Adults at least 65 years of age who participated in the Cardiovascular Health Study (CHS) comprised the cohort for the present study. The current investigation specifically explored if population-based screening for osteoporosis, or low bone density, was related to lower numbers of hip fractures as compared to standard medical care. Dual-energy x-ray absorptiometry (DEXA), or bone density scans, were conducted with 1,422 study participants while 1,685 participants received standard care. Participants were followed over a six-year time period with data coming from questionnaires, physical examinations and review of medication bottles.
- The incidence rate for hip fractures per 1,000 persons was 4.8 for the group screened for osteoporosis compared to 8.2 for the standard care group.
- Once propensity scores and sex were controlled, the likelihood of hip fractures was 36 percent lower over the six years of the study for the screened group.
- A significant relationship existed for participants who were either over age 85 or white, such that fewer hip fractures were related to being screened for low bone density.
- Results of the study also indicate that screening was beneficial for both women and men.
