What percentage of the global population is estimated to be affected by rheumatoid arthritis?

The estimate that approximately 1% of the global population is affected by rheumatoid arthritis is based on various epidemiological studies that have consistently indicated this prevalence. Rheumatoid arthritis is an autoimmune disease that primarily affects joints but can also have systemic implications. The 1% figure provides a general contextual understanding of how common this condition is worldwide, reflecting its significance as a public health concern.

This statistic helps inform healthcare professionals, researchers, and policymakers about the impact of rheumatoid arthritis on the population, guiding resource allocation, research funding, and support services. Understanding prevalence rates is crucial for developing prevention strategies and patient management plans.

The other options, while representing percentages that could potentially be debated based on different populations or specific studies, do not align as closely with the widely accepted figure for the global prevalence of rheumatoid arthritis. This highlights the importance of relying on established data and consensus in the field of health statistics when discussing medical conditions.
