Several factors have been associated with an increased risk of bed-wetting, including:

  • Sex. Bed-wetting can affect anyone, but it's twice as common in boys than girls.
  • Family history. If both of a child's parents wet the bed as children, their child has an 80 percent chance of wetting the bed, too.
  • Attention-deficit/hyperactivity disorder (ADHD). Bed-wetting is more common in children who have ADHD.
