Access to Allergen-Free Food Among Black and White Children with Food Allergy in the FORWARD Study

Food Insecurity Screening in the Allergy/Immunology Clinic: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee

Food insecurity (FI) is defined by the US Department of Agriculture as reduced quality, variety, or desirability of a diet or reduced or disrupted intake of food. There is concern that children with food allergy (FA) may be more likely to be food insecure. The purpose of this project was to investigate the prevalence of FI in the pediatric allergy/immunology population and determine the impact of FA status, race and ethnicity, and geographic food access. An additional goal was to develop a workflow for FI screening in the allergy/immunology clinic setting. Parents of patients were given the validated 2-question Hunger Vital Sign questionnaire in English or Spanish. Those with physician-diagnosed FA were asked a third question about access to allergen-free foods. Families who screened positive for FI received a list of local resources and access to social work assistance. The response rate was 89.1%, with 179 completed surveys. Twenty-three percent of patients screened positive for FI. There was a significant association between race and ethnicity, age, and FI status. FA status and distance from the nearest grocery store were not significantly associated with FI. This study adds to the mounting evidence highlighting the burden of FI in the allergy/immunology population and serves as a call to action for practicing allergists. Efficient FI screening can be accomplished using widely available validated tools. Continued efforts will enable the development of targeted resources to meet this pressing need, with tailored solutions for those on specialized diets.

Social Determinants and Quality of Life in Food Allergy Management and Treatment

Food allergies (FA) significantly affect the quality of life (QOL) and health-related QOL of patients and families managing this chronic condition. Social determinants of health (SDOH) are pivotal nonmedical factors that influence health outcomes and exacerbate disparities in FA diagnosis, treatment, and management. The five domains of SDOH (economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context) shape the lived experiences of individuals with FA. Challenges such as food insecurity, limited access to specialty care, and the high cost of allergen-free foods disproportionately burden under-resourced and marginalized populations, leading to gaps in care and adverse outcomes. This report explores the interplay between SDOH and FA management, focusing on the economic, emotional, and social barriers to optimal care. Furthermore, it highlights the importance of understanding domain-specific QOL, emphasizing tailored interventions to address inequities. Future research must prioritize inclusive representation in clinical trials, innovative strategies to overcome economic and systemic barriers, and tools to measure the unique QOL impacts of FA across diverse populations. Addressing these challenges is critical to promoting health equity and improving outcomes for all individuals affected by FA.

Total Serum IgE in a Cohort of Children With Food Allergy

BACKGROUND

Total serum IgE (TsIgE) has not been examined in children with food allergy.

OBJECTIVE

To evaluate associations of TsIgE with patient, household, environmental, and community-level characteristics among children with food allergy.

METHOD

We used linear mixed-effects models of data from 398 Black and/or African American (B/AA) and White and/or European American (W/EA) children with allergist-diagnosed food allergy from the multicenter, observational cohort FORWARD (Food Allergy Outcomes Related to White and African American Racial Differences); TsIgE (kU/L) was the primary outcome measure.

RESULTS

In univariable analyses of data from all study sites, children's TsIgE was positively associated with older age (P < .001); B/AA race (P < .001); male sex (P = .014); lower household income (P = .005); lower caregiver education (P = .005); higher Area Deprivation Index (P < .001); presence of allergic rhinitis (P < .001), asthma (P < .001), and eczema (P = .024); and a higher number of food allergies (P < .001), but not with tobacco smoke exposure. With covariable adjustment in multivariable analysis, total serum IgE was higher in older versus younger children (P < .001), male versus female children, B/AA versus W/EA children (P < .001), and in children with allergic rhinitis (P = .010), asthma (P < .001), eczema (P = .007), or a higher number of food allergies (P < .001), but not with tobacco smoke exposure or Area Deprivation Index.

CONCLUSIONS

In children with food allergy, age, sex, race, atopic diagnosis, allergic rhinitis, asthma, and eczema are associated with TsIgE. These findings are important when TsIgE values are used in diagnosis and therapies.

Addressing health disparities in food allergy: A Position Statement of the AAAAI Prior Authorization Task Force

Self-reported food allergies (FAs) affect approximately 8% of the US pediatric and approximately 10% of the adult population, which reflects potentially disproportionate increases among ethnically and racially minoritized groups. Multiple gaps and unmet needs exist regarding FA disparities. There is reported evidence of disparities in FA outcomes, and the FA burden may also be disproportionate in low-income families. Low family income has been associated with higher emergency care spending and insecure access to allergen-free food. Pharmacoinequity arises in part as a result of structural racism still experienced by historically marginalized populations today. Historically redlined communities continue to experience greater rates of neighborhood-level air pollution and indoor allergen exposure, lack of transportation to medical appointments, poverty, and lower prescription rates of necessary medications. Clinical research needs racially and ethnically diverse participation to ensure generalizability of research findings and equitable access to medical advances, but race reporting in clinical trials has been historically poor. Addressing health disparities in FA is a priority of clinical care, with professional organizations such as the American Academy of Allergy, Asthma & Immunology having a prominent role to play in mitigating the challenges faced by these individuals. In this position statement we recommend some key steps to address this important issue.

Food Insecurity and Psychosocial Burden in a National Community-Based Sample of Households Managing Food Allergy

BACKGROUND

Experiencing food allergies and food insecurity has been linked to socioeconomic, physical, and mental health-related challenges, but less is known about the intersection of these experiences. This study aims to better understand the impact of food insecurity on food allergy patients and their caregivers, with the intention of informing ongoing efforts to improve screening for food insecurity and mental health concerns and reducing their burden among households managing food allergy.

METHOD

As part of a community needs assessment, a cross-sectional survey was administered to a large, national sample (N=5,940) of US households with at least one food-allergic individual, The Hunger Vital Sign was utilized to assess food insecurity, the Patient Health Questionnaire (PHQ-4) and Food Allergy Independent Measure (FAIM) were leveraged to measure psychosocial outcomes.

RESULTS

Among respondents, 69.9% screened at-risk of food insecurity on the Hunger Vital Sign, while 5.6% reported very low food security. Both adults and children with food allergy (FA) from households at risk for food insecurity were more likely to report FA-related anxiety, anger, loneliness, fear of eating, and bullying victimization than their counterparts from households not at risk of food insecurity (p < .0001 for all). Among these specific experiences, FA-related anxiety was the most common (25.4%/30.1% of children/adults). Perceived risk of food allergy-related fatality was positively associated with food insecurity status.

CONCLUSION

Individuals with food allergies who are concomitantly experiencing food insecurity are at greater risk of a variety of mental health concerns, including those specific to food allergy as well as more general anxiety and depressive symptoms.

Sociodemographic factors linked to food allergy diagnosis among high-risk children with atopic dermatitis

BACKGROUND

Atopic dermatitis (AD) is a known risk factor for the development of food allergy (FA). Prior work has suggested disparities in diagnosis/management of FA in urban populations.

OBJECTIVE

To determine whether socioeconomic conditions, as measured by the area deprivation index and insurance status, or racial/ethnic self-identity was associated with risk of FA diagnosis (DFA), evaluation by an allergist, or objective FA testing among high-risk children with AD.

METHODS

This is a retrospective cohort study of pediatric patients with physician-diagnosed AD who had received primary care at a single urban academic tertiary care center between 2009 and 2022. Statistical analysis in SPSS (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0, Armonk, NY) used χ2, analysis of variance, and logistic regression.

RESULTS

In a total of 3365 pediatric subjects, 41.3% identified as non-Hispanic Black, 33.9% Hispanic, 6.9% Asian, and 14.9% non-Hispanic White. Hispanic children with AD and DFA were significantly less likely to be evaluated by an allergist than White or Asian children (65.9% vs 82.8% and 80.3%, P = .001 and P = .02). Non-Hispanic Black children with AD and DFA were more likely to have no objective FA testing than White children (20.9% vs 12.1%, P = .04). The White and Asian children were more likely to undergo the thorough combination of both blood and skin testing for DFA than Black or Hispanic children (15.5% and 22.4% vs 7.1% and 7.9%, respectively, P = .007, P = .00005, P = .03, P = .0008).

CONCLUSION

Labeling at-risk young children with FA without thorough objective testing can affect their nutrition and quality of life. Barriers to equitable evaluation of DFA should be further investigated and addressed.

Food Insecurity and Health Inequities in Food Allergy

PURPOSE OF REVIEW

The intersection of food insecurity among those with food allergy is a growing public health concern. Both food allergy and food insecurity have profound implications on health, social, and economic outcomes. The interaction of social determinants of health, poverty, racism, housing insecurity, and access to care has direct impact on individuals with food allergy.

RECENT FINDINGS

There is increasing evidence that universal screening for food insecurity is vital in the routine care of patients with food allergy. Individuals with food allergy who are also burdened by food insecurity face unique challenges related to the need to maintain dietary modifications often with expensive specialized diets, which are difficult to access. This may lead to limited dietary options, malnutrition, increased financial burden, and social isolation. While there are available resources and support systems that can assist individuals with food allergies in managing food insecurity, there is an increasing need for advocacy and inclusivity in policy frameworks involving multiple stakeholders. Multi-sector efforts involving healthcare providers and advocacy and government agencies are necessary to support policy changes that protect the rights and well-being of individuals affected by food allergy and food insecurity. By increasing awareness, improving access to safe, affordable, allergen-free food, and advocating for policy change, we can work toward ensuring universal access to safe, nutritious food for all individuals, regardless of their food allergy status or socioeconomic background.

Addressing Health Equity in Food Allergy

Social determinants of health can lead to poor health outcomes for food-allergic patients, including limited access to allergen-free foods and specialty care. Housing and transportation limitations can worsen social factors including food insecurity, poor early food introduction, increased reactivity to foods, lower tertiary/allergy care utilization, and increased emergency department utilization. A key component of addressing health equity involves valuing all people with sustained, focused efforts to address social determinants of health. In this clinical commentary, we discuss the current state of heath equity for food-allergic patients, highlighting the disparities in emergency care, food allergy prevention, and food insecurity. Solutions to improve health equity through clinical practice are proposed. Currently available funding opportunities through the National Institutes of Health for health equity initiatives are outlined. Gaps in health equity for food-allergic patients include the lack of documented successful implementation of effective solutions to food insecurity, poor early food introduction uptake, poor access to specialist care, and unequal distribution of educational resources. The availability of research funding and legislative policies supporting access to food and education bolster the impetus to move toward health equity for 20 million people in the United States with food allergy.

Identifying Children at Risk of Growth and Nutrient Deficiencies in the Food Allergy Clinic

BACKGROUND

Food allergies affect growth in children by decreasing the availability of nutrients through decreased dietary intake, increased dietary needs, food-medication interactions, and psychosocial burden. Guidelines on food allergy management frequently recommend nutrition counseling and growth monitoring of children with food allergies.

OBJECTIVE

To provide clear guidance for clinicians to identify children with food allergies who are at nutritional risk and ensure prompt intervention.

METHODS

We provide a narrative review summarizing information from national and international guidelines, retrospective studies, population studies, review articles, case reports, and case series to identify those with food allergy at greatest nutritional risk, determine the impact of nutritional interventions on growth, and develop guidance for risk reduction in children with food allergies.

RESULTS

Children with food allergies are at increased risk of nutritional deficiencies and poor growth. Nutritional assessment and intervention can improve outcomes. Identifying poor growth is an important step in the nutrition assessment. Therefore, growth should be assessed at each allergy evaluation. Interventions to ensure adequate dietary intake for growth include appropriately prescribed elimination diets, breast-feeding support and assessment, supplemental formula, vitamin and/or mineral supplementation, appropriate milk substitutes, and timely introduction of nutrient-dense complementary foods. Access to foods of appropriate nutritional value is an ongoing concern.

CONCLUSION

Nutrition intervention or referral to registered dietitian nutritionists with additional training and/or experience in food allergy may result in improved growth and nutrition outcomes.

Food insecurity and allergic diseases: A call to collective action

Food security encompassess the concept of access by all people at all times to enough food for an active, healthy life. Conversely, food insecurity (FI) refers to household-level economic and social conditions of limited or uncertain access to adequate food. FI is a key social determinant of health that can negatively affect nutrition and health outcomes, as it is estimated that 10.2% of the US population meets criteria for FI. Recognizing the impact of FI on our patients and families is critical to promote health equity and optimize health outcomes. This review focuses on FI and allergic disease from the perspective of key multisector stakeholders within the field of allergy and immunology as well as from the larger health care arena, highlighting key resources and initiatives important to patients. Collectively, as specialists in allergy and immunology, and within the medical field more broadly, we must leverage our unique roles as we interface with patients and families and serve as committed advocates for change. Developing innovative strategies to promote health equity can provide a pathway forward for all children, adults, and families to gain access to healthy, nutritious food as part of their routine lifestyle. This is a call to action.

Impact of socioeconomic factors on allergic diseases

Allergic and immunologic conditions, including asthma, food allergy, atopic dermatitis, and allergic rhinitis, are among the most common chronic conditions in children and adolescents that often last into adulthood. Although rare, inborn errors of immunity are life-altering and potentially fatal if unrecognized or untreated. Thus, allergic and immunologic conditions are both medical and public health issues that are profoundly affected by socioeconomic factors. Recently, studies have highlighted societal issues to evaluate factors at multiple levels that contribute to health inequities and the potential steps toward closing those gaps. Socioeconomic disparities can influence all aspects of care, including health care access and quality, diagnosis, management, education, and disease prevalence and outcomes. Ongoing research, engagement, and deliberate investment of resources by relevant stakeholders and advocacy approaches are needed to identify and address the impact of socioeconomics on health care disparities and outcomes among patients with allergic and immunologic diseases.

Barriers to Timely Diagnosis of Eosinophilic Gastrointestinal Diseases

Although eosinophilic gastrointestinal diseases, including eosinophilic esophagitis, have been described over the past 2 to 3 decades, barriers to diagnosis and treatment are common and compounded by issues related to social determinants of health, race, ethnicity, and access to care. These barriers contribute to delays in diagnosis, resulting in persistent inflammation in the gastrointestinal tract, which can have significant consequences, including fibrostenotic complications in adults, failure to thrive in children, and decreased quality of life in all affected patients. In this commentary, we summarize gaps in knowledge regarding the epidemiology of eosinophilic gastrointestinal diseases, highlight barriers to diagnosis, discuss potential approaches based on best practices in other atopic and chronic gastrointestinal diseases, and provide recommendations for reducing barriers to timely diagnosis of eosinophilic gastrointestinal diseases in underserved populations.

Food insecurity in children and adults with food allergies

Food allergy is a substantial public health concern associated with risk of severe or potentially life-threatening reactions and requiring life-altering changes in dietary habits. This increasingly prevalent health concern is associated with adverse medical, nutritional, psychosocial, and economic effects on the estimated 32 million affected individuals in the United States. Management of food allergy requires life-altering dietary modifications and constant vigilance to avoid implicated allergens to minimize the risk of anaphylaxis, which can lead to considerable anxiety and reduced quality of life. Specialized diets are expensive and often difficult to access, particularly for low-income and minority individuals with food allergy. The overlap of food insecurity with diet-treated illnesses further increases the burden on patients with food allergies and their families, with overall rates of food insecurity increasing substantially during the coronavirus disease 2019 pandemic. Universal screening to identify food insecure households and connect them with appropriate resources is a critical step in addressing unmet needs at the individual and family level. At the systems level, integrated advocacy approaches addressing the complex interplay between multiple societal issues such as poverty, systemic racism, wage inequality, housing insecurity, lack of transportation, and other social determinants of health are vital to ensure access to safe, healthy, nutritionally complete options for patients with food allergies and their families.

Health disparities in pediatric food allergy

OBJECTIVE

To review the current literature regarding the health disparities in the prevalence, diagnosis, and management of pediatric food allergy and discuss possible interventions.

DATA SOURCES

Literature search of PubMed and Google Scholar databases regarding pediatric food allergy and health disparities.

STUDY SELECTIONS

Original research articles, reviews, and guidelines on health disparities in pediatric food allergy were included in this review.

RESULTS

The overall prevalence of food allergy appears to be increasing and disproportionately affecting minority groups. Racial and socioeconomic disparities are evident across all aspects of food allergy care: diagnosis, prevention, acute management (eg, access to epinephrine autoinjectors, visits to emergency department), and long-term management (eg, oral immunotherapy). Children of minority populations and those of low socioeconomic status are at a greater risk of food insecurity, which is further exacerbated by the high cost of allergen-free foods and limited support from food assistance programs.

CONCLUSION

Racial, ethnic, and socioeconomic disparities in food allergy among children in the United States are evident and negatively affect the outcomes of children with food allergies. Active efforts to decrease racial and socioeconomic disparities, through education, research, and advocacy, will be important to help improve health outcomes in food allergy for all children, regardless of their race, ethnicity, or socioeconomic status.
