The purpose of this study is to compare the evolution of self-reported milk allergy in children and adults within the population of Fez-Meknes region, as well as to investigate the consumption of milk and its correlation to milk allergy.
It is a cross-sectional study conducted in Fez-Meknes region between April 2014 and March 2015 basing on a questionnaire completed by 3,068 children and 1,281 adults.
The results showed that food allergy was more reported among children (29.4 per cent) than adults (16.9 per cent). Milk allergy was reported by 5.3 per cent of children and 4.2 per cent of adults. Children reported mostly cutaneous manifestations (64.8 per cent) while adults reported mostly gastrointestinal manifestations (68.5 per cent). The consumption of milk showed a protective effect against the development of milk allergy (p < 0.001).
The consumption of milk was associated significantly with a low rate of milk allergy, especially in adults. However, the pasteurization of milk seemed to be correlated to increase milk sensitivity.
