The accuracy of identifying children with growth failure and/or clinically severe protein-energy malnutrition (PEM) from a single measure of length or weight for age from birth to 36 months was determined. Growth data were treated cross-sectionally and compared with National Center for Health Statistics growth standards in order to determine the sensitivity, specificity and positive predictive value of a single cross-sectional measure of weight-for-age or length-for-age in identifying children diagnosed via longitudinal records. Under 6 months of age, neither weight nor length for age was an adequate predictor of growth failure or clinical malnutrition; from 12 to 36 months, screening measures based on anthropometry were much improved. It was concluded that a single measure of weight or length for age taken close to the first birthday could identify up to 78% of the future second and third year cases of clinically severe PEM. Implications and limitations are discussed.
研究确定了根据出生至36个月龄儿童的单一身长或体重测量值来识别生长发育迟缓儿童和/或临床重度蛋白质-能量营养不良（PEM）儿童的准确性。对生长数据进行横断面分析，并与美国国家卫生统计中心的生长标准进行比较，以确定单一横断面年龄别体重或年龄别身长测量值在识别通过纵向记录确诊的儿童时的敏感性、特异性和阳性预测值。6个月龄以下，年龄别体重和年龄别身长均不是生长发育迟缓或临床营养不良的充分预测指标；12至36个月龄时，基于人体测量学的筛查指标有了很大改善。研究得出结论，在接近1岁生日时进行的单一年龄别体重或身长测量能够识别出高达78%的未来第二和第三年出现临床重度PEM的病例。文中还讨论了研究的意义和局限性。
