Hip fractures in older women increases short term risk of death, according to a report published in the Archives of Internal Medicine. The results of a complex meta-analysis revealed that women age 60 - 69 are 5.0 times more likely to die within one year of hip fracture; the risk to women age 70 - 79 is 2.4 times, and the risk to women age 80 and above is 2.8 times - all of which underscores the seriousness of broken bones in the elderly population.
The National Institutes of Health funded the Study of Osteoporotic Fractures (SOF), which examined osteoporosis and aging in women aged 65 and older. The SOF, which began in 1986, collected data on the subject of older women's health including breast cancer risk, stroke and total and cause-specific mortality.
In 1986 - 1988, researchers recruited 9704 elderly women age 65 and older from four US regional locations: Baltimore County, Maryland; Minneapolis, Minnesota; Portland, Oregon; and the Monongahela Valley in Pennsylvania for participation in the Study of Osteoporotic Fractures (SOF). From this number, 5580 ambulatory women were tracked for twenty years. Investigators performed an age match comparison of 1116 women who suffered hip fractures during the course of the study against the 4464 participants (control group) who did not incur such injuries.
Researchers observed that women who suffered hip fractures tended to have lower body mass index (BMI), lower bone mineral density (BMD), and smoked more than the healthy controls. From here the results become even more startling.
Nearly Half Of All Elderly Women Who Participated In The SOF Died
Investigators observed that 2690 women (48.1%) who participated in the SOF died within 14 years of follow up. Mortality risk was highest during the first year following hip fracture, with 189 cases reported. Moreover, 72.5% of those deaths occurred within the first six months of injury. This suggests an overall decline in the health of elderly women who suffered hip fractures.
Interestingly, younger women suffered greater short-term hip fracture mortality risk than women above age 80. In fact, scientists observed a decline in hip fracture deaths as women aged. Women age 60 to 69 experienced a five fold mortality risk within the first year of breaking a hip, whereas the mortality risk during the first year after hip fracture did not increase for women age 80 and older. Women age 70 -79 had a mortality risk in the first year after a hip break that was intermediate between the younger and older participant groups.
The majority of the women who died suffered from coronary heart disease, cancer and stroke; this encompassed the hip fracture participants and healthy controls. However, hip fracture was associated with higher mortality for the following conditions:
- pneumonia
- cognitive disorders
- osteoporotic fracture
Other Important Observations Made During The Study of Osteoporotic Fractures
Erin S. LeBlanc and her team made other observations worth noting. For example:
- The team separately examined women 80 years of age and older whom were reportedly of good or excellent health, and discovered a 2-fold increased risk of death within the first year of suffering a hip fracture.
- When looking at long term mortality by age and health status, women age 60 - 69 were increasingly at risk in terms of intermediate (5 year) and long term (10 year) mortality.
- The oldest SOF participants (women age 80 and older) had no intermediate or long term increased risk of mortality after hip fracture regardless of health.
- Women age 80 and older had no increased short - term mortality risk after suffering a broken hip.
What Does The Study Of Osteoporotic Fractures Mean To You?
Dr. LeBlanc mentioned that the observational study did have some limitations, most notably that the majority of SOF participants were post menopausal white women age 65 and older and "may not be generalizable to men, other ethnic groups and younger women." Nonetheless, the study underscores the need for people to take care of themselves and to look out for others.
Hip fractures among the elderly is a traumatic and, in many cases, potentially fatal event. If you know of anyone who could be at risk for such injury, look in on them from time to time. Be considerate of their age and physical condition and offer to help them if possible.
If you happen to be an older person who is prone to such injury, pay close attention to your health and seek help from family, friends, neighbors and health care professionals when necessary. You owe it to yourself.
