The present proposal contains three separate research questions with a different background that both will be an extension of the Wheezing Illnesses Study Leidsche Rijn (WHISTLER).
Study 1: The relations between early childhood obesity and arterial disease.
Study 2: Low lung function in early childhood: nature or nurture?
Study 3: The relation between Diabetes type I during pregnancy and vascular characteristics in the offspring.

Study 1: The purpose of this study is to gain more insight in the characteristics that are related to vascular damage at a young age, and particularly to detect if obesity is related to vascular damage (and thus the risk of cardiovascular disease in…
