Answer

Overall, the male-to-female ratio is approximately 3:1. With advancing age, gender difference becomes marked; in patients older than 4 years, the male-to-female ratio is 8:1.

Two thirds of children with intussusception are younger than 1 year; most commonly, intussusception occurs in infants aged 5-10 months. Intussusception is the most common cause of intestinal obstruction in patients aged 5 months to 3 years.

Intussusception can account for as many as 25% of abdominal surgical emergencies in children younger than 5 years, exceeding the incidence of appendicitis. Although extremely rare, intussusception has been reported in the neonatal period.
