Identify a true statement about the onset of menstruation, termed "menarche."

Question

Quizplus · Accepted Answer

The onset of menstruation, or menarche, occurs at about 12½ years of age on average. While there may be some variation in timing due to genetic, nutritional, and environmental factors, there is not a great deal of consistency and predictability in its timing. Ethnicity can also play a role in the timing of menarche, with African American girls typically reaching menarche earlier than European American girls, and Latina girls reaching menarche at a similar age to European American girls. There is no evidence to suggest that Asian American girls reach menarche several months later than Latina girls.
