Physical activity and sleep quality are factors that play a role in women's hormonal regulation mechanisms. Physical activity affects energy balance and neuroendocrine responses. Sleep quality plays a role in regulating the body's biological rhythms, including reproductive hormones. Differences in physical activity and sleep quality in female students have the potential to indicate a link to menstrual cycle regularity. This study aims to determine the relationship between physical activity and sleep quality and the menstrual cycle in female students in the Nursing and Physical Education, Health, and Recreation Study Programs. The study used a cross-sectional design with 94 samples selected through stratified random sampling. Inclusion criteria included female students aged 19-21 years with a BMI of 18.5-24.9 and who remembered their menstrual periods. Exclusion criteria included marital status, sleeplessness, reproductive or endocrine disease, mobility limitations, and severe stress. The research instruments used included the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index (PSQI), and a menstrual cycle calendar for October-December 2025. Data analysis used the Chi-Square test and Fisher's exact test. Univariate analysis showed that 45.7% of respondents had moderate physical activity, 71.3% had poor sleep quality, and 63.8% had normal menstrual cycles. Bivariate analysis showed a relationship between physical activity and the menstrual cycle, as evidenced by a p-value of 0.001, and a relationship between sleep quality and the menstrual cycle, as evidenced by a p-value of 0.009. Respondents with light to moderate physical activity who had good sleep quality tended to experience normal menstrual cycles. This suggested that physical activity and sleep quality within physiological tolerance support hormonal regulation associated with menstrual cycle regularity.
