The relationship between anorexia nervosa (AN) and sociocultural facto
rs is examined. Anorexia nervosa was first described in the West and w
as reported as particularly rare or absent in Eastern cultures. Howeve
r, the frequency of its presentation has increased worldwide over the
past two decades, probably as a consequence of changes in cultural nor
ms and concepts of feminine beauty and an increasing inflow of Western
values into other countries. Sociocultural factors are important in t
he development of AN in psychologically vulnerable young females, alth
ough other factors may also be implicated.
