摘　　要：利用１９８５～１９８９年我国７省９个县的２６１７１名及１９９０年２７省１０１个县的６８８７６名１～５岁儿童体重和上臂围数据，对国际上采用的诊断１～５岁儿童营养不良的上臂围界限值（＜１２．５ｃｍ为重度营养不良，１２．５～１３．５ｃｍ为中度营养不良）进行分析。结果表明１～５岁儿童用同一上臂围界限值灵敏度随年龄增长而下降，而特异度则随年龄的上升而上升，提示随年龄的增长漏检率越来越高。经判别分析提出各年龄组的上臂围界限值，但其漏检率和误判率也在３０％左右，本研究结果说明上臂围不是评价学龄前儿童营养不良的理想指标。The body weight, height and mid-upper arm circumference of 26171 subjects aged 1～5 in 9 counties of 7 provinces from 1985 to 1989 and 68876 children of the same ages in 101 counties of 27 provinces in 1990 were measured. The prevalence of malnutrition assessed according to the mid-upper arm circumfer ence value (<12. 5cm, as severely malnourished, 12.5￣13. 5cm as moderately malnourished) was evaluated with WHO standard (WT/A-2s and <-3s).The result showed that while age increasing, the sensitivity of mid-upper arm circumference decreased, but the specificity increased. The rates of false negative and false positive in different age groups were around 30%. It is suggested that mid-upper arm cirumference as an indicator is not good enough to be for assessing malnutrition in preschool children.
