目的:使用超声对胎儿生物测量的评估提供了准确的妊娠日期和胎儿生长筛查。胎儿生物测定,这是妊娠中期和中期的常见做法,是胎儿形态测量,这包括测量身体不同的解剖部位。这些胎儿尺寸因种族而异。这项研究的目的是通过详细的百分位数表和图表来证明安纳托利亚中部土耳其人口的胎儿生物特征参数测量结果,以更准确地筛选胎儿的生长。
方法:这项横断面研究共对1132例胎儿进行(47%为女孩,和53%的男孩)在妊娠15至40周之间。双顶直径(BPD),头围(HC),腹围(AC),和股骨长度(FL)测量在每个妊娠周以标准化方式进行。在胎头水平面上的丘脑水平测量BPD和HC。HC使用椭圆法测量。在上胎儿腹部的圆形横截面进行AC测量。与股骨骨化的骨干一起测量FL。所有测量均以毫米为单位。
结果:孕妇的平均年龄为27.58(17-43),作为人口统计学数据,平均体重指数为27.68(15.06-50.78)。38.13%的女性第一次29.74%有他们的第二个,在我们的研究中,32.13%的人有三个或更多的妊娠。每个参数的胎儿百分位数数据(BPD,HC,AC,和FL),每周显示为表格和百分位图。在我们的研究与来自不同国家的其他研究之间比较了胎儿第50百分位数的测量结果。Kruskal-Wallis检验结果显示BPD(p=0.827),HC(p=0.808),AC(p=0.846),和FL(p=0.725)值在所有研究中具有统计学相似的平均值。分层聚类分析结果表明,我们对BPD的研究结果,HC,AC,和FL百分位数曲线更接近意大利人口结果。然而,我们的结果与亚洲有统计学差异,尼日利亚,非西班牙裔美国人,和巴西人口的每个不同的参数。
结论:针对特定人群的胎儿生物特征图表的专业化可以确保更准确地评估胎儿的生长速度。在这项研究中,我们显示了安纳托利亚中部土耳其人口的胎儿生物特征百分位表和图形。这些结果可能为产科实践提供有价值的贡献。可以在土耳其的不同地区进行进一步的研究,因此,在全国范围内进行比较是可能的。
OBJECTIVE: The assessment of fetal biometry using ultrasound provides accurate pregnancy dating and also screening of fetal growth. Fetal biometry, which is common practice in the second and third trimesters of pregnancy, is fetal morphometry, which involves taking measurements of the different anatomical body parts. These fetal dimensions vary on ethnicity. The aim of this study is to demonstrate fetal biometric parameters measurement results of the Central Anatolia Turkish population with detailed percentile tables and graphs to screen fetal growth more accurately.
METHODS: This cross-sectional study was performed on a total of 1132 fetuses (47% girl, and 53% boy) between 15 and 40 weeks of gestation. Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) measurements are performed in a standardized manner every gestational week. BPD and HC were measured at the level of the thalami on the horizontal plane of the fetal head. HC was measured using the ellipse method. AC measurement was taken at the circular cross-section of the upper fetal abdomen. FL was measured along with the ossified diaphysis of the femur. All measurements were taken in millimeters.
RESULTS: Pregnant women\'s mean age was 27.58 (17-43), and the mean body mass index was 27.68 (15.06-50.78) as demographic data. 38.13% of women had their first, 29.74% had their second, and 32.13% had three or more gestations within our study. Percentile data of fetuses for each parameter (BPD, HC, AC, and FL) and for each week were shown as tables and percentile graphics. Fetal 50th percentile measurements were compared between our study and other studies from different countries. The Kruskal-Wallis test results showed that BPD (p = 0.827), HC (p = 0.808), AC (p = 0.846), and FL (p = 0.725) values have a statistically similar mean in all studies. Hierarchical cluster analysis results showed that our results for BPD, HC, AC, and FL percentile curves have been found closer to Italian population results. However, our results were statistically different from Asian, Nigerian, non-Hispanic American, and Brazilian populations for each of the different parameters.
CONCLUSIONS: The specialization of fetal biometric charts for a particular population can ensure a more accurate assessment of fetal growth rate. We showed fetal biometric percentile tables and graphics of the Central Anatolian Turkish population in this study. These results may provide a valuable contribution to obstetrical practice. Further studies can be conducted in different regions of Turkiye, thus comparisons could be possible over the country.
