Background Hip fracture causes significant morbidity and mortality in older
women.
Aim To document factors contributing to the risk of hip fracture in older w
omen and to assess the effect of hip fracture on subsequent mortality.
Methods Case-control study of 89 women with hip fracture and 89 controls, w
ith two-year follow-up. Singh index and bone mineral density were calculate
d.
Results Osteoporotic indices did not differ significantly between cases and
controls. Significant predictors of risk were sleeping tablets. perception
of health as fair/poor and a lower mental status score. Patients were 3.57
times more likely to die in the first year after fracture, with no differe
nce between the groups in year two. After adjustment. hip fracture did not
remain significantly associated with mortality, inability to walk 100 yards
alone prior to fracture and lower social class were significantly associat
ed with mortality at 12 months. Age alone was significantly associated at 1
2-24 months.
Conclusions Factors related to falls and fracture may be more discriminator
y predictors of hip fracture risk than osteoporosis in older females. Medic
ations for sleep should be prescribed with caution. Hip fracture may have a
n independent effect on one year mortality. this effect is not seen in the
second year.
