Which group of people is most likely to experience cast syndrome?

Cast syndrome, also known as "superior mesenteric artery syndrome," occurs when a cast or restrictive device compresses the abdominal area, leading to intestinal obstruction or other gastrointestinal symptoms. This condition is particularly likely in anyone who is placed in a body cast, regardless of age or activity level.

Individuals in body casts may experience difficulty with mobility, which can exacerbate gastrointestinal issues. When the body cast restricts movement and pressure is applied to the abdominal area, it heightens the risk of developing this syndrome.

The other groups listed may not capture the wide-ranging risk present for individuals in body casts. While children and athletes might face particular risks within their activity contexts, it is the broader classification of "anyone in a body cast" that encompasses those at risk for developing cast syndrome, making it the most inclusive and accurate response.
