Oxidative stress, fetal growth and programming of the metabolic syndrome and cardiovascular disorders
The main objective of MIROS C study is to assess the association between indices of oxidative stress in the mothers and in the newborn and early indicators of programming of 1) cardiovascular disorders and 2) obesity or type 2 diabetes at 1 year of age.
