Two studies of adults with intellectual disabilities living in institutions found that 21.8% [40] and 25.8% [41] of these groups had pica. [42] Prevalence rates for children are unknown. [42] [43] Young children commonly place non-nutritious material into their mouths. This activity occurs in 75% of 12-month-old infants, and 15% of two- to ...
