JOURNAL OF INTELLECTUAL & DEVELOPMENTAL DISABILITY
Pica is a common problem in people with intellectual disability. Its signif
icance can be under-recognised by carers and healthcare professionals. Pica
can be a manifestation of a range of medical conditions and can lead to a
variety of complications including lead and nicotine toxicity, surgical int
ervention requirements, and parasitic infestation. The literature is review
ed for references to the epidemiology, aetiology and complications of pica
in people with intellectual disability. Studies of the prevalence of pica i
n institutional and community settings show lower rates in the community (0
.3-14.4%), although rates remain quite high in institutionalised population
s (9-25%). The psychological, cultural and medical theories on aetiology ar
e explored, along with complications. Areas for further research are highli
ghted.
