本分析的目的是确定是否可以从回顾性调查中获得有关出生体重的有用信息。1986年秘鲁人口健康调查收集了1981- 1986年期间出生的婴儿出生时的体重（以克为单位）和相对大小的主观评估。简单的表格表明，这两项措施的报告是相当高的质量。然而，更详细的分析表明，排除大部分（近三分之一）的数字权重缺失的答复可能会导致偏差的发生率和相关的低出生体重儿，婴儿死亡率水平，并可能低出生体重儿的相对死亡风险的估计。研究结果强调，在相当一部分婴儿出生于正规保健系统之外的人口中，除了关于数字重量的信息外，还必须收集关于婴儿相对大小的数据。主观评估允许分析员检查缺失数字体重的婴儿被选择的程度，并评估基于具有报告体重的出生子样本的估计值的偏倚程度。
The objective of this analysis is to determine whether useful information on birthweight can be obtained from a retrospective survey. The 1986 Peru Demographic Health Survey collected both numerical weights (in grams) and subjective assessments of relative size at birth, for infants born during 1981-86. Simple tabulations suggest that reports of both measures are of reasonably high quality. However, a more detailed analysis demonstrates that exclusion of the large proportion (almost one-third) of missing responses on numerical weights can lead to biases in the resulting estimates of the incidence and correlates of low birthweight, of the level of infant mortality, and probably of the relative risk of mortality for low birthweight infants. The results emphasize the necessity of collecting data on the relative size of infants, in addition to information on numerical weights, in populations in which a substantial fraction of infants are born outside the formal health system. The subjective assessments allow the analyst to examine the extent to which infants with missing numerical weights are select and to assess the degree of bias in estimates which are based on the subsample of births with reported weights.
