[Ultrasonics and fetal growth in Gabon].

The authors have worked out growth curves for the 3 classical parameters (BPD, HED and Femur) for the Gabonese by studying 870 ultrasound sets of measurements carried out between the 15th and the 40th week of amenorrhoea in normal pregnancies. Comparisons between these curves that have been worked out with those in Europe and the U.S.A. show that there is no difference between them that could be explained by the ecological conditions or the eating habits among other factors.
