  1. Bone density and risk of hip fracture in men and women : cross sectional analysis.

    Article - En anglais

    Objective 

    To determine the relative contribution of decline in bone density to the increase in risk of hip fracture with age in men and women.

    Design 

    Incidence data of hip fracture from the general population were combined with the bone density distribution in a sample from the same population and with a risk estimate of low bone density known from literature.

    Setting 

    The Netherlands.

    Subjects 

    All people with a hospital admission for a hip fracture in 1993, and bone density measured in a sample of 5814 men and women aged 55 years and over in a district of Rotterdam.

    Main outcome measure 

    One year cumulative risk of hip fracture by age, sex, and bone density measured at the femoral neck.

    Results 

    A quarter of all hip fractures occurred in men.

    Men reached the same incidence as women at five years older.

    Controlled for age, the risk of hip fracture by bone density was similar in men and women.

    The risk of hip fracture increased 13-fold from age 60 to 80 ; decrease in bone density associated with age contributed 1.9 (95% confidence interval 1.5 to 2.4) in women and 1.6 (1.3 to 1.8) in men.

    Conclusions 

    The risk of hip fracture by age and bone density is similar in men and women.

    The decrease in bone density associated with age makes a limited contribution to the exponential increase of the risk of hip fracture with age.
