A total of 3795 measurements, with a mean of eight per woman, were obtained every three weeks during the second and third trimester. Biparietal, occipitofrontal, abdominal transverse and anteroposterior diameters (combined into mean abdominal diameter), as well as femur and humerus length were measured. The data were computerised and grouped into 12 two-week periods for each of which the mean examination day was calculated. Multiple regression analysis was applied to fit the data to mathematical equations. Third degree polynomials showed optimal fit to the bone measurements, but second degree to the abdominal measures. The equations gave values for the bone measurements very similar to those previously described from other Nordic countries, but because of larger size of the material and less accurate cycle dating, the dispersion of values was larger. Mean abdominal values were systematically about 7% lower, which probably was due to differences in measurement technique. This must be accounted for by use of an appropriate correction factor when the measurements are used to estimate fetal weight. Comparative data on fetal growth in the Nordic countries and nomograms for growth of Icelandic fetuses are presented. Framvirk athugun á fósturvexti íslenskra einbura var gerð með mælingum í 94 heilbrigðum konum á öðrum og þriðja meðgönguþriðjungi. Allar konurnar gátu dagsett fyrsta dag síðustu tíða nákvæmlega og höfðu reglubundinn tíðahring. Mælingar voru gerðar á þriggja vikna fresti á höfuðmálum, 1) þvermáli (biparietal diameter (BPD)) og 2) fram-aftur máli (occipito-frontal diameter (OFD)), lengd lærleggjar og upparmsleggjar og tveimur þvermálum búks. ...
