World-wide projections for hip fracture

Area of Science:

• Gerontology
• Epidemiology
• Public Health

Background:

• Hip fractures represent a significant global health burden, with incidence rates varying by region and demographics.
• Understanding current and future trends in hip fracture incidence is crucial for public health planning and resource allocation.

Purpose of the Study:

• To estimate the current and project the future worldwide incidence of hip fractures.
• To analyze demographic shifts and secular trends influencing hip fracture risk.
• To highlight the escalating socioeconomic impact, particularly in Asia.

Main Methods:

• A comprehensive survey of existing data on hip fracture incidence.
• Analysis of global population trends and historical changes in hip fracture risk.
• Computation of projected hip fracture numbers for 2025 and 2050.

Main Results:

• In 1990, an estimated 1.26 million hip fractures occurred globally.
• Projections indicate hip fractures could double to 2.6 million by 2025 and reach 4.5 million by 2050, assuming stable incidence rates.
• The percentage increase is higher in men (310%) than women (240%).
• With secular trend considerations, global hip fractures may range from 7.3 to 21.3 million by 2050.
• Asia's share of global hip fractures is expected to rise from 26% in 1990 to 45% by 2050.

Conclusions:

• The global socioeconomic impact of hip fractures will dramatically increase, with a disproportionate rise in Asia.
• There is an urgent need for the development and implementation of effective hip fracture prevention strategies.
• Developing countries require particular attention for preventive interventions due to anticipated demographic shifts.
