Table 3.

Odds ratios and 95% confidence intervals for the association between foot posture, dynamic foot function and falls, adjusting for age, BMI and cohort.

	Any Fall	1 Fall	2+ Falls
Foot posture
Normal (referent)	1.0	1.0	1.0
Cavus	0.93 (0.67, 1.28)	0.92 (0.63, 1.35)	0.95 (0.57, 1.58)
Planus	1.23 (0.89, 1.71)	0.99 (0.67, 1.46)	1.78 (1.10, 2.87)
Dynamic foot function
Normal (referent)	1.0	1.0	1.0
Pronated	1.09 (0.78, 1.51)	1.28 (0.88, 1.87)	0.75 (0.44, 1.30)
Supinated	1.10 (0.81, 1.50)	1.01 (0.69, 1.47)	1.24 (0.79, 1.93)

Foot posture was derived from the Modified Arch Index, measured during quiet standing. Dynamic foot function was estimated from the Center of Pressure Excursion Index measured while walking at a self-selected pace.
