The Menstrual Cycle is obtained through an interview using a questionnaire. The results showed that the diet is sufficient as much 39,9%, the diet is less as much 60,1%. Nutritional status is less by 31,2%, good nutritional status is 52,2%, nutritional status is more by 7,2%. A normal menstrual cycle of 78,3%, an abnormal menstrual cycle of 21,7%. The results of statistical tests between dietary variables and nutritional status with the menstrual cycle showed no relationship between diet and menstrual cycle and no relationship between nutritional status and menstrual cycle.
