To assess the ability of parents to estimate their children's weight.
We assembled a convenience sample of children, newborn to 5 years, who presented to the ED of a tertiary care hospital. Each child's mother or father was asked to estimate the child's weight as accurately as possible. The triage nurse then weighed the child on an electronic scale. An age-based formula was also used to estimate the child's weight. The parental estimate and the formula-based weight were compared with the weight indicated on the scale.
One hundred seventeen children were enrolled. The mean age was 26.7 months (range, newborn to 60 months). We analyzed agreement by plotting the percent difference between the weight estimates against the actual weights. The mean +/- SD difference between the parental estimate and the actual weight was 6.8% +/- 9.8%. Parental estimates were accurate to within 10% of the measured weight in 80% of the cases (94 of 117). The mean +/-SD difference between the formula-derived weight and the actual weight was 13.6% +/- 17.5%. The formula was accurate to within 10% of the measured weight in 46% of cases (54 of 117).
In 80% of cases, the parental estimate of the child's weight was within 10% of the measured weight. The parental estimate was more accurate than the formula-derived weight.
评估父母估计其子女体重的能力。
我们收集了一个便利样本，包括新生儿至5岁的儿童，他们前往一家三级护理医院的急诊科就诊。要求每个孩子的母亲或父亲尽可能准确地估计孩子的体重。然后分诊护士用电子秤给孩子称重。还使用了一个基于年龄的公式来估计孩子的体重。将父母的估计值和基于公式的体重与秤上显示的体重进行比较。
共纳入117名儿童。平均年龄为26.7个月（范围为新生儿至60个月）。我们通过绘制体重估计值与实际体重之间的百分比差异来分析一致性。父母估计值与实际体重之间的平均±标准差差异为6.8%±9.8%。在80%的病例（117例中的94例）中，父母的估计值与测量体重的误差在10%以内。公式得出的体重与实际体重之间的平均±标准差差异为13.6%±17.5%。在46%的病例（117例中的54例）中，该公式与测量体重的误差在10%以内。
在80%的病例中，父母对孩子体重的估计与测量体重的误差在10%以内。父母的估计比公式得出的体重更准确。
