异食癖

定义

异食癖的特点是经常食用非营养物质，如非食物的物体和材料（如粘土、土壤、粉笔、石膏、塑料、金属和纸张）或食物原料（如大量的盐或玉米粉），这种行为持续或严重到需要临床关注的程度，而这些人已经达到可以区分食用和非食用物质的发育年龄（大约2岁）。也就是说，该行为对健康造成损害，功能受损，或因摄入的物质或物品的频率、数量或性质而造成重大风险。

Pica is characterised by the regular consumption of non-nutritive substances, such as non-food objects and materials (e.g., clay, soil, chalk, plaster, plastic, metal and paper) or raw food ingredients (e.g., large quantities of salt or corn flour) that is persistent or severe enough to require clinical attention in an individual who has reached a developmental age at which they would be expected to distinguish between edible and non-edible substances (approximately 2 years). That is, the behaviour causes damage to health, impairment in functioning, or significant risk due to the frequency, amount or nature of the substances or objects ingested.
