Answer

In general, the frequency of IBD is similar in males and females, with some studies showing a very slight female predominance. The rate of Crohn disease is 1.1-1.8 times higher in women than in men. [38] This pattern is reversed with pediatric IBD, which has a higher incidence in boys than in girls (pediatric male-to-female ratio, ~1.6:1). In Japan, a male predominance exists. [12]
