Data were collected by filling out the International Physical Activity Questionnaire- Short Form (IPAQ-SF) questionnaire to measure physical activity levels, Depression Anxiety Stress Scales (DASS 42) to measure stress levels and height and weight to calculate Body Mass Index (BMI). The results of this study showed that there was no relationship between stress level and menstrual cycle with p-value 0.299 (>0.05), no relationship between physical activity and menstrual cycle with p-value 0.954 (>0.05), and no relationship between Body Mass Index (BMI) and menstrual cycle with p-value 0.722 (>0.05). The conclusion of this study is that stress level, physical activity and Body Mass Index (BMI) are not associated with menstrual cycle.]]>
