title: A comparison of fetal biparietal diameter measurements between local Chinese and Caucasian populations.
abstract: Since the advent of ultrasound, various workers have published nomograms of the fetal biparietal diameters (BPD). In the Singapore General Hospital, the nomogram established by Campbell and Newman was adopted initially for our multi-racial society. Data from the cross-sectional study of the 1442 BPD measurements of the Chinese fetuses between 17 to 40 weeks showed that the mean BPD values of the Chinese fetuses are lower than the Caucasians. The 2 standard errors of the BPD of the Chinese fetuses does not lie within the 2 standard errors of the BPD of the Caucasian fetuses. The reasons for the difference remain speculative. The presence of the statistical difference between the two means and the 2 standard errors establishes the need for constructing nomograms for our own local reference.
