To assess the effectiveness of the newly developed individualised birthweight ratio in identifying growth retarded infants.
Prospective observational study.
Obstetric unit, City Hospital Nottingham.
Two thousand eight hundred and thirty-five women delivered between December 1991 and July 1992 and the infants of 616 of these selected by virtue of their birthweight for gestation and individualised birthweight ratio centile positions.
Skinfold thickness and ponderal index measurements, occurrence of abnormal fetal heart rate patterns, operative delivery due to fetal distress and the need for neonatal resuscitation.
Using an individualised birthweight ratio less than the 10th centile as a cut-off results in 25% of those less than the 10th centile of birthweight for gestation being reclassified as normally grown. A slightly larger group are reclassified as small; significantly more of these infants have abnormal ponderal indices and skinfold thicknesses, suffer abnormal fetal heart rate patterns, operative delivery for fetal distress and need neonatal resuscitation than do those who are reclassified as normally grown.
The individualised birthweight ratio combines the simplicity of birthweight measurement with the accuracy of clinical measurements in the identification of the growth retarded baby.
评估新开发的个体化出生体重比在识别生长受限婴儿方面的有效性。
前瞻性观察研究。
诺丁汉市医院产科病房。
1991年12月至1992年7月间分娩的2835名妇女，以及其中616名婴儿，这些婴儿根据其出生体重与孕周的关系以及个体化出生体重比百分位数进行选择。
皮褶厚度和 ponderal 指数测量、异常胎儿心率模式的发生情况、因胎儿窘迫进行的手术分娩以及新生儿复苏的需求。
以低于第10百分位数的个体化出生体重比作为临界值，会使那些出生体重低于孕周第10百分位数的婴儿中有25%被重新分类为正常生长。有稍多一组被重新分类为小；与被重新分类为正常生长的婴儿相比，这些婴儿中有显著更多的婴儿 ponderal 指数和皮褶厚度异常，出现异常胎儿心率模式，因胎儿窘迫接受手术分娩且需要新生儿复苏。
个体化出生体重比在识别生长受限婴儿时，将出生体重测量的简单性与临床测量的准确性结合了起来。
