What is the MAS-Study?

Funded by the Federal Ministry of Education and Research, the long-term study MAS started in 1990. The aim was to investigate the natural course of allergic diseases from birth to adulthood. It is also of interest to us to find out why some people do not develop allergies but possibly other chronic diseases. For this purpose, a sample of 1,314 newborns from the year 1990 and their parents was selected in large clinics in Berlin (2 clinics), Munich, Freiburg, Mainz and Dusseldorf. In addition to allergic persons, especially non-allergic study participants for MAS are of extreme importance, since they represent our so-called control group. We compare the two groups to find out what factors cause some people to develop an allergy - which in some cases even disappears, but in others it persists into adulthood - and which factors in others protect against asthma and other allergic diseases.
Our last follow-up was completed when the participants were 20 years old. More than 70% of the participants had participated again.

Many thanks to all involved and their families!
