The data was collected on the anthropometric measurements, menstrual history, lifestyle and psychosocial stress and was correlated with menstrual abnormalities Results: The mean age and standard deviation of girls included in the study were 19.14 years ± 1.136. The Mean age of attaining menarche was 12.96 years ranges were 9-17 years. 52% girls had correct response about actual age of menarche while 45% students have the correct knowledge of duration of blood flow and length of menstrual cycle.
