified key aspects of food allergies. However, knowledge gaps were observed, particularly in understanding the hereditary nature. The prevalence of allergenic foods varied, with seafood (fish, shrimp, and tuna) emerging as the most commonly reported allergenic foods, followed by eggs, milk, wheat, chocolate, fruits, nuts, and other food types. Manifestations associated with food allergies were reported, including skin, respiratory, eye, nasal, gastrointestinal, and other symptoms. The associations between different feeding methods and the occurrence of medically diagnosed food allergies were found to be non-significant. However, having other children with food allergies showed a highly significant association with the occurrence of food allergies in the current child. The age of introducing solid food did not demonstrate a significant association with the occurrence of food allergies. Conclusion This study provides insights into the knowledge and awareness about food allergies among mothers with allergic children in the Aseer region, Saudi Arabia. While mothers demonstrated a reasonable understanding of food allergies, knowledge gaps were identified, particularly regarding the hereditary nature. The prevalence of allergenic foods aligns with previous studies, although variations across populations should be considered. The manifestations reported by the participants corroborate known allergic reactions, necessitating further analysis.

Systematic Review of the Incidence and/or Prevalence of Eating Disorders in Individuals With Food Allergies

BACKGROUND

Chronic diseases involving strict dietary adherence have been associated with an increased risk of eating disorders (EDs). This is the first systematic review investigating the rate of EDs among individuals with food allergies (FAs).

OBJECTIVE

To report the incidence, prevalence, and types of EDs in individuals with FAs.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched 4 databases for studies published to January 2022 that reported the prevalence or incidence of EDs in samples with immunoglobulin E (IgE) or non-IgE-mediated allergy. Risk of bias was assessed and evidence qualitatively synthesized.

RESULTS

From 1,180 papers identified, 9 met inclusion criteria. There were 4,161 adult and pediatric participants with IgE-mediated FAs or eosinophilic esophagitis. Avoidant/Restrictive Food Intake Disorder (ARFID) or anorexia nervosa/bulimia nervosa were the main EDs identified. The prevalence of EDs in samples with FA ranged from 0.8% to 62.9%. Among studies investigating IgE-mediated FA (n = 6), the prevalence of anorexia nervosa and/or bulimia nervosa ranged from 17.6 to 61%, ARFID was 62.9%, and unspecified EDs was 0.8% to 6%. Among samples with eosinophilic esophagitis (n = 3), ARFID prevalence ranged from 4.5% to 51%. Most studies were limited by small sample size, possible selection bias, and lack of diagnostic EDs tools validated for food allergic populations.

CONCLUSIONS

Eating disorders appear prevalent in individuals with FA; however, prevalence estimates varied widely. Large studies with healthy control groups and validated measures to identify EDs in individuals with FA are needed to accurately determine the prevalence of EDs.

Children at risk of anaphylaxis: A mixed-studies systematic review of parents' experiences and information needs

Objective

To explore parents' self-reported experiences and information needs regarding recognition and management of pediatric anaphylaxis.

Methods

We searched Ovid Medline, Ovid PsychInfo, CINAHL Plus, the Cochrane Library, and grey literature to identify primary studies in English or French published since 2000. We used a mixed-method appraisal tool and convergent integrated approach to assess quality and synthesize data, respectively.

Results

43 studies were included (22 quantitative, 19 qualitative, and 2 mixed-method); 77% of studies had high methodological quality. Parents' experiences were categorized as: recognizing an anaphylactic reaction; managing and responding to a reaction; emotional impact of caring for a child at risk of anaphylaxis; and interaction with the health system and healthcare providers. Parents' information needs were categorized into themes relating to: gaps in knowledge and information; type of information desired; information sources; and information delivery format.

Conclusion

Negative emotional experiences and a general lack of information were commonly reported by parents of included studies. Provision of relevant and comprehensible information may help parents to make informed decisions and manage reactions promptly.

Innovation

The findings of this review are guiding the development of an innovative knowledge translation tool (KT) as part of a larger initiative of developing a suite of parent-focused KT tools for acute childhood conditions.

Development and Evaluation of a Mobile Web-based Food Allergy and Anaphylaxis Management Educational Program for Parents of School-aged Children with Food Allergy: A Randomized Controlled Trial

PURPOSE

This study aimed to develop a mobile web-based food allergy (FA) and anaphylaxis management educational program for parents of school-aged children with food allergies and evaluate its effectiveness.

METHODS

A mobile program was developed based on a web-based teaching-learning system model. Its effectiveness was subsequently evaluated using a parallel, randomized controlled pre- and post-test design. This study included 73 parents of school-aged children with food allergies. These parents were randomly assigned to either the experimental (n = 37) or control (n = 36) groups. The experimental group participated in a 2-week mobile web-based educational program that covered major topics in FA and anaphylaxis management. These topics included an understanding of food allergies and anaphylaxis, learning techniques for using an epinephrine auto-injector, and developing an emergency action plan. An educational booklet was provided to the control group. Participants completed a pre-test and two post-test questionnaires to evaluate the impact of the program. The assessment tools were the Food Allergy Knowledge Test, Food Allergy Self-Efficacy for Parents, and Food Management and Adaptation Scale. The data were analyzed using descriptive statistics, a test of homogeneity for the pre-test, an independent t-test, and repeated measures ANOVA.

RESULTS

The experimental group experienced greater improvement in the knowledge of FA (post-intervention t = 14.51, p < .001; 2 weeks post-intervention, t = 16.15, p < .001), FA self-efficacy (post-intervention t = 77.99, p < .001; 2 weeks post-intervention, t = 76.09, p < .001), and practice behavior in FA management (post-intervention t = 28.10, p < .001; 2 weeks post-intervention, t = 27.98, p < .001) after web-based FA education.

CONCLUSION

This study revealed improvements in the knowledge, self-efficacy, and practice behaviors of parents regarding FA and anaphylaxis management. Therefore, the mobile web-based educational program can contribute to the effective management of food allergies and anaphylaxis for parents of school-aged children. CRIS registration: KCT0007491.

A systematic review of parent report measures assessing the psychosocial impact of food allergy on patients and families

BACKGROUND

Reducing the psychosocial impact of food allergy (FA) represents a top patient-centered research priority. This priority recognizes that psychosocial impact is an important outcome of current FA therapies (eg, oral immunotherapy), as well as interventions aimed at improving overall quality of life and illness adaptation. Reliable and valid measurement is a necessary prerequisite to developing and evaluating current and emerging FA therapies and potential changes in psychosocial impact.

METHODS

In this systematic review, we applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to evaluate available parent report measures assessing the psychosocial impact of pediatric IgE-mediated FA.

RESULTS

The systematic search yielded 64 articles involving 13 unique measures. Measures were evaluated through the lens of the Patient Reported Outcomes Measurement Information System (PROMIS) guidelines. Findings indicated that available measures show some evidence of reliability and validity; however, none completely adhere to PROMIS guidelines for measure development.

CONCLUSION

Results highlight a continued need to dedicate research to develop a measurement approach that assesses the full range of psychosocial impact that parents and families may experience as a result of FA, as well as serve as a research outcome as the field continues to develop effective treatments, including immunotherapy.

Psychometric Properties of a Measure Assessing Anxiogenic Parenting Practices in Food Allergy

Aim

Pediatric food allergy represents a significant public health burden. In order to avoid allergen consumption, adequate management requires daily vigilance and involvement from parents, frequently leading to increased parental anxiety. While specific anxiogenic parenting practices (i.e., parenting behaviors which may aid in the development and/or exacerbation of childhood anxiety) have been documented within this population, to this point, these behaviors have not been systematically measured.

Objectives

The current study aimed to develop and examine a parent-report scale designed to measure anxiogenic parenting behaviors related to food allergy.

Methods

Participants included 177 parents of children with food allergy recruited online using Amazon Mechanical Turk (mTurk). An exploratory factor analysis was conducted to determine the factor structure of the newly developed scale. Subsequently, psychometric properties (e.g., construct validity) were examined via correlational analyses.

Results

Results indicated a 24-item, 3 factor (Factor 1: Involvement in Food Allergy; Factor 2: Worry about Food Allergy; Factor 3: Autonomy Promotion) scale, which accounted for 53.11% of the total variance. The Kaiser–Meyer–Olkin measure was acceptable, KMO = 0.872 and Bartlett’s test of sphericity indicated sufficient correlations between items (χ2 (378) = 2568.95). All subscales demonstrated strong internal consistency (Involvement in Food Allergy: α = .880; Worry about Food Allergy: α = .892; Autonomy Promotion α = .796) as well as convergent and discriminant validity.

Conclusions

Results support the overall psychometric properties of the scale. Interpretations, limitations, and future directions are discussed.

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.

Development of the Child- and Parent-Rated Scales of Food Allergy Anxiety (SOFAA)

BACKGROUND

Anxiety can be excessive and impairing in children with food allergy (FA). There is no accepted condition-specific measure of anxiety for this population.

OBJECTIVE

To evaluate the validity and reliability of new child- and parent-rated measures of FA-related anxiety in youth.

METHODS

Items for the Scale of Food Allergy Anxiety (SOFAA) were developed by a cognitive-behavioral therapist specializing in pediatric anxiety, in consultation with FA medical professionals and parents of children with FA. Dyads (n = 77) of children with FA (aged 8-18 years; 42.9% females) and their parents (95.5% females) completed full versions of the SOFAA (21 items; scored 0-4) via online survey.

RESULTS

The child-rated SOFFA-C mean score was 29.1 ± 18.3; the parent-rated SOFAA-P mean score was 33.9 ± 16.1. Higher scores indicate higher reported anxiety. Coefficient alphas were 0.94 and 0.92. Factor analyses and item-response theory analyses supported the creation of the 14-item SOFAA-C-brief and the 7-item SOFAA-P-brief, accounting for 93% and 79% of total variance, respectively. Correlations revealed strong convergence between child- and parent-report for both the full (r = 0.85) and brief (r = 0.79) versions. Correlations with a generic measure of child anxiety (Screen for Child Anxiety Related Disorders) and the Food Allergy Quality of Life Questionnaire ranged from moderate to strong, whereas those with a generic measure of child eating problems (About Your Child's Eating) were weak to moderate, supporting convergent and divergent validity. Scores of 48 dyads who completed SOFAAs at time 2 (mean, 16.0 days) appeared stable over time, supporting test-retest reliability.

CONCLUSIONS

The 21-item SOFAA-C and SOFAA-P are reliable and valid scales for measuring condition-specific anxiety in youth with FA. As shorter screening measures, the SOFAA-C-brief and the SOFAA-P-brief are also reliable and valid.

Selected Instrumental Techniques Applied in Food and Feed: Quality, Safety and Adulteration Analysis

This review presents an overall glance at selected instrumental analytical techniques and methods used in food analysis, focusing on their primary food science research applications. The methods described represent approaches that have already been developed or are currently being implemented in our laboratories. Some techniques are widespread and well known and hence we will focus only in very specific examples, whilst the relatively less common techniques applied in food science are covered in a wider fashion. We made a particular emphasis on the works published on this topic in the last five years. When appropriate, we referred the reader to specialized reports highlighting each technique's principle and focused on said technologies' applications in the food analysis field. Each example forwarded will consider the advantages and limitations of the application. Certain study cases will typify that several of the techniques mentioned are used simultaneously to resolve an issue, support novel data, or gather further information from the food sample.

Patients' Perspectives and Needs on Novel Food Allergy Treatments in the United States

PURPOSE

Food allergy management places a daily psychosocial burden on patients and their caregivers. New food allergy treatments may positively impact their lives, but also introduce new stressors. The purpose of this paper is to provide an overview of the current state of the literature regarding patients' and caregivers' food allergy experiences and needs within the United States as well as a set of recommendations regarding how best to proceed with patient-centered development and evaluation of new food allergy treatments.

RECENT FINDINGS

The first pharmaceutical-grade product for peanut oral immunotherapy was approved in the United States for children aged 4-17 years following a successful international Phase 3 trial. This new treatment is only the first of several food allergy treatments currently under development. Patients will soon be presented with multiple options for food allergy treatment and will need to make decisions about what treatment is best for them.

SUMMARY

Allergy researchers and providers are encouraged to consider patients' perspectives and needs when developing and evaluating new food allergy treatments. Recommendations regarding next steps include the development of new patient-reported outcome tools, focus on psychosocial support, health disparities, and financial implications, and research harmonization and interdisciplinary collaboration.

Assessing Parental Anxiety in Pediatric Food Allergy: Development of the Worry About Food Allergy Questionnaire

Food allergies (FAs) in children are increasingly common, and strict allergen avoidance and safety concerns place parents at risk for anxiety (Lau et al. in Pediatr Allergy Immunol 25:236-242, 2014). Assessing parental anxiety with generic instruments may not capture the unique experience of parents managing children's FAs. This study developed and preliminarily validated the 13-item Worry About Food Allergy (WAFA) questionnaire, a measure of FA-specific parental anxiety, in an online sample of 265 parents aged 22-66 (M = 40.25) of children with FAs. The WAFA showed good internal reliability (Cronbach's α = .89) and moderate convergent validity with other anxiety measures, indicating support for a reliable measure of a discrete, specific construct. Exploratory factor analysis indicated a single factor structure. Criterion validity was established through significant, small, positive correlations with relevant allergy variables. A coherent single factor measure, the WAFA, shows promise as a screening tool for parental anxiety in pediatric practice and FA management.

Food insecurity and caregiver perceptions of food allergen risk by food purchase location in children with food allergies

Meeting nutritional needs of children with food allergy (FA) may be challenging without affordable, quality foods. Food purchase location may impact availability of FA-safe foods; however, no research examining food purchase location in families of children with FA exists. This study compared caregiver report of food insecurity (FIS; food insecure vs. food secure), FA risk, and history of food-induced anaphylaxis (FIA) in families of children with FA, who primarily purchase food items at grocery/supermarkets (n = 140) or convenience marts/bodegas (CB; n = 32). Caregivers (N = 172; 49% mothers, 49% fathers, 2% grandparent/other relative) of children with FA (57% male; Mage = 7.5 years; 66% White [22% Latinx and 44% non-Latinx] and 23% Black) completed an online survey. Variables included demographics, history of FIA, and caregiver perceptions of FIS and FA risk. Caregivers who purchased food items from CB versus supermarkets reported higher perceived risk of accidental ingestion (χ2 = 20.49, p < .001, 94% vs. 50%), severe reaction (χ2 = 15.05, p < .001, 97% vs. 61%), death (χ2 = 27.48, p < .001, 91% vs. 49%), FIS (χ2 = 21.69, p < .001, 94% vs. 49%), and FIA (χ2 = 11.96, p = .001, 94% vs. 32%). Effect sizes were small-moderate (Cramer's V = .26-.40). Families who purchased food at CB reported greater food allergen concerns and FIS than families who purchased food at supermarkets. Differences in FA-related perceived risks may reflect the health disparity and adversity these families face to meet basic nutritional needs, such as FA-related constraints. Point-of-care efforts are needed to provide early screening for families who may be at risk for experiencing FIS.

Harmonization of Terminology for Tolerated and Reactive Dose in Food Allergy Immunotherapy

Currently, there is no Food and Drug Administration-approved therapy for food allergy. Several new potential treatments are under investigation, including food allergen immunotherapy via various routes of administration, such as oral immunotherapy, epicutaneous immunotherapy, subcutaneous immunotherapy, and sublingual immunotherapy. The double-blind, placebo-controlled food challenge (DBPCFC) has traditionally been used for diagnostic purposes, but extrapolation of the specific terminology used in food allergy diagnosis to interpretation of efficacy in clinical trials is incongruent and difficult to apply. There is a need for standardization of the terminology used in food allergy clinical trials, because inconsistencies can lead to potential misinterpretation of end points. The reactive dose, previously referred to as the eliciting dose, is defined as the dose given that induces the onset of unequivocal allergic symptoms, or the dose that stops the challenge based on physician discretion. Conversely, the single highest tolerated dose is defined as the highest dose given during a food challenge that elicits either no symptoms or symptoms that do not meet stopping criteria per the study protocol. The evolving field of food allergy provides a novel opportunity to define those end points that are most meaningful for patients, which is fundamental for successful implementation, education, and safety.

Stressors of School-age Children With Allergic Diseases: A Qualitative Study

PURPOSE

Most studies of stress in children with chronic diseases have been geared toward parents and caregivers have not considered allergic diseases together. This study aimed to identify the stressors associated with allergic diseases in Japanese school-age children.

DESIGN AND METHODS

Stressors associated with allergic diseases of 11 school-age children (seven boys and four girls; age range: 9-12 years) were investigated using semi-structured interviews.

RESULTS

In the qualitative thematic analysis of stressors about allergic diseases, two themes: allergic disease-specific stressors and common stressors in chronic diseases, and 12 categories were identified. A thematic map was applied to four domains of stressor: physiological factors, psychological factors, social factors, and environmental factors.

CONCLUSIONS

The results showed that school-age children with allergic diseases have a variety of stressors. Future studies should aim to develop an allergic disease-specific stress management program with school-age children.

PRACTICE IMPLICATIONS

In children with allergic diseases, not only is stress management in daily life important, but also stress management for disease-specific matters to control the symptoms and maintain mental health. Stress management should be supported for school-age children with allergic diseases.

Food Allergy and Anxiety and Depression among Ethnic Minority Children and Their Caregivers

OBJECTIVE

To investigate the relationship between food allergy and symptoms of anxiety and depression among ethnic minority, low socioeconomic status (SES) children and their caregivers.

STUDY DESIGN

Pediatric patients ages 4-12 years with and without food allergy and their caregivers were recruited from urban pediatric outpatient clinics. Statistical analyses were used to examine the prevalence of symptoms of anxiety and depression among patients and their caregivers with and without food allergy, adjusting for asthma.

RESULTS

Eighty patients ranging from ages 4 to 12 years, with a mean age of 8.1 years, and their caregivers participated in the study. Food allergy was associated with significantly higher t scores on the Multidimensional Anxiety Scale for Children (MASC) Total (P = .007), MASC Humiliation Rejection, (P = .02) and MASC Social Anxiety (P = .02) among pediatric patients, adjusting for asthma. Food allergy was not associated with child depression symptoms, nor was there a significant difference in anxiety or depression symptoms among caregivers of patients with and without food allergy.

CONCLUSIONS

Food allergy appears to be associated with increased symptoms of social anxiety and higher levels of anxiety overall, but not depression, in ethnic minority children of lower socioeconomic status. This finding was not due to confounding by asthma. Food allergy was not associated with higher levels of depression or anxiety symptoms among caregivers of pediatric patients with food allergy. Future studies should investigate potential pathways between food allergy and anxiety that may be unique to children in underserved populations, and develop interventions to reduce anxiety in children with food allergy.

Clinical Management of Psychosocial Concerns Related to Food Allergy

Current estimates indicate that 4% to 8% of children in the United States are diagnosed with food allergy, and more than 40% of US children with food allergy experience severe allergic reactions. Families trying to avoid foods that may trigger an allergic reaction and ensure adequate treatment of allergic reactions that do occur face numerous challenges. The rise in the number of children diagnosed with food allergies underscores the importance of food allergy-related interventions to address elevated psychosocial concerns, such as parenting stress, anxiety, and worries about bullying. This review provides an overview of common psychosocial concerns among children with food allergy and their families across the developmental spectrum, and offers guidance to medical providers regarding the identification and treatment of food allergy-related psychosocial challenges.

Can we identify patients at risk of life-threatening allergic reactions to food?

Anaphylaxis has been defined as a 'severe, life-threatening generalized or systemic hypersensitivity reaction'. However, data indicate that the vast majority of food-triggered anaphylactic reactions are not life-threatening. Nonetheless, severe life-threatening reactions do occur and are unpredictable. We discuss the concepts surrounding perceptions of severe, life-threatening allergic reactions to food by different stakeholders, with particular reference to the inclusion of clinical severity as a factor in allergy and allergen risk management. We review the evidence regarding factors that might be used to identify those at most risk of severe allergic reactions to food, and the consequences of misinformation in this regard. For example, a significant proportion of food-allergic children also have asthma, yet almost none will experience a fatal food-allergic reaction; asthma is not, in itself, a strong predictor for fatal anaphylaxis. The relationship between dose of allergen exposure and symptom severity is unclear. While dose appears to be a risk factor in at least a subgroup of patients, studies report that individuals with prior anaphylaxis do not have a lower eliciting dose than those reporting previous mild reactions. It is therefore important to consider severity and sensitivity as separate factors, as a highly sensitive individual will not necessarily experience severe symptoms during an allergic reaction. We identify the knowledge gaps that need to be addressed to improve our ability to better identify those most at risk of severe food-induced allergic reactions.

The Emperor Has No Symptoms: The Risks of a Blanket Approach to Using Epinephrine Autoinjectors for All Allergic Reactions

Fatal anaphylaxis in humans is rare and unpredictable. We note a trend to provide allergic individuals with care plans that recommend immediate use of epinephrine autoinjectors if allergen ingestion is suspected, even in the absence of any allergic symptoms, without any supporting evidence base. Instructions to use an autoinjector device, irrespective of reaction severity and especially when symptoms are actually absent, are likely to add to parental and patient anxiety. Of greater concern is the possibility of epinephrine being administered “too early” to treat initial, mild symptoms that then progress to severe anaphylaxis. It is not hard to visualize a scenario where one or both epinephrine autoinjectors have been deployed for mild symptoms, yet the reaction progresses to a severe reaction and no further epinephrine is available for administration. Epinephrine needs to be available as a rescue treatment for anaphylaxis, potentially buying valuable minutes while emergency medical services are activated to attend. Food-allergic individuals and their carers need to be provided with more constructive strategies and support than merely being told to “use your pen.”

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.

Evaluating a handbook for parents of children with food allergy: a randomized clinical trial

BACKGROUND

Educational materials are needed to support parent management of and coping with childhood food allergy.

OBJECTIVES

To evaluate whether a food allergy handbook can improve parental knowledge, confidence, and quality of life associated with the management of food allergy.

METHODS

Participants included 153 parents of children diagnosed as having food allergy within the past 12 months who were recruited from hospital-based allergy clinics and food allergy organizations. Parents were randomly assigned to receive the food allergy handbook either after a baseline survey (handbook group) or at the conclusion of study participation (control group). Outcomes were assessed using online surveys at baseline, 2-week follow-up, and 2-month follow-up.

RESULTS

Compared with parents in the control group, parents in the handbook group had significantly greater improvement in knowledge at the 2-week (mean difference, 2.92; 95% confidence interval [CI], 2.20-3.64; P < .001) and 2-month (mean difference, 2.46; 95% CI, 1.68-3.25; P < .001) follow-ups, significantly greater improvement in confidence at the 2-week (mean difference, 0.24; 95% CI, 0.09-0.39; P = .002) and 2-month (mean difference, 0.47; 95% CI, 0.30-0.63; P < .001) follow-ups, and significantly greater improvement in quality of life at the 2-month follow-up (mean difference, -0.48; 95% CI, -0.79 to -0.16; P = .004). Parents reported satisfaction with the content the handbook, with mean ratings of individual sections ranging from 2.7 to 3.2 on a 0- to 4-point scale and modal ratings of 3 (very useful).

CONCLUSIONS

The food allergy handbook evaluated in this study is an effective parent resource to supplement physician management of food allergy.

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.
