Hip fractures in the elderly: a world-wide projection

Area of Science:

• Gerontology
• Public Health
• Epidemiology

Background:

• Hip fractures are a significant public health issue in Western nations.
• Osteoporosis is often perceived as less prevalent in Asian, South American, and African countries.
• Demographic shifts will dramatically increase elderly populations globally in coming decades.

Purpose of the Study:

• To estimate the future global burden of hip fractures.
• To project hip fracture incidence across major continental regions by 2050.
• To highlight the evolving geographic distribution of hip fractures.

Main Methods:

• Utilized existing hip fracture incidence rates from global data.
• Applied these rates to projected population figures for 1990, 2025, and 2050.
• Calculated estimated hip fracture numbers for each major continental region.

Main Results:

• Global hip fractures are projected to increase from 1.66 million (1990) to 6.26 million annually by 2050.
• The proportion of hip fractures in Europe and North America will decrease from ~50% to ~25%.
• Steep increases in hip fractures are anticipated in Asia and Latin America.

Conclusions:

• Osteoporosis is poised to become a global health crisis within 50 years.
• Preventive measures for hip fractures are crucial for regions currently not prioritizing them.
• The study underscores the need for global public health initiatives addressing osteoporosis and hip fractures.
