Abstract

To investigate the recent longitudinal trend of hip fractures (including cervical and trochanteric fractures) in Taiwan's elderly population (≥ 65 years), a nationwide descriptive epidemiological study was conducted using the database of the Bureau of National Health Insurance from 1996 through 2002. Frequencies and incidences of hip fracture by gender, fracture site, and age group were estimated, and the 7-year incidence trend was further evaluated. The results showed that a total of 75,482 hip fractures occurred during the study period with an incidence rate of 57.54 per 10,000 per year. Overall incidence significantly increased by 30% (p <0.0001), from 49.56 to 64.37 per 10,000 per year during the 7-year study period. The increase in rates was greater in males (36%) than in females (22%). The average female-to-male ratio was 1.76, lower than those in many countries. In females, the annual incidence of cervical fracture was higher than that of trochanteric fractures throughout the 7 years, while the incidence of trochanteric fractures was higher than cervical fractures each year in males (p <0.0001). The average annual incidence of patients older than 85 years was 9.9 times higher than that of aged 65 to 69 years in females and 7.9 times in males. Development and implementation of public health strategies for hip fractures should more focus on these subgroups in Taiwan's rapidly aging society.
