Seventeen (71%) of these 24 children were exposed while in utero to smoking by a parent or live in relative and also had exposure to household smoke during childhood; seven (29%) had only household smoke exposure in childhood. In the full cohort of 39 children, secondhand smoke exposure correlated inversely with the major stimulator of fibrinolysis, stimulated tissue
