Behavioral interventions have been shown to be effective at reducing pica by individuals with intellectual disabilities. However, even in these cases, once the mineral problem is fixed, pica often continues and requires additional treatment. In rare cases, people who engage in pica may not be getting enough of certain minerals in their diet, such as iron. Paint chips and dirt can contain lead, so eating these items can result in lead poisoning. Depending on what the individual eats, pica can be quite dangerous and lead to infection, blockage, breaks or holes in the stomach or intestine, and choking. Individuals with ID have been reported to engage in pica with many different types of items including cigarette butts, paper, paint chips, rocks, sticks, and dirt, just to name a few. Anywhere from 6 to 26% of individuals with intellectual disabilities (ID) may engage in pica, and the behavior is more likely if the individual is diagnosed with autism or has more significant intellectual disabilities. In other words, pica involves eating items that are not food for at least one month, and the individual must be “too old” to be putting things into their mouth (i.e., individuals over the age of 2 years). Pica is generally defined as the consumption of nonnutritive items, which is inappropriate for developmental age, continues for more than a month, and is not part of a culturally sanctioned practice.
