Spaceflights over 90 days linked to higher hip fracture rates in astronauts

New research in Mayo Clinic Proceedings found higher rates of hip fractures among astronauts after spaceflights lasting more than 90 days compared with shorter flights or non-astronauts. The authors call for expanded assessment of astronauts' long-term skeletal health.

• Flights longer than 90 days linked to higher hip fracture rates
• Risk exceeds that after shorter flights and in non-astronauts
• Findings published in Mayo Clinic Proceedings
• Researchers urge broader monitoring of astronauts' bone health
