Ninety-four high-risk pregnancies were studied weekly in a prospective and longitudinal study. Uterine height, biparietal diameter (BPD), cranial perimeter (CrP) and abdominal perimeter (AbP) were measured. Amniotic fluid volume (AFV) was assessed. Of the sample selected, 58 neonates were appropriate for gestational age and 36 were small-for-date (17 symmetrical and 19 asymmetrical). The sensitivity values in diagnosis of small-for-dates were: 67% for BPD, 42% for CrP, 94% for AbP, 56% for Uterine Height and 28% for AFV. The specificity for the five variables ranged from about 91% to 100%. If we consider symmetrical and asymmetrical retardation separately, the sensitivity values for the former were: 94%, 77%, 100%, 77% and 24% for BPD, CrP, AbP, Uterine Height and AFV respectively. For symmetrical retardation, the sensitivity values were: 43%, 11%, 90%, 37% and 32% for BPD, CrP, AbP, Uterine Height and AFV respectively. The fetal cranial measurements were the only ones to demonstrate a different pattern of evolution in symmetrical and asymmetrical small-for-dates. This is therefore a useful measurement in making a differential diagnosis between both retardations. The earliest diagnoses were made in the symmetrical small-for-date group.
在一项前瞻性纵向研究中，每周对94例高危妊娠进行研究。测量子宫高度、双顶径（BPD）、头围（CrP）和腹围（AbP）。评估羊水体积（AFV）。在所选样本中，58例新生儿为适于胎龄儿，36例为小于胎龄儿（17例匀称型和19例非匀称型）。小于胎龄儿诊断中的敏感度值分别为：BPD为67%，CrP为42%，AbP为94%，子宫高度为56%，AFV为28%。这五个变量的特异度范围约为91%至100%。如果分别考虑匀称型和非匀称型发育迟缓，前者的敏感度值分别为：BPD为94%，CrP为77%，AbP为100%，子宫高度为77%，AFV为24%。对于匀称型发育迟缓，敏感度值分别为：BPD为43%，CrP为11%，AbP为90%，子宫高度为37%，AFV为32%。胎儿头颅测量是唯一能显示匀称型和非匀称型小于胎龄儿不同演变模式的指标。因此，这是在两种发育迟缓之间进行鉴别诊断的一项有用测量指标。最早的诊断是在匀称型小于胎龄儿组中做出的。
