Causes
Biologcal factors
Genetics six to ten percent of siblings of affected women suffer from anorexia nervosa.There is an increased concordance amongst monozygotic twins, suggesting a genetic predisposition.
Hormonal The reductions in six hormones and the hypothalamic-pituitary-adrenals axis are secondary to malnutrition and commonly reversed by refeeding.
Psychological factors Anorexic eating behavior is thought to originate from an psychoneurotic fear of gaining coefficient due to a unshapely self image and is maintained by various cognitive biases that alter how the strained individualist evaluates and thinks about their body, food and eating. This is not a perceptual problem, but one of how the perceptual information is evaluated by the strained person. People with anorexia nervosa seem to more accurately judge their own body ikon while absent a self-esteem boosting bias.People with anorexia nervosa also have other psychological difficulties and noetic illness. Clinical depression, psychoneurotic ambitious disorder, center abuse and one or more personality disorders haw be the most probable conditions to be comorbid with anorexia. High-levels of anxiety and depression are probable to be present disregarding of whether they fulfill diagnostic criteria for a specific syndrome.
Social and cultural factors
Sociocultural studies hit highlighted the persona of cultural factors in higher social classes and a higher rate in certain occupational groups ( e.g ballet dancers and nurses ), much as the promotion of thinness as the ideal someone form in Western industrial nations, particularly through the media. A recent epidemiological study of residents indicated that gender, ethnicity and socio-economic status were super influences on the chance of developing anorexia, with those with non-European parents among the least likely to be diagnosed with the condition, and those in wealthy, albescent families being most at risk. People in professions where there is a particular social pressure to be thin (such as models and dancers) were much more likely to amend anorexia during the course of their career, and further research has advisable that those with anorexia hit much higher contact with cultural sources that encourage weight-loss
Prevalence
Case registered data suggest a rate of 1 - 10 per 100,000 females aged between 15 and 34 years.Surveys have suggested a prevalence rate of 1-2% among school girl and university students.
However,many more teen women hit amenorrhoea accompanied by inferior coefficient loss than the 15% required for the dianosis .The information is much inferior common among men ( ratio of 1 : 10 ) .The start in women is usually at between 16 and 17 eld of geezerhood and it seldom occurs after the geezerhood of 30 years.
