To assess the reliability of percentage ideal weight for height (%WFH) as a measure in children.
Forty two dietitians calculated %WFH of six children. Eleven of the 42 repeated the calculations.
Interexaminer estimates varied by 16.5 to 40 percentage points (mean 27.8). Intraexaminer variability was also large.
%WFH is an unreliable measure of nutritional status.
评估身高理想体重百分比(%WFH)作为儿童营养状况衡量指标的可靠性。
42名营养师计算了6名儿童的%WFH。其中11名营养师重复了计算过程。
不同检查者的估计值相差16.5至40个百分点(平均为27.8)。同一检查者内部的差异也很大。
%WFH作为营养状况的衡量指标并不可靠。
