Quality of Life, Stress, and Mental Health in Parents of Children with Parentally Diagnosed Food Allergy Compared to Medically Diagnosed and Healthy Controls

Systematic review and meta-analyses on the accuracy of diagnostic tests for IgE-mediated food allergy

The European Academy of Allergy and Clinical Immunology (EAACI) is updating the Guidelines on Food Allergy Diagnosis. We aimed to undertake a systematic review of the literature with meta-analyses to assess the accuracy of diagnostic tests for IgE-mediated food allergy. We searched three databases (Cochrane CENTRAL (Trials), MEDLINE (OVID) and Embase (OVID)) for diagnostic test accuracy studies published between 1 October 2012 and 30 June 2021 according to a previously published protocol (CRD42021259186). We independently screened abstracts, extracted data from full texts and assessed risk of bias with QUADRAS 2 tool in duplicate. Meta-analyses were undertaken for food-test combinations for which three or more studies were available. A total of 149 studies comprising 24,489 patients met the inclusion criteria and they were generally heterogeneous. 60.4% of studies were in children ≤12 years of age, 54.3% were undertaken in Europe, ≥95% were conducted in a specialized paediatric or allergy clinical setting and all included oral food challenge in at least a percentage of enrolled patients, in 21.5% double-blind placebo-controlled food challenges. Skin prick test (SPT) with fresh cow's milk and raw egg had high sensitivity (90% and 94%) for milk and cooked egg allergies. Specific IgE (sIgE) to individual components had high specificity: Ara h 2-sIgE had 92%, Cor a 14-sIgE 95%, Ana o 3-sIgE 94%, casein-sIgE 93%, ovomucoid-sIgE 92/91% for the diagnosis of peanut, hazelnut, cashew, cow's milk and raw/cooked egg allergies, respectively. The basophil activation test (BAT) was highly specific for the diagnosis of peanut (90%) and sesame (93%) allergies. In conclusion, SPT and specific IgE to extracts had high sensitivity whereas specific IgE to components and BAT had high specificity to support the diagnosis of individual food allergies.

Living with food allergies: the experiences of adult patients and caregivers

Background

Few studies have addressed how food allergy may impact differently on the daily lives of adults with food allergies and caregivers for food-allergic dependents.

Objective

To explore similarities and differences in life experiences and unmet needs between individuals caring for a child with food allergy and adults with food allergy world-wide.

Methods

Two multinational, virtual, interactive, moderated discussions of specific questions between respectively people with food allergies and caregivers for people with food allergies, with experienced clinicians participating.

Results

Sixteen individuals living with food allergies and nine caregivers took part in the two roundtables. Food avoidance and antihistamines were the most common treatments for food-allergic reactions in both groups. Caregivers reported greater burden of disease on affected individuals and families than did adult patients. Adult panelists considered autoinjectors easy to use but caregivers reported additional emotional stress thinking about autoinjector use. Caregivers described an ever-present fear of inattention and of overlooking a risk factor for a severe reaction, whereas adult panelists showed a determination not to let their food allergies interfere with living their lives. Both groups had safety-conscious attitudes to treatments, but adult patients emphasized convenience while caregivers prioritized reduced severity of reactions and eliminated fear. Both groups confirmed the need for improved, trusted sources of information, and for resources and training programs for any new therapies.

Conclusion

The interactive exchange provided insights into differences between adult patients and caregivers, notably in fear and confidence in daily life, severity of disease impact, and unmet needs for treatments.

Quality of life in children with food allergies, psychiatric symptoms, and caregiving burden of their mothers

OBJECTIVE

The present study aimed to evaluate the quality of life in children with food allergies, the accompanying depression and anxiety disorders, and caregiving burden of their mothers.

MATERIAL AND METHODS

A total of 168 children with food allergy visiting our clinic and their mothers were included in the study group. The control group included 152 children who visited the healthy child follow-up clinic of our hospital and their mothers. Studying mothers' opinions, the Food Allergy Quality of Life Questionnaire Parent Form (FAQLQ-PF) was used for evaluating children, and the Beck's Depression Inventory, Beck's Anxiety Inventory, Temperament Evaluation of Memphis, Pisa, Paris, San Diego Auto-questionnaire, and Zarit Caregiver Burden Scales were used for evaluating mothers.

RESULTS

No differences were noticed between the study and control group regarding mean age and gender distribution (P > 0.05). In the study, the FAQLQ-PF total and subscale scores of children with food allergies were determined according to the opinions of their mothers, and scores tended to increase with age (P < 0.0001). In addition, it was determined that mothers of children with food allergies had higher levels of anxiety, depression, and caregiving burden than mothers of the control group (P < 0.0001).

CONCLUSION

In order to develop a multidisciplinary approach for children with food allergies, we conceived as appropriate to inform their families about the difficulties of caregiving and psychosocial disorders that could develop over time. They also must be informed to take preventive measures as well as the medical aspects of their children's disease.

Parental Knowledge about Allergies and Problems with an Elimination Diet in Children Aged 3 to 6 Years

Allergic diseases are highly prevalent, and they can exert a significant influence on the patients’ physical and mental well-being, thus affecting the quality of their lives and society as a whole. The aim of this study was to evaluate parental knowledge about allergens, allergy symptoms, and treatment of allergies, and to identify problems with adherence to an elimination diet and the underlying difficulties. Twelve kindergartens and the parents of 1350 preschoolers took part in the first stage of the study. In a screening trial, allergies were diagnosed in 197 children, and their parents participated in the second stage of the study. The child’s age at the onset of the first symptoms was significantly correlated with allergy type. Age was significantly correlated with selected symptoms of an allergic reaction, and skin allergies were more prevalent in younger children. Erythema, skin reddening, and urticaria occurred more frequently in children aged 3−4 years (OR 1.45; 95%CI 1.24−1.77, p < 0.05) and were diagnosed in skin tests (OR 1.36; 95%CI 1.22−1.59, p < 0.05). Allergies to numerous food items were associated with a long-term elimination diet (OR 1.89; 95%CI 1.33−2.19, p < 0.01), as well as problems with preparing safe meals, shopping for food, or dietary adherence when eating out. According to the respondents, lack of support from other family members and compliance with dietary restrictions in kindergartens and when eating out posed the greatest barriers to dietary adherence. Parents do not have sufficient knowledge about environmental allergens and effective strategies for coping with acute allergic reactions, including anaphylactic shock. Children with diagnosed food allergies should enjoy a similar quality of life to their healthy peers, which is why the parents should be educated about diet therapy, duration of treatment, and safe food substitutes.

Attitudes Towards Food Allergy Scale: Psychometric properties and associations with food allergy quality of life and anxiety

Background

Daily, we tend to evaluate things positively or negatively, according to whether they follow the general information available about them. This attitudinal assessment is represented through evaluative dimensions (e.g., good‐bad) that vary in terms of valence (positive or negative) and strength (less or more). Despite its importance, there is an urge in food allergy (FA) research to properly assess attitudes based on the underlying mechanisms that define attitudes.

Objective

The present research aimed to develop the Attitudes Towards Food Allergy scale (ATFAS), the first attitudinal measure of FA. Method: Two studies were performed (n = 1049), using a range of robust statistical analyses (e.g., Item Response Theory, Exploratory Factor Analysis, Confirmatory Factor Analysis).

Results

Our results provided strong evidence for a unidimensional attitudinal structure, across groups of non‐allergic individuals and food‐allergic, besides recommended reliability levels. All items presented suitable parameters (i.e., discrimination, difficulty, information). Finally, the ATFAS significantly predicted FA quality of life, mediated by FA anxiety.

Conclusion

We are confident that the ATFAS is a novel and necessary measure, that can help to widen how we view and assess FA. The development of studies that assess attitudes towards FA based on our general information about the disorder would help to deepen our understanding of their links to other health‐related variables and their potential impact on quality of life, reduce FA's stigma, and develop more positive attitudes.

Development of IMPAACT (Impairment Measure for Parental Food Allergy-Associated Anxiety and Coping Tool), a validated tool to screen for food allergy-associated parental anxiety

BACKGROUND

Parents commonly experience anxiety owing to their children's food allergies (FAs). Although FA-specific anxiety screening tools for adult and pediatric patients exist, a tool for parents with children with food allergy is lacking.

OBJECTIVE

To develop and validate a tool that measures parental anxiety related to their child's FA.

METHODS

To construct the instrument, items were developed based on consultations with stakeholders and review of existing literature. The instrument was then pilot tested, and items were modified based on relevance, importance, item-total correlations, and fit with the instrument's overall factor structure. The modified instrument was validated through assessing internal validity (reliability), convergent and discriminant validity, concurrent validity, and practical usefulness at 2 time points (precoronavirus disease 2019 and current).

RESULTS

The scale showed excellent reliability (Cronbach's α = 0.95). It had a 4-factor structure that was replicated at the 2 time points. The 4 subscales were moderately correlated (between r = 0.438 and 0.744). The scale showed excellent convergent and discriminatory validity, correlating moderately with State Trait Anxiety Inventory and Generalized Anxiety Disorder, and highly with Food Allergy Quality of Life-Parental Burden. It also showed excellent concurrent validity, differentiating among many external variables. Most importantly, it successfully differentiated parents in need of psychological support for problems related to their child's FA.

CONCLUSION

The Impairment Measure for Parental Food Allergy-associated Anxiety and Coping Tool fills a gap in the existing literature as a validated screening tool for parental anxiety associated with a child's FA, employing a multi-factor structure addressing multiple dimensions of anxiety and its functional impacts. It has excellent internal and external validity and is well-suited for use in both research and clinical settings to quickly determine which parents of children with FA are in need of further psychological support.

Evaluating an online self-help intervention for parents of children with food allergies

BACKGROUND

Parents of children with food allergies (CwFA) experience reduced quality of life (QoL) and may have reduced access to in-person interventions in the COVID-19 pandemic. This trial developed and evaluated an online, self-help, information provision website, aimed at improving QoL in parents of CwFA.

METHODS

In a single-blinded, randomised controlled trial (RCT), participants were randomised to either receive access to the website or a waiting-list control. At baseline, post-intervention (week 4) and follow-up (week 8), measures of parental food allergy-related QoL, depression, anxiety, stress, intolerance of uncertainty (IU) and self-efficacy were obtained.

RESULTS

A total of 205 participants were randomised; 97% were females, 91% white and 78% educated ≥ degree level, with a mean age of 38.95 years (SD = 6.89). 44.9% (n = 92) were retained at follow-up. The arms did not significantly differ on any outcome at any time point. For a sub-group of participants above the clinical cut-off for depression at baseline, the intervention may have improved QoL. Participants reported the website content as useful and accessible, but accessed it infrequently. In baseline data, IU and self-efficacy were significantly associated with QoL.

CONCLUSION

While the COVID-19 pandemic has encouraged greater provision of online interventions, our RCT suggests this particular website is not suitable for this population in general, although future research could examine its efficacy for depressed parents of CwFA, to increase confidence that the sub-group finding was not a Type 1 error. The baseline data suggest IU and self-efficacy remain potential proximal targets for intervention.

The relationship between dietary elimination and maternal psychopathology in breastfeeding mothers of infants with food allergy

BACKGROUND

There has been no study evaluating the psychopathology in breastfeeding mothers of infants with food allergy (FA).

OBJECTIVE

The aim of the study was to investigate the relationship between dietary elimination and maternal psychopathology, specifically anxiety, depression, and mother-to-infant bonding, in breastfeeding mothers of infants with food allergy.

METHODS

Breastfeeding mothers following an elimination diet due to FA in their children aged 1-to-12 months were compared with the healthy controls. The physician-diagnosed FA group was divided into IgE-, non-IgE-mediated, and infants with some minor symptoms which were not enough to make the diagnosis of FA were classified as Indecisive symptoms for FA group. Mothers completed standardized questionnaires including Symptom Checklist 90R, Beck Depression/Anxiety Inventories (BDI/BAI), Postpartum Bonding Questionnaire (Bonding).

RESULTS

Of 179 mother and infants, 64 were healthy, 89 were FA, 16 were indecisive symptoms for FA. The mean age of the mothers and infants were 31.1 ± 4.7 years and 6.3 ± 3.6 months, respectively. The physician-diagnosed FA groups had higher scores for anxiety (p = .008), anger (p = .042), depression (p < .001), obsession (p = .002), phobia (p = .008), somatization (p = .002), general symptom index (GSI) (p = .001), BDI (p < .001), BAI (p = .008), and Bonding (attachment [p = .001], anger [p = .019], and total [p = .036]) than the healthy ones. The indecisive symptoms for FA group had a similar score pattern to physician-diagnosed FA, except interpersonal sensitivity, BDI, and attachment.

CONCLUSION

Breastfeeding mothers of infants with FA were more anxious, with higher depression scores than controls, and had many psychopathologies which affected bonding. Interventions targeting negativity in caregivers' social relationships are urgently needed.

The self-management work of food hypersensitivity

Background

Food hypersensitivity (FH) has received considerable attention in the scientific community in recent years. However, little attention has been given to the efforts people make to manage their FH. We aimed to explore these efforts by using Normalization Process Theory, which is a conceptual framework formerly used to describe the self-management ‘work’ of long-term conditions.

Methods

We carried out qualitative individual interviews with 16 women with FH. Transcripts from recorded interviews were analyzed using template analysis.

Results

16 women participated; some had diagnoses from conventional medicine (celiac disease, lactose intolerance, food allergies, irritable bowel syndrome) and some did not. Participants described carrying out several tasks, some of which were time-consuming, to manage their FH. Women who had clarified once and for all what food(s) caused symptoms, described that they could concentrate on carrying out a restricted diet, which could become routine. Conversely, participants who had not achieved such clarification described carrying out tasks to identify what food(s) caused symptoms, and to implement and evaluate a tentative diet. Participants’ descriptions also revealed a heightened vigilance when they ate food that others had prepared, and some made efforts to conceal their FH.

Conclusions

Self-management of FH may, like the self-management of other long-term conditions, imply a large workload and burden of treatment. Efforts made to conceal FH may be considered part of this workload, while help in clarifying which food(s) cause symptoms has the potential to reduce the workload.

The Psychosocial Impact of Food Protein-Induced Enterocolitis Syndrome

BACKGROUND

Little is known about the psychosocial impact of food protein-induced enterocolitis syndrome (FPIES).

OBJECTIVE

To characterize quality of life, stress, worry, anxiety, and self-efficacy in caregivers of children with FPIES and affected children, and determine risk factors for increased psychosocial burden.

METHODS

Surveys completed by caregiver-members of the International FPIES Association at a conference (n = 42) and online (n = 368) were analyzed.

RESULTS

There was significant burden, stress, worry, and anxiety among caregivers. There was a positive correlation among Food Allergy Quality of Life-Parental Burden, Perceived Stress Scale-10, Penn State Worry Questionnaire, and Beck Anxiety Inventory scores, and these were negatively associated with Food Allergy Self-Efficacy for Parents (FASE-P) scores. Lower income was associated with poorer caregiver health-related quality of life (HRQoL) (P = .039) and lower FASE-P (P = .028). Greater number of food groups avoided correlated moderately with poorer HRQoL (r = 0.386; P < .001), higher anxiety among preschoolers (r = 0.262; P = .013) and parents (r = 0.594, P = .025). Avoiding cow's milk due to FPIES was associated with poorer caregiver HRQoL (P < .001), higher stress (P = .001), and lower FASE-P (P = .013). Caregivers whose child was not attending daycare/school due to FPIES had poorer HRQoL (P < .001), higher stress (P < .014), and worry (P = .004). Compared with published cohorts of caregivers of children with IgE-mediated food allergy, the burden of FPIES on caregivers was significantly higher (mean = 3.4 vs 3.0; P < .001) and self-efficacy was significantly lower (mean = 63.9 vs 76.1; P < .001).

CONCLUSIONS

There is increased stress, worry, anxiety, and reduced HRQoL and self-efficacy among caregivers of children with FPIES and increased general anxiety among preschoolers. Additional research is needed to inform effective psychosocial interventions.

APPEAL-1: A pan-European survey of patient/caregiver perceptions of peanut allergy management

BACKGROUND

Peanut allergy (PA) is associated with marked quality-of-life (QoL) impairment. However, data are lacking on the experience and impact of living with PA from the perspectives of persons with PA (PwPA) and their caregivers. Allergy to Peanuts imPacting Emotions And Life study 1 (APPEAL-1) was a pan-European survey investigating these perspectives. This first of two articles reports clinical characteristics of PwPA and PA management practices.

METHODS

APPEAL-1 was a quantitative, online survey conducted in eight European countries, developed by eight representatives of patient advocacy groups and five healthcare professionals and researchers. Eligible participants included adults with PA and parents/caregivers of PwPA who responded by self-report and provided proxy-report for the PwPA under their care. Data were summarized using nonweighted descriptive statistics.

RESULTS

Of 1846 completed/analysed questionnaires, 528 were from adults with PA (self-report); 437 by proxy for children with PA (34 aged 0-3 years, 287 aged 4-12 years, 116 aged 13-17 years) and 881 from parents/caregivers (self-report). Of PwPA (N = 965), 95% reported diagnosis by healthcare professionals, mostly by clinical history and peanut-specific allergy testing. Rates of allergic rhinitis, asthma and other food allergies in PwPA were 50%, 42% and 79%, respectively. Only 31% of PwPA received HCP advice/support following their worst allergic reaction, and 28% had not been prescribed an adrenaline auto-injector. Results were similar by country but varied by age group.

CONCLUSIONS

The APPEAL-1 findings contribute to greater understanding of PA impact on PwPA, caregivers and family members and the need for improved PA management across Europe.

Interventions for caregivers of children with food allergy: A systematic review

BACKGROUND

Studies have identified that food allergy (FA) in children is related to poorer caregiver quality of life (QoL). However, it is unclear which interventions are most effective at improving outcomes for caregivers of children with FA. This review aimed to identify and determine the efficacy, acceptability and quality of interventions for caregivers of children with FA.

METHODS

A systematic search of four databases was conducted to identify studies evaluating any intervention that targeted well-being and support of caregivers of children with FA. Studies were not excluded based on design and were rated for quality using the Mixed Methods Appraisal Tool (MMAT) and the Cochrane risk of bias tool for randomized controlled trials (RCTs).

RESULTS

Fifteen studies met the inclusion criteria: eight studies used a pre-test/post-test design, four studies used a post-test design, two studies used an RCT design, and one study used a case-control design. Seven studies were educational interventions, five were psychological interventions, and three involved peer/professional support. All interventions had high participant acceptability; some evidence for cognitive behavioural interventions in supporting mothers was observed. Educational interventions tended to be associated with improvements in FA knowledge. With the exception of three studies, most studies were assessed as poor or moderate in terms of quality.

CONCLUSION

There is a paucity of high-quality research evaluating interventions to improve outcomes in parents of children with FA. Limited evidence suggests that cognitive behavioural interventions could benefit some mothers, but this has not been tested in other populations. Future research should use methodologically sound designs with validated outcome measures.

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.

Psychosocial and productivity impact of caring for a child with peanut allergy

Background

Limited previous research has assessed the psychosocial burden and productivity impact of caring for a child with peanut allergy and factors associated with burden. The objective of this research was to explore caregiver burden in terms of psychosocial and productivity impact of caring for a child with peanut allergy, the influence of caregiver and child gender on caregiver burden, and factors predicting caregiver burden in peanut allergy.

Methods

A cross-sectional survey of caregivers of children with peanut allergy was conducted in the United Kingdom, and included sociodemographic and clinical questions, EQ-5D, Hospital Anxiety and Depression Scale, Food Allergy Quality of Life-Parental Burden, Food Allergy Independent Measure, and productivity questions.

Results

One hundred caregivers (55% female) of children with peanut allergy (aged 4-15 years) completed the survey. Male and female caregivers reported mean levels of anxiety significantly higher than United Kingdom population norms. Caregivers of children with severe peanut allergy reported significant impacts on their careers and health-related quality of life. Neither caregiver nor child gender impacted burden, indicating that male and female caregivers are equally anxious and suffer the same level of negative career, productivity, and health-related quality-of-life impact due to their child's peanut allergy. Caregivers' perceived risk of outcomes related to their child's peanut allergy (e.g., death or severe reaction) as measured by the Food Allergy Independent Measure independently predicted burden.

Conclusions

Caregivers of children with peanut allergy in the United Kingdom experience health-related quality-of-life, psychosocial, and productivity burden; this study demonstrates the high levels of anxiety reported by both male and female caregivers.

High anxiety and health-related quality of life in families with children with food allergy during coronavirus disease 2019

Background

Food allergy has a known effect on quality of life (QoL), but this has not been extensively studied during the coronavirus disease 2019 pandemic.

Objective

To characterize the levels of anxiety of mothers of children aged 0 to 8 years with food allergy compared with families of children without a food allergy and the health-related QoL among children with food allergy during the coronavirus disease 2019 pandemic.

Methods

In a mixed-methods study, Canadian mothers of children aged 0 to 8 years with (cases) and without (controls) food allergy provided demographic data and completed age-appropriate anxiety questionnaires between April 14, 2020, and April 28, 2020. The cases also provided food allergy-related data and completed the Food Allergy Quality of Life Questionnaire. In-depth interviews were subsequently conducted with purposefully selected cases.

Results

In a total of 580 participants, 5.5% were cases and 94.5% were controls. For mothers of children aged 0 to 1.5 years, anxiety levels did not differ between cases and controls. For mothers of children aged 1.5 to 8 years, anxiety levels were higher in cases vs controls (P < .05). Among the cases, neither overall nor domain-specific Food Allergy Quality of Life Questionnaire scores differed between age groups (0-3 vs 4-7 years), even after adjustment for confounding variables, including childcare during the pandemic. Qualitatively, the following 3 themes were identified: unexpected challenges of food shopping; less food-related food anxiety during the pandemic; and differences and delays in food allergy testing and therapy.

Conclusion

Mothers of children with food allergy reported high anxiety and poor health-related QoL. Yet, qualitatively, day-to-day food allergy management was better during the pandemic.

Evaluation of the measurement properties of the Brazilian version of two quality-of-life questionnaires in food allergy - for children and their parents

OBJECTIVE

To evaluate the psychometric properties of the Brazilian version of health-related quality-of-life questionnaires of children with food allergy and their parents.

METHODS

The translation and cultural adaptation processes were previously performed, according to the method proposed by the World Health Organization. After this stage, the questionnaires were applied to 201 parents of children under 6 years of age with food allergy. The assessment of the psychometric properties included: evaluation of the internal consistency by Cronbach's alpha coefficient; of the reproducibility by the intraclass correlation coefficient between test and retest; and of the construct, using Spearman's correlation coefficient, comparing the obtained scores with those of generic questionnaires that evaluate health-related quality of life.

RESULTS

The means of the obtained scores were 2.44 and 3.35, for the children and their parents, respectively. Cronbach's alpha coefficients were 0.85 and 0.91, respectively, which showed good internal consistency of the tools. The intraclass correlation coefficients between test and retest were 0.87 and 0.84 for children and their parents, respectively, showing good reproducibility for both questionnaires. The correlation between the specific and the generic questionnaires was significant (-0.27 for the children, -0.64 for their parents, p<0.05).

CONCLUSIONS

The specific questionnaires to evaluate the health-related quality of life of children with food allergy and of their parents were satisfactorily validated to be used in Brazil.

Current tools measuring anxiety in parents of food-allergic children are inadequate

BACKGROUND

In the context of food allergy, excessive parental anxiety can be maladaptive and lead to unnecessary restriction of social activities. No validated tool exists to measure food allergy-associated anxiety (FAAA). This study sought to explore factors associated with parental FAAA, determine sensitivity and specificity of using generic state anxiety measure-State-Trait Anxiety Inventory (STAI) versus FAAA, and determine whether validated tools for generalized anxiety or food allergy-specific quality of life (QoL) could be used as surrogates for FAAA.

METHODS

Canadian parents of food-allergic children completed an online survey. Without a validated tool for FAAA, a visual analogue scale was used to assess parent-reported FAAA. Multivariable linear regression was performed with FAAA as the outcome. Sensitivity and specificity analysis of state anxiety vs. FAAA, and factor analysis of state anxiety and QOL, was performed to determine whether these could be used as surrogates for FAAA.

RESULTS

A total of 548 of 1244 parents (44.1%) completed the survey. Factors positively associated with FAAA included parental burden, risk perception, state anxiety, intolerance of uncertainty and perceived severity of child's food allergy; personal/family history of mental health was negatively associated. Sensitivity and specificity of state anxiety were 68.6% and 70.0%. Factor analysis revealed that state anxiety and QOL were correlated (r = 0.54, P < .001) but distinct constructs.

CONCLUSION

Our study identified factors associated with FAAA, and determined that generic anxiety and QOL tools do not accurately categorize parents with self-reported high FAAA. Future research will develop a validated screening tool to help allergists identify anxious parents and provide psychosocial resources.

Food allergens in skincare products marketed for children

BACKGROUND

The application of preparations containing food allergens can cause percutaneous sensitization and provocation. The prevalence of food allergens in children's cosmetics is unknown.

OBJECTIVES

To analyse the prevalence of food allergens in skincare products marketed for children and their association with marketing claims and product price.

METHODS

We reviewed 276 skincare product ingredient labels for the presence of milk, eggs, wheat, soy, oats, tree nuts, peanuts, and sesame.

RESULTS

More than one-third (108; 39.1%) of the products listed at least one allergen. A total of 156 allergens were recorded, of which 65 (41.7%) were almonds, 35 (22.4%) wheat, 24 (15.4%) soy, 16 (10.3%) oats, 13 (8.3%) sesame, 2 (1.3%) milk, and 1 (0.6%) peanuts. Products that claimed to be "natural" or "ecological" were more likely to contain food allergens than those not labelled so (P < .001). The prices were higher for products containing food allergens compared with allergen-free products (P = .028).

CONCLUSIONS

Food allergens are prevalent in children's cosmetics, especially those that claim to be natural or ecological. The most incorporated food allergens are almonds, wheat, and soy. Products containing food allergens cost more than allergen-free ones.

Billing fees for various common allergy tests vary widely across Canada

Background

The prevalence of food allergy in Canada is high and has increased over time. To date, there are no Canadian data on the healthcare costs of visits to allergists.

Methods

We sent an anonymous survey to allergist members of the Canadian Society of Allergy and Clinical Immunology (CSACI) between October and December 2019. Survey questions included demographic information and billing fees for various types of allergy visits and diagnostic testing.

Results

Of 200 allergists who are members of CSACI, 43 allergists responded (21.5% response rate). Billing fees varied widely. The greatest ranges were noted for oral immunotherapy (OIT; both initial consultation [mean $198.70; range $0 to $575] and follow up/build up visits [mean $125.74; range: $0 to $575]). There were significant provincial differences in billing fees, as well as significant billing fee differences between hospital versus community allergists (e.g. oral food challenge [OFC]: $256.38 vs. $134.94, p < 0.01). Billing fees were higher outside of Ontario, with the exception of specific Immunoglubulin E (sIgE) testing and OIT visits.

Conclusions

Greater standardization of billing fees across provinces and between hospital versus community allergy could result in more consistency of billing fees for OFC and OIT across Canada. Further knowledge of exact costs will help inform practice and policy in the diagnosis and management of food allergy.

Therapy competence in delivering a brief cognitive behavioural therapy intervention to reduce maternal anxiety associated with child food allergy

Child food allergy is increasingly prevalent, and caring for such children is associated with elevated parental anxiety. We previously carried out a randomized-controlled trial (RCT) of brief cognitive behavioural therapy (CBT) for parental anxiety associated with child food allergy which found that treatment to be effective. This study describes the manualized brief CBT intervention and assesses the acquisition of competence in delivering this therapy. Three healthcare professionals were trained and supervised in the delivery of brief CBT to 98 mothers of food-allergic children. Competency was assessed using the Revised Cognitive Therapy Scale (CTS-R), with 'competency' defined as a CTS-R score ≥3. All therapists' CTS-R scores increased over time. In the first four months, the mean (SD) CTS-R score was 2.31 (0.56), increasing to 3.14 (0.41) in the second four months (p < .001). Overall, 13/19 (68%) of CBT sessions were rated with a CTS-R score ≥3 in the second four months. After eight months, all therapists were performing CBT at a competent level (17 of the 18 sessions or 94%). The therapists participated in a RCT that reduced maternal anxiety (reported elsewhere). We have shown that therapists not previously trained in CBT can be trained in specific interventions and reach competent levels quickly.

Why Do People Misdiagnose Themselves with Food Hypersensitivity? An Exploration of the Role of Biopsychosocial Factors

Up to 35% of people self-diagnose food allergy or intolerance (food hypersensitivity [FH]), or diagnose it in their child, and self-manage the condition rather than seek a clinical diagnosis. This is much higher than the latest FH prevalence rate, estimated to affect 2–5% of the general population. The actual prevalence rate may be underestimated due to the lack of diagnostic services; however, this can only account for a small proportion of the discrepancy because only a small percentage of self-reported FH can be clinically confirmed. Many people are therefore misdiagnosing their or their child’s symptoms as FH and needlessly removing foods from their or their child’s diet. There are a number of possible reasons for this misdiagnosis, which can be considered from a biopsychosocial perspective. Psychological factors include a confusion over the diagnosis, coincidental pairing of food and symptom, psychological or psychosomatic reactions, and taste aversions. There are also biological mechanisms that have not been fully considered in food allergy research that may be relevant, such as conditioning of the immune system or stress responses. A social context pertains to a greater awareness of FH due to media coverage and changes in food labelling laws. Any of these theories are plausible, but the research to date has a number of methodological issues. Most studies report on small self-selected samples recruited from clinics and there is a lack of general population data. Studies also tend to be cross-sectional, which does not allow cause and effect to be established. Future research needs to include longitudinal designs that incorporate qualitative elements to enable a detailed exploration of reasons why people self and misdiagnose FH.

Why Do People Misdiagnose Themselves with Food Hypersensitivity? An Exploration of the Role of Biopsychosocial Factors

Up to 35% of people self-diagnose food allergy or intolerance (food hypersensitivity [FH]), or diagnose it in their child, and self-manage the condition rather than seek a clinical diagnosis. This is much higher than the latest FH prevalence rate, estimated to affect 2–5% of the general population. The actual prevalence rate may be underestimated due to the lack of diagnostic services; however, this can only account for a small proportion of the discrepancy because only a small percentage of self-reported FH can be clinically confirmed.

Determinant factors of quality of life in adult patients with eosinophilic esophagitis

Background

Eosinophilic esophagitis (EoE) affects health-related quality of life (HRQoL). Data on determinant factors and the influence of dietary interventions are scarce.

Objective

The objective of this article is to evaluate factors influencing HRQoL in adult EoE patients.

Methods

We conducted a multicenter observational, cross-sectional study. A validated Spanish version of the self-administered Adult Eosinophilic Esophagitis Quality of Life (EoE-QoL-A) questionnaire and specific surveys were used. Multiple linear regression was used to identify and quantify determinant factors of HRQoL.

Results

Responses provided by 170 patients were assessed (73.5% male; mean age 33.5 ± 11.4 years). Overall mean score for the EoE-QoL-A index was 1.4 ± 0.8, with no differences between patients on dietary or pharmacological therapy (1.82 ± 0.8 vs. 1.62 ± 0.8; p = 0.132). Disease anxiety showed the highest mean score (2.13 ± 0.9 points), followed by choking anxiety (1.97 ± 1.1); social impact (1.77 ± 1.1), and diet/eating impact (1.68 ± 0.9). Emotional impact had the lowest rating (1.15 ± 0.9), and only with a significantly worse score in patients under dietary restrictions. Recurrent food impaction, a higher educational level, dietary interventions and symptom duration were all independent determinant factors significantly impairing HRQoL. Female gender and empiric elimination diets negatively influenced on diet/eating impact.

Conclusion

Recurrent food impaction, dietary interventions and symptom duration are the most important factors influencing the perception of HRQoL in adults with EoE.
