ABSTRACT

PURPOSE: This systematic review aimed to update fragility hip fracture incidences in the Asia Pacific, and compare rates between countries/regions.

METHOD: A systematic search was conducted in four electronic databases. Studies reporting data between 2010 and 2023 on the geographical incidences of hip fractures in individuals aged ≥50 were included. Exclusion criteria were studies reporting solely on high-trauma, atypical, or periprosthetic fractures. We calculated the crude incidence, age- and sex-standardised incidence, and the female-to-male ratio. The systematic review was registered with PROSPERO (CRD42020162518).

RESULTS: Thirty-eight studies were included across nine countries/regions (out of 41 countries/regions). The crude hip fracture incidence ranged from 89 to 341 per 100,000 people aged ≥50, with the highest observed in Australia, Taiwan, and Japan. Age- and sex-standardised rates ranged between 90 and 318 per 100,000 population and were highest in Korea and Japan. Temporal decreases in standardised rates were observed in Korea, China, and Japan. The female-to-male ratio was highest in Japan and lowest in China.

CONCLUSION: Fragility hip fracture incidence varied substantially within the Asia-Pacific region. This observation may reflect actual incidence differences or stem from varying research methods and healthcare recording systems. Future research should use consistent measurement approaches to enhance international comparisons and service planning.
