Concerning head circumference and biparietal diameter, the results in the usual schedule group were similar to those in the whole population (Tables 3-6), although p-values were generally larger, with smaller sample sizes.
In a cohort of nonsmoking women recruited during the first half of pregnancy, we observed decreased birth weight, decreased head circumference during the second and third trimesters of pregnancy and at birth, and decreased biparietal diameter during pregnancy in association with maternal benzene exposure.
Multiple linear regression analysis was performed with the S100B concentrations as the dependent variable to analyze the influence of various clinical parameters [gestational age, sonographically estimated fetal weight, head circumference and biparietal diameter, transverse cerebellum diameter, abdominal circumference (all automatically calculated at sampling time points using an Aloka SSD-2000 duplex pulsed color Doppler ultrasonograph with built-in software), gender, and maternal age] on the value of S100B.
One potential limitation of the method is that biparietal diameter is affected by fetal position, the ob.
Generally, physicians use a formula combining abdominal circumference with biparietal measurements or femur length to estimate fetal weight, but near term as the baby's head gets deep in the pelvis, sonography may not show the fetal head clearly enough to measure biparietal diameter.
They compared measures of biparietal diameter, head circumference, abdominal circumference, and femur length with published data on mean growth rates in singletons.
