The correct answer is 1, 3, 4, and 5.
Here's a breakdown of why:
- Refusal or inability to maintain a normal body weight - This is a key characteristic of anorexia nervosa.
- Repeated episodes of binge eating - This describes bulimia nervosa, not anorexia nervosa.
- Body weight significantly below the average body mass index - This is true for anorexia nervosa.
- Other mental health conditions such as depression and anxiety - Anorexia nervosa is often associated with these conditions.
- Severely distorted body image - This is also a characteristic of anorexia nervosa.
So, options 1, 3, 4, and 5 are all accurate descriptions of anorexia nervosa.
