Which condition increases the risk of osteoporosis in teenagers?

1. Regular physical activity

2. Healthy dietary habits

3. Anorexia nervosa

4. High intake of calcium

The correct answer is: Anorexia nervosa

Anorexia nervosa significantly increases the risk of osteoporosis in teenagers due to the condition's impact on nutrition and body composition. This eating disorder typically involves severe calorie restriction, often leading to malnutrition and deficiencies in essential nutrients, including calcium and vitamin D, which are critical for bone health. During the teenage years, individuals are still in a crucial phase of bone development and density accumulation. When the body does not receive enough nutrients, particularly during this period of growth, it can lead to decreased bone mass and increased fragility over time. Consequently, adolescents suffering from anorexia nervosa face a higher likelihood of developing osteoporosis later in life due to inadequate bone formation and preservation during these formative years.
