The annual hospitalization expense of hip fractures cost the Central Health Insurance Department around 1.3 billion Taiwanese dollars. This accounted for one-fifth of all fractures, and the proportion of the hip fracture is increasing by 2.8 % annually. The mortality rate associated with hip fracture is 8.4 ~ 36% in their first year. Therefore, the subject of hip fracture in the elderly cannot be underestimated. This study was a case control study. Data were collected via retrospective chart review and questionnaires. Research subjects comprised of elderlies above the age of 65 and were taken from an orthopedic ward and a health examination outpatient clinic in a medical center in midland of Taiwan. By reviewing medical records in the orthopedic ward, patients with low energy trauma resulting in hip fractures were placed in Group A (trauma group). By reviewing medical records in the health examination clinic, patients with previous non-hip related low energy trauma were placed in Group B (control group). We collected information related to hip fracture risk factors, including demographic data, lifestyle, and medical history. The results showed that the average age of the hip fracture group is higher than the non-hip fracture group; body mass index of the hip fracture group is lower than the non-hip fracture group, with significant differences (p < .05). Factors including patient gender, history of alcoholism, exercise habits, history of stroke, diabetes mellitus, hypertension, depression and past fractures are the risk factors of hip fracture (all with significant differences).
