Certain body circumferences, such as the mid-upper arm circumference, are regarded as useful indicators of the nutritional status of children. The insertion tape is designed to reduce errors of measurement, prone to occur with the present tapes. At the widened origin of the new tape is a narrow slot perpendicular to the tape's long axis. The measurer threads the distal end of the tape though this slot, tightens to the required tension around the circumference and reads from an open window near the slot. Modifications of the basic tape for specific uses of measurement, screening and survey, are described.
某些身体周长，如上臂中部周长，被视为儿童营养状况的有用指标。插入式卷尺旨在减少使用现有卷尺时容易出现的测量误差。新卷尺在加宽的起始端有一个与卷尺长轴垂直的窄槽。测量人员将卷尺的远端穿过这个槽，围绕周长拉紧到所需的张力，然后从槽附近的一个开口窗口读取数据。文中还描述了针对特定测量、筛查和调查用途对基本卷尺的改进。
