流行病学、统计学和预防研究部要求对正常胎儿生长的超声标准进行评估，包括种族/民族多样化的妇女、非洲裔美国人、亚洲人、西班牙裔和白人。还需要双胞胎胎儿生长轨迹的数据，特别是绒毛膜。队列研究为“正常胎儿生长国家标准”，共纳入2,400例低危孕妇和600例单胎肥胖孕妇。研究中心包括西北大学、南卡罗来纳州医科大学、加州大学、罗得岛妇女和婴儿医院。获得了585，000个单独的超声图像。收集宫内生长受限新生儿的胎盘进行研究。

The Division of Epidemiology, Statistics, and Prevention Research requests ultrasound standards for normal fetal growth that includes racially/ethnically diverse women, African-American, Asian, Hispanic, and Whites. Data is also needed on fetal growth trajectories for twins, particularly by chorionicity.
