There is a cultural part of the pica behavior we occasionally learn about. During the 1970s and 1960s, we learned about pica behavior in children due to the probmes of lead based paint, a requirement of home-builders in the early 1900s produced by health professionals in order to reduce mold growth in domestic settings–most lead paint used in the early 1900s was a consequence of the Chicago environment and mold infestations in much older homes, part for the course during the sanitation movement.
This new pica problem that is erupting much more slowly in the U.S. pertains to Caribbean and African American cultures. Numerous speculations appear in the medical literature about why this behavior continues, and it is usually linked to diet and nutrition related desires (the need for more iron for example).
Whatever the reason, some culturally-rich regions can be identified by reviewing the spatial distribution of these very unique cultural behaviors, as is the case for this mapping. On my Scoopit! page, you can see two maps conveniently side by side–the videomap of general African American/Caribbean linked diagnoses, culturally bound syndromes, genetic ICDs, Africa-/Caribbean-linked ecological diseases and other codes, in relation to this Pica related behavior.
