Question

Quizplus · Accepted Answer

The age at which girls experience menarche is influenced by various factors such as nutrition, health status, body type, and ethnicity. Studies have shown that girls who have a better diet and overall health tend to experience menarche at a later age than those who have poor nutrition and health. Similarly, ethnicity can also play a role, with black girls experiencing menarche earlier than white or Asian girls. Birth order and exposure to media role models have not been consistently linked to the onset of menarche. While physical activity can affect menstrual cycles, it is not a direct cause of menarche.
