Investigation of Quality of Life Determinants in Children with Food Allergies

Abstract

<b><i>Background:</i></b> Food allergy (FA) in children impacts their own and their family quality of life (QoL). The association of specific FA factors with the various domains of health-related QoL (HRQL) in children is unclear. <b><i>Objective:</i></b> The aim of this study was to evaluate FA characteristics in primary school children as determinants of components of HRQL. <b><i>Methods:</i></b> Children with FA were recruited from the allergy clinic of a tertiary children’s hospital. Demographic and clinical data were retrieved from their records, and 3 HRQL questionnaires were administered: the FA QoL Questionnaire-Child Form (FAQLQ-CF), the FA independent measure (FAIM), and the Pediatric QoL Questionnaire (PedsQL™). Stepwise multiple linear regression analysis was carried out to investigate the correlation between FA characteristics and the scores on the HRQL scales. Bonferroni correction for multiple comparisons was set at <i>p</i> &#x3c; 0.0002. <b><i>Results:</i></b> Of 172 primary schoolchildren with FA invited to take part, 110 participated (response rate 64%), of whom 83 (75.5%) were male, aged 7.5–12.3 years (mean 10.0 ± 1.4) years. From 38 demographic and clinical characteristics, 10 were excluded on initial data analysis and 28 proceeded to bivariate analysis with the scores on FAQLQ-CF, FAIM, PedsQL™, and their subscales. Most of the 28 showed no correlation with the scores; only 4 were entered into multivariate analysis with FAQLQ-CF and PedsQL™ scores, none of which, finally showed significant association. <b><i>Conclusion:</i></b> The HRQL of children with FA did not depend on gender, age, number, and type of allergen or the characteristics of the most severe allergic reaction.
