Ankylosing spondylitis is more common in which sex?

• A. Women
• B. Men
• C. Both
• D. Not specified

Answer: (B)

Ankylosing spondylitis tends to affect men more than women. In most populations, the disease shows a clear male predominance, with prevalence roughly two to three times higher in men than in women, and onset typically in the late teens to early 30s. Because of this strong epidemiologic pattern, the correct answer is that the condition is more common in men. While women can develop AS, they often have different or subtler presentations and may be diagnosed later, but the overall distribution remains skewed toward males.
