The age range of menarche from various populations is very diverse, but it can be said to be normal if menarche occurs at the age of 11-13 years.

Method: The method used was descriptive quantitative from descriptive statistics and probate regression analysis. The variables measured were body weight, height, biceps fat thickness, triceps, sub scapula, abdomen, and also suprailiac.

Results: The results showed that there were 17 students (12.1%) who had menarche. The average age of menarche in this population with a 95% estimate from a probability of 0.5 was 12.3 years.
