Abstract
Peptic ulcer was studied at a California, USA institution for the mentally retarded. Of the 1700 residents at risk, 91 had X-ray or endoscopy evidence of peptic ulcers, a prevalence rate of 5.4%. Ulcer prevalence in the duodenum was more than twice that in the stomach and esophagus. All esophageal, gastric, and duodenal erosions or ulcer craters, acute or chronic, were considered. The more severely retarded patients showed a higher ulcer prevalence than those less retarded, and males demonstrated higher rates than females. The presence of medical and neurological disabilities, including limitations of vision and communication, was positively associated with ulcer development.
