摘要

1985年计算的东德52,000多名新生儿妊娠第25至42周胎儿生长的百分位数曲线与1973- 1974年确定的相同人群的比率进行了比较,结果显示平均出生体重明显降低。除了方法上的差异(在新的研究中,主要是通过超声波测胎术对胎龄进行更精确的估计),这些差异似乎主要是这段时间内人口生殖行为变化的结果(胎次减少)。在不考虑种族特点的情况下比较不同人口时,必须考虑到一些对出生体重有重大影响的修正因素,即:胎次、间隔、母亲的年龄和身高。在评估新生儿成熟度时也必须记住这些变量,以便使出生体重与死亡率和发病率之间的关系标准化。作为计算百分位数曲线的基础,应优先考虑累积频率分布,而不是假设正态分布,因为胎儿疾病或发育异常会导致分布不均匀,并且过多地代表小日期胎儿。必须拒绝选择数据来计算正常值,因为这样做会带来任意的决定。

[Variability of percentile values of body measurements of newborn infants (with special reference to body weight)].

The percentile curves for fetal growth between the 25th and 42nd week of gestation calculated for more than 52,000 newborns in East Germany in 1985 were compared with the rates defined for the same population in 1973-74 and showed a significantly lower mean birth weight. Besides methodological differences (primarily a more precise estimation of gestational age in the new study by using ultrasound fetometry), the differences seem to be mainly the result of changes in the reproductive behaviour of the population over that period (decrease in parity). When comparing different populations independently of ethnic specificities, a number of modifying factors have to be taken into account which significantly influence the birth weight, namely: parity, spacing, age and stature of the mother. These variables have also to be remembered when assessing the maturity of newborns in order to standardize the birth weight in relation to mortality and morbidity. As a basis for calculating percentile curves the cumulative frequency distribution should be preferred, rather than assuming a normal distribution, since fetal diseases or developmental anomalies result in an uneven distribution with an over-representation of small for date fetuses. The selection of data for calculating normal values must be rejected because of the arbitrary decisions which this entails.
