Young people mainly girls engage in strict dieting and excessive exercise. This eating disorder in adolescence is known as:

Question

Accepted Answer

While the question describes behaviors common in both Anorexia Nervosa and Bulimia Nervosa, the question *specifically* mentions "excessive exercise" alongside strict dieting. Bulimia Nervosa often involves compensatory behaviors to prevent weight gain after consuming food, and excessive exercise is a common compensatory behavior. Therefore, focusing on the combination of strict dieting *and* excessive exercise, Bulimia Nervosa (Option 4) is the more appropriate answer in this context.

Here's why the other options are incorrect:

*   **Option 1: Anorexia Nervosa:** While strict dieting is a hallmark of Anorexia Nervosa, the question *specifically* highlights "excessive exercise" alongside dieting. While some individuals with Anorexia Nervosa do engage in excessive exercise, it is not as consistently associated with the disorder as it is with Bulimia Nervosa as a compensatory behavior. The question's emphasis on both behaviors makes Bulimia Nervosa a better fit.

*   **Option 2: Obsessive Compulsive Neurosis:** Obsessive Compulsive Disorder (OCD) involves obsessions (intrusive thoughts) and compulsions (repetitive behaviors) aimed at reducing anxiety. While someone with OCD *could* have obsessions related to weight and compulsions related to exercise, the question doesn't describe the underlying obsessive thoughts or the anxiety-reducing function of the behaviors, which are core features of OCD. The question focuses on the eating and exercise behaviors themselves, making Bulimia Nervosa a more direct fit.

*   **Option 3: Neuro-developmental Disorder:** Neuro-developmental disorders are a group of conditions that begin in childhood and affect development. While some neuro-developmental disorders can have associated eating or exercise behaviors, the question doesn't provide any information to suggest a broader developmental issue. The focus is specifically on the dieting and exercise behaviors in adolescence, making Bulimia Nervosa a more specific and relevant answer.
