ABSI Calculator
Calculate your A Body Shape Index and assess health risks
A Body Shape Index (ABSI) is a metric developed to better predict the health implications of body shape. It considers:
- Waist Circumference
- Height
- Weight (through BMI)
ABSI was developed to address limitations of BMI by considering body shape and fat distribution, particularly abdominal fat, which is a known health risk factor.
For accurate ABSI calculation, measure:
- Height: Stand straight against a wall, without shoes
- Weight: Use a calibrated scale, preferably in the morning
- Waist Circumference: Measure at navel level, while standing and after normal exhalation
Take measurements in the morning, before eating, for most consistent results.
ABSI results are interpreted using z-scores:
- Very Low Risk: z-score < -0.868
- Low Risk: -0.868 to -0.272
- Average Risk: -0.272 to 0.229
- High Risk: 0.229 to 0.798
- Very High Risk: > 0.798
Z-scores compare your ABSI to population averages, accounting for age and gender.
How is ABSI different from BMI?
While BMI only considers height and weight, ABSI also takes into account waist circumference, providing insight into body shape and fat distribution. This makes it particularly useful for assessing health risks related to central obesity.
How often should I measure my ABSI?
Monthly measurements can help track changes, but significant changes typically occur over longer periods. Consistency in measurement timing and technique is important for accurate tracking.
Can ABSI predict health outcomes?
Research shows ABSI correlates with mortality risk better than BMI alone, particularly for deaths related to cardiovascular disease. However, it should be used alongside other health indicators for a comprehensive assessment.
