Screening for the small for dates fetus using ultrasound measurement of the fetal abdominal circumference resulted in a significantly increased rate of diagnosis compared with clinical examination. However, when the perinatal mortality and morbidity amongst infants with a birthweight less than the 10th percentile for gestation in the screened group was compared with that of similar infants in a nonscreened groups who attended the same antenatal clinic but who either booked or were referred late, there was no significant difference.
与临床检查相比，使用超声测量胎儿腹围来筛查小于孕周胎儿，其诊断率显著提高。然而，将筛查组中出生体重低于孕周第10百分位数的婴儿的围产期死亡率和发病率，与在同一家产前诊所就诊但要么预约过晚要么转诊过晚的未筛查组中类似婴儿的围产期死亡率和发病率进行比较时，没有显著差异。
