Association (odds ratio [OR], 95% confidence interval [CI]) between grip strength and walking speed combinations and falls, mortality, mobility limitation, and hip fractures in women. Models are adjusted for age, self-rated health, pain, use of statins, cognitive function, cancer, congestive heart failure, stroke, chronic obstructive pulmonary disease, and diabetes. Hip fracture model additionally adjusted for bone mineral density. Falls model includes 4,551 women ([913] 20.1% falls); Mortality model includes 4,736 women (1,258 [26.6%] deaths); mobility limitation model includes 1,500 women (344 [22.9%] mobility limitation); and the hip fracture model includes 1,745 women (166 [9.5%] hip fractures). Interaction between slowness and muscle weakness was significant for falls (P = .039), borderline significant for hip fracture (P = .076), and not significant for mobility limitation and mortality (P > .10).
