21 (HealthDay News) Alcoholism and certain types of eating disorders share common genetic risk factors, according to a new study. Common genetic factors may be behind both alcoholism and specific symptoms of eating disorders — particularly the binge eating and purging habits of bulimia nervosa, according to new research. Alcohol use disorder (AUD) often seems to run in families, and we may hear about scientific studies of an “alcoholism gene.”. Genetics certainly influence our likelihood of developing AUD, but the story isn’t so simple. Research shows that genes are responsible for about half of the risk for AUD.
Therefore, genes alone do not determine whether someone will develop AUD. Statistically, a family history of alcoholism is linked to an increased risk of genetic predisposition to alcoholism, depending on how close the relatives are to each other. Children who have one parent who struggles with alcohol use disorder have a 3-4 times increased risk of becoming an alcoholic themselves. Genetic risk factors for eating disorders: an update and insights into pathophysiology Show all authors for example etanercept, have been used in other psychiatric disorders and may, Mazurek, U. Preliminary study of the expression of genes connected with the orexigenic and anorexigenic system using microarray technique in anorexia. Genetic connections between substance abuse and eating disorders have also been confirmed in numerous research studies, suggesting that there are at least some inherent factors that may be common to these behaviors.
Strong inherent factors may also contribute to the strong comorbidity eating disorders share with many other mental health. “During puberty, there is an increased risk for developing an eating disorder,” said Klump. “Up to 50 percent of this risk can be attributed to genetic factors that emerge during puberty.” Klump’s research looked at more than 500 female 14-year-old twins who were examined using sophisticated statistical modeling techniques. Eating disorders (EDs) occur in approximately 0.5–3.0% of the population, with more affected females than males (American Psychiatric Association [APA], 2000).The female-to-male ratio of ED diagnoses in nonclinical populations has been estimated at 10:1 ().However, recent research indicates a ratio of 4:1 for anorexia nervosa (AN; Woodside et al., 2001).
