In Prudhoe Hospital, a large mental-handicap hospital of 1000 residents, it was found that of the 94 deaths that occurred between 1982 and 1986, three were closely associated with the habit of pica. These deaths occurred in severely and profoundly handicapped males, whose average age was 32, compared with an average age of death of 58 for the combined groups of severely and profoundly mentally handicapped patients (22 cases), and an average age of death of 60 for all degrees of handicap (94 cases). It seems likely that the habit of pica constitutes a cause of considerable morbidity and mortality in certain institutionalised patients.
在普拉德霍医院（一家拥有1000名住院患者的大型智障医院），人们发现，在1982年至1986年间发生的94例死亡病例中，有3例与异食癖习惯密切相关。这些死亡病例发生在重度和极重度智障男性中，他们的平均年龄为32岁，而重度和极重度智障患者合并组（22例）的平均死亡年龄为58岁，所有程度智障患者（94例）的平均死亡年龄为60岁。异食癖习惯似乎很可能是某些机构化患者中相当一部分发病和死亡的原因。
