Parental Anxiety and Posttraumatic Stress Symptoms in Pediatric Food Allergy

The Natural History and Risk Factors for the Development of Food Allergies in Children and Adults

PURPOSE OF REVIEW

This narrative review explores food allergy prevalence and natural history stratified by life stages, especially in context of evolving knowledge over the last few decades.

RECENT FINDINGS

The prevalence of food allergy remains highest in early childhood with common food triggers being cow's milk, soy, hen's egg, wheat, peanut, tree nuts, sesame, fish, and shellfish. This correlates with certain risk factors especially pertinent in the postnatal period which appear to predispose an individual to developing a food allergy. Some allergies (such as milk and egg) were previously thought to be easily outgrown in early life; however, recent studies suggest increasing rates of persistence of these allergies into young adulthood; the reason behind this is unknown. Despite this, there is also evidence demonstrating that food allergies can be outgrown in adolescents and adults. An understanding of the paradigm shifts in the natural history of food allergy allows clinicians to provide updated, age-appropriate, and tailored advice for patients on the management and prognosis of food allergy.

Psychosocial Impact of Food Allergy on Children and Adults and Practical Interventions

PURPOSE OF REVIEW

IgE- and non-IgE-mediated food allergies are increasing in prevalence in children and adults worldwide. A food allergy diagnosis can be associated with a sense of overwhelm and stress and commonly has a negative impact on quality of life.

RECENT FINDINGS

While there is an increased recognition of the psychosocial effects of food allergy, the current research reflects the experience of mostly White, well-educated wealthier populations. Some studies have now explored the psychosocial impact among other populations; however, further study is needed. It is important that physicians and allied health professionals screen for the potentially negative psychosocial effects of food allergy and provide education to promote safety and self-efficacy at each visit; however, time may be a limiting factor. Numerous validated questionnaires are now available to help assess the psychosocial impact of food allergies. Allergy-friendly foods are typically more expensive, and thus, it is imperative that physicians screen for food insecurity as well. Educational resources should be offered regarding living well with food allergies at each visit. For patients and families experiencing anxiety or food allergy burden that is difficult to manage, referral to a mental health provider should be considered. Resources regarding programs to help accessing safe foods should also be available. Further research is needed among diverse populations focusing on interventions to best support patients and families with food allergy.

Parental anxiety in food allergy: using a cognitive behavioural therapy approach to guide early intervention

Food allergy is a common allergic disease and often coexists with other allergic diseases such as asthma, allergic rhinitis and eczema. Parents of children and young people with food allergy commonly experience stress and anxiety and this can significantly affect their child's mental health. Interventions that incorporate approaches from cognitive behavioural therapy (CBT) can reduce stress and anxiety in parents of children and young people with food allergy and support healthy adjustment and psychological well-being in their children. However, access to psychological services is limited. This article uses reflection on a case study to illustrate the value of taking a CBT-informed intervention approach and to outline the potential role for nurses in its delivery. Research suggests that talking therapies may improve mental health and parenting behaviours in the parents of children and young people with a range of long-term conditions, so this article is also relevant to their care.

Validated anxiety assessments among pediatric patients with peanut allergy on oral immunotherapy

BACKGROUND

Although efficacy, safety, and quality of life measures associated with peanut oral immunotherapy (OIT) have been studied, the relationship between peanut OIT and clinical anxiety has not yet been evaluated. The latter is important to help providers and families have an improved shared medical decision discussion around the benefits of initiating OIT.

OBJECTIVE

To investigate the relationship between undergoing OIT and anxiety in patients with peanut allergy.

METHODS

In this prospective cross-sectional cohort study, using validated and age-appropriate anxiety scales administered with electronic survey questionnaires, we used generalized linear regressions to compare anxiety between patients undergoing OIT and similar patients with peanut allergy but not on OIT (controls).

RESULTS

In the younger cohort (<7 years, n = 80), there was generally a low prevalence of diagnosable anxiety across patients on OIT and controls. In the older cohort (>7 years, n = 125), there was a higher prevalence of anxiety but no clinically meaningful difference between anxiety scores of patients on OIT and controls. In the older cohort, patients with asthma were more likely to have higher mean anxiety scores (P = .04), as were female patients compared with male patients (P = .004). A subanalysis of separation anxiety scores in the older cohort revealed that younger age (7-12 years vs >12 years, P < .001), non-White race (P = .04), and eczema (P = .02) were found to be meaningful predictors of higher scores. A subanalysis of social anxiety on the older cohort pointed toward non-White race as a meaningful predictor of higher scores (P < .02).

CONCLUSION

The clinical implications of these findings suggest that allergists should particularly consider screening children with food allergy for anxiety and anxiety subtypes among patients who are non-White, female, or have asthma.

Management of IgE-mediated food allergy in the 21st century

The 21st century has seen the propulsion of research in the field of food allergy, which has driven real changes in the clinical approach. Allergen immunotherapy has been recommended for the active management of food allergy. Data have shown promising additional methods of treatment, including biologics. Efforts have been devoted to the risk stratification of food allergy and the standardization of the assessment of food-allergic severity. Alternative routes of administration of epinephrine are under investigation to minimize any mechanical issue and the fear of injections. Evidence-based guidelines have been published by the main international societies in the field of anaphylaxis and food allergy management and new updates are in preparation. In the coming years, treatment options that are currently in pre-clinical or early clinical evaluation will hopefully lead to safe and effective disease-modifying therapies for food allergy in clinical practice. The identification of reliable biomarkers and the standardization of definitions and measurement approaches, alongside a shared decision-making with patients and families, will be key for the development of personalized care and to help minimize the substantial burden of food allergy.

Food intolerances in children and adolescents in Switzerland

Adverse food reactions have become an important health concern in pediatrics. There are discrepancies between diagnosed and self-reported food allergies and intolerances, leading to food avoidance with possible psychological and nutritional implications in the latter. There is no data available so far on the number of children and adolescents, who reduce or completely avoid certain foods in their diet. The aim of this study was to determine the prevalence of children and adolescents in the Northwest of Switzerland, who omit foods from their diet because of a self-reported intolerance, as well as the prevalence of children and adolescents who eliminate well-tolerated foods for presumed health reasons. This is a cross-sectional study conducted in the Children's hospitals of Aarau and Basel (Switzerland) and in 4 pediatric private practices. A total of 2036 children and adolescents (54% male and 46% female) between 1 month and 18 years (mean age: 7.4 years) were included, of which 316 (16%) participants reported to avoid foods due to intolerance. Lactose intolerance is the most frequent one. In 55% of all cases, no medical tests had been performed to confirm such an intolerance. Avoiding tolerated foods for presumed health reasons was stated by 251 (12%) participants.  Conclusions: Clinicians should be aware of the high frequency of food avoidance in the pediatric population due to true intolerance, functional diseases, or due to lifestyle reasons. Milk is the most avoided food and half of the affected patients avoid foods without guidance by professional dieticians, therefore risking possible negative impacts on their physical and mental health. Pediatricians should perform further investigations or advise nutritional guidance if an avoidance of foods or specific diets occurs. What is Known: • The prevalence of food intolerances in children and adolescents is unknown. • Eating behavior in children is influenced by the consumption of social media. What is New: • Based on this large cross-sectional study, it was shown that 16% of children and adolescents avoid foods, half of them without any medical advice. • Food avoidance is common among this Swiss cohort of children because of different reasons: lifestyle habits, functional diseases, true intolerances with possible consequences such as micronutrient deficiencies if not properly monitored.

Fear, isolation and the importance of support: A qualitative study of parents' experiences of feeding a child born with esophageal atresia

OBJECTIVE

Feeding and swallowing difficulties in children are increasing due to improved survival rates of children with complex medical conditions. Despite being common complications of esophageal atresia (EA), EA related feeding difficulties have received little attention in research. Establishing positive feeding interactions and practices are important for child health and development, and for parental and child mental health. The current study aimed to investigate the parental experiences of feeding a child born with EA.

METHODS

An international online survey was developed and disseminated to parents of children born with EA, aged 0-12 years, in collaboration with a patient charity for EA. Reflexive Thematic Analysis was used to analyze the qualitative survey responses.

RESULTS

176 participants were included in the qualitative sample from a larger international online survey study, chosen by a process of selective coding. Three themes were constructed during the analysis: 1) Anxiety, trauma and loss; 2) Isolated and unsupported; and 3) Supported. The results indicated that parents of children born with EA experienced significant anxiety related to their child's swallowing and feeding difficulties and traumatic experiences during feeding, and that these led to parents feeling a sense of loss and sadness. It was also found that support, or a lack of support, within parents' social environment might mediate parental experiences of child's feeding difficulties.

CONCLUSIONS

This study highlighted the importance of support for parents of children born with EA, and suggested a need for improved guidance for feeding and swallowing difficulties.
