Multivariate study of birth weight and maternal heterozygosity for sickle cell anemia in Bahia, Brazil.
A series of 1,008 newborns of indigent mothers from a mixed Brazilian population was studied with respect to the effect on birth weight of heterozygosity for sickle cell anemia, fetal sex, maternal age, parity, smoking, alcohol consumption and black admixture. Maternal heterozygosity for sickle cell anemia had no measurable effect on birth weight. Significant effects were found for male sex (increase) and smoking (decrease).
