Short-term mortality up for women aged 65 to 79, and for those older than 80 in very good health
THURSDAY, Sept. 29 (HealthDay News) -- There is an increased risk of mortality within the year after hip fracture in women aged 65 to 79 years, and in those older than 80 years who are in exceptionally good health, according to a study published online Sept. 26 in the Archives of Internal Medicine.
Erin S. LeBlanc, M.D., M.P.H., from the Kaiser Permanente Northwest in Portland, Ore., and colleagues investigated whether hip fracture was associated with short-term (<1 year), intermediate-term (>1 to ≤5 years), or long-term (>5 to ≤10 years) mortality. A total of 5,580 women, including 1,116 cases of hip fracture and 4,464 age-matched controls, were followed up for 20 years. The effect of health status was assessed in a subset of 960 healthy participants aged 80 years or older with good or excellent health at a 10-year follow up. Incident hip fractures were identified from radiology reports, and death was established by death certificates.
The investigators found that mortality increased more than two-fold in cases compared to controls in the year after fracture (adjusted odds ratio [OR], 2.4). Short-term mortality increased in cases aged 65 to 69 years, 70 to 79 years (OR, 5.0 and 2.4, respectively), and in the subset of women aged 80 years or older with good or excellent health (adjusted OR, 2.8). Survival was similar in hip fracture cases and controls after the first year, except in the 65-to-69-years age group, which continued to show increased mortality.
"Short-term mortality is increased after hip fracture in women aged 65 to 79 years and in exceptionally healthy women 80 years or older," the authors write.
