The menarche age of the participants is 13,3±1,12 (10-17) years old, and there is statistically significance between menarche age and body mass index (p<.001). The other statistically significance was available between menstrual period and weight change (p<.05). It has been found that the menarche age decreases as the students’ weight and BMI increases and the duration of the menstruation cycle increases.
