BACKGROUND
Hip fracture is a preventable cause of disability among elderly people


OBJECTIVE
To study factors associated to hip fractures in Chile.

Compared with controls, cases had a higher body mass index, loss of height during life, rate of hysterectomy, incidence of smoking and a lower consumption of diary products.
