Little is known about the loss of productive workforce or healthy life time due to food allergy or food intolerance. One aim of the BELANA trial (Burdens and Expenses of Living as Adult with Nutrition based Allergy or Intolerance) was to investigate the healthy time lost for work or spare time due to corresponding disease.
314 study participants (≥18) with self-reported food allergies or intolerances were recruited in 2009 by the German Allergy and Asthma Association (DAAB). 247 completed the BELANA questionnaire four times within four-month intervals. The participants had to state whether they were unable to fulfil their daily tasks at work, at home, or at school due to problems with their food allergy or intolerance. Furthermore, they had to indicate the number of affected days.
The group of self-reported food allergy and food intolerance sufferers that complain about the loss of healthy time due to their illness is larger as compared to the group that does not experience this kind of burden. The high number of lost healthy days indicates that the data might be biased towards severe cases of food allergy and intolerance. This will need further investigation through cross-validation with other questionnaire items.
