SUMMARY
To describe pattems and limits of intrauterine
growth in the Icelandic population a longitudinal
ultrasound study was carried out in 94 healthy
women, all with regular 28±2day cycles and able
to securely date the first 'day of their last menstrual
period. 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.
