The results indicate that birth cohorts are composed of two or more subpopulations that are heterogeneous with respect to infant mortality. One subpopulation appears to account for the "normal" process of fetal development, while the other, which accounts for the majority of births at both low and high birth weights, may represent fetuses that were "disturbed… CONTINUE READING
