Waist circumference (WC) is the simple measure of length around a person’s abdomen. It can be particularly important in people with SCI for health and for function as many experience lack of core function and weight fluctuations.
Waist circumference is usually measured after a normal expiration at the narrowest part of the waist, often defined as the midpoint between the crest of the ilium and the last rib. It can be measured in the seated or the supine positions, but will have a larger value in the supine (Sumrell et al. 2018). There is evidence that self-reported and measured WC have sufficient correlation to be used in research (Battram et al., 2011; Rimm et al., 1990).

Interpretability
MCID: not established for SCI
SEM:
- Standard Error of Estimate:
7.61 cm for walkers
4.00 cm for non-walkers
MDC:
- Mean (SD) Scores:
Seated Waist Circumference (cm) 88.8±9.3
Supine Waist Circumference (cm) 85.9±11.8 - Threshold Values:
Not established in SCI. In the general population, WC > 102cm in men and WC > 88 cm in women are at high risk for developing medical conditions.
Reliability
Intra-rater reliability for Waist Circumference is High (ICC=0.999)
(Edwards et al. 2008)
Validity
- There is High correlation with the bioelectrical impedance analysis (r = 0.83), Body fat where
Abdominal fat (r = 0.82) for mass and (r=0.76) for percentage, and Total fat (r = 0.73) for mass and (r=0.70) for percentage, - There is Moderate correlation with Framingham Risk Score (cardiovascular disease) (r = 0.66), and Body Mass Index (BMI) (Male: r = 0.46, Female: r = 0.45)
(Alschuler et al. 2012, Cragg et al. 2015, Eriks-Hoogland et al. 2011)
Responsiveness
