Food hypersensitivity and quality of life

The present article presents an accessible review of research results on food hypersensitivity and quality of life (QoL), including 15 original articles on the subject.

Research on food hypersensitivity and QoL covers children and their parents, adolescents and adults. Several domains of QoL are affected, such as family and social activities, emotional issues and family economy. Food-hypersensitive children are to a large extent limited in their autonomous social activities. Food-allergic adolescents have a higher number of weeks absent from school compared with a control group, and a relatively high percentage of food-allergic young adults do not participate in the labour market. Comorbidity has to be taken into consideration when assessing QoL in food-hypersensitive individuals. Research on gender differences in food hypersensitivity and QoL are scarce.

Although development in this research field has only just begun, it is obvious that food hypersensitivity has a significant impact on individuals' and families' QoL. An important advance is the disease-specific QoL measure instruments that have been created. There is still, however, a need for a more in-depth knowledge as a basis for further development of QoL instruments, and as a basis for societal interventions and family/individual support.
