Association between low-frequency ultrasound and hip fractures - comparison with DXA-based BMD

Table 6 Logistic regression models without and with V _LF for having a hip fracture in a population-based sample of older women

	OR	(95% CI)	p-value
Lifestyle-related risk factors¹			0.002^*
TUG ≥ 11 s vs. less (referent)	3.4	(1.2 - 9.9)	0.026
Low PA vs. moderate to high (referent)	2.8	(1.0 - 7.5)	0.046
Coffee consumption > 3 cups/day vs. less (referent)	0.3	(0.1 - 1.0)	0.051
Lifestyle-related risk factors and V_LF ²			0.001^*
Low V_LF (0-25%) vs. Moderate or high (25-100%) (referent)	3.3	(1.2 - 9.0)	0.018
Low PA vs. moderate to high (referent)	3.1	(1.1 - 8.5)	0.028
TUG ≥ 11 s vs. less (referent)	3.1	(1.0 - 8.9)	0.042

Odds ratios (OR) are calculated compared to the NF group. TUG “Timed Up & Go” test, PA physical activity, CI confidence interval. The number of subjects in the analyses was Hip Fx n = 18, NF n = 296. ¹Age, BMI, TUG, PA, hypertension, coffee consumption, and smoking were included in the analysis to form the best model, ²The best model after including V_LF in the analysis, ^*p-value for the full model.
