Always more allergic children? There is no doubt about it. But whose fault is it? Pr Jocelyne Just, head of the Asthma and Allergy Department at Trousseau Hospital in Paris, sifts through the main ideas that circulate on allergies.

These are the most affected children

  • True 90% of allergies occur before the age of 7 years. It is therefore in early childhood that families are most aware of the problem. Nevertheless, allergists are increasingly recording the late onset of allergies in adults. It is therefore not enough to go beyond the age of reason to be quiet.

The smaller the children, the more severe allergy attacks are

  • True and false It is true that allergic manifestations tend to be less strong as children grow up. But this is not the case for all forms of allergies. Food intolerances can be extremely violent and this lasting especially when they are crossed. There are more anaphylactic shocks in adolescence, these famous allergic reactions exacerbated and immediate disrupting the heart rate, the respiratory system and / or digestive. So no question of lowering the guard.

These are the respiratory allergies that have made the most progress

  • False If allergic rhinitis and asthma affect the largest number of patients, their progression would tend to slow down in recent years, as if we were starting to reach a ceiling effect. It is now time for food allergies to develop as quickly as possible. They remain in the minority, but could catch up with others, with a growth rate of 2.5%.

Outdoor pollution is the most dangerous for people at risk

  • False There is a lot of talk about greenhouse gases, CO2 emissions, ozone, and heavy metals in the atmosphere. But what about all that we find in the air of the houses! We are more and more concerned and hunting is now launched against very aggressive pollutants such as formaldehyde present in furniture in agglo, glues, chlorine, indoor fragrances ... But the worst of all pollutants for the children remain tobacco. It alone can trigger asthma and aggravate allergy attacks. Nobody should smoke at home, even at the window!
