What is the difference between height and recumbent length

If replicate measurements are indicated because of relatively low reliability, a second measurement should be taken, including repositioning the participant. A third measurement should be taken if the first two measurements differ by more than 1.

If it is necessary to take a third measurement, the two closest measurements are averaged. Should the third measurement fall equally between the first two measurements, all three should be averaged. An infantometer device is used. The device has a fixed headpiece, horizontal backboard, and movable foot piece. Position the child on the infantometer with the feet positioned against the foot piece Exhibit 1 and the head against the headpiece Exhibit 2.

Children often cry when placed on the infantometer, so ask the parent or guardian to stand between the examiner and recorder, make eye contact, and reassure the child. To do this, apply gentle traction to bring the top of the head in contact with the fixed headpiece. With the other hand, slide the foot piece to rest firmly against the soles of the feet. The toes should point upward with both soles of the feet flexed perpendicular against the acrylic foot piece.

To encourage the child to flex the feet, run the tip of your finger down the inside of the foot. NOTE: If you are unable to position both legs correctly, make certain that at least one leg is straight with the foot flexed against the foot piece so that a measurement can be made. The one-leg positioning is the exception rather than the rule and is only used when children are extremely agitated or uncooperative. Download PDF. Technicians should be trained in the basic techniques of anthropometric measurements and specifically in handling newborns.

This measure includes four protocols, and each protocol relates to the age of the participant and his or her ability to stand up straight. A fourth protocol for self-reported height is included but is considered a protocol of last resort when direct measurement of height or its proxy is not possible.

The standing height protocol is used for participants 2 years of age or older who can stand unassisted. The recumbent length protocol is used for all infants and children from birth through 47 months of age.

The knee height protocol was used for participants 60 years of age or older or for individuals who cannot stand unassisted. Study subject aged 16 years or older or by a knowledgeable adult proxy for children younger than 16 years of age. Any comments, suggestions or corrections? Please let us know. Search This Site.

Breastfed reference population to a primarily formula-fed reference population.

Weight-for-length chart to BMI-for-age chart. One set of cutoff values to another. Changes from a recumbent length measurement to a standing height measurement. Changes to a different cutoff value and a different reference population. When changing from the WHO-weight-for-age chart to the CDC weight-for-age chart at 2 years of age, the weight-for-age percentiles may change downward to a lower percentile.

During this transition, caution should be used in interpreting any changes. Growth measurements need to be used in conjunction with medical and family history if aberrant growth is identified. Growth monitoring is based on a series of measurements.
