Previous investigations have suggested that ghrelin, an endogenous orexigenic peptide, is involved in the pathology of eating disorders. We conducted a study to determine whether any preproghrelin gene polymorphisms are associated with eating disorders. Three hundred thirty-six eating disorder patients, including 131 anorexia nervosa (AN)-restricting types(More)
The factor structure and internal consistency of the Japanese adaptation of the State-Trait Anxiety Inventory Form Y (STAI-JY) were examined for 218 Japanese clinical outpatients (86 males, 132 females) with psychiatric and/or psychosomatic complaints. An initial principal-component analysis revealed that the first three components were considered to(More)
The Met66 allele of the Val66Met polymorphism in the brain-derived neurotrophic factor (BDNF) gene has been reported to be associated with anorexia nervosa (AN), and also lower minimum body mass index (BMI) and higher harm avoidance in AN. We genotyped the Val66Met polymorphism (rs6265) in 689 AN cases and 573 control subjects. There were no significant(More)
Energy expenditure abnormalities have been observed in anorexia nervosa (AN). The uncoupling proteins (UCPs) have been implicated as having a role in energy metabolism and thermogenesis, and an association between a marker flanking the UCP-2/UCP-3 gene cluster and AN has been reported. Also known are insertion/deletion and -866G/A polymorphisms in the UCP-2(More)
BACKGROUND Patients with anorexia nervosa-restricting type (AN-R) sometimes develop accompanying bulimic symptoms or the full syndrome of bulimia nervosa (BN). If clinicians could predict who might change into the bulimic sub-type or BN, preventative steps could be taken. Therefore, we investigated anthropometric and psychological factors possibly(More)
BACKGROUND Patients with anorexia nervosa restricting type (AN-R) often develop bulimic symptoms and crossover to AN-binge eating/purging type (AN-BP), or to bulimia nervosa (BN). We have reported earlier that genetic variants of an orexigenic peptide ghrelin are associated with BN. Here, the relationship between a ghrelin gene variant and the rate of(More)
