Osteoarthritis (OA) is a complex disease with increasing incidence. Key risk factors include age, obesity, and joint injury, highlighting opportunities for prevention and management.
Area of Science:
- Epidemiology
- Rheumatology
- Orthopedics
Background:
- Osteoarthritis (OA) poses a significant global health burden.
- Recent epidemiological studies reveal an increasing incidence of OA worldwide.
Purpose of the Study:
- To review recent research on osteoarthritis epidemiology.
- To identify prevalence, incidence, and risk factors for OA at personal and joint levels.
Main Methods:
- Systematic review of recent epidemiological studies on osteoarthritis.
- Analysis of person-level and joint-level risk factors.
Main Results:
- OA incidence is rising globally.
- Strong evidence links age, sex, socioeconomic status, family history, and obesity to OA incidence/progression.
- Joint injury and occupational loading are significant risk factors for incident OA.
- Moderate physical activity is not associated with increased OA risk.
- Emerging research explores links between OA and metabolic pathways, genetics, and biomechanics.
Conclusions:
- Osteoarthritis is a multifactorial disease with ongoing research into its mechanisms.
- Modifiable risk factors like obesity and joint injury offer targets for OA prevention.
- Mitigating these risks is crucial for reducing the impact of osteoarthritis.
