Mortality risk associated with low-trauma osteoporotic fracture and subsequent fracture in men and women.
JAMA 2009; 301(5):513-21JAMA

Abstract

CONTEXT

There are few data on long-term mortality following osteoporotic fracture and fewer following subsequent fracture.

OBJECTIVES

To examine long-term mortality risk in women and men following all osteoporotic fractures and to assess the association of subsequent fracture with that risk.

DESIGN, SETTING, AND PARTICIPANTS

Prospective cohort from the Dubbo Osteoporosis Epidemiology Study of community-dwelling women and men aged 60 years and older from Dubbo, Australia, who sustained a fracture between April 1989 and May 2007.

MAIN OUTCOME MEASURES

Age- and sex-specific standardized mortality ratios (SMRs) compared with the overall Dubbo population for hip, vertebral, major, and minor fractures.

RESULTS

In women, there were 952 low-trauma fractures followed by 461 deaths, and in men, 343 fractures were followed by 197 deaths. Age-adjusted SMRs were increased following hip fractures (SMRs, 2.43 [95% confidence interval [CI], 2.02-2.93] and 3.51 [95% CI, 2.65-4.66]), vertebral fractures (SMRs, 1.82 [95% CI, 1.52-2.17] and 2.12 [95% CI, 1.66-2.72]), major fractures (SMRs, 1.65 [95% CI, 1.31-2.08] and 1.70 [95% CI, 1.23-2.36]), and minor fractures (SMRs, 1.42 [95% CI, 1.19-1.70] and 1.33 [95% CI, 0.99-1.80]) for both women and men, respectively. Mortality was increased for all ages for all fractures except minor fractures for which increased mortality was only apparent for those older than 75 years. Increased mortality risk persisted for 5 years for all fractures and up to 10 years for hip fractures. Increases in absolute mortality that were above expected, for 5 years after fracture, ranged from 1.3 to 13.2 per 100 person-years in women and from 2.7 to 22.3 per 100 person-years in men, depending on fracture type. Subsequent fracture was associated with an increased mortality hazard ratio of 1.91 (95% CI, 1.54-2.37) in women and 2.99 (95% CI, 2.11-4.24) in men. Mortality risk following a subsequent fracture then declined but beyond 5 years still remained higher than in the general population (SMR, 1.41 [95% CI, 1.01-1.97] and SMR, 1.78 [95% CI, 0.96-3.31] for women and men, respectively). Predictors of mortality after any fragility fracture for both men and women included age, quadriceps weakness, and subsequent fracture but not comorbidities. Low bone mineral density, having smoked, and sway were also predictors for women and less physical activity for men.

CONCLUSIONS

In a sample of older women and men, all low-trauma fractures were associated with increased mortality risk for 5 to 10 years. Subsequent fracture was associated with increased mortality risk for an additional 5 years.
