Good point... Fetal Anthropometric Measures of Our Population

Although sonographic evaluation of the fetus is a widespread practice in Puerto Rico, we lack information of anthropometric values from our normal population as a basis of comparison. In the absence of normative data from our demographic area, a more accurate diagnosis is hindered by the use of reference data from populations of different ethnic backgrounds. Although puertorricans can in no way be considered a distinctive ethnic group, we have different average height and other anthropometric measures as compared to other groups. We report preliminary results from an ongoing study of fetal anthropometric values between 13 and 42 weeks of gestational age collected at our institution. A total of 325 patients have being included in the study up to this date. Exclusion criteria include multiple pregnancy, any maternal chronic illness, gestational diabetes, pregnancy induced hypertension, fetal anomalies detected on ultrasound, any history of smoking or drug use during the pregnancy and non puertorrican birth. We present tables and charts on fetal biparietal parameters (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL), Subtle but significant differences are present in the BPD and FL for our population as compared to reports from populations in the U.S. but not for the AC and HC. These differences are important when problems such as fetal growth impairment or uncertain gestational age are encountered. At Thu, 27 May 1999, Braun, R. Daniel wrote: >

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
