Even if morbidity and mortality from food allergy in children are generally low, strong evidence testifies that food allergy has a relevant impact on psychological distress and QoL of children and adolescents, as well as their families [3].
Since recently health related QoL has been recognized as an important outcome measure in clinical studies [18], new instruments for assessing QoL in food allergic children have been developed and validated in order to provide further insights into the problems these children encounter [3].
However, even if it is impossible to disregard that eating is strongly related with familial, social and group activities, the effects of food allergy on nutritional approach of patients and their families are still relatively under-explored.
The main objective of the present survey was verifying in a sample of mother-child pairs the impact of food allergy on family’s attitudes towards food, with implications for social life. According to our results, children food allergy seems to strongly influence the family eating habits of a portion of respondents: nearly 10% of the participants’ families decided to completely exclude food allergens from their home: this means that all family members follow the restricted diet; this is a “drastic” measure finalized to guarantee a safe environment to the allergic child, eliminating accidental ingestions and contaminations. However, excluding the offending food from the domestic setting could prevent the child from being trained to avoid allergens. In fact, families that bring the allergen into the home implement strategies to correctly discriminate between safe and not safe foods and have the opportunity to teach the child how to manage avoidance [8].
Moreover, even if most of the participants share meals with family or peers, about one sixth of the interviewed patients consumed their meals separately from the other family members and/or did not attend school canteens to minimize the risk of contaminations. This obviously can have an impact on social life [19, 20]. This happens, above all, concerning attendance to social occasions involving foods: more than one fourth of the participants asserted they attend parties rarely or never. Particularly, in our sample, the increasing of the number of excluded foods was related to a decreasing on the attendance to social events. The result is in line with literature data reporting a significant disruption in family social events [3, 7]: many parents would rather reduce the risk and concern induced by social activities by avoiding them altogether [13] and a number of parents report preventing their child from attending parties and school trips [21]. Interestingly the mothers’ trait anxiety T-score was found to impact on the attendance to social events involving foods, a moderate score, rather than a low score, being linked to a decreasing in joining social gathering.
The participants (older than 6 years old) who declared to attend parties always or sometimes reported to usually use two main strategies to cope with the burden of food allergy: many of them carefully check labels to assure the avoidance of allergens from foods, confirming how label reading represents the keystone of food allergy management [8, 22, 23]. As an alternative, children bring foods from home. Only in a very small number of cases participants reported to usually not assume any kind of food when attending social events.
A varied nutrient intake provides the opportunity for an adequate nutrient intake balance reducing malnutrition risks [24, 25]. When asked about interest in tasting new foods and monotony of the diet, the participants showed a medium-level score and reported “strict avoidance” and “low curiosity about food” as the main causes of repetitive diet. This could be linked to the fact that children suffering from food allergy sometimes develop disordered eating or become withdrawn and fearful about food [10, 11, 26]. The avoidance of allergen traces is often a necessary strategy to stay away from the risk of reactions, however, it is found to be a heavy burden for patients and their families. A better allergy-specific QoL in mothers and their children who report eating products labelled “may contain nuts” than those who strictly avoided all nuts was reported [5]. In addition, many families reported that the most significant obstacle which prevents them leading a normal life is the widespread use of “allergen traces” labelling on pre-packed foods [23]. Other reasons reported in the present study for monotonous diet are, in fact, a limited choice of food industry safe products and difficulties in making traditional recipes.
The monotony of the diet was resulted influenced by the child and mother age in an opposite way. The more the mother age raised the more the monotony of feeding enhanced. Avoidance of the allergen requires mothers to learn to adapt recipes and make appropriate substitutions [8] so that more than 60% of caregivers reported that food allergy significantly affected meal preparation [13]. It could be that older mothers have more difficulties in making traditional recipes using alternative ingredients or in finding new adequate recipes. To the contrary, an increasing of the child age was linked to a decreasing on the repetitiveness of the diet: it could reflect children overcoming some food allergies [1] extend their diet, or simply change in dealing with food over time.
Similarly to what observed for the attendance to social events, the increasing of the number of excluded foods was related to an augment of the repetitiveness of the diet, confirming that the number of food allergies had a significant negative impact on family activities [13, 27] and on the perceived overall health-related QoL [7].
Even if not as a primary intent, this study investigated also the influence of mothers’ trait anxiety on the food approach and management. Most of the patients’ mothers (n = 114; 91.9%) reported a moderate or low mean score when compared with the Italian normative data. At the contrary, some studies reported higher trait-anxiety levels in food allergic mothers than in norm means [5, 15]. A possible explanation could be that all the participants of the present study attended a Referral Centre for Food Allergy Diagnosis and Treatment, where they received adequate information and support about the disease: this could have influenced mothers’ level of anxiety; therefore, caution is needed in generalizing these results. The mothers’ trait anxiety T-score was found to impact on the attendance to social events involving foods: a moderate score, rather than a low score, is linked to a decreasing in joining social gathering. A phenomenological study underlined how the feeling of “living with risk” was present in food allergic children’s mothers and it was associated to an emerging feeling of “living with fear” that could influence everyday life [28]. A link between mother’s wellbeing and “social” managing of food allergy was found; nevertheless further researches are needed to understand the underlying psychological mechanisms.
This study investigated the impact of food allergy on nutritional behavior and attitudes of the patients and their families, exploring the influence of some variables in their way of dealing with the disease. Gender and clinical history seemed to not influence the findings.
As far as we know, this is the first study focusing specifically on the issue. Our results underline the impact of food allergy in reducing interest about food and in influencing patients’ approach to social life: these findings stress in fact the importance of supporting families in managing psychosocial aspect of food avoidance and in arousing curiosity in children, suggesting recipes for a varied and stimulating diet.
