Associations between early life growth trajectories and a range of adult (aged - 25 years) hemostatic factors were assessed in the Barry Caerphilly Growth study (N=517) in South Wales, 1974-1999. Associations of birth weight, birth length, and weight and height velocities during three periods ("immediate" : 0-<5 months, "infant" : 5 months-<1 year 9 months, and "childhood" : 1 year 9 months-5 years) with adult levels of hemostatic factors were assessed. Birth weight was inversely associated with fibrinogen (bêta per 1-unit change in z score=-0.08,95% confidence interval (Cl) : - 0.15, - 0.02). Immediate weight velocity was inversely associated with factor VII (bêta=-1.88,95% Cl : - 3.84,0.09), factor VIII (bêta=-2.58,95% Cl : - 4.07, - 0.45), and von Willebrand factor antigen (bêta=-4.07,95% Cl : - 7.25, - 0.89). Birth length was inversely associated with fibrinogen (bêta=-0.07,95% Cl : - 0.14, - 0.01). Evidence was weaker for an inverse association of immediate height velocity with factor VIII (bêta=-2.16,95% Cl : - 4.62,0.29) and von Willebrand factor antigen (bêta=-2.85,95% Cl : - 6.52,0.81). Childhood height velocity was positively associated with D-dimer (ratio of geometric means=1.11,95% Cl : 1.01,1.23). Results support the view that the immediate postnatal period may be particularly important, possibly through impaired liver development and/or infection in early life, in determining cardiovascular disease risk.
