The media is an important factor in determining the increased incidence of anorexia nervosa: according to a 2000 study by Tiggemann et al., "the factor that exerted the strongest pressure to be thin was the media ". Social media, in particular, has led to the epidemic of anorexia among young women. A study conducted by Field et al. (2001) argued that the media is responsible for encouraging girls to pursue the idea of ​​achieving an unrealistically thin body type. People are constantly bombarded with advertisements and posts from the various social media sites they are members of; some posts found on these sites evoke negative feelings and perceptions regarding body image. Such emotions can lead to a variety of behaviors aimed at altering one's appearance, such as excessive dieting and excessive physical activity. Taken to the extreme, such behaviors are diagnostic of anorexia nervosa, considered one of the deadliest mental illnesses (Birmingham et al. 2005). According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSMV), anorexia has two subtypes and its diagnostic criteria include three elements. The two subtypes are the restrictive subtype, when you are unable to eat, and the binge/purge subtype, when you eat excessive amounts and then purge. Elimination can be provoked with laxatives or by inducing vomiting with a finger or an object. According to the latest edition of the DSM (American Psychiatric Association, 2013), the diagnostic criteria for anorexia nervosa are divided into three parts: The first is the refusal to maintain body weight at a normal level (the weight calculated based on your age and height) or the inability to achieve the expected weight gain for a period of growth. The second is the intense fear of wei......middle of paper......behaviors on Pinterest.
