Menarche that occurs during puberty play a role in the increment of estrogen levels. Adolescents who had experienced menarche tend to have higher estrogen levels.
Methods:Â This was a cross-sectional study with total sampling method. 151 female students in Faculty of Medicine, Universitas Sumatera Utara were included and physical examination on the site of striae was done to confirm diagnosis. Age of menarche is classified as early (â‰¤11 y.o), normal (12-13 y.o) and late (â‰¥14 y.o). StudyÂ was conductedÂ after approval from the Ethics Committee Faculty of Medicine, Universitas Sumatera Utara.

Median (11.0 y.o) and minimum-maximum age of menarche (9-16 y.o). Sites ofÂ striae were found mostly in thighs (66.9%), followed by buttocksÂ (11.8%), calvesÂ (7.4%), hips (6.6%), chest (3.7%), upper arms (2.2%) and breasts (1.4%). Subjects with early menarche were 84 subjects in which 78 with striae and 6 without striae. Subjects with normal and late menarche was 67 subjects with 35 having striae and 32 without striae.
