The COVID-19 pandemic continues to impact the mental health of children and youth worldwide, particularly for those with chronic physical conditions 1 and socioeconomic adversity 2 . For children and youth with food allergies (FA), the early COVID-19 pandemic led to immediate changes to allergy-related services 3 ; emergency department visits for anaphylaxis also decreased 4 . Youth whose parents report negative impacts of COVID-19 have also reported poorer well-being, affected by difficulties accessing "safe" foods and health services 5 .

Moderate anxiety in parents of children with FA is generally adaptive given risks of allergen exposure. However, excess anxiety can lead to increased parental burden and impaired healthrelated quality of life 6 . FA-specific anxiety (FAA) includes emotional, cognitive, behavioural, and physical domains; while associated with generalized anxietyin which worries about a number of events or activities are difficult to controlit is a distinct construct 7 . To our knowledge, there have been no analyses of impacts of the pandemic on parental FAA and implications for family support. In this study, we sought to describe parental experiences of FAA during the COVID-19 pandemic, and to evaluate the relationship between general anxiety symptoms and FAA. This was a cross-sectional online survey of Canadian parents of children and youth with FA completed in May-June 2020, at which time in-person medical visits for non-urgent care were limited and most schools had transitioned to a virtual model. A survey link was distributed electronically through national and local patient advocacy groups and by public lectures. Survey components included demographic information, allergy history, and the GAD-7, a measure of generalized anxiety symptoms 8 . Also queried were current and pre-COVID-19 aspects of FAA using a 28-item questionnaire undergoing validation, the Impairment Measure for Parental food Allergy-related Anxiety and Coping Tool, IMPAACT 7 . This study was approved by the University of British Columbia Children's and Women's Research Ethics Board.

A convergent parallel mixed methods design was employed to allow for triangulation of results and illustration/elaboration of quantitative results with qualitative findings 9 . Associations were evaluated with bivariate Spearman correlations. Significance was determined by two-tailed t-test or chi-squared test, accounting for multiple comparisons using the Benjamini-Hochberg correction with a false discovery rate of 0.05. Predictors of self-reported change in FAA with COVID-19 on a 5-point scale from 1 (decreased greatly) to 5 (increased greatly) were determined by ordinal regression modelling. Mean±SD of continuous variables, median (IQR) of ordinal variables, and 95% confidence intervals for odds ratios (OR) are reported. Qualitative content analysis using an inductive approach was used to describe open-ended responses 10 . Two researchers independently coded responses, with differences resolved through discussion. Codes were grouped into categories with corresponding frequencies, then further grouped into themes.

Qualitative and quantitative analyses were conducted independently with results synthesized at the point of integration in the interpretation.

Of the 383 parents who consented to participate, 293 completed the FAA questionnaire (77% completion rate). The majority of respondents lived in Ontario (46%), British Columbia (28%), Alberta (8%), or Manitoba (5%). Mean age was 43.3±7.0 (range 27-64). 92% of respondents were mothers, reporting a greater share of FA management responsibility than fathers (79±18% versus 58%±23%, p<0.0005). Post-secondary training had been completed by 65% while 30% had a postgraduate or professional degree. The majority (56%) reported household income of $100,000 per year or more. Half (49%) reported that only essential services and businesses were operating in their region and 79% that schools were either completely closed or virtual only (with the remaining in-person or hybrid). Other measures included social distancing and limitations on gatherings. Most respondents had one (85%) or two (14%) children with FA, with mean age 10.4±5.6 years, on average 8.3±5.3 years from diagnosis. Parent-reported biological sex was fairly evenly distributed between males (56%) and females (44%). Most respondents perceived their child's FA as severe (79%) rather than mild or moderate, and 70% reported a history of anaphylaxis. The most frequently reported allergen was peanuts (80%) followed by tree nuts (56%), eggs (34%), milk (27%), sesame (20%), soy (10%), shellfish (9%), fish (8%), wheat (7%), mustard (2%), and others (21%). With respect to multiple FAs, 32% of respondents reported their child had to avoid 1-2 foods; 31% 3-6 foods; 10% 7-9 foods; and 28% 10 or more.

Approximately one third (36%) reported a history of asthma.

With respect to overall stress and anxiety, 67% of respondents reported an increase that they attributed to COVID-19, whereas only 28% reported increased FAA due to COVID-19 (p<0.0005). Most respondents reported unchanged (30%) or decreased (42%) FAA attributable to COVID-19, even among those with increased overall anxiety (in whom FAA was decreased or unchanged in 35% and 24%, respectively). Significant predictors of parent-reported increased FAA due to COVID-19 were increased overall anxiety (OR=3. With respect to aspects of FAA measured by IMPAACT 7 , participants reported that the pandemic was associated with a decrease in all FAA dimensions, with the greatest reductions related to worries about unfamiliar places and management of allergic reactions by other caregivers. Compared to before COVID-19, parents reported improvement in all items and reduced interference with functioning in all domains, except for worry about finding specific "safe" foods at the grocery store. Current versus retrospective (pre-COVID-19) report of anxietyrelated symptoms increased slightly based on GAD-7 total score (6.2±5.7 versus 5.4±4.9, d=0.15, p=0.011), less than the reported minimal clinically important difference (MCID) of 4 8 .

On the other hand, current versus retrospective IMPAACT score was significantly lower (89±37 versus 105±35, d=-0.44, p<0.0005). The MCID for IMPAACT has not yet been determined.

Qualitative responses included both positive and negative impacts as described and integrated with quantitative findings in Table 1 .

This study has several limitations, including sampling bias associated with online surveys and lack of demographic representativeness given high education and income levels. Data on racialized identity were not collected and must be addressed by future work, together with Other behaviours including avoidance of travelling, social activities, leaving the child in the care of others, and checking on the child were also significantly reduced during COVID-19. Integration d : Increased time at home and in the care of parents concomitant with fewer social activities allowed for increased parental control over potential allergen exposures (QUAL), which was the most frequently reported mechanism to explain reduced worry about allergic reactions (QUAL, QUAN) and fewer allergy-related avoidance behaviours (QUAN). Shared experience of "being cautious"

Relief regarding increased hygiene and hope that this will also the reduce risk of allergen crosscontamination; fewer social situations requiring explanation, decisions, or limit-setting.

"…no birthday parties for which I need to be 'that mom' who sends her kid with their own cupcake and has to have a conversation with the hosting family." "Covid -19 is a taste of the anaphylaxis 'lifestyle' for people who don't understand the severity of food allergies. You have to avoid, be aware, wash hands, anxieties are created, not everyone sees it the same."

Overall impact of FAA on activities/stress including relationships with others and work/leisure was decreased during COVID-19 versus retrospective report (d=1.2, p<0.001 for both).

Integration: Decreased impact of FAA on relationships and daily activities/stress (QUAN) was consistent with participants' reports of less frequently needing to explain themselves and their child's restrictions to others (QUAL). This was largely due to normalized/required avoidance of physical interaction associated with public health restrictions, and perceived increased understanding of their situation due to a now shared experience of environmental risk (QUAL). Decreased worry about allergic reactions during COVID-19 (QUAN) may also be partially explained by the perception that increased attention to hygiene/cleaning would protect from allergen cross-contamination (QUAL). Difficulty finding scarce resources Usual safe foods out of stock in grocery stores; unknown ingredients in alternate foods; limited epinephrine autoinjector availability.

"The most difficult part is when all my son's 'safe foods' are out of stock. It isn't easy to just grab whatever is left on the shelves, as they usually have a 'may contain'' label." "I find it hard when the stores are stocked out of the safe foods and ingredients... These products and brands have been out of stock in our stores for months, so that has been difficult and very stressful. We have had to stockpile some flours and yeasts and ingredients when we find them to avoid running out…" "We can't get certain foods we usually get because we are using a delivery service."

"This is what causes the biggest stress -not being able to find suitable food.

"The grocery stores do not want us to touch the product on the shelves-but if I can't get a product I know is safe, I'm not buying it, and that means I need to read the ingredients. My heart really goes out to the 33 (26) All domains of FAA queried were rated as less concerning during COVID-19 except for worry about finding "safe" foods at the grocery store, which was significantly increased (d=1.373, p=0.001). Non-nut allergies predicted increased FAA attributed to COVID-19.

families who are managing more than just a tree nut / peanut allergy."

"Then I went to replace used epi pens and there were none to be had."

Integration: Not being able to find specific "safe" (allergen-free) foods at the grocery store was the only aspect of FAA that increased overall with COVID-19 (QUAN); this was associated with potential and actual shortages of regular food products and stress associated with needing to carefully read labels of unknown products, particularly for children with non-nut allergies (QUAL). Concerns about food availability may partially explain why parents of children with non-nut allergies were more likely to report increased FAA attributable to the COVID-19 pandemic (QUAN). Interactions between FA and COVID-19 health risks

Increased risk of infection in the Emergency Room (ER) if care is needed for anaphylaxis; concern about unknown direct effects of COVID-19 infection and interactions with asthma or allergies in children with FA.

"Initially when things shut down there was great fear about a possible reaction and having to go to ER."

"…I worry about her having a severe reaction and needing to go to the hospital, possibly increasing her risk of getting COVID-19." "I know covid is more survivable than anaphylaxis, so I am really working on separating those in my mind to calm down…" "Since food allergies are often linked to asthma, I do worry about my daughter who has had to use a puffer on many occasions..." "I also don't know how COVID impacts allergy kids, so that increases my stress.."

Prior ER visits was a significant predictor of parent-reported increased FAA attributed to COVID-19. The magnitude of reduction in hesitation about food introduction for younger children and avoidance of foods beyond identified allergens were two aspects of FAA queried did not decrease to the same extent as other FAA-related items during the COVID-19 pandemic.

Integration: Fear of the consequences of having to attend hospitalin particular the risk of acquiring COVID-19 in the Emergency Room (ER; QUAL)may explain why previous ER visits were associated with parent report of increased FAA attributable to COVID-19 (QUAN). Concerns about potential allergic reactions (and therefore ER visits) in response to new foods or when introducing foods for other children did not decline as much as other aspects of FAA with COVID-19 (QUAN), perhaps because of fear of the risks involved in seeking medical care (QUAL) or concerns it would not be available (see "Unavailable medical care" below). Anticipation of going back to "normal" Increased anxiety returning to restaurants with lifting of restrictions; uncertainty regarding transitions to new schools during COVID-19.

"But now that businesses are beginning to reopen since Covid has slowed down in our region, the concern is beginning to rise again since we may/will start to go out of our home again. My 14-year-old has expressed more risky behaviour…" "Fewer trips to restaurants has increased my child's anxiety about eating out, even in restaurants we worked hard to make her feel safe at previously." 5 (4) No direct quantitative data; this category reflects parental recognition of reduced risk of allergen exposure and associated stressors during COVID-19, with the potential to increase as public health restrictions and associated psychosocial circumstances change.

Integration: Not applicable; major QUAL finding only. This category represents recognition by parents of the potential perpetuating role of avoidance in FAA and possible impacts on both FA-related distress and family functioning with loosening of public health restrictions and increased potential exposures. Decreased support Unavailable medical care Decreased availability of pediatric allergist assessment, food challenges, and oral immunotherapy (OIT); possibly limited availability of emergency services in the event of a severe reaction.

"We are on the waitlist for OIT to begin… & fear that this pandemic has delayed the chances of accessing it indefinitely." "My baby was just diagnosed by our doctor but we are doing a video call with the allergist instead of going to his office. I am also worried that testing won't happen or that more tests than normal will happen in one appointment to reduce the amount of appointments." "Worry if he was to have an anaphylactic reaction, we would not be able to get him the help we need 7 (6) See "Interactions between FA and COVID-19 health risks" above.

in a timely manner."

Integration: In addition to the risk of COVID-19 infection (see "Interacting health risks"), worry about lack of available emergency care (QUAL) may further explain why previous ER visits were associated with increased FAA during COVID-19 (QUAL). Concerns regarding lack of FA assessment and treatment related to reduced in-person medical care were restricted to QUAL findings. Lack of FA awareness and accommodation Sense of social isolation and minimal understanding by others of challenges associated with managing FA, including shopping during the pandemic; concern regarding preoccupation of others (including restaurant staff) with COVID-19 to neglect of FA considerations.

"Grocery shopping is more difficult. I need time to read the labels and always feel rushed because people are impatiently waiting to come down the grocery aisles behind me."

"It begs the question if, just like seniors had special hours for grocery shopping at some point -people with food allergies should be prioritized, as their choices of food are limited." "…are gloves changed ?? is cross contamination an issue now?? the workers are stressed in the restaurants -are they also having trouble keeping it all straight -are they rushing not to touch things -are their glasses fogging up -so many issues" 6 (5) See "Difficulty finding scarce resources" above.

Integration: Despite an overall decrease in FAA and perception of associated risk (QUAN), some respondents were more concerned that the predominant focus on COVID-19 risk would lead to more carelessness in handling of allergens (QUAL). Some respondents also suggested that specific accommodations were needed for grocery shopping due to store rules about not touching products (thus making label-reading difficult) and described stress related to other shoppers' impatience in this context (QUAL), consistent with increased worry about finding "safe" foods at the grocery store (QUAN). a Implicit or explicit impact of responses within category on food allergy-specific anxiety (FAA). b n=126 total free-text responses (43% of 293 participants); categories comprising 5 or more responses are shown. c Cohen's d calculated using the sample standard deviation of the mean difference/reduction for each item during COVID-19 compared to retrospective report prior to the pandemic (negative values indicate higher/worsening score during COVID-19 while positive values suggest improvement). Note that frequency/agreement was rated on a 7-point Likert scale for each item as described in the text and previously 7 . d Integration provides a summary of convergent quantitative (QUAL) and qualitative (QUAL) findings and use of qualitative data for elaboration/illustration.
