ABSTRACT
18.d.1. D’Souza, S. W., Black, P. M., Williams, N., and Jennison, R. F., Effect of smoking during pregnancy upon the hematological values of cord blood, Br. J. Obstet. Gynaecol., 85, 495—499, 1978. Women who smoked during pregnancy (N = 50, ten cigarettes or more per day) had higher red cell counts, higher hematocrit levels, and higher mean corpuscular hemoglobin values than nonsmokers (N = 75) matched for age and parity. Fetal hemoglobin in cord blood was higher among smokers within social class groups. Smoking may stimulate fetal erythropoeisis.
