摘要
Alterations in serotonin function have been implicated in both anorexia and bulimia nervosa, and previous studies suggest associations between serotonin function and variations in pathological personality traits. Women meeting DSM-IV criteria for anorexia nervosa, (AN, 16 with the restricting subtype and 14 with the binge-purge subtype) and 49 healthy control women (CW) provided blood samples for analyses of platelet [H-3]paroxetine binding. Participants also filled out questionnaires tapping eating disorder symptoms, depression, and personality pathology. Compared with CW, women with restricting and binge-purge AN had significantly lower levels of paroxetine binding (respectively: 1012+487 vs. 560+253 vs. 618+217 fmol/mg protein). Simple correlation analyses showed that, within AN but not within controls, paroxetine binding was inversely related to dieting preoccupations, affective instability, anxiousness, compulsivity, restricted expression and social avoidance but independent of age, body mass index, depression, and other eating symptoms. Findings suggest that reduced peripheral serotonin transporter density in AN relates to increased dieting preoccupations, affective instability and anxiousness-fearfulness.
