For men with spinal cord injuries, using a waist size of 86.5 cm instead of 102 cm identifies more people as obese (36% vs 3%), which is a big difference.

Using a waist size of 86.5 cm instead of 102 cm in men with spinal cord injuries better identifies who has obesity based on body fat percentage, catching more true cases (68.8% vs 6.3%) while still correctly identifying most non-obese people (90% vs 100%).

In men with spinal cord injuries, waist size strongly correlates with total body fat and belly fat, indicating it's a good measure of overall fatness.

For men with spinal cord injuries, a waist size of 86.5 cm better detects belly fat (visceral adipose tissue) than the standard cutoff, identifying more true cases (84.6% vs 7.7%) while still correctly identifying most people without excess belly fat (91.3% vs 100%).

For men with spinal cord injuries, a waist size of 86.5 cm corresponds to a lower heart disease risk threshold (6 instead of 10), identifying more people at risk.

BMI, waist size, and waist-to-height ratio all relate to how much fat is stored around the belly in people with spinal cord injuries.
