56086-2

LOINC code 56086-2 identifies "Adult Waist Circumference Protocol". The state of the science does not indicate a clear choice of protocol at this time. Therefore, the PhenX Anthropometrics Working Group recommends that all three protocols (three different body sites, protocols A, B, and C below) be utilized in measuring waist circumference in adults. Furthermore, the protocols used should be recorded. Note: Waist circumference is measured on pregnant females. However, national reference data do not include pregnant females. For study participants, aged 16 years and older (protocols A-C): A. National Health and Nutrition Examination Survey (NHANES): Measurement of the participant's abdominal (waist) circumference is made at the uppermost lateral border of the ilium using a tape measure. B. Women's Health Initiative / For Good Measure Study: Measurement of the participant's waist circumference is made at the natural waist. C. Framingham Heart Study: Measurement of the participant's waist circumference is performed at the umbilicus (e.g., navel or belly button).

This code measures Adult Waist Circumference Protocol in ^Patient. It belongs to the PANEL.PHENX class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
