The Tallstick is a new, simplified anthropometric field tool which allows immediate visual interpretation of height-for-age. This tool was field tested in community-based programmes in Managua, Nicaragua, and the rural community of Los Zarzales, screening 1004 children aged 0-60 months for nutritional stunting. Overall sensitivity and specificity analysis comparing HAZ scores and Tallstick results revealed that the Tallstick correctly identified 83-85 per cent of severely stunted children (HAZ < -2.5) and two-thirds of those with HAZ of -2 and below. It also had good positive predictive value for the mildly stunted. As a screening tool for low weight-for-age, the Tallstick performed better than arm circumference. The best of the community volunteers trained with the Tallstick could use it as well as their trainers. Progressive stunting was found in the 280 children in the sample who did not receive any form of milk. The advantages of the Tallstick for community-level screening and the importance of sustained linear growth are discussed.
“高尺”是一种新型、简化的人体测量现场工具，可即时直观解读年龄别身高情况。该工具在尼加拉瓜马那瓜的社区项目以及洛斯萨尔扎莱斯农村社区进行了现场测试，对1004名0至60个月大的儿童进行营养发育迟缓筛查。通过比较身高别年龄标准差（HAZ）得分和“高尺”结果进行的总体敏感性和特异性分析显示，“高尺”能正确识别83%至85%的严重发育迟缓儿童（HAZ＜-2.5）以及三分之二HAZ为-2及以下的儿童。对于轻度发育迟缓儿童，它也具有良好的阳性预测值。作为年龄别低体重的筛查工具，“高尺”的表现优于臂围。接受“高尺”培训的社区志愿者中最优秀的成员使用该工具的水平与培训人员相当。在未接受任何形式牛奶的样本中的280名儿童中发现了进行性发育迟缓。文中讨论了“高尺”在社区层面筛查中的优势以及持续线性生长的重要性。
