A team of allergy experts tried to find out how children worldwide are being affected by eczema. Looking at eczema symptoms in nearly half a million 6- to 7-year-olds and 13- to 14-year-olds (combined) in 90 countries, researchers suggest that something — or things — in the environment could be greatly impacting eczema cases among certain ages over the past 5 to 10 years.
But how, exactly? Scientists believe that the tendency to develop eczema is often inherited. And when kids are already genetically predisposed to getting the condition, environmental factors — like pollen, mold, and excessive heat — can certainly help increase their risk. But the recent jump in eczema cases in some countries led the researchers to argue that genes alone can't be to blame since "it is highly unlikely that genetic factors would change in such a short time." That means aspects of kids' environment are probably behind the rise in childhood eczema cases.
The good news: The number of cases seems to be leveling off or decreasing in 13- to 14-year-olds in some countries (such as the United Kingdom and New Zealand) where childhood eczema used to be very common.
The bad news: Eczema in 6- to 7-year-olds keeps significantly increasing in most — especially developing — countries. And some areas (like Southeast Asia, Mexico, Chile, and Kenya) saw a rise in the 13- to 14-year-old group, too.
Unfortunately, the researchers weren't able to pinpoint the exact environmental or genetic risk factors that could be causing the increases. But the study does offer some possible clues about what might be contributing to the increasingly common condition.
