buikomvang

Buikomvang, or abdominal circumference, is an anthropometric measure that quantifies the size of the abdomen. It is used in clinical and research settings to assess central adiposity, which is the distribution of body fat around the abdomen, and its association with metabolic and cardiovascular risk.

To measure buikomvang, a flexible tape is placed around the abdomen at a defined level, typically at the level of the navel (umbilicus) while the person stands relaxed. The measurement is taken after a normal exhalation, with the tape snug but not compressing skin, and the tape held horizontal. Some protocols use the midpoint between the lowest rib margin and the iliac crest. Clothing should be light and removed or adjusted. For reliability, multiple measurements are recommended and averaged.

Abdominal circumference values are used to screen for and monitor central obesity. Thresholds indicating elevated risk vary by guidelines and population; in many European guidelines, values around 94 cm (men) and 80 cm (women) indicate increased risk, with higher thresholds (about 102 cm for men and 88 cm for women) indicating a high risk category. Clinicians interpret buikomvang in the context of other measures such as BMI and waist-to-hip ratio, as well as age, sex, and ethnicity.

Measurement accuracy can be affected by breathing, posture, and clothing. It should not be used alone to diagnose health conditions, but as part of a broader assessment of metabolic risk.
