Which age group is most commonly affected by polymyalgia rheumatica?

Polymyalgia rheumatica is a condition that primarily affects older adults, with the most common age group being over 50 years. The condition typically presents with symptoms such as muscle pain and stiffness, particularly in the shoulders and hips. The incidence of polymyalgia rheumatica increases significantly with age, and it is rare in individuals under 50 years.

The correct answer highlights the typical demographic most affected by this condition, emphasizing that older adults are disproportionately represented among those diagnosed. Studies indicate that polymyalgia rheumatica is less common in younger populations, making the age group over 50 years the most accurate choice when identifying the demographic most frequently affected by this disease. This age-related predisposition is also associated with the development of various other conditions, including giant cell arteritis, which can co-occur with polymyalgia rheumatica in older populations.
