Summary: Biparietal diameters (BPD) were determined by ultrasonography on 86 Caucasians and 107 Polynesians at different gestations. Analysis of variance showed a highly significant (p<0.01) difference between groups. At any gestational age, Polynesian fetuses had BPDs 1.89 mm greater than Caucasian fetuses and this fact must be taken into consideration when a single measured value of BPD is being used in the estimation of gestational age. In areas where the obstetrical population comprises different ethnic groups, there is a need for establishing local reference tables by race.
