The molecular mechanisms at the origin of eating disorders (EDs), including anorexia nervosa (AN), bulimia and binge-eating disorder (BED), are currently unknown. Previous data indicated that immunoglobulins (Igs) or autoantibodies (auto-Abs) reactive with α-melanocyte-stimulating hormone (α-MSH) are involved in regulation of feeding and emotion; however,(More)
Neuropeptide S is involved in anxiety and arousal modulation, and the functional polymorphism Asn107Ile (rs324981, A > T) of the neuropeptide S receptor gene (NPSR1) is associated with panic disorder and anxiety/fear-related traits. NPSR1 also interacts with the environment in shaping personality and impulsivity. We therefore examined whether the NPSR1 A/T(More)
Adverse life events have been shown to predict weight fluctuations and dietary restraint, as well as eating disorders during adolescence or early adulthood. Since the s-allele carriers of the 5-HTT gene-linked polymorphic region (5-HTTLPR) are biologically more reactive to stress related stimuli, we aimed to explore whether the eating disturbances are(More)
Brain-derived neurotrophic factor (BDNF) regulates food intake and energy metabolism. It has also been suggested that mutations in the human BDNF gene and its receptor TrkB account for disturbed eating and obesity. The Met-allele of the BDNF Val66Met polymorphism has been associated with eating disorders, but the underlying mechanism of its contribution is(More)
OBJECTIVE Monoamine oxidase A (MAOA) gene promoter region includes a variable number of tandem repeat (VNTR) associated with antisocial behaviour in adverse environment. We have examined the effect of the MAOA-uVNTR on mental health and academic success by using a population representative sample and a longitudinal design. METHODS The data of the older(More)
The COMT Val158Met polymorphism has been associated with anxiety and affective disorders, but its effect on anxiety-related personality traits varies between studies. Our purpose was to investigate the effect of COMT Val158Met on personality traits from adolescence to young adulthood in a population representative Caucasian birth cohort. Also its(More)
This study aimed to examine the structure of fears of youth, and its associations with gender, genetic variation of the serotonin transporter (5-HTTLPR), and perceived maternal acceptance/rejection and control, in a population-representative sample. Participants were 453 adolescents and 540 young adults. Fears were assessed by a 18-item Fear Questionnaire,(More)

OBJECTIVE The s-allele of the 5-HTTLPR has been suggested to lead to the development of less efficient and less flexible 5-HT system and has been associated to different forms of psychopathology. It has also been shown that alterations in serotonergic activity contribute to the pathophysiology of binge eating but it is not clear which changes in 5-HT(More)
This study investigated the associations between emotional fluctuations and emotion regulation difficulties in predicting binge eating and overeating episodes using the experience sampling method among 97 women and 61 men. Among women, fluctuations in negative emotion, emotion regulation difficulties, restrained eating, and the interaction of negative(More)
