Impact of waist circumference on the risk of vertebral fracture: A nationwide cohort study in South Korea

Evidence on the association between abdominal obesity and vertebral fracture (VF) risk is limited. We examined the association of waist circumference (WC) and abdominal obesity with VF risk in 352,095 South Korean participants aged 75.0 cm (HR: 0.81, 95% CI: 0.75-0.88) and increased in those with WC 85.0-89.9 cm (HR: 1.12, 95% CI: 1.02-1.22), 90.0-94.9 cm (HR: 1.19, 95% CI: 1.08-1.32), and 95.0 cm (HR: 1.27, 95% CI: 1.12-1.43) compared with those with WC 80.0-84.9 cm. This association persisted after stratification by age in women. WC and abdominal obesity were positively associated with VF risk in women, and abdominal obesity was associated with VF risk even in men. The consideration of WC and controlling abdominal obesity may be helpful in reducing future VF risk.

Automated summary

The study found that waist circumference and abdominal obesity were positively associated with vertebral fracture risk in women, and abdominal obesity was also associated with vertebral fracture risk in men. Therefore, considering waist circumference and controlling abdominal obesity may help reduce the risk of future vertebral fractures.
